Description

Technical Field

[0001] This disclosure relates to a bundle of dimming sheets. Background Technology

[0002] The first example of the aforementioned bundled body includes a laminated body and a pair of protective plates sandwiching the laminated body. The laminated body includes a plate-shaped substrate and a protective film disposed on at least one of the pair of main surfaces of the plate-shaped substrate (see, for example, Patent Document 1). As an example of a plate-shaped substrate, a dimming sheet includes a first transparent electrode film, a second transparent electrode film, and a dimming layer sandwiched between the first transparent electrode film and the second transparent electrode film. The dimming layer includes a liquid crystal composition. The outer periphery of the dimming sheet includes a sealing portion that seals the gap between the first transparent electrode film and the second transparent electrode film in the dimming layer.

[0003] The second example of the aforementioned bundle is a roller on which a plastic film is wound around a cylindrical core. The starting point of the winding of the plastic film is adhered to the core by a one-sided adhesive tape. Thus, the starting point, which is the part where the plastic film begins to be wound, is fixed to the cylindrical core (see, for example, Patent Document 2).

[0043] (First Implementation)

[0044] [Composition of dimming sheets]

[0045] The dimming sheet 11 has a first surface and a second surface opposite to the first surface. The first surface and the second surface extend along the extension direction of the dimming sheet 11, respectively. Figure 1 The planar structure of the dimming sheet 11 is shown as viewed from a viewpoint opposite the first face of the dimming sheet 11.

[0046] like Figure 1 As shown, the dimming sheet 11 can also have a rectangular shape. The dimming sheet 11 can also include a pair of flexible wiring substrates 12. The pair of flexible wiring substrates 12 can be connected to the outer periphery 13 of the dimming sheet 11 and disposed on one side of the dimming sheet 11. The side where the flexible wiring substrates 12 are disposed can be either the long side or the short side of the dimming sheet 11. The side where the flexible wiring substrates 12 are disposed can also be determined based on the configuration of the driving circuit in the dimming sheet 11, the shape of the object to which the dimming sheet 11 is applicable, etc.

[0047] like Figure 2As shown, the dimming sheet 11 includes a first transparent electrode film 11a, a second transparent electrode film 11d, a dimming layer 11g, and a sealing portion 11h. The dimming layer 11g is inserted into the gap between the first transparent electrode film 11a and the second transparent electrode film 11d. The sealing portion 11h seals the gap between the first transparent electrode film 11a and the second transparent electrode film 11d at the outer periphery 13 of the dimming sheet 11. The dimming layer 11g is inserted into the gap surrounded by the sealing portion 11h.

[0048] The dimming layer 11g comprises a transparent polymer layer and a liquid crystal composition. The transparent polymer layer is divided to fill the voids in the liquid crystal composition. The liquid crystal composition fills the voids in the transparent polymer layer. Due to the refractive index difference between the transparent polymer layer and the liquid crystal composition, the visible light entering the dimming layer 11g is scattered by the voids divided by the transparent polymer layer, thereby making the dimming layer 11g cloudy.

[0049] The liquid crystal composition can be held in any one of the following forms: polymer dispersion, polymer network, and capsule. In a polymer dispersion form, the liquid crystal composition is held within the voids dispersed in a transparent polymer layer, which contains multiple independent voids. In a polymer network form, the liquid crystal composition is held within the interconnected voids of a transparent polymer network with a three-dimensional mesh-like structure. A polymer network is one example of a transparent polymer layer. In a capsule form, a capsule-shaped liquid crystal composition is held within a transparent polymer layer. Furthermore, in addition to the liquid crystal compound, the liquid crystal composition may also contain monomers, oligomers, dichroic pigments, plasticizers, etc., used to form the transparent polymer layer. The dimming layer 11g may also include spacers for maintaining the thickness of the dimming layer 11g within a certain range.

[0050] The first transparent electrode film 11a includes a first transparent substrate 11b and a first transparent electrode layer 11c. The first transparent substrate 11b supports the first transparent electrode layer 11c. The first transparent substrate 11b has a first surface that forms the surface of the dimming sheet 11. The second transparent electrode film 11d includes a second transparent substrate 11e and a second transparent electrode layer 11f. The second transparent substrate 11e supports the second transparent electrode layer 11f. The second transparent substrate 11e has a second surface that forms the surface of the dimming sheet 11.

[0051] The first transparent electrode film 11a may have an alignment layer disposed between the first transparent electrode layer 11c and the dimming layer 11g, and may also have a hard coating layer disposed on the side opposite to the first transparent electrode layer 11c. The second transparent electrode film 11d may have an alignment layer disposed between the second transparent electrode layer 11f and the dimming layer 11g, and may also have a hard coating layer disposed in the second transparent substrate 11e on the side opposite to the second transparent electrode layer 11f.

[0052] The flexible wiring substrate 12 has an extension 12a extending outward toward the first transparent electrode film 11a and the second transparent electrode film 11d in the extended surface direction of the dimming sheet 11. One of the pair of flexible wiring substrates 12 is electrically connected to the first transparent electrode layer 11c. The other of the pair of flexible wiring substrates 12 is electrically connected to the second transparent electrode layer 11f. The pair of flexible wiring substrates 12 apply a driving voltage to the dimming layer 11g.

[0053] In a normal type of dimming sheet 11, even without an electric field between the transparent electrode layers 11c and 11f, the long axis of the liquid crystal compound can be irregularly aligned to scatter light incident on the dimming sheet 11, thereby making the dimming sheet 11 opaque. Alternatively, in a normal type of dimming sheet 11, even with an electric field between the transparent electrode layers 11c and 11f, the long axis of the liquid crystal compound can follow the electric field to allow light incident on the dimming sheet 11 to pass through, thereby making the dimming sheet 11 transparent.

[0054] In the reverse-type dimming sheet 11, even without an electric field formed between the transparent electrode layers 11c and 11f, the long axis direction of the liquid crystal compound follows the confinement force of the alignment layer, thereby making the dimming sheet 11 transparent. Alternatively, in the reverse-type dimming sheet 11, even with an electric field formed between the transparent electrode layers 11c and 11f, the long axis direction of the liquid crystal compound follows the electric field, causing light incident on the dimming sheet 11 to scatter, thereby making the dimming sheet 11 opaque.

[0055] The dimming sheet 11 can reversibly switch from transparent to opaque. The first side of the dimming sheet 11 can also be adhered to transparent objects such as window glass, partitions, and display cases. Alternatively, the first side of the dimming sheet 11 can be adhered to a first transparent plate, and the second side of the dimming sheet 11 can be adhered to a second transparent plate, with the dimming sheet 11 sandwiched between the two transparent plates. The dimming sheet 11 can also be used as a projection screen.

[0056] [Composition of Protective Body 51]

[0057] like Figure 3 As shown, the protective body 51 includes a dimming sheet 11, a first protective sheet 21, and a second protective sheet 22. The first protective sheet 21 and the second protective sheet 22 constitute a bundling component.

[0058] The first protective sheet 21 is larger than the dimming sheet 11. When viewed from a viewpoint opposite to the first surface of the dimming sheet 11, the outer periphery of the first protective sheet 21 protrudes from the dimming sheet 11. The second protective sheet 22 is larger than the dimming sheet 11. When viewed from a viewpoint opposite to the second surface of the dimming sheet 11, the outer periphery of the second protective sheet 22 protrudes from the dimming sheet 11.

[0059] Each protective sheet 21 and 22 covers the entire dimming sheet 11. Two protective sheets 21 and 22 sandwich the entire dimming sheet 11. The first protective sheet 21 is in contact with the first surface of the dimming sheet 11. The first protective sheet 21 protects the entire first surface of the dimming sheet 11. The second protective sheet 22 is in contact with the second surface of the dimming sheet 11. The second protective sheet 22 protects the entire second surface of the dimming sheet 11. Each protective sheet 21 and 22 may have an adhesive layer that is easily peelable from the dimming sheet 11, or it may not have adhesive properties relative to the dimming sheet 11.

[0060] The protective body 51 includes a first protective plate 31 and a second protective plate 32. The first protective plate 31 and the second protective plate 32 constitute a bundling component.

[0061] The first protective plate 31 is larger than the dimming sheet 11. When viewed from a viewpoint opposite to the first surface of the dimming sheet 11, the outer periphery of the first protective plate 31 protrudes from the dimming sheet 11. The outer periphery of the first protective plate 31 may or may not protrude from the first protective sheet 21. The first protective plate 31 is in contact with the first protective sheet 21.

[0062] The second protective plate 32 is larger than the dimming sheet 11. When viewed from a viewpoint opposite the second surface of the dimming sheet 11, the outer periphery of the second protective plate 32 protrudes from the dimming sheet 11. The outer periphery of the second protective plate 32 may or may not protrude from the second protective sheet 22. The second protective plate 32 is in contact with the second protective sheet 22.

[0063] Two protective plates 31 and 32 sandwich two protective sheets 21 and 22. The two protective plates 31 and 32 cover the entire dimming sheet 11. The two protective plates 31 and 32 sandwich the entire dimming sheet 11. The first protective plate 31 protects the entire first side of the dimming sheet 11. The second protective plate 32 protects the entire second side of the dimming sheet 11.

[0064] A protective body 51 is composed of a first protective plate 31, a second protective plate 32, and multiple sheets sandwiched between the two protective plates 31 and 32. The multiple sheets are the first protective sheet 21, the dimming sheet 11, and the second protective sheet 22.

[0065] When it is required to suppress friction on the surface of the dimming sheet 11, each protective sheet 21, 22 is preferably elastic. When it is required to suppress localized pressure on the dimming sheet 11, each protective sheet 21, 22 is preferably elastic. Each protective sheet 21, 22 may also be a foamed sheet. A foamed sheet is a cushioning material containing independent air bubbles and having elasticity.

[0066] When lightweighting and high strength are required for the protective body 51, each protective plate 31 and 32 is preferably lightweight and high-strength. Each protective plate 31 and 32 may also be corrugated cardboard with a bi-wall (registered trademark) structure and a thickness of 10 mm or more. The bi-wall (registered trademark) structure is a corrugated cardboard structure reinforced by bonding two sheets of corrugated paper together. Each protective plate 31 and 32 may also be corrugated paper made of plastic.

[0067] Each protective plate 31, 32 may also be rectangular. Rectangular shapes of the protective plates 31, 32 facilitate handling of the protective body 51 during bundling and transport. The corners of each protective plate 31, 32 may be rounded or chamfered at 45°.

[0068] like Figure 4 As shown, multiple parts of the first protective sheet 21 are peelably fixed to the first protective plate 31 using adhesive tape 17. Figure 4 An example is shown where the size of the first protective plate 31 is the same as the size of the first protective sheet 21.

[0069] Multiple portions of the outer periphery of the first protective plate 31 are respectively fixed to one side of the outer periphery of the first protective sheet 21 by adhesive tape 17. The adhesive tape 17 is easy to peel off. The adhesive tape 17 inhibits the positional displacement of the first protective sheet 21 relative to the first protective plate 31. The adhesive tape 17 can be easily peeled off from the first protective plate 31 and the first protective sheet 21.

[0070] The surfaces of the outer periphery of the first protective plate 31 opposite the first protective sheet 21 and the outer periphery of the first protective sheet 21 opposite the first protective plate 31 can also be fixed together by adhesive tape with adhesive layers on both sides. The surfaces of the first protective plate 31 and the first protective sheet 21 can also be fixed together by adhesive tape with adhesive layers on both sides, both inside the outer periphery of the first protective plate 31 and inside the outer periphery of the first protective sheet 21. Preferably, the portion of the first protective sheet 21 fixed to the first protective plate 31 is the outer side of the dimming sheet 11. This suppresses positional displacement of the dimming sheet 11 relative to the first protective plate 31.

[0071] The outer periphery of the first protective plate 31 may also protrude from the outer periphery of the first protective sheet 21. Multiple portions of the outer periphery of the first protective sheet 21 may also be fixed to the surface of the first protective plate 31 using adhesive tape 17 with an adhesive layer on one side.

[0072] When the first protective plate 31 has a rectangular shape, two or more portions of the first protective sheet 21 can also be fixed to one side of the first protective plate 31. The number of portions of the first protective sheet 21 fixed to the first protective plate 31 can also be appropriately changed according to the size of the first protective plate 31.

[0073] Multiple portions of the second protective plate 32 are peelably fixed to the second protective sheet 22 by adhesive tape 17. Figure 4 An example is shown where the size of the second protective plate 32 is the same as that of the second protective sheet 22. Multiple portions of the outer periphery of the second protective plate 32 are fixed to one side of the outer periphery of the second protective sheet 22 using adhesive tape 17. This suppresses positional displacement of the second protective sheet 22 relative to the second protective plate 32.

[0074] The surfaces of the second protective plate 32 and the second protective sheet 22 that face each other on their outer periphery can be fixed together using adhesive tape with adhesive layers on both sides. The surfaces of the second protective plate 32 and the second protective sheet 22 can also be fixed together using adhesive tape with adhesive layers on both sides, on sides further inward than the outer periphery of the second protective plate 32 and further inward than the outer periphery of the second protective sheet 22. Preferably, the portion of the second protective sheet 22 fixed to the second protective plate 32 is the outer side of the dimming sheet 11. This suppresses positional displacement of the dimming sheet 11 relative to the second protective plate 32.

[0075] The outer periphery of the second protective plate 32 may also protrude from the outer periphery of the second protective sheet 22. Multiple portions of the outer periphery of the second protective sheet 22 may also be fixed to the surface of the first protective plate 31 using adhesive tape 17 with an adhesive layer on one side.

[0076] When the second protective plate 32 has a rectangular shape, two or more portions of the second protective sheet 22 can also be fixed to one side of the second protective plate 32. The number of portions of the second protective sheet 22 fixed to the second protective plate 32 can also be appropriately changed according to the size of the second protective plate 32.

[0077] The protective body 51 has a first easily peelable band 16a.

[0078] The first easy-peel tape 16a covers the entire sealing portion 11h and secures the dimming sheet 11 to the first protective sheet 21. The first easy-peel tape 16a covers the entire outer periphery 13 of the dimming sheet 11.

[0079] Each edge of the dimming sheet 11 can be fixed to the first protective sheet 21 by different first easy-peel strips 16a, or by a single first easy-peel strip 16a. The adhesive force per unit bonding area of ​​the first easy-peel strip 16a is the amount of adhesive component of the first easy-peel strip 16a remaining on the substrate of the first easy-peel strip 16a when the protective body 51 is unpacked, and the amount of adhesive component of the first easy-peel strip 16a that is not easily left on the surface of the dimming sheet 11.

[0080] A portion of the first peelable strip 16a can also fix the base end portion 12b of the extension portion 12a of the flexible wiring substrate 12 to the first protective sheet 21. One of the four sides of the first peelable strip 16a can also fix the base end portion 12b of the extension portion 12a of the flexible wiring substrate 12 to the first protective sheet 21.

[0081] The protective body 51 has a second easy-peel strip 16b. The second easy-peel strip 16b secures the front end portion 12c of the extension 12a of the flexible wiring substrate 12 to the first protective sheet 21.

[0082] The front end 12c of each flexible wiring substrate 12 can be fixed to the first protective sheet 21 by different second easy-peel strips 16b, or by a single longer second easy-peel strip 16b. The adhesive force per unit adhesive area of ​​the second easy-peel strip 16b is the amount of adhesive component of the second easy-peel strip 16b remaining on the substrate of the second easy-peel strip 16b when the protective body 51 is unpacked, and the amount of adhesive component of the second easy-peel strip 16b that is not easily left on the surface of the flexible wiring substrate 12.

[0083] Fixing the base end 12b of the flexible wiring substrate 12 to the peelable strip of the first protective sheet 21 can also be different from fixing the front end 12c to the second peelable strip 16b of the first protective sheet 21.

[0084] like Figure 5 As shown, the end face of the outer periphery 13 of the dimming sheet 11 has a sealing portion 11h. The adhesive surface of the first easy-peel tape 16a can also be in close contact with the adhesive surface that serves as the sealing portion 11h. The adhesive surface of the first easy-peel tape 16a can also be in close contact with the adhesive surface that serves as the end face of the first transparent electrode film 11a. The adhesive surface of the first easy-peel tape 16a is in close contact with the adhesive surface that serves as the surface of the first protective sheet 21. The adhesive surface of the first easy-peel tape 16a can also be bonded using a tool such as a scraper. The scraper is an elastic component such as plastic or rubber. Regarding the bonding of the first easy-peel tape 16a, by pressing the first easy-peel tape 16a toward the end face of the dimming sheet 11, the air trapped between the adhesive surface and the adhesive surface is pushed out from between the adhesive surface and the adhesive surface and discharged.

[0085] The air trapped between the adhesive surface and the bonded surface reduces the adhesive area and the amount of air present, thus decreasing the adhesive force between the adhesive surface and the bonded surface. The expulsion of the air trapped between the adhesive surface and the bonded surface increases the adhesive area of ​​the first easy-peel strip 16a. As a result, the adhesive force between the sealing portion 11h and the first easy-peel strip 16a, the adhesive force between the first transparent electrode film 11a and the first easy-peel strip 16a, and the adhesive force between the first protective sheet 21 and the first easy-peel strip 16a are increased. The adhesive surface of the first easy-peel strip 16a is also pressed tightly against the corner 18 formed by the end face of the first transparent electrode film 11a and the surface of the first protective sheet 21 by a scraper or similar tool.

[0086] Four first easy-peel strips 16a cover the entire outer periphery 13 of the dimming sheet 11. The first easy-peel strips 16a cover the entire outer periphery 13 of the dimming sheet 11, conforming to the shape of the end faces within the outer periphery 13. This fixing method, which increases the bonding area of ​​the first easy-peel strips 16a, suppresses positional displacement of the dimming sheet 11 relative to the first protective sheet 21. The first easy-peel strips 16a, with their lower adhesive force per unit bonding area, increase the bonding area to secure the dimming sheet 11 to the first protective sheet 21.

[0087] The first peelable tape 16a preferably has a wide width to increase the bonding area relative to the first protective sheet 21. For example, a masking tape with a width of 30 mm can be used. However, the width of the peelable tape alone is insufficient to obtain a sufficient bonding area of ​​the first peelable tape 16a relative to the sealing portion 11h. When using a wide peelable tape, the first peelable tape 16a is also preferably designed to cover the entire outer periphery 13 of the dimming sheet 11 in accordance with the shape of the end face in the outer periphery 13 of the dimming sheet 11.

[0088] The protective body 51 is preferably secured to the two protective plates 31 and 32 by adhesive tape 17. For example, it is preferable to use adhesive tape 17 at least at one location on one side, thereby securing the outer periphery of the first protective plate 31 to the outer periphery of the second protective plate 32 on four sides. Thus, the protective body 51 is treated as a single unit, and the surface of the second protective sheet 22 is less likely to rub against the surface of the dimming sheet 11.

[0089] [Composition of the bundle]

[0090] like Figure 6 As shown, the bundle 100 includes a protective body 51. The bundle 100 winds a stretch film 41 around the protective body 51 such that a second protective plate 32 is pressed against a first protective plate 31. The stretch film 41 is wound more than two turns onto the protective body 51 in mutually orthogonal directions, such as longitudinal and transverse. The tight adhesion between the two or more turns of the stretch film 41 prevents slackness of the stretch film 41.

[0091] In cases where further quality protection of the dimming sheet 11 is required, each protective plate 31, 32 is preferably deformable in the thickness direction. The deformation of each protective plate 31, 32 in the thickness direction causes its surface shape to follow the surface shape of the dimming sheet 11. The deformation of each protective plate 31, 32 suppresses deformation of the dimming sheet 11 and also suppresses positional displacement of the dimming sheet 11 relative to each protective plate 31, 32 in the planar direction.

[0092] Furthermore, the corners of the rectangular bundle 100 are relatively less susceptible to impact within the end face of the bundle 100. Preferably, plastic strips are adhered to the four corners of the bundle 100 and secured by crimping. During transport, deformation of the corners is suppressed when impact is applied to the corners of the bundle 100. The crimping of the four corners based on the plastic strips further secures the second protective plate 32 relative to the first protective plate 31.

[0093] The outermost periphery of the bundle 100 is preferably entirely covered by bubble wrap. Bubble wrap, for example, is a sheet formed by sealing air within cylindrical protrusions, such as PetitPetit (registered trademark) or AirCap (registered trademark). The bubble wrap cushions the impact on the dimming sheet 11 during transport. Preferably, the bundle 100 uses a double layer of bubble wrap to completely cover the protective body 51.

[0094] [Manufacturing method of the bundle]

[0095] The manufacturing method of the bundle 100 is described below. The bundle 100 is manufactured according to the following operating steps.

[0096] (a) A first protective plate 31, which is at least 10 cm larger in both length and width than the dimming sheet 11, is placed on the worktable. A first protective sheet 21, which is the same size as the first protective plate 31, is overlapped on the first protective plate 31. The first protective sheet 21 is fixed to the first protective plate 31 at more than 8 points using adhesive tape 17.

[0097] (b) The dimming sheet 11 with the product label facing upwards is positioned in the center of the first protective sheet 21. The entire outer periphery 13 of the dimming sheet 11, including the corners, is secured to the first protective sheet 21 by a first easy-peel tape 16a.

[0098] (c) The adhesive surface of the first easy-peel tape 16a follows the shape of the end face in the outer periphery 13 of the dimming sheet 11 and is tightly attached to the outer periphery 13 using a tool such as a scraper. The base end 12b and the front end 12c of the flexible wiring substrate 12 are fixed by the second easy-peel tape 16b.

[0099] (d) A second protective sheet 22 of the same size as the first protective sheet 21 is overlapped on the dimming sheet 11. A second protective plate 32 of the same size as the second protective sheet 22 is overlapped on the second protective sheet 22. The second protective plate 32 is fixed to the second protective sheet 22 at more than 8 locations using adhesive tape 17.

[0100] (e) Each protective plate 31, 32 is fixed in at least four locations using adhesive tape 17. A label sticker indicating that the packaged product is affixed to the upper surface of the second protective plate 32.

[0101] (f) For the first protective plate 31, the second protective plate 32, and the multiple sheets sandwiched between the protective plates 31 and 32, a stretch film 41 is wound at least two turns in both the longitudinal and transverse directions. Plastic strips are attached to the four corners. The first protective plate 31 is pressed against the multiple sheets, and the multiple sheets are pressed against the second protective plate 32. The entire protective body 51 is double-layered with bubble wrap. Finally, a label indicating that the bundled product is attached to the bundle 100, and the bundling operation is completed.

[0102] [effect]

[0103] The outer periphery 13 of the dimming sheet 11 is fixed to the first protective sheet 21. Therefore, it is less likely for the sealing portion 11h to shift relative to the first protective sheet 21. The first protective sheet 21 is fixed to the first protective plate 31. Therefore, it is less likely for the first protective sheet 21 to shift relative to the first protective plate 31. The second protective sheet 22 is fixed to the second protective plate 32. Therefore, it is less likely for the second protective sheet 22 to shift relative to the second protective plate 32. Furthermore, the first protective plate 31 is fixed to the second protective plate 32, thereby forming a protective body 51. As a result, it is possible to suppress the positional shift of the second protective plate 32 relative to the first protective plate 31. In the protective body 51, it is possible to suppress the friction of the sealing portion 11h caused by the positional shift of the sealing portion 11h.

[0104] The protective body 51 applies pressure to the dimming sheet 11 in the thickness direction through the stretching membrane 41. Due to the pressure, the protective plates 31 and 32 constituting the protective body 51 deform along the surface shape of the dimming sheet 11. Therefore, within the protective body 51, positional displacement of the sealing portion 11h caused by vibration can be suppressed. At this time, deformation of the protective sheets 21 and 22, and peeling of the easy-peel strips 16a and 16b caused by the pressure applied to the dimming sheet 11 can be suppressed. Therefore, friction of the sealing portion 11h caused by positional displacement of the dimming sheet 11 can be suppressed.

[0105] In particular, when conveying the bundle 101, if the bundle 101 is stacked longitudinally, vibration along the surface direction of the dimming sheet 11, which is the direction of gravity, causes the dimming sheet 11 to shift in the surface direction. Longitudinal stacking refers to conveying the bundle 101 with the surface of the dimming sheet 11 in a vertical position. On the other hand, if pressure is applied to the thickness direction of the dimming sheet 11, the position of the dimming sheet 11 is less likely to shift relative to each of the protective plates 31, 32 in the direction of gravity. Regardless of the stacking direction during conveying, the position of the dimming sheet 11 is less likely to shift. Therefore, friction of the sealing portion 11h can be suppressed. Suppressing friction on the surface of the dimming sheet 11 is to protect the quality of the dimming sheet 11, such as the required aesthetic appearance and the required durability. Suppressing friction in the sealing portion 11h is to protect the sealing performance of the liquid crystal compound required for the sealing portion 11h, the cleanliness of the appearance of the sealing portion 11h, and other qualities of the dimming sheet 11.

[0106] According to the first embodiment, the following effects can be obtained.

[0107] (1-1) Protects both sides of the dimming sheet 11 from friction caused by vibration during transport. Therefore, damage caused by friction can be suppressed. In addition, the performance degradation of the sealing part 11h caused by the sealing part 11h peeling off from the dimming sheet 11 can be suppressed.

[0108] (1-2) Because the contact area between the first peelable strip 16a and the outer peripheral portion 13 is large, the adhesive strength of the first peelable strip 16a is improved. Therefore, the positional displacement of the sealing portion 11h relative to the first protective sheet 21 can be suppressed.

[0109] (1-3) The first peelable strip 16a secures the base end portion 12b of the extension 12a to the first protective sheet 21. The second peelable strip 16b secures the front end portion 12c of the extension 12a to the first protective sheet 21. Therefore, the position of the flexible wiring substrate 12 is less likely to shift in the planar direction relative to the first transparent electrode film 11a and the first protective sheet 21. As a result, stress applied to the joint portion between the first transparent electrode film 11a and the flexible wiring substrate 12 can be suppressed.

[0110] (1-4) The first peelable strip 16a secures the base end portion 12b of the extension 12a to the first protective sheet 21. The second peelable strip 16b secures the front end portion 12c of the extension 12a to the first protective sheet 21. Therefore, the position of the flexible wiring substrate 12 is less likely to shift relative to the second transparent electrode film 11d and the first protective sheet 21. As a result, stress applied to the joint between the second transparent electrode film 11d and the flexible wiring substrate 12 can be suppressed.

[0111] (1-5) The first protective plate 31 and the first protective sheet 21 are fixed at multiple locations using adhesive tape 17. The second protective plate 32 and the second protective sheet 22 are fixed at multiple locations using adhesive tape 17. As a result, the position of the first protective sheet 21 is less likely to shift relative to the first protective plate 31 in the planar direction. The position of the second protective sheet 22 is less likely to shift relative to the second protective plate 32 in the planar direction. Therefore, it is possible to suppress the downward movement of the position of the dimming sheet 11 and the first protective sheet 21 together, and the downward movement of the position of the dimming sheet 11 and the second protective sheet 22 together, caused by vibration during transport with the surface of the dimming sheet 11 perpendicular to the direction.

[0112] (1-6) The bundle 100 winds the stretch film 41 such that the second protective plate 32 is pressed against the first protective plate 31. Pressure based on the stretch film 41 is applied to the bundle 100 from a direction perpendicular to the surface of the dimming sheet 11 sandwiched between the two protective plates 31, 32. Therefore, positional displacement of the dimming sheet 11 in the surface direction can be further suppressed.

[0113] (Second Implementation)

[0114] The structure of the bundle 101 for transporting or storing multiple dimming sheets 11 will be described. Hereinafter, the structure of the bundle 101 that is different from that of the bundle 100 will be mainly described, and the descriptions that are repeated with the bundle 100 will be omitted.

[0115] [Composition of the bundle]

[0116] like Figure 7 As shown, a first protective plate 31, a second protective plate 32, and multiple sheets sandwiched between the protective plates 31 and 32 constitute a protective body 51. The multiple sheets are the first protective sheet 21, the dimming sheet 11, and the second protective sheet 22.

[0117] The bundle 101 has multiple stacked protective bodies 51. In adjacent protective bodies 51, the first protective plate 31 in one protective body 51 is the second protective plate 32 in another protective body 51. In other words, the bundle 101 has a first protective plate 31, a second protective plate 32, and multiple third protective plates 33. In the protective body 51 with the third protective plate 33 as the upper protective plate, the third protective plate 33 is the second protective plate 32. In the protective body 51 with the third protective plate 33 as the lower protective plate, the third protective plate 33 is the first protective plate 31.

[0118] like Figure 6 As shown, the bundle 101 is wrapped with a stretch film 41 in a manner that presses the second protective plate 32 against the first protective plate 31 among a plurality of stacked protective bodies 51. The plurality of stacked protective bodies 51 are secured by the stretch film 41, for example, by being wound more than two turns in both the longitudinal and transverse directions.

[0119] Preferably, the first protective plate 31, the second protective plate 32, and the third protective plate 33 are deformable in the thickness direction when the stretch film 41 is wound. The deformation of the first protective plate 31, the second protective plate 32, and the third protective plate 33 in the thickness direction causes their surface shapes to follow the surface shape of the dimming sheet 11. This suppresses deformation of the dimming sheet 11 in the thickness direction. Furthermore, it suppresses positional displacement of the dimming sheet 11 relative to the first protective plate 31, the second protective plate 32, and the third protective plate 33 in the surface direction.

[0120] The third protective plate 33, which is more numerous than each of the protective plates 31 and 32, is thinner than each of the protective plates 31 and 32. As a result, the overall thickness of the bundle 101 is reduced. This allows for the bundling of more protective bodies 51 while maintaining a relatively thin bundle 101.

[0121] [Manufacturing method of the bundle]

[0122] Next, the manufacturing method of the bundle 101 will be explained.

[0123] The bundle 101 is manufactured according to the following operating steps.

[0124] (a) A first protective plate 31, which is at least 10 cm larger in both length and width than the dimming sheet 11, is placed on the worktable. A first protective sheet 21, which is the same size as the first protective plate 31, is overlapped on the first protective plate 31. The first protective sheet 21 is fixed to the first protective plate 31 at more than 8 points using adhesive tape 17.

[0125] (b) The dimming sheet 11 with the product label facing upwards is positioned in the center of the first protective sheet 21. The entire outer periphery 13 of the dimming sheet 11, including the corners, is secured to the first protective sheet 21 by a first easy-peel tape 16a.

[0126] (c) The adhesive surface of the first easy-peel tape 16a follows the shape of the end face in the outer periphery 13 of the dimming sheet 11 and is tightly attached to the outer periphery 13 using a tool such as a scraper. The base end 12b and the front end 12c of the flexible wiring substrate 12 are fixed by the second easy-peel tape 16b.

[0127] (d) A second protective sheet 22 of the same size as the first protective sheet 21 is overlapped on the dimming sheet 11. A third protective plate 33 of the same size as the second protective sheet 22 is overlapped on the second protective sheet 22. The third protective plate 33 is fixed to the second protective sheet 22 at more than 8 locations using adhesive tape 17.

[0128] (e) A first protective sheet 21 of the same size as the third protective plate 33 is overlapped on the third protective plate 33. The first protective sheet 21 is fixed to the third protective plate 33 at more than 8 locations using adhesive tape 17.

[0129] (f) The dimming sheet 11 with the product label facing upwards is positioned in the center of the first protective sheet 21. The entire outer periphery 13 of the dimming sheet 11, including the corners, is secured to the first protective sheet 21 by a first easy-peel tape 16a.

[0130] (g) The adhesive surface of the first easy-peel tape 16a follows the shape of the end face in the outer periphery 13 of the dimming sheet 11 and is tightly attached to the outer periphery 13 using a tool such as a scraper. The base end 12b and the front end 12c of the flexible wiring substrate 12 are fixed to the first protective sheet 21 using the second easy-peel tape 16b.

[0131] (h) Repeat steps (d) to (g) until all the bundled dimming sheets 11 are stacked. Furthermore, if the thickness of the bundle 101 increases, the shape of the bundle 101 after winding the stretch film 41 will be unstable. Preferably, the number of dimming sheets 11 bundled in one bundle 101 is 10 sheets or less.

[0132] (i) If all the dimming sheets 11 used for bundling are stacked, a second protective sheet 22 of the same size as the first protective sheet 21 is overlapped on top of the dimming sheets 11. A second protective plate 32 of the same size as the second protective sheet 22 is disposed on top of the second protective sheet 22. The second protective plate 32 is fixed to the second protective sheet 22 at more than 8 locations using adhesive tape 17.

[0133] (j) The first protective plate 31 is fixed to the second protective plate 32 at four or more locations using adhesive tape 17. A label sticker indicating that the product is bundled is adhered to the upper surface of the second protective plate 32.

[0134] (k) For the first protective plate 31, the second protective plate 32, and the multiple sheets sandwiched between the two protective plates 31 and 32, a stretch film 41 is wound at least two turns in both the longitudinal and transverse directions. The multiple sheets are secured to the first protective plate 31 and the second protective plate 32. Plastic strips are adhered to the four corners. The first protective plate 31 is pressed against the multiple sheets, and the multiple sheets are pressed against the second protective plate 32. The entire protective body 51 is double-layered with bubble wrap. Finally, a label indicating that the bundled product is being bundled is adhered to the bundle 101, and the bundling operation is complete.

[0135] [effect]

[0136] Next, the function of this embodiment will be explained.

[0137] The outer periphery 13 of the dimming sheet 11 is entirely fixed to the first protective sheet 21. Therefore, positional displacement of the sealing portion 11h in the dimming sheet 11 relative to the first protective sheet 21 can be suppressed. The first protective sheet 21 is fixed to the first protective plate 31. Therefore, positional displacement of the first protective sheet 21 relative to the first protective plate 31 can be suppressed. The first protective plate 31 is fixed relative to the second protective plate 32. Thus, a plurality of protective bodies 51 are formed. Therefore, positional displacement of the second protective plate 32 relative to the first protective plate 31 can be suppressed within the plurality of protective bodies 51.

[0138] Multiple protective bodies 51 are subjected to pressure by a stretching film 41 along the thickness direction of the dimming sheet 11. The first protective plate 31, the second protective plate 32, and the third protective plate 33 constituting the multiple protective bodies 51 deform along the surface shape of the dimming sheet 11 due to the pressure. Therefore, the positional displacement of the sealing portion 11h in the dimming sheet 11 caused by vibration can be suppressed inside each protective body 51.

[0139] In particular, when conveying the bundle 101, if the bundle 101 is stacked longitudinally, a large force is generated that would cause the dimming sheet 11 to shift along the surface direction due to vibration in the direction of gravity. Longitudinal stacking refers to conveying the bundle 101 with the surface of the dimming sheet 11 in a vertical position. On the other hand, by applying pressure along the thickness direction of the dimming sheet 11, it is difficult for the dimming sheet 11 to shift relative to each of the protective plates 31 and 32 in the direction of gravity. That is, the position of the dimming sheet 11 is not easily shifted regardless of the stacking direction during conveying. Therefore, friction of the sealing part 11h can be suppressed.

[0140] Furthermore, the corners of the first protective plate 31, the second protective plate 32, and the multiple third protective plates 33 are centrally fixed by pressing together the plastic strips at the four corners. The positional relationship of the dimming sheets 11 in the adjacent protective bodies 51 is less likely to deviate in the surface direction of the dimming sheets 11. Therefore, friction of the sealing part 11h can be suppressed.

[0141] According to the second embodiment, the following effects can be obtained.

[0142] (2-1) Protect both sides of each dimming sheet 11 from the friction caused by vibration during transport. Therefore, it can suppress damage and breakage of the dimming sheet 11, and suppress the performance degradation of the sealing part 11h caused by the peeling of the sealing part 11h from the dimming sheet 11.

[0143] (2-2) A first protective plate 31, a second protective plate 32, and multiple sheets sandwiched between the two protective plates 31 and 32 constitute a protective body 51. The bundle body 101 may also have multiple stacked protective bodies 51. Among the adjacent protective bodies 51, the first protective plate 31 of one protective body 51 may also be the second protective plate 32 of the other protective body 51. When the first protective plate 31 of one protective body 51 also serves as the second protective plate 32 of the other protective body 51, the number of each protective plate 31 and 32 can be reduced.

[0144] (2-3) The third protective plate 33 can also be thinner than each of the protective plates 31 and 32. The thinner third protective plate 33 compared to the protective plates 31 and 32 reduces the overall thickness of the bundle 101. Therefore, within a single bundle 101, more protective bodies 51 can be bundled while maintaining a relatively thin overall thickness. That is, within a single bundle 101, more dimming sheets 11 can be bundled while maintaining a relatively thin overall thickness.

[0145] (Third Implementation)

[0146] The structure of the bundle 102 for transporting or storing the dimming sheet 11 will be described below. Hereinafter, the structure of the bundle 102 that is different from that of the bundles 100 and 101 will be mainly described, and the descriptions that are repeated with the bundles 100 and 101 will be omitted.

[0147] like Figure 8 As shown, a first protective plate 31, a second protective plate 32, and multiple sheets sandwiched between the two protective plates 31 and 32 constitute a protective body 52. ​​The multiple sheets are a first protective sheet 21, a dimming sheet 11, and a second protective sheet 22. The protective body 52 includes two dimming sheets 11. Each dimming sheet 11 is sandwiched between the first protective sheet 21 and the second protective sheet 22.

[0148] In addition, one dimming sheet 11 can be stacked with other dimming sheets 11 with only one first protective sheet 21 in between, or with only one second protective sheet 22 in between. One dimming sheet 11 can also be stacked with another dimming sheet 11 with two protective sheets 21 and 22 in between.

[0149] A set of protective bodies 52 may have one or more dimming sheets 11.

[0150] Multiple portions of the first protective sheet 21 can be peelably fixed to the first protective plate 31 using adhesive tape 17, or the adhesive tape 17 can be omitted and the sheet can be left unfixed to the first protective plate 31. Multiple portions of the second protective plate 32 can be peelably fixed to the second protective sheet 22 using adhesive tape 17, or the adhesive tape 17 can be omitted and the sheet can be left unfixed to the first protective plate 31.

[0151] The sealing portion 11h of the dimming sheet 11 can be fixed to the first protective sheet 21 by the first easy-peel strip 16a, or the first easy-peel strip 16a can be omitted and it can be left unfixed to the first protective sheet 21. The extension portion 12a of the flexible wiring substrate 12 can be fixed to the first protective sheet 21 by the second easy-peel strip 16b, or the second easy-peel strip 16b can be omitted and it can be left unfixed to the first protective sheet 21.

[0152] like Figure 9 As shown, the protective body 52 is wound with a stretch film such that the second protective plate 32 is pressed against the first protective plate 31. The bundle 102 of the dimming sheet 11 has multiple cushioning members 61. The protective body 52, which has a square plate shape, has four corner portions 55 as corners. Each corner of the protective body 52 has one cushioning member 61. The corner portions 55 of the protective body 52 are also locations on the end face of the protective body 52 that are easily deformed by stress. The cushioning members 61 mitigate the transmission of stress applied from the outside toward the corner portions 55 of the protective body 52.

[0153] The cushioning member 61 has a cubic shape. The cushioning member 61 has a slit 62 at its center in the thickness direction of the protective body 52, into which the corner 55 of the protective body 52 is inserted. The slit 62 is divided in the cushioning member 61 as a planar, plate-like space conforming to the shape of the corner 55 in the protective body 52. ​​The cushioning member 61 can be made of corrugated cardboard or foamed resin.

[0154] like Figure 10 As shown, the bundle 102 of the dimming sheet 11 includes multiple sets of protective bodies 52, buffer components 61, and a bundle box 71. The buffer components 61 and the bundle box 71 constitute the bundle components.

[0155] In the bundle 102, multiple sets of protective bodies 52 and cushioning components 61 are housed within a bundle box 71. The bundle box 71 is preferably made of a lightweight, high-strength, durable, and inexpensive material. The bundle box 71 can also be made of corrugated cardboard. The bundle box 71 can be made of single-layer corrugated cardboard or double-layer corrugated cardboard such as bi-wall (registered trademark). When increased mechanical strength is required for the bundle box 71, the thickness of the double-layer corrugated cardboard is preferably 10 mm or more.

[0156] The packing box 71 can be an A-type corrugated cardboard box with folded wings forming the upper wall, or a B-type corrugated cardboard box consisting of a main body and a lid. Multiple sets of protective bodies 52 are stacked inside the packing box 71 in such a way that the cushioning components 61 of each set of protective bodies 52 contact each other in the vertical direction.

[0157] like Figure 11 As shown, in a set of protective bodies 52, the total thickness of the dimming sheet 11, the first protective sheet 21, and the second protective sheet 22 along the thickness direction DT of the dimming sheet 11 is the sheet thickness T2. The thicknesses of the first protective plate 31 and the second protective plate 32 along the thickness direction DT of the dimming sheet 11 are the plate thicknesses T3.

[0158] The spacing of the slits 62 in the thickness direction DT of the dimming sheet 11 is the slit height T62. The slit height T62 can be equal to, smaller than, or larger than the sum of the sheet thickness T2 and the two plate thicknesses T3 in a set of protective bodies 52. When the slit height T62 is smaller than the sum of the sheet thickness T2 and the two plate thicknesses T3, the positional displacement of the corners of the protective body 52 relative to the slits 62 can be suppressed.

[0159] The larger the size of the dimming sheet 11, the larger the size of the protective body 52 itself will be. The larger the size of the dimming sheet 11, the easier it is for the protective body 52 to bend under its own weight. When the protective body 52, which is bent under its own weight, comes into contact with other protective bodies 52, the bottom surface of the bundle 71, or other structures, stress and impact are easily transmitted to the dimming sheet 11 through this contact. The thickness T61 of the buffer member 61 in the thickness direction DT of the dimming sheet 11 can also be a size that allows the protective body 52 to separate from the bottom surface of the bundle 71 even when the protective body 52 is bent under its own weight. Moreover, the thickness T61 of the buffer member 61 in the thickness direction DT of the dimming sheet 11 determines the spacing G5 between adjacent protective bodies 52. The thickness T61 of the buffer member 61 can also be a size that prevents the protective body 52 from coming into contact with other structures even when the protective body 52 is bent under its own weight. Where the protective body 52 is required to suppress contact with other structures, the thickness T61 of the buffer member 61 is preferably 30 mm or more, and more preferably 40 mm or more.

[0160] The length L2 of the slit 62 in the planar direction DL of the dimming sheet 11 is the length of the protective body 52 supported by the buffer member 61. The larger the length L2 of the slit 62, the larger the length of the protective body 52 supported by the buffer member 61, thereby suppressing the displacement of the protective body 52 relative to the buffer member 61, i.e., the deflection of the protective body 52 caused by its own weight. When it is required that the protective body 52 suppress deflection, the length L2 of the slit 62 is preferably 1 / 20 or more of the length of the protective body 52 in the planar direction DL of the dimming sheet 11, and more preferably 1 / 10 or more.

[0161] [Example]

[0162] The following describes an embodiment that embodies the bundle 102 in the third embodiment described above.

[0163] First, in this embodiment, the first protective plate 31 and the second protective plate 32 are made of corrugated plastic paper. In this embodiment, the first protective sheet 21 and the second protective sheet 22 are laminates of foamed polyethylene sheet (Minaform (registered trademark): manufactured by Sakai Chemical Industry Co., Ltd.) and multiple sheets of backing paper. Next, a dimming sheet 11 is sandwiched between the foamed polyethylene sheet and the multiple sheets of backing paper, and multiple sheets of foamed polyethylene sheet, multiple sheets of backing paper, and two dimming sheets 11 are sandwiched between the two protective plates 31 and 32. Thus, a protective body 52 with a rectangular plate shape, as described in this embodiment, is obtained.

[0164] Next, the cushioning member 61 is formed using corrugated cardboard with a thickness of 10 mm as the constituent material. Then, one cushioning member 61 is installed at each of the four corners 55 of the protective body 52 in the embodiment, and five protective bodies 52 are stacked in a bundling box 71 to obtain the bundling body 102 of the embodiment. That is, the bundling body 102 of the embodiment is obtained by storing 10 dimming sheets 11 in a bundling box 71. In addition, as a reference example, the bundling body 102 is obtained by omitting the cushioning member 61 from the bundling body 102 of the embodiment.

[0165] Additionally, the dimensions of the bundle 71 for accommodating 10 dimming sheets 11, each of the protective plates 31 and 32, each of the protective sheets 21 and 22, and the buffer member 61 are shown below. Regarding the dimensions of the bundle 71 and the buffer member 61, the longitudinal dimension (length DL in the face direction), the transverse dimension (length DL in the other face direction), and the height (length DT in the thickness direction) are expressed as longitudinal dimension × transverse dimension × height. Regarding the dimensions of each of the protective plates 31 and 32 and each of the protective sheets 21 and 22, the longitudinal dimension (length DL in the face direction) and the transverse dimension (length DL in the other face direction) are expressed as longitudinal dimension × transverse dimension.

[0180] The evaluation results of vibration tests conducted using the bundle 102 in the embodiments and reference examples, as well as vibration tests conducted when 2 to 5 bundles 102 are stacked, are presented in [the table / document]. Figure 12 The vibration test was conducted using the method in JIS Z0200:2020 (8.4 Vibration Test Level 2), applying vibration in both the vertical and horizontal directions. Then, based on the orientation of the outer cargo in the bundle 102 and the position of the protective body 52 in the bundle box 71 before the vibration test, it was determined whether the orientation of the outer cargo in the bundle 102 and the position of the protective body 52 had shifted after the vibration test. Additionally, based on the appearance of the dimming sheet 11 before the vibration test, it was determined whether the appearance of the dimming sheet 11 had been damaged. Furthermore, compared to the interior of the bundle box 71 before the vibration test, it was visually determined whether dust had been generated inside the bundle box 71 after the vibration test.

[0181] In addition, Figure 12 In the diagram, levels where no positional deviation was detected in any of the bundles 71 or any of the protective bodies 52 are marked with an "○". Levels where positional deviation was detected only in a portion of the bundles 71 are marked with a "△", and levels where positional deviation was detected in all of the bundles 71 are marked with an "×". Levels where no damage was detected in any of the dimming sheets 11 are marked with an "○", levels where damage was detected in less than half of the dimming sheets 11 are marked with a "△", and levels where damage was detected in more than half of the dimming sheets 11 are marked with an "×". Furthermore, levels where no visually observable dust was detected in any of the bundles 71 are marked with an "○", and levels where visually observable dust was detected in a portion of the bundles 71 are marked with a "△".

[0182] like Figure 12 The determination results show the cargo posture of the outer packaging. It was confirmed that in the reference example without the buffer component 61, the cargo posture showed no positional shift within the bundle 102 across the entire range of 10 to 50 dimming sheets 11, i.e., a load of 4 kg to 20 kg. Furthermore, it was confirmed that in the embodiment, the cargo posture also showed no positional shift within the bundle 102 across the entire range of 10 to 50 dimming sheets 11.

[0183] On the other hand, such as Figure 12 The product deviation results show that the position of the protective body 52 in the reference example shifted significantly as the number of dimming sheets 11 increased from 10 to 50. In contrast, the position of the protective body 52 in the embodiment did not show any shift throughout the entire range of 10 to 50 dimming sheets 11.

[0184] like Figure 12 As shown in the appearance of the judgment results, it was confirmed that the dimming sheet 11 of the reference example was prone to damage as the number of dimming sheets 11 increased from 10 to 50. In contrast, it was confirmed that the dimming sheet 11 of the embodiment did not suffer damage throughout the entire range of 10 to 50 dimming sheets 11.

[0185] like Figure 12 As shown in the appearance of the judgment results, it was confirmed that the dimming sheet 11 of the reference example was prone to damage as the number of dimming sheets 11 increased from 10 to 50. In contrast, it was confirmed that the dimming sheet 11 of the embodiment did not suffer damage throughout the entire range of 10 to 50 dimming sheets 11.

[0186] like Figure 12The dust generation results show that the bundle 102 in the reference example is prone to dust generation as the number of dimming sheets 11 increases from 10 to 50. In contrast, the bundle 102 in the embodiment does not generate dust throughout the entire range of 10 to 50 dimming sheets 11.

[0187] According to the third embodiment described above, the following effects can be obtained.

[0188] (3-1) The cushioning member 61 is positioned at the edge of the protective body 52 such that the corner 55 of the protective body 52 is separated from the inner surface 71W of the bundle 71 in the surface direction DL of the dimming sheet 11. Therefore, the cushioning member 61 can mitigate the stress and impact transmitted from the bundle 71 to the protective body 52. ​​The mitigation of stress and impact transmitted to the protective body 52 protects the quality of the dimming sheet 11, such as the required durability and aesthetics of the corner of the dimming sheet 11. As a result, the protective performance of the dimming sheet 11 in the bundle 102 is improved.

[0189] (3-2) Since the buffer member 61 has a slit 62 for inserting the corner 55 of the protector 52, the corner 55 of the protector 52 is received in the slit 62 of the buffer member 61, and the corner 55 of the protector 52 is covered by the buffer member 61. Therefore, the effectiveness of protection for the corner 55 of the protector 52 and, consequently, the effectiveness of protection for the corner of the dimming sheet 11 is improved.

[0190] (3-3) When the slit height T62 is smaller than the thickness of the protective body 52, the corner of the protective body 52 is less likely to shift relative to the buffer member 61. Therefore, it is possible to suppress friction and deformation of the dimming sheet 11 due to the positional shift of the corner 55 of the protective body 52 relative to the buffer member 61.

[0191] (3-4) The increase in the size of the dimming sheet 11 leads to the increase in the size of the protective body 52 itself. The larger the size of the dimming sheet 11, the easier it is for the protective body 52 to bend under its own weight. When the protective body 52, which is bent under its own weight, comes into contact with a structure other than the protective body 52, stress and impact are easily transmitted to the dimming sheet 11 through this contact. In this regard, the buffer member 61 is arranged at the edge of the protective body 52 in such a way that the protective body 52 is separated from the inner surface 71W of the bundle 71 in the thickness direction DT of the dimming sheet 11. Therefore, the stress and impact transmitted from the bundle 71 to the protective body 52 are mitigated. That is, the stress and impact transmitted from the bundle 71 to the dimming sheet 11 are mitigated. As a result, the quality protection performance of the dimming sheet 11 in the bundle 102 is improved.

[0192] (3-5) The buffer member 61 is positioned at the edge of the protective body 52 in such a way that the protective body 52 is separated from the other protective bodies 52 in the thickness direction DT of the dimming sheet 11. Therefore, the stress and impact transmitted between one protective body 52 and other protective bodies 52 can be mitigated between the two protective bodies 52. That is, the stress and impact transmitted from the other protective bodies 52 to the dimming sheet 11 of one protective body 52 are mitigated. As a result, the protective quality of the dimming sheet 11 in the bundle 102 is further improved.

[0193] [Example of Change]

[0194] Furthermore, the first to third embodiments can be modified and implemented as follows. Additionally, the above embodiments and their modifications can be combined with each other to the extent that they are not technically contradictory.

[0195] The first protective plate 31, the second protective plate 32, and the third protective plate 33 may also have one or more holes in the center. Even if there are one or more holes in the center, the movement of the dimming sheet 11 in the surface direction can be suppressed when pressure is applied by the stretching film 41.

[0196] • Each protective sheet 21, 22 may also be larger than the first protective plate 31, the second protective plate 32, and the third protective plate 33. For example, each protective plate 31, 32, 33 and each protective sheet 21, 22 may be fixed with adhesive tape 17 having adhesive layers on both sides, thereby allowing each protective sheet 21, 22 that is larger than each protective plate 31, 32, 33 to be fixed relative to each protective plate 31, 32, 33.

[0197] ·exist Figure 5 In this configuration, the dimming sheet 11 can also be arranged on the first protective sheet 21 in an up-down configuration. That is, the dimming sheet 11 can be arranged such that the surface of the dimming sheet 11 on the sealing portion 11h side is in contact with the surface of the first protective sheet 21. In this configuration, a portion of the sealing portion 11h is covered by the first protective sheet 21, but the remaining portion is covered by the first easy-peel strip 16a in such a way that no exposed portion is visible. Therefore, this configuration is included in the configuration where "the first easy-peel strip 16a covers the entire sealing portion 11h". That is, the first easy-peel strip 16a covers the entire sealing portion 11h and fixes the dimming sheet 11 to the first protective sheet 21. Moreover, in this configuration, it is preferable that the first easy-peel strip 16a covers the entire outer periphery 13 of the dimming sheet 11 in a manner that follows the shape of the end face in the outer periphery 13 of the dimming sheet 11.

[0198] A scraper can also be used to fix the front end 12c of the extension 12a of the flexible wiring substrate 12 to the second peelable strip 16b of the first protective sheet 21. That is, the flexible wiring substrate 12 can be fixed to the first protective sheet 21 by means of the second peelable strip 16b in a manner that follows the shape of the flexible wiring substrate 12. Since the adhesive strength of the second peelable strip 16b is increased, the positional displacement of the flexible wiring substrate 12 relative to the first protective sheet 21 can be further suppressed.

[0199] • In the second embodiment, the protective bodies 51 in the first embodiment can also be stacked to form the bundle 101. Since the protective bodies 51 constituting the bundle 101 are all identical in composition, after manufacturing a plurality of protective bodies 51 with the same composition, the bundle 101 can be manufactured in a simple step by stacking the plurality of protective bodies 51.

[0200] In the second embodiment, the dimensions of each of the bundled dimming sheets 11 may be different. This can be due to only one dimming sheet 11 having a different size, or all of the dimming sheets 11 having a different size.

[0201] In the third embodiment, the first protective plate 31 may also have a buffering function to protect the dimming sheet 11 on the surface opposite to the dimming sheet 11. In this case, the first protective sheet 21 may be omitted from the bundle 102 of the dimming sheet 11. The second protective plate 32 may also have a buffering function to protect the dimming sheet 11 on the surface opposite to the dimming sheet 11. In this case, the second protective sheet 22 may be omitted from the bundle 102 of the dimming sheet 11.

[0202] • In the third embodiment, the protective body 52 may not be wound by the stretch film 41.

[0203] The buffer member 61 may also be disposed outside the corner of the edge of the protective body 52. ​​For example, the slit 62 of the buffer member 61 may be straight along the long side of the protective body 52, and the buffer member 61 may be disposed on the long side of the protective body 52 such that the slit 62 clamps a portion of the long side of the protective body 52. ​​Alternatively, the slit 62 of the buffer member 61 may be straight along the short side of the protective body 52, and the buffer member 61 may be disposed on the short side of the protective body 52 such that the slit 62 clamps a portion of the short side of the protective body 52.

[0204] Therefore, the buffer member 61 is arranged on each side of the protective body 52 in such a way that the corner 55 of the protective body 52 is separated from the inner surface 71W of the bundle box 71 in the surface direction DL of the dimming sheet 11. In this configuration, the effects based on (3-1) to (3-3) described above can also be obtained. Alternatively, the buffer member 61 is arranged on each side of the protective body 52 in such a way that the protective body 52 is separated from the inner surface 71W of the bundle box 71 in the thickness direction DT of the dimming sheet 11. In this configuration, the effects based on (3-4) and (3-5) described above can also be obtained.

[0205] • The easy-peel strap can be omitted from the bundle of the dimming sheet. In this case, the protective body may include the dimming sheet, a first protective plate that holds the dimming sheet, and a second protective plate, and the bundling component may include a buffer member disposed at the edge of the protective body in a manner that separates the corner of the protective body from the inner surface of the bundle box in the direction of the dimming sheet.

[0206] The corners of the protective body containing the dimming sheet are areas prone to deformation due to stress, even on the end face of the protective body. Regarding this, according to the above configuration, a cushioning member is positioned at the edge of the protective body in a manner that separates the corners of the protective body from the inner surface of the bundle. Therefore, the stress and impact transmitted from the bundle to the protective body are mitigated. That is, the stress and impact transmitted from the bundle to the dimming sheet are mitigated. As a result, whether the sealing part is fixed to the protective sheet using an easy-peel tape or not, the degradation of the dimming sheet quality caused by the stress and impact acting on the protective body from the bundle is suppressed. Furthermore, the protective performance of the dimming sheet within the bundle is improved.

[0207] • The easy-peel strap can be omitted from the bundle of the dimming sheet. In this case, the protective body may include the dimming sheet, a first protective plate that holds the dimming sheet, and a second protective plate. The bundle may also include a buffer member disposed at the edge of the protective body in a manner that separates the protective body from the inner surface of the bundle in the thickness direction of the dimming sheet.

[0208] The increasing size of the dimming sheet also leads to the increasing size of the protective structure itself. The larger the size of the dimming sheet, the more easily the protective structure flexes under its own weight. When such a flexed protective structure comes into contact with a structure outside the protective structure, stress and impact can easily be transmitted to the dimming sheet through this contact.

[0209] Regarding this, the cushioning component is positioned at the edge of the protective body in such a way that the protective body separates from the inner surface of the bundle in the thickness direction of the dimming sheet. Therefore, the stress and impact transmitted from the bundle to the protective body are mitigated. That is, the stress and impact transmitted from the bundle to the dimming sheet are mitigated. As a result, whether the sealing part is fixed to the protective sheet using an easy-peel tape or not, the quality degradation of the dimming sheet caused by the stress and impact acting on the protective body from the bundle can be suppressed. Furthermore, the protective performance of the dimming sheet within the bundle is improved.

[0210] (Fourth Implementation)

[0211] The packaging body of the dimming sheet in the fourth embodiment includes a winding body 35 for winding one dimming sheet 11 onto the cylindrical component 31T.

[0212] [Composition of dimming sheet 11]

[0213] The dimming sheet 11 has a first surface and a second surface opposite to the first surface. The first surface and the second surface extend along the extension direction of the dimming sheet 11, respectively. Figure 13 The planar structure of the dimming sheet 11 is shown as viewed from a viewpoint opposite the first face of the dimming sheet 11.

[0214] like Figure 13 As shown, the dimming sheet 11 may also have a rectangular shape. The dimming sheet 11 may also have a pair of opposing short sides 14 and a pair of opposing long sides 15. The dimming sheet 11 includes a pair of flexible wiring substrates 12. The pair of flexible wiring substrates 12 may also be connected to the outer periphery 13 of the dimming sheet 11 and disposed on one of the short sides 14 of the dimming sheet 11.

[0215] like Figure 14 As shown, the dimming sheet 11 includes a first transparent electrode film 11a, a second transparent electrode film 11d, a dimming layer 11g containing a liquid crystal composition 11m, and a sealing portion 11h. The liquid crystal composition 11m is sealed between the two transparent electrode films 11a and 11d. The dimming layer 11g is sandwiched between the first transparent electrode film 11a and the second transparent electrode film 11d. The sealing portion 11h seals the surrounding portion 13, i.e., the outer peripheral portion, between the first transparent electrode film 11a and the second transparent electrode film 11d.

[0216] The first transparent electrode film 11a includes a first transparent substrate 11b and a first transparent electrode layer 11c. The first transparent substrate 11b supports the first transparent electrode layer 11c. The second transparent electrode film 11d includes a second transparent substrate 11e and a second transparent electrode layer 11f. The second transparent substrate 11e supports the second transparent electrode layer 11f.

[0217] The flexible wiring substrate 12 has an extension 12a extending from the short side 14 of the first transparent electrode film 11a and the second transparent electrode film 11d toward the outer side of the first transparent electrode film 11a and the second transparent electrode film 11d. One of the pair of flexible wiring substrates 12 is electrically connected to the first transparent electrode layer 11c. The other of the pair of flexible wiring substrates 12 is electrically connected to the second transparent electrode layer 11f.

[0218] The dimming layer 11g comprises a transparent polymer layer and a liquid crystal composition. The transparent polymer layer is divided to fill the voids in the liquid crystal composition. The voids in the transparent polymer layer are of a certain size and number that cause visible light entering the dimming layer 11g to scatter due to the refractive index difference between the transparent polymer layer and the liquid crystal composition, thereby making the dimming layer 11g cloudy. The liquid crystal composition fills the voids in the transparent polymer layer.

[0219] [Composition of the winding body 35]

[0220] like Figure 15 As shown, the winding body 35 includes a cylindrical member 31T extending along the axial direction X and a dimming sheet 11. The cylindrical member 31T constitutes a bundling member. The cylindrical member 31T has a through hole 31H extending along the axial direction X and passing through it. Furthermore, the presence or absence of the through hole 31H is not limited as long as the outer periphery of the cylindrical member 31T is cylindrical. Therefore, the shape of the cylindrical member 31T can also be cylindrical. However, since the through hole 31H reduces the weight of the cylindrical member 31T, it is preferable that the cylindrical member 31T has a through hole 31H.

[0221] To prevent damage to the surface of the dimming sheet 11, the tube component 31T is preferably made of a material with a non-hard surface. For example, a paper tube is used for the tube component 31T. A paper tube is a tube or cylinder made of paper and is mainly used as a shaft for winding paper, fiber, film, etc. In the dimming sheet 11, due to its high bending rigidity, a paper tube with a larger diameter is used, for example, a paper tube with a diameter of 10 inches.

[0222] The dimming sheet 11 has a portion, namely the winding start portion 21T, that is in contact with the outer peripheral surface 31b of the cylindrical member 31T and begins to be wound onto the cylindrical member 31T. The winding start portion 21T has one short side 14 of the dimming sheet 11.

[0223] The short side 14 of the winding start portion 21T is fixed to the outer peripheral surface 31b of the cylindrical component 31T using a first easy-peel tape 16a. The short side 14 of the winding start portion 21T is fixed at approximately the center position in the axial direction X of the cylindrical component 31T such that the length direction of the short side 14 is in the same direction as the axial direction X of the cylindrical component 31T. Thus, a central portion for winding the dimming sheet 11 along the circumferential direction Y of the cylindrical component 31T is formed in the cylindrical component 31T, and two cylindrical ends 31a protruding from the dimming sheet 11 on both sides in the axial direction X of the cylindrical component 31T when the dimming sheet 11 is wound on the cylindrical component 31T. That is, the cylindrical component 31T has a central portion for winding the dimming sheet 11 and two cylindrical ends 31a protruding from the dimming sheet 11 wound on both sides in the axial direction X of the cylindrical component 31T.

[0224] The wound body 35 includes a first easy-peel strip 16a. In the winding start portion 21T, five first easy-peel strips 16a are used to fix the short side 14 to the cylindrical component 31T. More specifically, the adhesive surface of the first easy-peel strip 16a is adhered to the outer surface of the dimming sheet 11, and the adhesive surface of the first easy-peel strip 16a is adhered to the outer peripheral surface 31b, thereby fixing the short side 14 to the cylindrical component 31T. On the outer surface of the dimming sheet 11, the portion adhered to the adhesive surface of the first easy-peel strip 16a is the fixed portion 23. The adhesive force per unit area of ​​the first easy-peel strip 16a is the amount of adhesive component remaining on the substrate of the first easy-peel strip 16a upon unpacking, and the amount of adhesive component not easily remaining on the surface of the dimming sheet 11.

[0225] Three first easy-peel strips 16a are adhered along the circumferential direction Y, thereby fixing the central portion of the short side 14 to the outer peripheral surface 31b. The number of first easy-peel strips 16a adhered along the circumferential direction Y in the central portion of the short side 14 can also be varied depending on the length of the short side 14, the width of the first easy-peel strips 16a used, etc.

[0226] A first peelable strip 16a is attached to one end of the short side 14, in the direction between the axial direction X and the circumferential direction Y of the cylindrical member 31T, and in the direction from the corner 14a to the end of the cylindrical member 31T. Thus, the corner 14a of the dimming sheet 11, which is one end of the short side 14, is fixed to the outer peripheral surface 31b.

[0227] The corner portion 14a is included in the fixed portion 23 at the end of the short side 14. The corner portion 14a is composed of the end of the short side 14 and the end of the long side 15. The first peelable strip 16a, which fixes the corner portion 14a of the dimming sheet 11, fixes the end of the short side 14 and the end of the long side 15 to the outer peripheral surface 31b.

[0228] A first peelable strip 16a is attached at the other end of the short side 14, in the direction between the axial direction X and the circumferential direction Y of the cylindrical member 31T, and in the direction from the corner 14a to the other end of the cylindrical member 31T. Thus, the corner 14a of the dimming sheet 11, which is the other end of the short side 14, is fixed to the outer peripheral surface 31b.

[0229] Alternatively, a longer first peelable strip 16a extending along the axial direction X can be adhered along the axial direction X, thereby fixing the short side 14 integrally to the cylindrical component 31T.

[0230] In the winding start section 21T, the first peelable strips 16a that fix the short side 14 are preferably arranged at approximately equal intervals. The short side 14 is efficiently fixed by a small number of first peelable strips 16a.

[0231] In the winding start portion 21T, the corner 14a of the dimming sheet 11 is preferably fixed to the outer peripheral surface 31b using a first easy-peel strip 16a. The first easy-peel strip 16a can protect the corner 14a of the dimming sheet 11, which has relatively low mechanical strength.

[0232] The winding body 35 has two second easy-peeling strips 16b. The winding start portion 21T has a fixed portion 24 on each of the two long sides 15 connected to the short side 14, located away from the short side 14. In the winding start portion 21T, with the inner side surface of the dimming sheet 11 along the outer peripheral surface 31b, the two fixed portions 24 are respectively fixed to the outer peripheral surface 31b of the tube end 31a by the second easy-peeling strips 16b.

[0233] The outer surface of the dimming sheet 11 is adhered to the adhesive surface of the second easy-peel tape 16b. The outer peripheral surface 31b of the cylindrical component 31T is adhered to the adhesive surface of the second easy-peel tape 16b. Thus, the fixing part 24 is fixed to the cylindrical component 31T. On the outer surface of the dimming sheet 11, the portion adhered to the adhesive surface of the second easy-peel tape 16b is the fixing part 24. The adhesive force per unit adhesive area of ​​the second easy-peel tape 16b is the amount of adhesive component of the second easy-peel tape 16b remaining on the substrate of the second easy-peel tape 16b when unpacking, and the amount of adhesive component of the second easy-peel tape 16b not easily remaining on the surface of the dimming sheet 11.

[0234] The portion of the dimming sheet 11 that contacts the outer peripheral surface 31b of the cylindrical member 31T is the first coil of sheet material. The fixing portion 24 is the outer surface of the dimming sheet 11 including a portion of the long side 15, and is part of the first coil of sheet material in the dimming sheet 11 wound around the cylindrical member 31T. On the outer surface of the dimming sheet 11, the first coil of sheet material has two fixing portions 23 and 24 arranged along the circumferential direction Y of the cylindrical member 31T on the two long sides 15 connected to the short side 14. The fixing portions 23 and 24 are fixed to the outer peripheral surface 31b of the cylindrical member 31T using easy-peeling tapes 16a and 16b, respectively. Alternatively, the first coil of sheet material may have two or more fixing portions 23 and 24 arranged along the circumferential direction Y of the cylindrical member 31T on the outer surface of the dimming sheet 11. That is, two or more second peelable strips 16b can be used on one long side 15, so that the sheet portion of the first ring has two or more fixed portions 24 on each of the two long sides 15 connected to the short side 14.

[0235] The point closest to the short side 14 among the long sides 15 included in the fixing part 24 is the fixing start point 24a. The point furthest from the short side 14 among the long sides 15 included in the fixing part 24 is the fixing end point 24b. The dimming sheet 11 is fixed to the end of the cylinder 31a by means of the second easy-peel tape 16b, so that the portion of the long side 15 from the fixing start point 24a to the fixing end point 24b is in contact with the outer peripheral surface 31b of the cylinder component 31T.

[0236] like Figure 16 As shown, the dimming sheet 11 is wound at least one turn in the circumferential direction Y of the cylindrical member 31T. The dimming sheet 11 has a winding end portion 25 that is in contact with the outer surface of the dimming sheet 11 wound on the cylindrical member 31T and ends the winding onto the cylindrical member 31T. The winding end portion 25 has one short side 14 of the dimming sheet 11 and a pair of flexible wiring substrates 12 connected to the short side 14.

[0237] The wound body 35 includes a first easy-peel strip 16a. The short side 14 of the winding end portion 25 is fixed to the outer surface of the dimming sheet 11 wound on the cylindrical member 31T by the first easy-peel strip 16a. When the dimming sheet 11 is finished being wound, the position of the short side 14 in the axial direction X of the winding start portion 21T is the same as the position of the short side 14 in the axial direction X of the winding end portion 25. Furthermore, the length direction of the short side 14 in the winding end portion 25 is the same as the axial direction X of the cylindrical member 31T. In this state, the short side 14 of the winding end portion 25 is fixed to both the dimming sheet 11 and the cylindrical member 31T.

[0238] In the winding end portion 25, five first easy-peel tapes 16a are used to fix the short side 14 to the dimming sheet 11 and the cylindrical component 31T. The adhesive force per unit bonding area of ​​the first easy-peel tape 16a is such that when unpacking, the adhesive component of the first easy-peel tape 16a remains on the substrate of the first easy-peel tape 16a and is not easily left on the outer surface of the dimming sheet 11.

[0239] Three first easy-peel tapes 16a are adhered along the circumferential direction Y, thereby fixing the central portion of the short side 14 to the outer surface of the dimming sheet 11 wound on the cylindrical member 31T. The outer surface of the dimming sheet 11 in the winding end portion 25 is adhered to the adhesive surface of the first easy-peel tapes 16a using the three first easy-peel tapes 16a. The outer surface of the dimming sheet 11 wound on the cylindrical member 31T is adhered to the adhesive surface of the first easy-peel tapes 16a. Thus, the short side 14 is fixed to the outer surface of the dimming sheet 11 using the three first easy-peel tapes 16a. The number of first easy-peel tapes 16a adhered to the central portion of the short side 14 in the circumferential direction Y can also be varied depending on the length of the short side 14, the width of the first easy-peel tapes 16a used, etc.

[0240] A first easy-peel tape 16a is adhered at one end of the short side 14, facing the direction between the axial direction X and the circumferential direction Y of the cylindrical member 31T, and from the corner 14a approaching the end of the cylindrical member 31T. Thus, the first easy-peel tape 16a fixes the corner 14a of the dimming sheet 11, which is one end of the short side 14, to the outer surface of the dimming sheet 11 wound around the cylindrical member 31T, and fixes the corner 14a to the outer peripheral surface 31b. More specifically, the adhesive surface of the first easy-peel tape 16a is adhered to the outer surface of the dimming sheet 11 in the winding end portion 25, and also to the outer surface of the dimming sheet 11 wound around the cylindrical member 31T. Furthermore, the adhesive surface of the first easy-peel tape 16a is adhered to the outer peripheral surface 31b. Thus, by using a first easy-peeling tape 16a, one corner 14a of the short side 14 in the winding end portion 25 is fixed to the outer side surface and outer peripheral surface 31b of the dimming sheet 11 wound on the cylindrical component 31T.

[0241] The corner portion 14a is formed by the end of the short side 14 and the end of the long side 15. The first peelable strip 16a that fixes the corner portion 14a of the dimming sheet 11 fixes the end of the short side 14 and the end of the long side 15 to the outer surface and outer peripheral surface 31b of the dimming sheet 11 wound on the cylindrical component 31T.

[0242] A first easy-peel tape 16a is adhered at the other end of the short side 14, in the direction between the axial direction X and the circumferential direction Y of the cylindrical member 31T, and in the direction from the corner 14a towards the other end of the cylindrical member 31T. Thus, the first easy-peel tape 16a fixes the corner 14a of the dimming sheet 11, which is the other end of the short side 14, to the outer surface of the dimming sheet 11 wound around the cylindrical member 31T, and fixes the corner 14a to the outer peripheral surface 31b. More specifically, the adhesive surface of the first easy-peel tape 16a is adhered to the outer surface of the dimming sheet 11 in the winding end portion 25, and also to the outer surface of the dimming sheet 11 wound around the cylindrical member 31T. Furthermore, the adhesive surface of the first easy-peel tape 16a is adhered to the outer peripheral surface 31b. Thus, by using a first easy-peeling strip 16a, the corner 14a of the other side of the short side 14 in the winding end portion 25 is fixed to the outer side surface and outer peripheral surface 31b of the dimming sheet 11 wound on the cylindrical component 31T.

[0243] Alternatively, a longer first peelable strip 16a extending along the axial direction X can be adhered along the axial direction X. This also allows the short side 14 to be integrally fixed to the cylindrical component 31T.

[0244] In the winding end portion 25, the first peelable strips 16a that secure the short side 14 are preferably arranged at approximately equal intervals. This allows for efficient securing of the short side 14 with a small number of first peelable strips 16a. Furthermore, in the winding end portion 25, the corners 14a of the dimming sheet 11 can also be secured to the outer peripheral surface 31b. This allows the first peelable strips 16a to protect the relatively weak corners 14a of the dimming sheet 11.

[0245] The winding body 35 has a third easy-peel strip 16c. The third easy-peel strip 16c fixes the front end portion 12c of the extension portion 12a of the flexible wiring substrate 12 to the dimming sheet 11 wound on the cylindrical member 31T.

[0246] The front ends 12c of the two flexible wiring substrates 12 can also be fixed to the outer side of the dimming sheet 11 using a longer third easy-peel strip 16c. The base end 12b of the flexible wiring substrate 12 can also be fixed to the outer side of the dimming sheet 11 by another third easy-peel strip 16c. In addition, in this case, the third easy-peel strip 16c that fixes the base end 12b can also overlap and adhere to the first easy-peel strip 16a that fixes the short side 14. The adhesive force per unit bonding area of ​​the third easy-peel strip 16c is the size at which the adhesive component of the third easy-peel strip 16c remains on the substrate of the third easy-peel strip 16c when unpacking, and the adhesive component of the third easy-peel strip 16c does not easily remain on the surface of the flexible wiring substrate 12 and the surface of the dimming sheet 11.

[0247] In the winding end portion 25, the dimming sheet 11 may also be wound onto the cylindrical member 31T at the end of the short side 14 of the flexible wiring substrate 12 arrangement. At this time, the third easy-peel tape 16c may also fix the front end portion 12c of the extension portion 12a of the flexible wiring substrate 12 to the dimming sheet 11 wound onto the cylindrical member 31T. Alternatively, it may be wound onto the cylindrical member 31T starting from the short side 14 of the flexible wiring substrate 12 arrangement and ending at the short side 14 of the other flexible wiring substrate 12 arrangement. That is, the extension portion 12a may also be fixed to at least one of the cylindrical member 31T and the dimming sheet 11 by the third easy-peel tape 16c.

[0248] The flexible wiring substrate 12 is preferably fixed to at least one of the cylindrical member 31T and the dimming sheet 11 via a protective sheet. For example, a foamed sheet or bubble-filled cushioning material can be used in the protective sheet. A foamed sheet, for example, refers to a cushioning material that contains independent air bubbles and is elastic by foaming polyethylene. Bubble-filled cushioning materials, for example, are sheets formed by sealing air within cylindrical protrusions, such as Petit Petit (registered trademark) or Air Cap (registered trademark). Because the outer surface of the cylindrical member 31T or the dimming sheet 11 does not contact the inner surface of the flexible wiring substrate 12 due to the protective sheet 51, damage to the surfaces of the flexible wiring substrate 12 and the dimming sheet 11 can be suppressed. The entire flexible wiring substrate 12 or a portion thereof can also be protected from above by the protective sheet.

[0249] The winding body 35 includes a fourth easy-peel strip 16d. The fourth easy-peel strip 16d is disposed on the outer surface of the dimming sheet 11 to which the winding end portion 25 is fixed. The fourth easy-peel strip 16d is positioned opposite the short side 14 of the winding end portion 25, separated by the center CL of the cylindrical component 31T. The fourth easy-peel strip 16d fixes a portion of the long side 15 to the outer peripheral surface 31b. The adhesive surface of the fourth easy-peel strip 16d is adhered to the outer surface of the dimming sheet 11 to which the winding end portion 25 is fixed. The adhesive surface of the fourth easy-peel strip 16d is adhered to the outer peripheral surface 31b. The two portions of the long side 15 are a portion of the long side 15 on one side and a portion of the long side 15 on the other side along the axial direction X of the dimming sheet 11.

[0250] In the winding end portion 25, two corner portions 14a are fixed to the outer peripheral surface 31b using a first easy-peel tape 16a. This prevents the short side 14 from shifting in the axial direction X. The portion of the dimming sheet 11 opposite the short side 14, separated by the center CL, is fixed to the outer peripheral surface 31b using a fourth easy-peel tape 16d. This prevents the long side 15 from shifting in the axial direction X. Therefore, the dimming sheet 11 as a whole is less likely to shift in the axial direction X during transport.

[0251] [Unwinding state of dimming sheet 11]

[0252] like Figure 17 As shown, during the unpacking operation, when the dimming sheet 11 is unwound from the cylindrical component 31T, the dimming sheet 11, which was originally pressed against the winding start portion 21T from above, leaves the winding start portion 21T. At this time, the winding start portion 21T is exposed. In the winding start portion 21T, the dimming sheet 11 is fixed to the outer peripheral surface 31b at multiple locations by fixing portions 23 and at two locations by fixing portions 24, with the inner side of the dimming sheet 11 along the outer peripheral surface 31b of the cylindrical component 31T. Figure 17 This is a schematic diagram showing the bending shape of the long side 15 of the dimming sheet 11 when it has been unwound.

[0253] On the inner side of the dimming sheet 11, except for a portion of the short side 14 and a portion of the long side 15 included in the fixing part 23, and a portion of the long side 15 included in the fixing part 24, the portion of the dimming sheet 11 is not fixed to the outer peripheral surface 31b. While slightly deforming the shape of the easy-peel strips 16a and 16b, the portion of the dimming sheet 11 other than a portion of the short side 14 and a portion of the long side 15 included in the fixing part 23, and a portion of the long side 15 included in the fixing part 24, floats up from the outer peripheral surface 31b.

[0254] The central angle formed by the short side 14 and the fixed end point 24b relative to the center CL of the cylindrical component 31T is the first angle θ1. The central angle formed by the short side 14 and the fixed start point 24a relative to the center CL of the cylindrical component 31T is the second angle θ2.

[0255] like Figure 18 As shown, assume the distance between the shorter side 14 and the fixed end point 24b is... Figure 17 If the state shown increases, the distance between the portion where the inner side of the dimming sheet 11 is fixed along the outer peripheral surface 31b by the easy-peeling strips 16a and 16b increases. If the first angle θ1 increases, the angle at which the inner side of the dimming sheet 11 is fixed along the outer peripheral surface 31b by the easy-peeling strips 16a and 16b increases.

[0256] like Figure 19 As shown, assume the distance between the shorter side 14 and the fixed starting point 24a is... Figure 17 If the state shown decreases, the length of the portion of the long side 15 that is not fixed by either of the easy-peeling strips 16a and 16b becomes shorter. If the second angle θ2 decreases, the angle of the portion of the inner surface of the dimming sheet 11 that is not fixed to the outer peripheral surface 31b between the easy-peeling strips 16a and 16b becomes smaller.

[0257] If the distance between the short side 14 and the fixed end point 24b becomes shorter, the distance between the portions of the two first peelable strips 16a that fix the inner side of the dimming sheet 11 along the outer peripheral surface 31b also becomes shorter. If the first angle θ1 becomes smaller, the angle at which the two first peelable strips 16a fix the inner side of the dimming sheet 11 along the outer peripheral surface 31b also becomes smaller.

[0258] [Composition of Bundle 100]

[0259] like Figure 20 As shown, a winding body 35, comprising a cylindrical member 31T and a dimming sheet 11, winds a protective sheet 51 around the dimming sheet 11. The ends of the wound protective sheet 51 are secured to the outer surface of the protective sheet 51 using easy-peel tape. Thus, the friction between the outer surface of the nth turn of the dimming sheet 11 and the inner surface of the (n+1)th turn of the dimming sheet 11 when pressed together suppresses any misalignment between them. The length of the protective sheet 51 along the X-axis is slightly longer than the length of the short side 14 of the dimming sheet 11. Therefore, the protective sheet 51 protects the entire outer surface of the dimming sheet 11. Furthermore, both ends of the protective sheet 51 along the X-axis are secured to the outer peripheral surface 31b of the cylindrical member 31T using easy-peel tape. The friction between the surface of the protective sheet 51 and the outer surface of the dimming sheet 11 suppresses any misalignment of the protective sheet 51 relative to the dimming sheet 11. Furthermore, the protective sheet 51 is preferably wound into at least two layers. By winding the protective sheet 51 into at least two layers, the surfaces of the protective sheet 51 overlap each other, thus the friction between the surfaces of the protective sheet 51 can be used to suppress the loosening of the protective sheet 51.

[0260] The bundle 100 includes a first fixing member 41M that is embedded in one end tube 31a and a second fixing member 42M that is embedded in the other end tube 31a. The first fixing member 41M and the second fixing member 42M constitute a bundle component and a position limiting component. The first fixing member 41M and the second fixing member 42M are generally square-shaped boards, such as corrugated cardboard. Alternatively, corrugated paper made of plastic can also be used.

[0261] The first fixing member 41M and the second fixing member 42M have a first hole 45 approximately at the center. The first fixing member 41M and the second fixing member 42M have the same shape. One cylindrical end 31a is inserted into the first hole 45 of the first fixing member 41M. The other cylindrical end 31a is inserted into the first hole 45 of the second fixing member 42M. The first fixing member 41M and the second fixing member 42M are inserted around the first hole 45 on the side where the cylindrical end 31a is inserted, at a position where they meet the end of the protective sheet 51. Thus, the first fixing member 41M and the second fixing member 42M position the dimming sheet 11 relative to the cylindrical member 31T in the axial direction X.

[0262] Alternatively, the protective sheet 51 can be omitted from the bundle of the dimming sheet 11. Alternatively, the length of the protective sheet 51 along the X-axis can be slightly shorter than the length of the short side 14 of the dimming sheet 11, with the long side 15 of the dimming sheet 11 protruding from the protective sheet 51. The first fixing member 41M and the second fixing member 42M can also directly position the dimming sheet 11 relative to the cylindrical member 31T along the X-axis. However, to protect the long side 15 of the dimming sheet 11, it is preferable that the protective sheet 51 protects the entire outer surface of the dimming sheet 11.

[0263] The distance between the first fixing member 41M and the long side 15 opposite to the first fixing member 41M, and the distance between the second fixing member 42M and the long side 15 opposite to the second fixing member 42M, are preferably 10 mm or more. The impact buffering effect of the protective sheet 51 located between each fixing member 41M, 42M and the long side 15 mitigates the impact transmitted from each fixing member 41M, 42M to the dimming sheet 11.

[0264] Each fixing component 41M and 42M has two second holes 46. The two second holes 46 are arranged approximately symmetrically with respect to the plane passing through the center of the first hole 45. Each fixing component 41M and 42M is inserted into the end of the cylinder 31a with the two second holes 46 facing upwards. At this time, the first hole 45 is positioned at a height where the outer peripheral surface of the protective sheet 51 does not contact the floor surface or the working surface.

[0265] When the cylindrical component 31T is embedded with the fixing components 41M and 42M, it is preferable that the short sides 14 of the flexible wiring substrate 12 face downwards. The short sides 14 of the flexible wiring substrate 12 have electrode portions of the dimming sheet 11. The electrode portions are relatively weak in impact resistance within the dimming sheet 11. Unpacking is performed from the top of the winding body 35. The downward-facing configuration of the short sides 14 of the flexible wiring substrate 12 protects the electrode portions during unpacking.

[0266] The first operator inserts the fingers of their right hand into one of the upper second holes 46 in the first fixing member 41M, and the fingers of their left hand into the other second hole 46. Then, the second operator inserts the fingers of their right hand into one of the upper second holes 46 in the second fixing member 42M, and the fingers of their left hand into the other second hole 46. Thus, the two operators can lift the dimming sheet 11 wound with the protective sheet 51 without directly contacting it. That is, the operators can move the wound dimming sheet 11 without changing the state of the dimming sheet 11 wound on the cylindrical member 31T.

[0267] like Figure 21 As shown, the bundle 100 of the dimming sheet 11 includes a bundle box 61T for packing the wound body 35. The bundle box 61T constitutes a bundling component. The preferred material for the bundle box 61T is lightweight, has high mechanical strength, high durability, and is inexpensive. The bundle box 61T can also be a corrugated cardboard box. The wound body is lifted by the two second holes 46 of the first fixing member 41M and the two second holes 46 of the second fixing member 42M and is placed in the bundle box 61T.

[0268] like Figure 22 As shown, the bundle body 100 includes a third fixing member 43 that fixes one end 31c of the cylindrical member 31T along the axial X direction relative to the bundle box 61T. Furthermore, the bundle body 100 includes a fourth fixing member 44 that fixes the other end 31d of the cylindrical member 31T along the axial X direction relative to the bundle box 61T. The third fixing member 43 and the fourth fixing member 44 are generally square-shaped boards, such as corrugated cardboard. Alternatively, corrugated plastic paper can also be used.

[0269] The axial X-axis dimension of the inner side of the bundle box 61T is shorter than the sum of the thicknesses of the third fixing member 43 and the fourth fixing member 44 compared to the axial X-axis dimension of the cylindrical member 31T. Therefore, the dimming sheet 11 wound on the cylindrical member 31T can be easily placed in the bundle box 61T. After the dimming sheet 11 wound on the cylindrical member 31T is placed in the bundle box 61T, the third fixing member 43 and the fourth fixing member 44 are placed. The third fixing member 43 is inserted between the inner wall 61a of the bundle box 61T and one end 31c, and the fourth fixing member 44 is inserted between the inner wall 61b of the bundle box 61T and the other end 31d. Thus, the axial X-axis position of the dimming sheet 11 wound on the cylindrical member 31T is fixed inside the bundle box 61T.

[0270] The dimming sheet 11 wound around the cylindrical component 31T is supported by the first fixing member 41M and the second fixing member 42M, thus forming a gap Δ between the outer side of the protective sheet 51 wound around the dimming sheet 11 and the inner surface of the bundle box 61T, including the inner bottom 61c. The first fixing member 41M and the second fixing member 42M are position limiting members that allow the dimming sheet 11 wound around the cylindrical component 31T to separate from the inner surface of the bundle box 61T, located between the respective outer peripheral surfaces 31b of the cylindrical end 31a on both sides of the axial direction X and the inner surface of the bundle box 61T. In addition, the inner surface of the bundle box 61T, including the inner bottom 61c, consists of four inner surfaces located in a direction orthogonal to the axial direction X when the bundle box 61T is closed. Furthermore, the value of the gap Δ between the four inner surfaces can be different for each of them.

[0271] [Manufacturing method of bundle 100]

[0272] The manufacturing method of the bundle 100 in the fourth embodiment will be described.

[0273] To manufacture the bundle 100, follow the steps below.

[0274] (a) Unfold the bundled dimming sheet 11 flat so that the side with the product label is facing up on the worktable. Place a cylindrical component 31T with a length in the X-axis that is at least 50 mm longer than the short side 14 of the dimming sheet 11 and a diameter of 10 inches next to the dimming sheet 11.

[0275] (b) As a fixation of the winding start part 21T, two corner parts 14a in the short side 14 and multiple parts in the center of the short side 14 are fixed to the outer peripheral surface 31b of the cylindrical part 31T using an easy-peeling strip 16a with a width of 50mm.

[0276] (c) While the inner side of the dimming sheet 11 is aligned with the outer peripheral surface 31b of the cylindrical component 31T, the two long sides 15 connected to the short side 14 are fixed to the outer peripheral surface 31b of the cylindrical component 31T using an easy-peel strip 16b with a width of 50 mm. The fixing position is such that the distance between the short side 14 and the fixing starting point 24a is more than 50 mm and less than 100 mm.

[0277] (d) When a flexible wiring substrate 12 is present and connected to the short side 14 of the winding start portion 21T of the dimming sheet 11, the base end portion 12b and the front end portion 12c of the flexible wiring substrate 12 are fixed to the outer peripheral surface 31b of the cylindrical member 31T via a protective sheet using an easy-peel tape 16c. Furthermore, the entire short side 14, including the electrode portion of the flexible wiring substrate 12, i.e., the base end portion 12b, is protected from above by the protective sheet.

[0278] (e) The dimming sheet 11 is wound around the outer peripheral surface 31b of the cylindrical component 31T at least once. The two corners 14a of the short side 14 in the winding end portion 25 of the dimming sheet 11 and multiple portions of the central portion of the short side 14 are fixed to the outer surface of the dimming sheet 11 wound around the cylindrical component 31T and the outer peripheral surface 31b of the cylindrical component 31T by easy-peel tape 16a.

[0279] (f) Relative to the center CL of the cylindrical component 31T, the two long side portions 15 located on the opposite side of the short side 14 at 180° in the winding end portion 25 are fixed to the outer peripheral surface 31b of the cylindrical component 31T by a fourth easy-peeling strip 16d with a width of 50 mm.

[0280] (g) When a flexible wiring substrate 12 is present and connected to the short side 14 in the winding end portion 25 of the dimming sheet 11, the base end portion 12b and the front end portion 12c of the flexible wiring substrate 12 are fixed to the outer surface of the dimming sheet 11 via a protective sheet using an easy-peeling tape 16c.

[0281] (h) A protective sheet 51 is wound onto the dimming sheet 11 to which the winding end portion 25 is fixed. Then, the end portion of the wound protective sheet 51 is fixed to the outer surface of the wound protective sheet 51. Then, both ends of the protective sheet 51 in the axial direction X are fixed to the outer peripheral surface 31b of the cylindrical member 31T. Then, a label sticker indicating that it is a bundled product is affixed to the protective sheet 51.

[0282] (i) With the second hole 46 of the first fixing member 41M and the second fixing member 42M positioned above, the first fixing member 41M is inserted into one end of the cylinder 31a, and the second fixing member 42M is inserted into the other end of the cylinder 31a. The first fixing member 41M and the second fixing member 42M are inserted until they are positioned around the first hole 45 to press against the edge of the protective sheet 51.

[0283] (j) The dimming sheet 11 wound on the cylindrical component 31T is lifted by the two second holes 46 of the first fixing component 41M and the two second holes 46 of the second fixing component 42M and is placed in the packaging box 61T.

[0284] (k) A third fixing member 43 is inserted between the inner wall 61a of the bundle box 61T and one end 31c, and a fourth fixing member 44 is inserted between the inner wall 61b of the bundle box 61T and the other end 31d, thereby fixing the position of the dimming sheet 11 in the axial direction X.

[0285] (l) Close the lid of the bundling box 61T and seal it with bundling straps. Finally, affix a label sticker showing the bundled product to the outer surface of the bundling box 61T, thus completing the bundling operation for manufacturing the bundle body 100 in this embodiment.

[0286] return Figure 17 During the unpacking process, when the dimming sheet 11 is unwound from the cylindrical component 31T, if the dimming sheet 11, which was originally pressed down from above against the winding start portion 21T, leaves the winding start portion 21T, the winding start portion 21T will be exposed. The fixed portion 23, including the short side 14, is fixed to the outer peripheral surface 31b within the winding start portion 21T. The fixed portion 24, which does not include the short side 14, is also fixed to the outer peripheral surface 31b within the winding start portion 21T.

[0287] The adhesive force Fa of the first easy-peel tape 16a is pressed against the outer peripheral surface 31b by one free end of the fixing part 23. The adhesive force Fb of the second easy-peel tape 16b is pressed against the outer peripheral surface 31b by the other free end of the fixing part 24. The dimming sheet 11 utilizes its restoring force to form a beam-like deflection curve that causes the two free ends to float from the outer peripheral surface 31b. The restoring force of the dimming sheet 11 is the force by which the curved dimming sheet 11 attempts to restore its planar shape.

[0288] The beam flexural curve of the dimming sheet 11 is a cubic curve. The outer peripheral surface 31b of the cylindrical component 31T is a cylindrical surface. The arc that is part of the cylindrical surface is approximately a quadratic curve. The slope of the cubic curve near the origin of the cubic curve passing through the origin of the XY coordinate system is smaller than the slope of the quadratic curve near the origin of the quadratic curve passing through the origin of the XY coordinate system. The radius of curvature near the origin of the cubic curve passing through the origin of the XY coordinate system is larger than the radius of curvature near the origin of the quadratic curve passing through the origin of the XY coordinate system. Near the free end of the dimming sheet 11, the radius of curvature of the dimming sheet 11 is larger than the radius of curvature of the outer peripheral surface 31b of the cylindrical component 31T. The radius of curvature between the two free ends of the dimming sheet 11 is larger than the radius of curvature of the outer peripheral surface 31b. The bending force Fc of the dimming sheet 11 slightly deforms the shape of the easy-peeling strips 16a and 16b, while causing the portion between the fixed part 23 and the fixed part 24 to float from the outer peripheral surface 31b.

[0289] The dimming sheet 11 exerts forces Fd1a, Fd1b, Fd2a, and Fd2b on the easy-peel strips 16a and 16b in the direction normal to the outer peripheral surface 31b, thereby lifting the easy-peel strips 16a and 16b from the outer peripheral surface 31b. These forces Fd1a, Fd1b, Fd2a, and Fd2b are generated by the flexural force Fc of the dimming sheet 11.

[0290] The force Fd1a that peels off the easy-peel strips 16a and 16b at the short side 14 is approximately equal to the force Fd1b that peels off the easy-peel strips 16a and 16b at the portion of the fixed part 23 opposite to the short side 14. The force Fd2b that peels off the easy-peel strips 16a and 16b at the fixed end point 24b is approximately equal to the force Fd2a that peels off the easy-peel strips 16a and 16b at the portion of the fixed part 23 opposite to the fixed start point 24a. The adhesive forces Fa and Fb of the easy-peel strips 16a and 16b resist the peeling forces Fd1a, Fd1b, Fd2a, and Fd2b. The central angle formed by the two free ends relative to the center CL of the cylindrical component 31T is preferably approximately 60°. With a central angle of approximately 60°, the winding start part 21T is stably fixed to the outer peripheral surface 31b.

[0291] like Figure 18 As shown, it is assumed that the position of the fixed part 24 is far from the position of the fixed part 23. That is, in comparison... Figure 17 The fixed part 24 is positioned further away from the center of the beam. Therefore, the force Fd2b lifted at the fixing end point 24b increases. Similarly, the force Fd1a lifted at the short side 14 increases.

[0292] If the first angle θ1 increases, the flexural force Fc increases by the amount by which the first angle θ1 increases, and forces Fd1a and Fd2b also increase. Furthermore, with... Figure 17 Compared to the state shown, the dimming sheet 11 rises significantly from the outer peripheral surface 31b.

[0293] Furthermore, the flexural force Fc causes the central portion of the dimming sheet 11 in the axial X direction to also float from the outer peripheral surface 31b. However, the central portion of the dimming sheet 11 in the axial X direction has a gentle curved shape, which reduces the floating of the dimming sheet 11 compared to the long side 15. On the other hand, the long side 15 of the dimming sheet 11 is restricted from floating by the second peelable strip 16b. Therefore, a relatively large upward buoyancy force acts on the dimming sheet 11 at the corner 14a formed by the long side 15 and the short side 14.

[0294] Thus, the dimming sheet 11 is lifted at the fixed end point 24b and deformed in a way that maximizes the lifting of the corner 14a.

[0295] The mechanical strength of corner 14a is lower than that of other parts. When the first angle θ1 is large, a larger restoring force acts on the dimming sheet 11 as the first angle θ1 increases. The larger restoring force easily damages corner 14a. When the center angle is approximately 60°, peeling of the easy-peeling strips 16a and 16b and damage to corner 14a can be suppressed.

[0296] like Figure 19As shown, it is assumed that the position of the fixed part 24 is close to the position of the fixed part 23. That is, in comparison... Figure 17 The fixing part 24 shown is positioned near the center of the beam. Therefore, the force Fd2a lifted at the fixing start point 24a increases. Similarly, the force Fd1b lifted at the fixing part 23 increases.

[0297] If the second angle θ2 decreases, the flexural force Fc decreases, but the forces Fd2a and Fd1b lifted from the center of the beam increase. Furthermore, compared to... Figure 17 Compared to the state shown, the dimming sheet 11 rises significantly from the outer peripheral surface 31b.

[0298] Here, the flexural force Fc also causes the central portion of the dimming sheet 11 in the axial X direction to float from the outer peripheral surface 31b. However, the central portion of the dimming sheet 11 in the axial X direction has a gentle curved shape, which reduces the floating of the dimming sheet 11 compared to the long side 15. On the other hand, a portion of the long side 15 of the dimming sheet 11 is restricted from floating by the second peelable strip 16b. Therefore, a relatively large upward buoyancy force acts on the dimming sheet 11 at the corner 14a formed by the long side 15 and the short side 14.

[0299] Thus, the dimming sheet 11 is lifted at the fixed starting point 24a and deformed in a way that raises the corner 14a to the maximum extent.

[0300] The mechanical strength of corner 14a is lower than that of other parts. When the second angle θ2 is smaller, corresponding to a larger first angle θ1, corner 14a is prone to breakage. When the central angle is approximately 60°, the peeling of the easily peelable strips 16a and 16b and the breakage of corner 14a can be suppressed.

[0301] When the second angle θ2 is small, the first angle θ1 is prone to becoming too small. When the first angle θ1 is too small, the fixing of the dimming sheet 11 in the winding start section 21T and the cylindrical component 31T is unstable. Therefore, a first angle θ1 larger than the specified value makes the fixing of the winding start section 21T and the cylindrical component 31T more stable.

[0302] like Figure 16 As shown, in the winding end portion 25, the short side 14 is fixed to the outer peripheral surface 31b by a first easy-peel tape 16a. In the long side 15, the portion opposite the short side 14 across the center CL is fixed to the outer peripheral surface 31b by a second easy-peel tape 16b.

[0303] like Figure 20As shown, the protective sheet 51 is wound around the dimming sheet 11 in the circumferential direction Y. The end of the protective sheet 51 is secured to its outer surface using an easy-peel tape. The inner surface of the (n+1)th turn of the dimming sheet 11 is pressed against the outer surface of the nth turn of the dimming sheet 11 by the winding of the protective sheet 51. The positional displacement of the outer surface of the nth turn of the dimming sheet 11 relative to the inner surface of the (n+1)th turn of the dimming sheet 11 is suppressed by the winding of the protective sheet 51.

[0304] The first fixing component 41M and the second fixing component 42M position the two ends of the protective sheet 51 along the axial X direction of the cylindrical component 31T. The first fixing component 41M and the second fixing component 42M position the two ends of the dimming sheet 11 along the axial X direction of the cylindrical component 31T.

[0305] like Figure 21 As shown, the third fixing component 43 and the fourth fixing component 44 position the cylindrical component 31T on the bundle box 61T. Thus, the entire dimming sheet 11 is positioned on the bundle box 61T.

[0306] [Confirmation results of stability in the winding start section 21T]

[0307] By varying the values ​​of the first angle θ1 and the second angle θ2, a winding body 35 is formed by winding the dimming sheet 11 onto the cylindrical component 31T. The following shows the evaluation results of the stability in the winding start portion 21T when the winding body 35 is unwound.

[0308] When the first angle θ1 is greater than 69°, during the unpacking operation, when unwinding the dimming sheet 11 from the cylindrical component 31T, it is confirmed that the easy-peeling strips 16a and 16b are peeling off, or the corner 14a is broken. When the second angle θ2 is less than 23°, during the unpacking operation, when unwinding the dimming sheet 11 from the cylindrical component 31T, it is confirmed that the easy-peeling strips 16a and 16b are peeling off, or the corner 14a is broken. When the first angle θ1 is less than 46°, during the unpacking operation, when unwinding the dimming sheet 11 from the cylindrical component 31T, it is confirmed that the easy-peeling strips 16a and 16b are peeling off, or the corner 14a is broken. Furthermore, "broken" includes irreversible bending, damage, cracking, and other deformations that reduce the quality of the dimming sheet 11.

[0309] Thus, when the first angle θ1 is greater than 69°, during the unpacking operation, the corner 14a is easily damaged due to the restoring force when unwinding the dimming sheet 11 from the tube component 31T. When the second angle θ2 is less than 23°, during the unpacking operation, the corner 14a is easily damaged due to the restoring force when unwinding the dimming sheet 11 from the tube component 31T. When the first angle θ1 is less than 46°, during the unpacking operation, the corner 14a is easily damaged due to the fixed offset of the dimming sheet 11 when unwinding the dimming sheet 11 from the tube component 31T.

[0310] When the magnitude of the first angle θ1 is 69° or less, the breakage of the corner 14a can be suppressed. When the magnitude of the second angle θ2 is 23° or more, the breakage of the corner 14a can be suppressed. When the magnitude of the first angle θ1 is 46° or more, the breakage of the corner 14a can be suppressed.

[0311] Furthermore, in the confirmation of the above evaluation, a paper tube with a diameter of 10 inches was used in the tube component 31T. Masking tape with a width of 50 mm was used in the easy-peel strips 16a and 16b. To suppress damage to the corner 14a, the distance between the short side 14 and the fixing start point 24a was 50 mm or more and 100 mm or less, and the distance between the short side 14 and the fixing end point 24b was 100 mm or more and 150 mm or less. The magnitude of the first angle θ1 was 46° or more and 69° or less, and the magnitude of the second angle θ2 was 23°.

[0312] According to the fourth embodiment, the following effects can be obtained.

[0313] (4-1) The winding start portion 21T includes: one short side 14 of the dimming sheet 11; and a fixed portion 24 located away from the short side 14 in each of the two long sides 15 connected to the short side 14. The short side 14 is fixed to the outer peripheral surface 31b of the cylindrical member 31T by a first peelable tape 16a, and the two fixed portions 24 are respectively fixed to the outer peripheral surface 31b of the cylindrical end 31a by a second peelable tape 16b. Therefore, when the dimming sheet 11 is unwound from the cylindrical member 31T, the load caused by the force of the winding start portion 21T lifting off the outer peripheral surface 31b of the cylindrical member 31T is distributed. Therefore, when the dimming sheet 11 is unwound from the cylindrical member 31T, the corner portion 14a of the dimming sheet 11 can be prevented from breaking due to the force of the winding start portion 21T lifting off the outer peripheral surface 31b of the cylindrical member 31T.

[0314] (4-2) When the size of the first angle θ1 is less than 69°, the breakage of the corner 14a is suppressed.

[0315] (4-3) When the first angle θ1 is 46° or more, the winding start part 21T is fixed and stable.

[0316] (4-4) When the second angle θ2 is greater than 23°, the breakage of the corner 14a is suppressed.

[0317] (4-5) The extension 12a is fixed by the third easy-peel tape 16c and is not easily offset relative to the cylindrical component 31T or the dimming sheet 11. Therefore, the stress applied to the joint between the first transparent electrode film 11a and the flexible wiring substrate 12 can be suppressed.

[0318] (4-6) The first fixing member 41M and the second fixing member 42M position the dimming sheet 11 on the cylindrical member 31T in the axial direction X. Therefore, even in the portion of the dimming sheet 11 that is not fixed to the outer peripheral surface 31b of the cylindrical member 31T, the dimming sheet 11 is not easily moved in the axial direction X.

[0319] (4-7) The third fixing component 43 and the fourth fixing component 44 position the cylindrical component 31T in the axial direction X to the bundle box 61T. Therefore, the dimming sheet 11 is not easily moved in the axial direction X relative to the bundle box 61T.

[0320] Furthermore, the fourth embodiment can be implemented with modifications as follows. This embodiment and the following modifications can be combined with each other within the scope of technical inconsistency.

[0321] Alternatively, after overlapping the protective sheet on the outer surface of the dimming sheet 11, the dimming sheet 11 and the protective sheet are wound onto the cylindrical component 31T while still overlapping. The protective sheet prevents the outer surface of the nth turn of the dimming sheet 11 from contacting the inner surface of the (n+1)th turn, thus suppressing friction between the surfaces of the dimming sheets 11.

[0322] • Alternatively, a second dimming sheet 11 can be further wound and bundled from the dimming sheet 11 wound on the cylindrical member 31T. In this case, it is preferable to wind the second dimming sheet 11 onto the protective sheet 51 wound on the dimming sheet 11 wound on the cylindrical member 31T.

[0323] As described above, when bundling multiple dimming sheets 11 within a single bundle 61T, to prevent the flexible wiring substrates 12 in each dimming sheet 11 from overlapping in the X-axis direction, the dimming sheets 11 can be wound with their positions staggered in the X-axis direction. This prevents instability in the winding state of the multiple dimming sheets 11 due to overlapping positions of the flexible wiring substrates 12 in the X-axis direction.

[0324] The dimming sheet 11 can also replace the flexible wiring substrate 12 and have leads connected to the first transparent electrode layer 11c and leads connected to the second transparent electrode layer 11f. The leads can also have an extension 12a extending from the short side 14 of the dimming sheet 11 toward the outside of the first transparent electrode film 11a or the second transparent electrode film 11d. The extension 12a can also be fixed to at least one of the cylindrical member 31T and the dimming sheet 11 using a third easy-peel tape 16c. Preferably, the leads are fixed to at least one of the cylindrical member 31T and the dimming sheet 11 via a protective sheet. With the protective sheet 51, the outer surface of the cylindrical member 31T or the dimming sheet 11 does not contact the leads, thus suppressing damage to the surface of the dimming sheet 11. Furthermore, the entirety or a portion of the leads can also be protected from the leads by the protective sheet.

[0325] When the sheet portion of the first ring has two or more fixed portions 24 on each of the two long sides 15 connected to the short side 14 by using two or more second peelable strips 16b on one long side 15, the spacing between the second peelable strips 16b is preferably approximately 60°. More specifically, the central angle formed by the fixing starting point 24a of the second peelable strip 16b closest to the short side 14 and the fixing starting point 24a of the second peelable strip 16b next closest to the short side 14 with respect to the center CL of the cylindrical component 31T is preferably approximately 60°.

[0326] The dimming sheet 11 may also have a QR code marked by laser. The QR code may embed various manufacturing information of the dimming sheet 11, such as the manufacturing date, batch number, manufacturing location, type of manufacturing equipment, and model number. The QR code can be located at the edge or corner of the dimming sheet 11. Alternatively, the QR code may be configured such that the portion containing the QR code in the transparent electrode layers 11c and 11f has a different conductivity than the surrounding portion, thus allowing for visual identification. Alternatively, the QR code may be configured such that the portion containing the QR code in the dimming layer 11g has a different refractive index than the surrounding portion, thus allowing for visual identification.

[0327] • The protective sheet 51 may also consist entirely of aluminum foil covering the outer surface of the dimming sheet 11. The protective sheet 51 may be just aluminum foil, or it may be a multi-layered structure of a buffer material such as a foamed sheet or bubble buffer material and aluminum foil. The aluminum foil may be disposed on the opposite side of the dimming sheet 11 relative to the buffer material, or it may be disposed on the same side as the dimming sheet 11 relative to the buffer material.

[0328] When the protective sheet 51 has aluminum foil, it is possible to prevent damage to the dimming sheet 11 and to suppress the moisture absorption of the dimming sheet 11.

[0329] • The winding body 35 may also include a desiccant. When the protective sheet 51 is provided with aluminum foil, the desiccant may be disposed on the outer side of the aluminum foil, or between the aluminum foil and the end 31a of the cylindrical member 31T, or fixed to the cylindrical member 31T by surrounding the end edge of the aluminum foil.

[0330] When the winding body 35 contains a desiccant, the moisture absorption of the dimming sheet 11 can be further suppressed. At this time, if the desiccant configuration is required to improve moisture absorption, the desiccant can also be configured to cover at least the long side 15 of the dimming sheet 11 in the entire circumference of the winding body 35.

[0331] [Packing box 61T]

[0332] The corrugated cardboard constituting the bundle 61T can be single-layer corrugated cardboard or double-layer corrugated cardboard such as bi-wall (registered trademark). When the bundle 61T requires increased mechanical strength, the thickness of the double-layer corrugated cardboard is preferably 10mm or more.

[0333] • When the bundle box 61T is required to increase its mechanical strength, the bottom surface of the bundle box 61T may also have multiple beams. The multiple beams are arranged along the axial direction X and extend along the width direction of the bundle box 61T. When the bundle box 61T has multiple beams on its bottom surface, deformation and deterioration of the bottom surface caused by the contact between the bottom surface of the bundle box 61T and the floor surface can be suppressed.

[0334] The packing box 61T may also have a cubic shape and a peripheral wall that rises from the bottom wall of the packing box 61T. The peripheral wall of the packing box 61T may also have a pair of long walls extending along the axial direction X and a pair of short walls extending along the width direction of the packing box 61T. The long walls of the packing box 61T may also be joined to the short walls of the packing box 61T by means of flaps.

[0335] • The 61T packing box can be an A-type corrugated cardboard box with folded wings forming the upper wall, or a B-type corrugated cardboard box consisting of a body and a lid.

[0336] ·like Figure 23 As shown, when manufacturing the bundle body 100, the cylindrical component 31T with the dimming sheet 11 wound around it may not be the bundle box 61T assembled from the blank 71L, but rather the blank 71L before it is assembled into the bundle box 61T. The blank 71L before it is assembled into the bundle box 61T has a plate shape. The blank 71L includes a bottom wall 74 with a rectangular plate shape, short walls 72 and 73 connected to a pair of short sides of the bottom wall 74, long walls 75 connected to a pair of long sides of the bottom wall 74, and a pair of flaps 71F connected to the short walls 72 and 73.

[0337] When manufacturing the bundle 100, firstly, for the cylindrical component 31T wound with the dimming sheet 11, a crane arm 77 extending along the axial direction X of the cylindrical component 31T is inserted into the cylinder of the cylindrical component 31T. The cylindrical component 31T with the arm 77 inserted is lifted by the crane and placed on the bottom wall 74 of the semi-finished product 71L. In addition, when the bundle 100 is equipped with a first fixing member 41M and a second fixing member 42M, the arm 77 is inserted into the cylinder of the cylindrical component 31T with the first fixing member 41M embedded in one end 31a and the second fixing member 42M embedded in the other end 31a.

[0338] like Figure 24 As shown, if the cylindrical component 31T is positioned on the bottom wall 74 of the semi-finished product 71L, the boom 77 of the crane is pulled out from inside the cylindrical component 31T. Next, the semi-finished product 71L is bent so that the short walls 72, 73 and the long wall 75 are upright relative to the bottom wall 74. Then, the flaps 71F of the short walls 72, 73 are bent to cover a portion of the outer surface of the long wall 75 and secured to the long wall 75 using straps 71T. Furthermore, if the bundle box 61T is equipped with a third fixing member 43 and a fourth fixing member 44, one short wall 72 is bent relative to the bottom wall 74 to clamp the third fixing member 43 between it and the cylindrical end 31a of the cylindrical component 31T. Additionally, other short walls 73 are bent relative to the bottom wall 74 to clamp the fourth fixing member 44 between them. Thus, the dimming sheet 11 wound on the cylindrical component 31T is housed in a cubic housing with an opening opposite to the bottom wall. Then, the cover 81 is installed in the housing such that it blocks the opening of the housing with a cubic cover 81 facing downwards.

[0339] Based on the above modification examples, the following effects can be achieved.

[0340] (4-8) When the dimming sheet 11, which is circumferentially wound along the cylindrical member 31T, bends relative to the virtual straight line extending along the axial direction X, creases are easily formed in the dimming sheet 11. Regarding this, since the cylindrical member 31T is transported with the boom 77 of the crane inserted into the cylinder of the cylindrical member 31T, the cylindrical member 31T itself easily maintains its shape extending along the axial direction X. As a result, bending of the suspended cylindrical member 31T and the dimming sheet 11 relative to the virtual straight line extending along the axial direction X due to their own weight can be suppressed. Moreover, as long as the shape of the cylindrical member 31T is easily maintained in a configuration extending along the axial direction X by the insertion of the boom 77, the formation of creases in the dimming sheet 11 can be suppressed.

[0341] (4-9) The suspended cylindrical component 31T is placed in the semi-finished product 71L before being assembled into the bundle box 61T. Therefore, compared to the case where the dimming sheet 11 is placed in the assembled bundle box 61T, contact between the dimming sheet 11 and the bundle box 61T can be suppressed. As a result, damage to the dimming sheet 11 due to contact with the bundle box 61T can be suppressed.

[0342] (4-10) After the cylindrical component 31T is placed on the semi-finished product 71L, it is assembled from the semi-finished product 71L into a bundle box 61T. Therefore, even if the arrangement of the cylindrical component 31T uses the boom 77 of a crane to transport it from the cylindrical end 31a of the cylindrical component 31T, the dimming sheet 11 can be accommodated in the bundle box 61T.

[0343] (4-11) Since the flaps 71F of the bundle 61T are located on the outer side of the long wall 75, a step with a thickness equivalent to that of the flaps 71F is formed on the outer surface of the bundle 61T but not on the inner surface. Therefore, the dimming sheet 11 is housed in the bundle 61T with its outer surface facing the flat surface of the inner surface of the long wall 75. As a result, contact between the outer surface of the dimming sheet 11 and the step of the flaps 71F can be suppressed, thereby suppressing damage to the dimming sheet 11 caused by contact with the step.

[0344] In the bundle 100 having a first fixing member 41M embedded in one end of the tube 31a and a second fixing member 42M embedded in the other end of the tube 31a, at least one of the first easy-peel strip 16a and the second easy-peel strip 16b may be omitted. Additionally, at least one of the third easy-peel strip 16c and the fourth easy-peel strip 16d may also be omitted. Even with these configurations, the effects based on (4-6) and (4-7) described above can be obtained.

[0345] The flexible wiring substrate 12 may also have an extension 12a extending from the dimming sheet 11 in the axial direction X. Even with this configuration, the effects based on (4-1) to (4-11) described above can be obtained.

[0346] Furthermore, the base end portion 12b of the flexible wiring substrate 12 connected to the dimming sheet 11 can also be arranged along the axial direction X. Moreover, the extension portion 12a of the flexible wiring substrate 12 can also be arranged to extend along the circumferential direction of the cylindrical member 31T. In this case, a portion of the extension portion 12a of the flexible wiring substrate 12 can also be fixed to at least one of the dimming sheet 11 and the cylindrical member 31T using a third easy-peel tape 16c. The base end portion 12b of the flexible wiring substrate 12 can also be connected to the first transparent electrode layer 11c or the second transparent electrode layer 11f via an anisotropic conductive agent or the like.

[0347] According to this configuration, compared to the case where the extension 12a of the flexible wiring substrate 12 is configured to extend along the axial direction X of the cylindrical member 31T, the shape of the flexible wiring substrate 12 easily follows the outer peripheral surface 31b of the cylindrical member 31T, and the flexible wiring substrate 12 is less likely to float. Furthermore, corresponding to the fact that the shape of the flexible wiring substrate 12 easily follows the outer peripheral surface 31b of the cylindrical member 31T, stress such as peeling the flexible wiring substrate 12 from the first transparent electrode layer 11c can be suppressed from acting on the connection portion between the first transparent electrode layer 11c and the flexible wiring substrate 12. Additionally, stress such as peeling the flexible wiring substrate 12 from the second transparent electrode layer 11f can be suppressed from acting on the connection portion between the second transparent electrode layer 11f and the flexible wiring substrate 12. As a result, peeling of the flexible wiring substrate 12 from the first transparent electrode layer 11c due to the bundling of the dimming sheet 11 can be suppressed, and the increase in resistance between the flexible wiring substrate 12 and the first transparent electrode layer 11c can be suppressed. In addition, it can suppress the flexible wiring substrate 12 from the second transparent electrode layer 11f due to the bundling of the dimming sheet 11, and can suppress the increase in resistance between the flexible wiring substrate 12 and the second transparent electrode layer 11f.

[0348] At this time, an easy-peel strip may also be provided to fix the connection portion of the flexible wiring substrate 12 and the dimming sheet 11 to at least one of the cylindrical member 31T and the dimming sheet. Alternatively, at least one of the first easy-peel strip 16a, the second easy-peel strip 16b, and the third easy-peel strip 16c may be omitted. Additionally, the fourth easy-peel strip 16d may be omitted. Furthermore, at least one of the third fixing member 43 and the fourth fixing member 44 may be omitted.

[0349] The technical ideas derived from the first to fourth embodiments described above are described below.

[0350] [Postscript 1]

[0351] A bundle for a dimming sheet, comprising a dimming sheet and a bundle component supporting the dimming sheet, characterized in that,

[0352] The dimming sheet includes: a first transparent electrode film; a second transparent electrode film; a sealing portion that seals the gap between the first transparent electrode film and the second transparent electrode film at the outer periphery of the dimming sheet; and a liquid crystal composition sealed into the gap surrounded by the sealing portion.

[0353] The bundle body includes an easy-peel strap that covers the sealing portion and secures the sealing portion to the bundle component.

[0354] [Postscript 2]

[0355] According to Appendix 1, the packaging of the dimming sheet...

[0356] The easy-peel strip covers the entire outer periphery of the dimming sheet along its end face.

[0357] According to the configuration in Appendix 2, it is less likely that a gap will form between the easy-peel strip and the end face of the outer periphery. Because the easy-peel strip easily contacts the end face of the outer periphery, the adhesive strength of the easy-peel strip relative to the dimming sheet is increased. Therefore, the position of the sealing portion of the dimming sheet is less likely to shift relative to the bundling component.

[0358] [Postscript 3]

[0359] According to Appendix 1, the packaging of the dimming sheet...

[0360] The bundling component includes:

[0361] First protection plate;

[0362] The second protective plate, wherein the entire dimming sheet is sandwiched between the first protective plate and the second protective plate;

[0363] A first protective sheet, sandwiched between the dimming sheet and the first protective plate, is in overall contact with one surface of the dimming sheet; and

[0364] The second protective sheet is sandwiched between the dimming sheet and the second protective plate, and is in overall contact with the other side of the dimming sheet.

[0365] The easy-peel strip covers the entire sealing portion and secures the dimming sheet to the first protective sheet.

[0366] The bundle also includes a stretch film that is wound to press the second protective plate against the first protective plate.

[0367] According to the configuration in Appendix 3, the position of the first protective sheet is not easily shifted relative to the first protective plate in the planar direction. The position of the second protective sheet is not easily shifted relative to the second protective plate in the planar direction. Therefore, when the dimming sheet is conveyed with its surface perpendicular to the protective plate, the dimming sheet, which is subjected to vibration during conveying, is positioned by the protective sheet and is not easily shifted off the protective plate and falls off.

[0368] [Postscript 4]

[0369] According to Appendix 1, the packaging of the dimming sheet...

[0370] A protective body comprises a first protective plate, a second protective plate, and a dimming sheet sandwiched between the first protective plate and the second protective plate.

[0371] The bundle body has:

[0372] A bundled box, containing the protective body; and

[0373] A cushioning component is positioned at the edge of the protective body in such a way that the corners of the protective body separate from the inner surface of the bundle box in the surface direction of the dimming sheet.

[0374] The buffer component has slits into which the corners of the protective body can be inserted.

[0375] In the thickness direction of the dimming sheet, the slit is thicker than the protective body.

[0376] According to the configuration in Appendix 4, the corner of the protective body is less likely to shift relative to the buffer component. Therefore, friction and deformation of the dimming sheet caused by the shift of the corner of the protective body relative to the buffer component can be suppressed.

[0377] [Postscript 5]

[0378] According to Appendix 1, the packaging of the dimming sheet...

[0379] A protective body comprises a first protective plate, a second protective plate, and a dimming sheet sandwiched between the first protective plate and the second protective plate.

[0380] The bundle also has the following features:

[0381] A bundled box, containing the protective object;

[0382] Multiple sets of the aforementioned protective bodies stacked together; and

[0383] A cushioning element is positioned at the edge of the protective body in such a way that it separates the protective body from the inner surface of the bundle in the thickness direction of the dimming sheet.
