Description

[Technical field]

[0001] The present disclosure relates to a package of a light controlling sheet. [Background technology]

[0002] An example of the above-mentioned package includes a laminate and a pair of protective plates sandwiching the laminate. The laminate includes a plate-shaped substrate and a protective film disposed on at least one of a pair of main surfaces of the plate-shaped substrate (see, for example, Patent Document 1). A light-controlling sheet, which is an example of a plate-shaped substrate, includes a first transparent electrode film, a second transparent electrode film, and a light-controlling layer sandwiched between the first transparent electrode film and the second transparent electrode film. The light-controlling layer includes a liquid crystal composition. The peripheral portion of the light-controlling sheet includes a sealing portion that seals the gap between the first transparent electrode film and the second transparent electrode film in the light-controlling layer.

[0003] [Patent Document 1] JP 2020-93839 A Summary of the Invention [Problem to be solved by the invention]

[0004] The corners of the protector in which the light-adjusting sheet is sandwiched are the areas of the protector's edge that are most susceptible to deformation due to stress. Furthermore, increasing the size of the light-adjusting sheet also leads to an increase in the size of the protector itself. The larger the light-adjusting sheet, the more likely the protector itself is to bend under its own weight. When a protector that bends under its own weight comes into contact with a structure other than the protector, stress and impact are likely to be transmitted to the light-adjusting sheet through that contact.

[0005] Whether the sealing portion of the light-adjusting sheet is fixed to the protective sheet with easily peelable tape or not, it is desirable to suppress deterioration in the quality of the light-adjusting sheet due to stress and impact acting on the protective body from the packaging box. [Means for solving the problem]

[0006] In a package for a light-adjusting sheet that solves the above problems, the light-adjusting sheet comprises 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 light-adjusting sheet, and a liquid crystal composition that is sealed in the gap surrounded by the sealing portion, and the package comprises a protective body and a packaging box that houses the protective body, and the protective body comprises the light-adjusting sheet, a first protective plate that sandwiches the entire light-adjusting sheet, and a second protective plate, and the package comprises a cushioning member that is arranged on the edge of the protective body so as to separate the corners of the protective body from the inner surface of the packaging box in the surface direction of the light-adjusting sheet.

[0011] (First embodiment) Below, the configuration of the light adjusting sheet which is the packaged item will be described, followed by the configuration of the protector that protects one light adjusting sheet, and the configuration of the package for the light adjusting sheet, and each of the configurations will be described in order.

[0012] [Composition of light control sheet] The light controlling sheet 11 has a first surface and a second surface opposite to the first surface. The first surface and the second surface each extend along the direction in which the light controlling sheet 11 extends. FIG. 1 shows the planar structure of the light controlling sheet 11 as viewed from a viewpoint opposite to the first surface of the light controlling sheet 11.

[0013] As shown in FIG. 1, the outer shape of the light controlling sheet 11 has a rectangular shape. The light controlling sheet 11 includes a pair of flexible wiring boards 12. The pair of flexible wiring boards 12 are connected to an outer periphery 13 of the light controlling sheet 11 and are aligned along one side of the light controlling sheet 11. The side on which the flexible wiring boards 12 are arranged may be a long side of the light controlling sheet 11 or a short side of the light controlling sheet 11. The side on which the flexible wiring boards 12 are arranged may be set based on the arrangement of a drive circuit in the light controlling sheet 11, etc.

[0014] As shown in Fig. 2, the light control sheet 11 includes a first transparent electrode film 11a, a second transparent electrode film 11d, a light control layer 11g, and a sealing portion 11h. The light control layer 11g is sealed in 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 with the outer periphery 13 of the light control sheet 11. The light control layer 11g is sealed in the gap surrounded by the sealing portion 11h.

[0015] The light-adjusting layer 11g comprises a transparent polymer layer and a liquid crystal composition. The transparent polymer layer defines a gap for filling with the liquid crystal composition. The gaps defined by the transparent polymer layer have a size and quantity that scatters visible light entering the light-adjusting layer 11g due to the difference in refractive index between the transparent polymer layer and the liquid crystal composition, thereby making the light-adjusting layer 11g cloudy. The liquid crystal composition is filled in the gaps in the transparent polymer layer.

[0016] The liquid crystal composition is held in one of the following types: polymer dispersion type, polymer network type, and capsule type. The polymer dispersion type has a large number of isolated voids in a transparent polymer layer, and holds the liquid crystal composition in the voids dispersed in the polymer layer. The polymer network type has a transparent polymer network having a three-dimensional mesh shape, and holds the liquid crystal composition in the mesh-like voids that are interconnected. The polymer network is an example of a transparent polymer layer. The capsule type holds the liquid crystal composition having a capsule shape in the transparent polymer layer. The liquid crystal composition may contain, in addition to the liquid crystal compound, a monomer for forming a transparent polymer layer, a dichroic dye, a plasticizer, and the like. The light control layer 11g may contain a spacer for maintaining the thickness of the light control layer 11g within a certain range.

[0017] 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 includes a first surface of the light control 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 includes a second surface of the light control sheet 11.

[0018] The first transparent electrode film 11a may include an alignment layer between the first transparent electrode layer 11c and the light control layer 11g, or may include a hard coat layer on the side of the first transparent substrate 11b opposite to the first transparent electrode layer 11c. The second transparent electrode film 11d may include an alignment layer between the second transparent electrode layer 11f and the light control layer 11g, or may include a hard coat layer on the side of the second transparent substrate 11e opposite to the second transparent electrode layer 11f.

[0019] The flexible wiring board 12 includes an extension portion 12a extending toward the outside of the first transparent electrode film 11a and the second transparent electrode film 11d. One of the pair of flexible wiring boards 12 is electrically connected to the first transparent electrode layer 11c, and the other of the pair of flexible wiring boards 12 is electrically connected to the second transparent electrode layer 11f. This allows the pair of flexible wiring boards 12 to apply a driving voltage to the light control layer 11g sandwiched between the first transparent electrode film 11a and the second transparent electrode film 11d.

[0020] For example, in a normal-type light-adjusting sheet 11, when no electric field is formed between the transparent electrode layers 11c and 11f, the long axis direction of the liquid crystal compounds is irregularly aligned so that light incident on the light-adjusting sheet 11 is scattered, thereby making the light-adjusting sheet 11 opaque. When an electric field is formed between the transparent electrode layers 11c and 11f, the long axis direction of the liquid crystal compounds follows the electric field so that light incident on the light-adjusting sheet 11 is transmitted, thereby making the light-adjusting sheet 11 transparent.

[0021] For example, in the reverse-type light-adjusting sheet 11, when no electric field is formed between the transparent electrode layers 11c and 11f, the long axis direction of the liquid crystal compounds aligns following the regulating force of the alignment layer, thereby making the light-adjusting sheet 11 transparent. When an electric field is formed in the transparent electrode layers 11c and 11f, the long axis direction of the liquid crystal compounds follows the electric field so that light incident on the light-adjusting sheet 11 is scattered, thereby making the light-adjusting sheet 11 opaque.

[0022] In this way, the light controlling sheet 11 reversibly switches from transparent to opaque. The first surface of the light controlling sheet 11 may be attached to a transparent body such as a window glass, a partition, or a showcase. The first surface of the light controlling sheet 11 may be attached to a first transparent plate, and the second surface of the light controlling sheet 11 may be attached to a second transparent plate, thereby sandwiching the light controlling sheet 11 between the two transparent plates. Alternatively, the light controlling sheet 11 may be used as a projection screen without being attached to a transparent body.

[0023] [Protection body composition] As shown in FIG. 3, the protective body 51 includes a light controlling sheet 11, a first protective sheet 21, and a second protective sheet 22.

[0024] The size of the first protective sheet 21 is larger than that of the light-adjusting sheet 11. When viewed from a viewpoint opposite the first surface of the light-adjusting sheet 11, the outer periphery of the first protective sheet 21 is disposed so as to protrude from the light-adjusting sheet 11. The size of the second protective sheet 22 is larger than that of the light-adjusting sheet 11. When viewed from a viewpoint opposite the second surface of the light-adjusting sheet 11, the outer periphery of the second protective sheet 22 is disposed so as to protrude from the light-adjusting sheet 11.

[0025] The protective sheets 21 and 22 cooperate to cover the entire light-adjusting sheet 11. The protective sheets 21 and 22 sandwich the entire light-adjusting sheet 11. The first protective sheet 21 contacts the first surface of the light-adjusting sheet 11 to protect the entire first surface of the light-adjusting sheet 11. The second protective sheet 22 contacts the entire second surface of the light-adjusting sheet 11 to protect the entire second surface of the light-adjusting sheet 11. The protective sheets 21 and 22 may each have an adhesive layer that is easily peelable from the light-adjusting sheet 11, or may not have adhesive properties to the light-adjusting sheet 11.

[0026] The protective body 51 includes a first protective plate 31 and a second protective plate 32 . The first protective plate 31 is larger than the light controlling sheet 11. When viewed from a viewpoint facing the first surface of the light controlling sheet 11, the outer periphery of the first protective plate 31 is disposed so as to protrude from the light controlling sheet 11. The outer periphery of the first protective plate 31 may be disposed so as to protrude from the first protective sheet 21, or may be disposed so as not to protrude from the first protective sheet 21. The first protective plate 31 contacts the surface of the first protective sheet 21 opposite to the surface that contacts the light controlling sheet 11.

[0027] The second protective plate 32 is larger than the light controlling sheet 11. When viewed from a viewpoint facing the second surface of the light controlling sheet 11, the outer periphery of the second protective plate 32 is disposed so as to protrude from the light controlling sheet 11. The outer periphery of the second protective plate 32 may be disposed so as to protrude from the second protective sheet 22, or may be disposed so as not to protrude from the second protective sheet 22. The second protective plate 32 contacts the surface of the second protective sheet 22 opposite to the surface that contacts the light controlling sheet 11.

[0028] The first protective plate 31 and the second protective plate 32 cooperate to cover the entire light controlling sheet 11. The first protective plate 31 and the second protective plate 32 sandwich the entire light controlling sheet 11. The first protective plate 31 contacts the first protective sheet 21 to protect the entire first surface of the light controlling sheet 11. The second protective plate 32 contacts the second protective sheet 22 to protect the entire second surface of the light controlling sheet 11.

[0029] In this manner, the first protective plate 31, the first protective sheet 21, the light controlling sheet 11, the second protective sheet 22, and the second protective plate 32 are laminated in this order to form a protective body 51 that protects the entire light controlling sheet 11. The first protective plate 31, the second protective plate 32, and a plurality of sheets sandwiched between the first protective plate 31 and the second protective plate 32 form one protective body 51. The plurality of sheets are the first protective sheet 21, the light controlling sheet 11, and the second protective sheet 22.

[0030] When it is required to improve the suppression of rubbing against the surface of the light controlling sheet 11, or when it is required to improve the suppression of localized pressure against the surface of the light controlling sheet 11, it is preferable that the protective sheets 21 and 22 each have elasticity. One example of the protective sheets 21 and 22 is a foam sheet. The foam sheet is a sheet containing independent air bubbles, and is a cushioning material having elasticity.

[0031] When the protective body 51 is required to be lightweight and have high strength, it is preferable that the protective plates 31 and 32 are both lightweight and strong. One example of the protective plates 31 and 32 is a corrugated board having a Bi-Wall (registered trademark) structure and a thickness of 10 mm or more. The Bi-Wall (registered trademark) structure is a corrugated board structure reinforced by gluing two sheets of corrugated board together. The protective plates 31 and 32 may be corrugated board made of plastic.

[0032] The protective plates 31 and 32 may have a rectangular shape. The protective plates 31 and 32 having a rectangular shape can be easily handled during packaging and transportation. The corners of the outer periphery of the protective plates 31 and 32 may be rounded or chamfered at 45 degrees.

[0033] As shown in Fig. 4, a plurality of locations of the first protective sheet 21 are removably fixed to the first protective plate 31 by adhesive tape 17. Fig. 4 shows an example in which the size of the first protective plate 31 and the size of the first protective sheet 21 are the same. A plurality of locations on the outer periphery of the first protective plate 31 are fixed to one side of the outer periphery of the first protective sheet 21 by adhesive tape 17. The adhesive tape 17 is easily removably. This prevents the position of the first protective sheet 21 from shifting relative to the position of the first protective plate 31.

[0034] The surface of the first protective plate 31 facing the first protective sheet 21 at the outer periphery and the surface of the first protective sheet 21 facing the first protective plate 31 at the outer periphery may be fixed by an adhesive tape having an adhesive layer on both sides. The surface of the first protective plate 31 and the surface of the first protective sheet 21 may be fixed by an adhesive tape having an adhesive layer on both sides, inside the outer periphery of the first protective plate 31 and inside the outer periphery of the first protective sheet 21. In this case, the position where the first protective sheet 21 is fixed to the first protective plate 31 is preferably outside the light controlling sheet 11. This can prevent the position of the light controlling sheet 11 from shifting relative to the position of the first protective plate 31.

[0035] The outer periphery of first protective plate 31 may protrude from the outer periphery of first protective sheet 21. In this case, a plurality of locations on the outer periphery of first protective sheet 21 may be fixed to the surface of first protective plate 31 by adhesive tape 17 having an adhesive layer on one side.

[0036] When the first protective plate 31 has a rectangular shape, the first protective sheet 21 may be fixed to one side of the first protective plate 31 at two or more locations of the first protective sheet 21. The number of locations at which the first protective sheet 21 is fixed to the first protective plate 31 may be changed as appropriate depending on the size of the first protective plate 31. For example, the larger the size of the first protective plate 31, the greater the number of locations at which the first protective sheet 21 is fixed to the first protective plate 31 may be.

[0037] A plurality of locations of second protective plate 32 are releasably fixed to second protective sheet 22 by adhesive tape 17. Fig. 4 shows an example in which second protective plate 32 and second protective sheet 22 are the same size. A plurality of locations on the outer periphery of second protective plate 32 are fixed to one side of the outer periphery of second protective sheet 22 by adhesive tape 17. This prevents the position of second protective sheet 22 from shifting relative to the position of second protective plate 32.

[0038] The surface of the second protective plate 32 facing the second protective sheet 22 at the outer periphery and the surface of the second protective sheet 22 facing the second protective plate 32 at the outer periphery may be fixed by an adhesive tape having an adhesive layer on both sides. In addition, the surface of the second protective plate 32 and the surface of the second protective sheet 22 may be fixed by an adhesive tape having an adhesive layer on both sides, inside the outer periphery of the second protective plate 32 and inside the outer periphery of the second protective sheet 22. In this case, the position where the second protective sheet 22 is fixed to the second protective plate 32 is preferably outside the light controlling sheet 11. This can suppress the position of the light controlling sheet 11 from being shifted relative to the position of the second protective plate 32.

[0039] The outer periphery of second protective plate 32 may extend beyond the outer periphery of second protective sheet 22. In this case, a plurality of locations on the outer periphery of second protective sheet 22 may be fixed to the surface of first protective plate 31 by adhesive tape 17 having an adhesive layer on one side.

[0040] When the second protective plate 32 has a rectangular shape, the second protective sheet 22 may be fixed to one side of the second protective plate 32 at two or more locations of the second protective sheet 22. The number of locations at which the second protective sheet 22 is fixed to the second protective plate 32 may be changed as appropriate depending on the size of the second protective plate 32. For example, the larger the size of the second protective plate 32, the greater the number of locations at which the second protective sheet 22 is fixed to the second protective plate 32 may be.

[0041] The protective body 51 includes a first easily peelable tape 16a. The first easily peelable tape 16a covers the entire sealing portion 11h and fixes the light-adjusting sheet 11 to the first protective sheet 21. The first easily peelable tape 16a covers the entire outer periphery 13 of the light-adjusting sheet 11. Each side of the light-adjusting sheet 11 may be fixed to the first protective sheet 21 by a separate first easily peelable tape 16a, or may be fixed to the first protective sheet 21 by one first easily peelable tape 16a. The first easily peelable tape 16a is set to have a weak adhesive force per unit adhesive area so that the adhesive component of the first easily peelable tape 16a is unlikely to remain on the surface of the light-adjusting sheet 11 when the protective body 51 is unpacked.

[0042] Of the first easily peelable tapes 16a on the four sides, the first easily peelable tape 16a on one side fixes the base end portion 12b of the extending portion 12a of the flexible wiring board 12 to the first protective sheet 21 at 11a. The protective body 51 includes a second easily peelable tape 16b. The second easily peelable tape 16b fixes the tip 12c of the extension 12a of the flexible wiring board 12 to the first protective sheet 21. The tip 12c of each flexible wiring board 12 may be fixed to the first protective sheet 21 by separate second easily peelable tapes 16b, or may be fixed to the first protective sheet 21 by one long second easily peelable tape 16b. The adhesive strength per unit adhesive area of ​​the second easily peelable tape 16b is set to be weak so that the adhesive component of the second easily peelable tape 16b is unlikely to remain on the surface of the flexible wiring board 12 when the protective body 51 is unpacked.

[0043] The base end 12b of the flexible wiring board 12 may be fixed to the first protective sheet 21 by a second easily peelable tape 16b that is different from the second easily peelable tape 16b that is fixed to the tip end 12c of the extending portion 12a of the flexible wiring board 12.

[0044] As shown in FIG. 5, the end face of the outer peripheral portion 13 of the light control sheet 11 includes the end face of the sealing portion 11h. The adhesive surface of the first easily peelable tape 16a is adhered to the adherend surface, which is the end face of the sealing portion 11h, and the adherend surface, which is the end face of the first transparent electrode film 11a. The adhesive surface of the first easily peelable tape 16a is also adhered to the adherend surface, which is the surface of the first protective sheet 21. The adhesion of the first easily peelable tape 16a may be performed using a tool such as a squeegee. The squeegee is made of plastic or rubber. The adhesion of the first easily peelable tape 16a is performed by pressing the first easily peelable tape 16a against the end face of the light control sheet 11 to push out and remove air that has accumulated between the adhesive surface and the adherend surface.

[0045] The air that accumulates between the adhesive surface and the surface to be adhered reduces the adhesive area by the amount of the air, and also reduces the adhesive strength between the adhesive surface and the surface to be adhered. The air that accumulates between the adhesive surface and the surface to be adhered is pushed out by the squeegee, so that the adhesive area of ​​the first easily peelable tape 16a can be increased. This increases the adhesive strength between the sealing portion 11h and the first easily peelable tape 16a, the adhesive strength between the first transparent electrode film 11a and the first easily peelable tape 16a, and the adhesive strength between the first protective sheet 21 and the first easily peelable tape 16a. Furthermore, the adhesive surface of the first easily peelable tape 16a can be brought into close contact with the corner portion 18 formed by the end face of the first transparent electrode film 11a and the surface of the first protective sheet 21 by the squeegee.

[0046] The four first easily peelable tapes 16a cover the entire outer periphery 13 of the light adjusting sheet 11. The first easily peelable tapes 16a cover the entire outer periphery 13 of the light adjusting sheet 11 so as to follow the end face shape of the outer periphery 13 of the light adjusting sheet 11. In this way, the above-mentioned fixing method that increases the adhesive area of ​​the first easily peelable tapes 16a suppresses the position of the light adjusting sheet 11 from shifting relative to the first protective sheet 21. Even if the first easily peelable tapes 16a have a weak adhesive strength per unit adhesive area, the adhesive strength can be increased by increasing the adhesive area, thereby fixing the light adjusting sheet 11 to the first protective sheet 21.

[0047] It is preferable that the first easily peelable tape 16a is a wide easily peelable tape in order to increase the adhesion area to the first protective sheet 21. This allows the adhesion area between the first protective sheet 21 and the first easily peelable tape 16a to be increased. For example, a masking tape with a width of 30 mm is used. However, even if a wide easily peelable tape is used, the adhesion area between the sealing portion 11h and the first easily peelable tape 16a does not increase. Therefore, even when a wide easily peelable tape is used, the first easily peelable tape 16a covers the entire outer periphery 13 of the light adjusting sheet 11 so as to follow the end face shape at the outer periphery 13 of the light adjusting sheet 11.

[0048] In the protective body 51, the first protective plate 31 and the second protective plate 32 are preferably fixed by an adhesive tape 17. For example, it is preferable that the adhesive tape 17 is used at least at one location per side, so that the outer periphery of the first protective plate 31 and the outer periphery of the second protective plate 32 are fixed at four sides. With this configuration, the protective body 51 can be handled as a single unit, and rubbing between the surface of the second protective sheet 22 and the surface of the light control sheet 11 can be suppressed.

[0049] [Package composition] As shown in Fig. 6, the packaging body 100 includes a protective body 51. In the protective body 51, the stretch film 41 is wound around the first protective plate 31 so as to press the second protective plate 32 against the first protective plate 31. The protective body 51 is fixed by wrapping the stretch film 41, for example, two or more times in each of the vertical direction and the horizontal direction perpendicular to the vertical direction. By wrapping the stretch film 41 two or more times, the inner stretch film 41 comes into contact with the outer stretch film 41, and loosening of the stretch film 41 can be suppressed.

[0050] It is preferable that the protective plates 31, 32 are deformable in the thickness direction when the stretch film 41 is wrapped around them. By deforming the protective plates 31, 32 in the thickness direction, the surface shapes of the protective plates 31, 32 follow the surface shape of the light-adjusting sheet 11. Therefore, it is possible to suppress deformation of the sandwiched light-adjusting sheet 11 in the thickness direction, and to suppress the position of the light-adjusting sheet 11 from moving in the surface direction relative to the protective plates 31, 32.

[0051] The corners of the rectangular package 100 are the most vulnerable to impact among the end faces of the package 100. Therefore, it is preferable that the four corners of the package 100 are fixed by pressure bonding after vinyl tape is attached to them. When an impact is applied to the corners of the package 100 during transportation, the light control sheet 11 can be prevented from being deformed by the impact. Furthermore, by pressure bonding the vinyl tape at the four corners, the positions of the first protective plate 31 and the second protective plate 32 can be fixed more firmly.

[0052] It is preferable that the entire packaging body 100 is covered with bubble cushioning material at the outermost periphery. The bubble cushioning material is a sheet formed by trapping air in cylindrical protrusions, such as Bubble Wrap (registered trademark) and Air Cap (registered trademark). The bubble cushioning material can cushion the impact on the light control sheet 11 from the surroundings during transportation. It is preferable that the entire packaging body 100 is covered with two layers of bubble cushioning material.

[0053] [Manufacturing method of packaging body] The following describes a manufacturing method for the package 100. The package 100 is manufactured in the following procedure.

[0054] (a) A first protective plate 31 having a size 10 cm or more larger in both length and width than the size of the light controlling sheet 11 to be packed is placed on a workbench. Then, a first protective sheet 21 having the same size as the first protective plate 31 is placed on top of the first protective plate 31. Then, the first protective sheet 21 and the first protective plate 31 are fixed together with adhesive tape 17 at eight or more points.

[0055] (b) The light controlling sheet 11 is placed in the center of the first protective sheet 21 with the side with the product label facing up. Then, the outer periphery 13 of the light controlling sheet 11 and the first protective sheet 21 are all fixed together, including the corners, with the first easily peelable tape 16a.

[0056] (c) Using a squeegee or the like, the adhesive surface of the first easily peelable tape 16a is brought into close contact with the outer periphery 13 so that the adhesive surface of the first easily peelable tape 16a conforms to the end face shape of the outer periphery 13 of the light adjusting sheet 11. Then, the base end 12b and the tip end 12c of the flexible wiring board 12 are fixed with the second easily peelable tape 16b.

[0057] (d) A second protective sheet 22 of the same size as the first protective sheet 21 is placed on top of the light controlling sheet 11. Then, a second protective plate 32 of the same size is placed on top of the second protective sheet 22. Then, the second protective plate 32 and the second protective sheet 22 are fixed together at eight or more points with adhesive tape 17.

[0058] (e) The first protective plate 31 and the second protective plate 32 are fixed at four or more points with adhesive tape 17. Then, a label sticker indicating that it is a packaged product is affixed to the upper surface of the second protective plate 32.

[0059] (f) A stretch film 41 is wrapped around the first protective plate 31, the second protective plate 32, and the multiple sheets sandwiched between the first protective plate 31 and the second protective plate 32, by wrapping it around two or more times in both the vertical and horizontal directions and then fixing it. Then, vinyl tape is applied to the four corners, and the four corners are crimped and fixed. Then, the whole is covered twice with bubble cushioning material. Finally, a label sticker indicating that it is a packaged product is attached to the package 100, and the packaging work for manufacturing the package 100 in this embodiment is completed.

[0060] [Effect] The entire outer peripheral portion 13 of the light controlling sheet 11 is fixed to the first protective sheet 21, so that the position of the sealing portion 11h in the light controlling sheet 11 can be prevented from shifting relative to the first protective sheet 21. The first protective sheet 21 is fixed to the first protective plate 31, so that the position of the first protective sheet 21 can be prevented from shifting relative to the first protective plate 31. The second protective sheet 22 is fixed to the second protective plate 32, so that the position of the second protective sheet 22 can be prevented from shifting relative to the second protective plate 32. The first protective plate 31 is fixed to the second protective plate 32 to form a protective body 51. This makes it possible to prevent the position of the second protective plate 32 from shifting relative to the first protective plate 31. In other words, it is possible to prevent the sealing portion 11h from rubbing against the sealing portion 11h due to the position of the sealing portion 11h in the light controlling sheet 11 being shifted within the protective body 51.

[0061] Pressure is applied to the protective body 51 in the thickness direction of the light-adjusting sheet 11 by the stretch film 41. As a result, the protective plates 31 and 32 constituting the protective body 51 are deformed along the surface shape of the light-adjusting sheet 11 by the pressure. Therefore, inside the protective body 51, it is possible to suppress the position of the sealing portion 11h in the light-adjusting sheet 11 from being shifted due to vibration. At this time, it is possible to suppress rubbing of the sealing portion 11h due to the position of the light-adjusting sheet 11 being shifted due to deformation and breakage of the protective sheets 21 and 22 due to the force applied to the light-adjusting sheet 11, peeling of the easily peelable tapes 16a and 16b from the first protective sheet 21, etc.

[0062] In particular, when the packages 101 are stacked vertically during transportation, a large force that tries to shift the light-adjusting sheet 11 in the planar direction is generated due to vibration in the planar direction of the light-adjusting sheet 11, which is the direction of gravity. "Stacked vertically" refers to a state in which the packages 101 are transported with the surface of the light-adjusting sheet 11 positioned vertically. By applying pressure in the thickness direction of the light-adjusting sheet 11, it is possible to prevent the position of the light-adjusting sheet 11 from shifting in the direction of gravity relative to the protective plates 31 and 32. In other words, regardless of the loading direction during transportation, it is possible to prevent the sealing portion 11h from rubbing due to the position of the light-adjusting sheet 11 being shifted.

[0063] According to the first embodiment, the following effects can be obtained. (1-1) By protecting both sides of the light-controlling sheet 11 from rubbing caused by vibration during transportation, scratches and damage to the light-controlling sheet 11 can be suppressed, and performance degradation of the sealing portion 11h due to peeling of the sealing portion 11h from the light-controlling sheet 11 can be suppressed.

[0064] (1-2) The adhesive strength of the first easily peelable tape 16a is increased by the large contact area between the first easily peelable tape 16a and the outer periphery 13. This makes it possible to prevent the position of the sealing portion 11h of the light controlling sheet 11 from shifting relative to the first protective sheet 21.

[0065] (1-3) The first easily peelable tape 16a fixes the base end 12b of the extending portion 12a to the first protective sheet 21, and the second easily peelable tape 16b fixes the tip end 12c of the extending portion 12a to the first protective sheet 21. The base end 12b of one of the pair of flexible wiring boards 12 is electrically connected to the first transparent electrode layer 11c. This makes it difficult for the position of the flexible wiring board 12 to shift in the planar direction relative to the first transparent electrode film 11a and the first protective sheet 21. This makes it possible to suppress the application of force to the joint portion between the first transparent electrode film 11a and the flexible wiring board 12.

[0066] (1-4) The first easily peelable tape 16a fixes the base end 12b of the extending portion 12a to the first protective sheet 21, and the second easily peelable tape 16b fixes the tip end 12c of the extending portion 12a to the first protective sheet 21. The other of the pair of flexible wiring boards 12 has its base end 12b electrically connected to the second transparent electrode layer 11f. This makes it difficult for the position of the flexible wiring board 12 to shift relative to the second transparent electrode film 11d and the first protective sheet 21. This makes it possible to suppress the application of force to the joint portion between the second transparent electrode film 11d and the flexible wiring board 12.

[0067] (1-5) The first protective plate 31 and the first protective sheet 21 are fixed at multiple locations by adhesive tape 17, and the second protective plate 32 and the second protective sheet 22 are fixed at multiple locations by adhesive tape 17. This makes it difficult for the position of the first protective sheet 21 to shift in the planar direction relative to the first protective plate 31, and makes it difficult for the position of the second protective sheet 22 to shift in the planar direction relative to the second protective plate 32. This makes it possible to prevent the position of the light controlling sheet 11 together with the first protective sheet 21 and the position of the light controlling sheet 11 together with the second protective sheet 22 from being lowered due to vibrations caused when the light controlling sheet 11 is transported with its surface oriented in the vertical direction.

[0068] (1-6) The package 100 is wrapped with the stretch film 41 so as to press the second protective plate 32 against the first protective plate 31. This allows pressure to be applied by the stretch film 41 from a direction perpendicular to the surface of the light-adjusting sheet 11 sandwiched between the first protective plate 31 and the second protective plate 32. This makes it possible to suppress movement of the light-adjusting sheet 11 in the surface direction due to vibration during transportation and the light-adjusting sheet 11's own weight.

[0069] Second embodiment The configuration of a light controlling sheet package 101, which is a form in which a plurality of light controlling sheets 11 are transported or stored, will be described. Below, the configuration of the package 101 that differs from the package 100 will be mainly described, and descriptions that overlap with the package 100 will be omitted.

[0070] [Package composition] 7, a first protective plate 31, a second protective plate 32, and a plurality of sheets sandwiched between the first protective plate 31 and the second protective plate 32 constitute one protective body 51. The plurality of sheets are a first protective sheet 21, a light control sheet 11, and a second protective sheet 22.

[0071] The package 101 includes a plurality of stacked protective bodies 51, and among the mutually adjacent protective bodies 51, the first protective plate 31 in one protective body 51 is the second protective plate 32 in the other protective body 51. In other words, the package 101 includes the first protective plate 31, the second protective plate 32, and a plurality of third protective plates 33. In the protective body 51 including 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 including the third protective plate 33 as the lower protective plate, the third protective plate 33 is the first protective plate 31.

[0072] 6, in the package 101, a plurality of stacked protective bodies 51 are wrapped with a stretch film 41 so as to press the second protective plate 32 against the first protective plate 31. The stacked protective bodies 51 are fixed by wrapping the stretch film 41, for example, two or more times in each of the vertical and horizontal directions.

[0073] It is preferable that 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 wrapped around them. By deforming the first protective plate 31, the second protective plate 32, and the third protective plate 33 in the thickness direction, the surface shapes of the first protective plate 31, the second protective plate 32, and the third protective plate 33 follow the surface shape of the light controlling sheet 11. It is possible to suppress deformation of the sandwiched light controlling sheet 11 in the thickness direction, and to suppress the position of the light controlling sheet 11 from moving in the surface direction relative to the first protective plate 31, the second protective plate 32, and the third protective plate 33.

[0074] The third protective plate 33, which is more numerous than the protective plates 31 and 32 in the packaging body 101, is thinner than the protective plates 31 and 32, thereby making it possible to reduce the overall thickness of the packaging body 101. This allows more protective bodies 51 to be packed while keeping the thickness of the packaging body 101 thin.

[0075] [Manufacturing method of packaging body] Next, a method for manufacturing the package 101 will be described. The package 101 is manufactured in the following procedure.

[0076] (a) A first protective plate 31 having a size 10 cm or more larger in both length and width than the size of the light controlling sheet 11 to be packed is placed on a workbench. Then, a first protective sheet 21 having the same size as the first protective plate 31 is placed on top of the first protective plate 31. Then, the first protective sheet 21 and the first protective plate 31 are fixed together with adhesive tape 17 at eight or more points.

[0077] (b) With the side with the product label affixed facing up, the light controlling sheet 11 is placed in the center of the first protective sheet 21. Then, the outer periphery 13 of the light controlling sheet 11 and the first protective sheet 21, including the corners, are all fixed together by the first easily peelable tape 16a.

[0078] (c) Using a squeegee or the like, the adhesive surface of the first easily peelable tape 16a is brought into close contact with the outer periphery 13 so that the adhesive surface of the first easily peelable tape 16a conforms to the end face shape of the outer periphery 13 of the light adjusting sheet 11. Then, the base end 12b and the tip end 12c of the flexible wiring board 12 are fixed with the second easily peelable tape 16b.

[0079] (d) A second protective sheet 22 of the same size as the first protective sheet 21 is placed on top of the light adjusting sheet 11. Then, a third protective plate 33 of the same size is placed on the second protective sheet 22. Then, the third protective plate 33 and the second protective sheet 22 are fixed together with adhesive tape 17 at eight or more points.

[0080] (e) First protective sheet 21 having the same size as third protective plate 33 is placed on third protective plate 33. Then, first protective sheet 21 and third protective plate 33 are fixed together with adhesive tape 17 at eight or more points.

[0081] (f) With the side with the product label affixed facing up, the light controlling sheet 11 is placed in the center of the first protective sheet 21. Then, the outer periphery 13 of the light controlling sheet 11 and the first protective sheet 21, including the corners, are all fixed together with the first easily peelable tape 16a.

[0082] (g) Using a squeegee or the like, the adhesive surface of the first easily peelable tape 16a is brought into close contact with the outer periphery 13 so that the adhesive surface of the first easily peelable tape 16a conforms to the end face shape of the outer periphery 13 of the light adjusting sheet 11. Then, the base end 12b and the tip end 12c of the flexible wiring board 12 are fixed with the second easily peelable tape 16b.

[0083] (h) The steps (d) to (g) are repeated until all the light-adjusting sheets 11 to be packed are stacked. If the thickness of the package 101 increases, the shape of the package 101 after the stretch film 41 is wound around it becomes unstable. Therefore, it is preferable that the number of light-adjusting sheets 11 packed in one package 101 be 10 or less.

[0084] (i) When all the light controlling sheets 11 to be packed are stacked, a second protective sheet 22 of the same size as the first protective sheet 21 is placed on top of the light controlling sheet 11. Then, a second protective plate 32 of the same size is placed on the second protective sheet 22. Then, the second protective plate 32 and the second protective sheet 22 are fixed together with adhesive tape 17 at eight or more points.

[0085] (j) The first protective plate 31 and the second protective plate 32 are fixed at four or more points with adhesive tape 17. Then, a label sticker indicating that it is a packaged product is affixed to the upper surface of the second protective plate 32.

[0086] (k) The stretch film 41 is wrapped around the first protective plate 31, the second protective plate 32, and the multiple sheets sandwiched between the first protective plate 31 and the second protective plate 32, by wrapping it around two or more times in both the vertical and horizontal directions and then fixing it. Then, vinyl tape is attached to the four corners and pressed to fix them. Then, the whole is covered twice with bubble cushioning material. Finally, a label sticker indicating that it is a packaged product is attached to the package 101, and the packaging work for manufacturing the package 101 in this embodiment is completed.

[0087] [Effect] Next, the operation of this embodiment will be described. By fixing the entire outer periphery 13 of the multiple light controlling sheets 11 to the first protective sheet 21, it is possible to prevent the position of the sealing portion 11h of each light controlling sheet 11 from shifting relative to the first protective sheet 21. By fixing the first protective sheet 21 to the first protective plate 31, it is possible to prevent the position of the first protective sheet 21 from shifting relative to the first protective plate 31. By fixing the first protective plate 31 to each of the separate second protective plates 32, multiple protective bodies 51 are formed. Thereby, it is possible to prevent the position of the second protective plate 32 from shifting relative to the first protective plate 31 within the multiple protective bodies 51.

[0088] Pressure is applied to the multiple protective bodies 51 in the thickness direction of the light-adjusting sheet 11 by the stretch film 41. The first protective plate 31, the second protective plate 32, and the third protective plate 33 constituting the multiple protective bodies 51 are deformed by the pressure to conform to the surface shape of the light-adjusting sheet 11. For this reason, inside each protective body 51, it is possible to suppress the position of the sealing portion 11h in the light-adjusting sheet 11 from shifting due to vibration.

[0089] In particular, when the packages 101 are stacked vertically during transportation, a large force that tries to shift the light-adjusting sheet 11 in the planar direction, which is the direction of gravity, is generated due to vibration in the planar direction of the light-adjusting sheet 11. "Stacked vertically" refers to a state in which the packages 101 are transported with the surface of the light-adjusting sheet 11 positioned vertically. By applying pressure in the thickness direction of each light-adjusting sheet 11, it is possible to prevent the position of each light-adjusting sheet 11 from shifting in the direction of gravity relative to the protective plates 31 and 32. In other words, regardless of the loading direction during transportation, it is possible to prevent the sealing portion 11h from rubbing due to the position of the light-adjusting sheet 11 being shifted.

[0090] Moreover, by pressing the vinyl tape at the four corners, the corners of the first protective plate 31, the second protective plate 32, and the multiple third protective plates 33 are collectively fixed. Therefore, it is possible to suppress the positional relationship of the light controlling sheet 11 in the mutually adjacent protective bodies 51 from shifting in the surface direction of the light controlling sheet 11, thereby preventing the sealing portions 11h from rubbing against each other.

[0091] According to the second embodiment, the following effects can be obtained. (2-1) By protecting both sides of each light-controlling sheet 11 from rubbing caused by vibration during transportation, scratches and damage to the light-controlling sheet 11 can be suppressed, and performance degradation of the sealing portion 11h due to peeling of the sealing portion 11h from the light-controlling sheet 11 can be suppressed.

[0092] (2-2) The first protective plate 31, the second protective plate 32, and the multiple sheets sandwiched between the first protective plate 31 and the second protective plate 32 constitute one protective body 51. The package 101 includes multiple protective bodies 51 stacked on top of each other, and the first protective plate 31 in one protective body 51 is the second protective plate 32 in the other protective body 51 among the mutually adjacent protective bodies 51. In the mutually adjacent protective bodies 51, the first protective plate 31 in one protective body 51 also serves as the second protective plate 32 in the other protective body 51, so that multiple protective bodies 51 are stacked with a small number of protective plates 31, 32. For this reason, multiple light control sheets 11 can be packaged as one package 101 with a small number of protective plates 31, 32.

[0093] (2-3) The third protective plate 33 is thinner than the protective plates 31 and 32. The third protective plate 33, which is used in greater numbers in one packaging body 101, is thinner than the protective plates 31 and 32, so that the thickness of the entire packaging body 101 is thinner. For this reason, more protective bodies 51 can be packed in one packaging body 101 while keeping the thickness of the entire packaging body 101 thin. That is, more light controlling sheets 11 can be packed in one packaging body 101 while keeping the thickness of the entire packaging body 101 thin.

[0094] Third embodiment A description will be given of the configuration of a light controlling sheet package 102, which is the form in which the light controlling sheet 11 is transported or stored. Below, configurations of the package 102 that are different from the packages 100 and 101 will be mainly described, and descriptions that overlap with the packages 100 and 101 will be omitted.

[0095] 8, a first protective plate 31, a second protective plate 32, and a plurality of sheets sandwiched between the first protective plate 31 and the second protective plate 32 constitute a set of protective bodies 52. The plurality of sheets are a first protective sheet 21, a light controlling sheet 11, and a second protective sheet 22. The set of protective bodies 52 includes two light controlling sheets 11. Each light controlling sheet 11 is sandwiched between the first protective sheet 21 and the second protective sheet 22.

[0096] In addition, one light controlling sheet 11 and another light controlling sheet 11 may be stacked via only one first protective sheet 21, or may be stacked via only one second protective sheet 22. One light controlling sheet 11 and another light controlling sheet 11 may be stacked via two protective sheets 21, 22.

[0097] The number of light controlling sheets 11 provided in one set of protective bodies 52 may be one, or three or more. A plurality of locations of first protective sheet 21 may be releasably fixed to first protective plate 31 by adhesive tape 17, or adhesive tape 17 may be omitted and first protective plate 31 may not be fixed. A plurality of locations of second protective plate 32 may be releasably fixed to second protective sheet 22 by adhesive tape 17, or adhesive tape 17 may be omitted and second protective plate 32 may not be fixed to first protective plate 31.

[0098] The sealing portion 11h of the light controlling sheet 11 may be fixed to the first protective sheet 21 by the first easily peelable tape 16a, or the first easily peelable tape 16a may be omitted and the sealing portion 11h does not have to be fixed to the first protective sheet 21. The extending portion 12a of the flexible wiring board 12 may be fixed to the first protective sheet 21 by the second easily peelable tape 16b, or the second easily peelable tape 16b may be omitted and the sealing portion 11h does not have to be fixed to the first protective sheet 21.

[0099] As shown in Fig. 9, the protective body 52 is wrapped with a stretch film so as to press the second protective plate 32 against the first protective plate 31. The package 102 of the light controlling sheet 11 includes a plurality of cushioning members 61. The protective body 52 having a rectangular plate shape has four corners 55. The protective body 52 includes one cushioning member 61 at each corner. The corners 55 of the protective body 52 are the parts of the end face of the protective body 52 that are most likely to deform due to stress. The cushioning members 61 reduce the transmission of stress applied from the outside to the protective body 52 to the corners 55 of the protective body 52.

[0100] The cushioning member 61 has a rectangular parallelepiped shape. The cushioning member 61 has a slit 62 in the middle in the thickness direction of the protector 52, into which the corner 55 of the protector 52 is inserted. The slit 62 is partitioned into the cushioning member 61 as a flat plate-like space that follows the shape of the corner 55 of the protector 52. The constituent material of the cushioning member 61 may be a cardboard plate or a foamed resin.

[0101] As shown in FIG. 10, a package 102 of the light-adjusting sheet 11 includes a plurality of sets of protective bodies 52, a cushioning material 61, and a package box 71. In the package 102, the plurality of sets of protective bodies 52 and cushioning material 61 are housed in one package box 71. The material of the package box 71 is preferably light, strong, durable, and inexpensive. The material of the package box 71 may be a corrugated board. The material of the package box 71 may be a single-layered corrugated board, or a corrugated board having a two-layer structure such as BI-WALL (registered trademark). When improved mechanical strength is required for the package box 71, the thickness of the corrugated board having a two-layer structure is preferably 10 mm or more.

[0102] The packing box 71 may be an A-type cardboard box having a flap as an upper wall, or a B-type cardboard box having a body and a lid. The multiple sets of protective bodies 52 are stacked inside the packing box 71 so that the cushioning members 61 provided on the respective sets of protective bodies 52 are in contact with each other in the vertical direction.

[0103] 11, in one set of protective bodies 52, the total thickness of the light-adjusting sheet 11, the first protective sheet 21, and the second protective sheet 22 in the thickness direction DT of the light-adjusting sheet 11 is a sheet thickness T2. The thicknesses of the first protective plate 31 and the second protective plate 32 in the thickness direction DT of the light-adjusting sheet 11 are each a plate thickness T3.

[0104] The interval between the slits 62 in the thickness direction DT of the light controlling sheet 11 is a slit height T62. The slit height T62 may be equal to, smaller than, or larger than the sum of the sheet thickness T2 and the two plate thicknesses T3 in one set of protectors 52. When the slit height T62 is smaller than the sum of the sheet thickness T2 and the two plate thicknesses T3, misalignment of the corners of the protectors 52 with respect to the slits 62 is suppressed.

[0105] The increase in size of the light-adjusting sheet 11 promotes the increase in size of the protective body 52 itself. The larger the size of the light-adjusting sheet 11, the easier it is for the protective body 52 itself to bend under its own weight. When the protective body 52 that bends under its own weight comes into contact with a structure such as another protective body 52 or the bottom surface of the packaging box 71, stress and impact are easily transmitted to the light-adjusting sheet 11 through the contact. The thickness T61 of the buffer member 61 in the thickness direction DT of the light-adjusting sheet 11 may be a size that separates the protective body 52 from the bottom surface of the packaging box 71 even when the protective body 52 itself bends under its own weight. Furthermore, the thickness T61 of the buffer member 61 in the thickness direction DT of the light-adjusting sheet 11 determines the interval G5 between the mutually adjacent protective bodies 52. The thickness T61 of the buffer member 61 may be a size that does not allow the protective body 52 to come into contact with other structures even when the protective body 52 itself bends under its own weight. When it is required that the protector 52 be prevented from contacting other structures, the thickness T61 of the buffer member 61 is preferably 30 mm or more, and more preferably 40 mm or more.

[0106] The length L2 of the slit 62 in the surface direction DL of the light controlling sheet 11 is the length of the protective body 52 supported by the buffer member 61. The greater the length L2 of the slit 62, the greater the length of the protective body 52 supported by the buffer member 61, thereby suppressing displacement of the protective body 52 relative to the buffer member 61, i.e., bending of the protective body 52 due to its own weight. When it is required to suppress bending of the protective body 52, the length L2 of the slit 62 is preferably 1 / 20 or more of the length of the protective body 52 in the surface direction DL of the light controlling sheet 11, and more preferably 1 / 10 or more.

[0107] [Example] A specific example of the package 102 in the third embodiment will be described below. First, plastic cardboard was used for the first protective plate 31 and the second protective plate 32 of the embodiment. A laminate of a foamed polyethylene sheet (Minafoam (registered trademark): manufactured by Sakai Chemical Industry Co., Ltd.) and multiple sheets of interleaf paper was used for the first protective sheet 21 and the second protective sheet 22 of the embodiment. Next, one light control sheet 11 was sandwiched between the foamed polyethylene sheet and the multiple sheets of interleaf paper, and the multiple foamed polyethylene sheets, the multiple sheets of interleaf paper, and the two light control sheets 11 were sandwiched between the first protective plate 31 and the second protective plate 32. In this way, a protective body 52 of the embodiment having a rectangular plate shape was obtained.

[0108] Next, the cushioning member 61 was formed using a 10 mm thick cardboard sheet as the constituent material of the cushioning member 61. Then, the cushioning member 61 was attached to each of the four corners 55 of the protective body 52 of the example, and five protective bodies 52 were stacked in one packaging box 71 to obtain the packaged body 102 of the example. That is, the packaged body 102 of the example was obtained by storing ten light controlling sheets 11 in one packaging box 71. Also, the packaged body 102 of the example, in which the cushioning member 61 was omitted, was obtained as the packaged body 102 of the reference example.

[0109] The dimensions of the packaging box 71, protective plates 31, 32, protective sheets 21, 22, and cushioning member 61 for storing ten light adjusting sheets 11 are shown below. The dimensions of the packaging box 71 and the dimensions of the cushioning member 61 are shown as length x width x height, where the length is the length in the surface direction DL, the width is the length in the other surface direction DL, and the height is the length in the thickness direction DT. The dimensions of the protective plates 31, 32, and protective sheets 21, 22 are shown as length x width, where the length is the length in the surface direction DL and the width is the length in the other surface direction DL. - Packing box 71 dimensions: 1085mm x 810mm x 230mm Dimensions of protective plates 31 and 32: 1045mm x 770mm Thickness T3 of protective plates 31 and 32: 4mm Dimensions of protective sheets 21 and 22: 1055mm x 780mm Thickness of protective sheets 21 and 22: 3.5 mm Dimensions of cushioning material 61: 110mm x 110mm x 42mm Thickness of cushioning material 61: T61: 42mm Length of slit 62 L2: 90mm Slit height T62: 22mm

[0110] The respective quantities of the protective plates 31, 32, the foamed polyethylene sheets, the interleaf papers, and the cushioning members 61 used to accommodate the ten light controlling sheets 11 are shown below. Quantity of protective plates 31 and 32: 10 pieces Quantity of foamed polyethylene sheets: 10 sheets -Number of sheets: 45 Quantity of cushioning material 61: 20 pieces

[0111] FIG. 12 shows the evaluation results of the vibration test using the packaging body 102 of the embodiment and the reference example, and the vibration test when two to five packaging bodies 102 are stacked. The vibration test was performed by applying vibration in the vertical direction and the horizontal direction using a method conforming to JIS Z0200:2020 (8.4 vibration test level 2). Then, based on the exterior packaging of the packaging body 102 before the vibration test and the position of the protective body 52 in the packaging box 71, it was determined whether or not the exterior packaging of the packaging body 102 after the vibration test was displaced, and whether or not the protective body 52 was displaced. In addition, based on the appearance of the light-controlling sheet 11 before the vibration test, it was determined whether or not the appearance of the light-controlling sheet 11 was scratched. In addition, it was visually determined whether or not dust was generated inside the packaging box 71 after the vibration test compared to the inside of the packaging box 71 before the vibration test.

[0112] In FIG. 12, a mark "○" is attached to the level where no misalignment is found in any of the packaging boxes 71, and a mark "△" is attached to the level where misalignment is found in none of the protective bodies 52. A mark "△" is attached to the level where misalignment is found in only some of the packaging boxes 71, and a mark "X" is attached to the level where misalignment is found in all of the packaging boxes 71. A mark "○" is attached to the level where no scratches are found in any of the light-adjusting sheets 11, a mark "△" is attached to the level where scratches are found in less than half of the light-adjusting sheets 11, and a mark "X" is attached to the level where scratches are found in more than half of the light-adjusting sheets 11. A mark "○" is attached to the level where no dust generation is found visually in any of the packaging boxes 71, and a mark "△" is attached to the level where dust generation is found visually in some of the packaging boxes 71.

[0113] 12, it was confirmed that the exterior packaging of the reference example not provided with the cushioning member 61 did not cause any misalignment in the package 102 when the number of light-control sheets 11 was in the entire range from 10 to 50 sheets, i.e., when the load was in the entire range from 4 kg to 20 kg. It was also confirmed that the exterior packaging of the example did not cause any misalignment in the package 102 when the number of light-control sheets 11 was in the entire range from 10 to 50 sheets.

[0114] 12, it was found that the position of the protective body 52 in the reference example had a large deviation as the number of light adjusting sheets 11 increased from 10 to 50. In contrast, it was found that the position of the protective body 52 in the example did not show any deviation over the entire range of the number of light adjusting sheets 11 from 10 to 50.

[0115] 12, it was confirmed that the light controlling sheet 11 of the reference example was more susceptible to scratches as the number of light controlling sheets 11 increased from 10 to 50. In contrast, it was confirmed that the light controlling sheet 11 of the example was not scratched over the entire range of the number of light controlling sheets 11 from 10 to 50.

[0116] 12, it was confirmed that the light controlling sheet 11 of the reference example was more susceptible to scratches as the number of light controlling sheets 11 increased from 10 to 50. In contrast, it was confirmed that the light controlling sheet 11 of the example was not scratched over the entire range of the number of light controlling sheets 11 from 10 to 50.

[0117] 12, it was confirmed that the package 102 of the reference example was more likely to generate dust as the number of light adjusting sheets 11 increased from 10 to 50. In contrast, it was confirmed that the package 102 of the example did not generate dust over the entire range of the number of light adjusting sheets 11 from 10 to 50.

[0118] According to the third embodiment, the following effects can be obtained. (3-1) Since the cushioning material 61 is disposed on the edge of the protective body 52 so as to separate the corner portion 55 of the protective body 52 from the inner surface 71W of the packaging box 71 in the plane direction DL of the light controlling sheet 11, the stress and impact transmitted from the packaging box 71 to the protective body 52 are softened for the protective body 52. ​​As a result, the protection performance of the quality of the light controlling sheet 11 in the packaging body 102 is improved.

[0119] (3-2) Since the buffer member 61 has the slits 62 into which the corners 55 of the protector 52 are inserted, the corners 55 of the protector 52 are accommodated in the slits 62 of the buffer member 61 and are covered by the buffer member 61. This improves the effectiveness of protection for the corners 55 of the protector 52, and therefore the effectiveness of protection for the corners of the light controlling sheet 11.

[0120] (3-3) When the slit height T62 is thicker than the thickness of the protector 52, the position of the corners of the protector 52 is less likely to shift relative to the cushioning member 61. This prevents the light controlling sheet 11 from being rubbed or deformed due to the position of the corners 55 of the protector 52 being shifted relative to the cushioning member 61.

[0121] (3-4) Increasing the size of the light-adjusting sheet 11 promotes the increase in size of the protective body 52 itself. The larger the size of the light-adjusting sheet 11, the easier it is for the protective body 52 itself 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 light-adjusting sheet 11 through the contact. In this regard, the buffer member 61 is disposed on the edge of the protective body 52 so that the protective body 52 is separated from the inner surface 71W of the packaging box 71 in the thickness direction DT of the light-adjusting sheet 11. For this reason, the stress and impact transmitted from the packaging box 71 to the protective body 52 are softened with respect to the protective body 52. ​​In other words, the stress and impact transmitted from the packaging box 71 to the light-adjusting sheet 11 are softened with respect to the light-adjusting sheet 11. As a result, the protection performance of the quality of the light-adjusting sheet 11 in the packaging body 102 is improved.

[0122] (3-5) The cushioning material 61 is disposed on the edge of the protective body 52 so that the protective body 52 is separated from the other protective bodies 52 in the thickness direction DT of the light-adjusting sheet 11. Therefore, the stress and impact transmitted between the protective bodies 52 are alleviated between the protective bodies 52. That is, the stress and impact transmitted from the other protective bodies 52 to the light-adjusting sheet 11 are alleviated. As a result, the protection performance of the quality of the light-adjusting sheet 11 in the package 102 is further improved.

[0123] [Example of change] The above embodiment can be modified as follows: The above embodiment and modifications can be combined with each other as long as they are not technically inconsistent.

[0124] The first protective plate 31, the second protective plate 32, and the third protective plate 33 may have one or more holes in the center. Even if there are one or more holes in the center, the light controlling sheet 11 can be prevented from moving in the planar direction when pressure is applied by the stretch film 41.

[0125] The protective sheets 21, 22 may be larger than the first protective plate 31, the second protective plate 32, and the third protective plate 33. For example, the protective plates 31, 32, 33 and the protective sheets 21, 22 are fixed to each other with an adhesive tape 17 having an adhesive layer on both sides, so that the protective sheets 21, 22, which are larger than the protective plates 31, 32, 33, can be fixed to the protective plates 31, 32, 33.

[0126] In FIG. 5, the light-adjusting sheet 11 may be arranged upside down on the first protective sheet 21. That is, the light-adjusting sheet 11 may be arranged in a state where the surface of the light-adjusting sheet 11 on the sealing portion 11h side is in contact with the surface of the first protective sheet 21. In this state, a part of the sealing portion 11h is covered by the first protective sheet 21, but the remaining part is covered by the first easy peeling tape 16a so that there is no exposed part. Therefore, this state is included in the state where "the first easy peeling tape 16a covers the entire sealing portion 11h". That is, the first easy peeling tape 16a covers the entire sealing portion 11h and fixes the light-adjusting sheet 11 to the first protective sheet 21. Furthermore, even in this state, it is preferable that the first easy peeling tape 16a covers the entire outer periphery 13 of the light-adjusting sheet 11 so as to follow the end face shape at the outer periphery 13 of the light-adjusting sheet 11.

[0127] A squeegee may also be used for the second easily peelable tape 16b that fixes the tip portion 12c of the extension portion 12a of the flexible wiring board 12 to the first protective sheet 21. That is, the flexible wiring board 12 may be fixed to the first protective sheet 21 by the second easily peelable tape 16b so as to conform to the outer shape of the flexible wiring board 12. Since the adhesive strength of the second easily peelable tape 16b is increased, it is possible to further prevent the flexible wiring board 12 from shifting in position with respect to the first protective sheet 21.

[0128] In the second embodiment, the protective bodies 51 in the first embodiment may be stacked to form the package 101. Since the protective bodies 51 constituting the package 101 all have the same configuration, the package 101 can be manufactured in a simple procedure by manufacturing a plurality of protective bodies 51 having the same configuration and then stacking the plurality of protective bodies 51.

[0129] In the second embodiment, the sizes of the multiple light adjusting sheets 11 to be packed may be different. Among the multiple light adjusting sheets 11, only one light adjusting sheet 11 may be different in size, or all the light adjusting sheets 11 may be different in size.

[0130] In the third embodiment, the first protective plate 31 may have a cushioning function to protect the light controlling sheet 11 on the surface facing the light controlling sheet 11. In this case, the packaging body 102 for the light controlling sheet 11 may omit the first protective sheet 21. The second protective plate 32 may have a cushioning function to protect the light controlling sheet 11 on the surface facing the light controlling sheet 11. In this case, the packaging body 102 for the light controlling sheet 11 may omit the second protective sheet 22.

[0131] In the third embodiment, the protective body 52 does not have to be wrapped with the stretch film 41 . The cushioning member 61 may be disposed at an edge of the protector 52 other than at a corner. For example, the slit 62 of the cushioning member 61 may be linear along the long side of the protector 52, and the cushioning member 61 may be disposed at the long side of the protector 52 so that the slit 62 sandwiches a part of the long side of the protector 52. The slit 62 of the cushioning member 61 may be linear along the short side of the protector 52, and the cushioning member 61 may be disposed at the short side of the protector 52 so that the slit 62 sandwiches a part of the short side of the protector 52.

[0132] As a result, the buffer members 61 are disposed on each side of the protector 52 so as to separate the corners 55 of the protector 52 from the inner surface 71W of the packaging box 71 in the plane direction DL of the light controlling sheet 11. Even with this configuration, it is possible to obtain effects similar to those of (3-1) to (3-3) above. Alternatively, the buffer members 61 are disposed on each side of the protector 52 so as to separate the protector 52 from the inner surface 71W of the packaging box 71 in the thickness direction DT of the light controlling sheet 11. Even with this configuration, it is possible to obtain effects similar to those of (3-4) and (3-5) above.

[0133] According to the above embodiment and modified examples, the following technical ideas can be derived. [Appendix 1] A light control sheet package, The light-adjusting sheet includes a first transparent electrode film, a second transparent electrode film, a sealing portion that seals a gap between the first transparent electrode film and the second transparent electrode film at an outer periphery of the light-adjusting sheet, and a liquid crystal composition that is sealed in the gap surrounded by the sealing portion, The packaging body is A protective body and a packaging box for accommodating the protective body. The protector is The light adjusting sheet is provided with a first protective plate and a second protective plate that sandwich the entire light adjusting sheet, The packaging body includes a cushioning member disposed on an edge of the protective body so as to separate a corner of the protective body from an inner surface of the packaging box in a surface direction of the light adjusting sheet. Light-adjusting sheet packaging.

[0134] The corners of the protective body in which the light-adjusting sheet is sandwiched are the parts of the end surface of the protective body that are most likely to deform due to stress. In this regard, according to the configuration of Supplementary Note 1, the cushioning material is disposed on the edge of the protective body so that the corners of the protective body are spaced apart from the inner surface of the packaging box. Therefore, the stress and impact transmitted from the packaging box to the protective body are softened to the protective body. That is, the stress and impact transmitted from the packaging box to the light-adjusting sheet are softened to the light-adjusting sheet. As a result, whether the sealing portion is fixed to the protective sheet by the easy-peel tape or not, the deterioration of the quality of the light-adjusting sheet caused by the stress and impact acting on the protective body from the packaging box is suppressed. And the protection performance of the quality of the light-adjusting sheet in the package is improved.

[0135] [Appendix 2] A light control sheet package, The light-adjusting sheet includes a first transparent electrode film, a second transparent electrode film, a sealing portion that seals a gap between the first transparent electrode film and the second transparent electrode film at an outer periphery of the light-adjusting sheet, and a liquid crystal composition that is sealed in the gap surrounded by the sealing portion, The packaging body is A protective body and a packaging box for accommodating the protective body. The protector is The light adjusting sheet is provided with a first protective plate and a second protective plate that sandwich the entire light adjusting sheet, The packaging body includes a cushioning member disposed on an edge of the protective body so as to separate the protective body from the inner surface of the packaging box in the thickness direction of the light controlling sheet. Light-adjusting sheet packaging.

[0136] Increasing the size of the light-adjusting sheet leads to an increase in the size of the protective body itself. The larger the size of the light-adjusting sheet, the more likely the protective body itself is to bend under its own weight. When a protective body that bends under its own weight comes into contact with a structure other than the protective body, stress and impact are likely to be transmitted to the light-adjusting sheet through the contact.

[0137] In this regard, according to the configuration of Supplementary Note 2, the cushioning member is disposed on the edge of the protective body so that the protective body is separated from the inner surface of the packaging box in the thickness direction of the light-adjusting sheet. Therefore, the stress and impact transmitted from the packaging box to the protective body are mitigated to the protective body. In other words, the stress and impact transmitted from the packaging box to the light-adjusting sheet are mitigated to the light-adjusting sheet. As a result, whether the sealing portion is fixed to the protective sheet by an easily peelable tape or not, deterioration in the quality of the light-adjusting sheet caused by the stress and impact acting on the protective body from the packaging box is suppressed. And the protection performance of the quality of the light-adjusting sheet in the package is improved.

[0138] [Appendix 3] A package for a light-adjusting sheet, the light-adjusting sheet comprising 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 light-adjusting sheet, and a liquid crystal composition sealed in the gap surrounded by the sealing portion, the package comprising the light-adjusting sheet, a first protective plate that sandwiches the entire light-adjusting sheet, and a second protective plate, a first protective sheet that is sandwiched between the light-adjusting sheet and the first protective plate and in contact with one entire surface of the light-adjusting sheet, a second protective sheet that is sandwiched between the light-adjusting sheet and the second protective plate and in contact with the other entire surface of the light-adjusting sheet, and an easily-peelable tape that covers the entire sealing portion and fixes the light-adjusting sheet to the first protective sheet.

[0139] In the package, the protective film has an adhesive layer facing the light-adjusting sheet. The protective film is attached to the light-adjusting sheet via the adhesive layer. The adhesive layer is required to have an adhesive strength that is easy to peel off so that the light-adjusting sheet does not peel off within the sheet when the protective film is peeled off from the light-adjusting sheet.

[0140] On the other hand, the outer periphery of the light-adjusting sheet is the end that adheres to the protective film, and therefore the protective film is more easily peeled off than the center of the light-adjusting sheet. Therefore, the protective film is required to be easily peeled off, and the protective film is easily peeled off at the outer periphery of the light-adjusting sheet. When the light-adjusting sheet is vibrated during transportation of the package, the protective film begins to peel off from the outer periphery of the light-adjusting sheet. As a result, the surface of the light-adjusting sheet may rub against other members, or the surface of the sealing part may rub against other members, which may impair the function of the light-adjusting sheet.

[0141] According to the configuration of [Appendix 3] above, the first protective plate reduces the impact applied to the first protective sheet from the outside of the package and the friction with external members. The second protective plate reduces the impact applied to the second protective sheet from the outside of the package and the friction with external members. The first protective sheet and the second protective sheet further protect both sides of the light-controlling sheet from impact and friction. At this time, the easy-peel tape and the first protective sheet cover the entire sealing portion, and the sealing portion is fixed to the first protective sheet by the easy-peel tape, so that friction between the sealing portion and the first protective sheet and friction between the light-controlling sheet and the first protective sheet are suppressed. Therefore, by protecting both sides of the light-controlling sheet from friction caused by vibration during transportation, scratches and damage to the light-controlling sheet can be suppressed, and deterioration of the performance of the sealing portion due to peeling of the sealing portion from the light-controlling sheet can be suppressed.

[0142] [Appendix 4] The easily peelable tape covers the entire outer periphery of the light controlling sheet so as to conform to the edge shape of the outer periphery of the light controlling sheet. According to the configuration of [Appendix 4], since a gap is unlikely to be formed between the easily peelable tape and the end face of the outer periphery of the light controlling sheet, the contact area between the easily peelable tape and the outer periphery is increased, and the adhesive strength of the easily peelable tape is increased. Therefore, it is possible to suppress the position of the sealing part of the light controlling sheet from shifting relative to the first protective sheet.

[0143] [Appendix 5] The easily peelable tape is a first easily peelable tape, the first transparent electrode film includes a first transparent electrode layer, the light control sheet further includes a flexible wiring board connected to the first transparent electrode layer, the flexible wiring board includes an extension portion extending toward the outside of the first transparent electrode film, the first easily peelable tape fixes a base end of the extension portion to the first protective sheet, and the packaging body further includes a second easily peelable tape fixing a tip end of the extension portion to the first protective sheet.

[0144] According to the configuration of [Supplementary Note 5], the flexible wiring board is less likely to shift in position relative to the first transparent electrode film and the first protective sheet, which makes it possible to suppress the application of force to the joint between the first transparent electrode film and the flexible wiring board.

[0145] [Appendix 6] The first protective sheet is fixed at a plurality of locations to the first protective plate by adhesive tape, and the second protective sheet is fixed at a plurality of locations to the second protective plate by adhesive tape.

[0146] According to the configuration of [Appendix 6] above, the position of the first protective sheet is less likely to shift in the planar direction relative to the first protective plate, and the position of the second protective sheet is less likely to shift in the planar direction relative to the second protective plate. This makes it possible to prevent the position of the light controlling sheet together with the first protective sheet and the position of the light controlling sheet together with the second protective sheet from being lowered due to vibrations caused when the light controlling sheet is transported with its surface oriented vertically.

[0147] [Appendix 7] The package is wrapped with a stretch film so as to press the second protective plate against the first protective plate. According to the configuration of [Appendix 7] above, pressure is applied by the stretch film from a direction perpendicular to the surface of the light-adjusting sheet sandwiched between the first and second protective plates. This makes it possible to suppress the light-adjusting sheet from moving in the planar direction due to vibration during transportation and the light-adjusting sheet's own weight.

[0148] [Appendix 8] The first protective plate, the second protective plate, and the multiple sheets sandwiched between the first protective plate and the second protective plate constitute one protective body, and the packaging body includes multiple stacked protective bodies, and among adjacent protective bodies, the first protective plate of one protective body is the second protective plate of the other protective body.

[0149] According to the configuration of [Appendix 8] above, in mutually adjacent protective bodies, the first protective plate of one protective body also serves as the second protective plate of the other protective body, so that multiple protective bodies are stacked with a small number of protective plates. Therefore, multiple light control sheets can be packaged as one package with a small number of protective plates.

[0150] [Appendix 9] One set of protective bodies is composed of the first protective plate, the second protective plate, and a plurality of sheets sandwiched between the first protective plate and the second protective plate, and may include a packaging box for housing the protective bodies, and cushioning members arranged on the edges of the protective body so as to separate the corners of the protective body from the inner surface of the packaging box in the surface direction of the light-adjusting sheet.

[0151] The corners of the protective body are the parts of the end face of the protective body that are most likely to deform due to stress. In this regard, according to the configuration of [Appendix 9] above, the cushioning material is arranged on the edge of the protective body so that the corners of the protective body are separated from the inner surface of the packaging box. This reduces the stress and impact transmitted from the packaging box to the protective body. In other words, the stress and impact transmitted from the packaging box to the light-adjusting sheet is reduced to the light-adjusting sheet. As a result, the protection performance of the quality of the light-adjusting sheet in the packaging body is improved.

[0152] [Appendix 10] The cushioning member may have a shape that conforms to the corner of the protection body and may include a slit into which the corner of the protection body is inserted. According to the configuration of [Appendix 10] above, the corners of the protective body are accommodated in the slits of the buffer member and are covered by the buffer member, which enhances the effectiveness of protection for the corners of the protective body and, in turn, the effectiveness of protection for the corners of the light controlling sheet.

[0153] [Appendix 11] The cushioning member may have a slit into which the corner of the protective body is inserted, and the thickness of the slit in the thickness direction of the light controlling sheet may be thicker than the thickness of the protective body.

[0154] According to the configuration of [Appendix 11] above, the position of the corners of the protective body relative to the cushioning material is less likely to shift, thereby suppressing rubbing or deformation of the light-adjusting sheet caused by the position of the corners of the protective body shifting relative to the cushioning material.

[0155] [Appendix 12] One set of protective bodies is composed of the first protective plate, the second protective plate, and a plurality of sheets sandwiched between the first protective plate and the second protective plate, and may include a packaging box that contains the protective bodies, and a cushioning member that is arranged on the edge of the protective body so as to separate the protective body from the inner surface of the packaging box in the thickness direction of the light-adjusting sheet.

[0156] Increasing the size of the light-adjusting sheet leads to an increase in the size of the protective body itself. The larger the size of the light-adjusting sheet, the more likely the protective body itself is to bend under its own weight. When a protective body that bends under its own weight comes into contact with a structure other than the protective body, stress and impact are likely to be transmitted to the light-adjusting sheet through the contact. In this regard, according to the above-mentioned [Appendix 12] configuration, the buffer member is arranged on the edge of the protective body so that the protective body is separated from the inner surface of the packaging box in the thickness direction of the light-adjusting sheet. Therefore, the stress and impact transmitted from the packaging box to the protective body are softened for the protective body. In other words, the stress and impact transmitted from the packaging box to the light-adjusting sheet are softened for the light-adjusting sheet. As a result, the protection performance of the quality of the light-adjusting sheet in the packaging body is improved.

[0157] [Appendix 13] The present invention may comprise multiple sets of the protective bodies stacked together, and the cushioning member may be arranged on the edges of the protective bodies so as to separate the protective bodies from each other in the thickness direction of the light-adjusting sheet.

[0158] According to the configuration of [Appendix 13] above, the buffer member is arranged on the edge of the protective body so that the protective body is separated from other protective bodies in the thickness direction of the light-adjusting sheet. Therefore, the stress and impact transmitted between the protective bodies are mitigated between the protective bodies. In other words, the stress and impact transmitted from the other protective bodies to the light-adjusting sheet are mitigated. As a result, the protection performance of the quality of the light-adjusting sheet in the package is further improved. [Explanation of symbols]
