Abstract
Description
Technical Field
[0001] The present invention relates to a winding body storage box and a winding body storage device.
Background Art
[0002] Currently, a wound body formed by winding a wrap film, paper, or the like around a core is transported, sold, used, etc. in a state of being stored in a substantially rectangular parallelepiped cosmetic box. Since such a cosmetic box (winding body storage box) is used daily with complicated operations, it is required to have non-slip properties when held by hand. In particular, it is known that a cosmetic box containing a wound body of a polyvinylidene chloride (PVDC) wrap film having a large specific gravity is particularly strongly required to be easy to hold and non-slip.
[0003] Therefore, in recent years, in order to improve the non-slip property when the cosmetic box is held by hand, a technique of providing an uneven structure on the side surface of the cosmetic box (see Patent Document 1) and a technique of applying a non-slip varnish over a wide range on the side surface of the cosmetic box (see Patent Document 2) have been proposed.

Summary of the Invention
Problems to be Solved by the Invention
[0005] However, even if the technique disclosed in Patent Document 1 is adopted, there is a limit to the area and height of the uneven structure that can be imparted to the pressing paper constituting the cosmetic box. Therefore, depending on the way of holding, it may not be possible to touch the unevenness, and the effect of improving the non-slip property may not be obtained. Further, if a non-slip varnish is applied over a wide range as disclosed in Patent Document 2, there is a risk that the productivity may decrease due to poor slipperiness in the assembly process of the cosmetic box.
[0006] This invention has been made in view of these circumstances, and aims to improve the ease of handling of the winding material storage box without reducing productivity. [Means for solving the problem]
[0007] A first aspect of the present invention for achieving the above objective is a winding body storage box configured to house a winding body of film in its internal space, comprising: a storage section having an internal space and an opening formed by a front plate, a bottom plate, a rear plate, and side plates; and a lid attached to the storage section to open and close the opening, having a top plate connected to the upper end of the rear plate and a cover piece connected to the front end of the top plate, wherein a non-slip region having a first dynamic friction coefficient and a slippery region having a second dynamic friction coefficient are formed adjacent to each other in a specific area on at least one surface of the top plate, cover piece, bottom plate, and rear plate, the first dynamic friction coefficient is 0.30 or more and 0.70 or less, the second dynamic friction coefficient is 0.3 or more and 0.7 times the first dynamic friction coefficient, and the area of the non-slip region is 85% or less of the area of the specific region.
[0008] By adopting this configuration, a non-slip area with a relatively high coefficient of dynamic friction and a slippery area with a relatively low coefficient of dynamic friction are formed adjacent to each other in a specific area on at least one surface of the top plate and cover piece of the lid and the bottom plate and rear plate of the storage section. As a result, when a user holds the winding material storage box in their hand, their fingers are naturally guided from the slippery area to the non-slip area, providing a grip that makes it less likely to slip. In this case, the coefficient of dynamic friction of the non-slip area (first coefficient of dynamic friction) is set within a specific range (0.30 or more and 0.70 or less), so that a moderate grip is achieved without compromising the feel of holding it (if the first coefficient of dynamic friction is less than 0.30, the grip is not effective, and if the first coefficient of dynamic friction is greater than 0.70, it is easy to feel sticky and the feel of holding it deteriorates, as well as the slipperiness worsens and productivity decreases, so neither is desirable). Furthermore, since the coefficient of kinetic friction in the sliding area (the second coefficient of kinetic friction) is set within a specific range (0.3 times or more and 0.7 times or less of the first coefficient of kinetic friction), the user's fingers can be appropriately guided into the non-slip area (if the second coefficient of kinetic friction exceeds 0.7 times the first coefficient of kinetic friction, the user's fingers will not be able to slip easily, and if the second coefficient of kinetic friction is less than 0.3 times the first coefficient of kinetic friction, the user's fingers will slip too much and it will be difficult to hold, so neither is desirable).
[0009] In the winding material storage box according to the present invention, a plurality of protrusions can be formed in the non-slip region and the slippery region. In this case, 1 cm in the non-slip region 2 The number of protrusions per unit area and the 1 cm in the smooth region 2 The difference between the number of protrusions per hit and the other can be set to 50 to 600.
[0010] When this configuration is adopted, Spc(1cm) in the non-slip region 2 The difference between the number of bumps on the contact area and the Spc in the smooth area is set within a specific range (50-600), which has the advantage of making the non-slip area easier to recognize and allowing the user to grip unconsciously. If the difference between the two is too small (less than 50), it becomes difficult to recognize the non-slip area, and if the difference is too large (more than 600), the difference in tactile sensation between the smooth and non-slip areas becomes large, making the user more likely to feel uncomfortable, so neither is desirable.
[0011] In the winding material storage box according to the present invention, an anti-slip varnish can be applied to the non-slip region. In this case, the area to which the anti-slip varnish is applied can be set to 10 to 50% of the area of a specific region.
[0012] By adopting this configuration, the application area of the non-slip varnish in the non-slip region is set within a specific range (10-50% of the area of the specific region), making it easier to grip without compromising productivity. If the application area of the non-slip varnish is too small (less than 10% of the area of the specific region), it becomes difficult to grip, and if the application area of the non-slip varnish is too large (more than 50% of the area of the specific region), the slipperiness in the manufacturing process of the storage box deteriorates, reducing productivity, so neither is desirable.
[0013] A second aspect of the present invention is a winding body storage device in which a winding body of film is stored in a winding body storage box according to the first aspect. Here, a polyvinylidene chloride film can be used as the film. [Effects of the Invention]
[0014] According to the present invention, it is possible to improve the ease of handling of the winding material storage box without reducing productivity. [Brief explanation of the drawing]

Mode for Carrying out the Invention
[0016] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the following embodiments are merely preferred application examples, and the scope of application of the present invention is not limited thereto.
[0017] First, the configuration of the winding body storage device 1 according to the present embodiment will be described with reference to FIGS. 1 to 6. In this specification, in the configurations of the winding body storage device 1 and the winding body storage box 10, "upper" and "lower" are based on the posture shown in FIG. 1, that is, the posture when the bottom plate 31 (described later) of the winding body storage box 10 is downward and the lid plate 40 (described later) is upward. Also, the front plate 30 (described later) side of the winding body storage box 10 is "front", and the rear plate 32 (described later) side is "rear". Further, the longitudinal direction (left - right direction) of the winding body storage box 10 is the "X - direction", the front - rear direction orthogonal to the longitudinal direction X of the winding body storage box 10 is the "Y - direction", and the up - down direction of the winding body storage box 10 is the "Z - direction".
[0018] The winding body storage device 1 according to the present embodiment includes, as shown in FIGS. 1 to 3, a winding body storage box 10 and a winding body 11 around which a film F is wound.
[0019] As shown in FIG. 1, the winding body storage box 10 has an overall elongated rectangular parallelepiped shape. The material constituting the winding body storage box 10 is, for example, papers such as cardboard, coated cardboard, corrugated cardboard, etc., but other materials may be appropriately selected and used.
[0020] As shown in Figures 2 and 3, the winding body storage box 10 is configured to house a winding body 11 on which the film F is wound, and includes a storage section 20 having an opening 20a formed at the top and an internal space 20b in which the winding body 11 is housed, and a lid section 21 that opens and closes the opening 20a of the storage section 20.
[0021] As shown in Figures 1 to 4, the storage section 20 includes a front plate 30, a bottom plate 31, a rear plate 32, a side piece 33 on the front plate, a side plate 34, a side piece 35 on the rear plate, a back plate 36, a side piece 37 on the back plate, and so on.
[0022] In the unfolded view of Figure 4, the back plate 36, front plate 30, bottom plate 31, and rear plate 32 each have a rectangular shape that is long in the left-right direction X, and are connected to each other in this order in the front-back direction Y. The side pieces 33 of the front plate have a stepped shape and are connected to both ends of the front plate 30 in the left-right direction X. The side plates 34 have a square shape and are connected to both ends of the bottom plate 31 in the left-right direction X. The side pieces 35 of the rear plate have a roughly square shape and are connected to both ends of the rear plate 32 in the left-right direction X. The side pieces 37 of the back plate are connected to both ends of the back plate 36 in the left-right direction X.
[0023] The front plate 30 has a wavy cutout 30a formed across both ends in the left-right direction X. The surface of the front plate 30 is provided with a temporary fastening member Q for temporarily securing the end of the film F. The back plate 36 has a cutout 36a formed thereon that connects to the connection line (fold line) between the back plate 36 and the front plate 30.
[0024] As shown in Figures 2 and 3, the storage section 20 is formed in the shape of a rectangular parallelepiped with an opening 20a at the top. The front plate 30, bottom plate 31, rear plate 32, and side plates 34 constitute the five wall surfaces of the storage section 20 other than the top surface, and together they form the internal space 20b of the storage section 20. The back plate 36 is folded inward to the front plate 30 and positioned on the back surface of the front plate 30. The part of the front plate 30 above the notch 30a is raised forward, away from the lower part. The part of the back plate 36 above the notch 36a is raised backward, away from the lower part. The rear plate side piece 35 is folded inward to the side plate 34 and covers the inner surface of the side plate 34. The front plate side piece 33 and the back plate side piece 37 are folded inward to the inner surface of the side plate 34 and interposed between the rear plate side piece 35 and the side plate 34.
[0025] As shown in the unfolded view of Figure 4, the lid portion 21 includes a top plate 40, a cover piece 41, a side piece 42 of the top plate, a side piece 43 of the cover piece, an opening piece 44, and so on.
[0026] The top plate 40 and the cover piece 41 have a roughly rectangular shape that is elongated in the left-right direction X, and are connected to each other in the front-back direction Y. The top plate 40 is connected to the upper end of the rear plate 32, and the cover piece 41 is connected to the front end of the top plate 40. The top plate side piece 42 has a roughly rectangular shape and is connected to both ends of the top plate 40 in the left-right direction X. The cover side piece 43 has a roughly rectangular shape and is connected to both ends of the cover piece 41 in the left-right direction X. The opening piece 44 is formed in a strip shape and is detachably connected to the tip of the cover piece 41. A connecting line (cutting line) P1 is formed between the cover piece 41 and the opening piece 44. The cutting line P1 is curved convexly towards the opening piece 44 at its center in the left-right direction X, and both sides are curved convexly towards the cover piece 41. That is, the cutting line P1 is formed in a roughly M shape.
[0027] As shown in Figures 1 to 3, the top plate 40 extends from the upper end of the rear plate 32 toward the front plate 30, covering the upper surface of the storage section 20 and closing the opening 20a when the lid 21 is closed. The cover piece 41 extends from the front end of the top plate 40 toward the front plate 30. The cover piece 41 has a smaller vertical width than the front plate 30 and is configured to cover the upper area of the front plate 30 when the lid 21 is closed. As shown in Figures 2 and 3, the cover side piece 43 is folded inward of the top plate side piece 42 and covers the inner surface of the top plate side piece 42. Preferably, the top plate side piece 42 has an area that covers at least the upper half of the side plate 34 of the storage section 20.
[0028] As shown in Figure 5, the tip of the cover piece 41 is provided with a cutting blade 50 for cutting the film F pulled out from the winding body 11 in the storage section 20. The cutting blade 50 is formed, for example, in the shape of a saw blade. The cutting blade 50 has a thin plate shape, such as metal, resin, or vulcanized fiber, and is attached to the back surface of the tip of the cover piece 41. The shape of the cutting blade 50 can be, for example, straight, V-shaped, or arched. The cutting blade 50 may also be positioned on the ridge between the bottom plate 31 and the front plate 30.
[0029] As shown in Figure 3, the winding body 11 has a cylindrical core 12, and the film F is wound around the core 12. The core 12 can be made of paper or plastic, for example, having a length approximately the same as the length in the left-right direction X inside the winding body housing box 10. The winding body 11 may also be a so-called coreless type (one that does not have a core 12). The film F in this embodiment is a so-called wrap film (for example, a vinylidene chloride-based film, a polyethylene film, etc.). Note that the film F is not limited to wrap film for food packaging, but may also be aluminum foil, cooking sheet, etc.
[0030] As shown in Figure 6, a ridge line A is provided between the rear plate 32 and the lid plate 40 of the winding body storage box 10. As shown in Figure 4, the ridge line A includes a first line A1 that is offset from a virtual straight line B formed by linearly connecting both ends Ae in the left-right direction X of the ridge line A, toward at least one of the rear plate 32 side or the lid plate 40 side, and a second line A2 connected to both sides of the first line A1.
[0031] As shown in Figures 4 and 6, the first line A1 has, for example, a curved shape. The first line A1 is located in the center of the ridge line A in the left-right direction (extension direction) X. The first line A1 has a first curved portion 60 that curves convexly toward the top plate 40 side, and a second curved portion 61 connected to both ends of the first curved portion 60 and curved convexly toward the rear plate 32 side. The first curved portion 60 is located in the center of the first line A1. The first line A1 has a wave-like shape overall. The curve of the first line A1 includes not only smoothly curving lines, but also lines that curve overall by connecting multiple straight lines of different directions. The second line A2 has, for example, a straight shape. The second line A2 is connected to the outer ends of each second curved portion 61 of the first line A1. The second line A2 may also have a curved shape.
[0032] As shown in Figures 1, 4, and 6, the surfaces of the rear plate 32 and the top plate 40 located on both sides of the first line A1 are provided with multiple rectangular regions SA having a specific area (for example, 40 mm × 100 mm) (hereinafter referred to as "specific regions"). Each specific region SA has an adjacent non-slip region SA1 having a first coefficient of dynamic friction and a slippery region SA2 having a second coefficient of dynamic friction.
[0033] In this embodiment, an example is shown in which two specific areas SA are provided on both the rear plate 32 and the top plate 40. However, it is also possible to provide one specific area SA on both the rear plate 32 and the top plate 40. Furthermore, the position in which the specific areas SA are provided is not particularly limited. That is, as in this embodiment, specific areas SA can be provided at both ends in the longitudinal direction of the rear plate 32 (top plate 40), or they can be provided approximately in the center in the longitudinal direction of the rear plate 32 (top plate 40).
[0034] The first dynamic friction coefficient of the non-slip region SA1 is set to be between 0.30 and 0.70. Because the first dynamic friction coefficient is set within this specific range (between 0.30 and 0.70), it provides adequate grip without compromising the feel of holding it. If the first dynamic friction coefficient is less than 0.30, the grip will be poor, and if it exceeds 0.70, it will feel sticky and uncomfortable to hold, and the slipperiness will worsen, reducing productivity; therefore, neither is desirable. Furthermore, it is preferable that the area of the non-slip region SA1 be 85% or less of the area of the specific region SA. This is because if the area of the non-slip region SA1 within the specific region SA is too large (exceeding 85%), the slipperiness will worsen and productivity will decrease.
[0035] The second dynamic friction coefficient in the slippery region SA2 is set to be between 0.3 and 0.7 times the first dynamic friction coefficient. Because the second dynamic friction coefficient is set within this specific range (between 0.3 and 0.7 times the first dynamic friction coefficient), the user's fingers can be guided appropriately into the non-slippery region. If the second dynamic friction coefficient exceeds 0.7 times the first dynamic friction coefficient, the user's fingers will not be able to slip easily, and if the second dynamic friction coefficient is less than 0.3 times the first dynamic friction coefficient, the user's fingers will slip too much, making it difficult to hold, so neither is desirable.
[0036] By applying varnish to the non-slip region SA1 and the slippery region SA2, the surface irregularities can be altered to create their respective coefficients of dynamic friction. By creating these coefficients of dynamic friction through varnish application, multiple protrusions can be formed in each of the non-slip region SA1 and the slippery region SA2. In this case, the unit area (1 cm²) of the non-slip region SA1... 2 The number of protrusions per unit area (1 cm²) in the smooth region SA2. 2The difference between the number of protrusions per touch and the non-slip area SA1 is set to 50-600. This has the advantage that the non-slip area SA1 becomes easier to recognize, and the user will grip it unconsciously. If the difference between the two is too small (less than 50), the non-slip area SA1 becomes difficult to recognize, and if the difference between the two is too large (more than 600), the difference in tactile sensation between the slippery area SA2 and the non-slip area SA1 becomes large, making the user feel uncomfortable, so neither is desirable.
[0037] When applying varnish to the non-slip region SA1 and the slippery region SA2 to achieve their respective coefficients of dynamic friction, the application area of the varnish (non-slip varnish) to the non-slip region SA1 should be set to 10-50% of the area of the specific region SA. This makes it easier to grip without impairing productivity. If the application area of the non-slip varnish is too small (less than 10% of the area of the specific region SA), it becomes difficult to grip, and if the application area of the non-slip varnish is too large (more than 50% of the area of the specific region SA), the slipperiness in the manufacturing process of the storage box deteriorates, reducing productivity, so neither is desirable.
[0038] In this embodiment, an example is shown in which a non-slip region SA1 and a sliding region SA2 are provided in specific areas SA on the surfaces of the rear plate 32 of the storage box 20 and the top plate 40 of the lid portion 21. However, the non-slip region and the sliding region can also be provided in specific areas on the surface of either the rear plate 32 or the top plate 40. Alternatively, instead of (or in addition to) the rear plate 32 and the top plate 40, the non-slip region and the sliding region can also be provided in specific areas on the surface of the bottom plate 31 of the storage box 20 and / or the lid cover piece 41 of the lid portion 21. The storage portion 20 only needs to have at least a front plate, bottom plate, rear plate and side plates, and the lid portion 21 only needs to have at least a top plate and a lid cover piece. The film F is not limited to food packaging wrap film, but may also be aluminum foil, cooking sheet, etc.
[0039] In the winding body storage box 10 according to the embodiment described above, a non-slip region SA1 with a relatively large coefficient of dynamic friction and a slippery region SA2 with a relatively small coefficient of dynamic friction are formed adjacent to each other in a specific region SA on the surface of the rear plate 32 of the storage section 20 and the top plate 40 of the lid section 21. Therefore, when a user holds the winding body storage box 1 in their hand, the user's fingers are naturally guided from the slippery region SA2 to the non-slip region SA1, which has the advantage of providing a good grip and making it less likely to slip.
[0040] Furthermore, in the winding body housing box 10 according to the embodiment described above, Spc(1cm) in the non-slip region SA1 2 Because the difference between the number of protrusions (where contact occurs) and Spc in the slippery area SA2 is set within a specific range (50-600), the non-slippery area SA1 becomes easier to recognize, which has the advantage of allowing the user to grip it unconsciously.
[0041] Furthermore, in the winding body storage box 10 according to the embodiment described above, when different types of varnish are applied to the non-slip region SA1 and the slippery region SA2 to produce their respective coefficients of dynamic friction, the application area of the non-slip varnish in the non-slip region SA1 is set within a specific range (10 to 50% of the area of the specific region SA), which makes it easier to grip without impairing productivity. [Examples]
[0042] Next, examples and comparative examples of the present invention will be described using Tables 1 to 3 and Figures 7 to 8.
[0043] [Method for measuring the coefficient of dynamic friction] The first and second dynamic friction coefficients in each example and comparative example were measured using a Trinity Labs friction measuring instrument "TL201Tt". As the tactile contactor, a Trinity Labs finger model, purchased within one year and free from dirt and wear, was used, processed to have a contact area of 3 mm x 3 mm. As a measurement sample, a sample piece measuring 30 mm x 50 mm with a length of 50 mm in the measurement direction was cut and fixed to a SUS plate, and then the SUS plate was fixed to the table surface of the friction measuring instrument. At this time, the surface layer (the layer formed using each coater varnish) side was set up as the measurement surface. The tactile contactor was placed on the surface of the measurement area of the sample piece with a load of 20 g and moved 40 mm at 10 mm / sec to measure the friction force between the friction adjustment area and the tactile contactor. The maximum load when the tactile contactor started to move was taken as the static friction force, and the static friction coefficient was calculated by dividing this by the load of 20 g. Excluding the peak portion of the static friction force, the average load from the start of relative shearing motion between the contact surfaces up to 30 mm was used as the kinetic friction force, and the coefficient of kinetic friction was calculated by dividing this by the load of 20 g. Measurements were performed in an atmosphere of 23°C and 50% RH. A total of five measurements were taken with different samples, and the arithmetic mean of the five measurements was used as the measured value. If it was not possible to cut the sample to a length of 50 mm in the measurement direction or to measure a length of 30 mm, the length was adjusted accordingly. In such cases, the coefficient of kinetic friction was calculated by excluding the peak portion of the static friction force, using the average load from the start of relative shearing motion between the contact surfaces up to the point where the friction force in the measurement area was obtained as the kinetic friction force, and dividing this by the load of 20 g.
[0044] [Method for measuring Spc] For each example and comparative example, the Spc values were measured using the Mitutoyo Corporation's CNC surface roughness measuring instrument "SURFTEST Extreme SV-3000 CNC," and the results were analyzed using the analysis software "FORMTRACEPAPRO (Formtracepak for Windows version 6.002)." Specifically, first, the sample was placed on a glass plate using double-sided tape that does not affect the surface shape of the sample, so that the surface layer of the sample (the layer formed using each coater varnish) was the measurement surface. Next, measurements were taken using a standard stylus (tip radius 10 μm) with 101 measurement points, a measurement length of 10 mm, a measurement pitch of 100 μm, a range of 800 μm, a 3D measurement pitch of 100 μm, a measurement speed of 1.0 mm / sec, and a return speed of 5 mm / s. Using analysis software, plane correction, a set of band undulation curves (filter type: GAUSSIAN, X-direction high-frequency cutoff 0.200mm, X-direction low-frequency cutoff 2.000mm, Y-direction high-frequency cutoff 0.200mm, Y-direction low-frequency cutoff 2.000mm), and a peak setting of 0.002mm were performed. Average plane correction and automatic generation of lead-up and trailing curves were then performed to measure a 10mm x 10mm area, and the number of convex areas (Spc) was obtained. If it was not possible to measure the 10mm x 10mm area, the measurement result obtained by converting the measurement result of a measurable area to 10mm x 10mm was used.
[0045] [Grip] The grip properties of the samples in each example and comparative example were evaluated by sensory evaluation as follows. Specifically, 100 subjects were asked to rate the grip properties of the winding material storage box 10 for each sample on a 5-point scale: "5: Very good," "4: Good," "3: Average," "2: Poor," and "1: Very poor." Based on the average score obtained, the evaluation was made as follows. • Average score between 4.5 and 5.0: "◎" (Excellent) • Average score between 3.5 and 4.5: "〇" (Excellent) • Average score between 2.5 and 3.5: "△" (Average) • Average score between 1.5 and 2.5: "×" (inferior) • Average score between 1 and 1.5: "XX" (significantly inferior)
[0046] [Productivity (Defect Rate)] Regarding the productivity of samples for each example and comparative example, 1000 prototypes were made, and the samples were checked after being sack-bonded using a sack machine. The percentage of samples that were not folded along the crease lines was defined as the defect rate and evaluated as follows. 0-2%: "〇" 3-5%: "△" • 6% or more: "×"
[0047] <Example 1> Basis weight 550g / m 2 A coiled material storage box 10 was made using coated cardboard (Suncoat manufactured by Oji Material) as the base material. Then, as shown in the bottom row of Figure 7, 40 mm × 100 mm (area 4000 mm) 2 Within a rectangular specific region SA, nine 3mm x 40mm strip-shaped non-slip regions SA1 were arranged at regular intervals to form a surface. At this time, the areas within the specific region SA excluding the areas where the non-slip regions SA1 were to be formed (i.e., the slippery regions SA2) were masked with masking tape, and coater varnish 1 (see Table 1) was applied to the substrate to a thickness of 10 μm. After that, the surface was quickly irradiated with a 160 W / cm high-pressure mercury UV lamp to UV cure it, thereby forming the non-slip regions SA1 (coater varnish 1 corresponds to the so-called "non-slip varnish"). After this, the masking tape was removed, and the uncoated areas of the non-slip regions SA1 (the areas that form the slippery regions SA2) were exposed to form the slippery regions SA2. At this time, the non-slip regions SA1 within the specific region SA were masked with masking tape, and an underprint UV ink was applied to the substrate to a thickness of approximately 1 μm. The underprint ink layer was then formed by irradiating it with a 160 W / cm high-pressure mercury UV lamp to UV cure it. Toyo Ink's FD HS peel-off OP varnish was used as the material for forming the underprint ink layer (see Table 2).
