Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the rewinding prevention means as described above, if the locking force is too strong, the film is difficult to peel off or pick up, and in some cases, end face peeling may occur. On the contrary, if the locking force is too weak, there is a concern that the film may rewind.

[0005] Therefore, the present invention aims to provide a rewound film storage box that effectively prevents the film from unwinding while using existing locking means, and improves usability by making the film easier to grasp and peel off. [Means for solving the problem]

[0006] To solve these problems, the inventors conducted various studies. Considering the trade-off between the force that prevents the film from unwinding (in other words, the locking force of varnish, seals, etc., that function as means to hold the film in place) and the ease of use, such as being able to easily grasp and peel off the film during use, it is not easy to actually develop the locking means itself (varnish, seals, etc.) when adjusting the unwinding prevention force. Furthermore, from the standpoint of ease of use, it is important to consider structural characteristics, such as the fact that if the film is peeled from the edge of the winding case (cosmetic box), the grasping position and the peeling position are separated, making edge peeling more likely. Based on the above, the inventors conducted further studies and have come to a conclusion that will lead to the solution of these problems.

[0007] Based on these findings, one aspect of the present invention is a winding body storage box capable of accommodating a winding body on which a film is wound, A storage section capable of accommodating a retracted body, including a front plate, bottom plate, rear plate, and side plates, with an open top surface, The opening on the top surface of the housing can be opened and closed, and the lid portion includes a lid plate and a cover piece, A rewind prevention means that locks and temporarily fastens the end of the film pulled out from the winding body, thereby preventing the film from rewinding towards the storage section, It is equipped with, The rewinding prevention means is a rewinding container in which a locking portion for securing the film and a non-locking portion occupying the portion other than the locking portion are alternately arranged at specific locations of the rewinding prevention means in a manner that forms a predetermined pattern.

[0008] In such a rewound body storage box, the rewind prevention means is formed by a locking portion that secures the film and a non-locking portion that occupies the portion other than the locking portion. Therefore, without adjusting the locking force of the locking means itself (varnish, seal, etc.), the locking force of the film in the rewind prevention means, and thus the rewind prevention force, can be adjusted by changing the arrangement and distribution of the locking portion and the non-locking portion.

[0009] In the winding body housing box described above, the locking portion and the non-locking portion may be arranged symmetrically around a specific point.

[0010] In the above-described reel storage box, a specific location may be intended to guide the user's finger when attempting to peel off the film that has been locked to the locking part of the rewinding prevention means.

[0011] In the winding material storage box described above, the specific location may be approximately the center in the longitudinal direction of the winding material storage box.

[0012] In the above-described winding housing box, the locking portion and the non-locking portion may be formed in a strip shape.

[0013] In the winding body housing box described above, the non-locking portion may be formed to have a constant width in the longitudinal direction of the winding body housing box.

[0014] In the above-described winding housing box, the width of the non-locking portion in the longitudinal direction of the winding housing box may be 2 mm or less.

[0015] In the winding body housing box described above, the non-locking portion may be inclined with respect to a reference line along the longitudinal direction of the winding body housing box.

[0016] In the above-described winding housing box, the non-locking portion may be formed in a stripe pattern.

[0017] In the wound body storage box as described above, the inclination angle of the non-locking portion with respect to the reference line may be 60° or more on the acute angle side.

[0018] In the wound body storage box as described above, the inclination angle of the non-locking portion with respect to the reference line may be 65° to 75° on the acute angle side.

[0019] In the wound body storage box as described above, the non-locking portion may be formed radially around a specific location.

[0020] In the wound body storage box as described above, the minimum inclination angle of the non-locking portion with respect to the reference line along the longitudinal direction of the wound body storage box may be 70° or more.

[0021] In the wound body storage box as described above, the area of the locking portion may be 2 / 3 or more in the area of the rewinding prevention means.

[0022] In the wound body storage box as described above, the rewinding prevention means may be formed by alternately arranging the locking portion and the non-locking portion in a pattern that can be visually recognized.

Effect of the Invention

[0023] According to the present invention, it is possible to provide a wound body storage box that充分发挥 the rewinding prevention force of the film while using existing locking means, and that makes it easy to pick up and peel off the film, improving the usability.

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.

[0033] As shown in Figure 3, the storage compartment 20 is formed in the shape of a rectangular parallelepiped with an open top. The front plate 30, bottom plate 31, rear plate 32, and side plates 34 constitute the five wall surfaces of the storage compartment 20 other than the top surface. 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, separated from the lower part. The part of the back plate 36 above the notch 36a is raised backward, separated 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.

[0034] As shown in the unfolded view of Figure 4, the lid portion 21 includes a lid plate 40, a cover piece 41, a side piece 42 of the lid plate, a side piece 43 of the cover piece, and an opening piece 44, etc.

[0035] The cover plate 40 and the cover piece 41 have a rectangular shape that is elongated in the left-right direction X, and are connected to each other in the front-rear direction Y. The cover 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 cover plate 40.

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.

[0036] As shown in Figure 3, the lid plate 40 extends from the upper end of the rear plate 32 toward the front plate 30, and as shown in Figure 1, covers the upper surface of the storage section 20 and closes the opening when the lid section 21 is closed. The cover piece 41 extends from the front end of the lid plate 40 toward the front plate 30. The cover piece 41 is smaller in height than the front plate 30 and is configured to cover the upper area of ​​the front plate 30 when the lid section 21 is closed. As shown in Figure 3, the cover side piece 43 is folded inward from the cover side piece 42 and covers the inner surface of the cover side piece 42.

[0037] Figure 5 is a front view of the winding body storage box 10 with the opening piece 44 cut off. 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 inside the storage section 20.

[0038] 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 is conventionally known, such as a straight, V-shaped, or arched shape. The cutting blade 50 may also be positioned on the ridge between the bottom plate 31 and the front plate 30.

[0039] 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.

[0040] 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 cover 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 as a whole has a wave shape. The curve of the first line A1 includes not only smoothly curving lines, but also lines that are curved as a whole by connecting multiple straight lines of different directions.

[0041] The second line A2 has, for example, a straight shape. The second line A2 is connected to the outer end of each second curved portion 61 of the first line A1. The second line A2 may have a curved shape.

[0042] The rear plate 32 and the cover plate 40 located on both sides of the first line A1 have a first coating area 70, a second coating area 71, a third coating area 72, and a fourth coating area 73 on their surfaces.

[0043] The first coating area 70 includes the first line A1 and is provided along the first line A1. The first coating area 70 is provided in a corrugated band shape and has a constant first width D1. The first coating area 70 is provided such that its center line coincides with the first line A1. The first width D1 is preferably 4 mm to 20 mm, more preferably 6 mm to 15 mm. The arithmetic mean height Sa (ISO 25178) of the first coating area 70 is less than 3 μm, more preferably 2 μm or less. The first coating area 70 is formed, for example, by applying a first varnish with high specular gloss. Specular gloss (JIS Z 8741) can be measured by a gloss meter VG8000 (manufactured by Nippon Denshoku Industries Ltd.). The 60-degree specular gloss of the first coating area 70 is preferably 15% or more, and more preferably 20% or more.

[0044] The third coating region 72 includes the second line A2 and is provided along the second line A2. The third coating region 72 is connected to both ends of the first coating region 70. The third coating region 72 is provided in a straight, strip-like shape and has a constant second width D2. The third coating region 72 is provided such that its centerline coincides with the second line A2. The second width D2 is smaller than the first width D1. The second width D2 is preferably 2 mm or more and 10 mm or less, more preferably 3 mm or more and 8 mm or less. The arithmetic mean height Sa (ISO 25178) of the third coating region 72 is less than 3 μm, more preferably 2 μm or less. The third coating region 72 is formed, for example, by applying the first varnish.

[0045] The second coating area 71 is adjacent to the first coating area 70 and spaced apart from the first line A1. The second coating area 71 is spaced at least 2 mm apart from the ridge line A. The second coating area 71 is spaced at least 2 mm apart from the imaginary straight line B. The second coating area 71 is provided on both sides of the first coating area 70, on the rear plate 32 and the cover plate 40, respectively. The second coating area 71 has a substantially rectangular shape on the cover plate 40 and the rear plate 32. The second coating area 71 is provided on both the cover plate 40 and the rear plate 32, extending from near one end to near the other end in the front-rear direction Y. The arithmetic mean height Sa (ISO 25178) of the second coating area 71 is 3 μm or more, more preferably 4 μm or more, and even more preferably 5 μm or more.

[0046] The second coating region 71 has, for example, an embossed region 80 with irregularities. The second coating region 71 is formed, for example, by applying a third varnish with high water repellency on top of the second varnish. For example, the second varnish has a lower gloss than the first varnish. The raised portion of the embossed region 80 of the second coating region 71 has an area of ​​20% or more of the entire embossed region. The raised portion is made up of the third varnish. In the example shown in Figure 7, for example, the lighter colored area is the raised portion made up of the third varnish. The area of ​​the raised portion can be determined using a known method. For example, the height data of the embossed region 80 is binarized using the edge of the raised portion as a threshold, and the area ratio occupied by the raised portion in the plan view of the original data is calculated.

[0047] The embossed area 80 of the second coating area 71 is, for example, Spc is 200 mm -1 500mm or more -1 The following applies, and Spd is 15000mm -2 More than 30000mm -2 It is structured as follows:

[0048] Spd and Spc are surface roughness parameters used to evaluate surface topography and can be measured using a laser microscope (manufactured by Keyence Corporation). Spd is the density (number per unit area) of areas classified as peaks in the shape image created by the laser microscope. Spc is the average value of the radius of curvature of the peaks of areas classified as peaks in the shape image created by the laser microscope. A larger Spc value indicates a smaller (sharper) curvature of the protrusions, while a smaller Spc value indicates a larger (blunter) curvature.

[0049] The following methods were used to measure the arithmetic mean heights Sa, Spd, and Spc using a laser microscope.

[0050] The surface roughness of the coated region layer was measured using a Keyence VK-X1000 laser microscope. A sample piece was cut from the coated region layer and placed on the stage. A 20x objective lens was selected, and the laser confocal mode, measurement size "standard", measurement quality "high precision", and pitch "0.75 μm" were selected to perform height measurements. If there were protrusions or repeating units, the sample piece was cut so that at least 20 or more of them were within the measurement range, and measurements were performed by bonding the pieces together as needed. After setting a reference plane for the entire image obtained, the arithmetic mean height Sa, Spd, and Spc were calculated using the entire measurement region. A total of five measurements were performed at different measurement locations, and the average of the five measurements was used as the measured value.

[0051] The following method was used to measure the distance between the ridge line and the coating region layer. The first and second plates of the winding material housing box were held so that they were on the same plane, and the distance from the center of the crease line forming the ridge line to the boundary line of the coating region layer in the front-to-back direction (Y) or up-to-down direction (Z) was measured with a ruler. The distance between the ridge line and the coating region layer should be 2 mm or more in part of the boundary line, and preferably 2 mm or more across the entire boundary line.

[0052] As shown in Figures 4 and 6, the second coating region 71 may have non-embossed regions 81 on the lid plate 40 and the rear plate 32. The non-embossed regions 81 are formed linearly along the front-to-back direction Y on the lid plate 40 and the rear plate 32. Multiple non-embossed regions 81 are arranged in the left-to-right direction X. The non-embossed regions 81 are formed across both ends of the second coating region 71 in the front-to-back direction Y on the lid plate 40 and the rear plate 32. For example, the non-embossed regions 81 are formed by applying a third varnish different from the first varnish of the first coating region 70.

[0053] The fourth coating area 73 is adjacent to the third coating area 72 and spaced apart from the second line A2. The fourth coating area 73 is spaced at least 2 mm apart from the edge line A. The fourth coating area 73 is spaced at least 2 mm apart from the imaginary straight line B. The fourth coating area 73 is provided on both sides of the third coating area 72, on the rear plate 32 and the cover plate 40, respectively. The fourth coating area 73 has a roughly rectangular shape on the cover plate 40 and the rear plate 32. The fourth coating area 73 is provided on both the cover plate 40 and the rear plate 32, extending from near one end in the front-rear direction Y to near the other end. The fourth coating area 73 is provided on both the cover plate 40 and the rear plate 32, extending to near the end in the left-right direction X. The arithmetic mean height Sa (ISO 25178) of the fourth coating area 73 is 3 μm or more, more preferably 4 μm or more, and even more preferably 5 μm or more. The fourth coating area 73 has, for example, an embossed area with irregularities. The fourth coating area 73 is formed, for example, by applying another varnish on top of a water-repellent varnish. The raised portion of the embossed area of ​​the fourth coating area 73 has an area of ​​20% or more of the entire embossed area. The fourth coating area 73 has, for example, an Spc of 200 mm -1 500mm or more -1 The following applies, and Spd is 15000mm -2 More than 30000mm -2 The following applies:

[0054] The boundary line C1 between the first coating region 70 and the second coating region 71 has the same shape as the first line A1, i.e., a curved shape. The boundary line C2 between the third coating region 72 and the fourth coating region 73 has the same shape as the second line A2, i.e., a straight shape.

[0055] The second coating area 71 and the fourth coating area 73 are continuous. For example, the second coating area 71 and the fourth coating area 73 may be a single, integrated coating area of ​​the same type. The combined coating area of ​​the second coating area 71 and the fourth coating area 73 has a substantially rectangular shape on the cover plate 40 and the rear plate 32. The combined coating area of ​​the second coating area 71 and the fourth coating area 73 is formed on the cover plate 40 and the rear plate 32, extending from near one end to near the other end in the front-to-back direction Y, and from near one end to near the other end in the left-to-right direction X.

[0056] The combined coating area of ​​the second coating area 71 and the fourth coating area 73 is located on the cover plate 40, spaced apart from the ridge line E1 between the cover plate 40 and the cover piece 41, and from the ridge line E2 between the cover plate 40 and the cover plate side piece 42. In other words, the second coating area 71 and the fourth coating area 73 are not formed near the ridge lines E1 and E2 of the cover plate 40.

[0057] The combined coating area of ​​the second coating area 71 and the fourth coating area 73 is located on the rear plate 32, spaced apart from the ridge line E3 between the rear plate 32 and the bottom plate 31, and from the ridge line E4 between the rear plate 32 and the rear plate side piece 35. In other words, the second coating area 71 and the fourth coating area 73 are not formed near the ridge lines E3 and E4 of the rear plate 32.

[0058] [Second Embodiment] Next, a second embodiment of the rewound body storage box 10, which uses existing viscous materials (varnish, sealant, etc.) as a locking means to sufficiently prevent the film F from unwinding, and improves usability by making the film F easier to grasp and peel off, will be described below (see Figures 11 to 16).

[0059] The basic structure of the winding body storage box 10 in this embodiment is the same as that of the embodiment described above. However, in this embodiment, a rewinding prevention means 90 is provided as a temporary fastening member Q to temporarily fasten the end of the film F pulled out from the winding body 11 and prevent the film F from rewinding back toward the storage section 20. The rewinding prevention means 90 consists of a locking portion 91 and a non-locking portion 92.

[0060] The locking portion 91 is the part that locks a portion of the film F, and the locked portion 92 is the remaining portion. The locking portion 91 is a portion that is attached with an existing viscous material such as varnish or sealant, and when it is arranged next to the non-locking portion 92 which has not been treated with a viscous material, the portion that is the locking portion 91 is formed in a manner that the user can visually recognize as having been treated differently from the non-locking portion 92 (for example, a manner in which the surface is glossy due to the attachment of a viscous material, or a manner in which the portion is colored, etc.) (see Figure 11, etc.).

[0061] In the winding body storage box 10 of this embodiment, the locking portion 91 and the non-locking portion 92 are arranged symmetrically around a specific location C (see Figure 11, etc.). The specific location C here may be, for example, a location intended to guide the user's finger when attempting to peel off the film F that has been locked to the locking portion 91 of the rewinding prevention means 10. In this embodiment, the locking portion 91 and the non-locking portion 92 are arranged symmetrically to the left and right around the approximate center position (see Figures 1 to 6, 8 to 10) in the longitudinal direction (left-right direction X) of the winding body storage box 10 (see Figure 12, etc.). The rewind-preventing means 90 configured in this way is designed so that the user can visually recognize a specific location (in this embodiment, approximately the center of the left-right direction X) C, thereby visually guiding the user who is trying to pull out and use the film F to the part they should pinch with their fingers (the central part of the winding body storage box 10) (see Figure 12, etc.). When the film F is pinched approximately in the center and pulled away from the rewind-preventing means 90, the film F peels away from the locking portion 91 in a concentric pattern starting from that point, and eventually, it is cleanly pulled away from the rewind-preventing means 90 without causing end-face peeling, and can be easily and cleanly pulled out of the winding body storage box 10 (see Figure 12, etc.).

[0062] Furthermore, since the rewind prevention means 90 of this embodiment is formed of a locking portion 91 that locks the film F and a non-locking portion 92 that occupies the portion other than the locking portion 91, the locking force of the film F in the rewind prevention means 90, and thus the rewind prevention force, can be adjusted by changing the arrangement and distribution of the locking portion 91 and the non-locking portion 92, without adjusting the locking force itself (strength of viscosity, magnitude of adhesive force) of the viscous material (varnish, sealant, etc.) that forms the locking means. For this reason, it is possible to freely adjust the magnitude of the locking force while applying existing materials, without using a new viscous material with adjusted viscosity for the locking portion 91. For example, it is preferable that the area of ​​the locking portion 91 is 2 / 3 or more of the total area of ​​the rewind prevention means 90 (in other words, the area of ​​the locking portion 91 is 2 times or more the area of ​​the non-locking portion 92), but of course this is just one example of a suitable ratio (see Figure 15, etc.).

[0063] The specific form of the locking portion 91 and the non-locking portion 92 that occupies the portion other than the locking portion 91 is not particularly limited, but preferred examples are as follows (see Figures 11, 15, etc.). First, the locking portion 91 and the non-locking portion 92 are formed in a strip shape (see Figures 11 and 15(A)). In this case, the non-locking portion 92 may be formed in a stripe shape. Also, the non-locking portion 92 may be formed so that its width in the longitudinal direction (left-right direction X) of the winding body housing box 10 is constant (see Figures 11 and 15(B)). The portion of the film F that is not locked by the locking portion 91 (in other words, the portion that overlaps with the non-locking portion 92) becomes wrinkled or loose, making it easier for the user to grasp with their fingers (see Figure 14). However, if the width of the non-locking portion 92 is too wide, there is a concern that the locking force of the locking portion 91 will decrease. Considering these factors, it is preferable that the width of the non-locking portion 92 along the left-right direction X is 1 / 2 or less of the width of the locking portion 91, or that the width of the non-locking portion 92 along the left-right direction X is, for example, 2 mm or less. However, this is merely a preferred example, and the specific size is not limited. The size of the width can be various values ​​depending on the material of the film F, etc.

[0064] Furthermore, the locking portion 92 may be inclined with respect to a reference line (indicated by the symbol R in Figures 11 and 15) along the longitudinal direction (left-right direction X) of the winding body housing box 10 (see Figures 11 and 15). In this case, the inclination angle θ of the non-locking portion 92 with respect to the reference line R is preferably 60° or more on the acute side, or the minimum inclination angle is 70° or more, preferably 65° to 75°, in terms of ease of peeling the film F. Normally, the direction of peeling when rewinding the film F is linear along the vertical direction Z (see Figure 13). In this respect, if the non-locking portion 92 is inclined with respect to the reference line R as described above, the direction of peeling when rewinding the film F will be different from the direction of peeling when pinching with the thumb, and as a result, it will be easier to maintain the locking strength against the rewinding of the film F (see Figure 13).

[0065] Furthermore, the locking portion 92 may be formed radially around a specific location (in this embodiment, approximately the center of the left-right direction X) C (see Figure 16(A)). Alternatively, the locking portion 92 may be symmetrically arranged in a V-shape such that the inclination angle θ changes with respect to the specific location (in this embodiment, approximately the center of the left-right direction X) C (see Figures 11, 12, etc.). In such cases, it is preferable not only in terms of ease of peeling off the film F, but also in terms of making it easier to visually indicate to the user the part they should pinch with their fingers when peeling off the film F (in this embodiment, approximately the center of the left-right direction X).

[0066] The locking portion 91 and the non-locking portion 92 constituting the unwinding prevention means 90 of the winding material storage box 10 may be in yet another form. For example, either one or both of the locking portion 91 and the non-locking portion 92 may have a tapered shape with uneven width (see Figures 15(C) to (E)). Also, the unwinding prevention means 90 may be formed in a rectangular shape as a whole (see Figure 16(B)), or in any other shape (see Figures 11 to 13).

[0067] As described above, this embodiment makes it possible to realize a rewound body storage box 10 that takes into consideration both the force that prevents the film F from unwinding (in other words, the locking force by the locking part 91 which functions as a means for locking the film) and the ease of use, such as making the film F easy to grasp and peel off when in use. Furthermore, this embodiment of the rewound body storage box 10 also makes it possible to prevent phenomena such as peeling of the film F's edges.

[0068] Preferred embodiments of the present invention have been described above with reference to the attached drawings, but the present invention is not limited to these examples. It will be clear to those skilled in the art that various modifications or alterations can be conceived within the scope of the ideas described in the claims, and these will naturally also fall within the technical scope of the present invention. [Examples]

[0069] The inventors prototyped winding storage boxes 10 having various winding prevention means 90 with different widths for the locking portion 91 and the non-locking portion 92, the inclination angle θ of the non-locking portion 92 with respect to the reference line R, and the specific configuration (hereinafter also referred to as "pattern") of the locking portion 91 and the non-locking portion 92 occupying the portion other than the locking portion 91, and conducted winding tests and sensory tests. The details are described below as examples / comparative examples (see Figure 17). In this example, the "rewinding test" involved pulling out 30 cm of film F from the winding body storage box 10, placing a thumb on the top lid plate 40, closing the lid 21 by pressing with the thumb, cutting the film F with the cutting blade 50, opening the lid 21 with the side piece 42 of the lid plate, and blowing for 10 seconds with a Panasonic hair dryer (EH-NE7L-P, without quick-drying nozzle) from a distance of 30 cm perpendicular to the front plate 30 towards the longitudinal center of the locking means 90. The test was rated as follows: "◎" if film F adhered to the locking part 91 did not peel off; "○" if it peeled off in 2 seconds or more but less than 10 seconds of blowing; "△" if it peeled off in 0 seconds or more but less than 2 seconds of blowing; and "×" if it peeled off when the lid was opened (see Figure 17).

[0070] Furthermore, the "sensory evaluation (ease of picking)" in this example involved having 100 subjects perform the action of picking up the wrap film F 10 times each using prototypes coated with various shapes of varnish in a cosmetic box with the structure shown in Figure 2. They were then asked to rate the ease of picking up the film F in the rolled-up body container box 10 during the series of actions on a three-point scale: "easy to pick up," "average," and "difficult to pick up." In this example, based on the results of this evaluation, the number of "easy to pick up" responses was counted, and if there were 50 or more responses, it was marked as "◎," if there were 35 or more, it was marked as "○," if there were 25 or more, it was marked as "△," and if there were fewer than 25, it was marked as "×" (see Figure 17).

[0071] Furthermore, in this example, the "sensory evaluation (pinching guidance)" involved showing the front plate portion 30 (locking portion 91) of the above prototype to 100 subjects for 2 seconds, then handing it to them and having them perform a pinching motion on the wrap film F. The subjects were then evaluated on a 3-point scale whether their thumbs were guided before they were able to pull out the film F, which was locked to the locking portion 91 of the rewinding prevention means 10. In this example, based on the results of this evaluation, the number of times the film F could be pulled out by pinching the central part (a range of 5 mm to the left and right of the imaginary line in the longitudinal center of the rewound body housing cosmetic box 10 or the specific location C mentioned above) was counted. If the number was 90 or more, it was marked "◎", if it was 80 or more, it was marked "○", if it was 70 or more, it was marked "△", and if it was less than 70, it was marked "×" (see Figure 17).
