The back panel side pieces 35 have a square shape and are connected to both ends of the back panel 32 in the left-right direction X. The back panel side pieces 37 are connected to both ends of the back panel 36 in the left-right direction X.

[0018] The front plate 30 has a wavy cut 30a formed along both ends in the left-right direction X. A temporary fastening member Q for temporarily fastening an end of the film F is provided on the surface of the front plate 30. The back plate 36 has a cut 36a formed therein, which is connected to a connection line (fold line) between the back plate 36 and the front plate 30.

[0019] As shown in FIG. 3, the storage section 20 is formed in a rectangular parallelepiped shape with an open top. The front plate 30, the bottom plate 31, the rear plate 32, and the side plate 34 constitute five walls of the storage section 20 other than the top surface. The back plate 36 is folded back inside the front plate 30 and disposed on the back surface of the front plate 30. The upper part of the front plate 30 above the cut 30a is separated from the lower part and rises forward. The upper part of the back plate 36 above the cut 36a is separated from the lower part and rises backward. The rear plate side piece 35 is folded back inside the side plate 34 to cover the inner surface of the side plate 34. The front plate side piece 33 and the rear plate side piece 37 are folded back to the inner surface of the side plate 34 and are interposed between the rear plate side piece 35 and the side plate 34.

[0020] As shown in the development view of FIG. 4, the lid portion 21 has a lid plate 40, a cover piece 41, a lid plate side piece 42, a cover side piece 43, an opening piece 44, and the like.

[0021] The cover plate 40 and the cover piece 41 have a rectangular shape that is long 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 cover plate side pieces 42 have a rectangular shape and are connected to both ends of the cover plate 40 in the left-right direction X. The cover side pieces 43 have a rectangular shape and are connected to both ends of the cover piece 41 in the left-right direction X. The opening piece 44 is formed in a belt shape and is connected to the tip of the cover piece 41 so that it can be cut off. A connection line (cutting line) P1 is formed between the cover piece 41 and the opening piece 44. The center of the cutting line P1 in the left-right direction X is curved convexly toward the opening piece 44 side, and both sides are curved convexly toward the cover piece 41 side. That is, the cutting line P1 is formed in a substantially M-shape.

[0022] The cover plate 40 extends from the upper end of the rear plate 32 toward the front plate 30 as shown in Fig. 3, and covers the upper surface of the storage section 20 and closes the opening when the lid part 21 is closed as shown in Fig. 1. The cover piece 41 extends from the front end of the cover plate 40 toward the front plate 30. The cover piece 41 has a vertical width smaller than that of the front plate 30, and is configured to cover the upper region of the front plate 30 when the lid part 21 is closed. As shown in Fig. 3, the cover side piece 43 is folded back inside the cover plate side piece 42 and covers the inner surface of the cover plate side piece 42.

[0023] 5 is a front view of the roll storage box 10 with the opening piece 44 cut away. As shown in FIG. 5, a cutting blade 50 is provided at the tip of the cover piece 41 to cut the film F pulled out from the roll 11 in the storage section 20.

[0024] The cutting blade 50 is formed, for example, in a saw blade shape. The cutting blade 50 has a thin plate shape made of, for example, metal, resin, vulcanized fiber, or the like, and is attached to the back surface of the tip of the cover piece 41. The shape of the cutting blade 50 is a conventionally known shape, such as a straight line, a V-shape, an arch shape, or the like. The cutting blade 50 may also be disposed on the ridge between the bottom plate 31 and the front plate 30.

[0025] Fig. 6 is a vertical cross-sectional view for explaining an example of the internal configuration of the wound body storage box 10. Fig. 6 is a vertical cross-sectional view of the wound body storage box 10 cut along a plane along the left-right direction X. Fig. 7 is a top view showing an example of the internal configuration of the wound body storage box 10.

[0026] The rolled body storage box 10 has an upward protruding portion 80 that protrudes upward on the bottom plate 31. The upward protruding portion 80 has a support surface 90 that supports the rolled body 11. The support surface 90 of the upward protruding portion 80 is arranged above the upper surface 31a of the bottom plate 31 and is configured to support both ends in the left-right direction X of the file F of the rolled body 11. The support surface 90 may be a flat surface. The upward protruding portion 80 is arranged at two locations, near one end and near the other end of the bottom plate 31 in the left-right direction X.

[0027] 7, each upper protrusion 80 has an elongated convex shape extending in the front-to-rear direction Y of the bottom plate 31. Each upper protrusion 80 is configured so as to leave a gap between it and the front plate 30 and between it and the rear plate 32. In other words, each upper protrusion 80 has a length smaller than the width of the bottom plate 31 in the front-to-rear direction Y, and is disposed near the center of the bottom plate 31 in the front-to-rear direction Y.

[0028] The upward protrusion 80 may have a vertical length of 0.5 mm to 3.0 mm, preferably 0.5 mm to 1.0 mm. The thickness of the bottom plate 31 may be 0.3 mm to 1.0 mm. As shown in FIG. 8, the wound body storage box 10 is configured such that a vertical distance L1 from a support surface 90 that supports the wound body 11 to a ground surface 100 of the wound body storage box 10 is greater than a thickness L2 of the bottom plate 31. In this embodiment, the ground surface 100 of the wound body storage box 10 may be the lower surface 31b of the bottom plate 31.

[0029] For example, the upward protrusion 80 may be formed of a member separate from the integral paper that constitutes the roll storage box 10. The upward protrusion 80 may be formed of an embossment formed by varnish applied to the bottom plate 31.

[0030] The upward protruding portion 80 is formed from a single piece of paper that constitutes the roll storage box 10. In this case, as shown in Fig. 9, the upward protruding portion 80 may be formed by the paper plate of the bottom plate 31 being recessed upward.

[0031] According to this embodiment, the wound body storage box 10 is configured so that the vertical distance L1 from the support surface 90 that supports the wound body 11 to the ground surface 100 of the wound body storage box 10 is greater than the thickness L2 of the bottom plate 31. This makes it possible to prevent the film F of the wound body 11 stored in the wound body storage box 10 from being affected by heat transferred from the installation surface of the box.

[0032] The support surface 90 is disposed above the upper surface 31a of the bottom plate 31 and is configured to support both ends of the film F of the roll 11 in the longitudinal direction. Since both ends of the film F in the longitudinal direction have the side surfaces of the film F, heat is less likely to accumulate and is easily dissipated. By the support surface 90 supporting both ends of the film F, heat transferred from the installation surface of the box is easily dissipated. As a result, it is possible to suppress the film F from being affected by heat. In addition, the core 12 constituting the roll 11 is configured to be shorter than the inner dimension of the roll storage box 10 in order to suppress interference with the inside of the roll storage box 10 and facilitate the drawing out of the film. For this reason, the core 12 may move slightly in the left-right direction X in the roll storage box due to vibrations, etc., and depending on the arrangement of the support surface 90, one side of the roll 11 may come into contact with the installation surface and be affected by heat. Therefore, by configuring the support surface 90 to support both ends of the film and also taking into account the movement of the core 12, it is possible to effectively suppress the influence of heat.

[0033] The bottom plate 31 has an upward protruding portion 80 that protrudes upward, and the upward protruding portion 80 has a support surface 90, so that the position of the support surface 90 can be suitably raised.

[0034] The upper protrusion 80 has a ridge shape extending in the front-rear direction Y of the bottom plate 31. This makes it possible to reduce the contact area between the film F and the support surface 90 of the upper protrusion 80, thereby suppressing the film F from being affected by heat from the installation surface of the box.

[0035] The upward protrusion 80 is configured to provide a gap between the upward protrusion 80 and the front plate 30 and between the upward protrusion 80 and the rear plate 32. This prevents heat from being transferred from the installation surface of the box to the film F through the front plate 30 or the rear plate 32. As a result, the film F can be prevented from being affected by the heat of the installation surface of the box.

[0036] The upward protrusions 80 are disposed at a plurality of locations on the bottom plate 31. This allows the wound body 11 to be stably supported.

[0037] The upward protruding portion 80 is made of a single piece of paper that constitutes the wound body storage box 10. This makes it possible to easily form the wound body storage box 10 having the upward protruding portion 80.

[0038] In this embodiment, the support surface 90 of the upward protrusion 80 may have a shape that is curved in an arc shape convex upward, as shown in Fig. 10. In this case, the contact area between the film F and the support surface 90 can be reduced, and as a result, the film F can be prevented from being affected by the heat of the installation surface of the box.

[0039] (Second embodiment) Fig. 11 is a perspective view showing an example of the wound body storage box 10 in the present embodiment. Fig. 12 is a vertical cross-sectional view for explaining an example of the configuration of the wound body storage box 10. Fig. 12 is a vertical cross-sectional view of the wound body storage box 10 cut along a surface along the left-right direction X. Fig. 13 is a bottom view showing an example of the configuration of the wound body storage box 10.

[0040] 11 and 12, in this embodiment, the wound body storage box 10 has a downward protruding portion 120 that protrudes downward from the bottom plate 31. The downward protruding portion 120 has a ground surface 100 on its lower surface. The ground surface 100 of the wound body storage box 10 is disposed below the lower surface 31b of the bottom plate 31. The ground surface 100 may be a flat surface.

[0041] The downward protrusions 120 are disposed in regions on both sides of the center of the bottom plate 31 in the left-right direction X. The downward protrusions 120 are disposed in two locations on the bottom plate 31. As shown in Figs. 12 and 13, the downward protrusions 120 are disposed at both ends of the bottom plate 31 in the left-right direction X. The downward protrusions 120 have an elongated convex shape extending in the front-rear direction Y of the bottom plate 31. The downward protrusions 120 may have a length equal to the width of the bottom plate 31 in the front-rear direction Y. The downward protrusions 120 may have a length smaller than the width of the bottom plate 31 in the front-rear direction Y. Note that a plurality of downward protrusions 120 may be disposed along the front-rear direction Y of the bottom plate 31.

[0042] The downward protrusion 120 may have a vertical length of 0.5 mm to 3.0 mm, preferably 0.5 mm to 1.0 mm. The thickness of the bottom plate 31 may be 0.3 mm to 1.0 mm. As shown in FIG. 14, the wound body storage box 10 is configured such that a vertical distance L1 from a support surface 90 that supports the wound body 11 to a ground surface 100 of the wound body storage box 10 is greater than a thickness L2 of the bottom plate 31. The support surface 90 may be an upper surface 31a of the bottom plate 31. The support surface 90 may be an upper surface of the upward protrusion 80, as in the first embodiment.

[0043] For example, the downward protrusion 120 may be formed of a member separate from the integral paper that constitutes the roll storage box 10. The downward protrusion 120 may be formed of an embossment formed by varnish applied to the lower surface 31b of the bottom plate 31.

[0044] The downward protrusion 120 may be formed of an integral piece of paper that constitutes the wound body storage box 10. In this case, as shown in Fig. 15, the downward protrusion 120 may be formed by the paper of the bottom plate 31 being recessed downward. Other configurations of the wound body storage device 1 in this embodiment may be the same as the configurations of the wound body storage device 1 in the above-mentioned first embodiment.

[0045] According to this embodiment, the ground surface 100 is disposed below the lower surface 31b of the bottom plate 31. This makes it possible to prevent the film F of the roll 11 accommodated in the roll-containing box 10 from being affected by heat transferred from the installation surface of the box.

[0046] The bottom plate 31 has a downward protruding portion 120 that protrudes downward, and the downward protruding portion 120 has the ground contact surface 100, so that the position of the ground contact surface 100 can be suitably lowered.

[0047] The downward protrusions 120 are disposed at both ends of the bottom plate 31 in the left-right direction X. This allows the film F of the roll 11 accommodated in the roll-containing box 10 to be separated from the downward protrusions 120, thereby preventing the film F from being affected by heat from the installation surface of the box.

[0048] The downward protrusion 120 has a convex shape extending in the front-rear direction Y of the bottom plate 31. This makes it possible to reduce the contact area between the ground surface 100 of the downward protrusion 120 and the installation surface of the box, thereby making it possible to suppress the film F from being affected by heat from the installation surface of the box.

[0049] The downward protrusions 120 are disposed at a plurality of positions on the bottom plate 31. This allows the wound body storage box 10 to be stably placed thereon.

[0050] The downward protruding portion 120 is made of a single piece of paper that constitutes the wound body storage box 10. This makes it possible to easily form the wound body storage box 10 having the downward protruding portion 120.

[0051] 16, the contact surface 100 of the downward protrusion 120 may have a shape that is curved in a convex arc shape downward. In this case, the contact area between the contact surface 100 of the box and the ground can be reduced, and as a result, the film F can be prevented from being affected by heat from the installation surface of the box.

[0052] 17, in the second embodiment, the downward protrusions 120 may be disposed on the inner side (toward the center) of both ends in the left-right direction X of the bottom plate 31. The downward protrusions 120 are disposed in regions on both sides of the center of the bottom plate 31 in the left-right direction X.

[0053] In the second embodiment, as shown in Fig. 18 to Fig. 20, the downward protrusions 120 may be disposed in regions on both sides of the center of the bottom plate 31 in the front-rear direction Y. Fig. 18 is a perspective view for explaining an example of such a wound body storage box 10. Fig. 19 is a vertical cross-sectional view for explaining a configuration example of the wound body storage box 10. Fig. 19 is a vertical cross-sectional view of the wound body storage box 10 cut along a plane along the front-rear direction Y. Fig. 20 is a bottom view of the wound body storage box 10.

[0054] The downward protrusions 120 are disposed at both ends of the bottom plate 31 in the front-rear direction Y. The downward protrusions 120 have an elongated convex shape extending in the left-right direction X of the bottom plate 31. The downward protrusions 120 may have a length equal to the width of the bottom plate 31 in the left-right direction X. The downward protrusions 120 may have a length smaller than the width of the bottom plate 31 in the left-right direction X. Note that a plurality of downward protrusions 120 may be disposed along the left-right direction X of the bottom plate 31.

[0055] The downward protrusion 120 may be disposed on the inner side (toward the center) of both ends in the front-rear direction Y of the bottom plate 31.

[0056] The downward protrusions 120 may be disposed at both ends of the bottom plate 31 in the left-right direction X and at both ends of the bottom plate 31 in the front-rear direction Y.

[0057] The above embodiments are described for the purpose of explanation and are not intended to limit the scope of the present disclosure. Various modifications can be made to the above embodiments without departing from the scope and spirit of the present disclosure. For example, some components in one embodiment can be added to other embodiments. Also, some components in one embodiment can be replaced with corresponding components in other embodiments.
