Description

[Technical Field]

[0001] The present invention relates to an item storage box in which a plurality of items are stored in a stacked state. [Background technology]

[0002] An example of a conventional item storage box is the tissue paper carton described in Patent Document 1. The item storage box described in this document has a box-shaped main body (tissue paper carton main body) and stores a plurality of items (tissue paper) stacked on top of each other. The top surface (top plate) of the main body has a take-out opening forming section (tissue paper take-out opening) at its center, which is used to form an opening for taking out the items. The take-out opening forming section has wavy perforations formed along a center line that divides the top surface in half in the short direction.

[0003] In this storage box, after making a cut along the perforation, the sections on either side of the cut (the folding pieces) are folded diagonally upward to form a gap between the folding pieces that serves as the access opening. However, if the folding angle of the folding pieces is small and the gap between the folding pieces is too narrow, the friction between the folding pieces and the item increases (resulting in a large amount of paper dust generated by the tissue paper), and if the folding angle of the folding pieces is large and the gap between the folding pieces is too wide, dust can easily enter the main body through the access opening.

[0004] On the other hand, examples of storage boxes in which the access opening is formed on the side or front part of the main body rather than on the top part include the kitchen paper storage box described in Patent Document 2, the sanitary paper storage box described in Patent Document 3, and the paper storage box described in Patent Document 4. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 9-150871 [Patent Document 2] Japanese Patent Application Laid-Open No. 2011-73704 [Patent Document 3] Japanese Patent Application Laid-Open No. 2013-75681 [Patent Document 4] Japanese Patent Application Laid-Open No. 2016-30608 Summary of the Invention [Problem to be solved by the invention]

[0006] In the storage boxes described in Patent Documents 2 to 4, it is easier to prevent dust from entering the main body than when the access opening is formed on the top surface, but when the access opening (access opening) is formed in the vertical center of the side portion (side surface) of the main body (box portion) as in the storage box described in Patent Document 2, when the stored items (kitchen paper that is folded and stacked in a pop-up format) are stacked up to the top inside the main body, it becomes difficult to remove the items at the top.

[0007] On the other hand, in the item storage box described in Patent Document 3, a contour cut line is provided at the top (directly below the fold line between the front panel and top panel) of the front part (front panel) of the main body (box body), and an access opening (removal port) is formed by cutting along the contour cut line, but at this time, the lid, which has a contour shape that follows the contour cut line, covers from above the part of the item (sanitary paper that is alternately folded and stacked so that it can be removed in a pop-up manner) that is pulled out of the access opening, causing the problem that the item is difficult to remove unless it is pulled out toward the bottom front side of the item storage box.

[0008] Furthermore, in the item storage box described in Patent Document 4, an access opening (removal port) is formed at the top of the side portion (side surface) of the main body (box main body) (adjacent to the edge of the box main body that is perpendicular to the stacking direction of the paper), and unlike Patent Document 3, there is no lid, so when placed on its side, the item (paper) can be easily removed horizontally (see paragraph 0032 and Figure 10 of Patent Document 4), but if you try to remove the item from above at an angle rather than horizontally, the item may get caught on the edge and not be able to be removed properly, or the frictional force may increase.

[0009] The present invention has been made in consideration of the above-mentioned problems, and aims to provide an item storage box that is less likely to allow dust to enter the main body, makes it easy to remove items from above, and reduces frictional forces when removing items. [Means for solving the problem]

[0010] The item storage box according to the present invention is an item storage box in which a plurality of items can be stored in a stacked state, and which is provided with an access port forming portion that serves to form an access port for the items, and which comprises a box-shaped main body consisting of a top surface portion, a bottom surface portion, a front surface portion, a back surface portion, and left and right side surfaces, and the access port forming portion has: a first cut-out portion provided on the ridge line where the top surface portion and the front surface portion intersect, or near the ridge line; a second cut-out portion having one end at the left end of the first cut-out portion and the other end on the inside of the top surface portion; a third cut-out portion having one end at the right end of the first cut-out portion and the other end on the inside of the top surface portion; and a first fold line connecting the other end of the second cut-out portion and the other end of the third cut-out portion, and the access port is formed by cutting the first cut-out portion, the second cut-out portion, and the third cut-out portion, and folding a portion of the top surface portion upward along the first fold line to form a first folded piece.

[0011] In this item storage box, the access opening forming portion has a first cutout portion provided on or near the ridge line where the top surface portion and the front surface portion intersect, a second cutout portion having one end at the left end of the first cutout portion and the other end on the inside of the top surface portion, a third cutout portion having one end at the right end of the first cutout portion and the other end on the inside of the top surface portion, and a first fold line connecting the other end of the second cutout portion and the other end of the third cutout portion, and the access opening is formed by cutting the first cutout portion, the second cutout portion, and the third cutout portion and folding a part of the top surface portion upward along the first fold line to form a first folded piece, and since the first folded piece is positioned above the access opening, dust is less likely to enter the main body.

[0012] Furthermore, when removing an item from above, if the removal angle of the item is less than the bending angle of the first bending piece, the first bending piece does not substantially resist the removal of the item, and even if the removal angle is greater than the bending angle, the first bending piece will deform appropriately in the direction of increasing the bending angle, guiding the removal of the item (acting as a guide for the removal of the item).Therefore, with this item storage box, items can be easily removed from above and frictional forces during removal can also be reduced. [Effects of the Invention]

[0013] According to the present invention, an item storage box is realized that is less susceptible to dust intrusion into the main body, allows items to be easily removed from above, and reduces frictional forces during removal. [Brief explanation of the drawings]

[0015] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same elements are given the same reference numerals and redundant description will be omitted.

[0016] (First embodiment) FIG. 1 shows a first embodiment of an item storage box according to the present invention. The storage box 1 according to this embodiment is configured to store a plurality of items stacked together and includes a main body 10. Examples of the items include tissue paper and other thin paper, paper towels, kitchen paper, gloves, and masks. In this embodiment, the items are tissue paper P, which are stacked as shown in FIG. 2.

[0017] The main body 10 has a rectangular box shape that is long in the left-right direction and includes a top surface 11, a bottom surface 12, a front surface 13, a back surface 14, a left side surface 15, and a right side surface 16. The main body 10 is flexible and may be made of, for example, cardboard or other paper. In this example, the main body 10 is made of paper, and at least the top surface 11 and the front surface 13 are defined by folding the paper.

[0018] The main body 10 is provided with a take-out opening forming portion 17 that serves to form a take-out opening for the tissue paper P. The take-out opening forming portion 17 has, on the upper surface portion 11, a cut line 21, a cut line 22, a cut line 23, a cut line 24, a cut line 25, and a fold line 26.

[0019] The cut line 21 is provided on the upper surface portion 11 near the ridge line 18 where the upper surface portion 11 and the front surface portion 13 intersect. The cut line 21 is a straight line parallel to the ridge line 18. As shown in FIG. 3, if the distance from the ridge line 18 to the cut line 21 is d1, then d1 is preferably 1 to 5 mm, and more preferably 1 to 2 mm.

[0020] Cut line 22 has one end 22a at left end 21a of cut line 21, and the other end 22b on the inside of upper surface portion 11 (i.e., the side closer to the center of upper surface portion 11 and away from ridge line 18). The other end 22b is on a straight line extending from one end 22a in a direction perpendicular to ridge line 18, and cut line 22 is a straight line perpendicular to ridge line 18. If the length of cut line 22 (the distance from one end 22a to the other end 22b) is d2, d2 is preferably 5 to 30 mm, and more preferably 5 to 20 mm.

[0021] Cut line 23 has one end 23a at right end 21b of cut line 21, and the other end 23b located inside top surface portion 11. The other end 23b is on a straight line extending from one end 23a in a direction perpendicular to ridge line 18, and cut line 23 is a straight line perpendicular to ridge line 18 and parallel to cut line 22. The length of cut line 23 (the distance from one end 23a to the other end 23b) is d2, the same as cut line 22, and is preferably 5 to 30 mm, and more preferably 5 to 20 mm.

[0022] Cut line 24 has one end 24a at left end 21a of cut line 21, and the other end 24b at ridge line 18. Cut line 24 is a straight line that is perpendicular to ridge line 18 and continues to cut line 22. Cut line 24 has a length d1 (the distance from one end 24a to the other end 24b), which is preferably 1 to 5 mm, as described above, and more preferably 1 to 2 mm.

[0023] Cut line 25 has one end 25a at right end 21b of cut line 21, and the other end 25b at ridge line 18. Cut line 25 is a straight line that is perpendicular to ridge line 18 and continues to cut line 23. The length of cut line 25 (the distance from one end 25a to the other end 25b) is d1, similar to cut line 24, and is preferably 1 to 5 mm, and more preferably 1 to 2 mm.

[0024] As shown in FIG. 4, incision lines 21, 22, 23, 24, and 25 are formed by perforations consisting of cut portions C and tie portions T. The thickness of the blade that forms cut portions C is usually about 0.25 to 0.4 mm, but here, cut portions C are formed using a blade with a thickness of more than 0.4 mm and not more than 1 mm. As a result, when a user cuts tie portions T to connect adjacent cut portions C and cuts each incision line, as described below, clear irregularities are formed in the cut portions (including not only the portions of tie portions T cut by the user but also the portions of cut portions C previously cut by the blade). Even if a user slides their fingers or the like along the cut incision line, the contact distance with the cut portion is shortened (even if a finger or the like that touches the convex portion toward the user slides, it will move away from the next concave portion and will not come into contact), thereby reducing the risk of the user being cut at the cut portion.

[0025] Fold line 26 is a straight line connecting other end 22b of cut line 22 and other end 23b of cut line 23, and is parallel to ridge line 18 and cut line 21. Fold line 26 may be formed by printing a straight line on top surface portion 11, or may be formed simply by connecting other end 22b and other end 23b without being particularly visible by printing or the like, but it is preferable that it be formed so as to be easy to fold by scoring or the like.

[0026] To remove the tissue paper P from the storage box 1, the user cuts the tie portions T at the cut lines 21, 22, 23, 24 and 25 to connect the adjacent cut portions C, and then cuts the cut lines 21, 22, 23, 24 and 25, thereby making cuts in the removal opening forming portion 17 along the cut lines 21, 22, 23, 24 and 25. The portion of the top surface portion 11 surrounded by the cut lines 21, 24 and 25 stands up due to the restoring force of the folded paper (the force that tries to return to the unfolded state (elastic force generated at the ridge lines 18)), as shown in Figure 5, and this standing portion forms a standing piece 31.

[0027] Next, the user folds the portion of top surface 11 surrounded by cut lines 21, 22, and 23 upward along crease 26, forming bent piece 32 that extends diagonally upward (upward and forward) from crease 26. A gap that leads to the inside of main body 10 is formed between bent piece 32 and standing piece 31, and this gap serves as outlet 33. Unlike outlets on typical tissue paper storage boxes, outlet 33 is not provided with a plastic film, which contributes to reducing plastic waste.

[0028] In the storage box 1 of this embodiment, the access opening forming portion 17 has a cut line 21 provided near the ridge line 18 where the top surface portion 11 and the front surface portion 13 intersect, a cut line 22 having the left end 21a of the cut line 21 as one end 22a and the other end 22b on the inside of the top surface portion 11, a cut line 23 having the right end 21b of the cut line 21 as one end 23a and the other end 23b on the inside of the top surface portion 11, and a fold 26 connecting the other end 22b of the cut line 22 and the other end 23b of the cut line 23, and the cut lines 21, 22 and 23 are cut and a part of the top surface portion 11 is folded upward along the fold 26 to form a folded piece 32, thereby forming the access opening 33, and since the folded piece 32 is positioned above the access opening 33, it is less likely for dust to enter the main body 10.

[0029] In addition, when the tissue paper P is taken out from above, the take-out angle of the tissue paper P (θ P ) is equal to or less than the bending angle of the bending piece 32 (θ in FIG. 5), the bending piece 32 does not substantially resist the removal of the tissue paper P, and even if the removal angle is greater than the bending angle, the bending piece 32 deforms appropriately in the direction of increasing the bending angle, guiding the removal of the tissue paper P (acting as a guide for the removal of the tissue paper P). Therefore, according to the storage box 1, the tissue paper P can be easily removed from above and the frictional force when removing the tissue paper P can also be reduced.

[0030] Furthermore, in the storage box 1, the main body 10 is made of paper, the top surface 11 and the front surface 13 are divided by folding the paper, the cut line 21 is made on the top surface 11 near the ridge line 18, the outlet forming portion 17 has a cut line 24 with one end 24a at the left end 21a of the cut line 21 and the other end 24b at the ridge line 18, and a cut line 25 with one end 25a at the right end 21b of the cut line 21 and the other end 25b at the ridge line 18, the cut lines 24 and 25 are cut together with the cut line 21, and part of the top surface 11 stands up along the ridge line 18 to form the standing piece 31, so that even if the tissue paper P exposed from the outlet 33 tries to droop near the front surface 13, the standing piece 31 supports it from below, making it easier to take out the tissue paper P from above.

[0031] (Second embodiment) 6 shows a second embodiment of an item storage box according to the present invention. Storage box 2 according to this embodiment has the same configuration as storage box 1, except that it has cut lines 41 and 42 instead of cut lines 22 and 23, and has folding pieces 34 (see FIG. 7) instead of folding pieces 32.

[0032] The cut line 41 has one end 41a at the left end 21a of the cut line 21, and the other end 41b located inside the upper surface portion 11 to the left of the one end 41a. The cut line 41 has a wavy (hump-like) shape with repeated recesses 41c recessed to the left and protrusions 41d protruding to the right, and the recesses 41c and protrusions 41d have rounded shapes without corners. If the distance from the one end 41a to the other end 41b in the front-to-rear direction is d3, d3 is preferably 5 to 30 mm, and more preferably 5 to 20 mm.

[0033] The cut line 42 has one end 42a at the right end 21b of the cut line 21, and the other end 42b located on the inside of the upper surface portion 11 to the right of the one end 42a. The cut line 42 is wavy, with repeated rightward recesses 42c and leftward protrusions 42d, and the recesses 42c and protrusions 42d have rounded shapes without corners. The distance in the front-to-rear direction from the one end 42a to the other end 42b is d3, the same as the cut line 41, and is preferably 5 to 30 mm, and more preferably 5 to 20 mm.

[0034] The cut lines 41 and 42 are formed by perforations consisting of cut portions C and tie portions T (see FIG. 4).

[0035] Folding score 26 is a straight line connecting other end 41b of cut line 41 and other end 42b of cut line 42, and is parallel to ridge line 18 and cut line 21 (the distance from cut line 21 to fold score 26 is d3). In storage box 2, fold score 26 may be formed by printing a straight line on top surface 11, or it may be formed simply by connecting other end 41b and other end 42b without being particularly visible by printing or the like; however, if the length of cut line 21 in storage box 2 is the same as that of cut line 21 in storage box 1, the length of fold score 26 in storage box 2 will be longer than that of storage box 1. Therefore, in storage box 2, forming fold score 26 by scoring or the like contributes to the ease of folding more than in storage box 1.

[0036] When the user takes out the paper tissues P from the storage box 2, he or she folds the portion of the top surface 11 surrounded by the cut lines 21, 41, and 42 upward along the crease 26, forming a folded piece 34 that extends diagonally upward (upward and forward) from the crease 26, as shown in Fig. 7. The folded piece 34 has a convex portion 34a that corresponds to the concave portion 41c of the cut line 41 or the concave portion 42c of the cut line 42, and a concave portion 34b that corresponds to the convex portion 41d of the cut line 41 or the convex portion 42d of the cut line 42. A gap that leads to the inside of the main body 10 is formed between the folded piece 34 and the upright piece 31, and this gap serves as the dispensing opening 33. Unlike dispensing openings of typical tissue storage boxes, the dispensing opening 33 is not provided with a plastic film, which contributes to reducing plastic waste.

[0037] In the storage box 2 according to this embodiment, the cut lines 41 and 42 are wavy, so that the convex portion 34a of the folding piece 34 catches on the concave portion 41c of the cut line 41 or the concave portion 42c of the cut line 42, or the concave portion 34b catches on the convex portion 41d of the cut line 41 or the convex portion 42d of the cut line 42, thereby easily maintaining the folding piece 34 at the desired folding angle. This makes it easier to adjust the ease of removal of the tissue paper P, the reduction of frictional force during removal, and the prevention of dust from entering the main body 10.

[0038] Furthermore, the paper tissues P exposed from the outlet 33 are caught in the recessed portion 41c or recessed portion 42c, preventing them from sagging, making it easier to take out the paper tissues P from above. In particular, the other end 41b of the cut line 41 is located to the left of the one end 41a, the other end 42b of the cut line 42 is located to the right of the one end 42a, and the fold line 26 is parallel to the ridge line 18, so that the outlet 33 formed in the top surface 11 narrows towards the front, making it easier for the paper tissues P to get caught in the recessed portion 41c or recessed portion 42c.

[0039] In contrast, the protrusions 41d and 42d have a rounded shape without any corners, so that the tissue paper P is less likely to get caught when taken out, and the user can take out the tissue paper P smoothly.

[0040] (Third embodiment) 8 and 9 show a third embodiment of an item storage box according to the present invention. Storage box 3 according to this embodiment has the same configuration as storage box 1, except that it differs from storage box 1 in that cut lines 51, 52, and 53 are provided instead of cut lines 21, 22, and 23, folding piece 35 (see FIG. 10) is formed instead of folding piece 32, cut lines 24 and 25 are not provided, and cutting lines 61, 62, 63, 64, 65, 66, fold line 67, fold line 68, and fold line 69 are provided.

[0041] In detail, outlet forming portion 17 has, on ridge line 18, a linear cut line 51 that follows ridge line 18. In addition, outlet forming portion 17 has cut line 52, cut line 53, and fold line 26 on top surface portion 11, and has cut line 61, cut line 62, cut line 63, cut line 64, cut line 65, cut line 66, fold line 67, fold line 68, and fold line 69 on front surface portion 13.

[0042] The cut line 52 has one end 52a at the left end 51a of the cut line 51, and the other end 52b located inside the upper surface portion 11 to the left of the one end 52a. The cut line 52 is wavy, with repeated recesses 52c recessed to the left and protrusions 52d protruding to the right, and the recesses 52c and protrusions 52d have rounded shapes without corners. If the distance from the ridge line 18 to the other end 52b (the distance in the front-to-rear direction from the one end 52a to the other end 52b) is d4, then d4 is preferably 6 to 35 mm, and more preferably 6 to 22 mm.

[0043] The cut line 53 has one end 53a at the right end 51b of the cut line 51, and the other end 53b is located on the inside of the upper surface portion 11 to the right of the one end 53a. The cut line 53 is wavy, with recesses 53c recessed to the right and protrusions 53d protruding to the left repeatedly provided, and the recesses 53c and protrusions 53d have rounded shapes without corners. The distance from the ridge line 18 to the other end 53b (the distance in the front-to-rear direction from the one end 53a to the other end 53b) is d4, similar to the cut line 52, and is preferably 6 to 35 mm, and more preferably 6 to 22 mm.

[0044] The cut lines 51, 52 and 53 are formed by perforations consisting of cut portions C and tie portions T (see FIG. 4).

[0045] Folding score 26 is a straight line connecting other end 52b of cut line 52 and other end 53b of cut line 53, and is parallel to ridge line 18 and cut line 51. In storage box 3, folding score 26 may also be formed by printing a straight line on top surface 11, or may simply connect other end 52b and other end 53b without being particularly visible by printing or the like, but if the length of cut line 51 in storage box 3 is the same as cut line 21 in storage box 1, then folding score 26 in storage box 3 will be longer than folding score 26 in storage box 1. Therefore, in storage box 3, forming folding score 26 by scoring or the like contributes to the ease of folding more than in storage box 1.

[0046] The cut line 61 has an upper end 61a at the left end 51a of the cut line 51, and a lower end 61b on the inside of the front portion 13 (that is, on the side closer to the center of the front portion 13 and away from the ridge line 18). The lower end 61b is on a straight line extending from the upper end 61a in a direction perpendicular to the ridge line 18, and the cut line 61 is a straight line perpendicular to the ridge line 18. If the length of the cut line 61 (the distance from the upper end 61a to the lower end 61b) is d5, then d5 is preferably 1 to 7 mm, and more preferably 2 to 5 mm.

[0047] The cut line 62 has an upper end 62a at the right end 51b of the cut line 51, and a lower end 62b on the inside of the front portion 13. The lower end 62b is on a straight line extending from the upper end 62a in a direction perpendicular to the ridge line 18, and the cut line 62 is a straight line perpendicular to the ridge line 18. The length of the cut line 62 (the distance from the upper end 62a to the lower end 62b) is d5, the same as the cut line 61, and is preferably 1 to 7 mm, and more preferably 2 to 5 mm.

[0048] The cut line 63 has an upper end 63a at the lower end 61b of the cut line 61, and the lower end 63b is provided below the cut line 61. The lower end 63b is on a straight line extending from the upper end 63a in a direction perpendicular to the ridge line 18, and the cut line 63 is a straight line continuing from the cut line 61. If the length of the cut line 63 (the distance from the upper end 63a to the lower end 63b) is d6, then d6 is preferably 1 to 7 mm, and more preferably 2 to 5 mm.

[0049] The cut line 64 has an upper end 64a at the lower end 62b of the cut line 62, and a lower end 64b below the cut line 62. The lower end 64b is on a straight line extending from the upper end 64a in a direction perpendicular to the ridge line 18, and the cut line 64 is a straight line continuing from the cut line 62. The length of the cut line 64 (the distance from the upper end 64a to the lower end 64b) is d6, similar to the length of the cut line 63, and is preferably 1 to 7 mm, and more preferably 2 to 5 mm.

[0050] Cut line 65 has upper end 65a at lower end 63b of cut line 63, and lower end 65b is provided below cut line 63. Lower end 65b is on a straight line extending from upper end 65a in a direction perpendicular to ridge line 18, and cut line 65 is a straight line continuing from cut line 63. If the length of cut line 65 (the distance from upper end 65a to lower end 65b) is d7, d7 is preferably 1 to 7 mm, and more preferably 2 to 5 mm.

[0051] The cut line 66 has an upper end 66a which is the lower end 64b of the cut line 64, and the lower end 66b is provided below the cut line 64. The lower end 66b is on a straight line extending from the upper end 66a in a direction perpendicular to the ridge line 18, and the cut line 66 is a straight line continuing from the cut line 64. The length of the cut line 66 (the distance from the upper end 66a to the lower end 66b) is d7, similar to the length of the cut line 65, and is preferably 1 to 7 mm, and more preferably 2 to 5 mm.

[0052] Cut lines 61, 62, 63, 64, 65, and 66 are formed by perforations consisting of cut portions C and tie portions T (see FIG. 4). In addition, the tie portions T are formed longer than the other tie portions T on the cut line 61 side of cut line 63 (the boundary between cut line 61 and cut line 63), the cut line 62 side of cut line 64 (the boundary between cut line 62 and cut line 64), the cut line 63 side of cut line 65 (the boundary between cut line 63 and cut line 65), and the cut line 64 side of cut line 66 (the boundary between cut line 64 and cut line 66).

[0053] The fold line 67 is a straight line connecting the lower end 61b of the cut line 61 and the lower end 62b of the cut line 62, and is parallel to the ridge line 18 and the cut line 51. The fold line 67 may be formed by printing a straight line on the front portion 13, or may be formed simply by connecting the lower end 61b and the lower end 62b without being particularly visible by printing or the like, but it is preferable that the fold line 67 be formed so as to be easy to fold by scoring or the like.

[0054] The fold line 68 is a straight line connecting the lower end 63b of the cut line 63 and the lower end 64b of the cut line 64, and is parallel to the fold line 67. The fold line 68 may be formed by printing a straight line on the front portion 13, or may be formed simply by connecting the lower end 63b and the lower end 64b without being particularly visible by printing or the like, but it is preferable that the fold line 68 be formed so as to be easy to fold by scoring or the like.

[0055] The fold line 69 is a straight line connecting the lower end 65b of the cut line 65 and the lower end 66b of the cut line 66, and is parallel to the fold line 68. The fold line 69 may be formed by printing a straight line on the front portion 13, or may be formed simply by connecting the lower end 65b and the lower end 66b without being particularly visible by printing or the like, but it is preferable that the fold line 69 be formed so as to be easy to fold by scoring or the like.

[0056] To be able to take out tissue paper P from the storage box 3, the user cuts the tie parts T at the cut lines 51, 52 and 53 to connect the adjacent cut parts C, and by cutting the cut lines 51, 52 and 53, makes cuts in the take-out opening forming part 17 along the cut lines 51, 52 and 53.

[0057] Next, the user folds the portion of the top surface portion 11 surrounded by the cut lines 51, 52, and 53 upward along the crease 26, forming a folded piece 35 that extends diagonally upward (upward and forward) from the crease 26. The folded piece 35 has a protrusion 35a corresponding to the recess 52c of the cut line 52 or the recess 53c of the cut line 53, and a recess 35b corresponding to the protrusion 52d of the cut line 52 or the protrusion 53d of the cut line 53 (see FIG. 10 ). A gap that leads to the inside of the main body 10 is formed between the folded piece 35 and the ridge line 18 (the upper edge of the front surface portion 13), and this gap serves as the dispensing opening 33. Unlike the dispensing openings of typical tissue storage boxes, the dispensing opening 33 is not provided with a plastic film, which contributes to reducing plastic waste.

[0058] In the storage box 3, the outlet 33 can be enlarged to make it easier to take out the tissue paper P.

[0059] At this time, the user forms the folding piece 35, cuts the tie portions T at the cut lines 61 and 62 to connect the adjacent cut portions C, and cuts the cut lines 61 and 62, thereby making a cut in the outlet forming portion 17 along the cut lines 61 and 62. Then, as shown in FIG. 10 , the user folds the portion of the front portion 13 surrounded by the cut lines 61 and 62 forward along the fold line 67, and forms the folding piece 36 that extends diagonally forward (forward and upward) from the fold line 67 using this portion. The gap formed between the folding piece 36 and the folding piece 35 becomes the enlarged outlet 33.

[0060] When the remaining amount of tissue paper P in the storage box 3 decreases and the stack height decreases, the user can cut the tie portions T at the cut lines 63 and 64 to connect the adjacent cut portions C, and by cutting the cut lines 63 and 64, make cuts in the outlet forming portion 17 along the cut lines 63 and 64, and then fold the portion of the front portion 13 surrounded by the cut lines 63 and 64 forward along the fold lines 68. This expands the folding piece 36 downward and enlarges the outlet 33, making it easier to take out the tissue paper P.

[0061] When the remaining amount of tissue paper P becomes even smaller, the user cuts the tie portions T at the cut lines 65 and 66 to connect the adjacent cut portions C, and by cutting along the cut lines 65 and 66, makes a slit in the outlet forming portion 17 along the cut lines 65 and 66, and can then fold the portion of the front portion 13 surrounded by the cut lines 65 and 66 forward along the fold line 69. As a result, as shown in Figure 11, the folding piece 36 extends further downward and the outlet 33 becomes larger, making it easier to take out the remaining tissue paper P.

[0062] In the storage box 3 of this embodiment, the access opening forming portion 17 has a cut line 51 provided on the ridge 18 where the top surface portion 11 and the front surface portion 13 intersect, a cut line 52 having the left end 51a of the cut line 51 as one end 52a and the other end 52b on the inside of the top surface portion 11, a cut line 53 having the right end 51b of the cut line 51 as one end 53a and the other end 53b on the inside of the top surface portion 11, and a fold 26 connecting the other end 52b of the cut line 52 and the other end 53b of the cut line 53, and the cut lines 51, 52 and 53 are cut and a part of the top surface portion 11 is folded upward along the fold 26 to form a folding piece 35, thereby forming the access opening 33, and since the folding piece 35 is positioned above the access opening 33, it is less likely for dust to enter the main body 10.

[0063] Furthermore, when tissue paper P is taken out from above, if the take-out angle of tissue paper P is equal to or less than the bending angle of bending piece 35, bending piece 35 does not substantially resist taking out tissue paper P, and even if the take-out angle is greater than the bending angle, bending piece 35 deforms appropriately in the direction of increasing the bending angle, guiding the taking-out of tissue paper P. Therefore, according to storage box 3, tissue paper P can be easily taken out from above and frictional force during taking-out can also be suppressed.

[0064] In the storage box 3, the cut lines 52 and 53 are wavy, so that the convex portion 35a of the folding piece 35 catches on the concave portion 52c of the cut line 52 or the concave portion 53c of the cut line 53, or the concave portion 35b catches on the convex portion 52d of the cut line 52 or the convex portion 53d of the cut line 53, thereby easily maintaining the folding piece 35 at the desired folding angle. This makes it easier to adjust the ease of taking out the tissue paper P, suppressing frictional force when taking out the tissue paper P, and preventing dust from entering the main body 10.

[0065] Furthermore, the paper tissues P exposed from the outlet 33 are caught in the recessed portion 52c or the recessed portion 53c, preventing them from sagging, making it easier to take out the paper tissues P from above. In particular, the other end 52b of the cut line 52 is located to the left of the one end 52a, the other end 53b of the cut line 53 is located to the right of the one end 53a, and the fold line 26 is parallel to the ridge line 18, so that the outlet 33 formed in the top surface 11 narrows towards the front, making it easier for the paper tissues P to get caught in the recessed portion 52c or the recessed portion 53c.

[0066] In contrast, the protrusions 52d and 53d have a rounded shape without any corners, so that the tissue paper P is less likely to get caught when taken out, and the user can take out the tissue paper P smoothly.

[0067] In the storage box 3, the removal opening forming portion 17 has a cut line 61 having an upper end 61a at the left end 51a of the cut line 51 and a lower end 61b on the inside of the front surface portion 13, a cut line 62 having an upper end 62a at the right end 51b of the cut line 51 and a lower end 62b on the inside of the front surface portion 13, and a fold line 67 connecting the lower end 61b of the cut line 61 and the lower end 62b of the cut line 62, and the cut lines 61 and 62 are cut along with the cut line 51, and part of the front surface portion 13 is folded forward along the fold line 67 to form the folded piece 36, making it easy to remove the tissue paper P, especially when the height of the stack of tissue paper P is low and slightly away from the top surface portion 11.

[0068] Furthermore, the removal opening forming portion 17 has a cut line 63 having an upper end 63a at the lower end 61b of the cut line 61 and having a lower end 63b below the cut line 61, a cut line 64 having an upper end 64a at the lower end 62b of the cut line 62 and having a lower end 64b below the cut line 62, and a fold line 68 connecting the lower end 63b of the cut line 63 and the lower end 64b of the cut line 64, and by cutting the cut lines 63 and 64 and folding part of the front portion 13 forward along the fold line 68, the folded piece 36 is expanded, making it easier to remove the tissue paper P when the remaining amount of tissue paper P is low.

[0069] Even when the remaining amount of tissue paper P becomes even less, the outlet forming portion 17 has a cut line 65 having an upper end 65a at the lower end 63b of the cut line 63 and a lower end 65b below the cut line 63, a cut line 66 having an upper end 66a at the lower end 64b of the cut line 64 and a lower end 66b below the cut line 64, and a fold line 69 connecting the lower end 65b of the cut line 65 and the lower end 66b of the cut line 66, and by cutting the cut lines 65 and 66 and folding part of the front portion 13 forward along the fold line 69, the folded piece 36 is expanded, making it easier to take out even the little remaining tissue paper P.

[0070] Here, the lower end 61b of the cut line 61 is provided on a straight line extending from the upper end 61a of the cut line 61 in a direction perpendicular to the ridge line 18, the lower end 62b of the cut line 62 is provided on a straight line extending from the upper end 62a of the cut line 62 in a direction perpendicular to the ridge line 18, the lower end 63b of the cut line 63 is provided on a straight line extending from the upper end 63a of the cut line 63 in a direction perpendicular to the ridge line 18, and the lower end 64b of the cut line 64 is provided on a straight line extending from the upper end 64a of the cut line 64 in a direction perpendicular to the ridge line 18. The lower end 65b of line 65 is located on a straight line extending from the upper end 65a of cut line 65 in a direction perpendicular to ridge line 18, and the lower end 66b of cut line 66 is located on a straight line extending from the upper end 66a of cut line 66 in a direction perpendicular to ridge line 18, and fold lines 67, 68 and 69 are parallel to ridge line 18, so that the downward expansion of folding piece 36 and the downward expansion of take-out opening 33 are carried out with equal width in the left-right direction, maintaining ease of removal of tissue paper P regardless of the remaining amount of tissue paper P.

[0071] Furthermore, cut lines 61, 62, 63, 64, 65 and 66 are formed by perforations consisting of cut portions C and tie portions T, and the tie portions T on the cut line 61 side of cut line 63 and the cut line 62 side of cut line 64, and on the cut line 63 side of cut line 65 and the cut line 64 side of cut line 66 are formed longer than the other tie portions T. Therefore, when first cutting the perforations of cut lines 61 and 62 to cut through cut lines 61 and 62, the cut is prevented from inadvertently progressing to cut lines 63 and 64, and next cutting the perforations of cut lines 63 and 64 to cut through cut lines 63 and 64, the cut is prevented from inadvertently progressing to cut lines 65 and 66.

[0072] (Fourth embodiment) 12 and 13 show a fourth embodiment of an item storage box according to the present invention. Storage box 4 according to this embodiment has a cut line 71 extending from bottom 12 to back 14, a crease 72 on back 14, and a cut line 81 and a crease 82 on front 13. It differs from storage box 1 in that main body 10 can be transformed into a raised bottom state, but has the same configuration as storage box 1.

[0073] Cut line 71 is formed along a single continuous line from bottom portion 12 to back portion 14. Cut line 71 includes bottom cut portion 73, bottom cut portion 74, bottom cut portion 75, back cut portion 76, and back cut portion 77. Bottom cut portion 73, bottom cut portion 74, and bottom cut portion 75 are formed on bottom portion 12. Back cut portion 76 and back cut portion 77 are formed on back portion 14. Bottom cut portion 73, bottom cut portion 74, bottom cut portion 75, back cut portion 76, and back cut portion 77 are all linear.

[0074] Bottom cutout portion 73 and bottom cutout portion 74 extend from ridge line 19 where bottom portion 12 and back portion 14 intersect toward front portion 13. Bottom cutout portion 73 and bottom cutout portion 74 are perpendicular to ridge line 19. Bottom cutout portion 75 connects bottom cutout portion 73 and bottom cutout portion 74. Specifically, bottom cutout portion 75 connects one end 73a of bottom cutout portion 73 to one end 74a of bottom cutout portion 74. One end 73a of bottom cutout portion 73 and one end 74a of bottom cutout portion 74 are located in the middle of bottom portion 12. Here, the middle of bottom portion 12 refers to the part of bottom portion 12 other than the edges (boundaries with front portion 13, back portion 14, left side portion 15, and right side portion 16). The bottom cutout portion 75 extends parallel to the ridge line 19 .

[0075] The rear cutout portion 76 and the rear cutout portion 77 are continuous with the bottom cutout portion 73 and the bottom cutout portion 74, respectively. That is, the lower end 76b of the rear cutout portion 76 and the lower end 77b of the rear cutout portion 77 are connected to the other end 73b of the bottom cutout portion 73 and the other end 74b of the bottom cutout portion 74, respectively. The rear cutout portion 76 and the rear cutout portion 77 extend in the height direction (vertical direction) of the main body 10. The upper end 76a of the rear cutout portion 76 and the upper end 77a of the rear cutout portion 77 are located in the middle of the rear portion 14. Here, the middle portion of the rear portion 14 refers to the part of the rear portion 14 other than the edges (boundaries with the top surface portion 11, the bottom surface portion 12, the left side surface portion 15, and the right side surface portion 16).

[0076] The cut lines 71 (bottom cut portions 73, 74, 75, back cut portions 76 and 77) are formed by perforations consisting of cut portions C and tie portions T (see FIG. 4).

[0077] The fold line 72 is a straight line connecting the upper end 76a of the back cut-out portion 76 and the upper end 77a of the back cut-out portion 77, and is parallel to the ridge line 19. The fold line 72 may be formed by printing a straight line on the back portion 14, or may be formed by simply connecting the upper end 76a and the upper end 77a without being particularly visible by printing or the like, but it is preferable that the fold line 72 be formed so as to be easy to fold by scoring or the like.

[0078] In the bottom surface portion 12 and the back surface portion 14, the portion surrounded by the bottom surface cutout portion 73, the bottom surface cutout portion 74, the bottom surface cutout portion 75, the back surface cutout portion 76, the back surface cutout portion 77 and the fold line 72 is a tongue portion 91 that becomes a tongue portion 101 connected to the middle portion of the back surface portion 14 when a cut is made in the main body 10 along the cut line 71. The tongue portion 101 is formed from a single plate consisting of a part of the bottom surface portion 12 and a part of the back surface portion 14. In this embodiment, the tongue portion 101 is rectangular. The fold line 72 is for bending the tongue portion 101 toward the front surface portion 13 and is provided at a height position similar to that of a slit portion 92, which will be described later.

[0079] The cut line 81 is formed on the front portion 13. The cut line 81 includes a horizontal cut portion 83, a vertical cut portion 84, a vertical cut portion 85, a vertical cut portion 86, and a vertical cut portion 87. The horizontal cut portion 83, the vertical cut portion 84, the vertical cut portion 85, the vertical cut portion 86, and the vertical cut portion 87 are all linear.

[0080] The horizontal cutout 83 is located in the middle of the front surface 13, extends in the left-right direction of the main body 10, and is parallel to the ridge line 18. Here, the middle of the front surface 13 refers to the part of the front surface 13 other than the edges (boundaries with the top surface 11, bottom surface 12, left side surface 15, and right side surface 16).

[0081] The vertical cut portion 84, the vertical cut portion 85, the vertical cut portion 86, and the vertical cut portion 87 extend upward from the horizontal cut portion 83. The vertical cut portion 84, the vertical cut portion 85, the vertical cut portion 86, and the vertical cut portion 87 are provided in this order from the left end 83a of the horizontal cut portion 83 toward the right end 83b.

[0082] Specifically, vertical cutout portion 84 has its lower end 84b at left end 83a of horizontal cutout portion 83 and its upper end 84a above left end 83a, and extends in the height direction of main body 10. If the length of vertical cutout portion 84 (the distance from upper end 84a to lower end 84b) is d8, d8 is preferably 1 to 15 mm, and more preferably 2 to 10 mm.

[0083] Vertical cutout portion 87 has its lower end 87b located at right end 83b of horizontal cutout portion 83 and its upper end 87a located above right end 83b, and extends in the height direction of main body 10. The length of vertical cutout portion 87 (the distance from upper end 87a to lower end 87b) is d8, the same as vertical cutout portion 84, and is preferably 1 to 15 mm, and more preferably 2 to 10 mm.

[0084] The vertical cut portion 85 has a lower end 85b at the middle portion 83c of the horizontal cut portion 83 and an upper end 85a above and to the left of the middle portion 83c, and extends at an angle relative to the height direction of the main body 10.

[0085] The vertical cutout portion 86 has its lower end 86b located in an intermediate portion 83d between the intermediate portion 83c and the right end 83b of the horizontal cutout portion 83, and its upper end 86a located above and to the right of the intermediate portion 83d, and extends at an angle relative to the height direction of the main body 10. The vertical cutout portion 86 is symmetrical to the vertical cutout portion 85 with respect to a vertical line passing through the center of the front portion 13 in the left-right direction as the axis of symmetry.

[0086] The cut lines 81 (horizontal cut portions 83, vertical cut portions 84, 85, 86 and 87) are formed by perforations consisting of cut portions C and tie portions T (see FIG. 4).

[0087] The fold line 82 is a straight line connecting the upper end 84a of the vertical slit portion 84 and the upper end 87a of the vertical slit portion 87, and is parallel to the ridge line 18. The fold line 82 includes a left portion 82a connecting the upper end 84a of the vertical slit portion 84 and the upper end 85a of the vertical slit portion 85, a central portion 82b connecting the upper end 85a of the vertical slit portion 85 and the upper end 86a of the vertical slit portion 86, and a right portion 82c connecting the upper end 86a of the vertical slit portion 86 and the upper end 87a of the vertical slit portion 87. The fold line 82 may be formed by printing a straight line on the front portion 13, or may be formed without being particularly visible by printing or the like, simply connecting the upper ends 84a and 87a, however, it is preferable that the fold line be formed to make it easier to fold by scoring or the like.

[0088] The left part 82a of the folding line 82 is for folding the part surrounded by the horizontal cut portion 83, the vertical cut portion 84, and the vertical cut portion 85, and this part is folded forward (outside the main body 10) to form a folded piece 93, the central part 82b of the folding line 82 is for folding the part surrounded by the horizontal cut portion 83, the vertical cut portion 85, and the vertical cut portion 86, and this part is folded backward (inside the main body 10) to form a folded piece 94, and the right part 82c of the folding line 82 is for folding the part surrounded by the horizontal cut portion 83, the vertical cut portion 86, and the vertical cut portion 87, and this part is folded forward to form a folded piece 95 (see Figure 14).

[0089] In the front portion 13, the portion surrounded by the horizontal cut portion 83, the vertical cut portion 84, the vertical cut portion 87, and the fold line 82 is a slit portion 92 that is located in the middle of the front portion 13 and serves as a slit 102 into which a tongue piece 101 can be inserted. The slit 102 is a horizontally long opening that extends parallel to the ridge line 18, and includes folding pieces 93, 94, and 95. The tongue piece 101 is configured to be parallel to the bottom portion 12 when inserted into the slit 102 while contacting the lower edges of the folding pieces 93, 94, and 95.

[0090] Next, an example of a method for deforming the main body 10 will be described. First, a cut is made in the main body 10 along the cut line 81. Then, the portion surrounded by the horizontal cut portion 83, the vertical cut portion 84, and the vertical cut portion 85 is folded forward along the left portion 82a of the fold line 82 to form a folded piece 93, the portion surrounded by the horizontal cut portion 83, the vertical cut portion 85, and the vertical cut portion 86 is folded backward along the center portion 82b of the fold line 82 to form a folded piece 94, and the portion surrounded by the horizontal cut portion 83, the vertical cut portion 86, and the vertical cut portion 87 is folded forward along the right portion 82c of the fold line 82 to form a folded piece 95, thereby turning the slit portion 92 into a slit 102.

[0091] Next, by making cuts in the main body 10 along the cut lines 71, the tongue portion 91 is made into a tongue 101. This tongue 101 is folded along the crease 72 toward the front portion 13 and inserted into the slit 102 as shown in Figures 14 and 15, whereby the main body 10 can be deformed so that the tongue 101 is inserted into the slit 102.

[0092] After the deformation, the paper tissues P are placed on the tongue 101 of the main body 10. By raising the bottom surface 12 of the main body 10 and bringing the paper tissues P closer to the top surface 11 in this way, the paper tissues P can be smoothly taken out from the outlet 33 even when the remaining amount of paper tissues P is low. In this case, the distance from the tongue 101 to the top surface 11 is preferably 3 cm or more and 6 cm or less. Note that the paper tissues P are not shown in Figures 14 and 15.

[0093] In the storage box 4 according to this embodiment, the main body 10 has a cut line 71 formed from the bottom surface 12 to the back surface 14, a cut line 81 formed on the front surface 13, a tongue portion 91 that becomes the tongue portion 101 connected to the middle portion of the back surface 14 when the cut line 71 is cut, and a slit portion 92 that becomes the slit 102 located in the middle portion of the front surface 13 and into which the tongue portion 101 can be inserted when the cut line 81 is cut, and by inserting the tongue portion 101 into the slit 102, the tongue portion 101 can be hung from the middle portion of the back surface 14 to the middle portion of the front surface 13. Therefore, when the remaining amount of tissue paper P is low, by inserting the tongue portion 101 into the slit 102 so that the tissue paper P is placed on the tongue portion 101, the bottom of the storage box 4 can be raised while the tongue portion 101 comes into surface contact with the tissue paper P. Therefore, it is possible to stably support the paper tissues P when the bottom is raised without providing a separate member for raising the bottom from the main body 10.

[0094] Further, the cut line 81 has a cut line 83 extending in the left-right direction, and cut lines 84, 85, 86, and 87 extending upward from the cut line 83 in this order, and the storage box 4 (main body 10) has a left part 82a of a fold line 82 connecting an upper end 84a of the cut line 84 and an upper end 85a of the cut line 85, a central part 82b of the fold line 82 connecting an upper end 85a of the cut line 85 and an upper end 86a of the cut line 86, and a right part 82c of the fold line 82 connecting an upper end 86a of the cut line 86 and an upper end 87a of the cut line 87, and the cut lines 83, 84, 85, and 87 extend upward from the cut line 83. 16 , the height of the insertion space 103 for the tongue 101 in the slit 102 can be made higher than when there are no folding pieces, and the tongue 101 can be easily inserted. After the insertion of the tongue 101 is completed, a downward force is applied to at least one of the folding pieces 93, 94, and 95 so that the folding piece 101 comes into stronger contact with the tongue 101, thereby making it difficult for the tongue 101 to come out of the slit 102. Here, the bending directions of folding pieces 93, 94, and 95 are different in the front and rear, making tongue piece 101 less likely to come out of slit 102. In addition, when tongue piece 101 tries to tilt in a side view due to some external force (when the height changes between the front and rear), the tilt can be prevented at multiple points in the front and rear (the lower edges of folding pieces 93 and 95 in the front, and the lower edge of folding piece 94 in the rear).

[0095] (Fifth embodiment) 17 shows a fifth embodiment of an item storage box according to the present invention. Storage box 5 according to this embodiment has the same configuration as storage box 1, except that it differs from storage box 1 in that it has cut lines 51, 52, and 53 instead of cut lines 21, 22, and 23, has crease 27 instead of crease 26, has crease 37 (see FIG. 19) instead of crease 32, and does not have slit lines 24 and 25.

[0096] In detail, the outlet forming portion 17 has a linear cut line 51 on the ridge line 18 that follows the ridge line 18. The outlet forming portion 17 also has cut lines 52, 53 and fold lines 27 on the top surface portion 11.

[0097] Cut line 52 has one end 52a at left end 51a of cut line 51, and the other end 52b located inside top surface portion 11. The other end 52b is on a straight line extending from one end 52a in a direction perpendicular to ridge line 18, and cut line 52 is linearly perpendicular to ridge line 18. If the length of cut line 52 (the distance from one end 52a to the other end 52b) is d9, d9 is preferably 5 to 30 mm, and more preferably 5 to 20 mm.

[0098] Cut line 53 has one end 53a at right end 51b of cut line 51, and the other end 53b is provided inside top surface portion 11. The other end 53b is on a straight line extending from one end 53a in a direction perpendicular to ridge line 18, and cut line 53 is a straight line perpendicular to ridge line 18 and parallel to cut line 52. The length of cut line 53 (the distance from one end 53a to the other end 53b) is d9, the same as cut line 52, and is preferably 5 to 30 mm, and more preferably 5 to 20 mm.

[0099] The cut lines 51, 52 and 53 are formed by perforations consisting of cut portions C and tie portions T (see FIG. 4).

[0100] The crease 27 is a slit connecting the other end 52b of the slit line 52 and the other end 53b of the slit line 53. line51) and preferably forms a circular or elliptical arc. The curvature of crease 27 is preferably 1.9% or more to strengthen the return force acting on bent piece 37. However, since an excessively strong return force may make it difficult to remove an article from the removal opening, the curvature is preferably 9.7% or less, and more preferably 4.8% or less (see International Publication No. 2024 / 117271). Here, the curvature is a numerical value reflecting the magnitude of the curve. As shown in FIG. 18, when the smallest rectangle R that can contain the curve (FIG. 18 illustrates crease 27) is assumed, the distance between both ends of the curve, which corresponds to the length of one side (the long side in FIG. 18), is r1, and the distance from the other side (the short side in FIG. 18) of rectangle R to the apex of the curve, which corresponds to the length of that side, is r2. The curvature is the value obtained by dividing r2 by r1. Here, for example, r1 is 120 mm or more and 200 mm or less, and r2 is 2 mm or more and 20 mm or less. Folding line 27 may be formed by printing a straight line on top surface portion 11, or may be formed simply by connecting other end 52b and other end 53b without being particularly visible by printing or the like, but it is desirable to form it so that it is easy to fold by scoring or the like.

[0101] To be able to take out tissue paper P from the storage box 5, the user cuts the tie parts T at the cut lines 51, 52 and 53 to connect the adjacent cut parts C, and by cutting the cut lines 51, 52 and 53, makes cuts in the take-out opening forming part 17 along the cut lines 51, 52 and 53.

[0102] Next, the user folds the portion of top surface 11 surrounded by cut lines 51, 52, and 53 upward along crease 27, forming bent piece 37 that extends diagonally upward (upward and forward) from crease 27, as shown in Figure 19. A gap that leads to the inside of main body 10 is formed between bent piece 37 and ridge line 18 (upper edge of front surface 13), and this gap serves as outlet 33. Unlike outlets on typical tissue storage boxes, outlet 33 is not provided with a plastic film, which contributes to reducing plastic waste.

[0103] In the storage box 5 according to this embodiment, the fold line 27 is curved and bulges out on the opposite side of the cut line 51, so that the bent piece 37 bent along the fold line 27 is more likely to be subjected to a restoring force (a curve force based on the curvature rate of the curve) that causes it to return to its pre-bending state, thereby preventing the removal opening 33 from widening and making it easier for dust to enter the main body 10.

[0104] Furthermore, cut line 51 is provided on ridge line 18, the other end 52b of cut line 52 is provided on a straight line extending from one end 52a in a direction perpendicular to ridge line 18, and the other end 53b of cut line 53 is provided on a straight line extending from one end 53a in a direction perpendicular to ridge line 18. This shortens the length of the cut line that the user must cut to form folding piece 37 (and thus dispensing opening 33), and the cut itself can be made straight and easy, simplifying the task of taking out tissue paper P.

[0105] The present invention is not limited to the above embodiment, and various modifications are possible. In the above embodiment, tissue paper, which is thin paper, is used as an example of an item to be stored in the storage box, but the present invention is not limited to this.

[0106] Furthermore, it goes without saying that the fold line 26 in the first to fourth embodiments may be curved like the fold line 27 in the fifth embodiment instead of being straight, and the cut line 61, the cut line 62, the cut line 63, the cut line 64, the cut line 65, the cut line 66, the fold line 67, the fold line 68 and the fold line 69 in the third embodiment, and the cut line 71, the fold line 72, the cut line 81 and the fold line 82 in the fourth embodiment may be provided in the fifth embodiment.

[0107] Each cut line can be made by any method other than perforations, and the shape (straight, wavy, etc.) and arrangement of the cut lines can also be arbitrary. For example, as shown in Fig. 20 for a storage box 6, the fold line 26 of the first embodiment is replaced with the fold line 27 of the third embodiment, and the cut line 21 is made into a wavy perforation, and the shortest distance d from the ridge line 18 to the cut line 21 is 101~5mm, maximum distance d 11 is 1 to 10 mm, the length (wavelength) of the waveform is 5 to 10 mm, the length d2 of the cut lines 22 and 23 is 5 to 30 mm, and the distance d 12 The distance between the cut line and the cut portion can be set to 1 to 5 mm. By making the cut line wavy in this way, even if the user slides their fingers along the cut line, the contact distance with the cut portion is shortened (even if the fingers slide after touching the peaks of the waveform toward the user, they will move away from the next valley and will not come into contact), thereby reducing the risk of the user being cut at the cut portion.

[0108] Furthermore, the tongue portion in the fourth embodiment may be formed from the bottom portion to the front portion rather than from the bottom portion to the back portion, the slit portion may be formed in the back portion rather than the front portion, the number of folded pieces of the slit in the fourth embodiment may be four or more or two or less (including zero) rather than three, and the direction of folding forward and backward may also be changed as appropriate.
