Description

Technical Field

[0001] The present invention relates to an article storage box for storing a plurality of articles in a stacked state. Background Art

[0002] As a conventional article storage box, for example, there is a tissue box described in Patent Document 1. The article storage box described in Patent Document 1 includes a box-shaped main body (tissue box main body) and stores a plurality of articles (tissues) in a stacked state. On the upper surface portion (upper surface plate) of the main body, an outlet forming portion (tissue outlet portion) for forming an outlet for the articles is provided at the center thereof. In the outlet forming portion, a wavy dotted line is formed along the center line that bisects the upper surface portion in the short side direction.

[0003] In this article storage box, after forming a slit along the dotted line, the portions (bending pieces) on both sides of the slit are bent obliquely upward, so as to form a gap serving as the outlet between the bending pieces. However, if the bending angle of the bending pieces is small and the gap between the bending pieces is too narrow, the frictional force between the bending pieces and the articles becomes large (as a result, the amount of paper dust generated from the tissues increases). If the bending angle of the bending pieces is large and the gap between the bending pieces is too wide, there is a problem that dust easily enters the main body through the outlet.

[0004] On the other hand, as an article storage box having an outlet formed on a side surface portion or a front surface portion instead of the upper surface portion of the main body, for example, there are a storage box for kitchen paper described in Patent Document 2, a storage box for toilet paper described in Patent Document 3, and a storage box for paper described in Patent Document 4.

[0011] Problems to be Solved by the Invention

[0012] In the article storage boxes described in Patent Documents 2 to 4, compared with the case where the take-out opening is formed in the upper surface portion, it is easier to prevent dust from entering the main body. However, as in the article storage box described in Patent Document 2, if the take-out opening (take-out opening portion) is formed at the center in the vertical direction of the side surface portion (side surface) of the main body (box portion), when stacking the stored articles (kitchen paper folded and overlapped in a pop-up form) to the upper part inside the main body, it will hinder the taking out of the articles located above.

[0013] On the other hand, in the article storage box described in Patent Document 3, a contour cutting line is provided at the upper part (directly below the fold line between the front panel and the upper surface panel) of the front surface portion (front panel) of the main body (box body). The take-out opening (take-out port) is formed by cutting along the contour cutting line. However, at this time, there is a problem that the cover along the contour shape of the contour cutting line covers the part of the article (toilet paper folded alternately in a pop-up take-out manner) pulled out from the take-out opening from above. If the article is not pulled out toward the lower front side of the article storage box, it is difficult to take out.

[0014] In addition, in the article storage box described in Patent Document 4, a take-out opening (take-out port) is formed at the upper part (adjacent to the edge perpendicular to the multi-layer direction of the paper of the box body) of the side surface portion (side surface) of the main body (box main body). Different from Patent Document 3, there is no cover. Therefore, when placed horizontally, the article (paper) can be taken out well in the horizontal direction (refer to paragraph 0032 of Patent Document 4, Figure 10 )). However, if the article is to be taken out from an obliquely upper direction instead of the horizontal direction, the article may get stuck on the edge and cannot be taken out smoothly, or the frictional force may become larger.

[0015] The present invention has been completed in view of the above problems, and its purpose is to provide an article storage box in which dust is difficult to enter the main body, articles can be easily taken out from above, and the frictional force during taking out can also be suppressed.

[0016] Means for Solving the Problem

[0017] The article storage box of the present invention stores a plurality of articles in a stacked state and is provided with an outlet forming portion for forming an outlet for the articles. It is characterized in that the article storage box includes a box-shaped main body including an upper surface portion, a bottom surface portion, a front surface portion, a back surface portion, and left and right side surface portions. The outlet forming portion has: a first cut portion provided at or near the ridge line where the upper surface portion and the front surface portion intersect; a second cut portion having one end at the left end of the first cut portion and the other end provided inside the upper surface portion; a third cut portion having one end at the right end of the first cut portion and the other end provided inside the upper surface portion; and a first crease connecting the other ends of the second cut portion and the third cut portion. By cutting the first cut portion, the second cut portion, and the third cut portion and bending a part of the upper surface portion upward along the first crease to form a first bent piece, the outlet is formed.

[0018] In this article storage box, the outlet forming portion has: a first cut portion provided at or near the ridge line where the upper surface portion and the front surface portion intersect; a second cut portion having one end at the left end of the first cut portion and the other end provided inside the upper surface portion; a third cut portion having one end at the right end of the first cut portion and the other end provided inside the upper surface portion; and a first crease connecting the other ends of the second cut portion and the third cut portion. By cutting the first cut portion, the second cut portion, and the third cut portion and bending a part of the upper surface portion upward along the first crease to form a first bent piece, the outlet is formed. Therefore, the first bent piece is located above the outlet, and dust is difficult to enter the main body.

[0019] In addition, when taking out an article from above, if the taking-out angle of the article is less than or equal to the bending angle of the first bent piece, the first bent piece will not substantially hinder the taking-out of the article. Even if the taking-out angle is greater than the bending angle, the first bent piece will deform appropriately in the direction of increasing the bending angle while guiding the taking-out of the article (serving as a guide for the taking-out of the article). Therefore, according to this article storage box, it is easy to take out the article from above, and the friction during taking-out can also be suppressed.

[0020] Effects of the Invention

[0021] According to the present invention, it is possible to realize an article storage box in which dust is difficult to enter the main body, it is easy to take out the article from above, and the friction during taking-out can also be suppressed. Description of the Drawings

[0042] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same reference numerals are assigned to the same elements, and redundant descriptions are omitted.

[0043] (First Embodiment)

[0044] Figure 1 This shows the first embodiment of the article storage box of the present invention. The storage box 1 of this embodiment stores a plurality of articles in a stacked state and includes a main body 10. As the articles, for example, thin papers such as tissue paper, paper towels, kitchen paper, gloves, and masks can be cited. In this embodiment, the article is a tissue paper P, and it is stacked as Figure 2 shown.

[0045] The main body 10 has a box shape of a long rectangular parallelepiped in the left-right direction, and includes an upper surface portion 11, a bottom surface portion 12, a front surface portion 13, a back surface portion 14, a left side surface portion 15, and a right side surface portion 16. The main body 10 has flexibility, and as its material, for example, paper such as thick paper can be used. Here, the main body 10 is made of paper, and at least the upper surface portion 11 and the front surface portion 13 are divided by bending the paper.

[0046] A take-out opening forming portion 17 for forming a take-out opening of the tissue paper P is provided in the main body 10. The take-out opening forming portion 17 has cut-in lines 21, 22, 23, 24, 25, and a crease 26 on the upper surface portion 11.

[0047] The cut-in line 21 is provided near the ridge line 18 where the upper surface portion 11 and the front surface portion 13 intersect in the upper surface portion 11. The cut-in line 21 has a straight line shape parallel to the ridge line 18. As Figure 3 shown, if the distance from the ridge line 18 to the cut-in line 21 is set to d1, then d1 is preferably 1 to 5 mm, more preferably 1 to 2 mm.

[0048] The cut-in line 22 has one end 22a at the left end 21a of the cut-in line 21, and the other end 22b is provided inside the upper surface portion 11 (that is, on the side away from the ridge line 18 and closer to the central portion of the upper surface portion 11). The other end 22b is located on a straight line extending in a direction orthogonal to the ridge line 18 from the one end 22a, and the cut-in line 22 is in a straight line shape orthogonal to the ridge line 18. If the length of the cut-in line 22 (the distance from the one end 22a to the other end 22b) is set as d2, then d2 is preferably 5 to 30 mm, and more preferably 5 to 20 mm.

[0049] The cut-in line 23 has one end 23a at the right end 21b of the cut-in line 21, and the other end 23b is provided inside the upper surface portion 11. The other end 23b is located on a straight line extending in a direction orthogonal to the ridge line 18 from the one end 23a, and the cut-in line 23 is in a straight line shape orthogonal to the ridge line 18 and parallel to the cut-in line 22. The length of the cut-in line 23 (the distance from the one end 23a to the other end 23b) is the same as that of the cut-in line 22, which is d2, preferably 5 to 30 mm, and more preferably 5 to 20 mm.

[0050] The cut-in line 24 has one end 24a at the left end 21a of the cut-in line 21, and the other end 24b is provided on the ridge line 18. The cut-in line 24 is in a straight line shape orthogonal to the ridge line 18 and continuous with the cut-in line 22. The length of the cut-in line 24 (the distance from the one end 24a to the other end 24b) is d1, as described above, preferably 1 to 5 mm, and more preferably 1 to 2 mm.

[0051] The cut-in line 25 has one end 25a at the right end 21b of the cut-in line 21, and the other end 25b is provided on the ridge line 18. The cut-in line 25 is in a straight line shape orthogonal to the ridge line 18 and continuous with the cut-in line 23. The length of the cut-in line 25 (the distance from the one end 25a to the other end 25b) is the same as that of the cut-in line 24, which is d1, preferably 1 to 5 mm, and more preferably 1 to 2 mm.

[0052] As Figure 4 shown, the cut-in line 21, the cut-in line 22, the cut-in line 23, the cut-in line 24, and the cut-in line 25 are formed by dotted lines including a cutting portion C and a connecting portion T. The thickness of the blade forming the cutting portion C is generally about 0.25 to 0.4 mm. Here, the cutting portion C is formed by a blade with a thickness exceeding 0.4 mm and being 1 mm or less. Thus, as described later, when the user cuts the connecting portion T to connect adjacent cutting portions C and cut each cut-in line, clear unevenness is formed at the cutting portion (including not only the portion of the connecting portion T cut by the user but also the portion of the cutting portion C previously cut by the blade). Even if the user slides a finger or the like along the cut cut-in line, since the contact distance with the cutting portion becomes shorter (even if a finger or the like that touches the protruding portion facing the user slides, it is separated from the next concave portion and does not contact), the risk of the user being cut at the cutting portion can be reduced.

[0053] The crease 26 is in a straight line connecting the other end 22b of the cut line 22 and the other end 23b of the cut line 23, and is parallel to the ridge line 18 and the cut line 21. The crease 26 can be formed by printing a straight line on the upper surface portion 11, or can also be formed only as a straight line connecting the other end 22b and the other end 23b without using special visualization such as printing, but it is desirable to form it by indentation processing or the like so as to be easily bent.

[0054] In order to take out the paper towel P from the storage box 1, the user cuts the connection part T of the cut lines 21, 22, 23, 24, and 25 to connect the adjacent cutting parts C, and cuts the cut lines 21, 22, 23, 24, and 25, thereby forming cut slits along the cut lines 21, 22, 23, 24, and 25 in the take-out port forming part 17. As Figure 5 shown, the part of the upper surface portion 11 surrounded by the cut lines 21, 24, and 25 stands up under the action of the restoring force of the bent paper (the restoring force (elastic force generated by the ridge line 18) that wants to return to the unbent state), and the standing piece 31 is formed by the standing part.

[0055] Next, the user bends the part of the upper surface portion 11 surrounded by the cut lines 21, 22, and 23 upward along the crease 26, and forms a bent piece 32 extending obliquely upward (upward and forward) from the crease 26 by this part. A gap communicating with the inside of the main body 10 is formed between the bent piece 32 and the standing piece 31, and this gap becomes the take-out port 33. The take-out port 33 is different from the take-out port of a general paper towel storage box, and no plastic film is provided, which helps to reduce the waste of plastics.

[0056] In the storage box 1 of the present embodiment, the take-out port forming part 17 has: a cut line 21 provided near the ridge line 18 where the upper surface portion 11 and the front surface portion 13 intersect; a cut line 22 having one end 22a at the left end 21a of the cut line 21 and the other end 22b provided inside the upper surface portion 11; a cut line 23 having one end 23a at the right end 21b of the cut line 21 and the other end 23b provided inside the upper surface portion 11; and a crease 26 connecting the other end 22b of the cut line 22 and the other end 23b of the cut line 23. By cutting the cut lines 21, 22, and 23, a part of the upper surface portion 11 is bent upward along the crease 26 to form a bent piece 32, thereby forming the take-out port 33. Therefore, the bent piece 32 is located above the take-out port 33, and dust is difficult to enter the main body 10.

[0057] In addition, when taking out the paper towel P from above, if the take-out angle of the paper towel P ( Figure 5The θ P ) is the bending angle of the bending piece 32( Figure 5 If the θ is less than the bending angle of the bending piece 32, the bending piece 32 will not substantially hinder the extraction of the paper towel P. Even if the extraction angle is greater than the bending angle, the bending piece 32 will appropriately deform in the direction of increasing the bending angle and guide the extraction of the paper towel P (serve as a guide for the extraction of the paper towel P). Therefore, according to the storage box 1, it is easy to extract the paper towel P from above, and the frictional force during extraction can also be suppressed.

[0058] Moreover, in the storage box 1, the main body 10 is made of paper. The upper surface portion 11 and the front surface portion 13 are divided by bending the paper. The cut line 21 is provided near the ridge line 18 on the upper surface portion 11. The outlet forming portion 17 has: a cut line 24 with one end 24a being the left end 21a of the cut line 21 and the other end 24b being provided on the ridge line 18; and a cut line 25 with one end 25a being the right end 21b of the cut line 21 and the other end 25b being provided on the ridge line 18. By cutting the cut line 24, the cut line 25, and the cut line 21 together, a part of the upper surface portion 11 stands up upward along the ridge line 18 to form the standing piece 31. Therefore, even if the paper towel P exposed from the outlet 33 tends to droop near the front surface portion 13, the standing piece 31 will support it from below, which helps to facilitate the extraction of the paper towel P from above.

[0059] (Second Embodiment)

[0060] Figure 6 The second embodiment of the article storage box of the present invention is shown. The storage box 2 of this embodiment has the same structure as the storage box 1 except that the cut lines 41 and 42 are provided instead of the cut lines 22 and 23, and the bending piece 34 (refer to Figure 7 ) is formed instead of the bending piece 32.

[0061] One end 41a of the cut line 41 is the left end 21a of the cut line 21, and the other end 41b is provided at a position to the left of the one end 41a inside the upper surface portion 11. The cut line 41 is in a wave shape (protruding shape) with concave portions 41c that are repeatedly recessed to the left and convex portions 41d that protrude to the right. The concave portions 41c and the convex portions 41d are in the shape of rounded corners without corners. If the distance in the front-rear direction from the one end 41a to the other end 41b is set as d3, then d3 is preferably 5 to 30 mm, and more preferably 5 to 20 mm.

[0062] The cut-in line 42 has one end 42a at the right end 21b of the cut-in line 21, and the other end 42b is provided inside the upper surface portion 11 at a position to the right of the one end 42a. The cut-in line 42 has a wavy shape with recessed portions 42c that are recessed to the right and protruding portions 42d that are protruding to the left repeatedly provided, and the recessed portions 42c and the protruding portions 42d have a shape with rounded corners without angles. The distance in the front-rear direction from the one end 42a to the other end 42b is the same as that of the cut-in line 41, which is d3, preferably 5 to 30 mm, and more preferably 5 to 20 mm.

[0063] The cut-in line 41 and the cut-in line 42 are formed by dotted lines including a cutting portion C and a connecting portion T (refer to Figure 4 ).

[0064] The crease 26 is in a straight line connecting the other end 41b of the cut-in line 41 and the other end 42b of the cut-in line 42, and is parallel to the ridge line 18 and the cut-in line 21 (the distance from the cut-in line 21 to the crease 26 is d3). In the storage box 2, the crease 26 can also be formed by printing a straight line on the upper surface portion 11, or can also be formed only as a straight line connecting the other end 41b and the other end 42b without being particularly visualized using printing or the like. However, if the length of the cut-in line 21 in the storage box 2 is the same as that of the cut-in line 21 in the storage box 1, the length of the crease 26 in the storage box 2 is longer than that of the crease 26 in the storage box 1. Therefore, in the storage box 2, forming the crease 26 by means of indentation processing or the like is more helpful for the ease of bending compared to the storage box 1.

[0065] When the user wants to take out the tissue paper P from the storage box 2, the user bends the portion of the upper surface portion 11 surrounded by the cut-in line 21, the cut-in line 41, and the cut-in line 42 upward along the crease 26. Then, as Figure 7 shown, a bent piece 34 that extends obliquely upward (upward and forward) from the crease 26 is formed by using this portion. The bent piece 34 has convex portions 34a corresponding to the recessed portions 41c of the cut-in line 41 or the recessed portions 42c of the cut-in line 42, and concave portions 34b corresponding to the protruding portions 41d of the cut-in line 41 or the protruding portions 42d of the cut-in line 42. A gap communicating with the inside of the main body 10 is formed between the bent piece 34 and the erected piece 31, and this gap serves as the take-out port 33. The take-out port 33 is different from the take-out port of a general tissue storage box, and no plastic film is provided, which helps to reduce the waste of plastics.

[0066] In the storage box 2 of the present embodiment, since the cut lines 41 and 42 are wavy, the convex portion 34a of the bent piece 34 is caught at the portion of the concave portion 41c of the cut line 41 or the concave portion 42c of the cut line 42, or the concave portion 34b is caught at the portion of the convex portion 41d of the cut line 41 or the convex portion 42d of the cut line 42, so that the bent piece 34 can be easily maintained at a desired bending angle. Thus, it is easy to adjust the ease of taking out the paper towel P, suppress the frictional force during taking out, and prevent dust from entering the main body 10.

[0067] In addition, the paper towel P exposed from the take-out port 33 is caught at the portion of the concave portion 41c or the concave portion 42c, and its sagging is suppressed, so that it is easy to take out the paper towel P from above. Here, in particular, the other end 41b of the cut line 41 is provided at a position to the left of the one end 41a, the other end 42b of the cut line 42 is provided at a position to the right of the one end 42a, and the crease 26 is parallel to the ridge line 18. Therefore, the take-out port 33 formed on the upper surface portion 11 becomes narrower toward the front (front), and the paper towel P is easily caught at the portion of the concave portion 41c or the concave portion 42c.

[0068] In contrast, the portions of the convex portions 41d and 42d are in the shape of a rounded corner without an angle, so they are not easily caught when taking out the paper towel P, and the user can smoothly take out the paper towel P.

[0069] (Third Embodiment)

[0070] Figure 8 and Figure 9 FIG. shows a third embodiment of the article storage box of the present invention. The storage box 3 of the present embodiment has the same structure as the storage box 1 except for the following points: cut lines 51, 52, and 53 are provided instead of the cut lines 21, 22, and 23, a bent piece 35 (see Figure 10 ) is formed instead of the bent piece 32, the cut lines 24 and 25 are not provided, and the cut lines 61, 62, 63, 64, 65, 66, the creases 67, 68, and 69 are provided.

[0071] Specifically, the take-out port forming portion 17 has a linear cut line 51 along the ridge line 18 on the ridge line 18. In addition, the take-out port forming portion 17 has cut lines 52, 53, and the crease 26 on the upper surface portion 11, and cut lines 61, 62, 63, 64, 65, 66, the creases 67, 68, and 69 on the front surface portion 13.

[0072] The cut line 52 has one end 52a at the left end 51a of the cut line 51, and the other end 52b is provided inside the upper surface portion 11 at a position to the left of the one end 52a. The cut line 52 has a wavy shape with recesses 52c that are repeatedly recessed to the left and protrusions 52d that protrude to the right, and the recesses 52c and the protrusions 52d have a shape with rounded corners without angles. If the distance from the ridge line 18 to the other end 52b (the distance in the front - rear direction from the one end 52a to the other end 52b) is set as d4, then d4 is preferably 6 to 35 mm, and more preferably 6 to 22 mm.

[0073] The cut line 53 has one end 53a at the right end 51b of the cut line 51, and the other end 53b is provided inside the upper surface portion 11 at a position to the right of the one end 53a. The cut line 53 has a wavy shape with recesses 53c that are repeatedly recessed to the right and protrusions 53d that protrude to the left, and the recesses 53c and the protrusions 53d have a shape with rounded corners without angles. The distance from the ridge line 18 to the other end 53b (the distance in the front - rear direction from the one end 53a to the other end 53b) is the same as d4 for the cut line 52, preferably 6 to 35 mm, and more preferably 6 to 22 mm.

[0074] The cut lines 51, 52, and 53 are formed by dotted lines including a cutting portion C and a connecting portion T (refer to Figure 4 ).

[0075] The crease 26 is in a straight - line shape connecting the other end 52b of the cut line 52 and the other end 53b of the cut line 53, and is parallel to the ridge line 18 and the cut line 51. In the storage box 3, the crease 26 can also be formed by printing a straight line on the upper surface portion 11, or can also be formed only as a straight line connecting the other end 52b and the other end 53b without being particularly visualized using printing, etc. However, if the length of the cut line 51 in the storage box 3 is the same as the cut line 21 in the storage box 1, then the length of the crease 26 in the storage box 3 is longer than the crease 26 in the storage box 1. Therefore, in the storage box 3, forming the crease 26 using indentation processing, etc. is more helpful for ease of bending compared to the storage box 1.

[0076] The cut line 61 has the upper end 61a at the left end 51a of the cut line 51, and the lower end 61b is provided inside the front surface portion 13 (that is, on the side away from the ridge line 18 and closer to the central portion of the front surface portion 13). The lower end 61b is located on a straight line extending in a direction orthogonal to the ridge line 18 from the upper end 61a, and the cut line 61 is in a straight - line shape orthogonal 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 set as d5, then d5 is preferably 1 to 7 mm, and more preferably 2 to 5 mm.

[0077] The cutting line 62 has the right end 51b of the cutting line 51 as its upper end 62a, and its lower end 62b is provided inside the front surface portion 13. The lower end 62b is located on a straight line extending from the upper end 62a in a direction orthogonal to the ridge line 18, and the cutting line 62 is in a straight line shape orthogonal to the ridge line 18. The length of the cutting line 62 (the distance from the upper end 62a to the lower end 62b) is the same as that of the cutting line 61, which is d5, preferably 1 to 7 mm, and more preferably 2 to 5 mm.

[0078] The cutting line 63 has the lower end 61b of the cutting line 61 as its upper end 63a, and its lower end 63b is provided below the cutting line 61. The lower end 63b is located on a straight line extending from the upper end 63a in a direction orthogonal to the ridge line 18, and the cutting line 63 is in a straight line shape continuous with the cutting line 61. If the length of the cutting line 63 (the distance from the upper end 63a to the lower end 63b) is set as d6, then d6 is preferably 1 to 7 mm, and more preferably 2 to 5 mm.

[0079] The cutting line 64 has the lower end 62b of the cutting line 62 as its upper end 64a, and its lower end 64b is provided below the cutting line 62. The lower end 64b is located on a straight line extending from the upper end 64a in a direction orthogonal to the ridge line 18, and the cutting line 64 is in a straight line shape continuous with the cutting line 62. The length of the cutting line 64 (the distance from the upper end 64a to the lower end 64b) is the same as that of the cutting line 63, which is d6, preferably 1 to 7 mm, and more preferably 2 to 5 mm.

[0080] The cutting line 65 has the lower end 63b of the cutting line 63 as its upper end 65a, and its lower end 65b is provided below the cutting line 63. The lower end 65b is located on a straight line extending from the upper end 65a in a direction orthogonal to the ridge line 18, and the cutting line 65 is in a straight line shape continuous with the cutting line 63. If the length of the cutting line 65 (the distance from the upper end 65a to the lower end 65b) is set as d7, then d7 is preferably 1 to 7 mm, and more preferably 2 to 5 mm.

[0081] The cutting line 66 has the lower end 64b of the cutting line 64 as its upper end 66a, and its lower end 66b is provided below the cutting line 64. The lower end 66b is located on a straight line extending from the upper end 66a in a direction orthogonal to the ridge line 18, and the cutting line 66 is in a straight line shape continuous with the cutting line 64. The length of the cutting line 66 (the distance from the upper end 66a to the lower end 66b) is the same as that of the cutting line 65, which is d7, preferably 1 to 7 mm, and more preferably 2 to 5 mm.

[0082] The cutting lines 61, 62, 63, 64, 65, and 66 are formed by dotted lines including a cutting portion C and a connecting portion T (refer to Figure 4)。In addition, on the side of the cut-in line 61 of the cut-in line 63 (the boundary portion between the cut-in line 61 and the cut-in line 63), the side of the cut-in line 62 of the cut-in line 64 (the boundary portion between the cut-in line 62 and the cut-in line 64), the side of the cut-in line 63 of the cut-in line 65 (the boundary portion between the cut-in line 63 and the cut-in line 65), and the side of the cut-in line 64 of the cut-in line 66 (the boundary portion between the cut-in line 64 and the cut-in line 66), the connecting portion T is formed longer than the other connecting portions T.

[0083] The crease 67 is in a straight line connecting the lower end 61b of the cut-in line 61 and the lower end 62b of the cut-in line 62, and is parallel to the ridge line 18 and the cut-in line 51. The crease 67 can be formed by printing a straight line on the front surface portion 13, or can also be formed only as a straight line connecting the lower end 61b and the lower end 62b without being particularly visualized using printing or the like, but is preferably formed by indentation processing or the like to be easily bent.

[0084] The crease 68 is in a straight line connecting the lower end 63b of the cut-in line 63 and the lower end 64b of the cut-in line 64, and is parallel to the crease 67. The crease 68 can be formed by printing a straight line on the front surface portion 13, or can also be formed only as a straight line connecting the lower end 63b and the lower end 64b without being particularly visualized using printing or the like, but is preferably formed by indentation processing or the like to be easily bent.

[0085] The crease 69 is in a straight line connecting the lower end 65b of the cut-in line 65 and the lower end 66b of the cut-in line 66, and is parallel to the crease 68. The crease 69 can be formed by printing a straight line on the front surface portion 13, or can also be formed only as a straight line connecting the lower end 65b and the lower end 66b without being particularly visualized using printing or the like, but is preferably formed by indentation processing or the like to be easily bent.

[0086] When the user desires to take out the paper towel P from the storage box 3, the user cuts the connecting portion T of the cut-in lines 51, 52, and 53 to connect the adjacent cutting portions C, and cuts into the cut-in lines 51, 52, and 53, thereby forming a slit at the take-out port forming portion 17 along the cut-in lines 51, 52, and 53.

[0087] Next, the user bends the portion of the upper surface portion 11 surrounded by the cut-in lines 51, 52, and 53 upward along the crease 26, and uses this portion to form a bent piece 35 extending obliquely upward (upward and forward) from the crease 26. The bent piece 35 has a convex portion 35a corresponding to the concave portion 52c of the cut-in line 52 or the concave portion 53c of the cut-in line 53 and a concave portion 35b corresponding to the convex portion 52d of the cut-in line 52 or the convex portion 53d of the cut-in line 53 (refer to Figure 10)。A gap that communicates with the interior of the main body 10 is formed between the bent piece 35 and the ridge line 18 (the upper edge of the front portion 13), and this gap serves as the take-out port 33. The take-out port 33 is different from the take-out ports of ordinary paper towel storage boxes in that no plastic film is provided, which helps reduce waste plastics.

[0088] In the storage box 3, in order to more easily take out the paper towel P, the take-out port 33 can be enlarged.

[0089] At this time, the user forms the bent piece 35, cuts off the connecting portion T of the cut lines 61 and 62 to connect the adjacent cutting portions C, and cuts the cut lines 61 and 62, so that cut slits are formed in the take-out port forming portion 17 along the cut lines 61 and 62. Moreover, as Figure 10 shown, when the user bends the portion of the front portion 13 surrounded by the cut lines 61 and 62 forward along the crease 67, and forms a bent piece 36 extending obliquely forward (forward and upward) from the crease 67 using this portion, the gap formed between the bent piece 36 and the bent piece 35 becomes the enlarged take-out port 33.

[0090] In the storage box 3, when the remaining amount of the paper towel P decreases and the stacked height thereof becomes lower, the user cuts off the connecting portion T of the cut lines 63 and 64 to connect the adjacent cutting portions C, and cuts the cut lines 63 and 64, so that cut slits are formed in the take-out port forming portion 17 along the cut lines 63 and 64, and the portion of the front portion 13 surrounded by the cut lines 63 and 64 can be bent forward along the crease 68. Thereby, the bent piece 36 expands downward and the take-out port 33 expands, making it easy to take out the paper towel P.

[0091] When the remaining amount of the paper towel P further decreases, the user cuts off the connecting portion T of the cut lines 65 and 66 to connect the adjacent cutting portions C, and cuts the cut lines 65 and 66, so that cut slits are formed in the take-out port forming portion 17 along the cut lines 65 and 66, and the portion of the front portion 13 surrounded by the cut lines 65 and 66 can be bent forward along the crease 69. Thereby, as Figure 11 shown, the bent piece 36 further expands downward and the take-out port 33 expands, making it easy to take out the paper towel P with a further reduced remaining amount.

[0092] In the storage box 3 of the present embodiment, the take-out port forming portion 17 has: a cut line 51 provided on the ridge line 18 where the upper surface portion 11 and the front surface portion 13 intersect; a cut line 52 having one end 52a at the left end 51a of the cut line 51 and the other end 52b provided inside the upper surface portion 11; a cut line 53 having one end 53a at the right end 51b of the cut line 51 and the other end 53b provided inside the upper surface portion 11; and a crease 26 that connects the other end 52b of the cut line 52 and the other end 53b of the cut line 53. By cutting the cut line 51, the cut line 52, and the cut line 53, a part of the upper surface portion 11 is bent upward along the crease 26 to form a bent piece 35, thereby forming the take-out port 33. Therefore, the bent piece 35 is located above the take-out port 33, and dust is difficult to enter the main body 10.

[0093] In addition, when taking out the paper towel P from above, if the take-out angle of the paper towel P is less than or equal to the bending angle of the bent piece 35, the bent piece 35 will not substantially hinder the take-out of the paper towel P. Even if the take-out angle is greater than the bending angle, the bent piece 35 will appropriately deform in the direction of increasing the bending angle and guide the take-out of the paper towel P. Therefore, according to the storage box 3, it is easy to take out the paper towel P from above, and the frictional force during take-out can also be suppressed.

[0094] In the storage box 3, since the cut line 52 and the cut line 53 are wavy, the convex portion 35a of the bent piece 35 is caught at the concave portion 52c of the cut line 52 or the concave portion 53c of the cut line 53, or the concave portion 35b is caught at the convex portion 52d of the cut line 52 or the convex portion 53d of the cut line 53, so that it is easy to maintain the bent piece 35 at a desired bending angle. Thus, it is easy to adjust the ease of taking out the paper towel P, suppressing the frictional force during take-out, and preventing dust from entering the main body 10.

[0095] In addition, the paper towel P exposed from the take-out port 33 is caught at the concave portion 52c or the concave portion 53c, and its sagging is suppressed, so it is easy to take out the paper towel P from above. Here, in particular, the other end 52b of the cut line 52 is provided at a position to the left of the one end 52a, the other end 53b of the cut line 53 is provided at a position to the right of the one end 53a, and the crease 26 is parallel to the ridge line 18. Therefore, the take-out port 33 formed on the upper surface portion 11 becomes narrower towards the front, and the paper towel P is easily caught at the concave portion 52c or the concave portion 53c.

[0096] In contrast, the convex portions 52d and 53d are in the shape of a fillet without corners, so they are not easily caught when taking out the paper towel P, and the user can smoothly take out the paper towel P.

[0097] In the storage box 3, the take-out port forming portion 17 has: a cut line 61, which has the left end 51a of the cut line 51 as its upper end 61a and the lower end 61b is provided inside the front portion 13; a cut line 62, which has the right end 51b of the cut line 51 as its upper end 62a and the lower end 62b is provided inside the front portion 13; and a crease 67, which connects the lower end 61b of the cut line 61 and the lower end 62b of the cut line 62, cuts the cut line 61 and the cut line 62 together with the cut line 51, and bends a part of the front portion 13 forward along the crease 67 to form a bent piece 36. Therefore, especially when the stacked height of the paper towels P is slightly lower and away from the upper surface portion 11, the paper towels P can be easily taken out.

[0098] Moreover, the take-out port forming portion 17 has: a cut line 63, which has the lower end 61b of the cut line 61 as its upper end 63a and the lower end 63b is provided below the cut line 61; a cut line 64, which has the lower end 62b of the cut line 62 as its upper end 64a and the lower end 64b is provided below the cut line 62; and a crease 68, which connects the lower end 63b of the cut line 63 and the lower end 64b of the cut line 64. By cutting the cut line 63 and the cut line 64, a part of the front portion 13 is bent forward along the crease 68, thereby expanding the bent piece 36. Therefore, when the remaining amount of the paper towels P decreases, the paper towels P can be easily taken out.

[0099] Furthermore, even when the remaining amount of the paper towels P further decreases, the take-out port forming portion 17 has: a cut line 65, which has the lower end 63b of the cut line 63 as its upper end 65a and the lower end 65b is provided below the cut line 63; a cut line 66, which has the lower end 64b of the cut line 64 as its upper end 66a and the lower end 66b is provided below the cut line 64; and a crease 69, which connects the lower end 65b of the cut line 65 and the lower end 66b of the cut line 66. By cutting the cut line 65 and the cut line 66, a part of the front portion 13 is bent forward along the crease 69, thereby also expanding the bent piece 36. Therefore, the paper towels P with a small remaining amount can also be easily taken out.

[0100] 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 orthogonal 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 orthogonal 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 orthogonal to the ridge line 18, 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 orthogonal to the ridge line 18, the lower end 65b of the cut line 65 is provided on a straight line extending from the upper end 65a of the cut line 65 in a direction orthogonal to the ridge line 18, the lower end 66b of the cut line 66 is provided on a straight line extending from the upper end 66a of the cut line 66 in a direction orthogonal to the ridge line 18. The creases 67, 68, and 69 are parallel to the ridge line 18. Therefore, the downward expansion of the folding piece 36 and the downward enlargement of the take-out port 33 are carried out with equal width in the left-right direction, and the ease of taking out is maintained regardless of the remaining amount of the paper towel P.

[0101] In addition, the cut lines 61, 62, 63, 64, 65, and 66 are formed by dotted lines including a cutting part C and a connecting part T. The connecting parts T located on the cut line 61 side of the cut line 63, the cut line 62 side of the cut line 64, the cut line 63 side of the cut line 65, and the cut line 64 side of the cut line 66 are formed longer than the other connecting parts T. Therefore, when first cutting the dotted lines of the cut lines 61 and 62 to cut the cut lines 61 and 62, it is possible to prevent this cutting from accidentally proceeding to the cut lines 63 and 64. When next cutting the dotted lines of the cut lines 63 and 64 to cut the cut lines 63 and 64, it is possible to prevent this cutting from accidentally proceeding to the cut lines 65 and 66.

[0102] (Fourth Embodiment)

[0103] Figure 12 and Figure 13 The fourth embodiment of the article storage box representing the present invention is shown. The storage box 4 of this embodiment has the same structure as the storage box 1 except for the following points: a cut line 71 is provided from the bottom surface part 12 to the back surface part 14, a crease 72 is provided on the back surface part 14, a cut line 81 and a crease 82 are provided on the front surface part 13, and the main body 10 can be deformed into a state where the bottom is raised.

[0104] The cutting line 71 is formed along a continuous line from the bottom surface portion 12 to the back surface portion 14. The cutting line 71 includes a bottom surface cutting portion 73, a bottom surface cutting portion 74, a bottom surface cutting portion 75, a back surface cutting portion 76, and a back surface cutting portion 77. The bottom surface cutting portion 73, the bottom surface cutting portion 74, and the bottom surface cutting portion 75 are formed on the bottom surface portion 12. The back surface cutting portion 76 and the back surface cutting portion 77 are formed on the back surface portion 14. The bottom surface cutting portion 73, the bottom surface cutting portion 74, the bottom surface cutting portion 75, the back surface cutting portion 76, and the back surface cutting portion 77 are all straight.

[0105] The bottom surface cutting portion 73 and the bottom surface cutting portion 74 extend from the ridge line 19 where the bottom surface portion 12 and the back surface portion 14 intersect toward the front surface portion 13. The bottom surface cutting portion 73 and the bottom surface cutting portion 74 are orthogonal to the ridge line 19. The bottom surface cutting portion 75 connects the bottom surface cutting portion 73 and the bottom surface cutting portion 74. Specifically, the bottom surface cutting portion 75 connects one end 73a of the bottom surface cutting portion 73 and one end 74a of the bottom surface cutting portion 74. One end 73a of the bottom surface cutting portion 73 and one end 74a of the bottom surface cutting portion 74 are located in the middle portion of the bottom surface portion 12. Here, the middle portion of the bottom surface portion 12 refers to the portion of the bottom surface portion 12 other than the edges (the boundaries with the front surface portion 13, the back surface portion 14, the left side surface portion 15, and the right side surface portion 16). The bottom surface cutting portion 75 extends parallel to the ridge line 19.

[0106] The back surface cutting portion 76 is continuous with the bottom surface cutting portion 73, and the back surface cutting portion 77 is continuous with the bottom surface cutting portion 74. That is, the lower end 76b of the back surface cutting portion 76 is connected to the other end 73b of the bottom surface cutting portion 73, and the lower end 77b of the back surface cutting portion 77 is connected to the other end 74b of the bottom surface cutting portion 74. The back surface cutting portion 76 and the back surface cutting portion 77 extend in the height direction (up and down direction) of the main body 10. The upper end 76a of the back surface cutting portion 76 and the upper end 77a of the back surface cutting portion 77 are located in the middle portion of the back surface portion 14. Here, the middle portion of the back surface portion 14 refers to the portion of the back surface portion 14 other than the edges (the boundaries with the upper surface portion 11, the bottom surface portion 12, the left side surface portion 15, and the right side surface portion 16).

[0107] The cutting line 71 (the bottom surface cutting portion 73, the bottom surface cutting portion 74, the bottom surface cutting portion 75, the back surface cutting portion 76, and the back surface cutting portion 77) is formed by a dotted line including a cutting portion C and a connecting portion T (refer to Figure 4 ).

[0108] The crease 72 is in a straight line connecting the upper end 76a of the back cut portion 76 and the upper end 77a of the back cut portion 77, and is parallel to the ridge line 19. The crease 72 can be formed by printing a straight line on the back surface portion 14, or can also be formed only as a straight line connecting the upper end 76a and the upper end 77a without being particularly visualized using printing or the like. However, it is preferably formed by indentation processing or the like so as to be easily bent.

[0109] In the bottom surface portion 12 and the back surface portion 14, the portion surrounded by the bottom cut portion 73, the bottom cut portion 74, the bottom cut portion 75, the back cut portion 76, the back cut portion 77, and the crease 72 is the tongue portion 91 of the tongue piece 101 that is connected to the middle portion of the back surface portion 14 in a state where a slit is formed in the main body 10 along the cut line 71. The tongue piece 101 is formed of a single plate including a part of the bottom surface portion 12 and a part of the back surface portion 14. In the present embodiment, the tongue piece 101 is rectangular. The crease 72 is used to bend the tongue piece 101 toward the front surface portion 13 and is provided at a height position substantially the same as that of the slit portion 92 described later.

[0110] The cut line 81 is formed in the front surface 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 straight lines.

[0111] The horizontal cut portion 83 is located in the middle portion of the front surface portion 13, extends in the left - right direction of the main body 10, and is parallel to the ridge line 18. Here, the middle portion of the front surface portion 13 refers to the portion of the front surface portion 13 other than the edges (the boundaries with the upper surface portion 11, the bottom surface portion 12, the left side surface portion 15, and the right side surface portion 16).

[0112] The vertical cut portions 84, 85, 86, and 87 extend upward from the horizontal cut portion 83. The vertical cut portions 84, 85, 86, and 87 are arranged in order from the left end 83a to the right end 83b of the horizontal cut portion 83.

[0113] Specifically, the vertical cut portion 84 extends along the height direction of the main body 10 in such a manner that the lower end 84b is provided at the left end 83a of the horizontal cut portion 83 and the upper end 84a is provided above the left end 83a. If the length of the vertical cut portion 84 (the distance from the upper end 84a to the lower end 84b) is set as d8, then d8 is preferably 1 to 15 mm, and more preferably 2 to 10 mm.

[0114] The vertical cutting portion 87 extends along the height direction of the main body 10 in such a manner that the lower end 87b is provided at the right end 83b of the horizontal cutting portion 83 and the upper end 87a is provided above the right end 83b. The length of the vertical cutting portion 87 (the distance from the upper end 87a to the lower end 87b) is the same as that of the vertical cutting portion 84, which is d8, preferably 1 to 15 mm, and more preferably 2 to 10 mm.

[0115] The vertical cutting portion 85 extends obliquely with respect to the height direction of the main body 10 in such a manner that the lower end 85b is provided at the middle portion 83c of the horizontal cutting portion 83 and the upper end 85a is provided above and to the left of the middle portion 83c.

[0116] The vertical cutting portion 86 extends obliquely with respect to the height direction of the main body 10 in such a manner that the lower end 86b is provided at the middle portion 83d between the middle portion 83c and the right end 83b of the horizontal cutting portion 83, and the upper end 86a is provided above and to the right of the middle portion 83d. The vertical cutting portion 86 is line-symmetric with the vertical cutting portion 85 with respect to the vertical line passing through the center in the left-right direction of the front portion 13.

[0117] The cutting line 81 (the horizontal cutting portion 83, the vertical cutting portion 84, the vertical cutting portion 85, the vertical cutting portion 86, and the vertical cutting portion 87) is formed by a dotted line including a cutting portion C and a connecting portion T (see Figure 4 ).

[0118] The crease 82 is in a straight line connecting the upper end 84a of the vertical cutting portion 84 and the upper end 87a of the vertical cutting portion 87, and is parallel to the ridge line 18. The crease 82 includes: a left portion 82a that connects the upper end 84a of the vertical cutting portion 84 and the upper end 85a of the vertical cutting portion 85; a central portion 82b that connects the upper end 85a of the vertical cutting portion 85 and the upper end 86a of the vertical cutting portion 86; and a right portion 82c that connects the upper end 86a of the vertical cutting portion 86 and the upper end 87a of the vertical cutting portion 87. The crease 82 can be formed by printing a straight line on the front portion 13, or can be formed only as a straight line connecting the upper end 84a and the upper end 87a without being particularly visualized using printing or the like, but is preferably formed by indentation processing or the like to be easily bent.

[0119] The left part 82a of the crease 82 is used to bend the part surrounded by the horizontal cut portion 83, the vertical cut portion 84, and the vertical cut portion 85. By bending this part forward (outside the main body 10), a bent piece 93 is formed. The central part 82b of the crease 82 is used to bend the part surrounded by the horizontal cut portion 83, the vertical cut portion 85, and the vertical cut portion 86. By bending this part backward (inside the main body 10), a bent piece 94 is formed. The right part 82c of the crease 82 is used to bend the part surrounded by the horizontal cut portion 83, the vertical cut portion 86, and the vertical cut portion 87. By bending this part forward, a bent piece 95 is formed (see Figure 14 ).

[0120] In the front part 13, the part surrounded by the horizontal cut portion 83, the vertical cut portion 84, the vertical cut portion 87, and the crease 82 is a slit part 92 located in the middle part of the front part 13 and serving as a slit 102 into which the tongue piece 101 can be inserted. The slit 102 is a horizontally long opening extending parallel to the ridge line 18 and includes the bent piece 93, the bent piece 94, and the bent piece 95. The tongue piece 101 is configured to contact the lower edges of the bent piece 93, the bent piece 94, and the bent piece 95 and be parallel to the bottom part 12 in a state of being inserted into the slit 102.

[0121] Next, an example of a method for deforming the main body 10 will be described. First, a cut slit is formed in the main body 10 along the cut line 81. After that, along the left part 82a of the crease 82, the part surrounded by the horizontal cut portion 83, the vertical cut portion 84, and the vertical cut portion 85 is bent forward to form the bent piece 93. Along the central part 82b of the crease 82, the part surrounded by the horizontal cut portion 83, the vertical cut portion 85, and the vertical cut portion 86 is bent backward to form the bent piece 94. Along the right part 82c of the crease 82, the part surrounded by the horizontal cut portion 83, the vertical cut portion 86, and the vertical cut portion 87 is bent forward to form the bent piece 95, thereby making the slit part 92 into the slit 102.

[0122] Next, a cut slit is formed in the main body 10 along the cut line 71, thereby making the tongue piece part 91 into the tongue piece 101. By bending the tongue piece 101 along the crease 72 toward the front part 13 while inserting it into the slit 102 as shown in Figure 14 and Figure 15 , the main body 10 can be deformed into a state in which the tongue piece 101 is inserted into the slit 102.

[0123] In the deformed main body 10, the paper towel P is placed on the tongue piece 101. By raising the bottom of the bottom surface portion 12 of the main body 10 in this way to bring the paper towel P closer to the upper surface portion 11, even if the remaining amount of the paper towel P becomes less, the paper towel P can be smoothly taken out from the take-out port 33. At this time, the distance from the tongue piece 101 to the upper surface portion 11 is preferably 3 cm or more and 6 cm or less. In addition, in Figure 14 and Figure 15 the illustration of the paper towel P is omitted.

[0124] In the storage box 4 of the present embodiment, the main body 10 has: a cut line 71 formed from the bottom surface portion 12 to the back surface portion 14; a cut line 81 formed on the front surface portion 13; a tongue piece portion 91 which becomes a tongue piece 101 connected to the middle portion of the back surface portion 14 in a state where the cut line 71 is cut; and a slit portion 92 which becomes a slit 102 located in the middle portion of the front surface portion 13 and into which the tongue piece 101 can be inserted in a state where the cut line 81 is cut. By inserting the tongue piece 101 into the slit 102, the tongue piece 101 can be spanned from the middle portion of the back surface portion 14 to the middle portion of the front surface portion 13. Therefore, when the remaining amount of the paper towel P becomes less, by inserting the tongue piece 101 into the slit 102 in such a manner that the paper towel P is placed on the tongue piece 101, the tongue piece 101 can be brought into surface contact with the paper towel P and the bottom of the storage box 4 can be raised. Thus, there is no need to separately provide a member for raising the bottom with respect to the main body 10, and the paper towel P can be stably supported when the bottom is raised.

[0125] In addition, the cut line 81 has a cut line 83 extending in the left-right direction, and successively has cut lines 84, 85, 86, and 87 extending upward from the cut line 83. The storage box 4 (main body 10) has: a left portion 82a of the crease 82 which connects the upper end 84a of the cut line 84 and the upper end 85a of the cut line 85; a central portion 82b of the crease 82 which connects the upper end 85a of the cut line 85 and the upper end 86a of the cut line 86; and a right portion 82c of the crease 82 which connects the upper end 86a of the cut line 86 and the upper end 87a of the cut line 87. By cutting the cut line 83, the cut line 84, the cut line 85, the cut line 86, and the cut line 87 and bending a part of the front surface portion 13 forward along the left portion 82a of the crease 82, a bent piece 93 is formed, bending a part of the front surface portion 13 backward along the central portion 82b of the crease 82, a bent piece 94 is formed, and bending a part of the front surface portion 13 forward along the right portion 82c of the crease 82, a bent piece 95 is formed. Therefore, as Figure 16As shown, compared with the case where there is no bending piece, the height of the insertion space 103 for the tongue piece 101 in the slit 102 can be increased, making it easier to insert the tongue piece 101. After the insertion of the tongue piece 101 is completed, a downward force is applied to at least one of the bending pieces 93, 94, and 95 so that it contacts the tongue piece 101 more firmly, thereby making it difficult for the tongue piece 101 to fall off from the slit 102. Here, since the bending directions of the bending pieces 93, 94, and 95 are different directions such as forward and backward, it is even more difficult for the tongue piece 101 to fall off from the slit 102. In addition, when the tongue piece 101 is about to tilt during side view observation due to some external force (when trying to change the height in the front and back), the tilt can be prevented at multiple points in the front and back (the lower edges of the bending pieces 93 and 95 in the front, and the lower edge of the bending piece 94 in the back).

[0126] (Embodiment 5)

[0127] Figure 17 This shows the fifth embodiment of the article storage box of the present invention. The storage box 5 of this embodiment has the same structure as the storage box 1 except for the following points: cutting lines 51, 52, and 53 are provided instead of the cutting lines 21, 22, and 23, a crease 27 is provided instead of the crease 26, a bending piece 37 (refer to Figure 19 ) is formed instead of the bending piece 32, and the cutting lines 24 and 25 are not provided.

[0128] Specifically, the outlet forming portion 17 has a linear cutting line 51 along the ridge line 18 at the ridge line 18. In addition, the outlet forming portion 17 has cutting lines 52, 53, and a crease 27 on the upper surface portion 11.

[0129] The cutting line 52 has one end 52a at the left end 51a of the cutting line 51, and the other end 52b is provided inside the upper surface portion 11. The other end 52b is located on a straight line extending in a direction orthogonal to the ridge line 18 from the one end 52a, and the cutting line 52 is in a linear shape orthogonal to the ridge line 18. If the length of the cutting line 52 (the distance from the one end 52a to the other end 52b) is set as d9, then d9 is preferably 5 to 30 mm, and more preferably 5 to 20 mm.

[0130] The cutting line 53 has one end 53a at the right end 51b of the cutting line 51, and the other end 53b is provided inside the upper surface portion 11. The other end 53b is located on a straight line extending in a direction orthogonal to the ridge line 18 from the one end 53a, and the cutting line 53 is in a linear shape orthogonal to the ridge line 18 and parallel to the cutting line 52. The length of the cutting line 53 (the distance from the one end 53a to the other end 53b) is the same as that of the cutting line 52, which is d9, and is preferably 5 to 30 mm, and more preferably 5 to 20 mm.

[0131] The cut-in lines 51, 52, and 53 are formed by dotted lines including a cutting part C and a connecting part T (refer to Figure 4 ).

[0132] The crease 27 is in a curved shape bulging toward the side opposite to the cut-in part 51 that connects the other end 52b of the cut-in line 52 and the other end 53b of the cut-in line 53, and preferably depicts an arc or an elliptical arc. In order to enhance the restoring force acting on the bent piece 37, the curvature rate of the crease 27 is preferably 1.9% or more. If the restoring force is too strong, it may be difficult to take out the article from the take-out port. Therefore, it is preferably 9.7% or less, and more preferably 4.8% or less (refer to International Publication No. 2024 / 117271). Here, the curvature rate is a value reflecting the size of the curve. As Figure 18 shown, when assuming the smallest rectangle R that can accommodate the curve (the crease 27 is illustrated in Figure 18 ), if the distance between the two ends of the curve corresponding to the length of one side of the rectangle R (the long side in Figure 18 ) is set as r1, and the distance from this side to the vertex of the curve corresponding to the length of the other side of the rectangle R (the short side in Figure 18 ) is set as r2, then the curvature rate 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. The crease 27 can be formed by printing a straight line on the upper surface part 11, or can also be formed as a straight line connecting the other end 52b and the other end 53b without being particularly visualized using printing, etc., but it is preferably formed by indentation processing or the like to be easily bent.

[0133] When the user wants to take out the paper towel P from the storage box 5, the user cuts the connecting part T of the cut-in lines 51, 52, and 53 to connect the adjacent cutting parts C, and by cutting the cut-in lines 51, 52, and 53, a slit is formed in the take-out port forming part 17 along the cut-in lines 51, 52, and 53.

[0134] Next, the user bends the part of the upper surface part 11 surrounded by the cut-in lines 51, 52, and 53 upward along the crease 27. As Figure 19 shown, the bent piece 37 extending obliquely upward (upward and forward) from the crease 27 is formed by using this part. A gap communicating with the inside of the main body 10 is formed between the bent piece 37 and the ridge line 18 (the upper edge of the front surface part 13), and this gap becomes the take-out port 33. The take-out port 33 is different from the take-out ports of general paper towel storage boxes, and no plastic film is provided, which helps to reduce the waste of plastics.

[0135] In the storage box 5 of the present embodiment, the crease 27 is a curved shape bulging toward the side opposite to the cut line 51. Therefore, a restoring force (a curve force based on the curvature of the curve) that wants to return to the state before bending easily acts on the bent piece 37 bent along the crease 27, thereby being able to suppress the case where the outlet 33 expands and dust easily enters the main body 10.

[0136] In addition, the cut line 51 is provided on the ridge line 18, the other end 52b of the cut line 52 is provided on a straight line extending from one end 52a in a direction orthogonal to the ridge line 18, and the other end 53b of the cut line 53 is provided on a straight line extending from one end 53a in a direction orthogonal to the ridge line 18. Therefore, the length of the cut line that the user must cut to form the bent piece 37 (and thus the outlet 33) can be shortened, and the cutting itself can be in a straight line shape and is easy to perform, and the operation for taking out the tissue paper P becomes simple.

[0137] The present invention is not limited to the above embodiment, and various modifications can be made. In the above embodiment, as the article stored in the storage box, a tissue paper as a thin sheet paper is exemplified, but it is not limited thereto.

[0138] In addition, of course, even if the crease 26 in the first to fourth embodiments is set to a curved shape like the crease 27 in the fifth embodiment instead of a straight line shape, the cut lines 61, 62, 63, 64, 65, 66, the creases 67, 68, and 69 in the third embodiment, the cut line 71, the crease 72, the cut line 81, and the crease 82 in the fourth embodiment can be provided in the fifth embodiment.

[0139] Each cut line can be cut by any method that does not depend on a dotted line, and the shape (such as a straight line shape, a wavy shape, etc.) and arrangement of the cut line can also be arbitrary. For example, as shown in the storage box 6 in Figure 20 the crease 26 in the first embodiment can be replaced with the crease 27 in the third embodiment, and the cut line 21 is set as a wavy dotted line, and the shortest distance d from the ridge line 18 to the cut line 21 10 is set to 1 to 5 mm, the longest distance d 11 is set to 1 to 10 mm, the length (wavelength) of the waveform is set to 5 to 10 mm, the lengths d2 of the cut lines 22 and 23 are set to 5 to 30 mm, and the distance d corresponding to r2 in Figure 18 is 12Set it to 1 to 5 mm. By making the cutting line wavy in this way, even if the user slides a finger or the like along the cutting line of the cut, since the contact distance with the cutting portion becomes shorter (even if a finger or the like that contacts the top portion of the wave facing the user slides, it is separated from the next bottom portion and does not contact), the risk of the user being cut at the cutting portion can be reduced.

[0140] Moreover, in the fourth embodiment, the tongue piece portion may be formed from the bottom surface portion to the front surface portion instead of from the bottom surface portion to the back surface portion, the slit portion may be formed on the back surface portion instead of the front surface portion, the number of bent pieces of the slit in the fourth embodiment may be more than 4 or two or less (including 0) instead of 3, and the bending directions in the front and rear may be appropriately changed.
