Description

[Technical Field]

[0001] The present invention relates to an item storage box for storing items. [Background technology]

[0002] An example of a conventional storage box is described in Patent Document 1. The storage box described in this document has a box-shaped main body consisting of a bottom, side, and top, and stores a plurality of stacked items (tissue paper). The top is provided with an outlet forming section through which an outlet for the items is formed. The outlet forming section has wavy perforations formed along a center line that divides the top in half in the short direction. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 9-150871 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-described storage box, after making a cut along the perforation, the sections on either side of the cut (the folding pieces) can be folded diagonally upward to form a gap between the folding pieces that serves as an access opening. However, the folded folding pieces naturally return to their original (unfolded) state. As a result, the folding angle of the folding pieces gradually decreases over time, narrowing the gap between the folding pieces (the access opening). If the access opening is too narrow, it becomes difficult to smoothly remove items from the main body.

[0005] The present invention has been made in view of the above-mentioned problems, and has an object to provide an item storage box from which items can be easily and smoothly removed. [Means for solving the problem]

[0006] The item storage box according to the present invention is an item storage box for storing items, and comprises a box-shaped main body having a main surface on which a horizontally elongated outlet forming portion through which an outlet for the item is formed, and the outlet forming portion includes first and second folding pieces that are folded diagonally upward on the main surface along first and second fold lines extending horizontally of the outlet forming portion so that their inner surfaces face each other, the first folding piece has a first convex portion that protrudes toward the second folding piece, and the second folding piece has a second convex portion that protrudes toward the first folding piece, and the first and second convex portions are located on the same straight line parallel to the vertical direction of the outlet forming portion so that the first and second convex portions are in contact with each other when the first and second folding pieces are folded.

[0007] This storage box is provided with first and second folding pieces that are folded diagonally upward along folding lines (first and second folding lines) extending laterally of the outlet-forming section. The first and second folding pieces each have a first and second convex portion, which are located on the same straight line parallel to the vertical direction of the outlet-forming section so that the first and second convex portions are in contact with each other when the first and second folding pieces are folded. Therefore, even if the folded first and second folding pieces attempt to return to their original state, the first and second convex portions can interfere with each other along the way. This prevents the first and second folding pieces from naturally returning to their original state. [Effects of the Invention]

[0008] According to the present invention, an article storage box is realized that allows articles to be easily and smoothly removed from the main body. [Brief explanation of the drawings]

[0010] 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. (First embodiment)

[0011] 1 and 2 are a perspective view and a plan view, respectively, showing a first embodiment of an item storage box according to the present invention. The item storage box 1 is an item storage box for storing items, and includes a main body 10. Examples of items include sanitary paper (tissue paper, toilet paper, paper towels, kitchen paper, etc.), gloves, and masks. In this embodiment, the item storage box 1 (main body 10) stores a plurality of items stacked on top of each other.

[0012] The main body 10 is box-shaped. Specifically, the main body 10 is rectangular. The main body 10 has a main surface 12. The main surface 12 is rectangular in plan view. In this embodiment, the main surface 12 is equivalent to the top surface of the main body 10. However, the item storage box 1 may be used with the main surface 12 facing upward, or with the main surface 12 facing sideways.

[0013] The main surface 12 is provided with a take-out port forming section 20 where an article take-out port is formed. The take-out port forming section 20 has a horizontally long shape. That is, the length of the take-out port forming section 20 in the horizontal direction (left and right direction in FIG. 2) is greater than the length of the take-out port forming section 20 in the vertical direction (up and down direction in FIG. 2). Here, the horizontal and vertical directions of the take-out port forming section 20 are equal to the long side and short side directions of the main surface 12, respectively.

[0014] The outlet forming section 20 includes a folding piece 22 (first folding piece), a folding piece 24 (second folding piece), a crease 32 (first fold line), a crease 34 (second fold line), a cut line 42 (boundary cut line), a cut line 44, and a cut line 46. The folding pieces 22 and 24 are folded diagonally upward from the main surface 12 so that their inner surfaces face each other. In other words, the folding pieces 22 and 24 have a double-door structure. Figures 1 and 2 show the folding pieces 22 and 24 in an unfolded state.

[0015] 3 and 4 are plan views showing the folding piece 22 and the folding piece 24, respectively. The folding piece 22 has a convex portion 26 (first convex portion) that protrudes toward the folding piece 24. The folding piece 24 has a convex portion 28 (second convex portion) that protrudes toward the folding piece 22. As shown in FIG. 5, the convex portion 26 and the convex portion 28 are located on the same straight line (e.g., line L1) that is parallel to the longitudinal direction of the outlet forming portion 20. Here, the convex portion 26 being located on line L1 means that the convex portion 26 and the line L1 share two or more points. The same applies to the convex portion 28. In other words, the convex portion 26 and the convex portion 28 are positioned such that there is a straight line that passes through both the convex portion 26 and the convex portion 28 and is parallel to the longitudinal direction of the outlet forming portion 20. The convex portion 26 and the convex portion 28 are in contact with each other when the folding piece 22 and the folding piece 24 are folded. In this way, the protrusions 26 and 28 are located on the straight line L1 so that the protrusions 26 and 28 are in contact with each other when the bent pieces 22 and 24 are bent.

[0016] The folding piece 22 has a holding portion 22a (first holding portion) and a restricting portion 22b (first restricting portion) (see FIG. 3). The folding piece 22 has one holding portion 22a and multiple restricting portions 22b. The folding piece 24 has a holding portion 24a (second holding portion) and restricting portion 24b (second restricting portion) (see FIG. 4). The folding piece 24 has one holding portion 24a and multiple restricting portions 24b. The holding portion 22a and the holding portion 24a sandwich and hold an article pulled out from the outlet. The holding portion 22a and the holding portion 24a are located on a center line L2 that bisects the main surface 12 in the long side direction. The width w1 of each of the holding portions 22a, 24a is, for example, 7 cm or more and 15 cm or less. The width w2 between each of the holding portions 22a, 24a and one end of the outlet forming portion 20 is, for example, 2 cm or more and 5 cm or less. The width w3 between each of the holding portions 22a, 24a and the other end of the outlet forming portion 20 is, for example, 2 cm or more and 5 cm or less. The widths w2 and w3 may be equal to or different from each other.

[0017] The restricting portions 22b and 24b are provided on both sides of the holding portion 22a and the holding portion 24a, respectively. Specifically, two restricting portions 22b are provided on one side of the holding portion 22a, and one restricting portion 22b is provided on the other side. Similarly, two restricting portions 24b are provided on one side of the holding portion 24a, and one restricting portion 24b is provided on the other side.

[0018] The restricting portion 22b protrudes more toward the crease 34 than the retaining portion 22a. That is, the distance from the restricting portion 22b to the crease 34 is shorter than the distance from the retaining portion 22a to the crease 34. Furthermore, the restricting portion 24b protrudes more toward the crease 32 than the retaining portion 24a. That is, the distance from the restricting portion 24b to the crease 32 is shorter than the distance from the retaining portion 24a to the crease 32. In this embodiment, the restricting portion 22b and the restricting portion 24b reach the crease 34 and the crease 32, respectively. Therefore, the distance from the restricting portion 22b to the crease 34 and the distance from the restricting portion 24b to the crease 32 are both zero.

[0019] The restricting portion 22b and the restricting portion 24b are provided with protrusions 26 and protrusions 28, respectively. The protrusions 26 are formed on a side end portion 22c (first side end portion) of the restricting portion 22b. A plurality of protrusions 26 are formed on one side end portion 22c. Each side end portion 22c has a wavy shape. The protrusions 28 are formed on a side end portion 24c (second side end portion) of the restricting portion 24b. A plurality of protrusions 28 are formed on one side end portion 24c. Each side end portion 24c has a wavy shape. The protrusions 26 are formed on both the side end portion 22c and the side end portion 22d (third side end portion) of the holding portion 22a. The protrusions 28 are formed on both the side end portion 24c and the side end portion 24d (fourth side end portion) of the holding portion 24a. When the folding piece 22 has a plurality of protrusions 26 as in this embodiment, it is sufficient that each protrusion 26 and at least one protrusion 28 are located on the same straight line parallel to the longitudinal direction of the outlet forming section 20. Similarly, when the folding piece 24 has a plurality of protrusions 28, it is sufficient that each protrusion 28 and at least one protrusion 26 are located on the same straight line.

[0020] The restricting portion 22b and the restricting portion 24b may have a shape that imitates a real object. An example of such a real object is a tree. The restricting portion 22b and the restricting portion 24b may be painted with a color or pattern that matches the real object. The color may be changed according to the sales season of the item storage box 1. For example, the color of a tree with green leaves may be painted in spring or summer, the color of a tree with red leaves may be painted in autumn, and the color of a Christmas tree may be painted in winter. In this embodiment, the folding pieces 22 and the folding pieces 24 have congruent shapes and are arranged point-symmetrically.

[0021] The fold line 32 is a fold line for folding the folding piece 22. That is, the folding piece 22 is folded along the fold line 32. The fold line 32 coincides with the rear end of the folding piece 22 (the portion of the periphery of the folding piece 22 that remains from the main surface 12 even after the folding piece 22 is folded). The fold line 32 extends in the lateral direction of the outlet forming portion 20. The fold line 32 is straight.

[0022] The crease 34 is a crease for folding the folding piece 24. That is, the folding piece 24 is folded along the crease 34. The crease 34 coincides with the rear end of the folding piece 24 (the portion of the periphery of the folding piece 24 that remains attached to the main surface 12 even after the folding piece 24 is folded). The crease 34 extends in the lateral direction of the outlet forming section 20. The crease 34 is straight. The distance between the crease 32 and the crease 34 is, for example, 3 cm or more and 6 cm or less.

[0023] The cut line 42 is located at the boundary between the folding piece 22 and the folding piece 24. The cut line 42 is a perforation. A portion 42a (first portion) of the cut line 42 is wavy and extends laterally of the outlet forming portion 20. The portion 42a is located at the boundary between the holding portion 22a and the holding portion 24a. The portion 42a is formed along a single continuous wavy line. The portion 42a has a shape without corners. The portion 42a is made up of only curves. In this embodiment, the portion 42a describes a sine curve.

[0024] The cut line 44 connects one end of the fold line 32 to one end of the fold line 34. The cut line 44 is a perforation. The cut line 46 connects the other end of the fold line 32 to the other end of the fold line 34. The cut line 46 is a perforation. The side end portion 22c and the side end portion 24c described above coincide with the portion 42b (second portion) of the cut line 42. The portion 42b is a portion other than the portion 42a.

[0025] 6 is a plan view showing a portion of portion 42a of score line 42. The half wavelength d1 of portion 42a is preferably 3 mm or more and 10 mm or less, and more preferably 3 mm or more and 5 mm or less. The half wavelength d1 is half the wavelength of portion 42a. The total amplitude d2 of portion 42a is preferably 3 mm or more and 10 mm or less, and more preferably 3 mm or more and 5 mm or less. The total amplitude d2 is twice the amplitude (half amplitude) of portion 42a.

[0026] The main body 10 is preferably configured to be refillable with items. This configuration can be achieved, for example, by making the main surface 12 or other surfaces openable and closable. The main body 10 is flexible. The main body 10 can be made of, for example, paper such as cardboard. The item storage box 1 is preferably made only of paper.

[0027] FIG. 7 is a perspective view showing the storage box 1 in use. FIG. 8 is a diagram illustrating the structure of an end surface taken along line VIII-VIII in FIG. 7. Items are not shown in FIG. 7. To use the storage box 1, first, cuts are made in the outlet forming portion 20 along the cut lines 42, 44, and 46. Next, the folding pieces 22 and 24 are folded diagonally upward along the creases 32 and 34, respectively. This forms an outlet 50 between the holding portion 22a of the folding piece 22 and the holding portion 24a of the folding piece 24. The item 90 can be removed from the main body 10 by pulling it after it has passed through the outlet 50. Unlike typical tissue storage boxes, the storage box 1 does not have a plastic film at the outlet 50.

[0028] The effects of the item storage box 1 will be described. The item storage box 1 is provided with folding pieces 22 and 24 that are folded diagonally upward along fold lines (fold lines 32 and 34) extending laterally of the outlet forming section 20. The folding pieces 22 and 24 have convex portions 26 and 28, respectively, which are positioned on the same straight line parallel to the vertical direction of the outlet forming section 20 so that the convex portions 26 and 28 are in contact with each other when the folding pieces 22 and 24 are folded. Therefore, even if the folded folding pieces 22 and 24 attempt to return to their original state, the convex portions 26 and 28 can interfere with each other along the way. This prevents the folding pieces 22 and 24 from naturally returning to their original state. This results in an item storage box 1 that makes it easy to smoothly remove items 90 from the main body 10.

[0029] When article 90 is pulled out from outlet 50, a force is applied from article 90 to folding pieces 22 and 24 in a direction that increases the bending angle thereof. In this regard, in article storage box 1, even when the bending angles of folding pieces 22 and 24 increase, protrusions 26 and 28 can be made to interfere with each other. This makes it possible to prevent the bending angles of folding pieces 22 and 24 from becoming too large.

[0030] The bent piece 22 has a holding portion 22a and a restricting portion 22b. By separating the holding portion 22a and the restricting portion 22b in this way, it becomes easier to optimize the shapes, positions, etc. of the holding portion 22a and the restricting portion 22b according to their respective functions. This is advantageous in improving the respective functions of the holding portion 22a and the restricting portion 22b.

[0031] The holding portion 22a and the holding portion 24a are located on the center line L2 that bisects the main surface 12 in the long side direction. This allows the removal opening 50 to be formed in the center of the main surface 12. This also contributes to smooth removal of the article 90 from the main body 10.

[0032] The restricting portions 22b and 24b are provided on both sides of the holding portions 22a and 24a, respectively. In this case, the bending pieces 22 and 24 can be more reliably prevented from returning to their original state, compared to when the restricting portions 22b and 24b are provided only on one side of the holding portions 22a and 24a, respectively.

[0033] The restricting portion 22b protrudes more toward the fold line 34 than the retaining portion 22a. Also, the restricting portion 24b protrudes more toward the fold line 32 than the retaining portion 24a. In this case, the restricting portion 22b and the restricting portion 24b can be adjacent to each other over a wide range in the vertical direction of the outlet forming portion 20. This makes it easier for the protrusions 26 and 28 to interfere with each other.

[0034] The protrusion 26 is formed on the side end 22c of the restricting portion 22b. The protrusion 28 is formed on the side end 24c of the restricting portion 24b. This makes it easier to arrange the protrusions 26 and 28 on the same straight line parallel to the vertical direction of the outlet forming portion 20.

[0035] A plurality of protrusions 26 are formed on one side end 22c. In this case, which of the protrusions 26 interferes with the protrusion 28 depends on the bending angles of the folding pieces 22 and 24. This makes it possible to adjust the bending angles of the folding pieces 22 and 24 in stages.

[0036] A plurality of protrusions 28 are formed on one side end portion 24c. In this case, which of the protrusions 28 interferes with the protrusion 26 depends on the bending angles of the bending pieces 22 and 24. This makes it possible to adjust the bending angles of the bending pieces 22 and 24 in stages.

[0037] The protrusions 26 are formed on both the side end 22c of the restricting portion 22b and the side end 22d of the retaining portion 22a. The protrusions 28 are formed on both the side end 24c of the restricting portion 24b and the side end 24d of the retaining portion 24a. In this case, the folding pieces 22 and 24 can be more reliably prevented from returning to their original states compared to when the protrusions 26 and 28 are formed only on the side end 22c and the side end 24c, respectively.

[0038] When the restricting portions 22b and 24b have shapes that mimic the real thing, the aesthetic appearance of the outlet forming portion 20 and therefore the item storage box 1 can be improved.

[0039] When the actual object is a tree, it is easy to design the restricting portion 22b having a shape with a protrusion 26 on the side end 22c, and it is also easy to design the restricting portion 24b having a shape with a protrusion 28 on the side end 24c. This has the advantage that it is easy to achieve both functionality and design of the restricting portion 22b and the restricting portion 24b.

[0040] The bending piece 22 has a plurality of restricting portions 22b. The bending piece 24 has a plurality of restricting portions 24b. In this case, the bending piece 22 and the bending piece 24 can be more reliably prevented from returning to their original state compared to when the bending piece 22 and the bending piece 24 each have only one restricting portion 22b and one restricting portion 24b.

[0041] The portions 42a of the cut lines 42 are wavy. In this case, unevenness is created at the tip portions of the holding portions 22a and 24a. This can strengthen the holding force of the holding portions 22a and 24a on the article 90.

[0042] Portion 42a of cut line 42 has a shape without any corners, which makes it less likely that article 90 will get caught on the tips of holding portion 22a and holding portion 24a when removed, making it easier to remove article 90 smoothly.

[0043] The portion 42a of the cut line 42 forms a sine curve, which contributes to improving the aesthetic appearance of the outlet forming portion 20 and therefore the item storage box 1.

[0044] Reducing the half wavelength d1 of the portion 42a of the cut line 42 results in finer irregularities at the tip portions of the holding portions 22a and 24a, which is advantageous for strengthening the holding force of the holding portions 22a and 24a on the article 90. From this perspective, the half wavelength d1 is preferably 10 mm or less, and more preferably 5 mm or less. On the other hand, if the half wavelength d1 is too small, the article 90 will easily get caught on the tip portions of the holding portions 22a and 24a. From this perspective, the half wavelength d1 is preferably 3 mm or more.

[0045] Increasing the total amplitude d2 of the portion 42a of the cut line 42 increases the difference in unevenness between the tip portions of the retaining portion 22a and the retaining portion 24a, which is advantageous for strengthening the holding force of the retaining portion 22a and the retaining portion 24a on the item 90. From this perspective, the total amplitude d2 is preferably 3 mm or more. On the other hand, if the total amplitude d2 is too large, the item 90 will penetrate too deeply into the recess, preventing smooth removal of the item 90. From this perspective, the total amplitude d2 is preferably 10 mm or less, and more preferably 5 mm or less.

[0046] If the main body 10 is made of paper, the outer surface of the main body 10 can be used as a canvas for drawing. Also, if a line drawing is printed on the outer surface of the main body 10 in advance, the user can enjoy coloring. That is, a line drawing for coloring may be printed on the outer surface of the main body 10. For this reason, the item storage box 1 is also suitable as a toy for children.

[0047] If the main body 10 is configured to be refilled with the article 90, the main body 10 can be reused by refilling it with new article 90 even after the article 90 has been used up, which is economical. This also leads to a reduction in waste (unnecessary main bodies 10), thereby contributing to a reduction in the environmental burden.

[0048] In the item storage box 1, no plastic film is provided at the outlet 50. This contributes to reducing waste plastic, and therefore the item storage box 1 also has the advantage of being environmentally friendly. (Second embodiment)

[0049] 9 is a plan view showing a second embodiment of an item storage box according to the present invention. The item storage box 2 is an item storage box for storing items and includes a main body 10. In this embodiment, the configurations of the fold lines 32 and 34 are different from those of the first embodiment. In this embodiment, the fold lines 32 are curved and bulge outward from the folding pieces 22. It is preferable that the fold lines 32 describe a circular arc or an elliptical arc.

[0050] FIG. 10 is a plan view showing the crease 32. The curvature of the crease 32 is preferably 1.9% or more and 9.7% or less, and more preferably 1.9% or more and 4.8% or less. Here, the curvature is a numerical value reflecting the magnitude of the curve and is defined as the value obtained by dividing the length d3 by the length d4. The length d3 is equal to the length of the short side of the smallest rectangle R1 that can contain the entire crease 32. The length d3 is, for example, 2 mm or more and 20 mm or less. The length d4 is equal to the length of the long side of the rectangle R1. The short side and long side of the rectangle R1 are parallel to the short side and long side of the main surface 12, respectively. The length d4 is, for example, 120 mm or more and 200 mm or less.

[0051] Returning to FIG. 9 , the fold line 34 has a curved shape that bulges outward from the folding piece 24. The fold line 34 preferably describes a circular or elliptical arc. In this embodiment, the fold line 34 has a shape that is congruent with the fold line 32. The curve rate of the fold line 34 is preferably 1.9% or more and 9.7% or less, and more preferably 1.9% or more and 4.8% or less. The definition of the curve rate of the fold line 34 is the same as the definition of the curve rate of the fold line 32.

[0052] Even if the fold line 32 is curved as in this embodiment, as long as the rectangle R1 has a horizontally elongated shape, the fold line 32 falls under the category of "extending in the horizontal direction of the outlet forming section 20." The same applies to the fold line 34. The other configurations of the main body 10 are as described in the first embodiment.

[0053] FIG. 11 is a perspective view showing the item storage box 2 when in use. FIG. 12 is a view illustrating the structure of the end surface along line AA in FIG. 11. Items are not shown in FIGS. 11 and 12. To use the item storage box 2, first, cuts are made in the outlet forming portion 20 along the cut lines 42, 44, and 46. Next, the folding pieces 22 and 24 are folded diagonally upward along the creases 32 and 34, respectively. This forms an outlet 50 between the holding portion 22a of the folding piece 22 and the holding portion 24a of the folding piece 24. The item can be removed from the main body 10 by pulling the item that has passed through the outlet 50.

[0054] The effects of the item storage box 2 will now be described. In the item storage box 2, the fold lines 32 are curved and bulge outward from the folding pieces 22. In this case, unlike when the item storage box 2 is folded along a straight fold line, a force (return force) acts on the folding pieces 22 that are folded along the fold line 32 to return them to their original state. This makes it possible to prevent the folding angle of the folding pieces 22 from becoming too large. This has the advantage of making it more difficult for dust to enter the main body 10 through the outlet 50.

[0055] Moreover, in this embodiment, the fold line 34 also has a curved shape that bulges outward from the folding piece 24. In this case, a restoring force also acts on the folding piece 24 that is folded along the fold line 34. This makes it possible to prevent the folding angle of the folding piece 24 from becoming too large.

[0056] On the other hand, when a return force acts on the folding pieces 22 and 24, there is a problem that the outlet 50 is likely to become excessively narrow. In this regard, in the item storage box 2, the protrusions 26 and 28 interfere with each other, thereby preventing the outlet 50 from becoming too narrow. In this way, according to this embodiment, the return force acting on the folding pieces 22 and 24 can be regulated by the protrusions 26 and 28. This is advantageous in maintaining the outlet 50 at an appropriate width.

[0057] The mechanism by which the bending angle of the bending piece 22 is restricted by the curved fold line 32 will now be elaborated upon. If the main body 10 were rigid (non-flexible), the bending piece 22 would not be able to be bent along a curve. In contrast, in the item storage box 2, the main body 10 is flexible, so even if the fold line 32 is curved, the bending of the main body 10 makes it possible to bend the bending piece 22 to a certain angle. At this time, a restoring force acts on the bending piece 22 due to the restoring force of the main body 10. This restricts the bending angle of the bending piece 22. The same applies to the mechanism by which the curved fold line 34 restricts the bending angle of the bending piece 24.

[0058] When the fold line 32 forms a circular arc or an elliptical arc, it contributes to improving the aesthetic appearance of the outlet forming section 20 and therefore the item storage box 2. Similarly, when the fold line 34 forms a circular arc or an elliptical arc, it contributes to improving the aesthetic appearance of the outlet forming section 20 and therefore the item storage box 2.

[0059] Increasing the curve of the fold line 32 is advantageous for strengthening the return force acting on the folding piece 22. From this perspective, the curve of the fold line 32 is preferably 1.9% or more. On the other hand, if the curve of the fold line 32 is too large, the return force will be excessively strong, which may make it difficult to remove the article from the removal opening 50. From this perspective, the curve of the fold line 32 is preferably 9.7% or less, and more preferably 4.8% or less.

[0060] Increasing the curve of the fold 34 is advantageous in strengthening the return force acting on the folding piece 24. From this perspective, it is preferable that the curve of the fold 34 be 1.9% or more. On the other hand, if the curve of the fold 34 is too large, the return force will be excessively strong, which may make it difficult to remove the item from the removal opening 50. From this perspective, it is preferable that the curve of the fold 34 be 9.7% or less, and more preferably 4.8% or less. Other effects of the item storage box 2 are the same as those of the item storage box 1.

[0061] In this embodiment, the case where both the crease 32 and the crease 34 are curved has been exemplified. However, as shown in Fig. 13, for example, only one of the crease 32 and the crease 34 may be curved. In this figure, the crease 32 is curved and bulges outward from the folding piece 22, while the crease 34 is straight. (Third embodiment)

[0062] Fig. 14 is a plan view showing a third embodiment of an item storage box according to the present invention. The item storage box 3 is an item storage box for storing items and includes a main body 10. In this embodiment, the configuration of the fold line 34 differs from that of the second embodiment. In this embodiment, the fold line 34 is curved so as to bulge inward from the folding piece 24. It is preferable that the fold line 34 describes a circular arc or an elliptical arc. The curve rate of the fold line 34 is smaller than that of the fold line 32. It is preferable that the curve rate of the fold line 34 is 1 / 4 or more and 3 / 4 or less of the curve rate of the fold line 32. The other configuration of the main body 10 is as described in the second embodiment.

[0063] FIG. 15 is a perspective view showing the item storage box 3 when in use. FIG. 16 is a view for explaining the structure of the end surface along line BB in FIG. 15. Items are not shown in FIGS. 15 and 16. To use the item storage box 3, first, cuts are made in the outlet forming portion 20 along the cut lines 42, 44, and 46. Next, the folding pieces 22 and 24 are folded diagonally upward along the creases 32 and 34, respectively. This forms an outlet 50 between the holding portion 22a of the folding piece 22 and the holding portion 24a of the folding piece 24. The item can be removed from the main body 10 by pulling the item that has passed through the outlet 50.

[0064] The effect of the item storage box 3 will be described. In the item storage box 3, the fold line 32 is curved and bulges outward from the folding piece 22, while the fold line 34 is curved and bulges inward from the folding piece 24. In this case, as shown in FIG. 17 , no cut lines 44, 46 are present on both sides 32b of the fold line 32 (portions that overlap with the fold line 32 when viewed from the long side direction of the main surface 12), whereas cut lines 44, 46 are present on both sides 34b of the fold line 34 (portions that overlap with the fold line 34 when viewed from the long side direction of the main surface 12). For this reason, the folding piece 24, which is bent along the fold line 34, is easier to bend than the folding piece 22, which is bent along the fold line 32. In other words, the bending angle of the folding piece 24 is more likely to be larger than the bending angle of the folding piece 22 (see FIG. 16 ). In this case, the gap (outlet 50) between holding portion 22a and holding portion 24a widens in the height direction of main body 10, so that when an article is taken out, it passes through outlet 50 in a serpentine manner as shown by arrow A1 in Fig. 16. This makes it even more difficult for an article taken out from outlet 50 to fall into main body 10.

[0065] The curve of the crease 34 is smaller than the curve of the crease 32. Making the curve of the crease 34 smaller in this way is also advantageous for making the folding piece 24 easier to fold. This makes it easier to ensure a wide gap between the holding portion 22a and the holding portion 24a in the height direction of the main body 10. From this perspective, it is preferable that the curve of the crease 34 be ¾ or less of the curve of the crease 32. On the other hand, if the curve of the crease 34 is too small, the bending angle of the folding piece 24 may become excessively large. From this perspective, it is preferable that the curve of the crease 34 be ¼ or more of the curve of the crease 32. Other effects of the item storage box 3 are similar to those of the item storage box 2.

[0066] In this embodiment, the curvature of the crease 34 is smaller than that of the crease 32. However, the curvature of the crease 34 may be equal to or larger than that of the crease 32.

[0067] In this embodiment, the folding line 32 has a curved shape that bulges outward from the folding piece 22, while the folding line 34 has a curved shape that bulges inward from the folding piece 24. However, the folding line 32 and the folding line 34 may also have a curved shape that bulges inward from the folding piece 22 and the folding piece 24, respectively. (Fourth embodiment)

[0068] 18 and 19 are perspective views showing a fourth embodiment of an item storage box according to the present invention. Also, Fig. 20 is a side view showing the fourth embodiment of an item storage box according to the present invention. The item storage box 4 is an item storage box for storing items, and includes a main body 110.

[0069] The main body 110 is box-shaped and includes a bottom surface 120, a side surface 132 (first side surface), a side surface 134 (second side surface), a side surface 136 (third side surface), a side surface 138 (fourth side surface), and a top surface 140. The main body 110 is rectangular parallelepiped-shaped. FIGS. 18 and 19 are perspective views seen from the top surface 140 side and the bottom surface 120 side, respectively. FIG. 20 is a side view seen from the side surface 134 side. The side surface 132 and the side surface 134 face each other. The side surface 136 and the side surface 138 also face each other. The widths of the side surface 132 and the side surface 134 are greater than the widths of the side surface 136 and the side surface 138. The top surface 140 is equal to the main surface 12, and the outlet forming portion 20 is provided on the top surface 140. The configuration of the outlet forming section 20 is as described in the first, second or third embodiment. However, in this embodiment, detailed illustration of the outlet forming section 20 is omitted. The main body 110 is configured so that it can be deformed into a bottom-up state. The main body 110 can be made of, for example, cardboard or other paper.

[0070] The main body 110 has a cut line 150 (first cut line), a cut line 160 (second cut line), a tongue portion 170, and a slit portion 180. The cut line 150 is formed from the bottom surface portion 120 to the side surface portion 132. The cut line 150 is formed along a single continuous line. The cut line 150 is a perforation. The cut line 150 consists of a bottom surface cut portion 151 (first bottom surface cut portion), a bottom surface cut portion 152 (second bottom surface cut portion), a bottom surface cut portion 153 (third bottom surface cut portion), a side surface cut portion 154 (first side surface cut portion), and a side surface cut portion 155 (second side surface cut portion). The bottom surface cut portions 151 to 153 are formed on the bottom surface portion 120. Side cutout portion 154 and side cutout portion 155 are formed on side portion 132. Bottom cutout portion 151 and bottom cutout portion 152, and side cutout portion 154 and side cutout portion 155 are all aligned in a straight line. In this embodiment, bottom cutout portion 153 is also aligned in a straight line.

[0071] Bottom cutout portion 151 and bottom cutout portion 152 extend from side surface portion 132 toward side surface portion 134. Bottom cutout portion 151 and bottom cutout portion 152 extend perpendicular to side surface portion 132. Bottom cutout portion 153 connects bottom cutout portion 151 and bottom cutout portion 152. Specifically, bottom cutout portion 153 connects one end of bottom cutout portion 151 to one end of bottom cutout portion 152. One end of bottom cutout portion 151 and one end of bottom cutout portion 152 are located in the middle of bottom surface portion 120. Here, the middle of bottom surface portion 120 refers to the part of bottom surface portion 120 other than the edges (boundaries with each of side surface portions 132, 134, 136, and 138). The bottom cutout portion 153 extends parallel to the side surface portion 132 .

[0072] Side cutout portion 154 and side cutout portion 155 are continuous with bottom cutout portion 151 and bottom cutout portion 152, respectively. That is, one end of side cutout portion 154 and one end of side cutout portion 155 are connected to the other end of bottom cutout portion 151 and the other end of bottom cutout portion 152, respectively. Side cutout portion 154 and side cutout portion 155 extend in the height direction of main body 110 (the up-and-down direction in Figures 18 and 19). The other ends of side cutout portion 154 and side cutout portion 155 are located in the middle of side portion 132. Here, the middle portion of side portion 132 refers to the part of side portion 132 other than the edge (the boundary with bottom portion 120, the boundaries with each side portion 136, 138, and the boundary with top portion 140).

[0073] The cut line 160 is formed on the side surface portion 134. The cut line 160 is formed along a single continuous line. The cut line 160 is a perforation. The cut line 160 includes a vertical cut portion 161 (first vertical cut portion), a vertical cut portion 162 (second vertical cut portion), and a horizontal cut portion 163. The cut line 160 consists only of the vertical cut portion 161, the vertical cut portion 162, and the horizontal cut portion 163. The vertical cut portions 161 and 162, and the horizontal cut portion 163 are all linear. The vertical cut portions 161 and 162 extend in the height direction of the main body 110. The horizontal cut portion 163 connects one end of the vertical cut portion 161 to one end of the vertical cut portion 162. One end of vertical cut portion 161 and one end of vertical cut portion 162 are located in the middle of side surface portion 134. The other end of vertical cut portion 161 and the other end of vertical cut portion 162 are also located in the middle of side surface portion 134. Here, the middle of side surface portion 134 refers to the part of side surface portion 134 other than the edge (the boundary with bottom surface portion 120, the boundaries with each of side surface portions 136 and 138, and the boundary with top surface portion 140). Horizontal cut portion 163 extends parallel to bottom surface portion 120.

[0074] 21, 22, and 23 are respectively a perspective view, a plan view, and a side view showing the main body 110 after deformation. Fig. 21 is a perspective view seen from the bottom surface portion 120 side. Fig. 23 is a side view seen from the side surface portion 132 side. Fig. 24 is a diagram for explaining the structure of the end surface along line CC in Fig. 22.

[0075] The tongue portion 170 is a portion that becomes the tongue portion 172 connected to the middle portion of the side portion 132 when a cut is made in the main body 110 (the bottom surface portion 120 and the side surface portion 132) along the cut line 150. The tongue portion 172 is formed of a single plate that is made up of a part of the bottom surface portion 120 and a part of the side surface portion 132. In this embodiment, the shape of the tongue portion 172 is rectangular. The side surface portion 132 is provided with a fold line 133 (third fold line) for folding the tongue portion 172 toward the side surface portion 134. The fold line 133 is provided in a position that overlaps with a slit portion 180, which will be described later, in a side view. The fold line 133 connects the other end of the side surface cut portion 154 and the other end of the side surface cut portion 155. The fold line 133 is parallel to the bottom surface portion 120. It is preferable that fold lines 133 are formed in advance so that tongue piece 172 can be easily folded along fold line 133. However, fold line 133 may consist only of a line printed on side surface portion 132 to inform the user of the position of the fold.

[0076] The length of the tongue 172 is preferably at least 1.1 times, and more preferably at least 1.2 times, the distance d10 (see FIG. 19) from the side surface portion 132 to the side surface portion 134. The length of the tongue 172 is preferably at least 1 cm longer than the distance d10, and more preferably at least 2 cm longer. Here, the length of the tongue 172 is the maximum dimension of the tongue 172 in a direction perpendicular to the side surface portion 132 when the tongue 172 is spread out on a plane parallel to the bottom surface portion 120. In this embodiment, the length of the tongue 172 is equal to the sum of the length d11 of each bottom surface cutout 151, 152 and the length d12 of each side surface cutout 154, 155. The width w11 of the tongue 172 is preferably at least ½, and more preferably at least ¾, of the width w10 of the side surface portion 132. Here, the width w11 is the maximum dimension of the tongue piece 172 in the direction perpendicular to the side surface portion 136 and the side surface portion 138.

[0077] The slit portion 180 is a portion that is located in the middle of the side surface portion 134 when a cut is made in the main body 110 (side surface portion 134) along the cut line 160, and that serves as a slit 182 into which the tongue 172 can be inserted. The slit 182 is a horizontally elongated opening that extends parallel to the bottom surface portion 120. The tongue 172 is configured to be parallel to the bottom surface portion 120 when inserted into the slit 182. The side surface portion 134 is provided with a fold line 135 for folding the portion 180a surrounded by the cut line 160 (the vertical cut portion 161, the vertical cut portion 162, and the horizontal cut portion 163) outward from the main body 110. The fold line 135 connects the other end of the vertical cut portion 161 to the other end of the vertical cut portion 162. The fold line 135 is parallel to the bottom surface portion 120. It is preferable that fold lines 135 have creases formed in advance to make it easier to fold portion 180a along fold line 135. However, fold line 135 may consist only of a line printed on side portion 134 to inform the user of the fold position.

[0078] In the height direction of main body 110, distance h11 (see FIG. 20) from bottom surface portion 120 to slit portion 180 is preferably equal to or greater than ½ of height h10 of main body 110. Similarly, in the height direction of main body 110, distance from bottom surface portion 120 to fold line 133 (equal to length d12 of each side cut portion 154, 155) is also preferably equal to or greater than ½ of height h10.

[0079] Next, an example of a method for deforming the main body 110 will be described. First, a cut is made in the main body 110 along the cut line 160. Then, the portion 180a surrounded by the cut line 160 is folded outward along the fold line 135, thereby turning the slit portion 180 into a slit 182. Next, a cut is made in the main body 110 along the cut line 150, turning the tongue portion 170 into a tongue 172. Next, the tongue 172 is inserted into the slit 182 while being folded along the fold line 133 toward the side portion 134. This allows the main body 110 to be deformed so that the tongue 172 is inserted into the slit 182 (see FIGS. 21 to 24). In the deformed main body 110, an item 190 is placed on the tongue 172, as shown in FIG. 24. By raising the bottom of the item storage box 4 (main body 110) and bringing the items 190 closer to the top surface 140 in this way, the items 190 can be smoothly removed from the removal opening even when the remaining amount of items 190 is low. In this case, the distance from the tongue 172 to the top surface 140 is preferably 3 cm or more and 6 cm or less. Note that the items 190 are not shown in Figures 22 and 23.

[0080] Letters or a design are printed on the protruding portion 172a of the tongue 172 (see FIG. 22). The protruding portion 172a is a portion that protrudes from the slit 182 to the outside of the main body 110. The letters or design are printed on the upper surface of the protruding portion 172a (the surface on the top surface portion 140 side). In FIG. 22, as an example, the character string "ABC" is printed on the upper surface of the protruding portion 172a. This upper surface corresponds to a portion of the inner surface of the bottom surface portion 120 of the main body 110 before deformation. In other words, by printing letters or a design on this portion in advance, it is possible to realize the protruding portion 172a with letters or a design printed on its upper surface. The protruding portion 172a may be printed with company promotional text, advertising, or other promotional slogans. The content of the company promotional text may, for example, introduce the company's efforts to address environmental issues.

[0081] Furthermore, letters or designs are printed on the specified portion 134a on the inner surface of the side surface portion 134. The specified portion 134a is a portion that overlaps the tongue portion 170 (the portion of the tongue portion 170 that is present on the side surface portion 132) in a side view. In FIG. 23, for example, the character string "XYZ" is printed on the specified portion 134a. However, the character string is not shown in FIG. 21. An advertising slogan may be printed on the specified portion 134a.

[0082] A scented portion 112 may be provided in the lower portion 110a of the inner surface of the main body 110, as shown in FIG. 25, for example. The lower portion 110a is the portion that exists below the tongue 172 when inserted into the slit 182. The lower portion 110a comprises a portion of the inner surface of the bottom portion 120 and a portion of the inner surfaces of each of the side portions 132, 134, 136, and 138. In FIG. 25, the scented portion 112 is provided in a specific portion 134a, which is a portion of the lower portion 110a. A fragrance is attached to the scented portion 112. The scented portion 112 can be realized, for example, by printing a fragrance on the lower portion 110a. A peelable sticker 114 is attached to the scented portion 112. Here, "peelable" means that the sticker 114 can be easily peeled off from the scented portion 112 without damaging the lower portion 110a or the scented portion 112. The seal 114 prevents the fragrance in the scented portion 112 from escaping.

[0083] The effects of the item storage box 4 will be described. In the item storage box 4, a tongue portion 170 and a slit portion 180 are provided on the main body 110. The tongue portion 170 provides a tongue 172 connected to the middle portion of the side surface portion 132. The slit portion 180 provides a slit 182 located in the middle portion of the side surface portion 134 and into which the tongue 172 can be inserted. By inserting the tongue 172 into the slit 182, the tongue 172 can be suspended from the middle portion of the side surface portion 132 to the middle portion of the side surface portion 134. Therefore, when the remaining amount of items is low, the tongue 172 can be inserted into the slit 182 so that an item can be placed on the tongue 172, thereby raising the bottom of the item storage box 4 while the tongue 172 makes surface contact with the item. Therefore, an item storage box 4 that can stably support items when the bottom is raised is realized without providing a bottom-raising member separate from the main body 110.

[0084] Incidentally, storing as many items as possible in an item storage box is advantageous in reducing the price per item. However, increasing the number of items that can be stored in a single item storage box requires increasing the height of the main body. Typically, increasing the height of the main body makes it difficult to remove items when there are only a few items left. In this regard, the item storage box 4, which has a raised bottom, makes it easy to remove items even when there are only a few items left, thereby eliminating the problem of increasing the height of the main body 110. Furthermore, increasing the height of the main body 110 makes it possible to secure a large space for printing letters or designs. Furthermore, since used main bodies 110 become waste, storing a large number of items in a single main body 110 also reduces waste.

[0085] Tongue piece 172 is connected to side surface portion 132 without being separated from main body 110. In this case, a part of tongue piece 172 is fixed to side surface portion 132, which makes it difficult for tongue piece 172 to accidentally come out of slit 182.

[0086] The tongue piece 172 is configured so as to be parallel to the bottom surface portion 120 when inserted into the slit 182. This also contributes to stable support of the articles in the article storage box 4 after the bottom has been raised.

[0087] Increasing the distance h11 from the bottom surface portion 120 to the slit portion 180 in the height direction of the main body 110 is advantageous in enhancing the bottom-raising effect of the item storage box 4. From this perspective, it is preferable that the distance h11 be equal to or greater than 1 / 2 of the height h10 of the main body 110. On the other hand, if the distance h11 is too large, the amount of items that can be stored in the item storage box 4 after deformation will be extremely small. From this perspective, it is preferable that the distance h11 be equal to or less than 4 / 5 of the height h10.

[0088] The side surface portion 132 is provided with a folding line 133. This makes it easier to fold the tongue piece 172 neatly at a predetermined position.

[0089] The fold line 133 is provided at a position that overlaps the slit portion 180 in a side view. This makes it easier to position the tongue piece 172 inserted into the slit 182 parallel to the bottom surface portion 120.

[0090] Increasing the length of the tongue 172 is advantageous in preventing the tongue 172 from accidentally slipping out of the slit 182. From this perspective, the length of the tongue 172 is preferably 1.1 times or more, and more preferably 1.2 times or more, the distance d10 from the side surface portion 132 to the side surface portion 134. From a similar perspective, the length of the tongue 172 is preferably 1 cm or more longer than the distance d10, and more preferably 2 cm or more longer. On the other hand, if the length of the tongue 172 is too long, it may be difficult to secure the tongue portion 170 in the main body 110 before deformation. From this perspective, the length of the tongue 172 is preferably 1.5 times or less the distance d10. From a similar perspective, the difference between the length of the tongue 172 and the distance d10 is preferably 5 cm or less.

[0091] The cut line 150 is made up of bottom cut portions 151 to 153, and side cut portions 154 and 155. This makes it possible to realize the cut line 150 for forming the tongue piece 172 with a simple configuration.

[0092] The bottom cutouts 151 and 152, and the side cutouts 154 and 155 are all aligned in a straight line, which makes it easy to make cuts along the bottom cutouts 151 and 152 and the side cutouts 154 and 155.

[0093] The bottom cutout portions 151 and 152 extend perpendicular to the side surface portion 132. In this case, the length of each of the bottom cutout portions 151 and 152 can be minimized. This also makes it easier to make cuts along each of the bottom cutout portions 151 and 152.

[0094] The side cutout portions 154 and 155 extend in the height direction of the main body 110. In this case, the length of each of the side cutout portions 154, 155 can be minimized. This also makes it easier to make cuts along each of the side cutout portions 154, 155.

[0095] The bottom cutout portion 153 is formed in a straight line, which makes it easy to make cuts along the bottom cutout portion 153.

[0096] The bottom cutout portion 153 extends parallel to the side surface portion 132. This allows the dimensions of the tongue piece 172 in the direction perpendicular to the side surface portion 132 to be constant.

[0097] Increasing the width w11 of the tongue 172 allows the tongue 172 to come into contact with a wider area of ​​the item, which is advantageous for stably supporting the item in the item storage box 4 after the bottom has been raised. Furthermore, increasing the width w11 makes it less likely that debris from the item (for example, paper dust from tissue paper) will fall outside the main body 110, and also reduces the item's exposure to the outside air, making it more hygienic. From this perspective, the width w11 is preferably at least 1 / 2 of the width w10 of the side portion 132, and more preferably at least 3 / 4 of the width w10. On the other hand, if the width w11 is too large, it may be difficult to secure the tongue portion 170 in the main body 110 before deformation. From this perspective, the width w11 is preferably no more than 9 / 10 of the width w10.

[0098] The width of the side surface portion 132 and the side surface portion 134 is greater than the width of the side surface portion 136 and the side surface portion 138. By providing the tongue portion 170 and the slit portion 180 in the pair of side surface portions (side surface portion 132 and side surface portion 134) that are relatively wider in this way, it becomes easier to increase the width w11 of the tongue portion 172 while ensuring a sufficient length of the tongue portion 172.

[0099] The cut line 160 includes a vertical cut portion 161, a vertical cut portion 162, and a horizontal cut portion 163. This allows the cut line 160 for forming the slit 182 to be realized with a simple configuration.

[0100] The vertical cut portions 161 and 162 and the horizontal cut portion 163 are all linear, which makes it easy to make cuts along the vertical cut portions 161 and 162 and the horizontal cut portion 163.

[0101] The cut line 160 consists only of vertical cut portions 161 and 162, and horizontal cut portion 163. In this case, the portion 180a surrounded by the cut line 160 is not cut off from the main body 110, so that the portion 180a can be brought into contact with the protruding portion 172a of the tongue piece 172. This makes it even more unlikely that the tongue piece 172 will accidentally come out of the slit 182.

[0102] Letters or designs are printed on the protruding portion 172a of the tongue piece 172. By printing letters or designs on the protruding portion 172a, which becomes visible from the outside of the transformed main body 110, the aesthetic appearance of the transformed main body 110 can be improved.

[0103] The letters or designs are printed on the top surface of the protruding portion 172a. By printing on the top surface, which is easily visible, the letters or designs can be made to stand out.

[0104] If an advertising slogan is printed on the outlet portion 172a, the outlet portion 172a can be used as advertising space. If advertisers are recruited, it is possible to earn advertising revenue. If this revenue is used to cover the manufacturing costs of the item storage box 4, the product price of the item storage box 4 can be kept low.

[0105] Letters or designs are printed on specific portions 134a on the inner surfaces of side portions 134. By printing letters or designs on specific portions 134a that are visible from the outside of main body 110 after deformation, the aesthetic appearance of main body 110 after deformation can be improved.

[0106] If an advertising slogan is printed on the specified portion 134a, the specified portion 134a can be used as advertising space. If advertisers are solicited, it is possible to earn advertising revenue. If this revenue is used to cover the manufacturing costs of the item storage box 4, the product price of the item storage box 4 can be reduced.

[0107] When fragrance section 112 is provided in lower portion 110a of the inner surface of main body 110, it is possible to disperse a fragrance around main body 110 after it has been deformed. That is, by peeling off seal 114 after deforming main body 110, the fragrance in fragrance section 112 can be dispersed around main body 110. Furthermore, because seal 114 is affixed to fragrance section 112, the user can select whether or not to disperse a fragrance around main body 110 by whether or not to peel off seal 114.

[0108] When the scented section 112 is provided in a specific section 134a on the inner surface of the side section 134, the specific section 134a is an easily accessible part of the lower section 110a, making it easy to peel off the seal 114. Other effects of the item storage box 4 are the same as those of the item storage boxes 1 to 3.

[0109] In this embodiment, the tongue piece 172 has a rectangular shape. However, the tongue piece 172 may have a tapered shape, for example, as shown in Fig. 26. In this case, the tongue piece 172 can be easily inserted into the slit 182.

[0110] In this embodiment, the horizontal cut portion 163 of the cut line 160 is shown as a straight line. However, the horizontal cut portion 163 may be wavy, as shown in Fig. 27. In this case, the tongue piece 172 inserted into the slit 182 can be sandwiched between the convex portions from above and below, making it even more unlikely that the tongue piece 172 will accidentally come out of the slit 182.

[0111] In this embodiment, the main body 110 may have a plurality of slit portions 180, as shown in FIG. 28, for example. The plurality of slit portions 180 are provided at different positions in the height direction of the main body 110. In this example, a plurality of fold lines 133 are provided in the side surface portion 132, as shown in FIG. 29. The plurality of fold lines 133 are provided at different positions in the height direction of the main body 110. Each fold line 133 is provided at a position overlapping with a corresponding slit portion 180 in a side view. That is, the fold line 133 provided on the upper side of the side surface portion 132 overlaps with the slit portion 180 provided on the upper side of the side surface portion 134, and the fold line 133 provided on the lower side of the side surface portion 132 overlaps with the slit portion 180 provided on the lower side of the side surface portion 134. It is preferable that when inserting tongue piece 172 into upper slit 182, tongue piece 172 is folded along upper fold line 133, and when inserting tongue piece 172 into lower slit 182, tongue piece 172 is folded along lower fold line 133. Side cutout portion 154 and side cutout portion 155 pass through the end of lower fold line 133 and extend to the end of upper fold line 133.

[0112] When multiple slits 180 are provided in this manner, the height of tongue 172 (the distance from bottom surface 120) can be adjusted by inserting tongue 172 into any of the slits 182. This makes it possible to select the degree of bottom raising depending on the amount of articles remaining. Furthermore, by providing multiple fold lines 133, tongue 172 can be more easily positioned parallel to bottom surface 120 regardless of which of the slits 182 tongue 172 is inserted into.

[0113] In this embodiment, the cut line 160 is located below the fold line 135. However, the cut line 160 may be located above the fold line 135, as shown in FIG.

[0114] In the present embodiment, the case where the cut line 160 is formed along a single non-circular line has been exemplified. However, the cut line 160 may be formed along a single circular line, as shown in Fig. 31, for example. In that case, the portion 180a surrounded by the cut line 160 is cut off from the side surface portion 134, and a slit 182 having the same shape and size as the portion 180a is obtained.

[0115] In this embodiment, the cut line 160 is formed along a plurality of line segments. However, the cut line 160 may be formed along a single line segment, as shown in Fig. 32. In this figure, the cut line 160 is entirely straight.

[0116] In this embodiment, the cut lines 150 and 160 are perforations. That is, the cut lines 150 and 160 are configured so that the cuts are made along the cut lines 150 and 160 only when force is applied to both sides of the cut lines 150 and 160. However, the cut lines 150 and 160 may be made in advance. (Fifth embodiment)

[0117] Figures 33 and 34 are perspective views showing a fifth embodiment of an item storage box according to the present invention. Figure 35 is a bottom view showing the fifth embodiment of an item storage box according to the present invention. Figures 36 and 37 are side views showing the fifth embodiment of an item storage box according to the present invention. The item storage box 5 is an item storage box for storing items and includes a main body 210.

[0118] The main body 210 is box-shaped and includes a bottom surface 220, a side surface 232 (first side surface), a side surface 234 (second side surface), a side surface 236 (third side surface), a side surface 238 (fourth side surface), and a top surface 240.

FIGS. 36 and 37 are side views seen from the side surface 232 side and the side surface 234 side, respectively. The side surface 232 and the side surface 234 face each other. The side surface 236 and the side surface 238 also face each other. The widths of the side surface 232 and the side surface 234 are greater than the widths of the side surface 236 and the side surface 238. The top surface 240 is equal to the main surface 12, and is provided with an outlet forming portion 20. The configuration of the outlet forming portion 20 is as described in the first, second, or third embodiment. However, in this embodiment, detailed illustration of the outlet forming portion 20 is omitted. The main body 210 is configured so that it can be deformed into a bottom-up state. The main body 210 can be made of, for example, paper such as cardboard.

[0119] The main body 210 has a cut line 250 (first cut line), a cut line 262 (second cut line), a cut line 264 (third cut line), a cut piece portion 270, a slit portion 282 (first slit portion), and a slit portion 284 (second slit portion). The cut line 250 is formed in at least one of the bottom surface portion 220, the side surface portion 232, and the side surface portion 234. In this embodiment, the cut line 250 is formed only in the bottom surface portion 220. As shown in FIG. 35 , the cut line 250 is formed along a single circular line. The cut line 250 is a perforation. The cut line 250 consists of a cut portion 251 (first cut portion), a cut portion 252 (second cut portion), a cut portion 253 (third cut portion), and a cut portion 254 (fourth cut portion). The cutout portion 251 and the cutout portion 252 are aligned in a straight line. In this embodiment, the cutout portion 253 and the cutout portion 254 are also aligned in a straight line.

[0120] Cutout portion 251 and cutout portion 252 extend parallel to side surface portion 232. Cutout portion 253 connects one end of cutout portion 251 to one end of cutout portion 252. One end of cutout portion 251 and one end of cutout portion 252 are located in the middle of bottom surface portion 220. Here, the middle of bottom surface portion 220 refers to the part of bottom surface portion 220 other than the edges (boundaries with each of side surface portions 232, 234, 236, and 238). Cutout portion 254 connects the other end of cutout portion 251 to the other end of cutout portion 252. The other end of cutout portion 251 and the other end of cutout portion 252 are located in the middle of bottom surface portion 220. Cutout portion 253 and cutout portion 254 extend perpendicular to side surface portion 232.

[0121] The cut line 262 is formed on the side surface portion 232. As shown in FIG. 36 , the cut line 262 is formed along a single continuous line. The cut line 262 is a perforation. The cut line 262 includes a vertical cut portion 262a (first vertical cut portion), a vertical cut portion 262b (second vertical cut portion), and a horizontal cut portion 262c. The cut line 262 consists only of the vertical cut portion 262a, the vertical cut portion 262b, and the horizontal cut portion 262c. The vertical cut portions 262a and 262b, and the horizontal cut portion 262c are all linear. The vertical cut portions 262a and 262b extend in the height direction of the main body 210. The horizontal cut portion 262c connects one end of the vertical cut portion 262a and one end of the vertical cut portion 262b. One end of the vertical cut portion 262a and one end of the vertical cut portion 262b are located in the middle of the side surface portion 232. The other end of the vertical cut portion 262a and the other end of the vertical cut portion 262b are also located in the middle of the side surface portion 232. Here, the middle of the side surface portion 232 refers to the part of the side surface portion 232 other than the edge (the boundary with the bottom surface portion 220, the boundaries with the side surface portions 236 and 238, and the boundary with the top surface portion 240). The horizontal cut portion 262c extends parallel to the bottom surface portion 220.

[0122] The cut line 264 is formed on the side surface portion 234. As shown in FIG. 37, the cut line 264 is formed along a single continuous line. The cut line 264 is a perforation. The cut line 264 includes a vertical cut portion 264a (first vertical cut portion), a vertical cut portion 264b (second vertical cut portion), and a horizontal cut portion 264c. The cut line 264 consists only of the vertical cut portion 264a, the vertical cut portion 264b, and the horizontal cut portion 264c. The vertical cut portion 264a, the vertical cut portion 264b, and the horizontal cut portion 264c are all linear. The vertical cut portion 264a and the vertical cut portion 264b extend in the height direction of the main body 210. The horizontal cut portion 264c connects one end of the vertical cut portion 264a and one end of the vertical cut portion 264b. One end of the vertical cut portion 264a and one end of the vertical cut portion 264b are located in the middle of the side surface portion 234. The other end of the vertical cut portion 264a and the other end of the vertical cut portion 264b are also located in the middle of the side surface portion 234. Here, the middle of the side surface portion 234 refers to the part of the side surface portion 234 other than the edge (the boundary with the bottom surface portion 220, the boundaries with the side surfaces 236 and 238, and the boundary with the top surface portion 240). The horizontal cut portion 264c extends parallel to the bottom surface portion 220.

[0123] Figures 38 and 39 are perspective views showing main body 210 after deformation. Figures 38 and 39 are perspective views seen from side surface portion 232 and side surface portion 234, respectively. Figures 40 and 41 are plan and bottom views showing main body 210 after deformation, respectively. Also, Figure 42 is a view for explaining the structure of the end face taken along line DD in Figure 40.

[0124] The cut piece portion 270 is a portion that becomes the cut piece 272 when cut from the main body 210 (bottom surface portion 220) along the cut line 250. The cut piece 272 is made of a single plate that is a part of the bottom surface portion 220. In this embodiment, the shape of the cut piece 272 is rectangular.

[0125] The length d21 of the segment 272 (see FIG. 35) is preferably 1.2 times or more, and more preferably 1.4 times or more, the distance d20 from the side surface portion 232 to the side surface portion 234. Furthermore, the length d21 is preferably 2 cm or more longer than the distance d20, and more preferably 4 cm or more longer. The length d21 is, for example, 14 cm or more and 20 cm or less. Here, the length d21 is the maximum dimension of the segment 272 in the insertion direction of the segment 272 into the slit portions 282 and 284 described below. In this embodiment, the length d21 is equal to the length of each of the cut portions 251 and 252. The width w21 of the segment 272 is preferably ¼ or more, and more preferably ½ or more, of the width w20 of the side surface portion 232. The width w21 is, for example, 6 cm or more and 10 cm or less. Here, the width w21 is the maximum dimension of the segment 272 in the direction perpendicular to the insertion direction. In this embodiment, the width w21 is equal to the length of each of the cutout portions 253 and 254.

[0126] The slit portion 282 is a portion that becomes a slit 283 (first slit) that is located in the middle of the side surface portion 232 and into which the piece 272 can be inserted when a cut is made in the main body 210 (side surface portion 232) along the cut line 262. The slit 283 is a horizontally long opening that extends parallel to the bottom surface portion 220. The side surface portion 232 is provided with a fold line 233 for folding the portion 282a surrounded by the cut line 262 (the vertical cut portion 262a, the vertical cut portion 262b, and the horizontal cut portion 262c) outward from the main body 210. The fold line 233 connects the other end of the vertical cut portion 262a to the other end of the vertical cut portion 262b. The fold line 233 is parallel to the bottom surface portion 220. It is preferable that a crease be formed in advance on the fold line 233 to make it easier to fold the portion 282a along the fold line 233. However, the fold line 233 may consist of only a line printed on the side surface portion 232 to inform the user of the position of the fold.

[0127] The slit portion 284 is a portion that is located in the middle of the side surface portion 234 when a cut is made in the main body 210 (side surface portion 234) along the cut line 264, and that serves as a slit 285 (second slit) into which the segment 272 can be inserted. The slit 285 is a horizontally elongated opening that extends parallel to the bottom surface portion 220. The segment 272 is configured to be parallel to the bottom surface portion 220 when inserted into the slit 283 and the slit 285. The side surface portion 234 is provided with a fold line 235 for folding the portion 284a surrounded by the cut line 264 (the vertical cut portion 264a, the vertical cut portion 264b, and the horizontal cut portion 264c) outward from the main body 210. The fold line 235 connects the other end of the vertical cut portion 264a to the other end of the vertical cut portion 264b. The fold line 235 is parallel to the bottom surface portion 220. It is preferable that fold lines 235 have creases formed in advance to make it easier to fold portion 284a along fold line 235. However, fold line 235 may consist of only a line printed on side portion 234 to inform the user of the fold position.

[0128] In the height direction of main body 210, distance h21 from bottom surface portion 220 to slit portion 282 (see FIG. 36) is preferably equal to or greater than half of height h20 of main body 210. Similarly, in the height direction of main body 210, distance h22 from bottom surface portion 220 to slit portion 284 (see FIG. 37) is also preferably equal to or greater than half of height h20. Slit portion 282 and slit portion 284 are formed at positions that overlap each other in side view.

[0129] Next, an example of a method for deforming the main body 210 will be described. First, a cut is made in the main body 210 along the cut line 262. Then, the portion 282a surrounded by the cut line 262 is folded outward along the fold line 233, thereby changing the slit portion 282 into a slit 283. Also, a cut is made in the main body 210 along the cut line 264. Then, the portion 284a surrounded by the cut line 264 is folded outward along the fold line 235, thereby changing the slit portion 284 into a slit 285. Next, a cut is made in the main body 210 along the cut line 250 to separate the cut piece portion 270 from the main body 210, thereby changing the cut piece portion 270 into a cut piece 272. Next, the cut piece 272 is inserted into the slit 283 and the slit 285 so that its short side is parallel to the side surface portion 232. At this time, it is preferable to insert the piece 272 with the main body 210 turned upside down so that the article is placed between the upper surface portion 240 and the piece 272. This allows the main body 210 to be deformed so that the piece 272 is inserted into the slits 283 and 285 (see FIGS. 38 to 42).

[0130] In the deformed main body 210, the article 290 is placed on the cut piece 272, as shown in Fig. 42. By raising the bottom of the article storage box 5 (main body 210) in this way and bringing the article 290 closer to the upper surface portion 240, the article 290 can be smoothly removed from the removal opening even when the remaining amount of the article 290 is low. In this case, the distance from the cut piece 272 to the upper surface portion 240 is preferably 3 cm or more and 6 cm or less. Note that the illustration of the article 290 is omitted in Figs. 38 to 41.

[0131] Letters or a design are printed on the protruding portion 272a of the piece 272 (see FIG. 40). The protruding portion 272a is a portion that protrudes from each slit 283, 285 to the outside of the main body 210. The letters or design are printed on the upper surface of the protruding portion 272a (the surface on the top surface portion 240 side). In FIG. 40, as an example, the character string "ABC" is printed on the upper surface of the protruding portion 272a. This upper surface corresponds to a portion of the inner surface of the bottom surface portion 220 of the main body 210 before deformation. In other words, by printing letters or a design on this portion in advance, it is possible to realize the protruding portion 272a with letters or a design printed on its upper surface. The protruding portion 272a may be printed with company promotional text, advertising, or other promotional slogans. The content of the company promotional text may, for example, introduce the company's efforts to address environmental issues.

[0132] Furthermore, letters or designs are printed on lower portion 210a of the inner surface of main body 210. Lower portion 210a is the portion that is present below piece 272 when inserted into slits 283 and 285. Lower portion 210a consists of a part of the inner surface of bottom portion 220 and a part of the inner surface of each of side portions 232, 234, 236, and 238. Advertising slogans may be printed on lower portion 210a.

[0133] The lower portion 210a may be provided with a scented portion 212, as shown in FIG. 43, for example. In the figure, the scented portion 212 is provided on the inner surface of the side portion 234. A fragrance is attached to the scented portion 212. The scented portion 212 can be realized, for example, by printing the fragrance on the lower portion 210a. A peelable sticker 214 is attached to the scented portion 212. Here, "peelable" means that the sticker 214 can be easily peeled off from the scented portion 212 without damaging the lower portion 210a and the scented portion 212. The sticker 214 prevents the fragrance in the scented portion 212 from dissipating.

[0134] The effects of the item storage box 5 will be described. In the item storage box 5, the section 270 and the slits 282 and 284 are provided on the main body 210. The section 270 provides the section 272 that is cut off from the main body 210. The slits 282 and 284 provide the slits 283 and 285 that are located in the middle of the side surface 232 and the side surface 234, respectively, and into which the section 272 can be inserted. By inserting the section 272 into the slits 283 and 285, the section 272 can be stretched from the middle of the side surface 232 to the middle of the side surface 234. Therefore, when the remaining amount of items is low, the section 272 can be inserted into the slits 283 and 285 so that the item is placed on the section 272, thereby raising the bottom of the item storage box 5 while the section 272 comes into surface contact with the item. Therefore, an article storage box 5 is realized that can stably support articles when the bottom is raised, without providing a bottom-raising member separate from the main body 210.

[0135] Furthermore, after the piece 272 is cut off from the main body 210, an opening remains where the piece 270 was. In the item storage box 5, it is also possible to replenish items into the main body 210 through this opening.

[0136] Incidentally, storing as many items as possible in an item storage box is advantageous in reducing the price per item. However, increasing the number of items that can be stored in a single item storage box requires increasing the height of the main body. Typically, increasing the height of the main body makes it difficult to remove items when the remaining amount is low. In this regard, the item storage box 5, which has a raised bottom, makes it easy to remove items even when the remaining amount is low, thereby solving the above problem caused by increasing the height of the main body 210. Furthermore, increasing the height of the main body 210 makes it possible to secure a large space for printing letters or designs. Furthermore, since used main bodies 210 become waste, storing a large number of items in a single main body 210 also reduces waste.

[0137] The segment 272 is in a state where it is separated from the main body 210. In this case, the segment 272 can be freely displaced with respect to the main body 210, and therefore, the segment 272 can be easily inserted into the slits 283 and 285.

[0138] The segment 272 is configured so as to be parallel to the bottom surface portion 220 when inserted into the slits 283 and 285. This also contributes to stable support of the items in the item storage box 5 after the bottom has been raised.

[0139] Increasing the distance h21 from the bottom surface portion 220 to the slit portion 282 in the height direction of the main body 210 is advantageous in enhancing the bottom-raising effect of the item storage box 5. From this perspective, it is preferable that the distance h21 be equal to or greater than 1 / 2 of the height h20 of the main body 210. On the other hand, if the distance h21 is too large, the amount of items that can be stored in the item storage box 5 after deformation will be extremely small. From this perspective, it is preferable that the distance h21 be equal to or less than 4 / 5 of the height h20.

[0140] Increasing the distance h22 from the bottom surface portion 220 to the slit portion 284 in the height direction of the main body 210 is advantageous in enhancing the bottom-raising effect of the item storage box 5. From this perspective, it is preferable that the distance h22 be equal to or greater than 1 / 2 of the height h20 of the main body 210. On the other hand, if the distance h22 is too large, the amount of items that can be stored in the item storage box 5 after deformation will be extremely small. From this perspective, it is preferable that the distance h22 be equal to or less than 4 / 5 of the height h20.

[0141] Slit portion 282 and slit portion 284 are formed at positions that overlap each other in a side view. This makes it easier to arrange piece 272 inserted into slits 283 and 285 parallel to bottom portion 220.

[0142] The cut lines 250 are formed only on the bottom surface portion 220. In this case, the cut lines 250 do not pass through the boundaries between the bottom surface portion 220 and each of the side surface portions 232, 234, 236, and 238, making it easier to make cuts along the cut lines 250.

[0143] The cut line 250 is made up of the cut portion 251 and the cut portion 252, and the cut portion 253 and the cut portion 254. This makes it possible to realize the cut line 250 for forming the segment 272 with a simple configuration.

[0144] The cut portions 251 and 252 are aligned in a straight line, which makes it easier to make cuts along the cut portions 251 and 252.

[0145] The cut portions 253 and 254 are aligned in a straight line, which makes it easier to make cuts along the cut portions 253 and 254.

[0146] The cutout portions 253 and 254 extend perpendicular to the side surface portion 232. In this case, the length of each of the cutout portions 253 and 254 can be minimized. This also makes it easier to make cuts along each of the cutout portions 253 and 254.

[0147] Increasing the length of segment 272 is advantageous in preventing segment 272 from accidentally slipping out of slits 283 and 285. From this perspective, the length of segment 272 is preferably 1.2 times or more, and more preferably 1.4 times or more, the distance d20 from side surface portion 232 to side surface portion 234. From a similar perspective, the length of segment 272 is preferably 2 cm or more longer than distance d20, and more preferably 4 cm or more longer. On the other hand, if the length of segment 272 is too long, it may be difficult to secure segment portion 270 in main body 210 before deformation. From this perspective, the length of segment 272 is preferably 1.8 times or less the distance d20. From a similar perspective, the difference between the length of segment 272 and distance d20 is preferably 8 cm or less.

[0148] Increasing the width w21 of the piece 272 allows the piece 272 to come into contact with a wider area of ​​the item, which is advantageous for stably supporting the item in the item storage box 5 after the bottom has been raised. Furthermore, increasing the width w21 makes it less likely that debris from the item (for example, paper dust from tissue paper) will fall outside the main body 210, and also reduces the item's exposure to the outside air, making it more hygienic. From this perspective, the width w21 is preferably at least ¼ of the width w20 of the side portion 232, and more preferably at least ½. On the other hand, if the width w21 is too large, it may be difficult to secure the piece portion 270 in the main body 210 before deformation. From this perspective, the width w21 is preferably no more than ¾ of the width w20.

[0149] The width of side surface portion 232 and side surface portion 234 is greater than the width of side surface portion 236 and side surface portion 238. By providing slit portions 282, 284 in the pair of side surface portions (side surface portion 232 and side surface portion 234) that are relatively wider in this way, it becomes easier to ensure that piece 272 has a sufficient length.

[0150] The cut line 262 includes a vertical cut portion 262a, a vertical cut portion 262b, and a horizontal cut portion 262c. This allows the cut line 262 for forming the slit 283 to be realized with a simple configuration.

[0151] The vertical cut portions 262a and 262b and the horizontal cut portion 262c are all aligned in a straight line, which makes it easy to make cuts along the vertical cut portions 262a and 262b and the horizontal cut portion 262c.

[0152] The cut line 262 consists only of a vertical cut portion 262a, a vertical cut portion 262b, and a horizontal cut portion 262c. In this case, the portion 282a surrounded by the cut line 262 is not cut off from the main body 210, so that the portion 282a can be brought into contact with the protruding portion 272a of the piece 272. This makes it even more unlikely that the piece 272 will accidentally come out of the slit 283.

[0153] The cut line 264 includes a vertical cut portion 264a, a vertical cut portion 264b, and a horizontal cut portion 264c. This allows the cut line 264 for forming the slit 285 to be realized with a simple configuration.

[0154] The vertical cut portions 264a and 264b, and the horizontal cut portion 264c are all aligned in a straight line, which makes it easy to make cuts along the vertical cut portions 264a and 264b and the horizontal cut portion 264c.

[0155] The cut line 264 consists only of a vertical cut portion 264a, a vertical cut portion 264b, and a horizontal cut portion 264c. In this case, the portion 284a surrounded by the cut line 264 is not cut off from the main body 210, so that the portion 284a can be brought into contact with the protruding portion 272a of the piece 272. This makes it even more unlikely that the piece 272 will accidentally come out of the slit 285.

[0156] Letters or a design are printed on the protruding portion 272a of the piece 272. By printing letters or a design on the protruding portion 272a, which becomes visible from the outside of the main body 210 after deformation, the aesthetic appearance of the main body 210 after deformation can be improved.

[0157] The letters or designs are printed on the top surface of the protruding portion 272a. By printing on the top surface, which is easily visible, the letters or designs can be made to stand out.

[0158] If an advertising slogan is printed on the outlet portion 272a, the outlet portion 272a can be used as advertising space. If advertisers are recruited, it is possible to earn advertising revenue. If this revenue is used to cover the manufacturing costs of the item storage box 5, the product price of the item storage box 5 can be kept low.

[0159] Letters or designs are printed on the lower portion 210a of the inner surface of the main body 210. By printing letters or designs on the lower portion 210a of the main body 210, which becomes visible from the outside after the deformation, the aesthetic appearance of the main body 210 after the deformation can be improved.

[0160] If an advertising slogan is printed on the lower portion 210a, the lower portion 210a can be used as advertising space. If advertisers are solicited, advertising revenue can be earned. If this revenue is used to cover the manufacturing costs of the item storage box 5, the product price of the item storage box 5 can be reduced.

[0161] If the fragrance section 212 is provided in the lower portion 210a, it is possible to spread a fragrance around the deformed main body 210. That is, by peeling off the seal 214 after the main body 210 is deformed, the fragrance in the fragrance section 212 can be diffused around the main body 210. Furthermore, since the seal 214 is affixed to the fragrance section 212, the user can choose whether or not to spread a fragrance around the main body 210 by whether or not to peel off the seal 214. Other effects of the item storage box 5 are the same as those of the item storage boxes 1 to 3.

[0162] In this embodiment, the case where the shape of the segment 272 is rectangular has been exemplified. However, the segment 272 may have a tapered shape, for example, as shown in Fig. 44. In this case, the task of inserting the segment 272 can be facilitated by inserting the segment 272 into the slits 283, 285 from the tapered portion.

[0163] In the present embodiment, the horizontal cut portion 262c of the cut line 262 is shown as a straight line. However, the horizontal cut portion 262c may be wavy, as shown in Fig. 45. In this case, the piece 272 inserted into the slit 283 can be sandwiched between the convex portions from above and below, making it even more unlikely that the piece 272 will accidentally slip out of the slit 283.

[0164] In this embodiment, the horizontal cut portion 264c of the cut line 264 is shown as a straight line. However, the horizontal cut portion 264c may be wavy, as shown in Fig. 46. In this case, the piece 272 inserted into the slit 285 can be sandwiched between the convex portions from above and below, making it even more unlikely that the piece 272 will accidentally slip out of the slit 285.

[0165] In this embodiment, the main body 210 may have a plurality of slit portions 282 and a plurality of slit portions 284, as shown in, for example, FIGS. 47 and 48 . The plurality of slit portions 282 are provided at different positions in the height direction of the main body 210. Similarly, the plurality of slit portions 284 are provided at different positions in the height direction of the main body 210. The slit portions 282 and 284 are provided at positions that overlap each other in a side view. That is, the slit portion 282 provided on the upper side of the side surface portion 232 overlaps the slit portion 284 provided on the upper side of the side surface portion 234, and the slit portion 282 provided on the lower side of the side surface portion 232 overlaps the slit portion 284 provided on the lower side of the side surface portion 234. The segment 272 is inserted into the upper pair of slits 283, 285 or the lower pair of slits 283, 285.

[0166] When a plurality of slits 282 and a plurality of slits 284 are provided in this manner, the height of the segment 272 (the distance from the bottom surface 220) can be adjusted by inserting the segment 272 into whichever pair of slits 283, 285. This makes it possible to select the degree of bottom raising depending on the remaining amount of articles. Furthermore, by arranging the slits 282 and 284 in positions that overlap each other in a side view, the segment 272 can be easily arranged parallel to the bottom surface 220 regardless of which pair of slits 283, 285 the segment 272 is inserted into.

[0167] In this embodiment, the cut line 262 is positioned above the fold line 233. However, the cut line 262 may be positioned below the fold line 233, as shown in FIG.

[0168] In this embodiment, the cut line 264 is positioned above the fold line 235. However, the cut line 264 may be positioned below the fold line 235, for example, as shown in FIG.

[0169] In this embodiment, the case where the cut line 262 is formed along a single non-circular line has been exemplified. However, the cut line 262 may be formed along a single circular line, as shown in Fig. 51, for example. In that case, the portion 282a surrounded by the cut line 262 is cut off from the side surface portion 232, and a slit 283 having the same shape and size as the portion 282a is obtained.

[0170] In the present embodiment, the case where the cut line 264 is formed along a single non-circular line has been exemplified. However, the cut line 264 may be formed along a single circular line, as shown in Fig. 52, for example. In that case, the portion 284a surrounded by the cut line 264 is cut off from the side surface portion 234, and a slit 285 having the same shape and size as the portion 284a is obtained.

[0171] In this embodiment, the cut line 262 is formed along a plurality of line segments. However, the cut line 262 may be formed along a single line segment, as shown in Fig. 53. In this figure, the cut line 262 is entirely straight.

[0172] In this embodiment, the cut line 264 is formed along a plurality of line segments. However, the cut line 264 may be formed along a single line segment, as shown in Fig. 54. In this figure, the cut line 264 is entirely straight.

[0173] In this embodiment, the cut line 250 is formed only on the bottom surface portion 220. However, the cut line 250 may be formed from the bottom surface portion 220 to the side surface portion 232, as shown in FIGS. 55 to 57, for example. In FIG. 55, the cut line 250 is formed only on the bottom surface portion 220 and the side surface portion 232. In this case, the cut piece 272 is formed from a single plate consisting of a part of the bottom surface portion 220 and a part of the side surface portion 232. On the other hand, in FIGS. 56 and 57, the cut line 250 is formed from the bottom surface portion 220 to both the side surface portion 232 and the side surface portion 234. FIG. 57 is a perspective view of the main body 210 in FIG. 56, seen from the opposite side (the side surface portion 234 side). In this case, the cut piece 272 is formed from a single plate consisting of a part of the bottom surface portion 220, a part of the side surface portion 232, and a part of the side surface portion 234. Forming the cut lines 250 from the bottom surface portion 220 to the side surface portion 232 in this manner is advantageous for increasing the width of the segment 272. Forming the cut lines 250 from the bottom surface portion 220 to both the side surface portion 232 and the side surface portion 234 is particularly advantageous for increasing the width of the segment 272. Note that the cut lines 250 may be formed only in the side surface portion 232 or only in the side surface portion 234.

[0174] In this embodiment, the cut lines 250, 262, and 264 are perforations. That is, the cut lines 250, 262, and 264 are configured so that the cuts are made along the cut lines 250, 262, and 264 only when force is applied to both sides of the cut lines 250, 262, and 264. However, the cut lines 250, 262, and 264 may be made in advance. (Sixth embodiment)

[0175] Figure 58 is a perspective view showing a sixth embodiment of an item storage box according to the present invention. Figures 59 and 60 are a plan view and a rear view, respectively, of the item storage box of Figure 58. Figures 61 and 62 are side views of the item storage box of Figure 58. The item storage box 6 is an item storage box for storing items and includes a main body 10. In this embodiment, the item is a roll of sanitary paper 92. Examples of sanitary paper 92 include tissue paper, toilet paper, paper towels, and kitchen paper. Here, roll of sanitary paper 92 refers to strip-shaped sanitary paper 92 wound around an axis parallel to its short side. A cylindrical core may be provided in the center of the sanitary paper 92, or such a core may not be provided.

[0176] The main body 10 has a main surface 12, a side surface 14, and a side surface 16. The main surface 12 is provided with an outlet forming section 20. The configuration of the outlet forming section 20 is as described in the first, second, or third embodiment. However, in this embodiment, detailed illustration of the outlet forming section 20 is omitted. The side surface 14 and the side surface 16 are a pair of side surfaces perpendicular to the central axis of the sanitary paper 92. Here, the central axis of the sanitary paper 92 refers to an imaginary axis that corresponds to the central axis of a cylinder or column when the rolled sanitary paper 92 is viewed as a column or cylinder.

[0177] In this embodiment, the main body 10 further has a cutting blade 62, as well as an insertion portion 64 and an insertion portion 66. The cutting blade 62 is a portion for cutting the sanitary paper 92 pulled out from the outlet. The cutting blade 62 is provided at a position separated from the outlet forming portion 20. Specifically, the cutting blade 62 is provided on the periphery of the main surface 12. The cutting blade 62 is formed integrally with a side surface 18 of the main body 10 (see Figure 60). The side surface 18 is a side surface that is perpendicular to the side surfaces 14 and 16. The cutting blade 62 protrudes above the main surface 12 (see Figures 61 and 62).

[0178] The insertion portion 64 is a portion that is inserted into a gap in the center of the sanitary paper 92. As shown in FIG. 61 , the insertion portion 64 is provided on the side surface 14 of the main body 10. The outer shape of the insertion portion 64 is a polygon. Preferably, the outer shape of the insertion portion 64 is a regular n-gon (n is an integer greater than or equal to 5). In this embodiment, an example is shown where n=8. The insertion portion 64 has cut lines 64a. The cut lines 64a are made up of multiple line segments connecting the center of the insertion portion 64 to each vertex. The cut lines 64a are perforations. After cutting the side surface 14 along the cut lines 64a, the tongues (triangular portions with the bases at each side of the polygon) of the insertion portion 64 can be folded inward along the periphery (each side of the polygon) of the insertion portion 64 to insert the insertion portion 64 (multiple tongues) into the center of the sanitary paper 92. In this way, the insertion portion 64 is made up of a part of the side surface 14 .

[0179] The insertion portion 66 is a portion that is inserted into the gap in the center of the sanitary paper 92. As shown in Figure 62, the insertion portion 66 is provided on the side surface 16 of the main body 10. The outer shape of the insertion portion 66 is a polygon. Similar to the outer shape of the insertion portion 64, the outer shape of the insertion portion 66 is preferably a regular n-gon. The insertion portion 66 has a cut line 66a. The cut line 66a consists of multiple line segments connecting the center of the insertion portion 66 to each vertex. The cut line 66a is a perforation. After cutting the side surface 16 along the cut line 66a, the tongue can be bent inward along the periphery of the insertion portion 66 to insert the insertion portion 66 into the center of the sanitary paper 92. In this way, the insertion portion 66 consists of part of the side surface 16. The insertion portions 64 and 66 are disposed in positions that completely overlap each other when viewed from a direction perpendicular to the side surfaces 14 and 16. The entire main body 10, including the cutting blade 62, the insertion portions 64 and 66, is made of the same material. The other configurations of the main body 10 are as described in the first embodiment.

[0180] An example of how to use the item storage box 6 will be described with reference to Figures 63 to 65. Figure 63 is a perspective view showing the item storage box 6 when in use. Figure 64 is a view for explaining the structure of the end surface along line EE in Figure 63. The sanitary paper 92 is not shown in Figure 63. To use the item storage box 6, first, the outlet 50 is formed in the outlet forming section 20 as described in the first embodiment. Then, a cut is made in the side surface 14 along the cut line 64a of the insertion portion 64, and a cut is made in the side surface 16 along the cut line 66a of the insertion portion 66. Then, the insertion portions 64 and 66 are folded inward of the main body 10 and inserted into the center of the sanitary paper 92.

[0181] Next, as shown in Figure 64, one end of the sanitary paper 92 is pulled to pull it out of the main body 10. Then, as shown in Figure 65, the pulled-out sanitary paper 92 is pressed against the tip of the cutting blade 62 and cut. This allows a cut piece of sanitary paper 92 of the desired length to be obtained.

[0182] An example of a manufacturing method for the item storage box 6 will be described with reference to Figures 66 and 67. First, a sheet 70 of sufficient size is prepared, and the sheet 70 is cut into the shape shown in Figure 66. In this example, the sheet 70 is made of a single piece of cardboard. The cut sheet 70 includes a portion 12p that will become the main surface 12, a portion 13p that will become the bottom surface of the main body 10 (the surface opposite to the main surface 12), a portion 14p that will become the side surface 14, a portion 16p that will become the side surface 16, a portion 18p that will become the side surface 18, and a portion 19p that will become the remaining side surfaces of the main body 10 (the sides other than the sides 14, 16, and 18). An outlet forming portion 20 is formed in the portion 12p. Insertion portions 72 are connected to three sides of the portion 12p. An insertion portion 64 is formed in the portion 14p. An adhesive margin portion 74 is connected to two sides of the portion 14p. An insertion portion 66 is formed in the portion 16p. Two sides of portion 16p are connected to margin portions 76. Portion 18p is connected to cutting blade 62. Note that Figure 66 shows the inner surfaces (inner surfaces of main body 10) of portions 12p, 13p, 14p, 16p, 18p, and 19p.

[0183] Next, the sheet 70 is valley-folded along folds F1 to F8. Fold F1 is located at the boundary between portion 12p and portion 16p. Fold F2 is located at the boundary between portion 12p and each insertion portion 72. Fold F3 is located at the boundary between portion 13p and portion 14p. Fold F4 is located at the boundary between portion 14p and each glue tab 74. Fold F5 is located at the boundary between portion 13p and portion 16p. Fold F6 is located at the boundary between portion 16p and each glue tab 76. Fold F7 is located at the boundary between portion 13p and portion 18p. Furthermore, fold F8 is located at the boundary between portion 13p and portion 19p.

[0184] Next, the adhesive tab 74 is glued to the inner surfaces of the portions 18p and 19p, and the adhesive tab 76 is glued to the inner surfaces of the portions 18p and 19p. Then, as shown in FIG. 67, the inserting portion 72 is inserted into the space surrounded by the portions 13p, 14p, 16p, 18p, and 19p so that the inserting portion 72 overlaps the inner surfaces of the portions 14p, 18p, and 19p. This completes the storage box 6 (main body 10) shown in FIGS. 58 to 62. In this example, the main body 10 is obtained from a single sheet 70. The inserting portion 72 may or may not be glued to the inner surfaces of the portions 14p, 18p, and 19p. In the former case, sanitary paper 92 must be placed in the space prior to gluing. In the latter case, a main body 10 having an openable main surface 12 is obtained.

[0185] The effects of the storage box 6 will now be described. The main body 10 of the storage box 6 has a cutting blade 62. This makes it easier to cut the sanitary paper 92 neatly compared to cutting the sanitary paper 92 pulled out of the main body 10 by hand.

[0186] The cutting blade 62 is located at a position separated from the outlet forming section 20. In this case, after cutting, the sanitary paper 92 pulled out of the main body 10 remains between the outlet forming section 20 and the cutting blade 62. This has the advantage that the sanitary paper 92 can be easily picked up the next time it is pulled out.

[0187] The cutting blade 62 is provided on the periphery of the main surface 12. In this case, by providing the cutting blade 62 adjacent to the side surface of the main body 10, the main body 10 having the cutting blade 62 can be realized with a simple configuration. In fact, in the item storage box 6, the cutting blade 62 is provided adjacent to the upper end of the side surface 18.

[0188] The main body 10 has insertion portions 64, 66. This makes it difficult for the central axis of the sanitary paper 92 to move. This is advantageous for stably pulling out the sanitary paper 92 from the main body 10.

[0189] The insertion portion 64 is made up of a part of the side surface 14 of the main body 10. This allows the main body 10 having the insertion portion 64 to be realized with a simple configuration. Similarly, the insertion portion 66 is made up of a part of the side surface 16 of the main body 10. This allows the main body 10 having the insertion portion 66 to be realized with a simple configuration.

[0190] When the outer shape of each insertion portion 64, 66 is a regular n-gon (n is an integer of 5 or more), the outer shape is close to a circle. This makes it easier to smoothly rotate the sanitary paper 92 with the insertion portion 64, 66 inserted through the center.

[0191] The entire body 10, including the cutting blade 62, the insertion portion 64, and the insertion portion 66, is made of the same material. This contributes to reducing the manufacturing cost of the item storage box 6. Other effects of the item storage box 6 are the same as those of the item storage boxes 1 to 3.

[0192] In this embodiment, the outer shape of each insertion section 64, 66 is an n-sided polygon (n is an integer greater than or equal to 5). However, the outer shape of each insertion section 64, 66 may also be a triangle or a square. In this case, the sanitary paper 92 will not rotate smoothly, but it will also be less likely to rotate in the reverse direction. This has the advantage that the sanitary paper 92 pulled out of the main body 10 will not easily slip back in.

[0193] In this embodiment, the cut lines 64a and 66a are perforations. That is, the cut lines 64a and 66a are configured so that the cuts are made along the cut lines 64a and 66a only when force is applied to both sides of the cut lines 64a and 66a. However, the cut lines 64a and 66a may be pre-cut.

[0194] In this embodiment, the case where both the insertion portion 64 and the insertion portion 66 are provided in the main body 10 has been exemplified. However, the main body 10 may be provided with only either the insertion portion 64 or the insertion portion 66. Alternatively, the main body 10 may be provided with neither the insertion portion 64 nor the insertion portion 66.

[0195] In this embodiment, the cutting blade 62 protrudes above the main surface 12. However, the cutting blade 62 may protrude laterally from the main surface 12, as shown in Fig. 68, for example. In this case, the cutting blade 62 can be formed integrally with the main surface 12.

[0196] In this embodiment, the case where the cutting blade 62 is provided on the main body 10 has been exemplified. However, the main body 10 does not have to be provided with the cutting blade 62. In that case, the sanitary paper 92 pulled out from the main body 10 may be cut by hand or by the tip of the holding portion 22a or the tip of the holding portion 24a.

[0197] In this embodiment, the case where only one roll of sanitary paper 92 is stored in the main body 10 has been illustrated. However, the main body 10 may store multiple rolls of sanitary paper 92, as shown in Figures 69 and 70, for example. Figure 70 is a diagram illustrating the structure of the end surface along line FF in Figure 69. In this example, two rolls of sanitary paper 92 are stored in the main body 10. A partition 10a is provided within the main body 10 to separate the two rolls of sanitary paper 92. The main surface 12 has multiple outlet forming sections 20 to accommodate the multiple rolls of sanitary paper 92. That is, one outlet forming section 20 has an outlet formed for one roll of sanitary paper 92, and the other outlet forming section 20 has an outlet formed for the other roll of sanitary paper 92.

[0198] Storing multiple sanitary paper sheets 92 in the main body 10 in this way improves convenience for the user. For example, if multiple different types of sanitary paper sheets 92 are stored in the main body 10, the user can selectively remove the appropriate sanitary paper sheet 92 from the main body 10 depending on the application. Also, by providing multiple outlet forming sections 20 to accommodate multiple sanitary paper sheets 92, the multiple sanitary paper sheets 92 can be removed from separate outlets. This prevents the multiple sanitary paper sheets 92 from interfering with each other, allowing each sanitary paper sheet 92 to be removed smoothly.

[0199] The present invention is not limited to the above-described embodiment, and various modifications are possible. In the above-described embodiment, the entire main body 10 is made of a single material. However, the main body 10 may be made of multiple materials. For example, it is conceivable to use plastic or metal as the material of the cutting blade 62, while using cardboard as the material of the remainder of the main body 10 (portions other than the cutting blade 62). Alternatively, it is conceivable to use cardboard as the material of the main surface 12, while using another material as the material of the remainder of the main body 10 (portions other than the main surface 12). Examples of other materials include cardboard, CNF (cellulose nanofiber), wood, plastic, or metal.

[0200] In the above embodiment, the case where the restricting portion 22b and the restricting portion 24b reach the crease 34 and the crease 32, respectively, has been exemplified. However, the restricting portion 22b and the restricting portion 24b do not have to reach the crease 34 and the crease 32, respectively, as shown in FIG. 71 , for example. In the same figure, one restricting portion 22b (the leftmost restricting portion 22b) reaches the crease 34, while the remaining two restricting portions 22b do not reach the crease 34. Similarly, one restricting portion 24b (the rightmost restricting portion 24b) reaches the crease 32, while the remaining two restricting portions 24b do not reach the crease 32.

[0201] In the above embodiment, the case where the protrusion 26 is formed not only on the side end 22c of the restricting portion 22b but also on the side end 22d of the holding portion 22a has been exemplified. Also, the case where the protrusion 28 is formed not only on the side end 24c of the restricting portion 24b but also on the side end 24d of the holding portion 24a has been exemplified. However, the protrusions 26 and 28 may be formed only on the side end 22c and the side end 24c, respectively, as shown in FIG. 72, for example. In this case, the degree of freedom of deformation of the holding portion 22a and the holding portion 24a is increased, making it easier to smoothly remove an article.

[0202] In the above embodiment, a case has been described in which a plurality of protrusions 26 are formed on one side end 22c and a plurality of protrusions 28 are formed on one side end 24c. However, only one protrusion 26 may be provided on one side end 22c, as shown in Fig. 73, for example. In the same figure, only one protrusion 28 is also provided on one side end 24c.

[0203] In the above embodiment, the folding pieces 22 and 24 have the same shape. However, the folding pieces 22 and 24 do not have to have the same shape, as shown in Fig. 74, for example.

[0204] In the above embodiment, the bending piece 22 is divided into a holding portion 22a and a restricting portion 22b. Also, the bending piece 24 is divided into a holding portion 24a and a restricting portion 24b. However, as shown in FIG. 75, the bending piece 22 does not have to be divided into a holding portion and a restricting portion. In this figure, the bending piece 24 is also not divided into a holding portion and a restricting portion. In this case, the entire bending piece 22, 24 functions as both a holding portion and a restricting portion.

[0205] In the above embodiment, the restricting portion 22b and the restricting portion 24b are provided on both sides of the holding portion 22a and the holding portion 24a, respectively. However, the restricting portion 22b and the restricting portion 24b may be provided on only one side of the holding portion 22a and the holding portion 24a, respectively, as shown in FIG.

[0206] In the above embodiment, the portion 42a of the cut line 42 is wavy. However, the portion 42a may be curved and bulged toward the holding portion 22a or the holding portion 24a, as shown in Fig. 77. In the figure, the portion 42a is curved and bulged toward the holding portion 22a.

[0207] When the portion 42a of the cut line 42 is curved and bulges toward the holding portion 22a, the tip of the holding portion 22a is concave and the tip of the holding portion 24a is convex. When the tip of the holding portion 22a is concave, the article is more likely to wrinkle as it passes near the tip. This causes the article to expand in the vertical direction of the outlet forming portion 20, making it easier for the article to remain sandwiched between the holding portion 22a and the holding portion 24a. This makes it less likely for an article pulled out of the outlet to fall into the main body 10. Furthermore, when the tip of the holding portion 24a is convex, the tip is more likely to come into contact with the article. This further reduces the likelihood that an article pulled out of the outlet will fall into the main body 10.

[0208] Alternatively, the portion 42a of the cut line 42 may be straight, as shown in Fig. 78. In this case, it becomes easier to make the cut along the portion 42a.

[0209] In the above embodiment, the side of the main body 10 may be openable and closable, as shown in, for example, Figures 79 and 80. Figures 79 and 80 show the side 15 of the main body 10 in an open state and a closed state, respectively. The side 15 includes an upper plate 15a and a lower plate 15b. The upper plate 15a and the lower plate 15b are connected to the main surface 12 and the bottom surface, respectively. The upper plate 15a and the lower plate 15b are configured so that their leading ends overlap. Specifically, in the height direction of the main body 10 (the vertical direction in Figures 79 and 80), the sum of the lengths of the upper plate 15a and the lower plate 15b is greater than the height of the main body 10. The leading ends of the upper plate 15a and the lower plate 15b have slits 17a and 17b, respectively. The side 15 can be closed by engaging the slits 17a and 17b with each other (see Figure 80). Conversely, the side surface 15 can be opened by disengaging the cuts 17a and 17b (see FIG. 79). This allows items to be refilled through the side surface 15 of the main body 10.

[0210] In the above embodiment, the first and second fold lines are respectively formed as crease 32 and crease 34. However, the first and second fold lines may be simply lines printed on main surface 12 to inform the user of the fold positions.

[0211] In the above embodiment, the cut lines 42, 44, and 46 are perforations. That is, the cut lines 42, 44, and 46 are configured so that the cuts are made along the cut lines 42, 44, and 46 only when force is applied to both sides of the cut lines 42, 44, and 46. However, the cut lines 42, 44, and 46 may be made in advance. [Explanation of symbols]
