Description

Technical Field

[0001] The present invention relates to a hanging box.

Background Art

[0002] In stores that sell products such as department stores and convenience stores, a hanging box for displaying and selling products while hanging them on a hanging rod, also called a display bar, is known.

[0003] As one form of a conventional hanging box, a hanging surface is formed so as to extend from the upper part of the back plate of a case-shaped cardboard box, and the hanging rod is passed through a hole or the like provided on this hanging surface, etc., and the products stored in the cardboard box are hung and displayed for sale (Patent Documents 1 and 2 below).

[0004] This form of hanging box has a problem that the hanging surface gets in the way when making a flat display without using the hanging surface or when packing a large number of them in a cardboard box at the time of shipping or transportation. In a store that sells products, the display form and arrangement of products may be changed. For example, a certain product may be changed from a hanging display to a flat display or from a flat display to a hanging display. The conventional form in which the hanging surface extends integrally from the back plate of Patent Document 1 and Patent Document 2 is not suitable for such a change in the display form.

[0005] As another form of a conventional hanging box, a telescopic member is integrally attached to the lower part of a hanging tool so that the hanging tool can be pulled out upward as needed for use, which is disclosed in Patent Document 3 below. The hanging box disclosed in Patent Document 3 can store the hanging tool at a position below the upper edge of the back plate, and when making a flat display or when packing a large number of them in a cardboard box at the time of shipping or transportation, the hanging tool can be stored so as not to get in the way.

[0006] However, the telescopic member of the suspension box disclosed in Patent Document 3 is composed of a sheet material cut into a U-shape, and the suspension tool is sandwiched between two sheet-like members, namely a back plate and a clamping plate, including this U-shaped sheet material. Therefore, it is necessary to stretch the telescopic member that is only cut into a U-shape by pulling between the two sheet-like members of the back plate and the clamping plate, and there is a possibility that the suspension tool cannot be telescoped smoothly. In particular, this possibility increases when the rigidity of the paper material constituting the suspension box is high or when the material is difficult to deform.

[0007] As another form of the conventional suspension box, by pulling up the portion overlapping the lid portion of the box top surface, a hanging portion in the shape of a triangular roof straddling the upper edge of the front portion and the upper edge of the back portion is formed, and a hanging rod is inserted into a hanging hole opened in the hanging portion so that the product can be hung and displayed (Patent Documents 4 and 5 below).

[0008] The suspension box disclosed in Patent Documents 4 and 5 is provided with a lid portion between the upper edge of the front portion and the upper edge of the back portion, and on the upper end edge of the front portion, a hanging exposed surface, a hanging storage surface, and a hanging insertion piece are sequentially connected in series via a fold line, and the extension length of the hanging exposed surface is set to be substantially equal to the distance between the oppositely arranged back portion and front portion, that is, the depth of the lid portion.

[0009] The suspension box disclosed in Patent Document 4 is provided with slits at two locations between the back portion and between the back portion and the lid portion. When the insertion piece is inserted into the slit provided in the back portion, the hanging storage surface overlaps a part of the back portion, and the hanging exposed surface overlaps the lid portion, and the hanging portion is in a stored state. On the other hand, in the state where the insertion piece is inserted into the slit between the back portion and the lid portion, the hanging storage surface and the hanging exposed surface are configured to form a triangular roof-shaped hanging portion above the lid portion.

[0010] The suspension box disclosed in Patent Document 5 forms the first locking claw by forming slits at both ends of the fold line between the suspension exposed surface and the suspension storage surface, and forms the second locking claw by forming slits at both ends of the fold line between the suspension storage surface and the insertion piece. Then, the insertion piece and the suspension storage surface are inserted into the slit provided between the back surface portion and the lid portion, and the suspension lower portion is stored and maintained by locking the slit and the second locking claw. By pulling out the suspension storage surface and locking the slit and the first locking claw, the suspension storage surface and the suspension exposed surface are configured to form a triangular roof-shaped suspension lower portion above the lid portion.

[0011] Since the suspension box disclosed in Patent Document 4 and Patent Document 5 can store the suspension lower portion, when it is placed flat or when a large number of them are packed in a cardboard box during shipping or transportation, the suspension lower portion does not get in the way. In addition, the suspension lower portion can be formed without requiring an expansion member like the suspension box of Patent Document 3.

Summary of the Invention

Problems to be Solved by the Invention

[0013] However, the suspension box disclosed in Patent Document 4 has a problem that when the insertion piece is inserted into the slit on the back surface portion, a step is formed on the back surface and it does not become flat, so there is a risk of being caught by a conveying mechanism or the like during the production stage or the like.

[0014] In addition, the hanging box disclosed in Patent Document 5 is provided with a first locking piece to prevent the hanging storage surface from coming off and the hanging exposed surface from rising. However, since the first locking piece has a structure in which slits are formed at both ends of the fold line, there is a problem that it is easily damaged when pulling up the hanging storage surface.

[0015] Furthermore, in the hanging boxes of Patent Document 4 and Patent Document 5, since the widths of the hanging exposed surface and the hanging storage surface are the same as the width of the lid portion, the height of the triangular roof-shaped hanging portion is the distance between the upper edge of the front portion and the upper edge of the rear portion, that is, the depth of the lid portion is √3 / 2 or less. For this reason, in the case of a thin box with a short distance between the front portion and the rear portion, there is a problem that a hanging portion with sufficient height cannot be formed.

[0016] Therefore, the main problem of the present invention is to solve the problems of the above-mentioned conventional hanging box, to make it difficult to break during the operation of storing and exposing the hanging portion, and further, to provide a hanging box with a structure that can expose a hanging portion with a certain height even in the case of a thin box with a short distance between the front portion and the rear portion.

[0018] The second means is a suspension box according to the first means, wherein the restoring force between the upper edge of the front part and the suspended front part is weaker than the restoring force between the suspended front part and the suspended back part.

[0019] The third means is a suspension box according to the first means, wherein the lower edge of the front-side suspension hole coincides with or is located on the upper edge of the front part.

[0021] The fifth means is a suspension box according to the fourth means, wherein the front-side suspension hole and the back-side suspension hole are symmetrically located with respect to the fold line between the suspended front part and the suspended back part, and a part of the front-side suspension hole is located between the fold line between the suspended front part and the suspended back part and the suspended front part storage fold line.

[0022] The sixth means is a suspension box according to the fourth means, wherein the restoring force between the upper edge of the front part and the suspended front part is weaker than the restoring force of the suspended front part storage fold line.

[0023] The seventh means is a suspension box according to the first means, wherein a take-out piece is formed at the center of the fold line between the suspended back part and the second insertion piece and both ends are not cut, and the suspended front part is configured to overlap the lid part when the suspended back part and the second insertion piece are inserted into the slit.

[0024] The eighth means is a suspension box according to the first means, having locking claws at both ends of the second insertion piece, and the locking claws and the slit are locked.

[0025] The ninth means is The hanging box has a middle box part having a back plate part, In the space surrounded by the front part, the back part and the lid part, this middle box part is internally provided so that the back plate part faces the back part, and at least a hanging back part and a second insertion piece are inserted between the back plate part and the back part. The hanging box according to the first means, wherein the portion inserted between the back plate part and the back part is clamped by the back plate part and the back part.

Embodiments for Carrying Out the Invention

[0028] Next, embodiments of the present invention will be described in detail below with reference to FIGS. 1 to 14. However, the present invention is not limited to these embodiments. Also, in the present invention, the target article to be contained in the hanging box is not limited.

[0029] (First Embodiment) The hanging box 1 of the first embodiment will be described with reference to FIGS. 1 to 7. As shown in FIG. 1, the hanging box 1 of this embodiment has a rectangular parallelepiped-shaped box main body 10 in which articles are stored, and a hanging part 20 formed so as to be storable in the upper part of the box main body 10. The state in which the hanging part 20 is stored is shown in FIG. 2. This hanging box 1 is formed by assembling the sheet material 1S as shown in the exploded state in FIG. 3.

[0030] In the deployed state of the suspension box 1 of this embodiment, the left side surface 11, the front surface 12, the right side surface 13, the back surface 14, and the pasting margin 15 are sequentially connected via fold lines 31, 32, 33, 34 arranged in parallel. Also, via fold lines 35, 36, the lid portion 16 and the first insertion piece 17 are sequentially connected to the upper edge of the back surface 14, and via fold lines 41, 42, 43, the suspended front surface 21, the suspended back surface 22, and the second insertion piece 23 are sequentially connected to the upper edge of the front surface 12. Furthermore, a slit 51 is formed between the fold lines 35, 35 between the back surface 14 and the lid portion 16.

[0031] On the other hand, in the deployed state of the suspension box 1 of this embodiment, the bottom portion 18 and the third insertion piece 19 are sequentially connected to the lower edge of the front surface 12 via fold lines 37, 38. Also, flap portions 71, 72... are connected to the upper edges and lower edges of the left side surface 11 and the right side surface 13 via fold lines 61, 62...

[0032] The box body portion 10 of the suspension box 1 of this embodiment is formed by bending the fold lines 31, 32, 33, 34 of the sheet material 1S in the deployed state in the same direction, adhering the pasting margin 15 to the inside of the left side surface 11 to form a rectangular tube shape, then bending the fold lines 61, 62 to position the respective flap portions 71, 72 on the upper and lower openings of the rectangular tube, further bending the fold lines 35, 36 to overlap the lid portion 16 on the flap portion 71 extending from the upper edges of the left side surface 11 and the right side surface 13, inserting the first insertion piece 17 between the front surface 12 and the flap portions 71, 71 to seal the upper opening with the lid portion 16, and further bending the fold lines 37, 38 to overlap the bottom portion 18 on the flap portions 72, 72 extending from the lower edges of the left side surface 11 and the right side surface 13, inserting the third insertion piece 19 between the back surface 14 and the flap portions 72, 72 to seal the lower opening with the bottom portion 18.

[0033] Note that, in the box main body 10 of this embodiment, a window portion 12W is formed in the front portion 12 that allows the articles stored in the box main body to be visible from the outside, but this window portion 12W may be omitted. Further, a transparent sheet or plate can be arranged in the front portion 12 or inside the box main body so as to block the window portion 12W. Such a transparent sheet or plate can be composed of a known resin material, a paper material impregnated with a drug, or the like.

[0034] On the other hand, the hanging portion 20 of the hanging box 1 of this first embodiment has an extension length L1 of the hanging front portion 21, that is, the distance from the upper edge of the front portion 12 to the fold line 42 between the hanging front portion 21 and the hanging back portion 22, which is substantially the same as the distance L2 between the upper edge of the front portion 12 and the upper edge of the back portion 14. The hanging front portion 21, the hanging back portion 22, and the second insertion piece 23 are bent along the fold lines 41, 42, and 43, and the hanging front portion 21 is overlapped on the lid portion 16. At the same time, the hanging back portion 22 and the second insertion piece 23 are inserted into the slit 51, and the hanging back portion 22 and the second insertion piece 23 are positioned so as to overlap the inside of the box main body of the back portion 14, and are assembled in a stored state.

[0035] Also, the hanging portion 20 of the hanging box 1 according to the present invention is configured such that the distance L1 from the upper edge of the front portion 12 to the fold line 42 between the hanging front portion 21 and the hanging back portion 22 is equal to the distance from the fold line 42 between the hanging front portion 21 and the hanging back portion 22 to the upper edge of the back portion 14. Therefore, when the hanging portion 20 is pulled out from the slit 51 in the above storage state, leaving only the second insertion piece 23, it is assembled in an exposed state in a triangular roof shape by the hanging front portion 21 and the hanging back portion 22 above the lid portion 16.

[0036] The hanging part 20 of the hanging box 1 of this embodiment has a front-side hanging hole 81 formed in the hanging front part 21 and a back-side hanging hole 82 formed in the hanging back part 22. The front-side hanging hole 81 and the back-side hanging hole 82 have portions that are symmetrically located with respect to the fold line 42 between the hanging front part 21 and the hanging back part 22. In a state where the hanging part 20 is exposed in a triangular roof shape, a single hanging hole 80 is configured to allow a hanging rod to be inserted from the front-side hanging hole 81 on the front part side to the back-side hanging hole 82 on the back part side, or from the back-side hanging hole 82 on the back part side to the front-side hanging hole 81 on the front part side. Note that the shapes of the front-side hanging hole 81 and the back-side hanging hole 82 do not necessarily have to be the same, but it is desirable that they have the same shape.

[0037] Also, the hanging box 1 of this embodiment has locking claws 23t, 23t at both ends of the second insertion piece 23. These locking claws 23t, 23t are configured such that both ends of the edge of the second insertion piece 23 on the fold line side slightly protrude from the fold line 43 between the hanging back part 22 and the second insertion piece 23. After the hanging back part 22 and the second insertion piece 23 are inserted into the slit 51 once, when an operation is performed to pull out the hanging back part 22 and the second insertion piece 23 from the slit 51, only the hanging back part 22 is pulled out from the slit 51 and the locking claws 23t are locked to both ends of the slit 51, and the second insertion piece 23 is configured to remain in the slit 51. The hanging box 1 of this embodiment is prevented from unintentionally coming out completely from the slit 51 to the second insertion piece 23 when pulling out the hanging part 20 from the stored state to the exposed state by these locking claws 23t, and the fold line 43 between the hanging back part 22 and the second insertion piece 23 is positioned at the upper edge of the back part 14, so that a triangular roof-shaped hanging part is formed above the lid part 16.

[0038] On the other hand, in the suspension box 1 of the embodiment, the connection length L6 between the front part 12 and the suspended front part 21 is shorter than the length L5 of the upper edge of the front part 12. When the connection length L6 between the front part 12 and the suspended front part 21 is made shorter than the length L5 of the upper edge of the front part 12, the restoring force when bent along the fold line 41 between the front part 12 and the suspended front part 21 is smaller than at least the shape in which the suspended front part extends from the entire length L5 of the upper edge of the front part 12. For this reason, in the stored state of the suspended part 20, it is difficult for a part of the suspended back part 22 inserted into the slit 51 to come out so as to float from the slit 51, and it is difficult to form a gap between the lid part 16 and the suspended front part 21. Therefore, in the stored state of the suspended part 20, there is no need to take measures to make it difficult for the suspended back part 22 to come out of the slit 51, such as forming locking claws by slightly protruding both ends of the edge on the fold line side of the suspended back part 22 from the fold line 42 between the suspended front part 21 and the suspended back part 22. As a result, for example, the force required to pull out the suspended back part 22 from the slit 51 can be weakened, and when the operation of pulling out the suspended part 20 from the stored state is performed, the suspended part is less likely to be damaged. In addition, it can be smoothly pulled out from the stored state, and it can be easily returned to the stored state again, facilitating the switching between suspended display and flat display.

[0039] On the other hand, in the suspension box 1 of the present embodiment, a take-out piece 24 is formed on the fold line 42 between the suspension front part 21 and the suspension back part 22 to facilitate pulling up the suspended part 20 in the stored state. This take-out piece 24 is arranged at a position separated from both edges of the fold line 42, and by providing a substantially U-shaped slit on the fold line 42, when the fold line 42 is bent, it is formed to be slightly convex toward the back side from the upper edge of the back part 14 in particular. In the illustrated form, the take-out piece 24 is formed at one location in the center of the fold line 42 between the suspension front part 21 and the suspension back part 22, but it may be provided at two or more locations at positions separated from both ends of the fold line 42. Also, particularly when providing this take-out piece 24, it is desirable not to form cut portions at both ends of the fold line 42 between the suspension front part 21 and the suspension back part 22. In the suspension box 1 of the present embodiment, since the entire suspension back part 22 is likely to be positioned within the slit 51 in the stored state and it is easy to pull up from the stored state, the suspended part 20 can be smoothly brought into the exposed state by simply hooking a finger on the take-out piece 24 and gently pulling it up. Also, by not forming cut portions at both ends of the fold line 42, the number of vulnerable parts on the fold line 42 between the suspension front part 21 and the suspension back part 22 is reduced, and when pulling up with the take-out piece 24 and a finger, the possibility that the fold line 42 between the suspension front part 21 and the suspension back part 22 breaks is decreased.

[0040] In the hanging box 1 of this embodiment, it is desirable that the restoring force at the fold line 41 between the upper edge of the front part 12 and the hanging front part 21 is weaker than the restoring force at the fold line 42 between the hanging front part 21 and the hanging back part 22. When the restoring force at the fold line 41 between the upper edge of the front part 12 and the hanging front part 21 is weaker than the restoring force at the fold line 42 between the hanging front part 21 and the hanging back part 22, in the stored state, due to the restoring force at the fold line 42 between the hanging front part 21 and the hanging back part 22, the hanging back part 22 comes into contact with the back part 14 of the box main body part 10, and particularly the hanging back part 22 presses the back part 14 and contacts it in a way that increases friction. On the other hand, due to the restoring force of the fold line between the upper edge of the front part 12 and the hanging front part 21, it becomes difficult for the hanging back part 22 to come out of the slit 51, so that the stored state of the hanging part 20 is preferably maintained. Also, it is easy to maintain the hanging part returning from the exposed state to the stored state again, and it becomes easy to switch between hanging display and flat placement display.

[0041] On the other hand, in the hanging box 1 of this embodiment, it is desirable that the lower edge 81E of the front-side hanging hole 81 coincides with or is located on the upper edge of the front part 12. The front-side hanging hole 81 in the illustrated form is in the shape of a rounded triangle, and its bottom edge 81E is configured to coincide with the upper edge of the front part 12. When the lower edge of the front-side hanging hole 81 coincides with or is located on the upper edge of the front part 12, the length of the fold line 41 between the upper edge of the front part 12 and the hanging front part 21 in the hanging part 20 becomes shorter. Therefore, the restoring force at the fold line 41 between the upper edge of the front part 12 and the hanging front part 21 in the hanging part 20 is weakened, and in the stored state, it becomes difficult for the hanging back part 22 to float up from the slit 51, and it becomes easier to preferably maintain the stored state of the hanging part 20. Also, it is easy to maintain the hanging part returning from the exposed state to the stored state again, and it becomes easy to switch between hanging display and flat placement display. Note that it is desirable not to form cuts or the like at both edge ends of the fold line 41 between the upper edge of the front part 12 and the hanging front part 21. When pulling up the hanging part 20 from the stored state, it becomes difficult for the fold line part to be damaged.

[0042] On the other hand, as shown in the mode particularly shown in FIG. 7, it is desirable that the middle box portion 90 having the back plate portion 91 is internally provided in the space surrounded by at least the front portion 12, the back portion 14, and the lid portion 16 of the box main body portion 10 so that the back plate portion 91 faces the back portion 14. The middle box portion 90 can be exemplified by a rectangular parallelepiped shape that matches the inner dimensions of the box main body portion 10. Also. The front side can be opened so that the product can be visually recognized from the front side 12. The hanging box 1 of this mode has at least a hanging back portion 22 and a second insertion piece 23 inserted between the back plate portion 91 of the middle box portion 90 and the back portion 14 of the box main body portion 10, and the portion inserted between the back plate portion 91 and the back portion 14 is sandwiched between the back plate portion 91 and the back portion 14. By sandwiching the hanging back portion 22 and the second insertion piece 23 between the back plate portion 91 of the middle box portion 90 and the back portion 14 of the box main body portion 10, the stored state of the hanging portion 20 is preferably maintained.

[0043] The specific assembly configuration of the middle box portion 90 is not limited, but it is desirable that the middle box portion 90 is also assembled by bending a sheet material cut into an appropriate shape in the same manner as the box main body portion 10. For this assembly, known box body forming techniques can be used.

[0044] (Second Embodiment) Next, the hanging box of the second embodiment will be described with reference to FIGS. 8 to 13. The hanging box 2 of this second embodiment has the same operational effects as the hanging box of the first embodiment. The hanging box 2 of the present embodiment has a box main body portion 10 and a hanging portion 20 assembled from a single sheet material 2S as in the first embodiment, but the configuration of the hanging portion 20 is partially different from that of the first embodiment. The same configuration as that of the first embodiment is as described above, and the same reference numerals are given in the drawings and the description is omitted, and the configuration peculiar to the hanging box 2 of the second embodiment will be mainly described.

[0045] In the hanging box 1 of the first embodiment, the distance L1 from the upper edge of the front part 12 to the fold line 42 between the hanging front part 21 and the hanging back part 22 is substantially the same as the distance L2 between the upper edge of the front part 12 and the upper edge of the back part 14. However, in the hanging part 20 of the present embodiment, the extension length L1 of the hanging front part, which is the distance from the upper edge of the front part 12 to the fold line 42 between the hanging front part 21 and the hanging back part 22, is formed longer than the distance L2 between the upper edge of the front part 12 and the upper edge of the back part 14. Further, a hanging front part storage fold line 44 parallel to the fold line 42 between the hanging front part 21 and the hanging back part 22 is provided on the hanging front part 21 so that a part of the hanging front part 21 can be inserted into the slit 51.

[0046] In the hanging part 20 of the hanging box 2 of the present embodiment, the hanging front part 21, the hanging back part 22, and the second insertion piece 23 are bent along the fold lines 41, 42, and 43. Further, the hanging front part storage fold line 44 is bent so that a part of the hanging front part 21 is overlapped on the lid part, and the other part of the hanging front part 21, the hanging back part 22, and the second insertion piece 23 are inserted into the slit 51, and the other part of the hanging front part 21, the hanging back part 22, and the second insertion piece 23 are positioned so as to overlap the inside of the box body part of the back part 14, and thus it is assembled into the storage state.

[0047] On the other hand, in the hanging box 2 of the present embodiment, in the storage state of the hanging part 20, since the part from the hanging front part storage fold line 44 to the tip of the second insertion piece 23 is positioned inside the slit 51, the extraction piece 24 for facilitating the pulling up of the hanging part 20 in the storage state is formed on the hanging front part storage fold line 44. The position, number, formation method, and effects of the extraction piece 24 can be the same as those in the first embodiment.

[0048] The hanging box 2 of the present embodiment can form a hanging part 20 having a height exceeding √3 / 2 of the distance L2 between the upper edge of the front part 12 and the upper edge of the back part 14 on the lid part 16. Therefore, even when the box body part 10 is thin and the distance between the upper edge of the front part 12 and the upper edge of the back part 14 is short, a hanging part 20 having a certain height can be formed. Note that the hanging front part storage fold line 44 is not limited to one, and a plurality of them may be arranged in parallel.

[0049] On the other hand, in the hanging box 2 of the present embodiment as well, it is desirable that the front-side hanging hole 81 and the back-side hanging hole 82 are symmetrically positioned with respect to the fold line 42 between the hanging front portion 21 and the hanging back portion 22. Further, it is desirable that a part of the front-side hanging hole 81 is positioned between the fold line 42 between the hanging front portion 21 and the hanging back portion 22 and the hanging front portion storage fold line 44. When the front-side hanging hole 81 and the back-side hanging hole 82 are in this position, the hanging hole 80 formed thereby is formed at a high position of the hanging portion 20 close to the fold line 42 between the hanging front portion 21 and the hanging back portion 22. Therefore, when hanging and displaying through a hanging rod in the hanging hole 80, the distance between the box main body portion 10 and the hanging rod can be increased, and it becomes easy to take out the product from the hanging rod. When the box main body portion 10 is thin as described above, the ease of taking out is particularly enhanced.

[0050] On the other hand, in the hanging box 2 of the present embodiment, it is desirable that the restoring force of the fold line 41 between the upper edge of the front portion 12 and the hanging front portion 21 is weaker than the restoring force of the folding-back of the hanging front portion storage fold line 44. In the hanging box 2 of the present embodiment, the second insertion piece side is inserted into the slit 51 from the hanging front portion storage fold line 44. Therefore, in the first embodiment, similar to making the restoring force of the fold line 41 between the upper edge of the front portion 12 and the hanging front portion 21 weaker than the restoring force of the fold line 42 between the hanging front portion 21 and the hanging back portion 22, with this configuration, in the stored state, in particular, the portion inserted into the slit 51 comes into contact with the back portion 14 so as to push it and increase the friction. On the other hand, due to the restoring force of the fold line between the upper edge of the front portion 12 and the hanging front portion 21, it becomes difficult for the hanging back portion 22 to come out of the slit 51, and the stored state of the hanging portion 20 is preferably maintained.

[0051] On the other hand, in the hanging box 2 of the present embodiment as well, it is desirable to provide the middle box portion 90 and position and sandwich the portion inserted into the slit 51 between the back plate portion 91 of the middle box portion 90 and the back portion 14. The stored state of the hanging portion 20 is preferably maintained.

[0052] (Sheet material) Next, the sheet material 1S of the present invention related to the suspension boxes 1 and 2 shown in the first and second embodiments will be described. In the case of having the middle box portion 90, the sheet material 1S constituting the box main body portion 10 and the suspension portion 20 and the sheet material constituting the middle box portion 90 may be the same or different.

[0053] The material of the sheet material 1S according to the present invention is not necessarily limited. It may be a resin sheet material such as a plastic sheet, or a sheet material made of a fibrous material such as paper or non-woven fabric. Further, the sheet material may have a single-layer structure or a multi-layer structure. It may be a laminate or the like of a fibrous material such as paper or non-woven fabric and a resin film integrated by lamination. It may be a material with a metal such as aluminum vapor-deposited thereon, or a material with a metal foil laminated and integrated. Specific examples include biodegradable plastic sheets, plastic sheets, non-woven fabric sheets, and foldable sheet materials such as paper.

[0054] A preferred sheet material according to the present invention is paper composed only of fibers derived from natural materials from the viewpoints of depolymerization and plastic reduction, and particularly paper made by papermaking pulp fibers. The paper may be single-layer paper or multi-layer paper with a plurality of paper layers laminated. It may have water resistance and oil resistance. Specific examples include white cardboard, liner base paper (corrugated base paper), coated board paper, coated paper, and kraft paper. Considering the printing appearance, coated paper with an inorganic pigment coated on the surface is preferred, and from the viewpoint of environmental consideration, unbleached or semi-bleached paper is desirable.

[0055] When the sheet material 1S is made of paper formed by papermaking pulp fibers, the constituent pulp fibers of the paper are not necessarily limited, but preferred constituent pulp fibers are softwood kraft pulp such as unbleached softwood kraft pulp (NUKP), semi-bleached softwood kraft pulp (NSBKP), bleached softwood kraft pulp (NBKP), etc., and hardwood kraft pulp such as unbleached hardwood kraft pulp (LUKP), semi-bleached hardwood kraft pulp (LSBKP), bleached hardwood kraft pulp (LBKP), etc. It is desirable that one or more of these pulps are selected. As other pulps, various known pulps such as wastepaper pulp, chemical pulps such as hardwood sulfite pulp and softwood sulfite pulp, or pulps chemically or mechanically produced from non-wood fibers such as kenaf, hemp, and reed can be appropriately combined and used. Since it is easy to exhibit strength, it is desirable that the softwood kraft pulp and the hardwood kraft pulp are 90 to 100% by mass. In this case, the blending ratio of the softwood kraft pulp and the hardwood kraft pulp is preferably 5:95 to 30:70. If a hanging box with a bleached and clean feeling and a hard feeling is to be made, it is particularly preferable to use bleached softwood kraft pulp and bleached hardwood kraft pulp, which are white pulp and have a high whiteness.

[0056] When the sheet material 1S is made of paper, the basis weight can be appropriately adjusted according to the size of the hanging box and the mass of the product contained therein, but preferably it is 180 g / m 2 or more and 460 g / m 2 or less, particularly preferably 250 g / m 2 or more and 360 g / m 2 or less. The paper thickness is preferably 200 μm or more and 1000 μm or less, and preferably 300 μm or more and 900 μm or less. With this basis weight and paper thickness, it is easy to assemble by bending each part, and moreover, it is easy to obtain sufficient rigidity and strength. The basis weight is a value measured in accordance with the "Paper and Paperboard - Basis Weight Measurement Method" described in JIS P 8124 (2011), and the paper thickness is a value measured in accordance with the "Paper and Paperboard - Test Methods for Thickness and Density" described in JIS-P8118 (2014).

[0057] When the sheet material 1S is made of paper, it is desirable to add at least one of a sizing agent and a paper strength enhancer as a papermaking additive. It is easy to adjust to the desired strength. The addition amount of the sizing agent is preferably 0.5 kg / t or more and 5.0 kg / t or less in terms of solid content. The addition amount of the paper strength enhancer is preferably 12 kg / t or more and 30 kg / t or less in terms of solid content. Note that "kg / t" indicates the mass (kg) per 1 t of pulp. By setting the addition amount of the sizing agent within this range, the water resistance and strength are enhanced.

[0058] Examples of the sizing agent include styrene-based sizing agents, alkyl ketene dimer (AKD), alkenyl succinic anhydride (ASA), neutral rosin sizing agents, rosin sizing agents, modified rosin emulsion sizing agents, and the like. Among these, rosin sizing agents and modified rosin emulsion sizing agents are preferred. The rosin sizing agent is not particularly limited. Rosin-based substances include, for example, reinforced rosins obtained by modifying rosins such as gum rosin, wood rosin, and tall oil rosin with α,β-unsaturated carboxylic acids such as fumaric acid, maleic acid, and acrylic acid or their anhydrides, and rosin esters obtained by reacting rosins with polyhydric alcohols such as glycerin, trimethylolethane, trimethylolpropane, pentaerythritol, and diglycerin. In addition, the rosin sizing agent includes those obtained by emulsifying these alone or as a mixture, those obtained by emulsifying them alone and then mixing them, and those obtained by adding various polymers to the emulsified product to further improve the sizing performance.

[0059] As the paper strength enhancer, various known ones such as polyacrylamide resins, polyamide resins, polyamine resins, acrylic resin systems, melamine resins, urea resins, and polyamide epichlorohydrin resins can be used. Among these, it is preferable to use an amphoteric paper strength enhancer. Examples of amphoteric polyacrylamide include copolymers of acrylamide and anionic monomers and cationic monomers, Mannich-modified products of copolymers of acrylamide and anionic monomers, Hofmann degradation products, and the like. In particular, since amphoteric polyacrylamide has a self-fixing function, even if it is added to improve the inter-paper strength, it will not become cation-excessive, and it can be stably fixed by including it together with a modified rosin emulsion sizing agent.

[0060] Also, when the sheet material 1S is made of paper, various additives other than the sizing agent and the paper strength enhancer can be contained within a range that does not impair the intended effects of the present invention. For example, polyvinyl alcohol, wax, etc. can be applied. In particular, it is desirable that a polyvinyl alcohol-based resin such as polyvinyl alcohol and a styrene-acrylic copolymer resin emulsion are externally applied. Furthermore, it is desirable that paraffin wax is externally applied. By these external applications, in particular, the oil resistance is improved.

[0061] Furthermore, when the sheet material 1S is made of paper, a siloxane compound may be contained. When a siloxane compound is contained, the stiffness, strength, and water resistance are increased by the siloxane bond. The siloxane compound may be added to the suspended box after assembly, or may be contained by impregnating the sheet material before assembly with an appropriate alkoxysilane solution or a processed product of an alkoxysilane solution and then heating. In this way, it is desirable because the siloxane compound is contained in a manner of binding to the pulp fibers themselves or coating the pulp fibers.

[0062] Furthermore, when the sheet material 1S is paper, a pigment coating layer may be provided on one or both sides. By providing the pigment coating layer, printability and aesthetics (cosmetic properties) are particularly improved. The pigment used in the pigment coating layer is not necessarily limited. Known materials such as calcium carbonate, kaolin, and plastic pigments can be used. As the binder, known materials such as styrene-butadiene latex, oxidized starch, various modified starches, and polyvinyl alcohol can be used. When providing the pigment coating layer, the coating amount is preferably 8 g / m 2 ~20 g / m 2 . If it is less than 8 g / m 2 , the printability may not be sufficiently improved. If it exceeds 20 g / m 2 , problems such as cracking of the coating layer and powder falling may occur when folding. When providing the pigment coating layer, the pigment coating method is not limited. Known coating methods such as roll coating, rod coating, blade coating, air knife coating, and curtain coating can be used.

[0063] In the hanging box 1 of the present invention, when the sheet material 1S is paper, as described above, the paper layer may be single-layer or multi-layer, but particularly preferred paper is multi-layer paper having three or more paper layers. Of course, even when using multi-layer paper, additives such as papermaking additives used in the above paper can be added or a pigment coating layer can be provided. When using multi-layer paper, particularly high-density multi-layer paper is desirable. The density is 0.65~1.15 g / cm 3 , particularly 0.80~1.00 g / cm 3is preferable. When the density of the multi-layer paper is within this range, it becomes difficult to fold while having excellent rigidity at a high basis weight. Here, although it is difficult to increase the strength of a single-layer paper material compared to a plastic material, it is easy to increase the strength of multi-layer paper. As shown in FIG. 14, since the multi-layer paper 100 has a plurality of paper layers laminated, the characteristics of each layer can be changed, and it can be easily bent while having strength. For example, by combining a pair of surface layers 101 that are hard but tend to be easily broken although excellent in water resistance and abrasion resistance with a flexible middle layer 102, it becomes excellent in toughness and durability, and can be bent while having strength, and can be easily assembled. Further, when each fold line is a half slit, it is easy to form a portion where a plurality of layers including the surface layer are not completely cut, and the risk of breakage at each fold line is significantly reduced, and it can have a deflection. The multi-layer paper 100 can be manufactured by multi-layer papermaking. Further, the multi-layer paper 100 may be a commercially available product. For example, Elipra Paper, Elipra Plus manufactured by Dainippon Paper Industries Co., Ltd., N Pearl Deluxe, S Pearl Card, S Mitsubishi Waterproof manufactured by Mitsubishi Paper Mills Limited, etc. can be exemplified.

[0064] When the sheet material 1S is the multi-layer paper 100, the number of its layers is not limited, but it is preferably three to nine layers, and the number of layers of the middle layer 102 is preferably three or more layers, particularly five layers. In particular, the form shown in FIG. 14 has three layers of the middle layer 102. When the total number of the middle layers 102 is three or more, it is said that the toughness and durability of the multi-layer paper 100 are more likely to be exhibited. From the viewpoint of maintaining the interlayer strength, the upper limit of the total number of the middle layers 92 is preferably seven layers or less. Further, three to seven layers are easy to operate while maintaining the interlayer strength in the case of using a cylinder multi-cylinder papermaking machine.

[0065] Further, when the sheet material 1S is the multi-layer paper 100, the basis weight of each layer is not limited, but preferably, as the basis weight of the surface layer 101, it is 10.0 g / m per layer 2 or more and 70.0 g / m 2 or less, particularly preferably 25 to 55 g / m 2 is. Further, as the basis weight of the entire middle layer 102, preferably, it is 140 g / m 2 or more and 340 g / m2 Specifically, it is preferably 200 g / m 2 or more and 300 g / m 2 or less. Further, the ratio of the total basis weight of the surface layers 101 and 101 to the basis weight of the entire multi-layer paper is preferably 15.0% or more and 35.0% or less. In this way, the surface layer has high rigidity and the middle layer has excellent flexibility. Also, in the multi-layer paper, by setting the ratio of the total basis weight of the surface layer within the above range, it is possible to impart the property of being difficult to bend.

[0066] Also, when the sheet material 1S is the multi-layer paper 100, it is desirable that the pulp fibers constituting each layer are a mixture of softwood kraft pulp and hardwood kraft pulp for the pulp of the surface layer 101 and the middle layer 102. The paper thickness becomes thick and it is easy to ensure sufficient strength. Also, the mass ratio of the softwood kraft pulp to the hardwood kraft pulp in the surface layer (softwood kraft pulp / hardwood kraft pulp) is desirably 0 / 100 to 40 / 60 or less. A large amount of hardwood kraft pulp, which is rigid and easy to densify, is contained, and the surface layer tends to have high density and rigid characteristics and excellent strength. Along with such a surface layer, for the middle layer, it is desirable to increase the ratio of softwood kraft pulp compared to the surface layer. In this case, it is desirable to adjust the mass ratio of the softwood kraft pulp to the hardwood kraft pulp in the middle layer (softwood kraft pulp / hardwood kraft pulp) to 20 / 80 to 40 / 60 or less. This results in a large amount of softwood kraft pulp rich in flexibility, and the middle layer has good flexibility. With this ratio, the surface layer has high density and rigid characteristics, and the middle layer is more flexible than the surface layer, and the strength is less likely to decrease even with bending at each fold line during assembly and repeated bending.

[0067] Also, when the sheet material 1S is a multi-layer paper 100, it is preferable to add at least one of the above sizing agent and paper strength enhancer as a papermaking additive to each of the surface layers 101, 101 and the middle layer 102. In this case, as the addition amount of the sizing agent for the surface layer, 0.5 kg / t or more and 5.0 kg / t or less in terms of solid content is preferable. Also, as the addition amount of the sizing agent for the middle layer, 2.0 kg / t or more and 5.0 kg / t or less in terms of solid content is preferable. Further, as the addition amount of the paper strength enhancer for each layer, 12 kg / t or more and 30 kg / t or less in terms of solid content is preferable. By setting it within this range, it is easy to impart various paper strengths such as the interlayer strength of the multi-layer paper.

[0068] Furthermore, regardless of whether the material of this sheet material 1S is paper, the Z-axis strength measured in accordance with JAPAN TAPPI Paper Pulp Test Method No. 18-2:2000 is preferably 400 kN / m 2 or more. In this hanging box, the hanging part has a shape that can be pulled up, and it has a shape that can be formed by punching such as Thomson processing or cutting by a cutting plotter. With the above Z-axis strength, such punching and cutting can be easily performed, making it easy to manufacture.

[0069] When this sheet material 1S is paper, the coefficient of static friction according to JIS P 8147 ISO horizontal method is preferably 0.15 to 0.65. It is easy to keep the hanging part in a stored state and also easy to smoothly pull it up. In this measurement method, it is desirable to perform three measurements each for the back surfaces of the sheet materials and the front surfaces, and the measured values of the third measurement for both the back surfaces and the front surfaces are within the above range. For the ISO horizontal method, it is sufficient to measure at least one of the coefficient of static friction of the first slip, the coefficient of static friction of the third slip, or the coefficient of kinetic friction of the third slip. The coefficient of static friction of the third slip tends to be smaller than the coefficient of static friction of the first slip, and the variation of the coefficient of static friction of the third slip is smaller.

[0070] Furthermore, when the sheet material 1S is paper, the paper preferably has a PPS (Parker Print Surface Finish) conforming to JIS P 8151 of 1 to 8 μm, more preferably 4 to 7 μm, on both the front and back surfaces. This improves printing suitability, makes it easier to maintain the hanging part in a stored state, and also makes it easier to smoothly pull up.

[0071] Furthermore, when the sheet material 1S is paper, it is desirable that the paper has a tensile strength in the longitudinal direction measured in accordance with JIS P 8113 (2006) of 20 kN / m or more and a tensile strength in the transverse direction of 5 kN / m or more. Having this tensile strength makes it suitable for folding and assembly.

[0072] Also, in the case where the sheet material 1S is paper, the paper can have a Taber stiffness measured in accordance with JIS P 8125 (2000) of 50 mN·m or more in the longitudinal direction and 5 mN·m or more in the transverse direction. Also, the folding endurance measured in accordance with JIS P 8115 (2001) can be 1.3 or more in the longitudinal direction and 1.3 or more in the transverse direction. Within this range, folding and assembly are easy.

[0073] Furthermore, the hanging boxes 1 and 2 according to the present embodiment may be coated or impregnated with a surface protection agent, an antibacterial agent, or an antiviral agent without excessively changing the friction coefficient, surface roughness, or folding suitability and without interfering with the effects of the present invention.
