Description

[Technical Field]

[0001] This invention relates to a hanger. [Background technology]

[0002] Hard plastic hangers are widely used for displaying and selling clothing such as jackets, trousers, and underwear, as well as for mail-order sales and for storing clothing in dry cleaners and homes. In addition, hotels and inns sometimes provide hard plastic or wooden hangers in the closets of guest rooms for use (see Patent Documents 1 and 2 below).

[0003] Because hangers made from rigid plastic are formed by creating a mold and injection molding, many of them are thick and have a structure that makes them difficult to fold or disassemble, resulting in problems with storage and transportation.

[0004] On the other hand, in recent years, issues such as marine pollution caused by microplastics have attracted attention, and the global movement towards de-plasticization is progressing from an environmental protection standpoint. In Japan, the "Act on Promotion of Resource Recycling Related to Plastics" has been enacted, which, for example, mandates that certain businesses reduce the use of single-use plastic products. Furthermore, this "Act on Promotion of Resource Recycling Related to Plastics" designates plastic hangers as "specific plastic products," and there is a growing demand for de-plasticization of hangers.

[0005] Here, a technology for replacing plastic hangers with paper ones has been proposed, for example, in Patent Documents 3, 4, and 5 listed below.

[0006] The hanger disclosed in Patent Document 3 has a hook portion and a hanger portion that are separate, allowing it to be disassembled into sheet-like parts. Although made of paper, it is easier to store and transport than plastic hangers in which the hook portion and hanger portion are integrally molded.

[0007] The hangers disclosed in Patent Documents 4 and 5 are made by folding and assembling a single sheet material to form a three-dimensional shape, which makes it less likely for clothes to wrinkle or lose their shape when in use. [Prior art documents] [Patent Documents]

[0008] [Patent Document 1] Patent No. 6954700 [Patent Document 2] Patent No. 6694198 [Patent Document 3] Japanese Patent Publication No. 2011-182807 [Patent Document 4] Utility Model Registration No. 3159829 [Patent Document 5] Japanese Patent Publication No. 2019-151364 [Overview of the project] [Problems that the invention aims to solve]

[0009] However, while the hangers described in Patent Documents 3 to 5, which are made of sheet materials such as paper, offer excellent storage and transportability in their unassembled sheet state, they have the problem of being difficult to return to their sheet shape after assembly, and being bulky when discarded, restoring, or re-transporting. In particular, the hanger described in Patent Document 3 requires the complicated operation of assembling and disassembling multiple components when in use or transporting.

[0010] On the other hand, in dry cleaning shops, stores and warehouses of companies that display and sell clothing and other items via mail order, and accommodation facilities, the operation of hanging and removing clothes from hangers onto hanger bars or hanger racks is often repeated. In particular, in the work of dry cleaning shops, stores and warehouses, a large amount of clothing is handled, so quick operation is often required. In such operations, twisting and bending are especially likely to be applied to the hook part. Paper materials tend to be less strong than plastic materials. The hangers in Reference Documents 3 and 4 have a hook part that is made only of two sheets layered together, so the strength of the hook part may be insufficient and break when performing such repeated operations or quick hanging and removing operations. The hanger in Patent Document 5 has a hook part that is reinforced by a hook part reinforcing piece and is made up of four sheets in total, and the hook part is formed three-dimensionally by a locking piece, which increases the strength of the hook, but because the four sheets are not completely laminated by the locking piece, the strength against twisting and the like may not be sufficient.

[0011] On the other hand, in stores and warehouses of companies that sell or display clothing, especially dry cleaners, disposable dress covers 200 made of polyethylene, polypropylene, or other resins or nonwoven fabrics are sometimes used to prevent dust and dirt from adhering to clothing 150 hung on hangers 100, as shown in Figure 14. Dress covers are also called garment covers, dress packs, hanger covers, vinyl covers, etc. The dress cover 200 is cylindrical in shape with a wide opening 210 on one end and a narrow opening 220 on the other, and is used by passing the hook portion 103 of the hanger 100 through the narrow opening. As shown in Figure 15, especially disposable dress covers 200 are usually made by fusing the edges 200E of polyethylene or polypropylene sheets, nonwoven fabric sheets, or resin sheets and nonwoven fabric sheets together, and typically do not have gussets. Therefore, if the hook portion is made three-dimensional and thick using a locking piece, as in the hanger in reference 5, there is a high risk that the edge 220t of the narrow opening 220 of the dress cover 200 will tear or rip, making it difficult to use.

[0012] Furthermore, the hanger described in Patent Document 5 has a valley fold portion and a mountain fold portion on one side of the sheet material before assembly, and the manufacturing process is complicated because it is necessary to form fold lines etc. from both sides of the sheet material. In addition, because the structure is such that two large cardboard hanging portions are connected by a short bend line between the hook-forming pieces, there is a risk that the bend line may break and the cardboard hanging portions may unintentionally separate.

[0013] Thus, conventional paper hangers, such as those disclosed in Patent Documents 3 to 5, have advantages over integrally molded plastic hangers in terms of storage and transportability because they are made of thin, sheet-like paper before assembly. However, they have problems such as being difficult to return to a sheet shape after assembly, making disposal and re-storage difficult; the strength of the hook portion may not be sufficient in light of actual usage in places such as dry cleaners, stores and warehouses of companies that display and sell clothing and other items via mail order, and accommodation facilities; and there is a risk of tearing when using disposable dress covers.

[0014] Therefore, in view of the above problems, the main object of the present invention is to provide a hanger that has a three-dimensional usage form during use, can be easily returned to a sheet shape, has excellent strength of the hook portion, and is difficult to break the opening of the dress cover even when the dress cover is used, and can be easily manufactured from a non-plastic sheet material.

Means for Solving the Problems

[0015] The first means for solving the above problems is a hanger for clothes, having a hanger main body portion for hanging clothes and a hook portion for hanging on a support, the hanger main body portion is composed of a first frame main body portion and a second frame main body portion, the hook portion is composed of a first hook portion forming piece and a first hook portion reinforcing piece and a second hook portion forming piece and a second hook portion reinforcing piece, the first frame main body portion, the second frame main body portion, the first hook portion forming piece, the first hook portion reinforcing piece, the second hook portion forming piece, and the second hook portion reinforcing piece are composed of a single sheet material, the first frame main body portion has a first top portion, a first right shoulder portion and a first left shoulder portion extending obliquely outward in the left and right directions from the first top portion, a first bottom portion connecting the lower portions of the first right shoulder portion and the first left shoulder portion, a first shoulder upper portion forming piece extending from the first right shoulder portion and the first left shoulder portion through a first shoulder fold line and widening from the first top portion side toward the first bottom portion side, and an insertion piece extending from the first shoulder upper portion forming piece through an insertion piece forming fold line, the second frame main body portion has a second top portion, a second right shoulder portion and a second left shoulder portion extending obliquely outward in the left and right directions from the second top portion, a second bottom portion connecting the lower portions of the second right shoulder portion and the second left shoulder portion, a second shoulder upper portion forming piece extending from the second right shoulder portion and the second left shoulder portion through a second shoulder fold line, It has insertion parts that are located between the second right shoulder portion and the second left shoulder portion and the upper forming piece of the second shoulder portion, into which an insertion piece can be inserted. The first hook-forming piece is, Extending from the first peak, The first hook section reinforcing piece is, It connects to the first hook-forming piece via the first hook-part fold line, and by folding back along the first hook-part fold line, it overlaps with part or all of the first hook-forming piece. The second hook-forming piece is, Extending from the second peak, The reinforcing piece for the second hook section is, It connects to the second hook-forming piece via the second hook-part fold line, and by folding it back along the second hook-part fold line, it overlaps with part or all of the second hook-forming piece. The first frame body and the second frame body are connected by a common bottom fold line between the bottom edge of the first bottom and the bottom edge of the second bottom, and by folding along this bottom fold line, the first vertex and the second vertex are positioned opposite each other in a butt joint. Furthermore, by folding along the first shoulder fold line, the second shoulder fold line, and the insertion piece forming fold line, the insertion piece becomes insertable into the insertion section at the opposite position. This hanger has the following characteristics:

[0016] The second method is, The first hook-forming piece has a first locking groove at its tip, The first hook portion reinforcing piece overlaps with the first hook portion forming piece in the area excluding the tip when folded along the first hook portion fold line. The first hook-forming piece has a first locking groove at its tip, The first hook portion reinforcing piece overlaps with the first hook portion forming piece in the area excluding the tip when folded along the first hook portion fold line. When the first and second vertices are in a butt-to-butt-to-face position, the first locking groove and the second locking groove become able to lock together. This is a hanger related to the first method described above.

[0017] The third option is, Fold the first hook reinforcing piece back along the first hook fold line and overlap it with the first hook forming piece. Fold the reinforcing piece of the second hook portion back along the fold line of the second hook portion and overlap it with the forming piece of the second hook portion. By folding the first frame body and the second frame body along the bottom fold line, the first apex and the second apex, along with the first hook reinforcement piece and the second hook reinforcement piece, come into a butt-joint position. When inserting the insertion piece into the insertion part at that opposite position, A hook portion is formed by laminating four layers of sheet material using a first hook portion forming piece, a first hook portion reinforcing piece, a second hook portion forming piece, and a second hook portion reinforcing piece. This is a hanger related to the first method described above.

[0018] The fourth method is, The first hook fold line, the second hook fold line, the first shoulder fold line, the second shoulder fold line, and the insertion piece forming fold line are half-slits and are formed on the same surface. This is a hanger related to the first method described above.

[0019] The fifth method is, The sheet material is paper made from pulp fibers, and that paper is a multilayer paper in which multiple layers of paper are laminated together. This is a hanger related to the first method described above. [Effects of the Invention]

[0020] According to the present invention, a hanger is provided that has a three-dimensional form for use, is easy to return to a sheet form, has excellent strength in the hook portion, has a structure that prevents the opening of the dress cover from tearing even when a dress cover is used, and can be easily manufactured from a non-plastic sheet material.

[0022] Next, embodiments of the present invention will be described in detail below with reference to Figures 1 to 15. However, the present invention is not limited to the shapes shown or these embodiments. It goes without saying that the detailed shapes and positions of each part can be changed within the scope of the present invention.

[0023] The hanger 1 according to this embodiment is a hanger for clothes, and as shown in Figure 1, in its usage configuration, it has a roughly triangular hanger body 2 for hanging clothes and a hook portion 3 having a sickle-shaped hook portion 3F for hanging on a support.

[0024] The hanger body 2 is configured such that the first frame body 20A and the second frame body 20B face each other, and the hook portion 3 is configured such that the first hook portion forming piece 30A, the first hook portion reinforcing piece 33A, the second hook portion forming piece 30B, and the second hook portion reinforcing piece 33B overlap, resulting in an overall three-dimensional shape.

[0025] In this hanger 1, the first frame body portion 20A, the second frame body portion 20B, the first hook portion forming piece 30A, the first hook portion reinforcing piece 33A, the second hook portion forming piece 30B, and the second hook portion reinforcing piece 33B are all thin plates, and are particularly unfolded into a single flexible sheet material as shown in Figures 2 and 3.

[0026] In this deployed state, the first frame body 20A has a first apex 21, a first right shoulder 22R and a first left shoulder 22L extending diagonally outward from the first apex 21, and a first bottom 23 connecting the lower parts of the first right shoulder 22R and the first left shoulder 22L. In particular, in the illustrated form, it has a first opening 24 surrounded by the first apex 21, the first right shoulder 22R, the first left shoulder 22L, and the first bottom 23, and the first frame body 20A and the first opening 24 as a whole form a roughly isosceles triangle. However, the shape of the first opening 24 is not limited to this shape.

[0027] The second frame body 20B has a second apex 25, a second right shoulder 26R and a second left shoulder 26L extending diagonally outward from the second apex 25, and a second bottom 27 connecting the lower parts of the second right shoulder 26R and the second left shoulder 26L. In particular, in the illustrated form, it has a second opening 28 surrounded by the second apex 25, the second right shoulder 26R, the second left shoulder 26L, and the second bottom 27, and the second frame body 20B and the second opening 28 as a whole have a roughly isosceles triangular shape. However, the shape of the second opening 28 is not limited to this shape.

[0028] The first frame body 20A and the second frame body 20B are connected as a single unit by a common straight bottom fold line 51, which is the bottom edge 23E of the first bottom 23 and the bottom edge 27E of the second bottom 27. When the first frame body 20A or the second frame body 20B is folded back along the bottom fold line 51, the first vertex 21 and the second vertex 25 are positioned opposite each other in a butt joint. The illustrated form is a particularly preferred form in which the first vertex 21 and the second vertex 25, the first right shoulder 22R and the second right shoulder 26R, the first left shoulder 22L and the second left shoulder 26L, the first bottom 23 and the second bottom 27, and the first opening 24 and the second opening 28 are positioned symmetrically with respect to the bottom fold line 51 and overlap when folded back.

[0029] On the other hand, in the hanger 1 of this embodiment, the first hook portion forming piece 30A extends from the first top portion 21 in the direction opposite to the first bottom portion, and as shown in Figures 2 and 4, the first hook portion 31F is configured to protrude above the first top portion 21. Furthermore, the tip portion 31t of the first hook portion forming piece 30A is provided with a first locking groove 31m that is cut out in a roughly V shape.

[0030] Furthermore, in the hanger 1 of this embodiment, the second hook portion forming piece 30B extends from the second top portion 25 in the direction opposite to the second bottom portion, and as shown in Figures 2 and 4, the second hook portion 32F is configured to protrude above the second top portion 25. In addition, the tip portion 32t of the second hook portion forming piece 30B is provided with a second locking groove 32m that is cut out in a roughly V shape.

[0031] In the illustrated configuration, the first hook-forming piece 30A and the second hook-forming piece 30B are identical in shape except for the tip, and are substantially symmetrical with respect to the bottom fold line 51. They are configured to face each other and overlap when the bottom fold line 51 is folded back, and the first locking groove 31m and the second locking groove 32m can lock into each other at the overlapping position. Note that the first hook-forming piece 30A and the second hook-forming piece 30B do not need to be completely identical in shape in parts other than the tip, but it is desirable that they be identical in shape.

[0032] On the other hand, in the hanger 1 of this embodiment, the first hook portion reinforcing piece 33A is connected to the first hook portion forming piece 30A via the first hook portion fold line 55, and is configured to overlap part or all of the first hook portion forming piece 30A by folding back along the first hook portion fold line 55. In the illustrated form, a preferred shape is that which is substantially the same as the area of ​​the first hook portion forming piece 30A excluding the tip portion 31t, and is substantially symmetrical with respect to the area of ​​the first hook portion forming piece 30A excluding the tip portion 31t, with respect to the first hook portion fold line 55 as the axis of symmetry. However, the shape of the first hook portion reinforcing piece 33A is not necessarily limited. For example, if the first locking groove 31m is not formed on the tip portion 31t of the first hook portion forming piece 30A, the shape may include the first hook portion forming piece 30A and the tip portion 31t.

[0033] The connection position between the first hook-forming piece 30A and the first hook-reinforcement piece 33A is not necessarily limited. It is acceptable as long as it is a position that allows them to form a single sheet when unfolded. However, it is desirable that this connection portion be long so that it is difficult for the sheet to separate unintentionally. In the illustrated form, the first hook-forming piece 30A is formed in a straight line from the first apex 21 side to the sickle-shaped outer circumference end of the first hook-forming piece 30A, and this straight section is configured to be connected as the first hook-fold line 55.

[0034] On the other hand, the second hook portion reinforcing piece 33B in the hanger 1 of this embodiment is connected to the second hook portion forming piece 30B via the second hook portion fold line 56, and is configured to overlap part or all of the second hook portion forming piece 30B by folding back along the second hook portion fold line 56. In the illustrated form, a preferred shape is that which is substantially the same as the area of ​​the second hook portion forming piece 30B excluding the tip portion 32t, and is substantially symmetrical with respect to the area of ​​the second hook portion forming piece 30B excluding the tip portion 32t, with respect to the second hook portion fold line 56 as the axis of symmetry. However, the shape of the second hook portion reinforcing piece 33B is not necessarily limited. For example, if the second locking groove 32m is not formed on the tip portion 32t of the second hook portion forming piece 30B, the shape may include the tip portion 32t of the second hook portion forming piece 30B.

[0035] The connection position between the second hook-forming piece 30B and the second hook-reinforcement piece 33B is not necessarily limited. It is acceptable as long as it is a position that allows it to form a single sheet when unfolded. However, it is desirable that this connection portion be long so that it is difficult to unintentionally separate when it is in sheet form. In the illustrated form, the second hook-forming piece 30B is formed in a straight line from the second apex 25 side to the sickle-shaped outer edge of the second hook-forming piece 30B, and this straight section is configured to connect as the second hook-fold line 56. In the illustrated form, the second hook-reinforcement piece 33B and the first hook-reinforcement piece 33A are substantially the same shape and are substantially symmetrical with respect to the bottom fold line 51 as the axis of symmetry, but it is not necessarily required to form them in this way.

[0036] In the hanger 1 of this embodiment, starting from the unfolded state shown in Figure 2, the first hook portion reinforcing piece 33A is folded back along the first hook portion fold line 55 shown in Figure 4 so that it overlaps with the first hook portion forming piece 30A, and the second hook portion reinforcing piece 33B is folded back along the second hook portion fold line 56 so that it overlaps with the second hook portion forming piece 30B. With the first hook portion reinforcing piece 33A and the second hook portion reinforcing piece 33B facing each other, the first frame body 20A or the second frame body 20B is folded back along the bottom fold line 51, as shown in Figures 1, 5 to 7. This results in a first hook portion 31F protruding upward from the first top portion 21 where the first hook portion forming piece 30A and the first hook portion reinforcing piece 33A are stacked, and a second hook portion 32F protruding upward from the second top portion 25 where the second hook portion forming piece 30B and the second hook portion reinforcing piece 33B are stacked, overlapping and facing each other, forming a hook portion 3 with quadruple layers of sheet material that is strong against twisting and torsion. Furthermore, in this illustrated configuration, as shown in Figures 5 and 6, the first hook portion reinforcing piece 33A does not overlap the tip portion 31t of the first hook portion forming piece 30A, and the second hook portion reinforcing piece 33B does not overlap the tip portion 32t of the second hook portion forming piece 30B. Therefore, the first hook portion reinforcing piece 33A and the second hook portion reinforcing piece 33B are not positioned between the tip portion 31t of the first hook portion forming piece 30A and the tip portion 32t of the second hook portion forming piece 30B. As a result, the first locking groove 31m formed on the tip portion 31t of the first hook portion forming piece 30A and the second locking groove 32m formed on the tip portion 32t of the second hook portion forming piece 30B face each other, enabling locking. As shown in Figures 10 to 12, by engaging the first locking groove 31m and the second locking groove 32m, the first hook-forming piece 30A, the first hook-reinforcement piece 33A, the second hook-forming piece 30B, and the second hook-reinforcement piece 33B are laminated and integrated with extremely simple operation. Furthermore, the integration of the first hook-forming piece 30A, the first hook-reinforcement piece 33A, the second hook-forming piece 30B, and the second hook-reinforcement piece 33B is released simply by releasing this engagement. Note that the means for laminating and integrating the first hook-forming piece 30A, the first hook-reinforcement piece 33A, the second hook-forming piece 30B, and the second hook-reinforcement piece 33B may be other than the engagement between the first locking groove 31m and the second locking groove 32m, for example, by adhesive, adhesive tape, clips, etc.However, as described above, since integration and release can be easily performed, a configuration in which the first locking groove 31m and the second locking groove 32m are engaged is preferable.

[0037] On the other hand, the first frame body portion 20A of the hanger 1 in this embodiment has a first shoulder upper forming piece 41 that extends from the first right shoulder portion 22R and the first left shoulder portion 22L via a first shoulder fold line 52 and widens from the first top portion 21 side to the first bottom portion 23 side, and an insertion piece 42 that extends from the first shoulder upper forming piece 41 via an insertion piece forming fold line 53. In the illustrated form, the first shoulder upper forming piece 41 is a roughly triangular shape with a tapered top side, but is not necessarily limited to this. It may be roughly trapezoidal. Also, there may be multiple first shoulder upper forming pieces 41. Furthermore, in the illustrated form, the insertion piece 42 is a roughly rectangular shape with a rounded tip, but is not limited to this. It may be formed with a tapered tip. Also, in the illustrated form, one insertion piece 42 is formed on one first shoulder upper forming piece 41, but multiple insertion pieces 42 may be formed on one first shoulder upper forming piece 41.

[0038] The second frame body portion 20B has a second shoulder upper forming piece 43 that extends from the second right shoulder portion 26R and the second left shoulder portion 26L via the second shoulder fold line 54, and an insertion portion 44 that is located between the second right shoulder portion 26R and the second left shoulder portion 26L and the second shoulder upper forming piece 43, into which an insertion piece 42 can be inserted.

[0039] In the illustrated configuration, the second shoulder upper forming piece 43 in the second frame body 20B is roughly triangular in shape, widening from the second apex 25 side to the second bottom 27 side, similar to the first shoulder upper forming piece 41, but is not necessarily limited to this shape. The second shoulder upper forming piece 43 only needs to function as an excess portion for forming an insertion portion 44 between at least the second right shoulder 26R and the second left shoulder 26L. However, it is desirable to have a shape that overlaps with the first shoulder upper forming piece 41 in a plan view during assembly, and preferably a similar shape that is slightly smaller than the first shoulder upper forming piece 41.

[0040] The insertion portion 44 only needs to be shaped so that the insertion piece 42 formed on the first frame body portion 20A can be inserted into it. Preferably, the width of the insertion portion 44 is the same as the width of the insertion piece 42, i.e., the length of the insertion piece forming fold line 53, which is the connection length between the insertion piece 42 and the first shoulder upper forming piece 41. This allows the insertion piece 42 to be inserted into the insertion portion 44 all the way to the base. In the illustrated form, the insertion portion 44 is formed by a slit that penetrates the sheet material. As shown in Figures 7 and 8, when the second shoulder upper forming piece 43 is folded back, the slit opens, forming an insertion portion 44 which becomes a hole. However, the insertion portion 44 is not limited to a slit. It may also be a long, narrow through-hole formed by punching or cutting. In the illustrated form, one insertion portion 44 is formed for each shoulder portion 26R, 26L, but the number of insertion portions 44 may be multiple depending on the number of insertion pieces 42, etc.

[0041] In the hanger 1 of this embodiment, as shown in Figure 9, the insertion piece 42 and insertion part 44 are configured such that when the first frame body 20A or the second frame body 20B is folded back along the bottom fold line 51, and the first apex 21 and the second apex 25 are in a butt-to-butt-to-face position, and the first shoulder fold line 52, the second shoulder fold line 54 and the insertion piece forming fold line 53 are bent, the insertion piece 42 can be inserted into the insertion part 44.

[0042] In the illustrated configuration, when the first frame body portion 20A and the second frame body portion 20B are folded back along the bottom fold line 51, the first shoulder upper forming piece 41 and the second shoulder upper forming piece 43 extending from each shoulder portion are formed in a position where they are in close proximity to each other. When the first shoulder fold line 52, the second shoulder fold line 54, and the insertion piece forming fold line 53 are folded at this position where they are in close proximity to each other, the insertion piece 42 can be inserted into the insertion portion 44. Then, by inserting the insertion piece 42 into the insertion part 44, as shown in Figures 10 to 12, the second shoulder upper forming piece 43 and the first shoulder upper forming piece 41 overlap, and the first shoulder upper forming piece 41 is bridged between the first right shoulder 22R and the second right shoulder 26R, and between the first left shoulder 22L and the second left shoulder 26L. The first frame main body 20A and the second frame main body 20B, which are facing each other when folded back along the bottom fold line 51, are connected between the first right shoulder 22R and the second right shoulder 26R, and between the first left shoulder 22L and the second left shoulder 26L. The shape of the second shoulder upper forming piece 43 is such that it can overlap within the range of the first shoulder upper forming piece 41 when the first shoulder upper forming piece 41 is bridged. In this embodiment of the hanger 1, the order in which the bottom fold line 51, the first shoulder fold line 52, the second shoulder fold line 54, and the insert piece forming fold line 53 are folded during assembly is not limited.

[0043] In this embodiment of the hanger 1, the first shoulder upper forming piece 41 has a shape that gradually widens from the first top 21 side to the first bottom 23 side, and in the preferred illustrated form, it is approximately triangular in shape. Therefore, when the insertion piece 42 is inserted into the insertion part 44, and the first shoulder upper forming piece 41 is bridged between the first right shoulder 22R and the second right shoulder 26R, and between the first left shoulder 22L and the second left shoulder 26L, the first frame body 20A and the second frame body 20B, which are facing each other, are formed into a three-dimensional shape in which the distance between the first right shoulder 22R and the second right shoulder 26R and the first left shoulder 22L and the second left shoulder 26L gradually widens from the top side to the bottom side, up to the bottom side position of the first shoulder upper forming piece 41. Furthermore, the first frame body 20A and the second frame body 20B can be separated simply by pulling out the insertion piece 42 from the insertion part 44.

[0044] Furthermore, in the hanger 1 of this embodiment, the first shoulder upper forming piece 41 has a shape that gradually widens from the first apex 21 side toward the first bottom 23 side. By adjusting the width on the first apex 21 side according to the thickness of the sheet material, the first apex 21 and the second apex 25 are positioned close together, and the first hook forming piece 30A, the first hook reinforcing piece 33A, the second hook forming piece 30B, and the second hook reinforcing piece 33B, which constitute the hook part 3, can be laminated without gaps or with almost no gaps. The hook part 3 formed by laminating the first hook forming piece 30A, the first hook reinforcing piece 33A, the second hook forming piece 30B, and the second hook reinforcing piece 33B without gaps or with almost no gaps has increased strength against twisting and torsion, as described above. Moreover, because there is no excessive thickness near the first apex 21 and the second apex 25 of the hook part 3, even if a disposable dress cover is used, the opening of the dress cover is less likely to tear.

[0045] On the other hand, in this assembled state, in the hanger 1 of this embodiment, the distance between the first right shoulder portion 22R and the second right shoulder portion 26R and the first left shoulder portion 22L and the second left shoulder portion 26L gradually widens from the top side to the bottom side up to the bottom side position of the first shoulder portion upper forming piece 41. Meanwhile, since the first frame body portion 20A and the second frame body portion 20B are connected by the bottom side fold line 51, in particular when the length from the bottom side position of the first shoulder portion upper forming piece 41 to the bottom side fold line 51 is short or when the widening width of the bottom side of the first shoulder portion upper forming piece 41 is wide, the distance between the first frame body portion 20A and the second frame body portion 20B between the bottom side position of the first shoulder portion upper forming piece 41 and the bottom side fold line 51 becomes rapidly shorter during assembly. For this reason, especially when the sheet material is a stiff material that does not easily bend, it is desirable to provide a first bending guideline 57 and a second bending guideline 58 at the bottom position of the first shoulder upper forming piece 41 or a position closer to the bottom fold line 51 than that position, and at the bottom position of the second shoulder upper forming piece 43 or a position closer to the bottom fold line 51 than that position, to facilitate bending parallel to the bottom fold line 51. In the illustrated form, the bottom position of the first shoulder upper forming piece 41 is located between the first right shoulder 22R, the first left shoulder 22L, and the first bottom 23, and the first bending guideline 57 is provided at this position. The bottom position of the second shoulder upper forming piece 43 is located between the second right shoulder 26R, the second left shoulder 26L, and the second bottom 27, and the second bending guideline 58 is provided at this position. When the first bending guide line 57 and the second bending guide line 58 are provided, the bending of the sheet material is eliminated by these bending guide lines, making assembly easier even with a stiff material, and providing excellent shape retention, reducing the risk of damage or unintended disassembly after assembly.

[0046] In this embodiment, the bottom fold line 51, the first hook fold line 55, the second hook fold line 56, the first shoulder fold line 52, the second shoulder fold line 54, the insert piece forming fold line 53, and the first and second bending guide lines 57 and 58 in the hanger 1 are lines that facilitate folding and bending of the sheet material. They may be simple printed lines for positioning, but are preferably crease lines, perforations, or half-slits. Particularly preferred are half-slits that facilitate bending even with stiff materials. The cut tie ratio when using perforations and the slit depth when using half-slits can be changed depending on the thickness and strength of the sheet material. Furthermore, the first hook fold line 55, the second hook fold line 56, the first shoulder fold line 52, the second shoulder fold line 54, the insert piece forming fold line 53, the first bending guide line 57, and the second bending guide line 58 in the hanger of this embodiment do not all need to be of the same type. For example, the bottom fold line 51 may be a perforation, and the others may be half-slits. Also, the cut tie ratio when using perforations and the slit depth when using half-slits do not need to be the same.

[0047] In this embodiment, the structure of the hanger 1 is characterized by the fact that the folding direction of each part, including the bottom fold line 51, the first hook fold line 55, the second hook fold line 56, the first shoulder fold line 52, the second shoulder fold line 54, the insert piece forming fold line 53, and furthermore, the first bending guide line 57 and the second bending guide line 58, can all be made in the same direction. Specifically, in the illustrated form, when assembling from the unfolded state shown in Figure 2, all the fold lines are mountain fold lines, and the folding direction is the same. In other words, at the bottom fold line 51, the first frame body 20A or the second frame body 20B is folded back toward the back of the paper; at the first hook fold line 55, the first hook reinforcing piece 33A is folded back toward the back of the paper; at the second hook fold line 56, the second hook reinforcing piece 33B is folded back toward the back of the paper; at the first shoulder fold line 52, the first shoulder upper forming piece 41 is folded back toward the back of the paper; at the second shoulder fold line 54, the second shoulder upper forming piece 43 is folded back toward the back of the paper; and at the insertion piece forming fold line 53, the insertion piece 42 is folded back toward the back of the paper. Similarly, when the first folding guide line 57 and the second folding guide line 58 are formed, one of the regions divided by the first folding guide line 57 and the second folding guide line 58 is folded back toward the back of the paper.

[0048] Therefore, in the hanger 1 of this embodiment, when forming the bottom fold line 51, the first hook fold line 55, the second hook fold line 56, the first shoulder fold line 52, the second shoulder fold line 54, and the insert piece forming fold line 53, as well as the first bending guide line 57 and the second bending guide line 58, it is desirable to form these as half slits on the same surface. Half slits allow the slit side to open when bent, making it easier to make a strong hanger. Even with a thick, flexible but rigid material, straight bends are easily made, making it easier to assemble a strong hanger. Furthermore, when half slits can be formed on the same surface, manufacturing becomes extremely easy compared to manufacturing methods that cut from both sides of the paper.

[0049] In the hanger 1 of this embodiment, when each fold line is a half-slit, the slit depth is not limited, but preferably the tensile strength between the slits should be 150N or more, preferably 170N or more. This significantly reduces the risk of unintentional breakage at the half-slit position during assembly, use, and folding. This tensile strength was measured using a sample that conforms to JIS P 8113, with dimensions of a rectangle of 15mm width x 180mm length, and a half-slit formed at the 90mm position (half the length). The measurement was performed with a tensile speed of 20mm / min and a load cell capacity of 1KN.

[0050] The hanger 1 of this embodiment, having the structure described above, has a three-dimensional form in which the upper shoulder forming piece 41 is bridged between the shoulders of the first frame body 20A and the second frame body 20B. Moreover, since the hook portion 3 is made of four layers and can be formed without thickness, it has excellent strength, and even when a dress cover is used, the opening of the dress cover is less likely to tear. Furthermore, since the unfolded state becomes a single sheet material like paper, it can be manufactured from a non-plastic sheet material. In addition, the folding direction of each part can be made in the same direction from the unfolded state, and half slits and creases can be formed from only one side and manufactured easily. Furthermore, after assembly, the hook portion 3 and the first frame body 20A and the second frame body 20B can be returned to the unfolded sheet state simply by releasing the engagement of the first locking groove 31m and the second locking groove 32m and pulling out the insertion piece 42 from the insertion part 44. In the illustrated configuration, the left and right directions were explained in the unfolded state shown in Figure 2, where the first apex 21 of the first frame body 20A is at the top of the paper and the second apex 25 of the second frame body 20B is at the bottom of the paper. It goes without saying that the left and right directions of the first right shoulder 22R, first left shoulder 22L, second right shoulder 26R, and second left shoulder 26L are merely arbitrary and change depending on the position of the hanger 1 and the viewer in the unfolded state.

[0051] Here, we will now describe a sheet material that is particularly suitable for the hanger 1 of this embodiment. From the viewpoint of reducing plastic use, the sheet material of this embodiment is preferably paper made from pulp fibers. Specifically, corrugated cardboard, coated cardboard, and multilayer paper with multiple layers of paper laminated together can be given as examples. Of course, it is even more desirable that the paper be composed only of fibers derived from natural materials and does not contain synthetic fibers including plastic. Preferably, paper made only of pulp fibers is desirable. Furthermore, a particularly preferred paper is multilayer paper having three or more layers of paper. As shown in Figure 13, since the multilayer paper 80 has multiple layers of paper 81 and 82 laminated together, the properties of each layer can be changed, making it strong yet easy to fold. For example, by combining a pair of surface layers 81 that are excellent in water resistance and abrasion resistance but are hard and tend to break easily with a flexible middle layer 82, it becomes possible to achieve excellent toughness and durability, making it strong yet easy to fold and assemble. Furthermore, when each fold line is made into a half-slit, multiple layers, including the surface layer, are not completely cut, and the risk of breakage at each fold line is significantly reduced. The multilayer paper 80 can be manufactured by multilayer papermaking. The multilayer paper 80 may be commercially available, for example, Elipla Paper manufactured by Dainichi Paper Co., Ltd.

[0052] When the sheet material is made of paper, the basis weight of the paper is preferably 300 g / m². 2 Above, a comfortable 330g / m² 2 In particular, 360 g / m² is preferred. 2 That concludes the explanation. With this basis weight paper, assembly by folding each part is easy, and it is also easy to use as a hanger with sufficient rigidity and strength. There is no upper limit to the basis weight, but there is a risk that creases will easily occur when folding with the calender roll during papermaking, so from this point of view, the upper limit should be 1400g / m². 2 Preferably, 1240 g / m² 2This is more preferable. Furthermore, when the sheet material is paper, the paper thickness is preferably 340 μm to 1400 μm, and more preferably 370 μm to 1350 μm. Note that the basis weight is the value measured in accordance with "Paper and cardboard - Method for measuring basis weight" described in JIS P 8124 (2011), and the paper thickness is the value measured in accordance with "Paper and cardboard - Test method for thickness and density" described in JIS-P8118 (2014).

[0053] When the sheet material is paper, 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), and bleached softwood kraft pulp (NBKP), and hardwood kraft pulp such as unbleached hardwood kraft pulp (LUKP), semi-bleached hardwood kraft pulp (LSBKP), and bleached hardwood kraft pulp (LBKP). Other pulps may be used in appropriate combinations of various known pulps, such as recycled paper pulp, hardwood sulfite pulp, softwood sulfite pulp, or pulp chemically or mechanically produced from non-wood fibers such as kenaf, hemp, and reed. It is desirable that softwood kraft pulp and hardwood kraft pulp make up 90-100% by mass, as this facilitates the development of strength. In this case, the mixing ratio of softwood kraft pulp to hardwood kraft pulp should preferably be 5:95 to 30:70. If the hanger is to have a clean and hard appearance, it is particularly preferable to use bleached softwood kraft pulp and bleached hardwood kraft pulp, which are white pulps with a high degree of whiteness.

[0054] When using paper as the sheet material, it is desirable that the paper has a tensile strength of 20 kN / m or more, preferably 25 kN / m or more, in both the longitudinal and transverse directions, as measured in accordance with JIS P 8113 (2006). Having this tensile strength makes it suitable for folding and assembly, and also facilitates the creation of hangers with sufficient strength.

[0055] Furthermore, if paper is used as the sheet material, it is desirable that the paper has a Taber stiffness of 120 mN·m or more in the longitudinal direction and 40 mN·m or more in the transverse direction, as measured in accordance with JIS P 8125 (2000). Within this range, sufficient rigidity and strength can be achieved for use as a hanger, and it is also easy to fold and assemble.

[0056] Furthermore, if the sheet material is paper, the Z-axis strength of that paper, measured in accordance with JAPAN TAPPI Paper Pulp Test Method No. 18-1:2000, must be 400 kN / m². 2 Preferably 450 kN / m 2 The above is desirable. It is easy to manufacture hangers in their unfolded state by die-cutting such as Thomson processing or cutting with a cutting plotter.

[0057] When using paper as the sheet material, it is desirable that the static friction coefficient of the paper, according to JIS P 8147 ISO horizontal method, be between 0.25 and 0.65. This provides adequate friction when clothing is hung on the paper, preventing it from slipping off easily, and also results in a surface that is less likely to damage the fabric. This measurement method involves taking three measurements each on the back surfaces of the sheet material and on the front surfaces, and it is desirable that the third measurement in both the back surfaces and front surfaces falls within the above range. The ISO horizontal method only requires measuring at least one of the static friction coefficients of the first slide, the third slide, or the third slide. The static friction coefficient of the third slide tends to be smaller than that of the first slide, and the variation in the static friction coefficient of the third slide is also smaller.

[0058] When the sheet material is paper, the paper should preferably have a PPS (Parker Print Surf Roughness) conforming to JIS P 8151, with a thickness of 3 to 8 μm on both the front and back surfaces, more preferably 4 to 7 μm. This provides a suitable surface texture that prevents clothing from slipping off when hung and also prevents damage to the fabric.

[0059] When the sheet material is paper, the paper preferably has an MMD value of 10 to 25 for both the front and back surfaces. It has an appropriate surface property that makes it difficult to slip off when covered with clothing and also difficult to damage the fabric. The MMD is measured using a friction feel tester (KES-SE, manufactured by Kato Tech Co., Ltd.) or an equivalent machine. Note that the friction element used has a contact surface with a length and width of 10 mm each, which is formed by adjacent 20 piano wires with a diameter of 0.5 mm attached as a standard.

[0060] When the sheet material is the multi-layer paper 80 particularly preferred for the hanger 1 according to the present embodiment, the number of layers is not limited, but is preferably five to nine layers, and the number of layers of the middle layer 82 is three or more, particularly five layers. In particular, the form shown in FIG. 13 has three middle layers 82. When the total number of the middle layers 82 is three or more, it is said that the toughness and durability of the multi-layer paper 80 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 82 is preferably seven layers or less. Also, three to seven layers are easy to operate while maintaining the interlayer strength when using a cylinder multi-former papermaking machine.

[0061] Note that when the sheet material is the multi-layer paper 80, the basis weight of the surface layer 81 and the middle layer 82 can be adjusted within the range of the overall basis weight when the above sheet material is paper, and is not particularly limited. Preferably, the basis weight of the surface layer 81 is 2 50.0 g / m per layer 2 to 150.0 g / m 2 per layer, particularly preferably 60 to 145 g / m 2 per layer. Also, the total basis weight of the middle layer 82 is 2 200 g / m 2 to 1100 g / m 2 per layer, particularly preferably 250 g / m 2 to 740 g / m 2 per layer. Further, the multi-layer paper 80 preferably has a ratio of the total basis weight of the pair of surface layers 81, 81 to the overall basis weight of the multi-layer paper 80 of 15.0% or more and 33.0% or less. The rigidity of the pair of surface layers 81 becomes high, and the flexibility of the middle layer 82 becomes excellent. Therefore, it is easy to bend at the fold line position and difficult to bend at positions other than the fold line, and it is easy to form a hanger excellent in strength and ease of assembly.

[0062] When the sheet material is multilayer paper 80, the composition of pulp fibers in each layer of the multilayer paper 80 is preferably such that the mass ratio (%) of softwood kraft pulp to hardwood kraft pulp in the surface layer 81 is 0 / 100 or more and 15 / 85 or less. In addition, along with the surface layer 81, the middle layer 82 preferably has a mass ratio (%) of softwood kraft pulp to hardwood kraft pulp of 15 / 85 or more and 35 / 65 or less. A large amount of hardwood kraft pulp, which is rigid and easily densened, is contained in the surface layer, resulting in high density and rigidity, while the middle layer contains a large amount of softwood kraft pulp, which is more flexible than the surface layer. As a result, the hanger tends to have less strength loss even when folded at each fold line during assembly and when repeatedly folded.

[0063] Furthermore, when the sheet material is multilayer paper 80, it is desirable that at least one of a sizing agent and a paper strength enhancer is added to the multilayer paper 80 as a papermaking additive. This makes it easier to adjust to the desired strength. In addition, the multilayer paper 80 may contain various other additives to the extent that it does not impair the effects intended for this invention. For example, polyvinyl alcohol or wax can be applied.

[0064] Examples of sizing agents include styrene-based sizing agents, alkyl ketene dimers (AKD), alkenyl succinic anhydride (ASA), neutral rosin sizing agents, rosin sizing agents, and modified rosin emulsion sizing agents. Among these, rosin sizing agents and modified rosin emulsion sizing agents are preferred. Rosin sizing agents are 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. Rosin sizing agents also include emulsions of these alone or mixtures, and emulsions of these alone followed by mixtures. Furthermore, emulsions to which various polymers are added to further improve sizing properties are also included.

[0065] Various known paper strength enhancers can be used, including polyacrylamide resins, polyamide resins, polyamine resins, acrylic resins, melamine resins, urea resins, and polyamide epichlorohydrin resins. Among these, it is preferable to use an amphoteric paper strength enhancer. Examples of amphoteric polyacrylamides include copolymers of acrylamide with anionic monomers and cationic monomers, Mannich-modified copolymers of acrylamide with anionic monomers, and Hoffmann decomposition products. In particular, amphoteric polyacrylamide has a self-fixing function, so even if it is added to improve inter-paper strength, it does not result in an excess of cations, and it can be stably fixed by including it together with a modified rosin emulsion sizing agent.

[0066] The amount of sizing agent added is preferably between 0.5 kg / t and 5.0 kg / t in terms of solid content. The amount of paper strength enhancer added is preferably between 12 kg / t and 30 kg / t in terms of solid content. Note that "kg / t" indicates the mass (kg) per ton of pulp. Adding sizing agent within this range increases water resistance, making it easier to maintain sufficient strength even when wet clothing or towels are hung on it.

[0067] Furthermore, when the sheet material is multilayer paper 80, it is preferable to add at least one of the above-mentioned sizing agent and paper strength enhancer as a papermaking additive to each layer of the multilayer paper 80, including the surface layer 81 and the middle layer 82. In this case, the amount of sizing agent added to the surface layer 81 is preferably 0.5 kg / t to 5.0 kg / t in solid content. The amount of sizing agent added to the middle layer 82 is preferably 2.0 kg / t to 5.0 kg / t in solid content. The amount of paper strength enhancer added to each layer is preferably 12 kg / t to 30 kg / t in solid content. By keeping the paper strength within this range, it is easier to achieve various paper strengths, such as interlayer strength, of the multilayer paper suitable for hangers.

[0068] Furthermore, it is desirable that the hanger according to this embodiment contains a siloxane compound. The presence of a siloxane compound increases rigidity, strength, and water resistance due to siloxane bonding. The siloxane compound is not necessarily limited as long as it has siloxane bonding, but since the hanger 1 is used to hang clothing that comes into contact with the human body, it is desirable that it is non-toxic or has low toxicity to living organisms. In addition to coating the hanger with the siloxane compound after assembly, the siloxane compound may also be incorporated by impregnating the sheet material before assembly or the sheet material as a base material with an appropriate alkoxysilane solution or an alkoxysilane solution processed product, and then heating or inducing heating. This is desirable because it allows the siloxane compound to be incorporated in a manner that it is bonded to the pulp fibers themselves or coats the pulp fibers.

[0069] Furthermore, the hanger according to this embodiment may be coated or impregnated with a surface protective agent, antibacterial agent, or antiviral agent, to the extent that it does not excessively alter the coefficient of friction, surface roughness, or folding suitability, and does not hinder the function of the hanger or the effects of the present invention.
