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 storing clothing in dry cleaners and homes (see Patent Documents 1 and 2 below). Furthermore, hotels and inns sometimes provide hard plastic or wooden hangers in the closets of guest rooms for their use.

[0003] Because hangers made of 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, which presents problems in terms of 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 hangers has been proposed, for example, in Patent Documents 3 and 4 below. Unlike injection-molded plastic hangers, these hangers are formed by folding and assembling a single thin sheet of material, so they can be transported and stored in sheet form, offering superior storage and transportability. For example, they can be delivered to stores or accommodations in sheet form, stored in the back room in sheet form, or assembled and used when needed. Disposal is also easy. [Prior art documents] [Patent Documents]

[0006] [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 [Overview of the project] [Problems that the invention aims to solve]

[0007] However, the hanger described in Patent Document 3 has a thin, plate-like body, and although it is possible to form a shoulder pad portion, it does not have a three-dimensional shape with sufficient thickness and width, so there is a risk of wrinkles and deformation of clothing due to prolonged use. In particular, it is not suitable for hanging heavy clothing such as coats, suits, and dresses. Furthermore, because the hanger body is thin, it does not have the design appeal of the high-quality, three-dimensional wooden or plastic hangers disclosed in Patent Document 2.

[0008] The hanger disclosed in Patent Document 4 has a wide shoulder section to prevent wrinkles and deformation of clothing, but it requires adhesive to join the hook and the main body. Furthermore, since there is no hook in the center of the thick main body, and a thin plate-like hook is attached to one side of the thick main body, there is a risk that the adhesive will peel off when heavy clothing is hung on it. In addition, it does not have a bar for hanging slacks or trousers, and is not suitable for hanging suits.

[0009] Furthermore, Patent Document 3 and Patent Document 4 These hangers all have the hook fixed to the main body, and the hook does not rotate relative to the main body, resulting in poor usability during use.

[0010] Therefore, the main objective of the present invention is to provide a hanger that can be assembled from a sheet without using adhesives or adhesive tapes, has a three-dimensional shape that prevents wrinkles and deformation of clothing, has sufficient strength to hang heavy clothing, has a hook that rotates for excellent operability, and also has a bar for hanging trousers and the like.

[Modes for carrying out the invention]

[0022] Next, embodiments of the present invention will be described in detail below with reference to Figures 1 to 14. However, the present invention is not limited to the illustrated shapes or these embodiments. Within the scope of the present invention, the detailed shapes and positions of each part can be changed to the extent that they do not impede the effects of the present invention. Furthermore, the terms "front," "back," "top," "bottom," "left," and "right" in the present invention and this specification are not terms that indicate absolute positions and vary depending on the viewer's position. In the hanger of this embodiment, the "front" and "back" do not need to coincide with the front and back when in use. Also, terms such as "first," "second," etc., do not necessarily indicate the order of operation.

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

[0024] The hanger body 2 has a top portion 10 to which the hook portion 3 is connected, a pair of shoulder portions 40A (40B) that extend diagonally outward from the top portion 10 to the left and right and gradually widen toward the shoulder tip 40E, and a connecting portion 60 that connects the shoulder portions 40A (40B) to each other. In particular, the shoulder portions 40A (40B) are wide and have a three-dimensional shape with overall thickness.

[0025] In this hanger 1, both the hanger body 2 and the hook 3 are formed from a single, thin, sheet-like material.

[0026] As shown in the unfolded state in Figure 2, the hanger body 2 has a shoulder portion 40A which includes a shoulder front forming piece 41, a shoulder upper forming piece 42 connected to the shoulder front forming piece 41 via a shoulder first fold line 51, and a shoulder back forming piece 43 connected to the shoulder upper forming piece 42 via a shoulder second fold line 52. In addition, the shoulder portion 40A in the forms shown in Figures 1 to 9 also has a shoulder bottom forming piece 44 which is connected to both the shoulder front forming piece 41 and the shoulder back forming piece 43 via a shoulder third fold line 53.

[0027] The shoulder portion 40A has a first shoulder fold line 51 and a second shoulder fold line 52 that are folded in a mountain fold, and the shoulder front forming piece 41, the shoulder upper forming piece 42, and the shoulder back forming piece 43 are connected in a roughly U-shape in cross-section, forming a three-dimensional shape with the shoulder front forming piece 41 as the shoulder front portion 41a, the shoulder upper forming piece 42 as the shoulder upper portion 42a, and the shoulder back forming piece 43 as the shoulder back portion 43a. In this embodiment of the hanger 1, the folding angles of the first shoulder fold line 51 and the shoulder second fold line 52 do not need to be the same, and by changing the folding angles, an asymmetrical shape can be created between the front and back sides. Also, the lengths of the first shoulder fold line 51 and the shoulder second fold line 52 do not need to be the same. If either is shortened, the shoulder portion will protrude on the shortened side, and an asymmetrical shape can be created between the front and back sides. For example, in the configurations shown in Figures 1 to 9, the second fold line 52 of the shoulder portion is shortened, and the shoulder portion 40A is configured to protrude on the back side. This makes it easier to distinguish between the front and back.

[0028] Furthermore, the shoulder portion 40A is configured such that at least one of the shoulder front forming piece 41, the shoulder upper forming piece 42, and the shoulder back forming piece 43 gradually widens from the top 10 side toward the shoulder tip 40E, thereby forming a wide, three-dimensional shoulder portion 40A (40B) in a top view. The specific shapes of the shoulder front forming piece 41, the shoulder upper forming piece 42, and the shoulder back forming piece 43 are not necessarily limited, but in the embodiments shown in Figures 1 to 9, the shoulder upper forming piece 42 has a shape in which the curved edge at the end toward the shoulder tip 40E gradually approaches and the width gradually narrows, and the shoulder front forming piece 41 and the shoulder back forming piece 43 have a shape in which the ends toward the shoulder tip 40E gradually widen. The shapes of the shoulder front forming piece 41 and the shoulder back forming piece 43 do not need to be the same, and in the embodiments shown in Figures 1 to 10, the shoulder tip side of the shoulder back forming piece 43 is formed to be wider than the shoulder tip side of the shoulder front forming piece 41. This results in a shoulder portion 40A having an asymmetrical shape on the front and back sides.

[0029] In the embodiments shown in Figures 1 to 9, the shoulder portion 40A preferably has a triangular front shoulder tip piece 45 extending from the front shoulder portion forming piece 41 via a first shoulder tip fold line 54, and a triangular rear shoulder tip piece 46 extending from the rear shoulder portion forming piece 43 via a second shoulder tip fold line 55, which are connected via a middle fold line 56 extending from the tip of the upper shoulder portion forming piece 42. The first shoulder tip fold line 54 and the second shoulder tip fold line 55 are mountain folds, and the middle fold line 56 is valley folds, and these folds bring the front shoulder tip piece 45 and the rear shoulder tip piece 46 close together so that they fit between the front shoulder portion forming piece 41 and the rear shoulder portion forming piece 43, and are then folded in half.

[0030] Furthermore, the shoulder portion 40A in the embodiments shown in Figures 1 to 9 preferably has a first shoulder bottom edge forming piece 47 extending from the front shoulder tip piece 45 via a tip fold line 57, and a second shoulder bottom edge forming piece 48 extending from the back shoulder tip piece 46 via a tip fold line 57. The first shoulder bottom edge forming piece 47 and the second shoulder bottom edge forming piece 48 are arranged to overlap and stack by inserting the front shoulder tip piece 45 and the back shoulder tip piece 46 between the shoulder front forming piece 41 and the shoulder back forming piece 43 while the tip fold line 57 is valley-folded or being valley-folded, and this stacking forms a shoulder bottom edge portion 47a on the bottom side of the shoulder tip 40E of the shoulder portion 40A. In the illustrated configuration, the first shoulder-bottom edge forming piece 47 has an insertion piece 47A extending from it, and a slit-shaped insertion portion 48B formed between the second shoulder-bottom edge forming piece 48 and the front-side shoulder piece 46. When the first shoulder-bottom edge forming piece 47 and the second shoulder-bottom edge forming piece 48 are stacked, the insertion piece 47A can be inserted into the insertion portion 48B, and this insertion connects the first shoulder-bottom edge forming piece 47 and the second shoulder-bottom edge forming piece 48, and they are stacked and integrated together.

[0031] In the shoulder portion 40A of the embodiment shown in Figures 1 to 9, preferably, when the first shoulder tip bottom edge forming piece 47 and the second shoulder tip bottom edge forming piece 48 are laminated and integrated, the shoulder tip bottom edge 47a is formed at the bottom of the shoulder tip 40E. As a result, the first shoulder tip fold line 54, the second shoulder tip fold line 55, and the edge 47E of the shoulder tip bottom edge 47a form a triangle, and the end of the shoulder tip 40E becomes a truss structure. Furthermore, in the illustrated form, together with the middle fold line 56, it becomes a three-dimensional truss structure. In this form, the strength near the shoulder tip 40E is greatly improved, so the risk of the tip of the shoulder portion 40A sagging or bending when heavy clothing is hung on it is significantly reduced. However, in the hanger 1 of this embodiment, the front shoulder tip piece 45, the back shoulder tip piece 46, the first shoulder tip bottom edge forming piece 47, and the second shoulder tip bottom edge forming piece 48 are not necessary. The shoulder portion 40A can be formed even without these pieces.

[0032] On the other hand, the connecting portion 60 in the hanger 1 of this embodiment has a connecting portion front portion 61 that is located between the shoulder portion front forming pieces 41 and is integrally connected to each shoulder portion front forming piece 41, a pair of connecting portion back forming pieces 62 that extend from each shoulder portion back forming piece 43, and engaging portions 63 formed on each connecting portion back forming piece 62 that connect the connecting portion back forming pieces 62 to each other to form a connecting portion back portion 62a. The connecting portion front portion 61 is not limited, but it is desirable that it constitutes an area integral with the shoulder portion front forming piece 41 without the need for fold lines or the like.

[0033] In this embodiment, the connecting portion 60 of the hanger 1 is configured such that the engaging portions 63 formed on the back forming piece 62 of the connecting portion are in close proximity to each other when the first shoulder fold line 51 and the second shoulder fold line 52 are bent, and the engaging portions 63 engage to form the back portion 62a of the connecting portion that faces the front portion 61 of the connecting portion. In the illustrated form, the engaging portions 63 are engaging grooves formed on each back forming piece 62 of the connecting portion, and the hangers are easily connected by interlocking these engaging grooves. However, the engagement of the engaging portions is not limited to this. For example, they may be engaged by inserting an insertion piece into a slit-shaped insertion portion. However, it is preferable to use the form in which the engaging grooves are interlocked as shown in the illustration. This engagement form provides a strong connection in the tensile direction, so it can strongly connect against the force that causes the back forming pieces 43 of the shoulders to open when heavy clothing is hung on them.

[0034] On the other hand, in the hanger 1 of this embodiment, the connecting portion 60 is provided with a connecting portion bottom forming piece 65 that is connected to the connecting portion back forming piece 62 via a connecting portion fold line 64, and the connecting portion fold line 64 is folded in a mountain fold so that the connecting portion bottom forming piece 65 forms the connecting portion bottom portion 65a. It is desirable that the connecting portion bottom portion 65a is formed on the connecting portion 60 in this way because it makes it less likely for the space between the connecting portion back portion 62a and the connecting portion front portion 61 to be crushed.

[0035] On the other hand, the top portion 10 of the hanger 1 of this embodiment includes a top first bottom surface forming piece 11 connected to the bottom edge of the connecting portion front portion 61 via a top first fold line 21, a top back surface forming piece 12 connected to the top first bottom surface forming piece 11 via a top second fold line 22, a top top surface forming piece 13 connected to the top back surface forming piece 12 via a top third fold line 23, a connecting hole 14 to which a hook portion 3 formed in the top top surface forming piece 13 is connected, a top front surface forming piece 15 connected to the top top surface forming piece 13 via a top fourth fold line 24, a top second bottom surface forming piece 16 connected to the top front surface forming piece 15 via a top fifth fold line 25, a top insertion piece 17 connected to the top second bottom surface forming piece 16 via a top sixth fold line 26, and a top insertion portion 18 into which the top insertion piece 17 is inserted.

[0036] In this embodiment, the top portion 10 of the hanger 1 is configured such that, with the connecting portion back forming piece 62 engaged to form the connecting portion back portion 62a, the top first fold line 21, top second fold line 22, top third fold line 23, top fourth fold line 24, top fifth fold line 25, and top sixth fold line 26 are mountain-folded to surround the connecting portion 60. Specifically, the top first fold line 21, top second fold line 22, top third fold line 23, top fourth fold line 24, top fifth fold line 25, and top sixth fold line 26 are mountain-folded, the top first bottom forming piece 11 becomes the top first bottom portion 11a that supports the bottom edge side of the connecting portion front portion 61 and the connecting portion back portion 62a, the top back forming piece 12 becomes the top back portion 12a that overlaps the connecting portion back portion 62a, and the top top forming piece 13 is connected to the hook portion 3. The top surface portion 13a has a connecting hole 14, the top front forming piece 15 is formed as the top front portion 15a which overlaps the connecting portion front portion 61, and the top second bottom forming piece 16 is formed as the top second bottom portion 16a which overlaps the top first bottom portion 11a. The top insertion piece 17 is insertable into the top insertion portion 18, and the top insertion piece 17 is formed by being inserted into the top insertion portion 18.

[0037] The position and shape of the top insertion piece 17 and the top insertion portion 18 are not limited. In the illustrated form, the top insertion portion 18 is a slit hole located between the top first bottom surface forming piece 11 and the top back surface forming piece 12, and the top portion 10 is formed by inserting the top insertion piece 17 into this slit hole, the top insertion portion 18. The top back surface forming piece 12 is located in a position that overlaps with the back surface portion 62a of the connecting portion, so when the top insertion portion 18 is in this position, the top insertion piece 17 is inserted so that it overlaps with the back surface portion 62a of the connecting portion, which is also the engaging portion of the back surface forming piece 62 of the connecting portion, thus reinforcing the fragile engaging portion 63, which is desirable.

[0038] In this embodiment, the top portion 10 of the hanger 1 preferably includes a top side forming piece 19 connected to the top top surface forming piece 13 via a top seventh fold line 27, a shoulder upper connecting piece 19E connected to the top side forming piece 19 via a top eighth fold line 28, a top second front forming piece 15B connected to the top side forming piece 19 via a top ninth fold line 29A and connected to the top front forming piece 15 via a top tenth fold line 29B, and a top second back forming piece 12B connected to the top side forming piece 19 via a top eleventh fold line 29C and connected to the top back forming piece 12 via a top twelfth fold line 29D.

[0039] Then, the top portion 10 is formed by folding the seventh fold line 27 of the top portion into a mountain fold, folding the eighth fold line 28 into a valley fold, folding the ninth fold line 29A and the eleventh fold line 29C into valley folds, and folding the tenth fold line 29B and the twelfth fold line 29D into mountain folds, so that the top side forming piece 19 becomes the top side portion 19a that hangs down from the top surface portion 13a, and the shoulder upper connecting piece 19E extends from the bottom edge side of the top side portion 19a to the shoulder upper The upper shoulder connecting portion 19e is connected to portion 42a, the second top front forming piece 15B overlaps the top front portion 15a, the second top back forming piece 12B overlaps the top back portion 12a, and at least a portion of the upper shoulder connecting piece 19E, the top side forming piece 19, the second top front forming piece 15B, and the second top back forming piece 12B are located between the connecting portion front portion 61 and the connecting portion back portion 62a.

[0040] In this preferred form of the top portion 10, the second top front forming piece 15B and the top front portion 15a overlap, and the second top back forming piece 12B overlaps the top back portion 12a, so that the top front portion 15a and a part of the top back portion 12a have a double structure, which increases their strength. Furthermore, the top side portion 19a is suspended from the top top surface portion 13a, and the top side portion 19a, the second top front forming piece 15B, and a part of the second top back forming piece 12B are located between the connecting portion front portion 61 and the connecting portion back portion 62a, so that the space between the connecting portion front portion 61 and the connecting portion back portion 62a is extremely resistant to crushing. In addition, since the shoulder upper connecting portion 19e is formed from the bottom edge side of the top side portion 19a and extends to the shoulder upper portion 42a, the strength is particularly increased at the connection point between the shoulder portion 40A and the connecting portion 60. In particular, the top portion 10 is the part to which the hook portion 3 is connected, so it is desirable that it be made to have high strength; therefore, it is preferable to make the top portion 10 in this desirable shape.

[0041] On the other hand, in this embodiment, the hanger 1 has a hook portion 3 which includes an upper hook portion 3T having a hook portion 3F and a lower insertion portion 3U that is inserted into a connection hole 14. The lower insertion portion 3U is inserted into a connection hole 14 formed in the top surface portion 13a and is rotatably connected to the hanger body portion 2. The method of connecting the hook portion 3 and the hanger body portion 2 is not limited. The illustrated form is a preferred form and has a distinctive structure that ensures smooth rotation of the hook portion 3, ease of assembly, connection strength, and prevents the hook portion 3 from coming out of the connection hole 14.

[0042] In other words, in the hanger 1 of this embodiment, the connecting hole 14 has a circular hole portion 14A and an enlarged diameter portion 14B for insertion that extends from the outer edge of the circular hole portion 14A, and the hook portion 3 has a hook portion body piece 30 and an anti-slip piece 35. The hook portion body piece 30 and the anti-slip piece 35 are thin plates and are formed from a single sheet material. As shown in Figure 8(A), the hook portion body piece 30 and the anti-slip piece 35 can be in the form of a single layer structure in which the sheet material is cut into the shapes of the hook portion body piece 30 and the anti-slip piece 35, or as shown in Figure 8(B), the portions forming the shapes of the hook portion body piece 30 and the anti-slip piece 35 can be formed symmetrically along a fold line P, and the fold line P can be folded back to form a double-layered structure. In this case, the strength of each part is further increased.

[0043] The hook portion body piece 30 has an insertion lower part 3U that is wider than the diameter of the circular hole portion 14A and can pass only through the insertion enlarged diameter portion 14B, a pair of guide groove portions 31 formed on the upper part of the insertion lower part 3U and arranged so that the groove bottoms face each other, and an elongated anti-slip piece insertion hole 32 formed between the guide groove portions in a direction perpendicular to the guide groove portions 31.

[0044] The hook body piece 30 is connected to the top 10 such that its insertion lower part 3U is inserted through the connection hole 14 below the top surface 13a, and the outer edge 14e of the circular hole 14A fits into the guide groove 31, and the upper part 3T of the hook is erected on the top surface 13a, with the hook body piece 30 rotatably connected to the circular hole 14A so as to be guided by the outer edge 14e of the circular hole 14A and the guide groove 31. The insertion lower part 3U of the hook body piece 30 can be inserted below the top surface 13a through the insertion enlargement part 14B, and by rotating the hook body piece 30 in the circumferential direction of the circular hole 14A when the guide groove 31 and the outer edge 14e of the circular hole 14A coincide, the guide groove 31 fits into the outer edge 14e of the circular hole 14A.

[0045] The insertion-type enlarged portion 14B extending from the outer edge of the circular hole portion 14A is formed to be approximately the same thickness as or slightly wider than the hook portion body piece 30. In the illustrated form, a particularly preferred form is that the insertion-type enlarged portion 14B is formed by a roughly U-shaped slit rather than by punching, so that a tongue piece 14b is formed. In this form, after insertion of the insertion lower portion 3U, this tongue piece 14b acts as a return, more effectively preventing the hook portion body piece 30 from coming out.

[0046] The anti-slip piece 35 has a bottom edge 35E that is wider than the diameter of the circular hole 14A, and is inserted into the anti-slip piece insertion hole 32 of the hook body piece 30, so that it is erected on the top surface 13a. In this configuration, the hook body piece 30 and the anti-slip piece 35 are arranged in a cross shape when viewed from above, as shown in Figure 5, and are erected on the top surface 13a. This effectively prevents the hook body piece 30 from breaking near the edge of the circular hole 14A at the connection point, and also makes it easier for the hook 3 to rotate.

[0047] In the illustrated form, the anti-slip piece 35 has a preferred shape, having a groove 36 at its upper part, and forming a lap joint with the upper part of the anti-slip piece insertion hole 32 formed in the hook body piece 30. Therefore, after inserting the anti-slip piece 35 into the anti-slip piece insertion hole 32, it is configured to slide upward from the insertion position to a position where the bottom of the groove 36 of the anti-slip piece 35 contacts the upper edge of the anti-slip piece insertion hole 32. In the illustrated preferred form, when the anti-slip piece 35 is slid upward, the bottom edge 35E of the anti-slip piece 35 is positioned above the guide groove 31 of the hook body piece 30, and the hook body piece 30 can be inserted into the connection hole 14 with the hook body piece 30 and the anti-slip piece 35 assembled. Furthermore, when the hook portion 3 and the top surface portion 13a are connected, the interlocking joint structure does not come apart, and the bottom edge 35E of the anti-detachment piece 35 is positioned above the connection hole 14. In the connected state, the anti-detachment piece 35 is also prevented from coming out of the anti-detachment piece insertion hole 32. Thus, in the illustrated configuration, the hook portion body piece 30 and the anti-detachment piece 35 are erected in a cross shape when viewed from above above, allowing the hook portion 3 to rotate smoothly and making it less likely to break. Moreover, it can be easily assembled without the need for adhesives, and the connection strength and the prevention of the hook portion 3 coming out of the connection hole 14 are effectively maintained.

[0048] Furthermore, by interposing the reinforcing piece 38, as shown in Figure 8(A), between the top surface portion 13a and the hook portion, the hook portion is less likely to come loose, and the top surface portion 13a becomes substantially a double structure, reinforcing the connection portion. The reinforcing piece 38 has a circular hole portion and an enlarged diameter portion for insertion, the same shape as the connection hole 14, and the enlarged diameter portion 14B of the reinforcing piece 38 are aligned, allowing the insertion lower part 3U of the hook portion 3 to be inserted. After insertion, the positions of the connection hole 14, the enlarged diameter portion 14B of the reinforcing piece and the enlarged diameter portion 14C of the reinforcing piece become misaligned, making it more difficult for the hook portion 3 to come loose.

[0049] On the other hand, in the hanger 1 of this embodiment, a preferred configuration includes a suspension bar 70 connected to each end of a pair of shoulder portions 40A and bridging the space between the shoulder portions 40A, so that slacks, pants, etc., can be hung on it. This suspension bar 70 is also assembled from a single sheet material. As shown in Figures 1, 3, and 4, this suspension bar 70 is characterized by having a bar portion 71 with a wavy edge 70E at the top.

[0050] The bar portion 71 is formed by bending a pair of elongated bar portion forming pieces 75, which are connected via a bar portion forming bending line 72, along the bar portion forming bending line 72 to form an elongated bar-shaped section with a V-shaped cross-section. The wavy edge 70E of this bar portion 71 is characterized in that, as shown in the unfolded state before bending in Figure 9, peaks 73 and valleys 74 are alternately positioned on either side of the extension of the bar portion forming bending line 72, and the wavy slit 70S is formed when the bar portion forming bending line 72 is bent, causing the edge of the slit 70S to stand up. Therefore, the wavy edge 70E has peaks and valleys alternately positioned on each bar portion forming piece 75 in the direction along the bar portion forming bending line 72, and the peaks and valleys of each bent bar portion forming piece 75 are in opposing positions. The bending angle between the pair of bar portion forming pieces 75 is not limited. Increasing the angle between the bar-forming pieces 75 results in a wider shape with smaller peaks and valleys, while decreasing the angle between the bar-forming pieces 75 results in a narrower shape with larger peaks and valleys. These can be adjusted as appropriate. The height and depth of the peaks 73 and valleys 74 are also not limited and can be designed as appropriate. Furthermore, in the illustrated form, the wavy edge 70E is formed in two places, but the length and number of wavy edges 70E are not limited and can be designed as appropriate. This bar section 71 can be easily constructed with a wavy edge by simply bending the sheet material, and can also be made into a thick, three-dimensional shape. In addition, since the peaks and valleys are alternately positioned on each piece, clothing such as pants are effectively prevented from slipping off when hung. Furthermore, the design has a distinctive feature in that the peaks 73 and valleys 74 of each bent bar-forming piece 75 are in opposing positions.

[0051] In the hanger 1 of this embodiment, the connection method between the suspension bar 70 and the shoulder portion 40A is not limited. In the configurations shown in Figures 1 to 9, connecting insert pieces 77 are formed at both ends of each bar portion forming piece 75, and connecting insert holes 78 are formed at the lower part of each end of the shoulder portion 40A. The connection is made by inserting the insert pieces 77 into the insert holes 78 without using adhesive or the like. In particular, in the configurations shown in Figures 1 to 9, a preferred configuration is in which the insert pieces 77 are inserted into the insert holes 78 formed in the front shoulder tip piece 45 and the back shoulder tip piece 46, which are three-dimensional trusses at the tip of the shoulder portion 40A, thereby providing high strength against downward pulling of the suspension bar.

[0052] Next, another form of the hanger 1 of this embodiment, in which the shoulder portion differs from the form shown in Figures 1 to 9, will be described with reference to Figures 10 to 13. In addition to the shoulder portion 40B, the structure of the suspension bar 70 also differs in this embodiment of the hanger 1. However, the suspension bar 70 may be the same as the suspension bar described in Figures 1 to 9. Furthermore, the suspension bar of the embodiment shown in Figures 11 to 13 can be the same as the suspension bar of the embodiment shown in Figures 1 to 9. Note that the structure of the shoulder portion, such as the connecting portion 60, the top portion 10, the hook portion 3, and the connection between the hook portion 3 and the top portion 10, and the configuration other than the suspension bar are the same as those of the embodiment shown in Figures 1 to 9 described earlier.

[0053] In the embodiment shown in Figures 10 to 13, the shoulder portion 40B of the hanger has a shoulder upper forming piece 42 that gradually widens towards the shoulder tip 40E, unlike the shoulder portion 40A in the embodiment shown in Figures 1 to 9. Furthermore, in addition to the shoulder front forming piece 41, the shoulder upper forming piece 42 connected to the shoulder front forming piece 41 via the shoulder first fold line 51, and the shoulder back forming piece 43 connected to the shoulder upper forming piece 42 via the shoulder second fold line 52, the shoulder bottom forming piece 44 connected to the shoulder back forming piece 43 via the shoulder third fold line 53, and the shoulder vertical surface forming piece 49 connected to the shoulder tip 40E side end of the shoulder bottom forming piece 44 via the shoulder fourth fold line 59.

[0054] This shoulder portion 40B is formed by folding a third shoulder fold line 53 in addition to the first shoulder fold line 51 and the second shoulder fold line 52, creating a box shape in which the shoulder front forming piece 41 becomes the shoulder front portion 41a, the shoulder upper forming piece 42 becomes the shoulder upper portion 42a, the shoulder back forming piece 43 becomes the shoulder back portion 43a, and the shoulder bottom forming piece 44 becomes the shoulder bottom portion 44a. Furthermore, a fourth shoulder fold line 59 is folded to form a shoulder upright surface portion 49a at the shoulder tip end of the shoulder bottom portion 44a, and the upper edge 49E of this shoulder upright surface portion 49a is located on the bottom side of the shoulder upper portion 42a and supports it.

[0055] In this shoulder portion 40B, it is particularly desirable that the bottom surface portion 44a of the shoulder portion and the front surface portion 41a of the shoulder portion are connected in order to make this box-shaped structure robust. In the illustrated form, in a preferred configuration, the shoulder portion 40B further includes a shoulder insertion portion forming piece 145 connected to the shoulder bottom forming piece 44 via a fifth shoulder fold line 155, a shoulder insertion piece 146 connected to the shoulder front forming piece 41 via a sixth shoulder fold line 156, and a shoulder insertion portion 147 formed between the shoulder bottom forming piece 44 and the shoulder insertion portion forming piece 145 into which the shoulder insertion piece 146 is inserted. The fifth shoulder fold line 155 and the sixth shoulder fold line 156 are folded, and the shoulder insertion piece 146 is inserted into the shoulder insertion portion 147, thereby connecting the shoulder bottom portion 44a and the shoulder front portion 41a without the use of adhesive or the like, forming a strong box-shaped structure.

[0056] In the embodiment shown in Figures 10 to 13, the structure of the shoulder portion 40B of the hanger 1 allows the edge of the shoulder tip 40E side of the shoulder upper forming piece 42 to extend further toward the shoulder tip than the edges of the shoulder front portion 41a and the shoulder back portion 43a on the shoulder tip 40E side, allowing for free shaping of the edge of the shoulder upper portion 42a and enhancing the design. In the illustrated form, the edge is curved, creating a soft and luxurious design. In the illustrated form, as a preferred form, the shoulder upper portion 42a, formed by the shoulder upper forming piece 42 between the shoulder front portion 41a, formed by the shoulder front forming piece 41, and the shoulder back portion 43a, formed by the shoulder back forming piece 43, forms a curved surface with the top surface convex from the front to the back. In the illustrated form, multiple fold lines 42S are formed in parallel from the top portion 10 side toward the shoulder tip 40E side to facilitate the formation of this curved surface of the shoulder upper portion 42a. Furthermore, these fold lines 42S are arranged so as to be spaced apart from each other, extending from the top 10 side towards the shoulder tip 40E side, creating a widening shape from the top 10 side towards the shoulder tip 40E side, giving it a sophisticated and elegant design.

[0057] In the embodiments shown in Figures 10 to 13, the shoulder portion 40B of the hanger 1 has, in a preferred form, different shapes for the shoulder front forming piece 41 and the shoulder back forming piece 43. In particular, the width (height) of the shoulder front portion 41a, which is made up of the shoulder front forming piece 41, and the shoulder back portion 43a, which is made up of the shoulder back forming piece 43, are different. As a result, the shoulder upper portion 42a, which is made up of the shoulder upper forming piece 42, is configured to slope slightly downward from the back to the front. When clothing is hung so that the back of the hanger 1 and the back of the clothing are aligned, the shoulder portion easily follows the shoulder line of the clothing, and the occurrence of wrinkles in the clothing is more effectively prevented.

[0058] On the other hand, in the hanger 1 of the embodiment shown in Figures 10 to 13, the suspension bar 70 has an extension piece 79 for positioning the bar portion 71 below and spaced apart from the shoulder portion 40B. This suspension bar 70 is assembled from a single sheet material and, in its unfolded state, as shown in Figure 13, has a pair of elongated bar portion forming pieces 75 connected via a bar portion forming fold line 72, and a wave-shaped slit 70S arranged so that peaks and valleys alternate on either side of the extension position of the bar portion forming fold line 72. In this suspension bar 70 having extension pieces 79, there is further an extension piece first forming portion 79A that extends integrally from the end of one bar portion forming piece 75, and a second extension piece forming portion 79B that is connected to the end of the one bar portion forming piece 75 via a fold line 79S and has a shape symmetrical to the first extension piece forming portion by this fold line 79S. The extension piece 79 is formed by folding the second extension piece forming portion 79B over the extension piece first forming portion 79A using the fold line 79S. The configuration of the bar portion 71 is the same as that of the hanger in the embodiment shown in Figures 1 to 9, with a wavy edge 70E formed on the upper part. As shown in the figure, this suspension bar 70 has a roughly U-shape in front view, with the bar portion bridged between the lower ends of a pair of extension pieces 79.

[0059] Even in the suspension bar 70 having this extension piece 79, the connection configuration with the shoulder portion 40B is not limited. re No. In the illustrated configuration, an insertion hole 79X is formed in the shoulder bottom surface forming piece 44 of the shoulder portion 40B, and when it is made into the shoulder bottom surface portion 44a, the insertion hole 79X is located on the bottom surface side of the shoulder portion 40B. Furthermore, the tip of the extension piece 79 is configured to form a hook-shaped locking piece portion 79Y, and the connection is made by inserting and locking this locking piece portion 79Y into the insertion hole 79X.

[0060] Furthermore, in the embodiment shown in Figures 10 to 13, the hanging bar 70 of the hanger 1 has, in a particularly preferred form, a clamping bar 80 that holds clothing between itself and the bar portion 71. This clamping bar 80 is also made of a single sheet material and has a pair of elongated clamping bar forming pieces 82 connected via a fold line 81, and a pair of through holes 83 located between the clamping bar forming pieces at each end of the pair of clamping bar forming pieces 82. The clamping bar forming pieces 82 are generally about the same size as the bar portion forming pieces and are formed in a V-shape with a convex upper surface via the fold line 81. The angle between the clamping bar forming pieces 82 is not limited, but is formed to overlap with the bar portion 71.

[0061] On the other hand, the through holes 83 of the clamping bar 80 are sized to allow the extension pieces 79 to be loosely fitted into each through hole 83, so that the clamping bar 80 is bridged between the extension pieces 79 so that it can move up and down. Therefore, with this suspension bar 70, if clothing such as pants is hung on the bar portion 71 of the suspension bar 70 and the clamping bar 80 is placed on top of the bar portion 71, the clothing is clamped between the bar portion 71 and the clamping bar 80, and the clothing is more effectively prevented from falling off.

[0062] Here, the fold lines in the hanger 1 of this embodiment are lines that facilitate folding and bending of the sheet material, and may be simple printed lines for positioning, but preferably they are score lines, perforations, or half-slits, also called fold lines. Furthermore, it is not necessary for all of them to be the same type of line; for example, the first shoulder fold line and the second shoulder fold line that form the shoulder portion may be fold lines, and the wavy slits that form the bar portion may be half-slits, and they can be appropriately arranged considering the required strength and the stress required for folding. Also, the cut tie ratio when using perforations and the slit depth when using half-slits do not need to be the same.

[0063] In the case where the fold line in the hanger 1 of this embodiment 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.

[0064] The hanger of this embodiment can be assembled without the use of adhesives or adhesive tape, as each part is made by folding a single sheet material and engaging or inserting pieces. Furthermore, the upper shoulder forming piece 42 can be formed wide, and the shoulder front part 41a and shoulder back part 43a formed by the shoulder front forming piece 41 and shoulder back forming piece 43 can form wide, three-dimensional shoulder parts 40A and 40B, resulting in a three-dimensional shape that makes it difficult for clothes to wrinkle or lose their shape when hung. In addition to the configuration of the shoulder parts 40A and 40B, each piece constituting the top part 10 is configured to surround and cover the connecting part 60, and in a particularly preferred form, a top side part 19a is formed, providing sufficient strength to hang particularly heavy clothing. Furthermore, the hook part 3 has excellent rotatable operation, is difficult to detach, and can be firmly connected to the hanger body part 2. Furthermore, it can also have a bar part 71 for hanging pants, slacks, etc. Furthermore, the sheet materials that make up each part can be made from paper produced by papermaking using pulp fibers, thereby achieving plastic-free design.

[0065] Here, we will now describe a sheet material that is particularly suitable for the hanger 1 of this embodiment. As mentioned above, 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 to have paper made only from natural material fibers that do not contain synthetic fibers including plastic. Preferably, paper made only from pulp fibers is desirable. Furthermore, a particularly preferred paper is multilayer paper having three or more layers of paper. As shown in Figure 14, since the multilayer paper 90 has multiple layers of paper 91 and 92 laminated together, the properties of each layer can be changed, making it easy to fold while maintaining strength. For example, by combining a pair of surface layers 91 that are excellent in water resistance and abrasion resistance but are hard and tend to break easily with a flexible middle layer 92, it becomes possible to achieve excellent toughness and durability, making it easy to fold and assemble while maintaining strength. 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 90 can be manufactured by multilayer papermaking. The multilayer paper 90 may be commercially available, for example, Elipla Paper manufactured by Dainichi Paper Co., Ltd.

[0066] When the sheet material is made of paper, the basis weight of the paper is preferably 400 g / m². 2 Above, a comfortable 430g / m² 2 In particular, 460 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 500 μm or more and 1,400 μm or less, and more preferably 550 μm or more and 1,350 μm or less. 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).

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] When the sheet material is paper, the paper preferably has an MMD value of 10 to 25 on both the front and back surfaces. It has an appropriate surface property that makes it difficult to slip off when clothes are hung and difficult to damage the fabric. The MMD is measured using a friction sensation tester (KES-SE, manufactured by Kato Tech Co., Ltd.) or an equivalent machine. The friction element used is one having a contact surface with a length and width of 10 mm each, which is composed of 20 adjacent piano wires with a diameter of 0.5 mm attached as a standard.

[0074] When the sheet material is the multi-layer paper 90 particularly preferable 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 92 is three or more, particularly five layers. In particular, the form shown in FIG. 14 has three middle layers 92. When the total number of the middle layers 92 is three or more, the toughness and durability of the multi-layer paper 90 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. Also, three to seven layers are easy to operate while maintaining the interlayer strength when using a cylinder multi-former papermaking machine.

[0075] When the sheet material is the multi-layer paper 90, the basis weight of the surface layer 91 and the middle layer 92 can be adjusted within the range of the total basis weight of the sheet material when the sheet material is paper, and is not particularly limited. Preferably, the basis weight of the surface layer 91 is 2 55.0 g / m per layer 2 to 150.0 g / m 2 and particularly preferably 60 to 145 g / m 2 The basis weight of the entire middle layer 92 is 2 490 g / m 2 to 750 g / m 2 and particularly preferably 495 g / m 2 to 740 g / m 2 Furthermore, the multi-layer paper 90 preferably has a ratio of the total basis weight of the pair of surface layers 91, 91 to the total basis weight of the multi-layer paper 90 of 15.0% or more and 33.0% or less. The rigidity of the pair of surface layers 91 is high, and the flexibility of the middle layer 92 is 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.

[0076] When the sheet material is multilayer paper 90, the composition of pulp fibers in each layer of the multilayer paper 90 is preferably such that the mass ratio (%) of softwood kraft pulp to hardwood kraft pulp in the surface layer 91 is 0 / 100 or more and 15 / 85 or less. In addition, together with the surface layer 91, the middle layer 92 is preferably such that the mass ratio (%) of softwood kraft pulp to hardwood kraft pulp is 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 a high-density and rigid surface layer, 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.

[0077] Furthermore, when the sheet material is multilayer paper 90, it is desirable that at least one of a sizing agent and a paper strength enhancer is added to the multilayer paper 90 as a papermaking additive. This makes it easier to adjust to the desired strength. In addition, the multilayer paper 90 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] Furthermore, when the sheet material is multilayer paper 90, 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 90, including the surface layer 91 and the middle layer 92. In this case, the amount of sizing agent added to the surface layer 91 is preferably 0.5 kg / t to 5.0 kg / t in solid content. The amount of sizing agent added to the middle layer 92 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.

[0082] 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.

[0083] Furthermore, the hanger according to this embodiment may be coated or impregnated with a surface protective agent, antibacterial agent, or antiviral agent, as long as 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. [Examples]

[0084] A hanger according to the present invention (example) was fabricated and subjected to strength testing. The hanger according to the created embodiment was assembled without using adhesives or the like from the unfolded diagram shown in Figure 2, and had the form of a shoulder portion 40A and a suspension bar as shown in Figures 1 to 10. The dimensions of this hanger were a three-dimensional shape with a length of 415 mm between the shoulder tips, a maximum width of 75 mm for the shoulder portion, and a distance of 30 mm between the front and back of the top portion. The hook portion had a double structure as shown in Figure 8(B), consisting of a hook body piece and an anti-slip piece, and was rotatably connected to the top portion.

[0085] Furthermore, the hanger in the embodiment has a hook portion and a hanger body portion made of multilayer paper (475g / m² Elipla Paper manufactured by Dainichi Paper Co., Ltd.) 2 ) was created using multilayer paper (Dainichi Paper Co., Ltd.'s Elipla Paper 885g / m²) and the hanging bar was made of multilayer paper. 2 Created using ).

[0086] In the test, a men's wool suit (jacket 539g, trousers 346g) was hung on the hanger according to this embodiment and suspended from a metal wire locking bar for 10 days. The suit was then visually inspected for any bending or damage to the shoulder area. The jacket was hung on the hanger body, and the trousers were hung on the bar of the hanging bar.

[0087] The test results showed no breaks, bends, or other damage to the hangers after 10 days. Furthermore, on the 10th day, two commercially available PET bottles (1 bottle, 900mL, 967g each) were placed in the left and right front pockets of a jacket to apply additional load, and the shape of the hangers was visually inspected, but no breaks, bends, or other damage were observed.

[0088] The above tests demonstrate that the hanger structure according to the present invention can be assembled from a single sheet material, has a three-dimensional shape that prevents wrinkles and deformation of clothing, is strong enough to hang heavy garments, has excellent operability with a rotating hook, and also has a bar for hanging trousers and the like, making it a practical hanger.
