Description

[Technical Field]

[0001] The present disclosure relates to a comforter having an interior space for receiving contents. [Background technology]

[0002] Japanese Patent Application Laid-Open Publication No. 2003-144285 describes a futon with a three-dimensional quilt structure in which the outer and inner linings are sewn together at the four peripheral edges to form compartments inside. The inside of the lining is provided with two vertical bars that extend the entire length of the futon in the vertical direction and multiple horizontal bars that extend along the futon's width, with multiple intersections where the vertical bars and horizontal bars intersect.

[0003] Each of the vertical and horizontal bars is sewn to the lining at the seam allowance. At the intersection, the vertical bars extend in the vertical direction of the futon, and a pair of horizontal bars is provided on both sides of the vertical bars in the horizontal direction. A gap is formed between the pair of horizontal bars and the vertical bars. The horizontal bars are not sewn directly to the vertical bars, but are connected to the vertical bars via a patch cloth.

[0004] Four patches are used for one intersection. Each patch is L-shaped in plan view, with the vertical bar of the L shape sewn to the vertical bars and the horizontal bar of the L shape sewn to the horizontal bars. The entire surface of the horizontal bar of the L-shaped patch is connected to the horizontal bars. The upper and lower edges of the L-shaped vertical bar of the patch are connected to the vertical bars, and the space between the upper and lower edges is spaced apart from the vertical bars. The part of the patch that is spaced apart from the vertical bars and the gap formed between the horizontal bars and the vertical bars form a passage through which a feather filling pipe passes. Feathers are filled into the compartment from the feather filling pipe, with the feather filling pipe passing through the passage formed between the vertical bars and the patch or horizontal bars.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-144285 Summary of the Invention [Problem to be solved by the invention]

[0006] In the above-mentioned quilt, four patches are used at the intersections where the vertical and horizontal bars intersect. Because four patches must be prepared for each intersection, the cost of the fabric used as patches is high. Furthermore, because four patches are sewn at each of the multiple intersections of the quilt, the patches may cause discomfort to the user, leaving room for improvement in terms of comfort.

[0007] The above-mentioned comforter has a problem in that each piece of patch must be sewn to each of the horizontal and vertical bars, which is time-consuming. Furthermore, the above-mentioned comforter requires that the patch be sewn to each of the vertical and horizontal bars by hand. Therefore, it depends on the sewing skill of the person, and if an inexperienced seam sews, the stitching may come loose, causing the contents, such as feathers, to leak.

[0008] The present disclosure aims to provide a comforter that can be easily sewn while reducing fabric costs, reduces the possibility of contents leaking, and is comfortable to use. [Means for solving the problem]

[0009] The comforter according to the present disclosure comprises a first fabric portion extending in a first direction and a second direction intersecting the first direction, a second fabric portion overlapping the first fabric portion and extending in the first and second directions, a plurality of first gusset portions extending along the first direction and sewn to the first fabric portion and the second fabric portion, which divide the internal space formed between the first fabric portion and the second fabric portion into a plurality of regions, and a plurality of second gusset portions extending along the second direction and sewn to the first fabric portion and the second fabric portion, which divide the internal space into a plurality of regions. a second gusset portion extending from one end to the other end in a second direction of the comforter, a first end of the first gusset portion being sewn to the first fabric portion and the second fabric portion, a second end of the first gusset portion located opposite the first end of the first gusset portion being folded inside the region along the second gusset portion, and a nozzle for filling the region with contents is inserted between the second end and the second gusset portion, and the comforter has a two-layer structure in a region including the center in the first direction. The quilt has three or more second gusset portions lined up along the first direction, and of the three or more second gusset portions, a pair of second gusset portions located at both ends in the first direction are sewn to the first fabric portion and the second fabric portion, respectively, and a third gusset portion extends along the first direction between the pair of second gusset portions, and the third gusset portion divides the quilt into an upper and lower two-layer structure, and a first gusset portion is provided between the third gusset portion and the first fabric portion, and between the third gusset portion and the second fabric portion, and gaps are formed between some of the multiple first gusset portions and between the third gusset portion and the second gusset portion, and openings communicating with the gaps are formed at the ends of the gaps in the second direction.

[0010] The number of second gusset portions sewn into the first fabric portion may be greater than the number of second gusset portions sewn into the second fabric portion.

[0011] The quilt may have a single layer structure at each end in the first direction, and a two layer structure in the center in the first direction. [Effects of the Invention]

[0014] According to the present disclosure, the cost of fabric can be reduced and sewing can be easily performed, the possibility of contents leaking can be reduced, and the bag can be made more comfortable to use. [Brief explanation of the drawings]

[0016] Hereinafter, an embodiment of a comforter according to the present disclosure will be described with reference to the drawings. In the description of the drawings, identical or corresponding elements are designated by the same reference numerals, and duplicate explanations will be omitted as appropriate. In addition, for ease of understanding, some illustrations in the drawings may be simplified or exaggerated, and dimensional proportions and the like are not limited to those shown in the drawings.

[0017] FIG. 1 is a plan view showing a comforter 1 according to this embodiment. FIG. 2 is a cross-sectional view taken along line AA in FIG. 1. For example, the comforter 1 is a down comforter. The comforter 1 is, for example, rectangular in shape. The comforter 1 has a rectangular first fabric portion 2 and a rectangular second fabric portion 3 located on the back side of the first fabric portion 2. The first fabric portion 2 and the second fabric portion 3 are, for example, identical in shape and size to each other.

[0018] The first fabric portion 2 and the second fabric portion 3 extend in a first direction D1 and a second direction D2 that intersects with the first direction D1. The first direction D1 is, for example, the width direction (short direction) of the comforter 1, and the second direction D2 is the longitudinal direction of the comforter 1. For example, the first direction D1 and the second direction D2 are perpendicular to each other.

[0019] Various materials such as cotton, polyester, rayon, or lyocell can be used for the first fabric portion 2 and the second fabric portion 3. The first fabric portion 2 has an outer edge 2A that includes two short sides 2b and two long sides 2c. The second fabric portion 3 similarly has an outer edge 3A that includes a short side 3b and a long side 3c.

[0020] The short side 2b of the first fabric portion 2 and the short side 3b of the second fabric portion 3 are aligned, and the long side 2c of the first fabric portion 2 and the long side 3c of the second fabric portion 3 are aligned, thereby overlapping the outer edge 2A of the first fabric portion 2 and the outer edge 3A of the second fabric portion 3. The outer edges 2A and 3A are sewn together in a state where they are overlapped, thereby connecting the first fabric portion 2 and the second fabric portion 3.

[0021] The comforter 1 comprises a plurality of first gusset sections 4 that extend in a first direction D1 and partition an internal space S formed by the first fabric section 2 and the second fabric section 3, and a second gusset section 5 that extends in a second direction D2 and partitions the internal space S. The first gusset sections 4 and the second gusset sections 5 are three-dimensional quilts that have a width in a third direction D3 that is perpendicular to both the first direction D1 and the second direction D2. The third direction D3 is, for example, the vertical direction.

[0022] The first gusset portion 4 and the second gusset portion 5 may be made of the same material. The first gusset portion 4 and the second gusset portion 5 are made of, for example, a fabric that is harder than the first fabric portion 2 and the second fabric portion 3. This more reliably prevents the first gusset portion 4 and the second gusset portion 5 from setting. The first gusset portion 4 and the second gusset portion 5 may also be made of different materials.

[0023] The material of the first gusset portion 4 and the second gusset portion 5 may be, for example, polyester. In this case, the cost of the first gusset portion 4 and the second gusset portion 5 can be reduced and the strength of the first gusset portion 4 and the second gusset portion 5 can be increased. However, the material of the first gusset portion 4 and the second gusset portion 5 may be a material other than polyester, such as cotton, rayon, or cupra, and can be changed as appropriate. Furthermore, the material of the first gusset portion 4 and the second gusset portion 5 may be a blend of multiple materials, such as a blend of polyester and cotton.

[0024] Fig. 3 is a plan view of the duvet 1, showing schematically the arrangement of the first gusset section 4 and the second gusset section 5 in the duvet 1. As shown in Figs. 2 and 3, the first gusset section 4 and the second gusset section 5 divide the internal space S into a plurality of areas A. The areas A correspond to compartments divided by the first gusset section 4 and the second gusset section 5. The shape of the areas A in plan view is, for example, rectangular.

[0025] The number of areas A formed by the first gusset section 4 and the second gusset section 5 is, for example, 20 (5 x 4). Areas A contain contents B. Contents B are made of, for example, a flexible material. One example of contents B is feathers. However, contents B may also be, for example, wadding, and the type of contents B is not particularly limited.

[0026] Sets C of multiple first gusset portions 4 extending in the first direction D1 are lined up along the second direction D2, and the number of sets C lined up along the second direction D2 is, for example, four. However, the number of sets C may be one or more and three or less, or five or more, and is not particularly limited. The second gusset portion 5 extends from one end to the other end in the second direction D2. In other words, the second gusset portion 5 extends from the short sides 2b, 3b at one end side in the second direction D2 to the short sides 2b, 3b at the other end side in the second direction D2.

[0027] For example, the comforter 1 has a plurality of second gusset portions 5, which are arranged along the first direction D1. As an example, the number of second gusset portions 5 is three. However, the number of second gusset portions 5 may be one, two, four or more, and is not particularly limited. The second gusset portion 5 has an upper side portion 5b sewn into the first fabric portion 2 and a lower side portion 5c sewn into the second fabric portion 3.

[0028] The second gusset portion 5 is sewn to the first fabric portion 2 at the upper edge portion 5b, and is sewn to the second fabric portion 3 at the lower edge portion 5c. Like the second gusset portion 5, the first gusset portion 4 also has an upper edge portion sewn to the first fabric portion 2 and a lower edge portion sewn to the second fabric portion 3.

[0029] The comforter 1 has, for example, a plurality of first gusset portions 4 aligned along the first direction D1. The first gusset portions 4 include a first gusset portion 4A extending from the long sides 2c, 3c and a first gusset portion 4B extending in the first direction D1 between two second gusset portions 5 aligned along the first direction D1. The first gusset portions 4A and 4B have, for example, the same configuration. Therefore, hereinafter, unless there is a need to particularly distinguish between them, the first gusset portions 4A and 4B may be collectively referred to as the first gusset portion 4.

[0030] The first gusset portion 4A has a first end portion 4b sewn to the long sides 2c, 3c, and a second end portion 4c located opposite the first end portion 4b and folded along the second gusset portion 5 toward the inside of region A. The length of the first gusset portion 4A (the length of the first gusset portion 4A in a plan view) is longer than the distance K1 from the long sides 2c, 3c to the second gusset portion 5. The excess portion of the first gusset portion 4A extending from the long sides 2c, 3c is folded toward the inside of region A as the second end portion 4c.

[0031] A gap M1 is formed between the second end 4c of the first gusset portion 4A and the second gusset portion 5. The gap M1 is a passage into which a nozzle N for filling the region A with the contents B is inserted. The nozzle N is, for example, cylindrical. The contents B are sprayed from the nozzle N, and the contents B are sprayed into the region A from the nozzle N, thereby filling the region A with the contents B. The nozzle N is made of metal, for example. However, the nozzle N may be made of resin, for example, and the material of the nozzle N is not particularly limited.

[0032] An opening 8 is formed on each of the short sides 2b and 3b of the comforter 1 to allow the nozzle N to be inserted into region A located at the end in the second direction D2. The opening 8 may be, for example, a hole formed during the manufacturing process of the comforter 1, or may be closed after the filling of the contents B into region A is complete. The nozzle N inserted through the opening 8 into region A at one end in the second direction D2 can also be inserted into region A located further back in the second direction D2 than region A.

[0033] 4 is an enlarged perspective view of the first gusset portion 4B and the second gusset portion 5. As shown in FIGS. 3 and 4, the first gusset portion 4B has a first end portion 4d sewn to the second gusset portion 5 and a second end portion 4f folded inside the region A along the second gusset portion 5. The length of the first gusset portion 4B (the length of the first gusset portion 4B in a plan view) is longer than the distance K2 between the two second gusset portions 5 aligned along the first direction D1. The excess portion of the first gusset portion 4B extending from the portion sewn to the second gusset portion 5 is folded inside the region A as the second end portion 4f.

[0034] A gap M2 is formed between the second end 4f of the first gusset portion 4B and the second gusset portion 5. Similar to the gap M1 described above, the gap M2 is a passage through which the nozzle N is inserted. The second end 4f has, for example, an upper edge portion 4g that is sewn into the first fabric portion 2 and a lower edge portion 4h that is sewn into the second fabric portion 3. As an example, the gap M2 is formed between the upper edge portion 4g and the lower edge portion 4h. By passing the nozzle N through this gap M2 in the second direction D2 (for example, passing it through along the arrow in FIG. 4), the nozzle N can be inserted into region A and the contents B can be filled into region A from the nozzle N.

[0035] For example, gaps M1 and M2 are formed to sandwich some of the second gusset portions 5, and a pair of first gusset portions 4 (first gusset portion 4A and first gusset portion 4B) is sewn into the remaining parts of the second gusset portions 5. That is, second gusset portions 5 that form gaps M1 and M2 with the first gusset portions 4 and second gusset portions 5 that do not form gaps M1 and M2 with the first gusset portions 4 are lined up (e.g., alternately) along the first direction D1.

[0036] Figure 5 is an enlarged plan view of the corners (four corners) of the comforter 1. As shown in Figures 1 and 5, the comforter 1 has first cords 6 for connecting other bedding to the comforter 1. The first cords 6 extend in a direction oblique to both the first direction D1 and the second direction D2. One end of the first cords 6 is sewn into the short sides 2b and 3b, and the other end of the first cords 6 is sewn into the long sides 2c and 3c.

[0037] The material of the first string 6 may be the same as or different from the material of the first gusset portion 4 (or the second gusset portion 5), for example. The first string 6 may be a non-stretchable string or a stretchable rubber string. In this way, various materials can be used for the first string 6.

[0038] The comforter 1 may have, for example, second strings 7 for connecting other bedding to the comforter 1. The comforter 1 has, for example, multiple second strings 7, each sewn to the short sides 2b, 3b and the long sides 2c, 3c. As an example, the second strings 7 are provided in the center of the short sides 2b, 3b in the first direction D1, or in the center of the long sides 2c, 3c in the second direction D2. The second strings 7 are loop-shaped, and it is possible to connect other bedding to the comforter 1 by tying the string of the other bedding to the second strings 7.

[0039] Next, an example of a method for manufacturing the comforter 1 will be described. First, as shown in Figure 2, the first fabric portion 2 and the second fabric portion 3 are prepared (a step of preparing the first and second fabric portions). Then, the second gusset portion 5 is sewn onto the second fabric portion 3 (a step of sewing the second gusset portion to the second fabric portion). Specifically, the second gusset portion 5 is disposed on top of the second fabric portion 3 so as to extend in the second direction D2, and the lower edge portion 5c of the second gusset portion 5 is sewn to the second fabric portion 3 to fix the second gusset portion 5 to the second fabric portion 3.

[0040] 3, a plurality of first gusset portions 4 are prepared (a step of preparing first gusset portions). At this time, first gusset portions 4A are prepared that are longer than the distance K1 from the long sides 2c, 3c to the second gusset portions 5, and first gusset portions 4B are prepared that are longer than the distance K2 between two second gusset portions 5 arranged along the first direction D1.

[0041] Next, the lower side of the first end 4b of the first gusset portion 4A is fixed to the long side 3c by sewing (a step of fixing the first end of the first gusset portion), and the second end 4c of the first gusset portion 4A is folded inward of the region A so as to align with the second gusset portion 5 (a step of folding the second end of the first gusset portion). Then, the lower side of the folded second end 4c is fixed to the second fabric portion 3 by sewing (a step of fixing the second end).

[0042] Additionally, the first gusset portion 4B is disposed between the pair of second gusset portions 5. The lower side of the first end portion 4d of the first gusset portion 4B is fixed to the second gusset portion 5 by sewing (a step of fixing the first end portion to the second gusset portion), and the second end portion 4f of the first gusset portion 4B is folded inward of the region A so as to be aligned with the second gusset portion 5 (a step of folding the second end portion of the first gusset portion).

[0043] 3 and 4, the lower side 4h of the folded second end portion 4f is fixed to the second fabric portion 3 by sewing (step of fixing the second end portion). After the first gusset portion 4 and the second gusset portion 5 are fixed to the second fabric portion 3 as described above, the first gusset portion 4 and the second gusset portion 5 are each fixed to the first fabric portion 2.

[0044] Specifically, the first fabric portion 2 is placed over the first gusset portion 4 and the second gusset portion 5 (a step of placing the first fabric portion over the first and second gusset portions), and the upper edge portion of the first end portion 4b of the first gusset portion 4A is fixed to the first fabric portion 2 by sewing (a step of fixing the first end portion to the first fabric portion), and the upper edge portion of the second end portion 4c of the first gusset portion 4A is fixed to the first fabric portion 2 by sewing (a step of fixing the second end portion to the first fabric portion). Then, the upper edge portion of the first end portion 4d of the first gusset portion 4B is fixed to the first fabric portion 2 by sewing (a step of fixing the first end portion to the first fabric portion), and the upper edge portion 4g of the second end portion 4f of the first gusset portion 4B is fixed to the first fabric portion 2 by sewing (a step of fixing the second end portion to the first fabric portion 2).

[0045] Then, the short side 2b of the first fabric portion 2 and the short side 3b of the second fabric portion 3 are sewn together, and the long side 2c of the first fabric portion 2 and the long side 3c of the second fabric portion 3 are sewn together, thereby sewing the first fabric portion 2 to the second fabric portion 3 (step of sewing the first fabric portion to the second fabric portion). At this time, an opening 8 for inserting the nozzle N is formed in one of the pair of short sides 2b, 3b aligned along the second direction D2 (step of forming an opening for inserting the nozzle). The opening 8 is formed on the second direction D2 side of the second ends 4c, 4f of the first gusset portion 4.

[0046] Then, the nozzle N is inserted through the opening 8 to fill the region A with the contents B (a process of filling the region with the contents). At this time, for example, the nozzle N is inserted into the innermost region A, which is the furthest from the opening 8, and the contents B is filled from the innermost region A, and then the nozzle N is pulled out from the region A to fill the region A on the front side (the opening 8 side) of the region A with the contents B. In this way, the contents B are filled into each of the multiple regions A while the nozzle N is pulled out, and after filling the region A where the opening 8 is formed with the contents B has been completed, filling the multiple regions A lined up along the second direction D2 with the contents B is completed.

[0047] The contents B are filled in the multiple regions A arranged in the second direction D2 in the first direction D1. After all regions A have been filled with the contents B, the openings 8 are closed by sewing, completing the manufacture of the comforter 1. Note that while the contents B are being filled into the regions A, the filled contents B cause the second end 4f of the first gusset portion 4B (or the second end 4c of the first gusset portion 4A) to adhere tightly to the second gusset portion 5. Therefore, the folded second end 4f (second end 4c) adheres tightly to the second gusset portion 5, making it possible to reduce the gap M2 (gap M1) while filling the contents B.

[0048] Next, the effects obtained from the comforter 1 according to this embodiment will be described in more detail. In the comforter 1, a plurality of first gusset portions 4 extending in a first direction D1 and a plurality of second gusset portions 5 extending in a second direction D2 are arranged between the first fabric portion 2 and the second fabric portion 3. The internal space S of the comforter 1 formed between the first fabric portion 2 and the second fabric portion 3 is divided into a plurality of regions A by the plurality of first gusset portions 4 and the plurality of second gusset portions 5.

[0049] The second gusset portion 5 extends from one end to the other end in the second direction D2 of the comforter 1. A plurality of first gusset portions 4 are lined up along the first direction D1, and the second gusset portions 5 extend in the second direction D2 between the plurality of first gusset portions 4. The first gusset portions 4 have first end portions 4b, 4d at one end in the first direction D1, and the first end portions 4b, 4d are sewn to the first fabric portion 2 and the second fabric portion 3.

[0050] The first gusset portion 4 has second ends 4c, 4f at the other end in the first direction D1, and the second ends 4c, 4f are folded inside the region A along the second gusset portion 5. A nozzle N for filling the region A with the contents B is inserted between the second gusset portion 5 and the second ends 4c, 4f folded along the second gusset portion 5.

[0051] Therefore, the passage for inserting the nozzle N can be formed as gaps M1 and M2 without using the pressing cloth that was conventionally used, and since the pressing cloth is no longer necessary, the cost of the cloth can be reduced. Also, since the pressing cloth is no longer necessary, the user of the duvet 1 does not feel any discomfort due to the pressing cloth. As a result, the comfort of using the duvet 1 can be improved.

[0052] Since the first gusset portion 4 can be folded without using a patch to form the gaps M1 and M2 for the nozzle N passage, sewing can be easily performed. Furthermore, since the number of locations requiring sewing can be reduced compared to when a patch is used, the possibility of the stitching coming loose and the possibility of the contents B leaking can be reduced.

[0053] The second ends 4c, 4f may be movable in a direction away from the second gusset portion 5 and in a direction approaching the second gusset portion 5 (for example, in the first direction D1). In this case, the second ends 4c, 4f bent to the inside of the area A along the second gusset portion 5 are movable relative to the second gusset portion 5.

[0054] Therefore, by making it possible to vary the distance between the second gusset portion 5, which is the passage for the nozzle N, and the second ends 4c, 4f, it is possible to more reliably prevent the contents from being filled unevenly inside the area A. If the second ends 4c, 4f are made movable, it is possible to omit sewing the second ends 4c, 4f to the first fabric portion 2 and the second fabric portion 3.

[0055] In this embodiment, it is possible to omit sewing the upper edge portions (e.g., upper edge portion 4g) of the second end portions 4c, 4f to the first fabric portion 2 and sewing the lower edge portions (e.g., lower edge portion 4h) of the second end portions 4c, 4f to the second fabric portion 3. Furthermore, only the upper edge portions of the second end portions 4c, 4f may be sewn to the first fabric portion 2, or only the lower edge portions of the second end portions 4c, 4f may be sewn to the second fabric portion 3, or the second end portions 4c, 4f may not be sewn to either the first fabric portion 2 or the second fabric portion 3.

[0056] If the second ends 4c, 4f are movable relative to the second gusset portion 5, the second ends 4c, 4f can be freely moved within the region A. This reduces the amount of work required for sewing, making sewing easier. Furthermore, if the second ends 4c, 4f are movable relative to the second gusset portion 5, the second ends 4c, 4f can be more reliably moved to and tightly attached to the second gusset portion 5 when the contents B are being filled into the region A. This allows the second ends 4c, 4f to be more reliably tightly attached to the second gusset portion 5. As a result, uneven distribution of the contents B in the region A can be more reliably reduced, allowing the contents B to be evenly filled into the region A.

[0057] Next, a modified duvet 11 will be described with reference to Figures 6, 7, and 8. Note that some of the configuration of duvet 11 is the same as some of the configuration of duvet 1 described above, and therefore explanations of parts that overlap with those of duvet 1 will be omitted as appropriate, with the same reference numerals used for duvet 1. Duvet 11 has an upper surface 12 formed by a first fabric portion 2 and a lower surface 13 formed by a second fabric portion 3.

[0058] FIG. 6 is a bottom view showing the underside 13 of the comforter 11. FIG. 7 is a plan view showing the upper side 12 of the comforter 11. As shown in FIGS. 6 and 7, the number of second gusset sections 5 differs between the upper side 12 and the lower side 13. For example, the number of second gusset sections 5 sewn into the upper side 12 is greater than the number of second gusset sections 5 sewn into the lower side 13. As an example, four second gusset sections 5 are sewn into the upper side 12, while three second gusset sections 5 are sewn into the lower side 13. Like the comforter 1, the comforter 11 has a plurality of first strings 6 and a plurality of second strings 7. Note that the number and arrangement of the first strings 6 and second strings 7 are not limited to the examples in FIGS. 6 and 7 and can be changed as appropriate.

[0059] Figure 8 is a cross-sectional view taken along line BB in Figure 6. As shown in Figures 6 to 8, comforter 11 has a two-layer structure in the region including the center in first direction D1. That is, comforter 11 has a single-layer structure at each end in first direction D1, and a two-layer structure in the center in first direction D1. Comforter 11 has, for example, three or more second gusset sections 5 lined up along first direction D1.

[0060] Of the three or more second gusset portions 5 lined up along the first direction D1, a pair of second gusset portions 5 located at both ends in the first direction D1 are sewn into each of the first fabric portion 2 and the second fabric portion 3. A third gusset portion 14 extends along the first direction D1 between the pair of second gusset portions 5 located at both ends in the first direction D1, and the third gusset portion 14 divides the comforter 11 into two layers, an upper and a lower layer.

[0061] For example, some of the multiple second gusset portions 5 are sewn to the first fabric portion 2 and the third gusset portion 14. Also, some of the multiple second gusset portions 5 are sewn to the second fabric portion 3 and the third gusset portion 14. As an example, the comforter 11 includes two second gusset portions 5 sewn to the first fabric portion 2 and the third gusset portion 14, and one second gusset portion 5 sewn to the second fabric portion 3 and the third gusset portion 14.

[0062] Similar to the duvet 1, the duvet 11 has a plurality of first gusset portions 4A and a plurality of first gusset portions 4B. For example, a first gusset portion 4A is provided at each of one end and the other end in the first direction D1. A plurality of first gusset portions 4B are provided between two first gusset portions 4A lined up along the first direction D1. A first gusset portion 4B is provided between the third gusset portion 14 and the first fabric portion 2, and between the third gusset portion 14 and the second fabric portion 3.

[0063] The comforter 11 has a first gusset portion 4B sewn into the first fabric portion 2 and the third gusset portion 14, and a second gusset portion 4B sewn into the second fabric portion 3 and the third gusset portion 14. As described above, the first gusset portion 4A and the first gusset portion 4B each have first ends 4b, 4d and second ends 4c, 4f.

[0064] Gaps M3 are formed between some of the multiple first gusset portions 4B and between the third gusset portion 14 and the second gusset portion 5. Like the gaps M1 and M2 described above, gap M3 is formed by folding second ends 4c and 4f inward toward region A. Like gaps M1 and M2, openings 8 that communicate with gap M3 are formed at the ends of gap M3 in the second direction D2 (short sides 2b and 3b). In the comforter 11 described above, like the comforter 1 described above, contents B are filled into region A by inserting a nozzle N from the opening 8 into each region A through gaps M1, M2, and M3, and then filling each region A with contents B from the nozzle N.

[0065] As described above, in the comforter 11 according to the modified example, the first gusset portion 4 has second ends 4c, 4f, which are folded inside the area A along the second gusset portion 5. A nozzle N for filling the contents B into the area A is inserted between the second ends 4c, 4f and the second gusset portion 5.

[0066] Therefore, the passage through which the nozzle N is inserted can be formed as gaps M1, M2, M3 without using the aforementioned patch cloth, and since the patch cloth is unnecessary, the cost of the cloth can be reduced. Since the patch cloth is not necessary, the user of the duvet 1 does not feel any discomfort due to the patch cloth, sewing can be performed easily, and the comforter 1 can be made comfortable to use. Therefore, the duvet 11 can achieve the same effects as the duvet 1.

[0067] The above describes an embodiment of a comforter according to the present disclosure. However, the present disclosure is not limited to the above-described embodiment, and may be modified and used in other applications without departing from the spirit of the claims. In other words, the shape, size, number, material, and arrangement of each part of the comforter according to the present disclosure are not limited to the above-described embodiment, and may be modified as appropriate.

[0068] For example, in the above-described embodiment, the comforter 1, 11 was described as having a first string 6 and a second string 7. In the case of this comforter 1, 11, it is possible to connect other bedding to the comforter 1, 11 via the first string 6 or the second string 7. However, the comforter according to the present disclosure may be a comforter that does not have at least one of the first string 6 and the second string 7.

[0069] For example, in the above-described embodiment, an example was described in which the shape of region A in plan view is rectangular (a square shape with each angle being 90°). However, the shape of the region in plan view may be a shape other than a rectangle, and may be, for example, a polygon such as a triangle, parallelogram, rhombus, trapezoid, pentagon, hexagon (one example is a tortoiseshell shape), heptagon, or octagon, an ellipse, an oval, or a sector, and is not particularly limited.

[0070] The angle of each corner of region A does not have to be 90°, and may be an acute angle (less than 90°) or an obtuse angle (greater than 90°). However, from the viewpoint of efficiently drying the contents B contained in region A, it is desirable that the angle of each corner of region A be 90° or more (more preferably greater than 90°).

[0071] (Example) Next, examples of a comforter according to the present disclosure will be described. Note that the present invention is not limited to the following examples. As shown in FIG. 3, the comforter according to the examples includes a first fabric portion 2, a second fabric portion 3, a first gusset portion 4, and a second gusset portion 5, similar to the comforter 1 according to the above-described embodiment, and the first gusset portion 4 has second ends 4c, 4f folded along the second gusset portion 5. The warp threads (threads extending in the second direction D2) of the comforter according to the examples include at least one of TTC (Tetoron Tetoron Cotton), polyester, and cotton. The weft threads (threads extending in the first direction D1) of the comforter according to the examples are a cotton-polyester blend or polyester. The comforter according to the examples can be washed and dried in a washing machine at a coin laundry.

[0072] The comforters according to the examples include a comforter 1 in which the shape of region A in plan view is rectangular, and a comforter in which the shape of region A in plan view is hexagonal. These comforters were washed and dried at a coin laundry. A pre-wash and a main wash were performed at the coin laundry, with a final spin speed of 800 rpm. The final spin speed refers to the number of spin rotations per minute of a dry cleaning machine. As a result of washing and drying at the coin laundry as described above, it was found that regardless of whether the shape of region A in plan view was rectangular or hexagonal, washing and drying were possible without problems such as shrinkage. Furthermore, when the shape of region A in plan view was hexagonal, drying was more efficient than when the shape of region A in plan view was rectangular. This is thought to be because the obtuse angles (120°) of each corner of region A made it less likely for the contents to clog the corners. [Explanation of symbols]
