[0005] Patent Document 1: Japanese Patent Application Publication No. 2015-128587 Summary of the invention

[0006] Problem that the invention aims to solve

[0007] In the case of a wearable article having high stretchability formed of a knitted fabric or the like, for example, when the wearer attempts to expand the waist opening in a natural state to the left and right to put the legs in, the product may shrink in the up-down direction (become smaller in size in the up-down direction). In such a case, the up-down direction position of the joining area installed in the wearable article changes before and after the shrinkage, which causes the up-down direction position misalignment between the wearable article and the joining area provided in the absorbent pad, resulting in the risk of difficulty in joining the joining absorbent pad to the wearable article.

[0008] The present invention has been achieved in view of problems such as those described above, and an object of one aspect of the present invention is to provide a wearable article that easily engages an absorbent pad when a waist opening is expanded during wearing.

[0009] Solutions for solving problems

[0010] The main aspect of the present invention for achieving the above-mentioned object is a wearable article container, comprising: a wearable article having an up-down direction, a left-right direction, and a front-back direction intersecting each other, the wearable article having stretchability in the up-down direction and the left-right direction and to be used in combination with an absorbent pad; and a container member configured to contain the wearable article, the wearable article being reusable, the container member having a marking portion that reminds people that the wearable article is to be used in combination with the absorbent pad, the wearable article being made of a knitted fabric and having a pair of leg openings, the wearable article having a portion to be joined with the absorbent pad A joining area, the joining area is provided at least one position on each of the front side and the rear side in the front-to-rear direction of the wearable article, and with respect to the maximum length from the upper end of the joining area to the lower end of the wearable article, the pair of leg openings on at least one side of the front side and the rear side in the front-to-rear direction are formed so that when the area of ​​the wearable article on the upper side of the upper ends of the pair of leg openings is stretched to 200% in the left-to-right direction from a natural state, the maximum length is not shorter than the maximum length when the wearable article is in the natural state by twice or more the length of the joining area in the up-down direction.

DETAILED DESCRIPTION

[0025] At least the following matters are disclosed in the description of this specification and the drawings.

[0026] (Aspect 1)

[0027] A wearable article container, comprising: a wearable article having an up-down direction, a left-right direction, and a front-back direction intersecting each other, the wearable article having stretchability in the up-down direction and the left-right direction and to be used in combination with an absorbent pad; and a container member, which is configured to contain the wearable article, the wearable article can be reused, the container member having a marking portion that reminds people that the wearable article is to be used in combination with the absorbent pad, the wearable article being composed of a knitted fabric and having a pair of leg openings, the wearable article having a joining area to be joined with the absorbent pad, the joining area being configured to be reusable and having a pair of leg openings, the wearable article having a reusable portion ... The joining area is provided at at least one position on each of the front side and the rear side in the front-to-rear direction of the wearable article, and with respect to the maximum length from the upper end of the joining area to the lower end of the wearable article, the pair of leg openings on at least one side of the front side and the rear side in the front-to-rear direction are formed so that the maximum length when the area of ​​the wearable article above the upper ends of the pair of leg openings is stretched to 200% in the left-to-right direction from a natural state is not shorter than the maximum length when the wearable article is in the natural state by twice or more the length of the joining area in the up-down direction.

[0028] According to the wearable article housing body of aspect 1, even if the waist region is stretched in the left-right direction when the wearable article housed in the housing body is put on, contraction in the up-down direction is restricted in the region between the pair of leg openings, so that the length from the upper end of the joining region to the lower end of the wearable article is less likely to decrease. Therefore, in a state where the absorbent pad is inserted into the crotch of the wearable article, there is a high probability that there is a portion (engageable portion) where the joining region provided in the wearable article and the absorbent pad joining region provided in the absorbent pad overlap each other in the up-down direction. Therefore, a wearable article with which the absorbent pad can be easily joined and a housing body for the wearable article can be provided.

[0029] (Aspect 2)

[0030] A wearable article having an up-down direction, a left-right direction, and a front-back direction intersecting each other, the wearable article being composed of a knitted fabric, having stretchability in the up-down direction and the left-right direction, having a pair of leg openings, and being to be used in combination with an absorbent pad, the wearable article having a joining area to be joined with the absorbent pad, the joining area being provided at at least one position on each of the front and rear sides in the front-back direction of the wearable article, and with respect to the maximum length from the upper end of the joining area to the lower end of the wearable article, the pair of leg openings on at least one side of the front and rear sides in the front-back direction are formed so that when the area of ​​the wearable article on the upper side of the upper ends of the pair of leg openings is stretched to 200% from a natural state in the left-right direction, the maximum length is not shorter than the maximum length when the wearable article is in the natural state by twice or more the length of the joining area in the up-down direction.

[0031] According to the wearable article of aspect 2, even if the waist region is stretched in the left-right direction when the wearable article is put on, contraction in the up-down direction is restricted in the region between the pair of leg openings, so that the length from the upper end of the joining region to the lower end of the wearable article is less likely to be reduced. Therefore, in a state where the absorbent pad is inserted into the crotch of the wearable article, there is a high probability that there is a portion (engageable portion) where the joining region provided in the wearable article and the absorbent pad joining region provided in the absorbent pad overlap each other in the up-down direction. This can make it easier for the absorbent pad to be joined to the wearable article.

[0032] (Aspect 3)

[0033] A wearable article according to aspect 2, wherein, with respect to the maximum length from the upper end of the joining region to the lower end of the wearable article, the pair of leg openings on at least one side of the front and rear sides in the front-to-rear direction are formed so that the maximum length when the area of ​​the wearable article above the upper ends of the pair of leg openings is stretched to 200% in the left-right direction from the natural state is not shorter than the maximum length when the wearable article is in the natural state by the length of the joining region in the up-down direction or more.

[0034] According to the wearable article of aspect 3, the possibility of having a portion where the joining region of the wearable article and the joining region of the absorbent pad overlap each other in the up-down direction can be increased. This can make it easier to join the absorbent pad to the wearable article.

[0035] (Aspect 4)

[0036] The wearable article according to aspect 2 or 3, wherein in the natural state, the upper end of each of the leg openings is located on the upper side of the lower end at the center position in the left-right direction of the wearable article.

[0037] According to the wearable article of aspect 4, since the leg openings are formed obliquely, the ratio of the waist region formed on the upper side of the upper end of each leg opening to the wearable article becomes smaller in the vertical direction. In addition, since the width of the waist region that tends to shrink in the vertical direction is narrow, the shrinkage amount of the wearable article as a whole in the vertical direction becomes smaller compared to a wearable article having a boxer shorts shape or the like. Therefore, the joining area of ​​the wearable article is likely to overlap with the joining area of ​​the absorbent pad in the vertical direction, making it easier for the absorbent pad to be joined to the wearable article.

[0038] (Aspect 5)

[0039] The wearable article according to any one of aspects 2 to 4 includes a waist region which is located between the upper end of each leg opening and the upper end of the wearable article in the up-down direction, wherein the joining region is arranged in the waist region, and in the up-down direction, the upper end position of the joining region is located on the lower side of the central position of the waist region.

[0040] According to the wearable article of aspect 5, since the upper end of the joining region is located below the center of the waist region, the distance from the upper end of the joining region to the lower end of the wearable article is shorter than in the opposite case. This reduces the vertical positional displacement of the joining region caused by the vertical contraction of the wearable article, making it easier for the absorbent pad to be joined to the wearable article.

[0041] (Aspect 6)

[0042] The wearable article according to any one of aspects 2 to 5, wherein a force required to stretch the joining region per unit length in the up-down direction and the left-right direction is greater than a force required to stretch the knitted fabric per unit length in the up-down direction and the left-right direction.

[0043] According to aspect 6, when the wearable article is pulled in the left-right direction, the influence of the stretch in the area on the upper side of the joining region is less likely to extend to the area on the lower side of the joining region, and the shrinkage in the upper and lower directions in the area on the lower side is more likely to be suppressed. In addition, since the joining region itself is less likely to expand and contract in the upper and lower directions, the shrinkage in the upper and lower directions of the wearable article as a whole is more likely to be suppressed. This makes it less likely that positional misalignment of the joining region in the upper and lower directions occurs, and makes it easier for the absorbent pad to be joined to the wearable article.

[0044] (Aspect 7)

[0045] The wearable article according to any one of aspects 2 to 6 includes a crotch region located between the upper end of each leg opening and the lower end of the wearable article in the up-down direction and between the corresponding inner ends of the pair of leg openings in the left-right direction, wherein there is a portion where the crotch region and the joining region overlap each other in the left-right direction.

[0046] According to the wearable article of aspect 7, it is highly likely that the stretching of the crotch region in the left-right direction is suppressed in the portion overlapping with the joining region. Therefore, the contraction of the crotch region in the up-down direction is suppressed, making it less likely that the positional displacement of the joining region in the up-down direction will occur. This can make it easier to join the absorbent pad to the wearable article.

[0047] (Aspect 8)

[0048] The wearable article according to any one of aspects 2 to 7, wherein a stretch suppressing member having a prescribed length in the up-down direction is provided in the crotch region.

[0049] According to the wearable article of aspect 8, even when the wearable article is stretched in the left-right direction, the portion of the crotch region where the expansion and contraction restraining member is located is less likely to shrink in the up-down direction. This reduces the up-down positional displacement of the joining region, making it easier to join the absorbent pad to the wearable article.

[0050] (Aspect 9)

[0051] The wearable article according to any one of aspects 2 to 8, wherein the expansion and contraction suppressing member is continuous from the crotch region to an upper side of an upper end of the crotch region in the up-down direction.

[0052] According to the wearable article of aspect 9, it is possible to suppress shrinkage in the vertical direction over a wide range in the vertical direction (from the crotch region to the waist region). This reduces the vertical positional displacement of the joining region, making it easier to join the absorbent pad to the wearable article.

[0053] (Aspect 10)

[0054] The wearable article according to any one of aspects 2 to 9, wherein the stretch suppressing member includes a central stretch suppressing portion arranged in a central portion in the left-right direction.

[0055] According to the wearable article of aspect 10, excessive contraction of the left-right central portion is suppressed by providing the central expansion and contraction suppressing portion in the left-right central portion which is most likely to contract in the vertical direction. This reduces the vertical positional displacement of the joining region, making it easier to join the absorbent pad to the wearable article.

[0056] (Aspect 11)

[0057] The wearable article according to any one of aspects 2 to 10, wherein the stretch suppressing member includes a pair of side stretch suppressing portions respectively located on both sides of the central stretch suppressing portion in the left-right direction.

[0058] According to the wearable article of aspect 11, when an attempt is made to expand the wearable article in both left-right directions, it is highly likely that contraction in the up-down direction is suppressed in both left-right directions. Therefore, it becomes easier to suppress contraction in the up-down direction over a wide range in the left-right direction of the wearable article, so that the up-down positional misalignment of the joining region can be reduced. This can make it more likely that the absorbent pad can be joined to the wearable article.

[0059] (Aspect 12)

[0060] A wearable article according to any one of aspects 2 to 11, wherein each leg opening of the pair of leg openings comprises a cover seam along a peripheral edge thereof.

[0061] According to the wearable article of aspect 12, the covering seam increases the rigidity of the periphery of each leg opening, thereby weakening the stretchability of both sides of the crotch region. Therefore, both sides of the crotch region are less likely to shrink in the up-down direction, so that the up-down direction misalignment of the joining area can be reduced. This can make it more likely that the absorbent pad can be joined to the wearable article.

[0062] (Aspect 13)

[0063] According to the wearable article of any one of aspects 2 to 12, a crotch sewn portion having a prescribed length in the left-right direction is provided at the lower end portion in the up-down direction.

[0064] According to the wearable article of aspect 13, the crotch sewn portion increases the rigidity of the lower end of the crotch region and suppresses expansion and contraction in the left-right direction. Therefore, even when the wearable article is expanded in both left-right directions, the crotch region is unlikely to be stretched in the left-right direction, making it possible to suppress the contraction of the crotch region in the up-down direction. This reduces the up-down positional displacement of the joining region, making it easier for the absorbent pad to be joined to the wearable article.

[0065] (Aspect 14)

[0066] The wearable article according to any one of aspects 2 to 13, wherein there is a portion where the cover seam portion and the crotch seam portion cross each other.

[0067] According to the wearable article of aspect 14, the crotch sewing portion and the leg wrapping sewing portion are connected and function like a frame, increasing the rigidity of the lower end of the crotch region and both sides of the crotch region. This makes it easier to suppress excessive expansion and contraction of the crotch region as a whole. This reduces the positional misalignment of the joining region in the up-and-down direction, making it easier for the absorbent pad to be joined to the wearable article.

[0068] (Aspect 15)

[0069] The wearable article according to any one of aspects 2 to 14, wherein the stretch-reducing component does not include an elastic member.

[0070] According to the wearable article of aspect 15, at least in the natural state, the wearable article does not shrink in the vertical direction, so that when the wearable article is expanded in the left-right direction, it is possible to prevent the vertical shrinkage from becoming excessively large. This reduces the vertical positional displacement of the joining area, making it easier for the absorbent pad to join with the wearable article.

[0071] (Aspect 16)

[0072] A wearable article according to any one of aspects 2 to 15, wherein, with respect to the maximum length from the upper end of the joining region to the lower end of the wearable article, a force required to stretch an area of ​​the wearable article above the upper ends of the pair of leg openings in the left-right direction from the natural state by 200% to the maximum length of the wearable article in the natural state is 1 / 5 or less of a force required to stretch an area of ​​the wearable article above the upper ends of the pair of leg openings in the left-right direction from the natural state by 200%.

[0073] According to the wearable article of aspect 16, when the wearable article is extended in the left-right direction and the absorbent pad is inserted into the wearable article, even if the up-down dimension of the wearable article has been reduced, the up-down dimension of the wearable article can be easily restored to its original dimension by gently pushing the absorbent pad into the crotch side. This can make it easier to restore the length from the upper end of the joining area to the lower end of the wearable article to its original state compared to the opposite case. Therefore, it is less likely that the joining area of ​​the wearable article and the joining area of ​​the absorbent pad will be misaligned in the up-down direction, making it easier for the absorbent pad to be joined to the wearable article.

[0074] (Aspect 17)

[0075] A wearable article according to any one of aspects 2 to 16, wherein the fabric comprising the wearable article comprises at least 90% by weight polyester or polyethylene.

[0076] According to the wearable article of aspect 17, since polyester and polyethylene are materials having high elongation compared with cotton, the inclusion of a large amount of such materials can further promote elongation. In addition, polyester and polyethylene are materials having non-absorbent and fast dryability, thus improving the dryability of the wearable article.

[0077] (Aspect 18)

[0078] A wearable article according to any one of aspects 2 to 17, wherein the fabric constituting the wearable article does not contain any water-absorbent material.

[0079] According to the wearable article of aspect 18, by not including any water-absorbent material, the fabric is less likely to absorb water. Therefore, the time required for drying after washing can be reduced, thereby improving the dryability of the wearable article.

[0080] (Aspect 19)

[0081] A wearable article according to aspect 17 or 18, wherein the fabric comprising the wearable article comprises less than 10% by weight of a material having a higher stretchability than polyester or polyethylene.

[0082] According to the wearable article of aspect 19, since the fabric constituting the wearable article contains 90 weight % or more of polyester or polyethylene, the stretchability can be improved while ensuring good dryability by including the above-mentioned material with higher stretchability accounting for less than 10 weight % in the remaining part.

[0083] (Aspect 20)

[0084] A wearable article according to any one of aspects 2 to 19, wherein the fabric constituting the wearable article comprises a region comprising a material having a higher stretchability than polyester or polyethylene and a region not comprising said material.

[0085] According to the wearable article of aspect 20, by arranging the highly stretchable material in the area where fit is particularly required (i.e., by forming an area containing a material having a higher stretchability), the fit can be further improved in a limited area of ​​the wearable article, thereby improving functionality. Alternatively, in addition to improving the fit in a specific area, for example, by providing an area containing a material having a higher stretchability in a plurality of areas with spaces therebetween, the fit of the wearable article can also be improved over the entire wearable article.

[0086] (Aspect 21)

[0087] The wearable article according to any one of aspects 2 to 20, wherein the joining region is provided with a separate sheet member different from the knitted fabric constituting the main body portion, and the separate sheet member is composed of polyethylene or polyester.

[0088] According to the wearable article of aspect 21, since the separate sheet member is joined to the main body portion, the dryability of the wearable article is improved by making the separate sheet member of a material having quick dryability like the main body portion.

[0089] (Aspect 22)

[0090] A wearable article according to aspect 21, wherein the separate sheet member is joined to a fabric constituting the wearable article by sewing with a thread along a peripheral edge portion of the separate sheet member.

[0091] According to the wearable article of aspect 22, in the area inside the peripheral edge portion that has been sewn with thread, the fabric and the separate sheet member are not closely adhered (not joined) in the thickness direction, and a space is formed between the separate sheet member and the fabric. That is, the entire separate sheet member is not in a state of being joined to the fabric, and therefore, compared with the case where the entire sheet member is joined to the fabric, the surface of the separate sheet member that contacts the fabric has a wide area in contact with the air, which makes it easy for moisture to evaporate. Therefore, dryability is improved.

[0092] (Aspect 23)

[0093] The wearable article according to aspect 21 or 22, wherein when viewed in the thickness direction, there is a portion where the separate sheet member and the expansion and contraction suppressing portion overlap each other.

[0094] According to the wearable article of aspect 23, by providing the expansion and contraction suppressing portion, a change in contraction force occurs in the fabric constituting the wearable article, and a space is more likely to be formed between the skin side of the fabric and the non-skin side of the separate sheet member. By allowing air to easily escape from such a space, dryability is improved.

[0095] (Aspect 24)

[0096] The wearable article according to any one of aspects 21 to 23, wherein, regarding the size of the separate sheet member, the length in the up-down direction is 50 mm or less and the length in the left-right direction is 150 mm or less.

[0097] According to the wearable article of aspect 24, if the individual sheet members are too large, the sheet member portion may become difficult to dry, but by adjusting the size within the above range, it becomes easier to dry while ensuring an area that can maintain sufficient bonding force with the fabric.

[0098] (Aspect 25)

[0099] A wearable article according to any one of aspects 21 to 24, wherein the thickness of the separate sheet member is 3 mm or less.

[0100] According to the wearable article of aspect 25, since the sheet member is not too thick, it is possible to maintain easy drying while ensuring a thickness capable of maintaining sufficient bonding force with the fabric.

[0101] (Aspect 26)

[0102] A wearable article according to any one of aspects 2 to 25, wherein, when both side ends of the front waist region and the rear waist region of the wearable article in the left-right direction have been cut off and the wearable article has been unfolded in the up-down direction, the area of ​​region S1 is smaller than the area of ​​the remaining region S2, wherein the region S1 is an area between the upper end of the front joint region and the upper end of the rear joint region in the up-down direction and between the respective ends of the front joint region and the rear joint region that are most toward one side and the respective ends of the front joint region and the rear joint region that are most toward the other side in the left-right direction.

[0103] According to the wearable article of aspect 26, the region S1 in the fabric constituting the wearable article is the region covered by the absorbent pad when the absorbent pad is attached. Therefore, if drying is somewhat insufficient after washing the wearable article, or if the wearable article becomes wet after the absorbent pad is attached for some other reason, the region S1 is likely to have lower dryability thereafter because it is covered by the absorbent pad. However, by making the area of ​​the region S1 in the fabric constituting the wearable article smaller than the area of ​​the region S2, it is easier to suppress the deterioration of the dryability of the entire wearable article than in the opposite case.

[0104] (Aspect 27)

[0105] A wearable article according to any one of aspects 2 to 25, wherein, when both side ends of the front waist region and the rear waist region of the wearable article in the left-right direction have been cut off and the wearable article has been unfolded in the up-down direction, the area of ​​region S1 is larger than the area of ​​the remaining region S2, wherein the region S1 is an area between the upper end of the front joint region and the upper end of the rear joint region in the up-down direction and between the respective ends of the front joint region and the rear joint region that are most toward one side and the respective ends of the front joint region and the rear joint region that are most toward the other side in the left-right direction.

[0106] According to the wearable article of aspect 27, even if drying is somewhat insufficient after washing the wearable article, the region S1 will be covered by the absorbent pad, and therefore, the skin is less likely to get wet and wearing comfort is less likely to be impaired.

[0107] ===Implementation Method===

[0108] As an example of a wearable article according to an embodiment of the present invention, a pant-type wearable article 1 (hereinafter also simply referred to as "wearable article 1") of a type that can be used in combination with an absorbent pad 100 for absorbing excrement such as urine is attached to the inside of the wearable article.

[0109] <Basic Structure of Wearable Article 1>

[0110] Figure 1 is a schematic perspective view of a wearable article 1 according to this embodiment. Figure 1 In the underwear-type state shown, the wearable article 1 has an "up-down direction", "left-right direction" and "front-back direction" that are orthogonal to each other. In the up-down direction, in a state where the wearable article 1 is worn by a wearer, the "upper side (up)" refers to the side facing the waist of the wearer, and the "lower side (lower)" refers to the side facing the crotch area of ​​the wearer. In the front-back direction, in the worn state, the "front side" refers to the ventral side of the wearer, and the "back side" refers to the back side of the wearer. Each material (sheet member) constituting the wearable article 1 has a "thickness direction". In the thickness direction, in a state where the wearable article 1 is worn by a wearer, the "skin side" refers to the side closer to the wearer's skin, and the "non-skin side" refers to the side opposite to the skin side.

[0111] The wearable article 1 of the present embodiment is formed into a panty type, which includes a waist opening BH arranged on the upper side in the up-down direction and a pair of leg openings LH, LH arranged on the lower side in the up-down direction and respectively located on both sides in the left-right direction. The absorbent pad 100 can be detachably attached to the inner side of the panty type wearable article, and by changing the absorbent pad 100, the wearable article 1 itself can be reused (worn). For example, when urine or the like is excreted while the wearer (user) is wearing the wearable article 1 with the absorbent pad 100 attached, the absorbent pad 100 contaminated by absorbing the excrement can be removed from the wearable article 1 and replaced with a new absorbent pad 100, so that the wearable article 1 can be reused. In addition, the wearable article 1 can be washed and can therefore be used hygienically for a long period of time (such as 2 weeks or longer).

[0112] Figure 2 A is a plan view when the wearable article 1 in its natural state is viewed from the front side in the front-rear direction. Figure 2 B is a plan view when the wearable article 1 in its natural state is viewed from the rear side in the front-rear direction. In this article, the "natural state" refers to a state in which the wearable article 1 has been left for a predetermined time. For example, the wearable article 1 folded and packaged is taken out of its package, then gently unfolded so as not to cause deformation, and placed on a flat surface such as a table. The "natural state" refers to a state in which the wearable article 1 has been kept flat on a flat surface for 5 minutes, so that almost no wrinkles remain on the surface of the wearable article 1.

[0113] The wearable article 1 includes a main body 10, a stretch suppressing portion 20, and a joining region 30. The main body 10 is a portion constituting the outer cover of the wearable article 1, and is formed of a sheet member having stretchability. In the present embodiment, the sheet member forming the main body 10 is composed of a "woven fabric" or a "knitted fabric", and has stretchability in both the up-down direction and the left-right direction. Note that a "woven fabric" is a fabric having a planar structure by orthogonally interlacing wefts through a plurality of warps arranged in parallel, and examples thereof include a fabric called "cloth" (a type of woven fabric). In the case of a woven fabric, a woven fabric having stretchability can be formed by using a highly stretchable thread or by changing the thread density. On the other hand, a "knitted fabric" is a fabric having a planar structure by forming a loop with a thread and entangled the loop with other loops, and examples thereof include a fabric called "knitted fabric". Since a knitted fabric is made by entangled a plurality of loops, the fabric can be greatly stretched and contracted even with a small force by deforming the loops. An example of making the main body 10 (wearable article 1) by using a knitted fabric is described below.

[0114] The main body 10 is composed of a so-called circular knitted fabric knitted into a tubular shape in the up-down direction. A portion of the upper end portion of the tubular main body 10 is folded back from the upper side to the lower side in the up-down direction, thereby forming a waist folded back portion 11. The waist folded back portion 11 suppresses fabric wear at the upper end portion (i.e., the waist opening BH) of the circular knitted fabric. In addition, a thread that tends to be less stretchable than the threads in other parts is knitted into the waist folded back portion 11. This increases the contraction force along the periphery of the waist opening BH, and therefore, when the wearable article 1 is worn, the waist opening BH can be suppressed from sagging and the fit can be improved. Note that, instead of folding back the upper end portion of the circular knitted fabric, a separate sheet member can be stacked and joined to the upper end portion to apply a larger contraction force along the periphery of the waist opening BH.

[0115] On the other hand, at the lower end of the main body 10, a crotch sewn portion 12 is formed by sewing the front and rear sides of the circular knitted fabric together. By joining the lower end of the main body 10 with the crotch sewn portion 12, the tubular circular knitted fabric is formed into a panty type having a pair of leg openings LH, LH (see the description further below). Figure 3 In the present embodiment, the crotch seam portion 12 is located at the lowermost position of the wearable article 1 in the vertical direction (see Figure 2 A and Figure 2 B).

[0116] The pair of leg openings LH, LH are formed by cutting off a portion of the main body 10 (see Figure 3). A leg opening covering stitching portion 13 is formed in the peripheral portion of each leg opening LH, LH. The leg opening covering stitching portion 13 is formed by winding and sewing a thread around the edge of the knitted fabric along the peripheral edge of the leg opening LH. This helps to suppress fabric wear at the cut portion of the leg opening LH. In addition, by forming the leg opening covering stitching portion 13, the fit of the leg opening LH can be improved while wearing the wearable article, and the side leakage of excrement such as urine can be easily suppressed.

[0117] like Figure 2 A and Figure 2 As shown in FIG. 1B , in the up-down direction of the wearable article 1 in the natural state, the upper end of the leg opening LH is defined as LHt. The upper end LHt is located slightly inward from the outermost end in the left-right direction. Similarly, in the up-down direction of the wearable article 1 in the natural state, the lower end of the leg opening LH is defined as LHb. The lower end LHb is located at the lowermost position of the wearable article 1 in the up-down direction and at the innermost position of the leg opening LH in the left-right direction.

[0118] In the wearable article 1, a "crotch region CR" is defined as a region shown in hatching between the upper end LHt of the leg opening LH and the lower end LHb thereof (i.e., the lower end of the wearable article 1) in the up-down direction and between the respective lower ends LHb, LHb of a pair of leg openings LH in the left-right direction (i.e., between the respective inner ends of the leg openings LH). The crotch region CR is a region mainly located in the crotch region of the wearer (user) when the wearable article 1 is worn, and is also a region that holds at least a portion of the absorbent pad 100 when the absorbent pad 100 is attached. In addition, in the wearable article 1, a "waist region BR" is defined as a region located between the upper end LHt of the leg opening LH and the upper end of the wearable article 1 in the up-down direction. The waist region BR is a region mainly located in the waist (abdomen, buttocks, and hips) of the wearer (user) when the wearable article 1 is worn.

[0119] The stretch suppressing portion 20 is a portion having the function of a stretch suppressing component that is constructed to suppress the stretching of the wearable article 1 in the up-down direction. In the present embodiment, a plurality of stretch suppressing portions 20 are provided in predetermined positions of the main body portion 10 of the wearable article 1, and each stretch suppressing portion has a predetermined length in the up-down direction. More specifically, on the front side in the front-to-back direction of the wearable article 1 (main body portion 10), a front central stretch suppressing portion 21 is provided in the central portion in the left-to-right direction, and a pair of front side stretch suppressing portions 23, 23 (corresponding to the side stretch suppressing components) are provided on both sides in the left-to-right direction of the front central stretch suppressing portion 21, respectively (see Figure 2A). Similarly, on the rear side of the wearable article 1 (main body 10) in the front-to-rear direction, a rear central stretch-reduction portion 22 is provided in the central portion in the left-right direction, and a pair of rear side stretch-reduction portions 24, 24 (side stretch-reduction restraining members) are provided on both sides in the left-right direction of the rear central stretch-reduction restraining portion 22, respectively (see Figure 2 B).

[0120] When the wearable article 1 is to be put on by the wearer (user), the following action is performed: the wearer's legs are passed through the pair of leg openings LH, and then the waist region BR is grasped and the wearable article is pulled up to the crotch region. As described above, the main body 10 is formed of a knitted fabric (or woven fabric) having stretchability. Therefore, during the action of pulling up the wearable article 1, if the main body 10 is excessively stretched in the up-down direction, it may be difficult to pull up the wearable article 1. In contrast, in the wearable article 1 of the present embodiment, the portion where the stretch suppressing portion 20 is provided suppresses the stretching (stretching) of the main body 10 in the up-down direction, and therefore, the wearable article 1 can be easily pulled up.

[0121] The stretch suppressing portion 20 (stretch suppressing member) is implemented by applying a treatment to the knitted fabric constituting the main body portion 10 to reduce the stretchability of the knitted fabric in the up-down direction. For example, by applying a treatment of sewing (or "stitching") a thread having low stretchability into a predetermined area of ​​the knitted fabric constituting the main body portion 10, the stretchability in the up-down direction can be reduced. Alternatively, during knitting of the knitted fabric, the stretchability in a portion of the knitted fabric can be reduced by changing the knitting pattern in a predetermined portion or by changing the stretchability of the thread. In addition to the above, the stretchability can be reduced by applying a compression treatment (embossing, etc.) to a predetermined portion within the knitted fabric.

[0122] The bonding area 30 is an area to which the absorbent pad 100 can be detachably attached to the wearable article 1 and is provided on the skin side of the main body portion 10 in the thickness direction. In the present embodiment, the rectangular front bonding area 31 is provided on the skin side of the waist region BR located on the front side in the front-back direction (see FIG. Figure 2 A), and the rectangular rear side joining area 32 is provided on the skin side of the waist region BR on the rear side in the front-rear direction.

[0123] By respectively connecting the bonding areas 30 disposed on the wearable article 1 to the absorbent pad bonding areas 120 disposed on the absorbent pad 100 (see further description below), Figure 4) is joined, the absorbent pad 100 can be attached to and held on the inner side (skin side) of the wearable article 1. In addition, the joining area 30 serves as a reference (i.e., a guide) when the user attaches the absorbent pad 100 to the wearable article 1; by visually confirming the joining area 30, the user can attach the absorbent pad 100 in the correct position of the wearable article 1.

[0124] In the present embodiment, it is preferred that the joining area 30 is provided with a separate sheet member different from the knitted fabric constituting the main body 10. For example, as a separate sheet member, a known hook and loop fastener having a plurality of engaging protrusions (male material, hooks) or engaged protrusions (female material, loops) provided on the surface of the substrate can be used. In order to improve visibility, it is more preferred that the color of the hook and loop fastener is different from the color of the knitted fabric constituting the main body 10. However, it is not necessary to provide a separate sheet member as the joining area 30, as long as an area to which the absorbent pad joining area 120 can be detachably joined is formed in the skin side of the wearable article 1. For example, if the knitted fabric constituting the main body 10 itself can be detachably joined to the absorbent pad joining area 120, the joining area 30 can be formed by printing a specific area on the skin side of the main body 10 with ink of a different color from that of the main body 10.

[0125] An overview of a method for manufacturing the wearable article 1 is described below. Figure 3 A to Figure 3 C is a diagram illustrating a method for manufacturing the wearable article 1 . Figure 3 An example in which the wearable article 1 is formed by the aforementioned “knitted fabric” is illustrated.

[0126] First, if Figure 3 As shown in FIG. 1A , the tubular knitted fabric 10A (so-called “circular knitted fabric”) is made by knitting yarn in a circular pattern. At this time, the expansion and contraction suppressing portion 20 (21 to 24) is also arranged along the direction of the central axis of the tubular circular knitted fabric 10A (corresponding to the central axis of the tubular circular knitted fabric 10A). Figure 1 As described above, the stretch suppressing portion 20 is formed by applying a process such as changing the knitting pattern or sewing in a different thread. However, it is noted that the stretch suppressing portion 20 may be formed in the same manner as the circular knitted fabric 10A ( Figure 3 For example, after the circular knitted fabric 10A is formed, a process of separately forming the stretch suppressing portion 20 (stretch suppressing member) may be performed.

[0127] Next, the circular knitted fabric 10A is cut at a predetermined position in the up-down direction (axial direction) to cut out the main body portion 10 constituting the individual wearable articles 1, as shown in FIG. Figure 3 B. In this example, the circular knitted fabric 10A is located at positions C1 and C2 in the up-down direction (see Figure 3A). The cutting position C1 is the upper side of the main body 10 in the vertical direction, and the cutting position C2 is the lower side of the main body 10 in the vertical direction. In addition, the portion that becomes the leg opening LH is also cut out from the main body 10. Figure 3 In B, both left-right side portions are cut obliquely at the lower end portion of the tubular body portion 10 to form a pair of leg openings LH, LH.

[0128] Next, if Figure 3 As shown in C, the upper end portion of the tubular main body portion 10 in the up-down direction is folded back to form a waist folded portion 11. In addition, at the lower end portion of the tubular main body portion 10 in the up-down direction, the front lower edge 12f and the rear lower edge 12b are sewn together from front to back to form a crotch sewing portion 12. In this way, the tubular main body portion 10 is formed into an underpants type. Then, covering stitching is performed along the periphery of the corresponding leg opening LH that has been cut out to form a leg opening covering stitching portion 13. Finally, a separate sheet member (for example, a hook and loop fastener) or the like is attached to the inner side (skin side) of the main body portion 10 to form a joining area 30 (31, 32). In this way, a panty-shaped ... Figure 1 and Figure 2 The wearable article 1 is shown. Note that the implementation may vary Figure 3 C shows the order of processing.

[0129] <Stretchability of wearable article 1>

[0130] The wearable article 1 has been described above as having stretchability in the up-down direction and the left-right direction. More specifically, the wearable article is defined as having stretchability when the sample piece cut out from the knitted fabric constituting the main body portion 10 satisfies the following conditions when subjected to a tensile test. That is, the wearable article is defined as having stretchability when the maximum value of the elongation when the 50 mm×200 mm sample piece is pulled at a force of 5 N in each of the up-down direction and the left-right direction is 200% or more.

[0131] For example, the tensile test can be performed as follows. First, a rectangular sample piece 220 mm long in the up-down direction and 50 mm long in the left-right direction is cut out from the main body 10 of the wearable article 1. Note that in the 220 mm length, the 10 mm worth of portions at both ends of the sample piece in the up-down direction are the edges to be clamped by the chuck of the tensile tester. In addition, when the sample piece is cut out, it is preferred that the telescopic suppression portion 20 and the joining area 30 are not included. Next, 10 mm of each of the two ends in the up-down direction of the cut sample piece is clamped with the chuck of a known tensile tester (e.g., a universal material testing system from Instron). At this time, the chuck-to-chuck distance G0 of the tensile tester is set to 200 mm. From this state, the sample piece is pulled and stretched at a tensile rate of about 200 mm / min in the direction in which the chuck-to-chuck distance increases, and when the tensile force (magnitude of force) of the tensile test reaches 5 N, the chuck-to-chuck distance G1 (mm) is measured. Then, the value of the length of the sample piece after being pulled and the length of the sample piece before being pulled (= G1 / G0) is calculated and recorded as the elongation. This test is repeated multiple times to find the maximum value of the elongation (G1 / G0). According to the result, in the case where the maximum value of the elongation (G1 / G0) is 200% or more, it is found that the fabric constituting the wearable article 1 (main body 10) has stretchability in the up-down direction. Note that the size of the clamping edge for the chuck can be appropriately changed.

[0132] Similarly, a rectangular sample piece 220 mm long in the left-right direction and 50 mm long in the up-down direction was cut out from the main body 10 of the wearable article 1, and the left-right tensile test was performed according to the above process. In the case where the elongation is 200% or more, it is found that the fabric constituting the wearable article 1 (main body 10) has stretchability in the left-right direction. Note that in the case where a sample piece long in the left-right direction is cut out from the wearable article 1, the stretch suppressing portion 20 may be included. This is because the stretch suppressing portion 20 mainly plays a role in reducing the stretchability in the up-down direction and does not significantly affect the measurement of the stretchability in the left-right direction.

[0133] <Basic Structure of Absorbent Pad 100>

[0134] Figure 4A plan view and a cross-sectional view of an absorbent pad 100 are shown. The absorbent pad 100 has a substantially rectangular plan view shape, and has a longitudinal direction, a width direction, and a thickness direction that are orthogonal to each other. The longitudinal direction is a direction along the up-and-down direction (and the front-to-back direction) of the wearable article 1 when the absorbent pad is attached to the wearable article 1. The transverse direction is a direction along the left-right direction of the wearable article 1 when the absorbent pad is attached to the wearable article 1. The front side in the longitudinal direction is a side that is located on the ventral side of the wearer (the front side of the wearable article 1 in the front-to-back direction) when the absorbent pad 100 is attached to the wearable article 1. The rear side in the longitudinal direction is a side that is located on the back side of the wearer (the rear side of the wearable article 1 in the front-to-back direction) when the absorbent pad 100 is attached to the wearable article 1.

[0135] The absorbent pad 100 includes an absorbent body 110, a top sheet 111 disposed on the skin side of the absorbent body 110, a back sheet 112 disposed on the non-skin side of the absorbent body 110, and a pair of side sheets 115, 115 disposed more toward the skin side than the top sheet 111 and disposed on both sides in the left-right direction. The absorbent pad also includes an absorbent pad bonding area 120 to be bonded to the bonding area 30 of the wearable article 1.

[0136] The absorbent body 110 includes a polymer absorbent (superabsorbent polymer; also referred to as "SAP") and liquid absorbent fibers such as pulp fibers, and in this embodiment, Figure 4 As shown by the dotted line in , the absorbent body 110 has a substantially hourglass shape in which the central portion in the longitudinal direction narrows inwardly in the left-right direction. The liquid-absorbent fibers containing SAP may be covered by a liquid-permeable core wrapping sheet (not shown). In addition, the configuration of the absorbent body 110 is not limited to the above, and other examples may include an SAP sheet in which a SAP layer is attached to a hydrophilic sheet and an air-laid sheet in which liquid-absorbent fibers are formed into a sheet by an air-laid method.

[0137] The top sheet 111 is a liquid permeable sheet member arranged on the skin side of the absorbent body 110, and is a member that directly contacts the skin and / or excretion port of the wearer during use of the absorbent pad 100. Therefore, it is preferred that the top sheet 111 is a sheet member that is as soft as possible and has a soft-touch texture. Examples of sheet members constituting the top sheet 111 of the present embodiment may include breathable nonwoven fabrics, etc. In addition, a second sheet ( 200 ) that is substantially as liquid permeable as the top sheet 111 may be provided between the absorbent body 110 and the top sheet 111 in the thickness direction. Figure 4 not shown).

[0138] The back sheet 112 is a sheet member that is arranged in the thickness direction of the absorbent pad 100 to be liquid-impermeable but air-permeable toward the non-skin side more than the absorbent body 110. By providing the back sheet 112, the excretion liquid such as urine absorbed by the absorbent pad 100 is suppressed from penetrating to the non-skin side in the thickness direction. Therefore, when the absorbent pad 100 is used by being attached to the skin side of the wearable article 1, the excretion liquid such as urine absorbed by the absorbent pad 100 can be suppressed from penetrating to the wearable article 1 located on the non-skin side. Examples of the sheet member constituting the back sheet 112 of the present embodiment may include a resin film made of polyethylene, polypropylene, etc.

[0139] The side sheets 115 are members constituting both side portions in the transverse direction on the skin side of the absorbent pad 100. The side sheets 115 are also very likely to come into direct contact with the skin of the wearer during use of the absorbent pad 100, and therefore are preferably constituted by a sheet member that is as soft as possible like the top sheet 111. Examples of the sheet member constituting the side sheets 115 of the present embodiment may include breathable nonwoven fabrics and the like.

[0140] In the transverse direction inner end portion of each of the pair of side panels 115, 115, an absorbent pad elastic member 116 such as an elastic thread is provided in a stretched state along the longitudinal direction. The transverse direction inner end of each side panel 115 is folded back toward the transverse direction outer side, such as along Figure 4 As shown in the cross-sectional view taken at section AA of FIG. 1 , the absorbent pad elastic member 116 is attached in a manner sandwiched between the folded portions. During use of the absorbent pad 100, the elasticity exerted by the absorbent pad elastic member 116 causes the corresponding inner ends of the pair of side sheets 115, 115 to stand up toward the skin side in the thickness direction, thereby enabling the side sheets to act as leakage-proof walls (three-dimensional gathers) and thus suppressing side leakage of urine or the like.

[0141] The absorbent pad joining area 120 is provided on the non-skin side of the back sheet 112, and is a portion that is detachably joined to the joining area 30 on the wearable article 1, respectively, and includes: a front side absorbent pad joining area 121, which is arranged at the front side end in the longitudinal direction; and a rear side absorbent pad joining area 122, which is arranged at the rear side end in the longitudinal direction. The absorbent pad joining area 120 is provided with, for example, a sheet member (e.g., a hook and loop fastener) corresponding to the joining area 30 of the wearable article 1. For the same reason as the joining area 30, it is preferred that the color of the absorbent pad joining area 120 is different from the color of the back sheet 112 so that the user can easily visually identify the joining position.

[0142] When the absorbent pad 100 is used by being attached to the wearable article 1, the absorbent pad 100 is folded in half at the central position CL in the longitudinal direction of the absorbent pad 100 in such a manner that the skin side of the absorbent pad is located inside. The folded absorbent pad 100 is then inserted from the upper side of the waist opening BH of the wearable article 1, and the position is adjusted so that the central position CL in the longitudinal direction of the absorbent pad 100 is located at the lowermost end portion (the position overlapping the crotch sewing portion 12) of the wearable article 1. In this state, the front absorbent pad joining area 121 is joined to the front joining area 31 of the wearable article 1, and the rear absorbent pad joining area 122 is joined to the rear joining area 32 of the wearable article 1. Note that since the position of each absorbent pad joining area 120 in the longitudinal direction (up and down direction) is pre-adjusted so that it overlaps with the joining area 30 of the wearable article 1 in the state where the absorbent pad 100 has been inserted inside the wearable article 1, the joining areas 30 can be easily joined to each other. In this way, the absorbent pad 100 can be correctly attached to the wearable article 1.

[0143] <Action for putting on the wearable article 1 when the absorbent pad 100 is used in combination>

[0144] Next, a specific action for putting on the wearable article 1 when the absorbent pad 100 is used in combination will be described.

[0145] First, as a comparative example, an action for wearing the conventional wearable article 200 in a state where the absorbent pad 300 is used in combination will be described. Figure 5 is a schematic plan view of a conventional wearable article 200 (comparative example). Figure 6 A to Figure 6 C is a diagram illustrating a method for putting on the wearable article 200 when the wearable article 200 is used in combination with the absorbent pad 300.

[0146] Figure 5 The wearable article 200 of the comparative example shown is a panty-type wearable article having a waist opening BH and a pair of leg openings LH, LH and having a certain degree of stretchability, but unlike the wearable article 1 of the present embodiment, the panty-type wearable article has a so-called boxer shorts shape, in which the leg openings 1LH, LH protrude below the crotch (the lower end at the center position in the left-right direction of the wearable article 200). In addition, the wearable article 200 does not have a component equivalent to the stretch-reduction suppressing portion 20 and the joining region 30 of the wearable article 1. In addition, the absorbent pad 300 has the same shape as the reference Figure 4 The illustrated absorbent pad 100 is of substantially the same construction, but does not have an area equivalent to the absorbent pad engagement area 120 .

[0147] In the comparative example, when the wearable article 200 is used in combination with the absorbent pad 300, first, as shown in FIG. Figure 6As shown in FIG. 2A , with the absorbent pad 300 placed around the crotch region of the wearer, the legs of the wearer are respectively passed through the leg openings LH, LH of the wearable article 200 and then pulled up to just above the knees.

[0148] Next, if Figure 6 As shown in FIG. 2B , while holding the absorbent pad 300 with one hand to prevent it from slipping off the body, the wearable article 200 is pulled upward by grasping it with the other hand. Figure 5 The illustrated boxer shorts are shaped so that friction occurs between the leg openings LH protruding from the lower side and the wearer's legs, so that the leg openings LH (the hem of the pants) are easily caught on the wearer's legs. Figure 6 As shown in FIG. 2B , the pulled portion is significantly stretched in the up-down direction, making it difficult to pull the entire wearable article 200 up to the crotch region with one hand. Therefore, while changing the hand used to pull up the wearable article 200 and changing the position of pulling the wearable article 200 as appropriate, it is necessary to take time to pull the wearable article 200 up to the crotch region, which causes a problem of wearability. In addition, during the process of putting on the wearable article 200, both hands are occupied, making it difficult for the wearer to support himself by holding on to a wall, a chair, etc., so sufficient care must be taken to ensure safety.

[0149] After the wearable article 200 is pulled up to the crotch area of ​​the wearer, an operation is performed to adjust the position of the wearable article 200 and the absorbent pad 300 to fit snugly around the crotch area, such as Figure 6 C. At this time, when the wearable article 200 is pulled front and back, left and right, or up and down, the position of the absorbent pad 300 may be displaced. For example, if the wearable article 200 is pulled diagonally upward to adjust its position, the absorbent pad 300 will also tend to be displaced in the same direction. In this case, the absorbent pad 300 must be pulled in the opposite direction and the position readjusted, but pulling the front side will cause the rear side to be displaced, making it difficult to fit the absorbent pad 300 to the appropriate position in the crotch area.

[0150] Although it is conceivable that a third party such as a caregiver can assist in putting on the wearable article 200 and the absorbent pad 300, this may place a heavy mental burden on the wearer or the third party, so it is desirable that the wearer can easily put them on by themselves.

[0151] Next, an operation for wearing the wearable article 1 of the present embodiment in a state where the absorbent pad 100 is used in combination will be described. Figure 7 A to Figure 7 C is a diagram illustrating a method for putting on the wearable article 1 when the wearable article 1 is used in combination with the absorbent pad 100 .

[0152] In this embodiment, first, the absorbent pad 100 is attached to the wearable article 1. As described above, the absorbent pad 100 is attached by engaging the absorbent pad engagement region 120 of the absorbent pad 100 with the engagement region 30 of the wearable article 1. Then, as shown in FIG. Figure 7 As shown in FIG. 1A , in this state where the absorbent pad 100 is attached, the wearer's legs are respectively passed through the leg openings LH, LH of the wearable article 1 and then the wearable article 1 is pulled up to just above the knees.

[0153] Next, the wearable article 1 is pulled upward by grasping the waist region BR of the wearable article 1. Figure 7 In B, the wearer uses both hands to pull up the wearable article by grasping both sides of the waist region BR in the left and right directions. In this embodiment, the absorbent pad 100 is attached to the wearable article 1 in advance, so there is no need to Figure 6 B. Therefore, the wearable article 1 can be pulled up with both hands or with one hand supporting the body. In addition, since the leg openings of the wearable article 1 are beveled, the leg openings LH are less likely to get caught on the legs of the wearer when worn, compared with the boxer-shaped wearable article 200 like the comparative example. In addition, the wearable article 1 has a stretch suppressing portion 20 as a member for suppressing stretching in the up-down direction. Therefore, as Figure 6 As shown in B, the leg openings LH are prevented from being caught on the legs of the wearer and causing the wearable article 1 to be stretched up and down, and the entire wearable article 1 can be pulled up smoothly.

[0154] After the wearable article 1 has been pulled up near the crotch area of ​​the wearer, the positions of the wearable article 1 and the absorbent pad 100 are adjusted, such as Figure 7 C. In the wearable article 1, the wearable article 1 and the absorbent pad 100 are firmly joined via the joining area 30 (absorbent pad joining area 120), and therefore, by pulling the wearable article 1 to adjust the position of the wearable article 1, the position of the absorbent pad 100 can be adjusted together with the position of the wearable article 1. Therefore, the absorbent pad 100 can be appropriately fitted to the crotch area of ​​the wearer.

[0155] <Transformation of Wearable Item 1>

[0156] When wearing wearable item 1, if Figure 7 As shown in FIG. 1A , the wearer must first pass both legs through the waist opening BH and the leg openings LH. At this time, the wearable article 1 is pulled to both sides in the left and right directions with both hands to expand the waist opening BH and the leg openings LH. In the case of a panty-type wearable article made of a highly stretchable knitted fabric, like the wearable article 1, it is usually easy to stretch the wearable article even with a weak force, so that the waist opening BH can be greatly expanded in the left and right directions.

[0157] However, when such a wearable article is stretched significantly in the left - right direction, there is a risk of more likely shrinking in the up - down direction. Figure 8 A and Figure 8 B are diagrams showing the deformation that occurs when an underwear - type wearable article made of knitted fabric is stretched in the left - right direction. Figure 8 A shows the wearable article 1 in a natural state. In Figure 8 the natural state of A, the length of the wearable article 1 in the left - right direction is L0, and the length of the wearable article in the up - down direction is H0.

[0158] Figure 8 B shows the state when the waist region BR of the wearable article 1 is stretched from the natural state to 200% of its length in the left - right direction. In other words, it shows the state when the wearable article 1 is stretched until its length in the left - right direction becomes 2L0. In Figure 8 B, the length of the wearable article 1 in the up - down direction is H1, which is shorter than H0 (H1 < H0). That is, when the wearable article 1 expands from the natural state until its left - right dimension becomes 200%, its up - down dimension decreases from H0 to H1. This is due to the nature of the knitted fabric that constitutes the wearable article 1.

[0159] As described above, a typical knitted fabric is formed into a flat shape by forming loops with yarn and connecting adjacent loops. When the connected loops are pulled in a certain direction (for example, the so - called "course direction"), each loop deforms in such a way that it is crushed in the direction crossing the certain direction (the so - called "wale direction"). This causes the knitted fabric to shrink in the direction crossing the direction in which it is pulled.

[0160] In the present embodiment, the wearable article 1 has a joining region 30 provided at a predetermined position in the up - down direction, and the absorbent pad 100 is attached by joining the absorbent - pad joining region 120 of the absorbent pad 100 to the joining region 30. Therefore, as Figure 8 A and Figure 8 B show, when the wearable article 1 shrinks in the up - down direction, the up - down position of the joining region 30 changes, and this causes a misalignment in the up - down position between the wearable article 1 and the absorbent - pad joining region 120 provided in the absorbent pad 100, resulting in a risk of making it difficult for the two to be joined to each other.

[0161] Therefore, in the wearable article 1, the leg opening LH is formed so that when the wearable article 1 is stretched in the left-right direction from the natural state, the distance from the upper end of the joining region 30 to the lower end of the wearable article 1 is less likely to decrease, and this makes it less likely that the position of the joining region 30 deviates in the up-down direction. Figure 8 In the embodiment of the wearable article 1, when the waist region BR is stretched by 200% in the left-right direction, the waist region BR is significantly contracted in the up-down direction. On the other hand, in the case of the crotch region CR located below the waist region BR and between the pair of leg openings LH, LH in the left-right direction, the left-right stretch is smaller than that of the waist region BR, so the up-down contraction is also smaller. In other words, by adjusting the size and shape of the leg openings LH, the up-down contraction amount of the crotch region CR of the wearable article 1 can be adjusted. The up-down contraction amount of the wearable article 1 will be described below.

[0162] Fig. 9 A and Fig. 9 B is a diagram illustrating the amount of contraction in the up-down direction when the wearable article 1 is stretched 200% in the left-right direction from the natural state. Fig. 9 A and Fig. 9 B is a schematic cross-sectional view of the wearable article 1 to which the absorbent pad 100 is attached, when viewed in the left-right direction. Fig. 9 A shows the wearable article 1 and the absorbent pad 100 in their natural state, and Fig. 9 B shows the waist region BR of the wearable article 1 when it is changed from the natural state ( Fig. 9 A) State when stretched 200% in the left-right direction. In addition, the wearable article 1 has the joining regions 30 (31, 32) on both the front and rear sides in the front-back direction, but it can be considered that any of the joining regions 30 (31, 32) located on the front and rear sides has a similar structure. Therefore, the following description will focus on the front joining region 31 located on the front side.

[0163] When attaching the absorbent pad 100 to the wearable article 1, the absorbent pad 100 is inserted from the upper side to the inner side of the waist opening BH of the wearable article 1 in a state where the absorbent pad 100 is folded in half at the folding line which is the center position CL in the longitudinal direction, and is arranged so that the folding line of the absorbent pad 100 contacts the lowermost portion (the lowermost portion) of the wearable article 1. Fig. 9 In this state, the vertical heights of the joining region 30 and the absorbent pad joining region 120 are adjusted so that the front joining region 31 of the wearable article 1 and the front absorbent pad joining region 121 of the absorbent pad 100 can be joined to each other. That is, in a state where the folding line (CL) of the absorbent pad 100 is located at the lower end 1b0 of the wearable article 1, there is a portion where the front joining region 31 and the front absorbent pad joining region 121 overlap in the vertical direction. In addition, Fig. 9 In the natural state of A, the vertical length from the upper end 31t of the front side joint area 31 to the lower end 1b0 of the wearable article 1 is length h0, and the vertical length of the front side joint area 31 (the distance between the upper end 31t and the lower end 31b) is length L31.

[0164] Next, when the waist region BR of the wearable article 1 is pulled to both sides in the left-right direction and extended to 200% in the left-right direction from the natural state, as shown in FIG. Fig. 9 As shown in B, the wearable article 1 shrinks in the up-down direction. Fig. 9 In the state B, if the vertical position (height) of the upper end 31t of the front side joint area 31 is Fig. 9 The upper end 31t of A is aligned at the same height in the vertical direction, and the lower end position of the wearable article 1 is Fig. 9 1b0 in A moves to Fig. 9 1b in B s At this time, in the contracted state, the area from the upper end 31t of the front joining region 31 to the lower end 1b of the wearable article 1 s The length in the vertical direction is h s In other words, by stretching the wearable article 1 to 200% in the left-right direction from the natural state, the vertical length h0 from the upper end 31t of the front joint region 31 to the lower end 1b0 of the wearable article 1 is reduced (h0-h s In other words, the vertical position of the lower end 1b0 of the wearable article 1 has moved upward (h0-h s ).

[0165] On the other hand, Fig. 9 In B, the absorbent pad 100 is not stretched in the left-right direction, and the absorbent pad 100 does not shrink in the up-down direction. Therefore, the position of the lower end 1b0 of the wearable article 1 moves upward (h0-h s ), the position of the absorbent pad 100 also moves upward as a whole (h0-h s That is, the position of the front absorbent pad joint area 121 of the absorbent pad 100 moves upward (h0-h s As a result, if there is no portion where the front absorbent pad joining region 121 and the front joining region 31 of the wearable article 1 overlap in the up-down direction, it becomes difficult to join the front absorbent pad joining region 121 and the front joining region 31 to each other.

[0166] On the contrary, even if the position of the front side absorbent pad joint area 121 is moved upward (h0-h s), if there is a portion thereof overlapping with the front side joining region 31 in the up-down direction, this makes it possible to join the front side absorbent pad joining region 121 and the front side joining region 31 to each other. Fig. 9 In FIG. 1B, in the vertical direction, the lower end 121b of the front absorbent pad joining region 121 is located below the upper end 31t of the front joining region 31 and above the lower end 31b, so that there is a portion where the front absorbent pad joining region 121 and the front joining region 31 overlap each other, so that they can be joined to each other. In other words, if the vertical length L31 of the front joining region 31 is greater than the upward movement amount (h0-h s ), the front side absorption pad bonding area 121 and the front side bonding area 31 can be bonded to each other (L31>h0-h s ).

[0167] In the wearable article 1 of the present embodiment, the pair of leg openings LH, LH are formed so that the length h s Not shorter than length h0 by twice or more than length L31 (h s >h0-L31×2): length h s is the vertical length from the upper end 31t of the front side joint area 31 to the lower end 1b0 of the wearable article 1 when the wearable article 1 has been stretched to 200% in the left-right direction from the natural state; the length h0 is the vertical length from the upper end 31t of the front side joint area 31 to the lower end 1b0 of the wearable article 1 in the natural state; and the length L31 is the vertical length of the front side joint area 31. In other words, the leg openings LH, LH are formed so that the vertical length L31 of the front side joint area 31 is greater than the upward movement amount (h0-h0) of the front side absorbent pad joint area 121. s ) half (L31>(h0-h s ) / 2).

[0168] As a result, even if the waist region BR is stretched in the left-right direction when the wearable article 1 is worn, contraction in the up-down direction is restricted in the crotch region CR between the leg openings LH, LH. This increases the possibility that there is a portion (engageable portion) where the joining region 30 provided in the wearable article 1 and the absorbent pad joining region 120 provided in the absorbent pad 100 overlap each other in the up-down direction. This can make it easier to join the absorbent pad 100 to the wearable article 1.

[0169] Furthermore, if the vertical length L31 of the front side joint region 31 is made larger than the upward movement amount (h0-h s )L31>h0-h s), the possibility that the joining region 30 and the absorbent pad joining region 120 overlap each other in the up-down direction can be increased. This can make it easier for the absorbent pad 100 to be joined to the wearable article 1.

[0170] Furthermore, in the wearable article 1 in the natural state, the upper end LHt of each leg opening LH is located at the lower end ( Fig. 9 1b0) on the upper side of A, and the wearable article 1 has a panty-like shape in which the leg opening LH is cut obliquely upward (see Figure 2 In this way, since the leg opening LH has a certain width in the up-down direction, it is similar to having Figure 5 Compared with the boxer shorts-shaped wearable article shown in the figure, the width of the waist region BR in the vertical direction is narrowed. In other words, the proportion of the waist region BR to the entire wearable article 1 in the vertical direction is reduced, and the proportion of the crotch region CR is increased. As described above, when the wearable article 1 is unfolded to the left and right, the vertical contraction is greater in the waist region, but the vertical contraction is smaller in the crotch region compared to the waist region. Therefore, the vertical contraction amount in the area from the upper end of the joining area 30 to the lower end of the wearable article 1 also becomes relatively small, making it less likely to cause vertical positional misalignment between the joining area 30 and the absorbent pad joining area 120 (see Fig. 9 B) This can make it easier to engage the absorbent pad 100 with the wearable article 1.

[0171] Furthermore, the joining region 30 of the wearable article 1 is provided in the waist region BR. Figure 2 As shown in FIG. 1A , in the up-down direction, the upper end 31t of the joining region 30 (31) is located below the central position CLBR of the waist region BR. In the present embodiment, by reducing the up-down distance change (contraction) between the upper end of the joining region 30 and the lower end of the wearable article 1, it is less likely to cause the up-down position misalignment of the joining region 30 and the absorbent pad joining region 120. Therefore, in the case where the upper end of the joining region 30 is located above the waist region BR, the up-down distance between the upper end of the joining region 30 and the lower end of the wearable article 1 increases, making the contraction ratio greater. This makes it more likely to cause the up-down position misalignment with the absorbent pad joining region 120. In comparison, since the upper end of the joining region 30 is located below the central position of the waist region BR, the distance from the upper end of the joining region 30 to the lower end of the wearable article 1 is shorter than in the opposite case. This reduces the up-down movement amount of the joining region 30 associated with the up-down contraction of the wearable article 1, making it easier for the absorbent pad 100 to be joined to the wearable article 1.

[0172] In addition, it is preferred that the stretchability of the joining region 30 is lower than the stretchability of the fabric constituting the wearable article 1 (main body 10). In other words, it is preferred that the force required to stretch the joining region 30 per unit length in the up-down direction and the left-right direction is greater than the force required to stretch the knitted fabric constituting the main body 10 per unit length in the up-down direction and the left-right direction. With this configuration, when the wearable article 1 is pulled in the left-right direction, the influence of the stretch in the area above the joining region 30 is less likely to extend to the area below the joining region 30 (including the crotch region CR). In other words, by the joining region 30 as a boundary, it is more likely to suppress the contraction in the up-down direction in the lower area (crotch region). In addition, since the joining region 30 itself is less likely to stretch in the up-down direction, it is more likely to suppress the contraction of the wearable article 1 as a whole in the up-down direction. This makes it less likely that the joining region 30 moves in the up-down direction and makes it easier for the absorbent pad 100 to be joined to the wearable article 1.

[0173] Furthermore, it is preferable that there is a portion where the joining region 30 and the crotch region CR overlap each other in the left-right direction. Since the wearable article is less likely to stretch in the left-right direction in the joining region 30 having lower elasticity than other regions, the left-right stretching of the crotch region CR is less likely to be suppressed in the portion overlapping with the joining region 30. Therefore, even if the wearable article 1 is extended in the left-right direction, the contraction of the crotch region CR in the up-down direction is suppressed, making it less likely that the joining region 30 moves in the up-down direction. This can make it easier for the absorbent pad 100 to be joined to the wearable article 1.

[0174] Furthermore, the crotch region CR of the wearable article 1 has a stretch-reduction restraining member (stretch-reduction restraining portion 20) having a predetermined length in both the up-down direction. Figure 2 , the central stretch suppressing parts 21 and 22 are provided as stretch suppressing parts that extend over the crotch region CR in the up-down direction. The central stretch suppressing parts 21, 22 are formed by a process such as sewing a thread having low stretchability into a specified part of the main body part 10 composed of a knitted fabric having high stretchability, and are less likely to shrink in the up-down direction than a part that is not subjected to such a process. Therefore, even when the wearable article 1 is stretched in the left-right direction, the part where the stretch suppressing parts (central stretch suppressing parts 21, 22) of the crotch region CR are located is less likely to shrink in the up-down direction. This reduces the amount of up-down movement of the joining area 30, making it easier for the absorbent pad 100 to join with the wearable article 1.

[0175] Furthermore, the expansion and contraction suppressing member (central expansion and contraction suppressing parts 21, 22) is continuously arranged from the crotch region CR to the waist region BR located above the upper end of the crotch region CR in the vertical direction. Therefore, in the portion where the central expansion and contraction suppressing parts 21 and 22 are arranged, it is highly possible to suppress the vertical contraction over a wide area in the vertical direction of the wearable article 1. This reduces the vertical movement amount of the joining region 30, making it easier to join the absorbent pad 100 to the wearable article 1.

[0176] In addition, the expansion and contraction suppression member (central expansion and contraction suppression parts 21, 22) is arranged in the central part in the left-right direction. When trying to unfold the wearable article 1 on both sides in the left-right direction, the central part in the left-right direction is most likely to shrink. That is, the wearable article 1 is likely to shrink the most in the vertical direction in the central part in the left-right direction. In contrast, by arranging the central expansion and contraction suppression parts 21 and 22 in the central part in the left-right direction, it is more likely to suppress excessive contraction of the wearable article 1 in the central part in the left-right direction. This reduces the vertical movement amount of the joining area 30, making it easier for the absorbent pad 100 to join with the wearable article 1.

[0177] In addition, a pair of side expansion and contraction suppression parts 23, 23 (24, 24) (side expansion and contraction suppression parts) having a predetermined length in the vertical direction are provided on both sides of the central expansion and contraction suppression part 21 (22) in the left and right directions (see Figure 2 ). Like the central stretch suppressing portion 21 (22), the side stretch suppressing portion 23 (24) also has the function of a stretch suppressing member that suppresses the stretching of the main body portion 10 in the vertical direction. Therefore, when the wearable article 1 is attempted to be unfolded on both sides in the left-right direction, the provision of the side stretch suppressing portion 23 (24) makes it possible to suppress the vertical contraction on both sides in the left-right direction. In other words, it becomes easier to suppress the vertical contraction over a wide range in the left-right direction of the wearable article 1, so that the vertical movement amount of the bonding area 30 can be reduced. This can make it more likely that the absorbent pad 100 is bonded to the wearable article 1.

[0178] Furthermore, in the wearable article 1 of the present embodiment, the expansion and contraction suppression part (expansion and contraction suppression part 20) does not include an elastic member. That is, when the expansion and contraction suppression part 20 is formed on the main body part 10, a process of welding or press-joining a member having elasticity such as silicone or rubber is not performed. In the case where the expansion and contraction suppression part 20 includes a member having elasticity, the elastic force exerted by the elastic member may cause the wearable article 1 to be more likely to shrink in the up-down direction, even in a natural state. In contrast, if the expansion and contraction suppression part (expansion and contraction suppression part 20) does not include an elastic member, the wearable article 1 will not shrink in the up-down direction at least in a natural state, so that it is possible to prevent the wearable article 1 from shrinking too much in the up-down direction when it is unfolded in the left-right direction. This can reduce the amount of up-down movement of the joining area 30.

[0179] In addition, a leg opening covering stitch 13 is formed along the periphery of each leg opening LH, LH. The leg opening covering stitch 13 increases the rigidity of the periphery of each leg opening LH, LH provided on both sides of the crotch region CR, thereby weakening the elasticity of both sides of the crotch region CR. Therefore, both sides of the crotch region CR are less likely to shrink in the up-down direction, and therefore, the up-down direction distance between the upper end of the joining region 30 and the lower end of the wearable article 1 is less likely to change. This makes it possible to reduce the up-down direction movement amount of the joining region 30. This can make it more likely that the absorbent pad 100 is joined to the wearable article 1.

[0180] In addition, a crotch seam 12 having a specified length in the left-right direction is provided in the lower end portion (crotch region CR) of the wearable article 1. The crotch seam 12 increases the rigidity of the lower end portion of the crotch region CR, making it easier to suppress expansion and contraction in the left-right direction. In other words, even when the waist region BR is expanded in the left-right direction, the crotch region CR is unlikely to be stretched in the left-right direction. Therefore, the contraction in the up-down direction of the crotch region CR is also suppressed, and the amount of up-down movement of the joining region 30 can be reduced. This can make it easier to combine the absorbent pad 100 with the wearable article 1.

[0181] In the wearable article 1, there is a portion where the crotch sewing portion 12 and the leg opening covering sewing portion 13 intersect each other. By connecting the two portions and acting like a frame, the rigidity of the lower end portion of the crotch region CR and both sides of the crotch region CR is increased, making it easier to suppress excessive expansion and contraction of the crotch region CR as a whole. In other words, it is very likely to suppress the left-right stretching of the crotch region CR and the up-down contraction of the crotch region CR. This reduces the up-down movement amount of the joining region 30, making it easier for the absorbent pad 100 to join with the wearable article 1.

[0182] Furthermore, in the wearable article 1, with regard to the maximum length from the upper end of the joining region 30 to the lower end of the wearable article 1, it is preferred that when the waist region BR is stretched 200% ( Fig. 9 h in A s ) to the maximum length in the natural state ( Fig. 9The force required to stretch the maximum length when the wearable article 1 is stretched by 200% in the left-right direction (h0 in A) is 1 / 5 or less of the force required to stretch the waist region BR by 200% from the natural state in the left-right direction. In other words, even if the length in the up-down direction from the upper end of the joining region 30 to the lower end of the wearable article 1 is reduced by 200% in the left-right direction, it is preferable that the length can be stretched by a weak force by the amount of contraction. With this configuration, when the wearable article 1 is expanded in the left-right direction and the absorbent pad 100 is inserted into the wearable article 1, even if the up-down direction dimension of the wearable article 1 has been reduced, the up-down direction dimension can be restored to their original state (the up-down direction dimension in the natural state) by gently pushing the absorbent pad 100 into the crotch side.

[0183] In other words, it is easier to restore the length from the upper end of the joining region 30 to the lower end of the wearable article 1 to the original state than in the opposite case (a case where the force required to stretch the maximum length when the waist region BR is stretched 200% from the natural state to the maximum length in the natural state in the left-right direction is greater than 1 / 5 of the force required to stretch the waist region BR from the natural state in the left-right direction by 200%). Therefore, it is less likely that the positional misalignment between the joining region 30 of the wearable article 1 and the absorbent pad joining region 120 in the up-down direction occurs, making it easier for the absorbent pad 100 to be joined to the wearable article 1.

[0184] <Container for wearable article 1>

[0185] The wearable article 1 manufactured in a factory or the like is compactly folded and then transported and circulated on the market in a state where one or more wearable articles are accommodated in a predetermined accommodation member. A wearable article accommodation body 90 in which a plurality of wearable articles 1 are accommodated in an accommodation member 70 will be described below.

[0186] Fig.10 1 is a schematic perspective view illustrating an example of a wearable article housing body 90 (hereinafter also simply referred to as "housing body 90"). The housing body 90 includes a housing member 70 as a bag-like member and one or more wearable articles 1 housed inside the housing member 70. Note that the absorbent pad 100 is not housed in the housing body 90; when a user uses the wearable article 1 and the absorbent pad 100 together, he / she needs to purchase or otherwise prepare the absorbent pad 100 separately.

[0187] like Fig.10 As shown, the receiving body 90 has a first direction, a second direction and a third direction intersecting each other. One side of the first direction is the upper side, and the other side is the lower side. Similarly, one side of the second direction is the right side, and the other side is the left side; and one side of the third direction is the front side, and the other side is the rear side.

[0188] like Fig.10 As shown, the storage member 70 is a substantially rectangular parallelepiped container, and is formed by folding a base sheet 71 as a sheet member constituting the storage member 70 and joining predetermined portions thereof. The base sheet 71 is a sheet member made of resin, and, for example, a liquid-impermeable resin such as polyethylene, polypropylene, polyvinyl chloride, polystyrene, polycarbonate, polyethylene terephthalate (PET), etc. can be used. When the wearable article 1 is stored in the storage member 70, first, the base sheet 71 is folded and formed into a bag shape (not shown) having an opening at an upper end portion in a first direction, and then a predetermined number of wearable articles 1 are stored through the upper end portion. After storing the wearable article 1, as shown in FIG. Figure 1 As shown, the base sheet 71 is folded at the upper end (e.g., folded with a gusset), and then the opposing surfaces are joined together to close the opening. Fig.10 As shown, a substantially rectangular parallelepiped-shaped receiving body 90 is formed. Note, however, that the shape of the receiving member 70, the method for folding the base sheet 71, and the method for enclosing the wearable article 1 are not limited to the above.

[0189] The front side surface of the storage member 70 in the third direction corresponds to the front side of the storage body 90 viewed by the user in a store, etc. Information including letters and pictures is indicated (printed) on the front surface of the storage member 70 . Fig.10 Examples of the product name indicator 72 include a product name indicator 72, a product image indicator 73, an explanation indicator 74, and a note indicator 75. The product name indicator 72 is a portion for indicating information showing the product name of the wearable article 1, and the user can use the product name indicator 72 as a guide for selecting and purchasing the wearable article 1 from a variety of types of absorbent articles. The product image indicator 73 is a portion for indicating information showing an image related to the wearable article 1 and / or the user. The user looks at the product image indicator 73, thereby being able to grasp the overview of the product and who the target wearer of the product is at a glance.

[0190] The description label portion 74 is a portion for labeling information showing a product description of the wearable article 1, and includes at least a label that reminds people that the wearable article is to be used in combination with the absorbent pad 100. Fig.10 In the description mark portion 74, there is a mark indicating information of the fact that the wearable article 1 can be used in combination with an absorbent pad and the type of the absorbent pad (absorbent pad 100) to be used in combination. The comment mark portion 75 is a portion for indicating comments other than the information indicated in the description mark portion 74, and shows information useful to the user. Fig.10 In the wearable article 1, there is a mark indicating information that the wearable article 1 can be reused, so that the user can recognize that the wearable article 1 can be reused.

[0191] Note that these information marking portions 72-75 do not need to be printed on the base sheet 71 constituting the housing member 70, but may be formed, for example, by attaching a sticker including a marking of predetermined information to the surface of the base sheet 71. In addition, in the case where the base sheet 71 is a transparent sheet member, a card or the like having a marking of predetermined information may be enclosed in such a manner that the card or the like is visible from the outside.

[0192] By distributing such a housing body 90 on the market, a user who observes the housing body 90 can easily recognize the function of the wearable article 1 and how to use the wearable article 1, so that the wearable article 1 can be used correctly.

[0193] <Washing of wearable article 1>

[0194] It has been described above that the wearable article 1 can be washed and reused, and in the case where the article is washed, it is important that the article is easy to dry. For example, assuming that the wearer of the wearable article 1 washes and dries the wearable article 1 while bathing, and wears the washed wearable article 1 again after bathing, it is preferred that the wearable article 1 has high dryability.

[0195] In the wearable article 1 of the present embodiment, dryability is improved by the following construction. First, the construction for improving dryability will be described from the perspective of the fabric constituting the wearable article 1. In the present embodiment, the fabric constituting the wearable article 1 (main body 10) contains at least 90% by weight of polyester or polyethylene. Polyester and polyethylene are materials having high elongation compared to cotton, and therefore, containing a large amount of such materials can further promote elongation. In addition, polyester and polyethylene are materials having non-water absorbency and quick dryability, and therefore, the time required for drying after washing can be reduced, thereby improving the dryability of the wearable article 1. Note that the composition of the fabric (the weight percentage of each material) can be verified by measurement, or can be verified by checking the "mixing ratio" written on the product label.

[0196] In addition, in the present embodiment, the fabric constituting the wearable article 1 does not contain any water-absorbent material. Examples of water-absorbent materials include cotton, rayon, etc. By not containing any water-absorbent material, the fabric is less likely to absorb water, and therefore, the time required for drying after washing can be reduced, thereby improving the dryability of the wearable article 1.

[0197] In addition, the fabric constituting the wearable article 1 contains less than 10% by weight of a material having a higher elasticity than polyester or polyethylene. Examples of materials having higher elasticity may include polyurethane, etc. Since the fabric constituting the wearable article 1 contains 90% by weight or more of polyester or polyethylene, by including the above-mentioned material having a higher elasticity accounting for less than 10% by weight in the remaining part, the elasticity can be improved while ensuring good dryability. Note that if the mixing ratio of the highly elastic material is too high (10% by weight or more), the fabric may shrink to the extent that wrinkles are generated in the wearable article 1 (main body 10), or the fabric may shrink excessively and make it likely that the legs are easily stuck when passing the legs through the leg openings LH, LH. Therefore, it is preferred that the mixing ratio is less than 10% by weight.

[0198] In addition, the fabric constituting the wearable article 1 includes a region containing a material having a higher stretchability than polyester or polyethylene and a region not containing the material. For example, by arranging a highly stretchable material in a region of the wearable article 1 where fit is particularly required (i.e., by forming a region containing a material having a higher stretchability), fit can be further improved in a limited region of the wearable article 1, thereby improving functionality. Alternatively, in addition to improving fit in a specific region by, for example, providing a region containing a material having a higher stretchability in a plurality of regions with spaces therebetween, fit can be improved over the entirety of the wearable article 1.

[0199] Next, the configuration for improving dryability will be described from the perspective of the joining region 30. As described above, it is preferred that the joining region 30 be provided with a separate sheet member (e.g., hook and loop fastener) different from the knitted fabric constituting the main body portion 10, and it is also preferred that the separate sheet member be composed of polyethylene or polyester. Since the separate sheet member is joined to the main body portion 10, the dryability of the wearable article 1 is improved by making the separate sheet member of a material having quick dryability like the main body portion 10.

[0200] In addition, the separate sheet member is joined to the fabric (main body 10) constituting the wearable article 1 by sewing with thread along the peripheral edge of the separate sheet member. Therefore, in the area inside the peripheral edge that has been sewn with thread, the fabric and the separate sheet member are not tightly adhered (not joined) in the thickness direction, and a space is formed between the separate sheet member and the fabric. That is, the entire separate sheet member is not in a state of being joined to the fabric, and therefore, compared with the case where the entire sheet member is joined to the fabric, the surface of the separate sheet member that contacts the fabric has a wide area in contact with the air, which makes it easy for moisture to evaporate. This structure that allows air to escape easily improves dryability.

[0201] In addition, in the present embodiment, when viewed in the thickness direction, there is a portion where the separate sheet member and the expansion and contraction suppressing portion 20 (the front central expansion and contraction suppressing portion 21; the rear central expansion and contraction suppressing portion 22) overlap each other (see FIG. Figure 2 ). More specifically, the separate sheet member is arranged to straddle the region (stretch suppressing portion 20) having different shrinkage forces. By providing the stretch suppressing portion 20, a change in shrinkage force occurs in the fabric constituting the wearable article 1, and a space is more likely to be formed between the skin side of the fabric and the non-skin side of the separate sheet member. By allowing air to easily escape from such a space, dryability is improved.

[0202] In addition, regarding the size of the individual sheet member, it is preferred that the length in the up-down direction is 50 mm or less and the length in the left-right direction is 150 mm or less. If the individual sheet member is too large, the sheet member portion may become difficult to dry. By adjusting the size within the above range, it becomes easier to dry while ensuring an area that can maintain sufficient bonding force with the fabric.

[0203] In addition, it is preferred that the thickness of the individual sheet member is 3 mm or less. In this way, since the sheet member is not too thick, easy dryability can be maintained while ensuring a thickness capable of maintaining sufficient bonding force with the fabric.

[0204] Next, the structure for improving the dryability will be described from another viewpoint. Fig.11 This is a schematic plan view showing a state in which the left and right ends of the front waist region BR and the back waist region BR of the wearable article 1 have been cut off and the wearable article has been unfolded in the vertical direction. More specifically, the aforementioned "expanded state" refers to a state in which the wearable article that has been unfolded in the vertical direction is kept still on a horizontal surface in a natural state. Fig.11 In the expanded state, area S1 ( Fig.11The area of ​​the region S1 (shown by hatching in the figure) is smaller than the area of ​​the remaining region S2, and the region S1 is an area between the upper end 31ue of the front side joint region 31 and the upper end 32ue of the rear side joint region 32 in the up-down direction and between the respective ends 31pe, 32pe of the front side joint region 31 and the rear side joint region 32 most toward one side (left side) and the respective ends 31re, 32re of the front side joint region 31 and the rear side joint region 32 most toward the other side (right side) in the left-right direction. The region S1 within the fabric constituting the wearable article 1 is generally an area covered by the absorbent pad 100 when the absorbent pad 100 is attached. Therefore, if drying is somewhat insufficient after washing the wearable article 1, or if the wearable article 1 becomes wet after the absorbent pad 100 is attached for some other reason, the region S1 is likely to have low dryability thereafter because it is covered by the absorbent pad 100. However, by making the area of ​​the region S1 smaller than the area of ​​the region S2 in the fabric constituting the wearable article 1, it is easier to suppress the deterioration of the dryability of the entire wearable article 1, compared with the opposite case.

[0205] Note that in the present embodiment, the area of ​​the region S1 is smaller than the area of ​​the remaining region S2, but this is not a limitation. Contrary to the above, the area of ​​the region S1 may be larger than the area of ​​the remaining region S2. In this case, even if drying is somewhat insufficient after washing the wearable article 1, the region S1 will be covered by the absorbent pad 100, and therefore, the skin is less likely to get wet and the wearing comfort is less likely to be impaired.

[0206] ===Others===

[0207] The foregoing embodiments are merely for facilitating the understanding of the present invention and should not be construed as limiting the present invention. It goes without saying that the present invention can be changed or improved without departing from the gist of the present invention and encompasses its equivalents.

[0208] The foregoing embodiment explains an example in which the expansion and contraction suppressing portion 20 is provided as a expansion and contraction suppressing member configured to suppress expansion and contraction of the main body portion 10, but an expansion and contraction suppressing member other than the expansion and contraction suppressing portion 20 may be provided. For example, providing a separate sheet member (e.g., a hook and loop fastener) in the joining region 30 helps suppress expansion and contraction of the main body portion 10 in the joining region 30. That is, the joining region 30 may also function as the expansion and contraction suppressing member.
