  • the wearable article container of aspect 1 even if the waist area is expanded in the left-right direction when wearing the wearable article contained in the container, vertical contraction is restricted in the area between the pair of leg openings, and the length from the upper end of the engagement area to the lower end of the wearable article is unlikely to contract. Therefore, when the absorbent pad is inserted up to the crotch part of the wearable article, there is a high probability that the engagement area on the wearable article and the absorbent pad engagement area on the absorbent pad will have overlapping portions (engageable portions) in the vertical direction. Therefore, it is possible to provide a wearable article and a container thereof that are easy to engage with the absorbent pad.

Therefore, when the absorbent pad is inserted up to the crotch part of the wearing article, there is a high probability that the engagement region on the wearing article and the absorbent pad engagement region on the absorbent pad will have overlapping portions (engageable portions) in the vertical direction. This makes it easier to engage the absorbent pad with the wearing article.
  • the wearing article of aspect 3 can increase the probability that the engagement area of the wearing article and the engagement area of the absorbent pad will have overlapping portions in the vertical direction. This makes it easier to engage the absorbent pad with the wearing article.
  • the leg openings are formed at an angle, so that the proportion of the waist area formed above the upper end of the leg openings in the vertical direction in the wearing article is reduced.
  • the width of the waist area, which is likely to shrink in the vertical direction, is narrowed, so that the amount of vertical shrinkage of the wearing article as a whole is smaller than that of boxer shorts-type wearing articles, etc. Therefore, the engagement area of the wearing article and the absorbent pad engagement area tend to overlap in the vertical direction, making it easier to engage the absorbent pad with the wearing article.
  • Aspect 5 The wearing article according to any one of Aspects 2 to 4, further comprising a waist region located between upper ends of the leg openings and an upper end of the wearing article in the vertical direction, the engagement region being provided within the waist region, and an upper end position of the engagement region being lower than a center position of the waist region in the vertical direction.
  • the upper end of the engagement region is located lower than the center position of the waist region, so the distance from the upper end of the engagement region to the lower end of the wearing article is shorter than in the opposite case. This reduces the vertical positional shift of the engagement region that occurs when the wearing article contracts in the vertical direction, making it easier to engage the absorbent pad with the wearing article.
  • the effect of stretching in the area above the engagement area is less likely to extend to the area below the engagement area, making it easier to suppress vertical contraction in the lower area.
  • the engagement area itself is less likely to expand and contract vertically, vertical contraction of the wearable article as a whole is more likely to be suppressed. This makes it harder for the engagement area to shift position vertically, making it easier to engage the absorbent pad with the wearable article.
  • the wearing article of aspect 7 tends to suppress left-right expansion of the crotch region in the area that overlaps with the engagement region. This suppresses up-down contraction of the crotch region, making it difficult for the engagement region to shift position in the up-down direction. This makes it easier to engage the absorbent pad with the wearing article.
  • a wearing article according to any one of Aspects 2 to 7, wherein the crotch region is provided with stretch suppressing means having a predetermined length in the vertical direction.
  • the portion of the crotch region where the stretch suppression means is provided is less likely to shrink in the up-down direction. This reduces the vertical positional deviation of the engagement region, making it easier to engage the absorbent pad with the wearable article.

  • the wearing article of aspect 9 makes it easier to suppress vertical contraction over a wide range in the vertical direction (from the crotch region to the waist region). This reduces the vertical positional deviation of the engagement region, making it easier to engage the absorbent pad with the wearing article.

  • the rigidity of the periphery of the leg openings is increased by the overlocking, which weakens the stretchability of both sides of the crotch region. This makes it difficult for both sides of the crotch region to contract in the vertical direction, and reduces the vertical positional deviation of the engagement area. This makes it easier to engage the absorbent pad with the wearing article.
  • a wearing article according to any one of Aspects 2 to 12, wherein a crotch seam having a predetermined length in the left-right direction is provided at a lower end in the up-down direction.
  • the crotch seam increases the rigidity of the lower end of the crotch region, suppressing stretching in the left-right direction. Therefore, even if the worn article is spread out on both sides in the left-right direction, the crotch region is less likely to stretch in the left-right direction, and vertical contraction of the crotch region is also more likely to be suppressed. This reduces the vertical positional deviation of the engagement region, making it easier to engage the absorbent pad with the worn article.
  • the crotch seam and the leg overlock seam are connected to function like a skeleton, which increases the rigidity of the lower end and both sides of the crotch area, making it easier to suppress excessive stretching of the crotch area as a whole. This reduces the vertical positional deviation of the engagement area, making it easier to engage the absorbent pad with the wearing article.

  • the wearable article of aspect 15 at least in its natural state, the wearable article does not shrink in the vertical direction, so that it is easy to prevent the amount of vertical shrinkage from becoming excessively large when the wearable article is spread out in the left-right direction. This reduces the vertical positional deviation of the engagement area, making it easier to engage the absorbent pad with the wearable article.
  • a wearing article according to any one of aspects 2 to 15, wherein in a state in which an area above upper ends of the pair of leg openings is expanded 200% in the left-right direction from the natural state, a force required to extend a maximum length from an upper end of the engagement area to a lower end of the wearing article to a maximum length from the upper end of the engagement area to the lower end of the wearing article in the natural state is 1 ⁇ 5 or less of a force required to expand an area above upper ends of the pair of leg openings 200% in the left-right direction from the natural state.
  • the wearing article of aspect 16 even if the vertical dimension of the wearing article shrinks when the wearing article is opened in the left-right direction to insert the absorbent pad, the vertical dimension of the wearing article can be easily restored to its original dimension by gently pushing the absorbent pad toward the crotch side. Therefore, compared to the reverse case, the length from the upper end of the engagement area to the lower end of the wearing article can be easily restored to its original state. Therefore, vertical positional deviation between the engagement area of the wearing article and the engagement area of the absorbent pad is less likely to occur, making it easier to engage the absorbent pad with the wearing article.
  • polyester and polyethylene are materials that have higher elongation than cotton, and by including a large amount of such materials, it is possible to realize greater stretchability.
  • polyester and polyethylene are non-absorbent and highly quick-drying materials, which improves the drying properties of the wearable article.
  • the fabric does not absorb water easily because it does not contain a water-absorbent material. This shortens the drying time after washing and improves the drying properties of the wearable article.
  • the fabric constituting the wearable article is polyester or polyethylene, so that the remaining 10% by weight or less is made up of a material with higher elasticity, thereby ensuring good drying properties while improving elasticity.

  • the fabric and the separate sheet member are not in close contact (joined) in the thickness direction in the area inside the circumferential edge sewn with thread, and a space is formed between the separate sheet member and the fabric.
  • the surface area of the separate sheet member that comes into contact with the fabric is larger than when the entire sheet member is joined, making it easier for moisture to evaporate. This improves drying properties.
  • the provision of the stretch suppressing portion causes a change in the contraction force of the fabric constituting the wearing article, making it easier for a space to form between the skin side of the fabric and the non-skin side of the separate sheet member. Air can easily escape from such a space, improving the drying property.
  • the separate sheet member becomes too large, there is a risk that the portion of the sheet member in question will be difficult to dry, but by making the size within the above-mentioned range, the area is secured to maintain a sufficient engagement force with the fabric and the portion will be easier to dry.

  • region S1 of the fabric constituting the wearing article is the region that is covered by the absorbent pad when the absorbent pad is worn. Therefore, if the wearing article is not dried sufficiently after washing, or if the wearing article becomes wet after the absorbent pad is worn due to another factor, region S1 is likely to become less dry thereafter because it is covered by the absorbent pad. However, since the area of region S1 is smaller than the area of region S2 in the fabric constituting the wearing article, it is easier to suppress a decrease in the overall dryness of the wearing article compared to the reverse case.
  • a wearing article according to any one of aspects 2 to 25, wherein, in a state in which the front and rear waist regions of the wearing article are cut at both left-right ends and laid out in the up-down direction, an area of a region S1 between an upper end of the front engagement region and an upper end of the rear engagement region in the up-down direction and between one end of the front engagement region and the rear engagement region and the other end of the front engagement region and the rear engagement region in the left-right direction is larger than an area of the other region S2.

  • the side stretch suppressing part 23 (24) also functions as a stretch suppressing means for suppressing vertical stretch of the main body part 10, similar to the central stretch suppressing part 21 (22). Therefore, when the wearing article 1 is to be spread on both sides in the horizontal direction, the provision of the side stretch suppressing part 23 (24) makes it easier to suppress vertical contraction on both sides in the horizontal direction. In other words, vertical contraction is easily suppressed over a wide range in the horizontal direction of the wearing article 1, and the amount of movement of the engagement area 30 in the vertical direction can be reduced. This makes it easier to engage the absorbent pad 100 with the wearing article 1.
  • the stretch suppressing means does not include an elastic member. That is, when forming the stretch suppressing section 20 on the main body section 10, no processing is performed to weld or press an elastic member such as silicone or rubber. If an elastic member were included in the stretch suppressing section 20, the elastic force of the elastic member may cause the worn article 1 to easily shrink in the vertical direction even in the natural state. In contrast, if the stretch suppressing means (stretch suppressing section 20) does not include an elastic member, the worn article 1 does not shrink in the vertical direction at least in the natural state, and excessive vertical shrinkage when the worn article 1 is spread in the left and right direction can be suppressed. Therefore, the amount of movement of the engagement region 30 in the vertical direction can be reduced.
  • leg openings LH, LH are provided with leg overlock sections 13 along their periphery.
  • the leg overlock sections 13 increase the rigidity of the periphery of the leg openings LH, LH provided on both sides of the crotch region CR, thereby weakening the stretchability of both sides of the crotch region CR.
  • both sides of the crotch region CR are less likely to contract in the vertical direction, and the vertical distance between the upper end of the engagement region 30 and the lower end of the worn article 1 is less likely to change, making it possible to reduce the amount of vertical movement of the engagement region 30. This makes it easier to engage the absorbent pad 100 with the worn article 1.
  • a crotch seam 12 having a predetermined length in the left-right direction is provided at the lower end of the worn article 1 (crotch region CR).
  • the crotch seam 12 increases the rigidity of the lower end of the crotch region CR, making it easier to suppress expansion and contraction in the left-right direction.
  • the waist region BR is expanded in the left-right direction
  • the crotch region CR is less likely to stretch in the left-right direction. Therefore, contraction in the up-down direction of the crotch region CR is also suppressed, and the amount of movement of the engagement region 30 in the up-down direction can be reduced. This makes it easier to engage the absorbent pad 100 with the worn article 1.
  • the worn article 1 has an intersection between the crotch seam 12 and the leg overlock seam 13.
  • the two are connected and function like a skeleton, which increases the rigidity of the lower end and both sides of the crotch region CR, making it easier to suppress excessive stretching of the crotch region CR as a whole.
  • the left-right expansion and up-down contraction of the crotch region CR are more easily suppressed. This reduces the amount of movement of the engagement region 30 in the up-down direction, making it easier to engage the absorbent pad 100 with the worn article 1.
  • the force required to extend the maximum length (h s in FIG. 9A ) from the upper end of the engagement region 30 to the lower end of the wearing article 1 when the waist region BR is expanded 200% in the left-right direction from the natural state to the maximum length (h 0 in FIG. 9A ) from the upper end of the engagement region 30 to the lower end of the wearing article 1 in the natural state is preferably 1/5 or less of the force required to expand the waist region BR 200% in the left-right direction from the natural state.
  • the contracted length can be extended by a weak force.
  • the length from the upper end of the engagement region 30 to the lower end of the worn article 1 can be more easily returned to its original state. Therefore, vertical positional misalignment between the engagement region 30 of the worn article 1 and the absorbent pad engagement region 120 is less likely to occur, making it easier to engage the absorbent pad 100 with the worn article 1.

  • the base sheet 71 is a transparent sheet member, they may be constructed by enclosing a card or the like showing predetermined information inside so that the card can be seen from the outside.
  • the wearing article 1 can be washed and reused, and after washing, it is important that the wearing article 1 dries easily. For example, assuming a usage pattern in which the wearing article 1 is washed and dried while the wearer of the wearing article 1 is taking a bath, and the washed wearing article 1 is worn again after the wearer gets out of the bath, it is preferable that the wearing article 1 has high drying properties.
  • the wearable article 1 of this embodiment has the following configuration to improve the dryability.
  • the fabric that makes up the wearable article 1 main body 10) contains 90% or more by weight of polyester or polyethylene.
  • Polyester and polyethylene are materials with higher elongation than cotton, and by including a large amount of such materials, it is possible to realize greater stretchability.
  • polyester and polyethylene are non-absorbent and have high quick-drying properties, it is possible to shorten the drying time after washing, and the dryability of the wearable article 1 is improved.
  • the composition of the fabric (weight % of each material) can be confirmed by measurement, or the "mixing ratio" written on the product tag may be confirmed.
  • the fabric constituting the worn article 1 does not contain any absorbent material.
  • absorbent materials include cotton and rayon.
  • the fabric constituting the worn article 1 contains less than 10% by weight of a material that is more elastic than polyester or polyethylene.
  • a material that is more elastic than polyester or polyethylene examples include polyurethane. Since 90% by weight or more of the fabric constituting the worn article 1 is polyester or polyethylene, the remaining 10% by weight of the more elastic material described above can be included, thereby improving elasticity while ensuring good drying properties. If the mixing rate of such highly elastic materials is too high (10% by weight or more), there is a risk that the worn article 1 (main body 10) will shrink to the point of wrinkling, or that it will shrink so much that the legs will easily get caught when passing through the leg openings LH, LH, so it is preferable that the mixing rate is less than 10% by weight.
  • the fabric constituting the worn article 1 has regions that contain a material that is more elastic than polyester or polyethylene, and regions that do not. For example, by arranging a highly elastic material in a portion of the worn article 1 where a fit is particularly required (i.e., forming a region that contains a more elastic material), the fit can be improved in a limited portion of the worn article 1, improving functionality. In addition to improving the fit in a portion, the fit of the worn article 1 as a whole can also be improved by, for example, providing multiple areas spaced apart that contain a more elastic material.
  • the engagement region 30 is provided with a separate sheet member (e.g., a hook-and-loop fastener) that is different from the knitted fabric that constitutes the main body portion 10, and the separate sheet member is preferably made of polyethylene or polyester. Since the separate sheet member is joined to the main body portion 10, like the main body portion 10, the separate sheet member is also made of a material that has high quick-drying properties, thereby improving the drying properties of the worn article 1.
  • a separate sheet member e.g., a hook-and-loop fastener
  • the separate sheet member is joined to the fabric (main body 10) constituting the worn article 1 by sewing the peripheral portion of the separate sheet member with thread. Therefore, in the area inside the peripheral portion sewn with thread, the fabric and the separate sheet member are not in close contact (joined) in the thickness direction, and a space is formed between the separate sheet member and the fabric. In other words, since the entire separate sheet member is not joined to the fabric, the surface area of the separate sheet member that comes into contact with the fabric is larger than when the entire sheet member is joined, making it easier for moisture to evaporate. Such a configuration that allows air to easily escape improves drying properties.
  • the separate sheet member when viewed in the thickness direction, there is an overlapping portion between the separate sheet member and the stretch suppressing portion 20 (front central stretch suppressing portion 21 and rear central stretch suppressing portion 22) (see FIG. 2).
  • the separate sheet member is arranged to straddle areas of different contractile forces (stretch suppressing portions 20).
  • the provision of the stretch suppressing portion 20 causes a change in the contractile force of the fabric constituting the worn article 1, making it easier for a space to form between the skin side of the fabric and the non-skin side of the separate sheet member. Air can easily escape from such a space, improving dryness.
  • the size of the separate sheet member is 50 mm or less in the vertical direction and 150 mm or less in the horizontal direction. If the separate sheet member is too large, there is a risk that the part of the sheet member in question will be difficult to dry, but by making the size within the above-mentioned range, it will be easier to dry while ensuring an area that can maintain a sufficient engagement force with the fabric.
  • the thickness of the separate sheet member is 3 mm or less. This ensures that the thickness is sufficient to maintain a sufficient engagement force with the fabric, but is not too thick, so that it can be dried easily.

  • the area of the above-mentioned region S1 is smaller than the area of the remaining region S2, but this is not limited to this. Conversely, the area of region S1 may be larger than the area of the remaining region S2. In this case, even if the worn article 1 is slightly insufficiently dried after washing, the region S1 is covered by the absorbent pad 100, so that the skin is less likely to get wet and the wearing comfort is less likely to deteriorate.
