Description

Clothing capable of supporting an absorption pad or a diaper

[0001] The present invention relates to clothing capable of supporting an absorption pad or a diaper.

[0002] Patent Document 1 discloses a nursing pant comprising a pant body that divides the left and right side lines of the body and is capable of detachably locking the front and rear cut edges via a fastener, and a diaper support band provided on the inner surface of the pant body. According to such a nursing pant, the front body can be unfolded from the cut line of the left and right side lines, and the diaper can be put on and taken off in a lying position, facilitating the nursing work.

[0003] Japanese Patent Application Laid-Open No. 2000-45101

[0004] In the diaper support band (supporter part) of Patent Document 1, the front edge is sewn to the waistband of the front body, and the rear edge is sewn to the waistband of the rear body, respectively. At the part of the fastener (surface fastener) on the side parts of the front and rear bodies, the waistband of the front body and the waistband of the rear body are pulled against each other and are likely to be fixed by the wearer's lumbar vertebra, reducing the movement in the width direction (waist circumference direction). However, the width of the diaper support body of Patent Document 1 is narrow, and the diaper support body is sewn to a part of the waistband that is far from the fastener toward the inner side in the width direction and is relatively easy to move. Therefore, when the wearer's legs sandwich the crotch part of the diaper support body, the upper end part of the diaper support body is also likely to enter the inner side in the width direction. Then, the width of the absorption pad supported by the diaper support body becomes narrow, or the absorption pad is likely to come off from the diaper support body, making it easy for excrement to leak. Also, the area of the diaper supported by the diaper support body becomes small, reducing the adhesion of the diaper to the wearer and making it easy for excrement to leak.

[0005] The present invention has been made in view of the above problems, and its object is to suppress leakage of excrement in clothing capable of supporting an absorption pad or a diaper and having at least one side part on the left and right directions deployable.

[0006] The main invention for achieving the above objective is a garment capable of supporting an absorbent pad or diaper, comprising: a lower body portion that is worn on the lower body and has a front and back body, having mutually orthogonal vertical, left and right, and front and back directions, and being in the shape of trousers or a skirt, and comprising a front body portion and a back body portion; and a support portion provided on the skin side in the thickness direction of the lower body portion and having a support surface for supporting an absorbent pad or diaper, wherein the upper ends of the front and back support portions are fixed to the lower body portion by upper end fixing portions, respectively, the lower body portion and the support portion are expandable in the front and back directions at least on one side in the left and right directions, the lower body portion has an engaging portion that engages with the front body portion and the back body portion so as to overlap and to be removable on one side in the left and right directions, the engaging portion has a first engaging portion located above the upper end fixing portion, and in the expanded state of the lower body portion and the support portion in the vertical direction, The garment is capable of supporting an absorbent pad or diaper, characterized in that the upper end fixing portion on at least one side in the front-rear direction extends outward in the left-right direction beyond the inner end of the first engaging portion on one side in the left-right direction. Other features of the present invention will be made clear by description in this specification and the accompanying drawings.

[0007] According to the present invention, in clothing that can support an absorbent pad or diaper and has at least one side in the left-right direction that can be opened, leakage of excrement can be suppressed.

[0009] The following will become clear from the description in this specification and the accompanying drawings: (Aspect 1) An absorbent pad or diaper-supporting garment having mutually orthogonal vertical, left-right, and front-back directions, being in the shape of trousers or a skirt, comprising a front body and a back body, and comprising a lower body portion worn on the lower body, and a support portion provided on the skin side in the thickness direction of the lower body portion, and having a support surface for supporting an absorbent pad or diaper, wherein the upper ends of the front and back support portions are fixed to the lower body portion by upper end fixing portions, and at least on one side in the left-right direction, the lower body portion and the support portion Clothing capable of supporting an absorbent pad or diaper, characterized in that it is expandable in the front-to-back direction, the lower main body portion has an engagement portion on one side in the left-to-right direction that allows the front body portion and the back body portion to overlap and to be removably engaged, the engagement portion has a first engagement portion located above the upper end fixing portion, and in the expanded state of the lower main body portion and the support portion in the up-to-down direction, the upper end fixing portion on at least one side in the front-to-back direction extends outward in the left-to-right direction beyond the inner end of the first engagement portion on one side in the left-to-right direction.

[0010] According to Embodiment 1, one side of the support portion in the left-right direction is positioned near or overlapping with the engagement point of the first engagement portion, so that the support portion is worn in a state that is spread out in the left-right direction. Also, at the engagement point of the first engagement portion, the front and back panels pull against each other and are easily fixed at the wearer's hip bones. Therefore, one side of the support portion in the left-right direction is less likely to shift position, and the state in which the support portion is spread out in the left-right direction is easily maintained. As a result, unintended deformation of the absorbent pad and detachment from the support portion can be suppressed. In addition, an area where the diaper is supported by the support portion is secured, and it can be closely fitted to the wearer. Thus, leakage of excrement can be suppressed.

[0011] (Aspect 2) Clothing capable of supporting an absorbent pad or diaper as described in Aspect 1, wherein the first engaging portion has a rear first engaging portion provided on the back of the garment, and in the unfolded state, the rear upper end fixing portion extends outward in the left-right direction beyond the inner end of the rear first engaging portion on one side in the left-right direction.

[0012] According to embodiment 2, one side of the rear support portion in the left-right direction easily overlaps with the engagement point of the first engagement portion, so that the rear support portion is worn in a state that is spread out in the left-right direction. In addition, it is possible to prevent one side of the rear support portion in the left-right direction from shifting inward due to the curvature of the buttocks. Therefore, unintended deformation of the absorbent pad and detachment from the support portion can be suppressed. Furthermore, an area in which the diaper is supported by the support portion is secured, and it can be closely fitted to the wearer. Thus, leakage of excrement can be suppressed.

[0013] (Aspect 3) Clothing capable of supporting an absorbent pad or diaper as described in Aspect 2, wherein the lower main body and the supporter portion are expandable in the front-to-back direction on the other side in the left-to-right direction, the lower main body has an engagement portion on the other side that is removable and overlaps the front body and the back body on the other side in the left-to-right direction, the engagement portion on the other side is located above the upper end fixing portion and has a rear first engagement portion on the other side provided on the back body, and in the expanded state, the upper end fixing portion on the rear extends outward in the left-to-right direction beyond the inner end of the rear first engagement portion on the other side in the left-to-right direction.

[0014] According to embodiment 3, the rear support portion is attached in a state where it spreads outwards on both sides in the left-right direction. Furthermore, it is possible to prevent the left-right sides of the rear support portion from shifting inwards due to the curvature of the buttocks. Therefore, unintended deformation of the absorbent pad and detachment from the support portion can be prevented. In addition, an area where the diaper is supported by the support portion is secured, and it can be fitted snugly to the wearer. Thus, leakage of excrement can be prevented.

[0015] (Aspect 4) Clothing capable of supporting an absorbent pad or diaper as described in any of aspects 1 to 3, wherein the support portion has an elastic region on the left-right side portion that has greater elasticity in the vertical direction compared to the central portion.

[0016] According to embodiment 4, the support portion easily adheres to the wearer's legs, preventing displacement of the absorbent pad or diaper, and thus preventing leakage of excrement. Furthermore, the left and right sides of the upper end of the support portion, near the engagement point of the first engagement portion, are made easier to lift while spreading the crotch area of ​​the support portion outwards in the left and right directions via the stretchable area. As a result, the absorbent area of ​​the absorbent pad in the crotch area can be secured. Also, the area of ​​the diaper supported by the support portion in the crotch area is secured. Therefore, leakage of excrement can be prevented. In addition, it becomes easier to set the absorbent pad in the central part, which has less elasticity.

[0017] (Aspect 5) Clothing capable of supporting the absorbent pad or diaper described in Aspect 4, wherein the stretchable area has a highly contractile area that can be contracted in the vertical direction, and a low-contractile area located inside the highly contractile area in the left-right direction, wherein the contractile force in the vertical direction is smaller than that of the highly contractile area.

[0018] According to embodiment 5, the highly contractile area adheres closely to the wearer's legs, preventing the absorbent pad or diaper from shifting position and suppressing leakage of excrement. The low-contractile area suppresses the contraction of the absorbent pad or diaper while allowing it to adhere closely to the wearer's body, thereby suppressing leakage of excrement.

[0019] (Aspect 6) Clothing capable of supporting an absorbent pad or diaper as described in Aspect 5, wherein in the unfolded state, the maximum length in the left-right direction of the low-shrinkage region provided in at least one end region in the longitudinal direction of the three regions obtained by dividing the support portion into three equal parts in the longitudinal direction is longer than the maximum length in the left-right direction of the low-shrinkage region provided in the central region.

[0020] According to embodiment 6, the long, low-contraction region in the left-right direction allows the sides of the absorbent pad to stand up in the left-right direction, or the diaper to conform to the wearer's body, so as to wrap around the curves of the wearer's buttocks and abdomen, thereby ensuring a close fit between the absorbent pad or the diaper. This helps to suppress leakage of excrement.

[0021] (Aspect 7) Clothing capable of supporting an absorbent pad or diaper as described in any of aspects 1 to 6, wherein at least a part of the waist portion of the lower main body is expandable in the left-right direction, and the elasticity of the engagement region where the first engagement portion is provided in the waist portion of at least one of the front body and the back body is less than the elasticity of the region inside the engagement region in the left-right direction.

[0022] According to embodiment 7, when the first engaging portion is engaged, the area inside the first engaging portion extends, and the support portion is attached in a state where it spreads out in the left-right direction. As a result, the absorbent pad also fits snugly against the wearer in a wide state. In addition, an area is secured where the diaper is supported by the support portion, allowing it to fit snugly against the wearer. As a result, leakage of excrement can be suppressed.

[0023] (Aspect 8) Clothing capable of supporting an absorbent pad or diaper as described in any of aspects 1 to 7, wherein, in the unfolded state, the length in the left-right direction of the support portion at the rear upper end fixing portion is longer than the length in the left-right direction of the support portion at the front upper end fixing portion.

[0024] According to embodiment 8, even when affected by the curvature of the buttocks, the length of the rear support portion in the lateral direction is ensured. Therefore, the absorbent pad also maintains its wide shape. In addition, the area on which the diaper is supported by the support portion is ensured, allowing it to fit snugly against the wearer. Therefore, leakage of excrement can be suppressed.

[0025] (Aspect 9) A garment capable of supporting an absorbent pad or diaper as described in any of aspects 1 to 8, wherein, in the unfolded state, the length of the upper end of the back panel in the left-right direction is longer than the length of the upper end of the front panel in the left-right direction.

[0026] According to embodiment 9, the back of the garment is pulled to the front and the first engagement portion engages, so the rear support portion is also attached in a widened state in the left-right direction. As a result, the absorbent pad also fits snugly against the wearer in a wide state. In addition, an area is secured for the diaper to be supported by the support portion, allowing it to fit snugly against the wearer. Thus, leakage of excrement can be suppressed. Furthermore, the first engagement portion can be engaged on the front of the wearer, improving the ease of attaching the garment and the absorbent pad or diaper used in conjunction with it.

[0027] (Aspect 10) Clothing capable of supporting an absorbent pad or diaper as described in any of aspects 1 to 9, wherein in the unfolded state, the left and right side edges of the support portion are curved inward in the left and right direction from both ends in the longitudinal direction of the support portion toward the center.

[0028] According to embodiment 10, the force of the wearer closing their legs is less likely to be transmitted to the supporter portion, making it easier to maintain the state in which the supporter portion is spread out in the left-right direction. As a result, the absorbent pad also maintains a wide state. In addition, an area of ​​the diaper supported by the supporter portion is secured, allowing it to fit snugly against the wearer. Thus, leakage of excrement can be suppressed. Furthermore, the left-right side of the upper end of the supporter portion, near the engagement point of the first engagement portion, is inclined, making it easier to pull up the crotch area of ​​the supporter portion while spreading it outward in the left-right direction. As a result, the absorbent area of ​​the absorbent pad in the crotch area can be secured. In addition, an area of ​​the diaper supported by the supporter portion can be secured in the crotch area. Thus, leakage of excrement can be suppressed.

[0029] (Aspect 11) Clothing capable of supporting an absorbent pad or diaper as described in any of aspects 1 to 10, wherein at least a portion of the waist portion of the lower main body is expandable in the left-right direction, and the support surface of the supporter portion is provided with an engagement portion for the pad or diaper that can engage with the non-skin side of the absorbent pad or diaper.

[0030] According to embodiment 11, the absorbent pad or diaper is fixed to the support part, making it less susceptible to the effects of stretching and contracting of the waist part. Therefore, the absorbent pad is less likely to come off the support part, and displacement or unintended deformation of the absorbent pad can be suppressed. In addition, it is possible to prevent unintended deformation (such as the formation of wrinkles) of the diaper due to the effects of stretching and contracting of the waist part, and gaps between the diaper and the wearer are less likely to occur. Therefore, leakage of excrement can be suppressed.

[0031] (Aspect 12) Clothing capable of supporting an absorbent pad or diaper as described in Aspect 11, wherein the support portion has an elasticity region on the left-right side portion that is larger in the vertical direction than the central portion, and the engagement portion of the pad or diaper is provided on the inside in the left-right direction of the elasticity region.

[0032] According to embodiment 12, the absorbent pad or diaper becomes less susceptible to the effects of stretching in the stretchable area. Therefore, the absorbent pad is less likely to come off the support part, and displacement or unintended deformation of the absorbent pad can be suppressed. In addition, it is possible to prevent the diaper from being affected by the stretchable area and causing unintended deformation (such as the formation of wrinkles), and gaps between the diaper and the wearer are less likely to occur. Therefore, leakage of excrement can be suppressed.

[0033] ===First Embodiment=== As an example of the "clothing capable of supporting an absorbent pad or diaper" according to the present invention, the first embodiment will be described using infant trousers (hereinafter also referred to as "trousers") as an example.

[0034] <<Basic Structure of Trousers 1>> Figure 1 is a perspective view showing Trousers 1 in a worn state. Figure 2 is a schematic plan view of Trousers 1 in an expanded state in the vertical direction, as seen from the skin side. As shown in Figure 2, the "expanded state" in the vertical direction of the lower main body portion 10 and the support portion 20 means that both sides in the left-right direction of the lower main body portion 10 and the support portion 20 are separated, and the support portion 20 and the lower main body portion 10 are stretched out without wrinkles. If the sides of the lower main body portion or the support portion are detachably engaged by an engaging portion, the engaging portion is removed and separated. If the sides are sewn together, the left-right side ends of the lower main body portion or the support portion are cut with scissors or the like to separate them. However, if the lower main body portion 10 is sewn in a three-dimensional manner and there are parts of the lower main body portion 10 that cannot be laid flat (for example, the leg portion), or if the vertical (longitudinal) lengths of the support portion 20 and the lower main body portion 10 are different, the lower main body portion 10 may be partially loose, although this is not shown in Figure 2. Furthermore, the stretched state refers to the state in which the part made of elastic fabric is spread out without any load and without wrinkles, and in the case of the part to which an elastic member is attached to the fabric, it refers to the state in which the fabric is stretched so that the wrinkles caused by the elastic member disappear, that is, the state in which the dimensions of the fabric are stretched to match or close to the dimensions of the fabric alone.

[0035] As shown in Figure 1, the trousers 1, when worn, have mutually orthogonal vertical, left-right, and front-back directions, and have a waist opening BH and a pair of leg openings LH. The upper side in the vertical direction corresponds to the waist opening BH side, and the lower side corresponds to the crotch side. The front side in the front-back direction corresponds to the wearer's abdominal side, and the back side corresponds to the wearer's back side. As shown in Figure 2, the unfolded trousers 1 have mutually orthogonal longitudinal, left-right, and thickness directions. The longitudinal direction corresponds to the vertical direction in the worn state. In the thickness direction, the inner side closer to the wearer's skin is called the skin side, and the outer side on the opposite side is called the non-skin side.

[0036] Trousers 1 have a lower main body portion 10 and a support portion 20. The lower main body portion 10 is trouser-shaped and comprises a front body 11 and a back body 12, and is worn on the lower body of the wearer. The support portion 20 is provided on the skin side in the thickness direction of the lower main body portion 10 and has a support surface (skin side) 20s for supporting an absorbent pad.

[0037] In the case of infant trousers 1, an absorbent pad capable of absorbing and retaining urine and feces is supported by a supporter portion 20 and worn. The configuration of the absorbent pad used in conjunction with trousers 1 is not particularly limited. For example, it may be a disposable absorbent pad comprising a liquid-permeable surface sheet (nonwoven fabric, etc.), a liquid-impermeable back sheet (resin film, etc.), and an absorbent core (pulp fiber, etc.) provided between them that can absorb excretory fluids, or it may be a reusable absorbent pad that can be washed.

[0038] Furthermore, on one side in the left-right direction and the other side, the lower main body portion 10 and the support portion 20 are expandable in the front-back direction. The lower main body portion 10 has engaging portions 30 on both sides in the left-right direction so that the front body portion 11 and the back body portion 12 overlap, and so that the front body portion 11 and the back body portion 12 are detachably engaged. In other words, in the worn state (Figure 1), both sides in the left-right direction of the front body portion 11 and both sides in the left-right direction of the back body portion 12 of the lower main body portion 10 are connected by the engaging portions 30. In the expanded state (Figure 2), the engaging portions 30 are released, and all of both sides in the left-right direction of the front body portion 11 are separated from all of both sides in the left-right direction of the back body portion 12 in the front-back direction, and the front body portion 11 and the back body portion 12 are expanded side by side in the vertical direction.

[0039] On the other hand, even when worn, the left and right sides of the front portion of the supporter portion 20 are not connected to the left and right sides of the rear portion. Therefore, the two-fold portion of the supporter portion 20 is opened vertically to unfold it into a planar shape. However, it is not limited to the above, and the left and right sides of the front portion of the supporter portion 20 and the left and right sides of the rear portion may be configured to be removable and re-engaged. Furthermore, the supporter portion 20 may have no left and right sides connected, as in this embodiment, or it may have a shape in which the length of the connected sides when worn is short (briefs type), or it may have a shape in which the length of the connected sides when worn is long (boxer type, trunks type).

[0040] The trousers 1 (lower main body member 10 and supporter part 20) are made of cloth and are formed from reusable cloth (sheet member). Examples of cloth that make up the trousers 1 include "woven fabric" or "knitted fabric". "Woven fabric" is a fabric constructed in a flat surface by intersecting weft threads at right angles to a large number of warp threads arranged in parallel, and an example of such fabric is called "woven cloth". On the other hand, "knitted fabric" is a fabric constructed in a flat surface by making loops from yarn and connecting other loops to these loops, and an example of such fabric is called "knit". The fibers that make up the cloth are not particularly limited, and examples include natural fibers such as cotton and silk, synthetic fibers such as polyester, polyurethane, nylon and acrylic, semi-synthetic fibers such as acetate and regenerated fibers such as rayon, and these may be used individually or in combination. However, the trousers 1 are not limited to being made of cloth and may be formed from materials other than cloth.

[0041] The lower main body portion 10 has a waist portion 10W that stretches in the left-right direction, at least in part, and a lower main body portion 10L located below the waist portion 10W. Due to the stretchable waist portion 10W, the lower main body portion 10 fits according to the wearer's waist circumference, preventing the trousers 1 from slipping down and preventing tightness around the wearer's waist. In this embodiment, the waist portion 10W is made of a stretchable fabric to provide elasticity. However, it is not limited to this, and elasticity may also be provided to the waist portion 10W by arranging an elastic member such as flat rubber.

[0042] The elongation rate in the lateral direction of the stretchable area in the waist portion 10W (elongation rate when pulled with a predetermined force) is preferably 120% or more, more preferably 125% or more. The elongation rate can be measured by a well-known method. Specifically, a sample piece is cut from the target area. The sample piece is rectangular in shape, and it is desirable that the "length in the stretching direction (in this case, the lateral direction)" is "100 mm + the gripping width of the chuck (approximately 10 mm each at the top and bottom)" and the "width perpendicular to the stretching direction" is "25 mm", but the size can be appropriately changed depending on the size of the target area. Then, using a tensile testing machine (for example, Instron 5965 Model or equivalent), the distance between the chucks is widened at a tensile speed of 100 mm / min, and the elongation rate is determined when the sample piece is pulled in the stretching direction with a force of 1 N / 25 mm, that is, with a force of 1 N on a sample width of 25 mm. The initial distance between the chucks before the test (e.g., 100 mm) corresponds to the length before tension (G0), and the distance between the chucks when stretched with a predetermined force (1 N / 25 mm) corresponds to the length after tension (G1). Preferably, the elongation rate (= G1 / G0) is determined for multiple (e.g., n=5) sample pieces, and the average value is calculated. However, the method is not limited to the above, and the elongation rate of the stretched region may be less than 120%.

[0043] <<Regarding the lower main body part 10>> Figure 3 is a view of the folded trousers 1 from the front. Figure 4 is a view of the folded trousers 1 from the back. Figure 5 shows the process of setting the absorbent pad 40 in the supporter part 20.

[0044] The double-folded state is achieved by folding the skin side inward at the longitudinal center CL of the lower body part 10, aligning the centers C in the left-right direction at the upper ends of the front body part 11 and the back body part 12, removing the engaging part 30, spreading the front body part 11 and the back body part 12 in the left-right direction, and extending the lower body part 10. When one side part in the left-right direction of the lower body part 10 is sewn (not shown), it is in a sewn state. Also, the state of extending the lower body part 10 means that, regardless of the supporter part 20, the lower body part 10 is spread without wrinkles. When the stretching area of the lower body part 10 is made of stretchable fabric, it is in a state of being spread without wrinkles without applying a load. When an elastic member is attached to the stretching area, it is in a state of being extended so that the wrinkles generated in the fabric by the elastic member disappear.

[0045] In the lower body part 10 of the present embodiment, both side parts in the left-right direction can be unfolded in the front-back direction, and engaging parts 30 are provided on each of the both side parts in the left-right direction of the lower body part 10. The engaging part 30 on one side in the left-right direction and the engaging part 30 on the other side in the left-right direction each have a first engaging part 31, a second engaging part 32, and a third engaging part 33. The first engaging part 31 is located above the upper end fixing part F20 of the supporter part 20 with respect to the lower body part 10. The second engaging part 32 is located below the first engaging part 31. The third engaging part 33 is located between the first engaging part 31 and the second engaging part 32 in the vertical direction.

[0046] The first engaging part 31 is a combination of a male member of a surface fastener (a member provided with hooks) and a female member of a surface fastener (a member provided with loops that engage with the hooks). One of the male member and the female member of the surface fastener is provided on the front body part 11, and the other is provided on the back body part 12. For the sake of explanation, the first engaging part 31 provided on the front body part 11 is also referred to as the front-side first engaging part 31F, and the first engaging part 31 provided on the back body part 12 is also referred to as the back-side first engaging part 31B. Specifically, square-shaped front-side first engaging parts 31F are provided one by one on each of the side parts on one side and the other side in the left-right direction on the non-skin side surface of the waist part 10W of the front body part 11. Also, square-shaped back-side first engaging parts 31B are provided one by one on each of the side parts on one side and the other side in the left-right direction on the skin side surface of the waist part 10W of the back body part 12.

[0047] The second engaging portion 32 and the third engaging portion 33 are each a combination of a male button of a snap button and a female button that fits into it. As the second engaging portion 32, one of the male button and the female button is provided on the front body portion 11, and the other is provided on the back body portion 12. The second engaging portion 32 on the front body portion 11 is also referred to as the front-side second engaging portion 32F, and the second engaging portion 32 on the back body portion 12 is also referred to as the back-side second engaging portion 32B. Similarly, as the third engaging portion 33, one of the male button and the female button is provided on the front body portion 11, and the other is provided on the back body portion 12. The third engaging portion 33 on the front body portion 11 is also referred to as the front-side third engaging portion 33F, and the third engaging portion 33 on the back body portion 12 is also referred to as the back-side third engaging portion 33B.

[0048] As shown in FIG. 1, in the pants 1 of the present embodiment, the non-skin side surface of the front body portion 11 and the skin side surface of the back body portion 12 overlap so as to abut. However, it is not limited to this. For example, the skin side surface of the front body portion 11 and the non-skin side surface of the back body portion 12 may abut and overlap, or the skin side surfaces of the front body portion 11 and the back body portion 12, or the non-skin side surfaces of the front body portion 11 and the back body portion 12 may abut and overlap.

[0049] As shown in FIG. 5, the user (such as a caregiver) expands the lower body portion 10 and the supporter portion 20 in the vertical direction (front-back direction), places the absorption pad 40 on the support surface (skin side surface) 20s for supporting the absorption pad 40, and engages the engaging portion 30 of the lower body portion 10, thereby completing the wearing of the pants 1 on the wearer (infant).

[0050] The lower body portion 10 has a pants shape with long sides in the left-right direction, and the pants 1 has a shape different from that of a general cloth diaper cover, that is, a shape similar to underwear such as briefs. Therefore, the pants 1 can be worn not as underwear but as home clothes or outdoor clothes, and there is no need to wear additional clothing over the pants 1. Thus, according to the pants 1 of the present embodiment, compared with the case of using a general cloth diaper cover (that is, when wearing pants after setting the absorption pad 40 in a cloth diaper cover), the wearing process is simplified, and the replacement of the absorption pad 40 can also be easily performed. Further, according to the pants 1 of the present embodiment, sweating can be suppressed by the amount corresponding to not wearing a cloth diaper cover, and it can be comfortably worn even in hot seasons.

[0051] In particular, the lower main body portion 10 and the support portion 20 can be unfolded vertically (front-to-back) on both sides in the left-to-right direction, resulting in a shape similar to a tape-type disposable diaper. Therefore, after placing the unfolded trousers 1 with the absorbent pad 40 set under the back of the wearer (infant) in a supine position, the trousers 1 are folded in half and placed against the wearer's abdomen, and the engaging portion 30 is engaged to complete the wearing process. The user can put on the trousers 1 without having to pass the wearer's legs through the waist opening of the trousers to the leg opening.

[0052] Furthermore, using the absorbent pad 40 reduces the amount of waste compared to using disposable diapers, thereby reducing the environmental burden. Using reusable absorbent pads in conjunction with the diaper can further reduce waste. On the other hand, using disposable absorbent pads reduces the number of washes required. In the trousers 1 of this embodiment, a diaper cover is not used, and the trousers 1 directly support the absorbent pad 40, thus reducing the burden on the user.

[0053] In this embodiment, the lower body portion 10 is given as an example of a trouser shape (a shape in which the left-right central part of the lower end of the front body 11 and the left-right central part of the lower end of the back body 12 are connected), but the lower body portion may be a skirt shape. In other words, the lower end of the front body and the lower end of the back body may be separated, and in the unfolded state, only the support portion 20 may be continuous in the longitudinal direction. Also, culottes are included in the trouser shape. Furthermore, although the trousers 1 in this embodiment are shorts, they may also be long trousers.

[0054] Furthermore, it is sufficient that the lower main body and support portion can be unfolded in the front-to-back direction on at least one side in the left-to-right direction. For example, the side of the front body and the side of the back body on the other side in the left-to-right direction may be sewn together (connected inseparably). In this case, the support portion may or may not be sewn together on the other side in the left-to-right direction. In this case, the user can easily put on the trousers by passing one leg through the waist opening of the trousers to the leg opening, and then engaging the engaging portion while wrapping the front and back body around the opposite leg. Also, the condition of the absorbent pad (e.g., whether or not there is excretion) can be easily checked by releasing the engaging portion on one side in the left-to-right direction without having to take off the trousers.

[0055] Furthermore, since the first engaging portion 31 is a hook-and-loop fastener with relatively weak engagement force, it becomes easier to adjust the engagement position of the first engaging portion 31 according to the wearer's waist circumference. Since the second engaging portion 32 is a snap button with relatively strong engagement force, it becomes difficult for the second engaging portion 32 to come undone due to the wearer's movements. However, the first engaging portion 31 may be an engaging portion other than a hook-and-loop fastener, and the second engaging portion 32 and the third engaging portion 33 may be engaging portions other than snap buttons. Examples of engaging portions other than hook-and-loop fasteners and snap buttons include magnetic buttons, buttons and buttonholes, hooks and eyelets, etc., and are not particularly limited as long as they are used in clothing.

[0056] Furthermore, the first engaging portion 31, the second engaging portion 32, and the third engaging portion 33 are each spaced apart in the vertical direction. Therefore, compared to cases where highly rigid engaging portions, such as zippers, are continuously provided in the vertical direction, irritation to the wearer's skin can be reduced, and the functionality of the clothing can be improved. Also, compared to cases where the third engaging portion 33 is not provided on the lower main body portion 10, the spacing between the engaging portions 30 in the vertical direction becomes narrower, making it more difficult to see the wearer's skin (legs) from the outside of the trousers 1. However, the above is not limited to the above, and the third engaging portion 33 may not be provided on the lower main body portion 10, or four or more engaging portions 30 may be arranged on one side in the left-right direction with spacing between them in the vertical direction.

[0057] <<Regarding the supporter portion 20>> Figure 6 is a schematic diagram of the trousers 1 being worn, viewed from the side. Figure 7 is a schematic plan view showing the vertically unfolded state of the lower main body portion 10 and the supporter portion 20. Figures 8A to 8C are explanatory diagrams of the positional relationship between the supporter portion 20 and the first engaging portion 31. Figures 9A and 9B are explanatory diagrams of the positional relationship between the supporter portion 20' and the first engaging portion 31' in trousers of a comparative example different from this embodiment. Figures 10A and 10B are explanatory diagrams of the positional relationship of modified examples of the supporter portion 20 and the first engaging portion 31. Figure 8A is a schematic diagram of the trousers 1 being worn, viewed from above. Figures 8B, 9A, and 10A are schematic diagrams showing one side in the left-right direction of trousers in a folded state. Figures 8C, 9B, and 10B are schematic diagrams showing the engagement point of the first engaging portion 31 (31').

[0058] As shown in Figure 7, the upper ends of the front and rear supporter portions 20 are attached to and fixed to the lower main body portion 10 by upper end fixing portions F20, respectively. The first engaging portion 31 of the engaging portion 30 is located above the upper end fixing portion F20. In this embodiment, the supporter portion 20 is not fixed to the lower main body portion 10 except for the upper end fixing portion F20.

[0059] Because there are fewer fixing points between the lower main body 10 and the supporter part 20, the supporter part 20 is less affected by the movement of the lower main body 10. Therefore, it is easier to maintain a state in which the absorbent pad 40 supported by the supporter part 20 is in close contact with the wearer's crotch, and leakage of excrement can be suppressed. In particular, between the upper end fixing parts F20 on the front and rear sides, if the length of the supporter part 20 in the longitudinal direction is shorter than the length of the lower main body 10, the supporter part 20 is positioned above the lower main body 10, as shown in Figure 6. Therefore, the close contact of the absorbent pad 40 is improved. On the other hand, the lower main body 10 is less likely to dig into the wearer's crotch. Therefore, the design of the trousers 1 (lower main body 10) is enhanced, the underwear-like appearance is reduced, and the trousers 1 can be worn as loungewear or outerwear. However, it is not limited to the above, and a part of the supporter part 20 other than the upper end fixing part F20 may be fixed to the lower main body 10.

[0060] As shown in Figure 7, in the vertically extended state of the lower main body portion 10 and the support portion 20, the upper end fixing portion F20 on at least one side in the front-rear direction extends outward in the left-right direction beyond the inner end of the first engagement portion 31 on one side in the left-right direction. In this embodiment, the front first engagement portion 31F is located inward in the left-right direction beyond the rear first engagement portion 31B. In this case, the inner end Efa of the front first engagement portion 31F on one side in the left-right direction is the "inner end of the first engagement portion 31 on one side in the left-right direction". In this embodiment, as shown in Figures 7 and 8B, the rear upper end fixing portion F20 (i.e., the rear support portion 20) extends outward in the left-right direction beyond the inner end Efa of the front first engagement portion 31F.

[0061] Suppose, as in the comparative example in Figure 9A, the support portion 20' is located inside the inner end Efa of the first engagement portion 31' in the left-right direction. In this case, when the first engagement portion 31' is engaged, as shown in Figure 9B, the support portion 20' is located at a distance W1 (in the left-right or waist direction) from the engagement point of the first engagement portion 31'. In contrast, with the trousers 1 of this embodiment, compared to the comparative example, the rear support portion 20 is located closer to or overlaps with the engagement point of the first engagement portion 31. As shown in Figures 8A and 8C, the rear support portion 20 of this embodiment overlaps with the engagement point of the first engagement portion 31 in the waist direction. Therefore, one side of the rear support portion 20 in the left-right direction is pulled towards the wearer's side along with the back panel 12 when the trousers 1 are worn. Thus, the rear support portion 20 is worn in a state where it is spread out in the left-right direction. Therefore, the absorbent pad 40 supported by the rear support portion 20 can also be wide enough to fit snugly against the wearer.

[0062] Furthermore, at the engagement point of the first engagement portion 31, the front body 11 and the back body 12 pull against each other and are easily fixed at the wearer's hip bones, reducing movement in the waist direction (left-right direction). As a result, one side of the rear support portion 20 in the left-right direction is less likely to shift position while wearing the trousers 1. For example, even if the wearer closes their legs and the crotch area of ​​the support portion 20 receives an inward force in the left-right direction, the rear support portion 20 can resist that force, and the state in which the rear support portion 20 is spread in the left-right direction is maintained. The absorbent pad 40 also maintains its wide state. As a result, the absorbent pad 40 has a sufficient absorbent area to receive excrement. In addition, deformation of the absorbent pad 40 due to the wearer closing their legs (for example, the occurrence of vertical wrinkles along the longitudinal direction) can be suppressed. In addition, deformation due to the absorbent pad 40 coming off the support portion 20 (for example, folding or curling of the absorbent pad 40) can be suppressed. This allows the absorbent pad 40 to firmly receive the excrement, preventing leakage from the trousers 1. It also reduces discomfort during wear caused by wrinkles or folds in the absorbent pad 40.

[0063] In this embodiment, the trousers 1 have one first engaging portion 31 on each side in the left-right direction, but multiple first engaging portions 31 may be arranged in a row with spacing between them in the left-right direction. In this case, the inner end of the innermost (on the other side) first engaging portion 31 among the multiple first engaging portions 31 arranged on one side in the left-right direction of the lower body portion 10 is the "inner end of the first engaging portion 31 on one side in the left-right direction." Also, the first engaging portion 31 may be provided on only one of the front body 11 and the back body 12, and not on the other. For example, one of the front body 11 and the back body 12 may be provided with a hook-and-loop fastener as the first engaging portion 31, and the other may be made of a fabric that can engage with the hook-and-loop fastener. In this case, the inner end of the first engaging portion 31 provided on one side in the left-right direction of one of the front body 11 and the back body 12 is the "inner end of the first engaging portion 31 on one side in the left-right direction."

[0064] Preferably, in the vertically extended state of the lower main body portion 10 and the support portion 20, the upper end fixing portion F20 on one side in the front-rear direction is on the same side in the front-rear direction and extends outward in the left-right direction beyond the inner end of the first engaging portion 31 on one side in the left-right direction. In this embodiment, the rear upper end fixing portion F20 is on the same rear side and extends outward in the left-right direction beyond the inner end Eba of the rear first engaging portion 31B on one side in the left-right direction.

[0065] This makes it easier for the rear support portion 20 to overlap with the engagement point of the first engagement portion 31. For example, as shown in Figure 8C, when the portion of the rear first engagement portion 31B that overlaps with the support portion 20 engages with the front first engagement portion 31F, the support portion 20 overlaps with the engagement point of the first engagement portion 31. As a result, one side of the rear support portion 20 in the left-right direction is pulled towards the wearer's armpit. Therefore, the rear support portion 20 is worn in a state that is spread out in the left-right direction, and this spread state is easily maintained. Thus, unintended deformation of the absorbent pad 40 and detachment from the support portion 20 can be suppressed, and leakage of excrement can be suppressed.

[0066] However, the invention is not limited to the above. As shown in the modified examples in Figures 10A and 10B, the upper end fixing portion F20 on one side in the front-rear direction (in this case, the rear side) may be located inward in the left-right direction from the inner end Eba of the first engaging portion 31 on the same side in the front-rear direction (the rear side), and may extend outward in the left-right direction from the inner end Efa of the first engaging portion 31 on the opposite side in the front-rear direction (the front side). In this case as well, compared to the comparative example (Figure 9B), the support portion 20 is more likely to be located closer to the engagement point of the first engaging portion 31 (a distance of W2 from the engagement point) (W2 < W1). Therefore, the support portion 20 is more likely to be attached in a state that is spread out in the left-right direction, and that spread state is more likely to be maintained.

[0067] Furthermore, the rear support portion 20 is more prone to shifting inward in the left-right direction due to the curvature of the buttocks compared to the front portion. Therefore, in the vertically unfolded state of the lower main body portion 10 and the support portion 20 (Figure 7), it is preferable that the rear upper end fixing portion F20 (rear support portion 20) extends outward in the left-right direction beyond the inner end Eba of one of the rear first engagement portions 31B in the left-right direction.

[0068] As described above, one side of the rear support portion 20 in the left-right direction is more likely to overlap with the engagement point of the first engagement portion 31. Therefore, the rear support portion 20 is worn in a state that is spread out in the left-right direction, and this spread state is more likely to be maintained. In addition, it is possible to prevent one side of the rear support portion 20 in the left-right direction from shifting inward in the left-right direction due to the curvature of the buttocks. As a result, unintended deformation of the absorbent pad 40 and detachment from the support portion 20 can be prevented, and leakage of excrement can be prevented. Furthermore, discomfort during wear can be prevented.

[0069] More preferably, in the vertically extended state of the lower main body portion 10 and the support portion 20 (Figure 7), the rear upper end fixing portion F20 (rear support portion 20) extends outward in the left-right direction beyond the inner end Ebb of the other rear first engagement portion 31B in the left-right direction.

[0070] This makes it easier for both sides of the rear support portion 20 in the left-right direction to overlap with the engagement points of the first engagement portion 31. Therefore, the rear support portion 20 is worn in a state where it is spread out on both sides in the left-right direction, and this spread state is easier to maintain. In addition, it is possible to prevent both sides of the rear support portion 20 in the left-right direction from shifting inward in the left-right direction relative to the curvature of the buttocks. Therefore, leakage of excrement can be further suppressed, and discomfort during wear can be further reduced. The trousers 1 of this embodiment have a symmetrical shape in the left-right direction. However, it is not limited to this, and in the left-right direction, only one side of the rear support portion 20 may extend outward beyond the inner end of the first engagement portion 31 on one side, and the other side of the rear support portion 20 may be located inward beyond the inner end of the first engagement portion 31 on the other side.

[0071] Figure 11 is an explanatory diagram of a modified example of trousers 1, and is a schematic plan view showing the front portion of the lower main body portion 10 and the support portion 20 in an expanded state in the vertical direction. In the trousers 1 shown in Figure 7, the front support portion 20 is located inside the inner end Efa of the first engagement portion 31 (front first engagement portion 31F) in the left-right direction. However, it is not limited to this, and as in the modified example of trousers in Figure 11, the front support portion 20 may extend outward in the left-right direction beyond the inner end Efa of one side of the first engagement portion 31 (front first engagement portion 31F) in the left-right direction. In Figure 11, the front support portion 20 extends outward in the left-right direction beyond the inner ends Efa and Efb of the first engagement portion 31 on both sides in the left-right direction. As a result, the left-right side portions of the front support portion 20 are located near or overlap with the engagement points of the first engagement portion 31, so that the front support portion 20 is worn in a spread-out state in the left-right direction, and that spread-out state is easier to maintain. Therefore, leakage of excrement and discomfort during wear can be suppressed even on the front side. In addition, although not shown in the figures, the front support portion 20 may extend outward from the inner end of the first engagement portion 31 in the left-right direction, and the rear support portion 20 may be located inward from the first engagement portion 31 in the left-right direction.

[0072] Figure 12 is an explanatory diagram of the expandable / contractible region S1 of the supporter portion 20, and is a schematic plan view showing the vertically expanded state of the lower main body portion 10 and the supporter portion 20. It is preferable that the supporter portion 20 has an expandable / contractible region S1 on the left-right side portion that is larger in the vertical direction than the central portion Sc. In this embodiment, the supporter portion 20 has expandable / contractible regions S1 on both sides in the left-right direction, but it is sufficient that the expandable / contractible region S1 is provided on at least one side in the left-right direction.

[0073] High vertical elasticity means that the elongation rate (length under tension / length in the natural state (before tension) = G1 / G0) when pulled with a predetermined force (e.g., 1N) in the vertical direction is large. In this embodiment, the stretchable region S1 and the central part Sc are made of different fabrics, and the stretchable region S1 is made of a fabric that is highly elastic and easily stretched.

[0074] This makes it easier for the side portion (stretchable area S1) of the support portion 20 to adhere closely to the wearer's legs. Therefore, the support portion 20 follows the movement of the wearer's legs, preventing displacement of the absorbent pad 40 and suppressing leakage of excrement. In addition, the left and right sides of the upper end of the support portion 20, which are close to the engagement point of the first engagement portion 31, can be easily pulled up while spreading the crotch area of ​​the support portion 20 outward in the left and right directions via the stretchable area S1. Therefore, it is possible to prevent the crotch area of ​​the support portion 20 from moving too far inward in the left and right directions when the wearer closes their legs. Therefore, the absorption area of ​​the absorbent pad 40 in the crotch area can be secured, suppressing leakage of excrement. On the other hand, the central portion Sc, which has less elasticity, is easier to maintain in a flat state. Therefore, it becomes easier to set the absorbent pad 40 in the central portion Sc, and the absorbent pad 40 can be stably supported in the central portion Sc.

[0075] The "comparison of elasticity (elongation)" can be performed using a well-known method. Specifically, a sample piece is cut from the target area (stretchable region S1 and central part Sc). Alternatively, if the fabric constituting the target area can be prepared, a sample piece may be formed from that fabric. The sample piece should be rectangular in shape, with a "length in the elongation direction (here, the vertical direction)" of "100 mm + the gripping width of the chuck (approximately 10 mm each at the top and bottom)" and a "width perpendicular to the elongation direction" of "25 mm". However, the size of the sample piece should be appropriately changed depending on the size of the target area. Then, using a tensile testing machine (for example, Instron 5965 Model or equivalent), the distance between the chucks is widened at a tensile speed of 100 mm / min, and the elongation when the sample piece is pulled in the elongation direction with a force of 1 N / 25 mm, that is, with a force of 1 N on a sample width of 25 mm, is determined. The initial distance between the chucks before the test (e.g., 100 mm) corresponds to the length (G0) before tension (natural state), and the distance between the chucks when stretched with a predetermined force (1 N / 25 mm) corresponds to the length after tension (G1). Preferably, the elongation rate (= G1 / G0) is determined for multiple (e.g., n=5) sample pieces, and the average value is calculated.

[0076] Preferably, the stretchable region S1 has a high-shrinkage region S2 that can be contracted in the vertical direction, and a low-shrinkage region S3 located inside the high-shrinkage region S2 in the left-right direction, where the vertical shrinkage force is smaller than that of the high-shrinkage region S2. In this embodiment, the low-shrinkage region S3 is made of a highly elastic fabric (a fabric that stretches easily), and the high-shrinkage region S2 has rubber (for example, flat rubber) attached to the same fabric as the low-shrinkage region S3. Therefore, the high-shrinkage region S2 is less stretchable but has a greater shrinkage force compared to the low-shrinkage region S3. Conversely, the low-shrinkage region S3 is more stretchable but has a smaller shrinkage force compared to the high-shrinkage region S2.

[0077] As a result, the highly contractile region S2 adheres firmly to the wearer's legs, preventing the absorbent pad 40 from shifting position and suppressing leakage of excrement. In the lower contractile region S3 inside it, the contraction force is moderately suppressed, which suppresses the contraction of the absorbent pad 40 while allowing it to adhere closely to the wearer's body. Therefore, leakage of excrement can be suppressed.

[0078] The "comparison of contraction force" can be performed using a well-known method. Specifically, sample pieces are formed from the target area (high contraction region S2 and low contraction region S3). The method for forming the sample pieces is the same as when measuring elasticity (elongation). The size of the sample piece should preferably be "length in the contraction direction (here, vertical direction) of 100 mm + chuck gripping width (approximately 10 mm each vertically)" and "width perpendicular to the contraction direction" of 25 mm. A tensile testing machine (for example, Instron 5965 Model or equivalent) is used. At a tensile speed of 100 mm / min, the distance between the chucks is increased, and the sample piece is stretched from its natural state to a predetermined elongation state (elongation state with elongation rate A%). Then, at the same speed, the distance between the chucks is decreased to an elongation state lower than the predetermined elongation state (for example, elongation rate A - 20%), and the load (force that causes the sample piece to return to its original length: N / 25 mm) is measured and compared as the contraction force. Preferably, the contraction force is determined for multiple (e.g., n=5) sample pieces, and the average value is calculated.

[0079] In the vertically unfolded state of the lower main body portion 10 and the support portion 20, as shown in Figure 12, it is preferable that the maximum length in the left-right direction of the low-shrinkage region S3 provided in at least one end region 20A, 20C of the three regions 20A to 20C obtained by dividing the support portion 20 into three equal parts in the longitudinal direction is longer than the maximum length in the left-right direction of the low-shrinkage region S3 provided in the central region 20B. In the support portion 20 of this embodiment, the maximum length W5 in the left-right direction of the low-shrinkage region S3 of the rear end region 20A is longer than the maximum length W3 in the left-right direction of the low-shrinkage region S3 of the central region 20B (W5 > W3). Also, the maximum length W4 in the left-right direction of the low-shrinkage region S3 of the front end region 20C is longer than the maximum length W3 in the left-right direction of the low-shrinkage region S3 of the central region 20B (W4 > W3). Note that the lengths are compared in the low-shrinkage region S3 on the same side in the left-right direction. Furthermore, if low-shrinkage regions S3 are provided on both sides of the supporter portion 20 in the left-right direction, it is sufficient that the above length relationship is satisfied on at least one side in the left-right direction.

[0080] As described above, at the upper end portion (end regions 20A, 20C) of the support portion 20, the low-contraction region S3, which has a long length in the left-right direction, allows the left-right sides of the absorbent pad 40 to stand up and fit snugly, wrapping around the curves of the wearer's buttocks and abdomen. Therefore, gaps between the wearer and the absorbent pad 40 are less likely to occur, and leakage of excrement can be suppressed.

[0081] Furthermore, the support portion 20 of this embodiment has a shape in which the central part in the longitudinal direction is constricted, and the length of the central region 20B in the left-right direction is shorter than that of the end regions 20A and 20C. In this case, by shortening the length of the low-shrinkage region S3 in the left-right direction in the central region 20B, the length of the less elastic central portion Sc in the left-right direction can be secured. This makes it easier to set the absorbent pad 40 in the central portion Sc, and the absorbent pad 40 can be stably supported in the central portion Sc.

[0082] Preferably, the area ratio of the low-shrinkage region S3 in the end region 20A or 20C of the supporter portion 20 (total area of ​​the low-shrinkage region S3 / total area of ​​the end region 20A or 20C) is greater than the area ratio of the low-shrinkage region S3 in the central region 20B (total area of ​​the low-shrinkage region S3 / total area of ​​the central region 20B). Also, the total area of ​​the low-shrinkage region S3 in the end region 20A or 20C of the supporter portion 20 is greater than the total area of ​​the low-shrinkage region S3 in the central region 20B. In these cases as well, the same effects as described above can be obtained.

[0083] As mentioned above, at least a portion of the waist portion 10W of the lower main body portion 10 stretches in the left-right direction. Therefore, the lower main body portion 10 fits according to the wearer's waist circumference, providing a comfortable fit and preventing the trousers 1 from slipping down. In this case, as shown in Figure 2, it is preferable that the left-right stretchability of the engagement region S4, where the first engagement portion 31 is provided, in the waist portion 10W of at least one of the front body portion 11 and the back body portion 12 is smaller than the left-right stretchability of the region S5 located inside the engagement region S4 in the left-right direction. Small left-right stretchability means that the elongation rate when pulled with a predetermined force (e.g., 1N) in the left-right direction is small. The stretchability (elongation rate) can be compared using the method described above with a tensile testing machine. In this embodiment, the entire waist portion 10W is made of the same fabric (a fabric that stretches easily), but the stretchability is suppressed by providing the first engagement portion 31, which is a hook-and-loop fastener, in the engagement region S4.

[0084] As described above, when the first engaging portion 31 is engaged, the area S5 inside the first engaging portion 31 stretches, and together with the waist portion 10W of the lower main body portion 10, the support portion 20 is also attached in a state that has spread in the left-right direction. Therefore, the absorbent pad 40 also fits closely to the wearer in a wide state, and leakage of excrement can be suppressed. On the other hand, since the engaging area S4 does not stretch easily, the engagement point of the first engaging portion 31 with respect to the wearer is easily fixed (for example, fixed at the hip bone), and displacement of the upper ends of the lower main body portion 10 and the support portion 20 can be suppressed.

[0085] As shown in Figure 7, in the vertically extended state of the lower main body portion 10 and the support portion 20, it is preferable that the left-right length W6 of the support portion 20 at the rear upper end fixing portion F20 is longer than the left-right length W7 of the support portion 20 at the front upper end fixing portion F20 (W6 > W7).

[0086] As described above, because the length W6 of the rear support portion 20 in the left-right direction is long, the length of the rear support portion 20 in the left-right direction is maintained even when affected by the curvature of the buttocks. Therefore, the absorbent pad 40 also maintains its wide state, and leakage of excrement can be suppressed. In addition, by covering the buttocks widely with the rear support portion 20, the user's (guardian's, etc.) anxiety about leakage can be reduced.

[0087] Furthermore, as shown in Figure 7, when the lower main body portion 10 and the support portion 20 are unfolded in the vertical direction, it is preferable that the length W8 in the left-right direction of the upper end 12E of the back body portion 12 is longer than the length W9 in the left-right direction of the upper end 11E of the front body portion 11 (W8 > W9).

[0088] As described above, when the trousers 1 are put on, the waist portion 10W of the back panel 12 is pulled from the back to the front, and the first engaging portion 31 is engaged. As a result, the rear support portion 20 is also worn in a state that is spread out in the left-right direction. Therefore, even if affected by the curvature of the buttocks, the left-right length of the rear support portion 20 is ensured. As a result, the absorbent pad 40 is also kept wide, and leakage of excrement can be suppressed. In addition, when a guardian puts the trousers 1 on a child lying on their back or facing a child, it becomes easier to engage the first engaging portion 31 on the front. It also becomes easier to engage the first engaging portion 31 when the wearer puts on the trousers 1 themselves. In particular, when both sides of the trousers 1 in the left-right direction are spread out in the up-down direction, it takes on a shape similar to a tape-type disposable diaper. Therefore, when the trousers 1 are placed under the back of a wearer lying on their back, the back panel 12 is easier to pull towards the abdomen, and the left and right sides of the back panel 12 are less likely to get caught under the back.

[0089] Furthermore, in the vertically extended state of the lower main body portion 10 and the support portion 20, it is preferable that the left and right side edges 20a of the support portion 20 are curved inward in the left and right direction from both ends in the longitudinal direction of the support portion 20 toward the center. In other words, it is preferable that the support portion 20 has a shape in which the length in the left and right direction is shorter in the center compared to both ends (a so-called hourglass shape).

[0090] This reduces the force applied to the crotch area of ​​the supporter portion 20 when the wearer closes their legs, making it less likely for the force of the wearer closing their legs to be transmitted to the upper end of the supporter portion 20, and making it easier to maintain the state in which the supporter portion 20 is spread out in the left and right directions. As a result, the absorbent pad 40 also maintains a wide state, and leakage of excrement can be suppressed. In addition, the left and right sides of the upper end of the supporter portion 20, which are close to the engagement point of the first engagement portion 31, are inclined, making it easier to pull up the crotch area of ​​the supporter portion 20 while spreading it outward in the left and right directions. As a result, it is possible to prevent the crotch area of ​​the supporter portion 20 from moving too far inward in the left and right directions when the wearer closes their legs. Thus, the absorbent area of ​​the absorbent pad 40 in the crotch area can be secured, and leakage of excrement can be suppressed.

[0091] Furthermore, as shown in Figure 12, the support surface 20s of the supporter portion 20 is provided with a pad engagement portion 21 (corresponding to, for example, the male member of a hook-and-loop fastener, or the engagement portion of a pad or diaper) that can engage with the non-skin side (for example, nonwoven fabric) of the absorbent pad 40. Therefore, the absorbent pad 40 is not fixed to the waist portion 10W of the lower main body portion 10, but is fixed to the supporter portion 20. Thus, the absorbent pad 40 is less affected by the waist portion 10W which expands and contracts due to the wearer's breathing and movements, and is less likely to come off the supporter portion 20. Consequently, displacement and unintended deformation of the absorbent pad 40 can be suppressed, and leakage of excrement can be suppressed.

[0092] In Figure 12, one rectangular pad engagement portion 21 is provided at each of the longitudinal ends of the support surface 20s of the support portion 20, but the shape, number, and arrangement of the pad engagement portions 21 are not particularly limited.

[0093] Preferably, the pad engagement portion 21 is provided inward in the left-right direction from the stretchable region S1 on the side of the support portion 20. By fixing the pad engagement portion 21 to the less stretchable central portion Sc, the absorbent pad 40 is less affected by the stretching and contracting of the stretchable region S1 and is less likely to come off the support portion 20. Therefore, displacement and unintended deformation of the absorbent pad 40 can be suppressed, and leakage of excrement can be suppressed. However, the support portion 20 does not necessarily have to have the pad engagement portion 21.

[0094] ===Second Embodiment=== Figures 13A and 13B are explanatory diagrams of the garment 100 in the second embodiment. The garment 100 has a lower main body portion 110 worn on the lower body, an upper main body portion 120 worn on the upper body, and a support portion 130 provided on the inside of the lower main body portion 110. The lower main body portion 110 and the support portion 130 have the same configuration as the trousers 1 described in the first embodiment, so a detailed explanation is omitted.

[0095] In garment 100, the back panel 122 of the upper body part 120 is connected to the back panel 110 of the lower body part 110. The upper body part 120 is expandable vertically on both sides in the left-right direction. That is, both sides of the front panel 121 and both sides of the back panel 122 of the upper body part 120 separate, and the front panel 121 and back panel 122 expand vertically. Engaging parts 123 (e.g., snap buttons) are provided on both sides of the front panel 121 and back panel 122 of the upper body part 120. With such garment 100, the upper body part 120 is worn by passing the wearer's head through the neck opening 124 provided in the upper body part 120, folding the front panel 121 downwards, and engaging the engaging parts 123. The lower body part 110 is worn using the method described in the first embodiment.

[0096] Thus, the garment capable of supporting the absorbent pad according to the present invention may be a one-piece garment (for example, a romper, a dress, etc.) in which a lower main body portion 110 worn on the lower body and an upper main body portion 120 worn on the upper body are connected. Furthermore, although an upper main body portion 120 that can be expanded in the vertical direction has been illustrated here, the upper main body portion may be a garment that can be expanded in the horizontal direction, or a garment that cannot be expanded.

[0097] ===Other Embodiments=== The embodiments described above are provided to facilitate understanding of the present invention and are not intended to limit its interpretation. The present invention can be modified and improved without departing from its spirit, and it goes without saying that the present invention includes equivalents thereof.

[0098] For example, while infant clothing was given as an example of clothing capable of supporting an absorbent pad or diaper, adult clothing may also be used. Furthermore, the absorbent pad supported by the clothing is not limited to absorbent pads that absorb urine or feces, but may also be a sanitary napkin or a panty liner.

[0099] In the first and second embodiments, embodiments in which the absorbent pad is supported by the support surface of the supporter portion are illustrated, but the invention is not limited to these embodiments. The support surface of the supporter portion in the first and second embodiments (for example, the support surface 20s of the supporter portion 20 shown in Figure 2 and the support surface of the supporter portion 130 shown in Figure 13A) can also function as a support surface for supporting a diaper. Specifically, examples of diapers include disposable tape-type diapers, disposable pant-type diapers, and disposable diapers in which one side in the width direction is tape-type and the other side is pant-type. Even when the supporter portion in the first and second embodiments supports a diaper, the diaper is supported by the supporter portion and can be closely fitted to the wearer. Therefore, effects such as suppressing leakage of excrement can be obtained, similar to when the supporter portion supports an absorbent pad.

[0100] Furthermore, if the lower main body portion 10 and the support portion 20 are expandable in the front-to-back direction on both sides in the left-to-right direction, as shown in Figure 2, the expanded tape-type diaper can be set into the support portion 20 and then placed under the back of the wearer in a supine position for wear.
