Description

Technical Field

[0001] The present disclosure relates to an absorbent article. Background Art

[0002] In the past, there is known a diaper (absorbent article) that is attached to the inside of a cloth underwear or other wearing article. For example, Patent Document 1 discloses a method of combining a diaper and a diaper cover having a shape substantially the same as the diaper.

[0005] Patent Document 1: Japanese Patent Application Laid-Open No. 8-215229 Summary of the invention

[0006] Problem that the invention aims to solve

[0007] Recently, from the perspective of SDGs (United Nations Sustainable Development Goals), the demand for reusable wearing articles such as those described above has increased. However, such wearing articles need to be washed when the wearer's excrement is attached, so the burden on the assistant who raises or cares for the wearer is large. Therefore, in order to suppress the side leakage of excrement from the absorbent article and prevent the excrement from being attached to the wearing article as much as possible, it is considered to make the absorbent article (specifically, the leg gathers of the absorbent article) as large as possible. However, since the wearing article and the absorbent article are separately constructed, if used for a long time, there is a concern that the leg gathers of the absorbent article that are in contact with the wearer's legs (mainly the inner part of the thigh) are pulled into the crotch of the wearer without being linked to the wearing article due to the movement of the wearer's legs (for example, the leg closing action of closing the legs from the open leg state). As a result, excrement is likely to leak from the side of the leg gathers of the absorbent article, and there is a concern that the wearing article (for example, the leg opening part covering the leg gathers) is soiled by the excrement.

[0008] Therefore, an object of one aspect of the present disclosure is to provide an absorbent article which can suppress the occurrence of soiling of a wearing article when the absorbent article is used together with a wearing article.

[0009] Solutions for solving problems

[0010] The absorbent article of one aspect of the present disclosure is attached to a reusable cloth underwear worn around the lower body of a wearer and is arranged between the wearing article and the wearer, wherein the absorbent article includes a main body portion, the main body portion being divided into an abdominal portion located on the wearer's abdominal side when the absorbent article and the wearing article are worn together, a dorsal portion located on the wearer's dorsal side when the absorbent article is worn, and a crotch portion located between the abdominal portion and the dorsal portion, the main body portion comprising: a liquid-permeable surface sheet that faces the wearer's skin when worn; and a liquid-impermeable back sheet. It faces the worn article when worn; an absorbent core, which is arranged between the surface sheet and the back sheet, and absorbs the wearer's excrement; and leg gathers, which are arranged along the outer end of the width direction of the main body that is orthogonal to the length direction and the thickness direction, and are contracted at least in the crotch portion along the length direction, and the length direction is the direction in which the ventral portion, the crotch portion and the dorsal portion are arranged. In the thickness direction, the surface sheet and the back sheet overlap, and the leg gathers have a suppression mechanism, which suppresses the force of the crotch leg gathers arranged in the crotch portion being pulled inward in the width direction due to the movement of the wearer's thigh.

[0011] Effects of the Invention

[0012] According to the present disclosure, it is possible to provide an absorbent article which is used together with a wearing article and in which the occurrence of soiling of the wearing article can be suppressed. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] At least the following aspects 1 to 23 are clarified from the description of this specification and the drawings.

[0024] (Method 1)

[0025] An absorbent article is attached to a recyclable cloth underwear worn around the lower body of a wearer and is arranged between the wearer and the wearer, wherein:

[0026] The absorbent article comprises a main body portion, the main body portion being divided into a ventral portion located on the ventral side of the wearer when the absorbent article is worn on the wearer together with the wearing article, a dorsal portion located on the dorsal side of the wearer in the wearing state, and a crotch portion located between the ventral portion and the dorsal portion.

[0027] The main body has:

[0028] a liquid-permeable top sheet facing the skin of the wearer in the wearing state;

[0029] a liquid-impermeable back sheet facing the wearing article in the wearing state;

[0030] an absorbent core disposed between the top sheet and the back sheet and absorbing excrement of the wearer; and

[0031] The leg gathers are arranged along the outer end of the main body in the width direction orthogonal to the length direction and the thickness direction, and are contracted at least in the crotch portion along the length direction, wherein the length direction is the direction in which the ventral portion, the crotch portion, and the dorsal portion are arranged, and in the thickness direction, the surface sheet and the back sheet overlap,

[0032] The leg gathers include a restraining mechanism that restrains a force that pulls the leg gathers disposed in the crotch portion out of the leg gathers inward in the width direction due to movement of the thigh of the wearer.

[0033] In the first embodiment, the leg gathers are provided with a restraining mechanism for restraining the force pulling the crotch gathers inward in the width direction. This can effectively restrain the crotch gathers from being pulled toward the crotch of the wearer as the wearer's thighs move, and can reduce the risk of excrement leaking from the leg gathers. As a result, the occurrence of soiling of the wearing article caused by the leakage can be restrained.

[0034] (Method 2)

[0035] The absorbent article according to aspect 1, wherein

[0036] The suppression mechanism includes a deviation prevention portion that suppresses positional deviation of the leg gather in a shearing direction relative to the wearing article.

[0037] According to the second aspect, when the wearer performs a leg closing action, even if a force (pulling force) is generated to pull the leg gathers including the lower crotch leg gathers toward the crotch of the wearer, the anti-deviating portion can suppress the movement of the leg gathers in the shear direction. As a result, a force (resistance force) can be generated to resist the pulling force and maintain the position of the leg gathers in the width direction. Thus, the lower crotch leg gathers can be effectively prevented from being pulled toward the crotch.

[0038] (Method 3)

[0039] The absorbent article according to aspect 2, wherein:

[0040] The displacement preventing portion is disposed at a position further outward in the width direction than the absorbent core in at least one of the abdominal portion and the dorsal portion.

[0041] When the wearer performs a leg closing action, the above-mentioned pulling force is usually easily generated in the portion of the leg gathers from the end of the body in the width direction to the absorbent core (i.e., the portion that is easily deformed compared to the relatively thick and rigid portion where the absorbent core is arranged). According to mode 3, by providing an anti-deviating portion in such a portion (i.e., the portion outside the absorbent core), the above-mentioned counterforce can be well generated in this portion. As a result, it is possible to effectively prevent the lower leg gathers from being pulled into the crotch portion.

[0042] (Method 4)

[0043] The absorbent article according to aspect 2 or aspect 3, wherein:

[0044] The anti-drifting portion is arranged at a position closer to the outside in the width direction than an imaginary line, which passes through the center between the outer end of the main body in the width direction and the outer end of the absorbent core in the width direction and is parallel to the longitudinal direction.

[0045] (Method 5)

[0046] The absorbent article according to any one of aspects 2 to 4, wherein:

[0047] The main body has leg gathers extending from the ventral part to the dorsal part along the length direction, both ends of the leg gathers in the length direction are fixed at the ventral part and the dorsal part, and the leg gathers are configured to be able to stand up by contracting in the length direction.

[0048] The leg side gathers have a standing support extending in the longitudinal direction at a position inside the outer end of the leg gathers in the width direction.

[0049] The anti-displacement portion is disposed at a position on the outside of the standing support point in the width direction at at least one of the ventral portion and the dorsal portion.

[0050] According to the fourth or fifth aspect, by arranging the anti-deviating portion at a position more than a certain degree outside the leg gather (that is, outside the imaginary line or the standing fulcrum), it is possible to generate a resisting force against the above-mentioned pulling force.

[0051] (Method 6)

[0052] The absorbent article according to any one of aspects 2 to 5, wherein:

[0053] The anti-deviated portion is disposed only on one of the ventral portion and the dorsal portion.

[0054] The leg gathers shrink in the length direction at least in the crotch portion. In addition, there is a case where the leg opening portion of the wearing article to which the absorbent article is mounted is also constructed to shrink to a certain extent in the length direction to improve the wearing feeling (fitting feeling). Therefore, assuming that the anti-drifting portion is arranged in both the ventral portion and the dorsal portion, in order to install the anti-drifting portion of the ventral portion and the dorsal portion at the appropriate position of the wearing article, it is necessary to fully stretch both the leg gathers and the wearing article while accurately aligning the positions, so the burden on the installer is relatively large. In addition, in the case where the leg gathers are fixed to the wearing article at both the ventral portion and the dorsal portion, there is a concern that the anti-drifting portion at only one of the leg gathers and the wearing article will detach from the wearing article due to the difference in the degree of expansion and contraction in the length direction of the leg gathers and the wearing article. In this case, there is a concern that the one of the deflection portions will be fixed to the wearing article again at an inappropriate position. As a result, there is a concern that, for example, the leg gathers are not closely fitted to the wearer's thighs, a gap is formed between the leg gathers and the wearer's thighs, and side leakage from the leg gathers may occur. In contrast, according to the sixth aspect, by arranging the anti-drifting portion only at one of the ventral portion and the dorsal portion of the leg gathers, the occurrence of the above-mentioned problem can be avoided.

[0055] (Method 7)

[0056] The absorbent article according to any one of aspects 2 to 6, wherein:

[0057] A contraction member is disposed at least at the leg gather portion including the crotch leg gather, and the contraction member is arranged along the length direction to contract at least the crotch leg gather along the length direction.

[0058] The anti-deviating portion is disposed on the outside of the shrinking member in the longitudinal direction.

[0059] According to the seventh aspect, by arranging the anti-deviating portion at the part of the leg gather as far outward as possible (i.e., outward in the length direction relative to the contraction member), the above-mentioned counterforce can be generated well. In addition, by arranging the anti-deviating portion so as not to overlap with the contraction member, it is possible to prevent the anti-deviating portion from contracting together with the contraction member, thereby preventing the anti-deviating portions from adhering to each other (for example, when the anti-deviating portion is an adhesive member, the adhesive surfaces are attached to each other). Thus, the convenience of the wearer when attaching the absorbent article to the wearing article can be improved.

[0060] (Method 8)

[0061] The absorbent article according to any one of aspects 2 to 7, wherein:

[0062] A contraction member is disposed at least at the leg gather portion including the crotch leg gather, and the contraction member is arranged along the length direction to contract at least the crotch leg gather along the length direction.

[0063] At least a portion of the displacement prevention portion is arranged to overlap with the shrinking member in the thickness direction when viewed from the longitudinal direction.

[0064] (Method 9)

[0065] The absorbent article according to aspect 8, wherein

[0066] A half or more of the displacement preventing portion in the width direction is arranged to overlap with the shrinking member in the thickness direction when viewed from the longitudinal direction.

[0067] (Method 10)

[0068] The absorbent article according to aspect 8 or aspect 9, wherein:

[0069] The entirety of the displacement preventing portion in the width direction is arranged so as to overlap with the shrinking member in the thickness direction when viewed from the longitudinal direction.

[0070] There is a case where the anti-drifting portion for suppressing positional displacement in the shear direction has a relatively strong resistance to the force in the in-plane direction of the contact surface between the anti-drifting portion and the wearing article (i.e., the force that causes the anti-drifting portion to be displaced relative to the wearing article along a plane parallel to the length direction and the width direction), but has a relatively weak resistance to the force in the out-of-plane direction of the above-mentioned contact surface (i.e., the force that causes the anti-drifting portion to be peeled off from the wearing article). According to any one of the eighth to tenth aspects, by arranging the anti-drifting portion at a position where the contraction force in the length direction of the contraction member is easily acted, the anti-drifting portion is more likely to generate the in-plane force than the out-of-plane force. As a result, the occurrence of a situation where the anti-drifting portion is accidentally detached from the wearing article can be suppressed.

[0071] (Method 11)

[0072] The absorbent article according to any one of aspects 1 to 10, wherein:

[0073] The restraining mechanism has a recessed portion provided at an outer end portion of the leg gather in the width direction and formed so as to be recessed inward in the width direction when viewed from the thickness direction.

[0074] The narrowest portion of the recessed portion, which is located most innerward in the width direction, is disposed in the crotch gather.

[0075] According to aspect 11, by at least one of the following first to third effects, it is possible to effectively suppress the leg gathers from being pulled into the crotch portion.

[0076] (1st effect)

[0077] The pulling force that pulls the leg gather toward the crotch of the wearer during the leg closing action is initially generated at the position farthest from the crotch (i.e., the outer end of the leg gather in the width direction). According to mode 11, since the outer end of the leg gather can be brought closer to the crotch of the wearer by an amount corresponding to the concave portion, the moment when the pulling force first acts on the leg gather (the outer end in the width direction) during the leg closing action can be delayed. As a result, the total pulling force acting on the leg gather during the leg closing action can be reduced.

[0078] (Second effect)

[0079] Since the leg closing action is a rotation action with the crotch as the center (fulcrum), it is considered that a greater pulling force (torque) is generated at a location farther from the crotch. According to method 11, since the outer end of the lower crotch leg gather can be brought closer to the crotch of the wearer by an amount corresponding to the concave portion, the magnitude (maximum value) of the pulling force initially acting on the lower crotch leg gather can be reduced. Thus, in particular, in the initial stage of the leg closing action where a large pulling force is generated, the lower crotch leg gather can be suppressed from entering the crotch side.

[0080] (Third effect)

[0081] It is considered that the above-mentioned pulling force is mainly generated at each point of the outer end of the crotch leg gather along the normal direction of the outer end. Therefore, in the case where no recess is provided, a pulling force in the direction inward in the width direction is generated in the entire area in the length direction of the outer end of the crotch leg gather. On the other hand, in the case where a recess is provided as in method 11, the direction of the pulling force generated at each point of the outer end of the crotch leg gather can be dispersed in multiple directions. As a result, compared with the case where no recess is provided, the component of the pulling force acting on the entire crotch leg gather in the direction inward in the width direction can be reduced.

[0082] (Method 12)

[0083] The absorbent article according to aspect 11, wherein

[0084] The main body has leg gathers extending from the ventral part to the dorsal part along the length direction, both ends of the leg gathers in the length direction are fixed at the ventral part and the dorsal part, and the leg gathers are configured to be able to stand up by contracting in the length direction.

[0085] The leg side gathers have a standing support extending in the longitudinal direction at a position inside the outer end of the leg gathers in the width direction.

[0086] The narrowest portion of the recess is located at a position closer to the inside in the width direction than an imaginary center line, which passes through the center in the width direction between the portion of the outer end portion of the leg pleat that is located closest to the outside in the width direction and the upright support point, and is parallel to the length direction.

[0087] According to aspect 12, by forming the recessed portion relatively large, the outer end of the leg gather is brought as close to the crotch of the wearer as possible, thereby making it possible to well exert the above-mentioned first to third effects.

[0088] (Method 13)

[0089] The absorbent article according to aspect 11, wherein

[0090] The main body has leg gathers extending from the ventral part to the dorsal part along the length direction, both ends of the leg gathers in the length direction are fixed at the ventral part and the dorsal part, and the leg gathers are configured to be able to stand up by contracting in the length direction.

[0091] The leg side gathers have a standing support extending in the longitudinal direction at a position inside the outer end of the leg gathers in the width direction.

[0092] The narrowest portion of the recess is located at a position closer to the outside in the width direction than an imaginary center line, and the imaginary center line passes through the center in the width direction between the portion of the outer end portion of the leg gather that is located closest to the outside in the width direction and the upright support point, and is parallel to the length direction.

[0093] According to aspect 13, by forming the recessed portion relatively small so that at least the narrowest portion is located outside the imaginary center line, the area of ​​the crotch leg gathers can be ensured, thereby effectively suppressing the occurrence of side leakage of excrement from the leg gathers.

[0094] (Method 14)

[0095] The absorbent article according to any one of aspects 11 to 13, wherein:

[0096] When viewed from the thickness direction, the outer end portion of the absorbent core in the width direction has a shape corresponding to the shape of the recessed portion.

[0097] According to mode 14, by forming the shape of the outer end of the absorbent core in the width direction and the end of the absorbent article as a whole in the width direction (i.e., the outer end of the leg gather in the width direction) into the same concave shape, the distance in the width direction between the outer end of the crotch leg gather and the outer end of the absorbent core can be made substantially uniform in the length direction. As a result, the leg gather can be well fitted to the thigh of the wearer. As a result, the occurrence of side leakage of excrement from the leg gather can be well suppressed.

[0098] (Method 15)

[0099] The absorbent article according to any one of aspects 1 to 14, wherein:

[0100] A contraction member is disposed at least at the leg gather portion including the crotch leg gather, and the contraction member is arranged along the length direction to contract at least the crotch leg gather along the length direction.

[0101] The restraining mechanism includes a slit portion extending from an outer end portion of the crotch leg gather in the width direction toward an inner side in the width direction and separating the contraction member at least partially.

[0102] According to mode 15, the crotch leg gathers and the contraction member can be separated into a plurality of parts in the length direction by using the slit portion. Thus, when a pulling force is generated on one part to pull it toward the crotch portion, other parts can be prevented from being pulled toward the crotch portion in conjunction with the one part. That is, when a pulling force is generated on any part of the crotch leg gathers, the influence of the pulling force can be limited to the part, and the pulling force can be prevented from being transmitted to other adjacent parts. As a result, the crotch leg gathers can be effectively prevented from being pulled toward the crotch portion.

[0103] (Method 16)

[0104] The absorbent article according to any one of aspects 1 to 15, wherein:

[0105] The restraining mechanism has a folding start point that is located on the inner side in the width direction than the outer end portion in the width direction of the crotch leg gather and is provided along the longitudinal direction.

[0106] According to the embodiment 16, it can be expected that when a pulling force is applied to the leg gathers, the leg gathers will be folded along the folding starting point before the leg gathers are pulled toward the crotch portion as a whole. As a result of such a folding action, the pulling force applied to the leg gathers can be reduced. Thus, the leg gathers can be effectively prevented from being pulled toward the crotch portion.

[0107] (Method 17)

[0108] The absorbent article according to aspect 16, wherein

[0109] The crotch leg gathers have a low rigidity portion and a high rigidity portion, the high rigidity portion having a higher rigidity than the low rigidity portion,

[0110] The folding starting point is formed by a boundary between the low rigidity portion and the high rigidity portion.

[0111] According to aspect 17, the folding start point can be easily and reliably formed by utilizing the boundary between the low rigidity portion and the high rigidity portion.

[0112] (Method 18)

[0113] The absorbent article according to aspect 16, wherein

[0114] The folding starting point is formed by an embossed portion provided on the crotch leg gather so as to extend along the longitudinal direction.

[0115] According to aspect 18, the folding starting point can be easily and reliably formed using the embossed portion.

[0116] (Method 19)

[0117] The absorbent article according to any one of aspects 1 to 18, wherein:

[0118] A contraction member is disposed at least at the leg gather portion including the crotch leg gather, and the contraction member is arranged along the length direction to contract at least the crotch leg gather along the length direction.

[0119] The shrinking member functions as at least a part of the suppressing mechanism by being configured as an integral sheet-shaped member having a width greater than or equal to a certain width in the width direction.

[0120] According to mode 19, the rigidity of the leg gathers can be ensured by using the contraction member formed as an integral sheet-like member. In addition, even if the leg gathers are pulled inward toward the crotch portion by the pulling force and the contraction member is temporarily contracted in the width direction, when the pulling force is weakened later (for example, when the wearer opens the legs again after closing the legs, etc.), a restoring force is generated in the contraction member to restore the original sheet-like shape. Thus, it is possible to suppress the situation in which the leg gathers are gradually pulled inward toward the crotch portion due to repeated leg closing actions (i.e., cumulative pulling).

[0121] (Method 20)

[0122] An absorbent article according to aspect 19, wherein

[0123] The restraining mechanism has a folding starting point, which is located at a position closer to the inside in the width direction than the outer end of the crotch leg gather in the width direction and is arranged along the length direction.

[0124] The folding start point is provided at least one of a position on the inner side of the contraction member in the width direction and a position on the outer side of the contraction member in the width direction.

[0125] According to method 20, the effect of method 19 can be obtained, and the same effect as method 16 can be obtained.

[0126] (Method 21)

[0127] An absorbent article according to aspect 20, wherein

[0128] The leg gathers have:

[0129] a high rigidity portion provided with the contraction member; and

[0130] a low rigidity portion provided at least one of a position closer to the inside in the width direction than the shrinking member and a position closer to the outside in the width direction than the shrinking member, and having a rigidity lower than that of the high rigidity portion,

[0131] The folding starting point is formed by the boundary between the high rigidity portion and the low rigidity portion.

[0132] The shrinking member is not arranged in the low rigidity portion.

[0133] According to aspect 21, the folding starting point can be easily and reliably formed by utilizing the boundary between the low rigidity portion and the high rigidity portion.

[0134] (Method 22)

[0135] The absorbent article according to any one of aspects 19 to 21, wherein:

[0136] The restraining mechanism includes a slit portion extending from an outer end portion of the crotch leg gather in the width direction toward an inner side in the width direction and separating the contraction member at least partially.

[0137] When the crotch gathers are separated into a plurality of parts by the slits, a certain degree of rigidity is required for each part in order to maintain the stability of each part. According to the embodiment 22, since the part of the shrinking member having a relatively high rigidity formed in a sheet shape is arranged in each part separated by the slits, the rigidity of each part can be ensured. Therefore, the same effect as that of the embodiment 15 can be obtained by providing the slits while ensuring the stability of each part separated by the slits.

[0138] (Method 23)

[0139] The absorbent article according to any one of aspects 19 to 22, wherein:

[0140] The restraining mechanism has a recessed portion provided at an outer end portion of the leg gather in the width direction and formed so as to be recessed inward in the width direction when viewed from the thickness direction.

[0141] The narrowest portion of the recessed portion, which is located most innerward in the width direction, is disposed on the outer side of the shrinking member in the width direction in the crotch gather.

[0142] In the case where the area of ​​the leg gathers (particularly the crotch leg gathers) is reduced due to the recessed portion, a certain degree of rigidity is required for the crotch leg gathers in order to maintain the stability of the crotch leg gathers. According to the method 23, since the shrinking member with relatively high rigidity formed in a sheet shape is arranged on the crotch leg gathers, the rigidity of the crotch leg gathers can be ensured. Therefore, the same effect as that of the method 11 can be obtained by providing the recessed portion while ensuring the stability of the crotch leg gathers.

[0143] [Implementation Method]

[0144] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In the following description, the same reference numerals are used for the same or corresponding elements, and repeated descriptions are omitted.

[0145] [First embodiment]

[0146] Reference Figure 1 to Figure 4 The structure of the absorbent article 1 according to the first embodiment will be described. Figure 1 This is a plan view of the absorbent article 1 as viewed from the skin side. Figure 2 This is a plan view of the absorbent article 1 as viewed from the non-skin side. Figure 1 and Figure 2 This shows a state in which the absorbent article 1 is stretched to a state where wrinkles are not formed (hereinafter referred to as “stretched state”). Figure 3 The absorbent article 1 is schematically shown along Figure 1 The cross-sectional structure of line III-III is shown in FIG. Figure 4 The absorbent article 1 is schematically shown along Figure 1 Diagram of the cross-sectional structure of line IV-IV.

[0147] In the present embodiment, the "wearer" is a person wearing the wearing article 2 with the absorbent article 1 attached thereto. The "skin side" is the side facing the wearer's skin when the absorbent article 1 and the wearing article 2 are worn on the wearer together (hereinafter referred to as the "wearing state"). The "non-skin side" is the side facing the opposite side to the wearer's skin in the wearing state.

[0148] Next, the stretched state of the absorbent article 1 (see Figure 1 and Figure 2 ) is represented as the “length direction L”, the short side direction of the absorbent article 1 perpendicular to the length direction L is represented as the “width direction W”, and the direction perpendicular to the length direction L and the width direction W is represented as the “thickness direction T” (refer to Figure 3 and Figure 4 ). The length direction L is the direction extending from the front side (ventral side) of the wearer's body to the back side (dorsal side) of the body when worn. The width direction W is the direction consistent with the left-right direction of the wearer when worn. The thickness direction T is the direction in which the raw materials constituting the absorbent article 1 (the surface sheet 11, the back sheet 12, the absorbent body 13, etc. described later) are stacked.

[0149] The absorbent article 1 is a wearing article 2 (see Figure 5 to Figure 7 ) is an absorbent article used simultaneously with a wearer. The absorbent article 1 is, for example, a disposable diaper. The absorbent article 1 is attached to a wearing article 2 and is disposed between the wearing article 2 and the wearer. The wearing article 2 is a reusable cloth underwear.

[0150] The absorbent article 1 has a main body 10. Figure 1 and Figure 2 As shown, the main body 10 has a rectangular shape when viewed from the thickness direction T in the stretched state. The main body 10 is divided into a ventral part 101 located on the ventral side of the wearer in the worn state, a dorsal part 102 located on the dorsal side of the wearer in the worn state, and a crotch part 103 located between the ventral part 101 and the dorsal part 102. The ventral part 101, the crotch part 103 and the dorsal part 102 are arranged along the length direction L from the ventral side (front) of the wearer toward the dorsal side (back). As an example, when the main body 10 is divided into four equal parts in the length direction L, a region located at the most ventral position corresponds to the ventral part 101, a region located at the most dorsal position corresponds to the dorsal part 102, and two regions located between the ventral part 101 and the dorsal part 102 (i.e., the central part in the length direction of the main body 10) correspond to the crotch part 103.

[0151] The main body 10 includes a top sheet 11, a back sheet 12, an absorber 13, and a pair of side sheets 14. The top sheet 11, the back sheet 12, the absorber 13, and the pair of side sheets can be bonded to each other using a known material such as an adhesive.

[0152] The top sheet 11 is a liquid-permeable sheet disposed on the skin side of the wearer and facing the skin of the wearer when worn. The top sheet 11 can be formed of, for example, a liquid-permeable nonwoven fabric or woven fabric, a synthetic resin film having liquid-permeable holes, or a composite sheet thereof.

[0153] The back sheet 12 is a liquid-impermeable sheet material disposed on the non-skin side of the wearer and facing the wearing article 2 when worn. The back sheet 12 can be formed, for example, by a liquid-impermeable nonwoven fabric, a synthetic resin film, or a composite sheet thereof. In the present embodiment, the back sheet 12 has a leakproof sheet 12a and an outer sheet 12b. The leakproof sheet 12a is formed by a liquid-impermeable synthetic resin film. The outer sheet 12b is formed by a liquid-impermeable nonwoven fabric and is disposed at a position closer to the outside than the leakproof sheet 12a.

[0154] The absorbent body 13 is arranged between the surface sheet 11 and the leakproof sheet 12a (back sheet 12). The absorbent body 13 includes an absorbent core 13a and a core wrap 13b covering the absorbent core 13a. The absorbent core 13a is a member for absorbing the excrement of the wearer, and has liquid absorbency and liquid retention. The absorbent core 13a is, for example, a laminate of an absorbent material containing pulverized pulp or a superabsorbent polymer (SAP), or a mixture thereof. The core wrap 13b is, for example, tissue paper or a nonwoven fabric sheet.

[0155] The pair of side sheets 14 are arranged outside the center of the absorber 13 in the width direction W so as to cover both sides of the top sheet 11 in the width direction W over the entire area in the length direction L. The side sheets 14 are liquid-impermeable sheets and can be made of, for example, hydrophobic nonwoven fabric.

[0156] like Figure 1 As shown, in this embodiment, as an example, when viewed from the thickness direction T, the absorbent core 13a is formed into a gourd shape (or an hourglass shape), and has a shape in which the central portion in the longitudinal direction L of the absorbent core 13a is narrowed. That is, the width (length in the width direction W) of the absorbent core 13a is the largest at the portion including the two ends of the ventral side and the two ends of the dorsal side, and is the smallest at the portion including the approximately central portion in the longitudinal direction L of the absorbent core 13a (the portion located in the crotch portion 103). In addition, as Figure 3 and Figure 4As shown, as an example, the core wrap 13b has a constant width greater than the maximum width of the absorbent core 13a in the entire region along the longitudinal direction L. For example, when viewed from the thickness direction T, the core wrap 13b is formed in a rectangular shape including the absorbent core 13a.

[0157] The main body portion 10 has a pair of leg gathers 15 and a pair of leg side gathers 16. In the width direction W, the pair of leg side gathers 16 are located on the inner side of the pair of leg side gathers 16.

[0158] The leg gathers 15 are provided along the outer end 10a in the width direction W of the main body 10. The leg gathers 15 are configured to be contracted in the length direction L at least at the crotch portion 103. The leg gathers 15 are provided outside the leg gathers 16 with the standing fulcrum 16b of the leg gathers 16 sandwiched therebetween, and extend in the length direction L from the ventral portion 101 to the dorsal portion 102. Figure 3 and Figure 4 As shown, the standing fulcrum 16b is formed by the bonding portion of the side sheet 14 and the surface sheet 11 bonded together for the leg gathers 15 and the leg side gathers 16. In this embodiment, the entire area of ​​the leg gathers 15 in the longitudinal direction L of the main body 10 is formed by the portion between the outer end 10a and the standing fulcrum 16b.

[0159] A contraction member 152 is arranged in a portion of the leg gathers 15 that includes at least the crotch leg gathers 151 arranged in the crotch portion 103. The contraction member 152 extends along the length direction L and contracts at least the crotch leg gathers 151 along the length direction L. The contraction member 152 has a width greater than a certain width in the width direction W. In addition, the contraction member 152 is configured as an integrated sheet-like member. For example, the contraction member 152 can be formed by a non-woven fabric (stretchable non-woven fabric) having stretchability in the length direction L. Alternatively, the contraction member 152 can also be formed by a plurality of elastic members (such as elastic bands) that are arranged separately from each other in the width direction W and extend respectively in the length direction L, and a sheet member that covers the plurality of elastic members in a bag-like manner.

[0160] The pair of leg gathers 16 extend along the length direction L from the ventral part 101 to the dorsal part 102. Both ends of the leg gathers 16 in the length direction L are fixed at the ventral part 101 and the dorsal part 102. More specifically, a fixing area B ( 20 ) where the leg gathers 16 and the top sheet 11 are fixed to each other is provided at both ends of the leg gathers 16 in the length direction L. Figure 1 The leg-side gathers 16 and the surface sheet 11 are fixed (bonded) to each other in the fixing region B, for example, by bonding with an adhesive or the like, ultrasonic bonding, or heat fusion bonding with an embossing roller.

[0161] The standing fulcrum 16b of the leg gathers 16 is located in the extended state at a position that is more inward in the width direction W than the outer end 10a in the width direction W of the main body 10. The standing fulcrum 16b extends along the length direction L from the ventral part 101 to the dorsal part 102. In the present embodiment, the standing fulcrum 16b is located in the inner side of the contraction member 152 of the leg gathers 15 in the width direction W. However, the positional relationship between the standing fulcrum 16b and the contraction member 152 is not limited to the above relationship. For example, when viewed from the thickness direction T, the standing fulcrum 16b may partially overlap with the contraction member 152. In addition, in Figure 1 In the extended state shown, the pair of leg gathers 16 are folded inward in the width direction W. Therefore, the tops 16a of the pair of leg gathers 16 are located inward in the width direction W relative to the standing fulcrums 16b.

[0162] The leg side gathers 16 are configured to be able to stand up by contracting along the length direction L. More specifically, the leg side gathers 16 have an elastic member 17 extending along the length direction L between a pair of fixed areas B at both end portions provided in the length direction L. As an example, the elastic member 17 is composed of one or more (three in the present embodiment) elastic threads. The leg side gathers 16 can stand up by contracting the elastic member 17 along the length direction L. In the worn state, the elastic member 17 contracts and the leg side gathers 16 are in an upright state, thereby suppressing the leakage of excrement to the outside of the main body 10 (side leakage). That is, by the leg side gathers 16 being in an upright state, a leak-proof cuff is formed in the lower crotch portion 103 to prevent excrement from leaking to the outside along the surface of the surface sheet 11.

[0163] like Figure 3 and Figure 4 As shown, in this embodiment, the leg gathers 15 are mainly composed of the back sheet 12 and the side sheet 14, which are closer to the outside of the standing fulcrum 16b in the width direction W, and the contraction member 152. In addition, the leg side gathers 16 are mainly composed of the side sheet 14, which are closer to the inside of the standing fulcrum 16b in the width direction W, and the elastic member 17.

[0164] like Figure 4As shown, the portion of the leg gather 15 (crotch leg gather 151) that is closer to the outside than the outer end 152a in the width direction W of the contraction member 152 is a relatively thin portion composed of the back sheet 12 and the side sheet 14, and constitutes a low-rigidity portion 151A with relatively low rigidity. On the other hand, for the portion of the leg gather 15 (crotch leg gather 151) where the contraction member 152 is arranged, in addition to the back sheet 12 and the side sheet 14, the contraction member 152 is also provided, so that this portion is thicker than the low-rigidity portion 151A, and constitutes a high-rigidity portion 151B with higher rigidity than the low-rigidity portion 151A. By utilizing such a difference in rigidity, the crotch leg gather 151 is easily folded along the folding starting point (in this embodiment, the portion along the outer end 152a), and the folding starting point is along the boundary BL1 between the low-rigidity portion 151A and the high-rigidity portion 151B.

[0165] Similarly, the portion of the leg gather 15 (crotch leg gather 151) that is closer to the inside than the inner end 152b in the width direction W of the contraction member 152 is a relatively thin portion composed of the back sheet 12 and the side sheet 14, and constitutes a low-rigidity portion 151C with relatively low rigidity. The crotch leg gather 151 is made easy to fold along the folding starting point (in this embodiment, the portion along the inner end 152b), and the folding starting point is along the boundary BL2 between the low-rigidity portion 151C and the high-rigidity portion 151B. As described above, in this embodiment, the folding starting point is formed on both the outer side and the inner side of the contraction member 152 by the outer side end 152a and the inner side end 152b of the contraction member 152.

[0166] The outer sheet 12b (back sheet 12) is provided with a connecting portion 50 configured to be connected to the wearing article 2. In addition, "connection" refers to the situation where it is fixed to the wearing article 2 to a degree that it can be detached, including various means such as snapping and bonding. The connecting portion 50 can be composed of, for example, a snap hook (for example, a region including a plurality of pins (hook structure) having claws at the top end), an adhesive sheet, etc. In the present embodiment, the connecting portion 50 is composed of an adhesive sheet and includes two connecting portions 51 and 52. The connecting portion 51 is formed in a rectangular region approximately in the center of the back side portion 102, the length in the width direction W being longer than the length in the length direction L. The connecting portion 52 is provided in a region on the side of the backrest side portion 102 in the crotch portion 103. The connecting portion 52 is formed in a rectangular region, the length in the length direction L being slightly longer than the length in the width direction W.

[0167] In addition, an anti-drift portion 60 is provided in the portion of each leg gather 15 constituting a pair of leg gathers 15 in the outer sheet 12b (back sheet 12). The anti-drift portion 60 suppresses positional deviation of the absorbent article 1 relative to the wearing article 2 in the shearing direction. The anti-drift portion 60 can be formed, for example, of the same material as the above-mentioned bonding portion 50. The shearing direction refers to a direction parallel to the contact surface between the absorbent article 1 and the wearing article 2 (in-plane direction), and refers to a direction perpendicular to the thickness direction T (i.e., a direction along a surface parallel to the length direction L and the width direction W). In the present embodiment, the anti-drift portion 60 includes two anti-drift portions 61 and 62 formed in a rectangular shape of approximately the same size (a rectangular shape whose length in the length direction L is longer than that in the width direction W). The anti-drift portions 61 and 62 are arranged in a row along the width direction W, and the anti-drift portion 61 is located at a position closer to the outside of the anti-drift portion 62 in the width direction W.

[0168] In the present embodiment, when viewed from the width direction W, at least a portion of the coupling portion 50 (in the present embodiment, the coupling portion 51) is configured to overlap with the anti-deviation portion 60. In other words, the range where at least a portion of the coupling portion 50 (the coupling portion 51) is formed in the longitudinal direction L overlaps with the range where the anti-deviation portion 60 is formed in the longitudinal direction L. In addition, the coupling portion 50 overlaps with the absorbent core 13a in the thickness direction T. According to the above structure, the following effects can be achieved. First, the anti-deviation portion 60 is provided at a position on the outside in the width direction W of the region where the absorbent article 1 is fixed to the wearing article 2 by the coupling portion 51. Thus, when the absorbent article 1 is mounted on the wearing article 2, the absorbent article 1 can be stably fixed to the wearing article 2 at the rigid portion (i.e., the coupling portion 51) where the absorbent body 13 is provided. That is, within the range where the anti-deviation portion 60 is provided in the longitudinal direction L, the absorbent article 1 is firmly fixed to the wearing article 2 by the coupling portion 51. After that, by expanding the leg gathers 15 in the width direction W, the anti-deviation portion 60 can be fully expanded in the width direction W. That is, the contact area between the anti-deviation portion 60 and the wearing article 2 can be fully ensured. As a result, the positional deviation suppression effect of the anti-deviation portion 60 can be improved. In addition, when the lower crotch leg gathers 151 are pulled toward the crotch side of the wearer as the wearer's thigh moves, the force in the shearing direction acting on the anti-deviation portion 60 can be well dispersed to the joint 51 provided in the same range as the anti-deviation portion 60 in the length direction L. As a result, the fixing force of the anti-deviation portion 60 relative to the force in the shearing direction can be enhanced, and the force pulling the lower crotch leg gathers 151 inward in the width direction W can be effectively suppressed.

[0169] Next, refer to Figure 5 to Figure 7 The wearing article 2 to which the absorbent article 1 is attached will be described. Figure 5 This is a plan view of the wearing article 2 as viewed from the skin side. Figure 6 It is a top view of the wearing article 2 to which the absorbent article 1 is attached. Figure 7 This is a front view showing the absorbent article 1 and the wearing article 2 in the worn state.

[0170] The wearing article 2 has an inner surface 2a facing the back surface (exterior sheet 12b) of the absorbent article 1 when worn, and an outer surface 2b on the opposite side of the inner surface 2a (see Figure 7 ). The wearing article 2 is divided into an abdominal portion 201 located on the abdominal side of the wearer when worn, a dorsal portion 202 located on the dorsal side of the wearer when worn, and a crotch portion 203 located between the abdominal portion 201 and the dorsal portion 202. The abdominal portion 201, the crotch portion 203, and the dorsal portion 202 are arranged along the length direction L from the abdominal side to the dorsal side of the wearer. As an example, when the wearing article 2 is divided into four equal parts in the length direction L, a region located at the most abdominal position corresponds to the abdominal portion 201, a region located at the most dorsal position corresponds to the dorsal portion 202, and two regions located between the abdominal portion 201 and the dorsal portion 202 correspond to the crotch portion 203.

[0171] like Figure 6 As shown, in this embodiment, the absorbent article 1 is attached to the substantially central portion in the length direction L and the width direction W of the wearing article 2. For example, the absorbent article 1 is arranged on the wearing article 2 in such a manner that the end portion in the length direction L of the absorbent article 1 substantially coincides with the end portion in the length direction L of the wearing article 2, and the center in the width direction W of the absorbent article 1 substantially coincides with the center in the width direction W of the wearing article 2. In addition, the absorbent article 1 is arranged on the wearing article 2 in such a manner that the outer sheet 12b faces the inner surface 2a. Thus, the absorbent article 1 is attached to the wearing article 2. That is, the coupling portion 50 and the anti-drift portion 60 provided on the outer sheet 12b are fixed to the inner surface 2a of the wearing article 2.

[0172] The inner surface 2a of the dorsal portion 202 is provided with fixing portions 2c at both ends in the width direction W. The fixing portions 2c are composed of, for example, a hook portion of a nylon hook and loop fastener (one of a convex portion and a concave portion), etc. In addition, fixing portions 2d corresponding to the fixing portions 2c are provided at both ends in the width direction W of the outer surface 2b of the ventral portion 201. The fixing portions 2d are composed of, for example, a loop portion of a nylon hook and loop fastener (the other of a convex portion and a concave portion), etc. Figure 7 As shown, in the wearing state, each fixing part 2c is connected with each fixing part 2d. Thus, the side edge part in the width direction W of the crotch part 203 constitutes the leg opening part 2e.

[0173] like Figure 7As shown, the leg opening 2e is an opening formed for the legs (thighs H1) of the wearer H to pass through when the leg opening 2e is worn. An elastic member 2f that contracts along the leg opening 2e is provided along the leg opening 2e. The elastic member 2f is, for example, an elastic cord, a stretch sheet, etc. Figure 7 , the portion indicated as H2 is the abdomen (lower abdomen) of the wearer H.

[0174] like Figure 6 As shown in FIG. 1 , the absorbent article 1 is configured such that, in the state in which the absorbent article 1 is attached to the wearing article 2, at least a portion of the crotch leg gathers 151 protrudes from the wearing article 2 in the width direction W. Figure 7 As shown in FIG. 1 , when the wearer is wearing the article 2, at least a portion of the leg gathers 151 is exposed at a position further outward than the leg opening 2e of the article 2. The leg gathers 15 have a restraining mechanism that restrains the leg gathers 151 (mainly the portion exposed at a position further outward than the leg opening 2e when the wearer is wearing the article 2 as described above) from being pulled inward in the width direction W due to the movement of the thigh H1 of the wearer H. That is, the restraining mechanism serves to restrain the leg gathers 151 from being pulled into the crotch of the wearer H, thereby maintaining the crotch of the article 2 as shown in FIG. Figure 7 As shown, at least a portion of the crotch gathers 151 protrudes outward from the leg opening 2e of the wearing article 2. In this embodiment, at least the displacement prevention portion 60 and the shrinking member 152 function as a suppressing mechanism.

[0175] [Effects of the First Embodiment]

[0176] As described above, in the absorbent article 1, the leg gathers 15 are provided with a suppressing mechanism that suppresses the force that pulls the crotch leg gathers 151 inward in the width direction W. As a result, the crotch leg gathers 151 can be effectively suppressed from being pulled toward the crotch of the wearer H as the thigh H1 of the wearer H moves, and the risk of excrement leaking from the leg gathers 15 can be reduced. As a result, the occurrence of soiling of the wearing article 2 due to the side leakage can be suppressed.

[0177] As described above, the suppression mechanism includes the anti-deviation portion 60, which suppresses the positional deviation of the leg gathers 15 in the shearing direction (the direction along the plane parallel to the length direction L and the width direction W) relative to the wearing article 2. According to the above structure, when the wearer H performs a leg closing action, even if a force (pulling force) is generated to pull the leg gathers 15 including the lower crotch leg gathers 151 toward the crotch side of the wearer H, the anti-deviation portion 60 can suppress the movement of the leg gathers 15 in the shearing direction. As a result, a force (counterforce) to resist the above-mentioned pulling force and maintain the position of the leg gathers 15 in the width direction W can be generated. As a result, the lower crotch leg gathers 151 can be effectively suppressed from being pulled into the crotch.

[0178] like Figure 1 to Figure 3 As shown, the anti-deviation portion 60 is arranged at a position on the outside of the absorbent core 13a in the width direction W at least one of the ventral portion 101 and the dorsal portion 102 (the dorsal portion 102 in the present embodiment). When the wearer H performs the leg closing action, it is usually easy to generate the above-mentioned pulling force on the portion of the leg gathers 15 from the end portion (outer end portion 10a) in the width direction W of the main body 10 to the absorbent core 13a (i.e., the portion that is easily deformed compared to the relatively thick and high rigidity portion where the absorbent core 13a is arranged). According to the above-mentioned structure, by providing the anti-deviation portion 60 in such a portion (i.e., the portion on the outside of the absorbent core 13a), the above-mentioned counterforce can be well generated in this portion. As a result, it is possible to effectively prevent the lower crotch leg gathers 151 from being pulled into the crotch portion.

[0179] like Figure 1 As shown, the anti-drifting portion 60 (in this embodiment, the anti-drifting portion 61 and a part of the anti-drifting portion 62) is arranged at a position on the outside in the width direction W than the imaginary line VL, which passes through the center between the outer end 10a and the outer end of the absorbent core 13a in the width direction W (in this embodiment, the end of the absorbent core 13a located most on the outside in the width direction W) and is parallel to the longitudinal direction L. In addition, the anti-drifting portion 60 is arranged on the outside in the width direction W than the standing support 16b of the leg side gathers 16. According to any of the above-mentioned structures, by arranging at least a part of the anti-drifting portion 60 at a position on the outside to a certain extent (that is, on the outside than the imaginary line VL or the standing support 16b) in the leg gathers 15, it is possible to generate a good resistance force against the above-mentioned pulling force.

[0180] As described above, in the present embodiment, the anti-deviation portion 60 is disposed only in the dorsal portion 102. The leg gathers 15 are contracted in the longitudinal direction L at least in the crotch portion 103. In addition, there is a case where the leg opening portion 2e of the wearing article 2 to which the absorbent article 1 is mounted is also configured to contract to a certain extent in the longitudinal direction L to improve the wearing feeling (fitting feeling). In the present embodiment, the leg opening portion 2e is configured to contract in the longitudinal direction L by the elastic member 2f disposed along the leg opening portion 2e. Therefore, if the anti-deviation portion 60 is disposed in both the ventral portion 101 and the dorsal portion 102, in order to mount the anti-deviation portion 60 of each of the ventral portion 101 and the dorsal portion 102 at the appropriate position of the wearing article 2, it is necessary to fully stretch both the leg gathers 15 and the wearing article 2 while accurately aligning the positions, so the burden on the installer is large. In addition, when the leg gathers 15 are fixed to the wearing article 2 at both the ventral part 101 and the dorsal part 102, there is a concern that the anti-shifting part 60 at only one of the ventral part 101 and the dorsal part 102 may be detached from the wearing article 2 due to the difference in the degree of stretching in the longitudinal direction L between the leg gathers 15 and the wearing article 2 (mainly the leg opening 2e). In this case, there is a concern that the anti-shifting part 60 at the one may be fixed to the wearing article 2 again at an inappropriate position. As a result, for example, there is a concern that the leg gathers 15 and the thigh part H1 of the wearer H are not closely attached to each other, and a gap may be generated between the leg gathers 15 and the thigh part H1 of the wearer H, thereby causing side leakage from the leg gathers 15. In contrast, according to the structure in which the anti-shifting part 60 is arranged at only one of the ventral part 101 and the dorsal part 102 as in the present embodiment, the above-mentioned problem can be avoided.

[0181] In addition, the anti-deviation portion 60 is arranged at a position on the outside of the contraction member 152 in the length direction L. According to the above structure, by arranging the anti-deviation portion 60 at a portion of the leg gather 15 as far out as possible (i.e., a portion on the outside of the contraction member 152 in the length direction L), the above-mentioned counterforce can be well generated. In addition, by arranging the anti-deviation portion 60 so as not to overlap with the contraction member 152, it is possible to prevent the anti-deviation portion 60 from shrinking together with the contraction member 152, thereby preventing the anti-deviation portions 60 from sticking to each other (for example, when the anti-deviation portion 60 is an adhesive member, the adhesive surfaces are attached to each other). As a result, the convenience of the installer when installing the absorbent article 1 on the wearing article 2 can be improved.

[0182] In addition, the entirety of the anti-drifting portion 60 in the width direction W (in this embodiment, the entirety of the anti-drifting portions 61 and 62) is arranged so as to overlap with the contraction member 152 in the thickness direction T when viewed from the length direction L. In some cases, the anti-drifting portion 60 for suppressing positional displacement in the shear direction has a relatively strong resistance to the force in the in-plane direction of the contact surface between the anti-drifting portion 60 and the wearing article 2 (i.e., the force that attempts to displace the anti-drifting portion 60 relative to the wearing article 2 along a plane parallel to the length direction L and the width direction W), and a relatively weak resistance to the force in the out-of-plane direction of the contact surface (i.e., the force that attempts to peel the anti-drifting portion 60 from the wearing article 2). According to the above configuration, by arranging the anti-drifting portion 60 at a position where the contraction force of the contraction member 152 in the length direction L is easily acted, the in-plane force is more likely to be generated in the anti-drifting portion 60 than the out-of-plane force. As a result, the occurrence of a situation where the anti-drifting portion 60 is accidentally separated from the wearing article 2 can be suppressed.

[0183] Furthermore, it is also possible that more than half of the anti-deviation portion 60 in the width direction W is configured to overlap with the shrink member 152 in the thickness direction T when viewed from the length direction L, rather than the entire anti-deviation portion 60 in the width direction W being configured in this way. Even in this case, although it is considered that the effect is slightly inferior compared to the case where the entire anti-deviation portion 60 in the width direction W overlaps with the shrink member 152, the same effect as the above-mentioned effect can be obtained. Furthermore, it is also possible that at least a portion of the anti-deviation portion 60 is configured to overlap with the shrink member 152 in the thickness direction T when viewed from the length direction L. Even in this case, although it is considered that the effect is slightly inferior compared to the case where more than half of the anti-deviation portion 60 in the width direction W overlaps with the shrink member 152, the same effect as the above-mentioned effect can be obtained.

[0184] In addition, the contraction member 152 is configured as an integrated sheet-like member having a width greater than a certain width in the width direction W as described above, so that it functions as at least part of the suppression mechanism. According to the above structure, the rigidity of the leg gathers 151 can be ensured by using the contraction member 152 configured as an integrated sheet-like member. In addition, even if the leg gathers 151 are pulled in toward the crotch side by the pulling force and the contraction member 152 is temporarily contracted in the width direction W, when the pulling force is weakened later (for example, when the wearer H opens the legs (thigh H1) again after performing the leg closing action), a restoring force is generated in the contraction member 152 to restore to the original sheet-like shape. As a result, it is possible to suppress the situation in which the leg gathers 151 are gradually pulled in toward the crotch side (i.e., accumulated pulling) due to repeated leg closing actions.

[0185] In addition, the restraining mechanism has a folding starting point, which is located at a position that is closer to the inside in the width direction W than the outer end 10a in the width direction W of the crotch leg gather 151, and is provided along the outer end 10a of the crotch leg gather 151. That is, such a folding starting point functions as at least part of the restraining mechanism. In the present embodiment, the folding starting point is provided at two positions, a position that is closer to the inside in the width direction W than the contraction member 152 and a position that is closer to the outside in the width direction W than the contraction member 152. In addition, as Figure 4 As shown, in this embodiment, the folding starting point is composed of the boundary BL1 between the low rigidity portion 151A and the high rigidity portion 151B (i.e., the outer end portion 152a of the contraction member 152), and the boundary BL2 between the low rigidity portion 151C and the high rigidity portion 151B (i.e., the inner end portion 152b of the contraction member 152).

[0186] According to the above structure, it can be expected that when a pulling force is generated on the lower leg gathers 151, the lower leg gathers 151 will be folded along the folding starting point before the lower leg gathers 151 are pulled toward the crotch portion as a whole. As a result of such a folding action, the pulling force acting on the lower leg gathers 151 can be weakened. Thus, the situation where the lower leg gathers 151 are pulled toward the crotch portion can be effectively suppressed. In addition, according to the above structure, the folding starting point can be easily and reliably formed by utilizing the boundary between the low rigidity portions 151A, 151C and the high rigidity portion 151B. In the present embodiment, it can be expected that by generating a folding action between the low rigidity portion 151A and the high rigidity portion 151B, the transmission of the pulling force from the low rigidity portion 151A that initially generates the pulling force to the high rigidity portion 151B can be suppressed. Likewise, it can be expected that the transmission of the pulling force from the high rigidity portion 151B to the low rigidity portion 151C is suppressed by causing the folding action between the high rigidity portion 151B and the low rigidity portion 151C.

[0187] In addition, the folding starting point formed in the crotch leg gathers 151 and extending in the length direction L as described above may also be formed by an embossed portion provided in the crotch leg gathers 151 in a manner extending in the length direction L. The embossed portion refers to a portion formed with embossing by embossing processing. According to such a structure, the folding starting point can be easily and reliably formed using the embossed portion.

[0188] [Second embodiment]

[0189] Reference Figure 8 The structure of the absorbent article 1A according to the second embodiment will be described. Figure 8 This is a plan view of the absorbent article 1A as viewed from the skin side.

[0190] The absorbent article 1A is different from the absorbent article 1 in that it is configured as follows, and the other structures are the same as those of the absorbent article 1. The absorbent article 1A has a main body 10A instead of the main body 10. The main body 10A is different from the main body 10 in that the main body 10A has a recess 10b provided at the outer end 10a of the leg gather 15. The recess 10b is formed so that the portion including at least the lower crotch leg gather 151 is in the thickness direction T (refer to Figure 3 and Figure 4 ) is recessed inward in the width direction W when viewed from the side. The narrowest portion 10c of the recess 10b, which is located most inward in the width direction W, is disposed at the crotch leg gather 151. For example, the narrowest portion 10c is disposed at the approximate center portion in the length direction L of the main body portion 10A (the approximate center position in the length direction L of the crotch portion 103).

[0191] According to the absorbent article 1A provided with such recessed portions 10 b , it is possible to effectively suppress the leg gathers 151 from being pulled into the crotch portion by at least one of the following first to third effects.

[0192] (1st effect)

[0193] The pulling force that pulls the leg gathers 151 toward the crotch of the wearer H during the leg closing action of the wearer H is initially generated at the position farthest from the crotch (i.e., the outer end 10a of the leg gathers 151 in the width direction W). According to the absorbent article 1A, since the outer end 10a of the leg gathers 151 can be brought closer to the crotch of the wearer H by an amount corresponding to the recess 10b, the moment when the pulling force first acts on the leg gathers 151 (the outer end 10a in the width direction W) during the leg closing action can be delayed. As a result, the total pulling force acting on the leg gathers 151 during the leg closing action can be reduced.

[0194] (Second effect)

[0195] Since the leg closing action is a rotation action with the crotch as the center (fulcrum), it is considered that a greater pulling force (torque) is generated at a location farther from the crotch. According to the absorbent article 1A, since the outer end 10a of the lower crotch leg gathers 151 can be brought closer to the crotch of the wearer H by an amount corresponding to the concave portion 10b, the magnitude (maximum value) of the pulling force initially acting on the lower crotch leg gathers 151 can be reduced. As a result, particularly in the initial stage of the leg closing action in which a large pulling force is generated, the lower crotch leg gathers 151 can be prevented from entering the crotch side.

[0196] (Third effect)

[0197] It is considered that the above-mentioned pulling force is mainly generated at each point (each position along the length direction L) of the outer end 10a of the crotch leg gather 151 along the normal direction of the outer end 10a. Therefore, in the case where the recess 10b is not provided, a pulling force in the direction toward the inner side in the width direction W is generated in the entire area in the length direction L of the outer end 10a of the crotch leg gather 151. On the other hand, in the case where the recess 10b is provided as in the absorbent article 1A, the direction of the pulling force generated at each point of the outer end 10a of the crotch leg gather 151 can be dispersed in multiple directions (i.e., directions inclined relative to the width direction W). As a result, compared with the case where the recess 10b is not provided, the component of the pulling force acting on the entire crotch leg gather 151 in the direction toward the inner side in the width direction W can be reduced.

[0198] In addition, in the absorbent article 1A, the narrowest portion 10c of the recess 10b is located on the outside of the imaginary center line VC in the width direction W. The imaginary center line VC is a straight line that passes through the center in the width direction W between the portion of the outer end 10a of the leg gather 15 that is located on the outside of the width direction W (that is, the portion of the outer end 10a where the recess 10b is not provided) and the upright fulcrum 16b of the leg side gather 16 and is parallel to the length direction L. According to the above structure, by forming the recess 10b to be relatively small in such a manner that at least the narrowest portion 10c is located on the outside of the imaginary center line VC, the area of ​​the crotch leg gather 151 (that is, as shown in FIG. 1 ) can be ensured. Figure 7 The area exposed at a position further outward than the leg opening 2e of the wearing article 2 as shown in the figure can well suppress the occurrence of side leakage of excrement from the leg gathers 15.

[0199] In addition, when viewed from the thickness direction T, the outer end 131 of the absorbent core 13a in the width direction W has a shape corresponding to the shape of the recess 10b. That is, as also described in the first embodiment, the absorbent core 13a has a narrowed shape, and a recess 132 that is recessed inward in the width direction W is formed at the outer end 131 of the absorbent core 13a. In the length direction L, the position of the narrowest part 10c of the recess 10b and the position of the narrowest part 132a of the recess 132 are roughly consistent with each other. In addition, the recess 132 only needs to have a curved shape similar to the recess 10b, and the depth and shape of the recess 132 may not be completely consistent with the depth and shape of the recess 10b. For example, the recess 10b only needs to be formed so that the deviation of the distance between the outer end 10a of the crotch leg gathers 151 at each position along the length direction L and the outer end 131 of the absorbent core 13a is small. For example, as in the present embodiment, the positions of the narrowest portion 10 c and the narrowest portion 132 a in the longitudinal direction L are substantially consistent with each other, and the narrowing shape of the recess 132 is similar to the narrowing shape of the recess 10 b .

[0200] Assuming that the recessed portion 132 is not provided in the absorbent core 13a, the absorbent core 13a will be folded due to the force applied to the inner side in the width direction W, thereby easily generating a force to pull the lower leg gathers 151 toward the crotch side of the wearer H. On the other hand, by providing the absorbent core 13a with a recessed portion 132 that matches the shape of the thigh H1 of the wearer H as in the present embodiment, the fit of the lower leg gathers 151 is improved, thereby suppressing the deformation of the absorbent core 13a, and as a result, the above-mentioned pulling force can be reduced. In other words, compared with the case where the recessed portion 132 is provided, when the recessed portion 132 is not provided, the distance from the end of the absorbent core 13a in the width direction W to the outer end 10a of the lower leg gathers 151 is shorter. Therefore, it is difficult for the lower leg gathers 151 to be along the thigh H1. By providing the recessed portion 132, the fit with respect to the shape of the thigh portion H1 is improved, so that the contact area between the leg gathers 15 and the skin of the wearer H can be prevented from being reduced, and as a result, the above-mentioned pulling force can be reduced. On the other hand, the width of the absorbent core 13a can be made wider at the end portion in the longitudinal direction L of the absorbent core 13a (that is, the portion where the recessed portion 132 is not formed), so the absorbency of the absorbent core 13a can be ensured. In addition, according to the structure of this embodiment in which the recessed portion 10b of the main body 10 is provided together with the recessed portion 132 of the absorbent core 13a, the following effects can be further achieved. That is, according to the above structure, by forming the shape of the outer end 131 in the width direction W of the absorbent core 13a and the end in the width direction W of the entire absorbent article 1A (that is, the outer end 10a in the width direction W of the leg gathers 15) into the same concave shape, the distance in the width direction W between the outer end 10a of the crotch leg gathers 151 and the outer end 131 of the absorbent core 13a can be made substantially uniform in the longitudinal direction L. As a result, the leg gathers 15 can be well fitted to the thigh H1 of the wearer H. As a result, the occurrence of side leakage of excrement from the leg gathers 15 can be well suppressed.

[0201] In addition, the narrowest portion 10c of the recess 10b is arranged at a position on the outside of the crotch leg gathers 151 in the width direction W relative to the shrinkage member 152. In other words, the shrinkage member 152 constituting the high rigidity portion 151B having relatively high rigidity as described above is provided at a portion on the inside of the recess 10b in the width direction W. In the case where the area of ​​the leg gathers 15 (particularly the crotch leg gathers 151) is reduced due to the recess 10b, a certain degree of rigidity is required for the crotch leg gathers 151 in order to maintain the stability of the crotch leg gathers 151. According to the above structure, since the shrinkage member 152 having relatively high rigidity formed in a sheet shape is arranged at the crotch leg gathers 151, the rigidity of the crotch leg gathers 151 can be ensured. Therefore, while ensuring the stability of the crotch leg gathers 151, the effects (such as the first to third effects described above) produced by providing the recess 10b can be obtained.

[0202] [Modification of the Second Embodiment]

[0203] Reference Fig. 9 The structure of an absorbent article 1B according to a modified example of the second embodiment will be described. Fig. 9 This is a top view of the absorbent article 1B as viewed from the skin side. Fig. 9 As shown in FIG. 1 , the absorbent article 1B is different from the absorbent article 1A in that the absorbent article 1B has a main body 10B having a recess 10b that is larger (deeper) than the recess 10b of the main body 10A. In addition, due to this, the area (length in the width direction W) of the contraction member 152 of the absorbent article 1B is smaller than the area of ​​the contraction member 152 of the absorbent article 1A. The other structures of the absorbent article 1B are the same as those of the absorbent article 1A.

[0204] In the absorbent article 1B, the narrowest portion 10c of the recess 10b is located on the inner side of the imaginary center line VC in the width direction W. According to the above structure, the recess 10b is formed relatively large, and the outer end 10a of the crotch gather 151 is as close to the crotch of the wearer H as possible, so that the above-mentioned first to third effects can be well exerted.

[0205] [Third embodiment]

[0206] Reference Fig.10 The structure of an absorbent article 1C according to the third embodiment will be described. Fig.10 This is a plan view of the absorbent article 1C as viewed from the skin side.

[0207] The absorbent article 1C is different from the absorbent article 1 in that it is configured as follows, and the other structures are the same as those of the absorbent article 1. The absorbent article 1C has a main body 10C instead of the main body 10. The main body 10C has one or more slits S provided in each leg gather 15 (crotch leg gather 151) of a pair of leg gathers 15 (crotch leg gather 151). The slits S function as one of the suppressing mechanisms.

[0208] In the present embodiment, a plurality of (two) slit portions S1 and S2 are provided in each leg gather 15. The slit portions S1 and S2 are provided at positions that divide the leg gather 15 into three equal parts in the length direction L, and the slit portion S1 is provided at a position closer to the ventral side than the slit portion S2. Each slit portion S is a cut extending from the outer end portion 10a in the width direction W of the crotch leg gather 151 to the inner side in the width direction W. In the present embodiment, the leg gather 15 is partially separated into a portion 15A from the ventral end portion to the slit portion S1, a portion 15B between the slit portions S1 and S2, and a portion 15C from the slit portion S2 to the dorsal end portion.

[0209] In the present embodiment, each slit portion S extends to a position that is more inside than the center position in the width direction W of the leg gather 15, but does not reach the inner end portion 152b of the contraction member 152. That is, the slit portions S1 and S2 partially separate the contraction member 152. However, the length of the slit portion S is not limited to the above-mentioned manner. The end portion of the slit portion S may be located at a position that is more outside than the center position in the width direction W of the leg gather 15, or may be located at a position that is more inside than the inner end portion 152b of the contraction member 152. In the latter case, the contraction member 152 is completely separated (cut) in the length direction L by the slit portion S.

[0210] According to the absorbent article 1C, the crotch leg gathers 151 and the contraction member 152 can be separated into a plurality of parts (in the present embodiment, the part belonging to the part 15A, the part belonging to the part 15B, and the part belonging to the part 15C) in the length direction L by using the slit portion S. Thus, in the case where a pulling force is generated on one part to pull it toward the crotch portion, other parts can be prevented from being pulled toward the crotch portion in conjunction with the one part. That is, in the case where a pulling force is generated on any part of the crotch leg gathers 151, the influence range of the pulling force can be limited to the part, and the pulling force can be prevented from being transmitted to other adjacent parts. As a result, the crotch leg gathers 151 can be effectively prevented from being pulled toward the crotch portion.

[0211] In addition, when the crotch leg gathers 151 are separated into a plurality of parts by the slit portion S, a certain degree of rigidity is required for each part in order to maintain the stability of each part. Here, in the absorbent article 1C, as described above, the high rigidity part 151B is formed by the shrinking member 152 formed as an integral sheet-like member. That is, since the shrinking member 152 having relatively high rigidity is partially arranged in each part separated by the slit portion S, the rigidity of each part can be ensured. Therefore, according to the absorbent article 1C, the above-mentioned effect can be obtained by providing the slit portion S while ensuring the stability of each part separated by the slit portion S.

[0212] [Modifications]

[0213] Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to the above embodiments. The materials and shapes of each structure are not limited to the above materials and shapes, and various materials and shapes can be adopted.

[0214] Parts of the structures shown in each of the first to third embodiments may also be applied to other embodiments. For example, the slit portion S shown in the third embodiment may be provided in the absorbent article 1B of the second embodiment. That is, both the recess 10b and the slit portion S may be provided in the absorbent article.

[0215] Parts of the structures shown in each of the first to third embodiments may also be changed or omitted. For example, in the absorbent article 1C of the third embodiment, there is a possibility that since the leg gathers 15 are partially separated by the slit portion S, the influence of the counterforce generated by the anti-drift portion 60 is limited to the portion 15C where the anti-drift portion 60 is arranged, and has almost no influence on the portion 15B. In other words, it is believed that the effect of the anti-drift portion 60 as a suppressing mechanism when the slit portion S is provided is smaller than the effect when the slit portion S is not provided. Based on this idea, the anti-drift portion 60 may also be omitted in the absorbent article 1C.

[0216] Furthermore, in the above-described embodiment, the wearing article 2 is a belt-type cloth underwear, but the wearing article 2 may be a panty-type cloth underwear.
