Description

[Technical field]

[0001] The present invention relates to an absorbent article. [Background technology]

[0002] As an absorbent article, an absorbent pad having a vertically elongated pad shape is known. The vertical contour line of the absorbent pad disclosed in Patent Document 1 has a first convex portion that convex toward the inside in the horizontal direction in the crotch portion and a second convex portion that convex toward the outside in the horizontal direction in the back portion. By forming such a shape in which the vertical center portion is narrowed, the absorbent pad is less likely to get caught on the wearer's thighs and is more likely to adhere to the area from the crotch portion to the buttocks of the wearer. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2022-143208 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the absorbent pad of Patent Document 1, the shortest part of the horizontal length is located closer to the back side than the vertical center line that divides the absorbent pad vertically in half. In other words, the vertical contour line of the absorbent pad is most deeply constricted on the back side. Therefore, when the absorbent pad is viewed in plan, the user can easily recognize that the area of ​​the back side of the absorbent pad is small. This may cause the user to feel uneasy that the absorbent pad cannot wrap around the buttocks and excreted liquid will leak. In fact, if the width of the back side of the absorbent pad is small, excreted liquid is more likely to leak sideways when the user is in a lateral position, etc.

[0005] Therefore, the present invention has been made in consideration of the above-mentioned problems, and aims to provide an absorbent article that fits well around the wearer's crotch, is less likely to leak excreted liquid, and reduces the user's visual anxiety about leakage. [Means for solving the problem]

[0006] The main invention to achieve the above object is: In the deployed state, the bag has a front-rear direction, a width direction, and a thickness direction which are perpendicular to each other, 1. An absorbent article having an absorbent core, comprising: In a crotch portion located under the crotch of a wearer when worn, an outer edge of the absorbent article has a constricted portion constricted on the inside in the width direction, The constricted portion has a narrowest portion having a narrowest length in the width direction, The outer edge of the absorbent article has an extension portion that extends outward from an imaginary line connecting a rear end of the narrowest portion in the front-rear direction and a rear end of the constricted portion in the front-rear direction. The absorbent article is characterized by the above. Other features of the present invention will become apparent from the following detailed description of the present invention and the accompanying drawings. Effect of the Invention

[0007] According to the present invention, it is possible to provide an absorbent article which fits well around the crotch of a wearer, is less susceptible to leakage of excreted liquid, and reduces the user's visual anxiety about leakage. [Brief description of the drawings]

[Figure 8] FIG. 4 is an explanatory diagram of the leakage preventing wall portion 6. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] At least the following points will become apparent from the description of this specification and the accompanying drawings. (Aspect 1) An absorbent article having an absorbent core and having, in an unfolded state, a front-to-rear direction, a width direction, and a thickness direction which are perpendicular to each other, wherein in a crotch portion which is located under the crotch of a wearer when worn, the outer edge of the absorbent article has a constricted portion which is constricted on the inside in the width direction, and the constricted portion has a narrowest portion which has the narrowest length in the width direction, and the outer edge of the absorbent article has an extension portion which extends outward beyond an imaginary line connecting the rear end of the narrowest portion in the front-to-rear direction and the rear end of the constricted portion in the front-to-rear direction.

[0010] According to the first aspect, the constricted portion improves the fit of the absorbent article around the crotch of the wearer. Meanwhile, the extended portion increases the width of the absorbent article at a steep incline, and the plane area of ​​the absorbent article on the rear side of the narrowest portion is larger. This makes it possible to suppress leakage of excreted liquid and visually reduce the user's anxiety about leakage.

[0011] (Aspect 2) The absorbent article according to aspect 1, When a position shifted outward in the width direction from the rear end of the narrowest portion by an amount obtained by dividing the width direction length from the rear end of the narrowest portion to the rear end of the constricted portion into thirds is defined as a first position, the constricted portion has a first constricted portion that is constricted inward in the width direction from the first position, and a second constricted portion which is all the portion other than the first constricted portion, and the front-to-rear length of the first constricted portion is shorter than the front-to-rear length of the second constricted portion.

[0012] According to the second aspect, the shallowly constricted second constricted portion is present over a wide area in the front-to-rear direction of the constricted portion, which increases the plane area of ​​the absorbent article at the constricted portion, thereby preventing leakage of excreted liquid and visually reducing the user's anxiety about leakage.

[0013] (Aspect 3) An absorbent article according to aspects 1-2, At least a portion of the extension portion is located forward of a center position of the narrowed portion in the front-rear direction.

[0014] According to the third aspect, the width of the absorbent article is increased in front of the constricted portion, and the plane area of ​​the absorbent article is increased behind the constricted portion, thereby preventing leakage of excreted liquid and visually reducing the user's anxiety about leakage.

[0015] (Aspect 4) An absorbent article according to any one of aspects 1 to 3, The outer edge of the absorbent article has a non-extending portion that is constricted inwardly of the imaginary line and rearwardly of the extending portion in the front-rear direction.

[0016] According to the fourth aspect, an increase in the width of the absorbent article that is suddenly enlarged at the extension portion is suppressed, thereby ensuring a good fit of the absorbent article around the crotch area of ​​the wearer.

[0017] (Aspect 5) An absorbent article according to any one of aspects 1 to 4, When the central position in the width direction between the rear end of the narrowest portion and the rear end of the constricted portion is defined as a second position, the extension portion located furthest forward in the front-to-rear direction is located more inward in the width direction than the second position.

[0018] According to aspect 5, the protrusion of the absorbent article at the extension portion is small, and an increase in the width of the absorbent article is appropriately suppressed, thereby ensuring a good fit of the absorbent article around the crotch area of ​​the wearer.

[0019] (Aspect 6) An absorbent article according to any one of aspects 1 to 5, When a position shifted outward in the width direction from the rear end of the narrowest portion by an amount equal to the widthwise length from the rear end of the narrowest portion to the rear end of the constricted portion divided into thirds is defined as a first position, the constricted portion has a first constricted portion that is constricted inward in the width direction from the first position, the rear end of the constricted portion is located rearward in the front-to-back direction from the front-to-back center position of the absorbent article, and the front-to-back length from the rear end of the constricted portion to the front-to-back center position of the absorbent article is shorter than the front-to-back length of the first constricted portion that is located furthest forward in the front-to-back direction.

[0020] According to the sixth aspect, the constricted portion is located toward the front of the absorbent article, and the width of the rear portion of the absorbent article is increased, thereby suppressing leakage of excreted liquid. Also, visually, the user is more likely to feel that the absorbent article extends further toward the rear, which reduces the user's anxiety about leakage.

[0021] (Aspect 7) The absorbent article according to aspect 4, The outer edge of the absorbent article has, in the non-extending portion, a straight portion along the front-rear direction and an inclined portion inclined outward in the width direction toward the rear end of the constricted portion.

[0022] According to aspect 7, the straight portion prevents an increase in the width of the absorbent article, thereby ensuring a good fit of the absorbent article around the crotch area of ​​the wearer.

[0023] (Aspect 8) An absorbent article according to any one of aspects 1 to 7, It has an overlapping region that overlaps with the extension portion in the front-to-back direction, and an adjacent region that is adjacent to the overlapping region from the rear side in the front-to-back direction and has the same length in the front-to-back direction as the overlapping region, and the overlapping region and the adjacent region each have a non-existent region on one side in the width direction where the absorbent core is not present, and the area of ​​the non-existent region in the overlapping region is larger than the area of ​​the non-existent region in the adjacent region.

[0024] According to aspect 8, the outer edge of the absorbent article protrudes firmly from the extension portion, visually reducing the user's anxiety about leakage. Meanwhile, the outer edge of the absorbent core is prevented from protruding, improving the fit of the absorbent core around the wearer's crotch.

[0025] (Aspect 9) An absorbent article according to any one of aspects 1 to 4 and aspects 6 to 8, When the central position in the width direction between the rear end of the narrowest portion and the rear end of the constricted portion is defined as a second position, the outer end in the width direction of the extension portion located most forward in the front-to-rear direction is located at the second position or further outboard in the width direction than the second position.

[0026] According to the ninth aspect, the absorbent article protrudes firmly from the extension portion, and the width of the absorbent article increases. Therefore, the plane area of ​​the absorbent article on the rear side of the narrowest portion increases, which can suppress leakage of excreted liquid and visually reduce the user's anxiety about leakage.

[0027] (Aspect 10) An absorbent article according to any one of aspects 1 to 9, The absorbent article has a line that is visible from the skin side and extends along the front-to-rear direction, and the line overlaps with the center of the absorbent core in the width direction in the thickness direction.

[0028] According to the tenth aspect, the user (wearer or caregiver, etc.) can use the line as a guide to place the absorbent article straight against the wearer's length and bring the widthwise center of the absorbent core into contact with the center of the wearer's crotch (excretory opening). This makes it difficult for the absorbent article to get caught on the wearer's thighs, improving the fit of the absorbent core to the wearer's crotch. In addition, the absorbent core can receive and absorb excreted liquid securely, suppressing leakage of excreted liquid.

[0029] (Aspect 11) An absorbent article according to any one of aspects 1 to 10, When a position shifted outward in the width direction from the rear end of the narrowest portion by an amount obtained by dividing the width direction length from the rear end of the narrowest portion to the rear end of the constricted portion into thirds is defined as a first position, the constricted portion has a first constricted portion that is constricted inward in the width direction from the first position, and the fore-aft length of the first constricted portion that is located furthest forward in the fore-aft direction is less than the width direction length from the rear end of the narrowest portion to the rear end of the constricted portion.

[0030] According to the eleventh aspect, the length of the first constricted portion in the front-rear direction is shortened, and the width of the absorbent article can be increased at a steep incline. Therefore, an extension portion can be formed, and the plane area of ​​the absorbent article on the rear side of the narrowest portion becomes larger.

[0031] (Aspect 12) An absorbent article according to any one of aspects 1 to 11, The absorbent core has a core constricted portion in the crotch portion, the outer edge of which is constricted inward in the width direction, and a core narrowest portion in the core constricted portion, where the length of the absorbent core in the width direction is narrowest, and the outer edge of the absorbent core does not extend outward from a second imaginary line connecting the rear end of the core narrowest portion in the front-to-rear direction and the rear end of the core constricted portion in the front-to-rear direction.

[0032] According to aspect 12, the protrusion of the outer edges of the absorbent core is suppressed, improving the fit of the absorbent core around the wearer's crotch.

[0033] (Aspect 13) An absorbent article according to any one of aspects 1 to 12, The length in the front-to-rear direction when unfolded and extended is 640 mm or more, and the absorbent pad is for adults.

[0034] According to aspect 13, compared to when the front-to-rear length of the absorbent article is less than 640 mm, leakage of excreted liquid in the front-to-rear direction can be suppressed even when worn by an adult with a large amount of excretion, and the user's anxiety about leakage can be visually reduced.

[0035] (Aspect 14) An absorbent article according to any one of aspects 1 to 11 and aspect 13, The absorbent core has, in the crotch portion, a core constricted portion whose outer edge is constricted inward in the width direction, and a core narrowest portion in the core constricted portion where the length of the absorbent core in the width direction is narrowest, and the outer edge of the absorbent core has a core extension portion that extends outward from a second imaginary line connecting the rear end of the core narrowest portion in the front-to-rear direction and the rear end of the core constricted portion in the front-to-rear direction, but the front-to-rear length of the core extension portion is shorter than the front-to-rear length of the extension portion.

[0036] According to the fourteenth aspect, the protrusion of the outer edge of the absorbent core is suppressed, thereby improving the fit of the absorbent core around the crotch of the wearer.

[0037] (Aspect 15) An absorbent article according to any one of aspects 1 to 14, The absorbent core has a core constriction portion in the crotch portion, the outer edge of which is constricted inward in the width direction, and has leakage prevention wall portions at the sides in the width direction that can stand up against the skin, the core constriction portion has a first core constriction portion that is constricted inward in the width direction further than the position of the starting point of the leakage prevention wall portions in the width direction, and the front-to-back length of the first core constriction portion is less than half the front-to-back length of the core constriction portion.

[0038] According to aspect 15, the absorbent core can support the rising starting points of the leakage preventing walls from below over a wide range in the front-to-rear direction of the constricted core portion, so that the leakage preventing walls can rise stably on the highly rigid absorbent core.

[0039] === Implementation form === Hereinafter, an embodiment will be described taking an absorbent pad (urine pad) for adults as an example of an absorbent article. However, the absorbent article is not limited to the above, and may be, for example, a tape-type disposable diaper, a pants-type disposable diaper, a sanitary napkin, a panty liner, a shorts-type napkin, a light incontinence pad, etc. Furthermore, the wearer of the absorbent article is not limited to adults, but may be a child or a pet.

[0040] <<Basic configuration of absorbent pad 1>> Fig. 1 is a plan view of an absorbent pad 1 in an expanded and stretched state, as viewed from the skin side. Fig. 2 is a schematic cross-sectional view of the absorbent pad 1 taken along line II in Fig. 1.

[0041] In the following description, the absorbent pad 1 is also referred to as "pad 1." The developed state of the pad 1 refers to the state in which the entire pad 1 is developed in a plane. The extended state refers to the state in which the pad 1 is extended to such an extent that wrinkles that have occurred in the pad 1 are substantially invisible, and the pad 1 is extended to such an extent that the dimensions of each member constituting the pad 1 (e.g., side sheet 5 described below, etc.) match or are close to the dimensions of the member alone. When the absorbent article is a pants-type (shorts-type) absorbent article, the developed state refers to the state in which the side joints provided on both sides of the absorbent article are separated, the absorbent article is opened, and developed in a plane.

[0042] In the developed state, the pad 1 has a front-rear direction, a width direction, and a thickness direction that are perpendicular to each other. The front-rear direction corresponds to the longitudinal direction of the absorbent body 10 described later. The front side in the front-rear direction corresponds to the abdominal side of the wearer when worn, and the rear side corresponds to the dorsal side of the wearer. In the thickness direction, the side that comes into contact with the wearer's skin is referred to as the skin side, and the opposite side is referred to as the non-skin side.

[0043] In addition, the part between both ends of the pad 1 in the front-rear direction and located under the crotch of the wearer when worn is also referred to as "crotch part 1m". The crotch part 1m may be, but is not limited to, the central part obtained by dividing the pad 1 into thirds in the front-rear direction. For example, the length of the crotch part 1m in the front-rear direction may be shorter or longer than the length obtained by dividing the pad 1 into thirds in the front-rear direction, and in a pad that extends further toward the rear, the crotch part 1m may be located toward the front.

[0044] As shown in FIG. 2, the pad 1 comprises an absorbent body 10, a liquid-permeable surface sheet 2 (e.g., a nonwoven fabric or a perforated film) provided on the skin side of the absorbent body 10, a liquid-impermeable or liquid-difficult-to-permeable back sheet 3 (e.g., a resin film) provided on the non-skin side of the absorbent body 10, an exterior sheet 4 (e.g., a nonwoven fabric) provided on the non-skin side of the back sheet 3, and a pair of side sheets 5 (e.g., a hydrophobic nonwoven fabric) provided on both sides of the surface sheet 2 in the width direction.

[0045] The absorbent body 10 has an absorbent core 11 and a core wrap sheet 12. The absorbent core 11 has a two-layer structure, and has an upper absorbent core 111 provided on the skin side and a lower absorbent core 112 provided on the non-skin side. Examples of the upper absorbent core 111 and the lower absorbent core 112 include liquid-absorbent fibers such as pulp fibers containing SAP (super absorbent polymer) molded into a predetermined shape. The core wrap sheet 12 has an upper core wrap sheet 121 that covers the skin side of the upper absorbent core 111, and a lower core wrap sheet 122 that wraps the skin side and non-skin side of the lower absorbent core 121. Examples of the core wrap sheet 12 include liquid-permeable tissue and nonwoven fabric.

[0046] The upper absorbent core 111 and the lower absorbent core 112 have slits 111s, 112s extending in the front-to-rear direction at the center of the width of the crotch portion 1m. The slits 111s, 112s become folding starting points, and the upper absorbent core 111 and the lower absorbent core 112 are easily deformed to encase the crotch of the wearer.

[0047] However, the configuration of the absorbent body 10 is not limited to the above. For example, the absorbent core may be configured of one layer, may not have the slits 111s, 112s, and may not be covered with the core wrap sheet 12. The absorbent core may also be an SAP sheet in which an SAP layer is attached to a hydrophilic sheet, or an airlaid sheet in which liquid absorbent fibers are formed into a sheet shape by an airlaid method. The upper absorbent core 111 and the lower absorbent core 112 may each be made of different absorbent materials.

[0048] The pad 1 also has a pair of leak-preventing walls 6 that can stand up on the skin side on both sides in the width direction. The leak-preventing walls 6 are formed by a side sheet 5 and a leak-preventing wall elastic member 7 such as rubber thread. The leak-preventing wall elastic member 7 is fixed in a stretched state along the front-rear direction to the folded-back portion of the inner end of the side sheet 5 in the width direction.

[0049] Although the basic configuration of the pad 1 has been described above, the above configuration of the pad 1 is merely an example and is not intended to be limiting. For example, the pad may have no leak-proof wall portion 6 or no exterior sheet 4.

[0050] ===About the outer shape of absorbent pad 1=== 3 to 5 are explanatory diagrams of the outer shape of the pad 1. Figures 6A and 6B are explanatory diagrams of a modified example of the pad 1.

[0051] As shown in FIG. 3, in the crotch portion 1m of the pad 1, the outer edge 1E of the pad 1 (specifically, the side edge of the outer contour of the pad 1 extending in the front-rear direction) has a "constricted portion Dc" that is constricted inward in the width direction. The constricted portion Dc shortens the width of the pad 1 at the wearer's crotch, making it difficult for the pad 1 to deform chaotically even when the wearer closes his / her legs. As a result, a gap is unlikely to be formed between the pad 1 and the wearer, improving the fit of the pad 1 to the wearer's crotch. Furthermore, when a caregiver applies the pad 1 to a wearer (care recipient) in a lying position, the pad 1 is unlikely to get caught on the thighs, and the pad 1 can be worn appropriately without any gaps.

[0052] The constricted portion Dc is an area where the width of the pad 1 is shorter than the adjacent areas in the front-rear direction. Therefore, the front end Dcf (the beginning of constriction) and the rear end Dcb (the end of constriction) of the constricted portion Dc in the front-rear direction are positions where the inclination of the tangent to the outer edge 1E of the pad 1 changes. In other words, the front end Dcf and the rear end Dcb of the constricted portion Dc are the inflection points where the inclination changes from an inclination outward in the width direction toward the center in the front-rear direction or from an inclination along the front-rear direction to an inclination inward in the width direction toward the center in the front-rear direction.

[0053] The pad 1 has a "narrowest part N" in the narrowed part Dc, which has the narrowest widthwise length (W0 in FIG. 3). The outer edge 1E of the pad 1 has an "extending part E" that extends outward from a virtual line VL that connects a rear end Nb of the narrowest part N in the front-rear direction and a rear end Dcb of the narrowed part Dc in the front-rear direction. In other words, the extending part E is provided in the narrowed part Dc, rearward of the narrowest part N, so that the outer edge 1E of the pad 1 protrudes outward in the widthwise direction.

[0054] 3 is one point. Therefore, the narrowest part N corresponds to the rear end Nb of the narrowest part. However, the narrowest part N may have a length in the front-rear direction. In that case, a virtual line VL is determined from the rear end Nb of the narrowest part N.

[0055] In addition, when the pad 1 is in an unfolded and extended state, a virtual line VL is defined, and the presence or absence of the extended portion E is confirmed. The presence or absence of portions of the pad 1 described below (for example, a non-extended portion NE and a core constricted portion 11c described below, etc.) and comparison of the lengths and positions of each portion are also confirmed when the pad 1 is in an unfolded and extended state.

[0056] The fact that the outer edge 1E of the pad 1 (the outer contour of the product) has the extension portion E means that the width of the pad 1 does not gradually increase from the narrowest portion N toward the rear end Dcb of the constricted portion Dc, but there is a portion where the width increases abruptly (a portion where the width of the pad 1 increases at a steep incline). In this case, a user (e.g., a wearer or a caregiver) who sees the pad 1 in a plan view is more likely to feel that the plane area of ​​the pad 1 behind the narrowest portion N is larger than when the width of the pad 1 increases gradually. In other words, due to the optical illusion effect, the user is more likely to feel that the pad 1 extends longer behind the narrowest portion N and that the plane area of ​​the extended portion is larger. Therefore, the pad 1 can give the user the impression that it fits around the buttocks, and the user's anxiety about leakage when he or she spreads out the pad 1 before use can be reduced. Therefore, the user can use the pad 1 with confidence. In fact, compared to when the width of the pad 1 increases gradually, the pad 1 extends beyond the virtual line VL at the extension portion E (the shaded portion in FIG. 3), so that the plane area of ​​the pad 1 behind the narrowest portion N is larger. In this way, leakage of excrement can be suppressed by ensuring the outer surface area of ​​the pad 1 without the constricted portion Dc being too constricted. In particular, since the width of the pad 1 from the crotch portion 1m that receives excrement to the rear side is ensured, side leakage of excrement can be suppressed even when the wearer is in a lateral position.

[0057] The outer shape of the pad 1 illustrated in Fig. 3 is symmetrical in the width direction. Therefore, the outer edge 1E of the pad 1 has an extension E on both sides in the width direction. However, this is not limited thereto, and the pad 1 may have an asymmetric shape in the width direction, as long as the outer edge 1E of the pad 1 has an extension E on at least one side in the width direction.

[0058] In addition, the outer edge 1E of the pad 1 in this embodiment has a shape in which the rear end of the constricted portion Dc is convex outward in the width direction. Therefore, as shown in Fig. 5, a small extension portion E2 is present at the rear end of the constricted portion Dc. In other words, the outer edge 1E of the pad 1 has an extension portion E1 that is long in the front-rear direction near the narrowest portion N, and a small extension portion E2 at the rear end of the constricted portion Dc. However, the number of extension portions E that the outer edge 1E of the pad 1 has is not limited, and may be one or more.

[0059] In addition, the pad 1 of this embodiment is an absorbent pad for adults, with a length (product length) La in the front-rear direction in the unfolded and extended state being 640 mm or more (La≧640 mm) as shown in FIG. 1. In this case, leakage of excreted liquid in the front-rear direction can be suppressed even when worn by an adult with a large amount of excretion, compared to when the product length La is less than 640 mm. In addition, the longer product length La can visually reduce the user's anxiety about leakage. However, this is not limited thereto, and the product length La of the pad 1 may be less than 640 mm, and the pad may be an absorbent pad for children.

[0060] Unlike tape-type disposable diapers and pants-type diapers, the pad 1 is attached without being connected at its front end and rear end along the wearer's waist. The pad 1 may be disposed inside the diaper and used in combination with the diaper, or may be disposed directly inside the wearer's underwear and used alone. Even when the pad 1 is used in combination with the diaper, the pad 1 can reduce the number of diaper changes by suppressing leakage of excreted liquid from the pad 1 into the diaper, thereby simplifying excretion processing.

[0061] 3, it is preferable that at least a part of the extension E is located forward of the center position DcC of the constricted portion Dc in the front-rear direction. By doing so, the width of the pad 1 increases at a steep incline in front of the constricted portion Dc, and the length in the front-rear direction of the deeply constricted portion such as the narrowest portion N can be shortened. Therefore, the width of the pad 1 increases from a position closer to the front of the constricted portion Dc, and leakage of excreted liquid can be suppressed. Furthermore, visually, the user is likely to perceive that the pad 1 extends rearward from the narrowest portion N closer to the front, and that the plane area of ​​the extended portion is large, which can reduce anxiety about leakage.

[0062] In the above case, the length in the front-rear direction of the deeply constricted portion including the narrowest portion N is shortened. Therefore, the narrowest portion N and the portion nearby have a notch shape (approximately triangular) that protrudes inward in the width direction. Therefore, the pad 1 is easily folded in the front-rear direction with the narrowest portion N as the folding starting point, and the pad 1 is easily deformed three-dimensionally from the lower abdomen to the crotch of the wearer. However, this is not limited to the above, and the extension region E may be located behind the center position DcC of the constricted portion Dc.

[0063] In addition, the outer edge 1E of the pad 1 preferably has a non-extending portion NE that is constricted inward from the virtual line VL on the rear side of the extending portion E in the front-rear direction. That is, the outer edge 1E of the pad 1 has an extending portion E that is convex outward in the width direction and a non-extending portion NE that is convex inward in the width direction on the rear side of the narrowest portion N. In the constricted portion Dc of the pad 1 illustrated in FIG. 3, the outer edge 1E of the pad 1 is deeply constricted from its front end Dcf toward the narrowest portion N, and the width of the pad 1 becomes shorter. At the rear side, the outer edge 1E of the pad 1 suddenly widens, and the pad 1 protrudes to form the extending portion E. At the rear side, the outer edge 1E of the pad 1 is kept shallowly constricted, and the outer edge 1E of the pad 1 is located inside the virtual line VL, and the non-extending portion NE is formed. At the rear end of the non-extending portion NE, the outer edge 1E of the pad 1 is inclined outward in the width direction toward the rear end Dcb of the constricted portion Dc.

[0064] The non-extended portion NE is provided to suppress an increase in the width of the pad 1 that is suddenly enlarged at the extended portion E. As a result, the width of the pad 1 does not become too large behind the narrowest portion N, and a region (Dc0 in FIG. 3) where the shallow constricted state continues is formed. This increases the planar area of ​​the pad 1 at the constricted portion Dc while also ensuring the fit of the pad 1 around the crotch of the wearer.

[0065] However, the present invention is not limited to the above, and as shown in Fig. 6A of a modified example, the outer edge 1E of the pad 1 may not have the non-extended portion NE. In this case, the width of the pad 1, which is suddenly enlarged at the extended portion E, continues to increase, so that the planar area of ​​the pad 1 at the constricted portion Dc becomes larger. This makes it possible to suppress leakage of excreted liquid and visually reduce the user's anxiety about leakage.

[0066] 3, the shallowly constricted portion (Dc0) of the constricted portion Dc is located across the extended portion E and the non-extended portion NE, and the shallowly constricted portion (Dc0) has a constant width of the pad 1. In this manner, the outer edge 1E of the pad 1 may have, in the non-extended portion NE, a straight portion NE1 along the front-to-rear direction and an inclined portion NE2 inclined outward in the width direction toward the rear end Dcb of the constricted portion Dc.

[0067] By doing so, the width of the pad 1 is kept constant by the straight line portion NE1 after it suddenly expands at the extension portion E. Therefore, the width of the pad 1 does not become too large behind the narrowest portion N, and a shallowly constricted portion (Dc0) can be formed. This ensures the pad 1 fits snugly around the crotch of the wearer.

[0068] However, the present invention is not limited to the above, and the non-extending portion NE does not have to have a straight portion NE1 along the front-rear direction. For example, the shallowly constricted portion (Dc0) may be inclined outward in the width direction toward the rear. The inclination angle is preferably smaller than the inclination angle of the rear portion (inclined portion NE2) of the non-extending portion NE. In this way, the shallowly constricted portion (Dc0) can be formed, and the fit of the pad 1 to the crotch of the wearer can be ensured.

[0069] Here, as shown in FIG. 4, a position shifted outward in the width direction from the rear end Nb of the narrowest portion N by a length (Wa / 3) obtained by dividing the width direction length from the rear end Nb of the narrowest portion N to the rear end Dcb of the constricted portion Dc into thirds is defined as the first position. In this case, the constricted portion Dc has a first constricted portion Dc1 constricted inward in the width direction from the first position, and a second constricted portion Dc2 which is the entire portion other than the first constricted portion Dc1. In other words, the first constricted portion Dc1 is a portion constricted deeper than a third virtual line VL3 extending along the front-rear direction at the first position. On the other hand, the second constricted portion Dc2 is a portion constricted shallower than the third virtual line VL3.

[0070] The length L1 of the first constricted portion Dc1 in the front-rear direction is preferably shorter than the length of the second constricted portion Dc2 in the front-rear direction (L1 < L0 - L1). The length of the second constricted portion Dc2 in the front-rear direction is the length obtained by subtracting the length L1 of the first constricted portion Dc1 in the front-rear direction from the length L0 of the entire constricted portion Dc in the front-rear direction (L0 - L1). Note that, as shown in FIG. 4, when there are a plurality of second constricted portions Dc2 separated in the front-rear direction, comparison is made based on the total length of the plurality of second constricted portions Dc2. Similarly, when there are a plurality of first constricted portions Dc1, comparison is made based on the total length.

[0071] According to the above, a portion where the width of the pad 1 is relatively wide (the second constricted portion Dc2) exists over a wide range in the front-rear direction of the constricted portion Dc. Therefore, even in the constricted portion Dc, an appropriate width of the pad 1 is ensured, and the planar area of the pad 1 becomes large. Therefore, leakage of excreted liquid can be suppressed, and visually, the user's anxiety about leakage can be reduced. Further, since the length L1 of the first constricted portion Dc1 in the front-rear direction is short, the first constricted portion Dc1 has a notch shape. Thus, the pad 1 can be easily folded in the front-rear direction with the narrowest portion N as the folding starting point.

[0072] Also, as shown in FIG. 3, the center DcC of the constricted portion Dc in the front-rear direction is preferably located on the front side of the central position CL in the front-rear direction of the pad 1 (that is, the product center line along the width direction that bisects the pad 1 in the front-rear direction). That is, it is preferable that the constricted portion Dc is formed closer to the front of the pad 1. Generally, the user wears the pad 1 such that the constricted portion Dc abuts against the wearer's crotch. Therefore, the pad 1 abuts against the wearer's back side for a long time, and leakage from the back can be suppressed. In particular, leakage during the sleeping posture can be suppressed. Further, since the length of the pad 1 on the rear side of the constricted portion Dc is long, visually, the user's anxiety about leakage from the back can be reduced.

[0073] However, the rear end Dcb of the constricted portion Dc is preferably located on the rear side in the front-rear direction of the central position CL in the front-rear direction of the pad 1. By doing so, it is possible to prevent the constricted portion Dc from being disposed too much to the front side, and the lower abdomen of the wearer can be covered with the pad 1. Therefore, leakage from the front of excreted liquid can be suppressed.

[0074] On the other hand, as shown in FIG. 4, it is preferable that the length L2 in the front-rear direction from the rear end Dcb of the constricted portion Dc to the center position CL in the front-rear direction of the pad 1 is shorter than the length L1 in the front-rear direction of the first constricted portion Dc1 (L2 <L1)。

[0075] By doing so, the rear end Dcb of the constricted portion Dc is located near the center position CL of the pad 1, and the constricted portion Dc is located closer to the front of the pad 1. Therefore, the width of the pad 1 on the rear side of the center position CL becomes wider, and the pad 1 is worn to envelop the wearer's buttocks, thereby suppressing leakage of excreted fluid. Visually, the user is more likely to feel that the pad 1 extends longer toward the rear, which reduces anxiety about leakage. Note that, unlike the pad 1 in FIG. 4, when there are multiple first constricted portions Dc1 spaced apart in the front-to-rear direction, the comparison is made based on the length L1 of the first constricted portion Dc1 located furthest forward in the front-to-rear direction.

[0076] Moreover, it is preferable that the length L1 in the front-rear direction of the first constricted portion Dc1 located at the frontmost side is equal to or less than the length Wa in the width direction from the rear end Nb of the narrowest portion N to the rear end Dcb of the constricted portion Dc, that is, the depth Wa of the constricted portion Dc (L1≦Wa). For this reason, in the pad 1 illustrated in FIG. 4, the bottom of the outer edge 1E of the first constricted portion Dc1 (the portion convex inward in the width direction) is inclined in an arc shape with R10 mm or less (radius 10 mm or less).

[0077] As a result, the length (L1) of the base of the first constricted portion Dc1, which is a notch shape (approximately triangular), is shortened. Therefore, the inclination of the outer edge 1E1 of the pad 1 relative to the front-rear direction at the first constricted portion DC1 becomes greater. In other words, the width of the pad 1 can be increased at a steep incline from the narrowest portion N, forming the extension portion E. This makes it possible to increase the planar area of ​​the pad 1 behind the narrowest portion N, thereby suppressing leakage of excreted liquid and visually reducing the user's anxiety about leakage.

[0078] Here, as shown in Fig. 5, the center position in the width direction between the rear end Nb of the narrowest portion N and the rear end Dcb of the narrowest portion Dc is defined as the "second position." In this case, in the pad 1 shown in Fig. 5, the extension portion E1 located at the front-to-rear direction is located on the inner side in the width direction than the second position. In other words, the extension portion E1 is narrowed deeper than the fourth imaginary line VL4 along the front-to-rear direction at the second position.

[0079] In this case, the protrusion of the pad 1 is small even in the extension portion E, and an increase in the width of the pad 1 behind the narrowest portion N is appropriately suppressed. Therefore, the pad 1 fits snugly around the crotch of the wearer.

[0080] 6B, the outer end 1Ee in the width direction of the extension E1 located at the frontmost side in the front-rear direction, i.e., the outer end 1Ee in the width direction of the outer edge 1E of the pad 1, may be located outboard in the width direction from the second position. Alternatively, the outer end 1Ee may be located at the second position in the width direction (on the fourth imaginary line VL4).

[0081] In this case, the pad 1 protrudes firmly at the extension portion E, and the width of the pad 1 becomes longer. Therefore, the plane area of ​​the pad 1 on the rear side of the narrowest portion N becomes larger, which can suppress leakage of excreted liquid and visually reduce the user's anxiety about leakage.

[0082] 7 is an explanatory diagram of the outer shape of the absorbent core 11. The pad 1 has an overlapping region Ro that overlaps with the extension portion E in the front-to-rear direction, and an adjacent region Ra that is adjacent to the overlapping region Ro from the rear side in the front-to-rear direction and has the same length L4 in the front-to-rear direction as the overlapping region Ro. More specifically, the region of the outer edge 1E of the pad 1 from the front-to-rear position of the front end 1Ef of the extension portion E to the front-to-rear position of the rear end 1Eb of the extension portion E becomes the overlapping region Ro.

[0083] The overlapping region Ro and the adjacent region Ra each have a non-existent region n11 where the absorbent core 11 is not present, on one side in the width direction. The non-existent region n11 is a region between the outer edge 1E (side edge) of the pad 1 and the outer edge 11E (side edge) of the absorbent core 11. In this case, it is preferable that the area S1 of the non-existent region n11 in the overlapping region Ro is larger than the area S2 of the non-existent region n11 in the adjacent region Ra (S1>S2). For this reason, in the pad 1 of this embodiment, the outer shape of the pad 1 and the outer shape of the absorbent core 11 (particularly the shape at the constricted portion Dc) are made different.

[0084] The fact that the area S1 of the non-existent region n11 is large in the overlap region Ro means that the outer edge 1E of the pad 1 protrudes outward in the width direction, while the protrusion of the outer edge 11E of the absorbent core 11 is suppressed. In addition, the outer shape of the pad 1 is more visible to the user than the outer shape of the absorbent core 11, and is more likely to be noticed by the user. Therefore, the protrusion (extension part E) of the outer edge 1E of the pad 1 makes the width of the pad 1 longer and the outer area of ​​the pad 1 larger, which visually reduces the user's anxiety about leakage. On the other hand, the protrusion of the highly rigid absorbent core 11 is suppressed, thereby improving the fit of the absorbent core 11 to the wearer's crotch. In addition, even if the absorbent core 11 does not protrude, it is difficult for the user to notice it, so there is little risk of visually increasing the user's anxiety about leakage.

[0085] As described above, the outer edge 1E of the pad 1 has a non-extended portion NE that is constricted inward from the imaginary line VL, rearward of the extended portion E in the front-rear direction. In this case, as shown in FIG. 7, it is preferable that at least a part of the non-extended portion NE is located in the adjacent region Ra. By doing so, in the adjacent region Ra, an increase in the width of the outer edge 1E of the pad 1 that is suddenly widened in the overlap region Ro (extended portion E) is suppressed, and the fit of the pad 1 to the crotch of the wearer is ensured. At the same time, the projection of the outer edge 11E of the absorbent core 11 is made larger than the overlap region Ro so that the area S2 of the non-existence region n11 in the adjacent region Ra is smaller than the area S1 of the non-existence region n11 in the overlap region Ro, thereby preventing leakage of excreted liquid.

[0086] In addition, the absorbent core 11 has, in the crotch portion 1m, a core constricted portion 11c whose outer edge 11E is constricted inward in the width direction, and a core narrowest portion 11N in the core constricted portion 11c, which is the narrowest in the width direction of the absorbent core 11. In this case, it is preferable that the outer edge 11E of the absorbent core 11 does not extend outward from a second imaginary line VL2 connecting a rear end 11Nb of the core narrowest portion 11N in the front-rear direction and a rear end 11cb of the core constricted portion 11c in the front-rear direction.

[0087] Alternatively, the outer edge 11E of the absorbent core 11 has a core extension portion that extends outward from the second imaginary line VL2, and the length in the front-rear direction of the core extension portion is preferably shorter than the length in the front-rear direction of the extension portion E of the pad 1 (L4 in FIG. 7). In other words, it is preferable that the area enclosed by the outer edge 11E of the absorbent core 11 and the second imaginary line VL2 in the core extension portion is smaller than the area enclosed by the outer edge 1E of the pad 1 and the imaginary line VL in the extension portion E.

[0088] 7, the width of the absorbent core 11 gradually increases from the narrowest core part 11N toward the rear end 11cb of the constricted core part 11c. Therefore, the absorbent core 11 does not have a core extension part that extends outward beyond the second imaginary line VL2.

[0089] As a result, the width of the absorbent core 11 does not increase at a steep incline behind the narrowest core portion 11N, and the protrusion of the outer edge 11E of the absorbent core 11 can be reduced. This improves the fit of the absorbent core 11 around the wearer's crotch. In addition, the outer shape of the absorbent core 11 is less noticeable to the user than the outer shape of the pad 1. Therefore, even if there is no core extension or the length of the core extension in the front-to-rear direction is short, there is little risk of visually increasing the user's anxiety about leakage.

[0090] As described above, the non-existence region n11 of the absorbent core 11 is between the side edge along the front-rear direction of the pad 1 and the side edge along the front-rear direction of the absorbent core 11. As shown in FIG. 8, the widthwise length W1 of the non-existence region n11 is preferably maximum at the position of the outer end 1Ee in the widthwise direction of the extension part E (i.e., the outer end 1Ee in the widthwise direction of the outer edge 1E of the pad 1). By doing so, the outer edge 1E of the pad 1 protrudes more, visually reducing the user's anxiety about leakage. On the other hand, the width of the absorbent core 11 is shortened, improving the fit of the pad 1 around the crotch of the wearer.

[0091] However, the outer shape of the absorbent core 11 is not limited to the above. For example, the outer shape of the absorbent core 11 may be rectangular, or may be similar or substantially similar to the outer shape of the product of the pad 1, and the outer edge 11E of the absorbent core 11 may extend beyond the second imaginary line VL2. The absorbent core 11 may have an outer shape that is symmetrical in the width direction, or an outer shape that is asymmetrical. The narrowest core portion 11N may have a length in the front-rear direction.

[0092] FIG. 8 is an explanatory diagram of the leak-preventing wall 6. The pad 1 has a leak-preventing wall 6 that can stand up on the skin side at the side in the width direction. The leak-preventing wall 6 is formed by a side sheet 5 and a leak-preventing wall elastic member 7. The side sheet 5 is fixed to the top sheet 2 by an adhesive region A1 from one end to the other end along the front-rear direction, and both ends in the front-rear direction are fixed to the top sheet 2 by an adhesive region A2 on the inside of the adhesive region A1 in the width direction. Therefore, the part of the side sheet 5 inside the adhesive regions A1 and A2 stands up on the skin side as the leak-preventing wall 6 due to contraction of the leak-preventing wall elastic member 7. Therefore, the inside end in the width direction of the adhesive region A1 becomes the standing starting point 6s of the leak-preventing wall 6 in the width direction.

[0093] The core constricted portion 11c has a first core constricted portion 11c1 that is constricted inward in the width direction from the position of the rising starting point 6s of the leakage preventing wall portion 6. In this case, it is preferable that the length L5 in the front-rear direction of the first core constricted portion 11c1 is equal to or less than half the length L6 in the front-rear direction of the core constricted portion 11c (L5≦L6 / 2).

[0094] This allows the absorbent core 11 to support the rising starting points 6s of the leakage preventing walls 6 from below over a wide range in the front-to-rear direction of the core constricted portion 11c. Therefore, the leakage preventing walls 6 can stand stably on the highly rigid absorbent core 11. Even if body pressure is applied when wearing the garment, the rising starting points 6s of the leakage preventing walls 6 are unlikely to shift, and leakage of excreted fluid can be suppressed.

[0095] 1, the pad 1 preferably has a line 8 along the front-rear direction that is visible from the skin side of the pad 1. The line 8 may overlap with the center of the absorbent core 11 in the width direction in the thickness direction.

[0096] This allows the user (wearer, caregiver, etc.) to use the line 8 as a guide and place the pad 1 straight along the wearer's vertical direction. In other words, the front-to-back direction of the pad 1 can be aligned with the wearer's vertical direction. This allows the widthwise center of the absorbent core 11 to be abutted against the center of the wearer's crotch (excretory opening). This makes it difficult for the pad 1 to get caught on the wearer's thighs, improving the fit of the absorbent core 11 to the wearer's crotch. Furthermore, the absorbent core 11 can receive and absorb excreted liquid securely, preventing leakage of excreted liquid.

[0097] In this embodiment, hot melt adhesive colored in a color (e.g., blue) different from the color of the topsheet 2 (e.g., white) is applied along the front-to-rear direction to the center of the width of the non-skin side of the topsheet 2. By doing so, the lines 8 can be formed at a position overlapping with the center of the width of the absorbent core 11. In addition, since the colored hot melt adhesive does not come into direct contact with the wearer's skin, irritation to the wearer's skin can be prevented. In addition, the visibility of the lines 8 from the skin side of the pad 1 is improved.

[0098] However, the hot melt adhesive, ink, etc. for forming the line 8 may be applied to a material other than the topsheet 2, for example, the core wrap sheet 12 or the absorbent core 11. In addition, the length, width, and shape of the line 8 in the front-rear direction shown in FIG. 1 are merely examples and are not limited thereto. For example, the line 8 does not have to be a continuous straight line shape as long as it extends along the front-rear direction, and may be a wavy line, a dashed line, or the like. However, it is preferable that the line 8 is provided long from the front end to the rear end of the pad 1, as in the line 8 shown in FIG. 1. This makes it easier for the wearer to wear the pad 1 by using the line 8 as a marker.

[0099] The pad 1 has an outer shape in which the width is shorter at both front-rear end portions and the four corners 1C are narrowed. In the pad 1 shown in Fig. 3, the outer edges 1E of the corners 1C form arc shapes (e.g., arc shapes with a radius of 30 mm or less) that protrude inward in the width direction.

[0100] By doing so, the pad 1 can fit more easily to the wearer's rounded buttocks and lower abdomen than if the pad 1 were rectangular. Also, even if the width of both ends of the pad 1 in the front-to-back direction is short, the effect on leakage of excreted liquid is small. In other words, the length of the pad 1 in the front-to-back direction is increased to visually reduce the wearer's anxiety about leakage, while the width of the front and back ends, which have little effect on leakage, is shortened. By doing so, the planar area of ​​the pad 1 can be reduced, and the discomfort felt when worn can be reduced.

[0101] 2, the minimum widthwise length W2 from one end of the back sheet 3 in the widthwise direction to one end of the exterior sheet 4 in the widthwise direction is preferably 15 mm or more. Compared with the exterior sheet 4 made of nonwoven fabric or the like, the back sheet 3 made of a resin film or the like has higher rigidity. Therefore, by increasing the width (W2) of the low rigidity portion of only the exterior sheet 4, the outer width of the pad 1 can be increased while softening the contact of the side edges of the pad 1 with the wearer (thighs).

[0102] Although the embodiment of the present invention has been described above, the above embodiment is intended to facilitate understanding of the present invention and is not intended to limit the present invention. Furthermore, the present invention may be modified or improved without departing from the spirit of the present invention, and it goes without saying that the present invention includes equivalents thereof.
