Hereinafter, the absorbent article of the present invention will be described based on its preferred embodiment. 1 to 5 show a deployable disposable diaper (hereinafter, also simply referred to as a "diaper") which is an embodiment of the absorbent article of the present invention. FIG. 1 shows the configuration of the diaper 1 as viewed from the skin-facing surface side.
The diaper 1 shown in FIG. 1 corresponds to the front-back direction of the wearer in its unfolded and extended state, and is orthogonal to the vertical direction X extending from the ventral side of the wearer to the dorsal side through the crotch portion and the vertical direction X. It has a lateral direction Y to be used. The diaper 1 has a crotch portion C located between the ventral portion A and the dorsal portion B arranged on the ventral side of the wearer and the ventral portion A and the dorsal portion B when the diaper 1 is worn. I have. Each region A, B, and C is a region obtained by dividing the total length of the diaper 1 in the vertical direction X into three equal parts, and extends continuously in the front-rear direction of the wearer. The inseam C has an excretion portion facing portion (not shown) that is arranged to face the excretion portion of the wearer when the diaper 1 is worn.

As shown in FIG. 2, the diaper 1 includes a liquid-permeable surface sheet 2 that forms a skin-facing surface, and a liquid-impermeable (including water-repellent) leak-proof sheet 3 that forms a non-skin-facing surface. A liquid-retaining absorber 4 arranged between the surface sheet 2 and the leak-proof sheet 3 is provided, and these members constitute the absorbent main body 10.
The surface sheet 2 and the leak-proof sheet 3 each have a larger size than the absorber 4, and extend outward from the outer peripheral edge of the absorber 4. The surface sheet 2 and the leak-proof sheet 3 extend outward in the horizontal direction Y from both side edges of the absorber 4 along the vertical direction X. The edges of both ends of the surface sheet 2 and the leak-proof sheet 3 in the present embodiment substantially coincide with the edges of both ends of the diaper 1 in the longitudinal direction.

The diaper 1 includes a liquid-retaining absorber 4. The absorber 4 shown in FIG. 1 is arranged so that its longitudinal direction coincides with the vertical direction X of the diaper, and extends from the ventral side A to the dorsal side B via the inseam C. The both longitudinal edges of the absorber 4 are located inward of the longitudinal X bilateral edges of the diaper 1.
The absorber 4 is formed by coating an absorbent core 40 having an absorbent performance on a liquid-permeable core wrap sheet (not shown). The absorbent core 40 of the present embodiment has a shape in which the four corners of a substantially rectangular shape long in one direction are notched diagonally, and has a portion confined in the lateral direction Y in the inseam C.

In the present specification, the "expanded and stretched state" of the diaper 1 means that the diaper 1 is in the unfolded state, and the elastic member of each part of the unfolded diaper 1 is stretched to eliminate the influence of the elastic member. It means the state of being expanded until it becomes the same as the dimensions when it is expanded in a flat state.
Further, the "skin facing surface" is a surface facing the wearer's skin when wearing the diaper when focusing on the diaper or its constituent members (for example, an absorber), and the "non-skin facing surface" is the diaper. This is the surface that faces the wearer's skin when worn. That is, the skin-facing surface is the surface relatively close to the wearer's skin, and the non-skin-facing surface is the surface relatively far from the wearer's skin. "When worn" and "wearing state" refer to a state in which the proper wearing position of the diaper is maintained and worn.

In the diaper 1 of the present embodiment, as shown in FIG. 1, a pair of fastening tapes 7 and 7 are provided on both side edges of the waist flap portion WF of the dorsal portion B, which will be described later, along the vertical direction X. Each fastening tape 7 is arranged so as to extend from both side edges along the vertical direction X of the waist flap portion WF. One end of each fastening tape 7 on the inner side in the lateral direction is fixed between the sheet members constituting the diaper 1, for example, between the leak-proof sheet 3 and the exterior sheet (not shown).

The non-skin facing surface of the ventral side A of the diaper 1 is provided with a fastening region (not shown) to which the fastening portion provided on the fastening tape 7 can be detachably fastened. As the fastening region, an appropriate material is selected according to the material of the fastening portion included in the fastening tape 7. For example, when the fastening portion is a male material of a mechanical fastener, a fiber sheet that can engage with the male material, for example, a knitted fabric or a non-woven fabric, can be used as the female material of the mechanical fastener as the fastening region. When the fastening portion is an adhesive, for example, a smooth film made of synthetic resin can be used as the fastening region. For example, a sheet member such as an exterior sheet forming a non-skin facing surface on the ventral side A of the diaper 1 may be a fastening region.

The diaper 1 includes a pair of leakage-proof cuffs 6 and 6 arranged along both sides of the absorbent body 10 along the vertical direction X. The leak-proof cuff 6 of the present embodiment has an upright region F2 in the inseam C where the upright seat portion 65 stands up toward the wearer's skin side (see FIG. 1). In the upright region F2, the leakage-proof cuff 6 is in an upright state. The upright region F2 is located at least in the inseam C.
As shown in FIG. 2, the leak-proof cuff 6 is fixed on the absorbent main body 10 and is free on the wearer's skin side with the fixed portion 23 fixed to the absorbent main body 10 in the upright region F2 as a base end. Stand up to form an edge.
The leak-proof cuff 6 shown in FIG. 2 is not in an upright state because it is in the expanded and extended state of the diaper 1, but when the elastic member 61 for forming a cuff, which will be described later, is released from the extended state and contracted, the fixed portion is described. It stands upright with 23 as the base end. The base end on which the leakage-proof cuff 6 of the present embodiment stands is located on the lateral outer side of the absorber 4. Hereinafter, the fixing portion 23 forming the base end is also referred to as a “side fixing portion” 23.

The leak-proof cuff 6 is composed of a water-repellent and breathable cuff-forming sheet 16. In the leak-proof cuff 6, one or more thread-shaped elastic members 61 for forming a cuff are arranged at the end on the inner side in the lateral direction in an extended state in the vertical direction X. As the elastic member 61 for forming the cuff contracts, the leak-proof cuff 6 stands up at least at the inseam C, thereby suppressing the outflow of excrement such as urine to the outside in the lateral direction Y.

The diaper 1 of the present embodiment includes an exterior sheet (not shown) arranged on the non-skin facing surface side of the leak-proof sheet 3.
In the diaper 1 of the present embodiment, an exterior sheet is arranged on the non-skin facing surface side of the absorbent main body 10. The exterior sheet is a member that forms the outer surface of the diaper 1 that can be visually recognized from the outside when the diaper 1 is worn. The exterior sheet is arranged on the non-skin facing surface of the absorbent main body 10 extending from the ventral side A to the dorsal side B via the inseam C. Further, the exterior sheet forms the outer shape of the diaper 1 in the expanded and extended state, and the peripheral edge of the exterior sheet forms the contour lines of the ventral side portion A, the inseam portion C, and the dorsal side portion B, respectively.
In the contour of the diaper 1 of the present embodiment, the central side of the vertical direction X, that is, the portion on the inseam C side is constricted in the horizontal direction Y, and the end portion of the vertical direction X in each of the ventral side portion A and the dorsal side portion B. The side projects laterally Y outward from the portion of the inseam C side. In other words, the diaper 1 of the present embodiment has a wide portion in each of the ventral side portion A and the dorsal side portion B, and has a constricted portion narrower than the wide portion between these wide portions in the vertical direction X. is doing.

The exterior sheet extends outward in the lateral direction Y from both side edges along the vertical direction X of the absorber 4, and forms a side flap portion SF together with the cuff forming sheet 16 constituting the leakage-proof cuff 6. ..
The side flap portion SF is a portion made of a member extending outward in the horizontal direction Y from both side edges of the absorber 4 along the vertical direction X. In the present embodiment, the side flap portion SF includes a cuff forming sheet 16, a surface sheet 2, a leak-proof sheet 3, and an exterior sheet extending outward in the lateral direction Y from both side edges of the absorber 4. These sheets extend from the ventral side A to the dorsal side B via the inseam C, and extend laterally Y outward from each of both side edges of the absorber 4. These sheets are joined to each other by known joining means such as an adhesive, a heat seal, and an ultrasonic seal at the extending portions from both side edges of the absorber 4.

In the diaper 1 of the present embodiment, as shown in FIG. 1, the elastic members 31 for forming leg gathers are provided on both side portions of the diaper 1 along the vertical direction X, specifically, each of the pair of side flap portions SF and SF. Is arranged in an extended state so as to extend in the vertical direction X through the lower crotch C. Hereinafter, the elastic member 31 for forming leg gathers is also referred to as a leg elastic member. Due to the contraction of the leg elastic member 31, leg gathers are formed on the left and right portions arranged around the wearer's legs, that is, on both sides of the diaper 1 in the vertical direction X. In the present embodiment, the leg elastic member 31 is fixed between the cuff forming sheet 16 and the leak-proof sheet 3 in the side flap portion SF in an extended state along the vertical direction X.

The diaper 1 of the present embodiment is the peripheral edge of the absorber 4 on the end side of the dorsal side portion B in the vertical direction X, specifically, in the region between the front and rear ends of the wide portion of the dorsal side portion B in the vertical direction X. It has a waist flap portion WF extending outward from the vertical direction X or outward in the horizontal direction Y. The waist flap portion WF is a portion formed of a member extending outward in the vertical direction X or outward in the horizontal direction Y from the peripheral edge of the absorber 4 on the end side of the dorsal side portion B in the vertical direction X. .. In the present embodiment, the waist flap portion WF is composed of a cuff forming sheet 16, a surface sheet 2, a leakage-proof sheet 3, and an exterior sheet extending outward from the peripheral edge of the absorber 4. These sheets are joined to each other by known joining means such as an adhesive, a heat seal, and an ultrasonic seal at a portion extending from the peripheral edge of the absorber 4. The waist flap portion WF corresponds to the waist circumference of the wearer when the diaper 1 is worn. Both sides of the waist flap portion WF in the lateral direction Y are also front and rear ends of the side flap portion SF in the vertical direction X.

The configuration of the leakage-proof cuff 6 of the present embodiment will be described in detail. The leak-proof cuff 6 of the present embodiment is formed by folding one cuff-forming sheet 16 a plurality of times along a crease along the vertical direction X. In the present embodiment, since one cuff forming sheet 16 is folded back at two creases, the leak-proof cuff 6 is a folded portion where the cuff forming sheet 16 is folded back in a cross-sectional view along the lateral direction Y. It has two places. Of these two folded portions, the folded portion on the outer side of the lateral Y forms the free end of the leak-proof cuff 6, and the folded portion on the inner side of the lateral Y forms the inner end of the leak-proof cuff 6. ing.

The leak-proof cuff 6 of the present embodiment has a band-shaped skin contact portion 63 on the free end side (see FIG. 2). The skin contact portion 63 has a skin contact surface 12 that comes into contact with the wearer's skin in the wearing state (see FIG. 2). The skin contact portion 63 is arranged between the skin side sheet 13 forming the skin contact surface 12, the non-skin side sheet 14 on which the skin side sheet 13 faces, and the skin side sheet 13 and the non-skin side sheet 14. It is provided with an elastic member 61 for forming a cuff.
The non-skin side sheet 14 of the present embodiment is formed by folding one cuff forming sheet 16 continuous with the skin side sheet 13 along the vertical direction X.

2 and 3 are shown so that a gap is formed between the sheets forming the inner end of the leakage-proof cuff 6 in the lateral direction Y, but one cuff is provided so that no gap is formed between the sheets. The forming sheet 16 may be folded to form the leakage-proof cuff 6. In the leak-proof cuff 6 in the non-upright region F1 shown in FIG. 3, a slight gap may be generated because the skin-side sheet and the non-skin-side sheet are not joined as described later.

The leak-proof cuff 6 of the present embodiment has an upright sheet portion 65 located on the non-skin facing surface side of the skin contact portion 63 in the thickness direction Z of the diaper 1. The upright sheet portion 65 forms an upright portion of the leak-proof cuff, and stands up due to the contraction of the cuff forming elastic member 61 arranged on the skin contact portion 63. As shown in FIGS. 2 and 3, the upright sheet portion 65 is located between the skin contact portion 63 and the absorbent main body 10 in the thickness direction Z of the diaper 1.
The upright sheet portion 65 faces the skin contact portion 63 in the thickness direction Z of the diaper 1 and extends laterally from the leak-proof cuff 6 to the side sheet portion 17 and the side sheet portion 17 and the absorbent main body 10. It has a main body side seat portion 18 located between and. The side seat portion 17 and the main body side seat portion 18 of the present embodiment are opposed to each other in the thickness direction Z of the diaper 1, and the cuff forming fixing portion 62 formed between the two seat portions 17 and 18 is interposed. It is joined.
The cuff forming fixing portion 62 is a fixing portion forming the upright sheet portion 65, and is continuously formed over the entire length of the leakage-proof cuff 6 in the vertical direction X. The form of the "cuff forming and fixing portion 62 continuously formed over the entire length in the vertical direction X" includes a form in which the cuff forming and fixing portion 62 continuously extends in the vertical direction X, and also cuff forming and fixing. A form in which the portions 62 are composed of a plurality of small fixing portions a, the small fixing portions a partially overlap each other, and the small fixing portions a are intermittently arranged so as to be continuous with the vertical X total length of the leakage-proof cuff 6. Is included (see FIG. 8). For example, in the cuff forming fixing portion 62 shown in FIG. 8, each small fixing portion a forming the cuff forming fixing portion 62 is tilted in both the vertical direction X and the horizontal direction Y, and the small fixing portions adjacent to each other in the vertical direction X are fixed. A part of the part a is arranged so as to overlap each other at the same position in the vertical direction X.

The leak-proof cuff 6 of the present embodiment has a non-standing region F1 on both the ventral side A and the dorsal side B. The leakage-proof cuff 6 of the present embodiment has non-standing regions F1 on both sides of the standing region F2 in the vertical direction X. Alternatively, the leak-proof cuff 6 may have a non-standing region F1 on at least one of the ventral portion A and the dorsal portion B.

The non-standing region F1 is a region in which the elastic member 61 for forming a cuff is not arranged in the vertical direction X, or a region in which the elastic member 61 for forming a cuff is arranged so as not to exhibit elastic elasticity. In the latter region, the elastic member 61 for forming a cuff is made so as not to exhibit elastic elasticity by being subjected to a treatment such as cutting or by not being joined to the sheet 16 for forming a cuff in an extended state. ing.
In the non-upright region F1, as shown in FIG. 3, the upright sheet portion 65 is fixed on the absorbent main body 10 via the fixing portion 67, and the skin contact portion 63 is fixed to the upright sheet portion via the other fixing portion 60. It is fixed to the portion 65. Hereinafter, the fixing portion 60 for fixing the skin contact portion 63 and the upright seat portion 65 is referred to as a "fixing portion in the cuff" 60, and the fixing portion 67 for fixing the upright seat portion 65 and the absorbent main body 10 is referred to as a "main body". Also referred to as "side fixing portion" 67.
In the non-upright region F1 of the present embodiment, the main body side sheet portion 18 in the upright sheet portion 65 is fixed on the surface sheet 2 in the absorbent main body 10 via the main body side fixing portion 67.

In the skin contact portion 63 of the non-standing region F1, the skin side sheet 13 and the non-skin side sheet 14 are not joined. That is, in the non-standing region F1, the skin-side sheet 13 and the non-skin-side sheet 14 are not joined.
In the non-standing region F1, the in-cuff fixing portion 60 is located at a portion other than both ends of the skin contact portion 63 in the lateral direction Y. That is, the skin contact portion 63 and the upright sheet portion 65 are not joined at both ends of the skin contact portion 63 in the lateral direction Y.
In the non-standing region F1, the elastic member 61 for forming a cuff does not exhibit shrinkage, and the standing sheet portion 65 is fixed to the absorbent body 10 by the fixing portion 60 in the cuff, so that the standing sheet portion 65 does not stand. It is done like this.

Since the non-standing region F1 in the ventral portion A or the dorsal portion B is a region around the waist of the wearer in the wearing state, the region is between the region and the wearer's skin according to the movement of the wearer. Is prone to friction. Excessive friction can cause skin irritation.
In the skin contact portion 63 in the non-standing region F1 of the present embodiment, as shown in FIG. 3, the skin side sheet 13 and the non-skin side sheet 14 are non-bonded. On the other hand, the skin contact portion 63 and the upright sheet portion 65 are fixed via the fixing portion 60 in the cuff. With such a configuration, in the non-upright region F1, the positions of the skin-side sheet 13 and the non-skin-side sheet 14 can be displaced in the lateral direction Y while maintaining the skin contact surface 12 well (). See Figure 4). That is, since the skin-side sheet 13 has room to move in the lateral direction Y, the skin contact portion 63 satisfactorily follows the movement of the wearer's skin, and friction is unlikely to occur. In particular, when the in-cuff fixing portion 60 is located at a portion other than both ends of the skin contact portion 63 in the lateral direction Y, the in-cuff fixing portion 60 is the starting point with the skin contact surface 12 in contact with the skin. The present inventors have found that the skin-side sheet 13 becomes easier to move. Moreover, since the in-cuff fixing portion 60 is located between the skin contact portion 63 and the upright sheet portion 65, the feel of the in-cuff fixing portion 60, which is a joint portion between the sheets, is not easily transmitted to the skin, so that a good touch can be obtained. In this way, in the diaper 1 of the present embodiment, excessive friction between the leak-proof cuff 6 and the skin can be effectively suppressed, and an excellent touch can be obtained.

The in-cuff fixing portion 60 is a joint portion for joining the non-skin side sheet 14 of the skin contact portion 63 and the side sheet portion 17 of the upright seat portion 65. The fixing portion 60 in the cuff can be formed by a known joining means such as an adhesive, a heat seal, and an ultrasonic seal.
The cuff forming fixing portion 62, the main body side fixing portion 67 and the side fixing portion 23 can also be formed by the above-mentioned known joining means.

From the viewpoint of further improving the followability of the skin-side sheet 13 to the skin in the non-standing region F1, the length W2 (see FIG. 3) of the in-cuff fixing portion 60 in the lateral direction Y is the skin contact surface in the lateral direction Y. It is preferably 10% or more, more preferably 20% or more, preferably 50% or less, more preferably 40% or less, and preferably 10% or more with respect to the length W1 (see FIG. 3) of 12. It is 50% or less, more preferably 20% or more and 40% or less.
From the same viewpoint as above, the length W1 (see FIG. 3) of the skin contact surface 12 in the lateral direction Y is preferably 6 mm or more, more preferably 12 mm or more, and preferably 25 mm or less, more preferably 18 mm. It is less than or equal to, preferably 6 mm or more and 25 mm or less, and more preferably 12 mm or more and 18 mm or less.
From the viewpoint of further improving the shape retention of the skin contact portion 63, the length W2 (see FIG. 3) of the in-cuff fixing portion 60 in the lateral direction Y is preferably 2 mm or more, more preferably 3 mm or more, and more preferably. Is 8 mm or less, more preferably 6 mm or less, preferably 2 mm or more and 8 mm or less, and more preferably 3 mm or more and 6 mm or less.

From the viewpoint of further suppressing friction with the skin-side sheet 13 in the non-standing region F1, in the non-standing region F1, the distance D1 between the in-cuff fixing portion 60 and the edge of the skin contact portion 63 in the lateral direction Y (FIG. 3) is preferably 10% or more, more preferably 20% or more, and preferably 50% or less, more preferably, with respect to the length W1 (see FIG. 3) of the skin contact surface 12 in the lateral direction Y. Is 40% or less, preferably 10% or more and 50% or less, and more preferably 20% or more and 40% or less.
From the same viewpoint as above, the distance D1 (see FIG. 3) between the in-cuff fixing portion 60 and the edge of the skin contact portion 63 in the lateral direction Y is preferably 2 mm or more, more preferably 3 mm or more. Further, it is preferably 8 mm or less, more preferably 6 mm or less, preferably 2 mm or more and 8 mm or less, and more preferably 3 mm or more and 6 mm or less.

The distance D1 between the cuff internal fixation portion 60 and both end edges of the skin contact portion 63 in the lateral direction Y may be the same or different. In the present embodiment, the distance between the in-cuff fixing portion 60 in the lateral direction Y and the end edge on the inward side of the same direction Y of the skin contact portion 63 is the distance between the in-cuff fixing portion 60 and the skin contact portion 63 in the lateral direction Y. Is different from the distance between the same direction and the outer edge of Y.

From the viewpoint of further suppressing friction with the skin side sheet 13 in the non-standing region F1, the length of the non-standing region F1 in the vertical direction X is preferably 5% or more with respect to the total length of the leakage-proof cuff 6 in the vertical direction X. , More preferably 10% or more, preferably 30% or less, more preferably 20% or less, and preferably 5% or more and 30% or less, more preferably 10% or more and 20% or less.

The non-standing region F1 easily comes into contact with the wearer's skin in a portion where the thickness of the diaper 1 is larger than that of the other portions. From the viewpoint of more reliably obtaining the above-mentioned good touch in the portion that easily comes into contact with the wearer's skin, the leak-proof cuff 6 preferably has a non-standing region F1 at a position overlapping with the absorber 4. In this case, the entire non-standing region F1 does not have to overlap with the absorber 4, and may partially overlap with the absorber 4.

In the leak-proof cuff 6 of the present embodiment, the skin contact portion 63 and the upright sheet portion 65 are formed by folding one cuff-forming sheet at a plurality of locations along the vertical direction. In the cross-sectional view of the leak-proof cuff 6 along the lateral direction Y, the skin contact portion 63 and the upright sheet portion 65 are connected via the folded portion of the cuff forming sheet 16 on the inner side in the lateral direction Y (FIG. 2). In other words, the leak-proof cuff 6 of the present embodiment has a folded-back portion in which the cuff forming sheet 16 is continuously folded outward in the lateral direction Y in a cross-sectional view along the lateral direction Y. .. The folded portion is a lateral Y inner end of the skin contact portion 63 and a lateral Y inner end of the upright sheet portion 65. As described above, in the cross-sectional view, the cuff forming sheet 16 is folded back so as to be continuous on the outer side in the lateral direction Y, and the structure of the leak-proof cuff forming the skin contact portion 63 is hereinafter referred to as "outer folding structure".
