BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described based on its preferred embodiments with reference to the drawings. In addition, in the following description of the drawings, the same or similar reference numerals are given to the same or similar parts. The drawings are basically schematic, and the ratio of each dimension may differ from the actual one.

1 to 4 show a holder 1, which is one embodiment of the holder of the present invention. 5 and 6 show a disposable diaper 10 (hereinafter also referred to as "diaper 10") including a holder 1 and an absorbent pad 11 secured thereto as an example of use of the holder of the present invention. It is shown. The diaper 10 is one embodiment of the absorbent article of the present invention, that is, an absorbent article comprising the holder of the present invention and an absorbent pad attachable to the holder. As shown in FIG. 5, the diaper 10 is constructed by connecting the holder 1 and the absorbent pad 11 via the holder-side fastening structure 6 and the pad-side fastening structure 16. WH and a pair of leg openings LH, LH defined by the lower end in the height direction HD of the holder 1 and both side edges along the longitudinal direction (longitudinal direction X described later) of the absorbent pad 11. . Note that the absorbent pad 11 is not a constituent member of the holder 1 .

In the diaper 10, which is a separate type absorbent article, the holder 1 and the absorbent pad 11 can be freely connected and separated via the fixing structures 6, 16, so compared to conventional non-separate type absorbent articles, The load on the environment is reduced. That is, a conventional non-separate type absorbent article is used in which the portion corresponding to the waist of the wearer (portion corresponding to the holder) and the portion corresponding to the crotch portion of the wearer (portion corresponding to the absorbent pad) are inseparably integrated. When discarding later, even if the portion corresponding to the holder is not soiled, it has to be discarded together with the portion corresponding to the absorbent pad that is soiled with excrement. Since only the pad 11 needs to be replaced with a new one, the amount of garbage disposal and carbon dioxide emissions are reduced compared to non-separate type absorbent articles, and the burden on the environment can be reduced.
In addition, since the absorbent pad 11 is detachably fixed to the holder 1 while the diaper 10 is being worn, the work of replacing the absorbent pad 11 with a new one is simple, and the diaper 10 is similar to the conventional non-separate type. The burden of replacement work is greatly reduced compared to other absorbent articles.

The holder 1 is worn in a ring shape around the wearer's waist, and holds the absorbent pad 11 in a state in which it is worn by the wearer. and a circumferential direction CD along the waist circumference direction. The holder 1 is provided with a holder-side fastening structure 6 capable of detachably fastening the end region of the absorbent pad 11 . The end regions of the absorbent pad 11 are regions located at both ends when the total length of the absorbent pad 11 in the longitudinal direction X is divided into four equal parts, preferably into five equal parts.

Here, the absorbent pad 11 will be briefly described with reference to FIGS. It includes a liquid-impermeable, liquid-impermeable or water-repellent backsheet 13 positioned relatively far from the wearer's skin, and an absorbent body 14 interposed between the two sheets 12 and 13 . These members constituting the absorbent pad 11 are integrated by a known bonding means such as an adhesive. The absorbent pad 11 has a shape elongated in one direction in a plan view, and when the absorbent pad 11 is used, the longitudinal direction of the absorbent pad 11 is aligned with the height direction HD of the holder 1 pre-attached to the wearer. Let The longitudinal direction of the absorbent pad 11 corresponds to the longitudinal direction X corresponding to the front-rear direction of the wearer of the diaper 10 , and the lateral direction Y of the absorbent pad 11 orthogonal to the longitudinal direction X corresponds to the circumferential direction CD of the holder 1 . handle. On both sides of the absorbent pad 11 along the longitudinal direction X, there are arranged a pair of leak-proof cuffs 15, 15 that stand up against the wearer's skin when the diaper 10 is worn. Each leak-preventing cuff 15 includes a leak-preventing cuff-forming sheet 150 forming the main body of the leak-preventing cuff 15, and an elastic member 151 fixed to the sheet 150 in an elongated state in the longitudinal direction X. As shown in FIG. Pad-side fastening structures 16 are arranged on the skin-facing surfaces of both end regions of the absorbent pad 11 in the longitudinal direction X, and the pad-side fastening structures 16 are fastened to the holder-side fastening structures 6 of the holder 1 . By attaching the absorbent pad 11 to the holder 1, the absorbent pad 11 can be attached to the holder 1 in a detachable manner.
Note that the absorbent pad 11 is merely one embodiment of an absorbent pad to which the holder of the present invention can be applied. It is not limited to the absorbent pad 11 as long as it has a pad-side fastening structure that can be worn.

As used herein, the term “skin-facing surface” refers to a wearing article such as an absorbent article, a holder, or an absorbent pad, or a constituent member thereof (for example, a holder-side fastening structure of a holder), which is worn by the wearer when the wearing article is worn. The "non-skin facing surface" refers to the surface of the wearing article or its constituent members that faces away from the skin when the wearing article is worn.

The holder 1 will be described in detail below.
The holder 1 has an abdominal portion F arranged on the wearer's ventral side (front side) and a dorsal portion R arranged on the wearer's dorsal side (rear side), and constitutes the main body of the holder 1. A holder main body 2 is provided. The holder main body 2 forms the outer shape (outline) of the holder 1 in plan view, and the upper end 1a and the lower end 1b of the holder 1 in the height direction HD are the upper end and the lower end of the holder main body 2 . The holder 1 has a holder body portion 2 and a holder-side fastening structure 6 . The holder-side fastening structure 6 is fixed to the holder body portion 2 .

In this embodiment, the holder 1 (holder main body 2) has an annular shape as shown in FIG. 1, and has a waist opening WH into which a wearer's trunk is inserted when worn. Specifically, in the holder 1 of the present embodiment, the holder body portions 2 of the ventral portion F and the dorsal portion R are bonded to each other at both ends in the longitudinal direction along the circumferential direction CD of the holder 1 with an adhesive or a melt. A pair of body joints S, S are formed by being joined to each other by a known joining means such as wearing, and the ventral part F and the dorsal part R are connected via the pair of body joints S, S. and form a ring. The body joint portion S corresponds to a side seal portion in a general non-separate pants-type disposable diaper.

In this embodiment, the holder 1 (holder main body 2) has a rectangular shape in plan view in the maximum stretched state as shown in FIG. It is a straight line parallel to the direction of
Further, in this embodiment, the ventral portion F and the dorsal portion R have the same shape and the same size in a plan view, and the ventral portion F and the dorsal portion R are attached to each other while maintaining the main body joint portion S without breaking it. Their contours coincide when the sides R are superimposed.

As used herein, the term "maximum stretched state" refers to a state in which the elastic member of each part of the wearing article such as the absorbent article, holder, and absorbent pad is stretched to the maximum, and the design dimensions, that is, the state in which the influence of the elastic member is completely eliminated. It refers to the state in which it is expanded until it becomes the same size as when it is expanded flat.
In addition, the “unfolded and maximum stretched state” refers to a state in which the wearing article is spread flatly to be in the stretched state and then put into the maximum stretched state. In the case of an absorbent article having a seal portion, the absorbent article is separated at the side seal portion and spread flat to form the unfolded state.

In this embodiment, the holder main body 2 includes an outer layer sheet 3 forming the non-skin facing surface (outer surface) of the holder 1 and an inner layer sheet 4 forming the skin facing surface (inner surface) of the holder 1 . The inner layer sheet 4 can come into contact with the wearer's skin when the holder 1 is worn.

In this embodiment, as shown in FIG. 4, the outer layer sheet 3 is folded back at the upper end portion in the height direction HD toward the skin facing surface side, and the upper end 1a of the holder 1 is positioned at the folded fold of the outer layer sheet 3. The vicinity of the upper end 1a of the holder 1 (upper end portion) includes a laminated structure of the outer layer sheet 3 and its folded portion 30 . The folded portion 30 and the outer layer sheet 3 facing it are joined together by a known joining means such as an adhesive or fusion.

Moreover, the holder main body part 2 has elasticity in the circumferential direction CD. In this embodiment, the holder 1 (holder main body 2) includes an elastic member 5 that is arranged to be stretchable in a direction (circumferential direction CD) perpendicular to the height direction HD. More specifically, as shown in FIG. 4, between the outer layer sheet 3 and the inner layer sheet 4, and between the outer layer sheet 3 and its folded portion 30, a plurality of elastic members 5 are arranged perpendicular to the height direction HD. It is arrange|positioned so that expansion-contraction is possible in the direction (circumferential direction CD). As shown in FIG. 1, the plurality of elastic members 5 extend over the entire length of a direction (circumferential direction CD) orthogonal to the height direction HD of each of the ventral portion F and the dorsal portion R, and extend in the height direction HD. intermittently arranged. Each elastic member 5 is fixed to other peripheral members with an adhesive. The number and positions of the elastic members 5 to be arranged are not particularly limited, and can be appropriately set in consideration of the fit of the holder 1 to the wearer's body.

As both sheets 3 and 4, non-woven fabric, woven fabric, resin film, etc. by various production methods can be used, respectively. Specific examples of nonwoven fabrics that can be used as the sheets 3 and 4 include spunbond nonwoven fabrics, air-through nonwoven fabrics, and needle-punched nonwoven fabrics, and may have a single-layer structure or a laminated structure in which one or more types of nonwoven fabrics are laminated. .
Both sheets 3 and 4 may be of the same type or of different types. The term "same type" as used herein means that the manufacturing process, the type of constituent fibers, the fiber diameter and length of the constituent fibers, the thickness and basis weight of the fiber sheets are all the same among the sheets to be compared. If any one of these is different, then the contrasting sheets are "dissimilar" to each other.

Since the holder 1 does not include an absorber that absorbs and retains moisture, if washable materials are used as the constituent members of the holder main body 2 including the sheets 3 and 4, they can be washed and used repeatedly. can be possible. The fact that the holder 1 is washable leads to a reduction in the amount of garbage disposal and carbon dioxide emissions, and can contribute to a reduction in the burden on the environment. From the viewpoint of making the holder 1 washable, it is preferable that the members constituting the holder main body 2, such as the sheets 3 and 4, are made of woven fabric.

One or both of the sheets 3 and 4 may have stretchability in a direction (circumferential direction CD) perpendicular to the height direction HD. The holder of the present invention includes a form that does not have the elastic member 5 described above. It is preferably made of elastic nonwoven fabric. The present invention includes, for example, a form in which the outer layer sheet 3 has stretchability in a direction orthogonal to the height direction HD and the inner layer sheet 4 does not have stretchability.

Examples of stretchable nonwoven fabrics that can be used as both sheets 3 and 4 include nonwoven fabrics containing elastic filaments (hereinafter also referred to as "specific stretchable nonwoven fabrics"). The “elasticity” referred to here means that when the force is released from a state that can be stretched and is stretched 100% with respect to the original length (becomes 200% of the original length), the original The property of returning to a length of 125% or less of the length of In the specific stretchable nonwoven fabric, it is preferable that the elastic filaments are bonded to the nonwoven fabric in a substantially unstretched state. The nonwoven fabric preferably contains inelastic fibers.

In the specific stretchable nonwoven fabric, the elastic filaments are typically substantially continuous over the entire length in the extending direction of the elastic filaments in the specific stretchable nonwoven fabric. Also, the elastic filaments contain an elastic resin.
In the specific stretchable nonwoven fabric, the nonwoven fabric can be stretched in the same direction as the direction in which the elastic filaments extend. The term "stretchable" here refers to (a) the case where the constituent fibers of the nonwoven fabric themselves are stretched, and (b) even if the constituent fibers of the nonwoven fabric themselves are not stretched, the fibers bonded at the intersections are separated from each other. , Including the case where the three-dimensional structure formed by multiple fibers is structurally changed due to the bonding of fibers, etc., the constituent fibers are torn, and the slack of the fibers is stretched, so that the nonwoven fabric as a whole stretches. do. In the specific stretchable nonwoven fabric, the nonwoven fabric may already be stretchable in a raw fabric state before being joined to the elastic filaments. Alternatively, the raw fabric may not be extensible before being joined to the elastic filaments, but may be made extensible after being joined to the elastic filaments by being processed so as to be extensible. . Specific methods for making the nonwoven fabric stretchable include heat treatment, stretching between rolls, bite stretching by tooth grooves or gears, tensile stretching by a tenter, and the like.

A preferred embodiment of the specific stretchable nonwoven fabric includes one having a structure in which a plurality of elastic filaments are arranged between two nonwoven fabrics arranged opposite to each other. In such a preferred embodiment, the plurality of elastic filaments are arranged so as to extend in one direction (for example, a direction perpendicular to the height direction HD) without crossing each other, and intermittently in a direction perpendicular to the one direction. may be arranged, in which case the one direction may be the stretch direction of the specific stretchable nonwoven fabric. The two nonwoven fabrics may be of the same type or of different types. The term "same type" as used herein means that the manufacturing process, the type of constituent fibers, the fiber diameter and fiber length of the constituent fibers, the thickness and basis weight of the nonwoven fabric are all the same between the two nonwoven fabrics to be compared. . Two nonwovens are dissimilar to each other if at least one of these factors differs between the two nonwovens being contrasted.

As the stretchable nonwoven fabric that can be used as both sheets 3 and 4, various known ones can be used. A stretchable sheet, a stretchable nonwoven fabric produced by the method for producing a stretchable nonwoven fabric described in the same publication, a laminated sheet described in JP-A-10-29259, and the like can also be used.

The holder-side fastening structure 6, which is one of the features of the holder 1, is provided on at least one of the skin-facing surface and the non-skin-facing surface of the holder main body 2. there is In this embodiment, as shown in FIG. It is fixed on the facing surface. The holder-side fastening structure 6 is arranged on both the ventral side F and the dorsal side R, as shown in FIG. Note that the holder-side fastening structure 6 may be arranged only on one of the ventral portion F and the dorsal portion R.

As the holder-side fastening structure 6, it is sufficient that the pad-side fastening structure 16 (see FIG. 6) of the absorbent pad 11 can be detachably fastened. Can be used without restrictions. For example, one or both of the holder-side fastening structure 6 and the pad-side fastening structure 16 has an adhesive portion formed by applying an adhesive, and the pad-side fastening structure 16 is attached to the holder side via the adhesive portion. It may be detachably attached to the fastening structure 6 .

In this embodiment, a mechanical hook-and-loop fastener is used as the fastening structure including the holder-side fastening structure 6 and the pad-side fastening structure 16 . The term "mechanical hook-and-loop fastener" as used here means a surface member (male member) with hook material (engagement member) consisting of hook-shaped projections arranged on one side, and a loop material consisting of pile-shaped projections on one side. An arranged face member (female member) refers to a set of fasteners. A specific example of the mechanical hook-and-loop fastener is Velcro (registered trademark).
Specifically, in this embodiment, the holder-side fastening structure 6 is a female member of a mechanical hook-and-loop fastener, and is provided on the base material and the non-skin facing surface (outer surface) of the base material. A structure 16 includes a secureable attachment area. The base material included in the holder-side fastening structure 6 is directly fixed to the holder main body 2 at a joint portion 8 which will be described later. The pad-side fastening structure 16 is a male member of a mechanical hook-and-loop fastener. have.

As one of the main features of the holder 1, as shown in FIGS. 1 to 3, the holder-side fastening structure 6 has a plurality of joints formed intermittently in the circumferential direction CD with respect to the holder main body 2. 8 are joined together. As a result, when the holder main body 2 contracts in the circumferential direction CD, the convex portion protrudes toward the non-skin-facing surface side of the holder-side fastening structure 6 between the joint portions 8 adjacent in the circumferential direction CD. 9 is formed. When the wearer wears the holder 1 around the waist, the holder 1 shrinks in the circumferential direction CD to form the projections 9 . By forming the projections 9 on the holder-side fastening structure 6, the holder-side fastening structure 6 has improved cushioning properties against external force applied from the non-skin facing side. In this embodiment, in order to attach the absorbent pad 11 to the holder 1 worn around the wearer's waist, when the end region of the absorbent pad 11 is pressed against the holder-side fastening structure 6, the holder side Since the fastening structure 6 acts as a cushion, it is possible to reduce discomfort, such as a feeling of oppression and discomfort caused by pressing around the waist, and prevent the wearer from feeling discomfort.
From the viewpoint of ensuring that the protrusions 9 are formed on the holder-side fastening structure 6, the holder-side fastening structure 6 is joined to the holder main body 2 in a state of being stretched in the circumferential direction CD. preferably.

In a state in which the holder 1 is worn around the wearer's waist, the wearer can easily press the absorbent pad 11 against the holder-side fastening structure 6 on the central region 2C of the ventral portion F, thereby facilitating the attachment operation. be able to. Further, when attaching the absorbent pad 11 to the holder 1, the absorbent pad 11 can be strongly pressed against the central region 2C of the ventral portion F of the holder main body 2. FIG. Therefore, it is preferable that the central region 2C of the ventral portion F of the holder body portion 2 has improved cushioning properties from the viewpoint that effects such as a reduction in pressure on the abdomen can be expected. From this point of view, it is preferable that the holder-side fastening structure 6 and the holder main body 2 are joined at least at a central region 2</b>C of the holder main body 2 in the circumferential direction CD at a plurality of joints 8 . For example, as shown in FIG. 2, central regions 2C of the ventral side F and the dorsal side R of the holder main body 2 surround the holder 1 with the ventral side F and the dorsal side R overlapping each other. When the holder main body 2 is divided into 5 equal parts in the direction CD in a state of being stretched to the maximum in the direction along the direction CD, the area can be made up of the central three parts.

In the present embodiment, as described above, the joints 8 are intermittently formed in the circumferential direction CD of the holder main body 2. Between the joints 8, 8 adjacent to each other in the circumferential direction CD, the holder side A non-joint portion 81 is formed where the fastening structure 6 is not joined to the holder main body portion 2 . When the holder main body 2 contracts in the circumferential direction CD, that is, when the holder 1 is in a non-expanded state, the holder-side fastening structure 6 protrudes from the non-bonded portion 81 to form the convex portion 9 . The non-joint portion 81 may be intermittently formed in the height direction HD of the holder 1, but as shown in FIGS. 1 to 3, it is formed continuously in the height direction HD of the holder 1. is preferred. In the present embodiment, joint portions 8 intermittently formed in the circumferential direction CD extend along the height direction HD and are formed between joint portions 8, 8 adjacent to each other in the circumferential direction CD. The non-bonded portion 81 also extends along the height direction HD. Since the non-joint portion 81 is formed continuously in the height direction HD, the convex portion 9 is formed continuously extending in the height direction when the holder 1 is in the non-stretched state. The advantages of forming the projections 9 continuously in the height direction HD are as follows.

When the absorbent pad 11 is attached to the holder 1 worn around the waist of the wearer, the absorbent pad 11 is pulled downward in the vertical direction by gravity. A vertical shear force is applied to the structure 16 . In the mounting state of the holder 1 , the vertical direction matches the height direction HD of the holder 1 .
In this embodiment, when the absorbent pad 11 is attached to the holder 1, the pad-side fastening structure 16 is fastened to the protrusion 9 of the holder-side fastening structure 6, as shown in FIG. Since the protrusions 9 are formed continuously in the height direction HD, the direction in which the absorbent pad 11 attached to the holder 1 is pulled by gravity, that is, the shear direction S1 between the fastening structures 6 and 16 , and the direction in which the projection 9 extends. By aligning the shearing direction S1 with the direction in which the projections 9 extend, even when the absorbent pad 11 is pulled vertically downward by gravity and a shearing force is applied between the fastening structures 6 and 16, Even if there is, the convex portion 9 can be made difficult to be crushed. Since the convex portion 9 is hard to be crushed, even if a shearing force is applied between the two fastening structures 6 and 16, the pad-side fastening structure 16 is kept fastened to the holder-side fastening structure 6. Therefore, the absorbent pad 11 is less likely to come off from the holder 1 while the diaper 10 is in use. For example, even when the absorbent pad 11 absorbs excrement during use of the diaper 1 and the weight of the absorbent pad 11 increases, the pad-side fastening structure 16 may not be fastened to the holder-side fastening structure 6 . Since it is easier to maintain, the absorbent pad 11 is less likely to come off from the holder 1 while the diaper 10 is in use.

Conventionally, as in Patent Documents 3 and 4, vertical folds along the longitudinal direction of the absorbent article have been formed on the landing tape. When fastening, the fastening tape is pulled from the outside in the width direction of the absorbent article toward the inside. Therefore, the shearing direction between the fastening tape and the landing tape intersects the direction in which the longitudinal pleats formed in the landing tape extend.
In order to withstand the shearing force in the height direction HD in the separate type absorbent article having the holder-side fastening structure 6 that is not required to withstand the shearing force in the circumferential direction CD, such as the diaper 10, Forming the projections 9 extending in the height direction HD on the holder-side fastening structure 6 is a new discovery made by the present inventors.

Further, in Patent Documents 3 and 4, as described above, the fastening tape is attached while being pulled from the outside in the width direction of the absorbent article toward the inside. The direction of the external force applied to the vertical folds of the landing tape when worn and the direction in which the vertical folds extend are substantially perpendicular to each other when the landing tape is viewed from above. In other words, an external force is applied from the outside to the inside in the width direction to the longitudinal folds extending along the longitudinal direction. Therefore, there is a possibility that the vertical folds may collapse inward in the width direction. When the longitudinal folds of the landing tape collapse, the landing tape does not act as a cushion easily.
In this embodiment, the projections 9 extend along the height direction HD. is substantially parallel to the extending direction of the holder-side fastening structure 6 in a plan view. Therefore, external force in the circumferential direction CD is less likely to be applied to the convex portion 9 extending along the height direction HD, and the convex portion 9 is less likely to collapse. It is easy to prevent the feeling of discomfort.

The joint portion 8 may be formed by applying an adhesive to either one or both of the holder side fastening structure 6 and the holder body portion 2, or may be formed by bonding the holder side fastening structure 6 and the holder body portion 2 together. It may be a fused portion that is fused by heat, ultrasonic waves, or the like. From the viewpoint of ease of control of the shape of the joint 8, the formation position, etc., the joint 8 is preferably a fusion-bonded portion.

Only one projection 9 may be formed, but from the viewpoint of dispersing the shearing force applied between the holder-side fastening structure 6 and the pad-side fastening structure 16 and making the projection 9 more difficult to crush. , is preferably formed in plurality. From the same point of view, the cross-sectional shape of the protrusion 9 along the circumferential direction CD is preferably a curved shape that protrudes toward the side opposite to the holder main body 2, as shown in FIG. preferably in the form of

In the circumferential direction CD, the length D1 between the adjacent joints 8, 8 is preferably longer than the length L1 of the joints 8 (see FIG. 2). By doing so, the shape of the convex portion 9 formed between the joint portions 8, 8 can be stabilized, and the cushioning property of the holder-side fastening structure 6 can be further improved. From the viewpoint of achieving this effect more remarkably, the ratio D1/L1 of the length D1 to the length L1 is preferably 1.1 or more, more preferably 1.5 or more, and still more preferably 2. .0 or more. From the viewpoint of facilitating the formation of the projections 9, the ratio D1/L1 of the length D1 to the length L1 is preferably 20 or less, more preferably 15 or less, and even more preferably 10 or less. From the viewpoint of achieving both these viewpoints, the ratio D1/L1 of the length D1 to the length L1 is preferably 1.1 or more and 20 or less, more preferably 1.5 or more and 15 or less, and still more preferably 2.0. 10 or less. The length L1 of the joint portion 8 can be the length of the longer joint portion 8 among the joint portions 8 adjacent in the circumferential direction CD.

7 to 10 exemplify layout patterns of the joints 8 that can be employed in the present invention. Regarding the embodiment of the holder to be described later, the configuration different from that of the holder 1 described above will be mainly described, and the configuration similar to that of the holder 1 will be given the same reference numerals, and the description thereof will be omitted. The description of the holder 1 is appropriately applied to configurations that are not particularly described in the embodiment of the holder described later.

The holder 1A shown in FIG. 7 has a plurality of non-joint portions 81, and differs from the holder 1 shown in FIGS. 1 to 3 in that the length D1 of the circumferential direction CD of each non-joint portion 81 is not the same. . A circumferential length D1 of the non-bonded portion 81 is the same as the length D1 between the adjacent bonded portions 8 , 8 . If the lengths D1 of the non-joint portions 81 in the circumferential direction CD are not the same, as shown in FIG. Preferably, the length D1 is progressively longer. Since the length D1 of the non-bonded portion 81 gradually increases from the end side in the circumferential direction CD of the holder body portion 2 toward the center side, the holder body generally against which the absorbent pad 11 is strongly pressed. In the central region 2C of the portion 2, the shape of the convex portion 9 can be made relatively gentle, and the cushioning property of the central region 2C of the holder main body portion 2 can be further improved.

Adjacent joint portion rows 8R have mutually different arrangement positions of the joint portions 8 in the height direction HD. In the holder 1C, the length D1 in the circumferential direction CD between the adjacent joints 8, 8 is the length D1 between the adjacent joints 8R, 8R, and the length D1 in the circumferential direction CD of the joint 8 L1 is the length L1 of the joint row 8R in the circumferential direction CD (see FIG. 9).

In the holder 1C, a non-joint portion 81 continuously extending in the height direction HD is formed between the adjacent joint portion rows 8R, 8R. When the holder 1B shrinks in the circumferential direction CD, the non-bonded portion 81 protrudes toward the non-skin-facing surface, forming a convex portion 9 continuously extending in the height direction HD. Thus, according to the holder 1C shown in FIG. 9, the same effects as those of the holder 1 shown in FIGS. 1 to 3 can be obtained.
In addition, in the holder 1C, joint portions 8, 8 adjacent in the circumferential direction CD whose arrangement positions in the height direction HD are the same, and joint portions 8, 8 located between the adjacent joint portions 8, 8 in the height direction HD A region surrounded by a total of four joint portions 8 of adjacent joint portions 8, 8 is also a non-joint portion 81a. When the holder 1C shrinks in the circumferential direction CD, the non-joint portion 81a protrudes toward the non-skin-facing surface, so that the convex portion 9 continuously extends in the height direction HD at a position corresponding to the non-joint portion 81a. A different protrusion is formed. In the holder 1C shown in FIG. 9, in addition to the convex portion 9 continuously extending in the height direction HD, a convex portion different from the convex portion 9 is formed, so that the cushion of the holder side fastening structure 6 is formed.

This means that only a convex portion 19 having a lower height than the convex portion 9 formed on the holder-side fastening structure 6 is formed on the skin-facing surface side of the holder-side fastening structure 6 . Since the skin-facing surface of the holder main body 2 is flat, pressure is applied to the tips of the protrusions 19 on the skin-facing surface when the end region of the absorbent pad 11 is pressed against the holder-side fastening structure 6 . Concentration can be prevented, and the external force applied when pressing the absorbent pad 11 can be dispersed over a wide area, so that the discomfort caused by pressing around the waist can be further reduced. From the viewpoint of achieving this effect more remarkably, when the convex portion 19 is formed on the skin-facing surface side of the holder body portion 2, the height of the convex portion 19 with respect to the height H1 of the convex portion 9 is The ratio H2/H1 of the height H2 is preferably 0.95 or less, more preferably 0.90 or less, and even more preferably 0.85 or less. As the ratio H2/H1 is preferably as small as possible, the lower limit of the ratio H2/H1 can be set to 0.0, for example.
The height H1 of the convex portion 9 and the height H2 of the convex portion 19 can be measured by the following method.

<Method for measuring the height of the convex portion>
The holder 1 in the non-stretched state is cut along the circumferential direction CD using a razor while taking care not to deform the protrusions 9 and 19, and the cut surface is observed with a microscope. Vertical heights T1 and T2 from imaginary lines R1 and R2 connecting the surfaces of the joints 8 on both sides of the joint 8 on which the projections 9 and 19 protrude to the apexes of the projections 9 and 19 are measured. Obtain the heights of the protrusions 9 and 19 (see FIG. 3). The average value of the heights T1 of the five protrusions 9 on the skin-facing side is defined as the height H1 of the protrusions 9 on the skin-facing side, and the average of the heights T2 of the five protrusions 19 on the non-skin-facing side. The value is the height H2 of the convex portion 19 on the non-skin facing surface side.
