Description

  The present invention relates to a pants-type absorbent article. The present invention also relates to an annular belt-shaped pad holder used for holding an absorbent pad.

  Conventionally, in a pants-type disposable diaper, the waistline elastic member disposed on the waistline part is fixed to a member other than the outermost layer sheet forming the outer surface of the diaper, and is not joined between the waistline elastic member and the outermost layer sheet. A technique is known in which gathers are formed on the inner side of the outermost layer sheet by providing a region, while gathers are not formed on the outer surface of the waistline portion (see Patent Document 1). This type of pants-type disposable diaper has an advantage that it has a clean appearance because no gathers are formed on the outer surface of the waistline. When such a pants-type disposable diaper is continuously produced, a through hole or a notch for forming a leg opening is formed in the strip-shaped original fabric of the exterior body including the outermost layer sheet, and unnecessary portions are removed as trims. It is common.

  Apart from such pants-type disposable diapers, the outer body is divided into an abdominal outer body disposed on the wearer's ventral side and a back side outer body disposed on the wearer's back side, and absorbs A pants type in which the main body is fixed so as to cross over the abdominal exterior body and the back exterior body, and the left and right side edges of the abdominal exterior body are joined to the left and right side edges of the back side exterior body Disposable diapers are also known (see, for example, Patent Documents 2 and 3). According to this diaper, unlike the diaper described in Patent Document 1, it is not necessary to remove the trim from the original fabric of the exterior body, and the amount of trim to be removed can be reduced.

One auxiliary sheet 24 is arranged on the ventral exterior body 2A. Similarly, one sheet is also provided on the backside exterior body 2B. As shown in FIG. 3, one end edge in the Y direction of the auxiliary sheet 24 is substantially at the same position as an end edge of the inner layer sheet 23 located on the side of the waist opening edge W in the Y direction. On the other hand, the other edge of the auxiliary sheet 24 in the Y direction extends beyond the edge 3W in the Y direction of the absorbent main body 3 and on the top sheet 31 of the absorbent main body 3. Therefore, the skin contact surface of the diaper 1 is constituted by the extending portion 221 of the sheet 22 a constituting the outer layer sheet 22, the auxiliary sheet 24, and the top sheet 31.

  As shown in FIG. 3, the abdominal exterior body 2A has an upper abdominal region A2 and a lower abdominal region A3 that is adjacent to the upper abdominal region A2 and located on the crotch C side with respect to the upper abdominal region A2. In other words, the lower abdominal region A3 is located closer to the crotch C than the upper abdominal region A2. In the present embodiment, the ventral-side exterior body 2A further includes a waist region A1 including a waist opening edge W. The waist region A1 is adjacent to the upper abdominal region A2 and is located closer to the waist opening edge than the upper abdominal region A2. The upper abdominal region A2 is on the waist opening edge W side with respect to the edge 3W in the Y direction of the absorbent main body 3 fixed to the abdominal exterior body 2A, and is an area where three layers of sheets are laminated. In the diaper 1 of the present embodiment, the upper abdominal region A2 is configured by the outer layer sheet 22, the inner layer sheet 23, and the auxiliary sheet 24. In addition to this, the upper abdominal region A <b> 2 may be configured by a combination of arbitrary three or more layers of the outer layer sheet 22, the extending part 221, the inner layer sheet 23, and the auxiliary sheet 24. In this embodiment, the part comprised by four layers, the outer layer sheet | seat 22, the extension part 221, the inner layer sheet | seat 23, and the auxiliary sheet | seat 24 is also contained in upper abdominal part area | region A2. Although not shown, the back side exterior body 2B in the diaper 1 is also in the same order as the abdominal side exterior body 2A from the waist opening edge W side toward the crotch C side in order from the waist region B1, the upper back region B2, and the lower side. It has a back region B3. In the present specification, the upper abdominal region A2 and the upper back region B2 are collectively referred to as an “upper trunk region”, and the lower abdominal region A3 and the lower back region B3 are collectively referred to as a “lower torso region”. The waist regions A1 and B1 extend in the Y direction of the diaper 1 from the waist opening edge W to the edge located on the side of the waist opening edge of the inner layer sheet 23 in the Y direction. In the upper body regions A2 and B2, the outer layer sheet 22 and the inner layer sheet 23 are joined by the adhesive H from the lower end of the waist elastic member 51 located closest to the crotch portion C in the Y direction of the diaper 1. It extends to the top of the area. Furthermore, lower trunk | drum area | region A3, B3 is 2 A (back side exterior body 2B) from the upper end of the area | region where the outer layer sheet 22 and the inner layer sheet 23 are joined by the adhesive agent H in the Y direction of the diaper 1. ) To the lower end edge 2d.

  The waist region A1 extends in a band shape in the X direction of the diaper 1 along the waist opening edge W in the ventral exterior body 2A. In the waist region A1, a plurality of thread-like or belt-like (in the illustrated example, five) waist elastic members 51 extend in the X direction of the diaper 1 and extend in the X direction. It is fixed between the extended portions 221 of 22a. The number of the waist elastic members 51 is preferably 3 or more, more preferably 5 or more in the waist region A1. And, preferably 20 or less, more preferably 15 or less. Specifically, it is preferable that 3 to 20 are provided, and more preferably 5 to 15. As shown in FIG. 3, the waist elastic member 51 has an adhesive (not shown) applied to substantially the entire inner surfaces facing each other by folding back the extending portion 221 of the sheet 22a constituting the outer layer sheet in the waist region A1. Is fixed. The waist elastic member 51 is disposed over the entire area between the side seal portions 4 and 4 in the ventral exterior body 2A. In the wearing state of the diaper 1, the waist elastic member 51 contracts to cause a large number of wrinkles or irregularities in the outer layer sheet 22 to form a waist gather G <b> 1 (see FIG. 1).

  The upper abdominal region A2 located adjacent to the waist region A1 also extends in a strip shape in the X direction of the diaper 1. As shown in FIG. 3, the outer layer sheet 22 and the inner layer sheet 23 are not joined in the upper abdominal region A2. At the same time, in the upper abdominal region A2, a thread-like or belt-like upper body elastic member 71 extends in the X direction of the diaper 1 and is fixed to the inner layer sheet 23 in the state of being extended in the X direction. The upper torso elastic member 71 is a combination of the upper abdominal elastic member and the upper back elastic member. In the present specification, the upper torso elastic member 71 is used alone or in the case where both are included. The upper body elastic member 71 is disposed between the inner layer sheet 23 and the auxiliary sheet 24 and is fixed to both the inner layer sheet 23 and the auxiliary sheet 24. On the other hand, the elastic member for gathering is not fixed to the outer layer sheet 22 in the upper abdominal region A2. For example, an adhesive (not shown) is used for fixing the upper body elastic member 71. Two or more upper body elastic members 71 are preferably arranged. And, preferably 10 or less, more preferably 5 or less. Specifically, 2 to 10 are preferably arranged, and more preferably 2 to 5. When the diaper 1 is worn, the inner body sheet 23 and the auxiliary sheet 24 have a large number of wrinkles or irregularities due to the contraction of the upper body elastic member 71 to form an inner gather (not shown). Since the inner gathers are located on the inner side of the outer layer sheet 22 that is not joined to the inner layer sheet 23, the inner gathers are hardly visible from the outer surface of the diaper 1. As a result, the outer layer sheet 22 has an underwear-like appearance. Further, the outer layer sheet 22 that is not joined to the inner layer sheet 23 in the upper abdominal region A2 has a bulging portion R that bulges outward from the diaper 1 due to contraction of the inner gathers as shown in FIG. It becomes a shape and gives a soft impression to the user, and the appearance is further improved by a synergistic effect with the appearance of underwear.

  In the present invention, the “non-bonded state” is not limited to the case where the outer layer sheet 22 and the inner layer sheet 23 are unbonded over the entire surface between the left and right side seals 4 and 4 in the upper abdominal region A2. Even in the case where the sheets are partially joined, those in which the influence of gathering of the inner sheet is substantially suppressed are not excluded and are included in the “non-joined state”. The diaper 1 is preferably worn so that the upper abdominal region A2 or the upper back region B2 contacts the site from the wearer's iliac crest to the upper anterior iliac spine. Specifically, it is as follows. In the upper abdominal region A2, the region where the outer layer sheet 22 and the inner layer sheet 23 are not joined to the entire area (extended state) of the region where the inner layer sheet 23 between the side seal portions 4 and 4 is present is 85% or more, particularly 90%. % Or more is preferable. The length L1 in the Y direction of the non-bonded region is 1% or more, particularly 2% or more, of the total length L (see FIG. 2) of the diaper 1 in the Y direction. And it is 12% or less, especially 9.5% or less. Specifically, it is 1 to 12%, particularly 2 to 9.5% from the viewpoint that a wide range of the outer surface of the diaper is a flexible and soft area, and the diaper gives a soft impression. preferable. Further, the upper abdominal region A2 is 5% or more, particularly 10% with respect to the length between the waist opening end and the leg opening end (that is, the total length in the Y direction of the side seal 4 of the abdominal portion A). That's it. And it is 70% or less, especially 50% or less. Specifically, having a length in the Y direction of 5 to 70%, particularly 10 to 50%, from the viewpoint of giving an underwear-like and soft appearance, from the viewpoint of suppressing slipping off, and for the purpose of gently and firmly suppressing the waistline preferable. Moreover, since the area | region which swells becomes moderate, the effect which gives a wearer visually that it is hard to give a wearer's impression to a wearer, and has elasticity.

  In the lower abdominal region A3 adjacent to the upper abdominal region A2 and below the upper abdominal region A2, that is, on the crotch C side of the upper abdominal region A2, the outer layer sheet 22 and the inner layer sheet 23 are adhesives. Joined by H. In the lower abdominal region A3, the skin contact surface side of the inner layer sheet 23 and the back sheet 32 of the absorbent main body 3 are also joined by an adhesive (not shown). The adhesive used for joining the outer layer sheet 22 and the inner layer sheet 23 is applied, for example, by a solid solid coating or a spiral or ohmic pattern. On the other hand, the adhesive used for joining the skin contact surface side of the inner layer sheet 23 and the back sheet 32 of the absorbent main body 3 is applied so as to extend in the Y direction at the position of the central region in the X direction of the absorbent main body 3. Or is applied over the entire area opposite to each other.

  In the lower abdominal region A3, as shown in FIG. 2, a thread-like or belt-like lower portion is formed between the outer layer sheet 22 and the inner layer sheet 23 at a position outside the side edge extending in the Y direction of the absorbent main body 3 in the X direction. A body elastic member 91 is disposed. In addition, the lower trunk | drum elastic member 91 expresses a lower abdominal part elastic member and a lower back part elastic member collectively, and is used by the case where each is included in this specification, when both are included. The lower body elastic member 91 extends in the X direction. The lower torso elastic member 91 is joined to the outer layer sheet 22 and the inner layer sheet 23 by an adhesive (not shown) in an extended state. In the lower abdominal region A3, the elastic member 91 is not disposed at a portion overlapping the absorbent main body 3. In the natural state of the diaper 1, a large number of wrinkles or irregularities are generated in the outer layer sheet 22 and the inner layer sheet 23 due to the contraction of the lower body elastic member 91, and the lower body gather G3 is formed as shown in FIG. 1. Yes.

  According to the diaper 1 of the present embodiment having the above configuration, the outer layer sheet 22 and the inner layer sheet 23 are not joined in the upper abdominal region and are formed by contraction of the upper abdominal elastic member 71. Since the inner gathers (not shown) are located on the inner side of the outer layer sheet 22, it is difficult to visually recognize the inner gathers from the outer surface of the diaper 1, and as a result, the diaper 1 has a clean appearance. Moreover, due to the contraction force of the inner gathers, the diaper 1 is effectively prevented from slipping off in the wearing state. The falling of the diaper 1 is also prevented by the contraction force of the lower abdomen elastic member 91 arranged in the lower abdomen region. And since the exterior body as a continuous extension part from the ventral-side exterior body 2A is not arranged on the crotch part C, even if the crotch part C is deformed due to the wearer's posture in the wearing state, the deformation Is difficult to propagate to the ventral exterior body 2A, and the twitching of the ventral exterior body 2A is effectively suppressed. As a result, the outer layer sheet 22 easily floats from the inner layer sheet 23 in the upper abdominal region, and the above-described bulging portion R is successfully formed. Due to this, the air permeability and moisture permeability of the upper abdominal region in the wearing state are improved. Moreover, since the swaying of the outer layer sheet 22 in a wearing state is suppressed, the appearance of the diaper 1 is improved.

  In the diaper 1 described above, the top sheet 31, the back sheet 32, the absorber 33, the side cuff 34 forming sheet, and the like are particularly limited to various types conventionally used for absorbent articles such as disposable diapers.

Those coated with a core wrap sheet can be used.

  Moreover, as the outer layer sheet 22, the inner layer sheet 23, and the auxiliary sheet 24, various sheet materials conventionally used for absorbent articles such as disposable diapers can be used without particular limitation. From the viewpoint of improving the air permeability and moisture permeability of the upper abdominal region A2, it is preferable that these sheets 22, 23, 24 have air permeability. In particular, it is preferable to use a nonwoven fabric. As the nonwoven fabric, various nonwoven fabrics such as an air-through nonwoven fabric, a spunbond nonwoven fabric, a spunlace nonwoven fabric, a melt blown nonwoven fabric, and a heat roll nonwoven fabric are preferably used as a single layer or as a laminated nonwoven fabric in which these are laminated in two or more layers. . Moreover, as these sheets 22, 23, and 24, a sheet or the like in which a nonwoven fabric and a film are integrated can be used.

  Examples of the material for forming the elastic members 51, 71, 91 include synthetic rubbers such as styrene-butadiene, butadiene, isoprene, and neoprene, natural rubber, EVA, stretchable polyolefin, and polyurethane. As the form of the elastic member, a thread-like (thread rubber etc.) or a strip (flat rubber etc.) having a rectangular, square, circular, elliptical or polygonal cross section, a multifilament type thread-like one, etc. is preferable. Can be used. The thickness of the elastic members 51, 71, 91 is preferably 310 dtex or more, particularly 470 dtex or more, and more preferably 620 dtex or more.
