An underpants-type disposable diaper separately has a front side outer member and a back side outer member, the front side outer member and the back side outer member being spaced apart in a front-back direction in a middle in the front-back direction The back side outer member has a gluteal cover portion extending to a center side of the side seal portions in the front-back direction, and a front-back direction dimension of a side edge of the gluteal cover portion is 0.9 to 1.1 times a width direction dimension from a side edge of the back side outer member to a side edge of a center side of the side seal portions in the width direction.

First welds each slope downward toward the outer side in the width direction. Second welds each slope downward toward the outer side in the width direction. Third welds each slope upward toward the outer side in the width direction. When one first weld, one second weld, and one third weld that are adjacent to one another in the width direction form one weld group, each weld group is configured such that the upper end of the third weld is located downward of the upper end of the second weld, the upper end of the second weld is located downward of the upper end of the first weld, the lower end of the second weld is located downward of the lower end of the first weld, and an extension line extending outward in the width direction from the second weld intersects with the third weld.

An absorbent article includes a first waist region, a second waist region, and a crotch region disposed between the first and second waist regions; and a chassis having a topsheet, a backsheet and an absorbent core. The article also includes a waist feature having a portion extending longitudinally outboard of the chassis in the waist region. The backsheet includes a barrier layer having a maximum length, L.sub.BS. The absorbent core has absorbent material and a maximum length, L.sub.CW. L.sub.CW is substantially the same as L.sub.BS. The absorbent material is disposed in an absorbent material deposition area. The absorbent material deposition area has a maximum length, L.sub.AB, and L.sub.AB is about 90% or greater of L.sub.BS. The first absorbent area lateral edge is disposed a longitudinal distance, D1, from the first barrier lateral edge, and D1 is about 5% or less of L.sub.BS.

A low bulk, high capacity disposable absorbent pant is disclosed. The pant may have a variety of combinations of features that contribute to imparting the pant with a more close-fitting, discreet appearance, particularly under outer clothing, more resembling that of an ordinary undergarment. The features may include an arrangement of relatively closely-spaced elastomeric strands in a belt structure; elastomeric strands in the belt structure having active portions that traverse forward and rearward portions of an absorbent pad assembly; an arrangement of elastomeric strands in the belt structure below the side seams; an arrangement of longitudinal elastic strands in the absorbent pad assembly that are closer to the longitudinal axis of the pant than to the side seams; and/or an absorbent core structure having portions that are tapered and/or channeled.

A method for manufacturing an absorbent article that includes: a first sheet body that includes two first sheets and a first elastic string that is stretchable and contractible in a left-right direction; a second sheet body; and a first weld portion. The method includes: (a) placing the first elastic string in a stretched state where the first elastic string is stretched in the left-right direction between the first sheets disposed in a thickness direction intersecting the left-right direction; (b) causing the second sheet body to overlap with the first sheet body in the thickness direction; (c) releasing the stretched state to bring about a released state; and (d) welding one end portion of the first sheet body in the left-right direction and one end portion of the second sheet body in the left-right direction to each other, to form the first weld portion.

A disposable absorbent pant having a front belt portion and a rear belt portion is disclosed. The front and rear belt portions are joined at side seams and the rear belt portion has a greater length than the front belt portion. A lower edge of the rear belt portion forms at least in part edges of left and right leg openings to the rear of the side seams. The rear belt portion includes first and second layers of nonwoven web material sandwiching a plurality of laterally extending and laterally pre-strained elastic strands, disposed below the side seams. A first of the plurality of elastic strands differs from a second of the plurality of elastic strands by one or more of amount of pre-strain, tensile modulus, decitex, and combinations thereof.

The present disclosure relates to methods for bonding first and second substrates together with tackifier free adhesives. The tackifier free adhesive may be applied to the second substrate to define an adherence zone. The first substrate is positioned on the adherence zone of the second substrate to define a first region and a second region of the adherence zone. In the first region, the tackifier free adhesive is positioned between the first substrate and the second substrate. In the second region, the tackifier free adhesive may or may not be positioned between the first substrate and the second substrate, and may not bond the first substrate with the second substrate. Thus, tackifier free adhesive may be applied to the second substrate to create an adherence zone defining a relatively large area that permits the placement of the first substrate thereon without the need to completely cover the adherence zone.

Disclosed is a pant type absorbent article having a waist guard portion on the back elastic belt, wherein the waist guard portion has a specific location in view of the location from the distal edge to the proximal edge relative to the percentage of the seam length LS, the waist guard portion comprising a waist guard elastic portion having a longitudinal dimension of no greater than about 40 mm, wherein the remainder of the elastic belt superposing the waist guard elastic portion is defined a correlated portion, wherein the tensile stress of the waist guard elastic portion is higher than that of the correlated portion.

Disclosed is an absorbent article having a back elastic belt comprising a waist guard portion extending towards the crotch region from a closed base line towards an open edge, wherein the waist guard portion is partially bonded to the remainder of the back elastic belt to define a pocket.

An absorbent article may have a Product Hip-to-Side Silhouette from 0.5 to about 1.8 and a Relaxed Product Side Length that is greater than about 65% of the Relaxed Product Length. An array of absorbent articles may have an Array Average Product Hip-to-Side Silhouette from about 0.5 to about 1.8.
