A disposable absorbent article is disclosed that is partially defined by a pair of longitudinally extending side edges and a pair of end edges extending between the side edges, and includes a topsheet layer, a backsheet layer, and an absorbent core disposed between the topsheet and the backsheet. The disposable absorbent article also has a pair of side wall structures each having a pair of oppositely positioned end portions. A first side wall structure extends generally longitudinally between the core and one of the side edges and the other side wall structure extends generally longitudinal between the core and the other side edge. Further, an end strip constructed from an elastic material is positioned substantially adjacent each one of the end edges, and extends laterally between the side edges. Each of the end strips includes a fixed elastic end section disposed adjacent the end edge and secured to the topsheet, a fixed intermediate section positioned longitudinally inward of the fixed end section, and a movable, elastic inward section positioned longitudinally inward of the intermediate section.

Disposable absorbent article with containment structure

A disposable absorbent article partially defined by a pair of longitudinally extending side edges and a pair of end edges extending between the side edges, includes a topsheet layer, a backsheet layer, and an absorbent core disposed between the topsheet and the backsheet. The disposable absorbent article also has a pair of side wall structures each having a pair of oppositely positioned end portions. A first side wall structure extends generally longitudinally between the core and one of the side edges and the other side wall structure extends generally longitudinally between the core and the other side edge. Further, an end strip constructed from an elastic material is positioned substantially adjacent each one of the end edges, and extends laterally between the side edges. Each of the end strips includes a fixed elastic end section disposed adjacent the end edge and secured to the topsheet, a fixed intermediate section positioned longitudinally inward of the fixed end section, and a movable, elastic inward section positioned longitudinally inward of the intermediate section. The fixed elastic section forms a waistband portion each of the front and back waist regions of the article. The intermediate section has a plurality of voids or apertures which are employed to substantially de-elasticize the intermediate section. The inward section includes a central portion spaced from the topsheet and the absorbent core, and a pair of side portions. These side portions are secured to the end portions of the side wall structures, thereby applying a contractile force between the side wall structures such the side wall structures (as well as the side edges of the article) are biased upwardly. The side wall structures and the inward sections are, therefore, secured to one another and disposed to define the sidewalls of a relatively deep containment pocket located in the crotch region.

A method for formation of shaped components such as shaped absorbent cores, for disposable absorbent articles, contemplates that a relatively wide web of material be provided from which the components are cut. The web of material is longitudinally slit to form a plurality of subdivided webs each having shaped components arranged in serial relationship. The shaped components of adjacent ones of the subdivided webs are nested with each other, that is, a line extending longitudinally of the web extends through the components of adjacent subdivided webs. Efficient formation is facilitated by collecting the marginal portions of the web of material, and at least partially recycling the collected portions for formation of the wide web.

Method of making shaped components for disposable absorbent articles

A disposable absorbent article includes a topsheet, a backsheet and an absorbent core disposed therebetween. One or more of the backsheet, topsheet, and absorbent core is constructed of an absorbent composite that includes an absorbent layer of hydratable fine fibers in the form of microfibril obtained from cellulose or a derivative thereof and super absorbent polymer (SAP) particles bonded together by the hydratable fibers, and a nonwoven substrate supporting the absorbent layer such as SMS. The absorbent layer is coated over the surface of the nonwoven substrate. The core may include one uniform layer of the absorbent composite or a composite having one layer of the nonwoven substrate and a plurality of segmented absorbent layers applied thereon. In the latter design, the absorbent layers are spaced apart from one another to expose surface sections of the substrate. These non-coated surface sections provide wicking zones which allow room for the absorbent layers to expand and prevent gel blocking.

Disposable absorbent article employing an absorbent composite and method of making the same

A disposable absorbent article defined by a pair of longitudinally extending side edges and a pair of end edges extending between the side edges, has a front waist region, a back waist region, and a crotch region located between the waist regions. The disposable absorbent article also includes a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet. The topsheet is provided with a plurality of openings which direct bodily exudates received into or by the crotch region to a storage space disposed below the topsheet. The topsheet is spaced generally upward from the core such that the storage space is disposed between the topsheet and the core. The disposable absorbent article further includes at least one or more elongated elastic strands which are attached to the topsheet so as to space or urge the topsheet generally upwardly from the core. Moreover, portions of the topsheet between the elastic strands are tacked down to create depressions between the strands and each of the openings are located generally in one of these depressions.

Disposable article with containment structure

An absorbent article, such as a disposable diaper, disposable training pants, feminine hygiene products or an incontinent adult article, containing aloe vera on at least the surface of the article contacting the wearer's skin to reduce rash and methods of making same.

Absorbent articles with improved rash-preventing properties

A method for making a disposable garment with de-elasticed elastic members in the crotch area of the garment is disclosed using means for de-elasticing the elastic members such as macerators, chemicals, selective laser beams, heat, and freezing.
