An absorbent article and method of making the absorbent article are disclosed. The absorbent article having a topsheet, a backsheet, and an absorbent core structure having one or more layers wherein at least one layer is a heterogeneous mass layer, wherein the topsheet and the heterogeneous mass are integrated such that they reside in the same X-Y plane.

A base sheet having one main surface applied with an adhesive is supplied to a conveyance device and the base sheet is conveyed while the other main surface of the base sheet is suctioned. A first laminate is formed by overlapping the one main surface of the base sheet with the other main sheet of a fiber sheet having one main surface nap-raised; then, a granular absorbent material is scattered on the one main surface of the fiber sheet; the scattered absorbent material is infiltrated into the fiber sheet when the other main surface of the base sheet is suctioned; then, a second laminate is formed by overlapping the one main surface of the fiber sheet with the one main surface of a cover sheet applied with an adhesive; and then the resultant sheet is compressed in the thickness direction by means of a compression means and the applied adhesive.

A substantially planar absorbent core (28) extending in a transversal direction (x) and a longitudinal direction (y), and comprising a core wrap (16, 16′) enclosing an absorbent material (60) substantially free of cellulose fibers, the absorbent material forming a pattern of discrete absorbent material areas. The pattern comprises transversally-orientated areas (752) and longitudinally-orientated areas (754). The absorbent core may further comprise at least two longitudinally-orientated channel-forming areas (26).

(Object) To prevent a high compression portion from being defectively formed and also a top sheet from being torn. (Means of Achieving the Object) A sanitary napkin (1) in which a low compression portion (15) and a high compression portion (16, 17, 18) are formed on a bottom surface of a compressed groove (10) that is recessed from a skin contact surface side. The high compression portion includes regularly-arranged high compression portions (16) that are regularly arranged in a longitudinal direction of the compressed groove (10), a large-area high compression portion (17) that is irregularly arranged in the compressed groove (10) and has an area larger than an area of each of the regularly-arranged high compression portions (16), and an auxiliary high compression portion (18) that is arranged at one side, in a longitudinal direction of the napkin, of the large-area high compression portion (17) through the low compression portion (15) so as to surround the one side, in the longitudinal direction of the napkin, of the large-area high compression portion (17).

The present invention aims to achieve both a function of diffusing excretions or the like in a longitudinal direction of an absorber and maintenance of adhesion to a wearer in a direction orthogonal to the longitudinal direction. The absorber includes a top sheet (21), a back sheet (22) opposed to the top sheet (21), and an absorbent core (23) extending in a predetermined longitudinal direction between the top sheet (21), and the back sheet (22) and configured to absorb excretions or the like of the wearer. The absorbent core (23) has a plurality of opening portions (23a) each having a shape that opens toward the top sheet (21) and extends in the longitudinal direction and each arranged in the longitudinal direction. An interval (G1) in the longitudinal direction between two opening portions (23a) adjacent to each other among the plurality of opening portions (23a) is set to a dimension equal to or larger than a dimension (D1) in the longitudinal direction of each of the two adjacent opening portions (23a).

A disposable absorbent article may include a chassis that includes a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet; and a leg gasketing system. The leg gasketing system may include an inner cuff and an outer cuff; the inner cuff may include an inner cuff folded edge and an inner cuff material edge and the outer cuff may include an outer cuff folded edge and an outer cuff material edge such that the web of material is folded laterally inward to form the outer cuff folded edge and folded laterally outward to form the inner cuff folded edge, and the leg gasketing system further including a leg gasketing system pocket with an opening on an inboard longitudinal edge of the leg gasketing system pocket. The disposable absorbent article also includes at least one channel in the absorbent core.

An absorbent article includes an absorbent core. The absorbent core includes an absorbent component enclosed by a core cover. The absorbent component includes a coherent area having an extension of the absorbent article and having an extension in the transverse direction over a full width of the absorbent component, the coherent area having a front edge and a back edge. The absorbent component includes high density areas of absorbent material alternating with low density areas of absorbent material. The high density areas and the low density areas extending in the longitudinal direction of the absorbent article in the front portion and/or in the crotch portion of the absorbent article. The back portion of the absorbent article includes a conformance zone comprising absorbent material. The coherent area and the conformance zone are separated by an area substantially free from absorbent material.

A pad capable of enhancing the fitting performance to a wearer. An absorber includes a front body portion, a back body portion, and a narrowing portion, whose width dimension is reduced, provided between the front body portion and the back body portion. A first groove extending in the front-back direction is formed in a central portion in the width direction of the absorber. A third groove extending in the width direction is formed in a central portion in the front-back direction of the narrowing portion. A second groove extending in the width direction is formed in a front side portion in the front-back direction of the narrowing portion. A fourth groove extending in the width direction is formed in a back side portion in the front-back direction of the narrowing portion.
