[Problem] To prevent separation and accompanying tearing of a front-surface sheet when non-heat-fusible fibers are used in the front-surface sheet.

[Solution] An absorber 4 is interposed between a front-surface sheet 3 and a back-surface sheet 2, and side sheets 7 are disposed on both side portions along the longitudinal direction. The front-surface sheet 3 contains non-heat-fusible fibers, and the side sheets 7 contain a heat-fusible resin. The front-surface sheet 3 is interposed between the laminated side sheets 7 on the outer side in the width direction than the absorber 4 whereby a side flap portion SF in which the side sheet 7, the front-surface sheet 3, the side sheet 7, and the back-surface sheet 2 are laminated in that order from the skin side is formed. A fusing portion 10 in which the sheets forming the side flap portion SF are integrally heat-fused is provided in a region of the side flap portion SF including at least the front and back ends of a sanitary napkin 1.

Problem

To suppress skin touch feeling from being deteriorated and further provide excellent wearing feeling, while ensuring sufficient adhesive strength in an adhesion part of a side sheet.

Solution

In the present invention, a pair of left and right side sheets 7 are provided over the entire length of both side parts on a skin-contact surface. A sanitary napkin 1 includes overlapped regions T where a front-surface sheet 3 and the side sheets 7 are overlapped with each other, on the both side parts of the sanitary napkin 1 along the longitudinal direction. In each of the overlapped regions T, a side-sheet embossed part 10 is formed on the side sheet 7, and an inter-sheet embossed part 9 is formed to make the side sheet 7 and the front-surface sheet 3 adhere to each other. The total area of the side sheet embossed part 10 is formed smaller than the total area of the inter-sheet embossed part 9.

ABSORBENT ARTICLE WITH AN ABSORBENT SYSTEM HAVING AN ANNULAR OPENING

An absorbent article can have a topsheet layer, a backsheet layer, and an absorbent system positioned between the topsheet layer and the backsheet layer. The absorbent system can have at least a fluid intake layer, an absorbent core, and a distribution layer. The fluid intake layer and the absorbent core can define an aligned annular opening in the absorbent system and can maintain the topsheet layer in a spaced apart relationship from the distribution layer.

Disposable hygiene article with improved fit

The present invention relates to a disposable hygiene article comprising a pair of curved compression lines in a rear portion of the article. The article has a core with a first region which has its narrowest width (M) in the transverse direction (x) in a front portion or at a location of a transition between the front portion and a crotch portion of the article. The absorbent core in the rear portion comprises the first (L1, R1) and second (L2, R2) pairs of rear compression lines, which extend in a longitudinal direction (y) between respective front and rear endpoints. A transverse distance (G3min) separates the rear endpoints of the pair of compression lines whilst a second, larger distance (G3max) separates the front endpoints of the compression lines.

ABSORBENT ARTICLES INCLUDING HIPE FOAM ENHANCED WITH CLAY NANOPLATELETS, AND METHOD OF MANUFACTURE

Open-cell foam having a structure of interconnected struts formed of polymeric material and defining open cells, resulting from polymerization of a continuous phase of a high internal phase water-in-oil emulsion, the struts comprising the polymeric material with clay nanoparticles at least partially captured therewithin, is disclosed. The clay nanoparticles may be present in combination with a surface modifier. Methods for making the open-cell foam are also disclosed. Absorbent articles including the open cell foam are also disclosed.

An absorbent article, such as a sanitary napkin, a pantiliner or an incontinence pad, which improves diffusion property of a body fluid and maintains a stable absorption amount. In FIG. 3, a sanitary napkin (1) includes an absorber (4) including an upper layer sheet (10) disposed at a skin side, a lower layer sheet (11) disposed at a non-skin side, and a highly water-absorbing polymer (12) disposed between the upper layer sheet (10) and the lower layer sheet (11). The upper layer sheet (10) is provided with a plurality of protruding portions (14) bulging out to the skin side and forming space portions (13) to be filled with the highly water-absorbing polymer (12), and a joined portion (15) in which the upper layer sheet (10) and the lower layer sheet (11) are joined to each other intermittently on the peripheral edges of the protruding portions (14) along the circumferential directions.

Absorbent articles with multi-pieces acquisition layer

An absorbent article having a front side, a back side, a longitudinal axis notionally extending in a longitudinal direction from the middle of the front side to the middle of the back side. The absorbent article has a length L measured along the longitudinal axis. The absorbent article comprises a liquid permeable topsheet on the wearer-facing side, a liquid impermeable backsheet on the garment-facing side, an absorbent core between the topsheet and the backsheet, and an acquisition layer comprising two or more discrete longitudinally-orientated stripes of an acquisition material between the topsheet and the absorbent core. The topsheet forms recesses at the surface of the absorbent article in the gaps between the stripes.
