Abstract: A liquid permeable surface sheet (3) includes an upper layer non-woven fabric (20) which is provided at the skin side, and which is hydrophilic, and a lower layer non-woven fabric (21) which is provided at the non-skin side, and which is water repellent. Multiple apertures (22) are formed which penetrate the upper layer non-woven fabric and the lower layer non-woven fabric. Accordingly, body fluid transfers smoothly through the apertures to an absorbent body. The upper layer non-woven fabric at the skin side is made to be hydrophilic such that body fluid readily permeates therethrough. The lower layer non-woven fabric at the non-skin side is made to be water repellent such that the body fluid which has passed through is not readily absorbed again. Accordingly, the backflow amount of body fluid can be reduced.

Abstract: A method of manufacturing an absorbent article. The method includes a first step of forming the absorbent body provided with the absorbent body concave portion; a second step of forming core embosses at least on both sides of the absorbent body concave portion by compressing the absorbent body from the skin-contacting side of the absorbent body; and a third step of stacking the liquid permeable topsheet on a top surface side of the absorbent body and forming the embossed portion.

Abstract: An absorbent article in which an absorbent body is provided between a liquid permeable topsheet and a backsheet, includes an absorbent body emboss provided from a front surface side of the absorbent body before stacking the liquid permeable topsheet to surround an area corresponding to a body fluid expelling portion; and a front surface emboss, formed separately from the absorbent body emboss and not to overlap the absorbent body emboss, provided from a front surface side of the liquid permeable topsheet.

Abstract: In an incontinence pad having an absorber 4 interposed between a permeable front surface sheet and a back surface sheet, the absorber is provided with an absorber recessed part, without relying on compression, on a surface of the permeable front surface sheet along an incontinence pad longitudinal direction and over a longitudinal direction range including a body fluid discharge site. By embossing from a front surface of the permeable front surface sheet, an embossed part imparted with an emboss width smaller than a groove width of the absorber recessed part is disposed along the absorber recessed part in the inside of the absorber recessed part.

Abstract: (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).

Abstract: An incontinence pad includes an absorbent body provided between a liquid permeable topsheet and a backsheet, a concave groove formed in a surface of the absorbent body on the liquid permeable topsheet side and extending along an approximately longitudinal direction of the groove, and a highly compressed portion formed in a bottom surface of the concave groove. The highly compressed portion includes a sloping element in a unit portion formed by dividing the concave groove in a longitudinal direction thereof and crossing the concave groove from one side edge to the other side edge, and is formed into a pattern obtained by repeatedly inverting the highly compressed portion of the unit portion in the longitudinal direction.

Abstract: (Object) To prevent leakage of body fluids and to readily transmit pressure from both sides to a center portion in a width direction by bringing an absorbent article into close contact with a crotch area extending from a body fluid discharge portion to a start position of the intergluteal cleft.
(Means of Achieving the Object) A pair of right and left compressed grooves (8, 8) that extend in an approximately longitudinal direction is formed on a surface of a liquid permeable top sheet (3). The compressed grooves (8) have separation distance reduced regions (11), in which a separation distance between the right and left compressed grooves is reduced, formed at the back of a region corresponding to a body fluid discharge portion (H) of a wearer, and also have vastly enlarged portions (10), in which widths of the compressed grooves (8) are enlarged, formed at positions within the separation distance reduced regions (11) and where the separation distance between the right and left compressed grooves (8, 8) becomes minimum.
