Abstract

An absorber includes a concave groove-shaped body fluid inflow portion along a longitudinal direction of an incontinence pad and over a range in the longitudinal direction including a body fluid discharge portion of a wearer, and a granular powder superabsorbent resin is arranged at least on a side edge portion of the absorber and over the range in the longitudinal direction including the body fluid inflow portion. Since the body fluid flowing into the body fluid inflow portion is diffused and is absorbed and held in the superabsorbent resin on the side edge portion of the absorber, it is possible to provide an adequate absorbed amount in the absorber despite the concave groove in the absorber. Even when the superabsorbent resin becomes swollen with absorbed body fluid, the body fluid inflow portion is not blocked, with the result that the absorption speed is not reduced.

First claim

The invention claimed it:

1. An absorbent product comprising,
an absorber interposed between a liquid-permeable front surface sheet and a back surface sheet, and a side non-woven fabric arranged at each of left and right sides of the absorber on a skin side along a longitudinal direction of the absorbent product,
wherein the absorber includes only one concave groove-shaped body fluid inflow portion and said only concave groove-shaped body fluid inflow portion extends along the longitudinal direction of the absorbent product on a line which is at a center of a width of the absorbent product and over a range in the longitudinal direction including a body fluid discharge portion of a wearer of the absorbent product, and a granular powder superabsorbent resin is intensively provided at least on a side edge portion of the absorber and over the range in the longitudinal direction including the body fluid inflow portion, and
wherein the superabsorbent resin is not arranged on a surface of the skin side of the absorber in an entire zone in a width direction of the absorber between the side non-woven fabrics arranged at the left and right sides of the absorber, and the superabsorbent resin is intensively provided on a surface of the absorber on the skin side overlapping the side non-woven fabrics and over a range in the longitudinal direction including the body fluid inflow portion.

2. The absorbent product according to claim 1 ,
wherein the superabsorbent resin is arranged on a surface of the absorber on a non-skin side and over the range in the longitudinal direction including the body fluid inflow portion.

3. The absorbent product according to claim 1 ,
wherein the absorber is surrounded by a wrapping sheet, and
the superabsorbent resin is fixed either to both the absorber and the wrapping sheet or to one of the absorber and the wrapping sheet.

4. The absorbent product according to claim 1 ,
wherein the body fluid inflow portion is formed either with an opening through which the absorber penetrates from the skin side to the non-skin side or with a concave portion that is recessed from the skin side to the non-skin side and that has a bottom.
