Absorbent article

Abstract

[Problem] To reliably prevent rear leakage. [Solution] A sanitary napkin 1 comprises: a plurality of widthwise compressed grooves 10, 10... which are disposed in a region to the rear of a region corresponding to a bodily fluid discharge part H of a wearer, extend in a substantially widthwise direction of the sanitary napkin 1, are formed in a shape bulging toward the rear, and are arranged at intervals in the longitudinal direction of the sanitary napkin 1; and a right and left pair of longitudinally compressed grooves 11, 11 which extend along substantially the longitudinal direction of the sanitary napkin 1 and are each arranged on the outside in the width direction at a predetermined separating distance from the widthwise compressed grooves 10. The widthwise compressed grooves 10 are formed such that the groove widths and lengths thereof become gradually larger as the widthwise compressed grooves 10 are arranged relatively closer to the rear of the sanitary napkin 1.

Description

technical field [0001] The present invention mainly relates to absorbent articles such as sanitary napkins, secretion pads, incontinence pads, toiletry appliances, etc., and more specifically relates to an absorbent article in which a pressing groove recessed toward the non-skin side is formed on the rear portion of the skin-contacting surface . Background technique [0002] Conventionally, as the above-mentioned absorbent article, it is known to sandwich a liquid-impermeable back sheet such as a polyethylene sheet or a polyethylene sheet laminated with a non-woven fabric and a liquid-permeable top sheet such as a non-woven fabric or a liquid-permeable plastic sheet. An absorbent article provided with an absorbent body made of cotton pulp or the like. [0003] Many improvements have been made on such absorbent articles, and in order to prevent leakage of bodily fluids, absorbent articles having squeeze grooves of various shapes have been developed. For example, the followi...

Problems solved by technology

[0007] However, in the absorbent article described in the above-mentioned Patent Document 1, there is a concern that due to the first flexible shaft extending in the longitudinal direction and the second A horizontal flexible shaft connected between the flexible shafts surrounds the central absorbent portion, so that the body fluid absorbed in the central absorbent portion and becomes saturated overflows from a part of the surrounding first flexible shaft and the lateral flexible shaft , thus creating a leak in the overflowed part of the

[0008] In addition, in the absorbent article described in the above-mentioned Patent Document 2, there is a concern that, in the rear portion, the rear squeeze groove of a shape that bulges toward the rear side A plurality of them are arranged at intervals in the longitudinal direction, and when the body fluid intercepted by the rear squeeze groove overflows to both sides from the area surrounded by the rear squeeze groove, leakage from the side occurs.

[0009] Like this, in the existing absorbent articles, especially against leakage from the rear, sufficient countermeasures have not been taken, and there is still room for further improvement
