Problems solved by technology

However, if openings are provided on the entire surface material layer, body fluids will permeate through the surface material layer on the side portions protruding from the absorber, so there is a disadvantage that body fluids tend to leak to both sides.
In addition, since the opening is only formed on the surface material layer, the liquid passing through the opening will easily flow to the side along the surface of the absorber at the interface between the absorber and the surface material layer, so there is also the possibility of side leakage.

Embodiment Construction

[0026] Hereinafter, embodiments of the present invention will be described by taking the absorbent article of the present invention as an example with reference to the drawings. Fig. 1(A) is a schematic cross-sectional view of the longitudinal central part of the absorbent article, Fig. 1(B) is a partially enlarged view thereof, Fig. 2(A) is a top view, and Fig. 2(B) is a partially enlarged view thereof picture.

[0027] The absorbent article of the present invention is a thin article suitable for absorbing a relatively small amount of body fluid, that is, leucorrhea excreted from female genitals, a small amount of menstrual blood, and the like, and is called a panty liner. The absorbent article basically has a liquid-permeable surface material layer 1, a liquid-impermeable back surface material layer 2, and an absorbent body 3 sandwiched between the two layers, which is narrower in width than the two layers, and a liquid-permeable surface material layer. 1 and the liquid-imp...

Abstract

Disclosed is an absorbent article including a liquid-permeable top material layer, a liquid-impermeable back material layer, and an absorbent body that is narrower than the top material layer and the back material layer and disposed between the top material layer and the back material layer such that longitudinally extending side edges of the absorbent body are individually inwardly spaced apart from corresponding side edges of the top material layer and the back material layer. Along the individual side edges of the absorbent body, the top material layer is embossed to have compressed portions that are formed in a substantially continuous, longitudinally extending pattern.

Description

technical field [0001] The present invention relates to an absorbent article, especially a thin absorbent article suitable for absorbing a small amount of excreted body fluid, such as a panty liner. technical background [0002] Panty liners used to treat leucorrhea, etc., need to deal with a small amount of body fluids. Although they do not need a large absorbency, they must be articles that can perform the absorbing function. In addition, because it is used for daily use, it is best to feel wearing Small. Also, for the comfort of the wearer, it is desirable to have an aesthetic design. Therefore, as described in the following Patent Document 1 and Patent Document 2, the existing panty liner has a narrow and small shape suitable for the crotch portion of the panty, and the overall thickness of the liner is reduced by using a thin absorbent body. Thin, non-woven fabrics with soft feeling, good liquid permeability, relatively bulky, and many voids are usually used for the s...
