Problems solved by technology

[0003] However, when the absorber is thinned in order to improve the fit when worn, or the rigidity of the absorber is reduced by opening a part of the absorber, the front sheet positioned at the crotch portion tends to wrinkle, and the front sheet The anti-leakage effect brought by the concave-convex shape is reduced, and soft stool or urine tends to flow along the pleats and leak out

Embodiment Construction

[0052] If, as in the technology described in Patent Document 3, irregularities with a height difference higher than the irregularities arranged between them are formed in the side regions of the top sheet arranged on both sides of the absorber, the absorbent article will be When stored in the state compressed and filled in a packaging bag by packaging, the pressure will concentrate on the high protrusions existing in the side area, and it is difficult to maintain the height of the protrusions. When the degree of compression is increased or the storage period is extended, The leak-proof effect due to unevenness may be reduced.

[0053] In addition, in the case where the side region having continuous or rowed convex portions is formed on the front sheet in the longitudinal direction of the absorbent article, the absorbent article shrinks in the longitudinal direction due to three-dimensional gathers or leg gathers, etc. When pleats appear in the side area, the leak-proof effect ...

Abstract

An absorbent article (1), which includes a front sheet (12), a back sheet (13) composed of a composite sheet, and an absorbent body (14) arranged between the two sheets. The composite sheet (10) has a structure along The first direction (X) along the length of the article and the second direction (Y) along the width direction of the article, and the laminated first piece (1) and the second piece (2) are partially joined to form a plurality of joint parts, the first The sheet (1) protrudes in a direction away from the second sheet (2) at parts other than the joint portion to form convex portions protruding toward the wearer's skin side, and the composite sheet (10) has convex portions formed in mutually different patterns. A central region (M) and a pair of side regions (S, S), the area ratio of the joint in the side region (S) is higher than the area ratio of the joint in the central region (M), and the central region (M ) has the same height as the largest convex portion in the side region (S).

Description

technical field [0001] The present invention relates to absorbent articles such as disposable diapers, sanitary napkins, and incontinence pads. Background technique [0002] In the prior art, as a front sheet of absorbent articles such as disposable diapers, sanitary napkins, and incontinence pads, it is known that unevenness is formed on the skin side facing the wearer's skin side by embossing or the like. shaped slices. In addition, there is also known a technique for improving the leak-proof effect of loose stools and urine by forming unevenness on the skin-side surface of the front sheet (Patent Documents 1 and 2). [0003] However, when the absorber is thinned in order to improve the fit when worn, or the rigidity of the absorber is reduced by opening a part of the absorber, the front sheet positioned at the crotch portion tends to wrinkle, and the front sheet The anti-leakage effect due to the concave-convex shape is reduced, and soft stool or urine tends to flow alo...
