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

This absorbent article (1) is provided with: a front surface sheet (12) comprising a composite sheet; a rear surface sheet (13); and an absorbent (14) disposed between both of the sheets. The composite sheet (10) has a first direction (X) in the lengthwise direction of the article and a second direction (Y) in the widthwise direction of the article, and is provided with a plurality of coupling sections that partially couple a first sheet (1) and a second sheet (2) that are laminated, the first sheet (1) being provided with protrusions that protrude in the direction away from the second sheet (2) in locations other than the coupling sections and protrude toward the skin of a wearer. The composite sheet (10) has a middle region (M) and a pair of side regions (S, S) in which the protrusions are formed in different patterns, the surface area ratio of the coupling sections in the side regions (S) is greater than the surface area ratio of the coupling sections in the middle region (M), and the height of the middle region (M) and the side regions (S) is the same as the maximum height of the protrusions.

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...
