Problems solved by technology

[0009] Since their leak-proof walls are elastically shaped themselves, the rigidity of the leak-proof walls themselves is low. For example, when standing up from the surface of an absorbent article, the buckling strength of the leak-proof walls themselves cannot be greatly improved. high
Therefore, when forming a three-dimensional leak-proof wall, it is difficult to maintain the above-mentioned three-dimensional shape.

Embodiment Construction

[0037] figure 1 To show a perspective view of a sanitary napkin as an example of the absorbent article of the present invention, figure 2 for figure 1 The II-II line cross-sectional view, image 3 for figure 1 A partial enlarged view of , Figure 4 is figure 1 The IV-IV line cross-sectional view, Figure 5 for figure 1 The V-V line sectional view.

[0038] The X direction of the absorbent article 1 shown in the figure is the width direction, and the Y direction is the longitudinal direction. The intermediate region in the longitudinal direction is the center portion 2 , and the region sandwiching the center portion 2 is the front portion 3 and the rear portion 4 . Leak-proof walls 5 and 5 extending in the longitudinal (Y) direction are provided at both ends in the width direction of the absorbent article 1 . The leak-proof walls 5 and 5 can exert a longitudinal elastic shrinkage force, and the absorbent article 1 can be bent in the longitudinal direction (Y direction) ...

Abstract

The leak-proof walls 5 disposed on both sides in the transverse direction of the absorptive article have side wall parts 15 rising from a front surface 2a and skin contact parts 16 abutting on the skin. The side wall parts 15 are provided with folded guide parts 17. The folded guide parts 17 are therefore directed toward an outer side and the side wall parts 15 are folded when the skin contact parts 16 are pressed. Consequently, the skin contact parts 16 do not fall largely to the absorptive core 12 side and do not lower a liquid receiving area.

Description

technical field [0001] The present invention relates to absorbent articles such as sanitary napkins and disposable diapers, and particularly to absorbent articles provided with leak-proof walls on both sides in the width direction of the surface. Background technique [0002] Absorbent articles such as sanitary napkins and disposable diapers are provided with longitudinally extending leak-proof walls on both sides of the surface in the width direction. [0003] For example, Japanese Patent Application Laid-Open No. 8-21524 discloses an absorbent article using, as the above-mentioned leakage preventing wall, a standing sheet deformed into a non-planar shape by machining. The leak-proof wall formed of the above-mentioned standing sheet functions as a band-shaped elastic sheet which exerts elastic contraction force in the longitudinal direction of the absorbent article. [0004] In Japanese Patent Publication No. Hei 9-503934, elastic gathers are attached to both sides in the ...
