Embodiment Construction

[0030] The present invention is described below with reference to the accompanying drawings, figure 1 It is a partially cutaway view showing a sanitary napkin as a first embodiment of the absorbent article of the present invention from the liquid receiving side. figure 2 yes figure 1 A cross-sectional view of line II-II of the shown sanitary napkin. image 3 yes figure 1 Sectional view of line III-III. Figure 4 yes figure 1 Sectional view of line IV-IV. The X direction in the figure is the width direction, the Y direction is the vertical direction, the Z1 direction is the upper direction on the excretory part side (liquid receiving side), and the Z2 direction is the lower direction on the outer attachment body side such as underwear.

[0031] figure 1 The shown sanitary napkin 1 is mainly composed of a support body 2 facing an external body such as underwear, and a liquid absorption member 3 located on the wearer's side for absorbing excrement. Side wall layers 4 , 4 ...

Abstract

The object of the present invention is that it is not easy for the traditional sanitary napkin to follow the movement of the wearer and keep blocking / close contacting the excretory organ, and thus the excrement liquid can not be completely absorbed. The solution of the present invention is that side wall sheets 4, 4 extended in the longitudinal direction are disposed on two ends of a support body 2 in the widthwise direction. The side wall sheets 4, 4 are distorted into sawtooth-like in the perpendicular direction, and has elastic contraction force in the longitudinal direction, whereby the side wall sheets 4, 4 is erected on the support body 2. A liquid absorbing member 3 is supported by the side wall sheets 4, 4. Therefore, the liquid absorbing member 3 is movable over the support body 2 independently, following the movement of the wearer and keeps close contacting the human body.

Description

technical field [0001] The present invention mainly relates to an absorbent article for absorbing and retaining excrement fluid such as menstrual blood, and more particularly to an absorbent article capable of efficiently absorbing excretion fluid following the movement of a user. Background technique [0002] Conventionally, various absorbent articles such as sanitary napkins, panty liners, changing pads, and diapers have been developed. In these absorbent articles, it is desired that the absorbent core reliably absorb excrement fluid during use so that the excretion fluid does not leak out of the absorbent article. [0003] However, the shape of the body around the excretory part, especially around the vaginal opening, is different in the wearer's standing state, sitting state, closed leg state, and open leg state. Its shape changes moment by moment while walking. Especially when walking, the flesh of the left and right buttocks is displaced to the left, right, up, down,...
