Problems solved by technology

When the wearer is in a supine position with the convex portion reinforced by the hard member facing the buttock cleft, the hard member is likely to come into contact with the shallow groove of the buttocks, causing discomfort and making it impossible to sleep comfortably.
[0015] The structure of the protrusions of the menstrual napkin described in Patent Document 4 is not clear, but the protrusions have a triangular cross-section, and like Patent Documents 1 and 2, it is difficult to stick to the buttock cleft.

Embodiment Construction

[0049] figure 1 In order to show the perspective view of the sanitary napkin of the first embodiment of the present invention, figure 2 It is the longitudinal sectional view of the above-mentioned menstrual sanitary napkin 1, and Fig. 3 is figure 1 A cross-sectional view of line III-III of the shown menstrual napkin.

[0050] There are two main surfaces in the sanitary napkin and its parts, the surface facing the crotch of the wearer is called "skin side surface", and the opposite surface is called "clothing side surface". In addition, the longitudinal direction of the sanitary napkin is referred to as "longitudinal direction", and the direction perpendicular to the above-mentioned longitudinal direction is referred to as "horizontal direction". Unless otherwise specified, the dimensions of each part are referred to as "length dimensions" in the longitudinal direction, and as "width dimensions" in the transverse direction.

Abstract

A napkin (1) for physiology comprises a napkin body (2) having a liquid absorbing layer (22). A three-dimensional structural part (3) is formed on the skin side surface of the napkin body (2). The three-dimensional structural part (3) is formed of an airlaid nonwoven fabric and a liquid permeable sheet, and compression parts (37) extending upward are formed on the airlaid nonwoven fabric. The three-dimensional structural part (3) is fitted to the groove of a human body to effectively prevent the menstrual blood from leaking rearward in sleeping. Thus, the slender napkin for physiology disposed between a vaginal opening and an anal cleft part capable of improving a function for preventing menstrual blood from leaking rearward by fitting it to the anal cleft part.

Description

technical field [0001] The present invention relates to a lengthwise menstrual napkin having a vagina facing portion and a gluteal cleft facing portion extending toward the back, and more particularly to such a menstrual sanitary napkin which can be closely attached to the body. The anus extends to the hip cleft in the rear, and following the deformation of the hip cleft, it exerts the effect of preventing menstrual blood from leaking backward while sleeping. Background technique [0002] Among the conventional sanitary napkins, there is a sanitary napkin in which a convex structure for closely contacting the wearer's body is provided on the skin-side surface of a sanitary napkin main body having a liquid absorbing layer. [0003] The following Patent Document 1 discloses a sanitary napkin having a first absorbent member having a triangular cross-section. The first absorbent member has an absorbent core that absorbs and holds liquid, and a covering member that covers the ou...
