Problems solved by technology

In addition, once the liner is forced into the liner so that the central axis of the liner in the longitudinal direction is along the vaginal opening or the vestibular floor, the liner with uniform rigidity in the length direction will buckle irregularly, and the tightness with the inner wall of the labia Lowered, not only is the liner at risk of detaching from the labia, but there is a risk of overstimulation of the labia

[0055] First Embodiment: Cutout

[0056] [Overall composition of the interlabial pad]

[0057] figure 2 It is a perspective view showing the interlabial pad 11 of the first embodiment folded in half. The interlabial pad 11 of this embodiment has a center axis Q extending along the center line in the longitudinal direction X. As shown in FIG. The liner 11 is folded in half with the central axis Q as the crease line, at least a part near the central axis Q is in contact with the vestibular floor in the labia, and at least a part is sandwiched by the labia minora between the labia. In addition, the back portion of the pad 11, which is located on the rear side of the user and preferentially comes into contact with the user's body during use, has a low compression rigidity structure at the rear portion, which is lower in compression rigidity than the front portion located on the front side, Therefore, there is a low compressive rigidity portion 21 at the rear portion of the pad...

[0100] Second Embodiment: Embossing

[0101] The interlabial pad in the second embodiment will be described. In 2nd Embodiment, the embossing 7 is provided in the absorber 32 as a "rear part low compression rigidity structure." In the second embodiment, embossing 7 is provided to increase the rigidity of the embossed area, and the embossed area is used as a bending starting point to preferentially compress only the rear part of the pad.

[0102] [rear part low compression rigidity structure]

[0103] Figure 7 It is a plan view showing the absorber 32 of the interlabial pad of the second embodiment. In 2nd Embodiment, one row of embossing 7 is provided discontinuously in the direction perpendicular|vertical to the central axis Q. As shown in FIG. and, Figure 8 In order to explain the effect of the embossing 7 of the interlabial pad of the second embodiment, a state view when pressure is applied in a vertical direction to the absorbent core 32 folded in half is seen from ...

[0110] Third Embodiment: Areas with Low Weight per Unit Area

[0111] The interlabial pad of the third embodiment will be described. In the third embodiment, an absorber in which the basis weights of the front portion and the rear portion are changed is used as the “rear portion low compression rigidity structure”. In the third embodiment, by changing the basis weight between the front portion and the rear portion of the absorber of the pad to form a starting point of bending, only the rear portion of the pad can be preferentially compressed.

[0112] [rear part low compression rigidity structure]

[0113] Figure 10It is a figure which shows the absorber 34 of the interlabial pad of 3rd Embodiment. In the third embodiment, a region 8 having a lower basis weight than the peripheral region is provided in a region straddling the central axis Q of the rear portion. In the area 8, the compressive rigidity in the vertical direction to the user is lower than that of the surround...

Abstract

An interlabial pad fits a vaginal opening and a vestibule floor without a gap with the vaginal opening or the vestibule floor. The pad prevents leakage of menstrual blood from a gap and prevents dropping out of the pad when the pad is worn between labia. The interlabial pad is provided with an absorbent body for absorbing and holding body fluid, has a central axis, and is worn with at least one portion held by labia minora, between the labia, so that at least one portion close to the central axis when worn touches the vestibule floor inside the labia of the wearer, and is also provided with a rear portion low compression rigidity structure, so that a rear portion that is positioned to the rear of the wearer and, when worn, touches the body of the wearer first, has low compression rigidity in comparison to a front portion positioned to the front.

Description

[0001] This application claims the benefit of priority based on Japanese Patent Application No. 2005-061645 filed on March 4, 2005, the contents of which are incorporated herein by reference. technical field [0002] The present invention relates to that when the user installs the liner between the labia, the liner can be placed along the vaginal opening or the vestibule floor without creating a gap between the liner and the vaginal opening or the vestibule floor, which can prevent menstrual blood from leaking from the gap or a detached interlabial pad. Background technique [0003] Conventionally, sanitary napkins and tampons are generally used as sanitary products for women. Many efforts have been made to prevent sanitary napkins from leaking menstrual blood from gaps due to lack of tightness around the vaginal opening. In addition, the tampon has a foreign body feeling or uncomfortable feeling during use due to the properties of the article, and difficulty in inserting i...
