Abstract

An object of the present invention is to provide an interlabial pad, with which a wearer will hardly feel a sensation of using the interlabial pad, even when a wearer moves and pressure from the exterior is applied to the interlabial pad. An interlabial pad 10, with which a wearer will hardly feel a sensation of using the interlabial pad, can be provided by equipping a crease-spanning region 2 of the interlabial pad 10 with a pressure dispersion means 11, which, in repulsion to pressures that are applied from the vestibular floor to the crease-spanning region 2 of the interlabial pad 10 in accompaniment to movements of the wearer, prevents the direct transmission of the pressures to the vestibular floor.

Claims

1. An interlabial pad, comprising, in a fitted state:

a body side face facing a body side; and

an opposite body side face facing the side opposite to the body side face; and

being formed to a practically longitudinal shape having a longitudinal direction and a lateral direction;

wherein

the interlabial pad is fitted by being folded in two so that the opposite body side face faces itself in the lateral direction, and held between the labia in a state in which at least a part of a portion along a crease as a folding axis formed by being folded in two contacts the vestibular floor in the labia; and

wherein

the interlabial pad is equipped, at a crease-spanning region spanning the crease, with a pressure dispersion means which, in response to a pressure that is applied to the interlabial pad when a wearer moves, prevents the pressure from being directly transmitted to the vestibular floor.

2. The interlabial pad according to claim 1, wherein the interlabial pad has a fiber aggregate equipped at the crease-spanning region, and wherein

the pressure dispersion means has fibers oriented so as to cross the crease in order to control the property of repulsion against the pressure.

3. The interlabial pad according to claim 1, wherein the pressure dispersion means has a slit formed at the crease-spanning region.

4. The interlabial pad according to claim 2, wherein the pressure dispersion means has a slit formed at the crease-spanning region.

5. The interlabial pad according to claim 1, wherein the pressure dispersion means has an embossing pattern formed at the crease-spanning region.

6. The interlabial pad according to claim 2, wherein the pressure dispersion means has an embossing pattern formed at the crease-spanning region.

7. The interlabial pad according to claim 1, wherein the interlabial pad is equipped with a liquid-impermeable, elastic sheet at the opposite body side face, and wherein

the pressure dispersion means is provided in the elastic sheet.

8. The interlabial pad according to claim 1, wherein the interlabial pad has a mini sheet piece, with elasticity, attached to the opposite body side face, and wherein

the pressure dispersion means is provided in the mini sheet piece.

9. The interlabial pad according to claim 8, wherein entirety of one face of the mini sheet piece is joined to the opposite body side face.

10. The interlabial pad according to claim 8, wherein the mini sheet piece is joined to the opposite body side face, which is faced with itself across the crease so that a space is formed between the opposite body side face and the mini sheet piece so as to restrict the separation of the facing opposite body side face from each other in the state of being folded in two.

11. The interlabial pad according to claim 1, wherein the respective side ends in the longitudinal direction are bent towards the body side face so as to reduce the pressures applied to the interlabial pad when the wearer moves, and wherein

flexible lines that serve as axes of the bending are provided at the respective side ends in the longitudinal direction.

12. The interlabial pad according to claim 1, wherein the interlabial pad is an interlabial pad for urinary incontinence.

13. The interlabial pad according to claim 1, wherein the interlabial pad is an interlabial pad for absorbing vaginal discharge.

14. An interlabial pad wrapping body, in which the interlabial pad according to claim 1 is enclosed and sealed in an individual wrapping container.
