Abstract

<P>PROBLEM TO BE SOLVED: To provide a sanitary napkin preventing leakage to an underwear due to an extension to the buttock portion when discharging and uncomfortable feeling and having easiness in carrying the same. <P>SOLUTION: A body liquid absorber such as the sanitary napkin is a planar body constituted by applying an adhesive for securing on the back face of the body of the same that is an underwear side and affixing a removing material on the adhesive. An optionally shaped hole is bored in the center portion of the affixed removing material and filled with a removing material of the same shape and affixed, the buried and affixed removing material is removed when using, the exposed adhesive face is fold into two to adhere and returned to an original shape, when the back face turns planar to get the front face projected to show a shape enough to stick fast to a body. Further an absorbing portion is exposed also in the exposed adhesive face of the body liquid absorber and can be piled at the same time, so that body liquid can be more uniformly absorbed. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

The present invention relates to a body fluid absorber such as a sanitary napkin, and more specifically, a sanitary napkin that can be tightly attached to the body by three-dimensionalization, and can prevent leakage to underwear and thereby further reduce discomfort. This relates to a body fluid absorber.

In general, a body fluid absorber such as a sanitary napkin is configured by interposing a liquid absorbing material between a liquid permeable top sheet and a non-liquid permeable back sheet. Since body fluid such as discharged blood spreads through the buttocks, the underwear may be soiled depending on the amount of bleeding and posture. Therefore, in recent years, in body fluid absorbers such as sanitary napkins, in order to deal with the above spreading of body fluids such as discharged blood, technology for increasing the absorption capacity of the absorber, technology for expanding the contact area with the body, Various techniques for providing gathers that easily follow the surroundings, or a technique for forming a pants form have been proposed.

In addition, in the body fluid absorber such as a sanitary napkin, an “auxiliary absorber” that is disposed on the absorption surface of the body fluid absorber such as a sanitary napkin or sandwiched between the discharge portions is also proposed. ing.

Problems to be solved by the invention

The conventional body fluid absorbers and auxiliary absorbers such as sanitary napkins as described above deal with this on the premise of spreading to the buttocks at the time of discharge, or those using two different absorbers are portable surfaces It lacks in convenience.
The present invention has been made in view of such circumstances, and the purpose thereof is to make it possible to reliably prevent leakage to underwear by three-dimensionalization during use, and to reduce discomfort and maintain portability. The object is to provide a body fluid absorber such as a novel sanitary napkin.

Means for solving the problem

The present invention is based on an idea completely different from the concept of a body fluid absorber such as a conventional sanitary napkin that absorbs body fluid such as blood that has been discharged and spread, and as a result of examining fundamental measures, Obtained knowledge.
That is, an adhesive material is applied to the back surface of the absorbent body in order to adhere to the undergarment, and a release material is affixed, the gist of which is the shape of the release material affixed to the adhesive surface. In other words, in order to expose the adhesive surface having a shape that forms a protruding convex part on the absorption surface at the center of the release material, a cut or release material is laminated and pasted so that only this exposed surface can be easily removed before mounting. Keep it.
The release material is peeled off, the adhesive surfaces are exposed, the adhesive surfaces are folded and bonded together, and then returned to a solid shape with a flat back surface and a protruding convex portion on the surface.

The invention's effect

If a body fluid absorber such as a sanitary napkin is attached so that this convex part is sandwiched between the discharge places, it is possible to prevent the spread of body fluids such as blood, urine, secretions, etc. Prevention of leakage and further reduction in discomfort.

Examples of the implementation of the invention

An embodiment of a body fluid absorber such as a sanitary napkin according to the present invention will be described with reference to the drawings.
FIG. 2 is a perspective view showing one embodiment of a body fluid absorber such as a sanitary napkin according to the present invention. In the following description of the embodiment, a body fluid absorber such as a sanitary napkin is abbreviated as “absorber”.

As shown in FIG. 2, the absorbent body of the present invention comprises an absorbent body (1) and a release paper (2) attached to the back surface.

The absorbent body (1) is the same as the conventional absorbent body, basically the absorbent surface (3), the absorbent portion (1a), the opposite adhesive surface “back surface” (4) and the release material (2). Consists of. The absorption surface (3) is a liquid-permeable sheet on the side in contact with the body. The pressure-sensitive adhesive surface “back surface” (4) is a liquid-proof sheet on the side in contact with clothing, and is coated with an adhesive material on the outside. The adhesive material coating layer on the outer surface of the adhesive surface “back surface” (4) is covered with the release paper (2) until use.

As shown in FIG. 1, the release paper (2) has a cut line “cut along the line” (5). As shown in FIG. 4, the adhesive surface (4a) exposed by peeling off before use is obtained.

When the above-mentioned exposed adhesive surface (4a) is folded in half as shown in FIG. 6 along the longitudinal center line AA, the adhesive surfaces (4a) are adhered to each other and then returned to the original state as shown in FIG. Absorption part "convex part" (7) is formed.

If said operation is performed, the absorber main body before use for a body will become like FIG. 8 which is a perspective view.
The absorption surface “surface” (3) has the absorption portion “convex portion” (7). When the release material (2) remaining on the adhesive surface “back” (4) is peeled off and the absorbent part “convex part” 7) is attached to the body fluid outlet such as the entrance of the vagina, Fits in the discharge area.

When the adhesive surface (4a) exposed as shown in FIG. 4a is further formed with a hole to form the exposed absorbent body (8), the area of the adhesive portion (6) of the absorbent portion “convex portion” (7) , And the absorption parts (1a) are in close contact with each other, so that the body fluid can be more evenly absorbed.

It is a back view (1) which shows one form of the absorber which concerns on this invention. It is a perspective view which shows one form of the absorber which concerns on this invention. It is sectional drawing which shows one form of the absorber which concerns on this invention It is a back view (2) which shows one form of the absorber which concerns on this invention. It is sectional drawing of [FIG. 4] which shows one form of the absorber which concerns on this invention. It is BB sectional drawing folded in half by AA of [FIG. 4] which shows one form of the absorber which concerns on this invention. FIG. 5 is a cross-sectional view taken along line B-B after being folded in half at A-A in FIG. 4 showing an embodiment of the absorbent body according to the present invention. It is a perspective view before mounting | wearing with the one form of the absorber which concerns on this invention. It is a back view (3) which shows one form of the absorber which concerns on this invention.
