Abstract

(57) [Abstract] [Problem] To provide a disposable diaper having excellent adhesion to a wearer. SOLUTION: The disposable diaper is characterized in that a pair of embossed lines provided on both sides in the longitudinal direction of the absorbent body are convexly curved inward so as to face each other at the central portion in the longitudinal direction.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a disposable diaper, which has excellent adhesion to the body.

[0002]

[Problems to be solved by conventional techniques and devices]

 BACKGROUND ART Conventionally, disposable diapers have been formed into a pants type or a developed type by sandwiching an absorbent body located at the crotch part when worn with a liquid-permeable top sheet and a liquid-impermeable back sheet. The absorbent used in such a diaper has the following structure in order to improve its absorption performance. That is, as shown in Japanese Utility Model Publication No. 61-78810, a short emboss (2) oriented in the longitudinal direction of the absorber (1) is uniformly provided on the surface of the absorber (FIG. 4), As disclosed in Japanese Utility Model Laid-Open No. 63-27405, the absorbent body (1) is provided with a linear embossment (3) and an oblique embossment (4) in the longitudinal direction (FIG. 5). .

Although the absorber provided with such an emboss certainly improves the absorption speed, it is not satisfactory in terms of fit when worn. Therefore, as disclosed in Japanese Patent Application Laid-Open No. 1-162801, a material has been developed which can be easily deformed into the shape of a crotch when the absorbent body is formed with embossed patterns and worn. However, if the embossing is complicatedly formed in this way, the texture of the absorbent body is insufficient, and the absorbent body becomes hard and uncomfortable to wear.

[0004]

[Means for Solving the Problems]

 As a result of studies in view of this, the present invention has developed a disposable diaper that has excellent adhesion when worn but does not impair the texture.

That is, one of the disposable diapers of the present invention is a disposable diaper in which an absorbent body is interposed between a liquid-permeable top sheet and a liquid-impermeable back sheet, and both side portions in the longitudinal direction of the absorbent body. A pair of embossing lines provided on the absorbent body are convexly curved inward at the central portion in the longitudinal direction, and another one of the present inventions is a disposable diaper. A pair of embossed lines are provided on both sides of the absorbent body along both sides in the longitudinal direction of the absorbent body in which both side edges of the longitudinal direction of the absorbent body are convexly curved inward. It is characterized by.

【Example】

 (Example 1) As shown in FIG. 1, a pair of embossed lines (5) (5) having central portions opposed to each other and curved in a convex shape inwardly are provided on both sides in the longitudinal direction of the absorber (1). Provided. A disposable diaper in which the absorbent body (1) provided with such an embossing line is fixed by sandwiching it with a liquid-permeable sheet and a liquid-impermeable sheet, has good adhesion to the crotch part, and liquid absorption follows the embossed line. It was also excellent in diffusivity in the longitudinal direction. For embossing, embossing simply by embossing with pressure, embossing using heat, embossing combining with an adhesive, etc. can be used. At this time, the embossed concave groove (6) is provided on the absorbent body (1) itself as shown in FIG. 2, and such an absorbent body (1) is impermeable to the liquid-permeable top sheet (7) and the liquid-permeable top sheet (7). The structure is sandwiched between the back sheet (8). With such a structure, the surface of the disposable diaper that comes into contact with the skin has no irregularities, and the touch is good and the wearing feeling is good.

Example 2 As shown in FIG. 3, an absorber (1 ′) having a constricted shape in which both side edges of a central portion in the longitudinal direction along the shape of a crotch portion are convexly curved inward to face each other. In the above, a pair of embossed lines (5) and (5) were provided along the shape of both side edges of the absorbent body (1 ′), with the central portions in the longitudinal direction facing each other and convexly curved inward. Disposable diapers such as pants-type diapers using such an absorber were excellent in adhesion to the crotch and liquid absorbency.

[0008]

As described above, according to the present invention, the adhesion of the disposable diaper for babies, adults and the elderly of the present invention to the crotch part during and during wearing is improved and the texture is not impaired. In addition, since it has a good feel to the touch and is excellent in wearability, it has the effects of being comfortable to wear and reducing urine leakage.
