Problems solved by technology

[0003] However, in these absorbent articles, since the low-compression portion is formed over substantially the entire area of ​​the compressed groove, there is a possibility that the body fluid in contact with the groove may spread to the front and rear ends of the groove.
For this reason, the high-compression part and the low-compression part in contact with body fluids will be wetted, and the bonding force between the constituent layers of the absorbent article will be weakened. Not only will wrinkles caused by movement be induced, but also the bond between the slurry as the constituent material of the absorbent body will be weakened. also detach, reducing the rigidity of the absorbent article
On the other hand, since the rigidity becomes higher in the part that does not come into contact with body fluids, it does not adhere to the body during wearing, causing discomfort.

Embodiment Construction

[0020] Hereinafter, one preferred embodiment (first embodiment) of the absorbent article of the present invention will be described with reference to the drawings.

[0021] The absorbent article 1 of the first embodiment, such as figure 1 As shown, it is composed of at least a liquid-permeable sheet 2, a liquid-impermeable sheet 3, and an absorbent body 4 sandwiched between the liquid-permeable sheet and the liquid-impermeable sheet.

[0022] In the first embodiment, the left and right compressed strip-shaped grooves 7a, 7b located at the side edges in the longitudinal direction of the central region 5 of the absorbent body are formed on the side of the skin contacting surface of the absorbent article, and the longitudinal front portions of the side edges are formed. The front compression bar-shaped groove 7c, and the rear part compression bar-shaped groove 7d located at the rear part of the length direction of the side edge. Furthermore, in order to surround the central regi...

Abstract

Disclosed is an absorbent article wherein a body fluid which has come into contact with a compressed groove is prevented from spreading to the edge of the compressed groove, and deformation of the absorbent article due to contact with the body fluid is prevented. The absorbent article comprises at least a fluid-permeable sheet, a fluid-impermeable sheet, and an absorber which is sandwiched between said fluid-permeable sheet and said fluid-impermeable sheet; and a pair of compressed grooves which integrate from the fluid-permeable sheet through the absorber are formed on the skin contact surface side of said absorbent article along the length direction. In the absorbent article, the compressed groove is comprised of a high-compression section and a low-compression section; said high-compression section is composed of quasi-traversing high-compression sections, which are formed to almost run across the compression groove in the width direction and disposed at a distance from each other in the length direction of the compressed groove, and non-traversing high-compression sections, which are formed not to run across the compressed groove and disposed at a distance from each other between said quasi-traversing high-compression sections; and said low-compression section is formed so as to continue in the length direction of the compressed groove between said quasi-traversing high-compression sections due to the arrangement of said non-traversing high-compression sections.

Description

technical field [0001] The present invention relates to absorbent articles used in sanitary napkins, panty liners, incontinence pads, etc., which do not spread body fluids and have deformation stability of the absorbent article when wet. Background technique [0002] Japanese Patent Laying-Open No. 2004-321393 discloses an absorbent article that has a strip-shaped groove on the skin contact surface side, and the strip-shaped groove is composed of a high-compression portion and a low-compression portion. The groove side edges are formed so that positions in the longitudinal direction of the linear grooves are shifted from each other, and the low compression portion is continuous in the longitudinal direction of the linear grooves. Also, for example, JP-A-2003-265518, JP-A-2003-38555, etc. disclose absorbent articles having strip-shaped grooves of the same structure. In the linear groove having such a structure, the low compression portion is continuously formed in the longit...
