Problems solved by technology

[0004] However, in the absorbent article described in Japanese Patent Application Laid-Open No. 11-358, since there are no grooves at all in the first pulp layer of the absorbent body, the rigidity distribution of the absorbent article is actually poor, and it is easy to generate a gap. Deformation of the ends of the absorbent article caused by curling in the first pulp layer

Embodiment Construction

[0019] Hereinafter, the present invention will be described using the drawings, but the present invention is not limited to the forms shown in the drawings.

[0020] figure 1 It is a plan view of one embodiment of the absorbent article of the present invention. figure 2 It is its Y-Y' sectional view. image 3 It is a plan view of a preferable embodiment of the absorbent article of the present invention.

[0021] The absorbent article 1 of the present invention is composed of at least a liquid-permeable sheet 7 , a liquid-impermeable sheet 10 and an absorbent body 2 . The absorber is usually integrated with the backing paper 6 , and the integrated absorber is sandwiched between the liquid-permeable sheet 7 and the liquid-impermeable sheet 10 . Such as figure 1 As shown, the absorber is composed of a first absorbing part 3 and a second absorbing part 4, the area of ​​the second absorbing part is smaller than that of the first absorbing part, and the second absorbing part is...

Abstract

Provided are an absorptive article less deformable at ends thereof, snugly fitting on a wearer, and highly absorptive, and a method of producing the absorptive article. An absorptive article having at least a liquid-permeable sheet, a liquid-impermeable sheet, an absorbing body sandwiched between the liquid-permeable sheet and the liquid-impermeable sheet. The absorbing body comprises a first absorbing section and a second absorbing section which is formed substantially at the center of the first absorbing body and has a smaller area than the first absorbing section. Pressed grooves are continuously formed in a substantially closed shape so as to extend from peripheral edge regions in the longitudinal direction of the second absorbing section to the first absorbing section.

Description

technical field [0001] The present invention relates to absorbent articles. In particular, it relates to absorbent articles such as sanitary napkins and incontinence sheets provided with squeezed strip-shaped grooves at specific positions of the absorbent body. Background technique [0002] In the past, the absorbent body for absorbent articles such as sanitary napkins was simply laminated with pulp fibers, so when used, there was a problem that the absorbent article became flat, or the fit was reduced, and the absorption performance was low. . [0003] As an absorbent article that solves this problem, an absorbent article is known in Japanese Patent Application Laid-Open No. 11-358, which consists of a first pulp layer and a second pulp layer laminated thereon and having a smaller area than the first pulp layer. Pulp layer structure, on the second pulp layer, in the peripheral region, a specific groove portion is formed, through the formation of the groove portion, the ab...
