Absorptive article and method of producing the same

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...

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
