Absorbent article

Abstract

Well-fitting three-dimensional gathers which match different body shapes are formed by three-dimensional gathers in a left and a right set which have different cross-sectional shapes in each of the fluid discharge region and the back end region. Three-dimensional gathers (BS) are provided, wherein a sheet extending from the side to the center is folded in four by a second folded-back section (33)and a third folded-back section (34) from a first folded-back section (32) which is folded back to the side at the center position, and the sheet has a first folded-back surface (35), a second folded-back surface (36), a third folded-back surface (37), and a fourth folded-back surface (38) from the lower layer side. In the specified lengthwise direction range which includes the body fluid discharge region (H) of an absorbent article, at least the third folded-back surface (37) and the fourth folded-back surface (38) stand with a roughly ''<''-shaped cross-section, and are connected to each other from the second folded-back surface (36) up to the fourth folded-back surface (38) in the back end region, standing in an inclined line shape with the first folded-back section (32) as the standing point.

Description

technical field [0001] The present invention mainly relates to absorbent articles such as sanitary napkins, sanitary pads, leucorrhea pads, incontinence pads, cosmetics, etc., and specifically relates to three-dimensional pleats formed on both sides of the surface side of the absorbent articles. structure. Background technique [0002] Conventionally, as absorbent articles such as sanitary napkins, sanitary pads, and incontinence pads, liquid-impermeable back sheets such as polyethylene sheets or polyethylene laminated non-woven fabrics and non-woven fabrics or liquid-permeable plastics have been known. An absorbent article in which an absorbent body made of cotton-like pulp or the like is interposed between a liquid-permeable top sheet such as a sheet. [0003] In such an absorbent article, in order to prevent excreted bodily fluids from leaking from the crotch portion, three-dimensional gathers are formed that rise toward the surface side in various forms along the longit...

AI Technical Summary

Problems solved by technology

[0004] However, the three-dimensional pleats shown in the above-mentioned Patent Documents 1 to 4 are formed on both sides corresponding to the body fluid discharge site, but there is a problem that, for example, when the body fluid is discharged when sleeping , and in the presence of fluids that leak laterally in the form of temporary flow to the buttock side and then spread laterally, do not hold these fluids well
