Problems solved by technology

In the absorbent article described in this document, not only wrinkles are easily generated due to the formation of squeeze grooves, but also wrinkles are likely to be generated due to the formation of recesses in the front sheet.
The reason is that when the absorbent article is worn, the concave portion acts as a flexible shaft for deformation, so that deep wrinkles are likely to occur.

Embodiment Construction

[0020] Hereinafter, the absorbent article of the present invention will be described based on a sanitary napkin as a preferred embodiment thereof with reference to the drawings. Such as figure 1 with figure 2 As shown, the sanitary napkin 1 of this embodiment has an absorbent main body 5, and has a longitudinal direction X corresponding to the wearer's front-back direction and a transverse direction Y perpendicular thereto. The absorbent main body 5 has a liquid-retaining absorbent body 4, The front sheet 2 arranged on the skin facing side of the absorber 4 and the back sheet 3 arranged on the non-skin facing side of the absorber 4 .

[0021] In addition, in this specification, the skin-facing surface is the surface facing the wearer's skin side when the absorbent article is worn, and the non-skin-facing surface is the absorbent article or its constituent parts (for example, the absorbent main body 5). The surface of the component member facing the side opposite to the skin...

Abstract

An absorption body (4) has, in the excretory part-facing section (B) thereof, an excretory part slit region (S) in which longitudinal slits (43) extending in the longitudinal direction (X) are formed dispersedly. A front surface sheet (2) has, on the skin-facing surface (2a) side thereof, protrusions (21) and recesses (20), each of the recesses (20) being located between adjacent protrusions (21). In a plan view of an absorptive article (1), the longitudinal slits (43) in the absorption body (4) and the recesses (20) in the front surface sheet (2) intersect. The recesses (20) have a greater width than the longitudinal slits (43).

Description

technical field [0001] The present invention relates to absorbent articles such as sanitary napkins. Background technique [0002] In absorbent articles such as sanitary napkins, the following technology is known: for the purpose of improving the fit of the article to the wearer's body and guiding the excreted liquid in a predetermined direction, the front sheet and the absorbent body are formed integrally. Extrusion groove formed by ground extrusion. When the topsheet and the absorber are integrally pressed from the topsheet side, wrinkles tend to appear in the vicinity of the squeeze grooves because the topsheet of the flat material is stretched unevenly. For the purpose of preventing the generation of the wrinkles, for example, Patent Document 1 proposes that when forming an embossed concave portion that sinks from the top sheet into the absorber, a slit or a punching hole is formed near the bottom of the embossed concave portion to make the embossed concave portion The...
