AI Technical Summary

Problems solved by technology

Since the conveyance of the absorbent core is carried out at high speed, the rigidity of the absorbent core is reduced by narrowing the range where the core pressing part is provided, and the absorbent core may be curled or twisted during conveyance, and the absorbent core may not be conveyed properly.

Embodiment Construction

[0015] (1) Outline of Embodiment

[0016] From the description of this specification and the drawings, at least the following matters are clarified.

[0017] An absorbent article according to one aspect has: a longitudinal direction and a width direction perpendicular to each other; an absorbent core having an absorbent material; into the core extrusion section. The core crushed region has a first crushed region arranged at one end of the absorbent core in the longitudinal direction and a first crushed region arranged at the other end of the absorbent core in the longitudinal direction. Second squeeze area. A non-extruded area in which the core extruded portion is not provided is provided between the first extruded area and the second extruded area. A shape of an inner end side in the length direction of the first crushed region is different from a shape of an inner end side in the length direction of the second crushed region. According to this aspect, the rigidity of the...

Abstract

The invention provides an absorbent article which can suppress reduction of wearing feeling caused by rigidity of an absorbent core and can properly convey the absorbent core. The absorbent article has: a longitudinal direction and a width direction which are orthogonal to each other; an absorbent core (30) having an absorbent material; and a core pressing region in which at least a core pressing part (85) formed by compressing the absorbent core in the thickness direction is provided. The core pressing region has a first pressing region (31) disposed at one end of the absorbent core in the longitudinal direction, and a second pressing region (32) disposed at the other end of the absorbent core in the longitudinal direction. A non-extrusion region (35) in which the core extrusion part is not provided is provided between the first extrusion region and the second extrusion region. The shape of the inner end edge (31S) in the longitudinal direction of the first extruded region is different from the shape of the inner end edge (32S) in the longitudinal direction of the second extruded region.

Description

technical field [0001] The present invention relates to an absorbent article provided with a core squeeze portion in an absorbent core. Background technique [0002] Patent Document 1 discloses an absorbent article in which a core pressing portion is provided in an absorbent core. The core extrusion part of patent document 1 is a dot shape or a line shape, and is arrange|positioned at intervals in the longitudinal direction and the width direction. The core extruded portion is arranged over substantially the entire area of ​​the absorbent core (Patent Document 1 figure 1 and Figure 6). [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2014-68745 [0006] According to the absorbent article of Patent Document 1, the rigidity of the absorbent core can be increased over substantially the entire area of ​​the absorbent core. However, since the rigidity of almost the entire area of ​​the absorbent core is high, ...
