Embodiment 1

[0185] manufacture Figure 9 Absorbent core in the form shown. The absorbent core 41 is formed as a mixed fiber accumulation body of pulp fibers and a water-absorbent polymer. The absorptive core 41 has a mid-height portion 42 in the middle region 41M, the mid-height portion 42 has a mid-height central portion 421 over the entire width of the absorptive core 41, and front side convex portions 422 and rear side convex portions 422 at the front and rear ends of the mid-height central portion 421, respectively. side convex part 423 . The middle height portion 42 has a thickness of 3.5 mm, and the thicknesses of the first region 41F and the second region 41R are 2 and 3 mm. The gram weight of middle and high part 42 is 350g / m 2 , the grammage of the first region 41F and the grammage of the second region 41R are 250g / m 2 . Thickness and grammage were measured by the methods mentioned above. Moreover, the full length L2 of the vertical direction X of the middle height part 42 ...

Abstract

The invention provides an absorbent article. This absorbent article (1) is provided with an absorbent core (41). The absorbent core (41) has a convex portion (42) in an excretion facing section (B). The convex portion (42) is thicker than a first region (41F) and a second region (41R) of the absorbent core (41). The convex portion (42) has a maximum width portion in which the absorbent core (41) has a maximum length in a transverse direction (Y) perpendicular to a longitudinal direction (X) in a plane view. The length in the transverse direction (Y) of the maximum width portion is the same asthe maximum length in the transverse direction (Y) of an intermediate region (41M) of the absorbent core (41).

Description

technical field [0001] The present invention relates to absorbent articles such as sanitary napkins and incontinence pads. Background technique [0002] Conventionally, in absorbent articles such as sanitary napkins, when a large amount of liquid is excreted, liquid leakage may occur during daily activities of life. Therefore, the present applicant proposes a method for preventing liquid leakage by providing a heavy mid-height portion in an excretion-facing region disposed opposite to the wearer's liquid excretion portion in the absorbent core of an absorbent article, and , A horizontal groove with a low grammage is provided in the middle and high part to spread the liquid without stagnating at the discharge point, thereby preventing liquid leakage (for example, Patent Document 1 to Patent Document 2). [0003] For example, Patent Document 1 proposes a technique in which a surface structure having a mid-height portion raised toward the skin is provided on a surface facing t...
