[0005] However, the sanitary napkin described in Patent Document 1 has pouches formed only near the wings, and the pouches are opened by stretching when the wings are folded back toward the outer side of the back sheet.
Therefore, it is not possible to form such a pouch in sanitary napkins without wings, or outside the vicinity of the wings of sanitary napkins.
In addition, the pouch described in Patent Document 1 is likely to be crushed when worn, and the entire pouch is easily broken, or partially turned over.
[0006] If a part of the pouch of the absorbent article described in Patent Document 2 is squeezed, the whole is likely to be crushed or partially turned over.
[0007] In addition, in conventional sanitary napkins with side sheets, the side sheets are often fixed by a linear heat-seal portion along the longitudinal direction of the sanitary napkin. The user's body bends smoothly, and the heat-sealed part may be hard and the feeling of touching the skin may be poor

Embodiment Construction
[0025] Hereinafter, the present invention will be described based on the preferred embodiments of the present invention with reference to the accompanying drawings.
[0026] Such as figure 1 and figure 2 As shown, a sanitary napkin 1 as an embodiment of the absorbent article of the present invention has a liquid-retentive absorbent layer 11 and a liquid-impermeable leak-proof layer 13, and has a substantially elongated absorbent main body 10 and respectively The pair of side sheets 6, 6 are arranged on both sides of the skin-contacting surface side of the absorbent main body 10. As shown in FIG. Formed on the pair of side sheets 6, 6 are joint lines (joint seals) 8 each alternately having a plurality of portions 81 close to the longitudinal centerline CL of the main body and portions 82 distant from the centerline CL, A plurality of pouches 84 are formed in the longitudinal direction between the portions 81 and 81 close to the center line CL.
[0027] Such as figure 2 As...

Abstract
The absorbent product 1 has a pair of side sheets 6 on the both sides of the absorbent body, each of the side sheets 6 being connected to the absorbent product body along the connect lines 8 substantially consecutive toward the longitudinal direction of the absorbent product body, the connect lines 8 having alternately a plurality of sections 81 closer to and sections 82 remote from the axis CL toward the longitudinal direction of the absorbent product body, wherein a pocket 84 is formed between the proximate sections 81 and 81 adjacent to each other toward the longitudinal direction of each of the side sheets 6.
Description
technical field [0001] The present invention relates to absorbent articles such as sanitary napkins, panty liners (fabric sheets), and incontinence pads. Background technique [0002] In absorbent articles such as sanitary napkins, a technique is known in which pouches are formed using side sheets (waterproof nonwoven fabric, etc.) on both sides of the skin-contacting side. [0003] For example, Japanese Unexamined Patent Publication No. 5-51328 proposes a sanitary napkin in which a portion of the inner edge of a liquid barrier sheet forming a wing is superimposed on a surface sheet, and a part of the inner edge is separated from the inner edge. Engaging the barrier sheet with the face sheet in position, a pocket is formed between the barrier sheet and the face sheet. [0004] In addition, JP-A-2001-327535 proposes an absorbent article in which the width of the central part in the longitudinal direction of the absorber is narrower than the width of the front and rear parts,...
