Abstract
A plurality of openings (11) is formed in a region corresponding to at least a body fluid discharge region (H) of a liquid permeable top sheet (3). A polymer sheet (6) disposed adjacent to a surface of an absorbent body (4) side of the liquid permeable top sheet (3) is included, and the polymer sheet includes highly absorbent resin disposed along a longitudinal direction on both sides of the region corresponding to the body fluid discharge region (H). Upon the highly absorbent resin becoming swollen by absorption, a space (10) for holding a body fluid is formed between regions in which the highly absorbent resin is disposed (12) and also between the liquid permeable top sheet (3) and the polymer sheet (6).
Claims6
An absorbent article comprising:
- a liquid permeable top sheet including a plurality of openings in a region corresponding to at least a body fluid discharge region;
- a back sheet;
- an absorbent body provided between the liquid permeable top sheet and the back sheet;
- and
- a polymer sheet disposed adjacent to a surface of an absorbent body side of the liquid permeable top sheet, the polymer sheet including two regions of highly absorbent resin disposed along a longitudinal direction at only respective ends on both sides of the region corresponding to the body fluid discharge region,
- wherein, before the highly absorbent resin becomes swollen, a surface of the polymer sheet is formed flat,
- wherein, upon the highly absorbent resin becoming swollen by absorption and raised toward a skin side, the liquid permeable top sheet located between disposed regions of the highly absorbent resin is raised toward the skin side, and thereby, a space for holding a body fluid is formed between regions in which the highly absorbent resin is disposed and also between the liquid permeable top sheet and the polymer sheet.
