Absorbent articles

Abstract

To prevent deformation of an absorbent core.SOLUTION: An absorbent article having a length in a longitudinal direction and a length in a width direction perpendicular to the longitudinal direction includes: an absorber which absorbs excreted liquid discharged from a wearer and has an absorbent core; a top sheet which is arranged on a skin surface side of the absorber and has a water-permeable area; a back sheet which is arranged on a non-skin surface side of the absorber and is wider than the absorber and water-impermeable; and an exterior body arranged on a non-skin surface side of the back sheet. On at least an area adjacent to an end part of the absorbent core or an area overlapped with the end part of the absorbent core of the exterior body, an expanding and contracting member which expands and contracts in the width direction of the absorber is provided.SELECTED DRAWING: Figure 1

Claims

1. An absorbent article having a length along the longitudinal direction and a length along the width direction perpendicular to the longitudinal direction, An absorbent body having an absorbent core that absorbs the excretory fluids produced by the wearer, The absorbent material has a top sheet with a water-permeable region, which is positioned on the skin-facing side. A back sheet, which is wider than the absorbent and impermeable to water, is positioned on the non-skin side of the absorbent; An interior body having, An exterior body positioned on the non-skin side of the interior body, Equipped with, A first expandable / contractable member that contracts in the width direction of the absorber is provided in at least one of the regions of the outer casing adjacent to the end of the absorber core or overlapping with the end of the absorber core. The back sheet is folded back at the end of the absorbent body in the width direction, covering the absorbent body from the non-skin side through the side portion to the skin side. The top sheet is folded back at the end of the absorbent body in the width direction, covering the side portion of the absorbent body from the skin side, from the outside of the back sheet. The non-skin side of the back sheet and the outer casing are directly bonded together. The absorbent further comprises side sheets that cover the sides in the width direction, The side sheet has a three-dimensional gather on the skin-facing side of the absorbent material, in which a third stretchable member that stretches in the longitudinal direction is arranged. The side sheet is bonded to the skin-facing end in the width direction of the top sheet, and the center of the bonded portion in the width direction becomes the upright line of the three-dimensional gather. Absorbent material.

2. The absorption core has a shape that is constricted in the width direction at the center of the longitudinal direction, The absorbent article according to claim 1.

3. The area inside the imaginary extension line that extends the width of the absorption core in the longitudinal direction at the central part in the longitudinal direction of the absorption core has a higher base weight. At both ends of the absorption core in the longitudinal direction, the central portion in the width direction is a high-weight portion, and the remaining portions are low-weight portions. The absorbent article according to claim 2.

4. The aforementioned high-density portion extends with the same width to both ends of the absorption core in the longitudinal direction. The absorbent article according to claim 3.

5. The aforementioned high-weight portion extends with the same weight throughout the entire extended portion. The absorbent article according to claim 3.

6. The side sheet extends beyond the longitudinal end of the absorption core. The absorbent article according to claim 1 or 2.

7. When the absorbent article is viewed from above, the longitudinal end of the three-dimensional gather is provided at the widthwise end of the overlapping portion of the top sheet that overlaps with the absorbent core. The absorbent article according to claim 1 or 2.

8. The overlapping portion and the longitudinal end of the side sheet are bonded together. The back sheet extends in the longitudinal direction toward the end of the absorption core, The adhesive portion of the side sheet extends beyond the end of the absorbing core to the longitudinal end of the back sheet. The absorbent article according to claim 7.
