Definitions
- the present invention relates to an absorbent article such as a sanitary napkin.
- Patent Document 1 discloses an absorbent article having a surface material that covers the surface of the absorbent body and the side surface of the absorbent body, and a side sheet (a leak-proof material) that extends outward in the width direction from the surface material and the absorbent body.
- the surface material is constituted by a nonwoven fabric having liquid permeability
- the side sheet is constituted by a nonwoven fabric having a hydrophobic surface.
- the surface and side surfaces of the absorber are directly covered with a surface material, and menstrual blood is absorbed not only from the skin contact surface side but also from the side surface side.
- seat is extended in the width direction outer side rather than the absorber, The menstrual blood on the said side sheet
- the side sheet is composed of a hydrophobic non-woven fabric
- menstrual blood tends to remain on the surface as compared with a surface sheet made of a hydrophilic non-woven fabric.
- menstrual blood may leak and the clothes may become dirty.
- a wearer visually recognizes the state in which a lot of menstrual blood is adhered on the side sheet, there is a concern that anxiety about leakage may increase.
- the absorbent article is repeatedly compressed inward in the width direction.
- the width of the absorbent article is further shortened, and the amount of menstrual blood that adheres to the side sheet increases.
- clothes may become dirty due to the leakage of menstrual blood, or the wearer may feel anxious about the leakage.
- the present invention has been made in view of the above-described problems, and suppresses menstrual blood leakage in the crotch region of the absorbent article even when used for a long time, and anxiety about leakage during use. It aims at providing the absorptive article which can control.
- an absorbent article (absorbent article 1) includes a front-rear direction (front-rear direction L), a width direction orthogonal to the front-rear direction (width direction W), a thickness direction, A liquid-permeable top sheet (top sheet 10), a liquid-impermeable back sheet (back sheet 20), and an absorber (absorber) disposed between the top sheet and the back sheet 30) and a pair of side sheets (side sheets 41) covering the width direction outer side end portions of the absorber, and the width direction inner end portions (width direction inner end portions 41A) of the pair of side sheets are , Arranged in the thickness direction between the absorbent body and the top sheet, the pair of side sheets extends outward in the width direction from the top sheet and the absorbent body, the density of the side sheets, Higher than the density of the top sheet It is the gist of.
- FIG. 1 is a top view seen from the skin contact surface side of an absorptive article concerning a 1st embodiment.
- FIG. 2 is a schematic cross-sectional view taken along the line AA shown in FIG.
- FIG. 3 is a diagram schematically showing a wearing state of the absorbent article shown in FIG.
- FIG. 4 is a schematic cross-sectional view of an absorbent article according to a modification.
- FIG. 1 is a plan view of the absorbent article
- FIG. 2 is a cross-sectional view taken along the line AA shown in FIG.
- the absorbent article 1 according to the present embodiment is, for example, a sanitary napkin.
- the absorbent article according to the embodiment includes a front-rear direction extending to a wearer's front side and a rear side of the wearer, a width direction orthogonal to the front-rear direction, an inner direction toward the wearer, and an outer direction facing the inner direction. And a thickness direction having a direction.
- the absorbent article is a daytime sanitary napkin. Therefore, in the absorbent article according to the present embodiment, the length of the front area FA located on the front side of the wearer in the front-rear direction and the rear area BA located on the rear side of the wearer are substantially the same.
- region between a pair of wing parts mentioned later is center area
- a front side of the central area CA is a front side area FA
- a rear side of the central area CA is a rear side area BA.
- a daytime sanitary napkin is described as an example, but the absorbent article according to the present invention can also be applied to a night sanitary napkin.
