Absorbent article
An absorbent article includes: a main body ( 8 ) including a liquid permeable top sheet ( 3 ), a liquid impermeable back sheet ( 2 ), and an absorbent body ( 4 ) interposed between the top sheet and the back sheet; and a hip-holding portion (H), wherein the main body has a shape having a predetermined length in a front-back direction and a predetermined width in a direction orthogonal to the front-back direction, and wherein the hip-holding portion includes a side region protruding from a side of a rear portion of the main body, the side region including a first projection ( 41 ) that includes a portion having a largest width from a center line in the front-back direction of the main body, a first recess ( 51 ) that is located adjacent to and forward of the first projection, and a second projection ( 52 ) that is located adjacent to and forward of the first recess, and wherein the back sheet in the side region has a slip preventive portion for securing the absorbent article, the slip preventive portion being disposed so as to straddle, in the front-back direction, a virtual line that is drawn in the width direction from a bottom point of the first recess.
1. An absorbent article comprising
a main body including a liquid permeable top sheet, a liquid impermeable back sheet, and an absorbent body interposed between the top sheet and the back sheet; and a hip-holding portion,
wherein the main body has a shape having a predetermined length in a front-back direction and a predetermined width in a direction orthogonal to the front-back direction, and
wherein the hip-holding portion includes a side region protruding from a side of a rear portion of the main body, the side region including a first projection that includes a portion having a largest width from a center line in the front-back direction of the main body, a first recess that is located adjacent to and forward of the first projection, and a second projection that is located adjacent to and forward of the first recess,
wherein the back sheet in the side region has a slip preventive portion for securing the absorbent article, the slip preventive portion being provided so as to straddle, in the front-back direction, a first virtual line that is drawn in the width direction from a bottommost point of the first recess and a second virtual line that is drawn in the width direction from a topmost point of the first projection.
2. The absorbent article according to claim 1 , wherein the slip preventive portion extends, in the front-back direction, an equal length on both sides of the virtual line that is drawn in the width direction from the bottom point of the first recess.
3. The absorbent article according to claim 1 , wherein each of the side regions has a single slip preventive portion of the slip preventive portions.
4. An absorbent article comprising:
a main body including a liquid permeable top sheet, a liquid impermeable back sheet, and an absorbent body interposed between the top sheet and the back sheet; and a hip-holding portion,
wherein the main body has a shape having a predetermined length in a front-back direction and a predetermined width in a direction orthogonal to the front-back direction,
wherein the hip-holding portion includes a side region protruding from a side of a rear portion of the main body, the side region including a first projection that includes a portion having a largest width from a center line in the front-back direction of the main body, a first recess that is located adjacent to and forward of the first projection, and a second projection that is located adjacent to and forward of the first recess,
wherein the back sheet in the side region has a slip preventive portion for securing the absorbent article, the slip preventive portion being provided so as to straddle, in the front-back direction, a virtual line that is drawn in the width direction from a bottom point of the first recess, and
wherein the slip preventive portion has an elongated shape, and a longitudinal axis of the slip preventive portion is aligned approximately in parallel with a virtual line that passes through the bottom point of the first recess and a top point of the first projection, and not along the front-back direction.
