Abstract
Disclosed is a hygienic absorbent article including: a back layer; an absorbent layer; and a three-dimensional portion to rise in T-shaped state over the absorbent layer due to longitudinal elastic contractive force of elastic members provided in the three-dimensional portion. The three-dimensional portion has: connecting portions fixed onto the absorbent layer; and a skin-contacting portion connected to the absorbent layer through the connecting portions and having a pair of free ends.
Claims22
A hygienic absorbent article comprising:
- a main body including a back layer and an absorbent layer having two side edges extending in a longitudinal direction of the article and laid on the back layer;
- a three-dimensional portion extending in the longitudinal direction of the article and provided over the absorbent layer, the three-dimensional portion being fixed at two fixed ends thereof onto the main body, the fixed ends being located between the two side edges of the absorbent layer, the three-dimensional portion including two connecting portions to rise from the fixed ends and a skin-contacting portion extending between upper ends of the connecting portions to have a pair of free ends, each free end being located closer to corresponding one of the side edges of the absorbent layer than the fixed end, at least an upper face of the skin-contacting portion being made of a liquid-permeable material;
- and
- elastic members provided in the three-dimensional portion to extend in the longitudinal direction of the article for applying a longitudinal elastic contractive force to the three-dimensional portion so that the three-dimensional portion is allowed to rise to have the free ends of the skin-contacting portion spaced above the main body while being anchored at the fixed ends to the main body.

A hygienic absorbent article comprising:
- a main body including a back layer and an absorbent layer having two side edges extending in a longitudinal direction of the article and laid on the back layer;
- first and second three-dimensional portions extending in the longitudinal direction of the article and symmetrically provided over the absorbent layer with respect to a longitudinally extending centerline of the absorbent layer, the first and second three-dimensional portions being fixed at fixed ends thereof onto the main body, the fixed ends being located between the two side edges of the absorbent layer, each three-dimensional portion including a connecting portion to rise from the fixed end and a skin-contacting portion bent from the connecting portion outwardly to have a free end located closer to corresponding one of the side edges of the absorbent layer than the fixed end, at least an upper face of the skin-contacting portion being made of a liquid-permeable material;
- and
- elastic members provided in the first and second three-dimensional portions to extend in the longitudinal direction of the article for applying a longitudinal elastic contractive force to the first and second three-dimensional portion so that the first and second three-dimensional portions are allowed to rise to have the free ends of the skin-contacting portions spaced above the main body while being anchored at the fixed ends to the main body.
