Abstract

An absorbent article includes an absorbent body provided between a liquid permeable topsheet and a backsheet; and embosses formed at both sides of the liquid permeable topsheet, wherein each of the embosses includes a body fluid expelling part emboss formed at an area corresponding to a body fluid expelling part along a longitudinal direction of the absorbent article, and is constituted of a shaped line protruding outward in a width direction of the absorbent article, longitudinal direction embosses formed at front and rear of the body fluid expelling part emboss along the longitudinal direction of the absorbent article, respectively, and inclined embosses extending from outer end portions of the longitudinal direction embosses, respectively, and being inclined toward a center side in the width direction of the absorbent article, and wherein end portions of the right and left inclined embosses are spaced apart from each other in the width direction.

Claims (34)

1. An absorbent article comprising:

an absorbent body provided between a liquid permeable topsheet and a backsheet; and

a pair of embosses formed at both sides of a surface side of the liquid permeable topsheet,

wherein each of the embosses includes

a body fluid expelling part emboss formed at an area corresponding to a body fluid expelling part along a longitudinal direction of the absorbent article, and is constituted of a shaped line protruding outward in a width direction of the absorbent article,

longitudinal direction embosses formed at the front and the rear of the body fluid expelling part emboss along the longitudinal direction of the absorbent article, respectively, and

inclined embosses extending from outer end portions of the longitudinal direction embosses, respectively, and being inclined, from the outer end portions of the longitudinal direction embosses toward outer sides relative to a center region in the longitudinal direction, respectively, toward a center side in the width direction of the absorbent article, and

wherein end portions of the right and left inclined embosses are spaced apart from each other in the width direction.

2. The absorbent article according to claim 1 ,

wherein two or more pairs of the longitudinal direction embosses are formed at each of front and rear of the pair of body fluid expelling part embosses with spaced apart from each other in the longitudinal direction,

wherein the pairs of longitudinal direction embosses adjacent to the pair of body fluid expelling part embosses are formed to be directly connected to the respective body fluid expelling part embosses, and

wherein the inclined emboss is formed at the outer end portion of each of the longitudinal direction embosses.

3. The absorbent article according to claim 2 , wherein in each of the embosses, each of the longitudinal direction embosses, that is provided relatively outer side with respect to the center region in the longitudinal direction, is provided at a position that does not match an extension line extending from the adjacent longitudinal direction emboss that is at an inner side thereof in the longitudinal direction.

4. The absorbent article according to claim 2 , wherein in each of the embosses, each of the longitudinal direction embosses, that is provided relatively outer side with respect to the center region in the longitudinal direction, is provided inside of an extension line extending from the adjacent longitudinal direction emboss that is at an inner side thereof in the longitudinal direction.

5. The absorbent article according to claim 2 , wherein, among the inclined embosses, each of the inclined embosses formed nearest to the body fluid expelling part emboss is formed such that an angle α, with respect to a width direction line of the absorbent article, is less than or equal to 45°, and each of the inclined embosses formed further outer side is formed such that an angle, with respect to the width direction line of the absorbent article, is less than or equal to 60°.

6. The absorbent article according to claim 2 ,

wherein each of the longitudinal direction embosses is formed to be inclined, toward its outer side relative to the center region in the longitudinal direction, outward in the width direction with respect to a longitudinal direction line of the absorbent article, and

wherein in each of the embosses, an inclined angle of each of the longitudinal direction embosses provided relatively outer side with respect to the center region in the longitudinal direction is set to be larger than an inclined angle of the adjacent longitudinal direction emboss at an inner side thereof with respect to the center region in the longitudinal direction.

7. The absorbent article according to claim 1 ,

wherein two or more pairs of the longitudinal direction embosses are formed at each of front and rear of the pair of body fluid expelling part embosses,

wherein the pairs of longitudinal direction embosses adjacent to the pair of body fluid expelling part embosses are formed to be directly connected to the respective body fluid expelling part embosses,

wherein the inclined emboss is formed at the outer end portion of each of the longitudinal direction embosses, and

wherein each of the longitudinal direction embosses adjacent to the inclined emboss at its outer side relative to the center region in the longitudinal direction is directly connected to the respective inclined emboss.

8. The absorbent article according to claim 1 ,

wherein each of the longitudinal direction embosses adjacent to the body fluid expelling part emboss is formed along a single arc-shaped curve that protrudes inward in the width direction of the absorbent article, and

wherein a position of narrowest portions, at which the distance between the right and left arc-shaped curves becomes the minimum, and a position of maximum protruding portions, at which an outward protruding width in the width direction of the right and left body fluid expelling part embosses, match or are in proximity to each other.

9. The absorbent article according to claim 1 , wherein the distance between end portions of the right and left inclined embosses is one to three times of the length of the respective inclined emboss in the width direction of the absorbent article.

10. The absorbent article according to claim 1 , wherein the groove width of each of the inclined embosses is wider than the groove width of each of the longitudinal direction embosses.

11. The absorbent article according to claim 1 ,

wherein the body fluid expelling part is formed by a single curve.

12. The absorbent article according to claim 1 ,

wherein in each of the embosses, the longitudinal direction embosses are directly connected to the front and the rear of the body fluid expelling part emboss, respectively, and the inclined embosses are directly connected to the outer end portions of the longitudinal direction embosses, respectively.

13. The absorbent article according to claim 1 ,

wherein the body fluid expelling part emboss is formed at the center region in the longitudinal direction of the absorbent article.
