Abstract

The present invention discloses a disposable absorbent pant or diaper having a crotch portion and front and back portions adjacent thereto which are joined to form a waist portion surrounding the waist of the user. The waist portion is circumferentially elastic around the waist of the user. At least one cover layer extends from at least the front portion to the back portion and an absorbent body is disposed adjacent to the at least one cover layer. The absorbent body is held tightly against the body of the user by the elastic waist portion. At least portions of the surface of the waist portion facing the skin of the user are provided with a friction agent to form a friction increasing surface against the skin of the user.

Claims

1. Disposable absorbent pant, comprising a crotch portion, front and back portions adjacent thereto which are joined to form a waist portion of the disposable absorbent pant for surrounding the waist of a user, said waist portion being circumferentially elastic, at least one cover layer extending from at least said front portion to said back portion, an absorbent body disposed adjacent to said at least one cover layer, said absorbent body being held tightly against the body of the user by the elastic waist portion, wherein at least portions of the surface of the waist portion facing the skin of the user are provided with skin engagement means for increasing friction against the skin, relative to the surface of said waist portion, and thereby creating frictional resistance with the skin.

2. Disposable absorbent pant according to claim 1, wherein the friction agent is flexible and compliant with the elastic waist portion.

3. Disposable absorbent pant according to claim 1, wherein the skin engagement means for increasing friction includes a hot-melt material.

4. Disposable absorbent pant according to claim 3, wherein the hot-melt material is based on a thermoplastic rubber.

5. Disposable absorbent pant according to claim 1, wherein the friction agent consists of a water-based material.

6. Disposable absorbent pant according to claim 1, wherein the friction agent consists of a material of foam-type.

7. Disposable absorbent pant according to claim 1, wherein the friction agent is arranged in portions extending in a row around the entire inside of the waist portion.

8. Disposable absorbent pant according to claim 1, wherein the waist portion includes a right hip portion and a left hip portion, the friction agent being arranged in portions which only extend along the right and left hip portions of the waist portion.

9. Disposable absorbent pant according to claim 1, wherein the friction agent extends in a continuous strip along the waist portion.

10. Disposable absorbent pant according to claim 1, wherein the friction agent is arranged in the form of points on the inside of the waist portion.

12. Disposable absorbent pant according to claim 1, wherein the absorbent body is connected to said at least one cover layer.

13. Disposable absorbent pant according to claim 1, wherein said at least one cover layer includes two cover layers and the absorbent body is enclosed between the two cover layers.

11. A disposable absorbent diaper comprising:

a crotch portion;

front and back portions adjacent to the crotch portion which are joined together to form a waist portion of the disposable absorbent diaper for surrounding the waist of a user, said waist portion being circumferentially elastic;

at least one cover layer extending from at least said front portion to said back portion; and

an absorbent body disposed adjacent to said at least one cover layer, said absorbent body being held tightly against the body of the user by the elastic waist portion;

wherein at least portions of the surface of the waist portion facing the skin of the user are provided with skin engagement means for increasing friction against the skin of the user, relative to the surface of said waist portion, and thereby creating frictional resistance with the skin.

14. Disposable absorbent diaper according to claim 11, wherein the absorbent body is connected to said at least one cover layer.

15. Disposable absorbent diaper according to claim 11, wherein said at least one cover layer includes two cover layers and the absorbent body is enclosed between the two cover layers.

16. Disposable absorbent pant, comprising a crotch portion, front and back portions adjacent thereto which are joined to form a waist portion for surrounding the waist of a user of the disposable absorbent pant, said waist portion being circumferentially elastic, at least one cover layer extending from at least said front portion to said back portion, an absorbent body disposed adjacent to said at least one cover layer, said absorbent body being held tightly against the body of the user by the elastic waist portion, wherein at least portions of the surface of the waist portion facing the skin of the user are provided with skin engagement means for increasing friction against the skin, relative to the surface of said waist portion, said skin engagement means providing smooth contact surfaces for contacting the skin of the user and creating a frictional resistance therewith.
