Abstract

An absorbent article having improved adhesive attachment means to secure the absorbent article in the crotch region of a garment. The adhesive attachments means of this invention consists of an adhesive pattern having the shape of a block "I". The block I being defined by a base portion, a stem portion, and a head portion.

Claims

1. An absorbent article designed to be worn in the crotch region of a garment, the absorbent article having a central region, a first end region and a second end region, the absorbent article comprising:

an absorbent core;

a backsheet associated with said absorbent core; and

adhesive attachment means disposed on said backsheet for securing the absorbent article to a garment, said adhesive attachment means consisting of an adhesive pattern having the shape of a block I having

a base adhesive portion located in said first end region of the absorbent article,

a stem adhesive portion centrally located in said central region of the absorbent article, and

a head adhesive portion located in said second end region of the absorbent article.

2. The absorbent article of claim 1 wherein said head adhesive portion and said base adhesive portion of said adhesive attachment means each comprises a strip of adhesive that extends transversely across the absorbent article.

3. The absorbent article of claim 1 wherein said head adhesive portion and said base adhesive portion of said adhesive attachment means each comprises at least two strips of adhesive that extend transversely across the absorbent article.

5. The absorbent article of claim 1 wherein said stem adhesive portion of said adhesive attachment means comprises a line of adhesive.

6. The absorbent article of claim 5 wherein said head adhesive portion and said base adhesive portion of said adhesive attachment means each comprises a strip of adhesive that extends transversely across the absorbent article.

7. The absorbent article of claim 5 wherein said head adhesive portion and said base adhesive portion of said adhesive attachment means each comprises at least two strips of adhesive that extend transversely across the absorbent article.

9. The absorbent article of claim 1 wherein said stem adhesive portion of said adhesive attachment means comprises discrete spaced strips of adhesive.

10. The absorbent article of claim 9 wherein said head adhesive portion and said base adhesive portion of said adhesive attachment means each comprises a strip of adhesive that extends transversely across the absorbent article.

11. The absorbent article of claim 9 wherein said head adhesive portion and said base adhesive portion of said adhesive attachment means each comprises at least two strips of adhesive that extend tranversely across the absorbent article.

12. The absorbent article of claim 9 wherein said head adhesive portion and said base adhesive portion of said adhesive attachment means each comprises at least two strips of adhesive that extend longitudinally along the absorbent article.

13. The absorbent article of claim 1 wherein said base adhesive portion and said head adhesive portion each comprises a generally rectangular zone extending transversely across the respective end region in which each is located wherein the area of said zone comprises at least about fifty percent of the effective adhesive area of each respective end region.

14. The absorbent article of claim 13 wherein said base adhesive portion and said head adhesive portion are each located so as to be equidistantly inwardly spaced from the longitudinal edges of the absorbent article.

15. The absorbent article of claim 14 wherein said base adhesive portion and said head adhesive portion are each equidistantly inwardly spaced about 6 mm from the longitudinal edges of the absorbent article.

16. The absorbent article of claim 1 wherein said stem adhesive portion comprises a narrow rectangular zone extending longitudinally in the central region of the absorbent article wherein the area of said zone comprises less than about 50% of the effective adhesive area of said central region.

17. The absorbent article of claim 16 wherein the area of said zone comprises less than about 30% of the total effective adhesive area of said central region.

18. The absorbent article of claim 16 wherein said stem adhesive portion is located so as to be equidistantly inwardly spaced from the longitudinal edges of the absorbent article.

19. The absorbent article of claim 18 wherein said stem adhesive portion is equidistantly inwardly spaced about 18 mm from the narrowest point of each longitudinal edge of the absorbent article.

20. The absorbent article of claim 1 wherein said base adhesive portion, stem adhesive portion and head adhesive portion each comprise an array of discrete adhesive elements.

4. An absorbent article designed to be worn in the crotch of a garment, the absorbent article having a central region, a first end region and a second end region, the absorbent article comprising:

an absorbent core;

a backsheet associated with said absorbent core; and

adhesive attachment means disposed on said backsheet for securing the absorbent article to a garment, said adhesive attachment means consisting of an adhesive pattern having the shape of a block I having

a base adhesive portion located in said first end region of the absorbent article,

a stem adhesive portion centrally located in said central region of the absorbent article,

a head adhesive portion located in said second end region of the absorbent article, and

said head adhesive portion and said base adhesive portion of said adhesive attachment means each comprising at least two strips of adhesive that extend longitudinally along the absorbent article.

8. An absorbent article designed to be worn in the crotch region of a garment, the absorbent article having a central region, a first end region and a second end region, the absorbent article comprising:

an absorbent core;

a backsheet associated with said absorbent core; and

adhesive attachment means disposed on said backsheet for securing the absorbent article to a garment, said adhesive attachment means consisting of an adhesive pattern having the shape of a block I having

a base adhesive portion located in said first end region of the absorbent article,

a stem adhesive portion centrally located in said central region of the absorbent article, said stem adhesive portion of said adhesive attachment means comprising a line of adhesive,

a head adhesive portion located in said second end region of the absorbent article, and

said head adhesive portion and said base adhesive portion of said adhesive attachment means each comprising at least two strips of adhesive that extend longitudinally along the absorbent article.
