Method for making an absorbent product having integrally protected adhesive
First Claim
1. A method of applying and protecting positioning adhesive on an absorbent article having a fluid impervious barrier having a first surface forming a garment facing surface of such article and a second surface opposite said first surface, comprising the steps of:
- a) deforming portions of said barrier so as to form a plurality of depressions in a pattern on said first surface of said barrier so as to form a corresponding raised area in said second surface of said barrier opposite each of said depressions; and
b) depositing an adhesive within said depressions on said first surface of said barrier.

Abstract
A method of making an absorbent product in which pressure sensitive adhesive is used to attach the product to a user'"'"'s undergarment. The product does not require release paper to protect the adhesive from unintended contact prior to use. The product is made by forming depressions in a fluid impervious barrier so as to create raised areas in the barrier that protect the adhesive. The depressions may be formed in the garment facing surface of the barrier and the adhesive applied within the depressions so that the raised areas adjacent the depressions protect the adhesive. Alternatively, the depressions may be formed in the surface of the barrier opposite the garment facing surface so as to create raised areas in the garment facing surface and the adhesive applied adjacent the raised areas.

8. A method of applying and protecting positioning adhesive on an absorbent article having a fluid impervious barrier having a first surface forming a garment facing surface of such article and a second surface opposite said first surface, comprising the steps of:
-
a) deforming portions of said barrier so as to form a plurality of depressions in a pattern on said second surface of said barrier, whereby said first surface has raised areas opposite each and corresponding to said depressions on said second surface and recessed areas in remaining portions of said first surface; and b) depositing an adhesive on said recessed areas of said first surface of said barrier. - View Dependent Claims (9)

12. A method of making an absorbent article having a fluid impervious barrier that forms a garment facing surface of said article, comprising the steps of:
-
a) depositing a pressure sensitive adhesive in a first pattern on said garment facing surface of said barrier; and b) depositing a non-pressure sensitive foaming adhesive in a second pattern on said garment facing surface of said barrier, said non-pressure sensitive foaming adhesive foaming to a thickness greater than said pressure sensitive adhesive so as to form areas raised above said pressure sensitive adhesive and said second pattern provides sufficient void areas to expose said pressure sensitive adhesive. - View Dependent Claims (13)

14. A method of applying and protecting positioning adhesive on an absorbent article having a fluid impervious barrier having a first surface forming a garment facing surface of such article and a second surface opposite said first surface, comprising the steps of:
-
transferring said adhesive from a reservoir onto a release surface in a pattern, said adhesive capable of bonding to said barrier with greater tenacity than to said release surface; transferring said adhesive from said release surface onto said first surface of said barrier in said pattern; and deforming portions of said barrier so as to form a plurality of depressions in said pattern on said first surface of said barrier so as to form a corresponding raised area in said second surface of said barrier opposite each of said depressions; wherein said adhesive is located in said depressions. - View Dependent Claims (15, 16, 17)
