ABSORBENT ARTICLE HAVING IMPROVED ADHESIVE SYSTEM TO PROVIDE FLEXIBILITY AND BREATHABILITY
First Claim
1. An absorbent article having a body-facing side and a garment-facing side, said absorbent article comprising:
- (a) a liquid pervious topsheet defining said body-facing side of said absorbent article;
(b) a liquid impervious backsheet joined to said topsheet and defining said garment-facing side of said absorbent article;
(c) an absorbent layer being positioned between said topsheet and said backsheet; and
(d) an adhesive system located on said backsheet, said adhesive system comprising a plurality of three-dimensional protrusions which are deformable into a substantially two-dimensional configuration and an interconnected network of adhesive surrounding said protrusions which is protected from inadvertent contact with external surfaces until said three-dimensional protrusions are deformed into said substantially two-dimensional configuration, said adhesive system having a number density of protrusions greater than about 75.

Abstract
An absorbent article, such as a diaper, a sanitary napkin, a panty liner, an adult incontinence device, a bandage, or the like is provided which has: (a) a liquid pervious topsheet defining a body-facing side of the absorbent article; (b) a liquid impervious backsheet joined to the topsheet and defining a garment-facing side of the absorbent article; (c) an absorbent layer being positioned between the topsheet and the backsheet; and (d) an adhesive system located on the backsheet. The adhesive system comprises a plurality of three-dimensional protrusions which are deformable into a substantially two-dimensional configuration and an interconnected network of adhesive surrounding the protrusions which is protected from inadvertent contact with external surfaces until the three-dimensional protrusions are deformed into a substantially two-dimensional configuration. The absorbent article preferably includes a plurality of flaps which may themselves preferably include an adhesive system, and the backsheet of the absorbent article is preferably breathable.
