Abstract
Abstract An absorbent article, illustrated as a disposable diaper, includes a primary absorbent member and an auxiliary absorbent member. The primary absorbent member has an upper liquid-receiving surface area. The auxiliary absorbent member includes a liquid-permeable lower surface region, and a pair of substantially liquid-impermeable upstanding leg gathers in at least a target area of the absorbent article. An attachment arrangement joins the primary and auxiliary absorbent members to position the liquid-permeable lower surface region of the auxiliary absorbent member in liquid-transferring relationship with the upper liquid-receiving surface area of the primary absorbent member.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
170 words
An absorbent article, comprising: a primary absorbent member having an upper, liquid receiving surface area; a pair of side marginal sheets extending in spaced relationship to each other along respective opposite side edges of said primary absorbent member; an auxiliary absorbent member positioned on top of said primary absorbent member and defining a liquid-permeable region at a lower surface thereof; a pair of upstanding leg gathers extending upwardly from respective side edges of said lower surface of said auxiliary absorbent member, in at least a target area of said absorbent article to abate passage of liquid transversely of said auxiliary absorbent member, said pair of leg gathers extending from a region between said primary absorbent member and said auxiliary absorbent member; and attachment means for respectively joining said upstanding leg gathers to said marginal sheets generally at an upper surface of said primary absorbent member to position said liquid-permeable lower surface region of the auxiliary absorbent member in liquid-transferring relationship with said upper liquid-receiving surface of the primary absorbent member.
Claim 2
Dependent Claim
