Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 117 words
An auxiliary absorbent article for use atom a primary absorbent article having absorbent capacity and wicking ability, said auxiliary absorbent article enhancing the absorptive capacity of the primary absorbent article, said auxiliary absorbent article comprising a superabsorbent layer, an upper facing layer, and an undersurface, said superabsorbent layer comprising a superabsorbent material dispersed in a matrix such that fluid passes through said auxiliary absorbent article and may be absorbed by the primary absorbent article, wicked along the undersuface of the auxiliary absorbent article, and absorbed through the undersurface of the super-absorbent layer in remote regions from the initial wetting of the auxiliary absorbent article whereby the full absorbent capacity of the primary absorbent article may be utilized.
Claim 2
Dependent Claim 117 words
An auxiliary absorbent article for use atom a primary absorbent article having absorbent capacity and wicking ability, said auxiliary absorbent article enhancing the absorptive capacity of the primary absorbent article, said auxiliary absorbent article comprising a superabsorbent layer, an upper facing layer, and an undersurface, said superabsorbent layer comprising a superabsorbent material dispersed in a matrix such that fluid passes through said auxiliary absorbent article and may be absorbed by the primary absorbent article, wicked along the undersuface of the auxiliary absorbent article, and absorbed through the undersurface of the super-absorbent layer in remote regions from the initial wetting of the auxiliary absorbent article whereby the full absorbent capacity of the primary absorbent article may be utilized.
Claim 3
Dependent Claim 13 words
An auxiliary absorbent article as in claim 1 wherein said article is T-shaped.
Claim 4
Dependent Claim 23 words
An auxiliary absorbent article as in claim 1 with intermittent adhesive disposed on the undersurface thereof for fastening to the primary absorbent article.
Claim 5
Dependent Claim 20 words
