Claim:
A waste disposal pad and device for an animal comprising: a feed section including a feed roll and a take up section including a take up roll; an absorbent pad having a first and second surface adapted for use between said feed section and said take-up section wherein said pad further includes a portion having a surface sealing feature, and wherein said first surface of said absorbent pad is adapted to contact said second pad surface when positioned on said take-up section; said surface sealing feature providing a seal when said first pad surface contacts said second pad surface on said take up roll, wherein said absorbent pad itself has a cross-sectional thickness, and said surface sealing feature of said pad has a cross-sectional thickness and where the cross-sectional thickness of said sealing feature and the pad is greater than said pad cross-sectional thickness; wherein said pad comprises a top sheet layer, an inner region absorbent layer and a moisture barrier layer, wherein said top sheet layer includes a woven hydrophobic polyolefin polymer and said inner region includes a hydrophilic polymer wherein animal waste is transported from said polyolefin polymer to said hydrophilic polymer within said pad; wherein said absorbent layer contains three dimensional features providing recesses in said first surface providing a volume to collect said waste; and wherein said absorbent pad has a length and a width, the width defined by two edges, and said surface sealing feature comprises an adhesive pattern along said length and at spaced intervals across the entirety of said width to define a region having a length and a width that is sealed along said length and width when the pad is rolled on the take-up roll, said pattern selected from the group consisting of zig-zag, sawtooth, sinusoidal or mixtures thereof; wherein said take up roll has ends and a center portion, said ends having a first diameter and said center portion having a second diameter, where said second diameter is less than said first diameter.
