ABSTRACT:
A disposable absorbent product such as a panty liner (or pantiliner) or sanitary napkin or product for incontinents having a resilient, scalloped perimetrical edge, and a method of making the product. In a preferred laminated embodiment, a resilient absorbent core lamina is disposed between and coextensive--at least in their edge areas--with a liquid permeable topsheet and a liquid barrier backsheet. The elements are bonded together by a multiplicity of perimetrically spaced, compacted bonded areas which impart a scalloped character to the edge of the product, and wherein each scallop is filled with an edge portion of the resilient absorbent core lamina. Each bonded area is preferably elongate, and orthogonally disposed with respect to the edge of the product; and, preferably, each bonded area comprises a plurality of concatenated discrete bonds for improved flexibility.
