Abstract
A disposable panty shield has a thin, highly absorbent pad having a body-contacting surface, an absorbent layer, a liquid barrier, an adhesive layer, and a release layer to protect the positioning adhesive prior to use wherein the panty shield has been densified by fusing all pad layers together in a manner such that the interstitial space between the individual fibers in the densified areas is not sufficient to readily allow fluid to flow through, and the liquid barrier has a contoured surface. The adhesive layer is attached to the liquid barrier such that the adhesive follows the contour of the liquid barrier.
Claims7
A process for applying a layer of adhesive onto a substrate having at least one surface containing at least one recess, wherein each of said at least one recess comprises a bottom surface that is not in the same plane as the at least one surface of the substrate, the process comprising the steps of:
- a. applying a layer of adhesive to a transfer layer;
- b. bringing the adhesive layer into contact with the at least one recess containing surface of the substrate;
- and
- c. applying sufficient pressure across the transfer layer and the bottom surface of the at least one recess to force the adhesive layer into contact with the bottom surface of the at least one recess, wherein the pressure is applied in a pattern corresponding to the at least one recess in the at least one surface of the substrate, whereby the adhesive layer follows the contours of the at least one recess-containing surface.
