Abstract
Abstract An absorbent product is disclosed which includes a fluid impervious barrier sheet at one side thereof adhered to an absorbent pad that is surrounded, at least in part, by a fluid pervious cover to be positioned against the body of the wearer. The barrier sheet includes a central strip of pressure sensitive adhesive for adhering the absorbent product to a garment, and a protective cover strip is releasably adhered to the pressure sensitive adhesive. The barrier sheet is secured in place by a plurality of spaced parallel lines of adhesive on the surface thereof opposite to the strip of pressure sensitive adhesive. This surface also includes a band of adhesive in alignment with the strip of pressure sensitive adhesive to reinforce the midportion of the product and prevent different sections of the strip of pressure sensitive adhesive from inadvertently adhering to one another once the protective cover strip has been removed. The band of adhesive includes a rectangular area generally coextensive with the length of the absorbent pad, and a plurality of lines of adhesive extend outwardly from opposite ends of the generally rectangular area into the tab portions of the product. Such lines of adhesive are spaced from one another by a distance generally the same as the distance between the lines of adhesive outwardly of the adhesive band.
