ABSTRACT:
An easily manufactured sanitary napkin, adhesively securable to an undergarment, includes a rectangular fabric sheet, two-thirds of which is covered with a sheet of moisture barrier. A highly absorbent filler pad shorter than the cover layer is inserted on the center third of the fabric sheet and between that sheet and the moisture barrier. The uncovered third of the fabric is then folded over the top of the center third and contacts the moisture barrier overlaying the filler pad. The opposite third with the barrier is folded over the midsection layers to form the napkin. The tab ends of the fold-over fabric and barrier layers extending beyond the ends of the filler pad are then heat-pressure sealed together and an adhesive strip having a peel-off backing strip is applied to each of the tab ends that are a continuous and integral part of the napkin.
