ABSTRACT:
Tabless adhesive fasteners are provided for diapers. In one aspect of the invention, one face of each adhesive fastener is permanently bonded to the diaper assembly proper at an associated permanent-bond area of the diaper assembly proper at one of the two lateral sides of the diaper assembly proper and adjacent the periphery of the diaper assembly proper. The other face of each adhesive fastener is releasably carried by liner or tape protective means carried on an area of the diaper assembly proper which is offset from such associated permanent-bond area. In another aspect of the invention, the adhesive fasteners include an adhesive layer which penetrates the water-permeable inner layer of the diaper assembly proper and adhesively interacts with the water-impermeable outer layer of the diaper assembly proper, whereby such adhesive layer and inner and outer diaper layers cooperate to provide a reinforced fastener base. Each adhesive fastener may comprise two adhesive layers with a carrier layer between them.
