Abstract
The invention is an improved attachment strap for a large diaper or adult incontinent pad. It consists of an accordion pleated length of material, preferably a nonwoven fabric, with one end permanently attached to the diaper body. The final pleat at the opposite end is terminated by a length of peelable pressure sensitive tape which overhangs each edge of the pleat. The medially oriented overhang is relatively narrow while the laterally oriented overhang, which ultimately serves as an attachment tab, is relatively wider. When in stored position, the two overhanging portions hold the folded tape compactly against the back face of the diaper where they do not interfere with manufacturing or packaging operations. The peelable attachment tape has an adhesive coating that is relatively high in shear strength but modest in peel strength. These characteristics are chosen so that the tape can be peeled off without tearing the diaper backing sheet. The diaper can be removed for inspection and then be reused, if unsoiled, without damage to the backing sheet.
