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.

Claims

1. A disposable diaper or incontinent pad having a body contacting facing sheet, a moisture impervious backing sheet generally coextensive with the facing sheet, an absorbent panel disposed between the backing and facing sheets, and a pair of fastener means located on opposite edges near adjacent corners of the diaper or pad, each of which comprises:

a flexible attachment strap accordion pleated to form a folded unit comprising a plurality of generally coextensive articulated segments,

the initial segment of one end of said attachment strap being permanently anchored to the backing sheet,

the final segment at the opposite end of the attachment strap being terminated by a pressure sensitive adhesive backed tape having a repositionable-type adhesive,

said repositionable adhesive backed tape overhanging each edge of said final segment and the associated coextensive pleated strap unit whereby the overhanging portions serve to hold said unit compactly against the diaper backing sheet until the time of use, whereupon the adhesive backed tape can be peeled from said backing sheet while remaining attached to the strap so that the strap can be extended and one of the overhanging portions of said adhesive backed tape serve as an attachment tab to secure the strap to the front of the diaper or incontinent pad for use by a wearer.

2. The diaper or incontinent pad of claim 1 in which the initial segment of the attachment strap is adhesively bonded to the backing sheet.

3. The diaper or incontinent pad of claim 2 in which the flexible attachment strap is a nonwoven fabric.

4. The diaper or incontinent pad of claim 2 in which the flexible attahcment strap is a polyolefin film.

5. The diaper or incontinent pad of claim 1 in which the initial segment of the attachment strap is bonded to the backing sheet by a strip of pressure sensitive adhesive tape having a permanent type adhesive.

6. The diaper of incontinent pad of claim 5 in which the flexible attachment strap is a nonwoven fabric.

7. The diaper of incontinent pad of claim 5 in which the flexible attachment strap is a polyolefin film.

8. The diaper or incontinent pad of claim 1 in which the flexible attachment strap is a nonwoven fabric.

9. The diaper or incontinent pad of claim 1 in which the flexible attachment strap is a polyolefin film.
