Abstract
A tape fastener for a disposable diaper having opposed surfaces and opening means extending through an absorbent pad of the diaper. The tape fastener has a pressure-sensitive tape strip having a first portion secured to one surface of the diaper with adhesive on the first portion being exposed through the opening means. The fastener also has a release sheet having at least a portion attached to the first portion of the tape strip by the adhesive exposed through the opening means.
Claims26
A disposable diaper, comprising:
- an absorbent pad assembly having an absorbent pad, opposed first and second surfaces, at least one side edge, and opening means extending through the pad assembly including said pad, said opening means being spaced from said side edge;
- and
- a tape fastener comprising.
- a pressure-sensitive tape strip having a first end section secured to the first surface of the pad assembly with adhesive on the first end section being exposed through said opening means of the pad assembly, and a second securement section extending past said side edge of the pad assembly, and
- a sheet having a first surface and a second surface facing the second surface of the pad assembly, with said adhesive exposed through the opening means being fixedly attached to the sheet.

A disposable diaper, comprising:
- an absorbent pad assembly having a back surface, a front surface, at least one side edge, an absorbent pad having an area of a first thickness and a region of reduced thickness adjacent a side edge of the pad, and opening means extending through the pad assembly and said region of the pad, said opening means being spaced from the side edges of the pad assembly and said pad;
- and
- a tape fastener comprising,
- a pressure-sensitive tape strip having a first end section secured to the back surface of the pad assembly with adhesive on the first end section being exposed through said opening means of the pad assembly, and a second securement end section extending past the side edge of the pad assembly, and
- a release sheet having a first surface providing a relatively low affinity for adhesive on said tape strip and a second surface facing the front surface of the pad assembly, with said adhesive exposed through the opening means being attached to the release sheet adjacent one end of the release sheet, said release sheet extending past the side edge of the pad assembly with the other end of the release sheet being attached to adhesive on the second end section of the tape strip adjacent the side edge of the pad assembly, said second end section of the tape strip being folded over and releasably attached to the first surface of the release sheet.
