Abstract

ABSTRACT OF THE DISCLOSURE
A tape strip assembly for a disposable diaper which has an absorbent pad between a backing sheet and a top sheet.
The tape strip assembly includes a base tape with a first adhe-sive securing a portion of said base tape to the backing sheet.
A releasable strip is secured by second adhesive means to the base tape with a third adhesive being on the releasable strip so that after initial attachment of the releasable strip to the backing sheet after first positioning on the user, the releasable strip can be peeled from the base tape to allow repositioning of the diaper.

BACKGROUND OF THF INVENTION
FIELD OF THE INVENTION

Thls invention relates to dlsposable dlapers or the like and Gore particularly to a tape strip assembly for enabling repositioning of a diaper on an infant ~sa~
In the past dlapers of various types haze been produced employlng an absorbent pad between a top sheet and a backing sheet formed of htwei~ht waterproof materlal such as polyethylene Tape strlps hAving sel~-stick pressure sensitive type adhesires ore used for ~asten~ng the dipper on an infant. When the tape strlp ls adhered to to backing strlp, it is often difficult to ra~ove wlthout tearing the backing sheet so as to permit reposi~
tionln~ ox a poorly ~itt~d diaper or reuse ox the diaper when wound to be lmsoiled~
Previously varlous expedients hove been used in an attempt to overcome the ~ores~d dl~l¢ult~esO To thls end the baeklng sheet has been mada ox a heavier grade polyethylene sheet but not only has thus proven too e~penslve~ but the heavier grade b~ckin~ sheet has rendered the diaper less plla~le ana com~ortabl~
to the userO
e~ker adhesives have been utlllzed 9 but thls has the dlsa~vanta~e that the diaper may Hall ox upon ~trenuolls movem2nt ox the user3 ~2~

~2~r'.11J56i Accordingly, the present invention overcomes the dis-advantages of -the prior problem solutions by providing or a diaper tape strip assembly renderiny the diaper repositionable and reuseable.

SUMMARY OF THE INVENTION
. . .
The present invention provides a tape strip assembly for a disposable article having a backing sheet, said tape strip assembly including a base tape, first adhesive means securing a portion of said base tape to said backing sheet, a releasable strip, second adhesive means securing said releasable strip to said base tape, and third adhesive means on said releasable strip for attachment of said releasable strip to ano-ther por-tion of said diaper, said diaper including an absorben-t pad on said backing sheet, and a top sheet overlying said absorbent pad, a release sheet on said top sheet, said tape strip assembly being folded over so that said third adhesive means removably secures said -tape strip assembly to said release sheet until positioning of the diaper about an infant, said second adhesive means having less adhesive affinity for said releasable strip than said third adhesive means has for said backing shee-t, said third adhesive means having less affinity for said release sheet than said second adhesive means has for said releasable strip, said second adhesive means having less affini-ty for said releasabl.e strip than said third adhesive means has for said backing sheet so that after ini-tial use said releasable strip acts to release said base tape and said second adhesive means for Eurther positioning on an infan-t.

BRIEF' DESCRIPTION OF TEE DRAWING
Figure 1 is a partial plan view of a diaper employing -the tape strip assembly according to the present inven-tion; and, Figure 2 is a sec-tional view taken along -the plane of line 2-2 in Figure 1.

S~i6 In use, the tape strip assembly is employed to Eas-ton the diapcr on the infant. Should the diaper be poorly positioned or desired to bo reused because it is unsoiled the lesser afEinity of the adhesive 26 -Eor the release strip 28 than the adhesive 30 for -the release strip 28 or the backing sheet 16 will permit peeling of the release strip 28 :Erom the adhesive 26 not only facilitating removal of the diaper without tearing of the backing sheet but also permitting reuse ox the diaper with base tape 22 and adhesive 26 as the new tab for securement purposes.

Claims

THE EMBODIMENTS OF THE INVENTION IN WHICH AN EXCLUSIVE
PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:
1. A tape strip assembly for a disposable article having a backing sheet, said tape strip assembly including a base tape, first adhesive means securing a portion of said base tape to said backing sheet, a releasable strip, second adhesive means securing said releasable strip to said base tape, and third adhesive means on said releasable strip for attachment of said releasable strip to another portion of said diaper, said diaper including an absorbent pad on said backing sheet, and a top sheet overlying said absorbent pad, a release sheet on said top sheet, said tape strip assembly being folded over so that said third adhesive means removably secures said tape strip assembly to said release sheet until positioning of the diaper about an infant, said second adhesive means having less adhesive affinity for said releasable strip than said third adhesive means has for said backing sheet, said third adhesive means having less affinity for said release sheet than said second adhesive means has for said releasable strip, said second adhesive means having less affinity for said releasable strip than said third adhesive means has for said backing sheet so that after initial use said releasable strip acts to release said base tape and said second adhesive means for further positioning on an infant.
