  • Patent number: 3951149
    Abstract: An improved tape tab system for use in disposable diapers in which one end of a first strip of tape is adhesively attached to a diaper. A second strip of tape with one adhesive surface is attached to the free end of the first strip. A releasable cover strip protects the adhesive surface of the second strip. Upon diapering, the cover strip is removed from the adhesive surface of the second strip and the composite strips are fastened to an opposite corner of the diaper, the adhesive surface of the second strip making the original contact and diaper closure. The diaper may be opened for inspection or adjustment by peeling the first strip from the attached second strip, and then reclosed by repositioning the tapes in an overlapping relationship.
