ABSTRACT:
An improved diaper fastener system has particular application to a disposable diaper having a generally rectangular-shaped absorbent pad or filler disposed between a fluid-permeable cover sheet and a thermoplastic film backing sheet. The fastener system is comprised of a pair of pressure-sensitive fastening tapes incorporaing a standard release liner with each tape. The improvement includes anchoring one surface of the fixed portion of the fastening tape of the bottom surface of the cover sheet and then adhesively bonding the other surface of the fixed portion to a folded-over side marginal portion of the backing sheet. The release liner is positioned atop the cover sheet and extends laterally a distance that corresponds with the lateral dimension of the attachment portion of the tape. When the tape fastener system is in its closed position, the attachment portion of the tape lies against the release liner and when it is in the open position, the attachment portion extends outwardly from the side edge of the diaper and any forces that are applied to the tape are then transferred to the top cover sheet which is stronger than the plastic film backing sheet.
