Abstract: An improved diaper fastener system has particular application to a conventional disposable diaper having a generally rectangular-shaped absorbent pad or filler disposed between a fluid-permeable top cover sheet and a thermoplastic film backing sheet. The fastener system is comprised of a pair of substantially conventional pressure-sensitive fastener tapes but having stress-accepting inserts traversing a certain distance between the release liner and a position on the fixed portion of the fastener tape. When the attachment portion of the tape is opened for use, the applied forces are at least partially accepted by the stress-accepting insert, transferring it through the release liner to the cover sheet which is stronger than the plastic film backing sheet.

Abstract: An improved diaper fastener system has particular application to a conventional 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 conventional pressure-sensitive fastening tapes but the fixed portions of the tapes are positioned to coincide with cutout regions within the filler material. The regions within the cover sheet and within the backing sheet that are coplaner with the cutout regions in the filler material are integrally joined together with either a heat sealed bond or by using an appropriate adhesive. The bonds between the backing sheet and the cover sheet in the regions where the tapes will be fixed to the diaper serve to better distribute forces exerted on the free ends of the tapes, particularly during the diapering process.
