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.
A disposable diaper of the type having a generally rectangular shaped absorbent pad disposed between a fluid-permeable cover sheet and a thin plastic backing sheet together with a pair of pressure-sensitive fastening tapes for securing the diaper about a person has the improvement comprising: a pair of cutout regions within the absorbent pad positioned at the corners thereof where said tapes are fixedly secured to said backing sheet; and means to bond together the regions of the cover sheet overlaying the backing sheet within the cutout regions into integral tape attaching bases to which a portion of said fastening tapes are attached, whereby tension exerted on the free end of a tape will be transferred, at least in part, to the cover sheet.
