Abstract
A disposable diaper includes a sealable disposal envelope integrally attached along a belt area seam of the diaper. A sealing tape-belt member adhered to the envelope provides an airtight seal of this envelope when the used diaper is folded and then inturned around the seam and placed within the envelope. The seam is adherently formed, by among other possibilities, by a heat seal or adhesive such as a double stick adhesive tape. The sealing tape is also provided with an adhesive on both faces. One face of the sealing adhesive is attached to the inside of the envelope while the other face performs a dual function. Initially, this other face secures the opening of the un-used disposal bag in a closed manner but subsequently serves to sealingly close this bag opening following infolding of the used diaper into the attached disposal bag. During use of the diaper, the sealing tape operates as a belt, permitting form-fitting of the diaper about the body. In one embodiment, the belt area of the diaper has two slits and the tape ends extend through these slits. Protective strips on the double stick adhesive of the tape cover portions of the adhesive until ready for usage. With this arrangement, refastenable tabs are provided to allow form-fitting of the diaper during its use and additionally, adjacent adhesive portions are exposable after the diaper has been used, to permit the sealing of the disposal bag following insertion of the used diaper therewithin.
