  • Patent number: 4650483
    Abstract: A waste-containment garment such as a disposable diaper or a disposable diaper insert which is fitted with integrally protected adhesive fasteners which do not extend outwardly from the edges of the garment. Each adhesive fastener comprises a pressure sensitive adhesive means disposed on an outer surface of the garment and an adhesive-release means disposed adjacent thereto on the same outer surface of the garment. Preferably such means are disposed on corner areas of the garment, and the garment is folded to associate each adhesive means in face-to-face adhered relation with its adjacent adhesive-release means until immediately prior to use of the garment. To use the garment, each adhesive means is peeled from its associated adhesive-release means so that it may be used for its intended purpose: e.g., to secure a diaper insert inside a diaper or overpant or the like; or to secure the back corners of a disposable diaper to the adjacent front corners of the disposable diaper.

  • Patent number: 4578073
    Abstract: A composite waste-containment garment comprising a disposable, elasticized waste-containment insert secured by means integral with the insert inside a non-elasticized over-garment such as a conventional reuseable diaper, or a disposable diaper, or overpants, or the combination of a non-elasticized reuseable diaper covered with an outer-garment such as overpants having elasticized leg cuffs. The insert comprises an absorbent core and a liquid impervious backsheet. Preferably, it also includes a liquid pervious, hydrophobic topsheet. The insert has a width less than one-half the midsection girths of intended users and, preferably, the absorbent core has front and back waist portions which have widths of from about fifteen to about thirty-five percent of the midsection girths of intended users, or about one-quarter the midsection girth of nominally sized intended wearer.

  • Patent number: 4496360
    Abstract: A method of using a composite waste-containment garment comprising a disposable, elasticized waste-containment insert secured by means integral with the insert inside a non-elasticized over-garment such as a conventional reuseable diaper, or a disposable diaper, or overpants, or the combination of a non-elasticized reuseable diaper covered with an outer-garment such as overpants having elasticized leg cuffs. The insert is so elasticized along its longitudinal side edges that, when properly secured inside a suitable over-garment, and the over-garment is properly applied to a wearer, the elasticized side edges of the insert are sufficiently tensioned to form liquid seals or leg cuffs along upper thigh regions of the wearer: particularly, along the inner spans of the upper thigh regions of the wearer.
