Claim 1

Independent Claim 153 words

A waste retaining receptacle for adhering to the body of a user to collect body waste issuing from the user's body via a stoma or similar orifice, said receptacle including an inlet aperture for waste, seal means surrounding said aperture for sealingly being adhered to the user's body around the stoma, said seal means comprising two laminae of relatively thin material bonded one to each side of a flexible annular ring resiliently deformable non-viscous material having a thickness substantially greater than the thickness of said laminae, one of the laminae being attached to the receptacle around said inlet aperture, and the other lamina being adapted to be adhered to the user's body around the stoma, said laminae extending each a substantial distance beyond the periphery of said flexible ring and bonded to one another over a substantial surface area at least around a major portion of the periphery of said flexible ring sheet.

Claim 2

Dependent Claim 153 words

A waste retaining receptacle for adhering to the body of a user to collect body waste issuing from the user's body via a stoma or similar orifice, said receptacle including an inlet aperture for waste, seal means surrounding said aperture for sealingly being adhered to the user's body around the stoma, said seal means comprising two laminae of relatively thin material bonded one to each side of a flexible annular ring resiliently deformable non-viscous material having a thickness substantially greater than the thickness of said laminae, one of the laminae being attached to the receptacle around said inlet aperture, and the other lamina being adapted to be adhered to the user's body around the stoma, said laminae extending each a substantial distance beyond the periphery of said flexible ring and bonded to one another over a substantial surface area at least around a major portion of the periphery of said flexible ring sheet.

Dependent Claim 23 words

A waste retaining receptacle as recited in claim 1, wherein said flexible ring is formed of material having the deformation characteristics of rubber.

Claim 4

Dependent Claim 17 words

A waste retaining receptacle as recited in claim 1, wherein said flexible material is a foam material.

Claim 5

Dependent Claim 17 words

A waste retaining receptacle as recited in claim 2, wherein said flexible material is a foam material.

Claim 6

Dependent Claim 29 words

A waste retaining receptacle as recited in claim 1, wherein said flexible material is a porous material adapted to allow passage of air but to prevent egress of liquid.

Claim 8

Dependent Claim 154 words

A waste retaining bag for adhering to the body of a user to collect body waste issuing from a stoma or similar orifice, said bag including first and second sheet members sealingly attached together around their peripheries to provide a fluid reservoir, one of said sheet members including an aperture defining an inlet for body waste, said inlet including a seal arrangement comprising a first lamina having an aperture generally matching that of the inlet and being secured to said inlet, a second lamina adapted for adhering to the body of a user, and a relatively resiliently deformable annular ring interposed between said laminae and having a thickness substantially greater than the thickness of said laminae, said first and second laminae extending each a substantial distance beyond the periphery of said ring and bonded to one another over a substantial surface area at least around a major portion of the periphery of said ring.

Claim 9

Dependent Claim 154 words

A waste retaining bag for adhering to the body of a user to collect body waste issuing from a stoma or similar orifice, said bag including first and second sheet members sealingly attached together around their peripheries to provide a fluid reservoir, one of said sheet members including an aperture defining an inlet for body waste, said inlet including a seal arrangement comprising a first lamina having an aperture generally matching that of the inlet and being secured to said inlet, a second lamina adapted for adhering to the body of a user, and a relatively resiliently deformable annular ring interposed between said laminae and having a thickness substantially greater than the thickness of said laminae, said first and second laminae extending each a substantial distance beyond the periphery of said ring and bonded to one another over a substantial surface area at least around a major portion of the periphery of said ring.

Claim 10

Dependent Claim 43 words

A waste retaining bag as recited in claim 7 wherein the inlet is provided in the upper portion of said one sheet member and said first lamina is attached to a region of said one sheet member adjacent the upper end region thereof.
