Abstract
Abstract A throw-away receptacle for collection of urine of those confined to bed comprises a flexible bag of foil material associated with a non-return valve and a holder. Two sides of the bag are welded along two lines converging from the opening end of the bag without intersecting each other to provide a funnelshaped inlet. The non-return valve is inserted into and connected liquid-tight to the funnel-shaped inlet of the bag.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
248 words
A throw-away receptacle for the collection of urine of those confined to bed, comprising an elongated flexible bag of tubular foil material one end of which is closed and the other end of which is open, a nonreturn valve for insertion into the open end of said bag, and a comparatively rigid funnel-shaped holder for said bag and valve, said valve including a valve body comprising a sleeve having the same conicity as said holder whereby said sleeve may be wedged into said holder to secure said bag in place between the exterior of said sleeve and the iNterior of said holder, a perforated cover member extending across one end of said sleeve, a thin membrane disposed within said sleeve adjacent the inner surface of said cover member, a limited portion of said membrane being hingedly attached to said sleeve to permit said membrane to move toward and away from the perforations in said cover member thereby to control the passage of urine through said perforations, a disc-shaped member located within said sleeve between said membrane and the other end of said sleeve for free movement relative to said membrane whereby said member is operative to move said membrane toward said cover member to selectively close said perforations, and an apertured bottom structure extending across the other end of said sleeve for retaining said member within said sleeve while permitting the passage of urine past said member and through said other end of said sleeve into said bag.
Claim 2
Dependent Claim
248 words
A throw-away receptacle for the collection of urine of those confined to bed, comprising an elongated flexible bag of tubular foil material one end of which is closed and the other end of which is open, a nonreturn valve for insertion into the open end of said bag, and a comparatively rigid funnel-shaped holder for said bag and valve, said valve including a valve body comprising a sleeve having the same conicity as said holder whereby said sleeve may be wedged into said holder to secure said bag in place between the exterior of said sleeve and the iNterior of said holder, a perforated cover member extending across one end of said sleeve, a thin membrane disposed within said sleeve adjacent the inner surface of said cover member, a limited portion of said membrane being hingedly attached to said sleeve to permit said membrane to move toward and away from the perforations in said cover member thereby to control the passage of urine through said perforations, a disc-shaped member located within said sleeve between said membrane and the other end of said sleeve for free movement relative to said membrane whereby said member is operative to move said membrane toward said cover member to selectively close said perforations, and an apertured bottom structure extending across the other end of said sleeve for retaining said member within said sleeve while permitting the passage of urine past said member and through said other end of said sleeve into said bag.
Claim 3
Dependent Claim
128 words
The structure of claim 1 wherein said bag of foil material is welded along two lines extending partially into said bag from said open end to define a funnel-shaped inlet to said bag, said lines converging from the open end of the bag at an angle such that, when said open end is expanded to a circular cross section, the portion of said bag along said weld lines forms a conical surface having the same conicity as said holder, tranverse weld joints in said bag extending from the interior ends of said converging weld lines to the sides of said bag to seal the parts of the bag at the sides of said funnel-shaped inlet, said bag and the valve inserted therein being removably disposed within said holder.
Claim 4
Dependent Claim
15 words
The structure of claim 1 wherein said disc-shaped member is fabricated of foam plastic material.
Claim 5
Dependent Claim
23 words
The structure of claim 1 wherein said apertured bottom structure comprises a plurality of spokes extending across the other end of said sleeve.
