Valved stopper for a urine bottle

Claim 2

A valved stopper for a urine bottle of the type having a container body and an inlet extending from the container body and in communication therewith, comprising: a tubular body having an upper segment adjoining a lower segment, the upper segment being dimensioned at its uppermost portion to be closely received in the inlet opening to provide a close fit therein, the lower segment being tapered outwardly from the point of juncture with the upper segment; means for retaining the tubular body within the bottle inlet; and a gravity controlled valve member, having a hollow tapered shape complementary to the lower segment and open at its lower end, freely disposed within the lower segment and retained therein by stop means on the lower segment, the valve member being adapted to sealingly engage the inner surface of the lower segment when directed toward the inlet opening and thereby block flow from the bottle, whereby the open lower end of said valve member is adapted to receive liquid escaping from within said bottle to urge said valve member into sealing engagement with said inner surface and act to trap said liquid and prevent escape thereof.

Claim 3

The valved stopper as defined in claim 1, wherein the means for retaining the tubular body within the bottle inlet comprises an outward flange formed adjacent the upper edge of the upper segment.

Claim 4

The valved stopper as defined in claim 2, further including a matrix of resilient material surrounding the upper portion of the upper segment and the outward flange.

Claim 5

The valved stopper as defined in claim 3, wherein the matrix of resilient material is molded vinyl.

Claim 6

The valved stopper as defined in claim 3, wherein the upper segment is in the form of an inverted frustum.

Claim 7

The valved stopper as defined in claim 5, wherein an external groove is formed in the outer surface of the upper segment adjacent the outward flange to secure the matrix of resilient material in position.

Claim 8

The valved stopper as defined in claim 1, wherein the upper surface of the valve member is substantially convex to outwardly deflect incoming fluid and thereby reduce splashback.

Claim 9

The valved stopper as defined in claim 1, further including a plurality of scallops formed in the lower edge of the valve member to improve ventilation of air displaced by fluid entering the bottle.

Claim 10

The valved stopper as defined in claim 1, wherein the lower segment is in the form of a frustum.

Claim 11

The valved stopper as defined in claim 1, wherein the stop means comprises a plurality of tabs formed on the lower edge of the lower segment and extending radially inwardly therefrom.

Claim 12

The valved stopper as defined in claim 1, wherein the stopper is formed of styrene plastic.

Claim 13

A valved stopper for a urine bottle of the type having a container body and an inlet extending from the container body and in communication therewith, comprising: a tubular body having an upper segment shaped in the form of an inverted frustum adjoining a lower segment, the upper segment being dimensioned at its uppermost portion to be closely received in the inlet opening to provide a close fit therein, the lower segment shaped in the form of a frustum and being tapered outwardly from the point of juncture with the upper segment; means for retaining the tubular body within the bottle inlet comprising an outward flange formed adjacent the upper edge of the upper segment; a matrix of resilient material surrounding the upper portion of the upper segment and the outward flange and an external groove formed in the outer surface of the upper segment adjacent the outward flange to secure the matrix of resilient material in position; and a gravity controlled valve member, having a hollow, tapered shape complementary to the lower segment and open at its lower end and formed with a convexly shaped upper surface, freely disposed within the lower segment and retained therein by stop means comprised of a plurality of tabs formed on a lower edge of the lower segment, the valve member being adapted to sealingly engage the inner surface of the lower segment when directe toward the inlet opening and thereby block flow from the bottle, whereby, the open lower end of said valve member is adapted to receive liquid escaping from within said bottle to urge said valve member into sealing engagement with said inner surface and act to trap said liquid and prevent escape thereof.

Claim 14

A valved stopper for a urine bottle of the type having a container body and an inlet extending from the container body and in communication therewith, comprising: a tubular body having an upper segment shaped in the form of an inverted frustum adjoining a lower segment, the upper segment being dimensioned at its uppermost portion to be closely received in the inlet opening to provide a close fit therein, the lower segment shaped in the form of a frustum and being tapered outwardly from the point of juncture with the upper segment; means for retaining the tubular body within the bottle inlet comprising an outward flange formed adjacent the upper edge of the upper segment; a matrix of resilient material surrounding the upper portion of the upper segment and the outward flange and an external groove formed in the outer surface of the upper segment adjacent the outward flange to secure the matrix of resilient material in position; and a gravity controlled valve member, having a hollow, tapered shape complementary to the lower segment and open at its lower end and formed with a convexly shaped upper surface, freely disposed within the lower segment and retained therein by stop means comprised of a plurality of tabs formed on a lower edge of the lower segment, the valve member being adapted to sealingly engage the inner surface of the lower segment when directe toward the inlet opening and thereby block flow from the bottle, whereby, the open lower end of said valve member is adapted to receive liquid escaping from within said bottle to urge said valve member into sealing engagement with said inner surface and act to trap said liquid and prevent escape thereof.
