Abstract
A valved stopper insertable into the inlet passage of a urine bottle permits only unidirectional flow into the bottle to prevent accidental spillage. The stopper has a generally tubular body which retains a valve member. The valve member is free to move in the tube under gravitational influence. When the urine bottle is tilted or inverted the valve member moves toward the inlet opening and sealingly engages the inner surface of the tube to block off flow from the bottle.
Claims12
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.
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.
