  • Dual-chamber liquid receiving and containing device
    Patent number: 7195602
    Abstract: A dual-chamber device for receiving and containing a liquid, particularly urine, employs a generally cylindrical body having a detachable top cover and an internal, transverse, funnel-shaped wall. The transverse wall has a central circular orifice and divides the body into lower and upper chambers for respectively receiving and retaining fore-stream and mid-stream urine liquid samples. A floatable orifice stopper in the lower chamber is responsive to fore-stream liquid filling the lower chamber to a predetermined level for closing the orifice, so that subsequent, mid-stream urine liquid is received into the upper chamber. An annular float beneath the orifice stopper assures proper stopper closing of the orifice. A bottom cover has an upstanding stopper pushing column and a flexible, spring-like, annular web adjacent the cover periphery.
