Abstract
Abstract A drug testing urine sample collector includes a multiple tamper-proof system to make sure that freshly voided samples of urine are not replaced or adulterated. A chemical type thermometer is located in the reservoir to make sure that the urine sample is fresh when collected. A specific gravity sensitive ball valve restricts entry of a diluted urine sample into the reservoir. The cap for the reservoir also acts as a base for the collector and includes sample adulteration detection reagents. The collector structure prevents the sample from being emptied from the reservoir.

Independent Claim
260 words
A drug testing urine sample collection kit apparatus comprising: a reservoir having a cavity therein for holding a sample of urine; a collection means for collecting urine and transmitting it to said reservoir, said collection means including a bowl connectable to said reservoir, a tube connected to the bottom of said bowl and including a channel therein for communicating from said bowl into the cavity of said reservoir, said channel including a taper from a larger entrance aperture in the area of the bottom of said bowl to a smaller exit aperture near the discharge end of said tube; a sphere having a specific gravity in the range of 1.001 to 1.002 and located in said tapered channel wherein said sphere prevents liquid with a specific gravity of less than about 1.002 from passing into said reservoir; a keeper means for preventing said sphere from escaping from the large entrance aperture of said channel; air venting means in said bowl for permitting air to escape from said reservoir as it fills up with urine and for preventing any substantial amount of urine from escaping from said reservoir when said apparatus is inverted; and, a temperature detecting means for measuring the temperature of the urine as it is being collected in said reservoir and for providing an indication of the collection temperature for a prolonged period of time after collection, thereby serving as an indication that the sample was fresh and unadulterated when collected, wherein said tube prevents said urine from being emptied from said reservoir when said apparatus is inverted.
