Patent attributes
An apparatus for collecting oral fluid, comprising a vial formed with an inner specimen receptacle for receiving the oral fluid. The open top of the vial is cylindrical and formed with threads on a portion of its outer surface adjacent its open top. The specimen receptacle is disposed within the vial, spaced along its length from the inner surface of the vial and has a closed bottom end and an open top end. The entire periphery of the receptacle top end is sealingly secured to the inner surface of the vial proximal to but spaced from the vial's open threaded end. The bottom end of the vial can be open and flat and extend beyond the closed end of the specimen receptacle to enable the vial to be set on a horizontal surface. A funnel is removably placed in the open top end of the vial and narrows to an inner neck fits within the open top end of the vial. An outer neck depends from the funnel to surround the inner neck and extend beyond the inner neck and beyond the threaded portion of the outer surface of the vial to provide protection for the threaded portion of the vial from contamination from collected oral fluid. A cap for the vial is retained securely inside an enclosure on the underside of a lid that frictionally but removably fits to the top end of the funnel.
