A bottle is provided having a mouth portion having an inner surface and an outer surface. The outer surface has at least two threads disposed thereon corresponding to the threads disposed on the inner surface of the side wall of the cap, so that when the cap is screwed on to the mouth of the bottle, a compression seal is formed along an entire circumference of the cap and the bottle with less than a full turn of the cap.
RELATED APPLICATIONS
This application is a divisional application of Applicant's co-pending U.S. patent application Ser. No. 09/652,737, entitled, "Removable Cap Assembly", filed on Aug. 31, 2000, the entirety of which is incorporated herein by reference.
A collection system for collecting, testing and transporting liquid biological specimens that limits exposure of a tester to the liquid sample and keeps the collected samples pristine even after exposing some of the sample to test strips. The system includes a collection body for receiving and holding a liquid sample, a lid that is coupled to the body, and a test strip housing. The lid includes a transfer conduit while the test strip housing includes an opening defined within the test strip housing. The transfer conduit and the opening are aligned when the test strip housing is coupled to the lid. When the system is moved or tilted, some of the liquid sample moves through the transfer conduit and the opening into the test strip housing.
