Ball and socket closure for specimen collection container

摘要

A closure for sealing the open end of a specimen collection container from the environment is provided. The closure includes a generally spherical-shaped ball having a passageway extending therethrough, with the ball including an axle permitting rotative movement of the ball thereabout between an open position and a closed position. The closure further includes a socket mounted on the open end of the collection container, with the socket including a ball receiving internal surface having an axle-support for receiving the axle of the ball for accommodating rotative movement of the ball therein. The passageway of the ball is aligned with the open end of said collection container when the ball is in an open position and is out of alignment with the open end of the collection container when the ball is in a closed position. The axle-support of the socket and the axle of the ball are parallel and eccentric with respect to each other.
