Abstract
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. The ball is capable of rotative movement between an open position and a closed position, with the passageway being aligned with the open end of the collection container when the ball is in an open position and being out of alignment with the open end of the collection container when the ball is in a closed position. The closure further includes a socket mountable on the open end of the collection container for accommodating rotative movement of the ball between an open position and a closed position. The socket includes an integral flexible seal which provides a perimetrical seat for the ball.
