ABSTRACT:
A closure for a medical specimen test jar includes a threaded closure ring and a separate, connected but freely rotatable sealing gasket on the underside of the ring. An agar paddle is secured to the closure via the gasket at the inside of the closure ring, the gasket material being relatively rigid, and the connection with the agar paddle being such as to retain the agar paddle securely. A matrix of posts is included on each side of the agar paddle, and in the production of the paddle the posts and a perimeter rim around each side of the agar paddle are staked down by heat and pressure to form overhanging flanges on the posts and an undercut rim which serve to retain the flexible agar mass in place on the test paddle. At the center of the closure is a needle-penetrable septum for receiving injection of blood or other specimens. The closure retains a vacuum in the medical specimen jar and still allows removal of the closure without requiring excessive twisting force, by use of the two-piece assembly, which eliminates the need to overcome static friction of the gasket on the container finish while unscrewing the closure ring.
