ABSTRACT:
An elastic plug assembly is provided for selective penetration by a needle. The elastic plug assembly comprises an elastic plug that is retained in a radially compressed state by a rigid plug retainer. The combined elastic plug and rigid plug retainer may be secured in a housing formed from an elastomeric material. The elastic plug may be penetrated by a needle. Upon removal of the needle, the radially compressed elastic plug will be urged toward its compressed condition with the space that had been occupied by the needle being completely filled to effectively achieve the sealing function of the plug. Needles may repeatedly be penetrated through the plug and removed as necessary, and the plug will efficiently return to its substantially solid sealed state after each successive needle removal.
