ABSTRACT:
A disposable, one-piece cap for a liquid container includes a frangible septum which allows easy penetration by a syringe needle to permit withdrawal of the liquid. The septum includes a plurality of grooves which are thinner than the thickness of the remainder of the septum to facilitate tearing of the septum as the needle penetrates. Such tearing prevents a seal from forming around the needle and thus allows air to enter the container avoiding problems associated with the formation of a partial vacuum within the container as the sample is withdrawn.
