A self-resealing container cap configured to make a closing engagement with a container and a septum of elastomeric material supported in an opening defined by the cap periphery. The septum is puncturable by a blunt tip of an instrument such as a disposable plastic pipetter tip or a single use plastic laboratory transfer pipette having a tip width substantially greater than the thickness of a central portion of the septum. The septum is further configured to be substantially self-resealing against significant leakage of specimen liquid through the septum following withdrawal of the blunt tip from the punctured septum.

[ What is claimed is:] [1.] A self-resealing container cap puncturable by a tubular implement having a blunt ended tip of given tip width, comprising:a cap periphery of relatively inelastic material configured to make closing engagement with a container and an initially unbroken septum of elastomeric material supported in a hole defined in said cap periphery, said septum having an annular outer portion radially contained by said cap periphery and a circular depression centered in said outer portion, said circular depression diminishing in thickness from said outer portion to a central area of minimum thickness, said minimum thickness being less than the thickness of said annular outer portion, said septum being arranged, shaped and sized for returning to a condition substantially sealed against significant leakage of liquid from the container through said septum after said area of minimum thickness is torn by perforation with a blunt ended implement having a tip width substantially greater than said minimum thickness.
