2109606 9220449 PCTABS00017 A stopper (12) for hermetically sealing a container (10) containing a liquid sample is provided with an annular body (14) which defines a cavity open at the top end of the stopper. The annular body has upper walls (26) which abut against the inner surface of a container (22) when the stopper (12) is placed in the mouth of the container and downwardly extending lower walls (28) which are spaced from the sides of the container (10) and which define a normally closed slit (32) at the bottom end thereof. The lower walls (28) are connected to flexible but hollows pring elements (34) adapted to abut against the inner wall of the container when the stopper (12) is in the mouth of the container. The spring elements (34) are positioned on opposite sides of the lips (30) so as to flex inwardly toward the interior hollow space when an object pierces the slit opening (32).
