ABSTRACT:
A container for retaining a liquid sample to be tested is closed by a removable closure cap having a slot therein to receive a flat rectangular panel test card member inserted through the slot into the container. A flexible resilient member is mounted adjoining to the closure cap slot and has a slit therein with abutting edges through which the test card is passed. After the test card has been withdrawn, the abutting edges contract to their normally closed position to prevent the leakage of any liquid through the slot when the container is being handled. During withdrawal of the test card through the slot the abutting edges wipe excess liquid sample from the test card.
