A container cap or a liquid communication adapter attachable to a container mouth having a conventional rubber-like stopper, in which many repeated piercings do not cause degradation in the rubber-like stopper of a vial, that has less possibility of accidental pricks, can be engaged with a luer of a commonly used syringe, reliably can keep air-tightness with the syringe luer when the luer is connected, reliably can prevent liquid leakage when the luer is not connected, and further can allow an easy and reliable sterilization of a piercing site is provided. A container cap includes at least one disk-like valve (1) provided with an insertion hole (3) in a central portion thereof, and a cover (2) for restraining the valve (1) by covering at least an upper periphery of the valve (1). A lower periphery on a back surface of the valve (1) is supported by a seating portion of a container mouth or a seating portion of a joint (4) that is supported by the container mouth, and the container cap has an anchor means for anchoring an insertion member to the cap by using a peripheral edge forming a fitting hole (7) in the cover (2), while inserting the insertion member into the insertion hole (3). <IMAGE> |
