ABSTRACT:
A unitary closure and delivery means for dispensing solutions for parenteral administration from containers having an open end with a constricted neck, comprising an outwardly directed portion extending from the constricted neck and an inwardly directed portion held in inwardly displaceable, sealable relation within said constricted neck. The outwardly directed portion is channeled with an axially directed bore. The inwardly directed portion has at least one axial bisecting division which extends to and communicates with the bore. The opposing surfaces of the division are normally separated, but when mated by compressive engagement of the divided parts while held within the neck form a liquid impermeable seal. When the unit is urged inwardly from the neck into the body of the container, the surfaces of the bisecting division separate to form a patent path of communication with the interior of the container and its contents.
