ABSTRACT:
A ventible closure for a container adapted to hold sterile fluids wherein the container has a neck with an open end surrounded by a beaded rim. The closure includes a rigid plug which fits down into the container neck and an elastic cap fitting over the open end of the neck in engagement with the rigid plug and the beaded rim to seal the container. For venting, internal pressure within the container causes outward flexing of the elastic cap to break the seal and establish flow paths for the fluid to escape from the container.
