ABSTRACT:
The disclosure is of a novel closure for air evacuated tubular container and comprises a tubular body having flexible, elastic sidewalls, an open end, a closed end formed by a cannula-pierceable, flexible, elastic end wall having a concavo-convex configuration in cross-section and a flange disposed radially about the periphery of the open end. The novel closure structure takes advantage of the vacuum force in the container to maintain a gas-proof, hermetic seal, reduces the thickness required of the closure to maintain the hermetic seal and is easier to assemble in an air evacuated container. The disclosure is also of a novel method of assembling the closure of the invention in an air evacuated tubular container.
