ABSTRACT:
The invention disclosed is an integral attachment for a container filling device which comprises a filling head having a tubular closure adapted to be opened when the filling head is inserted into the container to be filled, and an annular member functioning as a container closure member and having a central opening slightly larger than the tubular closure, an upper annular member spaced from the first annular member and integrally connected thereto by a resilient tubular member, the upper annular member having a close fit with the tubular closure in order to hold the attachment in place when it is slid onto the tubular closure, at least one vent aperture extending through the lower annular member with its vent end opening in the upper surface thereof in a position where it is adapted to be closed by the upper annular member when the resilient tubular member is collapsed by pushing the lower annular member upward into contact with the upper annular member, and the annular members having an island of surface-to-surface contact surrounding each vent end opening. These islands are comprised of raised portions having an upper surface which seals against a complementary surface of the upper annular member. Additional raised portions cooperate with the first raised portions to form pressure points and the lower annular member has an annular inlay extending outwardly from under these pressure points.
