Keeping liq. sterile in container - involves wafer closure piece inside screw lid in which pin is fitted

摘要

The method of storing liqs. involves a container (1) closed by a watertight wafer-closure-piece (10) which can be pierced and which is contained in a screw-lid (4). Beneath the screw thread on the container (1) is a protuberance (3) forming a stop-piece for the edge (11) of the screw-top lid (4) in a first screwing position. The screw top (4) is made of elastic material so that when further screwed up its rim (11) is pushed over the protuberance (3) into a second screwing position. Inside the screw-top is a pin (9) the point of which lies above the wafer closure piece (10) in the first screwing position, and beneath the wafer-closure piece inside the container (1) in the second screwing position. USE/ADVANTAGE - A sterile liq. is contained in the container under seal and can quickly and easily be opened without changing the lid.
