ABSTRACT:
A device for containing sterile liquids in such a manner so that said liquid may be incrementally dispensed from the device without contamination to the remaining liquid. More particularly, a bottle having an opening and having within it a flexible plastic bag connected to the bottle only at its opening. Said bottle opening being sealed by a rubber stopper which has a vent in it which allows air to flow from outside the container to the area between the bottle and the flexible bag. Thus when liquid is sucked out of the bag via a hollow needle inserted through the stopper, no vacuum is created for the bag collapses as air flows into the area between the bag and bottle.
