ABSTRACT:
A canteen minimizes sloshing or gurgling in a container containing liquid, by mechanically displacing air in an internal plastic bag which contains the liquid. The canteen permits a user to reduce the air space within the plastic bag by turning a knob which is attached to a turnscrew, which, in turn, raises a platform, thereby compressing the bag. With the air displaced from the bag, the liquid does not slosh or gurgle when the canteen is moved. A locking assembly is provided to lock the thumbscrew in place.
