ABSTRACT:
A liquid administration device comprises a flexible, collapsible bag for the liquid, an outlet tube communicating with the bag and a rigid housing enclosing the bag with the outlet tube projecting outwardly therefrom. Flexible, compressed cellular material is positioned within the housing, exerting pressure due to its compression on the bag which tends to urge the bag towards its collapsed position. Thus the liquid in the bag can be expelled through the outlet tube, with the flow governed by a valve, in a manner independent of gravity.
