1. An apparatus for dispensing a liquid composition intended for parenteral administration comprising in combination a rigid container having an opening at one end and adapted to contain under pressure the liquid composition and a gas or liquified gas essentially insoluble in the liquid composition, a closure for the opening having a portion adapted to project into the dispensible liquid composition in the container, a valve within the closure for discharging the liquid composition from the container through the inwardly projecting portion of the closure to an outlet of the container, and a hypodermic syringe comprising a barrel of constant diameter having an opening at one end and terminating at the other end in a hollow filling tip hermetically engaged directly with the outlet of the container to form a fluid-tight conduit for the liquid composition from the outlet to within the barrel of the syringe and a plunger slideably disposed within the barrel and responsive to the pressure exerted by the liquid composition entering the barrel of the syringe.
