1. A dose administering device, comprising, in combination: a closed end wall, a flexible, collapsible sidewall circumscribing said end wall, an outlet coupling at an end of said sidewall opposite said closed end wall, liquid and gas in said device, and plunger means with means to be position
1. A dose administering device, comprising, in combination: a closed end wall, a flexible, collapsible sidewall circumscribing said end wall, an outlet coupling at an end of said sidewall opposite said closed end wall, liquid and gas in said device, and plunger means with means to be positioned on an exterior of said device's flexible sidewall at a transition between the gas and the liquid to eject the liquid by constricting said sidewall. 2. The device of claim 1 wherein said plunger means includes means to sequester substantially all liquid in the fluid adjacent said outlet coupling. 3. A dose administering device, comprising, in combination: a closed end wall, a flexible, collapsible sidewall circumscribing said end wall, an outlet coupling at an end of said sidewall opposite said closed end wall, fluid in said device with liquid adjacent the outlet coupling and gas adjacent said closed end wall, and plunger means with means to be positioned on an exterior of said device's flexible sidewall at a transition between liquid and gas to eject liquid by constricting said sidewall, wherein said outlet coupling is formed as a luer coupling. 4. A dose administering device, comprising, in combination: a closed end wall, a flexible, collapsible sidewall circumscribing said end wall, an outlet coupling at an end of said sidewall opposite said closed end wall, liquid and gas in said device, and plunger means with means to be positioned on an exterior of said device's flexible sidewall at a transition between the gas and the liquid to eject liquid by constricting said sidewall, wherein said outlet coupling is formed as a spike. 5. A dose administering device, comprising, in combination: a closed end wall, a flexible, collapsible sidewall circumscribing said end wall, an outlet coupling at an end of said sidewall opposite said closed end wall, liquid and gas in said device, and plunger means with means to be positioned on an exterior of said device's flexible sidewall at a transition between the gas and the liquid to eject liquid by constricting said sidewall, wherein said outlet is configured as a conical taper narrowing from said sidewalls towards an axial centerline to frictionally overlie a luer coupling. 6. A dose administering device, comprising, in combination: a closed end wall, a flexible, collapsible sidewall circumscribing said end wall, an outlet coupling at an end of said sidewall opposite said closed end wall, liquid and gas in said device, and plunger means with means to be positioned on an exterior of said device's flexible sidewall at a transition between the gas and the liquid to eject liquid by constricting said sidewall, wherein said plunger means is embodied as a plurality of rollers straddling said device, including a tab projecting from said end wall of said device and retaining means located above and below said tab for grasping said tab to facilitate motion of said rollers with respect to said tab. 7. A medicinal dose administering device, comprising, in combination: a closed end wall, a flexible, collapsible sidewall circumscribing said end wall, an outlet coupling at an end of said sidewall opposite said closed end wall, medicinal liquid in said device along with gas, and plunger means with means to be positioned on an exterior of said device's flexible sidewall at a transition between the gas and the liquid to eject medicinal liquid by constricting said sidewall.
