Abstract
Apparatus for dispensing metered quantities of liquefied gas such as liquid includes a thermally-insulated reservoir having at its bottom an outlet passage leading to a dispensing orifice outside the thermal insulator. There is a single valve for controlling admission of the liquefied gas to the dispensing orifice. The passage is in heat conductive relationship with a block of heat conductive material in the liquefied gas so as to maintain the passage sufficiently cold to prevent substantial evaporation of liquefied gas within the part of the passage with the reservoir. The valve may be cam or solenoid actuated to dispense drop of liquefied gas of chosen volume.
