<p>A device for dispensing a liquid comprising a tubular fitting member fitted to a mouth of a vessel storing the liquid, a dispensing pipe mounted to the fitting member, a bomb attachment communicating with the fitting member through a communication passage and holding therein a bomb filled with a propellant fluid, a bomb unstoppering needle fitted with a terminal sealing member therearound and mounted within the bomb attachment so as to be inserted into and withdrawn from a sealing plate of the bomb held within the bomb attachment, a supporting member for linearly movably supporting the unstoppering needle within the bomb attachment, and a device mounted rotatably in the bomb attachment and adapted for shifting the bomb attachment needle, is disclosed. The acute foremost part of the needle projecting beyond the sealing member pierces through the bomb sealing plate for forming a discharge orifice in the sealing plate for discharging the pressurized fluid from the bomb and thereby dispensing the liquid contained in the vessel. The dispensing device may also be provided with a valving member adapted to open or close a pressurizing fluid vent in timing with the operation of the needle shifting device in such a manner that the pressurizing gas in the vessel is discharged at the same time as the bomb is closed by the needle.</p> |
