PRESSURE-PULSE ACTUATED LIQUID DISPENSING APPARATUS

A liquid dispensing apparatus comprises a liquid reservoir ( 32 ), an outlet port ( 6; 36 ) and driving means for forcing liquid ( 4 ) through the outlet port ( 6, 36 ). The driving means generates a pulse of gas which impinges upon the liquid ( 4 ) in the reservoir ( 32 ) so as to force liquid ( 4...

More Information
Summary:A liquid dispensing apparatus comprises a liquid reservoir ( 32 ), an outlet port ( 6; 36 ) and driving means for forcing liquid ( 4 ) through the outlet port ( 6, 36 ). The driving means generates a pulse of gas which impinges upon the liquid ( 4 ) in the reservoir ( 32 ) so as to force liquid ( 4 ) through the outlet port ( 6, 36 ). Also disclosed is a cassette comprising a plurality of cartridges for dispensing liquid therefrom. Each cartridge comprises a liquid reservoir ( 32 ) and an outlet member ( 36 ) mounted so as to close an opening ( 34 ) in the liquid reservoir ( 32 ). The outlet member ( 36 ) provides an outlet port through which the liquid can be forced by a pulse of pressurised gas.
