ABSTRACT:
A liquid injector system includes a liquid injector (10) comprising a container (11) for containing a concentrated liquid and having an opening (13) which is closed by a valve (23). The valve (23) is biased to a closed position by leaf springs (28) and is opened by engagement by a nozzle. Pressure is applied to the concentrated liquid by means of a manually operable piston (19) so that, when the valve (23) is in an open position, at least some of the concentrated liquid is dispensed under pressure from the container (11).
