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).
Claims18
A hand-held liquid injector system comprising a liquid injector, the liquid injector comprising a container for containing a liquid having an outlet, a manually operable piston slidable in the container and a valve member movable into and out of a closed portion for controlling flow of the liquid through the outlet from the container, the injector being arranged such that operation of the piston causes the liquid to be subjected to pressure whereby, when the valve member is operated, at least some of the liquid is transferred from the container under pressure in a controlled manner, the injector further comprising a stopper for limiting movement of the valve member inwards away from the closed position.
A hand-held liquid injector system comprising a liquid injector, the liquid injector comprising a container for containing a liquid having an outlet, a manually operable piston slidable in the container and a valve member for controlling flow of the liquid through the outlet from the container, the injector being arranged such that operation of the piston causes the liquid to be subjected to pressure whereby, when the valve member is operated, at least some of the liquid is transferred from the container under pressure in a controlled manner, the injector further comprising a stopper for limiting movement of the valve member, the system further comprising a nozzle for engaging the valve member.
A hand-held liquid injector system comprising a liquid injector, the liquid injector comprising a container for containing a liquid having an outlet, a manually operable piston slidable in the container and a valve member for controlling flow of the liquid through the outlet from the container, the injector being arranged such that operation of the piston causes the liquid to be subjected to pressure whereby, when the valve member is operated, at least some of the liquid is transferred from the container under pressure in a controlled manner, the injector further comprising a stopper for limiting movement of the valve member, the system further comprising a second container for receiving liquid from the injector wherein the liquid injector is combined with the second container.
A hand-held liquid injector systems comprising a liquid injector, the liquid injector comprising a container for containing a liquid having an outlet, a manually operable piston slidable in the container and a valve member for controlling flow of the liquid through the outlet from the container, the injector being arranged such that operation of the piston causes the liquid to be subjected to pressure whereby, when the valve member is operated, at least some of the liquid is transferred from the container under pressure in a controlled manner, the injector further comprising a stopper for limiting movement of the valve member, the system further comprising a cap for a second container, the cap having a secondary release outlet.
