Abstract
A dispenser has a pump assembly with a housing (16) containing a pump (18,19) reciprocatably driven by a pump head (12) to pump liquid from the inlet to the outlet (45) of the pump. A spout (28) extends from the housing (16) and has a dispenser outlet (26). Due to the reciprocation of the pump (18,19) the pump outlet (45) moves relative to the dispenser outlet and to permit such movement they are interconnected by a flexible tube (24). The dispenser may also have a container for containing the liquid to be dispensed.
Claims9
A pump assembly for a pump action liquid dispenser, the assembly having:
- a pump comprising a pump chamber and a piston reciprocatable within the pump chamber so as to pump liquid between a pump inlet and a pump outlet, the pump being mounted in a housing;
- a pump head reciprocatable relative to the housing so as to cause the piston to reciprocate relative to the pump chamber, the pump outlet moving with the pump head;
- a dispenser outlet;
- and
- a flexible tube connectable between the pump outlet and the dispenser outlet, relative movement between the pump outlet and the dispenser outlet being accommodated by the flexible tube.
A pump action liquid dispenser comprising:
- a pump comprising a pump chamber and a piston reciprocatable within the pump chamber so as to pump liquid between a pump inlet and a pump outlet, the pump being mounted in a housing;
- a pump head reciprocatable relative to the housing so as to cause the piston to reciprocate relative to the pump chamber, the pump outlet moving with the pump head;
- a dispenser outlet;
- a flexible tube connectable between the pump outlet and the dispenser outlet, relative movement between the pump outlet and the dispenser outlet being accommodated by the flexible tube;
- and
- a container for containing a reservoir of liquid to be dispensed, the pump being in communication with the interior of the chamber to pump liquid therefrom.
