Fluid product dispenser with shunting chamber and governing device
First Claim
1. A dispenser for dispensing a fluid product, comprising a housing for accommodating an assembly, the assembly comprising:
- a liquid reservoir, for containing a liquid product;
a pump, connectable to the reservoir, for dispensing the fluid product using the liquid product as an input;
an outlet nozzle, serving to convey and dispense the fluid product from the pump;
whereby the pump comprises;
a liquid chamber, for containing a dose of the liquid product, obtainable from the liquid reservoir;
a pressurizing device, which allows liquid product to be drawn into or expelled from the liquid chamber,wherein the dispenser is further provided with a shunting chamber comprising;
a first aperture allowing flow access to the liquid reservoir;
a second aperture allowing flow access to the outlet nozzle;
a third aperture allowing flow access to the liquid chamber,the third aperture being disposed off-axis with respect to the first and second apertures, the shunting chamber further comprising a governing device that has two states, such that;
in a first state, a first flow path is created between the first and third apertures;
in a second state, a second flow path is created between the third and second apertures,and wherein;
the liquid chamber and pressurizing device are mounted as fixtures in the housing, and;
the liquid reservoir and outlet nozzle are removably mountable as disposable components in the housing.

Abstract
A dispenser includes a housing holding an assembly, including a liquid reservoir, a pump for dispensing the fluid product, and an outlet nozzle. The pump includes a liquid chamber for containing a dose of the liquid product and a pressurizing device which allows liquid product to be drawn into or expelled from the liquid chamber. The dispenser further includes a shunting chamber including a first aperture allowing flow access to the reservoir, a second aperture allowing flow access to the outlet nozzle, and a third aperture allowing flow access to the liquid chamber. The third aperture is disposed off-axis with respect to the first and second apertures. The shunting chamber further includes a mechanically actuated governing device that has two states, one defining a flow path between the first and third apertures and one defining a flow path between the third and second apertures.
