Abstract
A liquid dispenser device including a container for storing the liquid to be dispensed, a dispenser endpiece mounted on the container, being provided with a support and a liquid dispenser valve, the valve including an elastomer material and being capable of taking up a blocking configuration and a liquid-passing configuration by co-operating with the support, and a flowrate-reducer member including a liquid-deflector shape defining a flowrate-reducer channel, the flowrate-reducer member being a part that is separate from the support and separate from the valve.
Claims14
A liquid dispenser device comprising:
- a container for storing the liquid to be dispensed;
- a dispenser endpiece mounted on the container, being provided with a support and a liquid dispenser valve, the valve comprising an elastomer material and being capable of taking up a blocking configuration and a liquid-passing configuration by cooperating with the support;
- and
- a flowrate-reducer member comprising a liquid-deflector shape defining a flowrate-reducer channel, the flowrate-reducer member being a part that is separate from the support and separate from the valve;
- the support having a sealing portion with a bearing surface for blocking the passage of liquid in the blocking configuration, the sealing portion having a cylindrical shape and the bearing surface being disposed at a distal end of the sealing portion, and wherein the valve further includes a cylindrical portion covering the cylindrical shape of the sealing portion and cooperating with the cylindrical shape of the sealing portion to define a cylindrical channel there between and downstream from the flowrate-reducer member;
- wherein the flowrate-reducer member is cylindrical in shape, the liquid-deflector shape being made in an outer perihery of the flowrate-reducer member and comprising a helical groove.
