Abstract: The current invention relates to a dispenser for liquid products comprising a removable liquid holding reservoir, an essentially rigid chamber for holding liquid under pressure and comprising a spring and a piston to place liquid injected into the chamber under pressure, a pump arrangement for pumping liquid from the liquid holding reservoir into the chamber for holding liquid under pressure, the pump being connected to the chamber through a one-way valve preventing liquid to flow from the chamber back into the pump arrangement, the chamber being connected to a spray nozzle through a valve controllable by the user for spraying the liquid.

Abstract: A closure (1) for a container carrying a liquid comprises a first body (2) and a second body (3) mounted rotatably onto said first body, and a valve. The valve opens and closes by the action of tabs slidingly rotating over apertures provided in a member arranged transversely in a substantially cylindrical opening.

Abstract: The present invention is related to a battery-operated liquid dispensing device comprising a valve which is operated by the trigger (4), and which comprises a valve body (22) with a resilient dome-shaped portion (24), which closes off the valve by being biased against the valve seat (25). By pulling the trigger, the dome-shaped portion (24) is pushed away from the seat, thereby creating a passage for the liquid to pass to a gear pump (13) and nozzle (5).
