<p>The current invention relates to a dispenser for liquid products comprising
- a removable liquid holding reservoir,
- an essentially rigid chamber (20,120) for holding liquid under pressure and comprising a spring (22,122) and a piston (24,124) to place liquid injected into said chamber (20,120) under pressure,
- a pump arrangement 930,130) for pumping liquid from the liquid holding reservoir into the said chamber (20,120) for holding liquid under pressure,
- the pump (30,130) being connected to the chamber (20,120) through a one-way valve (32,132) preventing liquid to flow from the chamber (20,120) back into the pump arrangement (30,130),
- the chamber (20,120) being connected to a spray nozzle (40,140) through a valve (42,142) controllable by the user for spraying said liquid.</p> |
