Liquid dispenser

A liquid dispenser for discharging liquids, said liquid dispenser comprising:

• a reservoir configured to store liquid prior to discharge from said liquid dispenser;
• an applicator for delivering liquid into a surrounding area, said applicator comprising a porous application element for liquid take-up, said porous application element having an externally-located liquid-delivering side for delivering liquid to a target surface and a liquid take-up side;
• and
• an outlet channel connecting said reservoir to said applicator, said liquid take-up side of said porous application element being disposed to take up liquid supplied from said outlet channel, wherein:
• said outlet channel is configured as a valveless outlet channel creating a permanent connection between said reservoir and said applicator, and said applicator is also valveless;
• or
• said liquid dispenser includes a liquid outlet valve dependent on pressure for opening, said liquid outlet valve opening when there exists a sufficient minimum opening overpressure;
• said liquid dispenser further including a pressure generating device configured to pressurize liquid in said reservoir such that the liquid is conveyed through said outlet channel to said applicator, said pressure generating device having an air pumping device and an actuating pressure chamber fed by said air pumping device, said actuating pressure chamber adjoining said reservoir and being separated therefrom by a displaceable wall such that an overpressure in said actuating pressure chamber leads to an overpressure in said reservoir, said air pumping device having an actuator for manual actuation, said actuator allowing air to be pumped into said actuating pressure chamber such that the overpressure in said actuating pressure chamber and in said reservoir rises sufficiently to convey liquid from said reservoir to said applicator.
