A method and apparatus for applying a fluid onto a number of surfaces. The apparatus comprises a structure, an applicator associated with the structure, a first control device associated with the structure, and a second control device associated with the structure. Applying a first force to the first control device causes the applicator to move relative to a center axis of the applicator. Applying a second force to the second control device causes the fluid to be delivered from a fluid dispensing system to the applicator.

A discharging device for liquids. The invention relates to a discharging device for liquids, more particularly for pharmaceutical liquids, comprising a delivery device (10), a liquid storage receptical (20) communicating with an input (10a) of the delivery device for storage of the liquid (30), and a discharge orifice (12) which communicates with an outlet (10b) of said delivery device, and the liquid storage receptical (20) is at least in part in the form of a dimensionally flexible liquid-containing bag (20) and the liquid storage receptical (20) is disposed in a buffer chamber of constant volume (42). To prevent air from escaping from the buffer chamber (42), provision is made for the buffer chamber to be sealed by a protective housing from the environment (1) in a gas-tight manner, for the buffer chamber to communicate with the environment through at least one capillary passageway for the purpose of pressure compensation, or for the buffer chamber (42) to communicate with the environment (1) via a balancing passageway for the purpose of pressure compensation, while a valve (70) which opens in dependence on the pressure differential is disposed in this balancing passageway.

A foam pump including a housing and a piston that reciprocates within the housing is disclosed herein. The piston has a hollow portion and an orifice through the wall of the piston. A first seal located proximate the upper end of the piston provides a seal between the piston and the housing. A liquid inlet is located in the side wall of the housing at a point lower than the top of the piston. A one-way liquid inlet valve is located proximate the liquid inlet and a one-way liquid outlet valve is located prior to the liquid outlet. A charge chamber is defined at least in part by the liquid inlet valve, the liquid outlet valve, a wall of the piston and a wall of the housing.
