Abstract: A novel actuating device (1) is described for use in combination with a pressurized packaging (6), which comprises an actuator head (2) having a discharge orifice (11), a discharge duct (3) which connects the discharge orifice with an entry port (4). The actuating device is provided for actuating a resilient biased valve means for dispensing the fluid from the fluid container (6) and further comprises an open piston (16) having at least an upper sealing lip (20) which is sealing towards an inner wall of the discharge duct (3). An inner rod (25) is attached to the open piston (16) having a free end (26; 53) for closing the discharge orifice (11). The open piston (16) is biased towards the discharge opening: The actuator head (2) comprises a lever (31) for actuating the open piston (16) towards the entry port of the discharge duct (3).

Abstract: The invention relates to a novel pump device for a fluid container for dispensing a fluid, which device has an operating element and a head part, wherein a piston-cylinder unit forming a pump chamber is provided between the operating element and the head part. An inlet valve is provided at the inlet of the pump chamber, and an outlet valve is provided at the outlet of the pump chamber, wherein the operating element has an outflow with an outflow opening. The outlet valve is also provided at the outflow, and the outflow opening forms a valve seat in such a way that the outlet valve closes the outlet opening from outside.
