Abstract:
Device (G) for dispensing liquids (1), especially medicinal liquids, from a mouthpiece aperture (2), the device comprising a piston-cylinder device operative as a pump, and threshold means;wherein the mouthpiece aperture is connected to a supply of liquid, by manual actuation of the piston-cylinder device (4) which allows the manual actuation only after an overload threshold has been exceeded, there being a restoring spring force assigned to the overload threshold; andwherein the piston-cylinder device defines a pump chamber, and said spring force is provided by a spring disposed outside the pump chamber for returning a pump piston of the piston-cylinder device to its position relative to a pump cylinder of the piston-cylinder device upon completion of the manual actuation; andwherein said threshold means operatively interconnects between said piston and said cylinder to establish said overload threshold.
