发明名称 Pump dispenser with threshold actuation and restoring spring
摘要 A device (G) for dispensing liquids (1), especially medicinal liquids, from a mouthpiece aperture (2), the latter being connected to a supply of liquid, by manual actuation of a piston-cylinder device (4) which allows the manual actuation only after an overload threshold (Ü) has been exceeded. The device achieves a design which is advantageous for use, and provides a powerful jet of liquid, by a smaller restoring spring force, assigned to the overload threshold (Ü), of the piston-cylinder device (4) designed as a pump (P).
