Disposable pump for disinfectants, has one-way valve opened by low pressure developed in bottle, so that air flows through air inlet, vent pipe and pipe in bottle, and pump is used for evacuated bottles and for ventilated bottles
The pump has an one-way valve (4) opened by low pressure developed in a bottle (11), so that air flows through an air inlet (2), a vent pipe (9) and a pipe (1) in the bottle. The air inlet is provided in direct proximity of an outlet opening (10) in an ideal manner, so that the sucked air is disinfected by an output medium i.e. disinfectant, before inflow of the air into the bottle. The air inlet lies indirectly besides sealing edges (3) between an upper pump body with an inlet valve (5) and a bellows pump (6). The pump is used for evacuated bottles and for ventilated bottles.
