FIELD: personal use articles. ^ SUBSTANCE: disposable pump for a system of liquids dispensing, in particular, for a dispensing system comprising a compressible reservoir comprises a body that forms a chamber and a hole for dispensing. In the chamber there is a controller fixed to control liquid flow between the reservoir and the chamber and between the chamber and the dispensing hole. The controller comprises an external valve for control of flow between the chamber and the dispensing hole. The external valve is installed with the possibility of displacement between the symmetrical position, which corresponds to the closed position of the pump, in which the external valve is in tight contact with the body, and the deviated position, which corresponds to the discharge position of the pump, in which the external valve is displaced from tight contact with the body depending on the chamber pressure. Displacement of the external valve from the symmetrical position into the deviated one requires external force applied to the pump and transferred to the controller no matter what the pressure changes in the chamber are. Also a system is provided for dispensing, as well as the method of liquid dispensing. ^ EFFECT: invention provides for convenience in use. ^ 16 cl, 20 dwg |
