METHOD AND DEVICE FOR DOSED DISPENSING OF A LIQUID FROM A CONTAINER

摘要

The invention relates to a method for dosed dispensing of a liquid from a container that is connected to an outflow channel that may be closed off by a liquid valve, comprising opening the liquid valve, dispensing a dose of the liquid from the container through the outflow channel and closing the liquid valve, and blowing empty the outflow channel after closing of the liquid valve. During dispensing of the liquid a pressure in the container may be higher than atmospheric pressure and the liquid valve may be biased to its closed position by this higher than atmospheric pressure in the container. The invention further relates to a device for dosed dispensing of a liquid from a container, comprising an outflow channel that can be connected to the container and that can be closed off by a liquid valve, and means for blowing empty the outflow channel when the liquid valve is closed. These blowing empty means can be adapted to connect the outflow channel with a source of gas under higher than atmospheric pressure when the liquid valve is closed.
