Siphon tube

Abstract

A siphon tube which is mounted on the brim of a container to take a liquid out from the container, includes a flow path, of which one end is immersed in the liquid inside the container and of which the other end extends to a position outside the container lower than a liquid level assumed; a relay liquid tank joining with the other end of the flow path; a takeout tube, of which one end joins with the relay liquid tank and of which the other end has an outlet at a position higher than the liquid level assumed; and a pumping device which generates a negative pressure inside the flow path. After establishing siphon or pressure siphon state with the liquid lead into the flow path by the pumping device, the siphon tube and the container are inclined together to take out the liquid.

1 . A siphon tube which is mounted on the brim of a container to take a liquid out from the container, the siphon tube comprising:
 a flow path, of which one end is immersed in the liquid inside the container and of which the other end extends to a position outside the container lower than a liquid level assumed;   a relay liquid tank joining with the other end of the flow path;   a takeout tube, of which one end joins with the relay liquid tank and of which the other end has an outlet at a position higher than the liquid level assumed; and   a pumping means which generates a negative pressure inside the flow path,   wherein, after establishing siphon or pressure siphon state with the liquid lead into the flow path by the pumping means, the siphon tube and the container are inclined together to take out the liquid.
