Syphon tube

Abstract

[Object] Although the take-out of liquid from a container by means of syphon tube has a merit of requiring no special structure on the container, activation of siphon is complex, on the contrary. Location of a valve or like in a liquid take-out path for easy activation damages possibility of realization of compact or downsized structure, and increases risk of trouble. [Achieving Means] With a shape of a bent portion of a syphon tube, by adopting a dimension between inner wall portions excellent in capillary effect, there can provide a structure capable of activating siphon only by inclining a container with minimal configuration without locating any movable member.

1 . A syphon tube that takes out a liquid in a container, wherein a shape of a bent portion of a syphon tube contacting to an edge portion of a container has a distance between inner wall portions of the syphon tube of less than twice a capillary length of a liquid along a predetermined range, and when the container is inclined, siphon or practical siphon phenomenon is caused.
