Title:
SIPHON TUBE
Document Type and Number:
WIPO Patent Application WO/2012/057062
Kind Code:
A1
Abstract:
[Problem]
Although there is an advantage in the extraction of liquid from a container by means of a siphon tube in that the container is not required to have a special shape, it is difficult to start the siphoning. When a valve or the like is provided in the liquid extraction path to facilitate the start of the siphoning, the ability to reduce the size is lost, and the risk of malfunction increases.
[Solution]
A minimal configuration that enables siphoning to start merely by tilting the container, by employing, for the interval between the inner walls in the curved portion of the siphon tube, dimensions with which the capillary effect predominates, without providing movable parts.
