Flexible tube liquid transfer device

A device for the transfer of liquids without a pump by simple hand movement comprising:

• first, second and third flexible tubes having first, second and third diameters respectively, said first diameter being greater than said second diameter and said second diameter being greater than said third diameter,
• said first, second and third tubes being substantially coaxial with one another,
• a coupling bush connecting a first end of said first tube and a first end of said third tube to position said third tube substantially coaxially within said first tube, said first and third tube defining an annular chamber therebetween,
• said second tube being positioned between said first tube and said third tube for axial movement between a telescoped position and an extended position,
• a sealing member at the second end of said first tube to provide a sealing engagement between said second end of said first tube and said second tube in all axial positions of said second tube,
• said second tube when in the telescoped position having a first end adjacent said coupling bush and a second end extending past said sealing member, and
• a removable air tight closure at the second end of said second tube,
• the end of said device adjacent said coupling bush being open solely to the interior of said third tube,
• the end of said device adjacent to said sealing member being closed by the joint action of said sealing member and said closure,
• whereby manual extension of said second tube after placing the first end of the device in a liquid medium will draw liquid into the third tube and permit siphoning of the fluid to occur upon flexing the device and upon manual removal of the closure after full extension of the second tube.
