Handy fluid tube

Abstract

A handy fluid tube includes a tube having a top end and a bottom end, a first fluid, for example, medical fluid, alcohol or cosmetic fluid contained in the tube, a second fluid with high viscosity and high adhesive contained in the tube and forming a floating stopper to seal the bottom end of the tube, and a sealing cap fastened to the tube and movable relative to the tube between a first position to seal the top end of the tube for causing the second fluid to seal the bottom end of the tube and a second position to open the top end for letting the atmospheric pressure enter the tube.

1 . A handy fluid tube, comprising a tube having an inside wall, an outside wall, a top end and a bottom end, a first fluid contained in said tube, a second fluid having the characteristics of high viscosity and high adhesion contained in said tube to form a floating stopper to seal said bottom end in such a manner that when said top end is sealed, said second fluid seals said bottom end to prohibit flowing of said first fluid out of said tube through said bottom end; when said top end is opened to let the atmosphere pressure enters said tube, said second fluid is forced to adhere to the inside wall of said tube for enabling said first fluid to flow out of said tube through said bottom end, wherein said top end of said tube is detachably sealed with a sealing cap, said sealing cap being movable relative to said tube between a first position to seal said top end of said tube for causing said second fluid to seal said bottom end of said tube and a second position to open said second end for letting the atmospheric pressure enter said tube, said sealing cap having a plurality of rounded flanges kept in contact with said tube. 
     
     
         2 . The handy fluid tube as claimed in  claim 1 , wherein said sealing cap is capped on the outside wall of said tube to keep said rounded flanges in close contact with the outside wall of said tube. 
     
     
         3 . The handy fluid tube as claimed in  claim 1 , wherein said sealing cap is press-fitted into said tube to keep said rounded flanges in close contact with the inside wall of said tube.
