Abstract:
A tubular element for drawing liquid from a container, comprising, a first end designed to be connected to a source of vacuum and a second end designed to be immersed in the liquid to be drawn, said tubular element being designed to pass through an orifice or an inlet conduit, made from elastically extendable material, of said container, wherein the cross section of said tubular element being sized to be contiguous with the edge of said orifice or with the wall of said conduit, said tubular element includes an annular bulge with a truncated cone shaped surface wherein a small base, which is downwardly directed towards the second end, has a diameter substantially equal to the external diameter of said tubular element and wherein the diameter of a large base and the external surface of the tubular element define a bearing surface, serving as an end stop with the conduit wall or the aperture of said container, wherein the suction orifice of said second end of the tubular element is made through the small base of said truncated cone shaped surface of said annular bulge and forms a plane substantially perpendicular to the longitudinal axis of said tubular element.
