Abstract
A tubular element for drawing liquid from a container is shown including 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. The tubular element is designed to pass through an orifice or an inlet conduit, made from an elastically extendable materia. The cross section of the tubular element is sized to be contiguous with the edge of the orifice or with the wall of the conduit. The tubular element also includes an annular bulge with a truncated cone shaped surface which includes a small base, which is directed towards the second end and has a diameter substantially equal to the external diameter of the said tubular element and which also includes a large base which with the external surface of the tubular element, defines a bearing surface and serves as an end stop with the conduit wall or the aperture of said container. The suction orifice of the second end of the tubular element is made through the small base of the truncated cone shaped surface of the annular bulge and forms a plane substantially perpendicular to the longitudinal axis of the tubular element.
