Abstract
The invention is an apparatus which enables the operation of a dispensing assembly in a container containing fluid from either an inverted (upside-down), angles, or upright position. The apparatus serves as a fluid intake tube, and is fitted into the dispensing assembly of a container containing a fluid. The apparatus is composed to two generally tubular parts mounted concentrically: an outer tube, and an inner tube. On the outer tube, buoyant ring(s) are located, with confer buoyancy to the outer tube. The outer tube is slightly shorter than the inner tube. When the apparatus is fitted into a fluid-filled container, and said container is held in an inverted or downward-angled position, the perforations located at the end of the inner tube proximal to the dispensing assembly are exposed. The exposed perforations provide for uptake of fluid in the tube into the dispensing assembly of the liquid container. In an upright or upward-angled position, the perforations of the inner tube are covered and sealed by the outer tube, this allowing uptake of the fluid from the bottom of the apparatus into the dispensing assembly. The apparatus operates without a pressurized system, without piston…
