Abstract
In a dispensing system such as a pressurized can or hand-pumped bottle, a liquid to be dispensed from a container flows through a composite dip tube that feeds an inlet of a liquid transfer device. The dip tube includes a straight dip tube that extends from the inlet to the bottom of the container and a U-shaped tube that extends from the inlet to the bottom of the container and then returns to the top of the interior of the container. The U-shaped tube acts as a siphon that, in combination with the conventional tip tube, provides liquid to the liquid transfer device when the container is upright, inverted, or oriented in any other position as long as one of the two open ends of the dip tube is in communication with the liquid.
