ABSTRACT:
The present invention is generally a flexible tubing to use in such devices as spray bottles, toxic containers, pick up tubes used in medical applications, and in containers in fast food restaurants so that any fluid in the bottom of the container could be immediately and virtually completely removed. The tubing is shaped to conform generally to the bottom of the container, generally in a partial elliptical configuration in a horizontal plane. The tubing or pick up device comprises two parts, normally integrally joined, or fabricated as one piece. More specifically, the upper section of the pick up device is generally vertical, while the lower section is generally in an elliptical configuration. Multiple embodiments exist, including using materials such as rubber, plastic, or metal.
