NOVEL LIQUID DISPENSING DEVICE AND METHOD OF MAKING SAME

摘要

A liquid dispensing device consisting of a liquid container (12) having an opening and a bottom with a dispensing unit connected to the container at its opening. A pickup tube (14) having a preselected wall thickness is connected via a coupling (214) to the dispensing unit and extends into the container. The pickup tube has a distal end and is arranged so that the distal end moves in close proximity to the bottom of said container to accommodate tilt of the device during operation and enable substantial or complete evacuation of liquid stored in the liquid container. The pickup tube is characterized by a section (22) having a wall thickness substantially less than the preselected wall thickness of the remainder of the tube to provide flexing of the pickup tube in response to tilting of the dispensing unit during operation. The coupling has a branch tube (218) in which is mounted a one-way valve to enable the dispensing device to be inverted and operated through 360 degrees.
