<p>A liquid dispensing device consisting of a liquid container (12) having an opening and a bottom (18) with a dispensing unit connected to the container (12) at its opening. A pickup tube (14) having a preselected wall thickness is connected to the dispensing unit and extends into the container (12). The pickup tube (14) has a distal end (16) and is arranged so that the distal end moves in close proximity to the bottom (18) of the container (12) to accommodate tilt of the device during operation and enable substantial or complete evacuation of liquid stored in the liquid container (12). The pickup tube (14) is characterized by a section having a wall thickness substantially less than the preselected wall thickness of the remainder of the tube (14) to provide flexing of the pickup tube (14) in response to tilting of the dispensing unit during operation.</p> |
