Abstract
Liquid dispensing devices provided with tilting or bending pickup tubes for allowing substantially complete evacuation of the contents of the supply bottles. In preferred embodiments, the pickup tube is connected to a dispensing unit such as a sprayhead by a variety of different types of flexible connectors to allow tilting of the pickup tube. In other preferred embodiments, a semi-flexible pickup tube is weighted to cause bending of the tube with or without the addition of a flexible connector between the pickup tube and sprayhead.
Claims20
A liquid dispensing device, comprising:
- a liquid container having an opening and bottom;
- a dispensing unit connected to said container at said opening;
- a pickup tube in the range of stiffness from semi-rigid to rigid connected to said dispensing unit and extending through said opening into said container, said pickup tube having a distal end and arranged so that said distal end moves in close proximity to said bottom of said liquid container to accommodate sway of the device during operation and enable substantially or complete evacuation of liquid stored in said liquid container.
A spray bottle, comprising:
- a liquid container with a neck and a bottom;
- a sprayhead with a pump mechanism having a suction chamber, said sprayhead connected to said neck of said liquid container;
- a pickup tube having a proximal end and a distal end, said proximal end of said pickup tube operationally connected to said suction chamber of said pump mechanism;
- and
- a flexible connector connecting said pickup tube to said suction chamber of said sprayhead to provide tilting of said pickup tube relative to said sprayhead to accommodate sway of the device during operation.
A flexible connector for connecting a pickup tube to a dispensing unit of a liquid dispensing device, said flexible connector comprising;
- first connector means for connecting said flexible connector to said pickup tube;
- second connector means for connecting said flexible connector to said dispensing unit;
- and
- a flexible connection means disposed between said first connector means and said second connector means for allowing tilting of the said pickup tube relative to said dispensing unit.
