Abstract
An economical and ergonomical three-part tube squeezer for collapsible tubes containing viscous fluids, the squeezer including an elliptically shaped housing, a shaft rotatably mounted in the housing and having a longitudinal slot therethrough to receive the end of a tube and wind the tube therearound, a key outside the housing on an end of the shaft, for winding the shaft, and a removable (friction-fit or threaded) locking piece on the other end of the shaft, outside the housing, for holding the structure in assembly. The tube squeezer is self-standing and operated while in the standing position or held in one's hand. The tube squeezer rolls up the collapsible tube by the key to dispense the viscous fluid contents upwardly when in the standing position. The tube squeezer can be disposed with the collapsible tube or reused with another tube.
Claims8
A three-part, ergonomical, self-standable tube squeezer device comprising:
- an elongated housing as a first part having opposite curvilinear sides separated by first and second flat sides, a flat top surface with a centered longitudinal slot, and an open flat bottom;
- said first flat side having a first aperture and said second flat side having a second aperture;
- an elongated shaft as a second part with a longitudinal slot coextensive in length and width with said centered longitudinal slot in said top surface, and having an integral winding key on a first end, said shaft being positioned to project the winding key from said first aperture and outside the housing;
- and
- a locking guard piece as a third part for fitting an opposite second end of the shaft for maintaining the position of the shaft within the housing, whereby a collapsible tube containing viscous liquid can be dispensed by inserting an end of the tube into the centered longitudinal slot in the housing and into the coextensive slot in the shaft to squeeze the viscous liquid from the tube by turning the key and winding the emptying tube around the shaft.
