ABSTRACT:
An automatic, power-driven appliance loosens screw type lids from jars of varying sizes and shapes. A vertically upright housing is placed upon a flat, supporting surface like a counter-top or the like. The lower housing base as a frictional pad for engaging the jar. A spaced apart, movable head is constrained for vertical movements within the container chamber defined by the housing. The head is lowered or raised by a motor driving a lead-screw system. A rotatable friction chuck mounted in the head contacts and rotates the lid to be loosened. The friction chuck comprises a hollow drive shaft and means for shining Laser light through it to center a container to be opened. The start button should be pushed after centering a jar within the housing chamber, whereupon an automatic opening sequence commences.
