Abstract
A hand held, one touch jar opener can be placed on a jar and activated with a momentary touch of a button. An epicyclic gear train is set to sequentially provide a grip on a jar, and on a lid, followed by development of torque needed to move the lid in a counterclockwise direction with respect to the jar. The principles embodied in the opener shown can be realized in an opener which can be manually powered, or preferably motorised and possibly highly automated. A differential geartrain provides reduction of speed and increase in torque and then provides two balanced and opposing forces through the epicyclic gear assembly having sun and planet gears. This configuration enables a wide variety of screw-on lids and jars to be automatically closed to match the correct diameters, apply a gripping force and then apply torque in an opposing direction.
