Abstract
An apparatus for loosening threaded lids from jars or similar containers having screw-type lids. The apparatus includes a rotatable bottom support platform having a friction pad for supporting and rotating the container, and a top, vertically movable friction pad for engaging the threaded lid whereupon rotation of the bottom support platform rotates the container relative to the lid for loosening the lid to facilitate removal. The apparatus includes a drive motor which is energized as the top friction pad is biased downwardly and into engagement with the lid of the container. Alternatively, the drive motor can rotate the support platform in an opposite direction to seal jar lids for use during canning. The apparatus also includes a can opener on the underside of the apparatus housing which is operated by the same drive motor. When used as a can opener, the upper friction pad of the apparatus can be pivoted to a folded position after which the entire apparatus can be turned over to be supported on a side of the housing providing convenient access to the can opener drive gear.
