Abstract
An isosceles triangular plate with depending flanges on its two equal sides is provided, adaptable for mounting under kitchen or galley shelves or cabinets for the purpose of loosening and tightening screw-type lids or caps of jars, bottles, and the like. A resilient rubber gripping bar is fixed to said triangular plate and bisects the angle between said flanges. Screw type closures are loosened or tightened by their insertion on the appropriate side of said bar and rotated clockwise or counterclockwise respectively. The camming action of the flange serves to wedge the lid more tightly against the rubber bar, thus increasing its gripping force.
Claims7
A device for tightening or loosening a screw top of a threaded vessel comprising a unitary triangular wedge shape having a planar substrate wherein all perimeter sides of said substrate of said triangle intersect to form an isosceles or equilateral triangle having a base line, said triangular wedge shape having a first and second side raised above said substrate and having a relatively smooth interior edge, both said first and second side at one terminus each interconnecting to form an apex of said triangular shape and the other terminus of each intersecting the base line of said triangular perimeter, said triangular wedge shape possessing a raised, relatively smooth sided rubberish flexible gripping means disposed in a plane parallel to the plane in which said apex is situated to form two right triangles within said isosceles or equilateral triangle wherein;
- (a) a first right triangle is formed by one-half of the planar substrate base line, the relatively smooth sided rubberish flexible gripping means and said first smooth side;
- said first right triangle being receptive to said screw top of said threaded vessel wherein said screw top is loosened by rotating said vessel in an opening direction of rotation;
- and
- (b) a second right triangle is formed by one-half of the planar base line, which is distinct from the one-half of planar base line of said first right triangle, the relatively smooth sided rubberish flexible gripping means and said second smooth side;
- said second right triangle being respective to said screw top which is tightened by rotating said vessel in a closing direction of rotation.
