Abstract: A screw cap twisting tool uses two primary members—a stationary member with gripping surface(s) and a high-mechanical-advantage-for-gripping pivoting member with gripping surface(s)—to easily and effectively grip and twist a screw cap. The screw cap twisting tool is easily operated by pushing the screw cap against the pivoting member. A screw cap twisting tool also uses a method for holding the pivoting member in its most open position before screw cap insertion. This method for holding the pivoting member in its most open position can be accomplished in numerous ways by using a force opposing feature, member, or mechanism that allows movement and/or deformation when force is applied and restores position and/or shape when force is removed. Examples include, but are not limited to: built-in elastic metal or plastic material, separate metal or plastic spring, separate elastic O-ring or rubber band, gravity, or magnetism.

Abstract: The present invention provides a jar opener which is designed for easy handling by people with arthritis. The jar opener providing a larger than normal handle with one end being flat and non functional while the opposite end is indented in a concave dish design, with a gripping teeth thereon, so as to accommodate and mate with the ribbed edge of any cap on ajar. A gripping strap loosely wraps around the cap of ajar while the opposite end of the strap aligns and tightens onto the opposite side of the handle by a releasable securing means, such as VELCRO. The user then grasps the handle of the present invention in one hand and uses their opposite hand to stabilize the jar. The user simple applies grasping pressure on the handle of the present invention and pushes in a counter clockwise direction thereby loosening the cap while rotating the cap of the jar to the open position. The strap is sufficiently long enough to be wrapped around any size circumference of a cap.

Abstract: A device for loosening threaded lids from correspondingly threaded containers, comprising a body carrying first and second flexible belts (20, 26) forming first and second loops which engage around the lid and the container respectively, the belts (20, 26) being arranged to be relatively displaceable such that the first and second loops grip the lid and the container respectively, the belts further being arranged to be displaceable by an actuating means such that the first and second loops apply oppositely directed torques to the lid and container respectively whereby the lid is rotated on the container in a loosening direction. Both the lid and the container are thus gripped by the device rather than by hand. The loosening of the lid may be achieved by the rotation of only one of the loops relative to the body, the other loop serving to prevent rotation of the lid or the container relative to the body. Alternatively, both of the loops may rotate relative to the body in opposite directions.
