摘要： A device for loosening and tightening the lids on jars or containers. The device has a handle, and a strap and brace attached to the handle. The strap is placed through the brace and formed into a loop so that it may be slipped over the lid. When a rotational force is applied to the handle, the brace pulls against the strap so as to apply a rotational force to the lid which is greater than the force applied to the handle. A spike extends from the top of the device which is placed through a hole in the strap to secure the strap to the handle. The strap has a series of holes to accommodate a large variation in sizes of lids. For loosening the lid, a counter-clockwise force, relative to the center of the lid when viewed from above, is applied to the handle. For tightening the lid, the handle is reversed and a clockwise force is applied to the handle. For infirm users who have arthritic hands and cannot grasp lids or containers, two devices may be used, with one strap placed around the lid and the other around the jar or container. The lids can be loosened or tightened by pushing against the handles rather than grasping them.
摘要翻译：用于松开和拧紧瓶子或容器上的盖子的装置。该装置具有手柄，以及附着在手柄上的带子和支架。带子通过支架放置并形成一个环，使其可以滑过盖子。当旋转力施加到手柄时，支架拉动带子，以向盖子施加大于施加到手柄的力的旋转力。尖头从设备的顶部延伸，该顶部通过带中的孔放置，以将带固定到手柄上。表带有一系列孔，以适应盖子尺寸的大变化。为了松开盖，当从上方观察时，相对于盖的中心的逆时针力被施加到手柄。为了收紧盖子，把手被反转，并且向手柄施加顺时针力。对于具有关节炎手并且不能抓住盖子或容器的体弱者，可以使用两个装置，一个带放置在盖子周围，另一个围绕瓶子或容器放置。可以通过推动手柄而不是抓住盖子来松开或拧紧盖子。
