ABSTRACT:
A lid wrench for removing lids from jars and other containers, which lid wrench is characterized in a first preferred embodiment by a smooth, elongated lug-receiving member slidably receiving a single sliding lug provided with inwardly-facing lug teeth. In a second preferred embodiment, the lug-receiving member is provided with spaced slots or teeth for selectively receiving an engaging shoulder or shoulders of the sliding lug. A fixed handle is attached to an offset end of the lug-receiving member opposite the sliding lug and an opening and/or ring maybe provided in the opposite end of the lug-receiving member for suspending the lid wrench from a nail or other support. A spring-biased, curved jaw, provided with multiple, spaced jaw teeth which face the lug teeth on the sliding lug, is pivotally secured to the offset end of the lug-receiving member spaced from the fixed handle, and receives a jaw handle. Gripping and squeezing of the fixed handle and the jaw handle pivots the curved jaw against the bias of the spring in a camming action against a jar lid or cap disposed between the jaw teeth and the lug teeth located on the sliding lug, to lock the lug on the lug-receiving member and loosen the lid or cap responsive to twisting of the lid wrench.
