Patent number: 10905279Abstract: A lid holder has a base portion and a pair of spaced apart arms having a proximal end connected to the base portion and a free distal end extending away from the base portion. The lid holder further has a U-shaped lug at the free distal end of each arm, the lug having a first end and a second end directed toward the base portion, and a leg connected to the second end of each U-shaped lug, the leg protruding in an outward direction away from the arms. The arms are deflectable from a first position to a second position with application of a deflecting force such that at least a portion of the arms is insertable between vertically extending posts of a lid handle. After a deflecting force is removed, the arms revert back toward the first position, thereby engaging the legs with the vertically extending posts of the lid handle.Type: GrantFiled: October 17, 2018Date of Patent: February 2, 2021Assignee: All-Clad Metalcrafters, L.L.C.Inventors: William A.
