Abstract
A closure clamp is disclosed for use with food bags, such as potato chip bags. It comprises a pair of clamp members in hinged construction and a torsion spring for holding the members together and applying a clamping force. Each clamp member includes a jaw, a handle and a fulcrum member and the spring includes a torsion rod disposed between the fulcrum member and the free ends of the handles. The jaws are bar-like structures and are long enough to span a large part of the width of a food bag.
