Abstract
A closure device allows a welding rod container to be reclosed in an air and moisture tight manner after being opened. The device includes a frame member having an opening therein, and flanges extending downwardly from the frame member outer edges for secure attachment to the container. The opening is of sufficient size to allow a human hand to retrieve a welding rod from the open welding rod container while also helping to prevent contact of the hand with the dangerous sharp edges of the open container. A latchable lid member capable of fitting within the frame member and covering the opening therein is hingedly connected to the frame member such as by an internal or live hinge. The lid member is provided with a flanged bead extending along its outer edges capable of mating with a groove extending along the inner walls of the frame member. When the device is closed, the groove and bead mate thereby helping to form an airtight seal between the lid and frame member for protection of the welding rods from the atmosphere.
