Abstract
A fuel supply (1) including a cover (2) having an opening (8) for access to the fuel. The cover (2) includes a shutter (12) or similar element for closing off the opening (8) to increase the operational resistance to the insertion and/or removal of the fuel supply (1). In one embodiment, the cover (1) includes a support (6) with a rotatable cap (4), where the rotation of the cap causes the shutter (12) to open. In another embodiment, the cover includes a base and a slidable cap, where the slidable cap is the shutter. The shutter (12) may be manually actuated, mechanically actuated or electrically actuated. The cover (2) may be biased to the open position or to the closed position.
