<p>A fuel container status indicator tag for signaling the status of the contents of a fuel container, for example whether gasoline has been mixed with two-stroke oil, or is not yet mixed. The tag includes a casing (1), an actuator (14) mounted for rotation within the casing, and a window (4) for showing the status. The actuator includes a disc-shaped plate (14) and a radial tab (20) that protrudes through a slot at one end of the casing and is movable between the ends of the slot to reveal different status signs, such as red and green, through the window. A double-locking system (5, 7) prevents accidental switching. In one embodiment, an integral calculator (2, 3, 10) is provided for determining the volumes of gasoline and oil needed for specified mix ratios.</p> |
