  • Patent number: 6494708
    Abstract: A method and apparatus is taught for a safety device for a lighted device in a container. The safety device comprises a closing device, an attachment device, and a holding device. The safety device further comprises a coupler configured to operatively couple the closing device, the attachment device, and the holding device so that the closing device moves between a first and second position. There is also an extension coupled to and extending from a surface of the closing device, a securing system coupled to the attachment device, and a timing device coupled to and protruding from a surface of the holding device. Finally, the timing device is operatively configured to interact with the extension when the closing device is in the second position to actuate movement of the closing device into the first position so that the lighted device in the container is extinguished in a predetermined amount of time.
