Abstract: A snap-on lid for covering opened beverage cans securely enough to contain effervescent gases effectively during storage of the beverages in such a container, including a collar defining a groove which is downwardly open to receive an upwardly-directed edge of the container. A convex dome is located within the area circumscribed by the collar, and a flexible annular portion surrounds the dome portion of the lid and interconnects it with the collar. A skirt depends from the outer side of the collar portion and fits sealingly against the outer surfaces of the container. An upper margin of the skirt has an inner diameter smaller than that of the outer wall of the collar, presenting an inwardly-directed lip along the open edge of the groove defined by the collar, to engage the bottom of a bead defined at the top of the container and thus aid in retaining the lid in place on the container.

Abstract: A tethering system for restraining the movement of portable electrical devices such as games, toys, radios and tape players used by vehicle passengers, while supplying electrical current for operating such electrical devices, is employed in combination with a power switch which permits electrical current to be supplied to an electrical device only when the passenger seat belt assembly is coupled. The system includes a tethering member which is connected to the vehicle independently of the seat belt buckle assembly for detachably connecting to the electrical device. The tethering member also has electrical conductors for receiving electrical current from the power switch and conducting it to an electrical outlet on the tethering member.

Abstract: An automotive passenger seat belt contains a selectively energizable and de-energizable DC electrical outlet into which the passenger may plug various electrical entertainment devices, such as radios, stereos, electronic games and the like to receive operating power. Energization of the electrical outlet is controlled by a switch which is placed in its energizing position only in response to coupling of the two seat belt portions together, indicating that the seat belt is being used. The electrical outlet is automatically de-energized in response to decoupling of the seat belt portions. The electrical outlet has an adjustment to provide different DC voltages for different types of electrical devices which may be connected thereto. An optional remote indicator can also be connected to the switch to indicate whether or not the seat belt portions are coupled.
