  • Patent number: 4069946
    Abstract: An improved consumer safety container for the storage and dispensing of flammable liquids, formed as a hollow chamber having a continuously closed inner surface, the chamber having formed therein a number of tubular extensions with openings for filling, pouring and venting the container. A spring-loaded compression closure device is mounted in these openings to provide an effective seal of the container. Closure attachment means position and protect the spring loaded compression closure means within the container. Flammable liquid may be filled into or dispensed from the container by release insertion means which disengage the compression closure device.

  • Patent number: 3964728
    Abstract: A self closing safety gate valve controls the flow of heavy, viscous fluids such as machine oil, rubber cement, lacquer, or the like. The valve housing contains a rotor with a spring biased thrust exerted laterally against the rotor, to hold it--in normal position--against the housing wall with a metal-to-metal seal at the output orifice. When the rotor turns, a pair of large output orifice openings, in the housing and rotor, are aligned--in off-normal position--in order to enable the out flow of fluid. A spring biased handle automatically returns the rotor from the off-normal to the normal position, where the thrust again presses the rotor body against the large output orifice opening in the housing.

  • Patent number: 3953723
    Abstract: A plastic carbide lamp includes upper and lower containers or housings with a water control needle valve therebetween. As the needle valve opens, water drips from the upper container upon calcium carbide in the lower container, to generate acetylene gas. The acetylene gas rises into a dome shaped collection chamber having a burner tip therein, at which the acetylene gas burns.

  • Patent number: 3934328
    Abstract: A completely enclosed plastic can or container has a neck-like opening closed by a spring biased cap. The cap is controlled by a handle linkage connected to a vertical fin formed on the can by an enlargement of the flash line between two plastic mold parts, which are joined together to mold the container, preferably by a blow molding process. Springs automatically urge the cap and handle to a closed position when the container is sitting at rest. The cap opens as the can is tipped while the handle is being held. A clip-on pouring spout is snapped onto the neck to guide the fluid flowing from the can.
