Abstract: An apparatus for dispensing measured quantities of viscous material from a pressurized supply source including a measuring cylinder having a spring loaded piston therein and a rotary valve for alternately communicating the measuring cylinder with the supply source and with a discharge outlet. The rotary valve member has axially spaced O-ring seals to inhibit leakage from the ends of the valve member and an inlet seal for sealing against leakage from the pressurized inlet passage in a direction circumferentially of the rotary valve member.

Abstract: A substantially spherical hollow body is filled with a fire extinguishing chemical under greater than atmospheric pressure. The top of the body is provided with a normally closed exhaust valve biased open by a handle. The handle is also used to throw the extinguisher into a fire.

Abstract: Measuring receptacle means comprising a plurality of cup members, each having an open top and bottom, with a removable bottom closure means in common with the cup members. Each cup member is of a different volume than the other cup members. Removable bottom plate means slidably closes the bottoms of the cup members such that the individual cup members are fillable with a measured material from the top when the bottom plate is in closure relation, and emptied from the bottom when the bottom plate is slidably removed.

Abstract: A device for the accurate measuring and for holding a discharge of liquid quantities is described as well as apparatus for charging liquid into the device from bulk storage. The measuring and dispensing device includes a liquid compartment, a dispensing nozzle, a carrying handle and a nozzle operating means adjacent the carrying handle. The compartment includes a vent which is open and closed by the nozzle operating means with a float included in the vent to shut the vent when filling the device and when liquid in the device reaches a chosen level. A coupling nozzle is engageable with the first-mentioned nozzle for charging liquid into the device and includes a stem and a sliding sleeve which cooperate with the first nozzle to allow liquid flow from the coupling nozzle through the first nozzle and into the compartment for charging the compartment.

Abstract: A safety-adapted pivoted closure device for vessels containing volatile or flammable liquids is disclosed. The disclosed pivoted closure device has a flash arrester and safety vent, with the resulting device being positionable on a vessel, such as a portable receptacle containing gasoline. A spring biases a closure cap on the device toward a closed position, and the spring bias is overcome if a predetermined pressure build-up occurs within the vessel to thus allow the pressure to be relieved. Should this occur, gas and/or fumes are expelled from the vessel, but only through the flash arrester. A handle and linkage assembly are provided for manually moving the cap from a closed position to open the receptacle by overcoming the spring bias thereon with the handle and linkage assembly being designed so as not to prevent release of a pressure build-up within the vessel while the cap is in a closed position.

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.
