Abstract: A safety valve assembly for use with a portable container, such as for dispensing fuel to a vehicular gas tank, where the valve assembly features a pair of fluid sealing members to be manually activated to effect dispensing of the fluid from the container. A first of said sealing members includes a magnetizable float member that further functions to automatically shut-off the fluid dispensing procedure before the receiving receptacle overflows, thus avoiding a problem with unwanted spillage. The second sealing member is activated by applying pressure to the container against the receiving receptacle, whereby premature spillage is further avoided during transporation of the fluid filled container. Finally, a rotatable lock mechanism, in the form of a camming system, is provided.

Abstract: An automatic shut-off valve assembly having particular utility in a portable container of the type for dispensing fluid, such as fuel into a vehicle gas tank, where speed, safety and convenience are prime requirements. The valve assembly includes a spring biasing mechanism to effect opening and closing of the valve assembly. The assembly further includes a generally circular, hollow housing containing a slidably movable insert, which receives the spring, where the spring effects an automatic closing of the assembly, but yields upon the application of axial pressure to open the assembly.

Abstract: A portable fluid dispensing system, such as for the transfer of fuel to a vehicle fuel tank, that is convenient and safe. The system hereof includes a closed fluid containing chamber, having access means for fitting the chamber, air relief means, and a quantity regulating dispensing mechanism. The quantity regulating dispensing mechanism includes a pair of concentric tubular members, rotatable relative to one another, where such members feature a series of apertures or ports that may be aligned, through rotation of one of the members, to control the quantity of fluid to be dispensed at any given time, such as in increments of gallons.
