Abstract
A device for siphoning various fluids including gasoline from a relatively closed container. The device includes a siphon tube about which is positioned an expandable bulb which is pressurized, usually with oral pressure, to expand and form a seal with the containers opening. A restricted outlet for such pressure is provided beneath the sealing surface of the bulb to allow this pressure to also pressurize the container into which the siphon is inserted, thereby forcing fluid up the siphon tube until siphon action starts. Thereafter, the pressure line provides a vent for the fluid container should the seal remain intact.
Claims10
A device for siphoning fluids such as gasoline outwardly via the neck of a fluid container, said device including:
- a first tube for flow of the fluid out of the container, said first tube having an outlet end and having an inlet end for immersion in the fluid;
- a second tube having an outlet end and having an inlet end for the application of pressure thereto;
- and
- a hollow plug through which said first tube extends, said plug having a hollow interior, an expandable side wall positioned for sealing engagement with the neck of the container, means for connecting said second tube outlet end so that pressure in said second tube is applied within said hollow interior of said plug to expand said side wall into sealing engagement with the neck of the container, and a restrictive outlet positioned between said first tube inlet and the sealing engagement of said side wall and container neck to apply reduced pressure within the container and thereby to force the fluid from the inlet end to the outlet end of the first tube.
