The present invention pertains generally to portable
metal storage containers for gasoline, kerosene, oil and
other volatile ‘liquids. More speci?cally, the invention
is directed to a ?exible rubber pour spout for mounting
in a said container closure cap.
The object of the invention is to provide a closure cap
and a ?exible rubber pour spout for portable storage
containers of the character described.
