Abstract
A pouring device for pouring lubricating oil into the oil filler neck of a conventional engine. The pouring device is adapted to prevent unwanted spilling of oil onto the exterior surface of the engine block during the pouring operation. The pouring device has a cylindrical connecting neck portion which is adapted to be threadaly mounted over the discharge aperture of a conventional lubricating oil container. The connecting neck portion extends integrally into a spout. The spout has an inlet surface. A sealing membrane is hingely connected to the connecting neck portion, adjacent the inlet surface. The sealing membrane is adapted to pivot between a closed position wherein it prevents the lubricating oil from flowing through the inlet aperture and an open position wherein the sealing membrane allows the lubrificating oil to flow through the inlet aperture. The sealing membrane is adapted to be releasably locked in its close position by a locking lip which abuts against its peripheral edge. A biasing strip extends integrally from the sealing membrane. The biasing strip is adapted to create an initial biasing force which biases the sealing membrane against the locking lip. A trigger m…
