Abstract
Abstract A demountable pouring spout is disclosed for liquid containers which are sealed by a closure inserted into a filling orifice. In one embodiment the spout is a conduit with a piercing member at one end and an orifice adjacent the piercing member. During shipment and storage the spout is connected to the sealed container by the orifice engaging a post formed on the closure. During use the spout conduit frictionally engages a closure conduit, and the piercing device ruptures a frangible sealing membrane in the closure so that the orifices can be inserted into the container and the contents discharged through the orifices and the conduit. The container is resealed by positioning the spout orifices within the closure conduit. In a preferred embodiment the spout has two conduits joined at right angles to each other with the second conduit having a respiration valve adjacent the first conduit.
