ABSTRACT:
A pouring spout, for use on a container, of the type having a tubular spout member with a pouring passage therethrough and a venting passage extending within the pouring passage is improved by forming the venting passage in a venting tube that is attached to the spout member and has an inlet end portion that extends outwardly from the pouring passage at its inlet end in a manner that is curved upwardly so that a free end thereof would be within an air space formed in the container during a pouring operation. According to a first embodiment, the venting tube is a separate element from the pouring spout that is clipped within its pouring passage. According to another embodiment, the venting passage is unitarily formed with the spout member.
