Novel pouring spouts for a container are provided herein. The spout includ es depending wings extending down from the bottom edge of the spout. The wings terminate in a point for piercing a container. The depending wings define an angle which is greater than ninety degrees with respect to the chute. Stop means a re formed along the upper edges of the side walls of the spout, which permit th e spout to open by pivoting about an arc of ninety degrees. The spout is inserted in to a container with an apparatus which includes a ram which drives the spout against a ramp to rock the depending wings upward with respect to the bottom edge of t he spout. Thereafter, the ram drives the points into the container and the uppe r edges of the side walls contact the container and cam the back of the spout to a horizontal position. This allows the spout with the depending wings to be inserted into a container through slits that are sized properly to receive and hold the spou t in the container. |
