ABSTRACT:
A pouring and drinking spout adapted for sealed engagement with the mouth of a variety of containers of the easy-opening, pull-tab type. The spout is preferably molded to form a hollow, barrel-shaped spout portion which is enlarged at one end to form a ring-shaped flange or lip, defining a circular bearing surface to which a resilient washer is attached. A flared camming member aligned with the axis of the spout engages with the inner edges of the mouth of the container as the spout is manually rotated, clamping the washer between the container and the circular bearing surface of the spout, forming a seal. A stop lug, spaced radially outward from the axis of the barrel, engages with the inner edge of the container mouth to prevent further rotation when the spout is in its locked position. A deformable cap is pressed over the mouth of the spout to re-seal the container.
