ABSTRACT:
An end closure for a container comprising an end cap and a cover rotatable with respect to the end cap. The end cap has a raised portion connected to the main part of the end cap by a thinned, severable wall. The raised portion fits within an opening in the end cap, which opening is defined at least in part by a knife edge. Upon rotation of the cover relative to the end cap, the knife edge will cut through the severable wall and sever the raised portion from the end cap. A pour opening is defined in the end cap when the raised portion is severed. When the opening in the cover is aligned with the pour opening in the end cap, the contents of the container may be dispensed. When the opening in the cover is out of registry with the pour opening in the end cap, no contents may be discharged. Complementary inter-engaging flanges on the end cap and cover retain the parts in assembled relationship. In one embodiment of the invention, the opening in the cover includes a flat wall adapted to abut the raised portion and preclude rotation of the cover in one direction until the raised portion is removed. Another embodiment of the invention includes cooperating means on the cover and on the end cap to preclude retrograde motion or reverse motion of the cover with respect to the end cap once cutting of the severable wall begins.
