ABSTRACT:
An easy opening end closure is arranged and adapted to accommodate pouring of products with varying viscosities. The end panel includes a number of portions disposed to obstruct displacement of the tab and thereby limit opening of the closure to a predetermined segment thereof. The portions are deflectable to a non-obstructing position by application of sufficient force thereagainst, enabling the user to determine the size of the pour opening by controlling the number of segments opened.
