Abstract
A carton with an opening through which the contents can be poured. An opening in an end panel is normally covered by a closure flap connected to the top panel. The flap is maintained in closed position by another flap which includes a tear strip. Removal of the tear strip permits access to the closure flap, enabling it to be opened for pouring. A slot in the end panel receives the closure flap when the closure flap is reclosed.
