Abstract
A folded carton includes base and top portions. The base portion has a bottom, sides and web corners to the base portion can hold liquid. The sides and web corners are temporarily maintained in the folded condition while the carton is being filled with a product by using tabs and notches in the sides and web corners. The top portion includes a top, side flaps and a front flap. Portions of the carton material are coated with a waterproof, heat sealable coating. After filling, the flaps are sealed to the sides using heat. A top flap, including a lifting tab, is creased by partially scoring outer and inner surfaces of the top and the front flap to create a frangible tear path allowing the top flap to be lifted up away from the top portion, thus exposing the contents. A portion of the front side opposite the lifting tap is recessed to aid lifting of the tab.
