ABSTRACT:
The invention comprises a closure for carton board containers which is an extension of the top flap. A dispensing opening is partially die cut through an end wall of the container, thereby forming an opening with a removable plug. The plug is glued to the closure flap so that it comes away with and is a functional part of the closure flap. A locking tab depends from a lower edge of the closure flap and is spot glued to the end wall when the container is initially filled. The closure is initially opened by pulling on the tab and breaking the spot seal. A pair of score lines extend across the closure flap on the one hand and adjacent to the tab on the other to facilitate closing and locking. In an alternate embodiment, an additional top mirror end flap is provided to enhance carton sealing and product containment.
