ABSTRACT:
A reusable container closure which telescopes over the open top or bottom of the container is formed by utilizing a one-piece paperboard blank which is cut, scored, and folded to present a central panel, and at least three side panels depending from the central panel. A first side panel has a corner flap. A second side panel has a notch. The first side panel and the second side panel meet to form a corner. The corner flap is folded about the corner to lie against the second side panel. The corner flap also has a friction stop folded to engage the notch, which extends through the notch. When the container closure is telescoped over the container, the container urges the friction stops towards the second side panel so that the container closure embraces the top of the container. When the container closure is later removed from the container, the friction stop is simply disengaged from the notch and the container closure may be flattened and returned for re-use.
