ABSTRACT:
An automatic lock bottom carton with a pyramid closure is disclosed having two tabs extending from two panels that lock into corresponding openings on tabs of oppositely presented panels. The double lock prevents the collapsing of the pyramidal shape so that it can support a product in its intended form. The carton can be of single cell or multiple cell structure with one of the pyramid sides derived from the center divider.
