ABSTRACT:
A hexagonal carton including four upstanding sidewall panels and two diagonally opposed corner panels. The entire carton is formed from a single blank. The corner panels include minor flaps hingedly foldably connected thereto which interact with minor flaps foldably hingedly connected to the adjoining sidewall panels to form a rigid interlocked cover panel which withstands lateral pressures exerted on the sidewall panels of the carton. Major flaps are foldably hingedly connected to two of the sidewall panels to form a cover panel to cover the interlocking minor flaps.
