ABSTRACT:
A carton blank formed from a continuous sheet of material and capable of being easily folded into a self-supporting carton structure. A unique cover locking arrangement is provided whereby both lids forming the cover are independently locked against accidental opening without the aid of external fasteners and further provide superior protection for the contents of the carton against dust and moisture. The absence of external fasteners also make the carton more economical to manufacture and aesthetically pleasing to look at. The carton is also equipped with improved hand holes to facilitate balancing and carrying of the box when loaded.
