ABSTRACT:
The invention relates to a carton, particularly constructed so as to be mass produced by an automatic carton manufacturing machine. The carton comprises four side portions, each of which contain, on each end of the side portions, a flap portion. The flap portions are constructed to form the two ends of the cartons. Each of the flap portions has a unique shape, such that when they are sequentially folded on top of each other, the flap members form a locking arrangement. This enables one side portion of the carton to be opened and closed a fixed distance, said movable side portion being interlocked with another side portion of the carton.
