ABSTRACT:
A receptacle includes pairs of opposed side panels which are connected by connector flaps. The connector flaps have two relatively movable flap portions and the flap portions cooperate with tabs formed in the side panels to lock the receptacle into assembled condition and prevent up and down movement of the connector flaps relative to the rest of the receptacle structure.
