Abstract: A display carton formed from a single blank of paperboard or the like having an outer carton structure and an inner product compartment. The outer carton structure has spaced outer front and rear walls separated from each other by a pair of outer carton side walls and said inner compartment comprises a pair of inner side wall panels and a rear panel. The inner compartment is secured to said outer carbon structure so that rear inner compartment panel is not secured to said rear outer carton wall and the inner compartment side panels are not secured to said outer carton side walls so that when the carton is squared and erected said inner compartment may be erected independently of the squaring of said outer carton by snapping said inner compartment into its erected position. A self-centering beam is also provided to insure the automatic centering of the inner compartment.
