ABSTRACT:
Disclosed is a multicell carton having a base element with side panels, and gang lift elements formed as an extension from the side panels. More specifically, a breakaway strut panel is integrally formed with the initial panel, and thereafter folded over and glued, and severed from the initial panel in order to define the divider strut between the two strut gang lift elements. A divider strut glue flap extends from one of the gang lift elements and is secured to the single thickness breakaway strut, thereby reducing the board construction from approximately 235 square inches for the carton as shown in U.S. Pat. No. 4,274,579 to 225 square inches or a 10 square inch saving amounting to a 4.3% reduction in the use of board. The method of the invention contemplates first glueing the breakaway strut portion to the graphic panel and then severing the same by sawing or otherwise cutting to form an independent element on the underneath portion of the graphic panel. Thereafter the strut fold score results in a 180.degree. folding of the divider strut and its breakaway strut assembly to form the first gang element of the carton. Subsequently, the glue strip is adhered to the divider strut, the divider strut glue panel folded 180.degree., and the strut gang lift section folded along the final fold score to complete the glueing of the divider strut glue flap to the divider strut and complete the carton construction.
