ABSTRACT:
A wide three row 18 cell egg carton adapted to be stacked for use in standard 12 cell egg filling machinery has a tray section with three longitudinal rows of side-by-side egg cells, an upwardly and outwardly inclined stiff latch flap integrally hinged to the front top edge of the tray section, a dished cover section integrally hinged to the top rear edge of the tray section and a perpipheral wall on the cover bottoming on the top of the tray section adapted to receiver the latch flap there behind and having receptacles to receive the latches of the flap. Pairs of the cartons are molded in side-by-side relation on a standard width thermoforming machine from thermoplastic sheet material and sufficient molding area for the wider three roll 18 cell cartons and the flaps is provided by forming the flaps of the pairs in juxtaposed side-by-side relation inclined toward each other away from the sheet line as the trays and covers of the carton are formed. The inclination of the flaps away from the sheet line provides additional space to mold the flaps without widening the forming area.
