ABSTRACT:
Carton for eggs and the like including a tray section having rows of generally conical cavities with ovate sidewalls and corner bolsters hinged to opposite sides of the carton and connected together by side panels hinged along the same side lines as the bolsters and extending partially upwardly of the articles in the cavities when the bolsters are hinged upwardly to cover the corner articles in the carton. Stops spaced inwardly of the hinge lines extend upwardly of opposite edges of the carton and afford support for the side panels and limit inward movement thereof as the bolsters are moved to protect the articles in the corners of the carton.
When the tray is loaded with eggs, it is placed in a plastic bag which is heat shrunk to the carton to rigidify the carton. The heat of shrinking seals the open end of the bag as the open end is drawn together by the heat shrinking operation. The corner bolsters enable ready stacking of the cartons one on top of the other with the eggs in the top carton spaced above the eggs in the lower carton.
