ABSTRACT:
A leak resistant carton is formed from a cardboard blank by folding the blank to an open-ended carton. The carton is positioned on a core support member and a flexible sheet of closure material is placed over one of the open ends of the carton. A platen above the open end of the carton is actuated to fold and seal the edges of the sheet material over the sides of the carton to close the carton. The carton is then inverted on a conveyer and passed through a filling station, glue station and flap closure station. The carton is first filled and the side flaps are folded inwardly. A glue head assembly traverses the carton diagonally to apply a transverse bead of glue on the carton flaps. The remaining carton flaps are then folded inwardly to close the carton.
