ABSTRACT:
A fitment application apparatus, for applying plastic spout fitments to filled and sealed cartons, is integrated in line with a conventional form/fill/seal production line. The fitment application apparatus includes a conveyor for intermittently advancing each one in a series of formed, filled and sealed cartons in turn to a fitment application station. A hopper and associated gravity-feed track supply a series of fitments to a fitment applicator anvil. Each fitment has a flange portion, the bottom surface of which is coated with hot melt adhesive as the fitment slides past a hot melt adhesive applicator roll. A fitment retaining mechanism receives and positions each fitment such that the flange bottom surface coated with hot melt adhesive faces an external side of the wall of the filled carton. The fitment applicator anvil intermittently carries fitments from the fitment retaining mechanism into abutting relationship with the filled carton in registration with the spout hole, thereby pressing the flange bottom surface coated with hot melt adhesive against the extrusion layer on the external side of the carton wall, whereby the fitment is applied to the filled and sealed carton.
