Abstract
An apparatus and method for securing a pour spout fitment to a panel of a filled and sealed thermoplastic-coated carton, wherein a machineis mounted over a conveyorconveying a line of cartons. Within the machinea selected panel surface of each filled and sealed carton is heated to a predetermined temperature; next, at least an annular surface of a flange of the fitment is heated to a predetermined temperature. When the heated surface of the fitment is applied to the heated surface of the carton, the heat energy is transferred to the latter surface to an extent capable of activating the thermoplastic coating thereon. Upon pressing and cooling, the fitment and the carton surface are bonded together, without the need for a back-up or support mechanism, such as a mandrel or anvil. Alternatively, the fitment may be secured to the carton by way of a jetted-on, circular bead of hot melt adhesive.
