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.

Gable top carton

A fin-sealed, flat-topped, liquid-packaging carton with substantially triangular flaps of its tope end closure turned down and tacked to adjacent body panels has the horizontal part of its fin heat and pressure adhered to the top wall along approximately only that half of its length further from the triangular flap which will provide a pouring spout so that turning upwards of the spout end of the fin from its position flat against the top wall tends to pull upwards the central part of the top wall. Two score lines extending divergingly from the spout end of the top wall at respective opposite sides of the fin to respective corners of the opposite end of the top wall are thereby broken outwards rather than inwards.
