PURPOSE: Provided is an injection molded fitment with reduced plastic in the canoe base, to retain the shape and length of the canoe, but to reduce the amount of plastic in transition areas and in the wall thickness of the base. CONSTITUTION: The fitment(10) has walls(13,14,16) with a spout aperture(12) therebetween. Wall thickness reduced to 0.5mm results in a reduced amount of plastic in the fitment. An alternative embodiment uses radially extending meltable fins. During installation in a sealing apparatus, a heated mandrel engages the inner diameter of the spout aperture(12) thereby pre-heating and physically supporting the fitment(10) during the installation process. The heated mandrel typically engages the fitment(10) at least one cycle prior to its installation. The fitment(10) may be canoe-shaped. |
