ABSTRACT:
A brick type container, particularly adapted for aseptic packaging of product such as potable liquids, is formed having optimum dimensions and location of a pour spout fitment thereon. The dimensions of the pour spout components are chosen for optimum performance. The top of the container carries a dispensing opening covered by a severable or frangible extrusion coating or other type of membrane. The fitment is applied to the container by applying it while the container is encased in a pocket on a conveyor, the pocket sides being rigid. The fitment includes a hollow cutter having cutting teeth on its lower periphery, the cutter also functioning as part of a pour spout. The toothed end of the cutter severs the membrane to permit dispensing of product from the carton. To prevent the severed extrusion or membrane which originally covers the dispensing opening from passing out of the carton upon dispensing of product, a flow filter is provided in the form of bars at one end of the entrance lumen of the cutter element. Typically, these bars are integrally molded with the cutter. The bars are located above the lower portions of the cutting teeth, in a plane containing the teeth roots or bases, to thereby preclude entry of a severed disc of membrane from entering the lumen of the pour spout or the cutter.
