Abstract: An applicator (10a) affixes fitments (12) to paperboard cartons (20), each fitment (12) comprising a screw cap on a pour spout. An ultrasonic horn (18) reciprocates between a retracted position for receiving a fitment (12) and an advanced position for depositing the fitment (12) on an outer surface of a carton (20). A duct (26) extends and provides fluid communication between an air handler and a fitment-holding recess (30) formed in the horn (18). The air handler is actuable to evacuate the duct (26) to retain a fitment (12) in the recess (30) by suction while transporting the fitment (12) to be affixed to the container wall. The air handler also supplies pressurized gas to the duct (26) to blow the fitment (12) from the horn (18) before the horn returns to the retracted position.

Abstract: A testing method comprising introducing into a pressure chamber (2) a batch of gable-top, plastics-coated paperboard cartons (10) containing a liquid, closing the chamber (2), supplying air under pressure to the interior of the chamber 2 exteriorly of the cartons (10) to a pressure level sufficient to cause the air to penetrate potential leakage paths between the outside of at least one of the cartons and the interior of the latter carton(s), whereby the air penetrates into the interior of the latter carton(s), and, after a period of time, reducing the pressure level, whereupon the air which has penetrated into the interior of the latter carton(s) causes outward bulging of the side walls of the latter carton(s).
