Giebelbehälter mit einem Ausgiesser.

摘要

A construct ion for attaching a flanged pour spout to a gable top type paperboard carton blank for packaging potable liquids. The blank (10) is provided with a barrier (24, 26) layer on its inner and outer forming surfaces, and a pour spout (32) extending out from one gable forming panel. An opening is die cut (18) in this panel, and the barrier layers applied. These layers span the opening. Thereafter, a pouring aperture is cut in the barrier layers which span the opening. An annular seal between the two barrier layers is formed by pressing the layers together while applying ultrasonic vibrations to them. The flange of the pour spout is adhered to the outer barrier layer, also by pressing and applying ultrasonic vibrations. By this construction, the edges of the opening in the paperboard are sealed and cannot contaminate the liquid within a carton formed from the blank.
