Method of constructing flexible containers with tubular fitments

摘要

A method is disclosed for constructing a flexible container (10) with a tubular fitment (13). The method includes placing the fitment upon a mandrel (22), positioning the mandrel supported fitment between the unsealed sides (25, 26) of the container, sealing the top edge (28) of the sides about a base portion (18) of the fitment and fully withdrawing the mandrel from the fitment and from between the sides so that the side edges (29) and top edge of the sides may be sealed to form a completed container.
