  • Patent number: 7017796
    Abstract: A paper packaging container is obtained by tube forming with a longitudinal seal of web-shaped packaging material. The package is filled with liquid food, and a transverse seal of the tube packaging material is made to form a pillow-shaped preliminary shape container. The preliminary shape container is then cut, and a final shape container having a top, side walls and a bottom is formed by folding the packaging material along crease lines. Flaps are formed during the forming of the top of the container and are folded outwardly and downwardly onto side wall faces of the container. The top of the container is formed as a shed roof shape. The method of folding the flaps outwardly from the top of the container and the resulting shaped container allows attachment of a large spout with a wide mouth on the top, while achieving high speed manufacturability without subjecting the paper packaging material to high stresses.

The first flexible joint, the spring face, and the second flexible joint cooperate to enable the push-tab to move relative to the base of the apparatus. The air vent is adapted to facilitate a substantially even flow rate of a product through the opening of the closure apparatus.
