Abstract:
1. A method of processing a container with a separate base cup structure for removing vacuum pressure, said container having a longitudinal axis and at least one vacuum panel at a bottom end-wall of said container, said vacuum panel being moveable from an upwardly inclined position to, and from, a downwardly inclined position, said container having a geometrically unstable configuration when said vacuum panel is in said downwardly inclined position, said container having a geometrically stable configuration when positioned in said base cup structure, said method including: positioning said container in said base cup structure; with said container positioned in said base cup and said vacuum panel in an upwardly inclined position, applying a first longitudinally directed force against said upwardly inclined vacuum panel using a first actuating means to move said vacuum panel to a downwardly inclined position; hot-filling said container with said vacuum panel in said downwardly inclined position; and with said container positioned in said base cup structure, applying a second longitudinally directed force against said downwardly inclined vacuum panel using a second actuating means to move said vacuum panel to said upwardly inclined position.
