Abstract
A method is described for shaping the bottom of hot-filled containers, in which the bottoms of the containers are forced inwardly from a state bulged outwardly, in particular as they cool down. Complex mechanisms for forcing the bottom inwardly are dispensable for the reason that the bottoms are forced inwardly by at least one fluid jet and/or fluid pressure wave. In addition, shaping the bottom can advantageously be carried out in a production region immediately downstream of a closer.
Claims16
A method for shaping a bottom of hot-filled and closed containers, where said bottoms of said containers are forced inwardly from a quasi-stable state bulged outwardly, which is dimensionally stable without the action of an external overpressure onto said bottom, and in which the bottoms are bulged outwardly only to such an extent that the bottles can stand on a transport device, wherein said bottoms are forced inwardly by at least one fluid jet and/or a fluid pressure wave, where said bottoms are forced inwardly by a jet of water.
A method for shaping a bottom of hot-filled containers, where said bottoms of said containers are forced inwardly from a quasi-stable state bulged outwardly, which is dimensionally stable without the action of an external overpressure onto said bottom, wherein said bottoms are forced inwardly by at least one fluid jet and/or a fluid pressure wave, where said bottoms are forced inwardly by a shock wave.
A method for shaping a bottom of hot-filled containers, where said bottoms of said containers are forced inwardly from a quasi-stable state bulged outwardly, which is dimensionally stable without the action of an external overpressure onto said bottom, wherein said bottoms are forced inwardly by at least one fluid jet and/or a fluid pressure wave, where said at least one fluid jet and/or said fluid pressure wave are directed onto said bottoms when said containers are in a lying orientation.
A method for shaping a bottom of hot-filled containers, where said bottoms of said containers are forced inwardly from a quasi-stable state bulged outwardly, which is dimensionally stable without the action of an external overpressure onto said bottom, wherein said bottoms are forced inwardly by at least one fluid jet and/or a fluid pressure wave, and where said fluid jet and/or said fluid pressure wave are directed onto said bottoms when said containers are transported upside down.
