Abstract: The invention refers to a device (1) and method for sterilizing partly formed packages (6) in a packaging machine. The device (1) comprises an inner chamber (2) and an outer chamber (3), the inner chamber (2) being provided with a sterilization unit (5). Further, it comprises a carrier unit (10), comprising a separating member (11) and a package carrying member (12), which is being adapted to rotate between a first position in which the package carrying member (12) is located in the outer chamber (3), and in which the separating member (11) separates the inner chamber (2) from the outer chamber (3), and a second position in which the carrier unit (10) has rotated a package (6) into the inner chamber (2) and in which the separating member (11) separates the inner chamber (2) from the outer chamber (3).

Abstract: A device for sterilization in production of packages (8) is adapted for sterilization with a gaseous sterilizing agent which is kept in the gaseous phase throughout the sterilization process. The device comprises a heating zone (2), a sterilization zone (3) and a venting zone (4). It further comprises means for maintaining a higher pressure in the sterilization zone (3) than in the heating zone (2) and venting zone (4). A method of sterilizing packages (8) in production of the packages (8) is also disclosed. The packages (8) have an open end (11) and a closed end (12) A gaseous sterilizing agent is used and kept in the gaseous phase throughout the sterilization process. A positive pressure is maintained in a sterilization zone (3) in which the sterilization is performed.

Abstract: A method of sterilizing packages in production of the packages, wherein the packages have an open end and a closed end. A gaseous sterilizing agent is used and kept in the gaseous phase throughout the sterilization process and an ambient temperature and a concentration of sterilizing agent in a sterilization zone where sterilization is performed are measured and used for controlling the amount of sterilizing agent introduced in the sterilization zone.

Abstract: A method of producing a gaseous, hydrogen peroxide-containing sterilization fluid displaying good, uniform sterilization properties is disclosed. The method includes vaporizing liquefied hydrogen peroxide by injecting the liquefied hydrogen peroxide intermittently in finely-divided form into an air current which serves as a vaporization agent, wherein the air current is kept at a constant or insignificantly varying elevated vaporization temperature. An even vaporization temperature of the air current is ensured because the air, prior to vaporization, is heated by heat exchange with a heating element having a large mass or thermal capacity and a large heat exchange surface area which is kept at the desired elevated temperature by regulated energy supplied to the heating element. During breaks in vaporization between the intermittent injection of the liquefied hydrogen peroxide, the heat exchange surface area is heated with the aid of heat stored in the heating element.

Abstract: An apparatus for treating a package container blank with a fluid is disclosed and includes a rotary portion provided with a plurality of chambers for receiving the blanks and a fixed portion having a stator surface that faces the rotary portion. The fixed portion is provided with an arrangement that opens to the stator surface for supplying fluid so that upon successive rotations of the rotary member, the chambers will successively align with the arrangement for supplying fluid so that fluid is thereby supplied to the chambers.

Abstract: A mandrel used in a packaging machine being in a tubular shape and provided with a cooling chamber at one end so as to cool a plain plate which is positioned at the top of the mandrel and contacts the heated, infolded and compressed bottom of a tubular package carton blank. Four projections are formed on the outer surface of the mandrel so as to contact each corner of the tubular package carton blank to leave it open. A pair of water cooling pipes are provided in the tubular mandrel with a space left between the internal wall of the tubular mandrel and connected to the cooling chamber so that only the bottom of the heat-sealed container made of a tubular package carton blank with thermoplastic coatings thereon is cooled and the side walls of the container are free from moisture condensation.
