Patent number: 6692684Abstract: The disclosure relates to a method and an apparatus for producing a sterile packaging container from a thermoplastic blank or preform which, during stepwise displacement between different processing stations (A-H), is subjected to a first heating to a temperature suitable for a subsequent sterilization with the aid of a chemical sterilization agent in gas form. A subsequent, additional heating stage imparts to the blank the desired moulding temperature, whereafter the blank, after displacement to a blow moulding station, is blow moulded to the desired configuration with the aid of mould halves (9) surrounding the blank. Hereafter, the blank is displaced to a filling station (E) in which it is filled with the desired contents in order thereafter finally to be sealed with the aid of a wafer (17) and discharged out of the apparatus according to the present invention.Type: GrantFiled: August 7, 2000Date of Patent: February 17, 2004Assignee: Tetra Laval Holdings & Finance S.A.Inventors: Hans Nantin, Lars Mårtensson, Anders Andersson

Patent number: 5258162Abstract: 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.Type: GrantFiled: July 31, 1992Date of Patent: November 2, 1993Assignee: Tetra Alfa Holdings S.A.Inventors: Jan Andersson, Lars Martensson, Thomas Bjerborn, Goran Smith

Patent number: 5183644Abstract: 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.Type: GrantFiled: April 16, 1991Date of Patent: February 2, 1993Assignee: Tetra Alfa Holdings SAInventors: Lars Martensson, Jan Andersson

Patent number: 4861328Abstract: 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.Type: GrantFiled: December 21, 1988Date of Patent: August 29, 1989Assignee: AB Tetra PakInventors: Rickard Franke, Lars Martensson
