Patent number: 6315967Abstract: A process for crystallizing a thermoplastic preform or container which utilizes a preheated plug to provide the sole upright support for a workpiece in the crystallizing process. The preheated plug aids in the crystallization process by applying heat to the interior surface of the finish area while heat is also applied to the exterior surface of the finish area to crystallize the finish area. The thermoplastic preform or container is then cooled and removed from the plug.Type: GrantFiled: July 13, 2000Date of Patent: November 13, 2001Assignee: Schmalbach-Lubeca AGInventors: Terry C.

Patent number: 6309613Abstract: A machine for crystallizing a thermoplastic preform or container is constructed from modular subassemblies and utilizes a preheated plug to provide the sole upright support for a workpiece in the crystallizing process. The first modular subassembly includes the workpiece in-feed and plug preheat structures and incorporates the drive apparatus for the entire machine. The opposed end of the crystallizing machine is constructed of a subassembly which operates to provide the turnaround and tensioning takeup for the carrier mechanism transporting the workpieces. Positioned between the first subassembly and the opposed end subassembly are heating and cooling processing modules which can be provided in any number depending on the size constraints and workpiece quantity restraints desired. The processing modules provide the heating and crystallizing processes for the desired area of the workpiece and the cooling process of the workpiece prior to unloading.Type: GrantFiled: August 16, 2000Date of Patent: October 30, 2001Assignee: Schmalbach-Lubeca AGInventors: Terry C. Potter, Peter J. Hatas, Liguo Zhao

Patent number: 6277321Abstract: A wide-mouth, hot-fill plastic container having pinch-grips and a high push-up base and method for forming the same. According to the method, a preform is positioned in a mold cavity defined in part by surfaces which deviate substantially inward to form pinch-grips in the resulting container. Initially, a mold base is located so that it defines an initial mold cavity whose length is greater than the final length of the container. The preform is axially stretched in the cavity to a length greater than the containers final length. After stretching the preform, the preform is generally expanded radially outward under low pressure. The mold bottom is then moved to a position where the length of the cavity is about the same as the final length of the container. The preform is further expanded under high pressure such that it contacts the molding halves thereby forming the finished container.Type: GrantFiled: April 9, 1998Date of Patent: August 21, 2001Assignee: Schmalbach-Lubeca AGInventors: Dwayne G. Vailliencourt, Kerry W. Silvers

Patent number: 6223931Abstract: A closure end is provided, particularly made of sheet material for beverage cans, in which an annular fringe region is radially coupled between the central panel portion and a radius of curvature coupled to a core groove with an inner leg. The central panel portion is squeezed such that material is displaced (flows) from the fringe region in a substantially radial outward direction towards the radius of curvature. The squeezing is accomplished by a coining tool having a coining surface operable to contact the closure end. The closure surface is pressed against the closure end causing the thickness of the sheet material of the closure end to be reduced in the annular fringe region. The reduction in thickness gradually decreasing in the direction of the radius of curvature. The material displaced by the squeezing flowing towards the radius of curvature.Type: GrantFiled: September 20, 1999Date of Patent: May 1, 2001Assignee: Schmalbach-Lubeca AGInventors: Lutz Strube, Peter Hoft, Dieter Heinecke

Patent number: 6202880Abstract: An openable can end for a beverage can of usual type, having a first tear-out portion which seems to be openable, when a lever-type tab is operated. A second tear-out portion is also provided beside or outside the first portion, wherein the second tear-out portion tears out (or breaks in) instead of the expected first tear-out portion. Thus, it is possible to surprise the user upon opening such a beverage can, without impairing the simple and reliable opening of the beverage can.Type: GrantFiled: July 6, 1998Date of Patent: March 20, 2001Assignee: Schmalbach-Lubeca AGInventors: Lutz Strube, Richard Reichinger

Patent number: 6129494Abstract: Sealant is applied onto or into a folded-seam closure of a metal can. Instead of introducing sealant into the U-shaped lid flange and drying, according to the invention the compound or sealant is applied to the base flange, the base of the metal can being dipped into a current of fluid sealant or at least brought into contact with it at the surface. This substantially improves the precision of dosing and the exact amount of applied sealant.Type: GrantFiled: August 20, 1997Date of Patent: October 10, 2000Assignee: Schmalbach-Lubeca AGInventors: Reinhard Kutschan, Hellmut Bunsch

Patent number: 6123493Abstract: Tooling for use with a folded cover seaming machine having a seaming chuck with a profile and a corresponding movable seaming roller formed with a mating profile operable to couple a can end to the walls of a can. The cross sectional thickness of the seaming roller in the transition area is reduced and the corresponding cross sectional thickness of the seaming chuck is increased. The increased thickness of the seaming chuck provides additional strength thereby reducing the occurrence of structural defects or fissures in the seaming chuck. The deceased thickness of the seaming roller provides a contour which minimizes the possibility of damage to cans and jamming of the seaming machine due to jamming in cases where no can end is supplied.Type: GrantFiled: February 1, 1999Date of Patent: September 26, 2000Assignee: Schmalbach-Lubeca AGInventor: Hans-Dietrich Politt

Patent number: 6016932Abstract: A blow molded, thin walled plastic container for filling with a liquid whose temperature is elevated above ambient. The container includes a first portion of a first diameter, a second portion of a second diameter, and reduced diameter region between the first and second portions. The reduced diameter portion extends circumferentially around the container and a plurality of ribs which are located to extend between the first and second portions. The ribs form reinforcing members in the reduced diameter portion and increase the top load capabilities of the container. The first and second portions can both be formed in the shoulder portion of the container or one in the shoulder portion and one in the sidewall of the container.Type: GrantFiled: November 4, 1998Date of Patent: January 25, 2000Assignee: Schmalbach-Lubeca AGInventors: Kevin D.

Patent number: 5947673Abstract: An improvement in the shape of a fold in a tin can allows the use of sheet metal of lower gauge than that currently used. This is achieved with a fold geometry on a tin can which is closed off with a double fold, such as for a drink or food tin; by providing a continuous or stepped contour on the fold side; and by insuring that the lid hook is clearly in area-contact (positive fit) on its outer side with the free end of the body hook in its lower third. The invention may be applied to standard-gauge as well as thinner-gauge sheet metal, and generally results in a better seal.Type: GrantFiled: May 13, 1997Date of Patent: September 7, 1999Assignee: Schmalbach-Lubeca AGInventor: Lutz Strube
