Patent number: 6612451Abstract: A blow molded container having a multi-functional base which enables use of the container in both hot-fill operations and pasteurization/retort operations and enables efficient vertical stacking of like containers. To this end, a portion of the base is capable of flexing upwardly and/or downwardly in response to variations in pressures in a filled and sealed container. Structurally, the base has a discontinuous concave outer annular wall forming a discontinuous standing ring and an inner annular wall functioning as a flex panel. The inner annular wall connects outwardly to a plurality of radial webs extending at an elevation above the standing ring and connects inwardly to an anti-inverting, upwardly-projecting dome. Preferably, a shoulder extends radially inward on the inward facing side of the outer annular wall above a level of the standing ring to facilitate vertical stacking of containers having like bases.Type: GrantFiled: April 17, 2002Date of Patent: September 2, 2003Assignee: Graham Packaging Company, L.P.Inventors: John W. Tobias, Richard K. Ogg

Patent number: 6393803Abstract: A process for blow-molding and coating plastic containers under conditions of positive control in a close-coupled, compact machine to enhance operational efficiency. According to one of the preferred methods, the containers are coated promptly after the containers are discharged from hot molds to take advantage of the residual heat of the freshly blown containers to enhance curing/drying of the coating and to enhance bonding of the coating to the container surface. According to another one of the preferred methods, the containers are aseptically filled and capped either before or after the containers are coated. Alternatively, the process can include hot-filling and capping of containers in which the containers are coated promptly after being hot-filled to take advantage of the elevated temperature of the hot-filled containers.Type: GrantFiled: November 5, 1999Date of Patent: May 28, 2002Assignee: Graham Packaging Company, L.P.Inventors: Gregory J. Luka, John W. Tobias

Patent number: 5931324Abstract: A blow-molded plastic container and a separately formed injection-molded plastic handle adapted to be ultrasonically welded together. A pattern of energy directors is located on one of the confronting welding areas of the handle and the container sidewall. The handle has an elongate grip defining a grip centerline and the energy directors are located on both sides of the grip centerline adjacent opposite ends of the elongate grip.Type: GrantFiled: April 21, 1997Date of Patent: August 3, 1999Assignee: Graham Packaging Company, L.P.Inventors: Crawford Lyons, Frank E.

Patent number: 5762221Abstract: A hot-fillable, blow-molded plastic container having a reinforced dome which controls dome distortion otherwise caused by forces associated with hot-filling and shipping. In one embodiment, the reinforced dome resists distortion, and in a second embodiment, the reinforced dome enhances ovalization distortion. The container dome is bell-shaped with an inwardly extending waist and has a plurality of vertically extending grooves passing through the waist. Each groove is inwardly concave and extends from below the waist to adjacent the finish. Arcuate lands are formed between the grooves, and optionally, can have panels with a textured pattern which add to the aesthetic appearance of the container and which provide further stiffening of the dome. When two grooves are utilized, ovalization distortion is enhanced, and when three or more grooves are utilized, distortion is prevented.Type: GrantFiled: July 23, 1996Date of Patent: June 9, 1998Assignee: Graham Packaging CorporationInventors: John W. Tobias, Richard Ogg

Patent number: 5683904Abstract: The disclosure relates to a generic class of ubiquitin-specific proteases which specifically cleave at the C-terminus of the ubiquitin moiety in a ubiquitin fusion protein irrespective of the size of the ubiquitin fusion protein. More specifically, the disclosure relates to ubiquitin-specific proteases of this class which have been isolated from a cell. The disclosure also relates to isolated DNA sequences encoding the proteases of this class.Type: GrantFiled: June 7, 1995Date of Patent: November 4, 1997Assignee: Massachusetts Institute of TechnologyInventors: Rohan T. Baker, John W. Tobias, Alexander Varshavsky

Patent number: 5678711Abstract: A reinforced finish is on a blow-molded container. An insert is permanently attached on the finish of a preform from which the container is blown, or directly on the finish of the blow-molded container. The insert is ring-shaped, forms a portion of the top surface of the finish, is made from a rigid plastic material, and is positioned entirely above the threads.Type: GrantFiled: March 8, 1996Date of Patent: October 21, 1997Assignee: Graham Packaging CorporationInventor: John W. Tobias

Patent number: 5598941Abstract: A hot-fillable, blow-molded container has a grip panel structure which resists inverting when the container is filled with a hot liquid and after the container has been capped. The container and grip panel structure retain their aesthetic appearance and their structural integrity through use by the consumer.Type: GrantFiled: August 8, 1995Date of Patent: February 4, 1997Assignee: Graham Packaging CorporationInventors: Frank E.

Patent number: 5391490Abstract: A ubiquitin-specific protease which cleaves ubiquitin from any protein or peptide to which ubiquitin is joined and the gene encoding the protease are disclosed. The protease specifically cleaves the peptide bond in a fusion of ubiquitin to a protein or peptide between the carboxyl-terminal amino acid residue of a ubiquitin moiety and the .alpha.-amino group of any non-ubiquitin protein or peptide to which ubiquitin is joined. Recombinant expression vectors containing a DNA sequence encoding the ubiquitin-specific protease can be used to transform cells for production of the protease or to provide the cell with the ability to proteolytically deubiquitinate, in vivo, ubiquitin fusions co-produced by the cell. The protease can also be isolated and used to deubiquitinate ubiquitin fusions in vitro.Type: GrantFiled: January 25, 1994Date of Patent: February 21, 1995Assignee: Massachusetts Institute of TechnologyInventors: Alexander J.
