Publication number: 20110290810Abstract: A dual constituent container includes a compartment for liquids and an elongate inwardly directed recess open to the container exterior and isolated from the compartment. The container is formed by blow molding, using a mold that incorporates a shaping feature projected longitudinally into the mold cavity. The shaping feature incorporates an arrangement of longitudinal channels having a channel width such that when a thermoplastic preform is expanded into contact with the mold cavity walls and the shaping feature, portions of the expanded preform span the channels and cooperate with the channels to provide passages that accommodate pressurized air to facilitate separation of the expanded preform from the shaping feature. The same portions of the expanded preform can partially protrude into the channels, thus to form longitudinal ribs along the recess which aid in frictionally holding a secondary constituent.Type: ApplicationFiled: August 15, 2011Publication date: December 1, 2011Applicant: EMERGENT TECHNOLOGIES, LLCInventors: Gregory J. Tilton, Martin T. Geithmann, Thomas J. Carros, Scott W. Steele

Patent number: 7354538Abstract: A system and a method for controlling a container manufacturing machine include a thickness monitor (10) for determining an average wall thickness of containers produced by the machine. The system uses the average wall thickness to adjust machine control to change operation of the machine and adjust the quality of the containers being produced. The system also responds to feedback from pneumatic devices (104), heaters (103), mechanical devices and temperature sensors (108, 109) to determine corrections to be made to the machine operation.Type: GrantFiled: June 10, 2004Date of Patent: April 8, 2008Assignee: Petwall, LLCInventors: Frank E. Semersky, Ronald A. Puvak, Scott W. Steele, Donald Wayne Miller, William E. Schmidt

Patent number: 4571173Abstract: A method is disclosed for thermally conditioning an essentially tubular parison of polyethylene terephthalate material to a desired orientation temperature at which the polyethylene terephthalate material can be biaxially stretched. The method comprises the steps of heating the parison by applying heat to the exterior surface thereof until the surface reaches a maximum heating temperature less than the temperature at which the polyethylene terephthalate material begins to crystalize and then cooling the heated exterior surface of the parison to remove the heat therefrom while the heat within the wall of the parison diffuses therethrough to raise the temperature of the opposing interior surface toward the desired orientation temperature.Type: GrantFiled: September 20, 1984Date of Patent: February 18, 1986Assignee: Owens-Illinois, Inc.Inventors: Long F. Chang, Scott W. Steele
