Patent number: 6216915Abstract: A dual chamber package for containing and simultaneously dispensing two individually contained fluent products which are not continuously externally pressurized. The package has an outer container body formed of a resilient plastic material, which is closed at one end, and a pair of collapsible containers contained within the outer container body for containing the fluent products out of contact with one another. A single elevator is positioned in within outer container body, initially near the closed end thereof, and in contact with closed ends of each of the collapsible containers. The elevator receives the free end of a walking stick in a one-way connection, and lifting of the walking stick causes the elevator to rise, thereby simultaneously dispensing small doses of the packaged products from the collapsible containers.Type: GrantFiled: August 24, 1999Date of Patent: April 17, 2001Assignee: Owens-Brockway Plastic Products Inc.Inventors: Robert E. Harman, Jeffrey J. Baltzell, Craig E. McClean

Patent number: 6213756Abstract: Extrusion blow molding apparatus (10) having a blow mold (12), a neck mold (14) positioned above the blow mold and an anvil (30) positioned in an outwardly facing cavity (32) of the neck mold. A container (C) is produced in the molding apparatus from a parison of a heated thermoplastic material by introducing pressurized blowing fluid into the container being formed by way of a blow pin assembly (16) that is reciprocable relative to the blow mold. The blow pin assembly has an inner tubular member (20) with a free end that is within the container during blowing, and an outer tubular member (22) that surrounds the inner tubular member and defines an annulus therewith for withdrawing spent blowing fluid from the container. The outer tubular member has radial ports (24) for directing spent blowing fluid against a moil (M) being formed at a rim (R) of a finish (F) of the container.Type: GrantFiled: April 8, 1999Date of Patent: April 10, 2001Assignee: Owens-Brockway Plastic Products Inc.Inventors: Theodore M. Czesak, Thomas J. Krall, William P. Atkins

Patent number: 6171542Abstract: Wheel molding apparatus for molding thermoplastic containers or other articles, the apparatus having a multiplicity of sets (10) of opposed, separable radially aligned mold halves (12, 14) that travel in a circular path about a horizontal axis. The inner of the mold halves (14) is separated from the outer of the mold halves (12) at the 12:00 o'clock position of the mold set that includes such mold halves to permit the molded article to be ejected from the mold set. However, the ejection of the molded article should not take place until after the separation of the mold halves, and this requires that the molded article be positively retained within the outer mold half until it is desired to eject the article therefrom.Type: GrantFiled: May 6, 1999Date of Patent: January 9, 2001Assignee: Owens-Brockway Plastic Products Inc.Inventor: Douglas S. Struble

Patent number: 6127011Abstract: In a method and apparatus wherein a container is formed, decorated by rotating the container and then the base of the contianer is cut off for a plastic tube, a container is formed with a diametral lug on the base to facilitate rotating the container during decorating. In another form, opposed diametral surfaces are provided on the lower end of the container adjacent the base. In another form, the diametral surfaces are arcuate. In another form, the lower end of the container includes a frustoconical surface. In another form, circumferentially spaced axial grooves are provided in the frustoconical surface.Type: GrantFiled: June 3, 1998Date of Patent: October 3, 2000Assignee: Owens-Brockway Plastics Products Inc.Inventors: Roger P. Smith, Thomas J. Krall, Jeffery S. Lugar, Michael D. Norton

Patent number: 6123231Abstract: A one-piece self-draining container and method and apparatus for forming same. The container includes a body and a finish wall extending upwardly from a body opening. The finish wall surrounds a dispensing spout which extends above the top of the wall. A frustoconical web joins the finish wall and the dispensing spout to form a drain apron gutter channel having a relatively steeply inclined cone angle. A drain opening is defined adjacent the channel for draining fluid from the channel into the container body. A removable cap having a depending skirt defining a thread which mates with an internal thread on the container wall to thereby threadably engage and close the container. The method is performed on the type of extrusion-injection blow molding machine as generally disclosed in U.S. Pat. No. 2,804,654 as modified in accordance with the invention to form the web wall in situ with a frustoconical configuration of uniform cross sectional thickness.Type: GrantFiled: July 13, 1998Date of Patent: September 26, 2000Assignee: Owens-Brockway Plastic Products Inc.Inventor: Gregory A. Geisinger

Patent number: 6116888Abstract: Improved blow-molding prototype molding system, method and apparatus wherein a plastic container is first designed using computer-aided design (CAD) software to produce a geometric computer software model of a hollow plastic container of desired contour. This model is then used to generate a geometric computer software model of a corresponding mold cavity. This data file in turn provides the control signal for a cutting tool of a CNC three axis mold machining tool operating on a starting blank for each mold half of metal material having predetermined and constant length, width and thickness outside dimensions. A mold cavity is thereby automatically machined in a front face of this blank that constitutes one of the two major and parallel face planes of the mold half block. The other half of the mold cavity is similarly formed in the front face of a second mold half block that cooperates with the first mold block to form the two mold halves of a complete blow mold.Type: GrantFiled: July 29, 1998Date of Patent: September 12, 2000Assignee: Owens-Brockway Plastic Products Inc.Inventors: Richard R. Johnston, Theodore M. Czesak, Anthony J. Scott, Igor F. Beaufils

Patent number: 6105800Abstract: A blown plastic container that includes a hollow plastic body, an integral blow-molded neck and an integral blow-molded finish with a radially outwardly extending blow-molded thread or bead for retaining a closure on the finish. Reinforcement is provided between the thread or bead and a ledge on the finish to prevent collapse of the finish when a closure is applied to the finish. In one form, this reinforcement includes blow-molded axial columns extending radially outwardly. In another form, the reinforcement includes geometric depressions. Preferably, the reinforcement is disposed circumferentially at equal spacing. When the container is trimmed, the finish may have an annular frustoconical radial ledge spaced form the open end of the finish. The reinforcement extends between the ledge and the lowest thread or bead, between the thread or bead, or for the full height of the finish above the ledge.Type: GrantFiled: October 10, 1997Date of Patent: August 22, 2000Assignee: Owens-Brockway Plastic Products Inc.Inventor: Theodore M.

Patent number: 6083342Abstract: A system and method for rapidly labeling a blow-molded hollow container made of a plastic composition subject to out-gassing after de-molding. Otherwise, conventional high speed silk screen labeling technology and processing is employed shortly after container fabrication de-molding in order to accurately deposit a continuous liquid layer of conventional silk screen ink over an external container surface area designated for application thereon of a self-adhering pre-printed label. The label is rapidly and accurately transfer applied over the silk screen coated area immediately after the same has dried, and even while out-gassing is still occurring from the de-molded to container. However, the protective ink barrier coating prevents formation of bubbles beneath the label. Those gases in the container wall resident beneath the label-affixed area can then nevertheless out-gas by migrating out of the container internal wall surface.Type: GrantFiled: March 18, 1998Date of Patent: July 4, 2000Assignee: Owens-Brockway Plastic Products Inc.Inventor: Eugene J. Frey
