Patent number: 10435223Abstract: A plastic container comprises an upper portion including a finish defining an opening into the container, a lower portion including a base defining a standing surface, a sidewall extending between the upper portion and the lower portion, the sidewall defining a longitudinal axis, and at least one substantially transversely-oriented pressure panel located in the lower portion. The pressure panel is movable between an outwardly-inclined position and an inwardly-inclined position to compensate for a change of pressure inside the container. The standing surface defines a standing plane, and the entire pressure panel is located between the standing plane and the upper portion of the container when the pressure panel is in the outwardly-inclined position.Type: GrantFiled: March 18, 2016Date of Patent: October 8, 2019Assignee: CO2PAC LimitedInventors: David Melrose, John Denner, Paul Kelley, Gregory Trude

Publication number: 20180215494Abstract: A blow molded plastic container is provided. The container has a body section having a substantially non-circular cross-sectional shape, the body section having an enclosed bottom portion that forms a bottom end of the container and substantially flat side portions extending upwardly from the bottom end; a finish defining an opening; and a dome extending from the body section to the finish. The dome includes at least one stiffening structure formed by an inwardly indented, vertically extending groove.Type: ApplicationFiled: January 29, 2018Publication date: August 2, 2018Applicant: GRAHAM PACKAGING COMPANY, L.P.Inventors: John E. Denner, Gregory A. Trude, Paul V. Kelley, Richard K. Ogg, Seungyeol Hong, David Melrose

Patent number: 9878816Abstract: A plastic container comprises an upper portion including a finish adapted to receive a closure, a lower portion including a base, and a sidewall extending between the upper portion and the lower portion. The upper portion, the lower portion, and the sidewall define an interior volume for storing liquid contents. The plastic container further comprises a pressure panel located on the container and moveable between an initial position and an activated position. The pressure panel is located in the initial position prior to filling the container, and is moved to the activated position after filling and sealing the container. Moving the pressure panel from the initial position to the activated position reduces the internal volume of the container and creates a positive pressure inside the container. The positive pressure reinforces the sidewall. A method of processing a container is also disclosed.Type: GrantFiled: December 29, 2013Date of Patent: January 30, 2018Assignee: CO2 PAC LTDInventors: David Melrose, Paul Kelley, John Denner

Patent number: 9162807Abstract: An improved blow molded plastic container having generally rounded sidewalls that are adapted for hot-fill applications has two adjacent sides and two pairs of controlled deflection panels, each pair reacting to vacuum pressure at differing rates of movement, whereby one pair inverts under vacuum pressure and the other pair remains available for increased squeezability or extreme vacuum extraction. The opposing sidewalls are symmetric relative to vacuum panel and rib shape and placement. The ribs and controlled deflection panels cooperate to retain container shape upon filling and cooling and also improves bumper denting resistance, decreases vacuum pressure within the container, and increases light weight capability.Type: GrantFiled: January 24, 2012Date of Patent: October 20, 2015Assignees: Graham Packaging Company, L.P.Inventors: David Melrose, Paul Kelley, Scott Bysick, Justin Howell

Patent number: 9145223Abstract: A container has a longitudinal axis, and comprises an upper portion including an opening into the container, a sidewall portion extending from the upper portion to a lower portion, the lower portion including a base, and a pressure panel located in the lower portion substantially transversely to the longitudinal axis, the pressure panel being movable substantially along the longitudinal axis between an initial position and an inverted position to compensate for a change of pressure induced within the container. The pressure panel comprises an initiator portion and a control portion, the initiator portion adapted to move in response to the change of pressure prior to the control portion.Type: GrantFiled: March 5, 2012Date of Patent: September 29, 2015Assignee: CO2 PAC LIMITEDInventors: David Melrose, John Denner, Paul Kelley
