20090134117 | Container Having Vacuum Compensation Elements - A lightweight container includes an enclosed base, an upper portion that extends upwardly to a finish; and a body located between the base and the upper portion. The sidewall includes vacuum compensation elements that have an open end and an opposing closed end, and that form a V-shape. Each element has nested fields. | 05-28-2009 |
20090184127 | CIRCUMFERENTIAL RIB - A container has plural vacuum panels ( | 07-23-2009 |
20090242575 | CONTAINER BASE HAVING VOLUME ABSORPTION PANEL - A plastic container is provided having a container body and a closed base. The base includes a base body and a plurality of deflection ribs configured to buckle as the base deforms in response to an increase in negative pressure internal to the container. | 10-01-2009 |
20100176081 | CONTAINER HAVING META-STABLE PANELS - A container has meta-stable panels to compensate for internal vacuum from hot filling. The panels include a groove that yields during deformation such that the stiffness of the panel varies from its pre-yield stage to its post-yield stage. | 07-15-2010 |
20100219153 | CONTAINER HAVING VACUUM COMPENSATION ELEMENTS - A lightweight container includes an enclosed base, an upper portion that extends upwardly to a finish; and a body located between the base and the upper portion. The sidewall includes vacuum compensation elements that have an open end and an opposing closed end, and that form a V-shape. Each element has nested fields. | 09-02-2010 |
20100219154 | CONTAINER HAVING VACUUM COMPENSATION ELEMENTS - A lightweight container includes an enclosed base, an upper portion that extends upwardly to a finish; and a body located between the base and the upper portion. The sidewall includes vacuum compensation elements having a series of arches that are arranged to resemble water ripples formed by a water droplet. | 09-02-2010 |
20120061410 | HOT-FILL CONTAINER PROVIDING VERTICAL, VACUUM COMPENSATION - Provided is a hot-fill container adapted to provide vertical vacuum compensation in response to negative pressure inside the container. The container comprises one or more horizontal ribs that are configured to diminish in height in response to vacuum conditions inside the container. Each rib comprises an upper wall connected to a lower wall. The upper and lower walls are inclined from a horizontal reference line and adapted to hinge with respect to each other to provide vertical vacuum compensation. | 03-15-2012 |
20140048508 | CONTAINER BASE HAVING VOLUME ABSORPTION PANEL - A plastic container configured to deform from an as-molded state in response to negative internal pressure, the plastic container including a substantially cylindrical container body; and a base connected to a bottom portion of the container body, the base including a standing member, a substantially central hub, and a base body extending between the standing member and the hub, wherein the base body includes a deflection rib projecting up from the base body, the rib configured to deflect when the base body deforms in response to an increase in negative internal pressure. | 02-20-2014 |
