20090261058 | Volumetrically Efficient Hot-Fill Type Container - A volumetrically efficient plastic hot fill container at least one vacuum panel defined by a vacuum panel area of a sidewall that is constructed and arranged to flex inwardly in order to accommodate volumetric shrinkage that may occur within the container as a result of the conventionally known hot fill process. Advantageously, at least a portion of the vacuum panel area of the sidewall is formed as a plurality of undulations. The undulations preferably have a vertical component and provide an increased surface area to the vacuum panel area relative to what a flat surface would provide. As a result, the amount of volumetric shrinkage that may be accommodated through inward deflection of said vacuum panel area of said sidewall is increased relative to a flat surface would provide. | 10-22-2009 |
20090261059 | Volumetrically Efficient Hot-Fill Type Container - A volumetrically efficient plastic hot fill container at least one vacuum panel defined by a vacuum panel area of a sidewall that is constructed and arranged to flex inwardly in order to accommodate volumetric shrinkage that may occur within the container as a result of the conventionally known hot fill process. Advantageously, at least a portion of the vacuum panel area of the sidewall is formed as a plurality of undulations. The undulations preferably have a horizontal component and provide an increased surface area to the vacuum panel area relative to what a flat surface would provide. As a result, the amount of volumetric shrinkage that may be accommodated through inward deflection of said vacuum panel area of said sidewall is increased relative to a flat surface would provide. | 10-22-2009 |
20090294399 | Hot Fill Container Having Improved Vacuum Panel Configuration - A hot fill container of the type that is used package fruit juices and other beverages includes a vacuum panel configuration that provides optimal volumetric efficiency, material usage and container strength and is particularly suited for use with smaller containers. The vacuum panel configuration includes a plurality of cageless vacuum panels that are separated by longitudinally extending outwardly projecting creases that are defined in a sidewall of the container. This arrangement maximizes the effective surface area of the vacuum panels relative to the external surface area of the container. Each of the longitudinally extending outwardly projecting creases has a curved outer surface that is convex when viewed in longitudinal cross-section. The cageless vacuum panels are constructed and arranged to be convexly curved when a pressure within the container is equal to an external pressure, but become concavely curved when a predetermined partial vacuum condition exists within said container. | 12-03-2009 |
20100270259 | Container With Rib Elements Patterned in a Brick Pattern - A container for beverages has a plurality of side panels having rib elements. The container preferably has the rib elements arranged in a brick pattern. The container reduces the deformation of the side panels that occurs when gripped. | 10-28-2010 |
20110049084 | Dome Shaped Hot-Fill Container - A container has a domed shaped top portion that is located above the body portion. The body portion connects with the domed shaped top portion via a shoulder portion that has a variable distance from the longitudinal axis of the container. | 03-03-2011 |
20110084046 | PLASTIC CONTAINER HAVING IMPROVED FLEXIBLE PANEL - A plastic container that is adapted for adjustment to internal volumetric changes such as those that typically occur during the hot fill process includes a container body defining an internal space. The container body has a sidewall that is shaped to define at least one flexible panel. The flexible panel has a central longitudinal axis, an upper portion, a lower portion and a central portion. The central portion of the flexible panel has a width that is greater than a respective width of at least one of the upper and lower portions. The flexible panel is substantially flat as viewed in a longitudinal cross-section taken along the central longitudinal axis. Additionally, the central portion has a transverse radius of curvature that is greater than a transverse radius of curvature of at least one of the upper portion and said lower portion. Because the central portion represents the maximum width of the flexible panel, the efficiency of vacuum uptake is maximized with respect to conventional vacuum panels that are substantially flat in longitudinal cross-section. | 04-14-2011 |
20110132865 | PRESSURE RESISTANT MEDALLIONS FOR A PLASTIC CONTAINER - A container made of plastic material, such as PET, that is adapted to be hot-fillable. The container has flex panels located on its sides. The flex panels are surrounded by frames. The frames and the flex panels have medallions located on them to prevent creasing from occurring during the hot-fill process. | 06-09-2011 |
20110284493 | CONTAINER WITH BEND RESISTANT GRIPPABLE DOME - A plastic container having improved structural stability characteristics when gripped includes a finish and a main body having a sidewall. The main body has a lower portion and an upper dome that is separated from the lower portion by a waist. The upper dome includes an upper brow portion having a first maximum width and that has a concave recess defined therein. A gripping recess may be defined in the sidewall beneath the upper brow portion, which has a second minimum width that is less than the first maximum width. A portion of the sidewall that defines the gripping recess may have a substantially vertically oriented reinforcing element defined therein. In addition, a portion of the sidewall that defines the gripping recess may have U-shaped groove defined therein. | 11-24-2011 |
20120074151 | VACUUM RESISTANT RIBS FOR LIGHTWEIGHT BASE TECHNOLOGY CONTAINERS - A hot-fillable container that is cylindrical in shape. The container may have two ribs. A top rib is located in the top bumper and a bottom rib is located in the bottom bumper. Both the top and the bottom ribs have depth that is deep enough so that the container may withstand the hot-fill process and increase its top load ability. | 03-29-2012 |
20120219734 | BLOW MOLDED RECTANGULAR CONTAINER - An extrusion blow molded plastic container includes a main body portion and a finish portion that defines an opening. The finish portion has an upper surface and an outer surface on which a snap bead is defined. In order to prevent saddling of the upper surface, a plurality of grooves is defined in the outer surface, each of the grooves passing through the snap bead. In addition, the main body portion has an outer surface that defines a substantially rectangular shape with rounded corners when viewed in transverse cross-section. The outer surface of the finish portion also has a substantially rectangular shape with rounded corners when viewed in transverse cross-section. The shape of the finish portion when viewed in transverse cross-section is smaller than the shape of the main body portion. A ledge is defined between the outer surface of the main body portion and the outer surface of the finish portion. The ledge has a first width, adjacent to one of the rounded corners of the finish portion, which is greater than a second width that is not adjacent to one of the rounded corners of the finish portion. | 08-30-2012 |
