20100140838 | Method of Making Plastic Container Having A Deep-Inset Base - A method of plastic container having a deep inset base of the type that has a standing ring for supporting the container on a flat surface includes steps of molding a container blank having a standing ring and a base projection portion that is formed beneath the standing ring and relatively displacing the base projection portion upwardly with respect to the standing ring until the base projection portion is positioned above the standing ring. An improved plastic container having a deep inset base is also disclosed. | 06-10-2010 |
20100170199 | Method and System for Handling Containers - Method and system for handling a plurality of hot-filled and capped containers having temporary deformations or distortions caused by vacuums induced in the containers. For each container, temporary deformations are confined or directed to a particular portion of the container. Annular hoop rings can be provided to confine the temporary deformations to a smooth sidewall portion of the container between the annular hoop rings. Alternatively, one or more supplemental vacuum panels can be provided to confine or direct the temporary deformation thereto. The annular hoop rings and the one or more supplemental vacuum panels can provide for substantially stable touch points for the container. The containers are conveyed with temporary deformations such that substantially stable contact points of each container are in contact with corresponding substantially stable contact points of other containers. After the conveying, a moveable element in a bottom end of each container is activated substantially permanently to remove the vacuum in the container. | 07-08-2010 |

20130306660 | HOT FILL CONTAINER HAVING SUPERIOR CRUSH RESISTANCE - A hot fill plastic container has a dome portion with a convex outer surface that defines a maximum outer diameter of the container so as to extend outwardly beyond a main body portion of the container. The generally egg-shaped dome portion enhances the crush resistance of the dome and provides a point of contact between containers when they are placed adjacent to one another. A circumferential stiffening groove may be provided near a lower end of the dome portion. | 11-21-2013 |
