A ratio of said first surface area to said second surface area is at least 1.0, thereby ensuring superior label support. The main body portion further has a maximum outer radius and a maximum depth that is defined with respect to the maximum outer radius. A ratio of the maximum depth to the maximum outer radius is preferably no greater than about 0.2, which also contributes to the quality of the label support. | 03-31-2011 |

Each of the waves extends radially outwardly from the central region to the vertical rise portion. The main body portion is shaped so as to have a plurality of sidewall portions that are bounded by a plurality of vertically extending edge portions. In one embodiment, at least one of the vertically extending edge portions may have at least one inwardly extending gusset defined therein to provide structural reinforcement. | 04-07-2011 |
20110079575 | PASTEURIZABLE AND HOT-FILLABLE PLASTIC CONTAINER - A blow molded plastic container for hot fill and pasteurization uses includes a main body portion that is shaped so as to be substantially round in horizontal cross-section and a base portion. The base portion is shaped to define a generally circular standing ring and an elevated push-up portion that is positioned radially inward of the standing ring. The push-up portion includes a central region, an annular, substantially straight and substantially vertical rise portion that is positioned immediately radially inward of the standing ring and a plurality of radially oriented waves. Each of the waves extends radially outwardly from the central region to the vertical rise portion and is preferably shaped so as to subtend a substantially constant angle along its length. | 04-07-2011 |
