Abstract: An improved plastic container including a bottom strengthening formation. The strengthening formation assists in reducing deformation of the bottom of the container when the container is pierced during the beverage brewing process. In a preferred embodiment, the strengthening formation includes a generally gear-shaped path to evenly distribute dynamic forces from a piercing needle or stylus to the spokes or gear teeth of the strengthening formation. The gear-shaped path includes the features of gear design and includes an outer diameter, and inner diameter, and a pitch diameter. In some embodiments, a depression defining and encircling the piercable area further enhances the even distribution of dynamic forces.

Abstract: A container is provided with a flange defining a container opening that may help expunge food product as the film and seal head comes down on the container flange. The flange of the container opening has a predetermined angle. The container flange with its sealing surface generally deflects or angularly pivots when sealed with the film during the sealing process. The container flange and film may push product contamination from the sealing surfaces inwardly into the container. The flange may be continuous about the periphery of the container opening.
