ABSTRACT:
A non-round base structure for a hot-fill plastic container provides the container with enhanced structural integrity. The base structure is roughly rectangular and is composed of a flexible vacuum absorbing area and a bearing edge which support the container in an upright position. The flexible vacuum absorbing area abates with a central ellipse shaped push-up, which is a concave surface. A series of ribs with an outward facing rounded edges are fashioned on the concave surface. The ribs extend outwardly from the center of the ellipse. The disclosed base structure enables the container to withstand the various forces encountered in filling, cooling and handling.
