A method for hot-filling a polymeric container with heated product. The method includes mechanically inverting a base of the polymeric container prior to the heated product cooling in order to create a positive pressure within the container prior to cooling, and a vacuum in the container after cooling.

A container including an opening defined by a finish portion. A base is at an end of the container opposite to the opening. The base includes a deep base ring between a standing surface and a truncated cone at a center of the base. The truncated cone is mechanically movable a displacement distance from an as-blown position to a displaced position subsequent to hot-filling and capping of the container to reduce an internal volume of the container. In the displaced position, the truncated cone is closer to the opening than in the as-blown position.

A plastic container comprising a container body comprising a bottom portion, an upper portion, a sidewall portion extending between the upper portion and the bottom portion, and a finish portion. The container body having a chamber defined therein. The finish portion extends from the upper portion and defines a mouth in fluid communication with the chamber. The bottom portion including a base portion comprising (i) a support surface, (ii) a plurality of ribs, (iii) a plurality of voids, and (iv) an inner core aligned with a central axis of the container body. The inner core including a contoured wall portion, a first radiused wall portion adjacent the contoured wall portion, and a second radiused wall portion adjacent the first radiused wall portion. The bottom portion is configured to permit a region of said base portion to move in response to a pressure differential.

Hot-fillable plastic bottle including a finished portion, a body portion with at least one circumferential rib configured to resist radial distortion, and a base portion. The base portion comprises a base sidewall, a bottom support surface extending radially inward from the base sidewall and defining a reference plane, an inner support wall extending upwardly from the bottom support surface, and a diaphragm extending radially inward from the inner support wall. The diaphragm comprises an inner wall having an arcuate shape with a radius r1 and a central conical structure, where the diaphragm is in an initial as-formed position with the conical structure above the reference place. The diaphragm is configured to move from an initial as-formed position toward a second position when an internal pressure relative an external pressure exceeds a threshold value.

A plastic container includes a container body having a bottom portion, a sidewall portion, and an upper portion, with a chamber defined therein. The sidewall portion includes at least one circumferential indent. The bottom portion includes a support surface and a base portion including a first and second plurality of ribs and other structures that permit a region of the base portion to move in a dynamic and variable manner in response to certain forces and other conditions present during various fluid processing stages associated with filling, sealing, and cooling the container.

A container including an opening defined by a finish portion. A base is at an end of the container opposite to the opening. The base includes a deep base ring between a standing surface and a truncated cone at a center of the base. The truncated cone is mechanically movable a displacement distance from an as-blown position to a displaced position subsequent to hot-filling and capping of the container to reduce an internal volume of the container. In the displaced position, the truncated cone is closer to the opening than in the as-blown position.

A method of processing a plastic container to increase internal pressure including blow-molding the container to comprise an invertible panel in the base and a standing ring, hot filling and sealing the container, feeding the container into an apparatus with a holding device and forcing a volume reduction and pressure increase into the container, and stacking the containers in bulk pallets on top of one another to increase top load and create a positive pressure within the distribution load of containers.

Described are containers and moulds for producing containers. The container is obtained by blow moulding or stretch blow moulding from a blank made of plastic material. The container includes a body, a shoulder extending from the shoulder, and a bottom at the lower end of said body. The shoulder is articulated between an extended position and a retracted position. The bottom is articulated to the lower end of the body between an extended position and a retracted position. When the container is filled and closed, the movement of the shoulder from the extended position into the retracted position causes the bottom to move from the retracted position into the extended position and vice-versa.
