A plastic container comprises an upper portion including a finish defining an opening into the container, a lower portion including a base defining a standing surface, a sidewall extending between the upper portion and the lower portion, the sidewall defining a longitudinal axis, and at least one substantially transversely-oriented pressure panel located in the lower portion. The pressure panel is movable between an outwardly-inclined position and an inwardly-inclined position to compensate for a change of pressure inside the container. The standing surface defines a standing plane, and the entire pressure panel is located between the standing plane and the upper portion of the container when the pressure panel is in the outwardly-inclined position.

Method for processing hot-filled plastic containers are provided. In some embodiments, the method may include hot-filling a plastic container, sealing the container, and conveying the sealed container, each with an inner annular wall and a push-up portion in a first position. In some embodiments, the method may further include creating a vacuum pressure in the hot-filled and sealed container and repositioning or inverting the push-up portion from the first position to a second position under the vacuum pressure.

Plastic container that is to be filled with a hot product includes a threaded neck portion, a base portion including a standing surface and a moveable element, and a body portion including a dome portion, first and second label stop portions, a supplemental vacuum panel and a sidewall relatively free of structural geometry that surrounds an interior of the body portion. During cooling, the hot product is contracted so as to create an induced vacuum. The supplemental vacuum panel is configured and operative to remove a first portion of an induced vacuum, and the moveable element is configured and operative to move from a first position to a second position to remove a second portion of the vacuum, wherein the first portion of the vacuum and the second portion of the vacuum constitute substantially the entire vacuum.

In one embodiment, a method of processing a plastic container having a longitudinal axis is disclosed. The method includes: blow-molding a plastic container having an upper portion including a finish, a sidewall, a lower portion including a base defining a standing surface, and a substantially transversely-oriented pressure panel having an inner annular wall and a central push-up portion located in the base, wherein a base mold portion is displaced longitudinally with respect to first and second side mold portions to form the pressure panel set above the standing surface; introducing heated liquid contents into the plastic container with the pressure panel located in an outwardly-inclined position entirely between the standing surface and the upper portion; capping the plastic container; and, moving the pressure panel to an inwardly-inclined position entirely between the standing surface and the upper portion.

A filling-element assembly for both pressurized and open-jet filling of containers includes a filling element having a filling-element housing, a liquid valve, a return-gas channel, and a seal. The housing has a fixed first segment, a vertically movable second segment, and an extendable segment between them to surrounds the valve housing in a fluid-tight manner. A return-gas channel extends along the filling-element axis between the valve housing and the filling-element housing. In a raised position of the second segment, the seal contacts the valve housing along a circumferential contact area and seals the filling-element discharge opening thereby forming a fluid-tight closure for the return-gas channel.
