    摘要： A method of forming a container and filling the container with a product. The method includes heat-set blow molding the container from a preform and hot-filling the container with the product such that the product occupies about 95% or more of a total interior volume of the container. A headspace volume is defined between a top fill line of the product and a brim of the container. The headspace volume is less than about 5% of the total interior volume of the container. The container is capped and allowed to cool. The container is configured to shrink during cooling such that the total interior volume decreases by about 0.5% to 1.5% during cooling. A base of the container is displaced after hot-filling and capping to reduce the total interior volume by less than about an additional 0.5% to 4%. The hot-filling, capping, cooling, and displacing of the base creates a pressure change within the container.

    摘要： 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.

    摘要： 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.

    摘要： 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.

    摘要： The present invention relates to a swivel arrangement for a carousel filler arrangement having a rotating tank (2) and a product pipe (4) for transporting product into the rotating tank. The swivel arrangement comprises a tank connecting part (6), a pipe connecting part (5), a first opening for receiving a gaseous media, a second opening for ejecting the gaseous media. A first channel is partly defined by a protruding portion of the pipe connecting part and an outer wall of the product pipe, and a second channel is partly defined by the protruding portion and a protruding portion of the tank connecting part. A gap is formed between the pipe connecting part and the protruding portion of the tank connecting part, the gap is located between the second channel and the second opening thereby forming a particle barrier whereby, in use, particles are hindered from entering the second channel by a flow of gaseous media from the first opening to the second opening via the first and second channels.
