Container

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 the push-up portion from the first position to a second position under a mechanical force.

Method of handling a plastic container having a moveable base

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.

One embodiment of the present invention provides a system for processing containers. The system may include an apparatus for processing sealed plastic containers having a first headspace pressure. The apparatus may include: an open entry port or tunnel for continuously receiving containers; a sanitizer configured to sanitize outside surfaces of the received containers; a perforator configured to perforate or open a cap or seal of the containers within the apparatus; a sealer configured to seal the perforation or opening formed in the cap or seal of the containers; an open exit port or tunnel for continuously exiting the processed containers; and a conveyor system configured to transport or convey the containers. The system may further include a production line including a filler for filling empty blow-moulded containers with a heated liquid to pasteurize inside surfaces of the containers and a capper for sealing the filled blow moulded containers.

System for processing containers

Plastic container having a movable base

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.

Plastic container having a deep-set invertible base and related methods

A hot-fill PET container or bottle () filling with a liquid at an elevated temperature has a side wall () extending to a lower portion including a pressure panel () and a base () in its unfolded or pre-fill position. The panel () is transversely oriented and has a decoupling or hinge structure or element (), an initiator portion () and control portion () of a steeply angled inverting conical section between 30 and 45 degrees. The control portion enables the inversion of the panel () into the container () to compensate for vacuum or reduced pressure induced within the container as the liquid cools down. The base () can also have a plurality of reinforcing ribs ().

Container structure for removal of vacuum pressure

One embodiment of the present invention provides a method for processing plastic containers within an open aseptic converter chamber comprising a sanitized environment, a supply line, a sanitizer device, a perforator device, a sealing device, and a conveyer. During operation, the method includes: providing and filling a container with heated or heatable liquid including water; sealing the container with a seal or cap; cooling the container to create a first headspace pressure; enclosing the container within the chamber; creating an opening in the seal or cap within a sanitized environment of the perforator device; increasing the first headspace pressure to a second headspace pressure by introduction of a sanitized fluid; resealing the container within a sanitized environment of the sealing device; and, transporting or conveying the sealed container away from the chamber.

Hybrid method for processing containers

To modify the headspace in a container to remove vacuum pressure, a container has a seal or cap which may provide a temporary opening into the container which is sealable under compression to provide a controlled raising of the internal pressure as the heated contents of the container cools. A sealing chamber () may enable the introduction of a fluid into the headspace () to force the fluid level () lower. Other methods and apparatus are described.

Headspace modification method for removal of vacuum pressure and apparatus therefor

A blow molded plastic container is provided. The container has a body section having a substantially non-circular cross-sectional shape, the body section having an enclosed bottom portion that forms a bottom end of the container and substantially flat side portions extending upwardly from the bottom end; a finish defining an opening; and a dome extending from the body section to the finish. The dome includes at least one stiffening structure formed by an inwardly indented, vertically extending groove.

Rectangular container having a stiffening groove

A sealing and pressure dosing apparatus, and container filling method, including a capping machine () which receives containers (). Closures () are applied to the containers () immediately following the raising of pressure within the containers () by a pressure dosing system in a pressure sealing chamber (). Preferably a cooling system is integrated with the capping machine.
