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.

A container has a longitudinal axis, and comprises an upper portion including an opening into the container, a sidewall portion extending from the upper portion to a lower portion, the lower portion including a base, and a pressure panel located in the lower portion substantially transversely to the longitudinal axis, the pressure panel being movable substantially along the longitudinal axis between an initial position and an inverted position to compensate for a change of pressure induced within the container. The pressure panel comprises an initiator portion and a control portion, the initiator portion adapted to move in response to the change of pressure prior to the control portion.
摘要:
A plastic container comprises an upper portion including a finish adapted to receive a closure, a lower portion including a base, and a sidewall extending between the upper portion and the lower portion. The upper portion, the lower portion, and the sidewall define an interior volume for storing liquid contents. The plastic container further comprises a pressure panel located on the container and moveable between an initial position and an activated position. The pressure panel is located in the initial position prior to filling the container, and is moved to the activated position after filling and sealing the container. Moving the pressure panel from the initial position to the activated position reduces the internal volume of the container and creates a positive pressure inside the container. The positive pressure reinforces the sidewall. A method of processing a container is also disclosed.

A container for containing a heated liquid and having a longitudinal axis. The container comprises at least one substantially vertically folding vacuum panel portion disposed substantially transversely relative to the longitudinal axis, the vacuum panel portion adapted to compensate for vacuum pressure changes within the container caused by heating or cooling of a liquid contained within the container. The vacuum panel portion comprises an initiator portion and a control portion, with at least a portion of the control portion being more steeply inclined relative to the longitudinal axis than at least a portion of the initiator portion. The initiator portion causes the control portion to flex inwardly into the container. The pressure panel inverts vertically in a direction substantially parallel to the longitudinal axis.

A resealable closure system that includes a neck having a finish and a closure. The system includes mechanisms for sealing the container and maintaining the container in a closed position, which may be the same. The system can also include a means for preventing the closure from detaching from the container. The finish has an end that includes a post, an opening and a retaining ring, a recess defined by the retaining ring, and a shoulder. The closure slides onto the neck and has a sleeve that is about the same outside size as the neck. The sleeve has a stop on its interior surface. The top part of the closure has a receptacle to receive the post on the finish.

A container forming assembly and method includes receiving a parison within a cavity of a mold, enclosing the parison within the mold having a wall with a recess, inflating the parison in the mold to form a blow molded container where the blow molded container has a sidewall, a movable region formed at the recess, and a hinge circumscribing an interface between the sidewall and the movable region, and moving or repositioning the movable region toward an interior of the blow molded container about the hinge before filling. The movable region can form a deep-set grip. Further, multiple movable regions can be provided, each of which may form respective deep-set grips. The container shape can be symmetrical or asymmetrical.
