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 capping machine (10) and method for installing a cap (12) having a threaded portion onto a container (14) having a threaded portion, the threaded portion of the cap corresponding to the threaded portion of the container, the capping machine having a rotatable turret (20) and a rotatable cap chuck (16) which grips the cap and positions the cap on the container. The cap chuck is rotated by a spindle (22) driven by a servo motor (24) at adjustable and reversible rotational velocities independent of the rotational velocity of the turret. The number of rotations of the cap is determined by monitoring the number of rotations of the servo motor compared to the number of rotations of the turret and is transmitted to a spindle drive control(70). The torque imparted to the cap is monitored by a torque monitor (50) and is transmitted to the spindle drive control. The rotational velocity of the cap is adjustable in response to the compared monitored number of rotations and monitored torque. The capped container is released from the cap chuck after a selected number of rotations of the cap onto the container has been made. Caps applied outside a selected range of monitored torques and number of rotations are tracked and rejected.

A chuck (10) has a jaw bell (20), a lower bell portion (22) surrounding a plurality of jaws (40) and a hub (28) surrounding an upper portion of a jaw stem (60). A second portion of the jaw stem extends beyond a jaw bell hub (28) and is surrounded by a compressed jaw stem spring (76). The jaw stem spring is retained between a bell hub collar (34) and a jaw stem collar (70). The force of the jaw stem spring holds the jaw bell around the jaws, holding the jaws in a closed position. A stripper (80) has an upper end (82) carried within the jaw stem. A stripper spring (90) located above the upper end of the stripper is compressed and surrounded by the jaw stem. The lower end of the stripper has a disk (84) with a frusto-conical cross-section in slidable contact with the jaws.
