The apparatus comprises a spindle assembly, having a longitudinal spindle axis, that is connected to a frame for movement of the spindle assembly along the spindle axis. The spindle assembly comprises a cap gripper that is configured to hold a cap centered over the open end of a container so that axes through the cap, the open end of the container and the spindle assembly generally coincide. To place a cap on the container, the spindle is released for free movement along the spindle axis.

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. The jaw stem spring exerts more force downward on the jaw bell than the stripper spring exerts downward on the stripper to hold the jaw bell around the jaws and the jaws closed. Moving the jaw bell upward further compresses the jaw stem spring so that the force of the stripper spring moves the stripper downward, thereby moving the jaws downwardly and outwardly from the jaw bell to open the jaws.

A plastic screw cap has a threaded top portion and tabs of varying heights disposed around an inner circumference of a lower sleeve-portion. These tabs clasp a land disposed on a container neck to restrain the sleeve portion on the neck when the cap is unscrewed. A threaded top portion mates with threads on the container above the land. A sealing liner and diffusion barrier disposed at the bottle opening, together with a crush-resistant cap structure, prevent wine leakage and control oxygen ingress. Typically, the plastic cap is threaded onto the container neck, forming a tamper-evident seal. When unscrewed, the plastic-cap top moves up the container threads, exerting a pull on the sleeve portion, which is restrained due to the closure tabs acting on the land. Between the closure tabs and the threaded top is a breakaway line, which tears due to the removal forces. This tear evidences tampering.

A closure device with a fluid chamber containing an additive. The additive can be introduced and mixed into a liquid on the container by the closure device. The closure device includes a cap member having a fluid chamber and a housing having a plug member. The cap member is provided with a primary engagement member which engages with a corresponding primary engagement member provided on the housing to allow the cap member to be lifted relative to the housing from a closed position in which the plug member closes an aperture in the fluid chamber to an open position in which the plug member is at least partially withdrawn from the aperture, thereby allowing the additive to pass from the fluid chamber to the liquid in the bottle. The closure device enables mixing of the additive and liquid in the bottle without opening the closure.
