Abstract: A method and apparatus for venting a filled bottle closed by a stopper is disclosed. The venting is designed to equalize the pressure between the interior of the bottle and the atmosphere such that the stopper inserted into the filled bottle is not forced out of the bottle by excess pressure in the bottle. The venting may be accomplished by deforming the stopper in the bottle opening to form an air-outlet opening in the region sealed by the stopper and the bottle. The venting may be implemented by a squeezing device arranged on at least one side of the stopper, the squeezing device being active in a direction perpendicular to the central axis of the bottle opening.

Abstract: A capping apparatus, in particular for applying PRESON.TM. style caps to glass jars, comprising a chute with grooved sidewalls to allow free passage of the caps irrespective of tab orientation. At the chute outlet, stops depend from a bridge bar in order to engage the leading cap above its tab, again allowing caps to be presented in random orientation.

Abstract: This relates to a guide for guiding a closure cap onto a container neck finish in a machine for automatically applying closure caps to containers. Most particularly this relates to a guide assembly for closure caps which include a metal shell and a plastic overcap including a tamper indicating band which depends below the metal shell and wherein the closure cap cannot be supported by way of flanges or rails of a track in the normal manner in that the supporting part of the closure cap is subject to deformation and not true and round as in the case of metal closure caps. A lower portion of the conventional track has been replaced by a magnetic cap guide unit which forms an extension of the conventional track and which maintains the position of a closure cap after it has been initially engaged by the neck finish of a container so as to maintain the relationship of the closure cap relative to the container which permits the closure cap being seated square on to the neck finish for final automatic application.
