METHOD AND APPARATUS FOR INERTING THE HEAD SPACE OF A CONTAINER BY WAY OF CHUTE ATTACHMENT

摘要

A process to reduce oxygen in the head space of containers (17) includes introducing an inert gas into the container head space. This may be accomplished during a capping process. A cap chute attachment (52) may be incorporated to transfer gas from an inert gas source to a body portion (58) of the attachment. The gas may be directed into the body portion to pressurize the body portion. The inert gas may then flow through a gas exit end (62) to be directed toward one or both of a cap (15) and a container opening as the cap and container are brought into contact with each other. The inert gas displaces at least a portion of the oxygen from the head space.
