A THERMOPLASTIC PREFORM FOR A WIDE-MOUTH CONTAINER.

摘要

An innovative neck (301) configuration is suggested in order to reduce the weight of a large container for beverage dispenser. The neck (301) comprises a neck finish (303) which extends in length (Ltot) starting from the wide mouth (302) of the container to an annular support ring (305) and a smooth surface cylindrical portion (306) which joins the annular support ring (305) to the body (309) of the container. For functional reasons, the total length (Ltot) of the innovative neck (301) remains the same as the usual traditional necks for this type of container, but due to the short length (Ltot) of the neck finish (303) and said cylindrical portion (306), the weight is reduced.
