Abstract: 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.
