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. 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.
Claims10
A thermoplastic preform configured to obtain by means of a blowing process a wide-mouth container suitable for use in a beverage dispenser,
- wherein the thermoplastic preform defines an axis X and comprises a neck and a body coaxial to axis X,
- wherein the neck has an inner cylindrical surface adapted to remain unchanged in said blowing process and having a total length Ltot along axis X, the body being adapted to be blown in said blowing process to take a shape of said wide-mouth container,
- said neck comprising
- a support ring;
- a neck finish extending from the support ring to an opening for pouring a beverage, and having a first axial length L1, which is part of said total length Ltot, and
- a cylindrical portion having a second axial length L2, which is part of said total length Ltot,
- wherein the support ring is arranged between the neck finish and the cylindrical portion,
- wherein the cylindrical portion is arranged between the body and the support ring,
- wherein said second axial length L2 is at least equal to said first axial length L1, and
- wherein said wide-mouth container has a volume comprised between 5 liters and 30 liters.
