A BEVERAGE CONTAINER ASSEMBLY FOR HOLDING A BEVERAGE

摘要

The present invention relates to a beverage container assembly for holding a beverage. The assembly comprises an outer container defining a body portion and a cylindrical neck portion. The cylindrical neck portion defines a rim located opposite the body portion. The beverage container assembly further comprises an inner bag positioned within the outer container and defining a pressure space inside the inner bag and a beverage space between the inner bag and the outer container. The beverage space is filled by beverage and the inner bag initially defines a folded state. By subjecting the inner bag to a pressure fluid it is capable of expanding into an unfolded state in which the pressure space at least partially substitutes the beverage space. Both the inner bag and the neck portion are sealed off by a cap at a location between the rim and the body portion.
