Abstract

A non-returnable beverage package is provided where upon opening of the package the volume of the package can be increased. The increase is provided by a cover coordinated with a cup which together constitute the package. This package is particularly suitable for milk shakes. It allows a mixing of the contents of the package before use in an enlarged volume and in a volume adapted to provide turbulent flow to the liquid contained. The package provides for a safe packing of the filled in beverage from the time of filling-in to the time of opening the package.
