Paperboard carton for frozen foodstuffs

Abstract

A carbon formed from a unitary blank of paperboard and being of rectangular parallelepiped shape. The carton is particularly adapted to contain a food product, such as a frozen juice concentrate or a frozen mass of other food product. The invention relates to a top closure construction which enables the consumer to remove the top closure so that the carton contents, particularly if in the form at a frozen brick, can easily be removed. Further, after such removal, the remainder of the carton can function as a measuring container for pouring any liquids therein which are to be added to the food product. These functions are achieved by the provision frangible lines, such as perforated tear lines, straight across the carton sidewalls, contiguous to the top of the carton sidewalls. The carton top closure is provided with a pull tab or a fin having a free end which can be manually grasped by the consumer. Upon pulling the pull tab or fin, the perforated lines are ruptured and the container top closure can be displaced from the remainder of the container and thus permit sliding removal of the frozen food product. The interior surface of the carton is provided with a frangible barrier layer, such as a conventional polyethylene or other extruded layer, to cover the perforations of the perforated lines and thus prevent leakage and also contamination of the carton contents through the perforations.
