Abstract

A package unit includes, in combination, a generally elongated shaped food item for consumption when the package is open, and a container which surrounds and seals the elongated shaped food item. The container includes a first tear line formed adjacent to one end of the container along a plane generally perpendicular to the axis of the elongated shaped food item for opening the container. A second tear line is formed along the plane generally parallel to the food item for exposing one end of the food item after the container has been open by removing a portion of the container along the first tear line. The second tear line extends at one end from the center portion of the first tear line toward the other end of the container and terminates at its other end in a central section of the container. Third and fourth tear lines each extend at opposed angles from the other end of the container and are joined together adjacent the other end of the second tear line.
