ABSTRACT:
The present invention is directed to a container having a tear-away top. In general, the container comprises an outer substrate layer, an inner aseptic layer secured to the outer substrate layer, and a cut in the outer substrate layer. In order to preserve the product in the container, the cut is of a predetermined depth such that the cut does not puncture the inner aseptic layer. The cut, however, is sufficiently deep so that a predetermined portion of the top may be torn away from the container at the cut. The present invention also includes a method for manufacturing a container that has a tear-away top. The method generally includes the steps of providing an outer substrate layer, securing an inner aseptic layer to the outer substrate layer, making a cut of predetermined depth in the outer substrate layer such that the cut does not puncture the inner aseptic layer, and then forming a container. After the container has been formed, a predetermined portion of the top may be torn away from the container at the cut.
