Abstract
The present invention is directed to a method of using a laser to manufacture a container that has a tear-away spout. First, a flat card is formed by providing an outer substrate layer and then securing an inner aseptic layer to the outer substrate layer. After the flat card is formed, a cut of predetermined depth is made with a laser along a predetermined path in the outer substrate layer so that the cut does not puncture the inner aseptic layer. After the cut is made in the outer substrate layer, the flat card is folded to form a container that has a flap. The cut extends around the flap, and the flap has a tip. In order to form a spout, the tip is torn off at the cut.
