ABSTRACT:
It is the purpose of this utility process invention to allow a means to recycle the common aluminum beverage can. This is accomplished with the addition of a scribe or scribes to the circumference of the can. The depth and position of the scribe acting as a pre-conditioner, weakening the can a specific amount in a specific location, there by allowing the desired or eventually desired separation at that specific location by secondary means if required. The scribe allows the can to be separated into cylindrical sections having a very smooth and accurate cut edge. These sections may be containers similar to a cup shape, sections with both ends of the can removed and sections with the can top removed. These scribes may or may not meet. Depending upon the eventual use, the sections may remain united. These scribes may be added any time during the can's life span either before opening or after opening and emptying the original contents. The scribe or scribes may be added at any location on the side wall height extending from beneath the can top lip to the bottom and on top near the edge. Said scribe may be added externally or internally to the can, internally allowable as the can is modified.
