Abstract:
A structure for facilitating the sectioning and reassembly of a vessel, the structure comprising:a circumferential channel formed integral with a wall of a hollow, contiguous, fluid containing vessel having opposed closed ends, the channel having an outer surface substantially parallel to the wall of the vessel and upper and lower circumferential transition surfaces, each transition surface being formed between the outer surface of the channel and the surface of the vessel; and,the outer diameter of the outer surface of the channel being inwardly radially offset from an inner surface of the vessel so as to be smaller than the inner diameter of an upper portion of the vessel, such that the outer surface of the channel may be received within the inner diameter of the vessel where the vessel has been sectioned into an upper portion and a base portion by removing the entire upper circumferential transition surface of the channel.
