Abstract: A metal reusable barrel for storing and shipping fluids. The barrel is capable of being disassembled after initial use to minimize the space required for transporting the barrel back to the original shipper and also minimize the expense of reconditioning the barrel for reuse. The barrel comprises two barrel halves, each in the shape of a frustum with the larger end open and the smaller end sealingly closed by a circular plate. The open ends of the two barrel halves are sealingly clamped together to form a fully assembled, leak-proof barrel. When the barrel is empty it may be disassembled by detaching the two barrel halves from one another and nesting one inside the other for shipment back to the producer. In their disassembled condition the barrel halves can be easily cleaned and reconditioned because of the accessibility of their interior surfaces, after which they may be reassembled and reused.
