A method for detachably joining together a pair of barrel half sections to form a leak-proof barrel assembly suitable for storing and shipping fluids and other materials. The barrel is capable of being disassembled after initial use to minimize the space required for transporting it back to the original shipper and also to minimize the expense of reconditioning the barrel for reuse. The barrel comprises two nestable, frustrum-shaped half sections, each having a larger open end and a smaller end which is sealingly closed. The respective open ends of the two barrel halves each have respective outwardly-projecting flanges formed around their peripheries and are sealingly clamped together by placing a resilient gasket between the two flanges, pressing the half sections together utilizing a hydraulic or similarly powerful machine, placing a plurality of interlocking C-shaped clamps over the flanges around the periphery of the barrel and releasing the half sections, thereby forming a fully assembled container having a tight, leak-proof and tamper-resistant seal. 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.

A method for detachably joining a pair of barrel half sections together to form a leak-proof barrel assembly for storing and shipment of fluids and other materials, said barrel sections having a pair of projecting flanges extending peripherally around the open ends of said barrel sections and having a respective pair of oppositely facing lips formed peripherally around the edges thereof, said method comprising: (a) inserting a resilient gasket member between said flange pair as a pair of said barrel sections are positioned with their respective open ends opposed to each other and separated by the thickness of said gasket member; (b) pressing said opposed barrel sections together to compress said interposed gasket member between said flange pair utilizing mechanical press means for applying compressive force to said barrel sections; (c) while said pressure is maintained, inserting a plurality of C-shaped clamp members over said flange pair at spaced locations around the periphery thereof, said clamp members having their respective ends bent inwardly toward each other so as to mate with a portion of said oppositely facing lips when inserted on said flanged pair, (d) releasing said pressure applied to said opposed barrel sections by said press means, whereby said gasket member expansively urges said barrel sections apart, such that said outermost extremities of said oppositely facing lips are moved to bear respectively against the mating inner surfaces of said plurality of clamp members thereby locking said flange pair against respective ends of said C-shaped clamp members.
