ABSTRACT:
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.
