A reusable barrel 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.

In a barrel for storing and shipping fluids and other materials comprised of a pair of frustrum-shaped shell-like barrel sections, each having a closed end and an open end larger than said closed end and being interchangeably nestable one within the other when disassembled, said barrel sections each having mating means for sealingly and detachably joining said open ends together with the respective interiors of said two barrel sections facing one another, the improvement wherein said mating means comprises: a pair of projecting flanges each extending peripherally around the respective open ends of said barrel sections, a resilient gasket for inserting between said flange pair, a plurality of unitary C-shaped clamp members spaced at arbitrary locations along the periphery of said flange pair for holding said flange pair in non-contacting close proximity with said gasket compressed therebetween, and means associated with said flange pair and said clamp members for interlockingly engaging said flange pair and clamp members at said arbitrary locations along the periphery of said flange pair while permitting said clamp members to be detached from said flange pair at said arbitrary peripheral locations by the pressing of said barrel sections together momentarily to increase the compression of said resilient gasket, thereby freeing said flange pair from engagement with said clamp members.
