This container includes an insulating body, a door made of an insulating material, and mechanism for locking the door in the closed position. A multi-component container having a volume adaptable on demand, less heavy and less expensive, whilst having good resistance to wear and to blows. This body is formed by stacking body elements which are made of an insulating material and which are each generally U-shaped, the ends of the wings thereof defining the access opening, the elements being inserted between end elements which, having the same U-shaped cross-section as these but being closed at one side by a bottom, are reinforced by independent metal frames which exert thereon a compressive strength which is produced by metal clamping rods. These extend between the two frames and pass through the body elements and the end elements via holes.
