[ I claim:] [1.] Double-walled thermal container particularly for beverages and food liquids, comprising a first inner vessel (2) made of metallic material with an upper tapering portion (4) which forms a first opening (5) which can be closed by a detachable closure means (6), a second outer vessel (7), which is made of metallic material and has an upper tapering portion (9) which forms a second opening (10), said vessels being mutually and stably joined by a connecting assembly (11) which is arranged proximate to said openings (5, 10) so as to form an interspace (12) in which vacuum is produced, said connecting assembly (11) being constituted exclusively by parts (13, 18) made of nonmetallic material with low thermal conductivity so as to form a hermetic heat barrier between said inner and outer vessels (2, 7), characterized in that said parts (13, 18) of said connecting assembly (11) comprise a first annular part (13) having circumferential end edges (14, 15) which are in contact with the inner walls of the upper tapering portions (4, 9) of said vessels (2, 7), so as to form, with said walls, at least two circumferential pockets (16, 17) in which a sealing plastic resin is injected.
