Selon l'invention, un contenant cryogénique isolé du vide comprend sensiblement deux récipients (1, 2) respectivement à parois multiples et se fermant réciproquement par leur ouverture. Une premier contenant à parois multiples (1) est inséré dans le deuxième contenant (2) de telle façon que le premier contenant (1) ferme le deuxième contenant (2). Un moyen d'arrêt et/ou distanceur tient à distance la paroi interne d'un contenant (2) de la paroi externe (12) de l'autre contenant (1), de telle façon que, lorsque le contenant cryogénique est fermé, les surfaces interne (5) et externe (12) respectives des deux contenants (1, 2) à paroi double ne se touchent pas. L'atmosphère interne du premier et du deuxième contenant (1, 2) est évacuée jusqu'à l'obtention d'un vide très poussé.
