A container suitable for use in the transportation of hazardous materials, for example radiolabelled material, has a base cup member (12) which is closed by a threated lid (13). Within the cup member (12) a liner (17) is provided whithin an inner cavity (16). The liner (17) is suspended from an end flange(18) which is in engagement with the upper face of the rim of the cup member (12). The liner (17) has an annular shoulder (23) spaced from the end flange (18). The shoulder (23) is arranged so that it engages and thereby seals with the head (26) of a closure element (25). The closure element (25) also includes means (31) to enable it to be removed from the liner (17). The container is usually mounted within a two-part inner casing (10a, 10b) which in turn is positioned within an outer casing (11a, 11b). With the container described hazardous materials even in liquid form may be stored and transported safely as desired whithout the need for bulky packaging.

Conteneur adapté pour transporter des matières dangereuses, par example une matière marquée aux isotopes, comprenant un élément cupuliforme basal (12) qui est fermé par un couvercle fileté (13). A l'intérieur de l'élément cupuliforme (12) un garnissage (17) est prévu dans une cavité interne (16). Ce garnissage (17) est suspendu depuis une bride d'extrémité (18) qui est en contact avec laface supérieure du rebord de l'élément cupuliforme (12). Ledit garnissage (17) présente un épaulement annulaire (23) espacé de la bride d'extrémité (18). L'épaulement (23) est configuré de sorte qu'il bloque et ferme hermétiquement la partie supérieure (26) d'un élément de fermeture (25).

Ce conteneur est habituellement monté dans un caisson interne (10a, 10b) constitué de deux parties qui, à son tour, est placé dans un caisson externe (11a, 11b). A l'aide de ce conteneur on peut stocker et transporter sans danger des matièresdangereuses, même si elles sont liquides, en fonction des besoinssans devoir utiliser pour cela un emballage encombrant.
