A fire-resistant container having a full gasket at the interface between hinged top and bottom mating elements. The elements are insulated and are formed with matable labyrinthine edges. One of the edges is provided with a smooth, soft gasket disposed in a groove in the labyrinth which forms a seal against a corresponding rib in the opposing edge. The elements are joined along common sides by a hinge, the rotational axis of which is positioned in space relative to the gasket and rib such that, in closing of the container, the gasket engages the rib at all points substantially simultaneously. The hinged elements are secured by over-center latching means such that when the container is fully closed the rib exerts a small and substantially uniform force against the gasket to form a seal against fire and water. Upon being exposed to fire, the hinges and/or the latch may be destroyed without causing the seal between to be broken, thus maintaining the fire- and water- resistance of the container, the weight of the top element further compressing the gasket onto the rib and thereby enhancing the seal.

Boîtier résistant au feu (14) qui possède un joint d'étanchéité plein (62) à l'interface entre l'élément couvercle à charnière (12) et l'élément de fond (10) correspondant. Ces éléments (12,10) sont isolés et formés de bords d'appariement en forme de labyrinthes. Un des bords est pourvu d'un joint d'étanchéité (62) lisse et souple, placé dans une rainure du labyrinthe (54), qui produit l'étanchéité en butant contre une nervure correspondante ménagée (60) sur le bord opposé. Les deux éléments (12,10) sont joints le long de côtés communs par une charnière (18) dont l'axe de rotation (16) est placé dans l'espace par rapport au joint d'étanchéité (62) et à la nervure de manière (60) telle que lors de la fermeture du boîtier (14), le joint d'étanchéité (62) vient en contact avec la nervure (60) pratiquement simultanément sur tous les points. Les éléments reliés par charnière (12,10) sont fixés l'un à l'autre par un moyen de verrouillage (28,30) de sorte que lorsque le boîtier (14) est complètement fermé, la nervure (60) exerce une petite force essentiellement uniforme contre le joint d'étanchéité pour produire l'étanchéité (62) contre le feu et l'eau.
