A carbon dioxide adsorbent container (710) for a diving breathing device has an external tube (720) having an end face constructed so as to form a sealed bottom, an internal tube (730) adapted to be inserted into the external tube through a bottom hole formed in the sealed bottom thereof and having an end face constructed so as to form a sealed bottom and a lid (750) adapted to be fitted into an opening in the external tube and having a fitting hole formed therein for receiving therein a leading end of the internal tube, the lid being adapted to be mounted on the external and internal tubes in a state in which it is prevented from coming off the tubes. The container (710) can be constituted by three members each having a simple construction and which are separately formed, and the respective members can easily be formed. In addition, it is possible to exchange carbon dioxide adsorbents only by mounting and dismounting this container on and from a breathing device.

Cette invention concerne un conteneur (710) adsorbant le dioxyde de carbone destiné à un appareil respiratoire de plongée, lequel conteneur comporte les éléments suivants: un tube externe (720) possédant une face d'extrémité conçue de manière à former un fond étanche; un tube interne (730) pouvant être inséré dans le tube externe à travers un trou pratiqué dans le fond étanche de ce dernier, et possédant une face d'extrémité conçu de manière à former un fond étanche; et, enfin, un couvercle (750) conçu pour s'adapter dans une ouverture du tube externe et comportant un trou d'adaptation qui va recevoir l'extrémité avant du tube interne. Ce couvercle est conçu de manière à être monté sur les tubes externe et interne dans une position telle qu'il ne peut se détacher de ces derniers. Le conteneur (710) peut être constitué de trois éléments ayant chacun une structure simple et formés séparément, les éléments respectifs pouvant être facilement formés. Il est également possible d'échanger les adsorbants de dioxyde de carbone simplement en montant ce conteneur sur un dispositif perméable et en le démontant de ce dernier.
