Abstract: A container and locking device for gas tightly locking a container for gas masks and breathing equipment containing moisture-sensitive filter mass, including a first container shell and a second container shell, each container shell having outwardly projecting circumferential edges at front surfaces, the first container shell and the second container shell abutting at the front surfaces. A strap surrounding the projecting circumferential edges to clamp the circumferential edges. A sealing member connecting the first container shell and the second container shell, the sealing member being inserted into grooves located at the front surfaces of the first container shell and the second container shell.

Abstract: A gas mask and breathing equipment air cleaning cartridge (1) with a carbon dioxide-binding chemical packing (4) and an insert (3). The insert has legs (6) arranged in a radiate pattern perpendicularly to the direction of flow. The legs (6) have a flexibility that compensates for differences in the filling ratios of the strands (5) of chemical and have an identical bent zigzag-shaped designs to provide good heat distribution in the circumferential direction and good resistance to vibrations and shocks.
