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. A lock connected to the strap ends for holding the strap ends, the lock being pivotable for pivoting movement around at least one hinge located at one of the first container shell and the second container shell, the lock including a tumbler participating in the pivoting movement and a transmission member participating in the pivoting movement, the tumbler moving from a closed position engaging the strap ends to a release position for releasing the strap ends upon the pivoting movement, the transmission member acting on the first container shell and the second container shell to move the first container shell and the second container shell relative to increase a distance between the front surfaces.

Locking device for the container of a gas mask and breathing equipment

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.
