Abstract
Within a cylindrical container or canister, closed at both ends by a respective cover member, there is located a flare or illuminating rocket. For firing the flare rocket it is sufficient to remove the rear cover and by pulling at a tear line there is activated a tear ignition device or fuze. The ignited flare rocket then pierces the front cover member. This front cover member preferably possesses a ring-shaped or annular reference fracture location which subdivides the cover member into a disk-shaped inner portion and a ring-shaped outer portion.
