Abstract
A fire extinguisher has a container filled with a fire extinguisher material. One wall of the container has tear-open segments that breach the container when opened and allow the fire extinguisher material to exit the container. An initiator forces open the tear-open segments. The initiator has a cup that is coupled to the container wall. The cup contains combustible material and is closed by a cap. The cap is bonded to the cup to form a strong initiator housing. A fuse exits the initiator to the outside of the container wall.
