Abstract
An automatic stovetop fire suppressor providing a gradual release of a fire suppressing agent in a desired distribution pattern and method of gradual and spatial agent release are provided herein. A plastic cone shaped lid seals on the bottom of a can and forms a closed container. The closed container is filled with a fire suppressing agent. An initiator charge breaks a designed breaking point of a reduced horizontal cross sectional area when fuse activated. The bottom lid drops down exposing a radial opening. Fire suppressing agent flows out of the radial opening, suppressing a stovetop fire with minimal or no splashing of cooking oil. An initiator housing is affixed to a top wall of the can and serves as the welding point for securing the plastic lid. A travel limiting member attached to the bottom lid catches on a shoulder of the initiator housing to limit the radial opening height.
