ABSTRACT:
A disposable canister for use in an electric fogger includes a container to hold a fog-producing material which is constructed of a material capable of transferring heat from a heat source to the fog-producing material, an insert secured in the container to close the container and having a dome with a discharge port to allow the release of a fog, and a cap secured to the container and having an opening which overlies the discharge port of the insert to allow the release of a fog and one or more lugs which serve to activate an electric fogger when placed in the housing of the electric fogger. The cap of the disposable canister also includes outwardly extending rims which seat on the housing of the electric fogger and in conjunction with the lugs of the cap serve to lock the canister into the housing. The invention precludes the escape of any fog from the closure seal between the container and the cap into the housing of the electric fogger and provides for fully efficient use of the fog-producing material.
