Abstract

One embodiment of a reusable gas grenade canister includes an inner casing defining an interior space. An outer casing is spaced from the inner casing. A top plate is used to close a top end of the canister. Offset ports extend through the inner and outer casings. Fins extend outwardly from the outer casing for elevating the canister above a support surface. In use, a grenade is located and secured within the interior space. Upon ignition, material is expelled from the grenade into the interior space, then flows through the ports into the baffle space, then to a point exterior of the canister. In another embodiment, the canister comprises a body defining an interior space and includes a spike extending therefrom, the spike defining a flow path for gas to flow from the interior space to a point remote from the body.
