Abstract
A grenade device produces a delayed bang upon coupling to a pressurized canister containing gas. The device includes an annular housing, an awl, a sleeve, a diaphragm, a base and a cap. The housing has first and second axial ends and an internal bulkhead disposed therebetween with a choke flow-through orifice. The awl extends axially outward from the bulkhead. The sleeve connects to the housing at the first axial end. The diaphragm is disposed between the sleeve and the housing to form an annular chamber. The cap inserts into the housing at the second axial end and receives the canister facing the awl. The base connects to the housing at the second axial end. When the canister is compressed towards the device the awl punctures the canister to release the gas, which flows through the choke orifice to pressurize the chamber, and the diaphragm ruptures upon exceeding a pressure threshold.
