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.

1. A grenade device for providing a delayed bang upon coupling to a pressurized canister containing gas, said device comprising: an annular housing having first and second axial ends and an internal cylindrical bulkhead disposed therebetween, said bulkhead having choke flow-through orifice;a puncture awl extending axially outward from said bulkhead at said second axial end;a sleeve removably connecting to said housing at said first axial end;a diaphragm disposed between said sleeve and said housing to form an annular chamber between said diaphragm and said bulkhead;a cap inserting into said housing at said second axial end, said cap receiving the canister that faces said awl; anda base removably connecting to said housing at said second axial end, wherein in response to axial compression of the canister towards the device:said awl punctures the canister to release the gas,the gas flows through said choke orifice to pressurize said chamber, andsaid diaphragm ruptures upon exceeding a pressure threshold in said chamber. 2. The grenade device according to claim 1, wherein the canister is an 8-gram carbon dioxide cartridge. 3. The grenade device according to claim 1, wherein said sleeve, housing, said cap and said base are composed of stainless steel, and said diaphragm is composed of one of Mylar and aluminum. 4. The grenade device according to claim 1, wherein said diaphragm further includes at least one indentation for structural weakening. 5. The grenade device according to claim 4, wherein said diaphragm has a thickness of 0.013±0.001 inch, with said indentation having a depth of about 0.004 inch. 6. The grenade device according to claim 1, wherein said flow-through orifice includes a portion having a choke-flow area of 3×10−6 square inch. 7. The grenade device according to claim 1, further including a gasket between said bulkhead and said cap and an o-ring between said cap and the cartridge. 8. The grenade device according to claim 7, wherein said gasket and said o-ring are composed of rubber. 9. The grenade device according to claim 1, wherein said housing has an axial length of 1.05 inches and an outer diameter of Ø0.725 inch. 10. The grenade device according to claim 1, wherein said sleeve and said base each have a ⅝ inch hex rim. 11. The grenade device according to claim 1, wherein said sleeve, housing, said cap and said base are composed of stainless steel, and said diaphragm is composed of Mylar. 12. The grenade device according to claim 1, wherein said sleeve, housing, said cap and said base are composed of stainless steel, and said diaphragm is composed of aluminum.
