Claim:
A non-pyrotechnic explosion device, comprising: a pressure chamber; an expandable rupturable membrane having an initial size and located between said pressure chamber and a pressure escape opening to the atmosphere; a pressure release device adapted to release pressure from said pressure chamber; an expulsion substance container arranged between said pressure chamber and said pressure escape opening to the atmosphere so that upon release of pressure from said pressure chamber said pressure forces an expulsion substance within the expulsion substance container against said expandable rupturable membrane to expand the expandable rupturable membrane beyond said initial size and further expand the expandable and rupturable membrane to the point of rupture thereby generating an audible report and discharging said expulsion substance; a coupler adapted to secure said expandable rupturable membrane to said expulsion substance container, said coupler comprising a shoulder; and wherein at least a portion of said shoulder is within said expulsion substance container and covered by a portion of said expandable rupturable membrane.
