  • Patent number: 6552660
    Abstract: A pyrotechnic smoke generator which is flexible and may be molded or extruded into a thin layer is provided by embedding smoke composition particles in an elastomer, preferably silicone. The smoke composition particles have a preferred particle size range which will pass through a number 18 sieve and not through a number 40 sieve. The smoke generator may be utilized with flexible circuitry in a currency alarm pack to provide a money pack with an alarm which provides the flexibility and feel of a money pack without an alarm pack. The smoke composition particles when used in a money pack would contain a red dye and may contain tear gas. The smoke generator may be provided with a film covering, such as polyurethane, or embedded reinforcing fibers for additional strength. A film coating may also provide additional sealing capability for sealing the smoke composition particles and tear gas within the elastomer.
