(54) A multiple firing firework device with insert assembly and a multiple shot device


(57) A multiple firing firework device with insert assembly (10), comprising: a block (20), a plurality of the tubular apertures (40) being defined in the block (20) extends from top surface (21) to the surface corresponding to the top surface (21) i.e. bottom surface (22). The tubular apertures (40) have open top ends (41) on the top surface (21) and open bottom ends (42) on the bottom surface (22). The device also comprises a plurality of holders (60) for receiving pyrotechnic composition and each holder (60) is separately placed within a tubular aperture (40) of the block. By using a holder (60), the pyrotechnic composition is injected into the holder (60) beforehand instead of being in direct contact with the tubular aperture (40). The block (20) can then be completely dissolved in water for environmentally friendly disposal. In addition, there is a bottom plate (70) covering the bottom surface (22) of the device to avoid exposure of the ignition fuse (81). Safety is enhanced and the international safety regulations are met. This invention also comprises a multiple shot device.
