Pyrotechnic cassette

Abstract

A pyrotechnic cassette contains a pyrotechnic, it can be shipped separate from a primer, then placed in a rigid housing, together with the primer so as to form a pyrotechnic clay pigeon, or the like.

1 . A cassette adapted to fit into a substantially rigid housing forming a shooting target, the cassette containing a pyrotechnic and not containing ignition means. 
     
     
         2 . A cassette according to  claim 1  wherein the cassette is substantially disc shaped whereby it is adapted to fit inside an annular rim comprising part of the housing of the shooting target. 
     
     
         3 . A cassette according to  claim 2  further comprising a radially outwardly extending flange arranged to overlap one end of the annular rim of the housing of the shooting target. 
     
     
         4 . A pyrotechnic shooting target comprising a substantially rigid housing containing a cassette according to  claim 1 . 
     
     
         5 . A pyrotechnic shooting target according to  claim 4  wherein the housing further contains ignition means, separate from the cassette. 
     
     
         6 . A pyrotechnic shooting target according to  claim 5  wherein the rigid housing comprises a tube closed at least one end, the tube having a circular cross-section. 
     
     
         7 . A pyrotechnic shooting target according to  claim 6  wherein the cassette is spaced from the closed end of the tube by the ignition means. 
     
     
         8 . A pyrotechnic shooting target according to  claim 7  wherein the ignition means comprises a disc shaped primer. 
     
     
         9 . A pyrotechnic shooting target according to  claim 7  wherein the housing further comprises a lid shaped to fit around the tube and at least partially close the open end of the tube, the lid comprising an opening, whereby the target can be detonated by an inert projectile entering the housing through the opening, penetrating the cassette and impacting the ignition means causing the ignition means to ignite, thereby detonating the pyrotechnic. 
     
     
         10 . A kit of parts for a shooting target comprising a cassette according to  claim 1 , a rigid housing and ignition means. 
     
     
         11 . A cassette adapted to fit into a substantially rigid housing to form a shooting target, the cassette having an inner volume filled with
 (i) a pyrotechnic and optionally   (ii) one or more non-shock-sensitive components only.   
     
     
         12 . A cassette according to  claim 11  wherein the cassette is substantially disc shaped whereby it is adapted to fit inside an annular rim comprising part of the housing of the shooting target. 
     
     
         13 . A cassette according to  claim 12  further comprising a radially outwardly extending flange arranged to overlap one end of the annular rim of the housing of the shooting target. 
     
     
         14 . A pyrotechnic shooting target comprising a substantially rigid housing containing a cassette according to  claim 11 . 
     
     
         15 . A pyrotechnic shooting target according to  claim 14  wherein the housing further contains ignition means, separate from the cassette. 
     
     
         16 . A pyrotechnic shooting target according to  claim 15  wherein the rigid housing comprises a tube closed at least one end, the tube having a circular cross-section. 
     
     
         17 . A pyrotechnic shooting target according to  claim 16  wherein the cassette is spaced from the closed end of the tube by ignition means. 
     
     
         18 . A pyrotechnic shooting target according to  claim 17  wherein the ignition means comprises a disc shaped primer. 
     
     
         19 . A pyrotechnic shooting target according to  claim 17  wherein the housing further comprises a lid shaped to fit around the tube and at least partially close the open end of the tube, the lid comprising an opening, whereby the target can be detonated by an inert projectile entering the housing through the opening, penetrating the cassette and impacting the ignition means causing the ignition means to ignite, thereby detonating the pyrotechnic. 
     
     
         20 . A kit of parts for a shooting target comprising a cassette according to  claim 11 , a rigid housing and ignition means.
