Abstract (en)
The paillet (22) has a cylindrical shape central zone forming a projectile, and an annular disk shape maintain zone (38) that is formed outside of the central zone, where the zones are formed in a single part. A cylindrical shape break-off intermediate zone is extended towards front between an interior edge of the maintain zone and a peripheral edge of the projectile. A radial thickness of the intermediate zone is lower than a radial thickness of a cylindrical wall of the central zone. Sealed units e.g. metal-asbestos gasket, are provided at a periphery of the central zone. An independent claim is also included for a detonator comprising a body.
