ABSTRACT:
A novel initiator (blasting cap) for explosives is provided. The initiator, which may be electric or non-electric, comprises a principal tubular metal shell containing a base charge, a delay charge, a priming charge and an ignition means, wherein the base charge and priming charge are housed within a reduced diameter tubular metal shell, which reduced diameter shell is located within but separated from the principal shell by a void space. The construction results in a markedly improved resistance against shock initiation.
