Abstract : This invention relates to a tamper mass including particulate material held together by a binder in a self-contained supporting shape surrounding a concavity in a forward face containing an explosive, whereby upon detonation of the explosive, the tamper material provides initial and temporary confinement of detonation products to directing forces forward. After shock loading, the tamper material disintegrates into very fine particles, which individually contain very little energy in dispersion. Expendable perforators are used in many applications and generally include an explosive charge associated with a projectile for driving that projectile against a target. Such perforators are used in well boring and barrier penetration, as well as in bomb dearmament and disposal applications. It is a main object of the present invention to provide an explosive device for use as an expendable wall perforator which can be used notwithstanding the presence of personnel or property in the immediate proximity of the blast and without presenting a possibility of significant injury to either personnel or property. It is another object of the present invention to provide a blast containment device for use with a bomb dearming device which reduces the possibility of activating the bomb via an antidisturbance device associated with that bomb.
