Disclosed is a non-fragmenting explosive device for perforating a target and injecting a material through the perforation to disrupt structure behind the target. The device is particularly adapted to safely disarm unexploded explosive devices such as bombs without detonation of the bomb. The device includes an outer covering of explosive material for explosively confining the disruptive material to a well defined shape for total injection into the target.

An explosive device for perforating the wall of a target and ejecting a liquid through the perforation for disrupting structure behind the target wall, comprising: a hollow case formed of plastic material having two opposing ends, an inner surface and an outer surface, said case adapted to be substantially consumed by burning and be free of fragmentation when the device is detonated; a shaped charge liner formed of plastic material in fluid-tight attachment with said case inner surface adjacent one end thereof and facing in an outward direction for placement toward a target to be perforated; a first explosive contained within said case at the second end thereof; a shockwave transmitting liquid material located in the case between the shaped charge liner and the first explosive, whereby, upon detonation, the first explosive creates high pressure gases the shockwave of which is transmitted through the liquid material for collapsing the shaped charge liner and causing it to perforate the target wall and cause the liquid material to follow through the perforation; and a second explosive in the form of a sheet completely covering the outer surface of the case and completely covering the second end of the case including the first explosive charge; whereby, upon simultaneous detonation of the first and second explosives, forces exerted inwardly by the second explosive balance the outward forces of the first explosive to prevent their radial expansion and expansion toward second end to confine its forces in the direction of the shaped charge liner, thereby confining said liquid material to a well defined shape and causing substantially all of said material to pass through the wall perforation.
