Patent ID: 7490537

Claim:
A suppression apparatus for a suspected explosive device comprising a container which surrounds a cavity, wherein the container comprises a shell having an outer wall and an inner wall having a space therebetween, the outer wall having a surface of cylindrical shape which faces the interior of the shell and the inner wall having a surface which faces the interior of the shell, at least a portion of said surface of the inner wall which extends for either the entire height of the inner wall or substantially said entire height being of frusto-conical shape, wherein no part of the container covers either the bottom or the top of the cavity and wherein the slope of the surface portion of frusto-conical shape relative to the surface of cylindrical shape is such that when the container is filled with liquid the variation in thickness of the liquid renders the shot line through the liquid for an explosion from an explosive device to be about uniform when the explosive device is located in the cavity on a surface on which the container sits.
