Explosive device

An explosive device comprising:

• a sealed enclosure having a pair of separate chambers and at least one common wall therebetween, non-explosive ingredients of a fluid explosive material being separately disposed in the respective chambers, said common wall having an opening therein for providing communication between the pair of chambers, a closure member blocking the opening in said common wall to initially prevent communication between the pair of chambers, means biasing said closure member to a position clear of said opening, removable latching means retaining said closure member in blocking relation to the opening, said closure member being movable by said biasing means to clear said opening for providing communication between the pair of chambers to affect mixing of the ingredients forming the explosive material in response to the removal of said latching means, igniter means carried by the enclosure for detonating the explosive material, and pressure-responsive means responsive to increase in pressure of the fluid explosive material for actuating the igniter means.

An explosive device comprising a sealed enclosure defining a cavity having a flexible wall, a fluid explosive material disposed within said cavity, a striker within said enclosure, pyrotechnic igniter material disposed within said enclosure in spaced relation to said striker, bias means biasing said striker towards the pyrotechnic igniter material, retaining means retaining said striker in a retracted position spaced from the pyrotechnic igniter material, and pressure-operable means responsive to an increase in pressure of said explosive material for releasing said striker from said retaining means, whereby upon an increase in pressure on said flexible wall the pressure condition of the explosive material increases within said cavity to operate on said pressure-operable means thereby releasing said striker from said retaining means to permit said bias means to urge said striker into contact with said pyrotechnic igniter material to ignite said pyrotechnic material for detonating the explosive material.
