Patent ID: 7387073

Claim:
An explosive training device, comprising: a main body defining an internal cavity, and wherein a plurality of elongated channels extend through the main body and communicate with the internal cavity; an explosive charge received within the cavity of the main body, and which, when detonated, produces sound and visibly discernible light, and wherein a preponderance of the visibly discernible light, and sound produced by the detonation of the explosive charge escapes from the main body through the plurality of elongated channels; a removable primer head which releasably cooperates with one end of the main body of the explosive training device, wherein the removable primer head is first removed to facilitate the positioning of the explosive charge within the cavity of the main body, wherein the explosive charge is positioned adjacent to the end of the main body of the explosive training device which cooperates with the removable primer head, wherein the removable primer head defines a passageway which extends therethrough and which has opposite first and second ends, and wherein the passageway communicates with one end of the explosive charge; a single use primer assembly which is releasably mounted on the primer head and which is oriented in substantially occluding relation relative to the first end of the passageway, wherein the single use primer assembly has an outer housing which releasably mechanically cooperates with the primer head; and a primer charge borne by the outer housing of the single use primer assembly, which, when struck, causes the ignition of the explosive charge, wherein the outer housing of the primer assembly is rendered unusable by the ignition of the of the primer charge after a single use.
