| 摘要 | An enclosure for explosive material providing a safe, easily handled explosive booster or primer which can utilize liquid, slurry or solid explosive and which includes recesses to receive detonators. The explosive material is completely enclosed in a container, which illustratively might be an aluminum can including a sealed cover. A sleeve encircles the container. The sleeve and the container cooperate to form recesses for receiving detonators. One type of recess is open on only one end to retain a detonator such as a blasting cap. Another type of recess is open on two opposite ends to permit threading of a detonating cord on which the primer is suspended. The recesses might be formed by indentations in the container sidewall or by furrows in the sleeve. The sleeve can include explosive material to add to the explosive force of the detonator, thereby assuring actuation of the primer. | ||||||
| 权利要求 | 1. An enclosure for explosive material comprising: a cylindrical container including an enclosed lower end having a concave outer surface, a sidewall sealingly secured to said lower end and having a plurality of elongated recesses therein substantially equally spaced angularly about the sidewall, and a cover having a concave outer surface and adapted to be sealingly secured to said sidewall to form an enclosed, sealed container, and a sleeve adapted to fit over said lower end onto said sidewall, said sleeve and said sidewall recesses cooperating to receive at least one detonator; said lower end concave outer surface, said cover concave outer surface and said recesses providing a shaped charge effect upon explosion of explosive material within the container. 2. An enclosure as claimed in claim 1 in which at least one of said plurality of elongated recesses extends longitudinally on said enclosure from the junction of said lower end and said sidewall. 3. An enclosure as claimed in claim 2 in which at least one of said plurality of elongated recesses extends longitudinally on said enclosure the entire length of said sleeve. 4. An enclosure as claimed in claim 3 in which at least one of said plurality of elongated recesses extends longitudinally on said enclosure only part of the length of said sleeve. 5. An enclosure as claimed in claim 1 in which said container is an aluminum can. 6. An enclosure as claimed in claim 1 in which said sleeve is a fiber sleeve. 7. An enclosure as claimed in claim 6 in which said fiber sleeve is cardboard. 8. An enclosure as claimed in claim 1 in which said sleeve is a plastic sleeve. 9. An enclosure as claimed in claim 8 in which said sleeve includes an explosive plastic. 10. An enclosure as claimed in claim 1 in which said sleeve comprises a band of explosive plastic wrapped about the container and over the recesses. 11. An enclosure as claimed in claim 1 in which the sleeve includes at substantially the longitudinal center thereof a circular rib of an explosive material. |
