Abstract
A shaped charge capsule includes an open-ended casing and a ring. The casing is adapted to house an explosive, and the casing includes a shoulder to receive a cap to close the casing. A rim of the casing at least partially surrounds the shoulder. The ring is adapted to be placed radially inside the rim and crimped with the rim to secure the cap to the casing. The ring is adapted to melt above an approximate predetermined temperature to release the cap from the casing. The cap may alternatively be secured to the casing by an adhesive that decomposes above the approximate predetermined temperature threshold.
