ABSTRACT:
A completely separable seal for a container opening having a throat with a restriction therein including a casing, an explosive charge in the casing, a projectile tethered to the casing, the projectile including a thin completely separable peripheral diaphragm for closing the container throat having upper and lower surfaces, the charge mounted against the upper surface, means on the seal for engaging the throat restriction when the charge has been fired to subsequently limit downward thrust of the projectile into the container after separation of the diaphragm from the container throat to thus permit the projectile to reverse direction as the upward explosive forces overcome the downward explosive forces to thus propel the casing and tethered projectile from the container throat thus opening the container. The invention includes the complete closure for the container as well as the method of opening the rupturable sealed aperture.
