  • Opening and closing a container
    Patent number: 6796244
    Abstract: A ballistic projectile (10) includes a body (12) defining a hollow, open-ended payload cavity (22) covered by means of a cover portion (26) fitting as a spigot into a socket (12.1) defined by the body (12). Peripheral seats in the form of grooves (32), (34) are provided in register in peripheral slide surfaces of respectively the cover portion (26) and the body (12) forming the spigot-socket combination. A peripheral, discontinuous shear ring (36) is received within the respective grooves (32), (34) to bridge the interface and thus to lock the cover portion to the body. Pressure selectively generated in the payload cavity shears the ring (36) to allow parting of the cover portion to expose the payload cavity.
