Plastics amorce-cap ring or strip - has charge cups sealed by stoppers joined to each other

摘要

The plastics amorce-cap ring or strip has small cups at regular intervals and joined together, each with a paper-covered detonation charge on the bottom. Each cup (3) is sealed by a covering stopper (11) removable by hand. This fits positively inside the cup, forming a buffer zone (30) between it and the paper cover (6), and is also joined to the adjacent stopper, typically by a rib (35), these together forming a geometrical shape matching that of the ring or strip. The stopper can also have an annular edge (16) joined to the rib and by which it bears against the outer edge (17) of the cup. USE/ADVANTAGE - In a child's toy piston. Prevents accidental ignition by pressure or bending when in pocket.
