Abstract: The unitary clip for a tray and lid of a waffle pack includes a lower expanse with two upwardly extending hooks. The hooks include upper oblique surfaces which extend upwardly and outwardly. The upper oblique surfaces are immediately upwardly adjacent from inverted ledges which engage complementary portions of the lid of the waffle pack. The lower expanse is bowed so as to form a central apex which engages the lower planar portion of the waffle pack. The clip is engaged and disengaged from the waffle pack by a simple up and down motion.

Abstract: A thin film bridge initiator is mounted on a header for use in a detonator where a primer is activated by heat from the thin film. The initiator includes a substrate which carries a pair of metallic beam-type leads connected by a thin film bridge which activates the adjacent primer. The beam-type leads are affixed (welded) to a pair of electrical pins which are on adjacent sides of a slot in the header. The entire structure is very cost effective, reliable and provides fast functioning and safety. In addition, a process of manufacturing several bridge initiators at one time on a single wafer is provided.
