Claims10
A chemiluminescent lighting device comprising a translucent container and contained therein:
- a. several inactive components of an active chemiluminescent mixture,
- b. barrier means separating said several components in several compartments within said container, said barrier means being breakable by impact with a striking means to combine said components,
- c. striking means for breaking said barrier means by impact therewith,
- d. a movable part that is movable within said container when said movable part is free and means restraining the free movement of said movable part within said container until the linear momentum of said movable part bearing against said restraining means exceeds a predetermined yield limit, whereupon said restraining means will yield and release said movable part for free movement,
- e. the said striking means, barrier means and movable part being located in relation to each other within said container so that when said movable part is released for free motion, within said tube said movable part will be impelled to bring together said barrier means and said striking means with impact sufficient to break said barrier means.
