ABSTRACT:
Chemical oxygen generator cells, for insertion in push pin controlled dispensers and having a conventional steel can housing containing a chlorate candle and a water activated ignition material to start burning of the candle, are provided with a water containing fracturable sealed glass ampoule, capsule, or vial in contact with the ignition material and are protected against inadvertent fracture by an overlying shock cap with a spring diaphragm wall adapted to be depressed by the push pin of the dispenser to crush the glass and release the water to the ignition material. The diaphragm wall acts with a snap action from its overlying protecting position when its center is deflected by the dispenser pin to crush the glass thereby insuring the release of the water to the ignition material only when the dispenser pin is depressed and at all other times protecting the glass against fracture as when the can is dropped or impacted or even dented.
