Abstract
A chemical oxygen generator using a chemical which generates oxygen by thermal reaction and an ignition device for the chemical is made by forming a continuous depression in a first plate, filling the plate depression with the chemical so as to completely fill the depression or to slightly overflow it, locating the ignition device in the depression adjacent one end thereof and covering the first plate with a second flat plate and pressing the two plates together to compact the chemical and deform the depression of the first plate. The plates are subsequently secured together with a gas-tight connection around the depression. The generator advantageously comprises a continuous serpentine-like depression in one plate and has a closed end located in the plate and an open end extending to the edge of the plate which may be sealed by a foil when the two plates are pressed together. The ignition device is located adjacent the open end and it may be activated to cause the production of the oxygen from the open end successively to the closed end.
