ABSTRACT:
A method of making a safety vent in an hermetically sealed electro-chemical container device and a novel container portion including such safety vent comprising a unique series of steps including printing a preselected area of the container portion with a masking resist pattern having an uncovered planar area of preselected geometric configuration corresponding to a safety vent area for the container portion and etching the uncovered area to a preselected uniform material thickness to provide a safety vent in the container portion capable of withstanding a preselected pressure before profound and instantaneous rupture.
