Abstract
A pressure relief device of domed construction for venting an internally pressurized container. The pressure release device includes a coined pressure vent and is characterized by a relatively high venting pressure in combination with a failure pressure in the absence of venting which is higher than the intended venting pressure. The pressure relief device includes a sloped sidewall having an outer annular segment and a sloped annular intermediate segment. The sloped annular intermediate segment has a width dimension greater than the width dimension of the outer annular segment. A circular central plateau defines a flat dome top. The circular central plateau has a center point with an arc shaped coin line extending about an arc with the apex of the arc positioned at the center point of the circular central plateau.
