Abstract
A vent cap for enclosing filler openings of a storage battery comprises a base terminating at a rim including a generally U-shaped channel and a cover, the periphery of which engages the channel of the base. The periphery of the cover is provided with an essentially planar face having a chamfered termination and a plurality of circumferentially spaced, secant-shaped portions formed therein. The inner and outer faces of the cover are provided with reliefed portions adjacent to the secant-shaped portions formed in the cover's periphery. The secant-shaped portions formed in the periphery of the cover and the reliefed portions formed in the inner and outer faces of the cover cooperate with the U-shaped channel to develop a series of apertures between the base and cover.
