Abstract
A vent cap for enclosing filler openings of a storage battery comprises a base terminating at a ring 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 relieved 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 relieved 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. The cover has a downwardly depending central stem member having depending therefrom three baffle means each spaced one from the other and projecting outwardly perpendicularly from the stem member, with the uppermost baffle means projecting outwardly a greater distance than that of the other two and having a top surface which slopes downwardly from said stem member. Each baffle means has a diameter of from about 95% to about 97% of the interior diameter of the base wherein each respective baffle means resides.
