Title: Storage battery vent cap

Abstract

A vent cap is described for enclosing a filler opening of a storage battery, comprising: (a) a generally cylindrical base portion adapted at a first end thereof to enter into and to engage the filler opening and, terminating at the other end thereof in a rim having a ring including and inwardly disposed, essentially U-shaped cavity, the first end further having an inwardly extending closure member which defines an aperture which is less in diameter than the diameter at the rim, with the cylinder being unrestricted as it extends from the first end toward the rim; and (b) a cover portion having a periphery engaging the channel of the base portion and a downwardly depending central stem member having depending therefrom three baffle means each having substantially planar lower surface and projecting outwardly essentially perpendicularly from the stem member and each having a diameter of from about 95% to about 97% of the interior diameter of the base portion wherein each respective baffle means resides, (c) wherein the periphery of the cover portion incorporates an essentially planar face having a chamfered termination and a plurality of circumferentially spaced shaped portions formed therein, and (d) wherein the shaped portions cooperate withmore » the channel to develop a plurality of apertures disposed about the interface between the base portion and the cover portion.« less
