Battery plate envelopes include a sheet of porous film material having a folded widthwise bottom edge and overlapped lateral edges to thereby form a pocket for receiving a battery plate therein. The overlapped lateral edges are joined to one another by a lengthwise extending series of discontinuous joining regions with adjacent ones of the discontinuous joining regions being separated by respective unsealed regions. These unsealed regions thereby establish respective lateral channels through which fluid (e.g., electrolyte employed in a wet storage battery) may pass to the interior pocket, and hence to the battery plate. The discontinuous joining regions are most preferably formed by passing the sheet material through the nip between opposed joining rings, each of which is provided with a series of triangularly-shaped teeth with smooth land areas formed between adjacent teeth series.

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.
