ABSTRACT:
Venting system for an electric storage battery having an electrolyte drainage aperture at the low point in the sloping floor of an electrolyte trapping chamber and including an integrally molded shielding enclosure depending beneath the aperture. The enclosure is defined in part by a flap-like closure wall which is resiliently rooted to the underside of the floor and depends therefrom at such an angle as to underlie the aperture. The resiliently rooted wall permits the wall to be molded beneath the aperture yet deflect out of the way and return (i.e., due to plastic memory) when the mold core is withdrawn.
