An integral low profile cell closure equipped with resealable safety valve means is disclosed having a cover, an apertured seat centrally enclosed within the cover, elongated resilient sealing means bearing on the seat, and a top cover bearing on the resilient means at a position outwardly spaced from the bearing positions formed with the seat. The cover and top cover are secured together at their respective marginal portions, effected by crimping the cover around the top cover, for instance, to provide a large cross-sectional escape path for gas released through the valve.
