Abstract
A sealing valve for container openings made from rubber elastic material and having a stopper member which can be introduced into the container opening up to a stopper collar projecting beyond the stopper member in a radial direction At least one control channel is formed on the stopper member and extends in the direction of the longitudinal axis of sealing valve from one end of the stopper member facing an inner region of the container A sealing lip is formed on the stopper collar and can seat in a sealing fashion on a container edge surrounding the container opening. The stopper collar has a control channel section transverse to the control channel of a stopper member which extends this control channel up to the sealing lip A reliable venting is guaranteed while simultaneously securing sealing to prevent the escape of battery liquids. Economical production with large yield is also facilitated.
