Abstract

A sealing valve 10 for container openings made from rubber elastic material and having a stopper member 11 which can be introduced into the container opening up to a stopper collar 12 projecting beyond the stopper member 11 in a radial direction 26. At least one control channel 16 is formed on the stopper member 11 and extends in the direction of the longitudinal axis 24 of sealing valve 10 from one end of the stopper member 11 facing an inner region of the container 20. A sealing lip 15 is formed on the stopper collar 11 and can seat in a sealing fashion on a container edge 25 surrounding the container opening. The stopper collar 12 has a control channel section 29 transverse to the control channel 16 of a stopper member 11 which extends this control channel 16 up to the sealing lip 15. A reliable venting is guaranteed while simultaneously securing sealing to prevent the escape of battery liquids. Economical production with large yield is also facilitated.
