ABSTRACT:
An electrolytic capacitor comprising an open ended casing, said casing having an inner wall with means defining a tapered surface channel; and a resilient seal member compressibly supported by the tapered surface in the channel to form a hermetic seal for the open end of the casing. Venting means can be provided by forming the channel with a gradually varying depth such that excess gas pressure can be vented by causing the seal to be tipped out of the channel at the shallowest point of the channel.
