Abstract
A sealing cap for a container provided with a safety valve is described, this sealing cap consisting of a bottom part which can be screwed onto the container neck and firmly locked there and of a top part which can be screwed onto the bottom part. The bottom part serves to seal absolutely the container neck provided with the safety valve, by compressing, in a moisture-tight manner, the joint between the edge of the container neck and a molding forming the valve support. The bottom part, fixed in position by retaining tabs and detent lugs, and capable of being loosened only by force, remains fixedly connected to the container during use. The top part can be unscrewed.
