A tamper indicating closure has a hermetically sealed membrane which prevents contamination. The membrane is held within a closure cap for easy application to a container neck prior to being heat welded to the container. A disc secured to the membrane together with a pull ring serves to sever the membrane and open the sealed container. A lid functions to cover the membrane and disc until the seal is to be broken and thereafter to close the container when not in use. The only way to gain access to the contents, i.e. to the interior of the container, is by tearing the membrane. The means for tearing the membrane substantially covers the membrane except for a very thin edge portion thereof adjacent the spout of the container. This insures that tearing for the purpose of opening will substantially completely remove the membrane and also insures that access to the membrane for tampering purposes is very difficult.
