ABSTRACT:
To ensure the original state of the contents of a receptacle, the stopper comprises inwardly oriented blocking attachments on a surrounding tear-off sealing ring, with the blocking attachments gripping below an outwardly oriented annular projection of the receptacle. The blocking attachments are formed by lateral slides which cooperate with an inner contour sleeve. The sealing ring is respectively connected by a single tear-off web centrally between two adjacent blocking attachments to the upper circumferential wall. As a result, the finished stopper can be slid from the contour sleeve after cooling to 80.degree., the blocking attachments being smoothly guided on the guide surfaces of the contour sleeve. The sealing ring bulges elastically between two adjacent tear-off webs and subsequently assumes its original circular shape again.
