Stoppers; refilling, preventing.-The stopper D is placed in the conical screw cap or collar E, and the latter is then screwed on the neck and affixed in position by means of cement. The collar has a projecting rim A' which fits in a corresponding groove in the neck. The stopper is forced into the bottle in opening the latter and, as it cannot be again raised to its closing position, it affords an indication as to whether the bottle has been opened.
