ABSTRACT:
A thermoplastic container, particularly a bottle, has a one-piece container top unitarily formed with the container body and a container neck and enclosing a stopper of elastomeric material, particularly rubber. To prevent contact between the container contents and the stopper, a mounting and separating element is provided between the stopper and the container. The mounting element has tubular axially extending plug and retaining portions and has one edge which can be welded to the container and a radially projecting, thin weld ring.
