摘要
The assembly has a removable spacing ring (3) that bears against a shoulder around a neck. The ring and a cap (2) are formed integrally in one unit and joined by material bridges. The ring is provided with an internal diameter greater than an external diameter of cap to enable the cap to slide through the ring after breakage of material bridges. The ring is provided with the internal stops (33) adapted to limit the movement of cap through the ring to keep a punch (22) spaced from lid when the cap is screwed onto neck and butted against the ring.
