THREADED PLUG WITH AN EXPANDABLE GUARANTEE TAPE ON THREADING FOR THE FIRST TIME.

摘要

THE GUARANTEE SEAL (2) OF THE THREADED COVER (1) HAS A THEORETICAL POINT OF BREAKAGE (11) IN WHICH THE SEAL (3) IS OPENED IN ALL ITS HEIGHT. NEXT TO THE THEORETICAL POINT OF BREAKAGE, A DISCHARGE OPENING (12) IS PREPARED, PREFERABLY IN THE FORM OF A WINDOW, WHICH IMPROVES THE EXPANSIBILITY OF THE SEAL WHEN IT IS OPENED FOR THE FIRST TIME. THE THEORETICAL POINT OF BREAKAGE CONSISTS OF AT LEAST TWO FLANGES OF MATERIAL, THE LOWER ONE BEING DISPOSED ON THE BOTTOM EDGE OF THE COVER. OPENING THE LID FOR THE FIRST TIME, A FLOW OF FORCE IS OBTAINED IN THE SEAL THAT LEAVES THE DISCHARGE OPENING.
