Bottle structure for crimp on-twist off caps
Abstract
Abstract A BOTTLE HAS ITS NECK PORTION PROVIDED WITH MULTIPLE THREAD STRUCTURE WHICH WILL RECEIVE AND HOLD A PRESSURE APPLIED CROWN OR CRIMP ON TYPE METAL CAP AND WHICH WILL ENABLE THE CAP TO BE MORE EASILY TWISTED OFF THAN PRIOR CONSTRUCTIONS. THE LOWER PART OF THE THREAD STRUCTURE TERMINATES IN AN OUTWARDLY PROJECTING CIRCUMFERENTIAL RING HAVING AN OUTER CYLINDRICAL SURFACE SUBSTANTIALLY PARALLEL TO THE AXIS OF THE NECK OF THE BOTTLE. THE OUTER DIAMETER OF THIS RING IS SUBSTANTIALLY EQUAL TO THE OUTER DIAMETER OF THE THREADS AND IS POSITIONED ON THE NECK SO THAT THE LOWER EDGE OF THE CAP CONTACTS THE MID PORTION OF THIS SURFACE. ALSO THE RIDGES OF THE MOLD PARTING LINES ON THE BOTTLE NECK ARE POSITIONED SO THAT EACH CROSSES ONE THREAD ONLY NEAR THE LOWER END OF THE THREAD.
