Abstract (en)
[origin: US4333578A] A bottle cap is provided with a circular inner peripheral relief member that is in opposition to a mating groove in the neck of the bottle. An annular collar is positioned beneath the relief member and is spaced from the neck of the bottle. A bottle opener is used to crack the annular collar to thereby indicate that the cap has been removed.
