摘要

The snap lock bottle is shaped so that they closing plug does not project beyond the greatest diameter of the bottle when the bottle is open, or only projects to an insignificant extend. There may be a niche in the bottle, in which the plug fits when the lock at the bottle neck is open, to keep the plug within the desired limits.
