Abstract
This relates to the modification of an existing type of closure which employs a fulcrum post about which a part of the closure functioning as a lever pivots while bearing on an axially facing surface of the fulcrum post so as to weaken the fulcrum post in a manner wherein, when a pry tool is used and bears against the fulcrum post in a radial direction, the fulcrum post will separate into bendable tabs both to hinder the prying operation and to give indication of tampering efforts.
