Abstract

A packaging container has an upper top member and a lower bottom member, and at least one cooperating locking means. Each locking means comprises an upstanding post and a cooperating opening or recess formed in extending lips of the top and bottom members. A weakened fault zone is formed in the immediate region of each post, or of each cooperating opening or recess, and circumscribes the same. The packaging container is locked in its closed position after it has been filled, by crimping the end of each post in an axial direction so as to mechanically deform the post. Any attempt to disengage a crimped post will result in failure of the respective weakened fault zone and may be construed as tampering, and thus the damaged material of the package in the region of the failed fault zone is evidence of tampering.
