protection device for hermetically sealed tamper proof and method for making a sealing frangible closure

摘要

The container closure connects a first plastic part (21) to a second plastic part (12) which has a substantially flat surface. The first plastic part has an outer wall which runs substantially perpendicular to the flat surface and whose one end produces a connection to the second plastic part at the flat surface thereof. This connection is formed by a thin, frangible section (24). Formed in the second plastic part (12) on the outside of the connection and adjacent thereto is a depression (23) whose inner wall is formed by the thin, frangible section (24). IMAGE
