Safety closure for bottles and containers

摘要

The stamping of the material of the closure cap or the screw connection to about 9/10 of the top surface is intended to prevent tearing off but to allow tearing open of the lid before the glass container can burst under excess pressure and thus lead to a great risk of injury. The problem can be solved in a simple manner during manufacture of the screw connection or cap by stamping the material to a minimum of its normal thickness. The use of the safety closure as a screw connection, crown cap or closure is primarily used in the beverage industry.
