摘要

Use of inflatable bulbs or bags as flexible bulk fillers in packaging units where the bulbs bags can be inflated with air, compressed air or gas, using a counter-pressure so that the packaging unit in the closed state is protected against slipping, dropping, or tilting. An independent claim is included for an opening used as a valve or safety valve.
