Fitted-together covering lid and its attachment on food containers by means of wrapping, vacuum and cohesion

摘要

The fitted-together covering lid and its attachment on food containers by wrapping, vacuum and cohesion serves to close in particular packages for dairy products which have to be packaged so that they remain fresh for a long time and which should have a refittable closure in order to be able to use the contents in portions. Furthermore, for reasons of reducing the migration of pollutants into the contents of the package when the latter is closed, a novel method is used, called: "controlled diffusion using novel compounds". <IMAGE>
