METHOD, MECHANISMS AND MEANS FOR THE PRESERVATION OF FOOD PRODUCTS, CHEMICALS, PAINT, COSMETICS ETC. WITHOUT THE NECESSITY OF PRESERVATIVE USE TO EXTEND SHELF LIVE

摘要

From a technical point of view, this invention belongs to the field of packaging, preservation and transportation goods. It solves the problem of the almost non-existent protection of the contents of a container or a package, after the latter has been opened and a part of the contents removed; this protection is achieved by removing the air and gases which spoil the contents. It consists of 3 main parts: The first part is the main 'container/utensil': It preserves the contents by keeping out the air that spoils it. This is achieved by adapting the form of the container/utensil to the volume of the contents each time. The second part consists of simple constructions of 'bags/flexible containers' and partitions which are combined with our containers/utensils or with any other already existing containers, providing the same result. The third part consists of 'plugs/valves' and 'valves/containers' which assure either the preservation or the safe ripening of the contents inside the main container/utensil. Further, our invention proposes methods of a more reasonable, safe and less-polluting construction of containers/utensils, as well as ways to transport and distribute them.
