Media container and media protection apparatus

Abstract

The invention discloses a media container ( 4 ) adapted to protect a medium ( 10 ) having an opening ( 12 ) adapted to allow that a medium ( 10 ) is put into the media container ( 4 ) ; and a closure ( 8 ) by which the opening ( 12 ) may be closed; wherein the closure ( 8 ) is adapted such that in its opened state air from the media container ( 4 ) may be exhausted, that in its opened state protective gas may flow into the media container ( 4 ) and that in its closed state entering and/or exiting of a fluid from the media container ( 4 ) and/or into the media container ( 4 ) is prevented.

What is claimed is: 
     
         1 . A media container adapted to protect a medium having
 an opening adapted to allow that a medium is put into the media container; and   a closure by which the opening may be closed;   
       wherein the closure is adapted such that in its opened state air from the media container may be exhausted, that in its opened state protective gas may flow into the media container and that in its closed state entering and/or exiting of a fluid from the media container and/or into the media container is prevented. 
     
     
         2 . The media container according to  claim 1 , wherein the media container is a bag. 
     
     
         3 . The media container according to  claim 1 , wherein the protective gas comprises a weight proportion of approximately 50% to approximately 95%, preferably from approximately 60% to approximately 80%, most preferred from approximately 65% to approximately 75% of nitrogen. 
     
     
         4 . The media container according to  claim 1 , wherein the protective gas comprises a weight proportion from approximately 5% to approximately 50%, preferably from approximately 20% to approximately 40%, most preferred from approximately 25% to approximately 35% of carbon dioxide. 
     
     
         5 . The media container according to  claim 1 , wherein the protective gas comprises a volume proportion of approximately 50% to approximately 95%, preferably from approximately 60% to approximately 80%, most preferably from approximately 65% to approximately 75% of nitrogen. 
     
     
         6 . The media container according to  claim 1 , wherein the protective gas comprises a volume proportion of approximately 5% to approximately 50%, preferably from approximately 20% to approximately 40%, most preferred from approximately 25% to approximately 35% of carbon dioxide. 
     
     
         7 . The media container according to  claim 1 , wherein the closure is adapted to be sealed. 
     
     
         8 . The media container according to  claim 1 , wherein the closure is adapted to be welded. 
     
     
         9 . The media container according to  claim 1 , wherein the media container is fluid tight. 
     
     
         10 . The media container according to  claim 1 , wherein the media container is fluid tight up to an external pressure of approximately more than 2 bar, preferably more than approximately 5 bar, most preferably up to more than approximately 10 bar. 
     
     
         11 . The media container according to  claim 1 , wherein the medium is a film, a film reel with film, a sound carrier or a data carrier. 
     
     
         12 . A media protection apparatus, adapted to exhaust a media container according to  claim 1  and to fill the media container according to  claim 1  with protective gas, comprising
 a chamber adapted to accommodate the media container; 
 an evacuation opening in the chamber connected to a pump, wherein the pump is adapted to exhaust the chamber and the media container; 
 a protective gas opening in the chamber connected to a protective gas source, wherein the protective gas source is adapted to fill the media container with protective gas; and 
 a closure device adapted to close the closure of the media container. 
 
     
     
         13 . The media protecting apparatus according to  claim 12 , wherein the evacuation opening and the protective gas opening are formed integral. 
     
     
         14 . The media protecting device according to  claim 12 , comprising a conduit, arranged from the protective gas opening to the opening of the media container. 
     
     
         15 . The media protecting apparatus according to  claim 12 , wherein the closure device is adapted to close the closure of the media container by thermal energy. 
     
     
         16 . The media protecting apparatus according to  claim 12 , comprising a pressure compensation opening adapted to perform the pressure compensation for the chamber. 
     
     
         17 . The media protecting apparatus according to  claim 12 , wherein the pressure compensation opening is formed integral with the evacuation opening and the protective gas opening. 
     
     
         18 . The media protecting apparatus according to  claim 12 , wherein the chamber comprises a lid which may be opened and closed to put the media container into the chamber and/or to remove the same therefrom.
