Data medium package and a method for producing a data medium package

Abstract

A method for producing the data medium package ( 1 ) which can be used integrally and is composed of a single material, and a data medium package ( 1 ) in the form of a box produced using this method—for holding essentially round data media having a central opening, in particular compact disks (CD), video disks (VD) or mini disks (MD)—having a cover ( 2 ) and a holding part ( 3 ) is disclosed. The holding part ( 3 ) may comprise a holding element ( 4 ), a supporting element ( 24 ), a stabilization element ( 19 ) and a case element ( 12 ), which are or can all be produced from a basic material of the same generic type and composed of natural fibres. The holding element ( 4 ) comprises a raised area ( 6 ) which supports a data medium ( 18 ) in a central region where there are no data which can be called up, and a holding pin ( 7 ) which is designed such that it essentially fills the central opening of a data medium ( 18 ) which has been inserted and prevents it at least from carrying out a movement parallel to the base of a depression ( 5 ), so that the regions of the data medium where the data which can be called up are located are protected against damage from scratching, chafing and impact. The holding element is produced by press forming of the basic material having a water content of about 7 to 20% using a forming tool.

         6 . Method according to  claim 1  wherein said process of press forming is performed by more than one step wherein each of said steps is performed applying an increasing forming pressure for each step.  
     
     
         7 . Method according to  claim 6  wherein said process of press forming is performed by applying at least 3 forming steps, wherein during the first step the holding pin is drawn.  
     
     
         8 . Method according to  claim 1 , wherein at least the holding element, the supporting element, the stabilization element or the case element is processed by stamping.  
     
     
         9 . Method according to  claim 1 , wherein at least the stabilization element or the case element is produced by scoring and folding.  
     
     
         10 . Method according to  claim 1 , wherein the holding element, the supporting element, the stabilization element and/or the case element are adhesively bonded to one another.  
     
     
         11 . Method according to  claim 1 , wherein renewable raw materials are used as the basic material for producing the data medium package.  
     
     
         12 . Data medium package in the form of a box composed of a single material—for accommodating at least one essentially round data medium having a central opening, in particular a compact disk (CD), video disk (VD) or mini disk (MD)—having a cover and a holding part, wherein the holding part comprises a holding element with a raised area for supporting a data medium in the central area, where there are no data which can be called up, a stabilization element for filling cavities and a case element for holding and encasing all the other elements of the data medium package and of the data medium to be packed, in which case all the elements are assembled from basic material of the same generic type and composed of natural fibres wherein the holding element is produced by press forming of said basic material having a water content of about 7 to 20% using a forming tool.  
     
     
         13 . Data medium package according to  claim 12 , wherein said holding element comprises a holding pin for centring a data medium, and a supporting element for forming or supporting the holding pin, in which case the holding pin is designed such that it essentially fills the central opening of a data medium that has been inserted and prevents said medium at least from carrying out any movement parallel to the base of a depression.  
     
     
         14 . Data medium package according to  claim 13 , wherein said the supporting element is designed as the holding pin and extends through an opening in the holding element.
