Packaging device for substantially platelike data carriers and method for manufacturing same

Abstract

A packaging device for substantially platelike data carriers, comprising two cover parts, connected with a back part, while fixing means are provided for the data carriers, which fixing means are arranged such that at least two data carriers can be positioned therein next to each other, displaced relative to each other so as not to entirely overlap each other.

1 . A packaging device for substantially platelike data carriers, comprising two cover parts, connected with a back part, while fixing means are provided for the data carriers, which fixing means are so arranged that at least two data carriers can be positioned therein next to each other, displaced relative to each other so as not to entirely overlap each other.  
     
     
         2 . A packaging device according to  claim 1 , wherein the fixing means are arranged at least substantially on the back part.  
     
     
         3 . A packaging device according to  claim 1  or  2 , wherein the fixing means comprise at least two pairs of fingers which extend from the back part, while each pair of fingers is designed for receiving between them an edge portion of a data carrier, while the pairs of fingers are so arranged as to be displaced relative to each other in the longitudinal direction of the back part.  
     
     
         4 . A packaging device according to any one of the preceding claims, wherein the fixing means are designed for receiving at least three data carriers, arranged so as to be displaced relative to each other.  
     
     
         5 . A packaging device according to any one of the preceding claims, wherein at least one of the cover parts is provided with positioning means for locking the data carriers in the fixing means at least when the packaging device is closed.  
     
     
         6 . A packaging device according to  claim 5 , wherein the positioning means are provided adjacent a longitudinal edge of at least one cover part, opposite the back part.  
     
     
         7 . A packaging device according to any one of the preceding claims, wherein at least one of the cover parts is provided, remote from the back part, with supporting means for supporting the data carriers when the packaging device is closed.  
     
     
         8 . A packaging device according to  claim 7 , wherein the supporting means have different heights from the respective cover part.  
     
     
         9 . A packaging device according to any one of the preceding claims, wherein the fixing means are substantially rod-shaped, in particular cylinder-shaped or frustoconical.  
     
     
         10 . A packaging device according to any one of the preceding claims, wherein the pairs of fixing means are so designed that the data carriers, in the position received therebetween, stand at a relatively small distance from the back part, while a stiffening ridge extends over the longitudinal direction of the back part.  
     
     
         11 . A packaging device according to any one of the preceding claims, wherein the packaging device is injection molded in one part.  
     
     
         12 . A packaging device according to any one of the preceding claims, wherein the packaging device, at least the cover parts thereof, are manufactured from a transparent material.  
     
     
         13 . A packaging device according to any one of the preceding claims, wherein the packaging device, at least the cover parts thereof, are manufactured from polypropylene or a polypropylene-containing plastic.  
     
     
         14 . A packaging device according to  claim 13 , wherein the polypropylene or polypropylene-containing plastic is polymerized with metallocene.  
     
     
         15 . A packaging device according to  claim 14 , wherein the plastic substantially consists of a mixture of a polypropylene homopolymer and a polypropylene copolymer, polymerized with a metallocene as catalyst.  
     
     
         16 . A packaging device according to any one of claims  12 - 15 , wherein at least one of the cover parts has a transparency of more than 93.5%, in particular 95.5% or more, preferably 97% or more.  
     
     
         17 . A packaging device according to any one of the preceding claims, wherein the cover parts are substantially flat on the sides facing inwards in closed condition.  
     
     
         18 . A packaging device according to any one of the preceding claims, wherein decoration has been provided through in-mold labeling technique.  
     
     
         19 . A method for manufacturing a package, wherein a plastic is formed by polymerizing a mixture of at least propylene and at least one other monomer with a metallocene as catalyst to form a metocene-polypropylene copolymer, whereafter the plastic is injection molded to form the desired package.
