Protective structure of disc packaging

Abstract

A “protective structure of disc packaging” of the invention is composed of an upper lid, a lower lid and a casing that are formed on the top and the bottom sides and the perimeters of a pile of discs, and a heat-shrinkable film covers the protective body and said discs together to retaining the disc quality during the disc packaging and delivery processes. The characteristic of the invention lies in: the upper lid and the lower lid are respectively composed of at least two interlaced disc-shaped plates, which possess wavy buffer portions that are made of corrugated paper or plastic corrugated sheet. When the upper and the lower disc-shaped plates are disposed, the undulating buffer portions of the disc-shaped plates are vertically stacked up, in addition, the sizes of the disc-shaped plates are larger than the sizes of the discs and the casing being shaped as a roll.

1 . A “protective structure of disc packaging” primarily comprising an upper lid, a lower lids and a casing that are formed by the top and the bottom sides and the perimeters of a pile of discs; a heat-shrinkable film covers the protective body and said discs together for removing the use of packing boxes or cases; the characteristic lies in: the upper lid and the lower lid are respectively composed of at least two interlaced disc-shaped plates, possessing wavy buffer portions thereof; when the upper and the lower disc-shaped plates are disposed, the undulating buffer portions of the disc-shaped plates are vertically stacked up, in addition, the sizes of the disc-shaped plates are larger than the sizes of the discs; the casing is shaped like a roll.  
   
   
       2 . The “protective structure of disc packaging” of  claim 1 , wherein the protective structure is made of corrugated paper.  
   
   
       3 . The “protective structure of disc packaging” of  claim 1 , wherein the protective structure is made of plastic corrugated sheet.  
   
   
       4 . The “protective structure of disc packaging” of  claim 1 , wherein the upper lid has the circle centers thereof set round holes corresponding to the positions of those discs.  
   
   
       5 . The “protective structure of disc packaging” of  claim 1 , wherein the lower lid has the circle centers thereof set round holes corresponding to the positions of those discs.  
   
   
       6 . The “protective structure of disc packaging” of  claim 1 , wherein the protective structure enables the surface thereof to be printed some advertising scripts.  
   
   
       7 . The “protective structure of disc packaging” of  claim 1 , wherein the protective structure is able to be printed on the surface of advertising patterns thereof.
