Optical disc case structure

Abstract

An optical disc case structure comprises a bottom cover and a top cover assembled with each other. A conically pillared positioning member is placed on the bottom cover to position the optical disc by engaging the central hole thereof. A central protruding ring and a peripheral protruding ring are formed on the bottom cover where is placed the optical disc. A plurality of flanges further inwardly protrude from two sides of the top cover parallel to the top cover. Hence arranged, the flanges receive advertisement cards and further press on the optical disc once the top and bottom covers fold onto each other.

What is claimed is:  
     
         1 . An optical disc case structure comprising: 
 a case body, comprised of a first and a second part assembled with each other in a manner to fold and unfold with respect to each other;    a positioning member, conically pillared-shaped and protruding from a central portion of the first part in a manner to position an optical disc by engaging a central hole thereof; and    at least a pair of transversal flanges, the transversal flanges respectively placed at two peripheral sides of the second part in a manner to inwardly protrude so that an outer peripheral edge of the optical disc placed in the case body with the first and second parts folding onto each other is securely clamped via the transversal flanges.    
     
     
         2 . The case structure of  claim 1 , wherein the case body is formed via the assembly of a bottom cover and a top cover, and a central protruding ring and a peripheral protruding ring are formed on the bottom cover where is placed the positioning member, the central protruding ring being placed within a storage region of the optical disc and the peripheral protruding ring being placed outside the storage region of the optical disc.  
     
     
         3 . The case structure of  claim 2 , wherein a pair of arcuate projections are further placed outside the peripheral protruding ring, the height of the arcuate projections being approximately the height of the optical disc placed in the case body.  
     
     
         4 . The case structure of  claim 2 , wherein the bottom cover includes a bottom board, a front peripheral projection, a rear peripheral projection, a left peripheral projection, and a right peripheral projection; the front and rear peripheral projections respectively being composed of a pair of projecting elements that are spaced apart from each other via a take-up/put-in groove, the transversal flanges being disposed on at least one side of the take-up/put-in groove, the front and rear peripheral projections being respectively provided with an attachment protuberance, and further extending into a plurality of opposite connecting segments provided with a pivot axle; and the top cover including a top board, a left peripheral segment, a front peripheral segment, and a rear peripheral segment; a plurality of second connecting segments being respectively spaced apart from the front and rear peripheral segments via a respective spacing groove, the second connecting segments being respectively provided with a pivot hole to engage with the pivot axle to pivotably assemble the top cover with the bottom cover; an attachment groove being further respectively defined through the front an rear peripheral segments to engage with the attachment protuberances.  
     
     
         5 . The case structure of  claim 2 , wherein two sides of the left peripheral projection of the bottom cover are-respectively externally provided with an attachment protuberance and two sides of the left peripheral segment are respectively externally provided with a recess.  
     
     
         6 . The case structure of  claim 2 , wherein one transversal flange is provided at a location proximate to the left peripheral segment of the top cover to press on the optical disc.  
     
     
         7 . The case structure of  claim 2 , wherein a plurality of slots are defined in the front and rear peripheral projections of the bottom cover proximate to the take-up/put-in groove to engage with the transversal flanges.  
     
     
         8 . The case structure of  claim 2 , wherein a recessed portion is externally defined on the right peripheral projection of the bottom cover.  
     
     
         9 . The case structure of  claim 2 , wherein an inclined face is formed at the location of the take-up/put-in groove on the bottom cover.  
     
     
         10 . The case structure of  claim 1 , having a thickness smaller than 6 mm.
