Disk container

Abstract

This invention offers a plastic container for compact disk, whose back side is respectively connected with the bottom side and the cover side; and this container is formed through folding the three sides, that is the bottom, back and cover. A disk support base is designed in inner sides of the container bottom; the support base is composed with a button, a pair of small elastic sector area, and a pair of locking slip, etc. through the connection parts to form the elastic bridge; a small ring is designed on the outer circle of the supporting base on the container bottom. Compared with prior art, the rigid support base composed of large rigid sector area, three radial enforced tendons, small ring and locking slip replaces the structure of the old support base with smaller contact surface and weaker rigidity, hence making it more convenient to contain the disk, with excellent reliability, safety and endurance.

What is claimed is:  
     
         1 . A plastic container for compact disk, comprising cover ( 11 ), bottom ( 12 ) and back ( 13 ), said back ( 13 ) is respectively connected with the bottom ( 12 ) and the cover ( 11 ); and the container is formed through folding the three sides, that is the bottom ( 12 ), the back ( 13 ) and the cover ( 11 ); a disk support base ( 18 ) is designed in inner side of the bottom ( 12 ); said support base ( 18 ) is composed with the button ( 21 ), the small elastic sector area ( 15 ), and the locking slip ( 20 ), thus form the elastic bridge; characterized in that, a small ring ( 26 ) is designed at the outer circle of the support base ( 18 ) on the container bottom ( 12 ).  
     
     
         2 . A plastic container for compact disk as defined in  claim 1 , wherein the diameter of the small ring ( 26 ) is smaller than that of the central non-data area of the disk ( 25 ), said small ring ( 26 ) is vertical to the inner surface of the container bottom ( 12 ); the verticals height of the small ring ( 26 ) is the same as that of the arc shoulder ( 17 ) of the large sector area ( 16 ) on the container bottom ( 12 ).  
     
     
         3 . A plastic container for compact disk as defined in  claim 1 , wherein on the top of the core of said support base( 18 ), a ring-type core neck is composed in sections by a pair of rigid disk protection slip ( 19 ) and a pair of elastic looking slip ( 20 ); the diameter of the disk protection slip ( 19 ) is a bit larger than that of the locking slip ( 20 ); the height of the disk protection slip ( 19 ) is a bit higher than that of the locking slip ( 20 ) and the button ( 21 ).  
     
     
         4 . A plastic container for compact disk as defined in  claim 1  or  3 , wherein the vertical height of said small ring ( 26 ) is as same highness as that of the support shoulder ( 12 D) of the large outer circular gear-shape ring ( 12 A), the inner ring ( 12 C), and they also share one surface to form the disk support assembly.  
     
     
         5 . A plastic container for compact disk as defined in  claim 4 , wherein said container bottom ( 12 ) is designed with a large circular gear-shaped ring ( 12 A,  12 C,  12 D), to form an outer ring support base.  
     
     
         6 . A plastic container for compact disk as defined in  claim 4 , wherein said container bottom ( 12 ) is designed with a arc-shaped protrudent large circular and concave support base ( 12 D 1 ) to form the disk support assembly.  
     
     
         7 . A plastic container for compact disk as defined in  claim 1 , wherein the three radial lines ( 16 A,  16 B) from the sector core in the container bottom ( 12 ) is connected with the small ring ( 26 ) by segments through the inward radial enforced keel ( 27 ), hence forming the central rigid supporting parts, with the height of the radial enforced keel ( 27 ) a bit lower than that of the small ring ( 26 ).  
     
     
         8 . A plastic container for compact disk as defined in  claim 1 , wherein there is a protrudent paper-holding spring with long are ( 13 A) in the center of the container back ( 13 ), the length of the protrudent arc ( 13 A) is a bit shorter than that of the container back ( 13 ).
