Cover case of recording medium for rental or sale use

Abstract

To make it possible to keep a recording medium for rental or sale use accommodated in a cover case under a stable state without shaking and to take it out without applying excessive force, a receiving table having a support surface on which a center portion of the disk-like recording medium is put is so formed at a base center of a main body as to protrude from a base. Two slit grooves are formed at the center of the support surface of the receiving table with a predetermined gap between them. Engagement protuberances protrude from distal ends of arms formed between both slit grooves in such a fashion as to protrude from the arms and to form a pair. An outer peripheral edge extends from the base surface with the receiving table as the center and the engagement protuberances fit into a center hole of the disk. The outer periphery of the disk is put on and supported by the outer peripheral edge.

What is claimed is:  
     
         1 . A cover case of a recording medium for rental or sale use, for accommodating therein a disk-like recording medium such as a CD, comprising: 
 a main body;    a cover connected to the main body through a connection portion;    a receiving table protruding from a center of a base of said main body and having a support surface on which a center portion of said disk-like recording medium is put;    slit grooves formed on the support surface of said receiving table;    engagement protuberances formed at and extending from distal ends of arms formed in such a fashion as to be interposed by said slit grooves; and    an outer peripheral edge having notches formed at places thereof with said receiving table as its center and extending from the base.    
     
     
         2 . A cover case of a recording medium for rental or sale use according to  claim 1 , wherein two slit grooves are formed at a center of the support surface of said receiving table with a predetermined gap between them.  
     
     
         3 . A cover case of a recording medium for rental or sale use according to  claim 2 , wherein fall-off prevention pawls engaging with the outer periphery of said disk-like recording medium are formed by cutting off said outer peripheral edge in such a fashion as to erect from said base surface.  
     
     
         4 . A cover case of a recording medium for rental or sale use according to  claim 1 , wherein it further comprises engagement pawls independently undergoing deflection and provided to said arms in such a fashion as to form pairs with said engagement protuberances.
