Abstract

An optical disc case structure comprises bottom and top covers. A holding member for holding the optical disc is further placed within the case. The holding member is defined from at least an arcuate positioning tongue and an arcuate holding tongue. The arcuate positioning tongue has an inner surface thereof upwardly extending in inclined and taper manners while an outer surface thereof upwardly bends into a rounded profile. The arcuate holding tongue is connected to the bottom board via a connection in which a U-shaped clearance is defined by cutting through the bottom board so that a bottom face of the arcuate holding tongue is inclined. The arcuate holding tongue is integrally inclined outwardly meanwhile projecting toward the received disc. Thereby, the arcuate holding tongue can resiliently deviate to hold the optical disc.

Claims

1. An optical disc case comprising:

2. The case structure of claim 1, wherein two end portions of the left peripheral segment are respectively provided with a protuberance corresponding to a hole respectively provided at two end portions of the left peripheral projection.

3. The case structure of claim 1, wherein a holder bar is placed proximate to the left peripheral segment and/or a pair of short holder bars are placed proximate to the right peripheral segment.

4. The case structure of claim 1, wherein two short arcuate projections are placed oppositely with respect to the take-up/put-in groove, thereby being spaced apart from each other via a distance slightly greater than the width of a rectangular data optical support.

5. The case structure of claim 1, wherein each projecting element of the front and rear peripheral projections includes a recessed portion.

6. The case structure of claim 1, wherein an opening groove is defined on an outer surface of the right peripheral projection.

7. The case structure of claim 1, wherein an inclined face is defined proximate to the take-up/put-in groove of the bottom board.

8. The case structure of claim 1, wherein the bottom cover and the top cover are made of an opaque material.

9. The case structure of claim 1, wherein at least a transversal flange is respectively defined on an inner surface of the front and rear peripheral segments.

10. The case structure of claim 1, having a thickness smaller than 5 mm.
