In this embodiment, the optical disc protection cover 20 may further include a plurality of first ribs 24 disposed on the protection cover body 21 and interposed between the first side wall 22 and the second side wall 23 . Wherein, the first rib 24 is used to strengthen the strength of the protective cover body 21 .

Please refer to FIG. 5 again. In this embodiment, the first rib 24 extends from the first side wall 22 to the second side wall 23 .

Please refer to FIG. 6 , which is a schematic cross-sectional view of the optical disc protection cover in a preferred embodiment of the present invention along the B-B' section in FIG. 5 . The height of the first rib 24 is less than the first side wall 22, the height of the first rib 24 can be less than or equal to the height of the second side wall 23, in this embodiment, the height of the first rib 24 is less than the second side wall 23 .

Please refer to FIG. 5 again. In this embodiment, the optical disc protection cover 20 may further include a third side wall 25 .

In FIG. 5 , the third side wall 25 is disposed around the through hole 211 . The heights of the second side wall 23 and the third side wall 25 are almost the same. In this embodiment, the optical disc protection cover 20 further includes a second rib 26 extending from the third side wall 25 to the first side wall 22, and the height of the second rib 26 is equal to that of the third side wall. 25 in height. In addition, the second protruding rib 26 has an enlarged portion 261 for strengthening the strength of the second protruding rib 26 .

Of course, please refer to FIG. 7 , which is another perspective view of the optical disc protection cover in a preferred embodiment of the present invention. The optical disc protection cover 20 may only have the second ribs 26 instead of the first ribs 24 . In this way, without the obstruction of the first ribs 24 , the printed patterns on the optical disc will not be blocked.

In addition, in this embodiment, the number of first convex ribs 24 is not limited to eight, and it can also be shown in FIG. The sheet protection cover 20 has seven first ribs 24 radially extending from the first side wall 22 to the second side wall 23 . The number of the first ribs 24 can be adjusted according to actual manufacturing requirements.

Furthermore, the first protruding rib 24 is between the first side wall 22 and the second side wall 23, and its setting method can have the following changes:

Please refer to FIG. 9 , which is another schematic top view of the optical disc protection cover in a preferred embodiment of the present invention. The first rib 24 extends from the first sidewall 22 to the second sidewall 23 , but does not touch the second sidewall 23 .

Moreover, as shown in FIG. 10 , it is another schematic top view of the optical disc protection cover of the preferred embodiment of the present invention. The first rib 24 is extended from the first side wall 22 to the second side wall 23, and can be arranged in a star shape; or as shown in Figure 11, it is a protective cover for an optical disc in a preferred embodiment of the present invention. Another schematic top view of FIG. 2 , which extends from the tangential direction of the first side wall 22 to the second side wall 23 .

Please refer to FIG. 6 and FIG. 12 again. FIG. 12 is a schematic diagram of a protective cover for optical discs in a preferred embodiment of the present invention for packaging multiple optical discs. In this embodiment, the side of the third side wall 25 facing the through hole 211 can have an internal thread 251 , and the internal thread 251 can cooperate with a positioning rod 31 to pack a plurality of optical discs 32 . At least one end of the positioning rod 31 has an external thread 311 for locking with the internal thread 251 .

Please refer to FIG. 12, when packing multiple optical discs 32, one end of the positioning rod 31 is first locked with a protective cover 20 for optical discs, and then the plurality of optical discs 32 are stacked on the optical disc through the positioning rod 31. Protective cover 20 . Then, another optical disc protection cover 20 is placed on the plurality of optical discs 32 and locked with the other end of the positioning rod 31 . Finally, the heat-shrinkable film 33 is spread and heated to complete the packaging of the plurality of optical discs 32 . The positioning rod 31 can continue to support the plurality of optical discs 32 after the consumer disassembles the heat-shrinkable film 33 , so that the consumer can take and place the optical discs 32 conveniently.

Since the height of the first side wall 22 is higher than that of the second side wall 23 , the optical disc protection cover 20 is in contact with the optical disc 32 through the first side wall 22 . After the packaging is completed, the stress applied to the optical disc 32 by the heat-shrinkable adhesive film 33 is supported by the optical disc protective cover 20 and concentrated in the central non-data area in contact with the first side wall 22, so it will not be affected by heat. The further shrinkage of the shrink film 33 causes the edge of the optical disc 32 to deform and warp, which affects the data access of the optical disc 32 . In addition, the height difference between the second side wall 23 and the first side wall 22 is about 2 mm to 5 mm. Therefore, after the heat-shrinkable adhesive film 33 presses the edge of the optical disc protection cover 20 inward, the second side wall 23 is the same as the first side wall 22. The optical disc 32 is close, but will not touch the data area of the optical disc 32, and even leave a gap of about 0.5 mm, which can prevent the optical disc 32 from being squeezed.

To sum up, the optical disc protective cover of the present invention is used for packaging multiple optical discs. The optical disc protective cover has a first side wall and a second side wall, wherein the first side wall is higher than the second side Wall, compared with the prior art, the optical disc protective cover of the present utility model, since the first side wall close to the central non-data area of the optical disc is higher, the stress generated during heat-shrinkable film packaging is mainly caused by the first side wall. Supported by the side wall, it will not affect the quality of the disc. Furthermore, the height difference between the second side wall and the first side wall is only about 2 mm to 5 mm. After the heat-shrinkable film exerts force to press the edge of the optical disc protection cover inward, there will be a gap between the second side wall and the optical disc. A small gap is left to prevent the data of the disc from being damaged. In addition, the optical disc protective cover has a plurality of first ribs to strengthen the structural strength of the protective cover body, so that the optical disc protective cover is not easily deformed.

The above are only preferred embodiments of the present utility model, and do not limit the utility model in any form. Although the utility model has been disclosed as above with preferred embodiments, it is not intended to limit the utility model.
