DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Please refer to FIGS. 2, 3 and 4. The present invention provides an optical disc can structure for deterring theft. In particular, this invention relates to a container for storing a lot of optical discs. The optical disc can includes a lower cover 1 and an upper cover 2. The lower cover 1 is made of a plastic material and it is circular. The top of the lower cover 1 receives optical discs (such as CDs, LDs, VCDs or DVDs etc.). The shape of the lower cover 1 is not limited to the above description and it can be modified according to the type of disc. On the center of the lower cover 1 there is a positioning column 11 that is integrally made. The positioning column 11 is vertically located on the top of the lower cover 1. The positioning column 11 can be a hollow column or is composed by a plurality of rib flakes. The positioning column 11 has an appropriate height for extending into the inner of the upper cover 2. The center hole of the optical disc is located at the positioning column 11 and the optical disc is positioned by the positioning column 11. The height of the positioning column 11 can be modified according to the upper cover 2. When the height of the upper cover 2 is increased, the height of the positioning column 11 is also increased. When the height of the upper cover 2 is decreased, the height of the positioning column 11 is also decreased.
The lower cover 1 has a blocking board 12 that surrounds the lower cover 1 and is circular shaped. The blocking board 12 surrounds the lower cover 1 continuously or discontinuously. In this embodiment, the blocking board 12 surrounds the lower cover 1 discontinuously. The blocking board 12 is located on the top of the lower cover 1 and is near the edge of the lower cover 1. The blocking board 12 is used for wedging the open edge of the bottom of the upper cover 2. Therefore, the upper cover is positioned on the lower cover 1.
The edge of the lower cover 1 extends outward to form a circular protruding edge 13. The protruding edge 13 is located on the outside of the blocking board 12. The external diameter of the protruding edge 13 of the lower cover 1 is larger than the external diameter of the upper cover 2. Therefore, the protruding edge 13 protrudes from the external edge of the upper cover 2. On the protruding edge 13 there is a plurality of wedging parts 14 and the wedging parts 14 are disposed with a space to each other. The wedging parts 14 are board bodies that are located on the top of the protruding edge 13 with an appropriate height. Under the wedging parts 14 individually there is a wedging slot 15. The wedging slot 15 fits with a wedging body 22 of the upper cover 2. The wedging body 22 and the wedging slot 15 form a wedging structure.
On the lower cover 1 there is a separating body 16 that is circular-board shaped and is integrally formed with the lower cover 1. The diameter of the separating body 16 is larger than the diameter of the positioning column 11. The separating body 16 is located on the top of the lower cover 1 and is located at the outside of the positioning column 11 with a proper distance for lifting the optical discs. The separating body 16 is used for supporting the optical discs with a proper height. The separating body 16 prevents the lowest optical disc from contacting the top of the lower cover 1 directly. So that, the optical discs don't suffer from the problem of the lower cover 1 scratching the optical discs.
The upper cover 2 is made of a plastic material and has a hollow circular body. The bottom of the upper cover 2 is open. The height of the upper cover 2 can be modified according to a manufacturer's requirements. When the quantity of the optical discs received by the upper cover 2 is increased, the height of the upper cover 2 is increased. If the quantity of the optical discs received by the upper cover 2 is decreased, the height of the upper cover 2 is decreased. A receiving space 21 is formed in the inner part of the upper cover 2 for receiving a plurality of optical discs. On the bottom of the external wall of the upper cover 2 there are a plurality of wedging bodies 22. The wedging bodies 22 correspond to the wedging slot 15 and each wedging body 22 has a protruding point 25. The protruding point 25 protrudes to the top of the wedging body 22 with a little height for enhancing the wedging strength of the wedging body 22 and the wedging slot 15. On the upper cover 2 there is a concave slot 23. The concave slot 23 is located at the center of the top of the upper cover 2 and corresponds to the upper end of the positioning column 11.
When the upper cover 2 covers the lower cover 1, the opening of the bottom of upper cover 2 is wedged and connected to the outside of the blocking board 12 and the upper end of the positioning column 11 of the lower cover 1 is plugged into the concave slot 23 located on the top of the upper cover 2. By rotating the lower cover 1 and the upper cover 2 in an opposite direction, the wedging bodies 22 are rotated and wedged into the corresponding wedging slot 15. The wedging bodies 22 and the wedging slots 15 form a wedging structure to make the upper cover 2 fasten with the lower cover 1 securely (as shown in FIG. 3). The protruding point 25 located on the wedging bodies 22 touches the inner wall of the wedging slot 15 to enhance the wedging strength of the wedging body 22 and wedging slot 15.
On the wedging part 14 of the lower cover 1, a fixing pin 17 is formed that is integrally made with the lower cover 1 (as shown in FIGS. 2B and 4). The fixing pin 17 is a column that is erected on the wedging part 17. The fixing pin 17 is connected with the wedging part 14 via two or more than two connecting parts 18. The fixing pin 17 protrudes to the top of the wedging part 14 with a proper height for unplugging the fixing pin 17 easily from the top. The lower end of the fixing pin 17 is plugged into the wedging slot 15 located under the wedging part 14. The lower end of the fixing pin 17 has an arc shape.
Each wedging body 22 of the upper cover 2 has a fixing hole 24 corresponding to the fixing pin 14 (as shown in the FIGS. 2A and 4.). The thickness of the front part 221 of the wedging body 22 wedged into the wedging slot 15 is thin for guiding the lower end of the fixing pin 17 entering the fixing hole 24. Therefore, when the wedging bodies 22 are rotated and wedged into the corresponding wedging slots 15, the lower end of the fixing pin 17 is slipped into the fixing hole 24 along the top of the wedging body 22. Thereby, the upper cover 2 is locked with the lower cover 1.
When the upper cover 2 is fastened with the lower cover 1 by wedging the wedging body 22 with the wedging slot 15, it utilizes the fixing pin 17 located on the wedging part 14 of the lower cover 1 by slipping into the corresponding fixing hole 24 located on the wedging body 22 of the upper cover 2 to achieve the locking function. A thief cannot rotate the upper cover 2 and the lower cover 1 to separate the upper cover 2 from the lower cover 1 and steal the optical discs in the optical disc can.
When the optical disc can and the optical discs received in the optical disc can are unsealed and sold, the fixing pin 17 is unplugged from the top. Because the fixing pin is connected with the wedging part 14 via a separately connecting part 18, the fixing pin 17 can be unplugged and thrown via imposing a force on the fixing pin 17 to make the fixing pin 17 separate from the wedging part 14. Therefore, the fixing pin 17 is separated from the fixing hole 24. Thereby, the wedging bodies 22 are rotated and separated from the wedging slot 15 to make the upper cover 2 separate from the lower cover 1 and the optical discs in the optical disc can can be taken off.
After the optical disc can is unsealed and opened, a fixing pin 17 is destroyed forever and cannot be recovered. Therefore, everyone knows that the optical disc can has been unsealed. The optical disc can of the present invention prevents the optical disc can from being opened and prevents optical discs inside from being stolen without being discovered.
The description above only illustrates specific embodiments and examples of the invention. The invention should therefore cover various modifications and variations made to the herein-described structure and operations of the invention, provided they fall within the scope of the invention as defined in the following appended claims.
