Description

CD case {CD CASE}

The present invention is a compact disc (here compact disc is referred to as Compact Disk (CD), Digital Video Disk (DVD), CD-R, CD-RW, DVD-R ... It refers to a case which can store and carry digital media with the current Compact Disk size to be stored collectively.) It's about a case designed to hold a CD.

In the case of the conventional CD case shown in FIG. 1, only one disc can be stored in one case. The conventional CD case includes a front cover (0-1) and a rear cover (0-2) and a CD storage case. (0-3) is assembled. In more detail, the front cover (0-1) and the rear cover (0-2) are rotatable on both sides of the extension portions (0-7 positions) to open and close the case, and the CD storage case (0 -3) is fastened to the rear cover and is fixed to prevent movement.

However, in the conventional CD case, since the front cover and the back cover do not have much elasticity due to the characteristics of the material in the three components are assembled with each other, a hole is formed at one side of the back cover (0-2) and the corresponding position is Fine protrusions on the front cover (0-1) are formed in the extension portion (0-7) to be opened and closed by their combination, so the extension portion (0-7), which is vulnerable to a minor impact, is broken or extended. There is a problem that the fixed compact disc is pulled out when the protrusion formed on the portion 0-7 is easily detached or the impact is applied. In addition, since the three components are separately manufactured by injection, etc., a process of assembling them is required. Therefore, the three components are separately injected, and thus a large production cost is required. There is a problem. In addition, since one CD is stored in one CD case, there are inconveniences of increasing the volume to store or carry multiple CDs.

On the other hand, as a conventional CD case for storing and carrying a large number of CD cases, the 'portable CD case' of Utility Model Registration No. 188243 has been introduced. The conventional 'portable CD case' is provided with a plurality of diaphragms that can be pivotally mounted between the upper housing and the lower housing and accommodate the CD therebetween.

However, the CD case is required to separately manufacture the upper housing and the lower housing based on aluminum, as well as to assemble them separately, and also to assemble a separate diaphragm, the assembly process is added, a lot of manufacturing costs are required, When the CD case is stored in the CD case storage box and the like, there is a problem in that the specifications do not coincide with each other.

Accordingly, the present invention was created to solve the above problems, while reducing the manufacturing cost by reducing the injection process and assembly process in manufacturing the CD case, while maintaining the same size as the conventional CD case in use The purpose of the present invention is to provide a CD case for storing a plurality of CDs, to prevent breakage of the CD or breakage of the case under external shocks, and to be compatible with the existing CD case storage box.

In order to achieve the above object, the present invention uses a material having a hinge characteristic of a conventional CD case consisting of three components, and is made through one injection operation, but has a CD holder that can attach and detach the CD to the front cover and the rear cover. Each can be configured, and the trays with CD holders on both sides to separately store the CDs can be separately assembled and then easily assembled to the CD case. In addition, it is necessary to change the structure of the weak part that is easy to break during impact.

The structure of the present invention is largely composed of a case (1) and the tray (20).

First, the case 1 of the present invention is formed as one body by integrally forming the front cover 2 and the rear cover 3 as shown in Figures 2 to 3, the opening and closing of the case 1 Using an injection material having a hinge characteristic, but forms a center cover 14 for connecting the front cover and the rear cover, each connecting portion forms a flexible hinge (11).

At the front end of the front cover is provided with a main rib (6) having an end formed on the outer circumferential surface to be assembled with the rear cover (3) at the same time to prevent deformation, such as bending, and the back cover corresponding to the front end The secondary ribs 7 protrude from the thickness of the main ribs from each other so that the main ribs 6 and the auxiliary ribs 7 overlap each other and may be seated.

In addition, the flexible hinge portion 11 connecting the front cover 2 and the rear cover 3 is configured to be remarkably thin in thickness as shown in FIG. 5 so as to bend and act as a hinge for opening and closing. In the case 1 configured as described above, when the CD case is closed, the main rib 10 of the front cover 2 is seated to the outside of the auxiliary rib 11 of the rear cover 3. In this case, the guide rib 10 as shown in FIG. 6 serves to guide the auxiliary rib 7 of the rear cover to fit into the inner surface of the main rib 6 when the CD case is closed. . That is, when closing the CD case, since there are two flexible hinge portions 11 serving as opening and closing axes, the ends of the covers 2 and 3 can be pushed from side to side without satisfactorily crossing each other. In order to prevent the installation of a plurality of guide ribs (10).

In addition, on the outer surface of the auxiliary ribs 7 of the rear cover, the locking jaws 13 protruding to a predetermined height are preferably installed at two positions on both sides, and the locking jaws 9 and the inner surfaces of the main ribs 6 are provided. When the CD case is closed, the locking groove 12 recessed to a predetermined depth to correspond to the locking groove 8 and the locking jaw 9 are inserted into and fixed to each other, thereby maintaining the closed state.

On the other hand, the CD holder (4) (5), which is a part to secure the CD is formed integrally with the cover (2) (3), respectively, to protrude in the form of a cylindrical tube, but by removing a protrusion by a predetermined angle three When the case 1 is closed, the projections of each of the CD holders 4 and 5 of the front cover and the rear cover cross each other so that the projection pieces of each CD holder do not interfere in space. Do not. That is, when the case 1 is closed, the first CD holder 4 and the second CD holder 5 cross each other to form a cylindrical tube.

4, a slightly protruding jaw is formed at the outer end of the CD holders 4 and 5, and the jaw has a fixing hole (not shown) formed in the center of the CD holder. 4) (5) to prevent the separation to be fixed when inserted, the CD holder (4) (5) is elastically bent to be inserted in the insertion of the CD, after being inserted into the jaw protruding The CD will remain stationary unless you intentionally leave it.
