Description

Core of compact disk case

The present invention relates to a core that is a portion in which a CD is directly inserted and fixed in a compact disc (CD) case, and more particularly, to a core of an improved CD case to prevent the core from being broken when the CD is attached or detached.

Compact disc, or abbreviated CD (CD), is a storage medium capable of storing music, image data, or digital data in a large capacity.

1 illustrates a case for storing the compact disc 200 as described above. In general, the CD case 100 includes a front and rear plates 10 and 20 that can be opened and closed with hinged joints, and the back plate 20. It consists of a tray 30 inserted in and a core 40 protruding in the center of the tray 30.

The core 40 is integrally molded on the tray 30, and as shown in FIG. 2, twelve segments 41 are formed at a predetermined interval radially, and the ends of the segments 41 are in a L-shape. When the user presses the center hole 201 of the CD 200 to the bent portion 411, the fragment 41 on which the bent portion 411 is formed is slightly bent inwardly. Is inserted and fixed.

On the other hand, the tray 30 was manufactured to have some elasticity by combining polystyrene and rubber components, which are colorless and transparent polymer resins, in consideration of the above role of the core 40, but due to the rubber components. Since the color is opaquely manufactured in a black system, it does not give a neat appearance in appearance, and there is a disadvantage in that a cover fitted to the back plate 20 of the CD case 100 is not visible.

Therefore, in recent years, the CD case has been proposed in which the cover 30 is transparent so that the cover can be seen using only a polystyrene material. Thus, the tray 30 of the conventional CD case is weak in itself and has a CD. There is a problem that the core 40 of the tray 30 is easily broken during pressing.

The present invention has been devised to solve the above problems, and forms a cutout and a bent portion cut into a plurality of equal parts so that the CD can be inserted into the core of the tray, and at least one pair of the bent portions is diagonally formed. By interlocking each other in the direction to form a section having up and down elasticity and a section which is not fixed to flow, the core of the CD case does not easily break when the CD is pressed, and the inserted CD does not easily come out or come off. The purpose is to provide.

The core of the CD case of the present invention for achieving the above object is bent and protruded while the end portion of the fragment 41 is formed in a plurality of equal portions at radial intervals in the center of the tray 30. In the core 40 of the CD case that can press-in and store the compact disc in the bent portion 411, at least one pair of the bent portions 411 of the plurality of pieces 41 facing each other in a diagonal direction is formed. It is connected to the bridge 412 so as not to flow is characterized in that integrally formed on the tray (30).

In addition, the present invention forms the segment 41 into 12 equal parts, and connects three pairs of the bent portions 411 of the segment 41 opposed to each other by the bridge 412, but not between the bent portions It is characterized in that it is repeatedly connected to the place.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 is a view showing a core portion of the CD case of the present invention, Figure 3a is a plan view and Figures 3b and 3c are top and bottom perspective views, respectively.

First, referring to FIGS. 3A and 3B, the core of the CD case of the present invention has twelve fragments 41 cut radially toward the center at predetermined intervals, and the ends of the fragments 41 are bent in a L-shape. At the same time as the portion 411 is formed, six of the bent portions 411, that is, three pairs facing each other in the diagonal direction are integrated with each other by the bridge 412, and between the bent portions 411 which are bridged 412. The remaining three pairs of unbridged bends are arranged.

As shown in FIG. 3C, the bridge 412 is formed by integrally forming the bent portion 412 protruding from the segment 41 of the core 40 with the opposite bent portion, and is easily formed by a mold when the tray 30 is manufactured. It can be, and serves to prevent the bridged section (412) is broken when the CD is pressed.

With the above configuration, when CD-pressing the core 40 of the tray 30, even if the user's force is biased to one side, the biased force is applied before being applied to the unbridged bend portion 412. After being dispersed first by the three pairs of bent bridges 412, the CD is pressurized while the non-bridged bends are bent inward, so that the segments 41 and bent portions 411 of the core 40 are not broken. Or breakage can be prevented.

In addition, the once-indented CD is supported by the bridged bent portion to be stably fixed and stored without being easily detached from the core.

As described above, according to the present invention, the core of the CD case is formed of a plurality of pieces, but alternately bridges the bent portions protruding from the pieces, and the core is easily broken or broken even when a tray is manufactured using polystyrene as an address material. Can provide an effect.

In the above, the present invention has been described with the intersecting of the core in 12 equal parts and the number of the bridges with three in accordance with the above embodiments, but the present invention is not limited to the above embodiments, and the number of core fragments or bridges can be adjusted. Of course.

Claims (1)

As the sections 41 are formed in a plurality of equal portions with a predetermined interval radially in the center of the tray 30, the ends of the sections 41 are bent and protruded so that the compact disk can be press-fitted and stored in the bent portions 411. In the core 40 of the CD case, Cores of the CD case, characterized in that connected to the bridge (412) so that at least one or more pairs of the bent portion (411) of the plurality of pieces (41) facing in the diagonal direction does not flow.
