[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates generally to a compact disc (hereinafter referred to as “CD”) case, and more particularly, to a CD case in which the number of CDs that can be stored with the same thickness as a conventional CD case is greatly increased.

[0002]

[Prior art]

 After the invention of the CD, people have realized that the CD is easy to store and carry, as well as being very convenient to use the information. Due to this competitive advantage, CDs are a large part of the information market. Due to the great demand for CDs, high-volume CDs have created the problem that people have to find a suitable way to store all their CDs. FIG. 7 shows a conventional case 50 for storing a CD (not shown). The case 50 includes a first cover 51 and a second cover 53 pivotally connected to the first cover 51. The second cover 53 is shaped to receive the plate 55. The plate 55 is provided with a recess 511 and has a circular protrusion 552 formed in the center thereof. The CD (not shown) is formed in a disk shape having a through hole (not shown) in the center. The diameter of the through hole in the central portion is slightly smaller than the diameter of the circular protrusion 552. Therefore, when the CD is placed on the circular protrusion 552 of the recess 551, the circular protrusion 552 is deformed by pushing the CD and extends through the through hole of the CD. Therefore, the circular protrusion 552 comes into contact with the edge of the through hole to hold the CD fixedly. The case 50 shown in FIG. 7 can accommodate only one CD. The plate 55 is very different in shape and material from the first and second covers 51, 53. Therefore, the plate 55 is manufactured in another manufacturing line, which increases the manufacturing cost. Furthermore, since the plate 55 and the first and second covers 51 and 53 are made separately, it is necessary to attach the plate 55 to the first and second covers 51 and 53, which increases the manufacturing cost. ..

From the above, a market including the first cover 51, the second cover 53 pivotally connected to the first cover, and the plate 55 fixed to the second cover is provided. The sales case 50 cannot meet the needs of users, and thus needs to be improved or modified.

[Problems to be solved by the device]

 An object of the present invention is to provide a CD case having the same thickness as a conventional CD case and capable of accommodating more CDs.

[0005]

[Means for Solving the Problems, Functions and Effects of the Invention]

 The CD case of the present invention includes an upper cover and a lower cover integrally formed with the upper cover and pivotally connected to the upper cover. The upper cover has a plurality of first protruding bars at its central portion, and the lower cover has a plurality of second protruding bars at its central portion. The bars of the upper cover and the lower cover are each formed to have a circular shape. The bars are arranged at equal intervals so that when the upper cover and the lower cover are closed, the bars of the upper cover and the bars of the lower cover fit between the one bar and the other bar. It is arranged. Therefore, since the bars are formed on the upper cover and the lower cover respectively, the CD case of the present invention stores two CDs on the upper cover and the lower cover, respectively. be able to.

In addition, the CD case of the present invention includes an upper cover, a lower cover integrally formed with the upper cover and pivotally connected to the upper cover, and a connecting portion of the upper cover and the lower cover. And two retainers formed at the ends. Therefore, the mounting member having a size smaller than that of the case and including the first and second side surfaces can be held between the two retainers. The mounting member has a plurality of protrusions integrally formed on each of the first and second side surfaces. The protrusions on the first and second side surfaces are formed to have a circular shape. When the upper cover and the lower cover are closed with the mounting member sandwiched therebetween, the bars and the protrusions of the first and second side faces and the upper cover and the lower cover are formed. The bars are alternately arranged at equal intervals so that they fit together. Therefore, since the mounting member is arranged between the upper cover and the lower cover, and the bars and the protrusions are alternately arranged, the CD case of this school is the same as the conventional case. You can store 4 CDs with the same thickness.

[Embodiment of the invention]

 FIG. 1 shows a preferred embodiment of a compact disc (CD) case 10 according to the present invention. The case 10 is shaped to have an upper cover 11 and a lower cover 13 integrally and pivotally connected to the upper cover. The top cover 11 comprises a first flange 113 along its edge. The lower cover 13 likewise comprises a second flange 133 along its edge. The first flange 113 and the second flange 133 are arranged so that the first flange 113 surrounds the second flange 144 when the upper cover 11 and the lower cover 13 are closed. A plurality of first bars 111 each formed in an arc shape and arranged in a generally circular shape are integrally provided on the upper cover 11, and similarly, a plurality of second bars 131 arranged in a generally circular shape. Are integrally provided on the lower bar 13. The first and second bars 111 and 131 are such that when the upper cover 11 and the lower cover 13 are closed, the first bar 111 and the second bar 131 fit, and the second bar fits between the first bars. They are arranged alternately so that they fit.

2 and 3 show the first bar 111 and the second bar 131 in cross section. The first and second bars 111 and 131 are formed to have inclined side surfaces 112 and 132, respectively. Since the first and second bars 111 and 131 are made of an elastic material such as plastic and have inclined side surfaces 112 and 132, and the circle formed by the first and second bars 112 and 132. Since the outer diameter of the CD is slightly larger than the diameter of the through hole (not shown) in the center of the CD, the first and second bars 111 and 131 can easily extend through the through hole in the center of the CD. Therefore, the CD can be held in place.

1 and 4 show another preferred embodiment of the CD case according to the present invention. The CD case 10 further includes first and second retainers 21 and 22 formed at opposite ends of the connecting portion between the upper cover 11 and the lower cover 13, respectively. The first retainer 21 has a closed rectangular shape and has an opening 211. The second retainer 22 is formed to have a cutout 221. Therefore, the plate 30 which is the mounting member having the first projecting portion 31 at one end of the bottom edge portion and the second projecting portion 33 at the other end is attached to the opening 211 of the first retainer 21. The first protruding portion 31 is inserted into the second retainer 22 and the second protruding portion 33 is disposed in the notch 221 of the second retainer 22, so that the first and second retainers 21 and 22 are detachably fixed. can do. The first protrusion 31 has a first portion 311 and a second portion 312 integrally formed with the first portion (see FIG. 5). The first portion 311 is circularly shaped and the second portion 312 is shaped to match the shape of the opening 211 1 of the first retainer 21. Therefore, when only the first portion 311 of the first protrusion 31 is inserted into the opening 211 of the first retainer 21 and the second protrusion 33 is arranged in the notch 221 of the second retainer 22. The plate 30 can pivot. The plate 30 has a first side surface (not shown) having a plurality of first protrusions 35 which are formed in a circular shape and which are alternately arranged with the first bars 111 of the upper cover 11. 13 second bars 131 and second side surfaces (not shown) having a plurality of second protrusions 37 alternately arranged. Therefore, when the upper cover 11 and the lower cover 13 are closed, the first and second bars 111 and 131 engage with the first and second protrusions 35 and 37, respectively. By disposing the plate 30 having the first and second protrusions 35 and 37, the CD case 10 of the present invention can accommodate four CDs with the same thickness as the conventional CD case.

FIG. 6 shows the CD case in a closed state. Since the first bars 111 of the upper cover 11 are alternately arranged with the first protrusions 35 on the first side surface of the plate 30, the thickness of the case 10 does not increase, and the case 10 has more CDs. Can be accommodated.
