Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an openable / closable case for storing an optical disk such as a digital video disk (DVD) or a compact disk (CD).

[0002]

2. Description of the Related Art An optical disk is widely used as a record carrier for various kinds of information because of its small outer shape in addition to its large storage capacity. Conventionally, as a container for accommodating the optical disk, a box-shaped openable / closable case made of hard plastic, called a jewel box, has been widely used.

[0003] Such a case has a button-shaped member that engages with the center hole of the optical disc, and the optical disc is stored by fitting the center hole of the optical disc into the button-shaped member. When the optical disk stored in the case is taken out, the center hole of the optical disk is normally disengaged while pushing the button-shaped member downward to lift the optical disk upward.

[0004]

However, in the conventional storage case, since the center hole of the optical disk is tightly fitted in the button-shaped member and it is difficult to disengage the button, the outer peripheral portion of the optical disk is grasped by hand and lifted by force. I often removed them. When the optical disk is removed in such a manner, the optical disk may be bent in an unreasonable direction, so that the recording surface may be damaged or the recorded content may be destroyed in some cases.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems. It is an object of the present invention to easily store an optical disk and easily and reliably take out the stored optical disk. An object of the present invention is to provide an optical disk storage case that does not bend or be damaged when an optical disk is taken out.

[0006]

In order to achieve the above object, the present invention provides an openable / closable case for accommodating an optical disk, wherein an elastic tongue having a tip end projecting upward is provided inside the case. The cylindrical tongue is formed by a thick rib provided at the tip of the elastic tongue, and a ring-shaped ridge is provided inside the case to support an outer peripheral portion of the disk. It is characterized in that means for locking the outer peripheral edge of the disk are provided at one end of the ridge.

Embodiments of the present invention will be described below with reference to the drawings. 1 is a front view of the optical disk storage case of the present invention in an open state, FIG. 2 is a cross-sectional view of a main part of FIG. 1, FIG. 3 is a cross-sectional view taken along line AA of FIG. 1, and FIG. It is a part enlarged view.

An optical disk storage case 1 according to the present invention is a plastic openable case for storing an optical disk, in which a right case 1a and a left case 1b are connected to a back plate 1c.
It is provided continuously through. Right case 1a and left case 1b
Are formed in the shape of a quadrangular box, and a concave portion 7 is provided at an open end opposite to the back plate of each case for hanging a finger for convenient opening of the case.

On the inner surface of the right case 1a, an elastic tongue 2 having a distal end protruding upward from the base 8 is provided integrally with the case main body. The ribs 3 are provided integrally, thereby forming cylindrical disk locking means. In addition, the right case 1
A ring-shaped ridge 4 for supporting the outer peripheral portion of the disk is provided inside a. A flange 5 is provided at one end of the ridge 4 for locking the outer peripheral edge of the disk by pressing it from above. Also, the flange 5 of the ridge 4
On the opposite side, a notch 6 into which the fingertip enters is provided.

The optical disk storage case of the present invention is configured as described above, and a method for storing and removing the optical disk will be described below.

When the optical disk 9 (in FIG. 3 and FIG. 4, the storage state is indicated by a virtual line) is stored in the optical disk storage case 1 of the present invention, the end of the optical disk is connected to the flange 5 and the ridge. The optical disk 9 is inserted so as to be sandwiched in the gap between the four surfaces, and the optical disk 9 is placed so that the center hole 9a of the optical disk 9 is positioned on the disk locking means at the center of the case. Then, the vicinity of the center hole 9a of the optical disk 9 is pressed down with a finger. When the elastic tongue piece 2 is slightly bent downward by this pressing down, the thick rib 3 is slightly lowered. At this time, the locking portion 3 a provided on the outer edge of the upper end of the thick rib 3 on the side facing the flange 5. Enter the optical disk 9 so as to get over the center hole 9a of the optical disk 9, and the optical disk 9 is locked in a state where the thick rib 3 is tightly pressed against the inner periphery of the central hole 9a by the elastic restoring force of the elastic tongue piece 2 ( 3 and 4).

At this time, the outer peripheral portion of the optical disk 9 is supported by the ring-shaped protrusion 4. Thus, the optical disk 9 is fixedly held in the case 1.

Next, when removing the optical disk 9 from the case 1, the center disk locking means, that is, the thick rib 3 is pressed down from above with a fingertip. At this time, the engaging portion 3a of the thick rib 3 is disengaged from the center hole 9a of the disk, so that the notch 6 and the center hole 9a of the disk are taken out so as to be sandwiched between fingertips. Can be. At this time, since the engagement between the center hole 9a of the disk and the thick rib 3 is at only one position of the locking portion 3a, the engagement is easily released.

In short, the optical disk storage case 1 of the present invention can be easily obtained by simply inserting the end of the optical disk 9 into the flange 5 and inserting the center hole 9a of the optical disk 9 into the thick rib 3 of the disk locking means. 9 can be fixedly held. When the optical disk 9 is taken out of the case 1, the engagement with the center hole 9a of the disk is released only by pushing down the thick rib 3, and the optical disk 9 can be easily and reliably taken out.

[0015]

As described above in detail, according to the optical disk storage case of the present invention, the end of the optical disk is inserted into the flange, and the center hole of the optical disk is inserted into the thick rib of the disk locking means. The optical disk can be fixed and held easily and stored. On the other hand, only by pushing down the thick rib, the engagement with the center hole of the disk can be easily released, and the optical disk can be easily and reliably taken out, and the disk can be taken out. There is an effect that there is no possibility of being bent or damaged at the time. Moreover, the case of the present invention can achieve the above-described excellent effects with a very simple configuration.
