Description

The present invention relates to a disc cover that can be suitably used in handling a disk-type recording medium.
In the present specification, the “disc recording medium” is limited to a circular and plate-like one such as a CD, a CD-R, a CD-RW, or a DVD. In other words, “disk”.

When storing a disk in a box-type case, it is common to first store the disks in individual disk storage cases, and then store a plurality of the disk storage cases in a box-type case. .
As a disk storage case used in such a case, a ridge (rib-shaped one) formed in an arc shape on the flat case surface formed of an elastic material such as rubber or elastomer and surrounding the entire outer periphery of the disk ) Is known (see Patent Document 1).
This disk storage case is provided with an engaging portion so as to project radially inward from a plurality of circumferential positions of the protrusion, and by elastically deforming the engaging portion and the protrusion. The peripheral edge of the disc can be engaged and held, or can be released.

Even if the recording surface of the disk comes into surface contact with the case surface, the case itself is made of an elastic material, so that it can be prevented from being damaged.
Japanese Patent Laid-Open No. 2005-22728

This type of disk storage case known in the prior art is primarily intended to store a disk, and is therefore premised on holding the disk firmly engaged.
Therefore, a certain kind of procedure is required for storing and taking out the disc from the disc storage case, and an operating force for engaging and disengaging (elastic deformation of the engaging portion and the protrusion) is required. ing.
However, when using a computer, music equipment, etc. (hereinafter referred to as “computer, etc.”), if the disc is removed from the computer, etc. However, it is troublesome to store the disk in the disk storage case in an engaged and held state or to remove it from the disk storage case, which is very troublesome for the progress of the work.

The conventional disk storage case is formed of an elastic material such as rubber or elastomer, and thus has a lot of flexibility and is difficult to handle. Moreover, because of the material, even if the case shape is flat, there is a heavy presence in weight, and there are inconveniences regarding carrying and mailing.
The present invention has been made in view of the above circumstances, and can be held while protecting the disc so that the recording surface of the disc is not damaged even when the disc is temporarily placed temporarily. An object is to provide a disc cover.

  Another object of the present invention is to provide a disc cover that is easy to handle and does not cause weight inconvenience.

In order to achieve the above object, the present invention has taken the following measures.
That is, the disc cover according to the present invention includes a flat tray portion formed in a size that can cover the entire recording surface of a disc (= “disc type recording medium”: the same applies hereinafter), and the tray portion on the tray portion. And a positioning means capable of abutting in a state of preventing a lateral deviation with respect to the discs stacked on each other, and a protruding portion protruding to the outer peripheral side can be provided on the tray portion.
As described above, the disc cover according to the present invention is used so that the disc is overlapped on the tray portion, and this overlapped state is held by the positioning means so as not to be laterally displaced. It can be suitably used for placing.

Further, such an overhanging part can serve as a role for preventing rolling or as a function of a supporting leg when, for example, the disk cover according to the present invention is leaned against another object. Further, even when the disk covers according to the present invention are stacked and the respective disk covers are temporarily engaged and integrated, the present invention can be beneficially used as rolling prevention and support legs.
Furthermore, when the disk covers according to the present invention are overlapped with each other by changing the shape, color, display, number of formations, arrangement, and the like of the overhang portions, they can also be used as indexes for each disk cover.

The positioning means may be a center boss that is provided in a bulging state from the tray portion and can be fitted into a central hole formed in the disk.
Such a center boss is preferable in that it can be simplified as a structure in which the disk is engaged and held with respect to the tray portion, and at an easy and stable position as an operation for engagement and disengagement at this time. It is preferable in a certain point.
The center boss is formed so as to protrude from the center hole when the center hole of the disk is fitted, and the back side of the center boss can absorb the amount of protrusion from the center hole. It is preferable that a fitting recess is formed.

By doing so, when the disc covers according to the present invention are stacked with the center hole of the disc fitted to the center boss, the center bosses interfere with each other between the disc covers. Absent. Therefore, a stable and dense overlapping state can be achieved, which is beneficial for space saving.
The center boss is provided with an engaging means that is detachable between a portion protruding from the center hole and a fitting recess formed on the back side of the center boss when the center hole of the disc is fitted. Can do.

In this way, when the disc covers according to the present invention are stacked with the center hole of the disc fitted into the center boss, each disc cover can be temporarily engaged and integrated. Convenient.
The tray portion supports a portion other than the recording surface of the disc superimposed on the upper portion (referred to as “outer peripheral side non-recording area” and “center side non-recording area” described later), and the recording surface is placed on the tray portion. A support base that can be floated and held can be provided.
By doing so, there is no risk of scratching the recording surface of the disc by the tray portion, which is preferable.

The tray part may be provided with a front side engaging part that protrudes beyond the thickness of the disk superimposed on the upper part, and a back side engaging part that is detachable with respect to the front side engaging part.
The engagement relationship between the front-side engagement portion and the back-side engagement portion can be employed as a substitute for the engagement means provided between the center bosses described above or in parallel with the engagement means. is there.
The engagement relationship between the front-side engaging portion and the back-side engaging portion is the relationship between the center bosses described above in that each disc cover can be prevented from rotating when the disc covers according to the present invention are stacked. Other advantages than the combined means can be produced.

  The disc cover according to the present invention can be held while protecting the disc so that the recording surface of the disc is not damaged even when the disc is temporarily placed temporarily. Further, it can be easily handled as a disc cover, and there is no weight inconvenience.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The disk 100 has a disk-shaped one surface as a recording surface 101 and the other surface as a display surface 102 formed as a printing surface, a label attaching surface, or the like. Is formed with a central hole 103 for engaging with a drive device such as a computer 105 to receive a rotational force. Various structural circumstances relating to these disks 100 are well known.
On the recording surface 101, an outer peripheral non-recording area is formed so as to border the outer periphery of the disk shape, and a central non-recording area is formed so as to surround the opening peripheral portion of the central hole 103. It is common that
[First Embodiment]
1 to 7 show a first embodiment of a disc cover 1 according to the present invention. As shown in FIG. 1, the disc cover 1 has a flat tray portion 3 formed to have a size that can cover the entire recording surface 101 of the disc 100. On the other hand, the disk 100 is used so as to be overlaid (overlaid).

The disk cover 1 also has positioning means 4 that prevents the lateral displacement by contacting the disk 100 when the disk 100 is superimposed on the tray portion 3.
In the first embodiment, the tray section 3 has the same shape as the disk 100 in plan view. Note that ABS resin, polycarbonate, polyethylene, or the like can be used as a material for forming the tray portion 3.
Further, the positioning means 4 is configured by fitting the center hole 103 of the disk 100 to the center boss 5 bulging at the center of the tray section 3.

Therefore, for example, as shown in FIG. 2, in the process of using the computer 105 on a desk, when the disk 100 is inserted into and removed from the drive device (disk tray 106) on the computer 105 side, the computer 105 is removed. It is only necessary to temporarily place the disc 100 as it is on the disc cover 1 (the tray section 3) according to the present invention.
The state in which the disk 100 is superposed on the tray unit 3 is held by the positioning means 4 (center boss 5) and does not shift laterally. Therefore, the work progress of the computer 105 causes the disk 100 to be temporarily placed or taken up. There is no need to interrupt every time you do.

The tray portion 3 includes a support base portion 10 that protrudes into a ring-shaped rib at a corresponding position (near the outer periphery of the tray portion 3) that can support the non-recording area on the outer peripheral side of the recording surface 101, and the center side of the recording surface 101. A support base 11 protruding in a circular trapezoidal shape is provided at a corresponding position (center of the tray part 3) that can support the non-recording area (see FIG. 4).
These support base portions 10 and 11 are formed at the same height from the surface of the tray portion 3, and support the disc 100 in cooperation with each other. In this supported state, the recording surface 101 is held in a floating state on the tray portion 3, and no scratches are generated.

As shown in FIG. 5, the center boss 5 employed as the positioning means 4 is formed in a size that can be fitted into the central hole 103 of the disk 100 without rattling. The height H is a dimension capable of projecting from the center hole 103 in the fitted state (the projecting amount is h).
A push button portion 15 is formed at the center of the center boss 5, and a circumferential groove 16 is formed around the push button portion 15. For this reason, a ring-shaped bank portion 17 is formed so as to surround the circumferential groove 16.

Then, after cutting the bank portion 17 from the groove bottom of the circumferential groove 16, a plurality of slits 18 extending radially outward to the support base portion 11 are formed in a radial arrangement around the push button portion 15. Yes.
Therefore, as shown in FIG. 6, when the push button portion 15 is pressed, the cut dam portion 17 is bent downward, and the center boss 5 is elastically deformed so that the center portion is depressed as a whole. As a result, the diameter of the center boss 5 is reduced, so that the center hole 103 of the disc 100 fitted to the center boss 5 is released from the fitted state. The disc 100 can be taken up.

In order to easily cause such elastic deformation of the center boss 5, it is preferable that the back surface of the tray portion 3 (a region substantially corresponding to the central support base portion 11) is recessed upward.
Such a picking up operation of the disc 100 can be accurately performed with one hand. Note that the operation of fitting the center hole 103 of the disk 100 into the center boss 5 is only required to lightly push the disk 100 with the center boss 5 and the center hole 103 aligned.
As described above, the bulging height H of the center boss 5 is a dimension that protrudes from the center hole 103 even after the center hole 103 of the disk 100 is fitted. In order to make the absorption possible, a fitting recess 23 is formed on the back side of the center boss 5.

Accordingly, as shown in FIG. 7, even when the center hole 103 of the disc 100 is fitted to the center boss 5, the disc 100 covers according to the present invention can be stacked in a dense overlapping state. At this time, the center bosses 5 do not interfere with each other between the covers of the disks 100, which is beneficial for space saving.
In the first embodiment, a taper surface in the upward deflation direction is formed with respect to the outer periphery of the fitting recess 23.
Therefore, when the upper peripheral surface of the center boss 5 comes into contact, a centripetal action occurs between the two, and the disc 100 covers are concentrically overlapped with each other. In addition, there is an advantage that there is no lateral shift between the two under the overlapped state.

By the way, in the disc cover 1 of this 1st Embodiment, the overhang | projection part 25 projected over the outer peripheral side with respect to the tray part 3 is provided. The projecting portions 25 are, for example, small pieces formed in the shape of a fish cage, and two are provided at a predetermined interval in a relatively close arrangement.
For example, as shown in FIG. 2, these overhang portions 25 prevent rolling when the disc cover 1 according to the present invention is leaned against another object (in the example shown, a document case 110 placed on a desk). It becomes a role. Further, in the state where the disc 100 is superposed on the tray portion 3, the ends of the overhang portions 25 and the outer edge of the disc 100 located in the middle thereof are on the same plane. It becomes the role of.

Further, if the shape, color, display, number of formations, arrangement, etc. of the overhanging portions 25 are appropriately changed, when the disc covers 1 according to the present invention are stacked, an index for each disc cover 1 is used. It can also be used as
In addition, although an envelope-shaped disk wrapping material having a bag portion for storing the disk 100 is also known, the disk cover 1 can be stored in the envelope-shaped disk wrapping material while being superposed on the disk 100. it can. Therefore, the recording surface 101 of the disc 100 is not damaged even if dust, sand, or the like is present inside the bag portion of the envelope disc packaging material.
[Second Embodiment]
FIG. 8 shows a second embodiment of the disc cover 1 according to the present invention. The disc cover 1 of the second embodiment is different from the first embodiment only in that the engaging means 30 is provided for the center boss 5.

The engaging means 30 includes a portion protruding from the center hole 103 when the center hole 103 of the disc 100 is fitted to the center boss 5 (an upper end of the boss), and a fitting recess formed on the back side of the center boss 5. 23.
In the illustrated example, the engagement convex portion 31 projecting in a dowel shape at the upper peripheral inner edge of the bank portion 17 of the center boss 5 and the outer peripheral portion of the lower surface of the peripheral groove 16 of the center boss 5 are doweled. The engaging means 30 is configured by engaging and disengaging engagement recesses 32 formed in a hole shape.

A plurality of engaging convex portions 31 and engaging concave portions 32 may be provided at equal intervals in a plurality of locations in the circumferential direction. It is also possible to form the engaging convex portion 31 as a ring-shaped protrusion and the engaging concave portion 32 as a ring-shaped groove. Thus, the shape, number of formation, and arrangement of the engaging protrusions 31 and the engaging recesses 32 are not limited at all.
In addition, the engagement convex portion 31 and the engagement concave portion 32 can also be reversed in relative positional relationship with each other (that is, the engagement concave portion 32 is provided on the upper peripheral inner edge portion of the bank portion 17 and the circumferential groove 16 is formed. It is possible to provide the engaging convex portion 31 on the outer peripheral portion of the lower surface).

When such an engaging means 30 is employed, when the disc covers 1 according to the present invention are overlapped with the center boss 5 in a state where the central hole 103 of the disc 100 is fitted, the disc covers 1 are temporarily attached. It can be used in such a way that it can be engaged and integrated, which is convenient.
FIG. 2 shows a state in which a plurality of disc covers 1 integrated with each other are placed on the left side of the desk.
In this case, if the overhanging portions 25 are aligned in the same position in the individual disk covers 1, the overhanging portions 25 can be used effectively for preventing rolling and supporting legs.
[Other Embodiments]
The tray portion 3 can be formed in a square shape as shown in FIG. 9, or can be formed in a hexagonal shape as shown in FIG. Of course, the tray part 3 can also be formed in other shapes (for example, an ellipse, an oval, a polygon other than a quadrangle or a hexagon).

When the tray unit 3 has a shape larger than that of the disc 100, a portion that protrudes outward from the disc 100 in a state where the disc 100 is overlaid (a portion that is exposed in plan view and is an overhang portion). 25), the front side engaging part 40 protruding beyond the thickness of the disk 100 superimposed on the upper part, and the back side engaging part 41 (in short, detachable with respect to the front side engaging part 40) You may make it provide the thing formed as a hole, a recessed part, or a slit part on the back side of the tray part 3).
The engagement relationship between the front-side engagement portion 40 and the back-side engagement portion 41 can be employed as a substitute for or in parallel with the engagement means 30 (see FIG. 8) provided between the center bosses 5 described above. is there.

The engagement relationship between the front-side engaging portion 40 and the back-side engaging portion 41 provides an advantage that each disc cover 1 can be prevented from rotating when the disc covers 1 according to the present invention are overlapped with each other (the above-mentioned) In some cases, the engagement means 30 of the second embodiment can also obtain the advantage of this detent. However, in the engagement means 30, the engagement protrusion 31 is a ring-shaped protrusion and the engagement recess 32 is a ring-shaped protrusion. Because it includes the groove, it is not an advantage that can be definitely obtained).
Therefore, in the disk cover 1 of the present embodiment, an action such as rolling prevention can be obtained without separately providing the overhanging portion 25 that protrudes to the outer peripheral side of the tray portion 3. Of course, the outer peripheral part of the tray part 3 can also act as an index.

The present invention can be appropriately changed according to the embodiment in addition to the above embodiments.
For example, the positioning means 4 may be other than the center boss 5 (one that contacts the outer periphery of the disk 100).
