[0001]

[Industrial applications]

 The present invention relates to a compact disc storage container that can be used for a compact disc storage case, a book, and the like.

[0002]

[Prior art]

 2. Description of the Related Art In recent years, as a CD storage container used for a compact disc (hereinafter abbreviated as CD) storage case, a CD-type holder for a CD, etc., a plastic container having a CD storage recess with a holding member in the center is used. Tray is common. This holding member is a circular convex portion for fitting, in which a plurality of radially divided streak members are formed in a rising shape, and the central hole of the CD is locked to the convex portion to hold the CD. is there.

[0003]

[Problems to be solved by the device]

 However, such trays made of plastic have problems that the structure of the holding member is complicated and they are easily damaged, CDs are not smoothly attached and detached, and the cost becomes high. Is difficult and is a cause of environmental pollution.

The present invention solves the above-mentioned conventional problems, and can be manufactured by using only papers without using such a plastic tray, and can realize a simple structure, light weight, and cost reduction. Furthermore, it is an object to provide a CD storage container that is easy to recycle and has little environmental pollution due to waste.

[0005]

[Means for Solving the Problems]

 The CD storage container of the present invention is formed with a circular recess for storing a CD corresponding to the diameter of a CD, and the peripheral rising surface of the circular recess is formed to be slightly expanded downward so that the peripheral edge of the stored CD rises. It is held in a sandwiched manner by abutting the inclined surface. A convex portion for placing a CD is formed in the center of the bottom surface of the circular concave portion, and the non-recording surface of the central portion of the CD is placed on this convex portion.

In the CD storage container of the present invention, papers having appropriate strength such as cardboard, cardboard and recycled paper are usually used, but resins such as polystyrene, polyethylene and polypropylene can also be adopted. The paper forming the circular recess of the CD container according to the present invention has a strength that serves as a stable substrate, and has a thickness that allows a CD to be inserted into the circular recess. It is desirable that the paper forming the bottom surface of the circular recess of the CD storage container has a smooth surface so as not to damage the recording surface of the CD even if the recording surface comes into contact with the recording surface.

The circular recess of the CD storage container of the present invention is formed to have a diameter corresponding to the diameter of the CD. That is, the diameter of the upper surface of the circular recess is approximately the same as or slightly smaller than the diameter of the CD, and the diameter of the lower surface of the circular recess is slightly larger than the diameter of the CD.

The circular recess of the CD storage container of the present invention is formed such that the rising edge of the peripheral edge of the circular recess is slightly inclined downward from the upper surface of the circular recess, and the elasticity of cardboard, for example, is used. The peripheral edge of the CD placed in the circular recess is raised and brought into contact with the inclined surface to be locked. The angle of inclination of the rising surface is preferably 80 to 89 degrees inward with respect to the bottom surface, and more preferably 87 to 88 degrees. In addition, the slope of the rising surface may have a straight cross section or a slightly curved cross section. Further, the inclination of the rising surface may be formed on the entire peripheral edge of the circular recess or may be formed partially. However, in the case of partial formation, it is necessary to provide at two locations, preferably three locations, at positions symmetrical with respect to at least the center point.

The circular recess for storing a CD is usually formed by punching a cardboard with a punch. This cardboard is required to have a thickness such that the surface of the CD does not come out of the concave portion when the CD is placed in the circular concave portion and placed on the convex portion for CD mounting described later, and usually 2 mm to 5 mm. The thickness of is used.

In the central portion of the bottom surface of the circular concave portion of the CD container of the present invention, a convex portion for placing a CD is formed. When the CD is put into the circular recess, the non-recording surface around the center hole of the CD is placed on the convex portion, and the recording surface of the CD is held in non-contact with the bottom surface. The shape of the convex portion is not particularly limited, but a circular shape is preferable, and other shapes such as an elliptical shape and a regular polygonal shape can be adopted. Within the range of the above-mentioned shape, this convex portion is formed to be smaller than the diameter of the non-recording surface of the CD and sufficiently larger than the diameter of the center hole of the CD so that the CD can be stably held.

The height of the protrusion is usually 0.3 mm to 1 mm. This convex portion is usually formed integrally with the cardboard forming the bottom surface by press molding, but only the convex portion may be molded and attached to the cardboard forming the bottom surface.

At least one, and usually four, finger ejecting slots for ejecting CDs are provided at equal intervals on the periphery of the circular recess for accommodating a CD of the present invention. The CD storage container of the present invention is a cardboard punched out to a diameter corresponding to the diameter of a CD, and a cardboard having a convex portion as the bottom is molded, and the cardboard is positioned so that the convex portion is located at the center and is bonded and integrated. Form. To store a CD in the container of the present invention, simply fit the outer periphery of the CD into the opening of the circular recess for storing and push the CD from above to store it easily.

The CD storage container of the present invention can be applied to the storage of disc-shaped recording media such as CD-ROM, magneto-optical disk (MO), etc. in addition to CDs of various sizes. It can be used as a tray for sticking to cases and books, and as a container for binding CDs in magazines.

[0014]

[Action]

 The outer peripheral edge of the CD accommodated in the circular recess is brought into contact with and locked to the rising edge of the peripheral edge of the circular recess for storing CD which is inclined downwardly slightly. The non-recording surface around the center hole of the CD is placed on the convex portion formed on the bottom surface of the CD-containing circular concave portion, and the CD recording surface is held in non-contact with the bottom surface.

[0015]

【Example】

 Hereinafter, an example of the CD storage container of the present invention will be specifically described with reference to the accompanying drawings. FIG. 1 is a perspective view of the storage container of the present invention, and FIG. 2 is an end view taken along the line AA in the state where the storage container of FIG. 1 stores a CD.

As shown in the figure, the CD storage container 1 of the present invention is provided with a circular storage recess 3 having a circular opening corresponding to the diameter of the CD 2 on the substrate. The peripheral edge rising surface 5 is formed over the entire circumference so as to incline in a downwardly expanding manner. Further, a convex portion 6 for mounting the CD 2 is formed in the central portion of the bottom surface 4 of the storage circular concave portion 3. Furthermore, four CD picking finger slots 7 are formed around the storage circular recess 3.

[0017]

[Effect of device]

 Since the CD storage container of the present invention does not use a plastic CD storage tray or a holding member as compared with the conventional container, the weight can be reduced and the manufacturing is extremely easy and the manufacturing cost can be greatly increased. Can be suppressed to In addition, since it can be manufactured only from paper such as cardboard, it is easy to recycle and there is no concern about environmental pollution.
