In addition, it is thin and easily broken, so it is stored in a case. This case generally has a resin case body formed in a shallow box shape having an open upper surface with a square shape in a plan view, and a shallow box shape formed with an open lower surface and being slightly larger than the case body, and opposing each other. One end of one set of side surfaces is provided with a cover pivotally attached to the opening and closing by fitting a projection and a recess. The center of the inner bottom surface of the case body has a spring property and is opened at the center of the CD. The centering hole is fitted with a positioning projection.

[0003]

However, in the above-mentioned conventional CD storage case, the projections and recesses cannot be formed large due to the mold release during molding. When the cover is opened widely or an external force such as bending or twisting is applied to the cover or the case main body, the projection easily comes off from the concave portion and the cover comes off from the case main body. There was also a problem that the case was too simple and lacked in design.

Accordingly, the present invention has been made in view of the above-mentioned conventional problems, and the purpose of the present invention is to prevent the cover from easily falling off and falling off, and to provide a novel design. To provide a storage case rich in taste.

[0005]

According to the present invention, there is provided a base plate formed in a flat plate shape and provided with an article storage concave portion for storing an article made of a thin body at the center of the upper surface.
A pair of left and right covers that can open and close in a direction approaching and separating from each other and cover the base plate; and a guide groove that extends long in a moving direction of the cover is provided on a lower surface of the base plate; Are provided with a slide body which is prevented from coming off and is slidably inserted.

[0006]

In the present invention, the slide body is inserted into the guide groove in such a manner as to prevent the cover from coming off, so that each cover is inseparably attached to the base plate, and slides along the guide groove when the cover is opened and closed. Then, the covers are moved in a direction to approach and separate from each other.
