Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a kind of CD case, and more particularly to a CD case having an improved opening / closing structure, which can be opened easily with one hand, is convenient for operation, and has practical utility.

[0002]

[Prior art]

 Shown in FIG. 1 is a well-known CD case 1, which comprises a main body 11, a CD storage sheet 12 and an outer lid 13, and a few large circular holes 14 and small circular holes at specific positions of the main body 11. 15 is provided and when the CD containing sheet 12 is combined with the main body 11, the projection 121 of the CD containing sheet 12 is fitted into the small circular hole 15 for positioning, and the outer lid 13 has two wing pieces 16 extending to the bottom. Then, the wing pieces 16 are made to project at appropriate positions and one projecting block 161 is provided for each, and the projecting block 161 of the outer lid 13 is fitted into the great circular hole 14 at the tail end of the main body 11, The bottom of the outer lid 13 is rotatably combined with the tail end of the main body 11, and a protrusion 17 is provided at an appropriate position on the front end of the outer lid 13. When the outer lid 13 covers the main body 11, the protrusion 17 is a small circular hole. Mates with 15 to form temporary positioning.

The known CD case is considerably inconvenient when opening, and it is necessary to pay attention to the opening direction, and it cannot be opened if the opening force is inappropriate or the direction is wrong. It was

In addition, in the well-known CD case, both hands must be used at the same time for opening, that is, by grasping the main body with one hand and pulling the outer lid outward with the other hand, It is necessary to disengage the projection from the main circular hole. However, when the user usually wants to listen to the CD, it may not be possible to use both hands at the same time, for example, while driving, so open the CD case with one hand like this. It was inconvenient not to do it.

Further, the well-known CD case is considerably different from a new one that has been used for a certain period of time, and the one that has just been purchased has a relatively good degree of closeness, which makes it difficult to open, but it has been used for a certain period of time. Then, when the connection was loosened, it came to open automatically just by picking it up, causing the situation where the CD fell off and was damaged.

[0006]

[Problems to be solved by the device]

 An object of the present invention is to provide a CD case that can solve the above-mentioned drawbacks of the known CD case, that is, if a push button provided on the CD case is pressed with one hand, the protruding curve of the spring combined with the push button is provided. The part is released from the protruding part that locks the CD containing sheet, the CD containing sheet can be ejected by the elastic force of the spring piece to expose the CD, the CD containing sheet can be completely pulled out and positioned, and the CD can be taken out. The purpose of the present invention is to provide a CD case that has the convenient characteristic that a CD can be taken out with one hand.

A second object of the present invention is to store a CD accommodation sheet, if the CD accommodation sheet is simply pushed in, the protrusion is locked to the protruding curved portion of the spring to complete the storage, which is very convenient. It is to provide a practical and practical CD case.

Still another object of the present invention is that the push button is provided in a recess, the push button does not protrude from the upper lid, and therefore when the CD cases are stacked, the CD accommodating sheets are erroneous due to a collision. The purpose is to provide a CD case that will not be ejected.
