 (a) Field of the Invention
 The present invention relates to an improved structure of a CD storage device comprising a plurality of thick paperboard sheets so as to store large amount of CDs. The surface of each thick paperboard sheet is provided with sealed storage chamber for the storing of CDs. The device allows convenient withdrawal and insertion of CDs, and the device can be manufactured with low cost, and it requires a small space to be stored.
 (b) Description of the Prior Art
 Conventional CD storage boxes normally made from plastic material or acrylic material, as shown in FIG. 1, for storing of CDs. As plastic material is rather soft and thus the plastic CD boxes may not be able to well protect the CDs, and the CDs may be scratched or damaged. In addition, these storage boxes may not be easily kept, i.e. a larger space is needed for storage, and the retention member at the center of the storage compartment of the storage box does not allow a quick withdrawal of the CD. Thus, this conventional CD storage boxes have the drawbacks of storage problems and a limitation in storing great number of CDs.
 Another conventional CD storage device is a book-like structure and is shown in FIG. 2. In this conventional structure, a plurality of engaging CD members having the structure as that of the above-mentioned CD storage box are used to form into a bound volume. Similarly, the withdrawal of CD therefrom is rather troublesome. Besides, the different types of material for each device used in the manufacturing process causes an increase of production cost.
 Thus an object of the present invention is to provide an improved structure of a CD storage device, which mitigates the drawbacks found in the conventional CD storage boxes.
 Accordingly, it is an object of the present invention to provide an improved structure of a CD storage device, characterized in that a plurality of storage chambers are provided to every sheet of the paper board and the circumferential edge of the storage chamber is provided with a covering plate to prevent the CD from dislocating therefrom, and a notch allowing convenient withdrawal of the CD, thereby the CD storage device provides convenient and a practical storage of CDs.
 Yet another object of the present invention to provide an improved structure of a CD storage device, wherein the thick paper board comprises a hard board and a paper board formed as a unit which is foldable, and a thin paper sheet is located between the hard board and the paper board, and the center of the hard board and the paper board is provided with score-line and strap-like slot, facilitating the formation of the hard paper board sheet.
 The foregoing objects and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.
 Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
 For the purpose of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings. Specific language will be used to describe same. It will, nevertheless, be understood that no limitation of the scope of the invention is thereby intended, alterations and further modifications in the illustrated device, and further applications of the principles of the invention as illustrated herein being contemplated as would normally occur to one skilled in the art to which the invention relates.
 Referring to FIG. 6, there is shown an improved structure for a CD storage device, comprising a plurality of thick paper board sheets 10, and the surface of each sheet 10 is provided with a set of sealed storage chamber 14 with a notch allowing the insertion of CDs.
 Referring to FIGS. 3 to 5, in the process of making the thick paper sheets 10, hard board 11, shown in FIGS. 3 and 4, is used to combination with a paperboard 12 by gluing them together. As shown in FIG. 3, the hard board 11 is cut into rectangular shape and a score-line 111 having notches 112 at the two ends thereof is formed. The hard board 11 is divided into a foldable left and right section. At the same time, a center hollow circular recess 113 is formed at the left and right section of the hard board 11.
 A covering plate 114 and a recessed chamber 115 are formed at the diagonal corner of the circular recess 113. In addition, an elongated through hole 116 is formed at the left and right section of the folded hard board 11, closer to the corresponding external edge thereof. As shown in FIG. 3, the paperboard 12 is rectangular shape, and the center thereof is a strap-like slot, corresponding to the score-line, and the two ends of the strap-like slot 121 are kept a distance away from the edge thereof, and this distance equals to the distance of the notch 112 at two ends of the score-line 111. On the paperboard 12, there are two circular hollow recesses 122 and notches 123, and an elongated through hole 124 is formed close to the two lateral edge thereof.
 An adhesive is used to glue the hard board 11 with the paperboard 12 to form as a unit, which is shown as thick paperboard sheet 10 in FIG. 4. This sheet 10 is foldable and a thin sheet 13 is inserted corresponding to the internal of the paperboard 12, and glue is used to adhere them together as a unit.
 The excess portion, beyond the score-line 111, and the through holes 116, 124, is cut-off such that the paperboard, located at the outer edge of the through holes 116, 124, is formed into a binding section 125. The slot 116 of the hard board 11 and the slot 122 of the corresponding paperboard 12 together with the thin paper 13 to form a storage chamber 14 for adaptation of CDs 2.
 In view of the above, and in application, a plurality of thick paper board sheets 10 are employed and a sealing sheet 15 covers one end of the sheets to form a bound book-like storage device for CDs. Thus, the structure containing the CDs can be browsed as a book, which is shown in FIG. 6.
 In application, a plurality of CDs are inserted onto the storage chambers 14 of the thick paperboard sheet and the covering plate 14 is used to prevent the dislocation of the CDs. When withdrawing the CD 2, a finger can be placed at the notch 115 and after the CD is withdrawn, the device can be covered with an outer covering box.
 As shown in FIG. 7, a plurality of removable thick paperboard sheets 10 are used to contain a plurality of CDs 2.
 Referring to FIGS. 8A, 8B, 8C, 9 and 10, the thick paper board sheet 10 can be modified to simplify the manufacture. As shown in FIGS. 8A, 8B and 8C, the first and the last hard boards 11 are formed with only one circular recess 113 with a covering plate 114, while the hard boards 11 between the first and last hard boards 11 are formed with two circular recesses 113 each with a covering plate 114. As shown in FIG. 9, the paperboards 12 and the thin sheet 13 between the first and last hard boards 11 are only one half of the hard boards 11 in area and are joined together by adhesive. The paperboard 12 is also formed with a circular recess 122 aligned with the circular recess 113 of the hard board 11. FIG. 10 is a perspective view of a compact CD storage structure.
 It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
 While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
