Title: CD storage box

Description:
BACKGROUND OF THE INVENTION  
      1. Field of the invention  
      The present invention is related to a CD storage box, and especially to a CD storage box in which a stacking structure allows partial CD&#39;s to stack, thus the capacity for CD&#39;s can be increased.  
      2. Description of the Prior Art  
      CD&#39;s including CD&#39;s and VCD&#39;s generally are provided on the surfaces thereof with a data signal layer, to prevent the surfaces thereof from scrapping, such CD&#39;s generally are stored in a bag or a box. The advantage of using a storage box is that, CD&#39;s basically are positioned in a mode of separating from one another, the CD&#39;s in the box will not be scrapped frictionally even when they are shaken or carried on one&#39; person.  
      Conventionally, a CD storage box is composed of a lid and a bottom receiver in opposition to the lid; the lid and the bottom receiver can be closed to each other or can be separated from each other to reveal the CD&#39;s therein. In order to increase the receiving capacity of such a CD storage box, the lid and the bottom receiver generally are provided therein with receiving spaces of the sizes in corresponding to that of CD&#39;s to form a CD storage box of two CD&#39;s. Each receiving space has a central positioning post for slipping thereover a central hole of CD&#39;s; the CD&#39;s are fittingly positioned in the receiving space.  
      With the above structure, the CD storage box formed from the lid and the bottom receiver can receive therein two CD&#39;s in a mode of being stable and being not subjected to shaking and abrading. However, a box of quite a large volume only receives therein two CD&#39;s seems non-effective in capability, and thereby improvement is necessary.  
     SUMMARY OF THE INVENTION  
      The main object of the present invention is to provide a CD storage box; the body of the box can have larger CD receiving capacity therein.  
      To obtain the object, the box of the present invention integrally formed is provided with a plurality of mutually neighboring recesses in a recessed surface thereof, which recesses have their heights lowered from the first one gradually to the last one. Each recess has an annular chamber in corresponding by size to the diameter of a CD; the annular chambers each has a bottom surface with a predetermined radial width and an inner wall perpendicular to the bottom surface, and each is provided with a CD positioning means; each recess has a height different from those of its neighboring ones, part of their peripheries are mutually overlapped with a neighboring one as if the peripheries have notches.  
      The present invention will be apparent in its novelty and features after reading the detailed description of the preferred embodiment thereof in reference to the accompanying drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
      Referring to  FIGS. 1-3 , in the preferred embodiment shown, the present invention has an integrally formed (such as by vacuum forming) box  100 , the box  100  is provided with a plurality of mutually neighboring recesses in a recessed surface  101  thereof, which recesses have their heights lowered from the first one gradually to the last one. In the preferred embodiment shown, there are at least an outermost first recess  10 , a middle second recess  20  and an innermost third recess  30 .  
      The first recess  10  in the embodiment shown is an incomplete annular chamber, one side of the first recess  10  except those with a curve in corresponding with the size of a CD (i.e., the side at the left of the embodiment) and one neighboring side of the second recess  20  are mutually overlapped, this overlapping area is formed as a notch. The first recess  10  is composed of a bottom surface  11  with a predetermined radial width and an inner wall  12  perpendicular to the bottom surface  11 , and is provided with a CD positioning means. In the preferred embodiment, the positioning means includes a slightly raised arciform portion  13  at the junction of the bottom surface  11  and the inner wall  12  as well as a plurality of protruding strips  14  provided slightly higher than the raised arciform portion  13 . In the preferred embodiment shown, the inner wall  12  is provided with two sets of protruding strips  14  mutually opposite and separated; thereby the raised arciform portion  13  and the protruding strips  14  can form therebetween a positioning means in corresponding by size to the diameter of a CD. And for the convenience of moving and taking a CD stored in the first recess  10 , the outer side (i.e., the right side shown) of the first recess  10  is preferably provided on the periphery thereof with notches  35  for access of fingers to move the CD.  
      One peripheral side of the second recess  20  which is lower than the first recess  10  is partially stacked beneath the latter, the second recess  20  similarly is an annular chamber in corresponding by size to the diameter of a CD. In the preferred embodiment shown, the right side of the second recess  20  is partially stacked beneath the first recess  10 . The second recess  20  similarly is composed of a bottom surface  21  with a predetermined radial width and an inner wall  22  perpendicular to the bottom surface  21 , and is similarly provided with a CD positioning means including a slightly raised arciform portion  23  at the junction of the bottom surface  21  and the inner wall  22  as well as a plurality of protruding strips  24  provided slightly higher than the raised arciform portion  23 . The other side of the second recess  20  (namely the left side shown) partially overlaps the neighboring third recess  30 , so that both the left and right sides of the second recess  20  are formed notches.  
      The third recess  30  is more lower than a neighboring right side of the second recess  20  and is stacked beneath the latter to form an area as a notch; an annular chamber formed from it similarly is composed of a bottom surface  31  with a predetermined radial width and an inner wall  32  perpendicular to the bottom surface  31 , and is similarly provided with a CD positioning means including a slightly raised arciform portion  33  at the junction of the bottom surface  3   1  and the inner wall  32  as well as a plurality of protruding strips  34  provided slightly higher than the raised arciform portion  33 .  
      As shown in  FIGS. 4 and 5 , the outermost first recess  10 , the middle second recess  20  and the innermost third recess  30  can thereby be placed therein respectively with CD&#39;s  91 ,  92  and  93 . The CD&#39;s  91 ,  92  and  93  are firmly positioned by partially engaging on the means formed from the raised arciform portions  13 ,  23 ,  33  and the protruding strips  14 ,  24  and  34 . When it is desired to take out the stored CD&#39;s  91 ,  92  and  93 , as shown in  FIG. 6 , a thumb in cooperation with some other finger of a hand  90  can pick the CD&#39;s  91 ,  92  and  93  out from one side.  
      The above stated structure of the present invention can be used to more firmly position more CD&#39;s under the condition of being given with a CD storage box having an identical volume to a conventional box; this can breakthrough the limited capacity of a conventional CD storage box with CD&#39;s parallelly disposed therein. Having thus described my invention having high industrial value, what I claim as new and desire to be secured by Letters Patent of the United States are:  
      The preferred embodiments cited above are only for illustrating, and not for giving any limitation to the scope of the present invention. It will be apparent to those skilled in this art that various modifications or changes made to the present invention without departing from the spirit shall fall within the scope of the appended claims.
