Description: This invention relates to an improved compact disk carrying container. It has been found that the conventional compact disk carrying container as shown in figures 1a and 1b consists of an upper cover A, a lower cover B hingedly connected with the upper cover at one side, and a disk holder C fitted in the lower cover B. The upper cover is formed at both sides with a vertical side wall having a cavity A1. The lower cover B is formed at both sides with a protuberance B1 adapted to engage the cavity A1 of the upper cover A. The disk holder is formed with a retainer C1 at the center for keeping a compact disk in place. However, such a compact disk carrying container has the following drawbacks: 1. Three molds are required for manufacture thereby increasing the manufacturing cost. 2. It is not easy to open. 3. It is often confusing as to finding out the correct direction to open the compact disk carrying container. 4. The hinge connection between the upper cover A and the lower cover B is so weak that it will be easily broken when dropping down on the ground. 5. It is necessary to prepare a cabinet for storing the compact disk carrying containers hence increasing the burden to the user. WO-A-92 22903 shows another prior art of a compact disc carrying container comprising an upper cover with a left and a right side wall formed with grooves and flanges and a lower cover with a left and a right side, formed with grooves and flanges, which flanges c2 are adapted for sliding in the grooves of the upper cover. A similar kind with same function is shown in the prior art figures 2 and 3a-c of the current application with flanges b2 and c2 on the side walls of the upper and lower cover. And further the upper cover comprises a recess at one end and the lower cover is having a protuberance adapted to engage the recess of the upper cover. A retainer for keeping a compact disc in place is formed in the centre of the lower cover. Each container can have a number of small protrusions engageable into recesses on an neighbouring container to get some kind of CD Box. It is, therefore, an object of the present invention to provide an improved compact disk carrying container which can obviate and mitigate the above-mentioned drawbacks. This invention relates to an improved compact disk carrying container. It is a primary object of the present invention to provide a compact disk carrying container which can be conveniently connected with a plurality compact disk carrying containers as desired. It is the another object of the present invention to provide a compact disk carrying container which is simple in container.

With reference to the drawings and in particular to FIGS. 4 thereof, the compact disc carrying container according to the present invention mainly comprises an upper cover 10 and a lower cover 20. As shown in FIGS. 4, 5A, 5B, 5C, 5D and 5E, the upper cover 10 is formed with a left side and a right side walls 14 each formed with a plurality of inwardly extending flanges 141 at the lower edge. Each of the side wall 14 has a recess 17 close to the rear end. An elongated member 13 which is parallel to the side wall 14 depends downwardly from the bottom surface of the upper cover 10. Between the elongated protuberance 13 and the side wall 14 there are a plurality of slots 15. The rear side of the upper cover 10 is formed with two elongated portions 19 and curved recess 12 between the two elongated portions 19. Each of the elongated portions 19 extends to connect with the corresponding elongated member 13. The front side 11 of the upper cover 10 has two vertical key slots 16 at both ends and a curved portion 111 protruding inward at the intermediate portion. The curved portion 111 is formed with a curved groove 112. The vertical key slot 16 is formed an enlarged portion 161 at the lower end. Between the slot 16 and the side wall 14 there is a notch 142. The upper cover 10 is further provided with two projections 18 on the top thereof. Referring to FIGS. 4, 6A, 6B, 6C, 6D and 6E, the lower cover 20 is provided at the center with a retainer C1 for keeping a compact disk in place. The lower cover 20 includes a left side, a right side, a rear side 21, and a front side 27. The left and right sides of the lower cover 20 are formed with two spaced racks 25 which are aligned with each other. Each of the racks 25 is formed with an upper groove and a lower groove 253 which are parallel to each other. On the upper groove 253 there are two projections 251 at two ends. The front side of the lower cover 20 has two vertical key slots 26 which are in alignment with the vertical key slots 16 of the upper cover 10. At the intermediate portion of the front side of the lower cover 20 there is a curved recess 22 which is adapted to receive the curved portion 112 of the upper cover 10. A partition composed of ribs 24 and 23 is formed just behind the front side of the lower cover 20. The intermediate portion of the rear side 21 of the lower cover 20 has a curved portion 211 which protrudes inward and adapts to be received in the curved recess 12 of the upper cover 10. The curved portion 211 is formed with a curved cavity 212 having two openings 213 adapted to engage two hooks 2141 of a handle 214 (see FIG. 7C). When the upper cover 10 and the lower cover 20 are fitted together, the flange 141 of the upper cover 10 is adapted to the lower groove 254 of the lower cover 20 while the projections 17 are slidably engaged with the upper groove 253 of the lower cover 20 thereby enabling the upper cover 10 to slide with respect to the lower cover 20. As the upper cover 10 is pushed to close the lower cover 20, the projections 17 of the upper cover 10 will be engaged with the projections 251 of the lower cover 20 so that the upper cover 10 will be firmly engaged with the lower cover 20 hence preventing it from being inadvertently opened. A securing bolt 40 with a flange 42 and a head portion 41 is snugly fitted into the vertical slot of the container (see FIGS. 9A and 9B). The flange 42 is adapted to the enlarged portion 161 of the vertical slot 16 of the upper cover 10 while the head portion 41 fitted into the vertical slot 26 of the lower cover 20. Further, the bottom of the securing bolt 40 is formed with a threaded hole 44 at the center so that the bottom of a securing bolt 40 can be engaged with the threaded rod portion 43 of another securing bolt 40 thus enabling a plurality of the containers to be connected together. When desired to remove a container, it is only necessary to pull the container out of the securing bolt 60 (see FIG. 10). Further, the containers can be conveniently connected in any desired arrangement such as those shown in FIGS. 11 and 12. The invention is naturally not limited in any sense to the particular features specified in the forgoing or to the details of the particular embodiment which has been chosen in order to illustrate the invention.
