Description
FIELD OF THE INVENTION

The present invention relates to container or case for holding a CD or DVD disc for storage or transporting purposes. References to disc in the specification generally refers to CD and DVD discs but is not limited to these disc types.


BACKGROUND OF THE INVENTION

With the development of information technology, discs have increasingly been used because of their ability to store large amounts of information.


The discs are stored in plastic cases often referred to as jewel cases. Each jewel case is generally made of two plastic parts that are hinged together. One part contains a central boss to receive the disc through the central hole of the disc while the other part of the jewel case forms a lid to enclose the disc within the jewel case. Jewel cases that can accommodate multiple discs have additional parts to hold more discs in place. The assembly of multiple parts of a jewel case adds to the complexity and costs of manufacturing the final product.


With collection of discs, storage of the discs in their individual jewel cases becomes impractical due to space limitations in office and homes. Another way of storing discs has been the use of purpose designed paper envelopes with a clear face that have been developed to hold discs and prevent them from being scratched. A further alternative has been the development of cardboard holders where the design of some of these cardboard holders are of the type that can open like a book and have pockets on each side. The use of paper envelopes and cardboard folders allow discs to be stored in a more compact manner. Whilst addressing the problem of limited storage space in offices and homes, paper envelopes and cardboard folders can be easily bent and therefore do not provide sufficient protection to the discs. Furthermore, each disc cannot be conveniently displayed in a paper envelope or cardboard folder.


OBJECT OF THE INVENTION

It is an object of the present invention to provide a disc case for a disc that overcomes in part at least one or more of the above mentioned disadvantages.


SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIGS. 1 to 4, there is shown a one-piece or integral disc case 10 for holding a CD or DVD disc. The disc case 10 has two preferably continuous or integral portions 12, 14 that are separated by a common fold-line 16. The two portions 12, 14 are the same shape and size forming a disc case that is symmetrical about the fold-line 16. The two portions 12, 14 have a substantially triangular shape with the apex of the triangle furthest from the fold-line 16.


The fold-line 16 is located in the centre of the disc case 10. The fold-line 16 enables one portion to move relative to the other by pivoting about the fold-line 16. This allows the two portions 12, 14 to move from an opened position as shown in FIG. 1 to a closed position as shown in FIG. 4.


Each portion 12, 14 has one folded pocket 18, 20 respectively for holding a disc 22 which can be a CD or DVD. The folded pocked is sub-divided by a longitudinal slit formed from edges of the sheet. Each folded pocket 18, 20 has an optional boss 21 that engages with the central hole of the disc 22 to retain the disc 22 within the pocket 18, 20. The boss 21 is designed so that the disc 22 can snap-fit onto the boss 21. The first preferred embodiment of the disc case 10 has a retainer flap 23 that can engage and retain an exposed section of the disc 22 when it is positioned within a pocket 18, 20. The retainer flap 23 can be formed as a cut-out from each portion or a protrusion extending from each portion. The retainer flap 23 is preferably position adjacent the fold-line 16.


Another embodiment may not have the retainer flap relying on the boss to position and hold the disc within the pocket.


A further embodiment may have side portions that upon closure of the disc case, fold inwardly to overlap the exposed section of the position disc to prevent the disc from accidental removal from the pocket.


When the disc case 10 is open, the pockets 18, 20 are on the same side of the disc case 10 as shown in FIG. 1. When the disc case 10 is opened, the pockets 18, 20 substantially oppose each other and a disc 22 can be inserted or removed from the each of the pockets 18, 20. When the disc case 10 is closed, the pockets 18, 20 are folded about the fold-line 16 to be on top of each other and be no longer accessible. The discs are stored away in the closed position. As each pocket 18, 20 sits flat against each portion 12, 14, the disc case 10 is less bulky compared with jewel cases. This allows more disc cases to be stacked one upon another to provide an efficient method for storing the discs where space is limiting.


The fold-line 16 of disc case 10 enables each portion 12 or 14 to be moved 180 degrees relative to the other portion 12 or 14. This allows the two portions to be placed in a standing position as shown in FIG. 2 for displaying the discs 22 and in FIG. 3 in the substantially closed position. Each of the portions 12, 14 are supported in a standing position by a support portion 30 located at the apex of the portion 12, 14. Each support portion 30 is a small triangular section defined by a fold-line 32 along its base. The support portions 30 also serve to maintain the disc case 10 in a closed position by folding one support portion backwards and folding another support portion forwards to overlay the backwards folded support portion.


The disc case 10 is made of a flexible plastic material that can protect the stored discs from being bent and damaged. The disc case 10 is preferably formed as a one-piece item and the boss 21 is formed from integrally and continuously the same plastic, paper or composite substrate textile sheet material as the case.


The disc case can be made in other shapes. For example, the two pockets may be two semi-circles and the support portions can be semi-circular in shape. Each pocket of the preferred embodiment, shown in the figures, can cover at least half of the disc when the disc is positioned within the pocket. However, a pocket may be able to cover more than half of the disc providing the opening of the cover is not less than the diameter of the disc.


In FIGS. 5 to 7, there is shown a multi-stack disc case 40 having two portions 41, 42 with a plurality of pockets 43 on each portion 41, 42. The disc case 40 has a fold-line 44 separating the portions 41, 42. Like the first embodiment, each portion 41, 42 can fold about the fold-line 44 to open and close the disc case 40.


Each portion 41, 42 has a substantially triangular section 45 and a rectangular section 46. The length of the rectangular section 46 depends on the number of pockets 43. Where there are more triangular pockets 43, the rectangular section 42 will be longer.


Each of the pockets 43 has a boss 48 for engaging and retaining the disc 49. Each pocket 43 overlaps an adjacent pocket 43 so that the discs 49 are retained in the pockets 43 where one disc 49 is slightly offset from another disc 49. This allows multiple discs to be stored in a single disc case. This provides a very effective method of storing discs where space is limited.


Like the first preferred embodiment, there is a triangular support portion 51 associated with each portion 41, 42 that can support the disc case 40 in an upright position and also serve as a closure when the disc case 40 is closed.


In FIGS. 8 to 12, there is shown a third preferred embodiment of a disc case 60. The disc case 60 is a one-piece disc case with two portions 61, 62 that are separated by a fold line 63. Each portion includes a folded pocket for a disc. The folded pocked is sub-divided by a longitudinal slit formed from edges of the sheet. The disc case 60 is similar to the disc case 10 described above except that the disc case 60 has four side sections 65, 66, 67, 68 that are inwardly foldable to overlie the internal surface of the portions 61, 62 when the disc case 60 is closed. The side sections forming two opposing lateral pleats 65, 67 and 66, 68. Each pleat e.g. 65 with 67 or 66 with 68 serves to secure one side of one or both adjacent discs 70, 71 within its respective pocket 72, 73. The side sections 65, 66 work together and fold inwardly and cover the exposed section of one disc 70 in the pocket 72 to substantially prevent dislodgement or loss of the disc 70 when the disc case 60 is closed. The side sections 67, 68 perform the same function as the corresponding and symmetrical side portions 65, 66. When the side sections 65, 6667, 68 are folded inwardly, each of the portions 61, 62 is hexagonal in shape.


In further embodiment, not shown in the figures, there may be a boss (as previously described) on each of the portions 61, 62 (in addition to side sections 65, 66, 6768) to hold a disc within the pocket.


As suggested in FIG. 11, each portion 61, 62 has a free end 75, 76 that is foldable along end fold-lines 74, 79. The foldable free end 75 on portion 61 can be folded over the outer surface 77 of the opposed portion 62 to maintain the disc case 60 in a closed position. The foldable free end 75 serves as a closure and can be held in a slit 78 formed in a portion 62.


There is preferably an aperture 80, 81 in each of the free ends 75, 76. When the free ends 75, 76 are not folded, a security chain 82 can be passed through the apertures 80, 81 e.g. to chain the disc case 60 to several other disc cases.


In FIGS. 13 and 14, there is shown a fourth preferred embodiment of a disc case 90. The disc case 90 is a one-piece disc case with two portions 91, 92 that are separated by a fold line 93. The disc case 90 is similar to the disc case 60 described above except that on one portion 91 of the disc case 90 there are two studs 95, 96 that can be passed through two stud apertures 97, 98 respectively located in the opposed portion 92. The studs 95, 96 and stud apertures 97, 98 serve as a closure to maintain the disc case 90 in a closed position. The lip 99, 100 of each std 95, 96 respectively substantially prevents inadvertent withdrawal or dislodgement of the studs form the stud apertures. In another embodiment the stud apertures may be recesses and the studs are snap-fitted within the recesses.


A blank 150 for forming a case according to the teachings of the present invention is depicted, in plan view, in FIG. 15. The blank may be used to form a case similar to the ones depicted in FIGS. 8-14. The blank is preferably formed by a semi-rigid board or other textile or polymer sheet approximately 31 cm long and about 21.5 cm wide. One corner 151 of the blank has been cut back or bevelled so as to form one half of the flap and medial slit 152 shown in FIG. 8. The corner of the other side 153 has a fold line 154 that is a mirror image of the cut corner line 151. The blank has a tab 155 with truncated corners 156 that protrudes beyond the fold line 154. As shown better in FIG. 8, a tab 155 extends beneath the retention flap 157 and the two adjacent retention flaps 157, 158 are held together and closed by a small adhesive fastener 159. A similar arrangement of retention flaps and tab 160, 161, 162 are located in the lower half of the blank 150. The two halves are separated by a central transverse fold line 163. Again with reference to FIGS. 8 and 15, it can be seen that an external edge 165 of a disc pocket is defined by a fold line 166 that extends from a notch 167 to a central lateral point 168. The part of the fold line 166 that extends beyond the external edge 165 forms a fold line in a complex of lateral pleats 170 that correspond to the symmetrical side portions 65, 66 discussed above. The pleats fold inwardly to produce the type of structure seen in FIG. 9. The blank 150 also includes a peak flap 180 that may be utilised, as, for example, the foldable free end 75 seen in FIG. 8 or folded and tucked under the disc retention flaps as shown in the lower half of FIG. 8. Thus, the upper and lower edges of the blank are characterised by triangular notches 167, located to either side of the longitudinal centre line and define edges of the flap 180. Thus, it will be appreciated that the blank depicted in FIG. 15 is adapted to produce a case for two discs that when folded, form the finished hexagonal case shape depicted, for example, in the embodiments suggested by FIGS. 8-14. It will be appreciated that each of the external edges of the final hexagonal shape are defined by fold lines, e.g. 166, 163 and that these same fold lines contribute to the formation of the various flaps and pleats that are used in the fabrication of the case. In the example depicted in FIG. 15, only the peripheral edges of the blank are cut and no cutting is required apart form these, excluding the optional slit 78 depicted in FIG. 11. It will also be appreciated that there is considerable latitude in the configuration of the size and shape of the peak flap 180 and the optional tabs 155, 162.
