DETAILED DESCRIPTION OF THE INVENTION

The disc storage case 1 consists an upper closure member which resembles an upper clam shell half 3 and a lower closure member which resembles a lower clam shell half 5, linked or coupled together by a hinge 7. In the embodiment shown the hinge 7 is a live hinge providing two parallel pivot axes at two places, one on each of the vertices of the upper and lower clam shell halves respectively. However the hinge may also be just a single hinge point, and/or may be a clipped or pinned hinge common in that art.
The clam shell halves 3 and 5 articulate about the hinge 7 to form an enclosed space when the clam shells are in a closed condition as shown in FIG. 4. In the embodiment shown the clam shell halves 3 and 5 form an entirely closed internal space, however provided they sufficiently can contain the discs and prevent their damage and/or removal, various forms defining a skeletal enclosure are also within the scope of the invention.
A latch 9 is provided to depend from either the upper or lower clam shell half 3 and 5. As shown in FIG. 3, the latch 9 is pivotally mounted from the upper clam shell half 3. The pivoting is via two stubs 10 which the latch 9 engages to allow it to pivot from the closed position engaged on the lower clam shell half 5, to an open position whereby the storage case is free to open.
The latch 9 when closed secures to the lower clam shell half 5 via two catches 12 on the inner side of the latch 9. These catches 12 engage catch receiving apertures or other surface relief 14 on the front side face of the lower clam shell half 5. However, the catches 12 may be on the clam shell half to be engaged and the apertures 14 may be on the latch, or any other suitable latch closure mechanism may be used.
As shown in FIGS. 1-4 the catches 12 and apertures 14 co-operate when the latch 9 is closed against the lower clam shell half 5 to retain the two clam shell halves together. In other embodiments the catches 12 and apertures 14 may only hold the latch 9 closed and a further lip or other engagement means engages the clam shell half to keep the two halves together. In such an embodiment the catches 12 may engage apertures 14 on the clam shell half from which the latch 9 depends and the other engagement means will engage the other clam shell halves to ensure the storage case is closed.
In an open condition, as shown in FIG. 2, the disc or discs 11 can be located in the internal and exposed space. The central aperture of the disc(s) is located upon a retaining member 17 which depends from the inside of the lower clam shell half 5. The retaining member 17 may extend far enough to rest against the inner surface 4 of the upper clam shell half when the two halves are closed, thus preventing the discs from sliding off the retaining member 17.
Once the disc(s) 11 are loaded on the retaining member 17 a holding member 15 having an aperture 16 therein for receiving the retaining member may be located on the retaining member and pushed down against the disc(s), further preventing them from moving.
Referring to FIG. 3, the retaining member 17 may have at least one, and preferably two rows of diametrically opposed teeth 19. Complimentary engaging teeth or surface relief 20 may also be provided on the periphery of the aperture 16 of the holding member 15. The holding member 15 has zones of weakening 22 (shown in FIG. 12) at or near the complimentary engaging teeth 20, such that to apply the holding member 15 to the retaining member 17 the teeth 20 ratchet down the row of teeth 19, but strongly engage the teeth 19 such that to remove the holding member 15 from the retaining member 17 the teeth 20 must be broken or at least bent. This provides a physical and visual indication of removal of the holding member 15 and possible tampering with the discs 11. The holding member 15 may have upward angled edges to enable easy grasping and removal by a user.
Referring to FIG. 5, once the discs are loaded into the storage case and retained therein by the retaining member 17 and the holding member 15 the clam shell halves are closed and the latch 9 is brought to engage the lower clam shell half 5, closing the storage case 1.
Referring to FIGS. 6 and 7, a tamper evident locking device 13 can then be installed. The tamper evident locking device 13 includes a head portion 27, which may be larger than the locking shaft portion 29, which depends therefrom. The head portion 27 serves the function of retaining the tamper evident locking device 13 against the latch 9 and also serves to provide a location 28 for later engagement with a tool or object 35 when the locking device 13 is to be removed. The tamper evident locking device 13 maintains the latch 9 against either or both of the adjacent clam shell halves, in a latching condition.
The locking shaft portion 29 has along its length a frangible zone 33 and a catch portion 31 at its distal end. The locking shaft portion 29 is configured to engage a complimentary receiving aperture 32 in the clam shell half that the tamper evident locking device 13 is to engage. The frangible zone 33 is of sufficient weakness that the locking shaft portion 29, once engaged with the complimentary receiving aperture 32, cannot be disengaged, until the frangible zone 33 is fractured and the catch portion 31, with part of the locking shaft portion 29, is disengaged from the remainder of the locking device 13 and is retained in the aperture 32 to indicate tampering.
The catch portion 31, or a part of the locking shaft portion 29 that is retained in the receiving aperture 32, may be colour coded to visually indicate that there has been a tampering, such as the catch portion 31 being evident through a window 26 when the storage case 1 is opened.
The tamper evident locking device 13 once engaged through the latch 9 into the clam shell half indicates a closed and sealed disc storage case. The head portion 27, to prevent inadvertent fracturing of the frangible portion 33, may be at least partially recessed into the latch 9.
In one embodiment, in order to break the seal provided by the tamper evident locking device 13, it should be intentionally broken. This can be done with the engagement of the location 28 with a tool or object 35 (e.g. a coin, screw driver or other blade shaped device) and the head portion 27 rotated sufficiently to fracture the frangible portion 33. The catch portion 31 may, once inserted into the aperture 32, be prevented from rotating whilst other parts of the locking device can rotate. For example, the catch portion 31 may include one or more notches configured to engage one or more slots in the aperture 32, impairing rotation of the catch portion 31. In another embodiment, the head portion 27 may be threadingly engaged to the latch 9 and a rotation of the head portion 27 may cause a twist fracturing of the catch portion 31.
In yet another embodiment, the tamper evident locking device 13 can be broken by levering the device 13 itself with application of force directly to the head portion 27. This can be achieved by acting directly on the head portion 27 or by levering the latch 9 open sufficiently to fracture the zone 33.
The head portion 27 and part of the locking shaft portion then are free to be removed, allowing opening of the case by uncatching of the latch 9 and opening the clam shell halves, relative to each other, about the hinge 7.
Referring to FIG. 11, the discs may still not be removed from the retaining member 17 as the holding member 15 is still engaged therewith. Thus, the holding member 15 must be broken in order to remove it from the retaining member 17 to allow the discs 11 to be accessed.
The case can be reclosed at will by the user, but the tamper evident locking device 13 has been fractured. The complimentary receiving aperture 32 may permanently retain the fractured part of the tamper evident locking device 13 to prevent re-sealing by introduction of a new tamper evident locking device. Alternatively, the complimentary receiving aperture 32 can release the fractured part of the tamper evident locking device 13, to allow a resealing of the storage case 1 for multiple security uses.
Another embodiment of disc retaining members is shown in FIGS. 14 and 15, wherein a plurality of peripheral retaining members are arrayed to define a retention zone of a diameter generally equal to that of the discs to be stored. An array of three or more such peripheral retaining members 18, depending from the inner surface 6 of the lower clam shell half 5, will retain the discs 11. A downward holding member 24 of a disc like shape can engage similar teeth 20 on the peripheral retaining members 18 in a similar way to that of the holding member 15 and retaining member 17. While four peripheral retaining members are shown in FIGS. 14 and 15, any number may be used, for example, one or two retaining members. The retaining members may also be integrally incorporated into the inner walls of the case.
In one embodiment, the disc storage case is constructed from plastic or polymer materials. The disc storage case, except for the latch and the locking device, may, for example, be a single, integrally molded form. However, any other suitable materials and manufacturing techniques may be used. Any combination of materials may also be used.
The previous description of embodiments of the present invention is provided to enable a person of ordinary skill in the art to make or use the present invention. Various changes and modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments without departing from the spirit or scope the invention. For example, while certain shapes and characteristics of the latching and locking mechanisms have been described, other shapes and designs may be used without departing from the scope of the invention. Also, while the disc storage case is described having a generally clam-shell shape, any other suitable shapes and designs may be used. Also, the various embodiments described may be considered alone or in any desired combination. Accordingly, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and features disclosed herein.
