Description

FIELD OF THE INVENTION

The present invention relates to a media storage disk box such as for example those commonly used in the storage of CD Roms, DVDs, music CDs or similar.

BACKGROUND

A box or case to retain a CD or DVD are the common form by which such goods are normally sold. A box has the ability to carry product information and advertising whilst simultaneously providing protection to the disk. In a normal form of such a box the box consists of a base panel and a cover panel which are movable relative to each other. The configuration is of a kind to provide a wallet like enclosure within which a disk can be stored. Such a box or case will also normally include a mounting region with which a disk can be mounted. The movement of the base and cover panels can be such as to provide an enclosure to securely locate the disk within the enclosure yet allow for the cover to move relative to the base and allow for access to be gained to the enclosure to allow for the removal of the disk from the box. In the most common form the box itself does not present the product branding, advertising and product information. Normally a paper sleeve is engaged with the box, the paper sleeve providing such indicia. Accordingly the boxes which are manufactured to carry the disks are normally of a generic kind and the boxes are customised by the engagement of a paper sleeve carrying the graphics and indicia corresponding to the disk which is to be retained within the box. Besides appropriate selection of the indicia or graphics provided by a paper sleeve, no real significant other ways of distinguishing the box from other boxes is able to be achieved. The paper sleeve is normally that portion which is the most obvious means of drawing attention to the box but beyond the selection of colours and graphic styles, no other differentiating features are conveniently incorporated with known boxes. In a consumer market to which DVDs and CDs are directed, it is important to allow for distinguishing features to be provided by the box to attract a consumer and encourage them to purchase that particular product. There has accordingly been a need to provide different forms of visual appeal for DVD or CD to be boxed for such purposes.

Accordingly the present invention is directed to a media storage disk box which provides a different visual appeal visible from exterior of the box to those boxes as hereinbefore described or to at least provide the public with a useful choice

DETAILED DESCRIPTION OF THE INVENTION

With reference to FIG. 1, the box may generally be defined by a unitarily formed plastic body [0101] 1 which consists of first panel 2 and a second panel 3. The first and second panels are generally planar panels however relief details are or can be provided thereto. The first and second panels are preferably of a complimentary size and shape such that when they are in an overlapping condition (a box closed condition) the perimeter of the first and second panels are commensurate with each other. The first and second panels are connected to each other via a hinge 4. The hinge 4 is for example a hinge panel which (being integrally formed with the first and second panels 2, 3) is positioned intermediate of the first and second panels 2, 3. The hinge 4 may define axes of rotation XX and YY which allows for each of the first and second panels 2, 3 to move relative to the hinge panel 4 and relative to each other. In the most preferred form and with reference to FIG. 1, the unitary plastic body 1 provides the two hinges intermediate of the hinge panel 4 and a respective first and second panel 2, 3. The axes of rotation XX and YY are provided as a consequence of a change in the wall thickness of the unitary plastic body 1. Such a change in the wall thickness where the thickness is reduced, provides a region about which the components of the unitary plastic body can rotate relative to each other. In an alternative form of the present invention it may be that the hinge 4 defines merely one axis of rotation being an axis of rotation to allow for mutual rotation of the first and second panels 2, 3 relative to each other. The hinge itself may in such a configuration form part of the first and second panels of the unitary plastic body 1. However in the most preferred form the hinge 4 is a separate panel to the first and second panels 2, 3 and as such provides a spine or at least part of a spine to the box. The first and second panels 2, 3 are each independently movable relative to the spine provided by the hinge according to the configuration of FIG. 1.
In the most preferred form the first and second panels are in plan shape of a quadrilateral perimeter. As can be seen in FIG. 1 the box is in a substantial part defined by the first and second panels which are of a rectangular perimeter shape. The spine is provided intermediate of the first and second panels juxtaposed to two major sides of the rectangular form of each of the [0102] panels 2, 3. However in an alternative condition the spine may be provided along two of the minor sides of the rectangular perimeter form of each of the panels 2, 3. The relationship of the two panels 2, 3 is such that by rotation about the pivot axis or axes XX, YY, the perimeter regions of each of the two panels 2, 3 become engaged with each other to define within the perimeter and within the major surfaces of the panels 2, 3 and enclosure. With reference to FIG. 8, the box is shown in a closed condition.
The [0103] first panel 2 has provided on the enclosure facing side thereof a disk mounting region 7. The disk mounting region 7 may include disk peripheral relief 8 and also include a mounting means 9 which is for example a rosette style mounting to engage with the central aperture of a disk in a manner to be releasable therefrom. The enclosure side of the second panel 3 may include relief details such as clips 10 which may be provided for the purposes of releasably affixing to the enclosure side surface of the second panel, an information booklet.
Provided to at least one of the first and [0104] second panels 2, 3 and to the side thereof (opposite to the enclosure facing side), is a sheet metal cover 12. The sheet metal cover 12 is preferably co-extensive with the non enclosure facing side of the plastic panel. The sheet metal cover as for example shown in FIG. 14B is also of a rectangular form and is affixed to one of the plastic panels 2 or 3. In the most preferred form both plastic panels 2, 3 have engaged to the non enclosure facing side thereof such as sheet metal cover. The sheet metal cover is affixed with the plastic panel in a manner to be permanently retained therewith. In the most preferred form the sheet metal cover also locates over at least a substantial part of the perimeter of each of the panels 2, 3. The sheet metal cover is preferably substantially planar as far as its location adjacent the major surface of the plastic panel 2 or 3, but includes perimeter upstanding wall sections 13 which locate about corresponding upstanding walls 15 of the perimeter of the plastic panel 2, 3. As such, the perimeter upstanding wall sections 13 of the sheet metal covers enclose about a substantial part of the exterior to the enclosure directed surfaces of each of the plastic panels 2, 3. Upstanding walls 15 are however preferably not provided by the plastic panels 2, 3 at the region where the plastic panels are juxtaposed with the spine or hinge 4. As a consequence and likewise, no upstanding perimeter wall sections 13 of the sheet metal panels are provided in regions corresponding to such juxtaposed to the spine regions of the plastic panels. It is indeed as a consequence of the upstanding wall sections 13 of the sheet metal panels by which the sheet metal panels become engaged and affixed to a respective plastic panel 2, 3. With reference to FIG. 14B the upstanding peripheral wall upstands 13 of a sheet metal panel extend at least in part about the perimeter of the sheet metal panel at each of the four sides thereof. As can be seen in FIG. 14B such peripheral upstanding wall sections 13 are not provided to the sheet metal panel at region 18 being the region corresponding to where the sheet metal cover is provided adjacent the spine 4. However short sections at the end of each of the ends of that edge at where the spine is provided (e.g. the ends 19) such upstanding wall sections are provided. As can be seen in FIG. 2, the spine 4 is not of a length equal to the major side length of the rectangular shaped plastic panels 2, 3. Indeed the spine 4 is of a length shorter than the major sides of the panel such as to allow for the end regions 19 of such a major side to be free from engagement with the spine 4.
Each of the sheet metal covers at its upstanding peripheral wall includes a [0105] flange downturn 20. The flange downturn is an extension from the upstanding peripheral wall 13 which is directed both inwardly and downwardly back towards the major panel of the metal cover 12. As a result a radiused surface 21 is presented defining the distal edge of the upstanding wall 13. Such a downturn is provided for both providing a safe and non-dangerous finish to the sheet metal panel but also to provide a clipping feature to allow for the sheet metal cover to clip with a respective plastic panel. With reference to FIG. 10, corresponding clipping relief 22 is provided to the exterior side of the upstanding wall 15 of the panel 2. Such clipping relief 22 presents a surface with which the downturn 20 can engage. In a most preferred form a plurality of such clipping relief features 22 are provided about the perimeter of the upstanding wall 15 of the panel 2 and also for example from the panel 3. Adhesive may in addition or alternatively be used.
As can be seen with reference to FIG. 10, [0106] such clipping relief 22 is provided below the free edge 26 of the upstanding walls 15 of the panel 2. With reference to FIG. 8, the complimentary free edges 26 and 27 of the first and second panels 2, 3 are capable of engaging with each other when the box is in the closed condition. Accordingly there is no contact that occurs between the sheet metal covers of the first and second panels when the box is in the closed condition and it is the free edges of the upstanding walls 15 of the plastic panels 2, 3 which engage with each other. Provided to the plastic covers may be detailing 28 and 29 provided for the purposes of allowing for the box in the closed condition to be locked in the closed condition. The closure features 28 and 29 are preferably locking components which interact with each other to hold the box in the closed condition yet allow for the box to be opened when desired. A tongue and groove-like arrangement for the closure features 28 and 29 as for example shown in FIG. 5 may be utilised. A handled or handle region 30 and 31 may be provided to each of the first and second plastic panels 2, 3. Such a handle region 30, 31 is preferably provided to allow for the box to be grasped by a person and to allow for the first and second panels to be moved from the closed condition to the locked condition. The handled region may provide surface indents within which fingers can be positioned to allow for the box to be opened.
In the configuration of the box where a [0107] separate spine panel 4 is provided a sheet metal spine cover 35 may be located. With reference to FIG. 15 such a sheet metal spine cover 35 is preferably of a length to cover the entire length of the spine panel 4. It is preferably also of a width covering a substantial portion of the spine panel. The sheet metal spine cover 35 is engaged with the spine 4 to the non enclosure facing side thereof. Clipping tabs 36 are provided at each end of the sheet metal spine cover 35 and such tabs can be folded to locate the sheet metal spine cover to the spine 4. With reference to FIG. 1, the tabs 36 are shown in an unfolded state. The enclosure facing side of the spine may include regions 38 which provide relief into which the tab 36 can be folded. Such relief may be a surface indent to the interior facing surface of the spine such that when the tab is folded over, it is located within the rebate or receptacle region defined on the interior surface of the spine 4. The tab 36 do not protrude out from such a receptacle region 38. As a consequence of such, the possibility of a snagging or catching of the tab 36 with a foreign body can be avoided.
The plastic panel may also include and presented beyond the [0108] free edge 26 and/or 27 of at least the first panel 2 and possibly also the second panel 3, upstands 40. The upstands 40 are provided to locate to the interior side of the upstanding wall 15 of the other panel and to locate against the inwardly directed surface of such upstanding wall 15 of the other panel to thereby provide resistance to the sliding movement of the two panels relative to each other. Whilst resistance to such sliding movement is provided as a result of the integral formation of the two panels incorporating the hinge, because the plastic material is of a flexible nature the upstands 40 (in a direction parallel to the substantially planar configuration of the box in its closed condition) will resist the sliding movement. In a preferred form of the invention it is only one of the panels 2, 3 which provide such upstands and these may be provided in a form where there are a plurality of such upstands provided about the perimeter of the first or second panels 2, 3 or may alternatively be a continuous or semi-continuous edge or lip presented from the free edge 26 of the panel 2 or the free edge 27 of the panel 3.
The metal covers are made form a metal which can provide high gloss characteristics. The metal covers may be printed with a printing ink to provide graphics and product information to the exterior side of the box. The fact that such printing inks are provided to the exterior of the metal covers can allow for the high gloss character to be taken advantage of. A metallic finish can be obtained. Furthermore, the sheet metal may, during its forming procedure, have provided regions of embossing to the major panel regions thereof. The embossing can provide further enhancement especially where such is provided to define an outline enhancement to graphics subsequently printed there on. [0109]
