1. Field of the Invention
The present invention relates generally to a package for storing one or more Universal Media Disc™ cartridges and, more particularly, to a tray for supporting at least one Universal Media Disc™ cartridge and to a package for housing at least one UMD cartridge.
2. Description of the Related Art
The Universal Media Disc™ (UMD) is an optical disc recording medium currently capable of holding 1.8 gigabytes of data, such as games, movies or music. A UMD cartridge typically has a length of 65 mm, a width of 64 mm and a thickness of 4.2 mm. The UMD was developed by Sony for use on the PlayStation® Portable, which currently is the only playback device which supports the UMD format.
The UMD is commercially available as a disc cartridge that contains the optical disc recording medium, so as to protect the recording medium and to be loadable into a playback device.

The upper and lower halves 14, 16 have respective peripheral walls 42, 44 that extend respectively downward and upward to form an outer peripheral wall 46 of the cartridge main body 12 when the two halves 14, 16 are aligned and bonded to each other. As shown in
Typically, UMDs are packaged in trays having appropriately shaped receptacles for receiving the UMD cartridges. The UMD cartridges are held in the receptacles by a pair of resilient vertical tabs having protrusions extending from their upper ends into the receptacles above the cartridge. The cartridges are inserted axially into the receptacles, causing the resilient tabs to flex outwardly from their rest positions during insertion and to snap back to their rest positions after the cartridge moves downwardly past the protrusions. With a cartridge in the receptacle, the protrusions overlie the cartridge along its top arc-shaped part 20 and its lower continuously curved part 26. Finger wells are provided adjacent each of the lateral sides 22, 24. Thus, in order to insert a cartridge into or remove a cartridge from a receptacle, the user must grasp the UMD cartridges along their lateral sides 22, 24. In so doing, the fingers are very likely to touch and damage the exposed optical disc 18 through the head receiving aperture 38, which communicates with lateral side 24. Moreover, when grasping lateral sides 22, 24 and pulling upwardly to remove a cartridge from a receptacle, the user must pull upwardly with sufficient force to overcome the holding effect of the overlying protrusions. In so doing, the protrusion overlying the top arc-shaped part 20 of upper half 14 frequently catches on the lower half 16 along its top arc-shaped part, pulling the lower half 16 away from the top half 14 and sometimes damaging the cartridge 10.
It is, therefore, an object of the present invention to provide a tray and package for storing UMD cartridges in which the cartridges can be inserted and removed without subjecting the optical disc to damage by contact through the head receiving aperture. It is another object of the present invention to provide a tray and package for storing UMD cartridges which overcomes the tendency of the upper and lower halves of the cartridge to separate upon removal of a cartridge from a receptacle because the lower half catches on the overhanging protrusion of one of the retainer tabs. Efforts to date directed at such trays and packages suffer from one or more shortcomings which make the resulting packaging unsatisfactory. Accordingly, there remains a need for a simple, inexpensive to manufacture, inexpensive to ship and display package capable of storing one or more UMD cartridges, which is reliable for use over the long term.
In accordance with the invention, a package is provided, which includes a tray for holding one or more media cartridges. The tray includes a main body portion having one or more receptacles defined therein for accepting each of the one or more media cartridges. Each receptacle is contoured to substantially follow a contour of the one or more media cartridges, and includes at least one resilient latch defined in the wall of the tray, associated with each of the one or more receptacles. The at least one latch is configured and adapted to engage a first edge of a media cartridge. Optionally, the tray can include first and second opposed latches, the first and second latches being adapted and configured to engage opposite first and second edges of the media cartridge.
Further in accordance with the invention, a resilient tab can be defined in a bottom wall of at least one of the one or more receptacles for engaging a media disc held within a respective media cartridge. The tab is configured and adapted to urge a media disc within the media cartridge toward an opposite wall of the cartridge to protect an optical surface of the disc from damage. The resilient tab can be defined by a slit, which can be a substantially U-shaped slit, formed in a bottom wall of a receptacle and can include a protrusion at its distal end for contacting a portion of a media disc held with a media cartridge.
Two or more receptacles can be provided, being configured to receive media cartridges in an overlapping relationship. Each receptacle can include a bottom wall and a sidewall extending from the bottom wall, the bottom wall being provided with a stepped contour to define separate receptacles for each media cartridge and to facilitate overlapping of the cartridges. Additionally or alternatively, the bottom wall can be provided with one or more protrusions thereon, each being configured and adapted to closely match a contour of a media cartridge. If desired, the package can include any number of receptacles defined therein. For example, one, two, three, four, five, six or more receptacles can be provided in each tray. Further, depending on the embodiment, a plurality of receptacles can be defined within one or more larger receptacles.
Any desired cover can be provided in connection with packages in accordance with the invention. For example, a cover can include a hinge portion defining a lid portion thereof, for removably covering the tray. Alternatively or additionally, the cover can include a removable sleeve, for slideable engagement with the tray. Alternatively or additionally still, a tamper-evident overwrap can be applied around the tray, to prevent or inhibit damage to and/or theft of the media cartridges held therein.
One or more finger wells can be provided to enable grasping of a media cartridge by a user. Such well(s) can be defined along the contour of at least one of the one or more receptacles, along one edge of the receptacle, such as at a point intermediate the first and second latches.
In accordance with the invention, each latch can be defined by at least one slit provided in the side wall of the tray, which can be a substantially U-shaped slit. The latches can include a pawl extending from an upper end of each of each latch, for engaging an edge of an upper surface of a media cartridge, to inhibit removal of the cartridge from the tray. Alternatively or additionally, the latches can be configured and adapted to frictionally engage opposite sidewall edges of a media cartridge to inhibit removal of the cartridge(s) from the tray. Further, each latch can be provided with an aperture defined therein, configured in order to pre-select a bending resistance/resiliency of each latch.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and are intended to provide further explanation of the invention claimed.
So that those having ordinary skill in the art will better understand how to make and use the trays of the subject invention, embodiments thereof will be described with reference to the drawings, wherein:
Embodiments of the present invention are illustrated in
In order to positively retain the cartridge in the receptacle 56, opposite side wall resilient latches 68 are formed in peripheral wall 58 at positions corresponding to opposite lateral sides 22, 24 of cartridge 10. Each of the resilient latches has a pawl 70 projecting from the upper edge of the resilient latch peripheral wall segment 72, in a plane generally corresponding to planar surface 54, a short distance into receptacle 56 in order to overlie the top surface of upper half 14 of cartridge 10 when cartridge 10 is supported within receptacle 56. Each of resilient latches 68 comprises a wall segment 72 of the peripheral wall 58, the wall segment 72 being defined by a U-shaped slit 74. The spaced apart legs 74a of U-shaped slit 74 extend through a portion of floor 60, upwardly and vertically through peripheral wall 58 and outwardly a short distance into planar surface 54. The base 74b of the U-shaped slit 74 extends through planar surface 54 parallel to the lateral sides of receptacle 56 to interconnect the free ends of the spaced apart legs 74a of the U-shape to define a resilient latch 68 which is cantilevered from floor 60 of receptacle 56 and free to resiliently flex toward and away from receptacle 56, independent of the remainder of the peripheral wall.
Cartridge 10 is inserted into receptacle 56 by first placing the continuously curved part 26 of the cartridge, held at an oblique angle to floor 60, into the receptacle 56 adjacent the corresponding shaped lower portion of the receptacle. Cartridge 10 is then pivoted about continuously curved part 26 to insert it into the cartridge. When the lateral sides 22, 24 of cartridge 10 come into contact with pawls 70 of the latches 68, which project from wall segments 72 and into receptacle 56, the downward pressure on pawls 70 causes the wall segments 72 to flex outwardly away from receptacle 56, allowing the cartridge 10 to seat in the appropriately shaped and dimensioned receptacle 56. As the cartridge 10 passes pawls 70, the resilient wall segments return to their rest positions with pawls 70 overlying the top surface of cartridge 10 to maintain it in place in receptacle 56.
To remove cartridge 10 from receptacle 56, a user simply places a thumb on the continuously curved part 26 of cartridge 10 and a second or third finger into finger well 59, applying pressure to the outside peripheral wall of the arc shaped part 20 of cartridge 10. A slight lifting action applied to the arc shaped part 20 while holding the thumb in place on the continuously curved part 26 causes the cartridge 10 to pivot about the continuously curved part 26. The upward pressure of the lateral walls 22, 24 on the pawls 70 during pivoting causes the wall segments 72 to flex outwardly away from receptacle 56 and out of contact with the top surface of cartridge 10, allowing the cartridge to be easily removed from receptacle 56. At least partly because of the angled removal facilitated by trays in accordance with the invention, the pawls 70 do not catch on the lower half 16 of cartridge 10 during removal, as with prior art devices. Furthermore, the optical disc 18 is rarely, if ever accidentally touched by the user during removal, since the head receiving aperture 38, which exposes the optical disc 18, is not near the user's hand during insertion or removal.
As can be seen from

The latching mechanism 98 of the tray 92 of
Alternatively, the latches 98, as well as the latches 68, can be configured so as to frictionally engage edges of UMD cartridges, in addition to or instead of being provided with a pawl 97. In such embodiments, the latches can be formed with an inwardly-directed bias. Therefore, when a UMD cartridge is inserted into a receptacle 96, the latches 98 are urged outwardly, with the inward bias thereof exerting a force upon edges of the UMD cartridge to frictionally engage the cartridge. If desired, a material having a high coefficient of friction, with respect to the surface of UMD cartridges can be provided on a surface of the latches 98.
As illustrated in, for example,
As best seen in
The peripheral wall 95, defines sidewalls of each receptacle 96, and bottom wall of a topmost receptacle 96c and top of bottommost receptacle 96a. However, a protrusions 97 are formed thereon to closely follow the contour of the UMD cartridges to be held therein. This enables secure transport and storage for the cartridges, while also allowing the benefits of compact storage, by holding multiple UMD cartridges in a single tray. As best seen in
Cartridge 10 is inserted into receptacle 96 by first placing the continuously curved part 26 of the cartridge, held at an oblique angle to floor 60, into the receptacle 96 adjacent the corresponding shaped lower portion of the receptacle. Cartridge 10 is then pivoted about continuously curved part 26 to insert it into the cartridge. When the lateral sides 22, 24 of cartridge 10 come into contact with pawls 90 of the latches 98, which project from wall segments 95a and into receptacle 96, the downward pressure on pawls 70 causes the wall segments 95a to flex outwardly away from receptacle 96, allowing the cartridge 10 to seat in the receptacle 96. As the cartridge 10 passes pawls 90, the resilient wall segments return to their rest positions with pawls 90 overlying the top surface of cartridge 10 to maintain it in place in receptacle 96.
To remove cartridge 10 from receptacle 96, a user simply places a thumb on the continuously curved part 26 of cartridge 10 and a second or third finger along the arc-shaped portion 20 of the cartridge 10, applying pressure to the outside peripheral wall of the arc shaped portion 20. A slight lifting action applied to the arc shaped part 20 while holding the thumb in place on the continuously curved part 26 causes the cartridge 10 to pivot about the continuously curved part 26. The upward pressure of the lateral walls 22, 24 of the cartridge 10 on the pawls 90, during pivoting, causes the wall segments 95a to flex outwardly away from receptacle 96 and out of contact with the top surface of cartridge 10, allowing the cartridge to be easily removed from the receptacle 96.
At least partly because of the angled removal facilitated by trays in accordance with the invention, the pawls 90 do not catch on the lower half 16 of cartridge 10 during removal. Furthermore, the optical disc 18 is rarely, if ever, accidentally touched by the user during removal since the head receiving aperture 38, which exposes the optical disc 18, is not near the user's hand during insertion or removal.
As can be seen in
