Under[0001]35 USC §119(e)(1), this application claims the benefit of prior U.S. provisional application no. 60/347,634, filed Jan. 11, 2002, which is hereby incorporated by reference in its entirety.
TECHNICAL FIELDThis invention relates to packaging for objects with a central opening, particularly flat discs used as recording media.[0002]
BACKGROUNDTypically flat recording media such as music or video discs have a central opening. Such media may be packaged in single use packages for mailing, point-of-sale display or other functions. Disc packaging should hold the disc securely in place, yet allow the user to remove it. The packaging should be easy to mass produce at relatively low cost.[0003]
U.S. Pat. No. 5,332,089 discloses a compact disc storage package that includes a holder formed of an easily but resiliently compressible material, configured and dimensioned to extend snugly through the disc's central aperture. In that way, the holder retains the recording medium until the recording medium is forcibly removed.[0004]
Other prior art CD packages include those disclosed in U.S. 5,205,405; 5,219,417, and 5,788,068.[0005]
SUMMARYI have discovered a storage package for recording media (especially CD's) that meets several needs. The package includes a fastener The fastener has an outer (generally flexible and planar) member positioned on the side of the recording medium opposite the packaging panel with a central member that is attached to a packaging panel and extends through the central aperture of the recording medium, connecting the panel to the outer member in order to keep the recording medium associated with the panel.[0006]
In one embodiment, the outer (flexible planar) member is not attached to the recording medium, but its dimension (e.g., diameter) is greater than the central aperture so that the fastener cannot easily (or accidentally) extend through the aperture to release the recording medium from the packaging panel.[0007]
In a second embodiment, the outer member is attached to the recording medium, so that the fastener forms a direct connection between the packaging panel and the recording medium.[0008]
One particular embodiment features a fastener that is an injection molded (e.g., as a single piece or part) fastening cap which comprises the central member and the outer member. The central member may include a top surface with an embossed or moleded design. The outer member may include a positioning key for orientation.[0009]
The panel may be a fold-out/pop-up panel contained within a folding package. When the package is unfolded, the panel pops up to display, and provide easy access to, the recording medium.[0010]
The details of one or more embodiments of the invention are set forth in the accompanying drawings and the description below. Other features, objects, and advantages of the invention will be apparent from the description and drawings, and from the claims.[0011]

Like reference symbols in the various drawings indicate like elements.[0018]
DETAILED DESCRIPTIONIn FIG. 1, the[0019]storage package10 includes a flat paperboard back panel12 and anover-panel14 with acircular opening16 to displayCD18 contained within the package. A fastener20fixes CD18 topackage10.
FIGS.[0020]2A-2D disclose one particular embodiment for fastener20. In those figures, a fastener20 (best shown in FIG. 2D) is an integral polymeric part having a central member orsegment42 and aplanar member44. FIG. 2A is a front view (from the same view as in FIG. 1). FIG. 2B is a back view (from the panel side of fastener20). FIG. 2C is a cross-section offastener20. Fastener20 is an integral part, in effect a disc with acentral portion44 that can be “debossed” (pressed inward) to maintain an operable configuration in which thecentral member42 is attached to thepackaging panel12. The back face ofplanar member44 is attached directly to the front face of therecording medium18 around the periphery of its central aperture. The material for this integral fastener is a laminate such as a polyethylene terephthalate (e.g., 0.0065 rigid PET film), laminated to a foil (e.g., 0.002 dead soft bright silver foil). This combination of materials is satisfactory to maintain theplanar member44 is directly attached to the face of CD38 opposite to panel32. Planarmember44 has a diamerter of about 1.125″. The debossedcentral member42 is about 0.5″ in diameter at the front, and is radiused to about 0.375Δ at the back. It has a depth of about 0.062″. This embodiment is better suited to automation.
FIGS.[0021]3A-3C disclose a second embodiment forfastener20, which includes acentral member22 attached at one end topanel12 and aflexible planar member24 positioned on the side ofCD18 opposite topanel12.Central member22 is a cylindrical piece of foam one face of which is attached topanel12 and the other face of which is attached toplanar member24.Planar member24 is substantially larger than the central aperture ofCD18, andmember24 is not attached toCD18.CD18 remains fixed topanel12 becausemember24 will not easily (or accidentally) fit through the aperture. In that way,CD18 will remain in place until the user removesfastener20 frompanel12 and discards the fastener; alternatively, the user could deformplanar member24 and force it through the aperture inCD18. Planarmember24 can be any suitable plastic, and preferably will accept printing, e.g. six color graphics. Alternatively,planar member24 is clear,central member22 can be heavy chipboard (about 0.050″ thick) rather than foam. In that case, printing oncentral member22 is visible from the top of the CD.
FIG. 4 is a highly diagrammatic view, not drawn to scale, showing an alternative to the embodiment of FIG.[0022]1 in which the panel to which the CD is attached pops out.Packaging50 includes aleft panel52 with acentral cutout55 hinged to aright panel54.Arcuate flap56 is attached toCD58 as described above using afastener60.Flap56 is attached at oneend57 to the inside ofleft panel52. The back offlap56 is attached to a hinged pop-out member62, illustrated in FIG. 5. Specifically,popout member62 includes amedial hinge64 dividing its left half66 (which is attached to the back of flap56) from itsright half68.Edge70 ofright half68 is fixed toright panel54. When packaged, hinge53 is closed so thatright panel52 overlies leftpanel54.Hinge64 is closed, so thatflap56 is positioned betweenpanels52 and54, withCD58 visible through thecentral cutout55. Whenhinge53 is opened, hinge64 is also pulled open. As that happens,flap56 pops out, supported by pop-out member62, to the open position shown in FIG. 4.
In another embodiment shown in FIGS.[0023]6A-6C, the fastener is an injection molded disc, with a central debossed region that passes through the center hole in the CD. The debossed region is attached to the panel using hot melt glue. FIG. 6B is a side view of a one-piece injection molded plug/cap unit120 that has a patternedbottom plug face122 to receive adhesive124 (e.g. hot melt adhesive). The pattern assists in receiving adhesive. In FIG. 6A, theplug region126 is thicker than the thickness of the disc being secured in the packaging. For example, for astandard disc134 in FIG. 6C of about 0.045″ thick, the plug is about 0.060″ thick. Theplug region126 is tapered, becoming wider as it reaches a flexible cap region. Thecap region128 is wider than the disc hole. Thetop surface130 of the cap region is suitable for molded lettering. Aregistration notch132 orients the cap so that the orientation of the lettering on the top of the cap is correct. Alternatively, the top surface of the cap can include foil that is stamped with a design and/or text.
The above described alternative embodiment is assembled by applying hot melt adhesive to face[0024]122 and adhering plug/cap120 to the board, withCD134 in place. Application of a design or lettering to face130 can be accomplished before, during or after assembly. Once the adhesive is in place,CD134 cannot be removed without deformingcap region128.
A number of embodiments of the invention have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the invention. Accordingly, other embodiments are within the scope of the following claims.[0025]
