Compact disc storage package

Abstract: A storage package (10) for a compact disc or the like has a plurality of non-plastic panels (12) including a pair of end panels (12a,12c) and, optionally, at least one panel (12b) intermediate to and connecting the pair of end panels. The plurality of panels (12) is movable between an open orientation (Fig. 2) enabling access to the contents of the package and a collapsed orientation for storage purposes, each of the panels having a pair of opposed lateral sidewalls (19), and the plurality of panels in the collapsed orientation defining at least one spine (32,34). A holder (14) formed of plastic is disposed on one (12b) of the panels for receiving and maintaining a compact disc thereon. An end cap (16) is disposed on one of the end panels or pivotally on the holder (14), the end cap being adapted to releasably engage the holder when the plurality of panels (12) is in the collapsed orientation, thereby to preclude accidental movement of the plurality of panels out of the collapsed orientation.

Description: The present invention relates to packaging and, more particularly, to packaging for a compact disc or the like. U.S. Patent No. 4,709,812 discloses packaging for a compact disc (CD) or the like which is formed of a plastic CD holder for releasably receiving and holding a CD and a plurality of interconnected non-plastic (typically paperboard) panels which are moveable between an open position where the CD holder and any compact disc thereon are accessible, and a collapsed orientation for storage wherein the various panels overlap and protect the CD. The packaging uses less plastic than the well known jewel box (which is formulated almost entirely in plastic), and the plastic which it does use, as well as the paperboard, may be both recycled and recyclable. Nonetheless, this packaging has not proven to be entirely satisfactory in use. As no provision is made for securing the packaging in its collapsed orientation for storage, the packaging can accidentally become opened (i.e., the plurality of panels moved to its open orientation), thus exposing the compact disc to dirt, fingerprints, and the like. Also, the holder has a face which is approximately the same size as, or even smaller than, the paperboard panels so that the edges of the latter are coextensive with or even project outwardly from the holder with the result that they are susceptible to dog-earing, fraying crushing and like disfigurement due to handling. Further, although the spine of the packaging in its collapsed orientation typically contains important identifying information (such as the nature of the matter recorded on the CD) intended to be viewable when the packaging is stored appropriately against like CD packages with only the package edges visible, no protection is provided for the spine so that, with continued handling of the packaging, the spine is subject to deterioration, and with it the identifying information thereon. (This is a special problem since in certain storage devices only the spine is exposed to the viewer and, therefore, the viewer has to forcibly grasp the spine and utilize it in order to separate the desired packaging from the remainder of the packaging in the same storage device.) Where the packaging contains a secondary spine opposite the primary spine, the secondary spine is also subject to dog-earing and the like even though this is of lesser importance than in the case of the primary spine since the secondary spine rarely contains identifying information of importance to the user. There is also known, see US-A-4867302, a case for keeping a recording medium which comprises first and second case members that are relatively pivoted and that support a pivoted recording medium holder. One of the case members incorporates a pivoted end cap that engages the other case member to retain the case in a closed position with the recording medium holding member enclosed therein. However, such a case is intended for relatively large and heavy recording media rather than a CD, and, moreover, is of the kind that would be formed entirely in plastic. Thus there is no teaching relating to the'improvement of a CD holder of the kind incorporating interconnected non-plastic panels of paperboard or like material. It is accordingly an object of the invention to provide an improved means that is applicable to compact disc packaging of the kind incorporating non-plastic panels of paperboard or the like, that provides improved protection for the packaging when in its closed orientation. This object is achieved by the features of Claim 1. BRIEF DESCRIPTION OF THE DRAWINGS The above and related objects, features and advantages of the present invention will be more fully understood by reference to the following detailed description of the presently preferred, albeit illustrative, embodiments of the present invention when taken in conjunction with the accompanying drawings wherein: Figure 1 is a top plan view of the packaging for a compact disc or the like according to one embodiment of the present invention, the packaging being illustrated in the open orientation and the folded portions of the blank prior to folding being illustrated in phantom line; Figure 2 is a bottom plan view thereof; Figure 3 is a side elevational view thereof, but with an end panel also being illustrated in phantom line in an intermediate position partially, but not fully, folded over; FIG. 4 is a top plan view thereof to a slightly enlarged scale, in the closed orientation; FIG. 5 is a side elevational view similar to FIG. 4, but with two panels being illustrated in phantom line in an intermediate position partially, but not fully, folded over; FIG. 6 is a top plan view of the packaging according to a further embodiment of the present invention, the packaging being illustrated in the open orientation and the folded portion of the blank prior to folding being illustrated in phantom line; FIG. 7 is a bottom plan view thereof; FIG. 8 is a side elevational view thereof; FIG. 9 is a top plan view thereof, to a slightly enlarged scale, in the closed orientation, with portions thereof broken away to reveal details of the internal construction; and FIG. 10 is a side elevational view similar to FIG. 9. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is a storage package for compact discs and the like. Encompassed by the term "compact discs and the like" are CD-ROM's, diskettes, and the like, which may be blank or prerecorded and may contain or be adapted to contain music, words, images, binary data, and the like as well as combinations thereof. Referring now to the drawings,and in particular to FIGS. 1-5 thereof, therein illustrated is a storage pack according to the present invention, generally designated by the reference numeral 100. The storage pack 100 is composed of a plurality of non-plastic panels generally designated 112, a holder formed of plastic generally designated 114, and an end cap formed of plastic generally designated 116. Unlike the all-plastic jewel box conventionally used for the storage of CD's, the packaging of the present invention is to a large degree formed of the non-plastic panels 112, the latter preferably being formed of paperboard which readily decomposes under landfill conditions and is thus more ecologically acceptable than plastic. Moreover, both the paperboard and plastic components of the present invention may be made from recycled materials and are themselves recyclable, thereby rendering the package not only ecologically but also economically sound. While FIGS. 1-5 illustrate a three-panel embodiment of a package according to the present invention, similar packages utilizing the principle of the present invention may be formed from fewer panels or more panels. The plurality of non-plastic panels 112 may be formed from a prescored, preprinted unitary blank or sheet generally designated 120. The blank 120 is preferably divided into rows. The first row 122 has a number of rectangular sections equal to the number of panels in the plurality (here, three): namely, the sections 122a, 122b and 122c. The three sections 122a, 122b, 122c in the first row 122 are separated from each other by strips 124 having a width which is small relative to the width of the sections, the strips being bounded by foldlines 126. As will become apparent hereinafter, the width of the strips 124 will be determined by the need of the strip to accommodate the gap between adjacent rectangular sections 122 when the plurality of panels 112 is disposed in a collapsed orientation for storage purposes, with each of the panels 112 being in overlapping relationship. For reasons of economy, the blank 120 is typically multi-color printed on only one surface thereof, although it is desirable for aesthetic reasons that both major surfaces of the panels 112 which will be exposed to view be multi-color printed. The opposed surface of the blank 120 is typically either left in its original color or printed with only a single color. Accordingly, the blank 120 preferably also has a second row 28 composed of one or more unconnected rectangular sections such as section 128c. Accordingly, when rectangular sections 122c and 128c are both multi-color printed on only one surface, one is then folded over a foldline therebetween so as to be in overlapping relationship and define a panel 112c with the multi-color printed surfaces of the sections exposed and the non-multi-color printed surfaces glued together and thus hidden from view. Preferably, for a variety of reasons, there is no section in the second row 28 adjacent the section 22a which is adapted to receive the holder 14. First, since panel section 22a will have one surface totally covered by the holder 14, there is no aesthetic reason for having an adjacent section in the row 28. Second, the non-multi-color-printed or non-coated surface of section 22a enables the holder 14 to be better secured thereto than it would be to a multi-color-printed surface. Third, the missing section is not necessary to impart additional strength and rigidity to the section 22a (as it would if the missing section and section 22a were folded over and glued together) since section 22a is subsequently strengthened and rigidified by the presence thereon of the holder 14. Fourth, the missing section would unnecessarily increase the thickness of the entire package in its collapsed orientation, this being a particular problem where the package is intended to occupy the same volume as a conventional jewel box (for example, to enable the use of existing storage facilities for conventional jewel-box CD packaging). A section 128b, similar to section 128c of the second row 28, may be placed in the second row adjacent the section 122b of the first row, with a foldline being disposed therebetween. In this case the section 128b may be folded over the foldline and glued to its adjacent section 122b in the same manner as section 128c is folded over and glued to adjacent section 122c to form a panel. However, as it is frequently desirable to place removable literature within the CD packaging (such as a booklet describing the prerecorded matter, the creation of the matter, the artist, instructions for use, or the like), the section 128b may be glued to the section 122b only at the two lateral ends thereof (the end of section 122b adjacent section 122a and the end thereof adjacent section 122c) so as to define with section 28c a panel 112b having an open-top pocket into which such literature or booklet may be stored. To facilitate access to the pocket, this section 128b is preferably somewhat in the configuration of a right-angle trapezoid rather than a rectangle, with the free long end of section 128b being glued to the end of section 122b adjacent section 122c and preferably the free short end of section 128b being glued to the end of section 122b adjacent section 122a. The plurality of non-plastic panels 112 formed from the blank 120 (after folding and gluing of the sections of the second row 128 to adjacent sections of the first row 122) include a pair of end panels 112a and 112c and, optionally at least one panel 112b intermediate to and connecting the pair of end panels 112a, 112c. The plurality of non-plastic panels 112 further defines a pair of opposed free ends 118 and a pair of opposed lateral sidewalls 119. Panel 112a is, of course, composed only of section 122a. The plurality of panels 112 is movable between an open orientation enabling access to the contents of the package (see Figs. 1-3), through an intermediate orientation wherein some of the panels are overlapping, and a collapsed orientation for storage purposes (see Figs. 4 and 5) wherein all of the panels 112a, 112b, 112c are overlapping. In other words, in the open orientation there is no panel overlying the panel 112a on which the holder 114 is disposed, thereby enabling access to the holder 114 and any compact disc thereon, and in the collapsed orientation each of the panels 112a, 112b, 112c overlaps one another, thereby to provide a compact package for storage. The holder 114 preferably comprises an injection molded plastic element which differs in particular respects from the holder found in the conventional prior art jewel box. The holder 114 together with an end cap 116 forms one embodiment of an intermediate in accordance with the invention and is disposed on the panel 112a to form the complete package. It will be appreciated that while a three panel embodiment is illustrated, fewer panels or more panels may be used. Preferably, the panel 112 on which the holder 114 is disposed defines an extension 208 beyond the end of the holder 114 so as to enable the extension 208 to wrap around and cover the back surface of the end cap 116, as will be explained in greater detail hereinafter. While the open-top pocket for holding literature or a brochure is illustrated as being defined by panel 112b, clearly the same could be defined instead by panel 112c or dispensed with entirely (in which case the partial section 128b would typically be full sized and completely cover the opposing face of section 122b). Panel 112a is, of course, composed of only the single section 122a as that is the panel on which the holder 114 will be disposed. In its conventional aspects, the holder 114 has a generally planar rectangular body 140 defining a recess 142 on the exposed surface thereof configured and dimensioned to receive the centrally apertured CD (which is typically approximately 12cm (4.7") in outer diameter). The depth of the recess 142 is sufficient to ensure that the upper surface of the CD does not extend above the surface of the holder body 140 about the recess 142. A retaining element 144 is centrally disposed in recess 142, projecting upwardly therefrom, for retaining the CD in holder 114. Any of the conventional means for providing frictional engagement between the retaining element 144 and the inner circumference of the CD may be used--for example, upstanding pliable plastic tabs such as those used in the holder of the conventional jewel box to frictionally engage the inner circumference of the central hole of the CD and thus hold the CD in place. Additionally, a plurality of finger slots or recesses 146 (two being illustrated) are preferably provided so that the user can slide a finger below the edge of the CD while simultaneously exerting a slight downward force on the retaining means 144 to facilitate disengagement of the CD from retaining element 144 for removal of the CD from the recess 142. The finger recesses 146 are preferably disposed at opposite ends of a diameter of the holder recess 142 extending from end to end of holder 114, for example, parallel to the sidewalls 150 thereof. The holder 14 is disposed on an end panel (here, end panel 112a, but optionally end panel 112c). When the plurality of panels is in a collapsed orientation as illustrated in Figs. 4-5, the other end panel 112c and any intermediate panels (here, panel 112b) are disposed intermediate the end panel 112a bearing the end cap 116 and a portion 164 of the end cap 116. The holder 14 further includes a pair of opposed lateral sidewalls generally designated 150, disposed slightly outwardly from the sidewalls 19 on panel 122a on which it is disposed. Each holder sidewall 50 includes a first portion 52 which extends substantially upwardly above the plane of the holder body 42 for essentially the entire length of the holder 114 and the first portion 152 defines engagement means, illustrated as an aperture 172 disposed above the plane of the end panel 112a, which functions to releasably engage cooperating engagement means disposed on the end cap 116. Additionally, holder sidewalls 150 extend appreciably downwardly below the plane of the holder body 142 for substantially the entire length thereof. More particularly, as best illustrated in Fig. 5, the holder sidewalls 150 extend downwardly below the plane of the holder body 140 at least the thickness of the panel 112a on which the holder 14 is disposed and upwardly from the plane of the holder body 40 at least the thickness of the remainder 112b, 112c of the panels when the plurality of panels 12 is in the collapsed orientation. Thus, the holder sidewalls 50 essentially overlap and protect the sidewalls 19 of the plurality of panels 12a, 12b 12c in the collapsed orientation. All portions of the end panel sidewalls 118 are protected by the holder sidewalls 150. The plastic end cap 116 is directly pivotally secured to the holder 114, and more particularly to the adjacent end 114a of the holder 114. The end cap 116 is secured to the holder end 114a by a living hinge 200 and is of unitary, one-piece, integral construction with the holder 114, both being formed together in a single molding operation. The plastic utilised for the holder 114 and end cap 116 (and, of course, living hinge 200) must be strong, yet substantially flexible when thin so as to be capable of forming a living hinge, and polypropylene is preferred. The living hinge 200 extends substantially the entire width of the holder 114 between the sidewalls 150 thereof. The living hinge 200 is preferably formed as a line of reduced thickness in the plastic intermediate holder 114 and end cap 116, with the facing portions of those elements adjacent the living hinge 200 preferably being beveled so as to enable a pivotal movement of the end cap 116 through at least 90°. The end cap 116 is thus typically the same color as the holder 114 and devoid of any transparent portion. End cap 116 is generally U-shaped and has a pair of upstanding opposed lateral sidewalls 160 and a connecting portion generally designated 201, connecting the same. The connecting portion 201 is L-shaped in cross-section and includes a bight portion 162 and an upstanding end wall 164 which is perpendicular to bight portion 162. The end wall 164 is configured and dimensioned to serve as a latch and preferably includes a lip 202 on its free end to facilitate grasping of end cap 116 and improve the leverage exertable thereon by a user. End cap 116 is pivotable about the living hinge 200 from a non-latching orientation wherein the bight portion 162 is in generally the same plane as the holder 114 and the end wall 164 is transverse thereto (as illustrated in FIGS. 1-3), and a latching orientation wherein the bight portion 162 is substantially transverse to the plane of the holder 114 and the end wall 164 is generally parallel thereto (as illustrated in FIGS. 4-5). The end cap sidewalls 116 are connected directly to both bight portion 162 and end wall 164, and each defines an engagement means 170, illustrated as an outwardly projecting lug, adapted to releasably engage the cooperating engagement means 172, illustrated as an aperture or recess on the holder sidewall 152. As illustrated, end cap engaging means 170 are outwardly projecting lugs on the outer surface of each end cap sidewall 160, and the holder engaging means 172 are apertures or recesses on each holder sidewall 150, configured and dimensioned to receive and releasably retain projecting lugs 170 therein, thereby to preclude accidental movement of the plurality of panels 112 out of the collapsed orientation. Clearly, however, the apertures 172 could be on the end cap sidewalls 160 and the projecting lugs 170 could be on the holder sidewalls 150. Indeed, easily releasable engagement means other than an aperture-and-lug system may be substituted. In order to limit the pressure exerted by the end cap latch 164 on the holder 114, and thus on any compact discs disposed within the holder recess 142, end cap 116 defines abutment means 180 in the form of a lug extending outwardly from each sidewall portion means 160 thereof, and each holder sidewall 150 defines a fixed upper abutment surface which is adapted to engage a lug 180 and function as a stop to limit movement of the end cap 116 from its non-latching orientation beyond its latching orientation. Alternatively, or in addition thereto, the appropriately bevelled surfaces of the holder 114 and end cap 116 about the living hinge 200 may also limit the pressure exerted downwardly by the end cap latch 203 on holder 114. The sidewalls 160 of the end cap 116 are spaced apart such that they are readily received between the sidewalls 150 of the holder 114 as the end cap 116 is moved into the latching orientation, with the engagement means 170, 172 of the end cap 116 and the holder 114, respectively, releasably engaging. To enable easy pivotal movement of the end cap 116 to the latching orientation, the holder sidewalls 150 about the engagement means 172 and adjacent the living hinge 200 are preferably resiliently outwardly flexible so as to flexingly accommodate passage of the lugs 170 between holder sidewalls 150 until the lugs 170 seat in the apertures 172. Alternatively, or in addition thereto, the end cap sidewalls 160 may be resiliently inwardly flexible. As earlier mentioned, the panel 112a (formed of section 122a) preferably defines an extension 208 at its free end, the extension 208 being glued to the outer surface of bight portion 162 of the end cap 116. The extension 208 serves as a spine and is printed with identifying information for the CD in the package 100. Preferably, the outer surface of end cap bight portion 162 defines a recess adapted to receive the extension 208 therein so that the edges of extension 208 are protected against dog-earing, fraying or the like. Referring now to FIGS. 6-10, therein illustrated is a second embodiment 100' which is similar to the first embodiment 100 except that the end cap and the holder are connected by a pair of pin-and-hole hinges rather than a living hinge. Elements of the second embodiment corresponding in structure or function to elements of the first embodiment are identified by corresponding numerals primed. Referring now to FIG. 6 in particular, the blank used in the second embodiment 100' is substantially similar to the blank used in the first embodiment 100 except that, since the second embodiment 100' is illustrated as a two-panel embodiment, there is no panel corresponding to panel 112c (or the sections 122c and 128c from which panel 112c would be formed). Clearly, however, the second embodiment 100' could alternatively have a greater number of panels 112. Further, the extension 208 of panel 112a is glued not to the end cap (as in the second embodiment 100), but rather to the end 114a' of the holder 114' adjacent the end cap 116'. While the extension 208 may be partially or wholly concealed by the end cap 116' when the plurality of panels is in the open orientation, when the plurality of panels is in the closed orientation (as illustrated in FIGS. 9-10) the extension 208 is easily visible. The holder 114' of the second embodiment 110' is in most respects similar to the holder 114 of the fourth embodiment 100, but the raised sidewall portions 152' thereof do not extend to the holder edge 114a' and thereby leave a sidewall portion 220 of the main holder body exposed. Disposed on each exposed holder sidewall portion 220 are engaging means 172', illustrated in the form of a recess or aperture adjacent the end of the first portion 152' of the holder sidewall 150', and a pin-receiving aperture or recess 302 adjacent the holder end wall 114a' and thus the end cap 116'. The end cap 116' of the second embodiment 100' is generally similar to the end cap 116 of the first embodiment 100, but differs in certain critical respects. The end cap 116' is generally U-shaped and defines a pair of upstanding sidewalls 160' and a connecting portion 201' which connects the same and serves as the end wall 164' (there being no portion corresponding to bight portion 162 of the first embodiment 100). The end cap sidewalls 160' are further spaced apart so that they are in the same planes as the holder sidewalls 150'. Each of the end cap sidewalls 160' defines an inwardly projecting pin 304 (best seen in FIG. 9) which is pivotably received within the holder aperture or recess 302 to define a pin-and-aperture hinge. The two pin-and-aperture assemblies 304, 302, one at each side of the holder 114', defines a pair of hinges enabling pivoting of the end cap 116' relative to the holder 114' between the unlatching orientation and the latching orientation. When the package is in the closed orientation, the end cap sidewalls 160' extend to or almost to, the ends of the holder sidewall portions 152' (so as to cover the exposed holder sidewall portions 220) and cooperate therewith in protecting sidewalls 118 of the panel 112b from dog-earing, fraying or the like. While the living hinge 200 of the first embodiment 100 is illustrated as connecting the end cap 116 to the bottom of the holder 114 (that is, the portion of holder 120 closely adjacent to the panel 112a on which it is secured), alternatively the living hinge 200 may connect the end cap 116 to the top of the holder 114. In substance, the living hinge 200 would then directly connect the holder 114 and the upstanding end wall 164 of end cap 116, with the end cap sidewalls 160 extending transversely to the upstanding end wall 164. In such a variant of the first embodiment 100, the holder 114 and end cap 116 would typically be similar in structure to the corresponding elements 114', 116' of the second embodiment 100' except that living hinge 200 would be employed instead of the pins 304 and apertures 302. Indeed, in another variant of the first embodiment wherein the living hinge connects the end cap 116 to the top of the holder 114 (rather than the bottom thereof), the sidewalls 160 of the end cap 116 may be closer together than the sidewalls 150 of holder 114, and downwardly extending slots may be provided in the upper surface of the holder 114 for receipt therein of the end cap sidewalls 160 when the end cap 116 is in the latching orientation. An aperture on one side of each slot would receive the projecting lugs of the end cap sidewalls in order to releasably maintain the end cap 116 in the latched orientation. Thus it will be appreciated that, depending upon the preferred variant, the sidewalls of the end cap may be disposed either within the same plane as the sidewalls of the holder or closer to one another. Typically, the sidewalls of the end cap should not be disposed outwardly of the planes of the sidewalls of the holder as this increases the overall size of the packaging without a corresponding benefit. To summarize, the present invention provides packaging for a compact disc or the like which includes means for maintaining the packaging in the collapsed orientation, and means to prevent dog-earing, fraying or like destruction of the spines and the exposed sidewall edges of the paperboard panels. The package is ecologically sound, since it may be composed substantially of recycled and/or recyclable plastic and paperboard, as well as being simple and economical to manufacture. Now that the preferred embodiments of the present invention have been shown and described in detail, various modifications and improvements thereon will become readily apparent to those skilled in the art. Accordingly, the scope of the present invention is to be construed broadly and limited only by the appended claims, and not by the foregoing specification.
