This invention relates to sleeves for holding recording discs, and more specifically digital video discs and their accompanying graphics.
Compact discs, or “CD”'s as they are commonly called, carry digital information such as sound and music recordings and more recently movies and video games with accompanying sound known as Digital Video Discs (hereinafter collectively “DVDs”). The DVDs replace popular video cassettes which are typically played on video cassette recorders (VCRs), and more commonly may be played on personal computers.
DVDs are generally sold to consumers in “jewel boxes” which are rigid plastic containers which carry both the DVD and accompanying graphics which identify the particular movie, video game or program contained on the DVD. The jewel boxes are bulky, difficult to store and are not conveniently opened or closed to remove the DVD. Furthermore, the graphics sold in association with the DVDs are oversized and generally resemble the size and shape of video cassettes as opposed to the width and length of the DVD. That is, the graphics are generally much longer than the DVD and additionally slightly wider. Thus, storing the DVD in a form of flexible, lightweight storage sleeve and the corresponding graphics in a sleeve with equal sized pockets is problematic.
Although lightweight, flexible storage sleeves which are designed specifically for CD's are known in the art, these devices are not designed to hold the larger graphics sold in association with DVDS. Further, if a sleeve is manufactured which is compatible in length and width for the DVD graphics, the DVD pocket which is designed for holding the DVD will generally be oversized and not overly useful.
Thus, a lightweight, flexible storage sleeve for storing DVDs is needed which can additionally store the oversized graphics associated with the DVD in a similarly sized pocket. Further, the manufacturing of the DVD sleeve must be consistent with generally recognized sleeve manufacturing processes to maintain the low cost benefits associated with flexible storage sleeves as opposed to rigid plastic jewel boxes.
It is thus an object of the present invention to provide a lightweight, flexible sleeve to store DVDs and the accompanying oversized graphics in pockets with substantially similar widths. Thus, in one embodiment of the present invention a sleeve is provided which is comprised of a front layer, an intermediate middle layer and a back layer. A pocket is provided between the front layer and middle layer for receiving a DVD while a second pocket is provided between the middle layer and back layer to receive the graphics.
It is a further aspect of the present invention to provide a cost effective, non-woven material which is in contact with the DVD which prevents scratching, does not accumulate grit or other particles and which is firm enough not to require a backing sheet for support. In one aspect of the present invention a non-woven material known as “Veratec®” is provided to serve this purpose.
It is another aspect of the present invention to provide a DVD and accompanying graphics storage sleeve which has a storage pocket for the DVD and which has a “DVD stop seal” which allows the DVD to be stored at an elevated height, thus permitting the top edge of the DVD to be near the access opening of the DVD storage pocket for easy access. The stop seal prevents the DVD from falling into the DVD storage pocket and inhibiting removal.
In one embodiment of the present invention, the stop seal is provided by utilizing a back sheet with a back sheet aperture in conjunction with a conventional manufacturing process to minimize expenses during manufacturing. Alternatively, the sleeve with a stop seal may be manufactured without utilizing a back sheet aperture.
In another aspect of the present invention, the same technology which provides the DVD stop seal in the DVD storage pocket is utilized to provide one or more “frictional nubs” to be provided in the DVD storage pocket. The “frictional nubs” prevent the DVD from falling out of the DVD storage pocket when the sleeve is turned upside down. For example, in one embodiment of the present invention the DVD storage pocket may utilize a top layer which is approximately the length of the DVD and which has a “thumb cut” or notch to allow access to the aperture of the DVD with a user's fingers or thumb. in this embodiment, there is no flap which overlays the DVD. Since the storage pocket has a diameter which is slightly larger than the DVD (as a result of the oversized graphics pocket), the DVD falls from the pocket when the sleeve is turned upside down.
To alleviate this problem, the frictional nubs engage the side edges of the DVD and prevent the DVD from inadvertently falling out of the DVD pocket. In one embodiment of the present invention the frictional nubs are provided by the sealing of the front sheet and middle sheet at one or more predetermined locations to create a DVD pocket diameter which is slightly larger than the diameter of the DVD yet provides sufficient frictional resistance to prevent the DVD from inadvertently falling out. The frictional nubs may be provided during an ultrasonic or RF welding process by providing one or more apertures in the back sheet which allow the ultrasonic welding to occur at a predetermined location without welding any other portion of the front, middle or back sheet. Alternatively, the frictional nubs may be provided without utilizing back sheet apertures by utilizing a two stage manufacturing technique which first welds the front sheet and middle sheet together while creating the frictional nubs. The back sheet is then welded in a second stage to the front and middle sheets to complete the DVD sleeve.
It is another aspect of the present invention to provide a manufacturing process for producing a sleeve design for DVDs and accompanying graphics which utilizes a “cutout” portion in the back sheet to provide either the DVD stop seal or frictional nubs on the front sheet as discussed above. Thus, in one aspect of the present invention a “cutout” or aperture in the back sheet is utilized in combination with a sheet bonding process to interconnect the front sheet and middle sheet at preselected positions to either provide a DVD stop seal in one sleeve design or one or more frictional nubs in another embodiment of the invention. Alternatively, a manufacturing process is provided which does not utilize or require a back sheet aperture to create either the DVD stop seal on the functional nubs.
In another aspect of the present invention, a “write-on” title strip is provided either along the upper edge or lateral edge of the DVD sleeve which is made of a material which permits the recordation of information related to the stored DVD either in pen, ink, or pencil.
Referring now to the drawings,
The DVD sleeve 2 is generally comprised of a front or top sheet 6, a middle sheet 18 and a back sheet 20. A DVD pocket 22 or sleeve capable of holding a DVD is formed between the front sheet 6 and middle sheet 18 while a second graphics pocket 24 or sleeve is formed between the middle sheet 18 and back sheet 20 for holding the graphics 22 associated with the DVD
In one aspect of the present invention, both the front sheet 6 and middle sheet 18 are comprised of a spun-bonded, non-woven material to prevent scratching of the DVD. In an alternative embodiment, a non-woven material such as Veratece is provided. Alternatively, woven materials or other non-woven materials such as Sontara® can be used with or without any type of reinforced backing sheet made of polypropylene or other similar materials. The back sheet 20 is preferably a transparent polypropylene material which enables the user to clearly see the graphics positioned in the graphics storage pocket. Alternatively, any other type of transparent material may be used as appreciated by one skilled in the art. Various embodiments of the present invention sleeve design which have a configuration for storing two DVD's and not the accompanying graphics would preferably use non-woven materials for the front sheet 6, middle sheet 18 and back sheet 20.
Since the DVD graphics 26 are both slightly wider and substantially longer than the diameter of the DVD 4 which is stored in the opposing DVD storage pocket, modifications must be made to the DVD storage pocket to facilitate access to the DVD 4 and/or prevent the DVD from falling out of the storage sleeve if the sleeve is inverted. In the embodiments shown in
Since the DVD 4 has a diameter (and hence length) which is significantly less than the DVD graphics sheet 26, the overall DVD pocket 22 length must be substantially reduced to prevent the DVD 4 from falling into the pocket an excessive distance. Thus, a DVD “stop seal” 28 is provided and positioned approximately the diameter of a DVD down the length of the DVD pocket 22 from the sleeve upper edge 8 to hold the DVD 4 at an elevation which allows removal of the DVD 4 when the flap 14 is lifted upward. Preferably the DVD stop seal 28 is positioned at a location which places a top edge of the DVD near the hinge position of the flap 14.
The DVD stop seal 28 is created by interconnecting the flexible front sheet 6 to the middle sheet 18 at a predetermined location, yet not interconnecting the middle sheet 18 to the flexible back sheet 20 and hence reducing the size of the graphics pocket 24. The interconnection may be accomplished by individually sewing, heat bonding or otherwise interconnecting the front sheet 6 and middle sheet 18 prior to interconnecting the back layer. Preferably, the front sheet 6 is first interconnected to the middle sheet 18 by welding or other similar technique while the DVD stop seal 28 or frictional nubs 36 are additionally created by interconnecting the front sheet 6 and middle sheet 18 at predetermined locations. The back sheet is then interconnected to the middle sheet 18 by welding or other similar means to complete the DVD sleeve in the two stage manufacturing process.
Alternatively, to enable the DVD stop seal 28 to be created during conventional manufacturing processes where the front sheet 6, middle sheet 18 and back sheet 20 are simultaneously welded together, a back sheet “cutout” aperture 32 may be provided in the transparent polypropylene back sheet 20 prior to welding. Thus, as seen in

To alleviate the problem of the DVD inadvertently falling from the DVD pocket 22, frictional “nubs” 36 are provided as shown in
To provide the frictional nubs 36, in one embodiment back sheet “cutouts” or apertures 32 are provided in the back sheet 20 at the location immediately opposite the position on the flexible front sheet 6 and middle sheet 18 where the frictional nubs 36 are desired. The front, middle, and back sheets may then be ultrasonically welded along the top edge, bottom edge and lateral edges simultaneously during a bonding process while the middle sheet 18 and front sheet 6 are additionally bonded at the location of the frictional nubs 36. Similar to the DVD stop seals 28 previously discussed, any number of geometric configurations and/or number of frictional nubs 36 may be utilized to achieve the function of effectively reducing the internal diameter of the DVD pocket 22 to such a degree that the DVD 2 will not fall from the DVD pocket 22 when the DVD sleeve 2 is turned upside down.
Alternatively, and as previously discussed, it is possible to create the frictional nubs 36 without utilizing a back sheet aperture 32 by utilizing a different two stage manufacturing process which first welds the front sheet 6 and middle sheet 18 while making the necessary welds for the frictional nubs 36. The back sheet 20 is then interconnected to the first sheet 6 and middle sheet 18 by welding or interconnection method which is commonly known in the art.
As shown in

As seen in both the front and rear elevation views of
In the embodiment shown in
Referring now to the front elevation view shown in
In another aspect of the present invention a process is provided for manufacturing the DVD sleeves shown in
After the cutouts are made to the respective front and back sheets, the individual layers of material are all fed back together and aligned, at which time all of the weld seals of the three layers are made simultaneously. These welds include the seals required on the peripheral edges to form the pockets as well as the DVD stop seals 28 or frictional nubs 36 as the case may be. Once all of the welds have been made the continuous roll of sealed material is cut as appropriate to create the individual DVD sleeve 2. Although the process generally described utilizes ultrasonic welding to form the necessary seals, as appreciated by one skilled in the art RF (radio frequency) welding or other forms of interconnection can be implemented to create seals between various layers of now-woven or transparent type materials such as polypropylene.
Alternatively, in a method to provide the DVD stop seals 28 on frictional nubs 36 without utilizing a back sheet aperture 32, a two stage manufacturing process is utilized which first interconnects the front sheet 6 to the middle sheet 18 while additionally creating the DVD stop seal 28 or frictional nubs 36. The back sheet 20 is then interconnected to the middle sheet 18 and front sheet 6 to complete the DVD sleeve 2.
