Benefits of technology
[0007] 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.
[0008] 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.
[0009] 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.
[0010] 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.
[0011] 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.
[0012] 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.
Problems solved by technology
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.
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.

Embodiment Construction
[0037] Referring now to the drawings, FIG. 1 is a front elevation view of a first embodiment of the present invention. More specifically, the drawing shows a front elevation view of a DVD storage sleeve 2 capable of holding one DVD disc 4 and the associated graphics 26.
[0038] 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 FIG. 2 depicts a rear elevation view of the embodiment shown in FIG. 1.
[0039] 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 mater...

This invention relates to a sleeve for holding one or more digital video discs with a first dimension in a first pocket and the accompanying graphics having a second dimension in a second opposing pocket. The digital video disc is supported in the first pocket by one or more stop seals which elevate the digital video disc to a more accessible position for removal.
