Patent Application
20130186789
The present teachings relate to cases, sleeves, envelopes, and the like, for CD, DVD, other disc media, and/or other discs.
Many cases, sleeves, holders, envelopes, or the like, (herein, collectively, “cases” or “holders”) for CD, DVD, other disc media, other discs, or the like Ce.g., Blu-ray discs), (herein, collectively, “discs,” “disc media,” or “media”) are made of plastic and/or cardboard materials. Typical configurations use more material than is necessary. Also, they typically require the use of special manufacturing facilities, equipment, and machinery. Unfortunately, many such cases eventually break after heavy usage or mishandling, and often end up in landfills.
Some folded-paper cases have been proposed, however they generally require cuts and/or adhesives. Most are designed to hold no more than one CD or DVD at a time.
There is a need for a folded-paper case that is biodegradable and uses minimal material. As well, there is a need for such a case that can be made requiring neither cuts or glue, nor special equipment or machinery to manufacture. Further, there is a need for such a case that can hold plural disc media or other discs, such as two CDs or DVDs. Ideally, the footprint of the case would be minimal; e.g., only minimally larger than a CD or DVD it will hold.
Various aspects of the present teachings relate to a process for making a protective holder for one or more CD and/or DVD media, including any other similar media such as Blu-ray discs.
In various embodiments, the process can comprise, for example:
1. A standard rectangular sheet of paper or card stock is folded along the diagonal from corner to corner and creased.
2. The protruding flaps are folded over the opposing edge and creased.
3. A CD or similar-sized disk is centered on the resulting triangular shape to facilitate estimation of the location of the next fold. Alternately, the paper may be pre-marked to show the location of the next fold, or it may be “eyeballed”.
4. The narrow ends of the triangular shape are folded across the disk, or follow a marking, or by careful estimation, to create a shape that is very nearly a regular pentagon and the folds are creased. The top edges of these narrow ends are nearly flush where they overlap across the center of the pentagon.
5. The shape is unfolded as far as the first crease, which remains.
6. The narrow ends of the triangular shape are inverted by means of what may be referred to in the practice of origami as a_valley fold” so that they become located inside the main shape, with the bottom creases of the narrow ends becoming folded and creased in the opposite direction. This recreates the pentagon shape with the addition of two partial flaps extending to the top of the shape, plus two chambers or pockets almost entirely separated by a layer of paper inside the main shape.
7. One disk may be inserted into each pocket.
8. The top flaps are folded over and tucked into the main shape, trapping the disk/s inside.
Various embodiments relate to a product produced by the method as set forth above. In a variety of embodiments, the product is monolithic. In various embodiments, the product is made from no more than a single sheet of paper. According to a variety of embodiments, the single sheet of paper has a width of 8 ½ inches and a length of 11 inches. In various embodiments, the product is devoid of any cut, slit, glue, adhesive, perforation, hole, tear, or any combination thereof. In accordance with various embodiments, the product can comprise a single, folded sheet of paper; wherein the folded sheet of paper defines two generally planar pockets disposed in side-by-side relation; and further wherein the folded sheet of paper has a generally pentagon shape.
Further aspects of the present teachings relate to a case or sleeve for disk-shaped objects such as a CDs or DVDs, comprising a single, folded sheet of paper; wherein the folded sheet of paper defines two generally planar pockets disposed in side-by-side relation; and further wherein the folded sheet of paper has a generally pentagon shape.
According to various embodiments, the pockets are substantially parallel to one another. In various embodiments, each of the pockets is configured to receive a CD or DVD. In a variety of embodiments, a CD or DVD is held within each of the two pockets; with the case or sleeve further comprising a divider separating, at least in part, each CD or DVD from the other. According to a variety of embodiments, a ratio of the surface area of a CD or DVD held within the case or sleeve to the surface area of the pentagon shape of the case or sleeve is about I:1.2. In various embodiments, the paper comprising the case or sleeve is comprised of one or more biodegradable materials.
Further aspects of the present teachings relate to a case or sleeve for disk-shaped objects such as CDs or DVDs, comprising: a single, folded sheet of paper; wherein said folded sheet of paper has a generally pentagon shape comprising a plurality of edges, wherein all the edges are folds or securely tucked flaps.
Various non-limiting, exemplary embodiments will now be described.
According to various embodiments, and with reference to
1. A standard letter size sheet of paper or card stock is folded along the diagonal from corner to corner and creased.
2. The protruding flaps are folded over the opposing edge and creased.
3. A CD or similar-sized disk is centered on the resulting triangular shape to facilitate estimation of the location of the next fold. Alternately, the paper may be pre-marked to show the location of the next fold, or it may be “eyeballed”.
4. The narrow ends of the triangular shape are folded across the disk, or follow a marking, or by careful estimation, to create a shape that is very nearly a regular pentagon and the folds are creased. The top edges of these narrow ends are nearly flush where they overlap across the center of the pentagon.
5. The shape is unfolded as far as the first crease, which remains.
6. The narrow ends of the triangular shape are inverted by means of what may be referred to in the practice of origami as a “valley fold” so that they become located inside the main shape, with the bottom creases of the narrow ends becoming folded and creased in the opposite direction. This recreates the pentagon shape with the addition of two partial naps extending to the top of the shape, plus two chambers or pockets almost entirely separated by a layer of paper inside the main shape.
7. One disk may be inserted into each pocket.
8. The top flaps are folded over and tucked into the main shape, trapping the disk/s inside.
Alternate folds may be employed to achieve the same basic shape (i.e., pentagon); e.g., for the flaps. The product produced by the process described above has a pleasing near-perfect-pentagon shape, and readily fits a standard 5-I/4-inch CD/DVD. A feature of this design is all the edges are folds or securely tucked flaps. Additionally, the paper layer acting as a divider makes it especially suitable for disk packaging (eg., holding two disks, separated and protected from one another by the divider). As further discussed below, while US-standard 8-I/2 inch by 11 inch paper is demonstrated, European-size A4 paper or other similarly proportioned paper including custom sizes and proportions may be employed.
The cases and sleeves, and methods for making the same, of the present teachings, can be scaled up for other objects, such as for a regular vinyl LP or 45 rpm disc; or scaled down for other objects, such as for a mini-CD/DVD. It should be appreciated that the teachings herein can be adapted for most any size disk. Standard-sized paper (8-½ inches by 11 inches) may be preferred in many instances, according to various embodiments, due to its ready availability and the fact that the folding techniques taught herein and ultimate configuration of the product, are extremely well suited for standard-sized CDs and DVDs (5-1!4 inches). However, it is relatively straightforward to use other standard sizes of paper or to have paper cut to other standard or non-standard sizes, and so the present teachings extend beyond the use of standard letter-sized (8-1/2 inches×11 inches) paper. Both standard letter-sized paper and paper of other standard or non-standard sizes are contemplated herein, as when employed in accordance with the present teachings, the need/use for special cuts, perforations, tabs, gluing, and the like, is unnecessary; any and all of which can otherwise introduce undesirable complexities and complications.
The area of a CD/DVD is approximately 17.5 square inches, while in various embodiments, the area of a pentagon circumscribing a CD/DVD is approximately 20.8 square inches, for a ratio of approximately 1:1.2. In some embodiments, the ratio of the surface area of the CD/DVD to the surface area of the pentagon sleeve shape can be within a range from less than 1:1.1 to more than 1:1.3, as various embodiments contemplate tolerances of ±5% to ±10% or more.
Each reference cited herein is incorporated herein by reference in its entirety for all purposes.
While the principles of the present teachings have been illustrated in relation to various exemplary embodiments shown and described herein, the principles of the present teachings are not limited thereto and include any modifications, alternatives, variations and/or equivalents thereof.
This application claims priority to and benefit of U.S. Provisional Application Ser. No. 61/511,024, entitled “Protective Envelope for CD, DVD, Other Disc Media, or Other Discs,” filed Jul. 23, 2011.
