A METHOD AND A DEVICE FOR HOLDING A DISK-LIKE
ARTICLE
FIELD OF THE INVENTION This invention relates to a method and device for holding a disk-like article such as a compact disk (CD), digital video disk (DVD) or the like.
BACKGROUND OF THE INVENTION
There are well-known CD holders that are mainly either in the form of boxes, often called jewel boxes, normally carrying one CD, or in the form of open pocket devices usually used for holding a plurality of disks.
On the other hand, there are also known protective films for use with articles having glossy surfaces that are normally detached therefrom before operation.
For example, US 3,961,656 describes a phonograph record insulator having members that can be attached to the record and removed therefrom. The members include spacers to hold the records apart and an electrically conductive layer to help eliminate static charge buildup.
The object of the present invention is to provide a novel method for holding disk-like articles and a novel disk holder.
SUMMARY OF THE INVENTION The main idea of the present invention is to hold disk-like articles by means of a non-adhesive attachable material. A holder for disk-like articles based on this idea is light, cheap and easy to manufacture and may optionally also be capable of protecting them.
The invention provides a method for holding a disk-like article having a flat and glossy surface, such as a CD, DVD or the like, comprising providing a layer having a non-adhesive article holding surface detachably attachable to said flat and glossy surface of the article; and bringing at least a portion of said flat and glossy
surface of the article into contact with at least a portion of said article holding surface.
According to another aspect of the invention there is provided an article holder for a disk-like article having a flat and glossy surface, such as a CD, DVD or the like. The holder comprises a layer having a non-adhesive article holding surface detachably attachable to said flat and glossy surface of the article.
The term 'detachably attachable' refers to the ability of a material of being attached to, and detached from, a glossy surface of an article at least once, with attachment forces that are large enough to prevent unintentional detachment and still small enough to enable the user to easily detach the article from the holder when desired.
The term 'non-adhesive' refers to the layer's surface that does not leave traces on the article's flat and glossy surface, when the article is detached therefrom. Such layers may be attachable polymeric layers, for example, made of polyurethane, natural rubber, polyisoprene, polyvinylacetate, silicone, SBS, etc. Preferably, the article holder comprises a substrate and said layer is attached to this substrate with the layer's surface different from its article holding surface, by any appropriate means such as gluing, coating, lamination, etc. known in the art er se.
BRIEF DESCRIPTION OF THE DRAWINGS In order to understand the invention and to see how it may be carried out in practice, preferred embodiments will now be described, by way of non-limiting examples only, with reference to the accompanying drawings, in which:
Figs. 1 to 5 show holders according to different embodiments of the present invention.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Figs. 1 to 5 show holders for disk-like articles such as CDs, DVDs and the like, having a glossy mat surface. All holders include a substrate 2 and a layer 3 attached to the substrate 2. the layer having a non-adhesive article holding surface 4
facing in the direction away from the substrate 2, for holding a disk-like article by its contact with the glossy surface thereof.
The layer 3 may be made of any material that is detachably attachable to the glossy flat surface of a disk-like article. For example, it may be made of a material known to be useful as a protective film for glossy surfaces. Preferably, this material is selected from the group consisting of polyurethane natural rubber, polyisoprene, polyvinylacetate, silicone, and SBS. Most preferably the material is made of polyurethane, silicone, or polyisoprene.
The thickness of the layer 3 is chosen according to the attaching force required for holding an article. Thicker films provide for stronger attachment forces. For example, in the case of polyurethane, it has been found that films having a thickness of 60μm to 300μm are suitable, and films of 60 - 80μm thickness are preferable, for holding CDs.
The article holding surface 4 may correspond in dimensions and shape to the disk-like article to be held thereby so that the entirety of the disk surface area may be attached thereto. Alternatively, the layer area may be larger or smaller than the area of the disk-like article. In the former case, the article may be attached to the article holding surface 4 in any position, while remaining in full contact with the layer 3. In the latter case, the area of contact between the holder and the article is smaller than the article's surface area.
The substrate 2 may be of any material capable of carrying the layer 3.
Preferably, it may be made of plastic, paper or paper-board. It may bear, on one or both sides thereof, printed information that is currently presented in CD boxes, being printed on separate sheets of papers that are inserted into the boxes side by side with the disk.
The substrate's dimensions are preferably not smaller than those of the layer 3 so as to allow the layer to be fully supported by the substrate.
The holder described above may be produced as a separate product or rather may be easily integrated in other products accompanied by a disk-like article. For
example, the substrate 2 may be constituted by a page or cover of a magazine or a book, a wall of a product's package, etc.
Figures 1A, IB, and 1C show configurations of basic CD holders 10, 11 and
12 according to the present invention, having the substrate 2 and the layer 3 with the article holding surface 4.
The three holders 10, 11 and 12 differ in the shape of their article holding surfaces. The article holding surface 4 of the holder 10 has shape and dimensions similar to those of a CD it is designed to hold. The article holding surface 4 of the holder 11 has a shape of a ring with an outer perimeter substantially equal to that of the disk. The article holding surface 4 of the holder 12 has a shape of a small tag.
Such holders may, for example, be glued to a page of a book or a magazine, or inserted between pages thereof.
Fig. 2 shows a holder 20 similar to the holder 10, 11 and 12 of Figs. 1 A, IB and 1C, that additionally comprises a cover 14 to protect a CD at its side attached to the holding surface 4. The cover 14 may be made (or covered with) a protective layer which is not attachable to CDs and serves for their protection only.
Figures 3 A to 3 C illustrate a holder 30 designed for two CDs, the holder being shown at different stages of folding. This holder is comprised of two holders
10' and 10'' whose substrates (not seen) are connected. Covers 14" and 14" of the holder 30 have corresponding cut outs 16' and 16" which allow inspection of the
CDs when the holder is folded. In the holder of Figures 3 A to 3C, the holding surfaces 4' and 4" completely cover the corresponding substrates. This, however. does not necessarily need to be the case.
Fig. 4 shows an album 40 for holding a plurality of disks. The album has pages, each laminated in its entirety by a layer 3. according to the present invention.
Thus, each page may function as one large holding surface. Depending on dimensions of the pages, each page may carry one, two or more CDs 41 that may be placed anywhere thereon. The album also contains protective sheets 42 that can be either in the form of separate pages in the album or sheets attached to the substrate of the previous page at its side opposite to that carrying the layer, as in
holder 20 of Fig. 2. The album of this kind may clearly have any desired dimensions and consequently, the number of disks carried by each page thereof may vary. Also, a similar design is appropriate for a book whose pages with text are covered with a detachably attachable film so that any page may be accompanied, if needed, by a disk.
Fig. 5 shows a roll 50 of stickers, each sticker having an article holding surface 4. The article holding surfaces of this embodiment are attached to the substrate 2 in a manner similar to that in which conventional stickers are attached to their carriers. In particular, the substrate 2 may be made of silicone release paper for the article holding surfaces 4 to be attached thereto by pressure sensitive adhesive. The holding surfaces 4 may thus be separated from the substrate 2 and stuck to any desired surface.
Clearly, different variations may exist for the application of the idea of the present invention as well as different designs of holders.
