BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a fixator for disc-shaped objects such as compact discs or other gramophone records, comprising two flat end plates and side portions joining these together, parallel slots being formed in the side portions, starting from one side and terminating in a semi-circular slot connecting the parallel slots, said slots being intended for the insertion and storage of objects.
DESCRIPTION OF RELATED ART
CD discs and other disc-shaped objects are normally packed and stored in plastic sleeves which leads to environmental problems in the long term. The sleeves may also crack and often cover the graphic printing on the disc. It is also often difficult to them to open without some practice. A material is sought which can easily be burned after use without leading to environmental problems, where the packed product is easily visible and which at the same time provides a durable and inexpensive wrapping.
SUMMARY OF THE INVENTION
The invention constitutes a solution to these and other associated problems and is characterized in that the side portions comprise at least two layers encompassing the outer sides of the slots, an upper layer in contact with the outer edge of the disc and forming the bottom of the slot, and a layer arranged below the upper layer and in contact with the outermost peripheral parts of the disc not consisting of recorded parts of the disc, said layers being designed, together with an upper end plate, to clamp a disc that has been inserted.
As mentioned above, this fixator may constitute part of a wrapper, such as the sleeve of a CD disc. The object, which may be a CD disc, is stored with its recorded part a certain distance from the uninterrupted bottom end plate and can therefore be kept free from dirt particles, scratches and the like which might cause disturbance when playing the disc. The upper end plate can be provided with a central opening clearly showing the label on the disc. Fixation will be durable and secure. By making the slot marginally narrower than the disc and its thickness marginally less than the thickness of the disc, the object is "clamped" firmly and the fixator is durable and secure. No damaging waste gases are obtained when this fixator is burned, as would be the case if it were made of plastic.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a top plan view of a fixator according to the invention with a disc inserted;
FIG. 2 is a top plan view of a fixator according to the invention with a disc partially withdrawn;
FIG. 3 is a perspective view of the fixator of the invention;
FIG. 4 is a cross-sectional view of the fixator of FIG. 3; and
FIGS. 5A-5D are top plan views of each layer of the fixator of the invention.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 shows an object (2), such as a CD disc, inserted in a fixator (1) according to the invention and FIG. 2 shows the same disc partially withdrawn. As can be seen, the uppermost end plate is provided with a central opening which fully reveals the label, and one or two open parts (3, 4) extend from this opening to the periphery. These facilitate insertion and withdrawal of the disc.
FIG. 3 shows a fixator according to the invention (with no disc inserted). It consists of an uninterrupted bottom end plate (6) and an upper end plate (5) provided with an opening (9), see also FIGS. 1 and 2. These end plates are joined by side portions, in this case two layers (7, 8). The lower bottom end plate is also shown in FIG. 5A and the upper end plate in FIG. 5D.
Two parallel slots (10) are formed in the side layers (7, 8), see also FIG. 5C, terminating in a semi-circular slot (11). The disc shall be inserted in this slot (10, 11) and the shape of the slot is also shown in FIG. 4. It is formed by a side layer (8) which shall abut against the periphery of the disc and form the deepest part of the slot (10, 11). A second side layer (7) is arranged beneath the first layer, which shall rest against the outer edge of the disc, i.e. against the unrecorded parts of the disc, see
