JP3579653B2 - Protector for recording disk - Google Patents

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a recording disk protector.
[0002]
[Prior art]
Conventionally, recording disks such as CDs and DVDs have been stored in a case. The printing performed on the surface of the recording disk was silk-screen printing.
[0003]
[Problems to be solved by the invention]
However, there is a fear that the recording holding portion of the recording disk may be inadvertently hit against the case when the recording disk is taken in and out of the case, thereby damaging the recording holding portion of the recording disk. Further, there is a disadvantage that the case requires a large storage space for the recording disk. Also, printing by silk screen was easy to peel off.
[0004]
Therefore, an object of the present invention is to provide a protector for a recording disk which does not have a risk of damaging a recording holding portion of the recording disk and requires a small storage space for the recording disk.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, a recording disk protector according to the present invention is provided with a substantially rectangular parallelepiped independent small projection on one surface of a transparent and flat plastic basic sheet that is printed and uniformly. A transparent pressure-sensitive adhesive layer having a large number and having a recording surface of a recording disk that is adhered to the recording surface so as to be separable, is provided, and the outer diameter is a circle slightly larger than the outer diameter of the recording disk, and on the outer periphery. At least one peeling protruding piece is provided, and a groove is formed between the adjacent substantially rectangular parallelepiped independent small protruding parts for allowing gas to escape to the outside in a lattice shape. Further, a transparent release sheet is laminated.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the drawings showing the embodiments.
[0007]
FIG. 1 shows a use state of the first embodiment of the present invention. The recording disk protector is used by being detachably attached to a recording disk R such as a CD or DVD. Specifically, it is preferable to sell, store, or the like in a state where it is attached to the recording disk R. The recording disk protectors has an outer diameter W is a circular slightly larger dimension than the outer diameter W ₁ of the record disc R.
[0008]
FIG. 2 shows a protector for a recording disk. Reference numeral 1 denotes a peeling projection provided on the outer periphery of the recording disk protector. In the present embodiment, one is provided.
[0009]
FIG. 3 shows a state in which the recording disk protector is attached to the recording disk R. More specifically, as shown in FIG. 3A, the recording holding portion M of the recording disk R is attached in a covering shape in the direction of the arrow Y. FIG. 3B shows a state in which the recording disk protector is attached.
[0010]
Since the recording disk protector is configured to cover the entire recording holding portion M of the recording disk R, it is possible to prevent the recording holding portion M from being damaged and to eliminate the need for a case because the case becomes unnecessary. It can be easily stored in the storage area, making it easy to carry.
[0011]
As shown in FIGS. 4 and 5, the protector body 2 of the protector for a recording disk of the present invention includes a base sheet 3 made of a transparent plastic (for example, PET, that is, polyethylene terephthalate), and one surface of the plastic base sheet 3. The recording surface R ₁ of the recording disk R having a large number of independent small projections 4..., That is, the surface on which information is recorded among the upper and lower surfaces of the recording disk R. See FIG. And a transparent pressure-sensitive adhesive layer 6 which is adhered so as to be separable. The pressure-sensitive adhesive layer 6 is made of, for example, a urethane-based pressure-sensitive adhesive.
[0012]
The independent small protrusion 4 is formed in a substantially rectangular parallelepiped. Grooves 7 are formed between the independent small protrusions 4 in a grid pattern (as shown in FIG. 5).
[0013]
FIG. 6 shows a second embodiment. That is, in this protector for a recording disk, a transparent release sheet 8 made of PET is laminated on the lower surface 2a of the protector body 2. Since the release sheet 8 is transparent, the printing is enhanced when printing is performed on the upper surface of the recording disk protector (as shown in FIG. 7 described later). In order to use the recording disk protector, the release sheet 8 is peeled off and then attached to the recording surface R ₁ (see FIG. 3) of the recording disk R (similar to the first embodiment). use. With the release sheet 8 laminated, a protector for a recording disk can be sold.
[0014]
FIG. 7 shows a use state of the third embodiment, in which the basic sheet 3 and the pressure-sensitive adhesive layer 6 are transparent, and the upper surface 3b of the basic sheet 3 is printed (P indicates ink). . For example, an advertisement is printed by offset printing. The printing can be a design according to preference. The printing, when going to the only part of the upper surface of the base sheet 3, at the semi-transparent ink P, in use, silver gloss of the recording surface R ₁ is seen through. That is, since the protector body 2 is transparent, even more beautiful light is reflected on the recording surface R ₁ of the record disc R.
[0015]
8 and 9 show a reference example of the recording disk R. The record disc R is a non-recording surface R _2, is bonded or welded to record disc label L. The label L is obtained by performing offset printing on one surface 10a of a label body 10 made of a polycarbonate film (P indicates ink). Other surface 10b of the label body 10 is bonded or welded to the non-recording surface R ₂ of the record disc R (11 illustrates the adhesive layer or the welding layer). The label L is a circle whose outer diameter W ₀ is the same as or slightly smaller than the outer diameter of the recording disk R.
[0016]
In the present invention, the design can be freely changed, and two or more peel-off projections 1 may be provided on the outer periphery of the recording disk protector. Further, the material of the pressure-sensitive adhesive layer 6 may be other than the urethane-based pressure-sensitive adhesive. The release sheet 8 may be opaque.
[0017]
Further, it is also preferable that the release sheet 8 has a small concave portion corresponding to the independent small protrusion 4 of the adhesive layer 6. In this case, since there is no gap between the release sheet 8 and the pressure-sensitive adhesive layer 6, the sealing performance is maintained, and the deterioration of the pressure-sensitive adhesive ability of the pressure-sensitive adhesive layer 6 can be prevented.
[0018]
【The invention's effect】
The present invention is configured as described above, and has the following effects.
[0019]
According to the first aspect, no case is required, and the information recorded on the recording disk R can be protected. Compared to the case where the recording disks R are stored in a case, the thickness and the size when stored (when used) are extremely thin, so that even a large number of recording disks R are bulky and easy to handle.
[0020]
Further, when gas is generated, the gas can escape to the outside from the groove 7 between the independent small projections 4..., And there is no possibility that the recording surface R ₁ of the recording disk R is damaged, and the information is protected. You. Further, since the recording surface R ₁ of the record disc R freely adhesive separation, can be used repeatedly, it is convenient.
[0021]
Further, since the outer diameter W is circular slightly larger dimension than the outer diameter W ₁ of the record disc R, it can be protected reliably from the outside of the recording holding portion M of the record disc R. That is, the information recorded on the recording disk R can be reliably protected. Further, the peeling-off projection 1 can easily and reliably perform the adhesive separation from the recording disk R.
[0022]
Further, since the basic sheet 3 and the adhesive layer 6 transparent, and silvery reflection recording surface R ₁ of the record disc R, beautiful record disc R and the recording disk protectors.
According to the second aspect, the colors of the base sheet 3 and the pressure-sensitive adhesive layer 6 can be easily confirmed.
