Abstract

PURPOSE:To prevent such inconvenient cases where a cassette label swells up and then comes off or the label is broken during its resticking process by using a PET (polyethylene terephthalate) foam as the material of the labels stuck to the tape cassettes, etc. CONSTITUTION:A label 2 stuck on the surface of a tape cassette casing 1, etc., is made of the PET foam sheet which has substantially no water absorbing property and the satisfactory strength compared with the paper. Thus the label 2 never swells up nor comes off from the tape cassette and furthermore is never broken during its resticking process. In addition, the PET foam sheet excels in the cost properties since it is less expensive than an aluminum foil.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a label affixed to a tape cassette or the like.

[Summary of the Invention] The present invention uses foamed PET (polyethylene terephthalate) as a material for labels attached to tape cassettes, etc., so that the labels do not become soft and peel off, or break during peeling when replacing the label. This is so that you don't have to relax.

[Prior Art] Generally, in a tape cassette or the like, a label is attached to the surface of the casing, and a title or the like can be written on the label.

Figure 1 shows an example of a compact audio cassette. In this cassette, a band-shaped label (2
). In the case of this compact cassette, the label (2) can be replaced; that is, when the recorded contents of the tape cassette are changed, the label can be peeled off and a label with a new title written on it can be pasted.

Fig. 2 is an example of a so-called micro cassette. In this cassette, a label (2) is pasted on almost the entire surface of both the upper and lower surfaces of the cassette case (1), and a title, etc. is written on this label (2). (In the case of this microcassette, the -g label is not replaced).

[Problem to be solved by the invention]

Traditionally, most of these labels are made of paper, so after a while after being pasted on the tape cassette, they absorb moisture and become soft, and some of the labels start to peel off with parts lifting up. However, there are problems such as it often breaks in the middle.

In addition, some labels for microcassettes are made of aluminum foil, but in this case the material cost is high and is disadvantageous in terms of cost.

The present invention has been made in view of these points, and aims to solve the above-mentioned problems by considering the material of the label.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention provides a label to be attached to the surface of a casing such as a tape cassette, which is formed from a foamed PET sheet.

[Effect]

Foamed PET sheets have almost no water absorption and are sufficiently strong compared to Gion, so they won't get soggy and peel off after being pasted on the tape cassette, and they won't break while being peeled off when replacing the label. I don't have to worry about it. Also, foaming P
Since ET sheet is cheaper than aluminum foil, it is also advantageous in terms of cost.

〔Example〕

Examples of the present invention will be described below.

The present invention is to use a foamed PET sheet as a material for a label to be attached to a tape cassette.

That is, the inventors of the present invention have investigated various label materials to replace conventional paper and aluminum foil, and have discovered that foamed PET is the most suitable material as it has almost no water absorption and has sufficient resistance. be.

This foamed PET sheet is made by foaming PET (polyethylene terephthalate) and molding it into a sheet shape, and there are countless fine air bubbles of about 1 μm inside the sheet. These air bubbles make the label opaque, which means it takes on a white appearance similar to paper; PET is usually colorless and transparent.)
Also, due to the elasticity of the bubbles, the writing properties are good and titles, etc. can be written easily. Furthermore, since the foamed PET sheet has good adhesion properties, sufficient adhesion to the tape cassette can be ensured.

The thickness of this foamed PET sheet label is 50 to 150μ- when used as a label for a compact cassette as shown in Figure 1, and 50 to 350μ- when used as a label for a micro cassette as shown in Figure 2. The density of each label is 0.7 to 0.95 g/cm' in consideration of the sealability (opacity) and writability of the label. Furthermore, by roughening the surface of the label, the writing properties can be further improved.

And since this foamed PET sheet has almost no water absorption,
The label does not soak up moisture and become soft after it is applied to the tape cassette, and therefore does not peel off like a part of the label does in the past, so it is possible to maintain a stable label attachment condition at all times.

Also, foamed PET sheets have sufficient strength (durability) compared to paper.
Therefore, there is no chance of the label being cut midway through when it is removed from the tape cassette when replacing the label.

Furthermore, since the foamed PET sheet has excellent weather resistance, there is no risk of discoloration caused by ultraviolet rays even after a long period of time.

Furthermore, since the foamed PET sheet has a higher quality feel than conventional paper in terms of gloss, color tone, etc., it is possible to improve the marketability of the tape cassette.

Furthermore, since the foamed PET sheet is cheaper (less than 172 mm) than the aluminum foil conventionally used in microcassettes, it is advantageous in terms of cost because the material cost can be kept low.

Although the embodiments of the present invention have been described above, the present invention is not limited to labels for compact cassettes and micro cassettes shown in the figures, but can also be applied to labels for various tape cassettes such as bidet cassettes, and labels for disc cartridges. It can also be widely applied to labels, etc.

〔Effect of the invention〕

As is clear from the above explanation, because the label of the present invention uses a foamed PET sheet as its material, it will not become soft and peel off after being applied to a tape cassette, etc., and it will not peel off when reapplying the label. There is no risk of it breaking. In addition, it does not discolor due to ultraviolet rays, and has a more luxurious feel compared to paper, improving the marketability of tape cassettes, etc. Furthermore, it is cheaper than aluminum foil, so it is cost-effective. It has no good practical effect.
