FIG. 1 is a plan view showing an overall configuration example of a compact disc protective jacket according to the present invention, FIG. 2 is a perspective view of the compact disc protective jacket in FIG. 1 in a folded state, and FIG. 3 is FIG. FIG. 3 is an overall perspective view showing a state in which the compact disc protective jacket in FIG.

That is, as shown in FIG. 1, the protective jacket for a compact disc of the present embodiment has one side attached to the front or back cover of a book, and from each side having a length larger than the diameter of the compact disc. Consisting of a substantially square support piece 1 made of paper and paperboard or cardboard that is equal to or slightly thicker than the thickness of the compact disc, and the U-shaped arc portion is larger than the diameter of the compact disc and the U-shaped opening portion. Is larger than the diameter of the compact disc, and is connected to the U-shaped member 2 attached to the other surface side of the support piece 1 and the side piece of the U-shaped opening portion of the support piece 1 through the bent portion 3. At the same time, a cut line 4 connecting the diagonal lines is provided in a substantially triangular shape with the bent portion 3 as one side, and after the compact disc is stored, the cut line 4 is folded and adhered to the U-shaped member 2 at the bent portion 3. , Support piece 1 And a folding piece 5 made of paper and having substantially the same size.

Then, the compact disc 6 is housed in the U-shaped portion of the protective jacket for a compact disc having this structure, and one side of the support piece 1 of the protective jacket is attached to the front or back cover 7a of the book 7. By doing so, the compact disc 6 is attached to the book 7.

Here, as the material of the supporting piece 1 and the folding piece 5, paper having a certain degree of rigidity (about 100 g / m ² to 150 g / m ² ) necessary for accommodating the compact disc (for example, high-quality paper) is used. Paper) is used. Further, the U-shaped member 2 prevents the compact disc 6 from being loaded on the compact disc 6 when the compact disc 6 is stored in the compact disc protective jacket and is bound to a book 7 such as a magazine (described later). It is equivalent to a "pillow" for doing.

Next, a method of using the compact disc protective jacket of the present embodiment having the above-described configuration will be described.

When the compact disc is to be stored in the compact disc protective jacket, the compact disc 6 is stored in the U-shaped portion of the U-shaped member 2 on the support piece 1.

Next, after the compact disc 6 is housed, the bending portion 3 is bent, and the folding piece 5 is attached to the U-shaped member 2 by folding and folding the compact disc 6 to protect the compact disc. Enclosed in the jacket. As a result, the protective jacket for the compact disc becomes a pocket-shaped bag that encloses the compact disc 6. FIG. 2 is a perspective view showing the state.

Next, as shown in FIG. 3, one side of the supporting piece 1 of the protective jacket for a compact disc, on which the compact disc 6 is set, is attached to the front or back cover 7a of the book 7, as shown in FIG. It is attached to the book 7 by wearing it.

On the other hand, when the reader (user) reproduces the compact disc 6 in the state as shown in FIG. 3, the score line 4 is made of continuous small holes (perforations, perforations, etc.) for cutting. By cutting open, a compact disc storage bag having the cut line 4 as an access port is provided, and the compact disc 6 can be unsealed from the seal of the compact disc protective jacket.

On the other hand, in the compact disc protective jacket of this embodiment, since the protective jacket body is made of paper, it is extremely inexpensive and the cost of the compact disc 6 can be reduced. This allows the compact disc to be securely stored and protected without the use of expensive and sturdy plastic storage cases.

Further, since the protective jacket body is made of paper, the protective jacket itself is extremely light in weight and thin in thickness, so that the storage space is small. As a result, the volume of the book 7 remains almost unchanged between the case where the compact disc 6 is attached to the book 7 and the case where the compact disc 6 is not attached, so that the distribution cost of the book 7 is reduced and the list price of the book can be reduced.

Further, in the U-shaped member 2, the U-shaped arc portion is larger than the diameter of the compact disc 6 and the U-shaped opening portion is larger than the diameter of the compact disc 6, so that When the compact disc 6 is taken in and out, the compact disc 6 can be taken in and out very easily by opening the score line 4 existing in the folding piece 5.

Furthermore, since the U-shaped member 2 is made of paperboard or cardboard that is equal to the thickness (1.2 mm) of the compact disc 6 or slightly thick (1.2 mm + α), The central portion, that is, the signal reading portion (signal engraving portion) is not scratched and the performance of the compact disc 7 is not impaired.

As described above, the protective jacket for a compact disc of this embodiment has one side attached to the front or back cover of a book and is composed of each side having a length larger than the diameter of the compact disc 6. , A substantially square support piece 1 made of paper, which has a certain degree of rigidity required to accommodate the compact disc 6, and a paperboard or cardboard which is equal to or slightly thicker than the thickness of the compact disc 6, and has a U-shaped arc. The U-shaped member 2 affixed to the other surface of the support piece 1 having a portion larger than the diameter of the compact disc 6 and a U-shaped opening portion larger than the diameter of the compact disc 6, and the support piece 1. The U-shaped opening side piece is connected to the side piece through the bent portion 3, and the cut line 4 connecting the diagonal lines is provided in a substantially triangular shape with the bent portion 3 as one side. After being stored, the support piece 1 and the folded piece 5 made of paper and having substantially the same dimensions are formed by folding and adhering on the U-shaped member 2 at the bent portion 3.

Therefore, the following various operational effects can be obtained.

(A) Since it is made of paper, the manufacturing cost is low, and the configuration is slightly thicker than the disc thickness (1.2 mm) (1.2 mm + α), which is extremely simple.

(B) Since the protective jacket body is made of paper, it is possible to make a protective jacket that is extremely lightweight and has a small thickness, and the storage space is small.

(C) When the books 7 are stacked, a load is applied to the U-shaped members 2 of the paperboard, so that the compact disk 6 is not inserted in the compact disk 6 even though the compact disk 6 is sandwiched between the books 7. The load is not applied, the compact disc 6 is not damaged, and the performance is not deteriorated. As a result, the compact disc 6 can be securely stored and protected without using an expensive and sturdy plastic storage case as in the conventional case.

(D) The compact disc 6 may be wrapped in the protective jacket for the compact disc and then attached to the book 7, or the protective jacket for the compact disc may be attached to the book 7 and then the compact disc 6 may be attached. It is also possible to store. In this case, it is particularly advantageous in terms of the process to seal the compact disc 6 in advance in the protective jacket for the compact disc.

(E) The reader removes the compact disc 6 from the protective jacket for the compact disc after purchasing the book 7, so that the compact disc 6 can be protected at the distribution stage, and can be lost due to being dropped or stolen at a bookstore. The role of prevention (on the contrary, the reader (user) of the book 7 can know that the compact disc 6 is new by opening the slit line 4 to open it by himself) It is also possible to use the protective jacket for this compact disc as a bag for storage.

(F) Up to now, books with compact discs have a bulky storage case for compact discs, so it is hard to tell whether they are compact discs with books or compact discs with books. In the disc protection jacket, even though the compact disc 6 is attached, the volume (volume) of one book is almost the same as before, so the distribution form to the book agency is the same as before. Therefore, the distribution cost does not increase, and the impact on the book price is extremely small.

(G) It becomes possible to attach the compact disc 6 to a book 7 such as a magazine by reducing the ratio of the cost of the compact disc 6 to the storage body as much as possible.

In the above embodiments, the case where the present invention is applied to a compact disc has been described, but the present invention is not limited to this, and the same effect can be obtained by applying the present invention to an optical video disc. Is something that can be done.

Further, in the above embodiment, the case where the high quality paper is used as the material of the protective jacket body has been described, but the material is not limited to this, and is made of a paper having a certain degree of rigidity necessary for housing a compact disc, for example. Anything will do.

Further, in the above-mentioned embodiment, by providing a tongue which serves as a grip portion when the compact disc is put in and out, at the apex portion of the triangle of the folded piece 5, the cutting work of the score line 4 is performed. Can be performed more easily.

On the other hand, in the above embodiment, the case where the support piece 1 and the folding piece 5 are configured as separate bodies has been described, but the present invention is not limited to this, and a supporting piece in which the support piece and the folding piece are integrated is used. For example, as shown in a development view in FIG. 4, a rectangular sheet having a short side having a length larger than the diameter of the compact disc 6 and a long side having a length almost twice the short side is used. , A bent portion 3 that connects each long side substantially at its center is provided, and one piece bisected by the bent portion 3 is used as a folded piece 5, and a score line 4 that connects diagonal lines of the folded piece 5 Alternatively, a supporting piece 8 formed in a substantially triangular shape having the bent portion 3 as one side may be used.

In addition, in the above-described embodiment, the case where the U-shaped member is used has been described, but the present invention is not limited to this, and may be any shape that can fulfill its function, such as a concave member. The shape is called U-shape including the shape.
