がり、使用に耐えなくなるという欠点があつた。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a binder or file cover. Binders and files are document organizing supplies used to bind and organize documents, and some manufacturers include binders in the category of files without distinguishing between binders and files. They have almost the same functions. By the way, resin-coated paper, which is made by covering cardboard with a resin sheet, is used for the cover of these binders and files, but in conventional paper, resin sheets are placed on both sides of cardboard or other cardboard that serves as the core material. The paper is fused between the peripheral edges of the sheet, and the strength is low because the cardboard and resin sheet are not tightly bonded.Also, since the interior of the sheet is under reduced pressure during fusion, the resin The problem was that if the sheet got scratched, it would suck in air and swell up, making it unusable.
そこで、樹脂シートと厚紙とを接着剤で接着し
ておくことが提案されているが、製品化後、高温
中に放置されると、接着剤塗布の際に厚紙に泌み
込んだ水分が気化して、樹脂シートをふくれあが

のとはいえない。 Therefore, it has been proposed to bond the resin sheet and cardboard with adhesive, but if the product is left in a high temperature environment, the moisture seeped into the cardboard during the application of the adhesive will become airborne. This has the disadvantage of causing the resin sheet to swell, and is not necessarily desirable.

表紙を提供したものである。 The present invention was made in view of such circumstances, and resin sheets that are slightly larger than the cardboard and whose peripheral edges protrude outward from the cardboard are placed on both sides of the cardboard coated with an adhesive, and are pressed together. High strength is achieved by bonding the resin sheet and cardboard with adhesive, fusing the peripheral edges of the resin sheet, and drilling a large number of micropores from at least one side of the resin sheet whose tips reach inside the cardboard. The present invention provides a cover for a binder or file made of resin-coated paper that is large and does not bulge.

宜の加熱手段によつて互いに融着されている。 FIG. 1 is a sectional view showing an example of resin-coated paper constituting the cover of the binder or file of the present invention, and FIG. 2 is a partially enlarged view thereof. In the drawings, 1 is a thick paper such as cardboard, and 2 and 3 are resin sheets such as vinyl chloride resin sheets. 4 is an adhesive layer that adheres the resin sheets 2 and 3 and the cardboard 1; 5 is a microhole drilled from the resin sheet 2 side to the cardboard 1 side; the tip of this microhole 5 is inside the cardboard 1; has reached. Note that the micropores 5 are so small that they cannot be seen with the naked eye. The resin sheets 2 and 3 are slightly larger than the cardboard 1, and the peripheral edges 2a and 3a projecting outward from the cardboard 1 are fused together by appropriate heating means such as high-frequency heating. There is.

and the resin sheets 2 and 3 are pressed together, and the resin sheets 2 and 3 and the cardboard 1 are bonded together with an adhesive. After properly drying in this state, as shown in Figure 4, the base 1

Press the resin sheet 2 with the pressure member 12 at a pressure of cm 2 , press the upper resin sheet 2, cardboard 1, and lower resin sheet 3, and bond the resin sheets 2, 3 and cardboard 1 with adhesive. In this state, the peripheral edges 2a, 3a of the resin sheets 2, 3 are held between the electrode portion 14 at the end of the pressure member 12 and the base 11 and heated under high frequency to heat the resin sheets 2, 3. The peripheral edges 2a and 3a of the wafer are fused together.

１上に針を設けるなどによつて、前記と同様につ
くられる。 FIG. 3 is a partially enlarged sectional view showing another example of resin-coated paper constituting the binder or file cover of the present invention. In this resin-coated paper, the micropores 5 are formed in both resin sheets, that is, in the upper It is opened both from the resin sheet 2 side and from the lower resin sheet 3 side. Then, such a resin-coated paper with micropores 5 formed on both sides can be used, for example, as the substrate 1 described above.
It is made in the same manner as described above, such as by providing a needle on 1.
本発明において、微孔５を少なくとも一方の樹
脂シート側からあけるとしたのは、厚紙１内部は
多少気体の流通性があるので、微孔５を一方から
あけておけば、あえて両側からあけなくても、樹
脂シートのふくれをほぼ完全に防止できるからで
ある。しかし、第３図に示すように両側から微孔
をあけておくことが好ましいことはもちろんであ
る。 In the present invention, the reason why the micropores 5 are opened from at least one side of the resin sheet is because there is some gas circulation inside the cardboard 1, so if the micropores 5 are opened from one side, it is not necessary to open them from both sides. This is because the blistering of the resin sheet can be almost completely prevented. However, it is of course preferable to make micropores from both sides as shown in FIG.
なお前記の製造例では微孔をあけながら樹脂シ
ートの周縁部間の融着を行なつたが、微孔は融着
にさきだつてあけておいてもよいし、また融着後
にあけてもよい。しかし前記製造例のように微孔

う方が工程が簡略化できるし、また融着時の加熱

た状態で微孔をあけるので、孔があけやすく、か
つあけた孔が冷却後に収縮して小さくなるので、
前記樹脂被覆紙の製造に際してとくに好適であ
る。 In the above production example, the resin sheets were fused together while making micropores, but the micropores may be made prior to the fusion or after the fusion. . However, the process can be simplified by fusing the peripheral edges of the resin sheet while making micropores as in the above manufacturing example, and the resin sheet becomes somewhat soft and elongated due to the heating during fusing. Since micropores are drilled using the method, the holes are easy to drill, and the drilled holes shrink and become smaller after cooling.
It is particularly suitable for producing the resin-coated paper.

の面での経済的効果も非常に大きい。 According to the binder or file cover of the present invention made of such resin-coated paper, it is possible to almost completely prevent the resin sheet from blistering, and the resin sheet and the cardboard are strongly bonded with the adhesive. As a result, the overall strength is improved,
The thickness of the resin sheet used can be reduced. For example, if the resin sheet and cardboard were not bonded together as in the past, it was necessary to use a vinyl chloride resin sheet with a thickness of 0.3 to 0.4 mm, but according to the present invention, the thickness is approximately 0.05 to 0.2 mm. In addition to preventing blisters as mentioned above, the economic effect in this respect is also very large.

などの面から好ましい。 The adhesive used in the present invention is preferably, for example, a vinyl acetate adhesive. However, it is not limited to this. The micropores 5 formed in the resin sheet have a diameter of about 50 μm, which is extremely small and cannot be seen with the naked eye. The more micropores there are, the more convenient it is to prevent the resin sheet from blistering, but if there are too many, the strength of the resin sheet will decrease, so it is recommended to have 25 or more micropores per square meter, especially 40 or more.
It is preferable to use around 50 pieces. Note that as the resin sheet, one having a leather-like uneven pattern formed on the surface, which is usually called leather, is preferable from the viewpoint of texture and visual appearance.
