[Structure] The inner surface of the back of a cover made of polypropylene resin is roughened, and a bound object made of a polypropylene resin with a melting point similar to that of the polypropylene resin is applied to the inner surface of the back on one end surface through a molten resin having a higher melting point than the polypropylene resin. integrated with adhesive.
Description
【０００１】0001
この考案は、ポリプロピレン樹脂からなる表紙の背部内面にポリプロピレン樹 脂からなるシートの重ね合わせの端面が接着したファイルに関する。 This idea is based on polypropylene resin on the inside back of the cover made of polypropylene resin. It relates to a file in which the end surfaces of stacked sheets of oil are glued together.
【０００２】0002
ポリプロピレン樹脂からなる表紙と、この表紙に融着された合成樹脂シートを 有するファイルは、例えば実公昭５０−３５７７４号において提供されている。 しかしながら、このファイルは、表紙の背部内面に熱融着可能な合成樹脂テー プを接着剤で接着し、この上に積層した複数枚の合成樹脂シートを平面的に載置 し、シートの中央部上面を上部から下部へかけて高周波加熱用などのヒートバー によって加熱して融着するもので、シート端面で接着したものではなく、合成樹 脂シートにおいて融着部分の無駄が生じる。 A cover made of polypropylene resin and a synthetic resin sheet fused to this cover. A file containing the information is provided in, for example, Japanese Utility Model Publication No. 50-35774. However, this file has a heat-sealable synthetic resin tape on the inside back of the cover. The plastic sheet is glued with adhesive, and multiple laminated synthetic resin sheets are placed on top of it. A heat bar for high-frequency heating, etc. should be installed from the top to the bottom of the center top of the sheet. This is a material that is heated and fused by a synthetic resin, rather than one that is bonded at the edge of the sheet. The fused portion of the fat sheet is wasted.
【０００３】 ポリプロピレン樹脂からなる表紙の背部内面にポリプロピレン樹脂からなるシ ートの重ね合わせの端面を接着することができれば最も好ましく、また、この場 合にホットメルト剤すなわち、溶融樹脂の接着剤を用いることができれば、表紙 や綴じられたシートが丈夫で、また開きやすいファイルを低コストで製造するこ とができる。0003 A sheet made of polypropylene resin is placed on the inside back of the cover made of polypropylene resin. Most preferably, it is possible to glue the end faces of the overlapping sheets; If a hot-melt adhesive, that is, a molten resin adhesive, can be used, the cover It is possible to manufacture files with durable and easy-to-open bound sheets at a low cost. I can do that.
【０００４】0004
しかし現在市販されているホットメルト剤を用いて、表紙とシートを接着して も、得られたファイルは１ｍの高さからの落下テストで表紙とシートが分離する ようになり、このテストに耐え得るだけの接着強度は容易には得られなかった。 そこで、この考案の目的とするところは、ポリプロピレン樹脂からなるシート を重ね合わせた被綴じ体が、その一端面において背部内面に接着一体化されてい るファイルであって、市販されているホットメルト剤を用いて上述のテストに耐 え得る接着強度を有するファイルを提供するところにある。 However, the cover and sheet can be glued together using a hot melt agent currently available on the market. However, the cover and sheet of the obtained file were separated in a drop test from a height of 1 m. Therefore, it was not easy to obtain adhesive strength sufficient to withstand this test. Therefore, the purpose of this invention was to create a sheet made of polypropylene resin. One end of the bound object is glued and integrated with the inner surface of the back. A file that is resistant to the above test using a commercially available hot melt agent. The purpose of this invention is to provide a file with adhesive strength that can be improved.
【０００５】[0005]
上記目的達成のため、この考案においてはポリプロピレン樹脂からなる表紙の 背部内面を粗面化する手段を採用した。 In order to achieve the above purpose, this invention uses a cover made of polypropylene resin. A method was adopted to roughen the inner surface of the back.
【０００６】 すなわち、この考案に係るファイルは、ポリプロピレン樹脂からなる表紙の背 部内面が粗面化され、その内面に塗布された前記ポリプロピレン樹脂の融点より も高い温度の溶融樹脂を介し、前記ポリプロピレン樹脂と同様の融点のポリプロ ピレン樹脂からなるシートを重ね合わせた被綴じ体が、その一端面において背部 内面に接着一体化されているファイルである。[0006] In other words, the file according to this invention has a back cover made of polypropylene resin. The inner surface of the part is roughened, and the melting point of the polypropylene resin applied to the inner surface is Polypropylene resin with the same melting point as the polypropylene resin is The binding object is made by overlapping sheets made of pyrene resin, and the back side is This is a file that is integrated with adhesive on the inside.
【０００７】[0007]
上述のような構成を採ることにより、表紙の背部内面に被綴じ体が、その端面 において接着一体化されているファイルを提供することができ、接着部分の無駄 を省くことができる。 By adopting the above-mentioned configuration, the objects to be bound are placed on the inner surface of the spine of the cover, and the end surface Can provide files that are glued together, eliminating waste of glued parts can be omitted.
【０００８】 また、背部内面を粗面化した上で溶融樹脂を被着しているので接着状態が良好 で、得られたファイルは１ｍの高さから落下してもシートが分離しない強度を有 している。[0008] In addition, since the inner surface of the back is roughened and molten resin is applied, the adhesive condition is good. The resulting file has enough strength that the sheet will not separate even if dropped from a height of 1 m. are doing.
【０００９】[0009]
以下、添付図面の実施例について説明する。 Hereinafter, embodiments of the accompanying drawings will be described.
【００１０】 図１および図２は、この考案のファイルの製造手順を示したもので、ポリプロ ピレン樹脂からなる表紙１は、テーブル２上に内面を上にして置かれ、背部１ａ の内面に適当な温度に加熱された金型３が押し付けられ、金型３の下面の凹凸に よって背部１ａの内面が粗面化される手順を示している。0010 Figures 1 and 2 show the manufacturing procedure of the file of this invention. A cover 1 made of pyrene resin is placed on a table 2 with the inner surface facing up, and the back 1a The mold 3 heated to an appropriate temperature is pressed against the inner surface of the mold 3, and the unevenness of the bottom surface of the mold 3 is Therefore, the procedure for roughening the inner surface of the back portion 1a is shown.
【００１１】 粗面化された背部１ａの内面は、０．５mm程度の高さの鋭角の突起が一面に密 に分布しているような凹凸面であることが好ましい。なお、粗面化する方法とし ては図１のエンボスの例に限らず、ワイヤによる引っ掻きや粗い砥石を用いるグ ラインダによって行っても良い。[0011] The roughened inner surface of the back part 1a is densely covered with sharp protrusions with a height of about 0.5 mm. It is preferable that the surface has an uneven surface that is distributed in the following directions. In addition, as a method of roughening the surface, This is not limited to the embossing example shown in Figure 1, but also involves scratching with a wire or grinding using a coarse grindstone. It may also be done by liner.
【００１２】 このようにして粗面化した背部１ａの内面に表紙１のポリプロピレン樹脂の融 点より高い温度の溶融樹脂を塗布する。この塗布樹脂には、ポリオレフィン系、 ビニル系、アセタール系、アクリル系、スチロール系、ポリアミド系、ポリエス テル系、ポリウレタン系等の従来ホットメルト型接着剤として用いられている樹 脂が用いられる。0012 The polypropylene resin of the cover 1 is melted on the inner surface of the back 1a which has been roughened in this way. Apply molten resin at a temperature higher than the point. This coating resin includes polyolefin, Vinyl, acetal, acrylic, styrene, polyamide, polyester Wood that is conventionally used as hot-melt adhesives such as tel-based and polyurethane-based adhesives. fat is used.
【００１３】 そして、溶融樹脂の塗布は、溶融樹脂をスリットから吐出しながら、スリット と表紙１を相対的に移動させる方法で行われる。その際、塗布樹脂の温度低下を 防ぐために、熱風を吹き付けるようにすると良い。[0013] Then, the application of the molten resin is performed by discharging the molten resin from the slit. This is done by moving the cover 1 relatively. At that time, reduce the temperature of the applied resin. To prevent this, it is best to blow hot air.
【００１４】 次に図２に示すように、溶融樹脂４が塗布された背部１ａの内面に表紙１と同 様のポリプロピレン樹脂のシート（袋状や二つ折りのシートの場合を含む）の重 なり（ポリプロピレン樹脂のシートとシートの間にポリプロピレン樹脂または他 の材料からなるスペーサーシートを入れる場合も含む）からなる被綴じ体５の一 端面５ａを押し付ける。[0014] Next, as shown in FIG. 2, the inner surface of the spine 1a coated with the molten resin 4 is The weight of polypropylene resin sheets (including bag-shaped and bi-folded sheets) (There is no polypropylene resin or other material between the polypropylene resin sheets.) (including the case where a spacer sheet made of material is inserted) Press the end surface 5a.
【００１５】 この押し付けは、溶融樹脂４の温度が表紙１や被綴じ体５のシートのポリプロ ピレン樹脂の融点より高い間に行う。押し付け圧力は、５kg／cm2 以上、好まし くは１０kg／cm2 の圧力で行うのが良い。そして、溶融樹脂４が完全に凝固する まで押し付けを維持する。なお、６は被綴じ体５のシートの重なり状態を保持す る側圧板で、被綴じ体５は側圧板６で重なり状態を保持されながら表紙１の背部 １ａの内面に押し付けられる。また、被綴じ体５は押し付けの直前まで一端面５ ａを熱風の吹き付けやホットプレートとの接触などによってできるだけポリプロ ピレン樹脂の融点に近い温度に加熱されていることが好ましい。This pressing is performed while the temperature of the molten resin 4 is higher than the melting point of the polypropylene resin of the cover 1 and the sheets of the bound object 5 . The pressing pressure is preferably 5 kg/cm 2 or more, preferably 10 kg/cm 2 . Then, the pressing is maintained until the molten resin 4 is completely solidified. Reference numeral 6 denotes a side pressure plate that maintains the overlapping state of the sheets of the objects to be bound 5. The objects to be bound 5 are pressed against the inner surface of the spine 1a of the cover 1 while being held in the overlapping state by the side pressure plate 6. Further, it is preferable that one end surface 5a of the bound objects 5 is heated to a temperature as close to the melting point of the polypropylene resin as possible by blowing hot air or contacting with a hot plate until immediately before pressing.
【００１６】 以上の手順によって、図３に示したような、表紙１の背部１ａの内面に被綴じ 体５が端面を突き合わせた状態で接着しているファイルが得られ、このファイル は被綴じ体５のシートが開き易く、また１ｍの高さからの落下テストにおいても シートが分離することはない。[0016] By the above procedure, the binding material is attached to the inner surface of the spine 1a of the cover 1 as shown in Fig. 3. A file is obtained in which the body 5 is glued with the end surfaces butted together, and this file The sheets of the bound object 5 are easy to open, and even in a drop test from a height of 1 m. The sheets never separate.
【００１７】 これに対して、表紙１の背部１ａの内面を粗面化することなく、同じ条件でフ ァイルを作成した場合は、１ｍの高さからの落下テストでシートが分離するよう なファイルしか得られない。このことから、この考案のファイルは、溶融樹脂が 接着剤としてよりも加熱媒体として働き、接着は主として表紙１とシートの直接 の溶着によって行われ、そのために十分な接着強度が得られていると理解される 。[0017] On the other hand, without roughening the inner surface of the spine 1a of the cover 1, the cover 1 was removed under the same conditions. If you create a file, please make sure that the sheet separates when dropped from a height of 1m. I can only get files. From this, the file of this invention is It acts more as a heating medium than as an adhesive, and the adhesion is mainly done directly between the cover 1 and the sheet. It is understood that sufficient adhesive strength is obtained for this purpose. .
【００１８】[0018]
以上の通り、この考案によれば、市販されているようなホットメルト剤を用い て、ポリプロピレン樹脂の表紙の背部の内面にポリプロピレン樹脂のシートの重 ね合わせの一端面が接着しているファイルが得られ、しかも１ｍの高さから落下 してもシートが分離しない製品となし得たのであり、きわめて実用性の高いもの である。 As mentioned above, according to this invention, using a commercially available hot melt agent, Place a heavy polypropylene sheet on the inner surface of the spine of the polypropylene cover. A file with one end surface glued is obtained, and it can be dropped from a height of 1m. As a result, we were able to create a product that does not separate the sheets even when It is.
