巻き重ね時に潰れないように、強度が高いために、廃棄
処分にする場合に、踏みつけたくらいでは潰すことがで
きず、嵩張って廃棄し難く、またリサイクルも容易に行
えないという問題があった。At business establishments that use a large amount of these roll products, a large amount of used paper tubes accumulate, and the paper tubes are
Because of its high strength so that it will not be crushed when rolled up, there is a problem that when it is discarded, it cannot be crushed even if it is stepped on, it is bulky and difficult to discard, and it cannot be easily recycled. .

【発明が解決しようとする課題】前記の問題点を解消す
るために、巻き始めの部分、即ち、ロール製品の中心部
分では、巻き重ね密度を高くし、この密度の高い中心部
を巻芯にして、前記プラスチックフィルムを巻き重ねた
コアレスのロール製品が考案されている。In order to solve the above problems, at the beginning of winding, that is, at the center of the roll product, the winding density is increased, and the center with high density is used as the core. As a result, a coreless roll product in which the plastic film is wound is devised.

巻き付けるという作業が難しくなる問題もあった。[0006] In this coreless roll product, the wound films are often in close contact with each other at the high-density central part, and the film cannot be used up to the end, and the film in that part is wasted. Further, the coreless roll product has a problem that the shape retaining property of the film becomes poor at the end of use, which makes it difficult to wind the film around the product while pulling the film.
【０００７】そこで、この発明の課題は、巻芯に紙管を
使用せず、使用後の巻芯の廃棄を困難なく行うことがで

無駄なく使用できるロール製品を提供することである。Therefore, an object of the present invention is to use a paper core as a core, to dispose of a core after use without difficulty, and to waste a long sheet or film wound up to the end. The purpose is to provide roll products that can be used.
【０００８】[0008]
【課題を解決するための手段】前記の課題を解決するた
めに、この発明では以下の構成を採用したのである。In order to solve the above problems, the present invention adopts the following configuration.
【０００９】巻芯上に、長尺のシートまたはフィルムを
巻き重ねたロール製品において、平板状に展開可能な材
質からなる平板を円筒形に湾曲させ、この湾曲させた平
板の両側辺の間に間隙をもたせて、前記巻芯を形成した
のである。In a roll product in which a long sheet or film is wound around a winding core, a flat plate made of a material that can be spread in a flat plate shape is curved into a cylindrical shape, and between the both sides of the curved flat plate. The winding core is formed with a gap.
【００１０】このように、平板状に展開可能な材質から
なる平板を円筒形に湾曲させて巻芯にするので、使用後
は平板状態に戻すことができ、従来の紙管のように、使
用後は嵩張らずに、廃棄や再生を容易に行うことができ
る。In this way, since the flat plate made of a material that can be expanded into a flat plate is curved into a cylindrical shape to form a core, it can be returned to the flat plate state after use, and it can be used like a conventional paper tube. After that, it can be easily discarded or regenerated without being bulky.
【００１１】また、前記平板の材質として、所要の強
度、即ちこわさを有するものを選択することにより、シ
ートまたはフィルムを巻き重ねた状態で、円筒形に湾曲
させた平板が巻芯として必要な保形性を有する。Further, by selecting a material having a required strength, that is, a rigidity, as the material of the flat plate, a flat plate curved in a cylindrical shape in a state in which sheets or films are wound is required as a core. Has formality.
【００１２】そして、巻き重ねたシートまたはフィルム

ムを引き出す過程で、巻芯が円筒形状を保ち、その内径
が小さくなることを防止できる。Then, the rolled sheet or film enters the gap between the both sides of the flat plate, and the interposition of the sheet or film prevents the displacement of the both sides in the circumferential direction. Alternatively, it is possible to prevent the winding core from keeping a cylindrical shape and reducing the inner diameter in the process of pulling out the film.
【００１３】それにより、使い終わりに近づいても、巻
き重ねたシートまたはフィルムが巻芯に沿って保形さ

きる。As a result, even after the end of use, the wound sheet or film retains its shape along the core, and can be used up with a tensile force applied to the end.
【００１４】巻芯上に、長尺のシートまたはフィルムを
巻き重ねたロール製品において、平板状に展開可能な材
質からなる平板を円筒形に湾曲させ、この湾曲させた平
板の両側辺が突き合うようにして、前記巻芯を形成する
こともできる。In a roll product in which a long sheet or film is wound around a winding core, a flat plate made of a material that can be expanded into a flat plate is curved into a cylindrical shape, and both sides of the curved flat plate are butted against each other. In this way, the core can be formed.
【００１５】このように、円筒形に湾曲させた平板の両
側辺を突き合わると、接着剤等を用いて両側辺を接合し
ていなくても、この両側辺が互いに滑らず、上記の場合
と同様に、巻き重ね終了後に、シートまたはフィルムを
引き出す過程で、巻芯が円筒形状を保ち、その内径が小
さくなることを防止できる。In this case, when the both sides of the flat plate curved in a cylindrical shape are abutted against each other, the both sides do not slide with each other even if the both sides are not joined by using an adhesive or the like. Similarly to the above, it is possible to prevent the core from having a cylindrical shape and having a smaller inner diameter in the process of pulling out the sheet or film after the completion of winding.
【００１６】円筒形に湾曲させた前記平板の両側辺の間
から、前記のシートまたはフィルムの巻き始め部分を前
記円筒形内に咬み込ませて、巻き重ねることができる。It is possible to wind the sheet or the film at the beginning of winding of the sheet or film into the cylindrical shape from between both sides of the flat plate which is curved in a cylindrical shape, and to wind the sheet or film.

が妨げられ、巻き重ね終了後に、シートまたはフィルム
を引き出す過程で、巻芯が円筒形状を保ち、その内径が
小さくならず、かつ、巻芯が軸方向に移動することを防
止できる。As described above, when the sheet or film is bitten into the cylindrical shape from the both sides of the flat plate curved in the cylindrical shape, the interposition of the sheet or film serves as a slip stopper. Displacement of the both sides in the circumferential direction is hindered, and after the completion of winding the sheet or film, the core keeps a cylindrical shape and the inner diameter does not decrease, and the core moves in the axial direction. Can be prevented.

巻き重ねることができる。Further, by virtue of the interposition of the above-mentioned sheet or film, the friction force acting between the winding start portion and the flat plate and the core metal of the winding machine does not prevent the core from being fixed to the core with an adhesive or the like. However, sheets and films can be wrapped without slipping.
【００１９】そして、前記平板を、厚紙によって形成す

述のように、廃棄や再生を容易に行うことができる。In general, as the thickness of paper increases,
Since stiffness increases, if cardboard is used as the flat plate,
The required shape retention property as a winding core can be realized, and after use, it can be easily developed into a flat plate shape, and as described above, it can be easily discarded or regenerated.

ることができる。In addition, a gap is provided between both sides of a flat plate curved in a cylindrical shape so that a wound sheet or film can enter the gap, or the both sides can be butted against each other. Alternatively, by making the winding start portion of the sheet or film bite into the cylindrical shape or the like so that both sides of the flat plate do not slip with each other, an adhesive or the like does not have to join the both sides. It has the required shape retention as a core, and the inner diameter of the core becomes smaller in the process of pulling out and using the sheet or film after the completion of winding, and in the axial direction of the core. It is possible to prevent the movement of the sheet, and it is possible to use up a long sheet or film that has been rolled up with the tensile force applied to the end.
