Description

本考案は、ＣＤやＤＶＤといったディスク状記録媒体用の紙製ケースに係り、詳しくは、再生や焼却に適し、自然環境に配慮したディスク状記録媒体用の紙製ケースに関する。   The present invention relates to a paper case for a disk-shaped recording medium such as a CD or a DVD, and more particularly to a paper case for a disk-shaped recording medium that is suitable for reproduction and incineration and that takes into consideration the natural environment.

従来、ディスク状記録媒体用の紙製ケースでは、ディスク状記録媒体を保持するために、ディスク状記録媒体の中心孔に係合する合成樹脂製のディスク保持部材が台紙に取り付けられているものがあるが、この紙製ケースを再生紙として再利用する際には、ディスク保持部材を取り外さなくてはならないことから手間が掛かっていた。このため、ディスク状記録媒体の内縁部が載置される台紙の位置に、粘着材をリング状に取り付け、粘着材によりディスク状記録媒体を保持するようにしたものがあった（例えば、特許文献１参照。）。   Conventionally, in a paper case for a disk-shaped recording medium, a synthetic resin disk holding member that engages with the center hole of the disk-shaped recording medium is attached to the mount to hold the disk-shaped recording medium. However, when this paper case is reused as recycled paper, it takes time and effort because the disk holding member must be removed. For this reason, there is one in which an adhesive material is attached in a ring shape at the position of the mount on which the inner edge portion of the disk-shaped recording medium is placed, and the disk-shaped recording medium is held by the adhesive material (for example, Patent Documents) 1).

しかし、上述の紙製ケースでは、ディスク状記録媒体を紙製ケースから取り外した際には、粘着材が剥き出しになることから、粘着材が汚れて粘着力が低下しやすく、また、製造工程が増えることからコストが嵩むことがあった。さらに、ディスク状記録媒体の内縁部に粘着材が付着して、ディスク状記録媒体が取り扱いにくくなることもあった。   However, in the above-mentioned paper case, since the adhesive material is exposed when the disc-shaped recording medium is removed from the paper case, the adhesive material becomes dirty and the adhesive force tends to be reduced. The cost may increase due to the increase. Furthermore, the adhesive material adheres to the inner edge of the disk-shaped recording medium, and the disk-shaped recording medium may be difficult to handle.

そこで本考案は、コストを掛けることなく、紙製の部材のみでディスク状記録媒体を確実に保持できるようにし、再利用や焼却に適したディスク状記録媒体用の紙製ケースを提供することを目的としている。   Therefore, the present invention provides a paper case for a disk-shaped recording medium that can be reliably held only by a paper member without cost and is suitable for reuse and incineration. It is aimed.

上記の目的を達成するため本考案のディスク状記録媒体用の紙製ケースは、ディスク状記録媒体の外径より大きな形状の裏板紙、中板紙及び表板紙の三枚を、この順序で重ねて貼り合わせたディスク状記録媒体用の紙製ケースであって、前記裏板紙は、表面中央部にディスク状記録媒体の内縁部を載置する凸部を有し、ディスク状記録媒体の厚さに対応した厚さを有する前記中板紙は、ディスク状記録媒体の外径より大きな内径の中板円形状切抜部を有し、前記表板紙は、ディスク状記録媒体の外径より大きく、かつ、前記中板円形状切抜部の内径より小さな内径の表板円形状切抜部を有し、裏板紙、中板紙及び表板紙を重ねて貼り合わせた状態で、前記凸部に内縁部を載置したディスク状記録媒体が前記中板円形状切抜部及び前記表板円形状切抜部の内周側に収納可能に形成されるとともに、前記表板円形状切抜部の半周分以下の範囲には、表板円形状切抜部の内周側に突出してディスク状記録媒体の外縁部を保持する保持片が形成され、前記中板円形状切抜部及び前記表板円形状切抜部の前記保持片に対向する位置には、中板円形状切抜部及び表板円形状切抜部の外周側に連続してディスク状記録媒体の外縁部に指掛可能な形状の指掛用切抜部が形成され、前記中板円形状切抜部は、前記指掛用切抜部側の半周の内径に対して前記保持片側の半周の内径が大きく形成されていることを特徴としている。   In order to achieve the above object, a paper case for a disk-shaped recording medium according to the present invention is formed by stacking three sheets of a backing board, a middle board, and a front board having a shape larger than the outer diameter of the disk-shaped recording medium in this order. A paper case for a bonded disc-shaped recording medium, wherein the back paperboard has a convex portion for placing the inner edge of the disc-shaped recording medium at the center of the surface, and has a thickness of the disc-shaped recording medium. The intermediate paperboard having a corresponding thickness has a middle circular cutout portion with an inner diameter larger than the outer diameter of the disc-shaped recording medium, and the front board is larger than the outer diameter of the disc-shaped recording medium, and A disc having a front plate circular cutout portion having an inner diameter smaller than the inner diameter of the middle plate circular cutout portion, and an inner edge portion placed on the convex portion in a state where the backboard paper, the middle paperboard and the front paperboard are laminated and bonded together Recording medium is the middle plate circular cutout portion and the front plate circular shape The outer peripheral edge of the disc-shaped recording medium is formed so as to be storable on the inner peripheral side of the cutout portion, and protrudes to the inner peripheral side of the front cutout circular cutout portion in a range equal to or less than a half circumference of the front cutout circular cutout portion. A holding piece for holding the portion is formed, and the middle plate circular cutout portion and the front plate circular cutout portion are arranged at positions facing the holding pieces of the middle plate circular cutout portion and the front plate circular cutout portion. A finger-hanging cutout shape is formed on the outer edge of the disc-shaped recording medium continuously on the outer peripheral side, and the middle plate-shaped cutout portion has an inner diameter of a half circumference on the finger-hanging cutout side. On the other hand, the inner diameter of the half circumference on the holding piece side is formed large.

本考案は上述のように、紙製の部材のみで紙製ケースを形成することにより、再生紙とする際には、簡単に水処理することができ、また、焼却する際にも有害物質を発生させることなく簡単に処理できる。さらに、保持片によりディスク状記録媒体を確実に保持することができると共に、指掛用切抜部に指をかけて、ディスク状記録媒体を簡単に紙製ケースから取り出すことができる。また、裏板紙に、ディスク状記録媒体の内縁部を載置する凸部を形成したことにより、ディスク状記録媒体の記録面と裏板紙とが接触することがなく、記録面が裏板紙によって傷つけられる虞がない。さらに、中板円形状切抜部は、指掛用切抜部側の半周の内径に対して保持片側の半周の内径が大きく形成されていることから、ディスク状記録媒体を紙製ケースに出し入れしやすい。   As described above, the present invention forms a paper case with only a paper member, so that it can be easily treated with water when used as recycled paper. It can be processed easily without generating. Further, the disc-shaped recording medium can be securely held by the holding piece, and the disc-shaped recording medium can be easily taken out from the paper case by placing a finger on the finger-hanging cutout portion. In addition, by forming a convex portion on the backboard to place the inner edge of the disk-shaped recording medium, the recording surface of the disk-shaped recording medium does not come into contact with the backboard, and the recording surface is damaged by the backboard. There is no fear of being. Furthermore, since the inner plate circular cutout portion is formed so that the inner diameter of the half circumference on the holding piece side is larger than the inner diameter of the half circumference on the finger catch cutout portion side, it is easy to take in and out the disc-shaped recording medium into and out of the paper case. .
