Description

本発明は、記録円盤プロテクターに関する。   The present invention relates to a recording disk protector.

従来、記録円盤（例えばＣＤＲ）の記録面を保護するために、記録円盤プロテクターを記録面に貼付させて、収納・保管している（例えば、特許文献１参照）。   Conventionally, in order to protect the recording surface of a recording disk (for example, CDR), a recording disk protector is attached to the recording surface and stored and stored (for example, see Patent Document 1).

しかし、記録円盤プロテクターと記録円盤の記録面は、相互に全面的に接触していた。そして、記録円盤プロテクターの粘着剤層からガスが発生することがあり、このガスが、記録円盤プロテクターと記録円盤の間に密封状となり、記録円盤の記録面に損傷を与える虞れがあった。
特開平９−１４７４１８号公報 However, the recording surface of the recording disk protector and the recording disk were in full contact with each other. Gas may be generated from the pressure-sensitive adhesive layer of the recording disk protector, and this gas is sealed between the recording disk protector and the recording disk, which may damage the recording surface of the recording disk.
JP-A-9-147418

解決しようとする課題は、ガスを外部に逃がすことができない点である。   The problem to be solved is that the gas cannot escape to the outside.

そこで、本発明に係る記録円盤プロテクターは、中心孔を有するドーナツ型基本シートの下面に、記録円盤の記録面に粘着分離自在に粘着される粘着剤層を備え、上記中心孔の直径を、記録円盤の中心孔の直径と同一寸法に設定し、３本以上のガス抜きスリットを径方向に貫設したものである。   Therefore, the recording disk protector according to the present invention includes an adhesive layer that is adhered to the recording surface of the recording disk in an adhesively separable manner on the lower surface of the donut-shaped basic sheet having the central hole, and records the diameter of the central hole. The diameter is the same as the diameter of the center hole of the disk, and three or more venting slits are provided in the radial direction.

また、粘着剤層が、多数の独立小突出子を有し、該独立小突出子間に、ガスを外部へ逃がすための溝を形成したものである。また、基本シートが紙から成るものである。また、ガス抜きスリットの近傍に、記録円盤の記録済みの量及び／又は記録用残量を表示する目盛部を有するものである。   The pressure-sensitive adhesive layer has a large number of independent small protrusions, and grooves for allowing gas to escape to the outside are formed between the independent small protrusions. The basic sheet is made of paper. Further, a scale portion for displaying the recorded amount of the recording disk and / or the remaining amount for recording is provided in the vicinity of the gas vent slit.

本発明の記録円盤プロテクターによれば、ガスを確実に外部に放出して、記録円盤の記録面を保護することができる。記録円盤に対して高精度に中心を一致させて（センタリングして）貼着することが容易である。   According to the recording disk protector of the present invention, the recording surface of the recording disk can be protected by reliably releasing the gas to the outside. It is easy to attach the center of the recording disk with high precision (centering).

図１・図２は、本発明の第１の実施の形態の使用状態を示す。すなわち、この記録円盤プロテクターＰは、記録円盤Ｅ（例えばＣＤＲ）の記録面Ｒに粘着分離自在に粘着されて、記録面Ｒに埃が付着したり傷が付いたりするのを防止する（すなわち、記録面Ｒを保護する）。   1 and 2 show a use state of the first embodiment of the present invention. That is, the recording disk protector P is adhered to the recording surface R of the recording disk E (for example, CDR) in an adhesively separable manner to prevent the recording surface R from being attached with dust or scratched (that is, The recording surface R is protected).

具体的には、中心孔１を有するドーナツ型基本シート２の下面２ａに、記録円盤Ｅの記録面Ｒに粘着分離自在に粘着される粘着剤層３を備える。基本シート２は天然紙から成る。粘着剤層３は、樹脂（例えば、ウレタン系粘着剤）から成る。   Specifically, an adhesive layer 3 is provided on the lower surface 2a of the donut-shaped basic sheet 2 having the center hole 1 and is adhered to the recording surface R of the recording disk E so as to be adhesively separable. The basic sheet 2 is made of natural paper. The pressure-sensitive adhesive layer 3 is made of a resin (for example, urethane-based pressure-sensitive adhesive).

径方向に３本以上のガス抜きスリット４が貫設されている。ガス抜きスリット４が１本又は２本の場合、十分なガス抜きができない虞れがある。ガス抜きスリット４の近傍に、記録円盤Ｅの記録済みの量、又は、記録用残量を表示する目盛部５を有する。５ａは記録済みの量を表示する目盛部を示し、５ｂは記録用残量を表示する目盛部を示す。
目盛部５は、オフセット印刷によって形成されている。オフセット印刷によって、容易に印刷することができる。 Three or more gas vent slits 4 are provided in the radial direction. When there are one or two gas vent slits 4, there is a possibility that sufficient gas venting cannot be performed. In the vicinity of the gas vent slit 4, there is a scale portion 5 for displaying the recorded amount of the recording disk E or the remaining amount for recording. 5a indicates a scale portion for displaying the recorded amount, and 5b indicates a scale portion for displaying the remaining amount for recording.
The scale part 5 is formed by offset printing. Printing can be easily performed by offset printing.

Ｋ1 は記録済部を示し、Ｋ2 は未記録部を示す。一般に、記録済部Ｋ1 は光を散乱し、未記録部Ｋ2 は光を鏡状に反射するので、両者は異なる色に見える。そして、記録済部Ｋ1 と未記録部Ｋ2 の境界線Ｌの位置にある目盛部５を読むことで、記録済みの量又は記録用残量（すなわち、それぞれの記憶容量、再生時間等）を知ることができる。 K 1 indicates a recorded part, and K 2 indicates an unrecorded part. Generally, the recorded portion K 1 scatters light, and the unrecorded portion K 2 reflects light in a mirror shape, so that they appear to be different colors. Then, by reading the scale portion 5 at the position of the boundary line L between the recorded portion K 1 and the unrecorded portion K 2 , the recorded amount or the remaining recording amount (that is, the respective storage capacity, reproduction time, etc.) Can know.

中心孔１の直径Ｄ1 は、記録円盤Ｅの中心孔Ｔの直径Ｄ2 と同一寸法に設定されている。直径Ｄ1 と直径Ｄ2 が異なる場合、記録円盤Ｅと記録円盤プロテクターＰを正確に位置合わせするのが困難であり、目盛部５が不適切な位置に配設されて、正確に記録済みの量や記録用残量を知ることができない虞れがある。 The diameter D 1 of the center hole 1 is set to the same dimension as the diameter D 2 of the center hole T of the recording disk E. When the diameter D 1 and the diameter D 2 are different, it is difficult to accurately position the recording disk E and the recording disk protector P, and the scale portion 5 is disposed at an inappropriate position so that the recording is correctly performed. There is a possibility that the amount and the remaining amount for recording cannot be known.

図３に示すように、粘着剤層３は、多数の略直方体状の独立小突出子６を有する。独立小突出子６間に、ガスを外部へ逃がすための格子状の溝７が形成されている。粘着剤層３でガスが発生した場合、ガスは、矢印Ｘに示すように、溝７から外部へ逃げることができる。また、矢印Ｙに示すように、中心孔１から外部へ逃げることができる。また、矢印Ｚに示すように、基本シート２を通り抜けて外部へ逃げることができる。   As shown in FIG. 3, the pressure-sensitive adhesive layer 3 has a large number of independent small protrusions 6 having a substantially rectangular parallelepiped shape. Between the independent small protrusions 6, lattice-like grooves 7 for allowing gas to escape to the outside are formed. When gas is generated in the pressure-sensitive adhesive layer 3, the gas can escape to the outside from the groove 7 as indicated by an arrow X. Further, as indicated by an arrow Y, the center hole 1 can escape to the outside. Further, as shown by an arrow Z, it can escape through the basic sheet 2 to the outside.

図４は、第２の実施の形態を示す。粘着剤層３の下面３ａに、剥離紙８が積層されている。この記録円盤プロテクターＰは、剥離紙８を剥離させて、粘着剤層３を記録円盤Ｅ（図２参照）の記録面Ｒに粘着させて使用する。   FIG. 4 shows a second embodiment. A release paper 8 is laminated on the lower surface 3 a of the pressure-sensitive adhesive layer 3. The recording disk protector P is used by peeling the release paper 8 and sticking the adhesive layer 3 to the recording surface R of the recording disk E (see FIG. 2).

図５及び図６は、第３の実施の形態を示す。すなわち、独立小突出子６は、同一所定高さ寸法Ｈで底面視形状がランダム（不均一）な柱状に形成されている。なお、図６は、剥離紙８を剥離した状態の底面図を示す。   5 and 6 show a third embodiment. That is, the independent small protrusions 6 are formed in a columnar shape having the same predetermined height dimension H and a random (non-uniform) bottom view shape. 6 shows a bottom view of the state in which the release paper 8 has been peeled off.

本発明は、設計変更可能であって、例えば、ガス抜きスリット４の近傍に、記録円盤Ｅの記録済みの量、及び、記録用残量を表示する目盛部５を有するも良い。また、基本シート２が合成紙から成るも良い。また、基本シート２にオフセット印刷にて、目盛部５以外に文字や絵等を印刷するも良い。また、基本シート２が上面２ｂ（図２参照）にコーティング層を有するも良い。   The present invention can be changed in design. For example, in the vicinity of the gas vent slit 4, there may be a scale portion 5 that displays the recorded amount of the recording disk E and the remaining amount for recording. The basic sheet 2 may be made of synthetic paper. Further, characters, pictures, etc. may be printed on the basic sheet 2 in addition to the scale portion 5 by offset printing. The basic sheet 2 may have a coating layer on the upper surface 2b (see FIG. 2).

以上のように、本発明は、中心孔１を有するドーナツ型基本シート２の下面２ａに、記録円盤Ｅの記録面Ｒに粘着分離自在に粘着される粘着剤層３を備え、中心孔１の直径Ｄ1 を、記録円盤Ｅの中心孔Ｔの直径Ｄ2 と同一寸法に設定し、３本以上のガス抜きスリット４を径方向に貫設したので、ガスを確実に外部に放出して、記録円盤Ｅの記録面Ｒを保護することができる。また、中心孔１を記録円盤Ｅの中心孔Ｔと位置合わせする（センターを合致させる）ことにより、容易に記録円盤Ｅの適切な位置に粘着させることができる。 As described above, the present invention includes the pressure-sensitive adhesive layer 3 that is adhered to the recording surface R of the recording disk E so as to be separable and separable on the lower surface 2 a of the donut-shaped basic sheet 2 having the central hole 1. The diameter D 1 is set to the same size as the diameter D 2 of the center hole T of the recording disk E, and three or more gas vent slits 4 are provided in the radial direction so that the gas is surely discharged to the outside. The recording surface R of the recording disk E can be protected. Further, by aligning the center hole 1 with the center hole T of the recording disk E (matching the center), the center hole 1 can be easily adhered to an appropriate position of the recording disk E.

また、粘着剤層３が、多数の独立小突出子６を有し、独立小突出子６間に、ガスを外部へ逃がすための溝７を形成したので、ガスをより確実に外部に放出して、記録円盤Ｅの記録面Ｒを保護することができる。
また、基本シート２が紙から成るので、基本シート２からもガスを逃がすことができて一層確実に記録円盤Ｅの記録面Ｒを保護することができる。また、安価にて大量生産することができる。
また、ガス抜きスリット４の近傍に、記録円盤Ｅの記録済みの量及び／又は記録用残量を表示する目盛部５を有するので、記録円盤Ｅの記録済みの量及び／又は記録用残量を知ることができる。特に、中心孔１の直径Ｄ1 を、記録円盤Ｅの中心孔Ｔの直径Ｄ2 と同一寸法に設定したので、記録円盤Ｅに位置合わせする（センターを合致させる）のが容易であって、正確な記録済みの量及び／又は記録用残量を知ることができる。 Moreover, since the adhesive layer 3 has a large number of independent small protrusions 6 and the grooves 7 are formed between the independent small protrusions 6 for allowing the gas to escape to the outside, the gas is more reliably discharged to the outside. Thus, the recording surface R of the recording disk E can be protected.
Further, since the basic sheet 2 is made of paper, gas can be released from the basic sheet 2 and the recording surface R of the recording disk E can be more reliably protected. Further, it can be mass-produced at a low cost.
Further, since the scale portion 5 for displaying the recorded amount and / or the remaining recording amount of the recording disk E is provided in the vicinity of the gas vent slit 4, the recorded amount and / or the remaining recording amount of the recording disk E is displayed. Can know. In particular, the diameter D 1 of the center hole 1, since the set diameter D 2 of the same size of the central hole T of the recording disk E, there is easy to align the recording disk E (match the center), An accurate recorded amount and / or remaining amount for recording can be known.
