【考案の詳細な説明】
本考案は、ジヤケツト内面に不織布等のクリー
ニングライナーを配した、フロツピーデイスク収
納用ジヤケツトに関し、デイスクとの摩擦抵抗が
小さく、ライナーのクリーニング効果が大で、か
つライナーの剥離がないジヤケツトを提供するも
のである。[Detailed description of the invention] The present invention relates to a jacket for storing floppy disks in which a cleaning liner made of non-woven fabric or the like is arranged on the inner surface of the jacket. This provides a jacket that does not peel off.
フロツピーデイスクジヤケツトの内面には、収
納されたデイスクのクリーニングと保護のため
に、不織布等のクリーニングライナーが積層配設
されており、このライナーは通常、ジヤケツトを
構成するシートに線状の融着部、あるいは点状の
融着部により部分的に融着されている。 A cleaning liner made of non-woven fabric or the like is laminated on the inner surface of the floppy disk jacket to clean and protect the stored disk, and this liner is usually a linear fusion liner formed on the sheet that makes up the jacket. It is partially fused by a bonded part or a dot-like fused part.
しかし、従来の線状の融着部により融着したも
のは、融着部間にある非融着ライナーが寸法変化
して、たるみを生じることがあり、デイスクとの
摩擦抵抗増大の原因となる。 However, with conventional linear welded parts, the non-fused liner between the welded parts may change dimensions and sag, causing increased frictional resistance with the disk. .
また従来の点状に融着したものは、個々の融着
点における接着強度が弱いためかなり密に融着点
を配列する必要があり、その結果ライナーが動き
にくくなつて、クリーニング効果や暖衝保護効果
が薄れる欠点がある。 In addition, with conventional dot-bonded products, the adhesive strength at each individual welding point is weak, so it is necessary to arrange the welding points quite densely.As a result, the liner becomes difficult to move, and the cleaning effect and warming The disadvantage is that the protective effect is weakened.
本考案は上記諸欠点を改良したフロツピーデイ
スクジヤケツトである。 The present invention is a floppy disk jacket that has improved the above-mentioned drawbacks.
以下図面に従つて本考案の実施例について説明
する。 Embodiments of the present invention will be described below with reference to the drawings.

リーニングライナーである。 Figure 1 is a developed plan view of the jacket of the present invention;
The figure is an enlarged view of a portion thereof, and 1 is a jacket sheet made of a PVC sheet or the like, and 2 is a cleaning liner made of a nonwoven fabric or the like.
上記シート１とライナー２とは、その積層部分

た熱融着部３，３，……により融着され、各々の
融着部３，３，……は、密に集合した融着点４，
４，……よりなつている。 The sheet 1 and the liner 2 are fused over almost the entire surface of the laminated portion by heat fused parts 3, 3, . . . formed at predetermined intervals, and each of the fused parts 3, 3, . ...is a densely gathered fusion point 4,
4. It's more familiar.
融着点４は、直径（または辺長）0.1〜１mmの
大きさとし、この融着点を0.5〜1.5mm程度の間隔
で２ケ以上、好ましくは４〜９個程度集合させ
て、熱融着部３を形成する。 The welding points 4 have a diameter (or side length) of 0.1 to 1 mm, and 2 or more, preferably 4 to 9, of these fusion points are gathered at intervals of about 0.5 to 1.5 mm, and heat fused. Form part 3.
熱融着部３の大きさは、直径（または辺長）で
1.5〜５mm程度が好ましく、また隣り合う熱融着
部間の中心距離ｌは15〜50mm、好ましくは20〜40
mm程度とする。 The size of the heat-fused part 3 is the diameter (or side length).
It is preferably about 1.5 to 5 mm, and the center distance l between adjacent heat-sealed parts is 15 to 50 mm, preferably 20 to 40 mm.
Approximately mm.
熱融着部３の配列は、規則的な格子状配置のほ
か、多少不規則な配置であつてもよい。 The arrangement of the heat-sealed parts 3 may be a regular lattice arrangement or a somewhat irregular arrangement.
また開口部周縁やシート１周縁等には、線状融
着等を施し補強することもできる。 Further, the periphery of the opening, the periphery of the sheet 1, etc. can be reinforced by applying linear fusion or the like.
本考案によれば、従来個々に分散して設けられ

イナーのクリーニング効果、保護暖衝効果を高め
ることができる。 According to the present invention, a plurality of welding points, which were conventionally provided separately, are gathered together in a thermally welded portion 3.
Therefore, even if the distance between the heat-sealed parts 3 is increased, an adhesive strength equal to or greater than that of the conventional liner can be obtained, and as a result, the cleaning effect and protective warming effect of the liner are enhanced without causing peeling of the liner. be able to.

熱融着部３によりライナー２のたるみを防止する
ので、デイスクとの摩擦抵抗が増大することがな
い。 Furthermore, in order to obtain the same effect as the present invention, it is possible to increase the area of the fusion points and widen the interval between them, but in that case, the sheet 1 may be deformed by heating during thermal fusion, or the heat There are disadvantages such as the fused portion being hardened by the molten resin. On the other hand, in the present invention, even if the area of the thermally fused portion 3 is increased, the individual fused points 4, 4, . Since the liner 2 is prevented from sagging by the heat-sealed portions 3 disposed at appropriate locations, the frictional resistance with the disk does not increase.
