ある。A conventional disk case is composed of a holder main body formed of a thermoplastic resin front and back sheet in a flat bag state as shown in Japanese Utility Model Laid-Open No. 2-56189, and a front and back non-woven fabric provided between the front and back sheets. Both the front and back non-woven fabrics are fixed to the front and back sheets at the fusion portion of the front and back sheets around the bag part of the holder body, that is, the front and back non-woven fabrics are interposed between the front and back sheets constituting the holder body, and both side edges Also, the front and back sheets are fused and integrated by interposing a non-woven fabric by heating and pressing at the lower edge portion.

縁固着は、表裏シート間に表裏の不織布を介在させた状
態で、上記表裏シート同士を不織布を介在した状態で融
着一体化するため、表裏シート同士の融着による接着力
が著しく弱くなる。Peripheral fixation other than the upper edge opening of the conventional disk case as described above, in the state of interposing the front and back non-woven fabric between the front and back sheets, in order to fuse together the front and back sheets with the non-woven fabric intervening, The adhesive strength due to the fusion of the front and back sheets is significantly weakened.
このため、ディスクや歌詞カードの収納に際し、ディス
クケースの表裏シートと不織布との両上縁を同時につか
んで互に相反する方向に引っ張りながら解放するので、
上記ディスクケースの両側縁上端の融着部分に上記解放
にともなう相反する方向への緊張力が作用し、上記緊張
力により短期間の内に裂け目が発生する問題があった。Therefore, when storing a disc or lyrics card, both upper and lower edges of the disc case and the non-woven fabric are grasped at the same time and released while pulling in mutually opposite directions,
There has been a problem that tension forces in opposite directions due to the release act on the fusion-bonded portions at the upper ends of both side edges of the disk case, and the tension force causes a tear in a short period of time.
そこで、この考案は融着部分に裂け目が発生しないよう
にしたディスクケースを提供することを目的とする。Therefore, an object of the present invention is to provide a disc case in which a tear is not generated in a fusion-bonded portion.
上記の目的を達成するために、この考案は軟質な合成樹
脂の表裏シートと、この表裏シート間に介在した表裏の
不織布とからなり、表裏シートの両側縁及び下縁を上記

にする許容部を設けて、この許容部により重なり合う上
記表裏シートの側縁を加熱加圧によって融着一体化して
構成したものである。In order to achieve the above object, the present invention comprises a soft synthetic resin front and back sheet and front and back non-woven fabric interposed between the front and back sheets. In a disk case that is fused and integrated by heating and pressing with a non-woven fabric interposed in the above, an allowance portion that allows the front and back sheets to overlap each other is provided at the upper end of both side edges of the front and back non-woven fabric, and the allowance portion causes the overlap. The side edges of the front and back sheets are fused and integrated by heating and pressing.
表裏シートの両側縁及び下縁を上記表裏シート間に表裏
の不織布を介在させた状態で加熱加圧により融着一体化
してディスクケースを製造する際、表裏の不織布の両側
上縁の許容部により表裏シートの裏面が互に重なり合っ
て、重なり合った裏面の融着により表裏シートの側縁が
不織布を介在しない状態で融着一体化される。When manufacturing the disk case by fusion-bonding both side edges and lower edges of the front and back sheets with heat and pressure while interposing the front and back nonwoven sheets between the front and back sheets, the allowances on both upper edges of the front and back nonwoven sheets are used. The back surfaces of the front and back sheets are overlapped with each other, and by fusion bonding of the overlapped back surfaces, the side edges of the front and back sheets are fused and integrated without interposing the nonwoven fabric.
その結果、ディスクケースの開口の解放にともない表裏
シートの側縁融着部分に強い緊張力が作用しても、許容
部により不織布の介在しない表裏シートの側縁同志の融
着部分により裂けるのを防止する。As a result, even if a strong tension is applied to the side edge fused portions of the front and back sheets due to the opening of the disc case opening, the permissible portion will not tear the side edge fused portions of the front and back sheets without the interposition of the nonwoven fabric. To prevent.
以下、この考案に係る実施例を添付図面に基づいて説明
する。Hereinafter, an embodiment according to the present invention will be described with reference to the accompanying drawings.
図において、１、１′は表裏シートである。In the figure, reference numerals 1 and 1'denominate front and back sheets.
上記の表裏シート１、１′には、ポリエチレン樹脂など
の軟質の熱可塑製合成樹脂シートが用いられる。For the front and back sheets 1 and 1 ', soft thermoplastic synthetic resin sheets such as polyethylene resin are used.
２、２′は上記表裏シート１、１′間に介在する表裏の
不織布である。Reference numerals 2 and 2 ′ are front and back non-woven fabrics interposed between the front and back sheets 1 and 1 ′.
上記の表裏の不織布２、２′には、ポリエチレンその他
の融点の低い熱可塑性樹脂を素材とする合成樹脂製が用
いられる。The front and back non-woven fabrics 2 and 2'are made of synthetic resin such as polyethylene or other thermoplastic resin having a low melting point.
次に上記表裏シート１、１′及び表裏の不織布２、２′
を用いたディスクケースの製法を説明する。Next, the front and back sheets 1, 1'and the front and back non-woven fabrics 2, 2 '
A method of manufacturing a disk case using the will be described.
まず、表裏シート１、１′間に表裏の不織布２、２′を
介在させて積層する。First, the front and back sheets 1 and 1'are laminated with the front and back nonwoven fabrics 2 and 2 'interposed therebetween.
次いで、表裏シート１、１′の両側縁及び下縁を上記表
裏シート１、１′間に表裏の不織布２、２′を介在させ
た状態で加熱加圧により融着４一体化してディスクケー
スＡを製造する。Then, the both sides and the lower edge of the front and back sheets 1, 1'are fused 4 by heat and pressure with the non-woven fabrics 2, 2'on both sides of the front and back sheets 1, 1'integrated to form a disc case A. To manufacture.
上記の加熱加圧にともない、不織布２、２′の両側縁上
端において、不織布２、２′を介在しないで表裏シート
１、１′の側縁同志の重なりを可能にする許容部３によ
り表裏シート１、１′の重なり合った側縁のみが融着４
される。Along with the above heating and pressurization, the front and back sheets are provided by the allowance portion 3 that allows the side edges of the front and back sheets 1, 1'to overlap each other at the upper ends of both side edges of the non-woven fabric 2, 2'without interposing the non-woven fabrics 2, 2 '. Only 1 and 1'overlapping side edges are fused 4
To be done.
なお、上記の許容部３としては、第４図に示すように表
裏シート１、１′の両側縁上端のコーナーをＬ形に切欠
いたが、第５図に示すように貫窓等がある。As the allowance portion 3, the corners at the upper ends of both side edges of the front and back sheets 1, 1 ′ are notched in an L shape as shown in FIG. 4, but there are through windows and the like as shown in FIG.
図中５は表裏シート１、１′と表裏の不織布２、２′片
方上縁を一体化する融着部である。In the figure, reference numeral 5 is a fused portion that integrates the front and back sheets 1, 1'and the front and back nonwoven fabrics 2, 2'one upper edge.
上記構成されたディスクケースＡの表裏の不織布２、
２′の間には、ディスクａが収納され、また、融着部５
のないシート１′と不織布２′との間には、歌詞カード
が収納される。Nonwoven fabrics 2 on the front and back of the disk case A configured as described above,
A disc a is housed between the 2'and the fused portion 5
A lyric card is accommodated between the non-woven sheet 1'and the non-woven fabric 2 '.
以上のように、この考案に係るディスクケースによれ
ば、許容部により表裏シートの両側縁上端同志を融着、
即ち他の融着部分のように表裏シート間に表裏の不織布
を介在させない状態で融着してあるので、融着部分の接
着強度が著しく強くなる。As described above, according to the disc case of the present invention, the allowances allow the upper and lower edges of the front and back sheets to be fused together.
That is, unlike other fused portions, since the non-woven fabrics on the front and back are not interposed between the front and back sheets, the adhesive strength of the fused portions is significantly increased.
このため、ディスクの収納にともないディスクケースの
開口を開いたとき、融着部分に強い緊張力が作用しても
上記融着部分が裂けるような不都合をなくすことができ
る。Therefore, when the opening of the disc case is opened for accommodating the disc, it is possible to eliminate the inconvenience that the fusion-bonded portion is torn even if a strong tension is applied to the fusion-bonded portion.
