Description
【０００１】[0001]
本考案はテープカセット、フロッピーディスク等の記録媒体用収納ケースに関 する。 The present invention relates to a storage case for recording media such as tape cassettes and floppy disks.
【０００２】[0002]
従来、磁気テープ等の記録媒体はその表面に塵埃が付いたり、表面を傷つけた りすると、記録が喪失し、誤記録、誤表示等を行うようになる。そこで、オーデ ィオ、ビデオ等のテープカセットやフロッピーディスク等では不使用時にプラス チック、紙等のケースに収納して保護している。 Conventionally, when a recording medium such as a magnetic tape is dusted or scratched on the surface thereof, the recording is lost and erroneous recording or erroneous display is performed. Therefore, when not in use, such as audio and video tape cassettes and floppy disks, they are stored in plastic or paper cases to protect them.
【０００３】 このような収納ケースとして、例えばプラスチック製のスリーブ型収納ケース を組み立てる場合、最初溶融状態のプラスチックをシリンダーで押し出し成形し 、大きな正方形状又は長方形状の平板シートを形成する。次に、原反たる平板シ ートのケースの外側となる面に印刷により意匠を施す。通常、その後の平板シー トに対する管理や加工は全て意匠面を上にして行う。何故なら、意匠面を下にす ると、印刷の乾きが悪かったりすると、印刷面が擦れる等して不具合が発生する からである。In the case of assembling a sleeve type storage case made of plastic, for example, as such a storage case, first, plastic in a molten state is extruded by a cylinder to form a large square or rectangular flat sheet. Next, a design is applied by printing on the outer surface of the case of the flat sheet which is the original warp. Normally, the subsequent control and processing of the flat sheet is done with the design side facing up. This is because if the design side is placed down and the printing quality is poor, the printing surface will rub and problems will occur.
【０００４】 そこで、意匠面を上にして打抜き刃及び筋押し刃を配設した金型の定盤上に載 せ、平板シートからブランクスを一度に多数枚打ち抜き、筋押しする。その際、 各ブランクスの外形が収納ケースを展開した図の輪郭線に沿って切断され、打ち 抜かれると同時に、筋押しを行って製凾に必要な折曲用の溝を形成する。その際 、ブランクスの筋押し箇所には図５に示すように上面に深い折曲用溝１０、下面 に浅い反動溝１２ができる。このブランクスを製凾機に投入し、折曲用溝１０が 収納ケースの外側にでるように矢印方向に折り曲げ（山折り）を行いながら、所 定箇所を重畳、溶着して収納ケースを組み立てる。Therefore, the blank is punched from a flat sheet at a time by a large number of blanks being punched at a time by placing them on a surface plate of a mold having a punching blade and a creasing blade with the design surface facing upward. At that time, the outer shape of each blank is cut along the contour line of the unfolded drawing of the storage case and punched, and at the same time, it is pressed to form a groove for bending which is necessary for manufacturing. At this time, a deep bending groove 10 is formed on the upper surface and a shallow reaction groove 12 is formed on the lower surface, as shown in FIG. The blanks are put into a scissor making machine, and while folding (mountain folding) in the direction of the arrow so that the bending groove 10 is located on the outside of the storage case, predetermined positions are overlapped and welded to assemble the storage case.
【０００５】[0005]
しかしながら、このような収納ケースは筋押し箇所の折り曲げに対する反発が 大きく、図６に示すように口部１４が変形し易く、口開き量ａが大きくなる。そ れ故、口部１４から塵埃が侵入し易く、記録媒体が落下し易い等の問題が発生す る。なお、１６（１６ａ、１６ｂ）は左右側面板、１８（１８ａ、１８ｂ）は上 底面板、２０は背面板である。 However, such a storage case has a large repulsion against bending of the muscle pushing portion, the mouth portion 14 is easily deformed as shown in FIG. 6, and the mouth opening amount a becomes large. Therefore, there are problems that dust easily enters from the mouth portion 14 and the recording medium easily drops. Reference numerals 16 (16a, 16b) are left and right side plates, 18 (18a, 18b) are upper and bottom plates, and 20 is a back plate.
【０００６】 本考案はこのような従来の問題点に着目してなされたものであり、口部の変形 の少ない記録媒体用収納ケースを提供することを目的とする。The present invention has been made in view of such conventional problems, and an object thereof is to provide a storage case for a recording medium in which the mouth portion is less deformed.
【０００７】[0007]
上記目的を達成するために、本考案による記録媒体用収納ケース５２には打ち 抜き加工と同時に筋押し線３６、３８、４０、４２、４４、５０を施したプラス チック製の平板シートのブランクス２２を用い、その筋押し線３６、３８、４０ 、４２、４４、５０を折り曲げ、組み立てを行う。しかも、平板シートとして、 筋押しの際に収納ケース５２の内側となる面を押して線３６、３８、４０、４２ 、４４、５０を施したものを用いる。 In order to achieve the above object, the storage case 52 for a recording medium according to the present invention is punched, and at the same time, ridged lines 36, 38, 40, 42, 44 and 50 are applied to the blank case 22 made of a plastic flat sheet. Is used to fold the muscle pushing lines 36, 38, 40, 42, 44 and 50 to assemble. Moreover, as the flat sheet, a sheet in which lines 36, 38, 40, 42, 44 and 50 are formed by pushing the inner surface of the storage case 52 at the time of pushing the line is used.
【０００８】 又、平板シートとして、成形時に収納ケース５２の外側となる面に意匠を施し たものを用いると好ましくなる。Further, it is preferable to use, as the flat sheet, a sheet having a design on the outer surface of the storage case 52 at the time of molding.
【０００９】[0009]
上記のように構成し、筋押しの際に、収納ケース５２の内側となる面を押して 線３６、３８、４０、４２、４４、５０を施すと、折曲用溝５０が収納ケースの 内側に入るため、筋押し箇所の折り曲げに対する反発が小さくなる。 With the above-described structure, when pushing the inner surface of the storage case 52 to make lines 36, 38, 40, 42, 44, and 50 when pushing a line, the bending groove 50 is placed inside the storage case. Since it enters, the repulsion against bending of the muscle pushing portion becomes small.
【００１０】 又、平板シートの成形時、収納ケース５２の外側となる面に意匠を施すと、平 板シートの成形工程で意匠を施せるため、印刷メーカーに輸送する等の必要もな く、収納ケースの組立てまで一貫工程を採用し易くなる。しかも、印刷品に発生 する不具合もない。In addition, when a flat sheet is formed, if a design is applied to the outer surface of the storage case 52, the design can be performed in the flat sheet forming step, and therefore, it is not necessary to transport it to a printing maker, and it is stored. It becomes easy to adopt an integrated process to assemble the case. Moreover, there are no problems with printed products.
【００１１】[0011]
以下、添付図面に基づいて、本考案の実施例を説明する。 図１は図２のＸ−Ｘ線拡大断面図、図２は本考案を適用したＶＨＳビデオテー プカセット用スリーブ型収納ケースの外側から見たブランクスを示す平面図であ る。図中、２２は平板シートからなるブランクス、２４はその上面板、２６は底 面板、２８は背面板、３０（３０ａ、３０ｂ）は左右表側面フラップ、３２（３ ２ａ、３２ｂ）は左右裏側面フラップ、３４（３４ａ、３４ｂ）は左右耳フラッ プである。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an enlarged cross-sectional view taken along line XX of FIG. 2, and FIG. 2 is a plan view showing blanks seen from the outside of a sleeve type storage case for a VHS video tape cassette to which the present invention is applied. In the figure, 22 is a blank made of a flat sheet, 24 is a top plate thereof, 26 is a bottom plate, 28 is a back plate, 30 (30a, 30b) are left and right front and side flaps, and 32 (32a, 32b) are left and right back sides. The flaps 34 (34a, 34b) are left and right ear flaps.
【００１２】 又、３６、３８（３８ａ、３８ｂ）は上面板２４と背面板２８、左右表側面フ ラップ３０との間の筋押し線（反動溝）、４０、４２（４２ａ、４２ｂ）は背面 板２８と底面板２６、左右耳フラップ３４との間の筋押し線（反動溝）、４４（ ４４ａ、４４ｂ）は底面板２６と左右裏側面フラップ３２との間の筋押し線（反 動溝）である。なお、上面板２４の縁の中央部に浅い指掛け用切り欠き４６を設 け、底面板２６の縁の中央部に深い指掛け用切り欠き４８を設ける。Further, 36, 38 (38a, 38b) are muscle pushing lines (reaction grooves) between the upper plate 24, the rear plate 28, and the left and right front side flaps 30, and 40, 42 (42a, 42b) are rear faces. The muscle pushing lines (reaction grooves) between the plate 28 and the bottom plate 26, the left and right ear flaps 34, 44 (44a, 44b) are muscle pushing lines (reaction grooves) between the bottom plate 26 and the left and right back side flaps 32. ). A shallow finger hooking notch 46 is provided at the center of the edge of the top plate 24, and a deep finger hooking notch 48 is provided at the center of the edge of the bottom plate 26.
【００１３】 このようなブランクス２２は原反の成形時に、一面に意匠やメーカー名等を施 した大きな平板シートから製作する。そこで、原反の成形時に、外周面に多数の ブランクスに相当する意匠やメーカー名等を彫り込んだシリンダ−を用い、他の ロールと溶融状態のプラスチック等の原材料を挟持して大きな平板シートを成形 すると同時に、その一面に意匠やメーカー名等を施す。このようにして、原反の 成形工程で意匠等を施すと、印刷工程を省略できる。因みに、原反用プラスチッ ク材としてポリプロピレン、ポリエステル、ポリカーボネイト、ポリ塩化ビニル 等を使用する。The blanks 22 as described above are manufactured from a large flat sheet having a design, a manufacturer's name, etc. on one surface when forming the original fabric. Therefore, when forming the original fabric, a large flat sheet is formed by sandwiching other rolls and other raw materials such as plastic in the molten state with a cylinder that engraves designs and manufacturer's names corresponding to many blanks on the outer peripheral surface. At the same time, the design and manufacturer's name are given on one side. In this way, if a design or the like is applied in the process of forming the original fabric, the printing process can be omitted. By the way, polypropylene, polyester, polycarbonate, polyvinyl chloride, etc. are used as the plastic material for the original fabric.
【００１４】 次に、意匠等を施した面を下にして多数のブランクスに相当する打抜き刃と筋 押し刃を配設した金型の定盤上に載せ、冷間プレス加工によって一度にブランク ス２２を多数枚取りする。その際、打抜き刃によって各ブランクスの外形が収納 ケースを展開した図の輪郭線に沿って切断され、打ち抜かれる。同時に、筋押し 刃によって各ブランクスに筋押しが施される。しかも、図１に示すように筋押し 線として筋押し刃の押した面、即ち収納ケースの内側となる面に深い折曲用溝５ ０が形成され、意匠等を施した面に浅い反動溝４４ａができる。Next, with the surface with the design or the like facing downward, the blanks are placed on a surface plate of a die in which punching blades and bruising blades corresponding to a large number of blanks are arranged, and cold pressing is performed at once. Take many 22 pieces. At that time, the punching blade cuts the outer shape of each blank along the contour line of the drawing in which the storage case is developed, and punches. At the same time, the blanking blades are used to push each blank. In addition, as shown in FIG. 1, a deep bending groove 50 is formed on the surface pressed by the muscle pressing blade as a muscle pressing line, that is, the surface that is the inside of the storage case, and the shallow reaction groove is formed on the designed surface. 44a is formed.
【００１５】 このブランクス２２を製凾機に投入し、折曲用溝５０が収納ケースの内側にな るように矢印方向に折り曲げ（谷折り）を行いながら対応するフラップ同士を適 宜重畳し、溶着して両側面板を形成する。すると、図３に示すようなＶＨＳビデ オテープカセット用収納ケース５２の組み立てが完成する。このようにして、折 曲用溝５０を収納ケースの内側に入れると、筋押し箇所の折り曲げに対する反発 が小さくなる。それ故、図４に示すように口部５４が変形し難くなり、口開き量 ｂが少なくなる。The blanks 22 are put into a scissor machine, and the flaps are appropriately overlapped while being bent (valley fold) in the arrow direction so that the bending groove 50 is inside the storage case. Weld to form side plates. Then, the assembly of the VHS video tape cassette storage case 52 as shown in FIG. 3 is completed. In this way, when the bending groove 50 is put inside the storage case, the repulsion against bending of the reinforced portion is reduced. Therefore, as shown in FIG. 4, the mouth portion 54 is less likely to be deformed, and the mouth opening amount b is reduced.
【００１６】 消費者に販売する場合、収納ケース５２にＶＨＳビデオテープカセットを収め 、フィルム包装等を施して提供する。購入者はフィルム包装を取り除き、収納ケ ース５２からカセットを引き抜いて使用するが、使用後には再び収納ケース５２ に納めて保存する。ここで、筋押し法として冷間加工を用いて形成した折曲用溝 を収納ケースの外側にだす場合と内側に入れる場合との常温における口開き量Ａ 、Ｂを対比して表１に示す。なお、初期とは収納ケースからフィルム包装を取り 除き、カセットを引き抜いた直後の口開き量であり、保存後とはカセットを引き 抜いたまま５日間置いた後の口開き量である。When sold to a consumer, the VHS video tape cassette is stored in a storage case 52, and the VHS video tape cassette is film-wrapped and provided. The purchaser removes the film packaging and pulls out the cassette from the storage case 52 for use, but after use, it is stored again in the storage case 52 for storage. Table 1 compares the opening amounts A and B at room temperature when the bending groove formed by using cold working as the muscle pushing method is placed outside and inside the storage case. . Note that the initial stage is the opening amount immediately after the film packaging is removed from the storage case and the cassette is pulled out, and the storage period is the opening amount after the cassette is pulled out and left for 5 days.

【００１７】[0017]
以上説明した本考案によれば、筋押しの際、収納ケースの内側となる平板シ ートの面を押して線を施すため、折曲用溝が収納ケースの内側に入って、折り曲 げに対する反発が小さくなり、口部が変形し難く、口開き量が少なくなる。それ 故、口部から塵埃が侵入し難く、記録媒体も落下し難い。しかも、折り曲げに対 する反発が小さいと、折り曲げ箇所に無理がかからず、破れ難くなるため、薄い 平板シートを使用し易くなる。 According to the present invention described above, when the muscle is pushed, the surface of the flat sheet that is the inside of the storage case is pressed to make a line, so that the bending groove enters the inside of the storage case and is not bent. Repulsion is reduced, the mouth is less likely to be deformed, and the mouth opening amount is reduced. Therefore, dust is unlikely to enter through the mouth and the recording medium is also unlikely to drop. In addition, if the repulsion against bending is small, the bent portion is not forced and it is difficult to tear, so that it is easy to use a thin flat sheet.
【００１８】 又、平板シートの成形時に、収納ケースの外側となる面に意匠を施すと、平板 シートの成形工程で意匠を施せるため、印刷メーカーに輸送する等の必要もなく 、一貫工程により口部の変形の少ない優れた製品を製造できる。Further, when a flat sheet is molded, if a design is applied to the outer surface of the storage case, the design can be performed in the flat sheet molding process, and therefore, there is no need to transport it to a printing maker. It is possible to manufacture an excellent product with less deformation of the part.
