Description

この発明は、見開き状クリアポケットファイル及びその製造方法に関し、特に、たとえば、クリヤーブックなどの背表紙部の両側に表表紙部と裏表紙部が連設され、大きめサイズの書類などを見開いて見ることができるように表表紙側と裏表紙側との間に跨って収納できる、透明ポケットが固着されたファイル及びその製造方法に関する。 The present invention relates to a spread-out clear pocket file and a manufacturing method thereof, and in particular, for example, a front cover portion and a back cover portion are continuously provided on both sides of a back cover portion of a clear book or the like, and a large size document or the like is opened and viewed. The present invention relates to a file to which a transparent pocket is fixed and a method for manufacturing the same that can be stored between the front cover side and the back cover side.

従来、透明のファイルムでポケットを形成した透明ポケットファイルがある。
それには、ポケットが表紙に溶着固定されたファイルにおいてポケットが見開いた状態でつくられ、それを数枚重ねたものの中央部を、溶解して表紙の背部に溶着又は綴じ具に綴じることにより、ポケットを綴じたファイルがある（特許文献１及び２参照）。 Conventionally, there is a transparent pocket file in which a pocket is formed by a transparent file.
To do this, the pockets are created with the pockets open in a file with the pockets welded and fixed to the cover. (See Patent Documents 1 and 2).

特許文献１のファイルでは、そして、ポケット１枚１枚をそれぞれ表紙に融着したものであっても、ポケット枚数が増えるに従い、見開いた時、ポケットの厚み、書類の厚みにより見開きが中央にゆくに従ってフラットからどんどんカーブしていき、結果的に見開きが悪くなってしまう。
表表紙部側と裏表紙部側との間に跨って挟み込まれた書類などに、本来の折り目と異なる折り目がついてしまう。
また、特許文献２のファイルでは、ポケット１枚１枚が分割されていることにより、各ポケットが動いて特許文献１と同様の問題がある。 In the file of Patent Document 1, even if each pocket is fused to the cover, as the number of pockets increases, the spread spreads to the center due to the thickness of the pocket and the thickness of the document. As you follow, the curve gradually increases from flat, resulting in poor spread.
A crease different from the original crease is attached to a document sandwiched between the front cover part side and the back cover part side.
Moreover, in the file of patent document 2, since each pocket is divided | segmented, each pocket moves and there exists a problem similar to patent document 1. FIG.

前記の製本装置１０００を使用してファイルを製本する方法について説明する。
まず、図１０に示すように、多数枚のシート状ポケット２２を重合し、その重なり端面を固定のシート状ポケット押圧部１００８と可動シート状ポケット押圧部１０１２とでクランプし、且つ、表紙体用保持機構１００４により、表紙体１８の内面を下側にした状態で、表紙体１８を保持し、表紙体用保持機構１００４を下降させてシート状ポケット群２０の溶着縁３２の上面と表紙体１８の内面とを対向させるとともに、その間に発熱体１００６（Ｈ）を介在させることができる位置まで接近させる。
そして、発熱体１００６（Ｈ）を両者の間に介在させ、表紙体１８の内面と第１ポケット構成シート３０の溶着縁３２の上部のつき合せ端縁とを同時に溶融させる。 A method of binding a file using the bookbinding apparatus 1000 will be described.
First, as shown in FIG. 10, a large number of sheet-like pockets 22 are superposed, the overlapping end surfaces thereof are clamped by a fixed sheet-like pocket pressing part 1008 and a movable sheet-like pocket pressing part 1012, and for the cover body With the holding mechanism 1004, the cover body 18 is held with the inner surface of the cover body 18 facing down, the cover body holding mechanism 1004 is lowered, and the upper surface of the welding edge 32 of the sheet-like pocket group 20 and the cover sheet 18. The inner surface of the heating element 1006 is made to face the heating element 1006 (H) between them.
Then, the heating element 1006 (H) is interposed between them, and the inner surface of the cover body 18 and the butt edge at the upper part of the welding edge 32 of the first pocket forming sheet 30 are melted simultaneously.

その溶融温度は、ポリプロピレンの溶融温度が、１２０〜１３０℃であるため、１７０〜１８０℃前後の発熱体１００６を使用して４〜５秒前後の時間で、表紙体１８の内面と第１ポケット構成シート３０の溶着縁３２の上縁のつき合せ端縁とを同時に溶融させる。
その後、表紙体１８と溶着縁３２との間から発熱体１００６（Ｈ）を引き抜き、背表紙部１６を第１ポケット構成シート３０の溶着縁３２に接触させて両者を接合する（図１２参照）。 Since the melting temperature of polypropylene is 120 to 130 ° C., the inner surface of the cover body 18 and the first pocket are used in about 4 to 5 seconds using a heating element 1006 of about 170 to 180 ° C. The joining edge of the upper edge of the welding edge 32 of the component sheet 30 is simultaneously melted.
Thereafter, the heating element 1006 (H) is pulled out from between the cover sheet 18 and the welding edge 32, and the spine cover 16 is brought into contact with the welding edge 32 of the first pocket forming sheet 30 to join them together (see FIG. 12). .

そして、適宜、溶着部位を冷却して、完全に表紙体１８の背表紙部１６の内面と第１ポケット構成シート３０の溶着縁３２のつき合せ端縁とを固着する。 Then, the welding portion is appropriately cooled, and the inner surface of the spine cover portion 16 of the cover body 18 and the abutting edge of the welding edge 32 of the first pocket constituting sheet 30 are completely fixed.

実際の使用においては、第１ポケット構成シート３０と第２ポケット構成シート４０との間に形成された収容部８０に収容される被挟体Ｓを、第２ポケット構成シート４０の開口縁４２及び第３ポケット構成シート５０の開口縁５２より第２ポケット構成シート４０の収容部８０及び第３ポケット構成シート５０の収容部８２に挿入し、被挟体ＳをＡ面側シート状ポケット２２の収容部８０とＢ面側のシート状ポケット２２の収容部８２に跨って収容する。
而して、表表紙部１２と裏表紙部１４とを開き、見開いた状態で、シート状ポケット２２の収容部８０及び収容部８２に挿入された被挟体Ｓを閲覧できる。
そして、表表紙部１２と裏表紙部１４を閉じたときは、被挟体Ｓの幅方向における中央領域を、隣接するＡ面側のシート状ポケット２２とＢ面側のシート状ポケット２２との中間に位置させ、被挟体Ｓの折り曲げ部Ｓ₁が隣接するＡ面側のシート状ポケット２２とＢ面側のシート状ポケット２２との中間において高さ方向に第１ポケット構成シート３０の溶着縁３２に沿ってのび、見開いた状態でシート状ポケット２２の収容部８０及び収容部８２に挿入されるように構成されているので、被挟体Ｓの中央に正確に折り目を形成できる。 In actual use, the sandwiched body S accommodated in the accommodating portion 80 formed between the first pocket constituting sheet 30 and the second pocket constituting sheet 40 is used as the opening edge 42 of the second pocket constituting sheet 40 and Inserted into the accommodating portion 80 of the second pocket constituting sheet 40 and the accommodating portion 82 of the third pocket constituting sheet 50 through the opening edge 52 of the third pocket constituting sheet 50, and the sandwiched body S is accommodated in the A-side sheet-like pocket 22 It accommodates across the part 80 and the accommodating part 82 of the sheet-like pocket 22 on the B surface side.
Thus, the front cover portion 12 and the back cover portion 14 are opened, and the sandwiched body S inserted into the storage portion 80 and the storage portion 82 of the sheet-like pocket 22 can be browsed in a state of being opened.
When the front cover portion 12 and the back cover portion 14 are closed, the central region in the width direction of the sandwiched body S is defined by the adjacent sheet-like pocket 22 on the A-side and the sheet-like pocket 22 on the B-side.
