Description

本発明は、記載された内容の秘密保持を可能とした隠蔽葉書に関し、特に、郵送された葉書が受取人に渡る前に、その葉書に記入された情報が第三者に盗み見られることを防止するとともに、受取人が、開封しやすい隠蔽葉書に関するものである。   The present invention relates to a concealed postcard that enables confidentiality of the contents described, and in particular, prevents the information entered in the postcard from being stolen by a third party before the postcard sent to the recipient is delivered to the recipient. In addition, it relates to a cover-up postcard that is easy for the recipient to open.

従来、郵送された葉書に記載された内容が、受取人に渡る前の段階で、第三者に盗み見られないように工夫された隠蔽葉書が種々開発され、既に使用されている。これらの隠蔽葉書については、例えば、葉書サイズの略２倍の折畳み用紙を用いて折り用ミシン目を介し、隠蔽片（上片）、情報を記入する葉書本体片（下片）からなる二折葉書において、葉書本体片に隠蔽用紙片を接着し隠蔽状態にされた葉書を受取人が、その葉書を受け取った後に、見開きできるように隠蔽片との間に透視できしかも層間が剥離可能に重合された接合材の両側に透明な粘着剤を有する透明シートなどを設けた情報隠蔽葉書作成用紙片が知られている（例えば、特許文献１参照）。また、透明性基材の片面に、粘着剤層を介して剥離シートを設け、該透明性基材の他の片面は、不透明性基材上に剥離可能に接着されている隠蔽ラベル構造を有する申込帳票が提案されている（例えば特許文献２参照）。さらには、折り用ミシン線を介して情報記入用紙片と情報隠蔽用紙片とが連接され、情報隠蔽用紙片上に、接着剤層と、上面に透明な粘着剤層及び下面に剥離剤層を有する透明シートと、剥離紙とが順次重ねられてなる葉書作成用紙であって、透明性シートの下面の一部と、情報隠蔽用紙片の上面の一部とを直接接着する接着剤層が設けられている葉書を本出題人は、特願２００４−２１６７１８号にて提案している。   Conventionally, various concealed postcards that have been devised so that the contents described in the mailed postcards cannot be stolen by a third party before being delivered to the recipient have been developed and used. As for these concealment postcards, for example, two folds comprising a concealment piece (upper piece) and a postcard body piece (lower piece) for entering information through a folding perforation using a folding sheet approximately twice the size of the postcard size. In the postcard, the concealment paper piece is adhered to the postcard body piece and the concealed postcard is superposed so that the recipient can see through the concealment piece so that it can be opened after receiving the postcard, and the layers can be peeled off. There is known an information concealment postcard creation paper piece provided with a transparent sheet having a transparent adhesive on both sides of the bonded material (see, for example, Patent Document 1). In addition, a release sheet is provided on one side of the transparent substrate via an adhesive layer, and the other side of the transparent substrate has a concealing label structure that is releasably bonded onto the opaque substrate. An application form has been proposed (see, for example, Patent Document 2). Furthermore, the information entry sheet piece and the information hiding paper piece are connected via a folding sewing line, and the adhesive layer, the transparent adhesive layer on the upper surface, and the release agent layer on the lower surface are provided on the information hiding paper piece. A postcard-preparing sheet in which a transparent sheet and release paper are sequentially stacked, and an adhesive layer is provided to directly bond a part of the lower surface of the transparent sheet and a part of the upper surface of the information hiding sheet piece. This post has been proposed in Japanese Patent Application No. 2004-216718.

しかしながら、上記の特許文献１に開示された隠蔽葉書は、隠蔽片がダブルタック方式であり、剥離可能に重合した接合材の両側に透明な粘着剤層を有する非常に複雑な多層構造となっており、コストが高くつくという問題がある。上記特許文献２に開示された隠蔽ラベルは、シンプルな構造となり、低コスト化されたが、記入情報を隠蔽状態にするために、剥離シートを剥離する際に、剥離シートと共に透明基材まで一緒に剥離させてしまう不手際を生じることがある。また、郵送された隠蔽葉書を受取人が、開封に際し、隠蔽用紙片と透明基材との界面で剥離ができず、隠蔽用紙片が破れる場合がある。本出題人が、特願２００４−２１６７１８号にて提案した葉書作成用紙は、低コストで、しかも、記入情報を隠蔽状態にするために、剥離シートを剥離する際に、剥離シートと共に透明基材まで一緒に剥離させてしまうという問題は解消されているが、郵送された隠蔽葉書を受取人が、開封するときに、隠蔽用紙片と透明基材との界面で剥離ができず、隠蔽用紙片が破れる場合があるという問題点がある。   However, the concealment postcard disclosed in the above-mentioned Patent Document 1 has a very complicated multilayer structure in which the concealment piece is a double-tack type and has a transparent adhesive layer on both sides of the joining material polymerized in a peelable manner. There is a problem that the cost is high. The concealment label disclosed in Patent Document 2 has a simple structure and has been reduced in cost. However, in order to conceal the written information, when the release sheet is peeled off, the release sheet and the transparent base material are combined together. It may cause trouble to peel off. In addition, when the recipient opens the concealed postcard that has been mailed, the concealment piece may not be peeled off at the interface between the concealment piece and the transparent substrate. The postcard preparation paper proposed by the present examiner in Japanese Patent Application No. 2004-216718 is low in cost, and when the release sheet is peeled off in order to conceal the entry information, a transparent base material is used together with the release sheet. However, when the recipient opens the concealed postcard that has been mailed, it cannot be peeled off at the interface between the concealed paper piece and the transparent substrate, and the concealed paper piece There is a problem that may be torn.

前記隠蔽用紙片の破れについて鋭意、原因追求の結果、次のことが判明した。隠蔽葉書は、一般的には、汎用のフォーム輪転印刷機でオフセット印刷が施されている。多色印刷を行う場合には、複数の印刷ユニットを有する多色印刷機が用いられ、隠蔽用紙片の剥離剤層も印刷により形成される。ここで、印刷について説明する。オフセット印刷機の印刷ユニットには、版胴（印刷胴）及びブランケット胴（転写胴）がそれぞれ設けられている。版胴には、印刷される絵柄（画線）を焼き付けた刷版が取付けられており、インク供給装置によりインクが版胴に供給されると、この刷版上の絵柄がブランケット胴に一旦転写され、その後、ブランケット胴に転写された絵柄が走行する基紙ウェブに印刷される。また、刷版は、例えばアルミニウムにより形成された板状の部材であって、版胴に取り付けられている。さらに、刷版の装着作業について簡単に説明すると、刷版の装着時には、刷版の一端側（くわえ側）を版胴に形成されたギャップの一端部に係合させて、刷版を版胴に巻き付ける。そして、刷版の他端側（くわえ尻側）を上記ギャップに押し込み、この他端部をクランプ装置で固定する。これにより、刷版が版胴に巻き着けられた状態で固定されるのである。また、版胴と同様に、ブランケット胴の外周面にも絵柄が転写されるゴム版が設けられており、版胴のギャップと同様なギャップが形成されている。このように通常のオフセット印刷機では、上述したようなギャップが存在するため、このギャップの部分には絵柄を形成することができない。このために隠蔽用紙片の剥離剤層のように、ギャップ部にも剥離剤層を設け、隠蔽用紙片の天地方向に連続して剥離剤層が必要な場合には、別の印刷ユニットを使用して見当を合わせてギャップ部に剥離剤層を印刷して、連続した剥離剤層が設けられている。しかし、剥離剤層の印刷見当ズレが発生した場合、隠蔽用紙片の一部に剥離剤層が存在しない部分が発生する。特に、剥離剤層が存在しない部分が隠蔽用紙片の剥離開始位置に一致した場合、隠蔽葉書の受取人が隠蔽用紙片を開封しようとした場合に、剥離剤層のない部分が透明基材と強接着された状態となり、隠蔽用紙片の破れ発生が起きる。
特開平１０−２６４５５９号公報 特開２００４−９７２０号公報 As a result of earnest and pursuit of the cause of the tearing of the cover sheet, the following has been found. The concealed postcard is generally subjected to offset printing by a general-purpose form rotary printing press. In the case of performing multicolor printing, a multicolor printing machine having a plurality of printing units is used, and the release agent layer of the concealment paper piece is also formed by printing. Here, printing will be described. The printing unit of the offset printing machine is provided with a plate cylinder (printing cylinder) and a blanket cylinder (transfer cylinder). The plate cylinder is attached with a printing plate on which a pattern to be printed (image line) is baked. When ink is supplied to the plate cylinder by an ink supply device, the pattern on the printing plate is temporarily transferred to the blanket cylinder. Then, the pattern transferred to the blanket cylinder is printed on the traveling web. The printing plate is a plate-like member made of, for example, aluminum and attached to the plate cylinder. Further, the plate mounting operation will be briefly described. When the plate is mounted, one end side (the holding side) of the plate is engaged with one end portion of the gap formed in the plate cylinder, and the plate cylinder is connected to the plate cylinder. Wrap around. Then, the other end side (the grip end side) of the printing plate is pushed into the gap, and the other end portion is fixed by a clamp device. As a result, the printing plate is fixed while being wound around the plate cylinder. Similarly to the plate cylinder, a rubber plate to which a pattern is transferred is provided on the outer peripheral surface of the blanket cylinder, and a gap similar to the gap of the plate cylinder is formed. As described above, in the normal offset printing press, since the gap as described above exists, a pattern cannot be formed in the gap portion. For this purpose, like the release agent layer of the concealment paper piece, a release agent layer is also provided in the gap part, and if a release agent layer is required continuously in the vertical direction of the concealment paper piece, a separate printing unit is used. Thus, a continuous release agent layer is provided by printing a release agent layer in the gap portion. However, when a printing misregistration of the release agent layer occurs, a part where the release agent layer does not exist is generated in a part of the concealment paper piece. In particular, when the part where the release agent layer does not exist coincides with the peeling start position of the concealment paper piece, when the recipient of the concealment postcard attempts to open the concealment paper piece, the part without the release agent layer becomes the transparent substrate. The cover sheet is strongly bonded, and the cover sheet piece is torn.

図１に示すように本発明の隠蔽葉書１は、基紙２の略中央に設けられたミシン目３（折目線に対応）を介して、葉書本体片１０と隠蔽用紙片２０とが折畳み可能に連接されている。   As shown in FIG. 1, the concealment postcard 1 of the present invention can be folded into a postcard body piece 10 and a concealment paper piece 20 via a perforation 3 (corresponding to a crease line) provided substantially at the center of the base paper 2. It is connected to.

そして、葉書本体片１０の上面には、情報記入欄１１が設けられている。また、隠蔽用紙片２０の上面には、透明シート２１と剥離紙２２とが順次重ねられ、剥離紙２２の表面には隠蔽葉書１の使用説明や剥離紙２２の剥離箇所の指示等が印刷されている。   An information entry field 11 is provided on the upper surface of the postcard body piece 10. Further, the transparent sheet 21 and the release paper 22 are sequentially stacked on the upper surface of the concealment paper piece 20, and the usage instructions of the concealment postcard 1, the instruction of the separation location of the release paper 22, etc. are printed on the surface of the release paper 22. ing.

図２を用いて、本発明の隠蔽葉書の構成を詳しく説明する。図２に示すように、隠蔽用紙片２０の上面には、ミシン目３に近接する一部分を除き（以下、強接着部２６と呼称する）、剥離剤層２３を設け、さらに接着剤層２４を介して、透明シート２１が強接着部２６を除き剥離可能に積層されている。剥離剤層２３はウレタンアクリレート、アクリレート等を主成分とするＵＶインキでパターン状にオフセット印刷、活版印刷等により形成される。剥離性は前記ＵＶインキにシリコン系の材料を適宜に添加して調整してもよい。また、隠蔽性が要求される場合には、前記のＵＶインキに墨、セピア等の濃色あるいはそれらの混色で剥離剤層に着色し、着色剥離剤層にできる。接着剤層２４は酢酸ビニル系やアクリル系やあるいはその混合系や合成ゴム系等の合成樹脂エマルジョンタイプなどの接着剤が使用される。さらに、該透明シート２１の上面には、透明な粘着剤層２５が設けられ、その上面に剥離紙２２が剥離可能に貼付されている。粘着剤層２５に用いる粘着剤は、アクリル系、ゴム系等が使用され、エマルジョンタイプ、溶剤タイプいずれでもよい。該透明シート２１の基材にはグラシン紙等の透明性のある紙やプラスチックフィルムや不織布が用いられるが、廃棄性、分別回収性の面からグラシン紙等の紙基材が望ましい。また、強接着部２６は透明シート２１の下面の一部と隠蔽用紙片２０の上面の一部が直接、接着され、剥離困難に接着されている。該強接着部２６を設けることにより、隠蔽葉書１の使用者が、剥離紙２２を剥離する際に、剥離紙２２のミシン目３に近接した端部から指で剥離紙２２を剥離したときに剥離紙２２のみが容易に剥離でき、透明シート２１が基紙２から誤って剥離されないように保護されている。また、隠蔽用紙片の下面には、ベタ印刷あるいは地紋印刷などを施してもよく隠蔽性の要求度合いから適宜選択すればよい。   The configuration of the concealment postcard according to the present invention will be described in detail with reference to FIG. As shown in FIG. 2, on the upper surface of the concealment sheet piece 20, a part close to the perforation 3 is removed (hereinafter referred to as a strong adhesion portion 26), a release agent layer 23 is provided, and an adhesive layer 24 is further provided. The transparent sheet 21 is laminated so as to be peeled except for the strong adhesion portion 26. The release agent layer 23 is formed by offset printing, letterpress printing or the like in a pattern with UV ink mainly composed of urethane acrylate, acrylate or the like. The peelability may be adjusted by appropriately adding a silicon-based material to the UV ink. Further, when concealment is required, the above-mentioned UV ink can be colored in the release agent layer with a dark color such as black or sepia or a mixed color thereof to form a colored release agent layer. For the adhesive layer 24, an adhesive such as a vinyl acetate type, an acrylic type, a mixed type thereof, or a synthetic resin emulsion type such as a synthetic rubber type is used. Further, a transparent pressure-sensitive adhesive layer 25 is provided on the upper surface of the transparent sheet 21, and a release paper 22 is detachably attached to the upper surface of the transparent sheet 21. The pressure-sensitive adhesive used for the pressure-sensitive adhesive layer 25 is acrylic or rubber-based, and may be either an emulsion type or a solvent type. Transparent paper such as glassine paper, plastic film, and non-woven fabric are used as the base material of the transparent sheet 21, but a paper base material such as glassine paper is desirable from the viewpoints of discardability and separation and recovery. Further, in the strong adhesion portion 26, a part of the lower surface of the transparent sheet 21 and a part of the upper surface of the concealment paper piece 20 are directly adhered, and are adhered to each other with difficulty in peeling. By providing the strong adhesion portion 26, when the user of the concealment postcard 1 peels the release paper 22, the user peels the release paper 22 with a finger from the end of the release paper 22 close to the perforation 3. Only the release paper 22 can be easily peeled off, and the transparent sheet 21 is protected from being accidentally peeled off from the base paper 2. Further, the lower surface of the concealment sheet piece may be subjected to solid printing or tint block printing, and may be selected as appropriate from the degree of concealment required.

次に、図３を用いて、本発明の要部を説明する。図３に示すように、隠蔽用紙片２０の基紙２の上面には、剥離剤層２３が設けられ、隠蔽用紙片２０の上端部２７及び下端部２８の両端部には数ミリ程度の幅で帯状に剥離剤層２３の上面に剥離剤層２３’、２３’が積層されている。さらに接着剤層２４を介して、透明シート２１が剥離可能に積層されている。該透明シート２１の上面には、透明な粘着剤層２５が設けられ、その上面に剥離紙２２が剥離可能に貼付されている。隠蔽用紙片の上端部と下端部に２層積層された剥離剤層が設けられることにより、郵送された隠蔽葉書を受取人が開封する際に、隠蔽用紙片の破れがなく、且つ、容易に開封できるものである。隠蔽用紙片２０の上端部２７及び下端部２８の両端部に設けられる帯状の剥離剤層２３’、２３’の幅は、容易に剥離できれば特に限定されるものではないが、２〜３ミリが望ましい。尚、本発明の実施形態では、図２に示したように、透明シート２１の下面側における一側端縁部に、該透明シート２１の下面の一部と、前記隠蔽用紙片２０の基紙２の上面の一部とが直接接着されている例を示したが、前記のような直接接着されている部分を設けなくても同じ効果が得られるものである。   Next, the main part of the present invention will be described with reference to FIG. As shown in FIG. 3, a release agent layer 23 is provided on the upper surface of the base paper 2 of the concealing paper piece 20, and a width of about several millimeters is provided at both ends of the upper end portion 27 and the lower end portion 28 of the concealing paper piece 20. The release agent layers 23 ′ and 23 ′ are laminated on the upper surface of the release agent layer 23 in a band shape. Further, the transparent sheet 21 is detachably laminated via the adhesive layer 24. A transparent pressure-sensitive adhesive layer 25 is provided on the upper surface of the transparent sheet 21, and a release paper 22 is detachably attached to the upper surface. By providing two layers of release agent layers on the upper and lower ends of the concealment paper piece, the concealment paper piece is not torn when the recipient opens the concealment postcard that has been mailed. It can be opened. The widths of the strip-like release agent layers 23 ′ and 23 ′ provided at both end portions of the upper end portion 27 and the lower end portion 28 of the concealment paper piece 20 are not particularly limited as long as they can be easily peeled, but are 2 to 3 mm. desirable. In the embodiment of the present invention, as shown in FIG. 2, a part of the lower surface of the transparent sheet 21 and the base paper of the concealment paper piece 20 are formed on one side edge on the lower surface side of the transparent sheet 21. Although an example in which a part of the upper surface of 2 is directly bonded is shown, the same effect can be obtained without providing a directly bonded portion as described above.

次に、オフセット輪転印刷機を用いて印刷による剥離剤層２３、２３’の積層例について説明する。図４に、隠蔽葉書を１列（ウェブの走行方向と直交する方向）、２面（ウェブの流れ方向）付けで隠蔽葉書Ａ、Ｂの剥離剤層を２色印刷した例を示した。図中において、隠蔽葉書の剥離剤層が１層部分の流れ方向の寸法をｈ、隠蔽葉書の上端部及び下端部に設けられた剥離剤層２層積層された部分の流れ方向の寸法をｗ、隠蔽葉書の上端部から下端部までの寸法をｙとして示した。また、剥離剤層の印刷部分を斜線で示した。１色目の剥離剤層印刷版には、隠蔽葉書Ａの剥離剤層印刷部を流れ方向寸法でａ＝２ｗ＋ｈ＋２ｗ、非印刷部（隠蔽葉書Ｂの剥離剤層１層部に相当）を流れ方向寸法でｈを設けた。２色目の剥離剤層印刷版には、非印刷部（隠蔽葉書Ａの剥離剤層１層部に相当）を流れ方向寸法でｈ、隠蔽葉書Ｂの剥離剤層印刷部を流れ方向寸法でｂ＝２ｗ＋ｈ＋２ｗを設けた。１色目の印刷ユニットで隠蔽葉書Ａの剥離剤層を印刷し、次の印刷ユニットで隠蔽葉書Ｂの剥離剤層を隠蔽葉書Ａの剥離剤層に剥離剤層が流れ方向寸法２ｗ重なるように見当を合わせて印刷し、以後、繰返し印刷される。そうすることにより、基紙ウェブの流れ方向に剥離剤層１層部（ｈ）と剥離剤層２層重なり部（２ｗ）とが連続して、交互に印刷形成される。該剥離剤層２層重なり部２ｗの流れ方向の中点Ａ1から次の重なり部２ｗの中点Ｂ1までを隠蔽葉書Ｂとし、さらに、次の中点Ａ2までを隠蔽葉書Ａとする。そうすることにより、上端部及び下端部に剥離剤層が２層積層された隠蔽葉書が寸法ｙ＝（ｗ＋ｈ＋ｗ）で形成されるものである。 Next, a lamination example of the release agent layers 23 and 23 ′ by printing using an offset rotary printing press will be described. FIG. 4 shows an example in which the release agent layers of the concealment postcards A and B are printed in two colors with one row of concealment postcards (direction perpendicular to the running direction of the web) and two sides (web flow direction).
