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開封され盗み見された場合、その事実が残り確認可能であり、また第三者に開封されることを未然に防ぐことが可能な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, before the mailed postcard is delivered to the recipient, the information written on the postcard is opened and stolen by a third party. In this case, it is related to a concealment postcard in which the fact can be confirmed and can be prevented from being opened by a third party.

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及び２参照）。   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. An information concealment postcard preparation sheet piece provided with a transparent sheet having a transparent adhesive on both sides of the bonded material is known (see, for example, Patent Documents 1 and 2).

しかしながら、上記の特許文献１及び２に開示された隠蔽葉書は、葉書本体片に記入された情報を隠蔽状態にするために、剥離紙を剥離して、粘着剤層を露出させ、その後、折り用ミシンで折畳み葉書本体片に記入された情報を隠蔽して郵送されるものであり、隠蔽する際に、葉書本体片と略同サイズの隠蔽用紙片の全面に設けられた粘着剤層面を情報を記入した葉書本体片に折畳みながら隠蔽するときに、折り曲がり等により、隠蔽用紙片と葉書本体片との貼り位置ズレが起こり、粘着剤が露出した状態になる部分が発生する場合がある。このような隠蔽葉書は、例えば、郵便局で郵便区分け機などの機械処理がされると、露出した粘着剤面が他の郵便物に粘着しトラブルとなったり、著しい場合には、郵便物の重送などのトラブルになるという問題がある。   However, the concealment postcards disclosed in the above-mentioned patent documents 1 and 2 peel off the release paper to expose the pressure-sensitive adhesive layer in order to conceal the information written on the postcard body piece, and then fold it. The information written on the folded postcard body piece is concealed with a sewing machine and mailed. When concealing, the adhesive layer surface provided on the entire surface of the concealed paper piece of the same size as the postcard body piece is information. When concealing while folding on a postcard body piece in which is written, there is a case where a sticking position shift between the concealment paper piece and the postcard body piece occurs due to bending or the like, and a part where the adhesive is exposed may occur. Such concealed postcards, for example, when the post office is subjected to mechanical processing such as a postal sorting machine, the exposed adhesive surface sticks to other postal items and causes troubles. There is a problem of trouble such as double feeding.

また、上記の特許文献１及び２に開示された隠蔽葉書は、葉書本体片と隠蔽用紙片とは連接されているために、同質の紙が使用されている。そのために隠蔽用紙片のみの坪量を下げることができないためコストダウンを図ることができず、また、高い隠蔽性が求められる場合にも隠蔽用紙片は葉書本体片と同じ坪量であるため限界があり、十分な隠蔽性は得られないという欠点がある。
特開平１０−２６４５５９号公報 特開２００４−９７２０号公報 The concealing postcards disclosed in Patent Documents 1 and 2 described above use the same type of paper because the postcard body piece and the concealing paper piece are connected. For this reason, the basis weight of only the concealment paper piece cannot be reduced, so the cost cannot be reduced, and the concealment paper piece has the same basis weight as the postcard body piece even when high concealment is required. There is a drawback that sufficient concealment cannot be obtained.
JP-A-10-264559 JP 2004-9720 A

本発明は、上記のような従来の問題点に鑑み、情報を記入した葉書本体片を隠蔽用紙片で隠蔽する際に、貼り位置ズレが発生しても、粘着面がはみ出して露出することがなく、また、隠蔽用紙片の坪量を葉書本体片の坪量に対しコントロールし、コストダウンを図ることができ、さらに、受取人が開封し易い隠蔽葉書を提供するものである。   In the present invention, in view of the conventional problems as described above, when the postcard body piece on which information is written is concealed with a concealment paper piece, even if a sticking position shift occurs, the adhesive surface may protrude and be exposed. In addition, the basis weight of the cover sheet piece can be controlled with respect to the basis weight of the post card body piece, the cost can be reduced, and a cover post card that is easy for the recipient to open is provided.

FIG. 6 is a cross-sectional view showing a state in which a postcard recipient is spread apart by a recipient of the postcard in one embodiment of the present invention, and FIG. 7 is another view of the present invention. It is sectional drawing equivalent to the BB line of FIG. 3 which shows embodiment.

図１に示すように本発明の隠蔽葉書１は、一端に綴じ部３を設けた葉書本体片２と綴じ部３に平行な辺の縦寸法と綴じ部３に直交する辺の横寸法が葉書本体片２よりも共に短い寸法の隠蔽用紙片１０とが基紙１１の一端に設けられた綴じ部３で揃えて、接着されている。そして、葉書本体片２の上面には、情報記入欄４（図３参照）が設けられている。また、隠蔽用紙片１０は基紙１１の下面に、透明シート１２と剥離紙１３とが順次重ねられて構成され、剥離紙１３の表面には隠蔽葉書１の使用説明や剥離紙１３の剥離箇所の指示等が印刷されている（図３参照）。   As shown in FIG. 1, the concealed postcard 1 of the present invention has a postcard body piece 2 provided with a binding portion 3 at one end, a vertical dimension of a side parallel to the binding portion 3, and a horizontal dimension of a side orthogonal to the binding portion 3. A concealment paper piece 10 having a shorter dimension than the main body piece 2 is aligned and bonded by a binding portion 3 provided at one end of the base paper 11. An information entry field 4 (see FIG. 3) is provided on the upper surface of the postcard body piece 2. Further, the concealment paper piece 10 is configured by sequentially laminating a transparent sheet 12 and a release paper 13 on the lower surface of the base paper 11. Are printed (see FIG. 3).

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１０は、基紙１１の下面に、一端より綴じ部３、着色剥離剤層１５が設けられ、さらに綴じ部３と着色剥離剤層１５との間に一部着色剥離剤の未コート部（以下、強接着部と呼称する）を設け、強接着部１４及び着色剥離剤層１５の面に形成された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を使用した接着剤層１６を介して、透明シート１２が強接着部１４を除き剥離可能に積層されている。着色剥離剤層１５は墨、セピア等の濃色あるいはそれらの混色で着色された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ている。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。このように着色剥離剤層１５を設けることにより、隠蔽用紙片１０の隠蔽性が著しく向上し、隠蔽用紙片１０を構成する基紙１１の坪量を葉書本体片２より下げることが可能となり、コストダウンが図れる。また、高い隠蔽性が求められる場合には、隠蔽用紙片１０を構成する基紙１１の坪量を葉書本体片２より上げることが可能となり、隠蔽用の印刷を施さずに隠蔽性を向上させることができる。この場合には剥離剤層は通常のものを使用できる。さらに透明シート１２の下面に透明な粘着剤層１７を介して、剥離紙１３が剥離可能に貼付されている。粘着剤層１７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。透明シート１２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、基紙１１の一端に設けられた綴じ部３は葉書本体片２に設けられた綴じ部３を対向させて接着剤５で接着されている。基紙１１の綴じ部３と強接着部１４との間にミシン目１８が設けられ、隠蔽用紙片１０が該ミシン目１８で折返して見開き可能になっている（図３参照）。また、隠蔽用紙片１０の基紙１１の上面には、ベタ印刷あるいは地紋印刷などを施して隠蔽性が付与されている。次に、図３、図４を用いて強接着部１４の作用について説明する。図４に示すように強接着部１４は透明シート１２の下面の一部と基紙１１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１４を設けることにより、隠蔽葉書１の使用者が、剥離紙１３を剥離する際に、図３に示すように見開き状態にして綴じ部３に近接した端部から指で剥離紙１３を剥離したときに剥離紙１３のみが容易に剥離でき、透明シート１２が基紙１１から誤って剥離されないように保護されている。   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, the concealment paper piece 10 is provided with a binding portion 3 and a colored release agent layer 15 from one end on the lower surface of the base paper 11, and further between the binding portion 3 and the colored release agent layer 15. An uncoated part (hereinafter referred to as a strong adhesive part) of a partly colored release agent is provided, and a vinyl acetate type, an acrylic type, or a mixed system or a synthesis thereof formed on the surfaces of the strong adhesive part 14 and the colored release agent layer 15 A transparent sheet 12 is laminated in a peelable manner except for the strong adhesion portion 14 via an adhesive layer 16 using an adhesive such as a rubber-based synthetic resin emulsion type. The colored release agent layer 15 is formed by offset printing, letterpress printing, or the like in a pattern with a UV ink mainly composed of urethane acrylate, acrylate, or the like colored with a dark color such as black or sepia, or a mixed color thereof. The peelability may be adjusted by appropriately adding a silicon-based material to the UV ink. By providing the colored release agent layer 15 in this way, the concealment property of the concealment paper piece 10 is remarkably improved, and the basis weight of the base paper 11 constituting the concealment paper piece 10 can be lowered from the postcard body piece 2. Cost can be reduced. When high concealment is required, the basis weight of the base paper 11 constituting the concealment paper piece 10 can be increased from the postcard body piece 2 and the concealment can be improved without performing concealment printing. be able to. In this case, a normal release agent layer can be used. Further, a release paper 13 is detachably attached to the lower surface of the transparent sheet 12 via a transparent adhesive layer 17. The pressure-sensitive adhesive used for the pressure-sensitive adhesive layer 17 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 12, but a paper base material such as glassine paper is desirable from the viewpoint of discardability and separation and recovery. Further, the binding portion 3 provided at one end of the base paper 11 is bonded with an adhesive 5 so as to face the binding portion 3 provided on the postcard body piece 2. A perforation 18 is provided between the binding portion 3 and the strong adhesion portion 14 of the base paper 11, and the concealment paper piece 10 can be folded back at the perforation 18 so as to be spread (see FIG. 3). Further, the upper surface of the base paper 11 of the concealment paper piece 10 is provided with concealability by performing solid printing or tint block printing. Next, the effect | action of the strong adhesion part 14 is demonstrated using FIG. 3, FIG. As shown in FIG. 4, in the strong adhesion portion 14, a part of the lower surface of the transparent sheet 12 and a part of the upper surface of the base paper 11 are directly adhered, and are adhered to each other with difficulty in peeling. By providing the strong adhesion portion 14, when the user of the concealment postcard 1 peels the release paper 13, the release paper 13 is spread with a finger from the end close to the binding portion 3 as shown in FIG. 3. Only the release paper 13 can be easily peeled off when 13 is peeled off, and the transparent sheet 12 is protected from being accidentally peeled off from the base paper 11.

次に、図３〜６を用いて本発明の実施形態に係る隠蔽葉書を使用する手順について説明する。まず、隠蔽葉書１の利用者は、図３及び図４に示すように、隠蔽用紙片１０に設けられたミシン目１８で隠蔽用紙片１０を折り返して見開き状態にする。葉書本体片２に設けられた情報記入欄４に個人情報等の必要事項を記入し、必要に応じて、葉書本体片２の下面に設けられた宛先記入欄を記入する。次に、剥離紙１３の綴じ部３に近接する一端部を指で掴み剥離紙１３を剥離し、粘着剤層１７を露出させる。この場合、前述の通り、強接着部１４により透明シート１２が基紙１１から誤って剥離されないように保護させている。その後、隠蔽用紙片１０をミシン目１８より折畳んで、図５に示すように、粘着剤層１７の面を葉書本体片２に設けられた情報記入欄４に重ね合わせて接着することにより情報記入欄４が隠蔽される。そして、単体葉書として投函すればよい。   Next, the procedure for using the concealment postcard according to the embodiment of the present invention will be described with reference to FIGS. First, as shown in FIGS. 3 and 4, the user of the concealment postcard 1 folds the concealment sheet piece 10 at the perforation 18 provided in the concealment sheet piece 10 to make it spread. The necessary information such as personal information is entered in the information entry field 4 provided on the postcard body piece 2, and the address entry field provided on the lower surface of the postcard body piece 2 is entered as necessary. Next, one end of the release paper 13 that is close to the binding portion 3 is grasped with a finger to release the release paper 13 to expose the adhesive layer 17. In this case, as described above, the strong adhesive portion 14 protects the transparent sheet 12 from being accidentally separated from the base paper 11. Thereafter, the concealment paper piece 10 is folded from the perforation 18, and the surface of the pressure-sensitive adhesive layer 17 is superimposed on the information entry column 4 provided on the postcard body piece 2 and adhered as shown in FIG. The entry field 4 is hidden. Then, post it as a single postcard.

次に、この葉書を受け取った受取人は、図６に示すように隠蔽用紙片１０の一端部を摘んで剥離すると、隠蔽用紙片１０の基紙１１に設けられている着色剥離剤層１５と接着剤層１６との界面から剥離され、葉書本体片２の情報記入欄４に記載された内容を、接着剤層１６／透明シート１２／粘着剤層１７を透して視認できるものである。また、接着剤層１６と着色剥離剤層１５とは再接着が困難なために、第三者に開封され盗み見された場合、その事実が残り確認可能であり、また第三者に開封されることを未然に防ぐことが可能となるものである。   Next, when the recipient who has received this postcard picks up one end portion of the concealment paper piece 10 and peels it off as shown in FIG. 6, the color release agent layer 15 provided on the base paper 11 of the concealment paper piece 10 and The content peeled off from the interface with the adhesive layer 16 and described in the information entry field 4 of the postcard body piece 2 can be seen through the adhesive layer 16 / transparent sheet 12 / adhesive layer 17. In addition, since the adhesive layer 16 and the colored release agent layer 15 are difficult to re-adhere, when the third party opens and steals the fact, the fact can be confirmed and the third party opens it. This can be prevented in advance.

次に、図７を用いて、本発明の他の実施形態について説明する。前記の実施形態と構成及び機能が異なる部分のみ符号を変え、同じ部分は同符号を用い重複する部分は説明を省略する。図７に示すように、基紙１１の片面の一端に綴じ部３が設けられ、ミシン目１８を介して接着剤層２６が形成され、下面に剥離剤層２５を設けた透明シート２２が積層され、上面に透明な粘着剤層１７を介して、剥離紙１３が剥離可能に貼付されている。さらに透明シート２２の下面にはミシン目１８に近接する側の一端に剥離剤の未コート部（以下、強接着部と呼称する）が設けられている。剥離剤層２５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透明なＵＶインキを用いて、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。尚、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、強接着部２４は透明シート２２の下面の一部と基紙１１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２４を設けることにより、隠蔽葉書１の使用者が、剥離紙１３を剥離する際に、剥離紙１３のミシン目１８に近接した端部から指で剥離紙１３を剥離したときに剥離紙１３のみが容易に剥離でき、透明シート２２が基紙１１から誤って剥離されないように保護されている。該隠蔽葉書１の使用方法は前述の説明通りであるが、この隠蔽葉書を受け取った受取人は、隠蔽用紙片１０の一端部を摘んで、剥離すると隠蔽用紙片１０の基紙１１に形成されている接着剤層２６と、透明シート２２に設けられている剥離剤層２５との界面から剥離され、葉書本体片２の情報記入欄４に記載された内容を、剥離剤層２５／透明シート２２／粘着剤層１７を透して視認できるものである。尚、本発明の実施形態では、透明シート１２、２２の一側端縁部に強接着部１４、２４を設けて、前記隠蔽用紙片１０の基紙１１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, another embodiment of the present invention will be described with reference to FIG. Only the parts different in configuration and function from the above embodiment are changed, and the same parts are denoted by the same reference numerals, and the description of the overlapping parts is omitted. As shown in FIG. 7, a binding sheet 3 is provided at one end of one side of the base paper 11, an adhesive layer 26 is formed through a perforation 18, and a transparent sheet 22 having a release agent layer 25 provided on the lower surface is laminated. The release paper 13 is detachably attached to the upper surface via a transparent adhesive layer 17. Further, an uncoated portion (hereinafter, referred to as a strong adhesion portion) of a release agent is provided on one end of the transparent sheet 22 on the side close to the perforation 18. The release agent layer 25 is formed in a pattern by offset printing, letterpress printing or the like using a transparent 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, in the strong adhesion portion 24, a part of the lower surface of the transparent sheet 22 and a part of the upper surface of the base paper 11 are directly adhered to each other so that they are difficult to peel. By providing the strong adhesion portion 24, when the user of the concealment postcard 1 peels the release paper 13, the user peels the release paper 13 from the end of the release paper 13 near the perforation 18 with a finger. Only the release paper 13 can be easily peeled off, and the transparent sheet 22 is protected from being accidentally peeled off from the base paper 11. The method of using the concealment postcard 1 is as described above. The recipient who has received this concealment postcard picks up one end of the concealment paper piece 10 and peels it off to form it on the base paper 11 of the concealment paper piece 10. The adhesive layer 26 is peeled off from the interface between the release agent layer 25 provided on the transparent sheet 22 and the content described in the information entry field 4 of the postcard body piece 2 is changed to the release agent layer 25 / transparent sheet. 22 / The adhesive layer 17 can be seen through. In the embodiment of the present invention, strong adhesion portions 14 and 24 are provided at one side edge portions of the transparent sheets 12 and 22 so that a part of the base paper 11 of the concealment paper piece 10 is directly adhered. Although an example has been shown, the same effect can be obtained without providing a directly bonded portion as described above.
