Description

本発明は、記載された通知情報の親展性の高い圧着葉書に関し、特にくじ付郵便葉書に関するものである。   The present invention relates to a postcard with lottery, and particularly to a postcard with lottery.

従来の他人が通知情報を視認できないようにした圧着葉書としては、2つ折り形態と3つ折り形態の葉書が広く知られている。2つ折り形態としては、折り目部よりミシン目線によって分離できる2つ折り葉書であって、その見開きの片面部には、例えば証明、依頼等の事項を表示するとともに、他面部には、上記の事項を控として表示し、これらの表示部が対向するように折り合わせ、その重なり合う面の表示面に予め形成した剥離可能な粘着剤層により貼着した控付き隠蔽葉書が知られている(例えば、特許文献1参照)。3つ折り形態としては、基材の密着予定面の全面に弱粘着剤層を形成したシークレットはがき用などとして使用するメールフォームに関し、秘密情報等を印字した密着面の側縁部に剥離不可能な強接着剤層と、開封用のミシン目およびコーナーカットを設けたセキュリティーメールフォームが知られている(例えば、特許文献2参照)。   2. Description of the Related Art Conventionally, as post-crimp postcards in which notification information cannot be viewed by others, two-fold and three-fold postcards are widely known. As a two-fold form, it is a two-fold postcard that can be separated from the crease line by a perforation line. On one side of the spread, for example, items such as proof and request are displayed, and on the other side, the above items are displayed. There are known concealed postcards that are displayed as stickers, folded so that these display parts face each other, and pasted on a display surface of the overlapping surfaces by a pre-formed peelable adhesive layer (for example, patents) Reference 1). As a tri-fold form, a mail form used for a secret postcard or the like in which a weak adhesive layer is formed on the entire surface of the base material to be adhered cannot be peeled off on the side edge of the adhesive surface on which secret information is printed. A security mail form provided with a strong adhesive layer, an opening perforation and a corner cut is known (for example, see Patent Document 2).

しかしながら、上記2つ折り形態と3つ折り形態の圧着葉書はいずれも2つ折りもしくは3つ折りして葉書の大きさになるようにそれぞれの紙片が連接された一枚の用紙で構成されているために、この形態を例えばお年玉付年賀葉書やくじ付暑中葉書(かもめーる)等の抽選番号が付いたくじ付郵便葉書に適用すると、紙片は独立していなければならないという当たり、はずれの抽選番号の付いた官製葉書等に関する規定により制約を受け、くじ付郵便葉書には適用できないという問題がある。くじ付郵便葉書に適用するには、それぞれの紙片が独立していることが必要となる。一方、独立した紙片からなる圧着葉書としては、葉書本体の片面に接着層を介してシート片が剥離可能に積層され、該シート片を剥離することにより隠蔽情報が表出するように成した隠蔽葉書が知られている(例えば、特許文献3参照)。   However, since the above-mentioned two-fold and three-fold crimped postcards are composed of a single sheet in which each piece of paper is connected so that the size of the postcard is folded in two or three. When this form is applied to a lottery postcard with a lottery number, such as a New Year postcard with a New Year's card or a lottery card (Kamoru), the piece of paper must be independent. There is a problem that it cannot be applied to lottery postcards due to restrictions imposed by government-related postcards. To apply to lottery postcards, each piece of paper must be independent. On the other hand, as a crimped postcard made up of independent paper pieces, a concealment is formed such that a sheet piece is detachably laminated on one side of the postcard body via an adhesive layer, and concealment information is revealed by peeling the sheet piece A postcard is known (for example, refer to Patent Document 3).

しかしながら、特許文献3の隠蔽葉書は、ワックスエマルジョンと酢酸ビニルアクリル共重合体エマルジョンの混合物から構成された接着層からなり、酢酸ビニルアクリル共重合体エマルジョンは接着層の接着力を調整するために添加されるものであり、配合比率が小さくなると接着力が弱まり、配達中において葉書本体とシート片が分離する恐れが有るという問題がある。
一方、くじ付郵便葉書を用いることにより、受信人は記載された情報を見た後、少なくとも抽選日までは捨てることなく保管をするので、抽選日には再び記載された情報が受信者の目に触れるという効果が期待でき、例えば商品の情報であれば、その商品の販促効果の継続性を高めることができるという発信人である販売者、メーカー等のニーズがあり、親展性の高いくじ付郵便葉書の開発が要望されていた。
However, the concealment postcard of Patent Document 3 is composed of an adhesive layer composed of a mixture of a wax emulsion and a vinyl acetate acrylic copolymer emulsion, and the vinyl acetate acrylic copolymer emulsion is added to adjust the adhesive strength of the adhesive layer. However, when the blending ratio is small, the adhesive strength is weakened, and there is a problem that the postcard body and the sheet piece may be separated during delivery.
On the other hand, by using a postcard with lottery, the recipient sees the written information and keeps it at least until the lottery date. For example, if it is product information, there is a need from the seller, manufacturer, etc. who can improve the continuity of the sales promotion effect of the product, and the lottery with high confidentiality There was a demand for the development of postcards.

FIG. 7 is a cross-sectional view showing a second embodiment of the postcard with lottery according to the present invention, and FIG. 7 (a) is a cross-sectional view corresponding to the line XX of FIG. FIG. 7B is a cross-sectional view showing a state where the package is opened and spread.
As shown in FIG. 7 (a), the lottery postcard 101 of the second embodiment has a lottery number written on the outer surface of the postcard body piece 2, confidential information written on the inner surface, and the postcard body piece on the inner surface of the postcard body piece. A postcard with a lottery that overlaps the inner surface of a concealment paper piece and is releasably stacked to conceal confidential information described on the inner surface of the postcard body piece, the inner surface of the postcard body piece 2 and the inner surface of the concealment paper piece 3 However, through a pseudo-adhesive sheet 105 in which heat-sensitive adhesive layers 104 and 104 are provided on both sides of a sheet formed by laminating a release resin layer 103 that can be peeled off from the transparent plastic sheet layer 102 on one side of the transparent plastic sheet layer 102. In this configuration, they are superposed, heat bonded and integrated. The transparent plastic sheet layer 102 and the release resin layer 103 can be peeled off.
Then, at one side edge 5 of the long side of the postcard body piece 2 and the concealment paper piece 3, the pseudo adhesive sheet 105 is retracted inward of the postcard 101 with lottery to conceal the inner surface of the postcard body piece 2. A side edge heat-sensitive adhesive layer 106 is formed at a portion directly facing the inner surface of the sheet piece 3, and the postcard body piece 2 and the concealment sheet piece 3 are heat-bonded at the side edge portion 5 so as not to be peeled off. By providing the side edge heat-sensitive adhesive 106, the postcard body piece 2 and the concealment paper piece 3 are not separated during mail sorting or delivery. The direction in which the pseudo adhesive sheet 105 is overlapped between the postcard main body piece 2 and the concealment paper piece 3 is not particularly limited, but the transparent plastic sheet layer 102 of the pseudo adhesive sheet 105 is disposed on the postcard main body piece 2 side and the release resin layer 103. Is laminated so that the cover sheet 3 is on the side of the concealment paper piece 3, and can be easily opened in a spread state when the postcard 101 with a fold is peeled off between the transparent plastic sheet 102 and the release resin layer 103. Therefore, it is preferable.

上記のように構成されたくじ付郵便葉書101を受取った受取人は、切り欠き30より隠蔽用紙片3と葉書本体片2を摘んで、透明プラスチックシート層102と離型樹脂層103との界面から剥離させ、図7(ロ)に示すようにミシン目線31で隠蔽用紙片3を折り返して見開き状態にすることにより、葉書本体片2の内面に記載された親展情報Sを透明プラスチックシート層102および感熱接着剤層104を透して読み取ることができ、隠蔽用紙片3の内面に記載された親展情報Sを離型樹脂層103および感熱接着剤層104を透して読み取ることができる。   The recipient who has received the postcard 101 with a lottery constructed as described above picks up the concealment paper piece 3 and the postcard body piece 2 from the notch 30, and interfaces between the transparent plastic sheet layer 102 and the release resin layer 103. As shown in FIG. 7 (b), the concealment paper piece 3 is folded back at the perforation line 31 so as to be spread, so that the confidential information S written on the inner surface of the postcard body piece 2 is transferred to the transparent plastic sheet layer 102. The confidential information S written on the inner surface of the concealment paper piece 3 can be read through the release resin layer 103 and the heat-sensitive adhesive layer 104.

また、第二実施形態も第一実施形態と同じ効果を奏し、くじ付郵便葉書であるので受信人は記載された親展情報Sを見た後、少なくとも抽選日までは捨てることなく保管されることとなり、抽選日にはくじ付郵便葉書101の葉書本体片2及び隠蔽用紙片3の内面に記載された親展情報Sと外面に記載されたオープン情報Oが再び受取人の目に触れることとなり、例えば、商品情報であれば、その商品の販促効果の継続性を高めることが可能となる。   Also, the second embodiment has the same effect as the first embodiment, and since it is a postcard with lottery, the recipient should keep it at least until the lottery date after viewing the confidential information S described. Then, on the lottery day, the confidential information S written on the inner surface of the postcard body piece 2 and the concealment paper piece 3 with lottery and the open information O written on the outer surface will again be seen by the recipient, For example, in the case of product information, it is possible to improve the continuity of the sales promotion effect of the product.

つぎに、第二実施形態のくじ付郵便葉書101に使用する擬似接着シート105について説明する。擬似接着シート105を構成する透明プラスチックシート層102に使用される透明プラスチックシートとしては、ポリエチレンテレフタレート、ポリプロピレン、ポリエチレン、ポリスチレン、アセテート、ポリ乳酸等を挙げることができるが、これらの内、特に、耐熱性、寸法安定性等の性能面及び価格面を勘案するとポリエチレンテレフタレートが好ましい。また、透明プラスチックシートは、未延伸フィルムより二軸延伸フィルムの方が耐熱性、寸法安定性等の性能面がより優れているので好ましい。透明プラスチックシートの厚さは、6〜50μmが好ましい。厚さ6μ未満では、離型樹脂層103、または感熱接着剤層104を積層する際に、透明プラスチックシートに皺が発生し、生産性や品質の低下を招き、厚さが50μmを超えると価格が高くなったり、くじ付郵便葉書を開封した際、見開き状態の保持が難しくなる。   Next, the pseudo-adhesive sheet 105 used for the postcard 101 with lottery according to the second embodiment will be described. Examples of the transparent plastic sheet used for the transparent plastic sheet layer 102 constituting the pseudo-adhesive sheet 105 include polyethylene terephthalate, polypropylene, polyethylene, polystyrene, acetate, polylactic acid, and the like. Polyethylene terephthalate is preferable in view of performance and price such as stability and dimensional stability. In addition, as the transparent plastic sheet, a biaxially stretched film is preferable to an unstretched film because it has more excellent performance such as heat resistance and dimensional stability. The thickness of the transparent plastic sheet is preferably 6 to 50 μm. If the thickness is less than 6 μm, when the release resin layer 103 or the heat-sensitive adhesive layer 104 is laminated, wrinkles occur in the transparent plastic sheet, resulting in a decrease in productivity and quality. When opening a postcard with lottery, it becomes difficult to maintain the spread state.

擬似接着シート105を構成する離型樹脂層103には透明プラスチックシート層102との離型性、および、離型樹脂層103に積層される感熱接着剤層104と接着性が要求される。特に、透明プラスチックシート層102との離型性は、くじ付郵便葉書101の受取人が、指で容易に剥離できると共に、受信人に配達されるまでは剥離して分離してしまうことがないという性能が要求される。さらに、親展情報Sが視認できる透明性が必要となる。   The release resin layer 103 constituting the pseudo-adhesive sheet 105 is required to have release properties from the transparent plastic sheet layer 102 and adhesiveness to the heat-sensitive adhesive layer 104 laminated on the release resin layer 103. In particular, the releasability from the transparent plastic sheet layer 102 is such that the recipient of the postcard 101 with lottery can be easily peeled off with a finger and is not peeled off until it is delivered to the recipient. Performance is required. Furthermore, the transparency which the confidential information S can visually recognize is required.

離型樹脂層103の樹脂としては、ポリエチレン、ポリプロピレン、エチレンアクリル酸エチル共重合体、エチレンメタクリル酸メチル共重合体、エチレンメタクリル酸エチル共重合体、エチレンアクリル酸共重合体、エチレンメタクリル酸共重合体、エチレン酢酸ビニル共重合体、アイオノマー、スチレンアクリル系等の公知の樹脂の単体、またはそれらの樹脂を2種以上混合した混合物を用いることができる。離型樹脂層103の形成厚さは、通常、0.5〜20μm程度である。形成厚さが0.5μm未満では、透明プラスチックシート層102と離型樹脂層103との剥離強度が不安定となる。また、形成厚さが20μmを超えると、価格が高くなる。さらに、離型樹脂層103の樹脂には親展情報Sが視認できる透明性が必要である。   Examples of the resin of the release resin layer 103 include polyethylene, polypropylene, ethylene ethyl acrylate copolymer, ethylene methyl methacrylate copolymer, ethylene ethyl methacrylate copolymer, ethylene acrylic acid copolymer, and ethylene methacrylate copolymer. A single substance of a known resin such as a polymer, an ethylene vinyl acetate copolymer, an ionomer, or a styrene acrylic resin, or a mixture of two or more of these resins can be used. The formation thickness of the release resin layer 103 is usually about 0.5 to 20 μm. When the formation thickness is less than 0.5 μm, the peel strength between the transparent plastic sheet layer 102 and the release resin layer 103 becomes unstable. Moreover, when the formation thickness exceeds 20 μm, the price increases. Further, the resin of the release resin layer 103 needs to be transparent so that the confidential information S can be visually recognized.

また、感熱接着剤層104、104には、透明プラスチックシート層102、および離型樹脂層103との接着性、親展情報Sが記載された葉書本体片2の内面、隠蔽用紙片3の内面、および親展情報Sの記載部分を加熱接着により一体化させるための感熱接着性が要求される。つまり、感熱接着剤層104と透明プラスチックシート層102との接着力をf42、感熱接着剤層104と離型樹脂層103との接着力をf43、葉書本体片2の内面と感熱接着剤層104との感熱接着力をk42、隠蔽用紙片3の内面と感熱接着剤層104との感熱接着力をk43、親展情報Sの記載部分と感熱接着剤層104との感熱接着力をk4s、透明プラスチックシート層102と離型樹脂層103との接着力をf23で表すと下記の数式を満足する感熱接着剤を用いることができる。
f23<k42、k43、k4s≦、f42、f43、
また、親展情報Sが視認できる透明性が必要である。
The heat-sensitive adhesive layers 104 and 104 have adhesiveness to the transparent plastic sheet layer 102 and the release resin layer 103, the inner surface of the postcard body piece 2 on which confidential information S is described, the inner surface of the concealment paper piece 3, In addition, heat-sensitive adhesiveness for integrating the described portions of the confidential information S by heat bonding is required. That is, the adhesive force between the heat-sensitive adhesive layer 104 and the transparent plastic sheet layer 102 is f42, the adhesive force between the heat-sensitive adhesive layer 104 and the release resin layer 103 is f43, and the inner surface of the postcard body piece 2 and the heat-sensitive adhesive layer 104. K42, the heat-sensitive adhesive force between the inner surface of the concealing paper piece 3 and the heat-sensitive adhesive layer 104, k43, the heat-sensitive adhesive force between the portion of the confidential information S and the heat-sensitive adhesive layer 104, k4s, transparent plastic When the adhesive force between the sheet layer 102 and the release resin layer 103 is represented by f23, a heat-sensitive adhesive that satisfies the following mathematical formula can be used.
f23 <k42, k43, k4s ≦, f42, f43,
Moreover, the transparency which the confidential information S can visually recognize is required.

これらの特性を有する感熱接着剤層104に使用される感熱接着剤としては、葉書本体片、擬似接着シート、隠蔽用紙片を感熱接着するのに低温領域(例えば、100℃以下)で感熱接着して一体化可能な、エチレン酢酸ビニル共重合体、塩化ビニル酢酸ビニル共重合体、ポリ酢酸ビニル系樹脂、ポリエステル系樹脂、ポリエチレン系樹脂、ポリアクリル系樹脂、塩素化ポリプロピレン系樹脂、ポリスチレン系樹脂、ウレタン系樹脂、ポリアミド系樹脂等の中から適宜選択された樹脂の単体、またはそれらの2種以上を混合した混合物を用いることができる。   The heat-sensitive adhesive used for the heat-sensitive adhesive layer 104 having these characteristics includes heat-sensitive adhesion in a low temperature region (for example, 100 ° C. or lower) for heat-bonding a postcard body piece, a pseudo-adhesive sheet, and a concealment paper piece. Can be integrated, ethylene vinyl acetate copolymer, vinyl chloride vinyl acetate copolymer, polyvinyl acetate resin, polyester resin, polyethylene resin, polyacrylic resin, chlorinated polypropylene resin, polystyrene resin, A simple substance of a resin appropriately selected from urethane-based resins, polyamide-based resins, or the like, or a mixture obtained by mixing two or more of them can be used.

擬似接着シート105は、透明プラスチックシートを基材として離型樹脂層、感熱接着剤層を積層することにより得られる。積層方法としては、透明プラスチックシートにエクストルージョン方式で樹脂を積層して設けてもよいし、樹脂をエマルジョンタイプもしくは溶液タイプまたはホットメルトにしてコーティング方式で積層してもよい。このような擬似接着シートの具体例としては、透明プラスチックシートに厚さ16μmの二軸延伸ポリエチレンテレフタレート(PET)を、離型樹脂層に厚さ10μmのポリエチレン(PE)を、感熱接着剤層に厚さ8μmのエチレン酢酸ビニル共重合体(EVA)を用いて積層し、<EVA8μm/PE10μm/PET16μm/EVA8μm>なる構成が挙げられる。   The pseudo adhesive sheet 105 is obtained by laminating a release resin layer and a heat-sensitive adhesive layer using a transparent plastic sheet as a base material. As a laminating method, a resin may be laminated on a transparent plastic sheet by an extrusion method, or a resin may be laminated by an emulsion type, a solution type, or hot melt by a coating method. As a specific example of such a pseudo-adhesive sheet, biaxially stretched polyethylene terephthalate (PET) having a thickness of 16 μm is formed on a transparent plastic sheet, polyethylene (PE) having a thickness of 10 μm is formed on a release resin layer, and a heat-sensitive adhesive layer is formed. A configuration in which an ethylene vinyl acetate copolymer (EVA) having a thickness of 8 μm is stacked and <EVA 8 μm / PE 10 μm / PET 16 μm / EVA 8 μm> is given.
