About these concealment postcards, for example, a folding line for dividing the first base material portion and the second base material portion is provided in the approximate center of the sheet base material, and is written in the first base material portion. A mail order form having a structure of a concealment label in which a column is provided and a release layer, a transparent adhesive layer, a transparent base material layer, a transparent adhesive layer, and a release paper are sequentially laminated on the second base material part is known (For example, refer to Patent Document 1).

  However, since the above mail order form (postcard) is not re-adhesive after opening the transparent adhesive layer, the postcard sent to the recipient is sent to the third party before the mailed postcard is delivered to the recipient. If it is opened and stolen, the fact can be understood, but there is a problem that it is opened accidentally during mailing. In particular, a configuration in which the ends of the first base material portion and the second base material portion that are bonded together so that the recipient can easily open the seal when opening is easily opened by mistake.

  Also, a postcard paper piece and a concealing paper piece of the same size are connected so as to be foldable, and an entry field for entering predetermined items is provided on the inner surface of the postcard paper piece, with an adhesive having a predetermined width along the edge facing the crease line. A release paper is laminated so as to cover the adhesive layer, a weak pressure-sensitive adhesive layer is formed on the inner surface of the masking paper piece, a release paper is adhered to cover the weak pressure-sensitive adhesive layer, and the folding line of the masking paper piece There is also disclosed a concealing postcard having a structure in which perforations are formed at positions that are inward by the width of the adhesive layer along opposite edges (for example, see Patent Document 2).

The above-mentioned masking postcard has a central part between the masking paper piece and the postcard paper piece that is peelably bonded by a weak adhesive layer, and an adhesive layer between the edge facing the crease line of the masking paper piece and the perforation. The postcard is not accidentally peeled off when the postcard is handled while it is being mailed. It can be peeled off and the contents entered in the entry field can be viewed. However, after opening, the weak adhesive layer can be re-adhered, and when a third party peels off the concealed paper piece to see the contents while mailing, and then re-adheres the concealed paper piece, the recipient opens it. There is a problem of not being aware of what has been done.
