Description

  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.

  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).

However, the concealment postcards disclosed in Patent Documents 1 and 2 described above 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 by 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 machine processes such as a mail sorting machine, the exposed adhesive surface sticks to other postal items and causes troubles. There is a problem of trouble such as double feeding.

Are directly bonded to each other.

  According to a fifth aspect of the present invention, in the invention according to the third or fourth aspect, the release agent layer is colored to improve the concealability.

  Since the concealment postcard of the present invention is smaller in size than the postcard body piece, the postcard body piece on which information is entered is folded in half at the crease line provided in the approximate center and concealed with the concealment paper piece. Even if bending or the like occurs, the adhesive provided on the concealment paper piece is not exposed, so troubles such as double feeding even if it is processed by a postal sorting machine at a post office, for example. There is an effect that can be prevented.

  In addition, since the size of the concealment paper piece is smaller than that of the postcard body piece, the recipient has an effect that opening is easy when opening. In addition, since a part of the lower surface of the transparent sheet and a part of the masking paper piece are directly bonded to the one side edge portion on the lower surface side of the transparent sheet, the transparent sheet is erroneously peeled off from the base paper. Can be prevented.

  Further, by coloring the release agent layer, the concealing property of the concealment paper piece is increased, the confidentiality can be improved, the thickness of the concealment paper piece can be reduced, and the cost can be reduced and the volume of waste can be reduced. .
