Description

  The present invention relates to a concealed postcard that can reliably maintain the confidentiality of the contents written in the postcard entry field, and in particular, the information entered on the postcard before the mailed postcard is delivered to the recipient. This is related to a concealment postcard that is easy to open by the recipient while preventing the person from seeing it.

  Conventionally, as a concealed postcard that prevents others from seeing the notification information, a postcard body piece of the same size and a concealment paper piece are joined so as to be foldable, and there is an entry field for entering predetermined items on the inner surface of the postcard body piece. There is known a concealing postcard having a configuration in which a re-peeling adhesive is applied to the inner surface of a concealing paper piece, and a separating paper is stuck on the surface (see, for example, Patent Document 1).

  However, in the above concealment type postcard, for example, the customer takes back the concealment type postcard from a financial institution etc. Remove the release paper attached to the piece of paper, and attach the cover paper piece as a single postcard with the re-peeling adhesive applied to the cover paper piece to cover the entry field on the inner surface of the postcard body piece In case of posting, the re-peeling adhesive applied to the concealment paper piece has re-adhesive properties, so that a third party can peel off the concealment paper piece during the delivery of the postcard and see the written contents. When the concealment paper piece is adhered again after seeing the contents of entry, it is not known that it was seen by a third party, and thus there is a disadvantage that the confidentiality is not completely maintained.

Therefore, a postcard paper piece and a concealment paper piece of the same size are connected so as to be foldable via a crease line, and an entry field for entering a predetermined item is provided on the inner surface of the postcard paper piece, and the cover paper piece has an end facing the crease line. A perforation is formed at a position closer to the inside by a predetermined width from the edge, and a weak pressure-sensitive adhesive layer is formed on the inner surface of the masking paper piece to be peelably adhered to the region between the crease line and the perforation. Concealment consisting of a structure in which an adhesive layer that is adhered to the perforation is formed in an area between the edge opposite to the line of sight and the perforation, and a release paper is attached to cover the weak adhesive layer and the adhesive layer. Postcards have been proposed (see, for example, Patent Document 2). By sticking the concealment paper so as to cover the entry field of the postcard paper piece with the concealment postcard disclosed in Patent Document 2, the description content described in the entry field can be concealed and the description content is concealed. Even when handling during delivery, there is no risk of the cover paper pieces peeling off from the postcard paper pieces. Although the confidentiality of the contents can be reliably maintained, there is a problem with the openability of the cover-up postcard. In other words, when using a postal sorting device, a concealed postcard having a perforation with good openability is folded when passing through a roller or belt provided in the postal sorting device, and the uncut portion of the perforation is broken. There is a problem that the concealment paper piece is partially peeled off from the postcard body piece, and a perforation that does not break the uncut portion is used even if the postal sorting device is used. The current situation is that it is harder to open the cover postcard than the perforation.
