Description

  The present invention relates to a concealment label, particularly a concealment label that can be suitably used to conceal confidential information such as personal information written on a postcard or the like.

There are postal items that require concealment of confidential information such as personal information entered on postcards, such as dividend transfer specification forms, voting rights exercise forms, automatic account transfer application forms, and content confirmation postcards with contractors.
This type of mail is handled as follows, for example. First, a sender of a company or the like sends a postcard and a concealment label in an envelope or mails them, or attaches a concealment label to a peeled back and forth postcard and mails it to the recipient.
Recipient fills in the postcard with confidential information such as account number, address, name, telephone number, etc., and a concealment label is attached to the surface of the entered confidential information so that the confidential information is not leaked to the outside. Return the postcard to the sender.
The sender who has received the returned postcard with the concealment label peels off the concealment label affixed to the postcard, thereby confirming each secret information entered on the postcard and performing paperwork such as data input.

As a concealment label used for the above purpose, there is a concealing cover sheet, a transparent protective film pseudo-bonded to the cover sheet, and an adhesive layer provided on the opposite side of the protective film cover sheet. The thing of the structure provided is known (for example, patent document 1).
The concealment label having such a configuration is attached to the postcard by the adhesive layer. And since it can peel between a copper sheet and a protective film, the sender can peel only a cover sheet and can see through confidential information through a protective film.
This peeled cover sheet can no longer be reapplied to the protective film. Therefore, in the unlikely event that a third party peels off and acquires confidential information before returning to the sender's hand, the fact becomes clear, and it is easy to prevent leakage of confidential information to a third party. There is an advantage.

However, the concealment label configured as in Patent Document 1 is a manual work of lifting the corners of the cover sheet with nails and picking the corners of the lifted cover sheet by hand when peeling the cover sheet, When the amount of the concealment label to be peeled off is large, the burden on the operator is great. For this reason, a method has been proposed in which a peeling tape is applied from above and the peeling tape is pulled to pull the tape (for example, Patent Document 2).
Further, the concealment label configured as in Patent Document 1 is almost impossible even if the sender wants to perform stamping or writing when performing paperwork such as data entry because the protective film remains on the postcard. Met. For this reason, it has been proposed to use a polyethylene terephthalate nonwoven fabric as a protective film to impart aptitudes such as stamping and writing on the protective film (for example, Patent Document 3).
Japanese Utility Model Publication No. 1-67075 JP 2003-182267 A Registered Utility Model No. 30002758

However, in the peeling method as in Patent Document 2, it is necessary to perform peeling printing that can be peeled off from the peeling tape on the postcard side, and secret information or the like cannot be written in the printed portion. Therefore, the range that can be used as an entry field is limited.
Moreover, it is necessary to affix a peeling tape correctly on the part to which the printing for peeling was given, and especially in the case of manual work, position alignment was not easy. Furthermore, when the amount of the concealment label to be peeled off is large, there is a problem that a large amount of peeling tape must be used and discarded.

  Moreover, in the concealment label using a polyethylene terephthalate nonwoven fabric as a protective film like patent document 3, the writability after peeling etc. are provided to some extent. However, since the polyethylene terephthalate nonwoven fabric is inferior in smoothness to paper and porous, the written material is likely to bleed. Even if a clear character can be written immediately after writing, for example, bleeding gradually progresses until the ink of the water-based pen dries. Therefore, compared with the case of writing on the paper body, the writing ability and the stamping ability were not sufficient.

This invention is made | formed in view of the said situation, Comprising: It is a subject to provide the concealment label which cannot be reattached after peeling, is excellent in confidentiality retention, and is easy to peel off.
It is another object of the present invention to provide a concealment label that cannot be reapplied after peeling, has excellent confidentiality, and can be written or stamped after peeling.

According to the invention of [7], a peripheral edge deletion portion that becomes a peeling opening (knob opening) is provided from each of two opposing sides of the laminated sheet. Therefore, regardless of the direction in which the concealment label is attached to a postcard or the like, there is an effect of facilitating the peeling operation.
Moreover, since the marginal deletion part does not exist in the corner part, there is an effect that it is difficult to peel off carelessly during mailing.
Further, the release sheet is cut at an intermediate position between the first side and the second side, and can be peeled off from the cutting position. Therefore, when peeling a peeling sheet, there exists an effect that the transparent film etc. of a periphery deletion part periphery are not impaired.
Further, the presence of the peripheral edge deletion portion can provide a portion where the postcard or the like is exposed as it is after the concealing base material is peeled off. Therefore, the portion retains the writing ability and the stamping ability originally possessed by the postcard and the like, and has an effect of facilitating writing and stamping.
