Description

[Detailed Description of the Invention] The present invention displays information that should be hidden and should not be known to others (hereinafter referred to as hidden information), such as deposit balances, loan repayment balances, various PIN numbers, etc. The present invention relates to a concealment carrying member in which concealment information is covered and concealed by removably adhering a concealment sheet to a concealment information display card, and a method for producing the same.

Note that the term "card" in this specification refers to not only a normal card but also any sheet-like member capable of displaying hidden information such as a postcard.

■ Conventional concealed information display members of this type do not provide any special adhesive means on the concealed information display card as a means for removably adhering the concealed information display card and the concealment sheet. This is done by adjusting the adhesive strength of the adhesive provided on the back surface of the concealing sheet.

For this reason, in the past, if the adhesive provided on the concealing sheet was too strong, when it was peeled off from the concealed information display card, the concealed information display side of the card would also be peeled off. If the adhesive strength is too weak, the concealment sheet will peel off from the card during handling, making it impossible to perform its function as a concealed information carrying member. Therefore, there was a problem in that it was extremely difficult to adjust the adhesive strength of the adhesive.

An object of the present invention is to provide a concealed information carrying member and a method for producing the same that eliminates such inconveniences.

In order to achieve the above-mentioned purpose of suppressing the buds, the concealed information holding member of the present invention includes a concealed information display card on which information to be concealed is displayed;
The above-mentioned concealing sheets for covering and concealing the information to be concealed are overlapped with each other, and a sheet provided on a predetermined part of one of these overlapping surfaces is normally not adhered, but can be adhered under certain adhesive conditions. A strong adhesive layer with a strong adhesive force is provided on the other overlapping surface at least in a portion corresponding to the strong adhesive layer, and a strong adhesive layer has a weak adhesive force and provides adhesive conditions to the strong adhesive layer. It is activated by the obtained weak adhesive layer, that is, it is brought into a bondable state, and the part corresponding to the weak adhesive layer is more easily peeled and adhered than the part corresponding to the strong adhesive layer.

Further, the method for creating a concealed information possession member of the present invention includes an information display surface to be concealed of a concealed information display card on which information to be concealed is displayed, and the information to be concealed to cover and conceal the information to be concealed. A strong adhesive layer with a strong adhesive force that does not normally adhere to the overlapping surface of the concealing sheet that is overlaid on the information display surface, but becomes adhesive under certain adhesive conditions. , a weak adhesive having weak adhesive force and capable of imparting adhesive conditions to the strong adhesive layer is provided on at least the other side of each surface corresponding to the strong adhesive layer, and the hidden information display is By overlapping the information display surface of the card to be concealed and the overlapping surface of the concealment sheet, and activating the strong adhesive layer with the weak adhesive, that is, making it possible to bond, the concealed information display card and the concealing sheet are bonded to each other more easily in areas corresponding to the weak adhesive than in areas corresponding to the strong adhesive layer.

Even if the adhesive strength of the adhesive on one of the stacked surfaces of the concealment information display card or the concealment sheet is set to be weak enough to be peelable, the strong adhesive on the other surface Since the concealing sheet and the concealing information display card are firmly bonded in the layer, there is no fear that the concealing sheet will peel off from the concealing information display card during handling, and the A concealment sheet can be extracted from the concealment information display card. Therefore, it is easy to adjust the adhesive force of the adhesive when creating the hidden information carrying member.
