BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminated adhesive sheet, and particularly, the laminated surfaces can be peeled from each other, and
The present invention relates to a laminated adhesive sheet that is adhered via an adhesive structure that does not normally adhere after peeling. Here, "not normally adhered" means not adhered unless a special condition such as application of a new adhesive, application of a certain pressure or more, heating, or the like is applied.

[0002]

2. Description of the Related Art A conventional adhesive sheet of this type is
In general, appropriate transmission information is displayed as necessary on at least a pair of overlapping surfaces that are peelable and are bonded so that they do not normally adhere after peeling, and the desired address is displayed in the concealed state. The addressee, who has transmitted and received the information to the person, visually recognizes the transmitted information by peeling off the overlapping surface and exposing the displayed transmitted information.
Since the overlapping surface once peeled does not normally adhere, it is not possible to closely adhere it, but also due to the difference in the thickness of the sheets forming the overlapping surface or the difference in rigidity, one of them separates in a warped state. It will be done.

[0003]

Therefore, in the prior art, since it is warped and bulky, it is not easy to store it, and since the transmitted information cannot be hidden again, it may be seen by others. . It is an object of the present invention to provide a laminated adhesive sheet that solves this inconvenience.

[0004]

In order to achieve this object, the present invention provides that at least a pair of superposed surfaces are adhered to each other via an adhesive structure which is separable and does not normally adhere after the separation. A locking portion for locking the other edge after peeling is provided on one side of the overlapping surface.

[0005]

[Function] By locking the other end edge after peeling to the locking portion provided on one of the overlapping surfaces, it is possible to prevent separation in the warped state, and to prevent the transmitted information from overlapping on the overlapping surface. If it is displayed, it can be hidden again to prevent it from being seen by others.
