Tamper detection sheet

Abstract

The present article is an tamper-detection sheet that is attached to a packaging material having a storage compartment for storing, for example, tablets, and detects the tampering of the storage compartment. The present article includes a conductive portion provided on the front surface and a break line that penetrates from the front to the back surface. When in use, the back surface of the present article is attached to the packaging material, as shown in the reference oblique view showing the state of use. After attachment, a portion of the conductive portion of the present article passes over the storage compartment of the packaging material, as shown in the reference plan view showing the state of use. When the contained item is pushed out of the packaging material, the present article is easily broken by the break line, and the conductive portion is broken. The breakage of the conductive portion makes it possible to detect the tampering of the storage compartment by an external tamper-detection device, etc. Furthermore, as shown in the reference oblique view and reference front view showing the state of use, a transparent or translucent protective layer may be provided on the front surface of the present article to cover the surface other than the terminal portion of the conductive portion.
