Problems solved by technology

However, the above method can only prevent unscrupulous persons from unpacking from the edge seal or other positions with RFID tags. If unscrupulous persons unseal any other places where RFID tags are not installed, the RFID tags will not be damaged, so The RFID reader cannot recognize that the document bag has been unsealed, so the above-mentioned method cannot realize the all-round anti-tampering of the document bag without dead ends

Embodiment 1

[0024] Such as Figure 4 As shown, the RFID tag 100 includes an antenna loop composed of a metal foil 101 with a line width of 1-5 mm and an RFID chip 102 . The metal foil 101 is connected to both ends of the RFID chip 102 to form an antenna loop, and the antenna loop is clamped between two pieces of PET film and fixed. In the antenna loop, the line spacing between adjacent metal foils 101 is generally 1-5 mm.

[0025] During the manufacturing process, the outer contour size of the RFID tag 100 is the size of the entire bag wall of the file bag. The RFID tag 100 can be embedded in the bag wall in advance, and then the bag wall is assembled into the file bag through processing technology. The line width of the metal foil 101 and the line spacing of adjacent metal foils 101 are preferably equal, so that when forming the folded edge on each side, the metal foil inside the folded edge can be aligned with the metal foil of the bag wall. Figure 5 It is a schematic diagram of the ...

Embodiment 2

[0027] Figure 6 It is another RFID tag design solution. The RFID tag 100 includes an antenna loop formed by an RFID chip 102 and a metal foil 101 connected to the RFID chip 102 . The RFID tag is designed in the shape of the sidewall of the file bag before it is formed, and can be bent along the dotted line 1, the dotted line 2, the dotted line 3 and the dotted line 4 into the shape of the file bag. Figure 7 It is a schematic diagram of the combination of RFID tags and file bags. Such as Figure 7 As shown, there is an antenna loop at a position not far from the final document bag. When criminals cut any part of the document bag to steal documents, the antenna loop will be cut off, and any part of the antenna loop will be broken. If it is opened, it will cause the RFID chip to be unrecognizable, so as to realize the function of anti-tampering.

[0028] In addition, in order to strengthen the safety of the opening of the file bag (such as the upper folded edge), the edge of...

Abstract

The invention relates to anti-opening devices, in particular to an anti-opening device for a file pocket. According to the file pocket anti-opening device, a radio frequency identification devices (RFID) tag is clamped and held in a pocket wall of the file pocket and is fixed, the RFID tag comprises an antenna return circuit which is formed by an RFID chip and line-shaped metal foil which is connected at two ends of the RFID chip, if any one position of the antenna return circuit breaks, the RFID chip cannot be identified, the size of an outer contour of the RFID tag is equal to or a little less than the size of the whole packaging of the file pocket, and the RFID tag is laid on the inner surface or an inner interlayer of the pocket wall of the whole file pocket so that if any one position of the file pocket is dismounted, the antenna return circuit can be caused to break. The file pocket anti-opening device is applied to anti-opening performance which is all-round and free of a dead angle of the whole file pocket.

Description

technical field [0001] The invention relates to an anti-disassembly device, in particular to an anti-disassembly device for a file bag. Background technique [0002] With the advancement of science and technology, people have higher and higher requirements for the safety protection of documents, document bags and packaging bags, and the existing packaging bags, such as cash bags, express packaging, court evidence bags, and examination papers, Confidential documents, controlled drugs and other envelopes (in this article, the above-mentioned envelopes are collectively referred to as document bags) have poor confidentiality. Unscrupulous people can easily unpack the envelopes and restore the same packaging as the unopened ones, resulting in Confusion and misidentification of recipients lead to the outflow of important documents and data without knowing it, causing major risks to business operations, technology research and development, and social security. [0003] Existing fi...
