Anti-counterfeit bottle structure

The present invention relates to an anti-counterfeit bottle structure, and more particularly to an anti-counterfeit bottle structure having an electronic tag.

At present, commercially available bottled products, commonly used anti-counterfeiting technologies include watermarks, anti-counterfeiting inks, anti-counterfeit laser labels, bar codes, and telephone code inquiries. Most of these anti-counterfeiting technologies are designed on the bottle caps of bottled goods to help consumers identify their authenticity at the time of purchase, to determine whether the cap has been opened or reloaded. However, these anti-counterfeit labels have the following disadvantages: (1) the technical threshold is not high and easy to be copied; (2) the effective anti-counterfeiting life is short, and if a new anti-counterfeit label is listed, it is generally in the market for three months to six months. There will be a large number of imitations; (3) no anti-fouling, once the label is defaced, it can no longer be identified; (4) the telephone code query needs to be paid, and there are not many consumers actually using it.

Therefore, the market is still full of all kinds of counterfeit bottled goods, preventing accidental prevention, causing serious losses to the industry, relatively affecting the performance of goods and consumers' willingness to purchase, and needs to be improved.

The invention relates to an anti-counterfeiting bottle structure for improving the anti-counterfeiting effect, and using the liquid substance contained therein to change the radiation field type of the radiator, so that the radiation field type has a strong antenna above or below the bottle mouth. Gain, for better reading characteristics in the direction of the bottle mouth measurement.

According to an aspect of the invention, an anti-counterfeit bottle structure is provided, comprising a bottle body, a liquid substance, and an electronic tag. The bottle body has a bottle body. The bottle has a bottle mouth. The liquid substance is placed in the bottle body and the liquid The substance has a dielectric constant. The electronic tag is placed on the bottle. The electronic tag has a radiator whose radiation field type has a stronger antenna gain above or below the mouth of the bottle relative to a plane perpendicular to the bottle body, depending on the dielectric constant of the liquid substance.

In order to more clearly understand the above and other aspects of the present invention, the following detailed description of the embodiments and the accompanying drawings

The anti-counterfeiting bottle structure of the embodiment uses an electronic tag of Radio Frequency Identification (RFID) to achieve anti-counterfeiting effect. The operating frequency of the electronic tag can be 860~960MHz, and each electronic tag has a world unique code. At the same time, the chip has a certain memory space for reading and writing data, which can be encrypted, non-replicable, long service life, anti-fouling and long distance reading data. In addition, the electronic tag wafer is packaged on a flexible substrate and can be flexed, so that it can be arbitrarily changed depending on the shape of the bottled product.

In one embodiment, the electronic tag is attached to the bottled product containing the liquid substance 116 to provide the anti-counterfeiting effect of the bottled product. Please refer to FIGS. 1A and 1B , wherein FIG. 1A is a schematic diagram of an anti-counterfeit bottle structure according to an embodiment, and FIG. 1B is a schematic diagram of a radio frequency module for detecting an anti-counterfeit bottle structure according to an embodiment. . The anti-counterfeit bottle structure 100 includes a bottle body 110, a liquid substance 116, and an electronic tag 120. The bottle body 110 has a cap 114 and a bottle body 112. The bottle body 112 has a bottle opening 112a, and the bottle cap 114 is used to seal the bottle opening 112a. The liquid substance 116 is contained within the bottle body 112, and the liquid substance 116 has a dielectric constant. The electronic tag 120 is disposed on the bottle body 112. The electronic tag 120 has a radiator 122 having a radiation field type according to a dielectric constant of the liquid substance 116 above or below the bottle opening 112a with respect to a plane perpendicular to the bottle body 112 (Z axis) (XY plane) ) has a strong antenna gain. In an embodiment, the radiation pattern of the radiator 122 is more likely to have a stronger antenna gain on a plane parallel to the body 112 (Z-axis) (XZ plane or YZ plane) to form an omnidirectional radiation field. type. When the anti-counterfeit bottle structure 100 is placed in the detecting device, the radio frequency detecting module 150 located above the bottle mouth 112a detects the signal sent by the electronic tag 120 to identify the authenticity.

In FIG. 1B, the radio frequency detection module 150 has, for example, a circularly polarized antenna for transmitting an ultra-high frequency (UHF) segment of the radio frequency signal. When the bottle body 110 is placed in the working range of the circularly polarized antenna, the electronic tag 120 on the bottle body 112 receives the RF energy and activates the built-in chip (not shown). The chip transmits information such as its own identification code. The radiator 122 is sent outward because the radiation pattern of the radiator 122 has a strong antenna gain above or below the bottle opening 112a or on a plane parallel to the bottle body (Z-axis) (XZ plane or YZ plane) An omnidirectional radiation field type, such as the radiation field type shown in Figure 2 (converted label reading distance), the effective measurement range above or below the bottle mouth can be greatly increased. After the radio frequency module 150 receives the signal transmitted from the electronic tag 120, the received signal is demodulated and decoded, and the legality of the electronic tag 120 is determined according to a logical operation. Therefore, the anti-counterfeit bottle structure 100 of the embodiment can achieve the anti-counterfeiting effect. In addition, the battery does not need a battery in the electronic tag 120, but uses the beam power supply technology to convert the received RF energy into a DC power source to supply power to the circuit in the electronic tag 120.

Figures 3A and 3B are schematic views showing the radiation pattern of the electronic tag in the X-Z plane and the X-Y plane, respectively. Referring to FIG. 3A, in an embodiment, when the radiator 122 of the electronic tag 120 is attached to the bottle body 112 parallel to the ZY plane, and there is no liquid substance 116 (air only) in the bottle body 112, the experiment is performed. As a result, it has been found that the radiation pattern of the electronic tag 120 has an omnidirectional radiation pattern on the XY plane and two weaker zero points on the XZ plane, which will cause the electronic tag 120 to be It can be read stably on the XY plane, but it cannot be read above or below the Z axis. In addition, referring to FIG. 3B, in an embodiment, when the radiator 122 of the electronic tag 120 is attached to the bottle body 112 parallel to the ZY plane, and the liquid body 116 is contained in the bottle body 112, it is found through experimental results. Using the dielectric property of the liquid substance 116, the radiation pattern of the electronic tag 120 has an omnidirectional radiation pattern on the XZ plane, and the zero point originally located on the XZ plane is converted to the XY plane, so that the electronic tag 120 Features that could not be read above or below the Z axis become readable features.

From the above comparison, it can be found that since the dielectric constant of the liquid substance 116 is much larger than the dielectric constant of the air, when the electronic tag 120 is attached to the bottle body 110 containing the liquid substance 116, the electronic tag 120 The radiation pattern is changed by the dielectric constant of the liquid substance 116. In one embodiment, the antenna impedance can be adjusted based on the range of dielectric constants of the liquid material 116 such that the electronic tag 120 can be applied to various bottled articles containing the liquid material 116, such as alcohol, juice, cola. The soda body, the mineral water, and the like, and the material of the bottle body 110 is, for example, glass or plastic, but there is no limitation thereto.

For example, in FIG. 4B, the electronic tag 120 is parallel to the Y-Z plane and oriented in the +X-axis direction, and is symmetrical to the X-axis to the surface of the bottle body 112. In the present embodiment, the dimension L is the width of the bottle directly behind the electronic tag 120. It can also be said that the dimension L is the width of the bottle body 112 on the X-axis.
