Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to packaging members such as wrapping paper.

[Prior Art] Various methods have been proposed to prevent shoplifting of products that directly affect profits at retail stores. There is a method of incorporating it into a card and inserting this card into the above product. Then, when paying for the product, the user removes the card. Note that the above detection circuit is
It consists of a coil and a capacitor.

[Problems to be solved by the invention] In the conventional method described above, there is a problem in that it is difficult to reliably prevent shoplifting of products because the cards can be easily removed from the products in the store. .

[Means for Solving the Problems] In the present invention, a detection circuit for a bagler system formed of a conductive thin film or a metal sheet is installed in a part of a packaging member such as a wrapping paper.

[Function] In the present invention, a detection circuit for a bagler system made of a conductive thin film or a metal sheet is installed in a part of a packaging material such as wrapping paper, so that it is impossible to remove the packaging material inside a store. Since it is natural, it is possible to reliably prevent shoplifting of products.

[Example] FIG. 1 is a developed view of a wrapping paper showing an example of the present invention.

A detection circuit 20 is installed on the back side of the wrapping paper 10. The detection circuit 20 is composed of an antenna section 21 and a resonant circuit section 22, which are composed of a conductive thin film or a metal sheet. The conductive thin film is attached to the wrapping paper 10 by vapor deposition, and the metal sheet is adhered to the wrapping paper 10 with an adhesive or the like.

The wrapping paper 10 is made of a material that makes a rustling sound when folded, such as cellophane paper.

FIG. 2 shows a product 30 in the wrapping paper 10 of the above embodiment.
FIG. 2 is a perspective view showing a wrapped state.

The packaging is done so that the detection circuit 20 does not overlap the folds of the wrapping paper 10. This is because if the detection circuit 20 hits the crease, the frequency characteristics change and shoplifting may not be detected.

FIG. 3 is a diagram showing an example of a buckler system using the above embodiment.

The transmitter 41 is for generating an electric field, magnetic field, or electromagnetic field of a predetermined frequency, and the transmitting coil 42 is for radiating the electric field etc. generated by the transmitter 41. The receiving coil 43 is the transmitting coil 4
2, and a person carrying the product 30 can pass between the coil 42 and the transmitting coil 42. The receiver 44 is a circuit that receives the signal received by the receiving coil 44, and the determining means 45 is a circuit that receives the signal received by the receiving coil 44.
The alarm device 46 is a means for detecting that the detection circuit 20 is installed in the wrapping paper 10 of No.

Next, the operation of the above embodiment will be explained.

First, although it depends on the frequency of the radiation signal generated from the transmitter 41, for example, if the frequency of the radiation signal is 900MHz, the length of the detection circuit 20 installed on the wrapping paper 10 may be about 5 cm. .

The transmitter coil 42 and the receiver coil 43 are provided at a checkpoint (a space between the cash register (payment place) and the exit in the store) and are covered by a wall or the like. When the shoplifter carries the product 30 and passes the above checkpoint, the transmitting coil 42
Since the radiation signal radiated from the wrapping paper 10 is absorbed by the detection circuit 20 installed in the wrapping paper 10, the level of the radiation signal received by the receiver 44 is reduced. Therefore, the means 4 for determining whether this level has decreased
5 makes the determination, and the alarm device 46 issues an alarm.

Note that since the detection circuit 20 absorbs the radiation signal radiated by the transmitting coil 42 and then re-radiates it, the re-radiated signal may have an in-phase relationship with the radiation signal or an inverse relationship depending on the relative positional relationship between the transmitting coil 42 and the detection circuit 20. There is a correlation between the signals, which causes the level of the received signal at the receiver 44 to change in height. When the determining means 45 determines that the amount of change in height is greater than or equal to a predetermined value, the alarm device 46 issues an alarm.

Furthermore, if the shoplifter does not know that the detection circuit 20 is installed in a part of the wrapping paper 10, he or she will definitely be warned when passing the above-mentioned checkpoint. Even if the shoplifter knows that the detection circuit 20 is installed in a part of the wrapping paper 10, it would be unnatural for the shoplifter to remove the wrapping paper 10 inside the store.
cannot be removed and the product 30 cannot be taken out of the store. Therefore, shoplifting of products can be reliably prevented.

Since the wrapping paper 10 is made of cellophane paper or the like, when the wrapping paper 10 is unfolded or folded,
This is more effective in preventing shoplifting since a rustling sound is generated and people are reluctant to remove the wrapping paper 10.

On the other hand, when paying for the product 30 at the cash register of a store, the store clerk places the product 30 in a high-frequency magnetic field (frequency of several MHz or less) generated by a high-voltage, high-frequency current generating means (not shown). When you insert
A portion of the conductive portion constituting the detection circuit 20 is burned out. That is, the conductive thin film or metal sheet constituting the detection circuit 20 is heated and evaporated due to eddy current loss caused by the high frequency current. Detection circuit 20
Since the wire diameter of the conductive part that makes up the
The above heating and evaporation are performed instantaneously. If even a part of the conductive part that makes up the detection circuit 20 is burnt out, the frequency characteristics of the detection circuit 20 will change.
Thereafter, even if the wrapping paper 10 passes the above-mentioned check point, the alarm 46 does not operate.

Therefore, there is no need to remove the wrapping paper 10 each time the store receives payment for the product.
The work is easy and shoplifting can be effectively prevented.

The wrapping paper 10 may be made of a material that does not make a rustling sound when folded, such as vinyl. Further, the detection circuit 20 may be installed on the front side of the wrapping paper 10. As product 30,
Each store has its main products, such as records, audio/video tapes, etc., and any product other than metal is acceptable.

FIG. 4 is a perspective view showing another embodiment of the present invention.

In this embodiment, a packaging bag 10 is used instead of the wrapping paper 10.
A is used, and a detection circuit 20 is provided on the back side (inside) of the packaging bag 10a. Even when this packaging bag 10a is used, shoplifting can be reliably prevented in the same way as described above.

Note that the product 30a is similar to the product 30. The detection circuit 20 may be installed on the bottom or surface of the packaging bag 10a.

FIG. 5 is a perspective view showing another embodiment of the present invention.

In this embodiment, a packaging bag 10b is used instead of the packaging bag 10a. The packaging bag 10b is
The packaging bag 10 is a bag made of a transparent material with an entrance 11 sealed by thermocompression or adhesive.
A detection circuit 20 is provided on the back side (inside) of b. Even when this packaging bag 10b is used, shoplifting can be reliably prevented in the same manner as described above.

Note that the product 30b is similar to the product 30. The detection circuit 20 may be installed on the bottom or surface of the packaging bag 10a.

Furthermore, instead of the packaging bags 10a, 10b, packaging boxes (not shown) are used to hold the products 30, 30a, 30.
b may be packaged. That is, the detection circuit 20 may be installed in a packaging member for packaging a product, such as the wrapping paper 10, packaging bags 10a, 10b, packaging box, etc.

Further, although the detection circuit 20 has a resonant circuit section 22 that functions as a capacitor, this may be omitted and the detection circuit 20 may be configured only with a bar-shaped conductive pattern.

Incidentally, by incorporating diodes into the coils 42 and 43, changes in frequency characteristics may be made noticeable during re-radiation.

Moreover, the materials of the wrapping paper 10 and the packaging bags 10a and 10b may be transparent, translucent, or opaque.

[Effect of the invention] According to the invention, it is possible to reliably prevent shoplifting of products.
