Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-theft seal, and more particularly to an anti-theft seal capable of detecting shoplifting theft of a product.

[0002]

2. Description of the Related Art Shoplifting and theft damage in department stores, supermarkets, bookstores, etc. is large, and it is said that there are many cases in which a shopkeeper loses money due to shoplifting damage. Because of this, a small transmitter is attached to expensive items such as clothes, and the transmitter is removed at the cash register when passing through the cash register, and if you go outside without passing through the cash register, the radio wave of the transmitter will enter and exit the store A method has been taken to prevent theft by detection by a sensor.

[0003]

Since the transmitter is bulky even if it is small, it cannot be attached to a small product such as a CD or a book.
There was a drawback in that a large number of transmitters could not be kept at all times because they were expensive. The present invention, in view of those circumstances,
The invention has been developed with the aim of providing an anti-theft seal that can be easily attached to small products without being known by customers.

[0004]

The present invention has the following technical means in order to solve the above-mentioned problems and achieve the object.

That is, as in a seal attached to a product, a radio wave transmitting layer is formed on the surface of a base material, and the anti-theft seal is configured to transmit radio waves to a corresponding specific sensor. It is configured. An adhesive layer can be formed on the lower surface of the substrate.

[0006] The base material is paper, cloth, resin sheet,
It can be arbitrarily selected from metal plates.

[0007] The radio wave transmitting layer can be printed on a base material.

[0008] The radio wave transmission layer is formed in a sheet shape,
Can be adhered to a substrate.

The radio wave transmission layer can be selected from solid paint, characters, symbols, and figures.

[0010] The radio wave transmitting layer may include a magnetic material.

[0011] The radio wave transmitting layer may include a material that produces a Seebeck effect.

[0012] The radio wave transmitting layer may include a conductive paint having a high resistivity.

The radio wave transmitting layer may include a ferroelectric.

[0014] The radio wave transmitting layer may include an ultrasonic resonance material.

[0015]

The present invention configured as described above has the following operation.

The anti-theft seal can be attached to or affixed to a small product.

When the user leaves the store without removing the anti-theft seal from the product, the sensor detects the radio waves transmitted from the radio wave transmission layer of the seal, thereby preventing theft.

[0018]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of the anti-theft seal. In the figure, the anti-theft seal 1 has a radio wave transmitting layer 3 formed on the surface of a base material 2, an adhesive layer 4 formed on the lower surface of the base material 2, and a release paper 5 adhered under the adhesive layer 4. When used like a hanging tag, it is used without forming the adhesive layer 4.

The base material 2 is arbitrarily selected from a thin flexible material such as paper, resin film, cloth, or metal plate. It is cut into a large area at the time of manufacture, and to a size necessary for completing the formation of the radio wave transmission layer and the like.

The adhesive layer 4 can be made of a material used for a general adhesive tape, a pressure-sensitive adhesive, a glue, or the like.

The radio wave transmitting layer 2 is a layer containing a substance capable of transmitting a radio wave (electromagnetic wave). The transmission here includes self-transmission and reflection transmission.

The anti-theft seal 1 having the above configuration is attached to the product 6. That is, if the adhesive layer 4 is provided on the lower surface of the base material 2, the release paper 5 is peeled off and adhered to the product.
The material without the adhesive layer 4 is hung or fixed on the product with a thread, a string or other means. When the product 6 passes through the cash register, the anti-theft seal 1 is detached at the cash register and the product is delivered to the customer.

As shown in FIG. 2, sensors 7 and 8 are arranged at the entrance and exit of the store at the left and right or up and down of the passage. Since the anti-theft seal 1 is still attached to the product 6 that has not passed through the cash register, when passing between the sensors 7 and 8, radio waves transmitted from the radio wave transmission layer 2 of the anti-theft seal 1 are transmitted to the sensors 7 and 8. 8, an alarm (not shown) is activated to prevent theft. The sensor may include only a receiving circuit or both a transmitting circuit and a receiving circuit, or may emit infrared rays or ultraviolet rays. Further, the sensor corresponding to only the radio wave transmission layer 2 is selected.

A specific example of the radio wave transmitting layer 3 will be described below. For example, ferroelectric barium titanate porcelain powder is kneaded with a synthetic resin (including ink) and printed on the surface of the substrate 2. The sensors 7 and 8 transmit electromagnetic waves as magnetic sensors. When the anti-theft seal 1 passes between the sensors 7 and 8, the electromagnetic force of the magnetic sensors 7 and 8
Resonates with the ferroelectric contained in the sensor, and the dielectric reflected radio waves can be detected by the sensors 7 and 8 to activate the alarm.

A conductive paint having a high resistivity is printed on the surface of the substrate 2 as the radio wave transmitting layer 3. Alternatively, conductive rubber is printed on the surface of the base material 2 as the transmitting layer 3. The conductive material of the radio wave transmitting layer 3 is charged, and the radiated electromagnetic wave is
At 8, the alarm is activated.

A radio wave transmitting layer 3 is formed by laminating a material having a Seebeck effect, for example, an n-type silicon layer and a p-type silicon layer on the surface of the base material 2. If necessary, incorporate an electromagnetic coil by printed wiring. The sensor detects a discharge radio wave transmitted from the radio wave transmission layer 3.

An electromagnetic wave transmitting layer 3 is formed by printing an ultrasonic resonance material, for example, a paint (including ink) containing quartz powder or the like on the substrate 2. Ultrasonic waves are radiated as a sensor, and a resonance radio wave of the ultrasonic wave transmitting material of the radio wave transmitting layer 3 is detected by the sensor.

Since the above is a simple example, the radio wave transmitting layer 3 and the sensor suitable for this purpose can be selected in relation to the sensor.

The shape of the anti-theft seal 1 is preferably in a form that the customer does not notice. Therefore, if an arbitrary form such as a price tag, a product tag, a bar coat, a product number sticker, a store name sticker, a date sticker, or the like is taken, the anti-theft seal is not noticed.

The shape of the radio wave transmitting layer 3 is also arbitrary, such as solid painting, letters, symbols, and patterns. Further, a mode in which a seal-like material is adhered to the base material may be used. Further, it may be used in combination with an ink, or printed on a solid coating with necessary items. Further, the base material may be impregnated with a material and molded. A type in which sensors are disposed above and below a passage is also used.

[0031]

The present invention constructed as described above has the following excellent effects.

Since the anti-theft seal is a seal, it can be attached to a small product, and since the seal is small, the cost is lower than the damage caused by theft, and the seal can be disposable.

Since the radio wave transmitting layer can be formed by printing, it can be changed to characters, symbols, figures, etc., and has an effect of not being noticed by the customer.
