Characteristic sealing seal. (A) An adhesive layer is provided on the back surface of the sealing material, and the adhesive strength of the adhesive layer is such that the sealing material breaks when the sealing material is peeled off. A conductive portion is provided on the surface to traverse the two opening and closing members, and the conductive portion has conductivity. A plurality of second conductive members traversing the two opening and closing members are provided on the surface of the sealing material. May be provided, and at least one of the second conductive portions may be conductive to the conductive portion.

Further, a third conductive portion which is not conductive to the conductive portion may be provided on the surface of the seal material.

Further, it is preferable that the surface of the sealing material has the same color as the conductive portion.

[0008]

FIG. 1 is a plan view and a sectional view of a sealing seal according to the present invention. This sealing seal 1 is sealed so that two openable members such as a closed package cannot be opened without permission. An adhesive layer 3 is formed on the back surface of a substantially rectangular seal material 2 made of a material that is easily torn, such as paper, and is adhered on a release paper 4. The adhesive force of the adhesive layer 3 is set to such a strength that the sealing material 2 can be broken before peeling when the sealing material 2 attached to the package is to be peeled.

Then, in the vicinity of the peripheral edge of the surface of the sealing material 2, the one end 2a returns to the other end 2a via the other end 2b, and when the package 10 is sealed, the upper member 10a and the lower member 10b are separated. A substantially U-shaped conductive portion 5 is provided so as to cross the member. The conductive portion 5 is formed by conductive printing such as conductive carbon printing.
Are formed so as to have a large area so that electrical contacts can be easily contacted. One end is a common terminal 5a, and the other end is a conduction detection terminal 5.
b, so that if there is conduction between the common terminal 5a and the conduction detection terminal 5b, it can be determined that the sealing seal 1 is not broken.

Next, a case in which the sealing seal having the above configuration is attached to a package will be described. FIG. 2 shows an example of the package 10, and the package 10 contains the product 12 to be put therein.
Consists of a blister package consisting of two openable and closable upper and lower members 10a and 10b made of a transparent synthetic resin visible from the outside.
a and the lower member 10b are formed so that a flange 11 formed on the edge thereof overlaps with the lower member 10b.
From the center after peeling off from
May be sealed so as to sandwich the predetermined position from above and below.

The seal 1 for sealing the package 10 as described above may be checked by, for example, a reading device A as shown in FIG. The reading device A includes a terminal 5a of a conductive portion 5 formed on one end 2a of the sealing material 2,
A reading unit 15 provided with reading terminals a1 and a2 is arranged at a position corresponding to 5b. In a state where the package 10 is supported by the support unit 16, the reading terminal a1 is connected to the terminal 5a, and the reading terminal a2 is connected to the terminal 5b. Are connected to each other, and the common terminal 5a and the conduction detection terminal 5b
The current detection circuit 17 may check whether a current flows between them.

If there is continuity between the terminals 5a and 5b, it is determined that the sealing seal 1 has not been broken. If there is no continuity, the continuity portion 5 is disconnected between the common terminal 5a and the conduction detection terminal 5b. That is, it can be determined that the sealing seal 1 has been broken, and it can be determined that the package 10 has been tampered with, for example, its contents have been replaced.

Further, since the sealing seal 1 has a strong adhesive force of the adhesive layer 3 and is made of easily tearable paper for the sealing material 2, it is attempted to open the package 10 or peel off the sealing seal 1. In this case, the sealing material 2 is easily torn, and when the package 10 is opened, the sealing seal 1 is torn without fail, thereby preventing the injustice of replacing the contents of the package 10 without damaging the sealing seal 1. it can.

Further, since the conductive portion 5 is formed along the peripheral edge of the sealing material 2, even if the sealing material 2 is not completely broken, a part of the sealing material 2 is damaged. It can be broken to interrupt conduction.

Next, a description will be given of a sealing seal for checking whether or not the package has been opened and for providing information.

This sealing seal 21 is shown in FIGS.
As shown in the figure, three second conducting portions 6 in addition to the conducting portion 5,
7 and 8 are printed. The second conductive portions 6, 7, 8
Are end portions 6a and 7 of portions located on one end side of the sealing material 2.
a, 8a are formed so as to have a large area so as to be easily in contact with the electrical contact, and the other end portions 6b, 7b, 8b are located near the conducting portion 5 across the two opening / closing members 10a, 10b,
Some of the second conductive portions 8 are connected to the conductive portion 5. The second conductive portions 6, 7, and 8 constitute a data portion, and a maximum of eight types of sealing seals can be formed from a combination based on the presence or absence of conduction between the conductive portion 5 and the common terminal 5a.

In order to read the sealing seal 21 provided with the second conducting portions 6, 7, 8 in addition to the conducting portion 5, the reading device also has five terminals 5a, 5b, 6a, 7
What is necessary is just to prepare the reader which provided the electric contact in the position corresponding to a and 8a. In the present invention, the number of the second conductive portions is three, but the number of types of sealing stickers having data can be increased by increasing the number. However, the amount of data (the type of seal) is limited due to the size of the seal material and the accuracy of the sticking position.

According to the above-mentioned sealing seal, if the goods and data in the package correspond to the sealing seal, the goods and data can be confirmed. For example, a vending machine that sells unprocessed products placed in a package and a processing device that processes the sold products are arranged as a set,
In the case where a product with a package paid out by inputting a predetermined fee to a vending machine is set in the processing device without opening the package and the product is processed by the processing device, the processing device is provided with a reading device, It is possible to determine whether or not the package has been opened and read information such as the material of the product from the sticker to process the product according to the specifications.

Next, a sealing seal for protecting the once cut seal from unauthorized use will be described. As shown in FIG. 4, the sealing seal 31 is formed by printing a third conductive portion 9 on one end of the surface of the sealing material 2 independently of the other conductive portions 5, 6, 7, and 8. The reading device that reads the seal 31 may determine whether there is conduction between the third conduction portion 9 and the common terminal 5a. In a normal state, there is no conduction between the third conduction part 9 and the common terminal 5a. However, when there is conduction, it is determined that a conductive sheet such as an aluminum foil is superposed on the sheet. Can be expected to commit fraud.

Further, as shown in FIG. 5, the sheet material 2 is made the same color as each of the conductive portions 5, 6, 7, and 8, or each of the conductive portions 5,
6, 7, and 8 may be printed in the same color as the sheet material 2. According to the sealing seal 41, since the shape of the conductive portion cannot be read visually, unauthorized use such as falsification of data or connection of a cut portion can be reliably prevented.

[0021]

According to the first aspect of the present invention, when the seal for sealing is to be peeled off, the adhesive force of the adhesive layer is strong, so that the sealing material is necessarily broken. When the seal material is broken, a part of the conductive portion provided on the surface of the seal material is cut, so by checking the conduction between both ends of the conductive portion, the seal material is broken even by an electrical check without a visual check. Can be determined. In addition, the manufacturing cost of the sealing seal can be kept low, and the cost-effectiveness is remarkably improved.

According to the second aspect of the present invention, it is possible to check for breakage of the sealing seal and to make the sealing seal meaningful. Can be

According to the third aspect of the invention, unauthorized use can be prevented.

According to the fourth aspect of the present invention, since the shape of the conducting portion cannot be read visually, unauthorized use can be reliably prevented.
