Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminated packaging material capable of preventing the opening or tampering of an article (commodity) such that the packaging material is broken by "mischief" or the like, and a method for detecting the laminated packaging material.

[0002]

BACKGROUND OF THE INVENTION Businesses take great care to provide consumers with security from manufacturing to purchase. However, at times, an inexperienced person who performs "mischief" or the like may cause an unexpected situation in which the packaging container is broken and opened / tampered. In particular, direct food, cosmetics, pharmaceuticals, etc.
From the viewpoint of safety and hygiene, it is necessary to absolutely prevent the packaging of products that affect the human body from being intentionally opened and altered in the distribution process during the distribution process.

[0003] As a method for preventing this, shrink wrapping and an overwrapper using a film of polypropylene, polyethylene, polyvinyl chloride, etc., and in order to take out a product (article), paper or aluminum foil as a wrapping material is used. In accordance with the purpose, contents, and form of the packaging container, various types of containers, such as bottles and films that must be cut, and bottle caps, etc. that cannot be removed without stripping a plastic protective strip around the belt, etc. The ingenuity is adopted.

[0004] However, even if these measures are taken, it is expected that they are sometimes finely crafted. In addition, when such an unexpected situation occurs, the above-described prevention means requires a person to visually check the goods (products) one by one, which requires a large amount of labor. Sometimes there is a risk of overlooking.

[0005]

The problem to be solved by the present invention is to use the above-described opening prevention means and a packaging material in which a non-contact IC tag is laminated, or to provide a packaging in which a non-contact IC tag is laminated. By using the material alone and displaying an alarm sound and an alarm display based on information transmitted from the non-contact IC tag when passing through a cash register, etc., it is possible to more reliably detect that the product has been opened and tampered with, An object of the present invention is to reduce the labor for detecting a tampered product (commodity).

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings.

The non-contact IC chip used in the present invention is not an electromagnetic coupling type in which an antenna portion is formed in a loop shape,
An electrostatically-coupled non-contact IC in which two independent antenna portions are formed without any portion where the antenna portions are in contact with each other
Chip. The most common non-contact IC tag of the electrostatic coupling type has a configuration in which a pattern of a conductive layer is formed like a butterfly wing and an IC chip is provided at the center as shown in FIG. . An antenna portion (12a, 12b) of a conductive layer (12) is formed on a lower substrate (11) of a plastic such as paper, polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, or the like. The antenna portions (12a, 12b) have no portions in contact with each other and are formed separately and independently. This conductive layer (1
2) An electrostatic coupling type non-contact IC chip (13) is joined to the antenna units (12a, 12b). The upper base material (14) is laminated on the lower base material with the same paper as the lower base material, plastic such as polyethylene, polypropylene, polyvinyl chloride, and polyethylene terephthalate.
As described above, the IC chip is sandwiched between the upper base material (11) and the lower base material (14), and each base material is printed with the name of an article or the like.

According to the present invention, as shown in FIG. 2 (a), a conductive layer (12) forming an antenna portion is connected to a lower substrate (11), and an electrostatic coupling type is formed thereon. Non-contact I
The C chip (13) is provided on the conductive layer. This figure 2
(A) By breaking the lower base material (11) at the tearing portion (15), two separate and independent antenna portions (12a, 12b) are formed as shown in FIG. You will be able to exchange information with external devices that are leaders. Although not shown in FIG. 2, it is natural that the upper base material is provided and laminated. The present invention applies this fact to prevent the opening and tampering by using a packaging material in which an electrostatically-coupled non-contact IC chip (13) is embedded and laminated, and easily detects this. It is.

FIG. 3A shows an example in which a pattern of a conductive layer (12) serving as an antenna portion is formed along the outer periphery of a lower substrate (11). In this case as well, the lower substrate (11) in FIG.
By forming two separate and independent antenna units (12a, 12b) as shown in (b), information can be exchanged with an external device.

FIG. 5 (a) shows a structure of a packaging material in a case where a packaging material on which an electrostatic coupling type non-contact IC chip is laminated is sealed on four sides to produce a bag-shaped packaging container. Of 1
An example is shown in FIG. When removing or falsifying the contents of the bag with the four sides sealed, the end of the bag-like packaging container is inevitably cut off, so that the laminated packaging having the conductive layer (12) at the end is provided. FIG. 4A is a perspective view of the material. 4 (a) and 5 (a), when one end of the end is cut off, two independent antenna portions are formed,
Information can be transmitted and received without contact with external devices. FIG.
FIG. 4B is a cross-sectional view of the configuration taken along the line xx in FIG.
A barrier film (16) such as nylon or vinylidene chloride on which inorganic oxides for protecting the contents are deposited on a base material (11) of paper or plastic film, and a conductive layer pattern (12) with a conductive ink thereon; It is provided with an electrostatic coupling type IC chip (13), an upper substrate (14), and a sealant layer (17) for sealing.

Non-contact IC of electrostatic coupling type used for this
As the chip (13), there is BIStatix (bistatics) manufactured by Motorola, Inc. of the United States. Further, the layer configuration of the laminated packaging material is not limited to the mode shown in FIG. 4, but is appropriately designed in consideration of the mode of packaging, contents, and the like. In addition, if consideration is given to environmental problems when disposed of, biodegradable paper may be mainly used as the base material.

FIGS. 5 (b) and 5 (c) show a packaging material obtained by laminating this electrostatically-coupled non-contact IC chip on a top-openable container or bottle, and affix it to the take-out opening. This is an example. In this case as well, this label must be torn in order to be opened / falsified, and when it is torn, communication with an external device becomes possible as described above.

As an example of detecting whether or not an article (article) has been opened or tampered with, an external device (20) which is a reader for exchanging information with an IC when purchasing the article (article) and paying out at a cash register. ). If the package has been opened, information indicating "opened" is displayed on the IC or an alarm is issued. If the IC chip has not been opened or tampered with, the IC chip does not function as a non-contact IC, so that no display or alarm is issued.

Although the packaging material in which the IC chip of the present invention is laminated may be used alone to prevent opening and tampering, it can be more reliably prevented from being opened and tampered with other tampering and prevention means. it can.

[0021]

As described above, since the conductive layer is cut off to form two separate and independent antenna portions, information can be exchanged without contact with an external device. This eliminates the need for visual opening and tampering. In addition, by using it in combination with other tampering / prevention means, what has been visually overlooked can be backed up, and opening / tampering can be prevented more reliably.
