Description

  The present invention relates to a metal lid provided in a metal container such as an aluminum can or a steel can, and more particularly to a metal lid with an IC tag and a metal container on which an IC tag that performs wireless communication with a reader / writer is mounted.

In general, metal containers such as aluminum cans and steel cans are used for, for example, carbonated beverages such as beer, cola, cider, fruit juice beverages, various tea beverages, canned food containers, various liquid product containers, etc. Widely used.
Such various metal containers are provided with characters, bar codes, or the like displaying predetermined product information such as product names, contents components, producers, production locations, expiration dates, and the like. This kind of product information display is usually printed directly on the outer surface of a metal container or printed on a label.

However, labels and prints for displaying product information are generally displayed small so as not to impair the design of the container. As a result, the display area, the size of characters to be displayed, the number of characters, etc. are limited. There was a problem that sufficient product information could not be displayed.
In the case of bar code display, the bar code itself must be displayed in a flat shape on the surface of the container in order to be read by a reader. Since the amount of information that can be encoded with a code is limited, there is a certain limit as a means for displaying and recognizing product information, as in the case of display by characters.

Therefore, as a means for eliminating such disadvantages and inconveniences of conventional product information display and displaying necessary and sufficient product information simply and accurately, an IC tag has recently been used.
An IC tag is also called a non-contact IC tag, RFID (Radio Frequency Identification) tag, RF tag, etc., and is an ultra-compact type in which an IC chip and a wireless antenna are sealed with resin, glass, etc. and formed into a tag (tag) shape. The communication terminal records predetermined information on the IC chip, attaches a tag to the object, and picks up the recorded information on the reading device (reader / writer) side by wireless communication. Recognize and display.

Such an IC tag can record hundreds of bytes to several kilobytes of data in the memory of the IC chip, can record sufficient information, etc., and is non-contact with the reader side, so that the wear or damage of the contacts In addition, there is no worry about dirt, etc. Furthermore, since the tag itself can be powered off, it is possible to process it according to the object and to make it smaller and thinner.
By using such an IC tag, various information related to the product, such as the name and weight of the product, the content, the name of the manufacturer / seller, the manufacturing location, the date of manufacture, the expiration date / expiration date, etc. Information can be recorded, and even a wide variety of product information that was impossible with conventional product display using characters and barcodes can be used simply by attaching a small and thin tag to the product. It became possible.

However, when such an IC tag is attached to a metal container such as an aluminum can or a steel can, there is a problem that the IC tag is affected by the conductivity of the metal container and accurate wireless communication cannot be performed. .
When the IC tag is attached to the container, the magnetic flux generated by the IC tag is generated in a direction penetrating the container. For this reason, when a tag is attached to a metal container, a heat loss or the like in which a magnetic wave / electromagnetic wave generated by the antenna unit is absorbed to the metal container side occurs, and the communication characteristics of the tag are impaired.

For example, when the IC tag 100 is attached to the metal container 101 as shown in FIG. 9A, an eddy current is induced on the surface of the metal container 101 by the magnetic flux generated by the tag 100 as shown in FIG. 9B. The eddy current cancels out the magnetic flux of the IC tag 100 and causes heat loss. Also, the inductance of the antenna coil portion of the tag 100 changes due to the influence of the metal container 101, thereby causing resonance of the resonance circuit of the antenna. The frequency will also shift.
In this way, when a general-purpose IC tag that is generally used is attached to a metal container as it is, a problem occurs that the tag malfunctions or wireless communication with a reader / writer cannot be performed.

So far, when attaching an IC tag to a metal container such as an aluminum can or a steel can, a proposal to change the configuration of the IC tag to a dedicated one for the metal container to avoid the influence from the metal container (For example, refer to Patent Documents 1-3.)
Specifically, as shown in FIG. 10, a conventionally proposed IC tag 102 dedicated to a metal container has a magnetic body (high magnetic permeability) formed in a sheet shape or the like on the side facing the metal container 101 inside the tag. Body) 103 and a dielectric are arranged, thereby preventing the magnetic flux generated by the IC tag 102 from passing through the magnetic body 103 and preventing an eddy current from being generated on the metal container 101 side. It was like that.

JP 2002-207980 (page 2-4, FIG. 1) Japanese Unexamined Patent Publication No. 2004-127057 (page 3-4, FIG. 1) JP 2004-164055 A (page 4-5, FIG. 1)

However, the conventionally proposed IC tags for metal containers have larger dimensions such as thickness compared to general-purpose IC tags, and when attached to the surface of a metal container, it is clear that the tags are apparently attached. This may damage the appearance of the metal container and may be damaged by contact with other products or equipment when shipping or displaying the product. It was possible, and there was a possibility that the management system would be hindered.
Although it is possible to reduce the size of the IC tag so that it does not stand out from the outside, in this case, the required antenna length cannot be secured, and the wireless communication distance (range) is limited to a narrow range. The communication characteristics may be impaired due to the influence of adjacent metal containers.

  The present invention has been proposed in order to solve the problems of the conventional techniques as described above, and has a metal lid that is unlikely to come into contact with other products or instruments or to be hidden by an adjacent metal container. By mounting an IC tag that is insulated and sealed on the IC tag, the IC tag can be mounted without impairing the appearance of the container, and the IC tag can be prevented from being damaged. It is an object of the present invention to provide a metal lid with an IC tag and a metal container that can perform good wireless communication with the device.

It is comprised with the metal lid | cover 30 used as a part.
An IC tag 40 that communicates with the reader / writer is attached to the metal lid 30 of the metal container 10.

Here, in the case of a so-called three-piece can, the can container constituting the metal container 10 is formed by winding the lid part and the bottom part around the trunk part, and the trunk part and the lid part and the bottom part are separated from each other. In the case of a so-called two-piece can, the bottom portion and the trunk portion are integrated to form a container body, and the lid is wound around the container body.
The metal container 10 of this embodiment is configured by a two-piece can that winds a metal lid 30 that forms a lid on a container body 20 that forms a trunk and a bottom.
However, the metal container 10 may be constituted by a three-piece can.

As shown in FIGS. 2 and 3, the winding portion between the container body 20 and the metal lid 30 includes a body hook 21 formed on the upper edge of the container body 20 and a cover formed on the outer peripheral edge of the metal lid 30. It is formed by overlapping the hook 31 and pressing it in a wound shape.

The communication distance that enables wireless communication varies depending on the frequency band used, and the optimum antenna length and wiring pattern vary depending on the frequency band.
In the present embodiment, a linear non-spiral pattern is adopted as the wiring pattern of the antenna 42 suitable for the 2.45 GHz band. However, an arbitrary wiring pattern such as a non-linear spiral pattern or a linear spiral pattern can be used as the antenna pattern.

The insulating member 44 that insulates and seals the IC tag 40 is made of a material that electrically insulates the IC tag 40 and the metal lid 30 and includes, for example, urethane resin, polyester resin, polypropylene resin, phenol resin, and rubber. When embedding with a resin, an isocyanate resin may be mixed as a curing agent with a urethane resin or a polyester resin.
Further, the insulating member 44 is preferably a member having a certain elasticity so that it can be press-fitted into the ring hole 38 of the opening tab 33, and natural rubber, styrene rubber (SBR), butadiene rubber ( BR, chloroprene rubber (CR), butyl rubber (IIR), nitrile rubber (NBR), ethylene propylene rubber (EPM), hyperon (CSM), acrylic rubber (ACM), silicone rubber, urethane rubber, fluorine rubber, etc. It is preferable to do.

The IC tag 40 is sealed by the insulating member 44 as follows, for example.
