The present invention relates to a container for receiving a product such as a liquid, semi-solid, etc., an electronic tag attachment container having an electronic tag for identifying the product information of such a container, and a manufacturing method thereof. The present invention also relates to a radio frequency identification (RFID) system using such an electronic tag attachment container.

Background Art Conventionally, in medicine, cosmetics, etc., as a method of product information management and authenticity determination of a container in which a filling material (in other words, a product) having fluidity such as a liquid state or a semi-solid state is filled in a receiving part (that is, the container body), for example, Patent Documents Japanese Patent Application Laid-Open No. 2006-232292 is known. In the method of product information management or the like described in such a patent document, an electronic tag (in other words, an IC tag) in which at least a part of the product information is stored in an inner bottom of a container made of a material (in other words, a material) that transmits electromagnetic waves. )). In this method, a reader / writer antenna is placed on or in the surface or inside of a flat dielectric (specifically, a shelf on which an article is placed) installed in a substantially horizontal state, and a product container is placed on the reader / writer antenna. Therefore, it is possible to manage the product (in other words, the product).

However, the method of product information management and the like described in the above patent document has a problem described in the following paragraphs (A) to (D). The reason why the problems described in these (A) to (D) are caused is described in (a) to (d) described in the order after each of these (A) to (D).

(A) The substances constituting medicines and cosmetics generally have fluidity such as liquid and semi-solid, and have a lot of moisture-containing products. Therefore, in the communication method of electronic tags attached to the container, the product information of the electronic tags is It may not be read by the antenna for the reader / writer.

(a) When information transmission and reception between the reader / writer antenna and the electronic tag is made by the microwave method or the UHF band method, electromagnetic waves generated from the reader / writer antenna may be absorbed by the moisture in the product. May not be read by the reader / writer antenna.

(B) In the case of the electronic tag configured to transmit and receive information by the microwave method and the UHF band method, there is a high possibility that the product information of the electronic tag attached to the normal container body is not read by the reader / writer antenna.

(b) In the case of an electronic tag configured so that transmission and reception of information can be performed by a microwave method or a UHF band method, a dipole antenna extending generally in a substantially straight line is used as the antenna for the electronic tag. In this case, the communication distance between the reader / writer antenna and the electronic tag is greatly influenced by the length of the electronic tag antenna (that is, the electronic tag dipole antenna) constituting the electronic tag. In addition, when the electronic tag is mounted almost horizontally on the inner bottom of the substantially cylindrical container body, particularly in the case of a cylindrical container body having a relatively small inner diameter, the length of the antenna for the electronic tag when viewed from the reader / writer antenna is short ( In other words, the readout performance of the electronic tag by the reader / writer antenna is reduced. In addition, it may be considered to mount the electronic tag almost vertically in the container body. In this case, however, the height of the container body cannot be made extremely small, so that the height of the container body cannot be sufficiently reduced. In addition, even when the electronic tag is mounted on the inner bottom of the container body, in the case of a normal container body having a relatively small inner diameter, the area (i.e., the bottom area) of the inner bottom is small so that a small electronic tag (in other words, a small antenna Only electronic tags). In addition, in the case of the electronic tag configured to transmit and receive information by the electrostatic induction method, the volume of the electronic tag is large so that the contents of the container must be large in order to attach the electronic tag to the inside of the container body. There is no choice but to make the container body larger than necessary so that it can be mounted on the container body.

(C) In particular, when filling cosmetics in a container, design such as the shape and color of the container is important. However, when the outer surface of the container body is almost entirely covered with a coating layer such as a label or a coating made of a metallic paint, or when the coating layer is formed near the bottom of the outer surface of the container body, the product information of the electronic tag is read. Can't be poisoned.

(c) When a coating layer containing a metallic paint is formed near the bottom of the outer surface of the container body, electromagnetic waves generated by the reader / writer antenna cannot pass through the coating layer, thereby improving communication performance between the reader / writer antenna and the electronic tag. Degrades.

(D) The electronic tag attached to a container filled with medicines and cosmetics is used smaller than the opening area of the bent portion of the container body so that it can be mounted inside a thin, long container body. However, when such a small electronic tag is disposed on the antenna winding of the reader / writer antenna, it is difficult to read the product information of the electronic tag as the reader / writer antenna.

(d) If the small electronic tag antenna is arranged almost horizontally, it is difficult to read the product information of the electronic tag by the reader / writer antenna near the antenna line of the reader / writer antenna. In addition, when the antenna for the electronic tag is disposed outside the antenna line, the magnetic field once passing through the antenna for the electronic tag passes through the antenna for the electronic tag in a reverse direction and is canceled and canceled, thereby eliminating the product information of the electronic tag to the reader / writer antenna. It becomes difficult to read.

The present invention has been made to solve the above-mentioned problems in the method of product information management and the like described in the patent document, and in a container containing a substance such as liquid, semi-solid, etc. without damaging the appearance of the design, etc. It aims to make product information management and cliché relatively accurate.
