Description

  The present invention relates to an RFID label sheet and an RFID label for attaching RFID (Radio Frequency Identification) to an article so as to perform contactless communication with a reader / writer.

  In recent years, a technology related to non-contact type IC media called RFID has been rapidly advanced, and an IC chip to be mounted has become smaller and cheaper. This RFID is produced by forming an antenna pattern as an antenna portion on a base material and attaching an IC chip mounted inlet to another base base material. An RFID label is formed by applying an adhesive to the material. Such an RFID label is affixed to an article and used for article management by non-contact communication with a reader / writer. However, it is necessary to avoid a communication failure when the surface of the article to be affixed is metal or the like. is there.

  Conventionally, when attaching an RFID label to an article such as a metal that is prone to communication failure, it has been known that the more the RFID inlet is separated from the metal surface, the easier it is to avoid the communication failure. Has been. For example, when an RFID label is affixed to a metal surface article, the RFID inlet portion is singly or a part of the antenna is folded (Patent Documents 1 and 2), or the RFID label sheet is folded into a hollow rectangular column. It has been proposed to stand (Patent Document 3).

  In addition, in order to separate the RFID inlet portion from the metal surface of the article, a part of the label base on which the RFID inlet is formed is folded so as to sandwich the RFID inlet and temporarily attached to the mount. It has also been proposed that the RFID inlet is separated from the mount, and the RFID inlet is separated from the adherend by standing and attaching a folded portion (Patent Document 4). It has also been proposed to have a bent shape so as to form a space region with the surface (Patent Document 5).

  However, as in Patent Documents 1 to 4, folding or standing a part of an RFID inlet part or an antenna, or folding a RFID label sheet into a hollow quadrangular prism is a reader / writer. In the state of communicating with the antenna, at least the antenna has an angle in the spatial direction from the article surface. That is, when the communication frequency is in a micro frequency band (for example, several hundred to 2045 GHz), the directivity becomes narrow, and there is a problem that the positional relationship with the reader / writer is limited and restricted with respect to the RFID inlet or the antenna.

  In that respect, Patent Document 5 differs from Patent Documents 1 to 4 in that the RFID inlet is attached to the article in a flat state or a substantially flat state and is not restricted by the positional relationship with the reader / writer. When sticking, the RFID inlet portion must be three-dimensionally raised, and there is a problem that sticking workability is not preferable.

  Therefore, the present invention has been made in view of the above problems, and there is no restriction on the positional relationship with respect to the reader / writer, and there is a new form in which the RFID inlet is separated from the surface of the article with good workability for attaching to the article. An object of the present invention is to provide an RFID label to be made.

  In order to solve the above-described problem, the invention of claim 1 is an RFID label sheet that can be communicated with a reader / writer in a non-contact manner with respect to information related to an article by being affixed to the article, and an antenna on the substrate A label cover paper including an RFID inlet on which an IC module composed of a part and an IC chip is formed, an intermediate member for releasably bonding the label cover paper via a peelable adhesive layer, and the label cover paper An adhesive layer provided at least on the outer periphery on the back side of the label, and the label top paper is partially peelable by the peelable adhesive layer from the intermediate member at a predetermined position on the base material. An engagement piece receiving portion is formed, and the region including the RFID inlet and the engagement piece are integrated, and an internal space is provided on the engagement piece receiving portion side to be folded back. The a structure in which part peeling freely folded portion is formed in the peeling adhesive layer from the intermediate member to engage to the engaging piece receiving portion is partially peeled off.

  According to a second aspect of the present invention, there is provided an RFID label produced from the RFID label sheet according to the first aspect, wherein a folded portion formed on the label upper paper is peeled off from the intermediate member by the peelable adhesive layer. An internal space is provided on the side of the engaging piece receiving portion and is folded back so that the engaging piece is engaged with the engaging piece receiving portion that is partially peeled off.

  According to the first aspect of the present invention, the intermediate member is adhered to the label paper having the RFID inlet through the peelable adhesive layer so as to be peeled off, and the intermediate member is placed at a predetermined position on the label paper. An engagement piece receiving portion that can be further partially peeled is formed, the region including the RFID inlet and the engagement piece are integrated, and an internal space is provided on the engagement piece receiving portion side so that the engagement piece is folded. By forming a folded portion that can be partially peeled off from the intermediate member so as to be engaged with the engagement piece receiving portion that has been partially peeled off, the RFID inlet is in a flat state or a substantially flat state when sticking to an article. Since there is no restriction of the positional relationship with respect to the reader / writer, the folded portion is folded back to the engaging piece receiving portion before being attached to the article, and the engaging piece is engaged with the engaging piece receiving portion. Be good Those that can be a new form to separate the RFID inlet against the article surface to good sticking workability to Luo article.

  According to the second aspect of the present invention, the folded portion formed on the label top sheet is peeled off from the intermediate member from the RFID label sheet of the first aspect, and is folded by providing an internal space on the engagement piece receiving portion side. By using the RFID label that has been returned and engaged with the engaging piece receiving part from which the engaging piece has been partially peeled off, there is no restriction on the positional relationship with the reader / writer, as in the above case, and it is also attached to the article. The RFID inlet can be separated from the surface of the article having good workability.

  Hereinafter, the best embodiment of the present invention will be described with reference to the drawings. In the present invention, the form before being attached to the article is the RFID label sheet, and the form for attaching to the article is the RFID label.

  FIG. 1 shows a configuration diagram of a first embodiment of an RFID label sheet according to the present invention. 1 (A) and 1 (B), an RFID label 11 includes an RFID inlet 12 on a base material of a label top paper 13. The RFID inlet 12 is formed with an IC module including an antenna unit and an IC chip, and is similar to the conventional one. For example, the RFID inlet 12 is formed by forming an antenna portion on a base material by printing with conductive ink, and mounting an IC chip on an end portion of the antenna portion. The label upper paper 13 is a concept including a film material in addition to paper.

  An intermediate member 14 is provided on the back surface of the label top paper 13 via a peelable adhesive layer 15. As the adhesive forming the peelable adhesive layer 15, for example, a conventionally known peelable pressure sensitive adhesive can be applied. For example, a strong adhesive such as natural latex is filled with fine particles of silica or the like. It is a thing.

  Here, the label upper paper 13 is formed with an engagement piece receiving portion 13D at a predetermined position on the base material, for example, one side is integrated with the base material and the other side is formed with a cut line (slit) 19B. The This engagement piece receiving portion 13D is partly peeled off by turning off the intermediate member 14 with the peelable adhesive layer 15.

  In addition, a folding line 20 is formed on the label upper paper 13 on the side of the engagement piece receiving portion on the base, and a cut line (slit) is formed so that the region including the RFID inlet 12 and the engagement piece 13C are integrated. ) The folded portion 13B is formed by forming 19A. In this case, the distance from the fold line 20 to the root portion of the cut line 19B (engagement piece receiving portion 13D) in the engagement piece receiving portion 13D is L0, and the distance from the fold line 20 to the root portion of the engagement piece 13C is L1. Then, the fold line 20 is arranged at a position that matches the relationship of L0 <L1.

  That is, using the fold line 20 as a guide, the engaging piece 13C is peeled off from the intermediate member 14 by the peelable adhesive layer 15 and folded back to the engaging piece receiving portion side, so that the engaging piece 13C becomes the engaging piece receiving portion 13D. By engaging, an internal space is formed at the folded portion 13B.

The RFID label 11 </ b> A is formed by letting the engaging piece 13 </ b> C of the folded portion 13 </ b> B folded between the receiving portion 13 </ b> D and the peelable adhesive layer 15. In this case, the peelable adhesive layer 15 is exposed at the folded portion 13B, and the back surface of the folded portion 13B is exposed with the peelable adhesive layer 15 left.

  The RFID label 11A as described above is not subjected to subsequent bending or the like, but simply peels off the release paper 18 to expose the adhesive layer 16, and as shown in FIG. It is affixed on top.

  As described above, since the RFID inlet 12 is arranged in a planar state or a substantially planar state, there is no restriction on the positional relationship with respect to the reader / writer, and the folded portion 13B is placed on the engagement piece receiving portion side before being attached to the article 21. Since it is only necessary to fold back and engage the engagement piece 13C with the engagement piece receiving portion 13D, the RFID inlet 12 is separated from the surface of the article having good workability on the article 21. It is something that can be done.

  Next, FIG. 3 shows a configuration diagram of a second embodiment of the RFID label sheet and the RFID label according to the present invention. In FIG. 3A, an RFID label sheet 11 is obtained by attaching a protective member 31 on a label upper paper 13 provided with the RFID inlet 12 described above, and the other configurations are the same as those in FIG.
