Description

  The present invention relates to an RFID label that is detachably attached to an adherend, and particularly relates to an RFID label that prevents an inlet from remaining on the adherend when peeled from the adherend.

  Between the adhesive paper and the backing paper, an IC chip for storing data and a planar antenna for connecting and receiving data are enclosed in an inlet disposed on one side of the film, and are attached to a product or its packaging. RFID labels that can be worn are known. FIG. 7 is a plan view of such a conventional general RFID label as seen from the adhesive surface, and FIG. 8 is a YY sectional view of the RFID label of FIG. 7 temporarily attached to a peeling mount. 7 and 8, the conventional RFID label 50 has a configuration in which an adhesive paper 53 having a first adhesive layer 52 and a surface of the inlet 54 are bonded to the back surface of the label base 51. The surface of the first pressure-sensitive adhesive layer 52 is protected by being temporarily attached to the release mount 55.

  The RFID label 50 is affixed to an adherend such as a component, a product, and a package thereof, and is used for management of information regarding the name and various histories of the component and the product. Many RFID labels were discarded after use without being reused. However, in recent years, from the viewpoint of effective use of resources, a part or all of the inlet 54 of the RFID label 50 including the inlet 54 is peeled off after use, and the inlet 54 is reused or the product is displayed before the product is displayed at the storefront. Label 50 is peeled off and collected for use as an acceptance record, or used for applications such as removing the RFID label 50 cleanly before selling the product to consumers so as not to impair the beauty of the product's cosmetic box. There is a need for RFID labels that can be made. For such applications, the affixed RFID label 50 needs to be easily peeled off. Therefore, with a strong adhesive premised on permanent adhesion, which has been used in the past, the product or package can be removed at the time of peeling. There was a case to hurt. For this, an adhesive that is weaker than the first adhesive layer 52 and can be re-removed is used, and the RFID label 50 can be easily peeled off. The illustrated RFID label 50 is known (see Patent Document 1).

  However, since the RFID label 50 must be attached to the adherend only with the first adhesive layer 52 having a limited area excluding the inlet 54, the adhesive strength of the first adhesive layer 52 is weakened. However, although the RFID label 50 can be easily peeled off, there is a problem that the RFID label 50 is easily peeled off and attached to a product or the like during distribution. Therefore, the second adhesive layer 56 is provided on the back surface of the inlet 54 to prevent the dropping. However, if the adhesive force of the second adhesive layer 56 is too strong, as shown in FIG. When the edge of the paper 53 is lifted and peeled off from the adherend 57 in the F direction, the inlet 54 to be recovered is peeled off between the first adhesive layer 52 and the inlet 54 having a weak adhesive force. There is a problem that it remains on the adherend. If the inlet 54 remains, not only the work of peeling the adhesive paper 53 but also the work of peeling the inlet 54 is required, which causes inconvenience that the work efficiency is reduced twice, so that this can be avoided. There was a problem that detailed and complicated adjustment of the adhesive strength of the first adhesive layer and the second adhesive layer was required.

JP 2006-202169 A

  The present invention has been made in view of such problems, and an object of the present invention is to provide an RFID label that does not peel off from an adherend during use but can be easily and cleanly peeled off during use. .

  In order to solve the above-described problems, the RFID label of the present invention transmits / receives data by connecting an IC chip for storing data to the central portion of the label base material having the first adhesive layer on the back surface and connecting to the IC chip. One side of the inlet where the antenna is disposed on the film is an RFID label bonded through the first pressure-sensitive adhesive layer, and a second pressure-sensitive adhesive layer is provided on the other side of the inlet. And at least the convex corner portion of the peripheral portion of the outermost exposed surface which is the other surface side of the inlet is an easily peelable portion, and at least the first pressure-sensitive adhesive layer and the second pressure-sensitive adhesive. It is characterized in that the layer can be attached and peeled from the adherend.

  Moreover, the whole surface of the said peripheral part can be made into the said easy peeling part.

  Moreover, the said easy peeling part can be made into the paste-free part in which the said 2nd adhesive layer is not provided.

  In addition, the easily peelable portion can be an adhesive strength adjusting portion in which the surface of the second pressure-sensitive adhesive layer is covered with printing ink or the like to reduce or eliminate the adhesive strength.

  In the RFID label of the present invention, an IC chip for storing data and an antenna for transmitting and receiving data connected thereto are arranged on the film with respect to the central portion of the label base material having the first adhesive layer on the back surface. One side of the inlet is an RFID label that is bonded via a first pressure-sensitive adhesive layer, and a second pressure-sensitive adhesive layer is provided on the other side of the inlet and the other side of the inlet. Of the peripheral edge of the outermost exposed surface, at least the convex corner is an easily peelable part, and is attached to the adherend with at least the first pressure-sensitive adhesive layer and the second pressure-sensitive adhesive layer. Since it can be peeled, there is an effect that it is not peeled off from the adherend during use and can be easily and cleanly peeled off from the adherend.

  Moreover, since the whole surface of a peripheral part can be made into an easily peelable part, when peeling from a to-be-adhered body, there exists an effect that it can peel cleanly from where it peels.

  Moreover, since an easy peeling part can be made into the paste-free part in which the 2nd adhesive layer is not provided, there exists an effect that it can peel from a to-be-adhered body cleanly.

In addition, the easy peeling part can be used as an adhesive strength adjusting part where the surface of the second pressure-sensitive adhesive layer is covered with printing ink or the like and the adhesive strength is reduced or erased. In addition, it has the effect of being easy to manufacture.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a plan view showing a configuration of an RFID label according to an embodiment of the present invention as seen from the adhesive surface, and FIGS. 2A and 2B are RFID labels of FIG. 1 attached to a release mount. FIG. 3 is a cross-sectional view of the inlet, and FIG. 3 is a cross-sectional view of the inlet.

  1 to 3, the RFID label 1 according to the present embodiment is provided with a first pressure-sensitive adhesive layer 3 on the entire surface with respect to the back surface of the label base 2 that is printed on the front surface or printed by a printer. Further, an IC chip 5 for storing data and a planar antenna 6 for transmitting and receiving data connected thereto are provided on the film 7 through the adhesive paper 4 and the first adhesive layer 3. Consists of a rectangular inlet 8 and a second adhesive layer 10 provided at the remaining central portion of the rear surface (open surface) of the inlet 8 where the peripheral edge portion is removed as a non-glue portion 9 with a predetermined width. Has been.

  When the RFID label 1 is peeled off, the non-glue portion 9 (easy peeling portion) on the peripheral edge of the back surface of the inlet 8 is a trigger for peeling in order to prevent the inlet 8 from remaining on the adherend 11. In general, the wider the width, the easier it is to peel off. This width depends on the thickness (waist strength) of the label substrate 2 and the inlet 8, but generally it should be 1 mm or more, more preferably 2 mm or more. By the way, the easy peeling part does not necessarily need to be the non-glue part 9 as shown in FIG. 2A, and when the edge of the adhesive paper 4 is pulled up for peeling, the first adhesive layer 3 is used. And the inlet 8 may be set so that the peeling force is small enough not to peel off. Therefore, as shown in FIG. 2B, the second pressure-sensitive adhesive layer 10 is provided on the entire surface of the back surface of the inlet 8 and has a predetermined width with respect to the peripheral edge of the surface of the second pressure-sensitive adhesive layer 10. Alternatively, the adhesive strength adjusting unit 12 may be configured such that the adhesive strength is reduced or eliminated by covering with UV ink or the like by a printing means or a coating means. The adhesive force in this case is preferably in a completely erased state, but it may be in a state where the adhesive force is partially reduced by covering the peripheral edge of the back surface of the inlet 8 with a halftone dot or the like.

  As shown in FIG. 3, the inlet 8 is one in which an antenna 6 and an IC chip 5 connected thereto are mounted on one surface of a film 7 such as PET (polyethylene terephthalate). In FIG. 3, the film 7 constituting the inlet 8 is a single sheet, and the antenna 6 and the IC chip are mounted in a state of being exposed on one side of the film. The inlet 8 may be configured such that the antenna 6 and the IC chip 5 connected thereto are sandwiched between two films 7.

  2 (a) and 2 (b), the surface of the inlet 8 on which the antenna 6 and the IC chip 5 are provided may be directed to the first pressure-sensitive adhesive layer 3 side. You may turn to the side. However, when the RFID label 1 is affixed to a product or the like, there is a risk of damage to the IC chip 5 due to an impact from the surface of the RFID label 1, so that the exposed surfaces of the antenna 6 and the IC chip 5 are Generally, it is arranged so as to face the second pressure-sensitive adhesive layer 10. However, when the strength of the label substrate 2 is high, or when the adherend 11 has irregularities and it is necessary to prevent the influence from the adherend 11, the surface of the first adhesive layer 3 is faced. You may arrange so that.

  Further, the RFID label 1 of the present embodiment may be temporarily attached to the release mount 13 on the surfaces of the first adhesive layer 3 and the second adhesive layer 10 during storage. The material 2, the first pressure-sensitive adhesive layer 3, and the second pressure-sensitive adhesive layer 10 may be faced and wound in a roll shape. In addition, when winding in roll shape, it is desirable to give the surface of the label base material 2 an easy peeling process for facilitating the peeling of the adhesive with silicone or the like.

  The type and material of the label substrate 2 are not particularly limited, and those generally used as labels can be used. Preferably, coated paper having excellent printability and printability by a printer, Art paper, fine paper, matte paper, cardboard, paper-based substrates such as thermal paper, resin film-based substrates such as PET (polyethylene terephthalate), PP (polypropylene), PE (polyethylene), PS (polystyrene), and synthetic materials Composite substrates such as paper can be used.

  It does not specifically limit regarding the material of the adhesive used for each of the 1st adhesive layer 3 and the 2nd adhesive layer 10, The general thing used for the adhesive paper 4 can be used, For example, pressure sensitive adhesives such as natural rubber, synthetic rubber, acrylic resin, polyvinyl ether resin, urethane resin, and silicone resin can be used.

  Next, a case where the RFID label 1 attached to the adherend 11 is peeled will be described with reference to FIG. 4 and FIG. 9 shown as a conventional example. Here, in FIG. 4, the right end portion of the adhesive paper 4 of the RFID label 1 shown in FIG. 2A is pulled up in the F direction to peel the first adhesive layer 3 from the adherend 11. It is explanatory sectional drawing which shows a state. In FIG. 4, the force for pulling up the adhesive paper 4 is the adhesive portion of each layer laminated on the lower layer, that is, the boundary between the first adhesive layer 3 and the surface of the inlet 8, the inlet 8 and the second adhesive. It acts on the boundary part of the layer 10 and the boundary part of the second pressure-sensitive adhesive layer 10 and the adherend 11 to try to peel them off from the tip. According to the present embodiment, the adhesive-free portion 9 at the end portion (peripheral portion) of the inlet 8 is pulled up while being curved following the pressure-sensitive adhesive paper 4 due to the force of pulling up the pressure-sensitive adhesive paper 4, so that the first part of peeling is started. The force acting on the tip of the boundary between the pressure-sensitive adhesive layer 3 and the surface of the inlet 8 is equivalent to the presence of the non-glue portion 9 compared to the conventional RFID label 50 shown in FIG. , It becomes smaller depending on its length. In the present embodiment, the adhesive force between the inlet 8 and the boundary portion of the second adhesive layer 10 is sufficiently stronger than the adhesive force at the boundary portion of the second adhesive layer 10 and the adherend 11. Furthermore, the inlet 8 is flexible enough to follow the adhesive paper 4 and bend, and the non-glue portion 9 is sufficient from the tip of the peeling to the extent that the inlet 8 can be bent. Since the width is provided, the RFID label 1 is peeled from the boundary between the second pressure-sensitive adhesive layer 10 and the adherend 11 without peeling off the surface of the first pressure-sensitive adhesive layer 3 and the inlet 8. It has come to be. With such a configuration, there is an effect that the problem that the adhesive paper 4 is peeled off from the inlet 8 before the inlet 8 is peeled off from the adherend 11 is less likely to occur.

  In addition, in FIG.2 (b), when adhesive force remains in the adhesive force adjustment part 12 (easy peeling part), the peeling force of the boundary part of the adhesive force adjustment part 12 and the to-be-adhered body 11 is, It is necessary to set the adhesive force of the first adhesive layer 3 and the second adhesive layer 10 so as to be smaller than the peeling force at the tip of the boundary between the first adhesive layer 3 and the surface of the inlet 8. is there. Thus, the RFID label 1 is peeled off quickly by the same effect as in the case of FIG. 2A after the peeling to the interface part of the second pressure-sensitive adhesive layer 10 is promptly performed and the adhesive force adjusting part 12 is peeled off. Is called.

  That is, in this embodiment, an easy peeling portion is provided for the entire peripheral edge of the inlet 8, and the peeling is performed as shown in FIG. The adhesive paper 4 is peeled from the inlet 8 before the inlet 8 is peeled off from the adherend 11 as described above. There is an effect that it is difficult to cause the problem.

  FIG. 5 is a plan view showing the configuration of the RFID label 1 according to the second embodiment of the present invention. In the present embodiment, the first pressure-sensitive adhesive layer 3 while the short portion and the long portion of the rectangular inlet 8 that is smaller than the center portion of the substantially rectangular pressure-sensitive adhesive paper 4 correspond to each other. The rectangular inlet 8 is provided with a second pressure-sensitive adhesive layer 10 on the back surface, and at both end edges of the short portion (the short portion side of the adhesive paper 4) with a predetermined width. Easy peeling part 9 (12) is provided. The easy-to-peel part 9 (12) is provided on the short side. Normally, when the label is peeled off by hand, the four corners of the easy-to-peel label are peeled off with nails, or the short part of the label is peeled off with nails. Then, it is based on the knowledge that it is carried out by picking up the end with a finger and lifting it up. By having comprised in this way, in this Embodiment, before the inlet 8 peels from the to-be-adhered body 11 like 1st Embodiment, the easy peeling part 9 (12) peels as a head of peeling. As a result, the second adhesive layer 10 and the adherend are smoothly peeled from each other, and the effect that the adhesive paper 4 peels off from the inlet 8 is less likely to occur. In addition, when the short part side of the adhesive paper 4 corresponds to the long side of the inlet 8, the easy peeling part 9 (12) may be provided at both ends of the short part side of the inlet. It is more preferable to provide easy peeling portions at both end edges.

  FIG. 6 is a plan view showing the configuration of the RFID label 1 according to the third embodiment of the present invention. In the present embodiment, easy peeling portions 9 (12) are provided at the four corners of the inlet 8. In many cases, the label is peeled by hand by peeling off the four corners of the label with a nail and then picking up the edges with a finger. Further, even when the short part of the label is pinched and peeled off, it is difficult to peel off in parallel, and in many cases, the label is bent and any of the four corners becomes the head of peeling. Therefore, even if the easy peeling portions 9 (12) are provided only at the four corners of the RFID label 1, the second adhesive layer 10 and the adherend are smoothly peeled, so that the inlet 8 is stuck. There is an effect that the problem that the adhesive paper 4 is peeled off from the inlet 8 before being peeled off from the adherend 11 hardly occurs.

  As described above, the RFID label of the present invention is a film in which the IC chip for storing data and the antenna for transmitting and receiving data connected to the central portion of the label base material having the first adhesive layer on the back surface are films. One side of the inlet arranged on the top is an RFID label bonded via a first pressure-sensitive adhesive layer, and the other side of the inlet is provided with a second pressure-sensitive adhesive layer. Of the peripheral edge of the outermost exposed surface on the other side, at least the corner portion is an easily peelable portion, and at least the first adhesive layer and the second adhesive layer with respect to the adherend Since it can be attached and peeled off, it does not peel off from the adherend during use, and can be easily and cleanly peeled off from the adherend.

  The present invention is not limited to the above-described embodiments, and it is obvious that each embodiment can be appropriately changed within the scope of the technical idea of the present invention. In addition, the number, position, shape, and the like of the constituent members are not limited to the above-described embodiment, and can be set to a suitable number, position, shape, and the like in practicing the present invention.
