  Hereinafter, labels according to embodiments of the present invention will be described with reference to the drawings. In the present embodiment, the label is affixed to a packaging material such as a resin film for packaging food, a box such as a cardboard box for packaging food, and an object such as an object or place where a pest is not desired to be brought close to.

  FIG. 1 is a diagram showing a manufacturing process of a first label in the embodiment of the present invention. In the first step shown in FIG. 1A, the adhesive layer 110 is formed on the upper surface of the mount 102. The adhesive layer 110 is formed by mixing an adhesive member 112 and a microcapsule 114 encapsulating a pest repellent, and corresponds to the microcapsule layer. The repellent contains, for example, plant-derived components such as lemon and chili.

  In the second step shown in FIG. 1B, a printed layer 116 made of paper, silicon, or the like is formed on the adhesive layer 110. The upper surface of the printing layer 116 is a printing surface 117, and characters such as food names, weights, and amounts of money, and information such as barcodes and two-dimensional codes are printed on the printing surface 117. . Through such first and second steps, the first label 100-1 including the adhesive layer 110 and the print layer 116 is manufactured.

  FIG. 2 is a diagram illustrating a printing process of the first label 100-1 by the printer 200-1. The first label 100-1 is temporarily attached to the belt-like mount 102 at equal intervals. In the printer 200-1 in FIG. 2, a thermal head 206 and a platen roller 208 are arranged in the conveyance path for the mount 102 and the first label 100-1.

  The thermal head 206 is disposed at the upper part of the transport path, and the platen roller 208 is disposed at a position facing the thermal head 206 at the lower part of the transport path. The thermal head 206 inputs print data from a control unit (not shown). Then, at the timing when the first label 100-1 is transported immediately below, the thermal head 206 has information corresponding to the print data, for example, food on the printing surface 117 of the printing layer 116 of the first label 100-1. Print characters such as name, weight, amount of money, barcode, 2D code, etc.

  First, processing means for destroying the microcapsule 114 mixed in the adhesive layer 110 of the first label 100-1 by pressing force will be described. The first label 100-1 is pressed in the vertical direction by the thermal head 206 and the platen roller 208 of the printer 200-1. The microcapsule 114 mixed in the adhesive layer 110 is destroyed by this pressing force, and the internal label Dispel repellent.

  Further, the printer 200-1 may have a configuration in which the pressure rollers 202 and 204 are disposed on the downstream side or the upstream side of the thermal head 206 and the platen roller 208 in the conveyance path, as indicated by the dotted line in FIG. Here, the pressure roller 202 is disposed at the upper part of the conveyance path, and the pressure roller 204 is disposed at a position facing the pressure roller 202 at the lower part of the conveyance path. The first label 100-1 is pressed in the vertical direction by these pressing rollers 202 and 204. The microcapsule 114 mixed with the adhesive layer 110 is broken by this pressing force, and the internal repellent is released. When the pressing force by the thermal head 206 and the platen roller 208 is small, the microcapsule 114 may not be sufficiently destroyed. However, by providing the pressing rollers 202 and 204 in the printer 200-1 and increasing the pressing force, the microcapsules 114 can be reliably destroyed by the pressing rollers 202 and 204.

  Next, processing means for destroying the microcapsule 114 mixed in the adhesive layer 110 of the first label 100-1 by heating will be described. The thermal head 206 has a plurality of heating elements (not shown) as printing elements. These heat generating elements selectively generate heat according to the print data, and cause the print surface 117 of the print layer 116 of the first label 100-1 to thermally develop color. At this time, the microcapsule 114 mixed with the adhesive layer 110 is destroyed by heating and dissolution, and the internal repellent is released. Note that the printing method of the thermal head 206 is not limited to the thermosensitive coloring method, and may be any method that can heat and dissolve the microcapsule 114, and may be, for example, a thermal transfer method.

  Further, a heat source such as an electric heater may be provided inside the pressure rollers 202 and 204. In this case, the pressure rollers 202 and 204 are destroyed by heating and dissolving the microcapsule 114 in the first label 100-1 by an internal heat source, and the repellent inside the microcapsule 114 is diffused. In this way, by providing a heat source inside the pressure rollers 202 and 204, even if the microcapsule 114 is not sufficiently destroyed by the heat generated by the heating element in the thermal head 206, the microcapsule 114 can be reliably secured. It can be destroyed.

  The first label 100-1 on which information corresponding to the print data is printed is peeled off from the mount 102, and the adhesive layer 110 side is pressed against an object such as a resin film for packaging food. Thereby, the adhesive member 112 mixed with the adhesive layer 110 adheres to an object such as a resin film and is attached.

  Thus, the 1st label 100-1 consists of the adhesion layer 110 which mixed the microcapsule 114 which enclosed the repellent, and the printing layer 116 formed in the upper part of the said adhesion layer 110. FIG. When the first label 100-1 is heated or pressed during printing, the microcapsule 114 is destroyed and the repellent starts to diverge. Therefore, if the first label 100-1 is affixed to an object such as a resin film immediately after printing, in other words, if the first label 100-1 is used immediately after printing, the first label 100-1 is used. It becomes possible to exhibit the repellent effect of pests over a long period from the appropriate timing at the start of use of 100-1.

  By the way, in addition to the above-described first label 100-1, labels having various structures are conceivable. This will be described below.

  FIG. 3 is a diagram showing a manufacturing process of the second label in the embodiment of the present invention. In the first step shown in FIG. 3A, first, the adhesive layer 120 is formed. The adhesive layer 120 is formed by mixing a thermally activated adhesive member 122 and a microcapsule 124 enclosing a pest repellent, and corresponds to the microcapsule layer. The repellent contains, for example, plant-derived components such as lemon and chili as in the case of the first label 100-1.

  In the second step shown in FIG. 3B, as in the case of the manufacturing process of the first label 100-1, a printed layer 126 using paper, silicon, or the like as a member is formed on the adhesive layer 120. The upper surface of the printing layer 126 is a printing surface 127 on which various information is printed. Through such first and second steps, the second label 100-2 including the adhesive layer 120 and the print layer 126 is manufactured.

  FIG. 4 is a diagram illustrating a printing process of the second label 100-2 by the printer 200-2. When the printer 200-2 in FIG. 4 is compared with the printer 200-1 in FIG. 2, a thermal head 210 for thermal activation is newly disposed in the lower part of the conveyance path on the downstream side of the thermal head 206 and the platen roller 208. A platen roller 212 is disposed at a position facing the thermal head 210 in the upper part of the conveyance path.

  First, a method for destroying the microcapsule 124 mixed in the adhesive layer 120 of the second label 100-2 by pressing force will be described. The second label 100-2 is pressed in the vertical direction by the thermal head 206 and the platen roller 208 of the printer 200-2. Further, it is also pressed in the vertical direction by the thermal head 210 and the platen roller 212 for activating the adhesive layer 120 of the second label 100-2 by heating. By this pressing force, the microcapsules 114 mixed in the adhesive layer 120 are broken, and the internal repellent is diffused.

  Furthermore, the printer 200-2 may have a configuration in which the pressing rollers 202 and 204 are disposed on the downstream side or the upstream side of the thermal head 206 and the platen roller 208 in the conveyance path, as indicated by a dotted line in FIG. Here, the pressure roller 202 is disposed at the upper part of the conveyance path, and the pressure roller 204 is disposed at a position facing the pressure roller 202 at the lower part of the conveyance path. The second label 100-2 is pressed in the vertical direction by these pressing rollers 202 and 204. The microcapsule 124 mixed with the adhesive layer 120 is broken by this pressing force, and the internal repellent is released. When the pressing force by the thermal head 206 and the platen roller 208 or the thermal head 210 and the platen roller 212 is small, the microcapsule 124 may not be sufficiently broken. However, by providing the pressure rollers 202 and 204 in the printer 200-2 and increasing the pressure, the microcapsules 124 can be reliably destroyed by the pressure rollers 202 and 204.

  Next, processing means for destroying the microcapsules 124 mixed in the adhesive layer 120 of the second label 100-2 by heating will be described. The thermal head 206 has a plurality of heating elements (not shown) as printing elements. These heating elements selectively generate heat according to the print data, and cause the printing surface 127 of the printing layer 126 of the second label 100-2 to thermally develop color. At this time, the microcapsules 124 mixed in the adhesive layer 120 are destroyed by heating and dissolution, and the internal repellent is released. Note that the printing method of the thermal head 206 is not limited to the thermosensitive coloring method, and may be any method that can heat and dissolve the microcapsule 114, and may be, for example, a thermal transfer method. Further, the thermal head 210 can reliably destroy the microcapsule 124 by heating the adhesive layer 120 of the second label 100-2.

  Further, the pressure rollers 202 and 204 may be provided, and a heat source such as an electric heater may be provided inside the pressure rollers 202 and 204. In this case, the pressure rollers 202 and 204 are destroyed by heating and dissolving the microcapsules 124 in the second label 100-2 by an internal heat source, and the repellent inside the microcapsules 124 is diffused. As described above, by providing the heat source inside the pressure rollers 202 and 204, even if the microcapsule 124 is not sufficiently destroyed by the heat generated by the heating elements of the thermal head 206 and the thermal head 210, the microcapsule 124 is not destroyed. Can be reliably destroyed.

  In the second label 100-2 on which information corresponding to the print data is printed, the adhesive layer 120 side is pressed against an object such as a resin film for packaging food. As a result, the adhesive member 126 mixed in the adhesive layer 120 is adhered and attached to an object such as a resin film. Therefore, if the second label 100-2 is affixed to an object such as a resin film immediately after printing and thermal activation, in other words, if the second label 100-2 is used immediately, The pest repellent effect can be exerted over a long period from the appropriate timing of the start of use of the two-label 100-2.

  FIG. 5 is a diagram showing a manufacturing process of the third label in the embodiment of the present invention. In the first step shown in FIG. 5A, an adhesive layer 138 made of an adhesive member is formed on the upper surface of the mount 102. Next, in the second step shown in FIG. 5B, the protective layer 130 is formed on the adhesive layer 138. This protective layer 130 is formed by mixing a base material 132 and microcapsules 134 enclosing a pest repellent, and corresponds to the microcapsule layer. The repellent contains plant-derived components such as lemon and chili as in the case of the first label 100-1.

  In the third step shown in FIG. 5C, a printing layer 136 using paper, silicon or the like as a member is formed on the protective layer 130. The upper surface of the print layer 136 is a print surface 137 on which various information is printed. Through such first to third steps, the third label 100-3 including the adhesive layer 138, the protective layer 130, and the print layer 136 is manufactured.

  The third label 100-3 uses the printer 200-1 shown in FIG. 2 to reliably destroy the microcapsule 134 by heating or pressing, and the internal repellent is released.

  The third label 100-3 printed with information corresponding to the print data is printed by the printer 200-1, and after the microcapsule 134 is broken by heating or pressing, it adheres to an object such as a resin film that wraps food. Layer 138 is pressed. Thereby, the adhesive member which comprises the protective layer 130 adheres to objects, such as a resin film, and the 3rd label 100-3 is affixed on objects, such as a resin film.

  As described above, the third label 100-3 includes the adhesive layer 138, the protective layer 130 formed by mixing the microcapsules 134 encapsulating the repellent formed on the adhesive layer 138, and the upper part of the protective layer 130. The printing layer 136 is formed on the substrate. Similar to the first label 100-1, the third label 100-3 is heated or pressed at the time of printing, whereby the microcapsules 134 are broken and the repellent starts to be emitted. Therefore, if the third label 100-3 is affixed to an object such as a resin film immediately after printing, in other words, if the use of the third label 100-3 is started immediately after printing, the third label It becomes possible to exhibit the repellent effect of pests over a long period from the appropriate timing at the start of use of 100-3.

  FIG. 6 is a diagram showing a manufacturing process of the fourth label in the embodiment of the present invention. In the first step shown in FIG. 6A, first, an adhesive layer 148 is formed. Next, in the second step shown in FIG. 6B, a base layer 149 whose upper surface becomes a formation surface of a protective layer 140 described later is formed.

  In the third step shown in FIG. 6C, the protective layer 140 is formed on the base layer 149. The protective layer 140 is formed by mixing the base material 142 and the microcapsules 144 enclosing a pest repellent, and corresponds to the microcapsule layer. The repellent contains plant-derived components such as lemon and chili as in the case of the first label 100-1.

  In the third step shown in FIG. 6D, a printing layer 146 using paper, silicon or the like as a member is formed on the protective layer 140. The upper surface of the print layer 146 is a print surface 147, on which various information is printed. Through the first to fourth steps, the fourth label 100-4 including the adhesive layer 148, the base layer 149, the protective layer 140, and the print layer 146 is manufactured.

  The fourth label 100-4 uses the printer 200-1 shown in FIG. 2 to reliably destroy the microcapsule 144 by heating or pressing, and the internal repellent is released.

  The fourth label 100-4 on which information corresponding to the print data is printed is adhered to an object such as a resin film that wraps food after the microcapsule 144 is printed by the printer 200-1 and destroyed by heating or pressing. Layer 148 is pressed. Thereby, the adhesive member which comprises the adhesion layer 148 adhere | attaches on objects, such as a resin film, and the 4th label 100-4 is affixed on objects, such as a resin film.

  As described above, the fourth label 100-4 includes an adhesive layer 148, a base layer 149 formed on the adhesive layer 148, and a microcapsule encapsulating a repellent formed on the base layer 149. The protective layer 140 is a mixture of the protective layer 140 and the printed layer 146 formed on the protective layer 140. As with the first label 100-1, the fourth label 100-4 is heated or pressed at the time of printing, whereby the microcapsules 144 are destroyed and the repellent starts to be emitted. Therefore, if the fourth label 100-4 is affixed to an object such as a resin film immediately after printing, in other words, if the use of the fourth label 100-4 is started immediately after printing, the fourth label The pest repellent effect can be exerted over a long period from the appropriate timing at the start of use of 100-4.
