Description

  The present invention is a multi-display type miniature temperature sensitive label, and more specifically, it is possible to display a plurality of set temperatures with extremely small dimensions, and the same type of thermosensitive labels having different set temperature ranges can be easily displayed. The present invention relates to a multi-display type minimum temperature sensitive label that can be identified.

A temperature-sensitive label that uses the properties of petroleum-based wax and various chemical substances that dissolve at a preset temperature and irreversibly displays the fact that the set temperature has been exceeded is excellent in detection accuracy, low manufacturing cost, and mounting In recent years, it has been widely used in various industrial fields that require temperature management, such as power transmission and distribution facilities, railway facilities, and food manufacturing facilities.
None None

  In addition to the fact that a single temperature sensitive label indicates the fact that a single preset temperature is exceeded, as shown in FIG. 1, a plurality of preset temperatures such as 60 ° C., 70 ° C., 80 ° C. In addition, in order to display the temperature irreversibly, there is also a multi-display type temperature-sensitive label in which a plurality of temperature display portions 2 are formed on the surface of the base material 1. For finer temperature control, Needless to say, the multi-display type is more suitable. In the case of this multi-display type temperature-sensitive label, as shown in FIG. 1, a set temperature, for example, 60 ° C., 70 ° C., 80 ° C., or the like is attached in the vicinity of each temperature display portion 2 to set the set temperature. It is common to know how many times there is.

  On the other hand, there is a strong demand for downsizing of the temperature sensitive label, and it is also required to form a large number of temperature display portions having different set temperatures on the smallest possible substrate.

  The present applicant previously described in Japanese Patent Application Laid-Open No. 2006-29945, kneaded a petroleum wax powder, a thickener and a solvent that dissolves at a desired set temperature, and changes from opaque to transparent at the set temperature. Although we have proposed a thermal paint, it is possible to form multiple temperature display parts with different set temperatures on a very small substrate by using this temperature-sensitive paint. Although it is possible to minimize the temperature label, if the set temperature is added to each temperature display section as in the conventional multi-display type temperature-sensitive label, the temperature-sensitive label can be downsized due to its display space. Is naturally limited, and the excellent characteristics of the temperature-sensitive paint proposed in Japanese Patent Application Laid-Open No. 2006-29945 cannot be fully exhibited.

  Furthermore, for example, a temperature-sensitive label provided with a total of nine temperature display portions with different set temperatures every 45 ° C. from 45 ° C. to 85 ° C. and 5 ° C. from 90 ° C. to 130 ° C. on the substrate. A temperature-sensitive label with a total of nine temperature display sections with the same arrangement for each set temperature is difficult to distinguish because of the absence of a set temperature number (letter), making, storing, and moving This is because there is a possibility that the two may be mixed in the case of mounting and measurement, which is clearly not preferable in terms of product management. For this reason, an attempt has been made to distinguish the temperature-sensitive labels having different set temperature regions by changing the figure of the temperature display section for each set temperature. However, the temperature-sensitive paint proposed in JP-A-2006-29945 Because, the main material is oil-based wax powder, which has a strong repulsive force, if you try to draw a very small figure, the corners of the figure will be rounded, so you cannot draw a complicated figure, and the figure changes Attempts to show the difference in set temperature due to were not very practical.

  As a result of research conducted to realize minimization of a multi-display type temperature-sensitive label that has not been achieved so far, the present inventor has made use of the excellent characteristics of the temperature-sensitive paint proposed in Japanese Patent Application Laid-Open No. 2006-29945. The present inventors have succeeded in developing a multi-display type minimal temperature-sensitive label that can easily distinguish between temperature-sensitive labels having different set temperature regions.

  Preset by mixing petroleum-based wax powder, thickener and solvent on the surface of a rectangular base material with an adhesive layer formed on the back and black or desired color on the surface. The temperature consisting of one of the figures "○", "△", "□" that irreversibly displays the fact that the set temperature has been exceeded by the temperature-sensitive paint that changes irreversibly from opaque to transparent at the desired temperature. By forming a plurality of display portions at desired intervals to form a multi-display type minimal temperature-sensitive label, the above-described problems have been solved.

  This multi-display type minimal temperature-sensitive label is used for pasting the object to be temperature-controlled like the conventional temperature-sensitive label, and when the object reaches a preset temperature, The temperature display corresponding to the temperature changes from opaque to transparent, and the color of the surface of the substrate that was not visible until then can be seen, so this irreversible change visually knows the fact that the set temperature has been exceeded . On the other hand, this temperature-sensitive label is a multi-display type, and a large number of temperature display parts are formed on a single substrate. Each temperature display part has a number indicating how many times the set temperature is. (Character) is not displayed, but if you create a separate identification table showing the set temperature of each temperature display section, you can check the set temperature of each temperature display section easily and without error by collating with this I can do it.

  In addition, by changing the arrangement of each figure of “○”, “△”, and “□” forming each temperature display section according to common rules, it is possible to accurately distinguish the same temperature-sensitive labels having different set temperature ranges. Therefore, it is possible to minimize the multi-display type temperature-sensitive label without difficulty, and it has excellent practicality.

  The temperature display part is formed with each figure of “○”, “△”, “□”, and by adopting an arrangement method according to a certain rule, it is possible to clearly distinguish temperature-sensitive labels with different set temperature ranges. The biggest feature is in the point.

  2 to 4 are enlarged plan views of multi-display type minimum temperature-sensitive labels according to the present invention, each having a different set temperature region. In the figure, reference numeral 3 denotes a paper base material, and each side is 8 mm. However, it is possible to make it smaller, and it is of course not limited to 8 mm. The surface of the substrate 3 is given a color other than black or white. The color of the surface of the substrate 3 may be other than white, but dark colors such as black, blue, and red are preferable in order to make it easy to visually recognize changes in display when each set temperature is exceeded.

  On the surface of the base material 3, a temperature display unit 4 is formed by applying a temperature-sensitive paint obtained by kneading a petroleum wax powder that dissolves at a desired set temperature, a thickener, and a solvent. Has been. This temperature-sensitive paint is the same as that disclosed in JP-A-2006-29945. And this temperature display part 4 becomes any one figure of "(circle)", "(triangle | delta)", or "□", and it sets temperature of each temperature display part 4 by arrangement | positioning of these figures so that it may mention later. It is possible to know. The temperature display unit 4 can be formed by silk screen printing, letterpress printing, or other existing methods.

  Next, the arrangement of each figure of the temperature display unit 4 which is the eye of the present invention will be described. The temperature sensitive label shown in FIG. 2 has a set temperature range of 45 ° C. to 85 ° C. A total of nine temperature display portions 4 are formed every 5 ° C. up to 85 ° C., and the temperature display portion 4 (a) having a set temperature of 45 ° C. in the upper row position on the right column has a figure of “O”. The figure “Δ” is displayed on the temperature display section 4 (b) with a set temperature of 50 ° C. located immediately below it, and the temperature display section 4 (c) with a set temperature of 55 ° C. at the lower position in the right column is displayed. In the temperature display section 4 (d) where the set temperature is 60 ° C. in the upper row of the center row, the “△” figure is displayed, and the set temperature located immediately below it is the temperature display of 65 ° C. The part 4 (e) has a figure of “◯”, and the temperature display part 4 (f) at the lower position of the center row with a set temperature of 70 ° C. The figure “△” is displayed on the temperature display section 4 (g) whose set temperature is 75 ° C. at the upper left position of the left column, and the temperature display section 4 (h) set temperature just below it is 80 ° C. ) Is displayed with a graphic “◯”, and a temperature display 4 (i) with a set temperature of 85 ° C. at the lower position of the left column is displayed with a graphic “□”.

  On the other hand, the temperature-sensitive label shown in FIG. 3 has a set temperature range of 90 ° C. to 130 ° C., and “○” is displayed on the temperature display section 4 (j) at the set temperature of 90 ° C. in the upper row of the right column. The temperature display portion 4 (k) having a set temperature of 95 ° C. located immediately below it is marked with a “Δ” shape, and the temperature display portion 4 having a set temperature of 100 ° C. at the lower position of the right column is shown in FIG. l) has a figure of “Δ”, and the temperature display section 4 (m) at a set temperature of 105 ° C. at the upper position of the center row has a figure of “◯” at a set temperature of 110 just below it. The temperature display unit 4 (n) at 0 ° C. has a figure of “◯”, and the temperature display unit 4 (o) at a lower temperature setting of 115 ° C. has a figure of “O” at the upper left column. In the temperature display section 4 (p) where the set temperature is 120 ° C. at the position of “”, the figure of “Δ” is the temperature where the set temperature located immediately below is 125 ° C. Graphic radical 113 to 4 (q) "△" is, in the left column the lower temperature display set temperature of 130 ° C. at position 4 (r) is the figure of "□" are displayed.

Furthermore, the temperature-sensitive label shown in FIG. 4 has a set temperature range of 135 ° C. to 175 ° C.
The figure “◯” is displayed on the temperature display unit 4 (s) at the upper row position of the right column at 135 ° C., and the temperature display unit 4 (t) at the set temperature 140 ° C. located immediately below the temperature display unit 4 (s). In the temperature display section 4 (u) where the set temperature is 145 ° C. at the lower row position in the right row, the “△” shape is the temperature at which the set temperature is 150 ° C. at the upper row position in the center row. On the display unit 4 (v), a graphic “Δ” is located, and on the temperature display unit 4 (w), which is located immediately below the set temperature 155 ° C., a graphic “◯” is located at the lower position of the center row. A figure of “◯” is displayed on the temperature display section 4 (x) where the set temperature is 160 ° C., and a figure of “Δ” is displayed on the temperature display section 4 (y) where the set temperature is 165 ° C. at the upper position in the left column. The temperature display portion 4 (z) located immediately below it is 170 ° C., and a graphic “○” is shown, and the set temperature at the lower position of the left column is 175 ° C. The temperature display section 4 (α) is the figure of "□" are displayed, respectively.

  A common point of display in the temperature-sensitive labels shown in FIGS. 2 to 3 is a figure in which the lowest set temperature located on the upper right side is “◯” and the highest set temperature located on the lower left side is “□”. And a figure of “◯” is displayed in both the second row in the center row and the middle portion on the left side of the lower row. That is, in the temperature-sensitive labels shown in FIGS. 2 to 3, these temperature-sensitive labels are in different set temperature regions only due to the difference in orientation of the four “Δ” figures other than the common points. Are distinguished.

  Incidentally, the temperature-sensitive paint used for forming the temperature display portion 4 in the present invention contains petroleum wax powder having a strong repulsive force. Even if there is no problem with “○” and “□”, the portion is easy to collapse, but it is necessary to pay close attention to the formation of “△” whose corners are composed of acute angles. It is desirable to reduce the number as much as possible, and in the present invention, as described above, four “Δ” figures are sufficient.

  Of course, the arrangement of each figure is not limited to that shown in FIGS. 2 to 3, but each temperature display section from the lowest set temperature to the highest set temperature in each temperature sensitive label having a different set temperature range. 4 and the temperature display unit 4 indicating the lowest set temperature must be displayed in the same graphic, and the temperature display unit 4 indicating the highest set temperature in the other same graphic.

  This multi-display type minimal temperature-sensitive label is used for pasting the object to be temperature-controlled like the conventional temperature-sensitive label, and when the object reaches a preset temperature, As shown in FIG. 6, the temperature display portion corresponding to the temperature changes from opaque to transparent, and the color of the surface of the portion of the base material 3 that has not been seen so far can be seen, so this irreversible change. By this, the fact that the set temperature is exceeded can be known visually. In the example shown in FIG. 6, since the temperature display unit 4 indicating 45 ° C. and the temperature display unit 4 indicating 50 ° C. are both disappeared, the temperature of the object to which the temperature sensitive label is attached is 50 ° C. It is clear that it was reached.

  On the other hand, this temperature-sensitive label is a multi-display type, and a large number of temperature display parts 4 are formed on a single substrate 3, and how many times the set temperature is in each temperature display part 4? Is not displayed in numbers (characters), but as shown in FIG. 5, if an identification table 5 showing the set temperatures of each temperature display unit 4 is prepared separately, each temperature can be verified by collating it. The set temperature of the display unit 4 can be known easily and without error.

  In addition, if the temperature display portion 4 is formed using each of the figures “○”, “□”, and “△” in accordance with the above-mentioned rules, the use of “△” figures that are relatively difficult to form can be minimized. It is possible to manufacture a minimal temperature sensitive label efficiently.

  As described above, by changing the arrangement of the figures of “◯”, “□”, and “△” forming each temperature display unit 4 according to a common rule, the same temperature sensitivity with different set temperature ranges is obtained. It is possible to accurately distinguish the labels, and has the effect of being able to minimize the multi-display type temperature sensitive label without difficulty, and has excellent practicality.

  It can be used in all industrial fields that require temperature management, such as power transmission and transmission facilities, railway facilities, various factories, and product distribution industries.
