Definitions
- the present invention relates to a humidity indicator in which a color change effect of cobalt chloride according to a change in humidity can be used for determining humidity.
- a humidity determination surface where the cobalt chloride is exposed is provided on the surface of a humidity determination plate formed by holding cobalt chloride on a base paper, and the discoloration of the cobalt chloride on the humidity determination surface ( There is conventionally known a structure in which the humidity around the base paper can be visually determined by using a blue-pink color.
- Such a humidity indicator can be used for the transportation of various industrial products that dislike moisture (for example, electronic components such as circuit boards that may cause cracking due to moisture absorption of epoxy resin). It is used together with products and desiccants inside the packaging bag. That is, when the product is transported in such a state of use, it is possible to visually determine whether the humidity in the packaging bag does not exceed the specified limit based on the color of the humidity determination surface of the humidity indicator. It is a simple way to check whether the inside of a packaging bag containing a desiccant is kept in an appropriate humidity (dry state). For this reason, such humidity indicators are widely used in the electronics industry and the like. ing.
- both the front and back of the humidity judgment plate (and therefore the humidity judgment surface where cobalt chloride is exposed) are exposed to the outside, and the humidity judgment plate is directly hand-operated by the operator. I grabbed it and put it in and out of the dry pack.
- the humidity determination surface is exposed to the outside, so that the inside of the sealed storage container whose inside is kept in a low humidity state or the above-mentioned desiccant-containing packaging bag enters the atmosphere.
- the cobalt chloride on the humidity determination surface discolors relatively quickly due to direct contact with indoor air, causing the following problems. That is, when the humidity indicator is discolored in a relatively short time when the humidity indicator inside the packaging bag is opened and the inside humidity indicator is taken out, the operator may overlook the color before the discoloration and make an erroneous determination.
- the unused humidity indicator is taken out of the closed storage container and transferred to the above-mentioned packaging bag, if the discoloration occurs before the transfer due to the work delay, the user shall identify the humidity indicator as defective. Misunderstanding may cause various troubles.
- the base paper of the humidity indicator has been formed of filter paper (filter paper) or other paper.
- filter paper filter paper
- the fine dust paper (Dust, fibers, etc.) are likely to be generated, and if they adhere to electronic components, it may affect the performance. Therefore, it is desirable to prevent dust generated from the base paper from diffusing to the outside.
- the performance of electronic components may be affected by bringing other charged components or packaging materials close to them, and dust is more likely to adhere to charged components due to static electricity.
- the present invention has been made in view of the above-described circumstances, and has as its object to solve the conventional problems described above with a simple structure.
- At least one humidity at which the cobalt chloride is exposed is exposed on the surface of a humidity determination plate formed by holding cobalt chloride on a base paper.
- a first film that covers the surface of the humidity determination plate and a back surface of the determination plate are provided in a humidity indicator where a determination surface is provided, and the humidity determination can be performed by discoloration of cobalt chloride on the humidity determination surface.
- a second film at least Also, a flat air layer facing the entire surface of the humidity determination surface is formed between the first film and the surface of the humidity half-lj plate, and a plurality of small holes for directly communicating this air layer to the atmosphere are formed.
- a humidity indicator that is formed on the first film at intervals from each other is proposed.
- the first and second films are formed so as to protrude from an outer peripheral edge of the humidity determination plate, and A humidity indicator is proposed in which the outer peripheral portions of the films are directly joined to each other.
- the surface of the humidity determination plate has a plurality of humidity determination surfaces corresponding to a plurality of different humidity levels, respectively. Are arranged side by side at intervals, and the air layer is formed in common to the plurality of humidity determination surfaces, and a humidity indicator is proposed.
- the base paper is a hygroscopic filter paper
- the second film and the back surface of the humidity determination plate A flat second air layer facing at least a region corresponding to the humidity determination surface on the back surface is formed between the second air layer and a plurality of small holes that allow the second air layer to directly communicate with the atmosphere. Is formed on the second film at intervals from each other, and a humidity indicator is proposed.
- each of the films is subjected to an antistatic treatment. Evening is suggested.
- the front and back of the humidity determination plate are covered with the first and second films, even if the humidity indicator is directly picked by a worker by hand,
- the cobalt chloride on the humidity determination surface can be effectively prevented from adhering to the hands and extending into the body, and operators can handle the humidity indicator with peace of mind.
- fine dust paper debris, fiber, etc.
- the effect of dust on electronic components can be effectively prevented.
- a flat air layer is formed between the first film and the surface of the humidity determination plate so as to face the entire surface of the humidity determination surface, and a plurality of small holes for directly communicating this air layer to the atmosphere are formed in the first film. Since the humidity indicator is taken out from the closed storage container etc. into the atmosphere when the humidity indicator is taken out from the closed storage container etc., the humidity of the air layer is changed according to the humidity of the atmosphere. An appropriate time lag is ensured for the change, so that the elapsed time until the humidity determination surface changes its color (the time required for changing the color) can be set appropriately, which may occur if the time is relatively short.
- the length of the above-mentioned time lag (and thus the time required for discoloration) can be adjusted by appropriately setting the dispersion density and inner diameter of the above-mentioned plurality of small holes. Easy according to environment, etc. It is adjustable.
- the humidity determination surface is directly exposed to each of the small holes, only the cobalt corresponding to each small hole on the humidity determination surface is partially discolored, not only impairing the appearance but also performing the determination work.
- the humidity determination surface is not only a portion corresponding to the small hole but also the entire surface. Can be uniformly discolored, and the above problem can be solved.
- the first and second films are formed so as to protrude from the outer peripheral edge of the humidity determination plate, and the outer peripheral edges of the respective films are directly joined to each other. Therefore, the outer peripheral edge of the base paper can be completely covered with the first and second films, so that dust generation from the outer peripheral cut surface of the base paper can be reliably prevented, and the films can be directly bonded to each other. Since the joining operation can be performed relatively easily and reliably, the joining process can be simplified.
- a plurality of humidity determination surfaces are arranged on the surface of the humidity determination plate at intervals corresponding to a plurality of different humidity levels, respectively. Since the layer is formed in common for the plurality of humidity determination surfaces, the process for forming the air layer is simplified as compared with the case where the air layer is formed for each of the plurality of humidity determination surfaces.
- the base paper of the humidity determination plate is a filter paper having a hygroscopic property, and a space between the second film and the back surface of the humidity determination plate is provided between the second film and the back surface of the humidity determination plate.
- At least a flat second air layer facing an area corresponding to the humidity determination surface is formed, Since a plurality of small holes for directly communicating the second air layer with the atmosphere are formed in the second film at an interval from each other, when the humidity indicator is taken out of the closed storage container or the like into the atmosphere, The moisture in the atmosphere is transmitted from the back side of the base paper to the air layer on the front side through the inside of the base paper, so that the sensitivity of the humidity determination surface on the front side to a change in humidity can be further increased.
- the humidity judgment plate itself is hardly charged, and dust is hardly attached to the film due to static electricity.
- the influence of charging and dust on the electronic component can be minimized.

Approximately 10 to 1 on the second humidity judgment surface (limit humidity 10%) 5 minutes, about 20 to 25 minutes on the 3rd humidity judgment surface (limit humidity 20%), about 35 to 40 minutes on the 4th humidity judgment surface (limit humidity 30%), It can be seen that the product of this example has a longer time required for discoloration.
- the thicknesses of the air layers Au and Ad and the films F1 and F2 are slightly exaggerated from the actual scale for easy understanding.
- the humidity indicator I of the present embodiment is used for transporting electronic components such as circuit boards that do not like moisture, as shown in FIG. 4, inside the transparent airtight packaging bag DP with the electronic components E and desiccant D.
- the electronic components E are transported together with the packaging bag DP.
- a container with a tightly closed lid may be used instead of such a packaging bag.
- the humidity in the packaging bag DP is visually checked to see if it has exceeded the specified limit by the colors of the humidity judgment surfaces M1 to M4 (whether or not the color has changed) of the humidity indicator I. Since it is possible to judge, it is easy to check whether the inside of the packaging bag DP containing the desiccant D is kept in the proper humidity state (dry state) during transportation.

- a large number of small holes H ... that allow the air layer Au to directly communicate with the atmosphere are formed in the first film F1 at intervals. For this reason, when the humidity indicator I is taken out from the packaging bag DP or the like kept in a low humidity state into the atmosphere, an appropriate time lag occurs for the humidity of the air layer to change in accordance with the humidity of the atmosphere.
- the cobalt chloride Co on the humidity determination surfaces M1 to M4 can be prevented from discoloring in a relatively short time, that is, the elapsed time until the humidity determination surfaces M1 to M4 change color (color change required) Time) can be set appropriately without excess or deficiency, which is effective in preventing the occurrence of erroneous judgment / trouble due to, for example, a relatively short time.
- the length of the time lag (and thus the time required for discoloration) can be easily adjusted according to the purpose of use, working environment, etc., by appropriately setting the dispersion density and the inner diameter of the small holes H.
- each of the humidity determination surfaces M1 to M4 has There is a problem that only the cobalt chloride C 0 in the portion corresponding to the holes H is partially discolored, which not only impairs the appearance but also makes it difficult to perform the judgment work.
- the entire surface of the humidity determination surfaces M1 to M4 not only the portions corresponding to the small holes, also discolors uniformly. The above problem can be solved.
- the first and second films F 1 and F 2 are formed so as to protrude from the outer peripheral edge of the humidity determination plate P, and the outer peripheral edges F la and F 2 of the respective films F 1 and F 2. a Directly joined to each other m. For this reason, since the outer peripheral edge of the base paper B can be completely covered with the first and second films F 1 and F 2, the generation of dust from the outer peripheral cut surface of the base paper B can be reliably prevented. Direct joining between Fl and F2 can be performed relatively easily and reliably, so that the process can be simplified.
- a flat backside air layer Ad is formed that faces at least the region corresponding to the humidity determination surfaces M1 to M4 on the back surface.
- the two films F2 are formed at an interval from each other. Therefore, when the humidity indicator is discharged into the atmosphere from the packaging bag DP or the like, the humidity in the atmosphere is transferred from the back side of the base paper B to the back air layer Ad and the front air layer through the base paper B. It is also transmitted to Au, so that the sensitivity of the front-side humidity determination surfaces M1 to M4 to changes in humidity can be further increased.
- M4 is shown as being vertically and horizontally arranged on the surface of base paper B, in the present invention, the limit humidity, number, arrangement, shape, etc. of the humidity determination surface are arbitrary, and are limited to those of the above-described embodiment. Not done.
