Description

The present invention relates to a method for regenerating a decorative body and a humidifier.

In a room, a decorative body is known in which crystals of a crystalline inorganic salt are precipitated at the end of a water-absorbent base material having a three-dimensional shape and used for decoration as if it were a cherry blossom or a Christmas tree. This decorative body is used as a decorative body by immersing the base end of a water-absorbent base material having a three-dimensional shape in an aqueous solution of a crystalline inorganic salt to suck up water, and precipitating crystals of the inorganic salt at the upper end of the base material. (Patent Documents 1 to 3). The shape and amount of crystals differ slightly depending on the temperature and humidity conditions when the crystals precipitate, and the crystals are colored when a dye is used, but the degree of coloring also differs depending on the temperature and humidity conditions, so the crystals are exactly the same. It does not become. However, after the crystals are deposited, they are viewed in that form until the crystals are scattered.

However, the crystalline inorganic salt deposited on the decorative body is relatively easily removed by vibration or contact, and the appearance of the decorative body is deteriorated. The crystals that have fallen off cannot be attached to the ornament again and remain at their disposal. Moreover, since it is a crystal, it is difficult to improve the adhesiveness. A method of prolonging the life of the ornament is desired. On the other hand, there is also a request that crystals of slightly different colors and shapes can be viewed many times with the same decorative body.

Hereinafter, embodiments of the present invention will be described in detail. The present invention is not limited to the following embodiments. Within the same and equal scope as the present invention, various modifications can be made to the following embodiments.

1. 1. Decorative body First, the decorative body applied to the present invention will be described.
In the decorative body of the present invention, a three-dimensionally shaped base material having water absorption, an aqueous solution in which a crystalline inorganic salt is dissolved, and a base end portion of the water-absorbent base material can be installed to fill the aqueous solution. It consists of a container. The method for producing a decorative body using the above-mentioned three-dimensionally shaped paper base material is a conventionally known method, that is, the base end portion of the three-dimensionally shaped base material having water absorption in an aqueous solution of a crystalline inorganic salt. It is possible to obtain a decorative body by immersing it in water and sucking up water to precipitate crystals of an inorganic salt on the upper end of the base material.

(Three-dimensional shaped base material with water absorption)
The three-dimensionally shaped base material having water absorption means a base material having a three-dimensionally shaped skeleton in which crystals are precipitated to form a decorative body. The material of the water-absorbent base material (hereinafter, may be simply referred to as a water-absorbent base material or simply a base material) that forms a three-dimensional shape is not particularly limited as long as it has water absorbency and shape retention, but paper. Is preferable because of its versatility. The type of paper is not particularly limited as long as it is a paper that absorbs water and precipitates crystals of crystalline inorganic salts at the upper end of the base material, but for example, an absorbent paper material such as filter paper or coaster base paper is used. Is preferable. The thickness of the base material is preferably such that the three-dimensional shape can be maintained even if crystals are deposited. The size of the base material is not particularly limited as long as the aqueous solution is sucked up and the crystals are sufficiently precipitated, and may be determined according to the purpose, but the height is preferably 30 cm or less.

The shape of the three-dimensional base material having water absorption is not particularly limited, and examples thereof include those formed of flowers, trees, animals, buildings, and the like. The base material having a three-dimensional shape is formed by combining one or two or four pieces of cut paper to form a skeleton having a desired shape. For example, those described in Japanese Patent Application No. 2021-941744 and Japanese Patent Application No. 2021-192040 can be used.

(Aqueous solution in which crystalline inorganic salt is dissolved)
The crystalline inorganic salt used in the aqueous solution is not particularly limited as long as crystals are precipitated at the tip of the substrate, and for example, sodium acetate, monopotassium phosphate, monoammonium phosphate, monocalcium phosphate, and ammonium nitrate. And so on. Of these, at least one or more can be used. Preferred are sodium acetate and monopotassium phosphate.
Further crystalline sodium chloride, potassium chloride, calcium chloride, ammonium chloride and the like may be added to the aqueous solution as needed. These inorganic salts are also included in the crystalline inorganic salts in the present invention.

The amount of the crystalline inorganic salt in the aqueous solution is used within the saturation concentration range, but the concentration of the crystalline inorganic salt in the aqueous solution is preferably 30% or more and 96% or less of the saturated concentration of the crystalline inorganic salt. .. More preferably, it is 50% or more and 90% or less. If it is 30% or more, crystals can be sufficiently precipitated at the end of the base material. If it is 96% or less, crystals are unlikely to precipitate in an aqueous solution even in a low temperature state close to 0 ° C. When different types of crystalline inorganic salts are mixed, it is preferable that the concentration of the main crystalline inorganic salt is in the above range.

An inorganic acid and / or an organic acid can be further mixed in the aqueous solution in which the crystalline inorganic salt is dissolved to increase the crystal content of the final inorganic salt.
Examples of the inorganic acid include hydrochloric acid, nitric acid, sulfuric acid, phosphoric acid, boric acid and the like. Examples of the organic acid include formic acid, acetic acid, succinic acid, citric acid, tartaric acid, glycolic acid, malic acid and the like. Organic acids are preferred. Particularly preferred are organic carboxylic acids such as succinic acid, citric acid, tartaric acid, glycolic acid and malic acid.

The amount of the inorganic acid and / or the organic acid (hereinafter, may be simply referred to as an acid) is preferably 0.001 mol or more and 3.0 mol or less with respect to 1 mol of the crystalline inorganic salt. More preferably, it is 0.01 mol or more and 1.0 mol or less. If it is 0.001 mol or more, it can be clearly confirmed that crystals of the crystalline inorganic salt are deposited at the end of the substrate, and if it is 3.0 mol or less, it is economical. The acid may be added to the aqueous solution as it is, or it may be diluted 5 to 20 times and added. The latter is preferable in that the amount can be accurately added.

A fragrance may be added to the aqueous solution. As the fragrance, for example, geraniol, citral, terpineol, l-menthol, linalool, limonene and the like can be used. These can be emulsified and dispersed or solubilized in water with a water-soluble solvent such as ethanol or a surfactant.

(container)
The container used for the decorative body kit may have a space formed at the bottom to fill an aqueous solution in which a crystalline inorganic salt is dissolved. Conventionally, there are two pieces of paper, and if crystals are deposited at the ends, they may fall down. Therefore, the base material is supported in a stable state, for example, a cross-shaped notch at the bottom for inserting the base material. Containers with a certain structure have been used. In the case of a base material that can stand on its own, it is sufficient that a space filled with an aqueous solution in which a crystalline inorganic salt is dissolved is formed at the bottom, and a special container as in the conventional case is not required. The shape of the bottom of the container is not particularly limited to a rectangular plate such as a square, and may be circular or elliptical.

The material of the container is not limited as long as it can stably hold the aqueous solution in which the crystalline inorganic salt is dissolved, and examples thereof include plastic, glass, and stainless steel. The size of the container, the depth of the space filled with the aqueous solution, etc. may be determined by the size of the base material, the amount of the aqueous solution, and the like.

The above-mentioned piece of paper may contain a crystalline inorganic salt. If a piece of paper, that is, a base material is impregnated with a crystalline inorganic salt in advance, the absorption rate of the aqueous inorganic salt solution becomes faster and the crystals become significantly faster than before, as described in JP-A-2021-282050. Can precipitate. In addition, it is possible to improve the rising height of the aqueous solution in paper due to the capillary phenomenon.

Further, it is preferable that the piece of paper contains a specific dye. When a piece of paper contains a dye, the crystalline inorganic salt is attracted and moved as it moves to the end of the substrate, so that the crystal can contain the dye. Then the crystals look as if they were dyed. Crystals of different colors can be obtained by using dyes of different colors. And you can enjoy the colorful crystals.

As such a dye, a dye that is water-soluble and does not easily react with a piece of paper is preferable. If the dye is water soluble, it tends to be more or less like that. As the dye, a cationic dye or the like can be used, but an acid dye containing a Na sulphonate group, a Na carboxylate group, or an anionic dye such as a direct dye is preferable. Particularly preferred are dyes used for food dyes with low reactivity. If it is an edible pigment, it is safe even if it enters the mouth together with crystals, which is preferable in actual use.

As a method of impregnating the piece of paper with the dye, the piece of paper may be impregnated by immersing it in an aqueous solution of the dye, or the aqueous solution of the dye may be sprayed and applied, and then dried. The dye content in a piece of paper can also be controlled by changing the dye concentration of the dye aqueous solution.

The processing temperature of the piece of paper is preferably room temperature to 50 ° C. The drying temperature is preferably room temperature drying or 50 ° C. Even when an aqueous solution of a crystalline inorganic salt is prepared, the concentration of the crystalline inorganic salt in the aqueous solution is preferably 0.01% by mass or more and 5.0% by mass or less. More preferably, it is 0.1% by mass or more and 2.5% by mass or less.

As a method for producing a decorative body, a base material may be placed in a container at room temperature, and an aqueous solution in which a crystalline inorganic salt is dissolved may be placed in the container. The aqueous solution is absorbed by the base material by capillarity, and crystals begin to precipitate from the tip of the base material. The crystals continue to precipitate for a while even after all the aqueous solution in the container is absorbed. Although it depends on the size of the substrate, it usually takes 5 to 10 hours for the crystals to completely precipitate.
As described above, a decorative body in which crystals are precipitated at the ends of the substrate can be produced.

2. 2. Regeneration method The method for regenerating a decorative body in the present invention is the step A of removing the crystals of the crystalline inorganic salt deposited on the decorative body, and the crystals of the removed crystalline inorganic salt are dissolved in water to form an aqueous solution. Step B, the step C of immersing the base of the decorative body from which the crystals of the crystalline inorganic salt have been removed in the aqueous solution is included in this order, and the crystalline inorganic salt is again attached to the end of the three-dimensionally shaped substrate having water absorption. It is a method of regenerating a decorative body that precipitates crystals of.

In the present invention, the term "regeneration" means that the amount of crystals becomes 80% or more of the initial amount of crystals when the crystals are precipitated again. It is preferably 90% or more, and particularly preferably 95% or more. The most preferable is 100% or more. 100% or more means that the amount of crystals after the first is larger than the amount of crystals at the beginning.

When regenerating, use water. When creating a decorative body, an aqueous solution impregnating with an inorganic salt is used, but when regenerating it thereafter, it is usually preferable to use only water. Common sense is that you have to add inorganic salt and start over, but we found that you can do it only with water.

To remove the crystals of the crystalline inorganic salt in the step A, the crystals deposited on the decorative body are mechanically dropped, water is poured from the top of the decorative body to drop the crystals into the container, and water is put into the container to cause a capillary phenomenon. It is possible to suck up water and dissolve the gradually precipitated crystals, but there is no particular limitation.

Step B is linked to Step A, but when the crystals of the crystalline inorganic salt in Step B are dissolved in water to make an aqueous solution, the dropped crystals are dissolved in water, and water is sprinkled over the decorative body. Examples include dropping it into a container to make it an aqueous solution, putting water in the container, sucking up the water by the capillary phenomenon, dissolving the gradually precipitated crystals, and dropping it into the container to make an aqueous solution. Either method may be used.

The present invention is the method of using the decorative body according to claim 1, further comprising repeating step A, step B, and step C a plurality of times.
The plurality of times is 2 times or more, preferably 3 times or more, and particularly preferably 5 times or more. The larger the number of repetitions, the more preferable, but as the number of repetitions increases, the amount of crystals gradually decreases.

The number of regenerations can be controlled by selecting the type and amount of acid when producing the first ornament. In this case, an organic carboxylic acid is preferable, and an inorganic acid may be used in combination, but only an organic carboxylic acid is preferable. Examples of the organic carboxylic acid include those described in the section of decoration. The amount of the organic carboxylic acid is preferably 0.001 mol or more and 0.5 mol or less with respect to 1 mol of the crystalline inorganic salt. More preferably, it is 0.002 mol or more and 0.1 mol or less. If it is 0.001 mol or more, it can be clearly confirmed that crystals of the crystalline inorganic salt are precipitated at the end of the substrate multiple times, and if it is 0.5 mol or less, it is economical.

Further, as the regeneration is repeated, a hard inorganic salt (not a crystal) adheres to the surface of the paper, the precipitated crystal becomes hard, and the amount of precipitation decreases. In that case, the crystals are dropped from the decorative body, immersed in water to dissolve the hard crystals or the inorganic salt in the paper in water, and dried, so that the crystals are deposited at the ends again. In that case, the above-mentioned inorganic salt can be supplemented by putting it in water.

In this way, the reproduction can be repeated and enjoyed many times. In crystal precipitation, the crystal shape, amount of crystals, color, etc. change slightly depending on the temperature and humidity conditions, air convection, etc., and you can enjoy the changes.
Depending on the amount of water added, the appearance of crystals and colors will change, and you can enjoy different scenery each time you regenerate.
Further, when a substrate in which crystals of different colors are precipitated is combined and the above reproduction is repeated, the hue gradually changes, and it is possible to enjoy how the color changes slightly with each repetition.

3. 3. Humidifier The humidifier of the present invention comprises a decorative body in which crystalline inorganic salts are deposited, a container that houses the decorative body and fills with water, and water contained in the container, and is deposited on the decorative body. It is a humidifier characterized by evaporating water from crystals of crystalline inorganic salts.

In the humidifier of the present invention, the decorative body sucks up the water in the container and evaporates the water from the crystals or the base material deposited at the end, and can raise the humidity around the crystal or the base material. The humidifier of the present invention has become possible by using the above-mentioned regeneration method.
If you have created a decorative body with crystals deposited in the container, you only need to add water. When water is added, the precipitated crystals collapse, but further crystals precipitate to form a decorative body. If the crystals remain moist, the crystals will not collapse and the water will evaporate as they are. When the water in the container is exhausted and the crystals are in a dry state, if water is put into the container, the crystals will collapse when the water is absorbed. By selecting the time to add water in this way, it is decided whether to regenerate the crystal or to use the decorative body as it is. You can humidify while enjoying the regeneration of the decoration.

As a simple humidifier that does not use electricity, a humidifier that uses water-absorbing paper is known. Some water-absorbent papers are decorative, but they do not move and maintain the same shape. In the case of the humidifier of the present invention, crystals can be precipitated, disappeared, and repeated, and the evaporation rate of water does not change, so that the humidifier has a dynamic ornament.

Hereinafter, the present invention will be further described with reference to Examples, but the present invention is not limited thereto.

(Production Example 1) (Production of an aqueous solution of a crystalline inorganic salt)
In a 200 mL beaker, 18.6 g of monopotassium phosphate, 0.8 g of sodium chloride and 0.8 g of 10 wt% aqueous solution of "PEG1000" (polyethylene glycol, number average molecular weight 1000), 5 g of 1 wt% aqueous solution of succinic acid, citric acid. 5 g of a 1 wt% aqueous solution of the above and 69.8 g of water were added and stirred at room temperature for 1 hour with a stirrer to dissolve the solid substance to obtain an aqueous solution of a colorless transparent liquid crystalline inorganic salt.

(Production Example 2) (Production of an aqueous dye solution containing a crystalline inorganic salt and a dye)
To a 100 ml beaker, add 0.2 g of monopotassium phosphate, which is a crystalline inorganic salt, and 1 g of a 1% by mass aqueous solution of Red No. 106 (edible dye) to 20 g of water, and stir for 3 hours with a stirrer at room temperature to create a red transparent liquid. An aqueous dye solution containing a crystalline inorganic salt and a dye was obtained.

(Example 1)
Using a coaster base paper (thickness 0.8 mm), cut a piece of water-absorbent paper that forms a three-dimensional shape into a tree shape (height 8 cm, width 5.2 cm), and then cut it from the end so that it becomes a branch. Then, when combined, it was created so that it would have a shape showing a tree. I made 3 of these. This piece of paper is immersed in the above dye aqueous solution for 30 minutes, taken out, left at room temperature for 30 minutes, placed in a dryer at 37 ° C. and dried for 1 hour, and three pieces of water-absorbent paper containing a crystalline inorganic salt. Got A base material for a decorative body was prepared by combining three pieces of paper. The base material for a decorative body is shown in FIG.

An acrylic square container (8 cm × 8 cm × height 4 cm) was prepared in a room at 25 ° C., and 15 g of the aqueous solution produced in Production Example 1 was poured into the room. The substrate formed as described above was placed upright in this liquid. Immediately the liquid began to penetrate from the root. The temperature in the room was 20 ° C., and the air conditioning equipment was operated to circulate the air in the room. After about 6 hours, a cherry-like ornament was obtained in which the entire tree was covered with pink inorganic salt crystals, as shown in FIG.
FIG. 2 is a photograph showing a decorative body according to an embodiment of the present invention. When the same ornament was prepared, crystals were dropped and the amount of crystals was measured, the amount of crystals was 2.12 g.

Regeneration methods and dehumidifiers were evaluated using different ornaments.
Further, 50 g of water was placed in a square container containing a decorative body (Example 1). For comparison, a three-dimensional decorative base material was similarly prepared using the same three base materials as the base material used as the decorative body, placed in a quadrangular container, and 50 g of water was added (Comparative Example 1). .. Further, only 50 g of water was put into the square container without putting the base material (Comparative Example 2). These were left indoors and the rate of evaporation of water was investigated. This result is shown in FIG. FIG. 3 is a graph showing the evaporation rate of water.

It can be seen that the evaporation rate of water in the container containing the decoration is almost the same as that in the case of only the base material, and the evaporation rate of water does not decrease even by the precipitation of crystals. In addition, it was confirmed that the water evaporates much faster than when only water is added, and that it has the performance as a humidifier.

After the water had evaporated from the container, the same operation was performed 7 times by adding 50 g of water again. The crystals of the decorative body collapsed each time water was added, and then new crystals were precipitated to form a similar decorative body. A photograph of the decorative body after 7 times is shown in FIG. When the crystal amount was measured by dropping the crystals after 7 times, the crystal amount was 2.13 g. 100% of the initial amount of crystals was precipitated as crystals.
It was also confirmed that the evaporation rate of water at the 7th time was the same as that at the 1st time.
It was confirmed that it is also effective as a humidifier having the regeneration method of the present invention and a dynamic decorative body.
