Description

The present invention relates to a bag.

Conventional pocket warmers can be broadly divided into those that use the heat of reaction generated by an oxidation-reduction reaction that occurs between iron powder and activated charcoal in salt water, and those that use far-infrared radiation generated by exciting the crystalline water contained in salt crystals using a microwave oven or similar device. However, the former have the problem of low-temperature burns due to sudden chemical reactions, and require special care when used by the elderly, disabled, infants, diabetics, etc. Furthermore, many of them are disposable, which is uneconomical, wastes resources, and has the problem of lacking diversity.

A thermal insulation device has been disclosed (Patent Document 1) in which a thermal insulation material made by adding glycerin, montmorillonite, calcium carbonate, and salt is wrapped in one or more films such as polyethylene, polyvinyl chloride, and polyvinyl acetate, and placed on parts of the body that dissipate heat to prevent heat from dissipating from those parts. However, this thermal insulation device uses the heat emitted by the user as its heat source and is not intended to be used as a souvenir.

A far-infrared heating zone has been disclosed that contains rock salt as a hygroscopic heating substance and gravel made of granular porous andesite and basalt, the main component of which is silicon, as a far-infrared emitting substance (Patent Document 2). However, this far-infrared heating zone uses special gravel called silica high gray, and does not use waste-derived or naturally-derived aluminosilicate-containing components selected from sea sand, crushed ceramics, or jewel waste.

AdverTimes column, "The true meaning of 'From things to experiences' - What is behind experience branding (part 2)" (URL: https://www.advertimes.com/20180406/article266418/)

However, unlike the era when the products described above in the background art were proposed, today's everyday items require a new perspective, such as an attitude that faces the wide variety of social issues that have recently become apparent and selling experiences rather than things. Pocket warmers are no exception, and they are intended to be a way of empathizing with the feelings of those who purchase the product, evoking memories, providing healing, and giving a momentary sense of happiness, for example, from the perspective of effectively utilizing industrial waste materials, cultivating compassion and mercy for the elderly and infants, recalling travels and hometowns, and providing an opportunity to remember loved ones or pets who have passed away (Non-Patent Document 1). Without these perspectives, future consumer behavior will be insufficiently understood, and the industry cannot be expected to develop.

Conventional pocket warmers are completely lacking in the ability to address the wide variety of social issues that have recently become apparent, and in the ability to empathize with people's feelings.

In light of the current situation as described above, the present invention aims to provide a keepsake composition that provides a suitable amount of warmth that fits the body and maintains that warmth for a long period of time, and more preferably a keepsake composition that is in tune with the user's feelings, evokes memories, provides healing, and gives a momentary sense of happiness, as well as a keepsake and a method for using the same.

One aspect of the present invention made to achieve the above object is a composition for a commemorative item containing sodium chloride and one or more waste-, natural- or animal-derived materials selected from waste-, natural- or animal-derived silicate-containing components, waste-, natural- or animal-derived aluminosilicate-containing components selected from sea sand, crushed ceramics or jewel waste, waste-, natural- or animal-derived calcium carbonate-containing components, and waste-, natural- or animal-derived calcium phosphate-containing components. According to the above configuration, by using waste-, natural- or animal-derived materials, the perspectives of effective use of waste materials, memorialization of deceased people or pets, and shaping memories of travels or hometowns can be incorporated into the commemorative item, which can evoke memories, provide healing, and give a momentary sense of happiness. In addition, by selecting or appropriately combining one or more of the above waste-derived, natural-derived, or animal-derived materials, the temperature immediately after heating and the resistance to cooling can be adjusted according to the material and thickness of the bag used for the outer cover, so that a keepsake that is moderately warm and fits the body and maintains its warmth for a long time can be obtained, and it can also be used at home when sleeping. In this specification, the outer cover refers to anything that surrounds the composition, and is not limited to the outer bag, but is a term that refers comprehensively to non-permeable bags and permeable materials.

In the above-mentioned souvenir composition, the sodium chloride is preferably a salt derived from seawater. Salt derived from seawater generally has a high water content, and therefore tends to become hot immediately after being removed from a microwave oven or heater.

The above-mentioned souvenir composition preferably contains 70 to 85% by weight of sodium chloride and 15 to 30% by weight in total of one or more waste-derived, natural or animal-derived materials based on the total weight of the composition. If the composition is within the above range, the temperature immediately after removal from the microwave oven or heater will not become too high, and the composition will not cool down easily.

Another aspect of the present invention, which has been made to achieve the above object, is a keepsake in which the above-mentioned keepsake composition is wrapped in a water-permeable material. Water can be slowly supplied to the composition through the water-permeable material, making the keepsake suitable for repeated use.

The above-mentioned commemorative item is preferably stored in a sealable, water-impermeable bag. If the pocket warmer wrapped in a water-permeable material is sprayed with water while it is inside the water-impermeable bag, the surrounding area will not get wet and it is easy to manage. In addition, spraying an excess amount of water allows the excess water to permeate and replenish the water-permeable material as appropriate, maintaining the properties of the pocket warmer, and the bag can be sealed so that water does not leak out.

The commemorative item is preferably the sealable, water-impermeable bag housed in an outer bag. Since fewer functional characteristics are required of the outer bag, there are more variations available, making it possible to give the item a cute, eye-catching, and fashionable appearance. Also, by changing the material and thickness of the outer bag, the perceived temperature can be lowered or raised.

It is preferable that the souvenir has a heat-retaining material between the outer bag and the sealable water-impermeable bag, as this will help maintain the warming effect.

Another aspect of the present invention, which has been made to achieve the above object, is a method of using the keepsake, which includes spraying water on the surface of the keepsake so that the center does not become wet, and heating or keeping warm in a microwave oven or heater. This prevents the deep temperature from reaching a plateau near the boiling point of water, and allows the temperature to be raised to 100°C or higher immediately after removal from the microwave oven or heater, so that the warming effect can be maintained for a long time even if the composition has the property of cooling somewhat easily.

The method of using the commemorative item preferably involves spraying water evenly, in an amount of 0.5 to 5% by weight based on the total weight of the composition for the commemorative item. If the amount of water sprayed is within the above range, even if the commemorative item contains a composition whose properties have deteriorated due to repeated use, the property of having a temperature of 100°C or higher immediately after being removed from a microwave oven or heater can be immediately restored, and the commemorative item can be used repeatedly about two to three times.

Another aspect of the present invention, which has been made to achieve the above object, is a keepsake composition that contains, relative to the total weight of the composition, 70 to 85% by weight of sodium chloride and 15 to 30% by weight in total of one or more components selected from calcium carbonate, calcium phosphate, and silicates. With the above composition, the keepsake composition becomes one that feels just the right amount of warmth on the body and maintains that warmth for a long period of time.

Another aspect of the present invention, which has been made to achieve the above object, is a commemorative item that is made by adding water and starch glue to the above-mentioned composition for commemorative items, mixing and shaping it. This commemorative item dissolves easily when placed in water, leaving no residue. In addition, if the ingredients are naturally derived, it will not pollute the environment even if it dissolves.

Another aspect of the present invention, which has been made to achieve the above object, is a souvenir in which the above-mentioned souvenir composition is stored in a bag. This souvenir can be used as a talisman, for example, after appropriate purification or other treatment.

Another aspect of the present invention, which has been made to achieve the above object, is a multi-layered warming pocket warmer in which one or more waste-, natural- or animal-derived materials selected from waste-, natural- or animal-derived silicate-containing components, waste-, natural- or animal-derived aluminosilicate-containing components selected from sea sand, crushed ceramics or gemstone waste, waste-, natural- or animal-derived calcium carbonate-containing components, and waste-, natural- or animal-derived calcium phosphate-containing components are surrounded by a heat-resistant material and sandwiched between the above-mentioned keepsake. When arranged in layers in this way, the heat storage effect of the waste-, natural- or animal-derived materials allows the warmth to last for a long time.

The above heat-resistant material is preferably carbonized fiber, carbon fiber, aluminum fiber, urethane rubber, glass fiber sheet, composite material of silicone rubber and linen cloth, silicone rubber, composite material of silicone rubber and aramid fiber sheet, or polyester sheet from the viewpoint of preventing scorching.

According to the present invention, by incorporating the perspectives of making effective use of waste materials, memorializing deceased people or pets, and giving shape to memories of travels or hometowns into souvenirs, the souvenirs can empathize with the user's thoughts, evoke memories, provide healing, and give a momentary sense of happiness. In addition, according to the souvenir composition and souvenirs and their methods of use of the present invention, the temperature immediately after heating is not too high and the heat retention is relatively high, preventing low-temperature burns and allowing the souvenirs to be used at home while sleeping.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.
The composition for a souvenir according to the present invention includes sodium chloride and one or more waste-derived, natural-derived or animal-derived materials. In this specification, the term "souvenir composition" refers to a composition used for a souvenir. In this specification, the term "souvenir" refers to an item that is close to the user's thoughts, evokes memories, heals, and gives a momentary sense of happiness. Examples of such items include items that are used as souvenirs at travel destinations, items that contain special products from travel destinations or hometowns, and items that contain ingredients derived from humans or animals that have some kind of connection, regardless of whether they are related by blood or not, and these include warm pocket warmers, amulets, and sculptures. In this specification, unless otherwise specified, the term warm pocket warmer includes a multi-layer warm pocket warmer that combines two or more warm pocket warmers.

The sodium chloride may be either rock salt or salt derived from seawater, but it is more preferable that it contains moisture equivalent to about 1% humidity by weight. Salt derived from seawater is preferably used, and examples of such salt include those commercially available as solar salt, heavenly salt, and coarse salt. Note that salt derived from seawater may contain trace amounts of bittern components and impurities. Sodium chloride with a porosity of about 50% to 90% and high bulk is preferably used. The preferred range for the angle of repose of sodium chloride is 40° to 70°.

As one or more waste-derived, natural or animal-derived materials, for example, one or more selected from the group consisting of waste-derived, natural or animal-derived silicate-containing components such as seagrass, silica sand, quartz, etc., waste-derived or natural aluminosilicate-containing components selected from beach sand (sea sand) from around the world or Japan, crushed ceramics or rubbish gemstones, waste-derived, natural or animal-derived porous or non-porous calcium carbonate-containing components such as coral sand, coral fragments, shells, rubbish (true) pearls, pearl powder, etc., and waste-derived, natural or animal-derived calcium phosphate-containing components such as human or animal bones (powder), teeth (powder), horns (powder), etc. can be selected and mixed and used. In this specification, the aluminosilicate-containing component is a component containing a compound having a structure in which some of the silicon atoms in a silicate are replaced with aluminum atoms, and is conceptually distinguished from the silicate-containing component. However, the silicate-containing component may contain a small amount of aluminum to the extent that it does not affect the composition formula.

When the souvenir composition according to the present invention is used in a heated pocket warmer, it is preferable that the composition contains 70 to 85% by weight of sodium chloride and 15 to 30% by weight of one or more waste-derived, natural or animal-derived materials based on the total weight of the composition. A more preferable lower limit of sodium chloride is 73% by weight.

The souvenir composition according to the present invention, particularly when used for a shaped object, preferably contains 70 to 93% by weight of sodium chloride and 7 to 30% by weight of one or more waste-derived, natural or animal-derived materials relative to the total weight of the composition. A more preferred lower limit for sodium chloride is 80% by weight. A more preferred upper limit for one or more waste-derived, natural or animal-derived materials is 20% by weight.

Specific combinations of components for the souvenir composition of the present invention are not particularly limited, and include salt/coral flakes/coral sand, salt/coral sand/bone powder (bone ash), salt/quartz/bone powder, salt/seagrass/shell powder/bone powder, salt/pearl powder/coral sand, salt/coral sand/silica sand, salt/coral sand/silica sand/bone powder, salt/jewelry dust, etc., and from the viewpoint of water retention and heat retention, a two-component composition, a three-component composition, or a four-component composition containing salt and coral sand is preferred.

The porosity of sodium chloride and one or more waste-derived, natural, or animal-derived materials can be said to be an index of the content of air layers with low thermal conductivity, but when spraying water and heating it, the heat stored in the water has a greater effect on heat retention, so it does not have much effect on heat retention. Therefore, the range of porosity is not particularly limited, but can be 50% to 90%. The preferred lower limit is 60%, the preferred upper limit is 88%, and the upper limit can be 80% or less. When multiple components are used, it is preferable that the porosity of each component is approximately the same in terms of improving mixability. Note that the porosity in this specification is a value calculated from the ratio of bulk density to true density.

When a mixture of coarse salt (sodium chloride) and bone ash (containing calcium phosphate), silica sand (containing silicate), or coral sand (containing calcium carbonate) is heated in a microwave oven and the temperature immediately after removal and how quickly it cools are compared, the following trends may be observed depending on the conditions.
(1) In terms of how long it takes for food to cool down when mixed in the same ratio, the order is calcium phosphate >> silica sand > coral sand, and the temperature immediately after removing food from the microwave when mixed in the same ratio generally tends to be coral sand > silica sand > calcium phosphate (Figure 1).
(2) Mixtures of sodium chloride and silica sand tend to have the same difficulty in cooling over a relatively wide range of silica sand mixing ratios, from 10% by weight to 25% by weight.
(3) Mixtures of sodium chloride and coral sand have the property of being particularly slow to cool, especially those with a mixture ratio of 80 parts salt and 20 parts coral or 75 parts salt and 25 parts coral (Figure 2).
(4) A mixture of sodium chloride and calcium phosphate tends to become more difficult to cool as the proportion of calcium phosphate increases.

The souvenir composition according to the present invention is not limited to waste-derived, natural-derived or animal-derived materials as described above, and may contain 70-85% by weight of sodium chloride and 15-30% by weight of one or more components selected from calcium carbonate, calcium phosphate and silicate, based on the total weight of the composition. In the case of a three-component or four-component composition, the preferred compositions are 70-85% by weight of sodium chloride, 10-18% by weight of porous calcium carbonate, and 5-12% by weight of calcium phosphate and/or silicate, based on the total weight of the composition. Increasing the proportion of silicate here tends to increase the temperature immediately after heating, while increasing the proportion of calcium phosphate tends to make it difficult to cool, so it is preferable to adjust this by using an outer covering.

In one embodiment, the commemorative item of the present invention is the above-mentioned composition for commemorative items wrapped in a water-permeable material. The water-permeable material is sufficient if it can withstand heating and keeping warm conditions using a microwave oven or a heater, has a heat resistance temperature of 100°C or higher, preferably 120°C or higher, and more preferably 150°C or higher, as measured in accordance with JIS S 2029, and can supply moisture (water) of 0.8% to 5% by weight of the total weight of the composition for commemorative items to the surface of the composition for commemorative items, which is the content, by spraying for an allowable time. Representative inexpensive materials include polyester nonwoven fabric and polypropylene nonwoven fabric. In this embodiment, Soft Bag LL with Fancy Wrapping Flowers (manufactured by Cando Co., Ltd., material: polypropylene nonwoven fabric, JAN code: 4542804042672) is used as the water-permeable material. Such a commemorative item can be produced by sandwiching the above-mentioned commemorative composition between two large pieces of nonwoven fabric, heat-sealing the four sides of the composition with a sealer, and then cutting off the excess fused portions, as shown in Figure 3.

It is useful to store the memento wrapped in the water-permeable material in a sealable, water-impermeable bag. A plastic zipper bag can be used as a sealable, water-impermeable bag because it is flexible and can be integrated with an outer bag. A typical example is Ziploc (registered trademark). However, heat resistance is required for long-term storage such as 3 to 4 months in a heating device or repeated heating in a microwave oven, etc. Therefore, when repeatedly heating in a microwave oven, etc., it is recommended to remove the memento wrapped in the water-permeable material, heat it, and then return it to the bag for use, or to use other heat-resistant, water-impermeable bags such as those made of polypropylene or silicone rubber.

The souvenir 10 shown in FIG. 4 is made by wrapping the souvenir composition described above in a water-permeable material 2 and storing it in a water-impermeable bag 4 that can be sealed with a sealing portion (zipper) 3, and the water-impermeable bag 4 is contained in an outer bag 6. The outer bag 6 is not limited to what is generally called a bag, and can be anything that wraps the outside, including stuffed toys, belly warmers, charms, pillowcases, etc. There are no particular restrictions on the material of the outer bag, but when a plastic zipper bag is used as the water-impermeable bag, a laminated cloth that can be fused to the zipper bag is preferably used. In this case, it is preferable that the outside of the laminated cloth is treated with a water-repellent finish to prevent dirt. In addition, when importance is placed on softness to the touch, silk, gauze, double gauze, etc. can also be used.

The outer bag 6 and the sealable water-impermeable bag 4 may or may not be integrated, but if they are integrated, they can be produced by covering both sides with laminated fabric with the sealing portion (zipper) closed, and heat fusing the laminated fabric together with the sealing portion, leaving a fusing allowance 7 of about 5 to 10 mm at the end of the sealing portion, for the three sides excluding the opening edge 5 of the sealing portion, as shown in Figure 5a.

As shown in Fig. 5b and Fig. 5c, a heat-retaining material 8 may be provided between the outer bag 6 and the sealable water-impermeable bag 4. Examples of the heat-retaining material 8 include felt, double gauze, and plastic cushion sheets for food shelves.

When sandwiching the heat retaining material 8 between the outer bag 6 and the sealable water impermeable bag 4, it is preferable to heat seal the heat retaining material 8 together, since this will prevent the heat retaining material 8 from shifting out of position. As a result of heat sealing, the state shown in Figure 5d is obtained. In this embodiment, a tabletop sealer (T-130 model, manufactured by Fuji Impulse Sealer Co., Ltd.) is used as the sealer for heat sealing.

The method of using the commemorative item of the present invention includes spraying water on the surface of the commemorative item wrapped in the water-permeable material to the extent that the center does not become wet, and heating or keeping warm in a microwave oven or a heater. The amount of water sprayed here is preferably 0.5 to 5% by weight of the total weight of the composition for the commemorative item. A more preferred upper limit is 3% by weight, and an even more preferred upper limit is 2.5% by weight. When the total weight of the composition is just under 100 g, the microwave oven is typically heated for 1 minute 30 seconds to 2 minutes at 500 W, or 40 seconds to 1 minute 30 seconds at 900 W. As the heater, a hand towel heater, commonly known as a hot cabinet or towel warmer, is preferably used.

As shown in Figs. 13 and 14, the multi-layered warming pocket warmer 11 of the present invention is a cloth storage bag 12 having three pockets formed by two partition cloths 14a and 14b inside, in which a souvenir 20 is stored in the first pocket 13 and the third pocket 15, and a coral 22 surrounded by a heat-resistant material 18 is stored in the second pocket 17. The heat-resistant material shown in Fig. 15 refers to a packaging material for the coral used to prevent the coral from burning the surroundings when heated in a microwave oven and becoming too hot. In this embodiment, a spatter sheet made of carbonized fiber is used for protection. Other heat-resistant materials include, for example, urethane rubber, glass fiber sheet, silicone rubber, a composite material of silicone rubber and linen cloth, a composite material of silicone rubber and aramid fiber sheet, and polyester sheet. The partition cloth is not essential as long as it can stabilize the state in which the heat-resistant material surrounding the coral is sandwiched between the souvenirs.

In one embodiment, the commemorative item of the present invention is obtained by adding water and starch paste to the above-mentioned composition for commemorative items, mixing and shaping the composition. The amount of starch paste added is 0.75 to 1.25, assuming the total weight of the components other than sodium chloride in the composition for commemorative items to be 1. The amount of water added is 3% to 12%, assuming the total weight of the sodium chloride in the composition for commemorative items to be 1. If the composition for commemorative items contains a silicate-containing component, particularly silica sand, the resulting shaped object will be denser and more firmly packed.

In one embodiment, the souvenir of the present invention is a souvenir in which the above-mentioned souvenir composition is stored in a bag.

Example 1 (Table Salt)
220g of edible salt was spread to the top of a Tupperware (12cm long x 8cm wide x 3cm high) until the height inside the Tupperware was about 3cm (bulk density 0.76g/ ^cm3 , true density: 2.16g/ ^cm3 , porosity: 64.8%), and the surface was sprayed with water 50 times with a spray bottle (spray amount 10cc, 4.5% by weight of edible salt), and then heated in a 900W microwave oven for 2 minutes. After that, with the lid of the Tupperware open, the temperature was measured over time using a commercially available digital thermometer (DRETEC O-274IV cooking thermometer), with the center temperature at a depth of about 2cm from the surface and the surface temperature at a depth of about 1cm from the surface. The results are shown in Table 1.

Example 2 (Coral Sand 1)
Instead of salt, 220 g of coral sand, whose main component is calcium carbonate, was spread out in the Tupperware to a height of about 2.6 cm (bulk density 0.88 g/cm ³ , true density: 2.7-2.9 g/cm ³ , porosity: 67.4%-70.0%), and water was sprayed 50 times (spray volume of 10 cc, 4.5% by weight of the coral sand), and the temperature change over time was measured in the same manner as in Example 1. The results are shown in Table 1.

Example 3 (Coral Sand 2)
Instead of salt, 220 g of coral sand was spread to a height of about 2.6 cm inside the Tupperware, and water was sprayed over 200 times to moisten the entire surface. The temperature change over time was measured in the same manner as in Example 1. The results are shown in Table 1.

Example 4 (Silica Sand)
Instead of salt, 220 g of beach sand collected from Yoron Island was spread in the Tupperware to a height of about 2.8 cm (bulk density: 0.82 g/ ^cm3 , true density: 2.5 g/ ^cm3 , porosity: 67.2%), and water was sprayed on it. Except for this, the temperature change over time was measured in the same manner as in Example 1. The results are shown in Table 1.

As can be seen from Table 1, the salt in Example 1 had little difference in temperature between the center and the surface. In addition, the center temperature of Coral 1 in Example 2 dropped by 36 degrees in the first 5 minutes of measurement, but the rate of temperature drop thereafter was the slowest among the three types. The center temperature of the sand in Example 4 dropped by 39 degrees in the first 5 minutes of measurement, just like Coral 1, and was the lowest among the three types. In addition, in comparing Examples 2 and 3, it was expected that the temperature would rise if Coral Sand 2, which still retains moisture, was placed in a microwave oven, but it did not rise as much as expected, and the inside of Coral 1, which should have been almost dry, had a higher temperature. In addition, in comparing Example 2 (Coral 1) and Example 4 (Quartz Sand), the porosity in the dry state was almost the same, but there was a large difference in heat retention, suggesting that the material and the water retention resulting from it have a greater influence than the porosity.

Visual observation of the properties revealed that salt has the highest temperature when heated while retaining moisture, but if it is kept too hot it will harden, so it was found that if it contains too much water it is not suitable for use as a pocket warmer.

Example 5
Using coral sand 3 with a "beach-like" texture, which was obtained by pouring water directly over the coral sand and then draining it off, rather than using a spray bottle, and which has a higher moisture content than coral sand 2 in Example 3, we varied the heating time in a 900W microwave oven and measured the temperature immediately after removing it from the oven. The results are shown in Table 2.

According to Table 2, it was found that the temperature of the deep part of the coral sand 3 was higher than that of the surface, regardless of the heating time, and heat was transferred from the deep part to the surface. In addition, the temperature of the deep part of the coral sand 3 peaked out near the boiling point of water after 1 minute 30 seconds, and it was found that the added energy was used as latent heat when the water that fell to the deep part by gravity evaporated.
From the results of Examples 2 and 3 and Table 2, it was found that if coral sand is too moist, the temperature does not rise easily, and if the moisture is removed, the temperature does not rise any more, so it is important to spray water on the surface of the warming hand warmer just enough to prevent the center from getting wet. This result is advantageous because it is easier to spray less frequently.
Considering the results of Example 5, in Example 2, the reason why the surface reached near the boiling point of water immediately after removing the microwave, while the deeper part rose above the boiling point of water, is thought to be that when there was almost no water in the deeper part, the specific heat of calcium carbonate and air (limestone has a value of 920 J/Kg/°C, and air is about 1000 J/Kg/°C) was about one-quarter of the specific heat of water (4189 J/Kg/°C), resulting in a rapid temperature rise.

Taking all of the above into consideration, it was speculated that because the salt inside the coral with a moist surface and the internal temperature of the coral 1 with a moist surface were high, a mixture of salt and coral sand that retained a slight amount of moisture would be suitable for a pocket warmer.

Example 6-1 (Calcium phosphate)
As a calcium phosphate-containing component, 110 g of commercially available natural bone ash (manufacturer: Takesho Seiko Co., Ltd., product code: TO804013) was placed in a Tupperware (length 12 cm x width 8 cm x height 3 cm) to a height of about 2.5 cm (bulk density 0.46 g/cm ³ , true density: 3.14 g/cm ³ , porosity: 85.4%), and the surface was sprayed with water 50 times (Example 6-1) or 230 times (Example 6-2) using a spray bottle, and then heated in a 900 W microwave oven for 2 minutes. Thereafter, with the lid of the Tupperware open, a commercially available digital thermometer (DRETEC O-274IV cooking thermometer) was inserted near the center and the surface to measure the change in temperature T over time, and the properties were visually observed. The results are shown in Table 3. The temperature change over time was provisionally curve-fitted by the least squares method using the following model formula with variables _T0 and B. (Unless otherwise specified, _T0 is the deep layer temperature immediately after removing the oven from the range, _T∞ is the indoor temperature controlled to a constant value, B is the coefficient of the following formula, and ^σ2 is the error variance.) B was used as an index of the difficulty of cooling.
T = T _∞ + (T ₀ - T _∞ ) exp (-Bt)
Example 6-2
The surface was sprayed with water 230 times with a spray bottle to wet the deep layers, and the same procedure as in Example 6-1 was followed to measure the temperature change over time and to visually observe the properties. The results are shown in Table 3.
Example 6-3
The same procedure as in Example 6-1 was followed except that the surface was not sprayed with mist, and the temperature change over time was measured and the properties were visually observed. The results are shown in Table 3.

According to Table 3, it was found that in Example 6-2, the deep layer temperature was highest in the first 20 minutes, while in Example 6-3, the deep layer temperature was highest after the last 20 minutes. It was also found that in Example 6-1, the surface temperature dropped quickly, while in Example 6-2, the surface temperature was highest in the first 20 minutes. Overall, it was found that the temperature immediately after heating was high in Example 6-2, which retained moisture, while the temperature of Example 6-3, which is in powder form, tends to be slightly slower to cool.

Generally, the air layer (thermal conductivity 0.025-0.030 W/m/K) has the greatest heat retention effect, and thermos flasks create a vacuum by eliminating this air layer, creating an insulating effect and retaining heat. In light of this, it is expected that something that is dry and has a high porosity will have air between the particles, creating air layers, resulting in high heat retention, meaning that while the temperature at the center is high, the air layer keeps the heat in and makes it difficult for heat to be transferred to the outside, so the temperature does not feel hot to the body, and this characteristic was clearly evident in Example 6-3.

On the other hand, the reason why the deep layer temperature in the first 20 minutes of Example 6-2 is highest when it contains a lot of moisture is thought to be because, unlike Example 6-3, the inherent water retention of the material and the property of water to store heat are utilized to retain heat. Looking at the results of Example 6-1 in Table 3, despite the fact that the porosity is higher than that of coral or sand, there was significant heat dissipation in the deep layers, and it was speculated that factors such as the material and water retention have a greater impact than the porosity when spraying water for heating.

It was also found that calcium phosphate hardens when it absorbs moisture, so this point must be taken into consideration when mixing.

Example 7 (measurement with different mixing ratios of salt and calcium phosphate)
A total of 100 g of coarse salt (origin: Setouchi coarse salt, manufacturer: Salt Company, Inc.) and calcium phosphate were placed in a nonwoven fabric measuring approximately 17 cm in length and 11.5 cm in width, folded in half lengthwise (approximately 8.5 cm in length and 11.5 cm in width), and heated in a 900 W microwave oven for 1 minute. As shown in Figure 6, the fabric was removed and placed on a newspaper, the folded part was returned to its original position, and a thermometer was inserted. The measurement results of the temperature change over time are shown in Table 4.

As can be seen from Table 4, when the calcium phosphate ratio was 85%, the temperature and heat retention immediately after removal from the microwave were the highest. This suggests that when making a composition of multiple components, it may be necessary to consider the possibility of an appropriate blending ratio. In addition, since moisture seeped out of the nonwoven fabric immediately after heating, it was suggested that when using it as a warming hand warmer, it would be appropriate to place the nonwoven fabric bag containing the composition in another water-repellent, heat-resistant bag.

Example 8 (measurement with different salt and coral blend ratios)
A total of 100 g of salt and coral was placed in a nonwoven fabric measuring approximately 17 cm in length and 11.5 cm in width, sprayed with water 50 times, folded in half lengthwise (approximately 8.5 cm in length and 11.5 cm in width), and heated in a 500 W microwave oven for 1 minute and 30 seconds. As shown in Figure 6, the fabric was removed and placed on a newspaper, the folded part was returned to its original position, and a thermometer was inserted. The measurement results of the change in temperature over time are shown in Table 5. The surrounding environment was a room temperature of 25 degrees and a humidity of 51%.

From Table 5, it was found that as the proportion of coral increases, it becomes harder to cool, while the temperature immediately after removing it from the microwave becomes lower. As an overall trend, in the first 30 minutes, the 10% coral component had better heat retention than the 30% coral component. Taking Examples 7 and 8 together, it was suggested that when making a composition of multiple components whose surface does not harden, there may be an appropriate blend ratio within the range containing 5 to 20 weight percent waste-derived, natural-derived, or animal-derived materials, regardless of the material or porosity.

Example 9 (Beaker/Coral)
100g of pure coral sand or a composition obtained by thoroughly mixing coarse salt and coral sand in a specified ratio was placed in a 150cc beaker to a total of 100g, and heated for 1 minute in a 900W microwave oven with two paper plates laid on top. After heating, a cooking thermometer (DAISO C008, made of glass, indicator: kerosene) was inserted upright in the center as shown in Figure 7, and the beaker was tilted so that it fit into the spout of the beaker. The gap in the content that was created when the thermometer was tilted was filled by covering it. This operation ensured that the position of the thermometer did not change, the position of the thermometer could be set almost the same, moisture did not bleed into the nonwoven fabric, and it was possible to observe without moving it even a millimeter. The measurement results of the temperature change over time are shown in Table 6. The surrounding environment was set to 22 degrees Celsius and 35% humidity on the air conditioner.

From Table 6, it can be seen that a mixture ratio of 80% salt and 20% coral or 75% salt and 25% coral has the property of being particularly resistant to cooling. This tendency was also seen in Example 8, which used nonwoven fabric, suggesting that this property is derived from the mixed composition, regardless of whether the outer container is made of nonwoven fabric or a beaker.

Example 10 (Beaker/Calcium Phosphate)
The temperature change over time was observed in the same manner as in Example 9, except that calcium phosphate powder was used instead of coral sand. The results are shown in Table 7. The surrounding environment was an air conditioner with a set temperature of 22 degrees and a humidity of 35%.

From Table 7, it can be seen that as the proportion of calcium phosphate increases, the food tends to become slower to cool.

Example 11 (Beaker/Silica Sand)
The temperature change over time was observed in the same manner as in Example 9, except that silica sand was used instead of calcium phosphate powder. The results are shown in Table 8. The surrounding environment was an air conditioner with an air conditioner set at 22 degrees and a humidity of 35%.

From Table 8, we can see that the mixture of salt and silica sand has the same cooling effect over a relatively wide range of silica sand mixing ratios, from 10% to 25% by weight, but that the higher the silica sand ratio, the lower the temperature immediately after removing the pan from the range. However, when only silica sand (11) was used, the temperature dropped dramatically immediately after removing the pan from the range. This is thought to be due to the lack of moisture in the silica sand itself.

Comparing the results of Examples 9 to 11, which were carried out under the moisture conditions of coarse salt, it was found that, in terms of how long it takes for food to cool down when mixed in the same ratio, calcium phosphate >> silica sand > coral sand tends to be the order of calcium phosphate >> silica sand > calcium phosphate, and that, when mixed in the same ratio, the temperature immediately after removing the food from the microwave tends to be coral sand > silica sand > calcium phosphate.

Example 12 (Beaker/3, 4 components)
Based on the results of the studies of Examples 9 to 11 above, heat dissipation tests were carried out under the same conditions as in Example 9 using the ternary and quaternary compositions shown in Table 9. The results are shown in Table 9. The surrounding environment was an air conditioner with a set temperature of 22°C and a humidity of 35%.

From Table 9, it is difficult to say which of (23) and (24) is better in terms of how long it takes to cool down, but the temperature after one hour differed depending on the temperature immediately after removal. Comparing (23) and (25), it was found that by replacing all calcium phosphate with silica sand, the temperature immediately after removal from the microwave rose dramatically.

Example 13 (Cushion-surrounded beaker/3, 4 components)
As shown in Figures 8 and 9, a heat dissipation test was carried out under the same conditions as in Example 12, except that a polyethylene food shelf cushion sheet was wrapped around the food shelf four times. The results are shown in Table 10. The surrounding environment was an air conditioner with a set temperature of 22 degrees and a humidity of 35%.

From Table 10, it can be seen that the ^σ2 values are all smaller than those in Table 9 for Example 12 before the cushion was placed around the samples, and that blocking heat radiation from the beaker glass brought the experiment closer to an ideal environment. The three-component and four-component compositions (27), (28), (29), and (31) all had low temperatures immediately after removal from the microwave, but tended to cool slowly, while the composition (30) of coarse salt, coral, and silica sand had a high temperature immediately after removal from the microwave, but cooled slightly more easily, a tendency similar to that of Example 12. Also, a comparison with the B values in Table 9 shows that the compositions generally tended to cool more slowly.

Example 14 (Investigation of the amount of water required until the performance of coarse salt is lost)
Two patterns were used, a normal beaker 1 containing a total of 100 g of coarse salt in a 150 cc beaker, and a beaker 2 wrapped around the beaker with a polyethylene food shelf cushion sheet, and heated for 1 minute in a 900 W microwave oven with two paper plates laid on top. After heating, as shown in FIG. 7, a cooking thermometer (DAISO C008, made of glass, indicator: kerosene) was inserted upright in the center and the beaker was turned over so that it fit into the spout of the beaker. The gap in the content that was created when the thermometer was turned over was filled with a cover, and the temperature change over time was measured. Here, the "wet" sample was coarse salt that had not been treated in any way, and the "dry" sample was one that had been heated in a microwave oven at 900 W for 1 minute four times, after which 1% of the moisture had been removed and the weight was 99 g. The results are shown in Table 11. The surrounding environment was an air conditioner with a set temperature of 22 degrees and a humidity of 35%.

Comparing the B values of beaker 2 in (34) and (35) in Table 11, it appears that even if 1% of the water is lost from the coarse salt, there is no significant change in the resistance to cooling, but the temperature immediately after removing it from the microwave drops significantly, and it is no longer possible to obtain satisfactory characteristics as a pocket warmer. Conversely, it is suggested that as long as the salt component always retains 1% moisture, it will be able to maintain sufficient characteristics.

Example 15 (Investigation of the amount of water required to restore the performance of coarse salt)
99g of dry coarse salt was placed in 150cc beakers 1 and 2, and the temperature immediately after removing the salt from the microwave was compared between spraying 5 times (equivalent to 1cc) and spraying 10 times (equivalent to 2cc). The results are shown in Table 12. The surrounding environment was an air conditioner with a set temperature of 22 degrees and a humidity of 35%.

From Table 12, it was found that the properties of the coarse salt can be restored by spraying it five times, but even if this was done ten times, there was almost no change in the temperature immediately after removing it from the microwave. This suggests that if the pocket warmer is placed in a non-permeable bag in advance and an excess amount of spray is used, it is possible to repeatedly heat the salt in the microwave several times.

Example 16 (Cushion-surrounded beaker/3, 4 components)
A heat dissipation test was carried out under the same conditions as in Example 13. The results are shown in Table 13. The surrounding environment was an air conditioner with a set temperature of 22 degrees and a humidity of 35%.

From Table 13, the temperature immediately after use is lower for (41) than for (40), but there is no significant difference after 5 minutes, so (41) is considered to be safer to use.

Example 17 (Comparison of temperature changes between surface temperature and deep temperature of nonwoven fabric)
A nonwoven bag was filled with salt, coral sand, calcium phosphate, and silica sand to a total of 100g, and heated for 1 minute in a 900W microwave oven with two paper plates laid on top. After heating, the bag was immediately removed and a cooking thermometer (DAISO C008, made of glass, indicator: kerosene) was inserted into the center of the nonwoven as shown in Figure 10, and another thermometer was placed on the surface of the nonwoven and fixed with packing tape. The nonwoven was placed over the thermometer on the surface, and a heat dissipation test was performed. The results are shown in Table 14. The surrounding environment was an air conditioner set at 22 degrees and humidity at 35%.

From Table 14, it was found that after 5 minutes, the heat was gradually transferred from the inside to the nonwoven fabric, and the surface temperature became higher. The surface temperature immediately after was 44°C to 58°C, but it is believed to be higher. According to various literature, low-temperature burns are said to occur when touching a 44°C object for 3 to 4 hours, a 46°C object for 30 minutes to 1 hour, or a 50°C object for 2 to 3 minutes. From this perspective, it was found that it is not recommended to touch directly any of the products containing silica sand (46), (47), (49), and (50) in the early stages of heat dissipation, and that temperature adjustment with a cloth cover or the like is necessary, but it was found that there is little risk of low-temperature burns with products not containing silica sand.

Example 18 (Comparison of deep temperature and sensible temperature)
A nonwoven bag was filled with salt, coral sand, calcium phosphate, and silica sand to a total of 100 g, and heated for 1 minute in a 900 W microwave oven with two paper plates laid on top of each other. After heating, the bag was immediately taken out and held in the hand, a cooking thermometer (DAISO C008, made of glass, indicator: kerosene) was inserted into the center of the bag as shown in Figure 11, the mouth of the bag and the thermometer were held in the hand together to close the bag, the part containing the mixture was touched, and the temperature and physical sensation were recorded. When touching the mixture, the hand that was least warm was used. The results are shown in Table 15. The surrounding environment was an air conditioner set at 22 degrees and humidity at 35%.

From Table 15, when compared to the temperatures obtained in the deep temperature and surface temperature experiment in Example 17, it was found that the deep temperature that felt lukewarm to the touch on the surface lasted for about 20 to 30 minutes.

Example 19 (Production of a sculpture containing salt and granite powder - Okijio)
Salt (product name: "Nihonkaisui Table Salt" (Setouchi), manufactured by Nihonkaisui Co., Ltd., Ako Factory), granite powder (from Okazaki, obtained from a lantern shop in Okazaki), and starch paste (Fueki AB paste, manufactured by Fueki Glue Co., Ltd.) were prepared. The salt was powdered in advance using a mill, and then mixed well in a ratio of 10 parts salt, 2 parts granite powder, 2 parts starch paste, and 0.4 parts water to create a sculpture. For the head, a straw was cut lengthwise to make a semicircular cross section, and pressed to draw eyes. After that, it was left to dry naturally for at least one day, and the cheeks were colored red with poster paint to obtain a sculpture (Jizo) as shown in Figure 12. The heart ornament held by the Jizo was made of paper clay, dried, colored with poster paint, dried again, and attached with starch paste to the Jizo that had been dried for at least one day. It was found that this sculpture, apart from the paper clay, is light and does not use any glue or plaster, and therefore has the characteristic that it easily dissolves when placed in water.

Example 20
After drawing the face, I found that applying a mixture of two parts water and one part starch glue with a brush made the face harder.

Example 21 (Model containing salt and granite powder - effect of adding silica sand)
Salt (product name: "Nihonkaisui Table Salt" (Setouchi), manufactured by Nihonkaisui Co., Ltd., Ako Factory), granite powder (from Okazaki, obtained from a lantern shop in Okazaki), silica sand powder (from Gifu Prefecture, manufactured by Shirai Soap Co., Ltd., sold by Rakuraku Eco Shop Co., Ltd.), and starch glue (Fueki AB glue, manufactured by Fueki Glue Kogyo Co., Ltd.) were prepared, and the salt was first powdered in a mill, then mixed well in a ratio of 10 parts salt: 1 part granite powder: 0.1 parts silica sand powder: 1 part starch glue: 1 part water, and shaped. A shaped object was then obtained through the same process as in Example 19. The resulting shaped object had increased density and was firmly packed.
