Description

[Technical Field]

[0001] The present invention relates to a solid cosmetic product and a method for producing the same. [Background technology]

[0002] BACKGROUND ART Conventionally, solid cosmetics in which cosmetics of multiple colors are arranged are known.

[0003] For example, Patent Document 1 discloses a multicolor oil-based solid cosmetic in which a colored first partial composition that exhibits an application color is sandwiched between a colored second partial composition that exhibits a visible color. The multicolor oil-based solid cosmetic disclosed in Patent Document 1 has a mass ratio of the first partial composition to the second partial composition of 9:1 to 7:3, and the difference in hiding power between the application of the first partial composition and the application of the second partial composition is 15 or more. When applied to the skin, the first partial composition hides the second partial composition, and substantially only the first partial composition exhibits color.

[0004] Patent Document 2 discloses a solid cosmetic product and a method for producing the same, in which two or more compositions are fluidized by heating and ejected in the form of droplets from orifices onto a support to form a deposit. By depositing two or more compositions, it is possible to mold solid cosmetics in which the deposited masses differ in color, for example, without the need for a molding mold.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-6349 [Patent Document 2] Patent No. 6705603 Summary of the Invention [Problem to be solved by the invention]

[0006] In the configuration disclosed in Patent Document 1, the second partial composition is sandwiched between the first partial compositions, so no matter which direction the multicolor oil-based solid cosmetic is applied to the skin from, at least the first partial composition is applied last. However, with regard to the multicolor oil-based solid cosmetic described in Patent Document 1, no consideration has been given to applying the first partial composition and the second partial composition in a mixed state.

[0007] Furthermore, in the manufacturing method described in Patent Document 2, when a fluidized composition is ejected from an orifice, the larger the droplet size, the more easily the droplets deposited on the support deform, making it difficult to form large solidified agglomerates into the desired shape. Furthermore, when the droplet size is reduced, a large number of droplets must be collected to form agglomerates, and it is also difficult to form the agglomerates into the desired shape.

[0008] In view of the above, one aspect of the present invention aims to provide a solid cosmetic preparation that can be applied in a mixed state of a plurality of different compositions, in which at least one of the compositions substantially maintains the outer shape of the raw material pellets. [Means for solving the problem]

[0009] A solid cosmetic according to one embodiment of the present invention comprises a granular first composition having a first composition and a second composition having a second composition different from the first composition, wherein the granular first composition substantially maintains the external shape of the raw material pellets. [Effects of the Invention]

[0010] According to one aspect of the present invention, a solid cosmetic product can be obtained that can be applied in a mixed state of multiple different compositions, in which at least one composition substantially maintains the outer shape of the raw material pellets.

[Figure 4] FIG. 10 is a partially enlarged schematic view showing a second modified example of a solid cosmetic according to one embodiment of the present invention. [Figure 5] 1A to 1C are diagrams illustrating a method for producing a solid cosmetic product according to one embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0012] One embodiment of the present invention will be described in detail below. The embodiment described below is an example in which a solid cosmetic material 2 of the present invention is applied to a stick-shaped (rod-like) lipstick. Figure 1 is a perspective view showing a lipstick with a container 1 that uses a solid cosmetic material 2 according to one embodiment of the present invention.

[0013] In this embodiment, "raw material pellets" refers to granular materials that have been molded into a predetermined shape outside the container (mold 4) for molding the solid cosmetic product 2. This also includes pellets that are commercially available as molding raw materials. "The outer shape of the raw material pellets is substantially maintained" refers not only to cases where the outer shape of the raw material pellets is maintained as is (solid), but also to cases where a portion of the outer shape of the raw material pellets is slightly deformed, or where the raw material pellets have completely melted and then solidified while substantially maintaining their shape. In other words, it also includes cases where the shape of the raw material pellets before molding can be inferred from the average shape after molding.

[0014] As shown in FIG. 1 , the solid cosmetic 2 is composed of, for example, a granular first composition 21 having a first composition and a second composition 22 having a different composition from the first composition, and has a mosaic (dot) pattern. The solid cosmetic 2 is contained in a cylindrical dispensing container 3, and the solid cosmetic 2 and the dispensing container 3 together constitute a lipstick with a container 1. FIG. 1 illustrates a solid cosmetic 2 in which the first composition 21 and the second composition 22 are both spherical raw material pellets, and the first composition substantially maintains the external shape of the spherical raw material pellets, while the second composition 22 does not substantially maintain the external shape of the spherical raw material pellets. As described above, it is sufficient that at least one of the multiple compositions is granular and maintains the external shape of the raw material pellets, and the second composition 22 may be a continuous phase, as described below. Furthermore, although the present embodiment illustrates an example in which two compositions are used, the number of compositions may be three or more.

[0015] The first composition 21 and the second composition 22 have different compositions, and at least one of the components they contain is different. For example, if the first composition 21 and the second composition 22 have different colors, the different colors are dispersed throughout the solid cosmetic 2, from the surface to the interior, so that no matter which direction the solid cosmetic 2 is applied to the skin from, the different colors can be applied in a mixed state. This also contributes to the aesthetic appearance of the solid cosmetic 2. The color of each composition may be white or colorless and transparent.

[0016] The first composition 21 and the second composition 22 contain, for example, wax, other oils, antioxidants, and coloring materials. Various compositions can be used, not limited to the compositions of the embodiments described below. Various ingredients, such as oils, powders, surfactants, UV absorbers, film-forming agents, anti-fading agents, antioxidants, antifoaming agents, cosmetic ingredients, preservatives, and fragrances, can be appropriately blended to impart various effects, as long as the effects of the present invention are not impaired.

[0017] Oils include hydrocarbons, fats and oils, waxes, hardened oils, ester oils, fatty acids, higher alcohols, silicone oils, fluorine-based oils, oily gelling agents, etc., regardless of their origin (vegetable oil, synthetic oil, etc.) and whether they are solid oil or liquid oil.

[0018] Specific examples of waxes include polyethylene, microcrystalline wax, beeswax, paraffin, candelilla wax, carnauba wax, rice bran wax, and sucrose tetrastearate triacetate. The wax content is preferably 5 to 25% by mass relative to the total amount of each composition. This ensures usability as the solid cosmetic preparation 2 while improving the moldability of the raw material pellets during production, as described below.

[0019] In addition to waxes, hydrocarbon oils such as hydrogenated polydecene, hydrogenated polyisobutene, polybutene, polyisobutylene, polyisoprene, liquid paraffin, squalane, hydrogenated polydecene, and petrolatum, diisostearyl malate, pentaerythrityl tetraethylhexanoate, di(phytosteryl / octyldodecyl) lauroyl glutamate, polyglyceryl-2 triisostearate, dipentaerythrityl hexahydroxystearate (trade name: Cosmol 168M), polyglyceryl-2 isostearate / dimer dilinoleate copolymer (trade name: Hi-Lucent ISDA), or dimer dilinoleyl dimer dilinoleate (trade name: LUSPLAN) DD-DA7), dimer dilinoleic acid esters such as dimer dilinoleic acid (phytosteryl / isostearyl / cetyl / stearyl / behenyl), or lauroyl glutamic acid esters such as di(octyldodecyl / phytosteryl / behenyl) lauroyl glutamate and (bis(lauroyl glutamate / lauroyl sarcosine) dimer dilinoleyl), and silicone oils such as simethicone, diphenylsiloxyphenyl trimethicone, diphenyl dimethicone, dimethicone, and fluorine-modified alkyl silicone.

[0020] Examples of coloring materials include red iron oxide, yellow iron oxide, black iron oxide, cobalt oxide, ultramarine, Prussian blue, titanium oxide, zinc oxide, titanium mica, titanium iron oxide-treated titanium mica, glass flakes, fish phosphate foil, bismuth oxychloride, Red No. 228, Red No. 226, Blue No. 404, Yellow No. 5, Red No. 505, Red No. 230, Red No. 223, Orange No. 201, Red No. 213, Yellow No. 204, Yellow No. 203, Blue No. 1, Green No. 201, Purple No. 201, Red No. 202, and Red No. 204. One or more coloring materials can be selected and blended as desired. The coloring materials can also be blended after being treated, for example, to be hydrophobic.

[0021] FIG. 2 is a partially enlarged schematic diagram of a solid cosmetic product 2 according to one embodiment of the present invention, showing an example in which both the first composition 211 and the second composition 221 substantially maintain the outer shapes of the raw material pellets.

[0022] As shown in FIG. 2, the solid cosmetic product 2 has a mosaic (dot) pattern, with granular first composition 211 and granular second composition 221 melted and dispersed throughout. In this form, the difference between the melting temperatures of the waxes contained in the first composition 211 and the second composition 221 is preferably 0 to 10°C. The melting temperature refers to the temperature at which the wax becomes completely liquid. This allows the first composition 211 and the second composition 221 to melt and adhere to each other, improving the adhesion between the two compositions. Note that the schematic diagram in FIG. 2 shows a state in which the spherical external shapes of the raw material pellets of the first composition 211 and the second composition 221 are maintained. However, depending on the heating temperature, for example, the surfaces of the raw material pellets of both compositions may be slightly deformed (moved) by melting, filling in the voids between the compositions, thereby substantially eliminating the voids.

[0023] FIG. 3 is a partially enlarged schematic view showing a first modified example of a solid cosmetic preparation 2 according to one embodiment of the present invention, and FIG. 4 is a partially enlarged schematic view showing a second modified example of a solid cosmetic preparation 2 according to one embodiment of the present invention.

[0024] In the embodiment shown in Figures 3 and 4, the first compositions 212 and 213 are granular, and the second compositions 222 and 223 are a continuous phase. A continuous phase refers to a state in which the boundaries between the granules have disappeared, or a single phase state. In the solid cosmetic 2 of this embodiment, the granular first compositions 212 and 213 are dispersed throughout the continuous phase of the second compositions 222 and 223, forming a dot pattern. Therefore, even in this embodiment, multiple different compositions can be applied in a mixed state. While this embodiment shows an example in which the first compositions 212 and 213 are granular, the shape of the first compositions 212 and 213 can be any shape. This allows the appearance of the solid cosmetic 2 to have a pattern other than a dot pattern.

[0025] 3, the melting temperature of the wax contained in the second composition 222 is lower than the melting temperature of the wax contained in the first composition 212. In this case, the difference in melting temperature between the waxes contained in the first composition 212 and the second composition 222 is not particularly limited, but is preferably 5 to 25°C.

[0026] On the other hand, in the embodiment shown in FIG. 4, the melting temperature of the wax contained in the second composition 223 is higher than the melting temperature of the wax contained in the first composition 213. In this embodiment, the difference between the melting temperatures of the wax contained in the first composition 213 and the wax contained in the second composition 223 is preferably within 10°C. Although the granular shape of the first composition 213 is partially deformed upon melting, the outer shape of the raw material pellets is substantially maintained, and therefore the first composition 213 and the second composition 223 can be applied in a mixed state. Note that if the difference in the melting temperatures of the waxes exceeds 10°C, it becomes difficult for the first composition 213 to maintain the outer shape of the raw material pellets.

[0027] Next, a method for producing the solid cosmetic material 2 will be described.

[0028] FIG. 5 is a diagram illustrating a method for producing a solid cosmetic material 2 according to one embodiment of the present invention.

[0029] First, raw material pellets for a first composition 21 having a first composition and raw material pellets for a second composition 22 having a second composition different from the first composition are prepared. The raw material pellets for the first composition 21 and the raw material pellets for the second composition 22 differ in at least one of the components they contain. For example, if the raw material pellets for the first composition 21 and the raw material pellets for the second composition 22 are different in color, a solid cosmetic preparation 2 can be produced in which different colors are dispersed throughout the solid cosmetic preparation 2, from the surface to the interior. Therefore, regardless of the direction from which the solid cosmetic preparation 2 is applied to the skin, the solid cosmetic preparation 2 can be applied in a mixed state of different colors. Furthermore, an aesthetic appearance can be imparted to the solid cosmetic preparation 2. The color of each composition may be white or colorless and transparent. If the raw material pellets for the first composition 21 and the raw material pellets for the second composition 22 have different components, a solid cosmetic preparation 2 with multiple effects can be produced by preparing pellets of multiple compositions and selecting the raw material pellets appropriately according to the desired effect.

[0030] The raw material pellets can be, for example, spherical. In this case, the particle size of the raw material pellets is preferably greater than 1 mm. The upper limit of the particle size of the raw material pellets can be any size depending on the size of the solid cosmetic product 2. However, if the solid cosmetic product 2 is cylindrical and stick-shaped, it is preferably equal to or less than the radius of the cross section perpendicular to the center line. If the cross section is elliptical, it is preferably equal to or less than the semi-major axis. Specifically, the upper limit of the particle size of the raw material pellets is not particularly limited and can be any size depending on the size of the solid cosmetic product 2. However, it is preferably equal to or less than 10 mm, and more preferably equal to or less than 6 mm. The raw material pellets can be shaped not only as spherical, but also as cylindrical, star-shaped, cubic, etc. Furthermore, the molten composition can be dripped from a syringe and solidified while dripping. Raw material pellets can also be formed into raw material pellets with different compositions (e.g., hues) in the radial direction by molding a certain composition into a sphere and then covering the surface of the spherical composition with a composition of a different composition. Furthermore, cylindrical raw material pellets can be produced in which the outer layer and the inner layer have different compositions (hues).

[0031] In this way, in the step of molding the raw material pellets, it is possible to give the raw material pellets a desired outer shape, or to mold the raw material pellets into a desired different composition.

[0032] In this embodiment, raw material pellets are prepared for both the first composition 21 and the second composition 22, but the second composition 22 may be used in a state other than pellets, such as powder or liquid.

[0033] As shown in FIG. 5( a ), raw material pellets of a first composition 21 and raw material pellets of a second composition 22 are mixed and filled into a molding die 4 .

[0034] 5(b), the mold 4 filled with the raw material pellets of the first composition 21 and the second composition 22 is heated to a predetermined temperature in a heating / cooling device 5, and the raw material pellets of the first composition 21 and the second composition 22 are thermally melted (thermally fused). Here, it is preferable that the first composition 21 and the second composition 22 each contain a wax. The difference between the melting temperature of the wax contained in the first composition 21 and the melting temperature of the wax contained in the second composition 22 can be any value.

[0035] In this case, the heating temperature is preferably equal to or higher than the lower of the melting temperatures of the wax contained in the first composition 21 and the wax contained in the second composition 22. The heating temperature is more preferably equal to or higher than the higher of the melting temperatures of the wax contained in the first composition 21 and the wax contained in the second composition 22. This allows the raw material pellets of the first composition 21 and the raw material pellets of the second composition 22 to be welded together, thereby improving the adhesion between the two compositions.

[0036] Note that, when the melting temperature of the wax contained in the second composition 22 is higher than the melting temperature of the wax contained in the first composition 21, the difference between the melting temperatures of the wax contained in the first composition 21 and the wax contained in the second composition 22 is preferably within 10°C. In this case, too, the heating temperature is preferably equal to or higher than the lower of the melting temperatures of the wax contained in the first composition 21 and the wax contained in the second composition 22. This allows the raw material pellets of the first composition 21 and the raw material pellets of the second composition 22 to be welded together, thereby improving the adhesion between the two compositions.

[0037] When the melting temperature of the wax contained in the first composition 21 and the melting temperature of the wax contained in the second composition 22 are the same, the heating temperature is preferably in the range of the melting temperature of the wax to the melting temperature of the wax + 10°C, and more preferably in the range of the melting temperature of the wax to the melting temperature of the wax + 5°C.

[0038] Finally, as shown in Figure 5(c), the thermally melted first composition 21 and second composition 22 are cooled and solidified to obtain a stick-shaped solid cosmetic product 2. For example, a device equipped with a Peltier element can be used as the heating / cooling device 5. This allows heating and cooling to be carried out continuously after each composition is filled into the mold 4. Note that heating from above H4 among the heating steps H1 to 4 shown in Figure 5(b) and cooling from above C4 among the cooling steps C1 to 4 shown in Figure 5(c) may be omitted. [Example]

[0039] Next, experimental examples and working examples of solid cosmetic preparation 2 will be explained with reference to Tables 1 to 7, but they are not intended to limit solid cosmetic preparation 2 of the present invention or the method for producing solid cosmetic preparation 2.

[0040] (Experimental Example 1: Particle size of raw material pellets) For the first composition 21 and the second composition 22, which have the compositions shown in Table 1, granular raw material pellets having the particle sizes shown in Examples 1 to 4 and Comparative Example 1 in Table 2 were prepared. The raw material pellets were heated and melted, then cooled and solidified, and molded to obtain cylindrical solid cosmetic preparations 2 with a diameter of 12.5 mm. Colorant 1 and colorant 2 in Table 1 are colorants with different colors. The numerical values ​​for each component in Table 1 (total content: 100% by mass) indicate the mass % of the total amount. Note that, when the particle size of the raw material pellets is not spherical, it can be, for example, the average of the maximum and minimum diameters. Next, the moldability and appearance of the solid cosmetic preparations 2 obtained in Examples 1 to 4 and Comparative Example 1 were evaluated. The moldability of solid cosmetic preparation 2 refers to the presence or absence of voids in the molded solid cosmetic preparation 2. The appearance refers to the state of maintenance of the external shape of the raw material pellets in the appearance of solid cosmetic preparation 2.

[0041] Moldability was evaluated by visually checking the presence or absence of voids on the surface of the molded solid cosmetic preparation. The results are shown in Table 2 as "no voids: good" and "voids present: poor." Appearance was evaluated by visually checking the appearance of the molded solid cosmetic preparation 2. The results are shown in Table 2 as "granular appearance remained (external shape of raw material pellets was substantially maintained): good" and "granular appearance was lost due to melting (external shape of raw material pellets was not substantially maintained): poor."

[0042] [Table 1]

[0043] [Table 2]

[0044] As shown in Table 2, the solid cosmetic preparations 2 of Examples 1 to 3 were good in both moldability and appearance. The solid cosmetic preparation 2 of Example 4 had voids, but the granular appearance remained. The solid cosmetic preparation 2 of Comparative Example 1 had good moldability, but the particles had dissolved, damaging the granular appearance. From the above results, it was confirmed that in Experimental Example 1, in order to obtain a solid cosmetic preparation 2 with good moldability and appearance, it may be preferable for the particle size of the raw material pellets to be greater than 1 mm.

[0045] (Experimental Example 2: Wax Content) Table 3 shows the results of an investigation into the effect of the wax content in the raw material pellet composition on the moldability of the raw material pellets and the usability of the solid cosmetic preparation 2. The numerical value for each component in Table 3 (total content 100% by mass) indicates the mass % of the total amount. Raw material pellets for Experiments A to E were prepared as the first composition 21 or the second composition 22, and the moldability of the raw material pellets was evaluated. The moldability of the raw material pellets refers to the degree to which the shape is maintained after the melted components are ejected from a syringe. Each of the prepared raw material pellets was further melted by heating and then cooled and solidified to obtain a cylindrical solid cosmetic preparation 2 consisting solely of the first composition 21 or the second composition 22. The usability of the obtained solid cosmetic preparation 2 was then evaluated. The usability of the solid cosmetic preparation 2 refers to the smoothness of the solid cosmetic preparation 2 when applied.

[0046] The moldability of the raw material pellets was evaluated by visually checking how well they maintained their shape after dissolving each ingredient and ejecting it from a syringe. The more the raw material pellets maintained their three-dimensional shape without flattening after being ejected from the syringe, the better the evaluation. The results are shown in Table 3 as "very good (shape as ejected): A," "good (slightly expanded shape): B," and "slightly poor (expanded shape): C." The usability of Solid Cosmetic Preparation 2 was evaluated by a sensory panel of experts, who evaluated the smoothness of the product when applied to the skin. The results are shown in Table 3 as "very good: A," "good: B," "slightly poor: C," and "poor: D."

[0047] [Table 3]

[0048] As shown in Table 3, the moldability of the raw material pellets in Experiments A to D was within a range that allowed them to be molded without any problems, and the raw material pellets in Experiment A were also not defective and within a range that allowed them to be molded without any problems. The usability of solid cosmetic preparation 2 in Experiments A to D was within a range that allowed them to be used without any problems, and the solid cosmetic preparation 2 in Experiment D was also not defective and within a range that allowed them to be used without any problems. In Experiment E, the moldability of the raw material pellets was good, but they were too hard and their usability was poor. From the above results, it was confirmed that there were no problems with the usability of solid cosmetic preparation 2, and that in order to improve the moldability of the raw material pellets, the wax content is preferably 5 to 25% by mass, and more preferably 10 to 23% by mass, of the total amount of the composition.

[0049] (Experimental Example 3: Melting temperature of wax) Using three types of waxes a, b, and c with different melting temperatures shown in Table 4, raw material pellets for compositions A1, A2, B1, B2, C1, and C2 with the compositions shown in Table 5 were prepared. The "melting temperature" in Table 4 refers to the temperature at which the wax becomes completely liquid. Furthermore, colorant 1 and colorant 2 in Table 5 are colorants with different colors. Then, as shown in Examples 5 to 10 and Comparative Examples 2 to 4 in Table 6, two types of raw material pellets were mixed, heated and melted at different heating temperatures shown in Table 6, and then cooled, solidified, and molded to obtain solid cosmetic preparation 2.

[0050] In Examples 5 to 10 and Comparative Examples 2 to 4, the moldability and appearance of the obtained solid cosmetic preparations 2 were evaluated, and an overall evaluation was made by combining these results. The evaluation and evaluation methods for the moldability of solid cosmetic preparations 2 were the same as those in the above-mentioned Experimental Example 1. The results are shown in Table 6.

[0051] The appearance was evaluated in the same manner as in Experimental Example 1, and the results are shown in Table 6 as "The granular appearance remained (the external shape was substantially maintained): Good," "The granular appearance was partially damaged (the external shape was substantially maintained, but part of the external shape was slightly deformed): Fairly good," and "The granular appearance was damaged due to melting (the external shape was not substantially maintained): Poor." The overall evaluation is shown in Table 6 as "Good" if the evaluation results for the moldability and appearance of Solid Cosmetic Preparation 2 did not include "Poor," and as "Poor" if the evaluation results included "Poor."

[0052] [Table 4]

[0053] [Table 5]

[0054] [Table 6]

[0055] As shown in Table 6, solid cosmetic preparation 2 using wax a with a melting temperature of 85°C received a good overall rating when the heating temperature was 85°C (Example 5) or 95°C (Example 6); solid cosmetic preparation 2 using wax b with a melting temperature of 78°C received a good overall rating when the heating temperature was 80°C (Example 7) or 90°C (Example 8); and solid cosmetic preparation 2 using wax c with a melting temperature of 94°C received a good overall rating when the heating temperature was 95°C (Example 9) or 100°C (Example 10). As shown in Comparative Examples 2 to 4, when the heating temperature was too high relative to the melting temperature of each wax, the appearance was impaired. Favorable results were obtained for the moldability and appearance of solid cosmetic preparation 2 when the heating temperature was within the range of the wax melting temperature to the wax melting temperature + 10°C.

[0056] (Experimental Example 4: Wax Combination) The raw material pellets prepared in Experimental Example 3 were mixed in the combinations shown in Table 7, and then heated and melted at the heating temperatures shown in Table 7, followed by cooling, solidification, and molding to obtain Solid Cosmetic Preparation 2. In Table 7, the "difference in wax melting temperature" refers to the difference in melting temperature of the wax contained in the first composition and the second composition. Solid cosmetic preparations 2 of Examples 11 and 12 and Comparative Example 5 were evaluated for moldability and appearance, and an overall evaluation was conducted by combining these results. The evaluation and judging methods for the moldability and appearance of the solid cosmetic preparations and the overall evaluation were the same as those of Experimental Example 3 described above.

[0057] [Table 7]

[0058] As shown in Table 7, both the moldability and appearance of the solid cosmetic preparations 2 of Examples 11 and 12 were good. In the solid cosmetic preparation of Comparative Example 5, the difference in melting temperature between the wax contained in composition C1 and the wax contained in composition B1 was greater than in Examples 11 and 12, and although moldability was good, the granular appearance was impaired.

[0059] From the above results, it can be said that in order to obtain a solid cosmetic preparation 2 that has good moldability and appearance, it is preferable that the difference in melting temperature between the waxes contained in the different compositions is 0 to 10°C.

[0060] In this embodiment, the solid cosmetic 2 is shown as being applied to lipstick, but examples of the solid cosmetic 2 are not limited to lipstick, and include lip cream, balm, foundation, concealer, eye shadow, blush, serum, solid perfume, etc. Also, in this embodiment, the solid cosmetic 2 is shown as being in a stick (rod) shape, but it is not limited to a stick shape and can be in any shape, such as a dish shape for blusher, eye shadow, foundation, etc.

[0061] Although the embodiments have been described above, they are presented as examples and the present invention is not limited to the above embodiments. The above embodiments can be implemented in various other forms, and various combinations, omissions, substitutions, modifications, etc. can be made without departing from the spirit of the invention.
