Summary of the Invention

Problems to be Solved by the Invention

[0005] For example, when manufacturing a personal care product decorated with a plurality of types of compositions such as different colors, a method of manufacturing a personal care product by imparting a shape by molding using a press head having a mold or by pouring a cosmetic into the inside of a rubber mold is known. When a decoration is applied to a planar surface of a base material composed of a composition with another composition, the decorated portion is likely to fall off.

[0006] In view of the above circumstances, an object of the present invention is to provide a personal care product in which a decorated portion is prevented from falling off from a base material and the design quality is improved in a personal care product having a decoration on the surface. [Means for solving the problem]

The personal care product preferably has a base material having grooves that are recessed in the thickness direction from the surface. The personal care product preferably has a substrate having a deposit that is deposited in at least a portion of the groove and forms a three-dimensional pattern. In the personal care product, it is preferable that the surface of the substrate and the surface of the deposit have a difference in height in the depth direction of the groove.

[0008] A manufacturing method according to one embodiment of the present invention is a method for manufacturing personal care products applicable to the human body.

The manufacturing method preferably includes a deposit formation step in which a depositing composition is discharged from a nozzle into the groove to deposit a deposit that forms a three-dimensional pattern. In the groove formation step, it is preferable to set up a substrate coordinate system in which the plane parallel to the stage is the XY plane and any point on the substrate surface is the substrate origin, and to form the groove with respect to the substrate origin. In the deposit formation step, it is preferable to set up a substrate coordinate system in which the plane parallel to the stage is the XY plane and any point on the substrate surface is the substrate origin, set up a second local coordinate system on a plane parallel to the XY plane with the tip of the nozzle as the origin, the XY coordinate origin of the second origin of the second local coordinate system coincides with the XY coordinate origin of the origin of the substrate coordinate system, and form the deposit within the second local coordinate system with the second origin of the second local coordinate system as the reference.

[0009] A manufacturing method according to one embodiment of the present invention is a method for manufacturing personal care products applicable to the human body. The manufacturing method preferably includes a depositional body formation step in which at least two or more depositional compositions are discharged from multiple nozzles onto the surface of a substrate to deposit a depositional body that forms a three-dimensional pattern. In the aforementioned deposition formation step, it is preferable to set up a substrate coordinate system in which the plane parallel to the stage is the XY plane and any point on the substrate surface is the substrate origin. In the deposit formation step, it is preferable to set up a plurality of local coordinate systems on a plane parallel to the XY plane, with each nozzle tip of the nozzle as the origin, and deposit the deposit within each local coordinate system based on the origin of the plurality of local coordinate systems, such that the XY coordinate origin of the origin of the plurality of local coordinate systems coincides with the XY coordinate origin of the substrate origin.

Mode for Carrying Out the Invention

[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1. Manufacturing apparatus The manufacturing apparatus 1 according to an embodiment of the present invention is a manufacturing apparatus for a personal care product 710 applicable to the human body. The personal care product 710 can be applied to the human body by directly applying it onto the skin, or by applying, spraying, dripping, etc. a liquid obtained by dissolving or dispersing it in a liquid medium such as water. The personal care product may also be one that applies fragrance to the human body, for example, an aromatherapy candle that gives a relaxation effect to the human body through fragrance. Such personal care products 710 include, for example, one or more selected from cosmetics, aromatherapy candles, detergents, and bath agents. Cosmetics include makeup cosmetics, base cosmetics, perfumes, hair care products, etc. Detergents include shampoos, soap bars, and solid soaps. Makeup cosmetics include eye shadows and foundations containing cosmetic powders, etc., and solid cosmetics such as lipsticks containing oils, etc. From the viewpoint of enabling three-dimensional molding, the personal care product 710 is preferably solid at 1 atmosphere and 20°C.

[0014] The personal care product 710 manufactured using the manufacturing apparatus 1 is typically a solid personal care product 710 mainly composed of powders such as powder cosmetics such as eye shadows or foundations containing cosmetic powders, etc. The manufacturing apparatus 1 produces personal care products 710 by introducing one or more deposition compositions into a substrate filled in a workpiece 700 to form a deposit. The deposition compositions are typically fluid. The deposition composition having fluidity is preferably a liquid itself or contains a liquid. Examples of such deposition compositions include a dispersion (so-called slurry) which is a mixture containing a powder such as a cosmetic and a liquid dispersion medium, a solution obtained by dissolving various compounds such as cosmetics in a liquid solvent, or a molten liquid obtained by heating and melting a cosmetic or oily substance alone or a composition containing a cosmetic.

[0015] Manufacturing apparatus 1 typically includes a control device and multiple (N) work machines. For example, it may include a control device 300, a first machine 500, and a second machine 600. An example of this is shown in Figure 1. The first machine 500 has means for forming grooves in the base material filled in the workpiece 700 placed on the mounting table 702. Means for forming grooves include pressing using a die or cutting. Means for cutting can be cylindrical rods or pipes, etc., and are not particularly limited, but it is preferable to have a cutting tool (for example, an end mill, drill, milling cutter, laser, or other processing tool). Hereafter, when referring to cutting tools, it is intended to broadly include cylindrical rods or pipes, etc. The first machining step performed by the first machine 500 is preferably, for example, a groove formation step. In the groove formation step, it is preferable to form grooves on the surface of the substrate by cutting the surface of the substrate with the cutting tool while moving at least one of the cutting tool and the workpiece 700 placed on the mounting table 702 relative to the other. The shape of the grooves in plan view is typically linear.

[0016] The second machine 600 is preferably a dispenser having a nozzle (processing tool) for dispensing a fluid deposition composition. The second processing step performed by the second machine 600 is preferably, for example, a deposit formation step. The deposit formation step preferably involves decorating the substrate by discharging a fluid depositing composition from the nozzle while moving at least one of the workpiece 700 placed on the nozzle and the mounting table 702 relative to the other, thereby depositing a deposit on at least a portion of the grooves formed in the substrate. The deposit forms a three-dimensional pattern. The planar shape of the deposit is typically linear. This linearity may be continuous or partially broken. The workpiece 700 subjected to the groove formation step and the deposit formation step is a precursor of a personal care product. The groove formation step and the deposit formation step involve cutting or depositing a composition onto the workpiece 700 containing a substrate, thereby forming grooves or deposits in the substrate.

[0017] Moving at least one of the processing tool and the workpiece 700 placed on the mounting table 702 relative to the other means, for example, that the workpiece 700 is mounted on the XY stage (mounting table 702) and either the processing tool or the mounting table 702 is moved. Alternatively, it means that the workpiece 700 is mounted on the shuttle (mounting table 702) of a magnetic levitation linear conveyor and either the processing tool or the mounting table 702 is moved. In this embodiment, the manufacturing apparatus 1 may be implemented by an XY stage, a magnetic levitation linear conveyor, or another apparatus.

[0018] Thus, in this embodiment, the deposit is deposited in grooves formed in the base material by pressing, or in grooves formed by cutting the base material rather than on the uncut flat surface of the base material, thereby preventing the deposit from falling off the base material and improving the aesthetic quality. In other words, in this embodiment, it is preferable that the grooves and the deposit have substantially the same shape. In the following embodiments, the base material is a dry-molded product made from a base material composition containing only powder and oil, and is manufactured by supplying the base material composition, which is the powder raw material, from a hopper or the like and molding it. On the other hand, the deposition composition is a slurry (a dispersion liquid which is a mixture containing powder such as cosmetics and a liquid dispersion medium) at the time of manufacture. On the other hand, the deposition in the finished personal care product 710 has a different composition from the slurry because the solvent contained in the slurry volatilizes, etc. In this embodiment, when we refer to the "deposition," we mean a deposition that is based on the slurry, which is the deposition composition, but has a different composition from the slurry. The slurry, which is the material for the deposition, is referred to as the "deposition composition." In another embodiment, the base material composition may be supplied as a slurry during manufacturing, similar to the deposition composition. That is, the base material is not limited to dry-molded products, but may also be wet-molded products. Furthermore, the base material composition and the deposition composition may be oily bulk materials (such as lipstick) that are heated to fluidize and then solidified after cooling.

[0019] The substrate and the deposit may be the same, but are typically different. When the substrate and the deposit are different, typically they differ in color. Specifically, this difference in color means that one or more of the following are different: lightness, saturation, hue, color (due to the composition of pearls, etc.), and texture. The substrate and the deposit may also differ in the particle size and composition of the contained particles. The difference in color improves the visibility and aesthetic appeal of the deposit 730. Three-dimensional patterns may include, for example, Japanese characters such as hiragana and katakana, various characters such as the alphabet, Arabic numerals, Roman numerals, and characters of other countries, straight lines and curves, and figures, geometric shapes, symbols, colors, patterns, or patterns of combinations thereof.

[0020] The control device 300 controls the manufacturing apparatus 1, typically by having the CPU load a computer program stored in ROM into RAM and execute it. The manufacturing apparatus 1 here typically includes a first machine 500 and a second machine 600. It is also assumed that the manufacturing apparatus 1 is an XY stage or a magnetic levitation linear transport device, with the first machine 500 having a cutting function and the second machine 600 having a dispenser function. Preferably, the control device 300 controls the first machine 500 and the second machine 600 based on an NC program using G-code as a subroutine of the basic computer program described above. The on / off state and current values ​​of the first machine 500 and the second machine 600 are controlled by G-code. The control device 300 can control the first machine 500 to execute one of several different first programs, and control the second machine 600 to execute one of several different second programs. For example, the control device 300 can cause the first machine 500 to cut grooves of different shapes (different patterns) based on different first programs (NC programs). The control device 300 can cause the second machine 600 to deposit deposits of different shapes (different patterns) based on different second programs (NC programs). Furthermore, if the first machine 500 and the second machine 600 are fixed and the mounting platform 702 moves relative to the first machine 500 and the second machine 600, the control device 300 controls the mounting platform 702 to move. The control device 300 performs a method for manufacturing a personal care product applicable to the human body. The method for manufacturing a personal care product may include the steps of forming grooves in a workpiece 700 and forming deposits in the workpiece 700. More specifically, the method for manufacturing a personal care product may include the steps of forming grooves by cutting a substrate within the workpiece 700 while moving at least one of the cutting machine and the workpiece 700 relative to the other, and depositing a deposition composition onto the substrate by introducing a deposition composition from a nozzle into the workpiece 700 while moving at least one of the nozzle and the workpiece 700 relative to the other, thereby forming a deposit that forms a three-dimensional pattern. The groove formation step and the deposit formation step each set up a substrate coordinate system in which the plane parallel to the stage is the XY plane and any point on the surface of the substrate is the origin. In each groove formation step and deposit formation step, a local coordinate system is set up on a plane parallel to the XY plane with the tip of the cutting machine or nozzle (working machine) as the origin. In the groove formation process, at least one of the cutting machine and the workpiece 700 is moved relative to the other so that the origin of the local coordinate system coincides with the origin of the substrate coordinate system. Then, the NC program is operated in the local coordinate system to form the grooves. In the deposit formation process, at least one of the nozzle (working machine) and the workpiece 700 is moved relative to the other so that the origin of the local coordinate system coincides with the origin of the substrate coordinate system. Then, the NC program is operated in the local coordinate system to form the grooves.

[0021] 2. Examples of specifications for the first and second machines Figure 2 shows examples of specifications for the first and second machines. The Z-direction travel range D2 of the cutting tool of the first machine 500 is not particularly limited, but is, for example, 50 mm. The travel range D2 refers to the range of motion (movable stroke) in the Z-direction. The distance D3 from the tip of the cutting tool to the surface 723 of the base material 720 is not particularly limited, but from the viewpoint of suppressing contact between the cutting tool and the base material, it is preferably 0.1 mm or more, more preferably 0.15 mm or more, and even more preferably 0.2 mm or more. Furthermore, while the distance D3 is not limited as long as it is within the range of the movement width D2 in the Z direction, from the viewpoint of preventing excessive time required for movement in the Z direction, it is preferably 25 mm or less, more preferably 20 mm or less, and even more preferably 15 mm or less. The cutting depth D7, that is, the distance from the surface 723 of the base material 720 to the bottom surface 724 of the groove 721, is preferably 0.05 mm or more, more preferably 0.1 mm or more, from the viewpoint of improving visibility due to shading and improving three-dimensionality. Furthermore, from the viewpoint of avoiding contact with the metal plate, D7 should be less than or equal to the value obtained by subtracting the thickness of the metal plate 701 from the filling height D5 of the base material 720 of the workpiece 700, and from the viewpoint of productivity, it is preferably 3 mm or less, more preferably 2.5 mm or less, and even more preferably 2 mm or less. For example, the cutting tool diameter corresponds to the width of the groove 721 if it is linear. From the viewpoint of realizing fine groove machining, suppressing cracking of the base material, and productivity, the cutting tool diameter is preferably 0.1 mm or more, more preferably 0.2 mm or more, and even more preferably 0.3 mm or more. In practice, the lower limit of the cutting tool diameter is 5 mm or less, preferably 4 mm or less, and more preferably 3 mm or less. The cutting tool diameter refers to the diameter of the rotating blade attached to the cutting tool. For example, it is the radial dimension set according to the shape and type of the rotating blade. For example, in a square-type end mill where the rotational trajectory of the rotating blade is cylindrical, the diameter of the rotating blade is the diameter of the rotating blade. In an end mill where the shape of the outer periphery of the rotating blade is tapered, the diameter of the rotating blade is the diameter of the tip of the rotating blade. In an end mill where the tip of the rotating blade is ball-shaped, the diameter of the rotating blade is, for example, the diameter of the ball. In an end mill for V-groove machining where the tip of the rotating blade is configured in a cone shape, the diameter of the rotating blade is, for example, the large diameter of the tip (the maximum diameter of the rotating blade). In short, for tools with a changing diameter, it refers to the part that actually contacts the base material (actual cutting diameter). Also, if the cutting tool is a drill, the diameter of the rotating blade is, for example, the diameter of the drill. If the cutting tool of the first machine 500 is an end mill, its rotational speed is, for example, 2000 rpm. The scanning speed is, for example, 12 mm / s.

[0022] It is preferable to supply the deposition composition while maintaining the coating distance H1 of the nozzle of the second machine 600 (the distance from the tip of the nozzle to the bottom surface 724 of the groove portion 721 to be coated) in such a way that the ratio of H1 to the nozzle diameter D1 (distance H1 / nozzle diameter D1) is in a predetermined relationship. More specifically, the ratio of the coating distance H1 to the nozzle diameter D1 (H1 / D1) is preferably 0.35 or more, more preferably 0.5 or more, and even more preferably 0.7 or more, from the viewpoint of preventing the discharged deposition from being crushed by the nozzle and achieving a fine line width. Furthermore, from the viewpoint of good followability of the discharged deposit with respect to the relative movement of the nozzle and the substrate, it is preferably less than 3, more preferably 2.5 or less, and even more preferably 2 or less. The above-mentioned H1 / D1 may be maintained to be constant from the start to the end of coating, or it may vary within the above range. Furthermore, while the coating distance H1 described above can be within the range described above, from the viewpoint of suppressing contact between the nozzle and the substrate, it is preferably 0.15 mm or more, more preferably 0.2 mm or more, and even more preferably 0.25 mm or more. Furthermore, from the viewpoint of improving the ability of the discharged deposit to follow the relative movement of the nozzle and the substrate, the diameter is preferably 5 mm or less, more preferably 2.5 mm or less, and even more preferably 2 mm or less.

[0023] For example, when the coating distance is 0.4 mm, the distance D4 from the tip of the nozzle to the surface 723 of the substrate 720 may be 0.3 mm, and the distance from the surface 723 of the substrate 720 to the bottom surface 724 of the groove 721 may be 0.1 mm. The nozzle diameter D1 of the nozzle of the second machine 600 is preferably 0.01 mm or more and 2 mm or less. From the viewpoint of suppressing nozzle clogging, stabilizing continuous discharge, and preventing pressure loss, D1 is preferably 0.01 mm or more, more preferably 0.1 mm or more, and even more preferably 0.2 mm or more, expressed as the length of the internal space. Furthermore, the nozzle diameter D1 described above is preferably 2 mm or less, more preferably 1 mm or less, and even more preferably 0.6 mm or less, from the viewpoint of achieving fine coating and suppressing liquid dripping. Note that the nozzle diameter D1 described above is synonymous with the inner diameter when the nozzle is circular, i.e., the length of the nozzle's cross-section. This makes it possible to manufacture personal care products with intricate three-dimensional designs, such as narrow, tall, and three-dimensional patterns, and to apply high-definition patterns to the surface. The filling height D5 of the base material 720 of the workpiece 700 is, for example, 3.55 mm. A fixing member 711, such as double-sided tape or a rubber sheet, may be provided between the metal plate 701 and the mounting base 702 of the workpiece 700. If the fixing member is double-sided tape, the distance D6 between the metal plate 701 and the mounting base 702 is, for example, 0.1 mm or more, and the distance may vary depending on the substances attached to the double-sided tape.

[0024] 3. Manufacturing method Preferably, the control device 300 controls the first machine 500 to perform the groove formation process and form the grooves 721. For example, it is preferable to control the first machine 500 to execute one of a plurality of different first programs to perform the groove formation process and form grooves 721 having a shape corresponding to the executed first program (step S1). The groove formation process is a process of forming grooves 721 that are recessed in the thickness direction from the surface 723 in the base material 720 constituting the personal care product. The grooves are typically linear. Specifically, it is preferable that the groove formation process is a process of setting a base material coordinate system in which the plane parallel to the XY stage (mounting table 702) is the XY plane and any point on the surface 723 of the base material 720 is the base material origin Ob (Figure 8), and forming the grooves 721 with respect to the base material origin Ob. An example of this flow is shown in Figure 3.

[0025] In the groove formation process, it is preferable to set up a first local coordinate system in a plane parallel to the XY plane (or XY stage) with the tip of the cutting tool of the first machine 500 as the first origin Oc. The XY coordinate origin of the first origin Oc coincides with the XY coordinate origin of the base material origin Ob of the base material 720. In the groove formation process, the groove 721 is formed within the first local coordinate system with respect to the first origin Oc. The groove formation process, when forming grooves by cutting, is performed while moving at least one of the cutting tool of the first machine 500 and the base material 720 relative to the other. At that time, the surface 723 of the base material 720 is cut by the cutting tool of the first machine 500 within a first local coordinate system with respect to the first origin Oc. This forms the groove 721. An example of this is schematically shown in Figures 4 and 8. Figure 4 is a plan view, and Figure 8 is a perspective view thereof. The groove formation process (step S1) may be carried out by press molding instead of cutting. In this case, the groove formation process can be carried out by setting up a base material coordinate system in which the plane parallel to the XY stage (mounting table 702) is the XY plane and any point on the surface 723 of the base material 720 is the base material origin Ob, and then positioning the press die 510 with respect to the base material origin Ob to form the groove 721. An example of this is schematically shown in Figure 7. By forming the groove 721 within a first local coordinate system based on a first origin Oc where the XY coordinate origins of the substrate 720's origin Ob coincide, it is possible to suppress the displacement of the groove 721 relative to the substrate origin Ob of the substrate 720.

[0026] Preferably, the control device 300 controls the second machine 600 to execute one of a plurality of different second programs, thereby executing the deposit formation process and depositing a deposit 730 having a shape corresponding to the executed second program (step S2). The deposit formation process involves discharging a deposit composition constituting the personal care product from the nozzle of the second machine 600 into at least a portion of the groove 721 to deposit a deposit 730 that forms a three-dimensional pattern, thereby decorating the base material 720.

[0027] In the sediment formation process, it is preferable to set up a second local coordinate system in a plane parallel to the XY plane (or XY stage), with the tip of the nozzle of the second machine 600 as the second origin Od. The XY coordinate origin of the second origin Od coincides with the XY coordinate origin of the substrate origin Ob of the substrate 720. In the sediment formation process, the sediment 730 is deposited within the second local coordinate system with the second origin Od as the reference. Specifically, the deposit formation process is carried out by moving at least one of the nozzle of the second machine 600 and the substrate 720 relative to the other, such that the tip of the nozzle of the second machine 600 is aligned with at least a portion of the groove 721. At that time, the deposit composition is discharged from the nozzle of the second machine 600 within a second local coordinate system with respect to the second origin Od.

[0028] By depositing the sediment 730 within a second local coordinate system based on a second origin Od where the XY coordinate origins of the substrate 720's origin Ob coincide, it is possible to suppress the displacement of the sediment 730 relative to the substrate origin Ob of the substrate 720. In this way, it is preferable to execute the first program for realizing the groove formation process in a first local coordinate system based on a first origin Oc, where the XY coordinate origin of the substrate origin Ob coincides with the XY coordinate origin of the substrate origin Ob, by setting a substrate coordinate system where the plane parallel to the XY stage (mounting base 702) is the XY plane and any point on the surface 723 of the substrate 720 is the substrate origin Ob. It is preferable to execute the second program for realizing the deposit formation process in a second local coordinate system based on a second origin Od, where the XY coordinate origin of the substrate origin Ob coincides with the XY coordinate origin of the substrate origin Ob. By doing so, positional displacement during groove formation and deposit formation can be suppressed. In addition, a common operation program can be executed by simply changing the coordinate system setting, reducing the program creation burden. Furthermore, by similarly adding a third and fourth system, more complex designs and decorations with multiple different colors can be manufactured with operations that suppress positional displacement.

[0029] Figure 5 schematically shows a comparative example of the manufacturing method. Assuming that a first program for groove formation and a second program for sediment formation are executed based on the origin O of a single coordinate system, not a local coordinate system, then design changes or changes in equipment configuration will necessitate modifications to both the first and second programs based on the origin O. In contrast, in this embodiment, the first program and the second program are each executed based on a base material coordinate system in which the plane parallel to the XY stage (mounting base 702) is defined as the XY plane, and any point on the surface 723 of the base material 720 is defined as the base material origin Ob. The first and second local coordinate systems are executed based on the first and second local coordinate systems in which the XY coordinate origins of the base material origin Ob coincide. As a result, the XY coordinate systems of the first and second programs can be made common, reducing the program load, and operation is possible with only the origin setting adjustment required.

[0030] The first origin of the first local coordinate system of the first program and the second origin of the second local coordinate system of the second program can be made common. In this case, the first origin Oc of the first local coordinate system and the second origin Od of the second local coordinate system coincide. Therefore, the first origin Oc and the second origin Od do not necessarily have to coincide with the base material origin Ob. This reduces the program load compared to the case where the first local coordinate system and the second local coordinate system of the second program are different. An example of this is schematically shown in Figure 6.

[0031] 4. Specific examples of personal care products The personal care product 710 manufactured by the manufacturing apparatus 1 typically comprises a base material 720 and a deposit 730. The base material 720 typically has grooves 721 that are recessed in the thickness direction from the surface 732. It is preferable that the sediment is deposited in at least a portion of the groove 721, forming a three-dimensional pattern. Typically, the surface 723 of the base material 720 and the surface 732 of the deposit 730 have a height difference in the depth direction (Z direction) of the groove 721. By forming the deposit 730 in at least a portion of the groove 721, the contact area of ​​the deposit 730 with the base material 720 increases, making it less likely for the deposit 730 to fall off and improving the three-dimensional appearance. Figures 9 and 10 schematically show cross-sections of personal care products.

[0032] It is preferable that the groove 721 has a deposit 730 in at least a portion of its cross-section along its width. In addition, it is preferable that the groove has a gap 722 in another portion, or an overhang 731 adjacent to the groove 721, or both. In a cross-section along the width direction of the groove 721, a portion may have a deposit 730, while the other portion where the deposit 730 is not deposited may have a gap 722. A deposit 730 is placed in the groove 721, and in adjacent parts in the width direction of the groove 721, the portion where at least a part of the deposit 730 is deposited on the surface 723 of the base material 720 is the protruding portion 731. This makes the boundaries of the sedimentary mass 730 more visible due to the shading, and enhances the sense of three-dimensionality. In particular, the presence of the protruding portion 731 creates an anchoring effect, making it easier to maintain quality. An example of this is shown in Figure 9.

[0033] The ratio of the height of the deposit 730 in the depth direction of the groove 721 to the depth of the groove 721 is preferably 0.01 or more and 100 or less. From the viewpoint of emphasizing shading due to height differences and enhancing three-dimensionality, as well as the decorative properties and productivity of the deposit in the groove and suppression of collapse of the decorative part by the deposit, the ratio of the height of the deposit 730 in the depth direction to the depth of the groove 721 is preferably 0.01 or more and 0.99 or less and 1.01 or more and 100 or less, more preferably 0.1 or more and 0.9 or less and 1.1 or more and 90 or less, and even more preferably 0.2 or more and 0.8 or less and 2 or more and 50 or less. There may be variations in the depth of the groove 721 and / or the height of the deposit 730. The deposit 730 may be embedded in the groove 721 and lower than the surface 723 of the base material 720, or the deposit 730 may be raised above the surface 723 of the base material 720. An example of this is shown in Figure 10.

[0034] When decorating the surface of a substrate by forming three-dimensional patterns using press processing with molds, the production of molds is time-consuming and costly, resulting in a large initial investment and a long development period. Therefore, it is difficult to manufacture a wide variety of personal care products that require frequent design changes and customization. In contrast, according to the manufacturing method of the present invention, a deposit 730 is formed in at least a portion of the groove 721 of the base material 720 by discharge from a nozzle of the second machine 600. As a result, it is possible to avoid using a mold to form the deposit, making it possible to create three-dimensional designs that are difficult to create with a mold, and allowing for high-precision changes to line widths, etc. Since a mold is not required, investment can be reduced and the development period (lead time) can be shortened. Since the design can be changed by changing the program, it is possible to manufacture a wide variety of personal care products from a single unit, and the design can be easily changed, making it easy to respond to needs such as customization. In the case of a personal care product 710 with a decorative surface, it is possible to provide a personal care product 710 in which the decorative design is precise and high-precision.

[0035] 5. Example of a second machine The second machine 600 typically includes a supply unit 20 for supplying a fluid depositing composition L onto a workpiece 700, and a nozzle 21 integrally disposed to communicate with the supply unit 20. The depositing composition L is the material for the deposit. Typically, a flat mounting table 702 is positioned below and opposite the nozzle 21, and the workpiece 700 can be mounted on the upper surface of the mounting table 702. An example of this is shown in Figure 11. The second machine 600 supports or holds the supply unit 20 and the mounting table 702 in predetermined positions. The second machine 600 moves the position of the nozzle 21 and the position of the mounting table 702 relative to each other in any direction. This allows at least one of the nozzle 21 and the mounting table 702 to be moved in a planar direction, a vertical direction, or a combination thereof, thereby moving at least one of the workpiece 700 on the nozzle 21 and the mounting table 702 relative to the other.

[0036] The supply unit 20 is a component that delivers a fluid deposit composition L to the workpiece 700. Preferably, the supply unit 20 comprises a liquid delivery unit 25 and a composition storage unit 26. Preferably, the liquid supply unit 25 is connected to the composition storage unit 26 via a flow path 28. This allows the deposit composition L supplied from the composition storage unit 26 to the liquid supply unit 25 to be supplied continuously or discontinuously to the nozzle 21 side, or the supply to be stopped. As such a liquid supply unit 25, a jet dispenser capable of dispensing the deposit composition L in droplet form, or a mono dispenser or screw dispenser capable of continuously dispensing the deposit composition L can be used.

[0037] Preferably, one end of the composition storage section 26 is connected to a pressurizing means such as air or a pump, and the composition L for deposition stored in the composition storage section 26 is configured to be pressurized and sent to the liquid supply section 25 side via the flow path 28. The nozzle 21 is typically a tubular member that supplies the deposition composition L from the supply unit 20 to the workpiece 700. The nozzle 21 has a flow path for the deposition composition L, which is a space formed inside it, and the flow path is formed along the direction of the deposition composition L. One end of the nozzle 21, the nozzle tip, constitutes the supply port for the deposition composition L, and the other end is connected in communication with the supply unit 20 described above. The material of the nozzle is not particularly limited, and for example, metal or plastic can be used.

[0038] 6. Examples of deposition compositions Unless otherwise specified, the states of matter (three states) described below are based on 1 atmosphere and 20°C. Furthermore, compositions may use three or more elements. The deposition composition has a viscosity of preferably 0.1 Pa·s or higher, more preferably 0.5 Pa·s or higher, and even more preferably 1 Pa·s or higher, from the viewpoint of improving the uniform dispersion of the materials contained in the deposition composition and stabilizing its quality, as well as suppressing the collapse of the deposited material discharged from the nozzle and stabilizing its shape. The viscosity is preferably 1000 Pa·s or less, more preferably 500 Pa·s or less, and even more preferably 200 Pa·s or less, from the viewpoint of improving dischargeability and moldability. The viscosity of the deposition composition described above is measured after the temperature of the deposition composition is set to the same temperature as the deposition composition supplied from the nozzle 21, i.e., the temperature at which it is discharged. For example, if the deposition composition is not a heated molten liquid, such as a slurry, and is supplied from the nozzle at room temperature (25°C), the value measured at 25°C using a Type B viscometer (Toki Sangyo Co., Ltd., digital viscometer TVB-10R) shall be used. In this case, the measurement conditions shall be to set the rotor to one of rotor No. M1, M2, M3, M4, H1, H2, H3, H4, H5, H6, H7, TA, TB, TC, TD, and TE according to the viscosity range of the sample, with a rotation speed of 3 to 100 rpm and a measurement time of 60 seconds. If the deposition composition is a heated molten liquid, the viscosity is measured under the above measurement conditions after the temperature of the deposition composition is set to the same temperature as the deposition composition supplied from the nozzle 21.

When measuring the average particle size of the powder from the final product, the product is first dissolved in water or oil to dissolve the binder components and disperse the particles in the solvent. Then, the particle size distribution as a solid is measured using a particle size distribution analyzer, and the resulting volume cumulative particle size D50 is taken as the average particle size. The average particle size of the powder in the deposition composition is preferably smaller than the nozzle diameter D1 of the nozzle 21, from the viewpoint of stable supply from the nozzle.

Figure 12(b) shows an example where the nozzle 21 is rectangular, and Figure 12(c) shows an example where the nozzle 21 is elliptical. From the viewpoint of making the line width W1 in a plan view of the deposition body produced by the above method thinner and stably forming a three-dimensional and high-definition design, the ratio of the average particle size of the powder in the deposition composition to the nozzle diameter D1 of the nozzle 21 (average particle size / nozzle diameter) is preferably 1 or less, more preferably 0.5 or less, even more preferably 0.35 or less, and even more preferably 0.3 or less.
