[0036] In the techniques described in Patent Documents 1 and 2, a pattern is formed on the surface of a cosmetic material (a cosmetic material for the lower layer in Patent Document 2) by ejecting a cosmetic material constituting a pattern from a nozzle. That is, in the techniques described in Patent Documents 1 and 2, the pattern itself is formed by drawing the outline of the pattern. Therefore, in the techniques described in Patent Documents 1 and 2, it is difficult to give light and dark to the pattern.

[0037] The technology of Patent Document 3 can express light and dark colors, but it is difficult to express three-dimensional patterns.

[0038] The technology of Patent Document 4 is a technology for producing a relief pattern on securities such as stocks, and Patent Document 4 does not include any research on forming a pattern on a solid personal care product.

[0039] The present invention relates to a solid personal care product having a three-dimensional pattern capable of expressing light and dark colors.

[0040] Hereinafter, the present invention will be described based on preferred embodiments thereof.

[0041] The solid personal care product of the present invention preferably has a base portion 10 and a line portion 20 formed on a surface 10a of the base portion 10. Specifically, the solid personal care product preferably includes a body portion 11 having the base portion 10 and the line portion 20.

[0042] The linear portion 20 preferably has a three-dimensional shape. Specifically, the linear portion 20 is preferably provided so as to protrude from the surface 10 a of the base portion 10 .

[0043] The solid personal care product preferably has only one line portion 20. In other words, the line portion 20 is formed in a linear shape. In this case, the line portion 20 is also preferably in a spiral shape that can be drawn with one stroke.

[0044] A typical example of a solid personal care product is a cosmetic. The cosmetic 1 preferably comprises a main body 11 and a container 30 in which the main body 11 is housed. Figure 1 shown.

[0045] The three-dimensional line portion 20 is a convex portion formed on the surface 10a of the base portion 10. Figure 4 shown.

[0046] In addition, the solid personal care product may also have more than two plurality of line portions 20. In other words, the line of the line portion 20 may also be partially interrupted.

[0047] In the solid personal care product of the present invention, it is preferred that the width W of the line portion 20 changes along the length direction of the line portion 20. The width W of the line portion 20 may change continuously or in stages along the length direction of the line portion 20. In addition, the width W of the line portion 20 is preferably along at least one direction X (see FIG. 1 ) parallel to the surface 10a of the base portion 10. Figure 2 The width W of the line portion 20 may be changed continuously along one direction X, or may be changed in stages. Figure 1 to Figure 3 Indicated in.

[0048] In the illustrated example, the width W of the line portion 20 changes continuously along the length direction of the line portion 20 .

[0049] In the example shown in the figure, the line portion 20 has both a portion where the width W changes continuously along one direction X and a portion where the width W changes stepwise along the one direction X.

[0050] In the solid personal care product of the present invention, the line portion 20 preferably includes a portion 20a having a wider width W (hereinafter also referred to as a "wide width portion") and a portion 20b having a narrower width W (hereinafter also referred to as a "narrow width portion"). The width mentioned here is relative to the other. The line portion 20 preferably includes a plurality of wide width portions 20a and narrow width portions 20b.

[0051] The solid personal care product typically has a wide portion 20a and a narrow portion 20b in a specific configuration, and when viewed from above or obliquely from above the surface 10a of the base 10, a dense-dense structure having a dense portion 21 and a sparse portion 22 is formed. The dense portion 21 is a portion where the linear portion 20 is densely present on the surface 10a of the base 10, that is, a portion where the wide portion 20a is present. The sparse portion 22 is a portion where the linear portion 20 is sparsely present, that is, a portion where the narrow portion 20b is present.

[0052] Specifically, for example, when the surface 10a of the base portion 10 is observed along one direction X, the sparse portions 22 and the dense portions 21 are alternately arranged. The sparse portions 22 are portions where the ratio of the area S1 occupied by the linear portions 20 per unit area S0 when viewed from above or obliquely from above is relatively small. The dense portions 21 are portions where the ratio of the area S1 occupied by the linear portions 20 per unit area S0 when viewed from above or obliquely from above is relatively large. The one direction X may be any direction parallel to the surface 10a of the base portion 10.

[0053] Their specific examples are Figure 3 and 4 Indicated in.

[0054] As described above, the solid personal care product of the present invention is preferably such that, when the surface 10a of the base 10 is viewed from above or obliquely from above, the ratio S1 / S0 of the occupied area S1 occupied by the linear portion 20 per unit area S0 changes along one direction X. The ratio S1 / S0 of the occupied area is not limited to one direction X, but more preferably changes along any direction parallel to the plane of the base 10. That is, it is preferred that the change in the occupied area S1 can be observed at any viewing angle relative to the surface of the solid personal care product.

[0055] When any direction parallel to the plane of the base portion 10 is the length direction of the line portion 20, the occupied area S1 changes with the change in the width W. In this case, the change in the ratio of the above-mentioned exclusive area occurs at the change point N where the width W of the line portion 20 changes, for example, a line connecting a plurality of change points N becomes a boundary between a dense portion and a sparse portion, and is recognized as a subjective contour.

[0056] Whether the above-mentioned occupied area ratio S1 / S0 changes along one direction parallel to the surface 10 a of the base portion 10 can be determined by the following method.

[0057] <Judgment method>

[0058] First, an imaginary line along one direction parallel to the surface 10a of the base 10 is assumed. The one direction may be any direction parallel to the surface 10a. Then, when the surface 10a of the base 10 is observed along the one direction, if there are dense and sparse parts of the line part on the surface 10a, that is, if a sparse-dense structure is formed, it is judged that the ratio S1 / S0 of the occupied area changes along the one direction.

[0059] At least in the following cases (1) to (4), it is determined that there are dense portions and sparse portions in the line portion.

[0060] (1) When the line portion has a portion (dense portion) where the lines are close to each other and thus exist at a relatively high density, and a portion (sparse portion) where the lines are separated from each other by a long distance and thus exist at a relatively low density.

[0061] In this case, it is preferred that the line portion has a relatively wide portion, i.e., a wide width portion, and a relatively narrow portion, i.e., a narrow width portion, so that the interval between the line portions changes. The line portion having the wide width portion and the narrow width portion may be a continuous line portion (see Figure 1 ), or may be a plurality of discontinuous line portions. Preferably, the plurality of line portions (e.g., 2 to 20) arranged side by side have a portion with a changed width, such as a portion with an increased or decreased width, at the same position or a position close to the position in the extending direction thereof (see Figure 1 ). Figure 3 N represents the portion where the width is reduced.

[0062] (2) When the line portion has a relatively high portion, i.e., a high portion, and a relatively low portion, i.e., a low portion

[0063] In this case, when viewed from above, shadows appear more in the high part, which is recognized as a high-density existence of the line part, and thus becomes a dense part. Relatively few shadows appear in the low part, which is recognized as a low-density existence of the line part, and thus becomes a sparse part. In the case of (2), it is preferred to have a part where high parts exist relatively at a high density (high-existence part of the high part) and a part where high parts exist relatively at a low density (low-existence part of the high part).

[0064] (3) There are parts where the degree of curvature of the line portion is large and the total length of the line portion contained in a certain area is long, and parts where the degree of curvature of the line portion is small and the total length of the line portion contained in a certain area is short (refer to Figure 8 , Fig. 9 (a) and (b))

[0065] (4) Combination of (1) to (3)

[0066] The above-mentioned occupied area ratio S1 / S0 can be measured in the following manner.

[0067] <Method for measuring the occupied area ratio S1 / S0>

[0068] A method for measuring the above-mentioned occupied area ratio S1 / S0 in a plan view will be described.

[0069] The surface 10a of the base 10 is viewed from above, and a region of a certain area is taken as the region to be measured. The area of ​​the region to be measured is the unit area S0. In addition, the area of ​​the line portion contained in the region to be measured is measured from above. The area of ​​the line portion measured from above is the occupied area S1 occupied by the line portion. Then, the ratio S1 / S0 is calculated by dividing the occupied area S1 by the unit area S0.

[0070] Alternatively, the ratio S1 / S0 may be calculated as follows. First, an image of the surface 10a of the base portion 10 is obtained by looking down, and, for example, an arbitrary area surrounded by a 10 mm square is used as the area to be measured. The number of pixels in the area to be measured is counted, and the number of pixels obtained by the count is set to S0. Next, the number of pixels in the line portion included in the area to be measured is counted, and the number of pixels obtained by the count is set to S1. Then, the ratio S1 / S0 may be calculated by dividing the number of pixels S1 in the line portion by the number of pixels S0 in the area to be measured.

[0071] The above-mentioned area of ​​a certain area as the measurement object can be appropriately set according to the thickness and distribution of the line portion, for example, it can be a 10 mm square or 5 mm square area, or a circular area with a diameter of 10 mm or 5 mm, etc. In the case of measuring an object with higher precision, it can also be set to a 1 mm square or 0.5 mm square area, or a circular area with a diameter of 1 mm or 0.5 mm, etc.

[0072] In the solid personal care product of the present invention, it is preferred that a pattern utilizing a subjective contour is generated by changing the above-mentioned occupied area ratio S1 / S0. Specifically, it is preferred that the above-mentioned sparse and dense structure is formed on the surface 10a of the base portion 10 so that a pattern utilizing a subjective contour is generated when the above-mentioned surface 10a is visually observed.

[0073] exist Figure 1 and Figure 2 In the example shown, a star and crescent-shaped pattern is produced.

[0074] Subjective contour refers to a contour that is perceived by illusion even though there is no change in brightness or color along the contour. In other words, a contour that does not physically exist is perceived by the arrangement of surrounding stimuli. It is sometimes called an illusory contour, a cognitive contour, or a heterogeneous contour.

[0075] The subjective contour is well known in various fields of image processing (Japanese Patent Application Laid-Open No. 2010-4178, Japanese Patent Application Laid-Open No. 2005-165060, etc.).

[0076] In the solid personal care product of the present invention, a pattern using a subjective outline is generated by changing the ratio S1 / S0 of the occupied areas, that is, by forming the sparse and dense structure on the surface 10a of the base 10. Therefore, the pattern of the solid personal care product can be formed into a pattern showing light and dark colors.

[0077] The solid personal care product of the present invention has a three-dimensional pattern because the line portion 20 has a three-dimensional shape. In addition, a shadow is generated when the solid personal care product is visually viewed.

[0078] The solid personal care product of the present invention has a pattern which is produced using subjective contours and produces a shadow when viewed visually, thereby being able to make the pattern a more impressive or attractive pattern.

[0079] In this way, the solid personal care product according to the present invention can present a three-dimensional pattern with different shades.

[0080] In the solid personal care product of the present invention, the width W of the line portion 20 may be changed along one direction X or along the length direction of the line portion 20, and the height T of the line portion 20 (see Figure 4 ) along one direction X or along the length direction of the line portion 20, so as to change the above-mentioned occupied area ratio S1 / S0. In addition, the above-mentioned occupied area ratio S1 / S0 may be changed by changing both the width W and the height T of the line portion 20 along one direction X or along the length direction of the line portion 20.

[0081] By changing the width and height of the stripe 20 or both thereof along one direction X or along the length direction of the stripe 20, the above-mentioned occupied area ratio S1 / S0 can be changed, so that the shadow produced when viewed visually can be made clearer, and thus the pattern of the solid personal care product can be made more impressive or more attractive. In addition, the solid personal care product can be easily manufactured. The manufacturing method of the solid personal care product will be described later.

[0082] The width W of the stripe portion 20 in a plan view is not particularly limited, but is preferably 0.05 mm or more, more preferably 0.1 mm or more, and further preferably 0.15 mm or more from the viewpoint of forming a three-dimensional pattern and suppressing nozzle clogging by the composition.

[0083] In addition, from the viewpoint of forming a high-definition pattern, the width W of the stripe portion 20 is preferably 3 mm or less, more preferably 2 mm or less, and even more preferably 1.5 mm or less.

[0084] The fact that the width W of the line portion 20 is within the above range means that both the width of the widest portion and the width of the narrowest portion of the line portion 20 are within the above range.

[0085] When viewed from above, the ratio W2 / W1 of the width W2 of the narrowest part of the line portion 20 to the width W1 of the widest part is not particularly limited, but is preferably 1.6% or more, more preferably 2.5% or more, and even more preferably 3.3% or more from the perspective of easily identifying a pattern utilizing a subjective contour.

[0086] In addition, in view of forming a high-definition pattern, the ratio W2 / W1 is preferably 90% or less, more preferably 80% or less, and further preferably 70% or less when viewed from above. The ratio W2 / W1 is expressed as a percentage (%). The same applies to the ratio T2 / T1, the ratio D2 / D1, the ratio D / W, the ratio R2 / R1, and the ratio H2 / H1 described later.

[0087] When the line portion 20 is a convex portion as in the present embodiment, the height T of the line portion 20 is not particularly limited, but is preferably 0.05 mm or more, more preferably 0.1 mm or more, and further preferably 0.12 mm or more from the viewpoint of forming a three-dimensional pattern.

[0088] In addition, from the viewpoint of suppressing deformation of the line portion, the height T of the line portion 20 is preferably 2 mm or less, more preferably 1 mm or less, and even more preferably 0.6 mm or less.

[0089] The height T of the line portion 20 refers to the distance from the base end to the tip end of the line portion 20 in the protruding direction of the line portion 20 (see Figure 4 ).

[0090] The fact that the height T of the line portion 20 is within the above range means that both the height of the highest portion and the height of the lowest portion of the line portion 20 are within the above range.

[0091] The ratio T2 / T1 of the height T2 of the lowest part in the line portion 20 to the height T1 of the highest part is not particularly limited, but is preferably 2.5% or more, more preferably 5% or more, and further preferably 8.3% or more from the perspective of easily recognizing a pattern using a subjective contour.

[0092] From the viewpoint of forming a high-definition pattern, the ratio T2 / T1 is preferably 90% or less, more preferably 80% or less, and even more preferably 70% or less.

[0093] The distance D between adjacent line portions 20 when viewed from above is not particularly limited. In the line portion forming process described later, from the perspective of preventing the previously formed line portion 20 from contacting the nozzle 61, it is preferably greater than 0.15 mm, more preferably greater than 0.5 mm, and further preferably greater than 1 mm.

[0094] In order to easily recognize a pattern using a subjective outline and form a high-definition pattern, the distance D between adjacent line portions 20 in a plan view is preferably 15 mm or less, more preferably 10 mm or less, and even more preferably 5 mm or less.

[0095] From the perspective of easily generating a subjective outline using the uniformity of the line portions 20, the ratio D2 / D1 of the shortest distance D2 to the longest distance D1 among the distances D between adjacent line portions 20 when viewed from above is preferably greater than 5%, more preferably greater than 10%, and even more preferably greater than 20%.

[0096] In addition, from the viewpoint of easily preventing overlapping of the stripe portions 20 , the ratio D2 / D1 is preferably 100% or less, more preferably 90% or less, and even more preferably 80% or less.

[0097] The distance D between adjacent line portions 20 is measured as follows. First, it is assumed that an imaginary line L (see Figure 2 and Figure 5 ). When the cosmetic material 1 has only one line portion 20, the imaginary line L intersects with two or more locations of the line portion 20. When the cosmetic material 1 has a plurality of line portions 20, the imaginary line L may intersect with two or more locations of one line portion 20 among the plurality of line portions 20, or may intersect with two or more line portions 20. The distance along the imaginary line L between the centers of adjacent portions of the line portion 20 intersecting with the imaginary line L is set as the distance D between adjacent line portions 20. The imaginary line L is preferably orthogonal to the line portion 20, but depending on the pattern, it is sometimes impossible to set the imaginary line L orthogonal to the line portion 20, so the imaginary line L can be set at any position.

[0098] That the distance D between adjacent linear portions 20 is within the above range means that the distance D is within the above range at both a portion where the distance D is the largest and a portion where the distance D is the smallest in the linear portion 20 .

[0099] The ratio D / W of the distance D between adjacent line portions to the width W of the line portion when viewed from above is not particularly limited, but is preferably 5% or more, more preferably 7.5% or more, and even more preferably 10% or more from the viewpoint of preventing the line portion 20 formed earlier in the later-described line portion forming process from contacting the nozzle 61.

[0100] In order to easily recognize a pattern using a subjective outline and form a high-definition pattern, the ratio D / W in a plan view is preferably 5000% or less, more preferably 4000% or less, and even more preferably 3000% or less.

[0101] When calculating the ratio D / W, the average value of the width W of the line portion is taken as the width W of the line portion, and the average value of the distance D between adjacent line portions is taken as the distance D between adjacent line portions.

[0102] The solid personal care product of the present invention preferably has a laminated structure in which two or more layers are laminated, including the base portion 10 and the line portion 20. The portion having the laminated structure is preferably a portion that exerts the function of the solid personal care product when the product is used, and the portion having the laminated structure in this case is referred to as a functional portion.

[0103] exist Figure 4 In the embodiment shown, the base portion 10 and the line portion 20 are formed in different layers. That is, in this embodiment, the main body portion 11 having a laminated structure in which the base portion 10 and the line portion 20 are laminated is a functional portion.

[0104] By having a laminated structure in which two or more layers are laminated, it is possible to impart different functions to each layer, or to make the pattern of the solid personal care product more complex or easier to identify. From the viewpoint of more significantly exerting this effect, it is preferred that either or both of the components and colors of the compositions constituting the layers in the laminated structure are different.

[0105] In the case where the portion having a laminated structure has a laminated structure in which three or more layers are laminated, it may also have a plurality of layers having the same composition and color. For example, the functional portion has a laminated structure in which three layers are laminated, and two of the three layers have the same composition and color, and the two layers and the remaining one layer may have different compositions and / or colors of the composition constituting the layers, or both.

[0106] A layer different from the linear portion 20 and the base portion 10 may be disposed between the linear portion 20 and the base portion 10 .

[0107] The line portion 20 may have a laminated structure in which two or more layers are laminated, and the base portion 10 may have a laminated structure in which two or more layers are laminated.

[0108] In addition, either or both of the components and colors of the composition may be partially different in the same layer. For example, by making the color of the line portion 20 partially different, the pattern of the solid personal care product can be presented in multiple colors, thereby forming a more impressive or attractive pattern.

[0109] In the solid personal care product of the present invention, the line portion 20 is preferably formed by a layer located farthest from the layer constituting the base portion 10 in the portion having a laminated structure. Thus, the line portion 20 can be easily visually viewed, and the pattern generated by the subjective contour can be easily recognized. In the example shown in the figure, the layer located farthest from the layer constituting the base portion 10 is a layer that forms a surface on the side facing the user side when the solid personal care product is used.

[0110] Furthermore, the line portion 20 may be formed by a layer other than the layer located farthest from the layer constituting the base portion 10 in the portion having the laminated structure. In this case, it is preferred that the layer located on the opposite side of the layer forming the line portion 20 from the layer constituting the base portion 10 is transparent or translucent so that the line portion 20 can be recognized when the solid personal care product is visually viewed.

[0111] The solid personal care product of the present invention can change at least one of the hue contrast, lightness contrast and chroma contrast of the pattern according to the visual direction. The "contrast" in the hue contrast, lightness contrast and chroma contrast mentioned here means, for example, taking lightness as an example, when observing the lightness of the base portion 10 and the lightness of the line portion 20 at the same time, the lightness of the line portion 20 looks different due to the influence of the lightness of the base portion 10. More specifically, it means that when observing the base portion 10 with relatively high lightness and the line portion 20 with relatively low lightness at the same time, the lightness of the line portion 20 looks lower than the lightness of the line portion 20 itself. The same is true for hue and chroma.

[0112] The manner in which the hue contrast of the pattern changes according to the visual direction includes a manner in which the hue of the pattern of the solid personal care product looks different when observed from an arbitrary direction and when observed from a direction different from the one direction. Here, the hue change refers to a situation in which the hue on the hue wheel presented in 40 equal parts is classified according to the visual direction. In addition, the manner in which the lightness contrast of the pattern changes according to the visual direction includes a manner in which the lightness of the pattern of the solid personal care product looks different when observed from an arbitrary direction and when observed from a direction different from the one direction. In addition, the manner in which the chroma contrast of the pattern changes according to the visual direction includes a manner in which the chroma of the pattern of the solid personal care product looks different when observed from an arbitrary direction and when observed from a direction different from the one direction.

[0113] For example, Figure 6 The cosmetic material 1 shown in (a) to (c) has a pattern whose brightness contrast changes depending on the direction of viewing. Specifically, Figure 6 In the cosmetic material 1 shown, when the cosmetic material 1 is observed from the direction B, the brightness contrast of the pattern becomes relatively low (refer to Figure 6 (b)), when the cosmetic material 1 is observed from the direction C, the brightness contrast of the pattern becomes relatively high (refer to Figure 6 (c)). That is, Figure 6 When the cosmetic material 1 is observed from the B direction, the lightness of the pattern is relatively low, so the shape of the pattern is relatively difficult to identify, and when it is observed from the C direction, the lightness of the pattern is relatively high, so the shape of the pattern is relatively easy to identify. More specifically, observing from the B direction or the C direction means observing the surface of the solid personal care product having the line portion 20 from obliquely above.

[0114] As a method for changing at least one of the color contrast, lightness contrast, and chroma contrast of the pattern of the solid personal care product of the present invention according to the visual direction, there can be cited a method of improving the orientation of the line portion 20 when the solid personal care product is viewed from above.

[0115] For example, the arrangement pattern of the line portion 20 is a stripe shape (see Figure 7 In the case of (a) and (b)), the arrangement pattern of the line portion 20 is concentric with the line portion 20 (refer to Figure 7 (c)) or vortex (refer to Figure 7 Compared with the case of (d)), the orientation of the line portion 20 is high, and at least one of the color contrast, lightness contrast, and chroma contrast of the pattern is easily changed according to the visual direction. Figure 7 In (a) to (c) of FIG. 1 , for the sake of convenience of explanation, the illustration of the sparse and dense structure of the line portion 20 is omitted.

[0116] Figure 7 In the examples shown in (a) and (b) of FIG. 1 , when viewed from the A direction, the gaps between the line portions 20 are more easily recognized than when viewed from the B direction. Figure 7 In the examples shown in (a) and (b), the ease of identifying the gaps differs depending on the direction of visual observation. Therefore, at least one of the color contrast, lightness contrast, and chroma contrast of the pattern is different from the color contrast, lightness contrast, and chroma contrast of the pattern. Figure 7 Compared with the examples shown in (c) and (d), it is easier to change depending on the viewing direction.

[0117] The orientation of the line portion 20 can be quantitatively evaluated by obtaining an image when looking down at the solid personal care product and performing Fourier transform image processing. Specifically, the power spectrum is obtained by Fourier transform, and the angular distribution of the amplitude is calculated. Then, the orientation strength is calculated according to the angular distribution of the amplitude, and the orientation strength can be used as an index of orientation. The orientation strength is calculated as the major axis / minor axis ratio of the approximate ellipse in the angular distribution diagram of the amplitude. If the orientation strength is less than 1.1, it can be regarded as no orientation, if it exceeds 1.1 and is less than 1.2, it can be regarded as weak orientation, and if it is more than 1.2, it can be regarded as strong orientation.

[0118] The solid personal care product of the present invention may have only one stripe portion 20 (see Figure 1 , Figure 7 (b) and Figure 7 (d)), it may also have more than two line portions 20 (see Figure 7 (a) and Figure 7 (c)).

[0119] By having only one line portion 20, the end points of the line portion 20 can be set to only the starting point and the end point. When the composition M is discharged from the nozzle 61 in the line portion forming step described later to form the line portion 20, the end points such as the starting point and the end point are prone to unexpected changes in the width W of the line portion 20. By having only one line portion 20, it is easy to form the line portion 20 on the surface 10a of the base portion 10 as intended, and the cosmetic 1 can be easily manufactured.

[0120] In addition, by having a plurality of line portions 20, the pattern of the cosmetic 1 can be made more diverse. The line portion 20 can be a line with a starting point and an end point, or can be a ring-shaped line without a starting point and an end point. Here, the line portion 20 being a ring-shaped line without a starting point and an end point means that when the line portion 20 formed on the solid personal care product is viewed from above or from an angle above, the line portion 20 is a ring-shaped line without a starting point and an end point. The ring-shaped line portion 20 without a starting point and an end point can have, for example, an initially formed portion, i.e., a formation start point, and a last formed formation end point when the line portion 20 is formed. In the case where the solid personal care product has a plurality of line portions 20, the number of the line portions 20 is not limited.

[0121] The line portion 20 may be arranged so as not to intersect with a part of the line portion 20 or other line portions 20 different from the line portion 20 (see Figure 1 , Figure 7 (a) to (d)), it may be arranged in a manner intersecting with a part of the line portion 20 or other line portions 20 different from the line portion 20 (refer to Figure 8 ).

[0122] When the composition M is discharged from the nozzle 61 to form the line portion 20 in the line portion forming step described later, the width W of the line portion 20 is easily changed accidentally at a location where parts of the line portions 20 intersect each other or a location where the line portion 20 intersects with a line portion 20 different from the line portion. From the viewpoint of suppressing such unintentional change in the width W of the line portion 20, the line portion 20 is preferably arranged so as not to intersect with a part of the line portion 20 or other line portions 20 different from the line portion 20.

[0123] From the viewpoint of diversifying the expression method of the pattern possessed by the solid personal care product, the line portion 20 is preferably arranged so as to intersect with a part of the line portion 20 or a line portion 20 different from the line portion 20. When the line portion 20 is arranged so as to intersect with a part of the line portion 20 or a line portion 20 different from the line portion 20, the number of intersections is not particularly limited.

[0124] exist Figure 1 , Figure 7 (b) and Figure 7 In the example shown in (d) of FIG. 1 , each of the line portions 20 is arranged so as not to intersect a part of the line portion 20 .

[0125] exist Figure 7 (a) and Figure 7In the example shown in (c), each of the line portions 20 is arranged so as not to intersect with a part of the line portion 20, and each of the line portions 20 is arranged so as not to intersect with each other.

[0126] In the solid personal care product of the present invention, instead of changing the width W of the line portion 20, the line portion 20 may be bent to change the above-mentioned occupied area ratio S1 / S0 (see Fig. 9 (a)). The line portion 20 may have only one curved portion or may have a plurality of curved portions.

[0127] In addition, the ratio S1 / S0 of the occupied area may be changed by bending the line portion 20 (see Fig. 9 (b) The line portion 20 may have only one curved portion or may have a plurality of curved portions.

[0128] The occupied area ratio S1 / S0 may be changed by bending and folding the linear portion 20. The linear portion 20 may have only one bent portion and only one folded portion, may have only one bent portion and a plurality of bent portions, may have a plurality of bent portions and only one bent portion, or may have a plurality of bent portions and a bent portion.

[0129] From the perspective of simplifying the control of the width W of the line portion 20 and smoothly moving the relative position of the object 70 with respect to the nozzle 61 in the line portion forming process described later, thereby suppressing vibration when drawing the line portion, it is preferred to change the above-mentioned occupied area ratio S1 / S0 by bending the line portion 20.

[0130] From the viewpoint of simplifying the control of the width W of the stripe portion 20 and forming a high-definition pattern, it is preferable to change the above-mentioned occupied area ratio S1 / S0 by bending the stripe portion 20 .

[0131] From the viewpoint of simplifying the control of the width W of the linear portion 20 and diversifying the method of expressing the pattern, it is preferable to change the above-mentioned occupied area ratio S1 / S0 by bending and folding the linear portion 20 .

[0132] When the line portion 20 is curved, the curvature radius R of the line portion 20 when viewed from above is not particularly limited, but is preferably 0.1 mm or more, more preferably 0.2 mm or more, and further preferably 0.3 mm or more from the viewpoint of preventing the line portion discharged first from contacting the nozzle.

[0133] In order to easily recognize a pattern using a subjective outline and form a high-definition pattern, the curvature radius R of the linear portion 20 in a plan view is preferably 1000 mm or less, more preferably 800 mm or less, and even more preferably 600 mm or less.

[0134] The curvature radius R of the linear portion 20 being within the above range means that both the curvature radius of the portion with the largest curvature radius and the curvature radius of the portion with the smallest curvature radius in the linear portion 20 are within the above range.

[0135] When viewed from above, the ratio R2 / R1 of the radius of curvature R2 of the portion with the smallest radius of curvature in the line portion 20 to the radius of curvature R1 of the portion with the largest radius of curvature is not particularly limited, but is preferably 0.01% or more, more preferably 0.02% or more, and even more preferably 0.03% or more from the viewpoint of preventing the first discharged line portion from contacting the nozzle.

[0136] In order to make the pattern using the subjective outline easily recognizable and to form a high-definition pattern, the ratio R2 / R1 is preferably 90% or less, more preferably 80% or less, and even more preferably 70% or less in a plan view.

[0137] In the solid personal care product of the present invention, the line portion 20 may also be a concave portion 20B formed on the surface 10a of the base portion 10 instead of a convex portion formed on the surface 10a of the base portion 10. In other words, the line portion 20B may also be formed by a depression on the surface 10a of the base portion 10. Fig.10 shown.

[0138] When the line portion is a concave portion 20B, the depth H of the line portion 20B (see Fig.10 ) is not particularly limited, but from the viewpoint of forming a three-dimensional pattern, it is preferably 0.05 mm or more, more preferably 0.1 mm or more, and further preferably 0.12 mm or more.

[0139] Furthermore, from the viewpoint of suppressing collapse deformation of the object 70 between adjacent line portions 20B, the depth H of the line portion 20B is preferably 2 mm or less, more preferably 1 mm or less, and even more preferably 0.6 mm or less.

[0140] The depth H of the line portion 20B refers to the distance from the surface 10a of the base portion 10 to the bottom surface of the line portion 20B in the depth direction of the line portion 20 (see Fig.10 ).

[0141] The fact that the depth H of the line portion 20B is within the above range means that both the depth of the deepest portion and the depth of the shallowest portion of the line portion 20B are within the above range.

[0142] The ratio H2 / H1 of the depth H2 of the shallowest part to the depth H1 of the deepest part in the line portion 20B is not particularly limited, but is preferably 2.5% or more, more preferably 5% or more, and further preferably 8.3% or more from the perspective of easily recognizing a pattern using a subjective contour.

[0143] From the viewpoint of forming a high-definition pattern, the ratio H2 / H1 is preferably 90% or less, more preferably 80% or less, and even more preferably 70% or less.

[0144] Next, to manufacture Figure 1 to Figure 5 Taking the method of the cosmetic material 1 shown as an example, a preferred first embodiment of the method for manufacturing the solid personal care product of the present invention is described.

[0145] The manufacturing device 100 suitable for the manufacturing method of the first embodiment typically includes an extraction unit (not shown) and a line portion forming unit 50 for forming the line portion 20 on the surface 10a of the base portion 10 of the solid personal care product. The manufacturing device 100 may also include a conveying unit 80. Fig.11 shown.

[0146] The extraction unit is typically configured to extract, from the desired image, the prescribed values ​​of the pixels 45, 46, 47 corresponding to the plurality of points 25, 26, 27 on the predetermined position (hereinafter, also referred to as "path") 24 of the line portion 20. Specifically, the extraction unit can extract the prescribed values ​​of the pixels 45, 46, 47 corresponding to the plurality of points 25, 26, 27 on the path 22 of the line portion 20 from the desired image using image processing software, matrix calculation software, table calculation software, or image processing program installed in an electronic computer.

[0147] The top view shape of the passage 24 corresponds to the top view shape of the line portion 20 in the manufactured solid personal care product. Fig.12 In the specific example shown, the shape of the passage 24 in a plan view is a spiral shape.

[0148] The line portion forming section 50 typically includes: a supply section 60 for supplying a composition M having fluidity onto an object (hereinafter, also referred to as an object) 70 to which the composition is supplied; and a nozzle 61 integrally arranged in communication with the supply section 60. In the line portion forming section 50, typically, a flat object placement section 90 is arranged below and opposite to the nozzle 61, and the object 70 can be placed or fixed on the upper surface of the object placement section 90.

[0149] In the first embodiment, the object 70 is the cosmetic 1 before the line portion 20 is formed on the surface 10a of the base 10. In this embodiment, the composition M discharged from the nozzle 61 is deposited on the surface 10a of the base 10 as the object 70 to form the line portion 20.

[0150] The line portion forming unit 50 preferably includes a position adjusting unit 52 that supports or holds the supply unit 60 and the object placement unit 90 at predetermined positions. Fig.11 and Fig.13 Indicated in.

[0151] The position adjustment unit 52 preferably has a position adjustment mechanism that moves the position of the nozzle 61 and the position of the object placement unit 90 relative to each other in any direction. Thus, at least one of the nozzle 61 and the object placement unit 90 can be moved in a planar direction, a vertical direction, or a combination thereof, so that at least one of the nozzle 61 and the object 70 on the object placement unit 90 can be moved relative to the other. The position adjustment mechanism may be manual, or may be automatically controlled in response to an electrical signal sent from a controller or the like.

[0152] The supply unit 60 is a member that delivers the fluid composition M to the object 70. The supply unit 60 preferably includes a liquid delivery unit 65 and a composition storage unit 66.

[0153] The liquid supply unit 65 is preferably connected to the composition storage unit 66 via the flow path 68. Thus, the composition M supplied from the composition storage unit 66 to the inside of the liquid supply unit 65 can be continuously or discontinuously supplied to the nozzle 61 side, or the supply can be stopped.

[0154] As such a liquid feeding unit 65 , a jet-type dispenser capable of ejecting the composition M in the form of liquid droplets, or a mohno-dispenser or a spiral dispenser capable of continuously discharging the composition M can be used.

[0155] The composition storage section 66 is preferably configured such that one side thereof is connected to a pressurizing means such as air or a pump so that the composition M stored in the composition storage section 66 can be pressure-sent to the liquid sending section 65 via the flow path 68 .

[0156] Typically, the nozzle 61 is a tubular member that supplies the composition M from the supply unit 60 to the object 70. In the nozzle 61, a flow path of the composition M as a space formed inside the nozzle 61 is formed along the flow direction P of the composition M. One end of the nozzle 61, that is, the nozzle tip, constitutes a supply port for the composition M, and the other end is connected to the supply unit 60 in a communicative manner.

[0157] The constituent material of the nozzle is not particularly limited, and for example, metal, plastic, etc. can be used.

[0158] Typically, the transport unit 80 transports the object placement unit 90 to a position below the nozzle 61 and facing the nozzle 61. Specifically, the transport unit 80 includes the object placement unit 90, the stage 81, and a control device (not shown).

[0159] The manufacturing device 100 preferably has a robot 51 in the object supply / recovery section 50. The robot 51 is formed, for example, by a robot arm, and can grip the object 70. In addition, the robot 51 can release the gripping state of the object 70 on the object placement section 90, and can place the object 70 on the object placement section 90. In addition, the robot 51 can grip the object 70 on the object placement section 90 from a non-gripping state to recover it. Fig.11 Indicated in.

[0160] In the manufacturing device 100, the transport unit 80 preferably constitutes a so-called "linear transport system". Specifically, the transport unit 80 preferably has a workbench 81, an object placement unit 90 and a control device (not shown). The object placement unit 90 is typically composed of a permanent magnet. The workbench 81 is typically composed of a segment with an electromagnetic coil built in. By energizing the electromagnetic coil of the workbench 81 to generate a magnetic field, the object placement unit 90 can be suspended on the workbench 81 and rotate freely. This specific example Fig.11 shown.

[0161] The workbench 81 may be composed of a single section or a plurality of sections. When the workbench 81 is composed of a plurality of sections, each section is typically a physically independent unit and has an electromagnetic coil built in each section. The plurality of sections may be arranged continuously in one direction, but preferably the workbench 81 is configured in a two-dimensional manner in a manner connected to each other. Fig.11 In the manufacturing apparatus 100 shown, the work table 81 is composed of eight sections.

[0162] The transport unit 80 enables each workbench 81 to independently and freely transport the object placement unit 90, so the object placement unit 90 transported by each workbench 81 can also be transported to different positions below and opposite to the nozzles 61 along different transport paths. That is, different line portion forming steps can be performed on a plurality of solid personal care products as the objects 70. The line portions 20 formed in different line portion forming steps can have different patterns or the same pattern.

[0163] The manufacturing method of the present invention is a method of manufacturing a solid personal care product having a pattern based on a desired image.

[0164] The manufacturing method of the present invention preferably comprises: an extraction step of extracting the specified values ​​of corresponding pixels 45, 46, 47 from the desired image regarding multiple points 25, 26, 27 on the path 24, respectively; and a line portion forming step of forming a line portion 20 on the surface 10a of the base portion 10.

[0165] In addition, the manufacturing method of the present invention preferably includes a color tone conversion step and a target region setting step before the extraction step. The color tone conversion step may be performed after the extraction step.

[0166] Furthermore, the manufacturing method of the present invention preferably includes a conveying step of conveying the object placement unit 90 on which the object 70 is placed to a position below the nozzle 61 and facing the nozzle 61 before the line portion forming step.

[0167] In the tone conversion process, the desired image is converted into a specific tone. As a tone conversion method, for example, binarization, grayscale, and monochromaticity can be cited. Before the tone conversion process, the desired image can be processed such as gamma correction and contrast adjustment. In addition, noise removal and other processing can also be performed after the tone conversion process.

[0168] The process of setting the region of interest may be performed before or after the process of converting the tone. In the process of setting the region of interest, the portion to be formed as a pattern is set according to the desired image. For example, it is also possible to remove unnecessary portions from the desired image and retain only the portion to be formed as a pattern in the image. In addition, it is also possible to select a plurality of portions to be formed as a pattern from the desired image and reconfigure them as portions to be formed as a pattern. In addition, it is also possible to enlarge or reduce the desired image to change the image size. The enlargement and reduction processes may be performed with the aspect ratio of the image fixed or with the aspect ratio changed.

[0169] In the extraction step, the extraction unit extracts the predetermined values ​​of the pixels 45, 46, 47 corresponding to the plurality of points 25, 26, 27 on the path 24 from the desired image 40 (see Fig.12 ). Fig.12 The pixels indicated by reference numerals 45, 46, and 47 in (b) are respectively Fig.12 The pixels corresponding to the points indicated by reference numerals 25, 26, and 27 in (a) are shown. The predetermined value of the pixel can be, for example, brightness, hue, lightness, saturation, or the like.

[0170] For example, in the tone conversion process, when the desired image is binarized, the specified value of the pixel extracted in the extraction process is the brightness expressed by two grayscales of 0 and 255. In addition, in the tone conversion process, when the desired image is grayscaled, the specified value of the pixel extracted in the extraction process is the brightness expressed by 256 grayscales from 0 to 255. In addition, when obtaining the hue, the extraction process is performed after conversion to the grayscale corresponding to the color code or 2 grayscales in the tone conversion process.

[0171] The extraction process is described in detail. In the extraction process, a path image having a path matching the number of pixels of the desired image is produced. At this time, the path image is, for example, a binary image, and the brightness of the coordinates corresponding to the path is 0, and the brightness of the coordinates not corresponding to the path is 1. At the coordinate (i, j) where the brightness of any pixel P (i, j) of the path image is 0, the prescribed value of the pixel I (i, j) in the desired image corresponding thereto, such as brightness, hue, lightness, and saturation, is obtained. Pixel P is an arbitrary pixel selected from the path image. Pixel I is a pixel in the desired image, and is a pixel in the desired image corresponding to pixel P of the path image. In addition, in the case where the size of the path image is different from the size of the desired image, an image size adjustment step of adjusting the size of the path image or the size of the desired image may also be performed. The image size adjustment step may be performed before the extraction process or after the extraction process. For example, in the case where the path image is smaller than the desired image, the size may be adjusted by reducing the desired image to the size of the path image in the image size adjustment step. In addition, when the path image is larger than the desired image, the desired image may be enlarged to the size of the path image in the image resizing step to adjust the size. In the image resizing step, the desired image size is typically adjusted to match the size of the path image, but the path image may be enlarged or reduced to match the size of the desired image.

[0172] exist Fig.12 In the figure, for the sake of convenience, three points 25, 26, 27 on the path 24 and three pixels 45, 46, 47 corresponding to the points 25, 26, 27 are shown, but the number of the points and the number of the pixels are not particularly limited.

[0173] In addition, regarding a point on the path 24, the pixel corresponding to the point may be only one or more. For example, a point on the planned formation position 22 of the line portion 20 may be a region including a plurality of pixels in the desired image. In this case, the average value of the prescribed values ​​of the plurality of pixels can be used as the prescribed value of the point at the planned formation position 22 of the line portion 20. The average value may be a value rounded to the first decimal point.

[0174] In the extraction process, instead of creating a path image having a path matching the number of pixels of the desired image and obtaining the specified value of the pixel I (i, j) in the desired image, the image having the path can be programmed (for example, G-coded) and the specified value of the pixel I (i, j) in the desired image corresponding to the coordinates (i, j) in the program can be obtained.

[0175] In the conveying process, the object placement unit 90 on which the object 70 is placed is conveyed to a position below the nozzle 61 and opposite to the nozzle 61. Specifically, it is preferred that the electromagnetic coil of the workbench 81 is energized to generate a magnetic field so that the object placement unit 90 is suspended. Then, the object 70 is preferably placed on the object placement unit 90 using the robot 51. The position of the object placement unit 90 is preferably controlled by a control device (not shown) of the conveying unit 80. Specifically, it is preferred that the object placement unit 90 is conveyed to a position below the nozzle 61 and opposite to the nozzle 61.

[0176] In the line portion forming step, the line portion 20 is formed on the surface 10a of the base portion 10. Specifically, it is preferred that the composition M constituting the line portion 20 is discharged and deposited on the object 70 placed on the object placement portion 90 transported in the transport step, thereby forming the line portion 20. At this time, it is preferred that the composition M is supplied from the nozzle 61 to the object 70 (see Fig.13 (a)), while moving at least one of the nozzle 61 and the object 70 relative to the other (refer to Fig.13 (b)), a deposited body made of the composition, that is, the line portion 20 is formed on the object 70. In the line portion forming step, the composition M having fluidity is preferably discharged from the nozzle 61.

[0177] When at least one of the nozzle 61 and the object 70 is moved relative to the other, the relative position of the nozzle 61 relative to the object 70 is preferably moved along the path 24. In the first embodiment, at least one of the nozzle 61 and the object 70 is preferably moved relative to the other so that the line portion 20 is arranged in a spiral shape when viewed from above.

[0178] The relative movement direction of the nozzle 61 can be moved in a planar direction, a vertical direction, or a combination thereof, depending on the planar shape, three-dimensional shape, or drawn pattern of the target line portion 20 .

[0179] The pattern in this specification refers to various characters such as Japanese characters such as hiragana and katakana, letters, Arabic numerals, Roman numerals, foreign characters, straight lines and curves, and figures composed of their combinations, geometric shapes, symbols, colors, patterns, or shapes of their combinations.

[0180] Typically, the pattern is formed by the line portion 20, by forming a spiral or other graphic or geometric pattern in the narrow portion 20b, and based on the pattern of the wide portion 20a or a pattern using a subjective contour, a graphic, geometric shape, symbol, color, pattern or a combination thereof is formed consisting of various characters, straight lines and curves and their combinations.

[0181] These patterns are preferably expressed by coloring with a color that is the same as or different from the original base color of the object 70 on which the patterns are arranged.

[0182] Preferably, in the line portion forming step, an occupied area S1 corresponding to the specified value is given according to the specified value of the pixel extracted in the extraction step, thereby changing the above-mentioned occupied area ratio S1 / S0. For example, when the composition M is supplied from the nozzle 61 to the object 70, one or more of the relative moving speed V of the nozzle 61 with respect to the base 10, the distance F between the base 10 and the nozzle 61, and the supply speed Q of the composition M supplied from the nozzle 61 to the surface 10a of the base 10 is changed according to the specified value of the pixel extracted in the extraction step, thereby giving the occupied area S1 corresponding to the above-mentioned specified value. By changing one or more of the relative moving speed V, the distance F, and the supply speed Q, the width W of the line portion 20 formed on the object 70 is changed, and the occupied area S1 can be made to correspond to the specified value. In addition, instead of changing the width W of the line portion 20 formed on the object 70, the height T of the line portion 20 may be changed, or both the width W and the height T of the line portion 20 may be changed.

[0183] The following description will be made by taking the case where the relative moving speed V is changed as an example. For example, when the desired image is binarized in the tone conversion process, the specified value is represented by two grayscale levels of 0 and 255, and the relative moving speed V can be controlled in two stages of low speed and high speed according to the specified value. The relative moving speed V can be set to low speed when the specified value is 0, and to high speed when the specified value is 1, or vice versa. When the relative moving speed V is low speed, the portion corresponding to the wide width portion 20a of the line portion 20 is formed, and when the relative moving speed V is high speed, the portion corresponding to the narrow width portion 20b of the line portion 20 is formed.

[0184] When the desired image is grayed in the tone conversion process, the above-mentioned prescribed value is represented by 256 grayscale levels of 0 to 255. For example, the prescribed value can be divided into three stages of 0 to 100, 101 to 200, and 201 to 255. When the prescribed value is 0 to 100, the relative moving speed V is set to a low speed, when the prescribed value is 101 to 200, the relative moving speed V is set to a medium speed, and when the prescribed value is 201 to 255, the relative moving speed V is set to a high speed. In addition, there is no particular restriction on how many stages the above-mentioned prescribed value is divided into. The above-mentioned prescribed value can be divided into two stages, or it can be divided into 256 stages. In addition, there is no particular restriction on the threshold value when the above-mentioned prescribed value is divided into multiple stages.

[0185] In addition, the speed may be determined by limiting the grayscale level of a 256-grayscale image to 2 grayscale levels, 4 grayscale levels, 8 grayscale levels, 16 grayscale levels, etc., according to the grayscale conversion method of the image. For example, when the image is converted to 2 grayscale levels, the relative moving speed V may be set to a low speed when the specified value is 0 to 127, and the relative moving speed V may be set to a high speed when the specified value is 128 to 255. Based on the same consideration, when the image is converted to 4 grayscale levels, the specified value may be divided into 0 to 63, 64 to 127, 128 to 191, 192 to 255, so that the speed changes in 4 stages from low to slow. The same is true for 8 grayscale levels, 16 grayscale levels, etc.

[0186] When the distance F or the supply speed Q is changed, the same as when the relative moving speed V is changed may be used.

[0187] The relative moving speed V, the distance F, or the supply speed Q may be changed continuously or in stages.

[0188] Finally, the supply of the composition M from the nozzle 61 is stopped (see Fig.13 (c)). Through the above steps, the line portion 20 having a predetermined shape is formed on the object 70.

[0189] Thus, for example, the line portion 20 formed using the cosmetic slurry can be made into a three-dimensional object composed of the line portion containing the cosmetic derived from the composition.

[0190] The nozzle 61 may be relatively moved on the same plane as the object 70 or relatively separated therefrom as required.

[0191] In this way, the solid personal care product of the present invention is manufactured by forming the line portion 20 on the surface 10a of the base portion 10. In addition, the solid personal care product manufactured in this way can be directly used as a target personal care product, or can be further processed to become a target personal care product. In either case, according to the manufacturing method of the present invention, a mold frame or the like is not required, and the desired design can be drawn with high precision and high fineness by the formula of the composition itself, so that the shape and size can be easily and efficiently molded and decorated with good precision.

[0192] In the line portion forming process, an occupied area S1 corresponding to the specified value of the pixel extracted in the extraction process is assigned, thereby changing the ratio S1 / S0 of the above-mentioned occupied area. Therefore, the line portion 20 can be efficiently manufactured, which produces a pattern utilizing a subjective contour, and the cosmetic material 1 having a three-dimensional pattern that can express light and dark can be efficiently manufactured.

[0193] The relative moving speed V is not particularly limited, but is preferably 1 mm / min or more, more preferably 2 mm / min or more, and even more preferably 3 mm / min or more from the viewpoint of improving productivity.

[0194] The relative moving speed V is not particularly limited as long as it can be supplied, but from a practical point of view, it is preferably 5000 mm / min or less, more preferably 500 mm / min or less, and further preferably 200 mm / min or less.

[0195] When the line width is changed, the relative moving speed V is preferably greater than 10 mm / min, more preferably greater than 50 mm / min, further preferably greater than 300 mm / min, and is preferably less than 60,000 mm / min, more preferably less than 10,000 mm / min, further preferably less than 3,000 mm / min.

[0196] The relative movement speed V can be appropriately changed by, for example, changing the driving speed of the above-mentioned position adjustment unit 52. In addition, the relative movement speed V can be appropriately changed by changing the conveying speed of the object placement unit 90 on which the object 70 is placed.

[0197] In addition, the relative movement speed V in this specification is expressed as an absolute value.

[0198] The distance F is not particularly limited, but is preferably 0.05 mm or more, more preferably 0.1 mm or more, and even more preferably 0.15 mm or more from the viewpoint of suppressing contact between the nozzle 61 and the object 70 .

[0199] From the viewpoint of improving the followability of the discharged composition M to the relative movement of the nozzle 61 and the object 70 , the distance F is preferably 5 mm or less, more preferably 2.5 mm or less, and even more preferably 2 mm or less.

[0200] The feed speed Q is not particularly limited, but is preferably 0.05 mm / s from the viewpoint of improving production capacity. 3 / s or more, more preferably 0.1 mm 3 / s or more, more preferably 0.4 mm 3 / s or more.

[0201] The supply speed Q is not particularly limited as long as it can be operated, but is preferably 150 mm / s from the viewpoint of stably forming a high-definition line portion by balancing the relative movement speed of the nozzle 61. 3 / s or less, more preferably 50mm 3 / s or less, more preferably 15mm 3 / s or less.

[0202] The supply rate Q can be appropriately changed by, for example, appropriately adjusting the rotation speed of the rotor, or adjusting the shape, inner diameter, viscosity of the composition M, etc. of the nozzle 61 when the above-mentioned dispenser is used as the liquid delivery unit 65 in the supply unit 60 .

[0203] In the line portion forming step, the line portion 20 is preferably formed by discharging the composition M constituting the line portion 20 from the nozzle 61 onto the surface 10a of the base portion 10 and depositing the composition M. This allows the line portion 20 to be easily formed.

[0204] Hereinafter, a second embodiment of the production method of the present invention will be described.

[0205] The manufacturing method of the second embodiment will be described mainly with respect to the differences from the manufacturing method of the first embodiment. The description of the first embodiment described above is applied appropriately to any point not particularly described.

[0206] In the manufacturing method of the present invention, in the line portion forming step, instead of discharging and depositing the composition M from the nozzle 61 onto the surface 10a of the base 10, the line portion 20B may be formed by scraping off a portion of the surface 10a of the base 10. In this manufacturing method, the formed line portion 20B is a concave portion.

[0207] The line portion forming unit 50B of the manufacturing apparatus 100 preferably applied to the manufacturing method of the second embodiment includes a cutting tool 33 and a position adjusting unit 34 that supports or holds the cutting tool 33 at a predetermined position. Fig.14 An example of the line portion forming portion 50B is shown.

[0208] The position adjustment unit 34 preferably has a position adjustment mechanism that moves the position of the cutting tool 33 relatively in any direction. Thus, at least one of the cutting tool 33 and the object placement unit 90 can be moved in a planar direction, a vertical direction, or a combination thereof, so that at least one of the cutting tool 33 and the object 70 on the object placement unit 90 can be moved relative to the other. The position adjustment mechanism may be manual, or may be automatically controlled in response to an electrical signal sent from a controller or the like.

[0209] The cutting tool 33 typically has an expanded diameter portion 33a in which at least a portion of the front end of the cutting tool 33 gradually expands in diameter upward in the vertical direction Z. The expanded diameter portion 33a may be continuously expanded (see Fig.14 ), and the diameter may be expanded in stages. Examples of the cutting tool 33 include an end mill, a drill, and a milling cutter.

[0210] The line portion forming portion 50B may also include a removing portion (not shown) for removing a portion of the surface 10a of the base portion 10 to be cut off. Examples of the removing portion include an air supply device for scattering the cut off portion by air supply, and a suction device for sucking the cut off portion.

[0211] In the line portion forming step of the second embodiment, the line portion 20B is formed by changing the relative position of the cutting tool 33 with respect to the base portion 10 in the plane direction while a part of the cutting tool 33 is inserted into the base portion 10. When the relative position is changed, at least one of the cutting tool 33 and the object 70 is moved relative to the other so that the relative position moves along the path 24.

[0212] In the second embodiment, the line portion 20B is formed while changing the insertion depth K of the expanded diameter portion in accordance with a predetermined value of the pixel extracted in the extraction step.

[0213] For example, when the desired image is binarized in the tone conversion process, the predetermined value is represented by two grayscale levels of 0 and 255, and the depth K can be controlled in two stages according to the predetermined value. The depth K can be shallow when the predetermined value is 0, and can be deep when the predetermined value is 1, or vice versa. When the depth K is shallow, the width W of the line portion 20B is relatively narrow, and when the depth K is deep, the width W of the line portion 20B is relatively wide. When the depth K is shallow, a portion of the line portion 20B corresponding to the narrow width portion 20b is formed. When the depth K is deep, a portion of the line portion 20B corresponding to the wide width portion 20a is formed.

[0214] When the desired image is grayed in the tone conversion process, the above-mentioned prescribed value is represented by 256 grayscale levels of 0 to 255. For example, the prescribed value can be divided into three stages of 0 to 100, 101 to 200, and 201 to 255, and the above-mentioned depth K can be controlled into three stages according to the prescribed value. For example, when the prescribed value is 0 to 100, the above-mentioned depth K can be made shallowest, and when the prescribed value is 201 to 255, the above-mentioned depth K can be made deepest, and when the prescribed value is 101 to 200, the depth can be formed to be between the above-mentioned depth K when the prescribed value is 0 to 100 and the above-mentioned depth K when the prescribed value is 201 to 255. In addition, there is no particular restriction on how many stages the above-mentioned prescribed value is divided into. The above-mentioned prescribed value can be divided into two stages, or it can be divided into 256 stages. In addition, there is no particular restriction on the threshold value when the above-mentioned prescribed value is divided into multiple stages.

[0215] In addition, the speed may be determined by limiting the image with 256 gray levels to gray levels such as 2 gray levels, 4 gray levels, 8 gray levels, 16 gray levels, etc. according to the gray level conversion method of the image. For example, when converting an image with 2 gray levels, the relative moving speed V may be set to a low speed when the specified value is 0 to 127, and the relative moving speed V may be set to a high speed when the specified value is 128 to 255. When converting an image with 4 gray levels according to the same consideration, the specified value may be divided into 0 to 63, 64 to 127, 128 to 191, 192 to 255, so that the speed changes in 4 stages from low to slow. The same is true for 8 gray levels, 16 gray levels, etc.

[0216] The depth K may be changed continuously or in stages.

[0217] According to the manufacturing method of the second embodiment, similarly to the manufacturing method of the first embodiment, the line portion 20 that produces a pattern using a subjective outline can be efficiently manufactured, and the cosmetic material 1 having a three-dimensional pattern that can express light and dark can be efficiently manufactured. In addition, according to the manufacturing method of the second embodiment, the line portion 20B as a concave portion can be easily formed.

[0218] The depth K in the vertical direction is not particularly limited, but is preferably 0.05 mm or more, more preferably 0.1 mm or more, and further preferably 0.15 mm or more from the viewpoint of forming a three-dimensional pattern.

[0219] Furthermore, from the viewpoint of suppressing deformation of the object 70 between adjacent line portions 20B, the depth K in the vertical direction is preferably 1 mm or less, more preferably 0.5 mm or less, and even more preferably 0.3 mm or less.

[0220] The solid personal care products of the present invention include products that can be applied to the human body by applying them to the skin, or applying, spreading or dripping a liquid dissolved or dispersed in a solvent such as water on the skin, etc. The application can be done using an application tool such as a puff or a brush, or directly without using an application tool.

[0226] The composition M may be composed of a single component or may be composed of a plurality of components.

[0227] From the viewpoint of improving the uniform dispersibility of the materials contained in the composition M and stabilizing the quality, and suppressing the deformation of the deposit discharged from the nozzle, i.e., the line portion 20 and stabilizing the shape, the viscosity of the composition M is preferably 0.1 Pa·s or more, more preferably 0.5 Pa·s or more, and further preferably 1 Pa·s or more.

[0229] The viscosity of the above-mentioned composition M is measured on the basis of setting the temperature of the composition M to the same temperature as the composition M when it is supplied from the nozzle, that is, the temperature when discharged. For example, when the composition M is a substance other than a heated molten liquid such as a slurry, and is supplied from the nozzle at room temperature (25°C), it is a value measured at 25°C using a B-type viscometer (manufactured by Toki Sangyo Co., Ltd., digital viscometer TVB-10R). The measurement conditions at this time are to set the rotor to any one of rotor No. M1, M2, M3, M4, H1, H2, H3, H4, H5, H6 and H7 to match the viscosity range of the sample, set the rotation speed to 0.5 rpm to 100 rpm, and use the automatic stop function for the measurement time. In the case where the composition M is a heated molten liquid, the viscosity is measured under the above-mentioned measurement conditions on the basis of setting the temperature of the composition M to the same temperature as the composition when it is supplied from the nozzle 61.

[0230] The composition M preferably contains one or two or more selected from solids such as powders and oils.

[0275] As mentioned above, although this invention was demonstrated based on embodiment and implementation mode of this invention, this invention is not limited to the said embodiment and implementation mode, It can change suitably.

[0276] For example, in Figure 1 In the cosmetic material 1 shown in the figure, the top view shape of the line portion 20 is a circular spiral shape, but instead of this structure, it can also be a quadrilateral spiral shape (see Fig.15 (a)), triangular vortex (refer to Fig.15 (b) etc. In addition, Fig.15 In (a) and (b), for the sake of convenience, the illustration of the sparse and dense structure of the line portion 20 is omitted.

[0277] In addition, Figure 1 In the illustrated cosmetic material 1, the surface 10a of the base portion 10 is a flat surface, but instead of this structure, it may be a curved surface.

[0278] In addition, for example, Fig.14 In the line portion forming part 50B shown, the line portion 20B as a concave portion is formed by the cutting tool 33, but instead of this structure, a stacking molding machine, a so-called 3D printer, can be used to form a solid personal care product having the line portion 20B as a concave portion. In addition, the line portion 20 as a convex portion can also be formed by a stacking molding machine. The line portion 20 can be directly formed on the surface 10a of the base portion 10 using the stacking molding machine, or the line portion 20 formed by the stacking molding machine can be arranged on the surface 10a of the base portion 10. In addition, the solid personal care product having the line portion 20 as a convex portion can also be formed by a stacking molding machine.

[0279] Alternatively, the stripe portion 20 may be formed by press-molding the object 70. In this case, the stripe portion 20 is formed using a press mold in which a pattern corresponding to the stripe portion 20 is applied to a mold for press molding.
