Description

  The present invention relates to a method for producing a multicolor solid cosmetic material in which a color boundary is not partitioned by a frame of a decorative dish.

  Conventionally, various manufacturing methods have been proposed for multicolor solid cosmetics in which color boundaries are not partitioned by a frame of a decorative dish. For example, Patent Document 1 discloses a technique in which blocks of each color (preliminary mold product) constituting a multicolor solid cosmetic are individually created, and after these are set one by one on a decorative dish, the whole is pressed. Has been. In Patent Document 2, there is a method in which a penetrating part for passing a partition is provided in a decorative dish, the partition is inserted into the penetrating part and filled with cosmetics, and then the partition is removed to shrink the decorative dish and close the penetrating part.

  However, in the method of Patent Document 1 described above, it is necessary to individually create a pre-molded block for each color and set them one by one on a decorative dish. Therefore, the number of steps increases as the number of colors increases. Another problem is that it is difficult to set complicated patterns. Moreover, in the methods of Patent Documents 2 and 4, since it is necessary to provide a through-hole for allowing the partition plate to pass through in the dressing plate, the strength of the dressing plate is likely to be insufficient. The problem of insufficient strength becomes more prominent as the pattern becomes more complicated. Furthermore, the method of Patent Document 3 has a disadvantage that the packing is easily attached and it is difficult to remove the partition plate.

  This invention is made | formed in view of this situation, The objective is to manufacture the multicolor solid cosmetics with a clear color boundary easily and cheaply, without providing a partition in a decorative dish.

  In order to solve such a problem, the present invention provides a first step of preparing a cosmetic filling body in which a plurality of colors of cosmetics are filled in each of a plurality of filling spaces separated from each other by a frame, and a plurality of fillings The frame body enters the recess by relatively displacing the frame body with respect to the extrusion mold having a plurality of extrusion surfaces having surface shapes corresponding to the respective opening shapes of the spaces and the recesses into which the frame body can be inserted. However, a second step of extruding a plurality of colors of cosmetics on a plurality of extrusion surfaces at the same time and accommodating the extruded plurality of colors of cosmetics in a cosmetic dish, and a plurality of colors of cosmetics accommodated in the cosmetic dish A method for producing a multi-color solid cosmetic comprising the third step of molding the mold.

  Here, in the present invention, in the case where the cosmetic filler is formed using the cosmetic powder as the main material of the dry solid cosmetic, the first step is the first opening on the lower opening side of the frame. A step of closing with a closing member, and a cosmetic powder as a main material of a dry solid cosmetic, or a main material of a wet solid cosmetic, in each of a plurality of filling spaces from the opened upper opening side of the frame body Filling the slurry, and the upper opening side of the frame body was closed with the second closing member, and then the plurality of filling spaces were filled by relative displacement between the first closing member and the second closing member. A step of pressing the filling material in a lump so that the multi-color cosmetic is compressed. Alternatively, the first step includes the step of closing the lower opening side of the frame body with the first closing member and closing the upper opening side of the frame body with the second closing member; From a plurality of filling ports provided in one of the closing member and the second closing member, each of the plurality of filling spaces is filled with slurry as a main material of the wet solid cosmetic at a predetermined filling pressure. The step of bringing the plurality of color cosmetics into a compressed state may be included. Further, in the above case, the extrusion mold may be used as one of the first closing member and the second closing member.

  According to the present invention, the plurality of colors of cosmetics filled in the frame body are extruded using an extrusion die, and the accommodation in these decorative dishes is performed at once. At that time, since each cosmetic is extruded along the frame, a clear color boundary can be easily obtained without providing a partition on the decorative dish. In addition, since it is not necessary to set the pre-molded blocks individually on the decorative dish, the multicolor solid cosmetic can be manufactured at low cost.

  FIG. 1 is an external perspective view of the multicolor solid cosmetic according to the present embodiment. The multicolor solid cosmetic 1 is typically a foundation, a face powder, an eye shadow or the like, and may be either a dry solid cosmetic or a wet solid cosmetic. The dry-type solid cosmetic is obtained by stamping and solidifying a main material, that is, a cosmetic powder as a main material. In addition, the wet solid cosmetics are solidified by absorbing and drying volatile components in the slurry (cosmetic fluid) as the main material. The slurry is a mixture of a cosmetic base material and a volatile solvent such as ethanol, water, liquid paraffin, isoparaffin, isopropyl alcohol. The wet solid cosmetic has a characteristic that a moist feeling of use can be obtained due to the sparse particle density as compared with the dry solid cosmetic.

  The multi-color solid cosmetic 1 is composed of a plurality of colors of cosmetics accommodated in a substantially rectangular decorative dish 2, and a clear color boundary is formed on the surface thereof. In this specification, the terms “different colors” or “plural colors” are used in a sense that it is sufficient if the user can visually recognize the difference. Therefore, in addition to differences in lightness, saturation, and hue, even if the same color is used, those with different textures, such as those with pearls added and those with no pearls, fall under the category of “different colors” here. include. The illustrated color pattern is a curved stripe pattern, but the present invention is not limited to this, and can be defined by a frame 3 to be described later, including a linear stripe pattern and a lattice pattern. As long as it is any pattern.

  FIG. 2 is an external perspective view of the frame 3 used for producing the multicolor solid cosmetic 1 shown in FIG. The frame 3 has a base 3a, an outer frame 3b, and an inner frame 3c. An opening that penetrates up and down is provided substantially at the center of the base 3a. The inner surface of the opening is flush with the inner surface of the outer frame 3b that protrudes downward from the lower surface of the base 3a. The frame shape of the outer frame 3b corresponds to the opening shape of the vanity plate 2, and in the present embodiment, has a substantially rectangular frame shape. A plurality of inner frames 3c are connected to the inside of the outer frame 3b. Each inner frame 3c defines the color boundary of the multicolor solid cosmetic 1 described above, and there are as many as the number of color boundaries. Then, each of the plurality of filling spaces separated from each other by the frame body 3 is filled with a plurality of color cosmetics constituting the multicolor solid cosmetic 1 in a compressed state.

  Hereinafter, the manufacturing method of the multicolor solid cosmetic 1 according to the present embodiment will be described in detail with reference to FIGS. 3 to 9. 3 to 9 show the AA cross section shown in FIG. 1 and FIG. 2, respectively. First, a cosmetic filling body 8 (see FIG. 7) in which cosmetics of each color are compressed and filled in each filling space in the frame 3 shown in FIG. 2 is prepared. The cosmetic filler 8 is a set of the frame 3 and a filler in the frame 3. The filler is a cosmetic powder that is a main material of the dry solid cosmetic, and a wet type. You may form with either of the slurry used as the main material of solid cosmetics.

  FIG. 3 and FIG. 4 are explanatory diagrams of a process for forming a cosmetic filler 8 made of a dry solid cosmetic. First, as shown in FIG. 3, the lower opening side of the frame 3 is closed with a closing member 4. On the upper surface of the closing member 4, a recess 4a into which the inner frame 3c of the frame 3 can be inserted is provided corresponding to the position of the inner frame 3c. Next, a predetermined amount of cosmetic powder of each color is filled into each of the filling spaces partitioned by the frame 3 from the upper opening side (open state) of the frame 3. Thereafter, as shown in FIG. 4, the upper opening side of the frame 3 is closed with a closing member 5. On the lower surface of the closing member 5, a recess 5a into which the inner frame 3c of the frame 3 can be inserted is provided corresponding to the position of the inner frame 3c. Then, the lower closing member 4 is raised while the upper closing member 5 is fixed in position. Thereby, the upper and lower closing members 4 and 5 are relatively displaced while the tip of the inner frame 3c enters the recess 4a of the closing member 4, and the fillings in the plurality of filling spaces are pressed together. By passing through the above processes, the cosmetic filling body 8 in which cosmetics of a plurality of colors are filled and solidified inside the frame 3 is obtained.

  Note that the processes illustrated in FIGS. 3 and 4 can be applied as they are even when a slurry is used instead of the cosmetic powder. Alternatively, the filling material may be pressed by lowering the upper closing member 5 while the lower closing member 4 is fixed in position. Further, regarding the closing members 4 and 5 which are fixed in position during pressing, the concave portions 4a and 5a into which the inner frame 3c is inserted are not necessary, and a simple plate-like member may be used.

  FIG. 5 and FIG. 6 are explanatory diagrams of a process for forming a cosmetic filling body 8 made of a wet solid cosmetic (back filling). First, as shown in FIG. 5, the lower opening side of the frame 3 is closed with the closing member 4, and the upper opening side of the frame 3 is closed with the closing member 5. The lower closing member 4 is a plate-like member, and a plurality of filling ports 4b for filling the slurry are provided corresponding to the positions of the respective filling spaces. Moreover, the recessed part 5a which can insert the inner frame 3c in the frame 3 is provided in the lower surface of the upper closure member 5 corresponding to the position of the inner frame 3c. Next, as shown in FIG. 6, slurry is filled into each of the plurality of filling spaces from the plurality of filling ports 4b with a predetermined filling pressure. As a result, the slurry filled in the filling space is pressurized at a filling pressure, whereby a cosmetic filling body 8 in which a plurality of colors of cosmetics are filled and solidified inside the frame 3 is obtained. In this filling step, the volatile solvent that has oozed out of the slurry by pressurization may be sucked and removed through a fine suction hole (not shown) provided in the upper closing member 5. In addition, when it is desired to compress the filler at a filling pressure or higher, after the above steps, the upper closing member 5 is lowered while the lower closing member 4 is fixed in position, and the filling is pressed. Also good.

  In addition, although the process illustrated in FIG. 5 and FIG. 6 has described the back filling in which the slurry is filled from below, front filling in which the slurry is filled from above may be used. In this case, a plurality of filling ports are provided in the upper closing member 5, and the slurry is filled from them with a predetermined filling pressure.

  Next, as shown in FIG. 7, the cosmetic filling body 8 as a pre-molded product that has undergone the above-described steps is accommodated in the cosmetic dish 2, and the extrusion mold 6 is set on the upper opening side of the cosmetic filling body 8. . The extrusion die 6 has a recess 6a into which the frame body 3 can be inserted, and a plurality of extrusion surfaces 6b having surface shapes corresponding to the respective opening shapes of the plurality of filling spaces. And each extrusion surface 6b is inserted in the upper opening of the filling space corresponding to self.

  Next, as shown in FIG. 8, the frame body 3 is raised and the frame body 3 is relatively displaced with respect to the upper extrusion die 6. As a result, while the upper end of the frame 3 enters the recess 6a, the cosmetics of a plurality of colors are pushed out along the frame 3 by pressing from the plurality of extrusion surfaces 6b. The extruded multi-color cosmetics are accommodated in the decorative tray 2. In this accommodated state, there is a gap corresponding to the width of the inner frame 3c between the adjacent cosmetics, and a gap corresponding to the width of the outer frame 3b between the inner part of the decorative dish 2 and the cosmetics. Exists.

  Finally, as shown in FIG. 9, after removing the frame 3 and the extrusion die 6, the press head 7 is used to mold a plurality of color cosmetics contained in the dressing plate 2 in a lump (finishing press). ). Thereby, the said clearance gap produced when removing the frame 3 is eliminated, and the multicolor solid cosmetic 1 of the dense state shown in FIG. 1 is completed.

  Thus, according to this embodiment, by using the extrusion die 6 and extruding a plurality of colors of cosmetics filled in the frame body 3, the accommodation in these decorative dishes 2 is performed in a lump. At that time, since each cosmetic is extruded along the frame 3, a clear color boundary can be easily obtained without providing a partition in the decorative dish 2. In addition, since it is not necessary to set the preliminarily molded blocks individually on the decorative dish 2, the multicolor solid cosmetic 1 can be manufactured at low cost.

  In the above-described embodiment, the closing members 4 and 5 and the extrusion die 6 are used as separate members, but one of the closing members 4 and 5 may be shared with the extrusion die 6.

  Moreover, in embodiment mentioned above, as shown in FIG. 7, the example which extrudes in the state in which the frame 3 was accommodated in the inside of the vanity plate 2 was demonstrated. In this case, it is necessary to make the shape of the outer peripheral surface of the outer frame 3 b correspond to the opening shape of the dressing plate 2 in order to accommodate the frame 3 in the dressing plate 2. However, the present invention is not limited to this, and may be performed without housing the frame 3 in the interior of the decorative dish 2. For example, the outer frame 3b is pushed out while being in contact with the upper edge of the decorative plate 2. In this case, the shape of the inner peripheral surface of the outer frame 3b may be made to correspond to the opening shape of the decorative dish 2. In this way, the generation of the gap due to the outer frame 3b can be prevented in advance.

  The method for producing a multicolor solid cosmetic according to the present invention can be widely applied to various solid cosmetics such as foundations, face powders, and eye shadows regardless of whether they are dry or wet.
