Slurry pushed out from a uniaxial eccentric screw pump 5 is discharged from the filling hole 1d without being separated by the side part of the cosmetic tray 2. Thus, the inside of the filling space 1a is filled with the slurry.

Description

  The present invention relates to a wet cosmetic manufacturing method and a filling device, and more particularly, to side filling of a slurry.

  In Patent Document 1, a slurry, that is, a cosmetic base material, ethanol, water, liquid paraffin, isoparaffin, Side filling is disclosed in which a fluid mixed with a volatile solvent such as isopropyl alcohol is filled. Specifically, first, the upper and lower openings provided in the forming frame are closed with a pair of hollow sandwiching bodies through a permeable membrane material. Thereby, a filling space is formed inside the forming frame. Next, the slurry is filled into the filling space by discharging the slurry from a filling hole provided on the side of the forming frame. At that time, the volatile solvent contained in the slurry is sucked by the hollow sandwiching body through the permeable membrane material, whereby the volatile solvent in the slurry is removed. Then, the solidified slurry in the filling space, that is, the punched product is taken out from the molding frame. After that, the molded product is cut into a desired shape and size, transferred to a decorative dish, and finish-pressed to complete the final product.

Japanese Patent Publication No. 6-69934

  However, in the method of Patent Document 1 described above, it is necessary to transfer the punched material generated by the side filling to the decorative dish. Moreover, although the die-cut before finishing press depends on the prescription, in many cases, it has a characteristic that it is brittle and easily collapsed because it is loosely pressurized. Therefore, when transferring to a decorative dish, there exists a possibility that a casting may collapse | crumble, and the fall of a yield is caused.

  Therefore, an object of the present invention is to eliminate the need for transfer work to a decorative dish by performing side filling directly on the decorative dish.

  In order to solve this problem, the first invention provides a method for producing a wet cosmetic. The method includes a first step of accommodating the decorative dish below a filling space formed higher than the upper edge of the decorative dish, a second step of covering the opening above the filling space with a covering surface, And a third step of filling the slurry into the filling space by discharging the slurry from a filling hole provided at a position higher than the upper edge of the decorative dish on the side of the space.

  Here, in the first invention, the third step removes the volatile solvent in the slurry by sucking the volatile solvent contained in the slurry through the suction holes provided in the coating surface. It is preferable to have a step. Moreover, you may further have the 4th step which slides the slurry with which it filled in the filling space by the flat coating | coated surface by relative movement of a coating | coated surface and a filling space.

  2nd invention provides the filling apparatus for wet cosmetics. This device has a frame body having a filling space formed higher than the upper edge of the decorative dish, a covering surface covering the opening above the filling space, and an upper edge of the decorative dish on the side of the filling space. It is provided at a high position and has a filling hole for filling the slurry in the filling space.

  In 2nd invention, in order to remove a volatile solvent by attracting | sucking the volatile solvent contained in a slurry, it is preferable to further have the suction hole provided in the coating surface.

  According to the 1st or 2nd invention, the operation | work which transfers a stamping thing to a decorative dish becomes unnecessary by carrying out the side filling of the slurry in the filling space containing a decorative dish. In addition, since this work is no longer necessary, it is possible to eliminate the problem of collapse of the punched article, which contributes to an improvement in yield. Furthermore, the working efficiency can be improved by making the position of the filling hole on the side of the filling space higher than the upper edge of the decorative dish. When the position of the filling hole is lower than the upper edge of the vanity plate, a through hole that connects the filling hole and the filling space must be provided in the vanity plate. This is necessary separately, but according to the present invention, this is not necessary.

  The wet cosmetics to be manufactured in the present embodiment are solidified by absorbing and drying the volatile solvent in the slurry among powder solid makeup cosmetics such as foundation, face powder, and eye shadow. The slurry is a fluid obtained by mixing a cosmetic base material with a volatile solvent such as ethanol, water, liquid paraffin, isoparaffin, isopropyl alcohol. Wet cosmetics have the characteristics of a smooth touch, excellent sensory characteristics such as fit, and excellent impact resistance as compared with dry cosmetics in which powder cosmetics are directly cast.

  First, as shown in FIG. 1, the dressing plate 2 is accommodated inside the frame body 1. A filling space 1a having an opening exposed in the flat surface 1c on the upper portion of the frame 1 is provided at the approximate center of the frame 1, and the dressing plate 2 is accommodated in the filling space 1a. The lower portion of the filling space 1a has an inner diameter that substantially matches the outer diameter of the dressing plate 2 so as to accommodate the dressing plate 2 without a gap. On the other hand, a stepped portion 1b protruding in a stepped shape toward the inside is formed on the entire upper portion of the filling space 1a. The opening diameter including the stepped portion 1b is substantially the same as the inner diameter of the dressing plate 2, so that the inner surfaces of both the stepped portion 1b and the dressing plate 2 are substantially flush when the dressing plate 2 is accommodated. The dressing plate 2 is housed by placing the dressing plate 2 so as to be directly below the filling space 1 a and covering the frame 1 from above the dressing plate 2.

  A filling hole 1d penetrating the frame body 1 in the horizontal direction is provided in an inner peripheral portion of the filling space 1a higher than the upper edge of the dressing plate 2, that is, the step portion 1b in the present embodiment. The slurry is filled by side filling through the filling hole 1d. The filling hole 1 d is formed at a position higher than the housing part of the decorative dish 2. Therefore, the filling hole 1d communicates with the filling space 1a without being blocked by the side surface of the decorative dish 2 even when the decorative dish 2 is accommodated in the filling space 1a. The diameter of the filling hole 1d is appropriately set according to the formulation of the slurry to be filled, and the target filling pressure, filling speed, and the like are also taken into consideration. The vertical width (height) of the stepped portion 1b needs to be at least larger than the diameter of the filling hole 1d exposed to the side of the stepped portion 1b. It is set after taking into account the increase in height in anticipation of a decrease.

  Next, as shown in FIG. 2, the slurry is side-filled in the filling space 1 a including the decorative dish 2. Specifically, first, the suction head 3 disposed immediately above the filling space 1a is lowered, and the opening of the filling space 1a exposed from the flat surface 1c is covered with the absorbent sheet 4 with the covering surface of the suction head 3 interposed therebetween. Block with (bottom). The absorbent sheet 4 is used to absorb a volatile solvent contained in the slurry, and paper or nonwoven fabric having high absorbability can be used. Then, the uniaxial eccentric screw pump 5 is driven in a state where the filling space 1 a is blocked by the coating surface of the suction head 3, and a certain amount of slurry is pushed out to the supply pipe 6. Slurry having a predetermined fluidity is discharged and filled into the filling space 1 a from the filling hole 1 d communicating with the supply pipe 6.

  During the filling of the slurry, the inside of the filling space 1a is sucked by the fine suction holes 3a provided in the suction head 3. By this suction, the volatile solvent is separated from the pressurized slurry in the filling space 1a, and is absorbed by the absorbent sheet 4 and released to the outside through the suction hole 3a. As a result, the volatile solvent in the slurry is removed, and the slurry having fluidity changes to a solidified state or a semi-solidified state. The suction removal of the volatile solvent may be performed only by the absorbent sheet 4. In this case, a plate-like member having no suction hole 3 a may be used instead of the suction head 3.

  Next, as shown in FIG. 3, the upper surface of the slurry filled in the filling space 1 a is moved to the lower surface of the suction head 3 by moving the frame 1 (the decorative dish 2) relative to the suction head 3. It is cut off by. This makes the exposed surface of the slurry uniform. The above-described steps complete the quantitative filling of the slurry.

  After that, as shown in FIG. 4, the solidified or semi-solidified slurry filled in the filling space 1a is pressed by the press head 7 disposed immediately above the absorbent sheet 4 '. As a result, the slurry that has been raised to the level equivalent to the flat surface 1c of the frame 1 is compressed. The surface of the compressed slurry is flush with the upper edge of the decorative plate 2, and the filling marks in the filling holes 1d disappear. Finally, a wet cosmetic as a final product is completed by performing a drying process for drying the volatile solvent remaining in the slurry as necessary.

  Thus, according to the present embodiment, the number of steps can be reduced by side-filling the slurry into the filling space 1 a including the decorative dish 2. This is because when a slurry casting is generated by preliminary casting and then transferred to a decorative dish, the decorative dish needs to be transferred, but according to the present embodiment, this operation is not necessary. Because it becomes. And since this transfer work becomes unnecessary, the problem of the collapse of the punched article accompanying the transfer can be solved, which contributes to the improvement of the yield.

  Further, according to the present embodiment, the working efficiency can be improved by making the position of the filling hole 1d on the side of the filling space 1a higher than the upper edge of the vanity plate 2. When the position of the filling hole 1d is set lower than the upper edge of the dressing plate 2, the space between the filling hole 1d and the filling space 1a is blocked by the side portion of the dressing plate 2, so that both can communicate with each other. As a result, a separate work for sealing the through hole with a seal after filling with the slurry is required. On the other hand, according to the present embodiment, it is not necessary to provide a through hole in the vanity plate 2 by devising the position of the filling hole 1d, so that such an operation is not necessary.

  In the above-described embodiment, the case where the slurry filled in the filling space 1a is rubbed with the covering surface (flat surface) corresponding to the lower surface of the suction head 3 has been described. However, the cutting of the slurry is not essential for molding, and the frame 1 (dressing plate 2) may be moved after the suction head 3 is raised. In this case, the covering surface of the suction head 3 does not have to be flat, and any surface shape including a concave shape as shown in FIG. 5 can be used. Further, in this case, it is sufficient that the size of the covering surface is substantially the same as the opening diameter of the filling space 1a exposed from the flat surface 1c. In the figure, the same members as those in FIG. 2 are denoted by the same reference numerals, and description thereof is omitted here. In this way, if a three-dimensional coating surface that is not flat is used, the surface of the wet cosmetic can have a shape interestingness (for example, a dome shape), so that a more differentiated wet cosmetic is obtained. be able to.

  As described above, the side filling according to the present invention can be widely applied to various wet cosmetics such as foundations, face powders, and eye shadows.
