Description

  The present invention relates to a wet solid cosmetic manufacturing method and a wet solid cosmetic slurry filling apparatus, and more particularly, to front filling of a slurry.

  Patent Document 1 discloses a front filling method in which a slurry that is a main material of a wet solid cosmetic is filled into a filling space from above. Specifically, first, the decorative dish is accommodated in a filling space provided in the mold. Next, the upper opening of the filling space is covered with the lower surface of the filling head. Then, the slurry is filled into the filling space covered by the filling head by pouring the slurry from the spout provided on the lower surface of the filling head. In this filling process, the slurry is guided vertically downward through a slurry supply pipe passing vertically through the inside of the filling head, and then discharged directly downward from a spout opening opened on the lower surface of the filling head. The slurry discharged vertically downward is restricted in flow by the bottom of the filling space (inner bottom of the vanity) located immediately below the spout, and then spreads horizontally along the bottom while filling the filling space. To fill the whole without gaps.

JP 2006-199616 A

  In Patent Document 1 described above, since the discharge direction of the slurry from the spout is vertically downward (vertical direction), the flow of the slurry is restricted by the bottom of the filling space. In this case, the method of applying the filling pressure in the filling space tends to be uneven, and in particular, the filling pressure in the vicinity of the spout tends to increase locally. The uneven filling pressure is not preferable because the hardness of the entire wet solid cosmetic becomes uneven and causes a decrease in strength and color unevenness. As a countermeasure, a method of providing a spout on the side of the tip portion of the slurry supply pipe and directing the slurry discharge direction to the side can be considered. However, in this case, when the slurry is discharged from the spout, the load tends to concentrate on the tip portion of the slurry supply pipe. Particularly, when the discharge of the highly viscous slurry is repeated over a long period of time, the durability of the tip portion is remarkably increased. May decrease.

  This invention is made | formed in view of this situation, The objective is to reduce the load added to the front-end | tip part of a slurry supply pipe | tube in the front filling of a slurry.

  In order to solve such a problem, the first invention includes a first step of accommodating a decorative dish in a filling space provided in a mold, and an upper opening of the filling space in which the decorative dish is accommodated. The slurry serving as the main material of the wet solid cosmetic is from a second step that covers the lower surface of the filling head, and a spout that opens at the lower surface of the filling head and communicates with the slurry supply pipe that is bent obliquely downward near the lower surface. There is provided a method for producing a wet solid cosmetic comprising a third step of filling slurry in a filling space by being discharged obliquely downward.

  Here, in the first invention, after the slurry is filled in the filling space, a fourth step of scraping the slurry filled in the filling space by a relative lateral displacement between the filling head and the filling space is performed. Further, it may be provided. Further, a fifth step of pressing the slurry filled in the filling space using a press head after the slurry is scraped off may be further provided.

  2nd invention provides the filling apparatus of the slurry for wet solid cosmetics which has a filling head, a slurry supply pipe | tube, and a spout. A filling head has a lower surface shape which covers the upper opening of the filling space with which the slurry used as the main material of wet solid cosmetics is filled. The slurry supply pipe penetrates the inside of the filling head so as to reach the lower surface of the filling head, and is bent obliquely downward in the vicinity of the lower surface. The spout is open on the lower surface of the filling head and discharges the slurry supplied to the slurry supply pipe into the filling space.

  According to the present invention, the slurry is discharged obliquely downward from the spout that is open on the lower surface of the filling head and communicates with the slurry supply pipe bent obliquely downward near the lower surface. Thereby, compared with the case where a spout is provided in the side of the front-end | tip part of a slurry supply pipe, it becomes possible to reduce the load added to this front-end | tip part by a shape device.

  Hereinafter, the manufacturing method of the wet solid cosmetics which concerns on this embodiment is demonstrated in order of the process shown in FIGS. The wet solid cosmetic is a powder solid makeup cosmetic such as foundation, face powder, and eye shadow, which is solidified by absorbing and drying a volatile solvent in the slurry. The slurry is a main material of the wet solid cosmetic, that is, a main material, and is a fluid obtained by mixing a cosmetic base material with a volatile solvent such as ethanol, water, liquid paraffin, isoparaffin, isopropyl alcohol. Wet solid cosmetics have the characteristics of a smooth touch, superior sensory characteristics such as fit, and excellent impact resistance compared to dry solid cosmetics that are directly cast from powder cosmetics. .

  First, as shown in FIG. 1, a substantially rectangular dish-shaped decorative dish 2 is set in a storage space 1 a provided in the mold 1. The mold 1 serving as a holding body for the decorative dish 2 is formed of a hard member in order to appropriately hold the decorative dish 2 in a series of work steps. In addition, in anticipation of a decrease in the height of the filling due to the subsequent press, the upper edge of the decorative dish 2 is lower than the depth of the accommodation space 1a (the upper surface of the mold 1). The storage space 1a in which the decorative tray 2 is stored corresponds to a slurry filling space that is a filling material, and in the next front filling step, the filling space 1a is filled with the slurry.

  Next, as shown in FIG. 2, the mold 1 on which the decorative dish 2 is set is disposed immediately below the filling device 3. The filling device 3 has a filling head 3a that can be raised and lowered by a drive mechanism (not shown), and a slurry supply pipe 3b to which slurry discharged from a pump (not shown) is supplied is attached to the filling head 3a. The filling head 3a has a lower surface shape that covers the upper opening of the filling space 1a. Moreover, as a material of the filling head 3a, a hard member such as metal or Duracon resin may be used, but an elastic body may be used for the purpose of improving the sealing property of the filling space 1a. In the present embodiment, a slurry supply pipe 3b is fixedly attached to the filling head 3a. The slurry supply pipe 3b vertically penetrates the inside of the filling head 3a so as to reach the lower surface of the filling head 3a, and its tip portion (near the lower surface of the filling head 3a) is bent obliquely downward. . The tip portion of the slurry supply pipe 3b is substantially flush with the lower surface of the filling head 3a without protruding downward from the lower surface of the filling head 3a. The spout 3c is open on the lower surface of the filling head 3a and communicates with the slurry supply pipe 3b that is bent obliquely downward. Therefore, the spout 3c discharges the slurry obliquely downward. The filling head 3a is provided with at least one suction hole 3d at a portion corresponding to the filling space 1a. Each suction hole 3d passes straight through the top and bottom of the filling head 3a, and communicates with an air chamber (not shown) attached above the filling head 3a.

  Next, as shown in FIG. 3, the filling head 3a is lowered to cover the upper opening of the filling space 1a with the lower surface of the filling head 3a, and then the slurry is slanted downward from the spout 3c with a predetermined discharge pressure. Discharge. The slurry discharged obliquely downward reaches the entire filling space 1a while expanding inside the filling space 1a. At that time, the volatile solvent that has oozed out of the slurry by the pressurization is sucked and removed into the air chamber through the suction hole 3d. The suction / removal may be performed after an air-permeable absorbent sheet (not shown) is interposed between the lower surface of the filling head 3 a and the upper surface of the mold 1.

  FIG. 6 is an explanatory diagram of the discharge direction of the slurry discharged from the spout 3c. The figure is a two-dimensional plane (XY plan view) of the filling space 1a in which the vanity plate 2 is accommodated as viewed from above, and shows the shape of the upper opening of the filling space 1a. In the present embodiment, the spout 3c is premised to open obliquely downward, but is arranged so as to further satisfy the following two conditions from the viewpoint of increasing the degree of freedom of slurry flow. (However, these are not essential for the configuration of the present invention).

(Arrangement conditions of spout 3c)
(1) The spout 3c is provided at a position offset in the horizontal direction from the center C of the filling space 1a. (2) The spout 3c is open to the center C side of the filling space 1a.

  In FIG. 6, when the coordinates of the center C of the filling space 1a are (Xc, Yc) and the coordinates of the spout 3c are (X1, Y1), the spout 3c is (X1-Xc) on the right side of the center C. And (Yc−Y1) are offset downward. In this case, the center C side is a direction from X1 to Xc in the X direction, and a direction from Y1 to Yc in the Y direction. Therefore, when viewed on the XY plane, the hatched area is on the center C side, and the discharge direction of the spout 3c is within that range.

  By arranging the spout 3c so as to satisfy the above conditions (1) and (2), it is possible to increase the uniformity of the slurry filling pressure in the filling space 1a. First, as described above, since the spout 3c is opened obliquely downward, the discharge direction of the slurry from the spout 3c is directed toward the center C instead of vertically downward. Therefore, since the degree of flow restriction by the bottom of the filling space 1a located directly below the spout 3c is reduced, the degree of freedom of slurry flow can be increased. Second, by discharging the slurry to the center C side, it is difficult for flow restriction by the side wall portion of the filling space 1a to occur. Discharging the slurry to the center C side means that the slurry is discharged to the wide side where the distance to the side wall portion in the filling space 1a is long and the space is sufficient. Therefore, the flow restriction by the side wall portion is reduced rather than discharging to the narrow side where the distance to the side wall portion is short and there is not enough space, and the degree of freedom of flow in the horizontal direction is increased accordingly.

  Next, as shown in FIG. 4, the filling head 3 a is moved while the slurry filled in the filling space 1 a is scraped off by the lower surface of the filling head 3 a by displacing the mold 1 relative to the filling device 3. Take away. As a result, the slurry is quantitatively filled into the filling space 1a.

  Then, as shown in FIG. 5, the slurry filled in the filling space 1 a is pressed to a height corresponding to the upper edge of the decorative dish 2 using the press head 4. Thereby, the wet solid cosmetic as the final product is completed.

  As described above, according to the present embodiment, the slurry is discharged obliquely downward from the spout 3c that is open on the lower surface of the filling head 3a and communicates with the slurry supply pipe 3b that is bent obliquely downward near the lower surface. Thereby, it is possible to reduce the load applied to the tip portion of the slurry supply pipe 3b by a geometric device. Here, as a comparative example, when the tip of the slurry supply pipe 3b is closed and the spout 3c is provided on the side of the tip portion, the discharge pressure of the slurry is directly and continuously applied to the portion where the tip is blocked. Therefore, the durability of this part becomes a problem. On the other hand, if the slurry supply pipe 3b is bent obliquely downward and the discharge direction of the spout 3c is made obliquely downward as in the present embodiment, the discharge pressure is received by the entire bent inner wall of the slurry supply pipe 3b. As a result, the portion to which the discharge pressure is applied can be dispersed. Such an effect is particularly remarkable in a situation where the discharge of a highly viscous slurry is repeated over a long period of time.

  In the above-described embodiment, the mode of discharging the slurry to the side or obliquely downward has been described. However, as long as such a discharge direction is maintained, a small-diameter discharge port directed in the direct lower direction is allowed to coexist. Also good.

  The present invention can be widely applied to a front filling method in various wet solid cosmetics (whether monochromatic or multicolored) such as foundation, face powder, and eye shadow.
