Reference numeral 18 denotes a lipstick sample formed by solidifying the lipstick bulk 17 into a predetermined shape in the molding container 2 (see FIGS. 6 and 10).

  The molding jig 1 for the lipstick sample 18 according to the first embodiment has the above-described configuration. Next, a method for molding the lipstick sample 18 using the molding jig 1 will be described with reference to FIGS. It explains using.

  First, the molded container 2 is inserted from the lower side of the container accommodation hole 12 with the opening facing upward, and the upper side of the cylindrical mold 3 is inserted into the container insertion hole 11. At this time, the container insertion hole 11 can be in contact with the contact peripheral surface 3 </ b> D that is the upper portion of the cylindrical mold 3 over the entire circumference. Then, the bottom plate portion 6 is attached to the lower side of the container surrounding holder 8 to fix the molded container 2 in the upward and downward directions, and the bulk guide 14 is set to the upper side of the container surrounding holder 8 as shown in FIG. Can complete the preparatory work.

  When the preparatory work is completed in this way, the filling process of the lipstick bulk 17 is started. In this filling step, for example, the lipstick bulk 17 melted by heating to 80 to 100 ° C. is used to fill the lipstick filling hole 10 provided in the filling port 14A of the bulk guide 14 and the container enclosure holder 8 as shown in FIG. Then, a predetermined amount is filled into the molding container 2.

  Next, when a predetermined amount of lipstick bulk 17 is filled in the molded container 2, the process proceeds to a solidification process for the lipstick bulk 17. In this solidification step, the molding jig 1 filled with the lipstick bulk 17 is allowed to cool, for example, at a room temperature of 23 to 27 ° C. for about 1 minute 30 seconds to 2 minutes 30 seconds, and then set to −9 to −5 ° C. Place in the freezer for about 30 seconds to 1 minute 30 seconds to cool. Or, for example, it is allowed to cool for 5 minutes 30 seconds to 6 minutes 30 seconds at a room temperature of 23 to 27 ° C.

  At the time of this cooling, as shown in FIG. 8, the upper cooling portion 15 that is in contact with the contact peripheral surface 3D of the cylindrical mold 3 that is the upper portion of the molded container 2 through the container insertion hole 11 is filled in the molded container 2. The heat of the upper portion 17A of the lipstick bulk 17 is actively released from the contact peripheral surface 3D to the container holder 5 side as indicated by arrow A, and only the upper portion 17A of the lipstick bulk 17 is cooled to lower the temperature.

  In the solidification step, the air layer portion 16 formed around the lower portion of the molded container 2 gradually decreases the temperature of the lower portion 17B of the lipstick bulk 17 filled in the molded container 2, The temperature of the lower part 17B of the lipstick bulk 17 is cooled in a state higher than that of the upper part 17A.

  Thereby, in the solidification process, heat convection due to a temperature difference between the upper portion 17A and the lower portion 17B of the lipstick bulk 17 in the molded container 2, more specifically, from the lower side of the lipstick bulk 17 as shown by arrow B, By generating thermal convection upward and from the center toward the outer peripheral side, the lipstick bulk 17 can be solidified while stirring a pigment having a high specific gravity such as mica and metal powder.

  Next, when the lipstick bulk 17 is solidified to some extent, the lipstick bulk 17 overflowing the bulk receiver 14B of the bulk guide 14 is scraped, and the bulk guide 14 is removed from the container surrounding holder 8 as shown in FIG.

  Then, when the bulk guide 14 is removed from the container surrounding holder 8, the upper end portion of the lipstick bulk 17 protruding from the convex portion 8A of the container surrounding holder 8 is horizontally cut along the convex portion 8A to obtain FIG. As shown, a lipstick sample 18 can be molded into the molded container 2. The lipstick sample 18 thus molded can be taken out together with the molded container 2 as shown in FIG. 6 by removing the bottom plate portion 6 from the container surrounding holder 8.

  Further, the cut 18A of the lipstick sample 18 molded as described above is measured using a spectrophotometer or the like. In this case, the lipstick sample 18 according to the present embodiment can be formed with high quality because there is little variation in hue, lightness, and saturation because the pigment having a high specific gravity is distributed uniformly throughout.

  Therefore, a plurality of types, for example, four types of lipstick samples 18 are prepared by the molding method described above, and the results of colorimetry for each lipstick sample 18 are shown in Tables 1 and 2 below.

  First, Table 1 shows the blending ratio of each raw material constituting the lipstick bulk 17. Specifically, the lipstick bulk 17 contains mica titanium, pigment, wax, liquid oil, heavy liquid isoparaffin, and petroleum jelly. And the lipstick bulk 17 prepares four types (samples 1-4) from which a raw material compounding ratio differs, and creates the lipstick sample 18 with the shaping | molding method mentioned above.

  Table 2 shows three samples (samples 1 to 3) of lipstick samples 18 of samples 1 to 4, and three chromatic colors (hue, brightness, and saturation) for samples 1 to 3. The result of measuring with a spectrophotometer is shown. Based on this measurement result, by comparing the measured values of the three lipstick samples 18 made of the same sample, the difference between the maximum value and the minimum value can be determined as the quality.

  And by observing the maximum and minimum differences in Table 2 above, it can be seen that all the values of Samples 1 to 4 are 0.1 or less. From this, it is confirmed that the lipstick sample 18 produced by the molding method according to the first embodiment is of a high quality in which mica titanium, pigments and the like are uniformly dispersed throughout and the whole has a constant color. it can.

  Thus, according to the first embodiment, the upper cooling unit 15 can cool only the upper portion 17A of the lipstick bulk 17 filled in the molding container 2 and quickly lower the temperature. On the other hand, the air layer portion 16 can cool the lower portion 17B at a higher temperature than the upper portion 17A by gradually lowering the temperature of the lower portion 17B of the lipstick bulk 17. Thereby, in the lipstick bulk 17 filled in the molding container 2, convection due to a temperature difference can be generated between the upper portion 17A and the lower portion 17B.

  As a result, even when the lipstick bulk 17 contains a pigment having a high specific gravity such as mica or metal powder, these pigments can be solidified while being stirred by convection, and the pigment is uniformly distributed throughout the lipstick bulk 17. The quality of the lipstick sample 18 can be improved.

  Next, FIGS. 11 to 14 show a second embodiment of the present invention. The feature of this embodiment is that a plurality of molded containers and upper cooling parts are arranged in a container holder to form a lipstick as a product.

  23 is a container holder that forms the main body of the molding jig 21. The container holder 23 has good thermal conductivity so that the lipstick bulk 28 filled in each molding container 22 can be cooled effectively. It is made of a metal material such as an aluminum material. Further, as shown in FIGS. 11 and 12, the container holder 23 is roughly constituted by a lower mold 24 and an upper mold 25 described later.

  Reference numeral 24 denotes a lower mold constituting the lower part of the container holder 23, and the lower mold 24 is formed as a rectangular parallelepiped elongated in the left and right directions. The lower mold 24 is provided with a plurality of bottomed container receiving holes 24A that open to the upper surface side, for example, two rows of eight, for example, a total of sixteen. The container housing hole 24 </ b> A is formed as a circular hole having a larger diameter than the molded container 22, and defines an air layer portion 27 described later around the lower portion of the molded container 22.

  An upper die 25 is attached to the upper side of the lower die 24. The upper die 25 is formed as a rectangular parallelepiped that is thin in the upper and lower directions and is elongated in the left and right directions. In addition, a container insertion hole 25 </ b> A is provided in an upper portion of the upper mold 25 at a position that is coaxial with each container receiving hole 24 </ b> A of the lower mold 24. On the other hand, the lower part of the upper mold 25 is provided with a flange fitting part 25B having an enlarged diameter which is located below the container insertion hole 25A and into which the collar part 22B of the molded container 22 is fitted.

  Reference numeral 26 denotes a plurality of upper cooling portions provided in the upper mold 25, and the upper cooling portions 26 are provided at positions around the respective container insertion holes 25A. Further, the upper cooling section 26 cools only the upper portion 28A of the lipstick bulk 28 filled in contact with the upper portion of the molded container 22 held by the container holder 23. Here, the upper cooling part 26 is in contact with the contact peripheral surface 22C provided in the upper part of the molded container 22 over the entire periphery via the container insertion hole 25A.

  Then, the upper cooling unit 26 contacts the contact peripheral surface 22C of the molding container 22 via the container insertion hole 25A, and thereby heats the upper part 28A of the lipstick bulk 28 filled in the molding container 22 to the upper mold 25. The upper part 28A of the lipstick bulk 28 can be quickly cooled by letting it escape to the lower mold 24.

  Reference numeral 27 denotes a plurality of air layer portions provided below the upper cooling portion 26 and provided between the lower mold 24 of the container holder 23 and the forming container 22, and the air layer portion 27 includes the forming container 22.

That is, the air layer portion 27 is formed as a cylindrical air layer defined between the container receiving hole 24 </ b> A of the lower mold 24 and the lower portion of the molded container 22.

  Thereby, the air layer part 27 prevents the heat of the lower part 28B of the lipstick bulk 28 filled in the molded container 22 from directly escaping to the container holder 23 side, and the lower part of the lipstick bulk 28 The temperature of 28B can be lowered gradually. As a result, the lipstick bulk 28 in the molding container 22 can be cooled in a state where the temperature of the lower portion 28B is higher than that of the upper portion 28A.

  Here, 28 shows the lipstick bulk melted by heating (see FIG. 13). Reference numeral 29 denotes a lipstick product in which the lipstick bulk 28 is solidified and molded into a predetermined shape in the molding container 22 (see FIG. 14).

  The molding jig 21 for the lipstick product 29 according to the second embodiment has the above-described configuration. Next, a molding method for the lipstick product 29 using the molding jig 21 will be described with reference to FIGS. I will explain.

  First, the filling process of the lipstick bulk 28 will be described. In this filling step, as shown in FIG. 12, a predetermined amount of lipstick bulk 28 melted by heating is filled into the molded container 22 held by the container holder 23 from the upper opening 22A.

  Next, when a predetermined amount of the lipstick bulk 28 is filled in the molding container 22, the process proceeds to a solidification process of the lipstick bulk 28. In this solidification step, as in the first embodiment, the molding jig 21 filled with the lipstick bulk 28 is allowed to cool, for example, by leaving it at room temperature 23 to 27 ° C. for about 1 minute 30 seconds to 2 minutes 30 seconds. Then, it is cooled for about 30 seconds to 1 minute and 30 seconds in a freezer set to -9 to -5 ° C. Or, for example, it is allowed to cool for 5 minutes 30 seconds to 6 minutes 30 seconds at a room temperature of 23 to 27 ° C.
