Description

[Technical Field]

[0001] The present invention relates to an apparatus for manufacturing a stick-type cosmetic product and a method for manufacturing a stick-type cosmetic product. [Background technology]

[0002] Cosmetic sticks have been available for some time. Conventional methods for producing cosmetic sticks include, for example, (1) a technique of filling a mold, molding, and fixing the molded product to a container, (2) a technique of directly filling a stick-shaped container and molding, and (3) a technique of filling a resin mold or a rubber mold, molding, and fixing the molded product to a container. For example, Patent Document 1 discloses a container for cosmetic sticks that employs a so-called back-filling method, in which a cosmetic melted by heating is directly filled into the container from the bottom of the container and then cooled and solidified. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5260099 Summary of the Invention [Problem to be solved by the invention]

[0004] For example, multi-colored stick-type cosmetics are known, but they have problems such as the inability to clearly distinguish the boundaries between colors and the complexity of the manufacturing equipment. Similar problems are expected when manufacturing stick-type cosmetics with different properties, including colors.

[0005] An object of the present invention is to provide a technique relating to an apparatus or method for producing a stick-type cosmetic product that allows for clear boundary distinction using a method that is simpler than conventional methods. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention comprises the following means: That is, the present invention is a manufacturing device for a stick-shaped cosmetic product, which comprises a filling section in which the area where the cosmetic product is filled is stick-shaped, and a dividing section that is provided inside the filling section and divides the inside of the filling section when the cosmetic product is filled, the dividing section being cylindrical and dividing the inside of the filling section into an inside and an outside.

[0007] According to the manufacturing apparatus for stick-type cosmetics of the present invention, the interior of the filling section can be divided by providing a dividing section. Furthermore, because the dividing section is cylindrical, cosmetics of different properties can be filled inside and outside the dividing section with clear distinction. The dividing section may be cylindrical, and examples thereof include circular and polygonal shapes. The outer shape of the filling section is not particularly limited, as long as the area where the cosmetics are filled is rod-shaped. Examples of cosmetics of different properties include cosmetics of different colors and cosmetics of different ingredients. Examples of cosmetics include lipstick and lip balm. The manufacturing apparatus for stick-type cosmetics of the present invention has a simple configuration in which the interior of the filling section is divided by a dividing section, yet can manufacture stick-type cosmetics in which cosmetics of different properties are clearly arranged on the inside and outside. The manufacturing apparatus for stick-type cosmetics of the present invention can be applied to various conventional manufacturing apparatuses. Examples of various conventional manufacturing equipment include direct filling molding manufacturing equipment that directly fills cosmetics into stick-type cosmetic containers, manufacturing equipment that molds stick-type cosmetics using a mold, and resin / rubber mold filling manufacturing equipment that fills cosmetics into resin or rubber molds.

[0008] Here, the divided portion may further include a rod-shaped portion inserted into the divided portion. When filling the cosmetic, there is a concern that the cosmetic may be filled into the divided portion. However, by filling the cosmetic with the rod-shaped portion inserted into the divided portion, the cosmetic can be filled into the area of the filling portion other than the area where the divided portion and rod-shaped portion are inserted. After filling the cosmetic, the divided portion and rod-shaped portion are removed, and then cosmetic materials of different properties are filled. This makes it possible to produce a rod-shaped cosmetic in which cosmetic materials of different properties are clearly separated between the inside and outside. For example, it is possible to use a rod-shaped member instead of the cylindrical divided portion. However, in this case, there is a concern that back pressure, in other words, the vacuum effect, when the rod-shaped member is pulled out may cause chips, dents, cracks, holes, etc., to occur in the cosmetic filled on the outside, particularly at the tip. Such cosmetic defects due to back pressure become more pronounced as the diameter of the rod-shaped member increases and the thickness of the cosmetic filled on the outside decreases. By making the divided section cylindrical, air can be easily removed, and cosmetic defects caused by back pressure are less likely to occur. Furthermore, by inserting a rod-shaped section into the divided section, it is possible to prevent the cosmetic from filling the divided section, or in other words, from flowing in, as described above. As a result, it is possible to produce a stick-shaped cosmetic in which cosmetics with different properties are clearly separated and arranged on the inside and outside. The shape and diameter of the rod-shaped section are not limited as long as it can prevent the cosmetic from flowing into the cylindrical divided section. By matching the outer shape of the tip of the rod-shaped section to the inner shape of the tip of the cylindrical divided section, it is possible to effectively prevent the cosmetic from flowing into the cylindrical divided section.

[0009] The tip of the dividing section may also be tapered. By forming the tip of the dividing section into a tapered shape, it is possible to reduce the resistance when removing (pulling out) the dividing section. This also allows air to escape more easily, preventing air from accumulating at the tip of the dividing section. As a result, it is possible to improve the quality of the produced cosmetic product and also to more clearly distinguish the boundaries of the cosmetic product.

[0010] Here, in the stick-type cosmetic manufacturing apparatus according to the present invention, the filling section is part of the stick-type cosmetic container, and the stick-type cosmetic manufacturing apparatus may further include a container support section that supports the stick-type cosmetic container, and a dividing support section that is connected to the container support section and supports the dividing section.

[0011] By making the filling section part of the stick-type cosmetic container, the manufacturing apparatus for stick-type cosmetics according to the present invention can be used as a direct filling molding manufacturing apparatus that directly fills cosmetics into the stick-type cosmetic container. By providing a container support section, the stick-type cosmetic container can be stably supported. Furthermore, by providing a divided support section, the divided section can be stably supported. Examples of stick-type cosmetic containers include lipstick cosmetic containers and lip balm cosmetic containers.

[0012] The manufacturing device for stick-type cosmetic material according to the present invention may further include a tubular filling collar connected to the stick-type cosmetic container so as to communicate with the filling section. The filling collar allows the cosmetic material to be filled up to a position above the upper end of the filling section. The filling collar may have a stepped portion provided on the inside and configured to engage with the upper end of the filling section. The filling collar may also have a tapered end portion with an obliquely cut upper end.

[0013] Here, a known method for manufacturing stick-type cosmetics is the so-called bag-filling method, in which a heated and melted cosmetic is directly filled into the bottom of a container and then cooled and solidified. Even with the bag-filling method, there is a concern that dents may occur on the surface of the filled cosmetic due to concentrated shrinkage distortion. To prevent such dents, the bag-filling method involves remelting the filled cosmetic by irradiating it with high-temperature heat using a hot air nozzle or heater. Repeated heating and cooling can lead to uneven crystal structures, potentially resulting in quality degradation. Furthermore, repeated heating and cooling can complicate the process. The bag-filling method also requires repeated heating and cooling, potentially resulting in uneven crystal structures, potentially resulting in quality degradation. Furthermore, the bag-filling method requires heat to be irradiated through a hole in the bottom of the container, making the process complicated.

[0014] The manufacturing device for stick-type cosmetics according to the present invention includes a filling collar, which allows the cosmetic to be filled so that it exceeds the upper end of the filling section, in other words, the cosmetic can be overfilled. With the manufacturing device for stick-type cosmetics according to the present invention, even if a depression (also known as a sink mark) occurs on the surface of the filled cosmetic due to concentrated shrinkage strain, the tip where the depression occurred can be cut off, improving the quality of the manufactured cosmetic. The cut-off excess portion can be reused. Furthermore, stick-type cosmetics can be easily manufactured simply by connecting the filling collar to the filling section of the cosmetic container. Furthermore, in the bag-filling method, heat must be applied through a hole in the bottom of the container to prevent depressions from occurring, which requires the hole in the bottom of the container to be enlarged. Therefore, while the bag-filling method may be subject to restrictions on the shape of the container, the present invention does not impose such restrictions on the shape of the container. Furthermore, the filling collar has a stepped portion, which positions the filling collar and ensures a secure connection between the filling collar and the main body. Furthermore, the tapered end of the filling collar provides a larger opening area and facilitates filling compared to when the tip of the filling collar is horizontal, thereby improving productivity.

[0015] The container support part may support the cosmetic container so that the tip of the tapered dividing part is horizontal. In other words, the container support part may support the cosmetic container so that the tapered end is horizontal when the container for stick-type cosmetic is tilted. This makes it easier to fill the cosmetic.

[0016] Here, in the apparatus for manufacturing a stick-type cosmetic product according to the present invention, the filling unit may comprise a mold unit into which the cosmetic product is filled. By using the mold unit as the filling unit, the apparatus for manufacturing a stick-type cosmetic product according to the present invention can be used as a manufacturing apparatus that molds stick-type cosmetics using a mold. The mold unit can be composed of, for example, multiple parts. Providing multiple parts increases the degree of freedom in designing the stick-type cosmetic product.

[0017] Furthermore, in the apparatus for manufacturing stick-type cosmetics according to the present invention, the filling unit may consist of a resin mold unit made of resin into which the cosmetic is filled. By using a resin molding unit as the filling unit, the apparatus for manufacturing stick-type cosmetics according to the present invention can be used as a manufacturing apparatus for resin / rubber mold filling, in which the cosmetic is filled into a resin or rubber mold or ogive. The resin mold unit can be composed of, for example, multiple parts. Providing multiple parts increases the degree of freedom in designing the stick-type cosmetics.

[0018] In addition, in the manufacturing apparatus for stick-shaped cosmetics according to the present invention, the dividing section may have an internal jig that suppresses the filling of the cosmetic by filling part of the interior of the filling section so as to run vertically or transversely through the interior of the filling section.

[0019] By providing an internal jig, it is possible to fill the cosmetic material in the area inside the filling section other than the area where the internal jig is inserted. Cutting the interior of the filling section vertically or transversely means dividing the interior wall of the filling section in a line. The linear division may be either straight or curved. After filling the cosmetic material, the internal jig is removed and cosmetic materials of different properties are filled, thereby producing a stick-shaped cosmetic material in which cosmetic materials of different properties are clearly distinguished and arranged vertically or transversely inside the filling section.

[0020] Furthermore, in the apparatus for producing a stick-type cosmetic material according to the present invention, the dividing section may further include a jig fixing section that fixes the position of the internal jig. By providing the jig fixing section, the position of the internal jig can be easily fixed.

[0021] The present invention may also be specified as a method for producing a stick-shaped cosmetic product. For example, the present invention is a method for producing a filled cosmetic product, including a filling step of filling a stick-shaped filling portion with a cosmetic product and a slow cooling step of slowly cooling the filled cosmetic product, in which in the filling step, a cylindrical dividing portion that divides the inside of the filling portion is inserted into the filling portion, dividing the inside of the filling portion into an inner and outer portion, and filling the cosmetic product therein.

[0022] According to the method for producing a stick-type cosmetic product of the present invention, the interior of the filling section can be divided by a dividing section. Furthermore, because the dividing section is cylindrical, cosmetics of different properties can be clearly distinguished and filled inside and outside the dividing section. The method for producing a stick-type cosmetic product of the present invention can produce a stick-type cosmetic product in which cosmetics of different properties are clearly distinguished and arranged inside and outside, by the simple method of dividing the interior of the filling section by a dividing section.

[0023] Furthermore, in the filling step, the cosmetic may be filled with the rod-shaped portion inserted into the divided portion. This allows the cosmetic to be filled into the area inside the filling portion other than the area where the divided portion and rod-shaped portion are inserted. After filling with the cosmetic, the divided portion and rod-shaped portion are removed, and then a cosmetic of different properties is filled, thereby producing a rod-shaped cosmetic in which the cosmetics of different properties are clearly arranged on the inside and outside. [Effects of the Invention]

[0024] According to the present invention, it is possible to provide a technique relating to an apparatus or method for producing a stick-type cosmetic product, which allows for a clear boundary to be distinguished using a simple method. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0026] Next, an embodiment of the present invention will be described with reference to the drawings. The following description is an example, and the present invention is not limited to the following content.

[0027] First Embodiment <Device configuration> As shown in Figures 1 to 4 and 5 to 9, the manufacturing apparatus 1 for stick-type cosmetics according to the first embodiment includes a cosmetic container 2 (an example of a filling section of the present invention), a center pipe 3 (an example of a dividing section of the present invention), a center round bar 4 (an example of a rod-shaped section of the present invention), a container holder 5 (an example of a container support section of the present invention), and a centering jig 6 (an example of a dividing support section of the present invention). The container holder 5 includes an upper container mold 51 and a lower container mold 52. The centering jig 6 includes a center round bar stay 61 and a stand stay 62.

[0028] The cosmetic container 2 (an example of a filling section of the present invention) is a so-called stick-shaped cosmetic container, and by rotating a cylindrical filling section 21 and a rotating section 22 connected to the filling section 21 relative to each other, the stick-shaped cosmetic filled in the filling section 21 can be inserted into and removed from the filling section 21. In detail, the cosmetic container 2 includes the filling section 21, the rotating section 22, a lifting section (not shown), and an outer cylindrical section (not shown). The filling section 21 is cylindrical, has an open tip, and is filled with the cosmetic. The filling section 21 of this embodiment has a tapered shape with an obliquely notched tip. The tip of the filling section 21 may also have a horizontally notched shape. The rotating section 22 is connected to the base end of the filling section 21 and is rotatable relative to the filling section 21, with the central axis of the filling section 21 as the reference. The lifting unit is provided inside the rotating unit 22 and moves up and down, or in other words, slides, within the rotating unit 22 and the filling unit 21 along the axial direction of the filling unit 21 in conjunction with the rotation of the rotating unit 22. The base of the cosmetic material is connected to the lifting unit, and as the lifting unit moves up and down, the stick-shaped cosmetic material slides, or in other words, can be put in and taken out of the filling unit 21. The outer tube is cylindrical and slightly larger than the filling unit 21, with a closed end, and functions as a cap for the stick-shaped cosmetic container. The cosmetic container 2 need only be able to be filled with stick-shaped cosmetic material, and various existing stick-shaped cosmetic materials can be used.

[0029] The center pipe 3 (an example of a cylindrical dividing portion of the present invention) is provided inside the filling portion 21 and divides the interior of the filling portion 21 when the cosmetic is filled. By providing the center pipe 3 inside the filling portion 21 when the cosmetic is filled, different types of cosmetic can be clearly distinguished and filled inside and outside the center pipe 3. Examples of cosmetics include lipstick and lip balm, but the cosmetics are not limited to these. Any cosmetic may be used as long as it can be molded into a stick shape. Examples of cosmetics with different properties include cosmetics with different colors and cosmetics with different ingredients. The center pipe 3 according to the first embodiment has an elongated cylindrical shape. The cross-sectional shape of the center pipe 3 may be other than circular, such as triangular, rectangular, or star-shaped. The center pipe 3 according to the first embodiment also has a tapered tip. This reduces resistance when the center pipe 3 is pulled out of the filling portion 21. Furthermore, the tapered tip of the center pipe 3 allows air to escape more easily, thereby preventing air from accumulating at the tip of the center pipe 3.

[0030] The center round rod 4 (an example of a rod-shaped portion of the present invention) is inserted into the center pipe 3. By filling the center pipe 3 with a cosmetic while the center round rod 4 is inserted, the cosmetic can be filled into areas of the filling portion 21 other than the areas where the center pipe 3 and the center round rod 4 are inserted. The center round rod 4 is made of a rod-shaped member with a circular cross section and has an outer diameter smaller than the inner diameter of the center pipe 3. The cross-sectional shape of the center round rod 4 can be other than circular, such as triangular, rectangular, or star-shaped, depending on the cross-sectional shape of the center pipe 3. Note that the shape and diameter of the center round rod 4 are not limited as long as it can prevent the cosmetic from flowing into the center pipe 3. By matching the outer shape of the tip of the center round rod 4 to the inner shape of the tip of the center pipe 3, the cosmetic can be effectively prevented from flowing into the center pipe 3.

[0031] The container holder 5 (an example of a container support portion of the present invention) supports multiple cosmetic containers 2. The container holder 5 according to this embodiment includes a container upper mold 51 and a container lower mold 52. The container lower mold 52 supports the lower part of the cosmetic container 2. The container lower mold 52 includes a container lower mold base 521 formed of a rod-shaped rectangular parallelepiped, in other words, a plate-like member, and container lower mold columns 522 that rise from both ends of the container lower mold base 521 and support the container upper mold 51. The container lower mold base 521 is provided with multiple circular recesses 521a that accommodate the lower parts of the cosmetic containers 2. The container upper mold 51 supports the upper part of the cosmetic container 2. The container upper mold 51 is composed of a plate-like member that is parallel to the container lower mold base 521 and is connected to the upper part of the container lower mold columns 522. The container upper mold 51 is provided with a plurality of circular upper mold through-holes 51a through which the upper part of the cosmetic container 2 passes, at positions corresponding to the recesses of the container lower mold base 521. The recesses of the container lower mold base 521 may be through-holes, and the lower part of the cosmetic container 2 may be supported by the top surface of a table on which the container holder 5 is placed.

[0032] The centering jig 6 (an example of a split support part of the present invention) is connected to the top of the container holder 5 and supports the center pipe 3. The centering jig 6 includes a stand stay 62 and a center round bar stay 61. The stand stay 62 consists of a column located on an extension of the column 522 of the container lower mold. The center round bar stay 61 is parallel to the base 521 of the container lower mold and the container upper mold 51 and consists of a plate-like member connected to the top of the stand stay 62. The center round bar stay 61 has multiple circular stay through-holes 61a, through which the top of the center pipe 3 passes, at positions corresponding to the through-holes 51a of the base 521 of the container lower mold and the upper mold.

[0033] The container holder 5 may be configured to support one cosmetic container 2. Alternatively, the circular recess 521a of the base 521 of the container lower mold may be formed deep so that the cosmetic container 2 can be supported by the circular recess 521a alone. In this case, the container holder 5 can be configured with only the container lower mold 52, omitting the container upper mold 51, thereby achieving a simpler configuration.

[0034] <Manufacturing method> Next, a method for producing a filled cosmetic according to the first embodiment will be described. Figure 5 shows a flow diagram of the method for producing a filled cosmetic according to the first embodiment. The method for producing a filled cosmetic according to the first embodiment includes a first preparation step (S01), a first filling step (S02), a first gradual cooling step (S03), a second preparation step (S04), a second filling step (S05), a second gradual cooling step (S06), and a finishing step (S07). The first filling step and the second filling step are examples of the filling step of the present invention. The first gradual cooling step and the second gradual cooling step are examples of the gradual cooling step of the present invention.

[0035] In the first preparation step (S01), in preparation for the first filling step, a cosmetic container 2 is set in the container holder 5 (container lower mold 52) (see FIGS. 1, 2, and 6). More specifically, the lower part of the cosmetic container 2 is inserted into the recess of the base 521 of the container lower mold. Next, the container upper mold 51 is set. More specifically, the container upper mold 51 is connected to the upper part of the pillar 522 of the container lower mold. Note that after the container upper mold 51 is connected to the upper part of the pillar 522 of the container lower mold, the lower part of the cosmetic container 2 may be inserted into the recess of the base 521 of the container lower mold. Next, the centering jig 6 is set. More specifically, the centering jig 6 is connected to the upper part of the container holder 5. Next, the center round stay 61 and the stand stay 62 are set. More specifically, the lower part of the stand stay 62 is connected to the upper part of the pillar 522 of the container lower mold, and the center round stay 61 is connected to the upper part of the stand stay 62. The center round bar stay 61 may be connected to the upper part of the stand stay 62, and the lower part of the stand stay 62 to which the center round bar stay 61 is connected may be connected to the upper part of the column 522 of the container lower mold. Next, the center pipe 3 and the center round bar 4 are set. More specifically, the center pipe 3 is inserted into the through hole 61a of the center round bar stay 61, the through hole 51a of the upper mold of the container upper mold 51, and the filling section 21 of the cosmetic container 2. Next, the center round bar 4 is inserted into the through hole 61a of the center round bar stay 61, the through hole 51a of the upper mold of the container upper mold 51, and the filling section 21 of the cosmetic container 2 so as to be enclosed within the center pipe 3. Alternatively, the center round bar 4 may be enclosed within the center pipe 3, and the center pipe 3 containing the center round bar 4 may be inserted into the through hole 61a of the center round bar stay 61, the through hole 51a of the upper mold of the container upper mold 51, and the filling section 21 of the cosmetic container 2.

[0036] In the first filling step (S02), the cosmetic (outside) is filled (see FIG. 7). More specifically, the cosmetic is filled into the filling section 21 of the cosmetic container 2 and outside the central pipe 3, in other words, into the area between the inner surface of the filling section 21 and the outer surface of the central pipe 3. Filling can be performed using, for example, a dispenser.

[0037] In the first slow cooling step (S03), the cosmetic material filled on the outside is slowly cooled. The slow cooling time and the temperature after slow cooling are appropriately determined depending on the cosmetic material to be filled.

[0038] In the second preparation step (S04), preparations for the second filling step are made. More specifically, the center round rod 4 is removed from the center pipe 3. Next, the center pipe 3 is removed from the filling section 21 of the cosmetic container 2. The center round rod 4 and the center pipe 3 can be removed more smoothly by rotating them. Next, the centering jig 6 is removed from the container holder 5.

[0039] In the second filling step (S05), the cosmetic (center) is filled (see FIG. 8). More specifically, the cosmetic is filled into the filling section 21 of the cosmetic container 2 and into the area where the center round rod 4 was inserted. Filling can be performed using, for example, a dispenser. Note that, since the filling in the second filling step only requires filling into the center of the filling section 21, the filling in the second filling step may be performed without using a dispenser, for example, using a nozzle-type automatic filling machine. This further improves productivity.

[0040] In the second gradual cooling step (S06), the cosmetic material filled in the center is slowly cooled. The gradual cooling time and the temperature after gradual cooling are determined appropriately depending on the cosmetic material to be filled. In the second gradual cooling step, forced cooling may be performed, where necessary, at a temperature lower than that of gradual cooling so that the cosmetic material is solidified.

[0041] In the finishing step (S07), finishing is carried out. More specifically, first, excess cosmetic material is scraped off. The excess cosmetic material is the cosmetic material that spills out from the top of the cosmetic material container 2. Next, the top surface of the filled cosmetic material is formed, in other words, the top surface is finished. Once the formation of the top surface of the cosmetic material is complete, the cosmetic material container 2 is removed from the container holder 5, and the production of the cosmetic material is completed (see FIG. 9).

[0042] According to the manufacturing apparatus 1 for stick-type cosmetics of the first embodiment, the inclusion of the center pipe 3 allows the interior of the filling section 21 to be divided. Furthermore, because the center pipe 3 is cylindrical, cosmetics of different properties can be filled inside and outside the center pipe 3 with a clear distinction. The manufacturing apparatus 1 for stick-type cosmetics of the first embodiment has a simple configuration in which the interior of the filling section 21 is divided by the center pipe 3, yet is capable of manufacturing stick-type cosmetics in which cosmetics of different properties are clearly arranged on the inside and outside. Furthermore, the manufacturing apparatus 1 for stick-type cosmetics of the first embodiment is equipped with the center round rod 4, and by filling the cosmetics with the center round rod 4 inside the center pipe 3 with the center round rod 4 inserted, the cosmetics can be filled into the areas of the interior of the filling section 21 other than those into which the center pipe 3 and center round rod 4 are inserted. After filling the cosmetics, the center pipe 3 and center round rod 4 can be removed, and cosmetics of different properties can be filled, thereby manufacturing stick-type cosmetics in which cosmetics of different properties are clearly arranged on the inside and outside. For example, it is possible to use a rod-shaped member instead of the center pipe 3. However, in this case, there is a concern that back pressure, or in other words, a vacuum effect, when the rod-shaped member is pulled out may cause chips, dents, cracks, holes, etc. in the cosmetic material filled on the outside, especially at the tip. Such cosmetic material defects due to back pressure become more pronounced as the diameter of the rod-shaped member increases and the thickness of the cosmetic material filled on the outside decreases. Using the center pipe 3 makes it easier to remove air, making cosmetic material defects due to back pressure less likely to occur. Furthermore, inserting a central round rod 4 inside the center pipe 3 can prevent the cosmetic material from filling, or in other words, flowing, into the center pipe 3, as described above. As a result, a rod-shaped cosmetic material can be manufactured in which cosmetics with different properties are clearly arranged on the inside and outside.

[0043] Furthermore, the tapered tip of the center pipe 3 reduces resistance when the center pipe 3 is pulled out of the filling section 21. This also allows air to escape more easily, preventing air from accumulating at the tip of the center pipe 3. As a result, the quality of the produced cosmetic product can be improved, and the boundaries of the cosmetic product can be more clearly distinguished.

[0044] Second Embodiment <Device configuration> As shown in Figures 10 to 12, the manufacturing apparatus 1 for stick-type cosmetics according to the second embodiment differs from the manufacturing apparatus 1 for stick-type cosmetics according to the first embodiment in that the container holder 5 and centering jig 6 have simpler configurations than those of the first embodiment and also include a filling collar 7. Components similar to those of the manufacturing apparatus 1 for stick-type cosmetics according to the first embodiment are given the same reference numerals and will not be described again. The manufacturing apparatus 1 for stick-type cosmetics according to the second embodiment includes a cosmetic container 2 (an example of a filling section of the present invention), a center pipe 3 (an example of a dividing section of the present invention), a central round bar 4 (an example of a rod-shaped section of the present invention), a container holder 5 (an example of a container support section of the present invention), a centering jig 6 (an example of a dividing support section of the present invention), and a filling collar 7.

[0045] The container holder 5 does not include the upper container mold 51, and is composed of a container lower mold base 521 and a container lower mold pillar 522 as the lower container mold 52. The centering jig 6 does not include the stand stay 62, and is composed only of a center round rod stay 61. The upper part of the container holder 5 (the upper part of the lower container mold pillar 522) is connected to both ends of the center round rod stay 61.

[0046] The filling collar 7 is cylindrical and is connected to the stick-shaped cosmetic container so as to communicate with the filling portion 21. The filling collar 7 allows the cosmetic to be filled up to a position above the upper end of the filling portion 21. The filling collar 7 has a stepped portion 71 formed on the inside and configured as a step that engages with the upper end of the filling portion 21. The filling collar 7 also has a tapered end portion with an obliquely notched upper end. The upper end of the filling collar 7 may also have a horizontally notched shape.

[0047] <Manufacturing method> Next, a method for producing a filled cosmetic material according to the second embodiment will be described, focusing on the differences from the first embodiment. Like the first embodiment, the method for producing a filled cosmetic material according to the second embodiment includes a first preparation step (S01), a first filling step (S02), a first gradual cooling step (S03), a second preparation step (S04), a second filling step (S05), a second gradual cooling step (S06), and a finishing step (S07) (see FIG. 5).

[0048] In the first preparation step (S01), the filling collar 7 is connected to the filling portion 21 of the cosmetic container 2. The filling collar 7 may be connected to the filling portion 21 later. Next, the cosmetic container 2 is set in the container holder 5 (container lower mold 52), the centering jig 6 is set, the center round bar stay 61 is set, and the center pipe 3 and the center round bar 4 are set.

[0049] In the first filling step (S02), the cosmetic material (outside) is filled (see FIG. 13). Since the filling collar 7 is connected to the filling portion 21, the cosmetic material is filled so as to exceed the upper end of the filling portion 21.

[0050] In the first slow cooling step (S03), the cosmetic material filled on the outside is slowly cooled. In the second preparation step (S04), the center round rod 4 is removed from the center pipe 3, the center pipe 3 is removed from the filling portion 21 of the cosmetic container 2, and the centering jig 6 is removed from the container holder 5.

[0051] In the second filling step (S05), the cosmetic (center portion) is filled. As in the first filling step, since the filling collar 7 is connected to the filling portion 21, the cosmetic is filled so as to exceed the upper end of the filling portion 21.

[0052] In the second gradual cooling step (S06), the cosmetic material filled in the center is slowly cooled (see FIG. 14). The gradual cooling time and the temperature after gradual cooling are determined appropriately depending on the cosmetic material to be filled. In the second gradual cooling step, forced cooling may be performed, where necessary, at a temperature lower than that of gradual cooling, so that the cosmetic material is solidified.

[0053] In the finishing step (S07), finishing is carried out. Unlike the first embodiment, the filling collar 7 is separated from the filling portion 21. Next, the tip of the stick-shaped cosmetic material is cut. Examples of cutting methods include cutting with a wire or a knife. Next, if necessary, the top surface of the filled cosmetic material is shaped, in other words, top surface finishing is carried out. Once shaping of the top surface of the cosmetic material is complete, the cosmetic material container 2 is removed from the container holder 5, and the production of the cosmetic material is completed (see FIG. 9).

[0054] The stick-type cosmetic manufacturing apparatus 1 according to the second embodiment has a simpler configuration than the first embodiment, but can achieve the same effects as the stick-type cosmetic manufacturing apparatus 1 according to the first embodiment. That is, it is possible to manufacture stick-type cosmetics in which cosmetics with different properties are clearly arranged on the inside and outside. Furthermore, the stick-type cosmetic manufacturing apparatus 1 according to the second embodiment is equipped with a filling collar 7, which allows the cosmetic to be filled so that it exceeds the upper end of the filling section 21, in other words, the cosmetic to be overfilled. With the stick-type cosmetic manufacturing apparatus 1 according to the second embodiment, even if a depression (also known as a sink mark) occurs on the surface of the filled cosmetic due to concentrated shrinkage strain, the tip where the depression occurred can be cut off, thereby improving the quality of the manufactured cosmetic. The cut-off excess portion can be reused. Furthermore, simply connecting the filling collar 7 is sufficient to easily manufacture stick-type cosmetics. Furthermore, for example, in a back-filling method in which cosmetics are filled from the bottom of a cosmetic container, heat must be irradiated through a hole in the bottom of the container to prevent depressions from occurring, which requires the hole in the bottom of the container to be enlarged. Therefore, while the bag-filling method may be subject to restrictions on the shape of the container, the manufacturing apparatus 1 for stick-type cosmetics according to the second embodiment does not have the restrictions on the shape of the container that are present in the bag-filling method. Furthermore, the filling collar 7 has a stepped portion 71, which not only positions the filling collar 7 but also ensures a secure connection between the filling collar 7 and the filling portion 21. Furthermore, the filling collar 7 has a tapered end, which increases the opening area and makes filling easier compared to when the tip of the filling collar 7 is horizontal. As a result, productivity is improved.

[0055] <Third embodiment> <Device configuration> As shown in FIG. 15 , the manufacturing apparatus 1 for stick-type cosmetics according to the third embodiment has a container holder 5 and centering jig 6 with simpler configurations than those of the first and second embodiments. A filling collar 7 functions as the centering jig 6. Components similar to those of the manufacturing apparatus 1 for stick-type cosmetics according to the first and second embodiments are given the same reference numerals, and descriptions thereof will be omitted. The manufacturing apparatus 1 for stick-type cosmetics according to the third embodiment includes a cosmetic container 2 (an example of a filling section of the present invention), a center pipe 3 (an example of a dividing section of the present invention), a center round bar 4 (an example of a rod-shaped section of the present invention), a centering jig 6 (an example of a dividing support section of the present invention), and the filling collar 7. The container holder 5 according to the third embodiment has a container lower mold base 521 as a container lower mold 52.

[0056] The filling collar 7 is cylindrical and connected to the stick-shaped cosmetic container so as to communicate with the filling portion 21. The filling collar allows the cosmetic to be filled up to a position above the upper end of the filling portion 21. Like the filling collar 7 of the second embodiment, the filling collar 7 of the third embodiment has a stepped portion 71 (not shown) located on the inside of the lower portion and configured as a step that engages with the upper end of the filling portion 21. The filling collar 7 of the third embodiment also has a rectangular collar opening window 72 at the upper part of the side surface. The cosmetic can be filled through the collar opening window 72 and the filling status can be confirmed. A collar round bar stay 62 serving as a centering jig 6 is connected to the upper part of the filling collar 7 of the third embodiment.

[0057] The centering jig 6 according to the third embodiment includes a collar stay 62 that is connected to the top of the filling collar 7 like a lid. The collar stay 62 covers the upper opening of the filling collar 7 according to the third embodiment. The collar stay 62 has a circular collar stay through-hole 62a formed vertically near the center, through which the center pipe 3 passes. The collar stay 62 also has a threaded hole 62b on its side for a screw (not shown) that serves as a fastening member for securing the center pipe 3 from the side. The inner surface of the threaded hole 62b is threaded to mate with the screw. The screw and the threaded hole 62b allow the center of the center pipe 3 to be fixed at a height where its lower end abuts the bottom of the filling section 21. The center pipe 3 and the collar stay 62 may be integrally formed.

[0058] <Manufacturing method> Next, a method for producing a filled cosmetic material according to the third embodiment will be described, focusing on the differences from the first and second embodiments. Like the first and second embodiments, the method for producing a filled cosmetic material according to the third embodiment includes a first preparation step (S01), a first filling step (S02), a first gradual cooling step (S03), a second preparation step (S04), a second filling step (S05), a second gradual cooling step (S06), and a finishing step (S07) (see FIG. 5).

[0059] In the first preparation step (S01), the filling collar 7 is connected to the filling section 21 of the cosmetic container 2. The filling collar 7 may be connected to the filling section 21 later. Next, a collar round bar stay 62 serving as a centering jig 6 is connected to the top of the filling collar 7, and the center pipe 3 and the center round bar 4 are set in place.

[0060] In the first filling step (S02), the cosmetic material (outside) is filled. More specifically, the cosmetic material is filled onto the outside of the central pipe 3 in the filling section 21 through the collar opening window 72. Because the filling collar 7 is connected to the filling section 21, the cosmetic material is filled so that it exceeds the upper end of the filling section 21. The filling status can be confirmed through the collar opening window 72.

[0061] In the first slow cooling step (S03), the cosmetic material filled on the outside is slowly cooled. In the second preparation step (S04), the center round rod 4 is removed from the center pipe 3, the center pipe 3 is removed from the filling section 21 of the cosmetic container 2, and the collar round rod stay 62 serving as the centering jig 6 is removed from the filling collar 7.

[0062] In the second filling step (S05), the cosmetic (center portion) is filled. More specifically, the cosmetic is filled into the inside of the filling section 21 (the area from which the center pipe 3 has been removed) through the collar opening window 72. Furthermore, because the filling collar 7 is connected to the filling section 21, the cosmetic is filled so that it exceeds the upper end of the filling section 21. The filling state can be confirmed through the collar opening window 72.

[0063] In the second gradual cooling step (S06), the cosmetic material filled in the center is slowly cooled. The gradual cooling time and the temperature after gradual cooling are determined appropriately depending on the cosmetic material to be filled. In the second gradual cooling step, forced cooling may be performed, where necessary, at a temperature lower than that of gradual cooling so that the cosmetic material is solidified.

[0064] In the finishing step (S07), finishing is carried out. Unlike the first embodiment, the filling collar 7 is separated from the filling portion 21. Next, the tip of the stick-shaped cosmetic material is cut. Examples of cutting methods include cutting with a wire or a knife. Next, the top surface of the filled cosmetic material is shaped, in other words, the top surface is finished. Once shaping of the top surface of the cosmetic material is complete, the cosmetic material container 2 is removed from the container holder 5, and the production of the cosmetic material is completed (see FIG. 9).

[0065] The stick-type cosmetic manufacturing apparatus 1 according to the third embodiment has a simpler configuration than the first and second embodiments, but can achieve the same effects as the stick-type cosmetic manufacturing apparatus 1 according to the first and second embodiments. That is, it is possible to manufacture a stick-type cosmetic in which cosmetics with different properties are clearly arranged on the inside and outside. Furthermore, the stick-type cosmetic manufacturing apparatus 1 according to the third embodiment is equipped with a filling collar 7, which allows the cosmetic to be filled so that it exceeds the upper end of the filling section 21, in other words, the cosmetic to be overfilled. With the stick-type cosmetic manufacturing apparatus 1 according to the third embodiment, even if a depression (also known as a sink mark) occurs on the surface of the filled cosmetic due to concentrated shrinkage strain, the tip where the depression occurred can be cut off, thereby improving the quality of the manufactured cosmetic. Furthermore, the stepped portion 71 of the filling collar 7 positions the filling collar 7 and ensures a secure connection between the filling collar 7 and the filling section 21. Furthermore, the tapered end of the filling collar 7 increases the opening area compared to when the tip of the filling collar is horizontal, making filling easier. As a result, productivity is improved. The filling collar 7 according to the third embodiment has a rectangular collar opening window 72 on its side, through which the cosmetic can be filled and the filling status can be checked. The centering jig 6 according to the third embodiment is made up of a collar round rod stay 62 that is connected to the top of the filling collar 7 like a lid, and has a very simple configuration. The collar round rod stay 62 has a screw hole 62b on its side, and the center pipe 3 can be fixed by inserting a screw into the screw hole 62b.

[0066] <Fourth embodiment> As shown in Fig. 16, the manufacturing apparatus 1 for stick-type cosmetics according to the fourth embodiment has a configuration similar to that of the third embodiment. The manufacturing apparatus 1 for stick-type cosmetics according to the fourth embodiment further includes an internal jig 8 (an example of an internal jig of the present invention) and a jig fixing unit 9 (an example of a jig fixing unit of the present invention). The same components as those in the manufacturing apparatus 1 for stick-type cosmetics according to the first to third embodiments are designated by the same reference numerals, and a description thereof will be omitted. The manufacturing apparatus 1 for stick-type cosmetics according to the fourth embodiment includes a cosmetic container 2 (an example of a filling unit of the present invention), an internal jig (an example of an internal jig of the present invention), a jig fixing unit (an example of a jig fixing unit of the present invention), a center pipe 3 (an example of a dividing unit of the present invention), a central round bar 4 (an example of a rod-shaped unit of the present invention), a container holder 5 (an example of a container support unit of the present invention), a centering jig 6 (an example of a dividing support unit of the present invention), and a filling collar 7.

[0067] The internal jig 8 suppresses the filling of the cosmetic material by filling a portion of the interior of the filling section 21 so that the boundary is linear. The internal jig 8 is composed of a columnar member that is semicircular in cross section so that it fills half of the interior of the circular filling section 21. The internal jig 8 is composed of a ferromagnetic material (iron in this embodiment). The internal jig 8 may be configured to cut longitudinally or transversely through the interior of the filling section 21, in other words, to linearly divide the interior of the filling section 21 from one inner wall to the other. The internal jig 8 in this embodiment linearly divides the interior of the filling section 21 into two sections, but may also divide it into a curved section. The internal jig 8 may also divide the interior of the filling section 21 into multiple sections, for example, into three parallel sections or three radial sections.

[0068] The jig fixing portion 9 fixes the position of the internal jig 8. The jig fixing portion 9 according to the fourth embodiment is made of a magnet and attracts (sticks to) the internal jig 8, which is made of a ferromagnetic material, thereby fixing the position of the internal jig 8. In this embodiment, the jig fixing portion 9 contacts the outer surface of the filling portion 21 and attracts (sticks to) the internal jig 8 so as to sandwich the filling portion 21. The jig fixing portion 9 may contact the outer surface of the filling collar 7 and be attracted to the internal jig 8 so as to sandwich the filling collar 7 and the filling portion 21. By contacting the outer surface of the filling portion 21 and being attracted to the internal jig 8 so as to sandwich the filling portion 21, the position of the internal jig 8 can be fixed more stably. The jig fixing portion 9 may be, for example, a device (e.g., a clip) that sandwiches and fixes the internal jig 8 and the filling portion 21. The jig fixing portion 9 may also be a hook or the like that is hooked onto the upper end of the filling portion 21.

[0069] The container lower mold 52 is composed of a container lower mold base 521 made of a plate-like member. The container lower mold base 521 is provided with a circular recess 521a that accommodates the lower part of the cosmetic container 2. The recess 521a of the container lower mold base 521 according to the fourth embodiment is configured to support the cosmetic container 2 vertically. The recess 521a may also be configured to support the cosmetic container 2 at an angle.

[0070] The filling collar 7 according to the fourth embodiment is provided with a collar opening window 72, similar to the filling collar 7 according to the third embodiment. Cosmetic material can be filled through this collar opening window 72, and the filling status can also be checked. The centering jig 6 according to the fourth embodiment is made up of a collar round rod stay 62 that is connected to the top of the filling collar 7 like a lid, and has a very simple configuration. The collar round rod stay 62 has a screw hole 62b on its side, and the center pipe 3 can be fixed by inserting a screw into the screw hole 62b.

[0071] The centering jig 6 according to the fourth embodiment, like the third embodiment, has a collar round rod stay 62 that is connected like a lid to the top of the filling collar 7. The collar round rod stay 62 according to the fourth embodiment has a circular collar round rod stay through-hole 62a, through which the center pipe 3 passes, at an eccentric position. More specifically, the collar round rod stay 62 according to the fourth embodiment has a circular collar round rod stay through-hole 62a, through which the center pipe 3 passes, near the center of a portion (semicircular in this embodiment) of the filling section 21 other than the portion filled by the internal jig 8. Description of the cosmetic container 2, center pipe 3, and center round rod 4 will be omitted.

[0072] <Manufacturing method> Next, the method for producing a filled cosmetic material according to the fourth embodiment will be described, focusing on the differences from the first to third embodiments. Like the first to third embodiments, the method for producing a filled cosmetic material according to the fourth embodiment includes a first preparation step (S01), a first filling step (S02), a first gradual cooling step (S03), a second preparation step (S04), a second filling step (S05), a second gradual cooling step (S06), and a finishing step (S07) (see FIG. 5).

[0073] In the first preparation step (S01), the internal jig 8 is fixed to the filling collar 7 using a jig fixing part 9 made of a magnet (see Figures 16 and 17). Next, the filling collar 7 with the internal jig 8 fixed thereto is connected to the cosmetic container 2. The filling collar 7 may be connected to the filling part 21 later. Next, the cosmetic container 2 is set in the recess 521a of the container lower mold 52 of the container holder 5. Next, a collar round bar stay 62 serving as the centering jig 6 is connected to the top of the filling collar 7, and the center pipe 3 and center round bar 4 are set.

[0074] In the first filling step (S02), the cosmetic is filled (see FIG. 18). In the fourth embodiment, an internal jig 8 is fixed to the filling section 21, and the cosmetic is filled in the area where the internal jig 8 is not disposed and in the area other than the central pipe 3. The cosmetic is filled while the filling state is being checked through the collar opening window 72.

[0075] In the first slow cooling step (S03), the filled cosmetic material is slowly cooled. In the second preparation step (S04), the center round rod 4 is removed from the center pipe 3, the center pipe 3 is removed from the filling section 21 of the cosmetic container 2, the collar round rod stay 62 serving as the centering jig 6 is removed from the filling collar 7, and the internal jig 8 is removed.

[0076] In the second filling step (S05), the cosmetic is filled (see FIG. 19). In the fourth embodiment, the cosmetic is filled into the area where the internal jig 8 was fixed and the area where the central pipe 3 was disposed. The cosmetic is filled while the filling state is being checked through the collar opening window 72.

[0077] In the second gradual cooling step (S06), the filled cosmetic material is slowly cooled. The gradual cooling time and the temperature after gradual cooling are determined appropriately depending on the cosmetic material to be filled. In the second gradual cooling step, forced cooling may be performed at a temperature lower than that of gradual cooling, as necessary, so that the cosmetic material is solidified.

[0078] In the finishing step (S07), finishing is carried out. First, the filling collar 7 is separated from the filling portion 21. Next, the tip of the stick-shaped cosmetic material is cut. Examples of cutting methods include cutting with a wire or a knife. Next, the top surface of the filled cosmetic material is shaped, in other words, the top surface is finished. Once the shaping of the top surface of the cosmetic material is complete, the cosmetic material container 2 is removed from the container holder 5, and the production of the cosmetic material is completed (see FIG. 19).

[0079] The stick-type cosmetic manufacturing apparatus 1 according to the fourth embodiment includes an internal jig 8 and a jig fixing unit 9 in addition to the configuration of the stick-type cosmetic manufacturing apparatus 1 according to the third embodiment. This allows the manufacturing of stick-type cosmetics that are linearly divided into left and right (or top and bottom) regions, and in which cosmetics with different properties are clearly arranged on the inside and outside in one of the left and right regions. The division into left and right regions can be achieved simply by placing the internal jig 8 in the filling section 21 and fixing it with the jig fixing unit 9, which is made of a magnet. Furthermore, the inclusion of a filling collar 7 in the stick-type cosmetic manufacturing apparatus 1 according to the fourth embodiment allows so-called overfilling. Furthermore, by enabling overfilling, even if a depression (also known as a sink mark) occurs on the surface of the filled cosmetic due to concentrated shrinkage distortion, the tip where the depression occurred can be cut off, thereby improving the quality of the manufactured cosmetic. Furthermore, the filling collar 7 has a stepped portion 71, which positions the filling collar 7 and ensures a secure connection between the filling collar 7 and the filling section 21. The centering jig 6 according to the fourth embodiment has a very simple configuration, consisting of a collar round rod stay 62 that is connected like a lid to the top of the filling collar 7. The collar round rod stay 62 has a screw hole 62b on its side, and the center pipe 3 can be fixed in place by inserting a screw into the screw hole 62b.

[0080] Although the embodiments of the present invention have been described above, the apparatus for manufacturing a stick-type cosmetic product and the method for manufacturing a stick-type cosmetic product according to the present invention are not limited to these, and these can be combined as much as possible. Furthermore, the present invention can be modified as appropriate without departing from the gist of the present invention.

[0081] In the embodiment, the cosmetic material is directly filled into the cosmetic material container 2, but the cosmetic material may also be filled into a mold. That is, the filling section may be configured as a mold section. By using a mold section as the filling section, the manufacturing apparatus for stick-type cosmetic materials can be used as a manufacturing apparatus that molds stick-type cosmetic materials using a mold. The mold section can be configured, for example, from multiple parts. Providing multiple parts increases the degree of freedom in designing the stick-type cosmetic material.

[0082] The filling section may also consist of a resin mold section made of resin into which the cosmetic material is filled. By using a resin molding section as the filling section, the manufacturing device for stick-type cosmetics can be used as a manufacturing device for resin / rubber mold filling, in which the cosmetic material is filled into a resin or rubber mold or ogive. The resin mold section can be composed of, for example, multiple parts. Providing multiple parts increases the degree of freedom in designing the stick-type cosmetic material.
