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] Stick-type cosmetics have been available for some time. Conventional methods for producing stick-type cosmetics include, for example, a technique of directly filling a stick-type container and molding it. For example, Patent Document 1 discloses a stick-type cosmetic container that employs a so-called back-filling method in which a cosmetic that has been heated and melted is directly filled into the container from the bottom 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] One known method for manufacturing stick-type cosmetics is the so-called bag-filling method, in which a heated and melted cosmetic is filled directly 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 complicates 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.

[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 can produce a stick-type cosmetic product with a uniform crystal structure by a method that is simpler than conventional methods. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention provides the following means: That is, the present invention provides an apparatus for manufacturing a stick-shaped cosmetic product, the apparatus comprising: a filling section that is part of a cosmetic container and into which a cosmetic product is filled; and a tubular filling collar that is connected to the stick-shaped cosmetic container so as to communicate with the filling section.

[0007] The manufacturing apparatus for stick-type cosmetics according to the present invention can be suitably used as a manufacturing apparatus for directly filling cosmetics into cosmetic containers. The manufacturing apparatus for stick-type cosmetics according to the present invention is provided with a filling collar, which allows the cosmetics to be filled so that they exceed the upper end of the filling section, in other words, the cosmetics to be overfilled. With the manufacturing apparatus for stick-type cosmetics according to the present invention, even if a depression (also called 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 cosmetics. The cut-off excess portion can be reused. Furthermore, stick-type cosmetics can be easily manufactured simply by connecting the filling collar. Furthermore, unlike the bag-filling method, there are no restrictions on the shape of the cosmetic container. Cosmetics include lipstick, lip balm, etc. Examples of containers for stick-type cosmetics include lipstick cosmetic containers and lip balm cosmetic containers.

[0008] Here, in the manufacturing device for stick-type cosmetics according to the present invention, the filling collar may be provided on the inside and have a stepped portion that is a step that engages with the upper end of the filling portion.

[0009] The filling collar has a step portion, which not only positions the filling collar but also ensures a secure connection between the filling collar and the filling portion.

[0010] The filling collar may also have a tapered end, where the top end is notched at an angle. The tapered end of the filling collar increases the opening area and facilitates filling compared to a filling collar with a horizontal tip. This improves productivity.

[0011] In addition, the manufacturing apparatus for stick-shaped cosmetics according to the present invention may further include a dividing section that divides the inside of the filling section, and the dividing section may have an internal jig that suppresses the filling of the cosmetic by filling part of the inside of the filling section so as to run vertically or transversely through the inside of the filling section.

[0012] According to the manufacturing device for stick-type cosmetics of the present invention, the interior of the filling section can be divided by providing a dividing section. By providing an internal jig, cosmetics can be filled into areas of the interior of the filling section other than those into which the internal jig is inserted. Cutting the interior of the filling section vertically or transversely means dividing the interior of the filling section linearly from one internal wall to the other. The linear division may be either straight or curved. After filling with cosmetics, the internal jig is removed and cosmetics of different properties are filled, thereby producing a stick-type cosmetic in which cosmetics of different properties are clearly separated and arranged vertically or transversely within the interior of the filling section. Examples of cosmetics of different properties include cosmetics of different colors and cosmetics with different ingredients. The manufacturing device 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 produce a stick-type cosmetic in which cosmetics of different properties are clearly separated and arranged along a linear boundary.

[0013] 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.

[0014] Here, the manufacturing device for stick-type cosmetics according to the present invention may further include a container support part that supports the cosmetic container, and a division support part that is connected to the container support part and supports the division part.

[0015] The container support portion allows the rod-shaped cosmetic container to be stably supported, and the divided support portion allows the divided portion to be stably supported.

[0016] In the manufacturing device for stick-type cosmetic material according to the present invention, the container support part may be configured to support the cosmetic container so that the tapered end is horizontal. In other words, the container support part may be configured to support the cosmetic container with the main body inclined and the tapered end being horizontal. This makes it easier to fill the cosmetic material and cut the end of the stick-type cosmetic material.

[0017] In addition, the manufacturing apparatus for stick-shaped cosmetics according to the present invention may further include a dividing section that is provided inside the filling section and divides the inside of the filling section when the cosmetic is filled, and the dividing section may be cylindrical and divide the inside of the filling section into an inside and an outside.

[0018] According to the manufacturing device 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. Examples of cosmetics of different properties include cosmetics with different colors and cosmetics with different ingredients. The manufacturing device 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.

[0019] The apparatus for manufacturing a stick-type cosmetic product according to the present invention may further include a dividing section disposed inside the filling section and dividing the interior of the filling section when the cosmetic product is being filled, and the dividing section may further include a rod-shaped section inserted therein. Here, there is a concern that the cosmetic product may be filled into the divided section when filling the cosmetic product. However, by filling the cosmetic product with the rod-shaped section inserted inside the divided section, the cosmetic product can be filled into areas of the filling section other than those into which the divided section and rod-shaped section are inserted. After filling the cosmetic product, the dividing section and rod-shaped section are removed, and then cosmetic products of different properties are filled. This makes it possible to produce a stick-shaped cosmetic product in which cosmetic products 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 cylindrical dividing section. 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. in the cosmetic product filled on the outside, particularly at the tip. Such cosmetic defects caused by 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, making cosmetic defects less likely to occur due to back pressure. Furthermore, by inserting a rod-shaped section inside the divided section, it is possible to prevent the cosmetic from filling, or in other words, flowing, into the divided section as described above. As described above, a rod-shaped cosmetic can be produced 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 inside of 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 inside of the cylindrical divided section.

[0020] In the cosmetic manufacturing device according to the present invention, the tip of the dividing section may be tapered.

[0021] 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. It also allows air to escape more easily, preventing air from accumulating at the tip of the dividing section. As a result, the quality of the produced cosmetic product can be improved, and the boundary of the cosmetic product can be more clearly distinguished.

[0022] 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 filling collar is connected to the stick-shaped cosmetic container so as to communicate with the filling portion and the cosmetic product is filled into the filling collar.

[0023] According to the method for producing a stick-type cosmetic product of the present invention, by using a filling collar to fill the filling section with the cosmetic product, it is possible to fill the cosmetic product so that it exceeds the upper end of the filling section, in other words, to overfill the cosmetic product. According to the method for producing a stick-type cosmetic product of the present invention, even if a depression (also called a sink mark) occurs on the surface of the filled cosmetic product due to concentrated shrinkage distortion, the tip where the depression occurred can be cut off, thereby improving the quality of the produced cosmetic product. The cut-off excess portion can be reused. Furthermore, by simply connecting the filling collar, stick-type cosmetic products can be easily produced. Furthermore, there are no restrictions on the shape of the cosmetic container, as is the case with the bag-filling method. [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 that can produce a stick-type cosmetic product with a uniform crystal structure using a method that is simpler than conventional methods.

[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> The manufacturing apparatus 1 for stick-type cosmetics according to the first embodiment comprises a cosmetic container 2 (an example of a main body of the present invention), a container holder 5 (an example of a container support part of the present invention), and a filling collar 7 (an example of a filling collar of the present invention) (see Figures 1 to 3).

[0028] The cosmetic container 2 (an example of the main body 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 tip of the filling section 21 is notched in a tapered shape. The filling section 21 may also have a horizontal shape with a notched tip. 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 container holder 5 includes a container lower mold base 521 as the container lower mold 52, container lower mold columns 522 rising from both ends of the container lower mold base 521, and a container support portion 523 that is parallel to the container lower mold base 521 and is connected to the upper ends of the container lower mold columns 522 to support the cosmetic container 2. The container lower mold 52 is composed of the container lower mold base 521 made of a plate-like member. The container lower mold base 521 is provided with a plurality of circular depressions 521a that accommodate the lower portions of the cosmetic container 2. The depressions 521a of the container lower mold base 521 according to the first embodiment are configured to support the cosmetic container 2 vertically. The depressions 521a may also be configured to support the cosmetic container 2 at an angle. The depressions 521a may be replaced with through-holes.

[0030] 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 cut upper end.

[0031] <Manufacturing method> Next, a method for producing a filled cosmetic material according to the first embodiment will be described. Fig. 4 shows a flow diagram of the method for producing a filled cosmetic material according to the first embodiment. The method for producing a filled cosmetic material according to the first embodiment includes a first preparation step (S01), a first filling step (S02), a first gradual cooling step (S03), and a finishing step (S07).

[0032] In the first preparation step (S01), in preparation for the first filling step, 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, the cosmetic container 2 is set in the container holder 5 (container lower mold 52). More specifically, the lower part of the cosmetic container 2 is inserted into the recess 521a of the base 521 of the container lower mold.

[0033] In the first filling step (S02), the cosmetic is filled in. Since the filling collar 7 is connected to the filling portion 21, the cosmetic is filled in so that it exceeds the upper end of the filling portion 21 (see FIG. 5).

[0034] In the first gradual cooling step (S03), 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. After the first gradual cooling step (S03) is completed, the process proceeds to the finishing step (S07).

[0035] In the finishing step (S07), finishing is carried out. More specifically, 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, 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. 6).

[0036] The manufacturing apparatus 1 for stick-type cosmetics according to the first embodiment includes 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. According to the manufacturing apparatus 1 for stick-type cosmetics according to the first embodiment, even if a depression (also called 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, simply connecting the filling collar 7 allows for easy manufacturing of stick-type cosmetics. Furthermore, for example, in a bag-filling method in which the cosmetic is filled from the bottom of a cosmetic container, 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 manufacturing apparatus 1 for stick-type cosmetics according to the first embodiment does not have the same restrictions on the shape of the container as the bag-filling method. 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 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.

[0037] Second Embodiment <Device configuration> The manufacturing apparatus 1 for stick-type cosmetics according to the second embodiment includes a cosmetic container 2 (an example of a main body of the present invention), an internal jig 8 (an example of an internal jig of the present invention), a jig fixing part 9 (an example of a jig fixing part of the present invention), a container holder 5 (an example of a container support part of the present invention), and a filling collar 7. Components similar to those in the first embodiment are given the same reference numerals, and descriptions thereof will be omitted.

[0038] 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.

[0039] The jig fixing portion 9 fixes the position of the internal jig 8. The jig fixing portion 9 according to the second 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.

[0040] The filling collar 7 and the container holder 5 are the same as those in the first embodiment, and therefore a description thereof will be omitted.

[0041] <Manufacturing method> 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. 9).

[0042] 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. 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 (see FIGS. 7 and 8).

[0043] In the first filling step (S02), the cosmetic material is filled (see FIG. 10). In the second embodiment, an internal jig 8 is fixed to the filling section 21, and the cosmetic material is filled in the area where the internal jig 8 is not arranged.

[0044] In the first slow cooling step (S03), the filled cosmetic material is slowly cooled. In the second preparation step (S04), the internal jig 8 is removed.

[0045] In the second filling step (S05), the cosmetic material is filled (see FIG. 11). In the second embodiment, the cosmetic material is filled into the area where the internal jig 8 was fixed.

[0046] 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.

[0047] 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. 6).

[0048] The stick-type cosmetic manufacturing apparatus 1 according to the second 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 first embodiment. This allows the manufacturing of stick-type cosmetics that are linearly divided into left and right (or top and bottom) regions, and in one of the left and right regions, cosmetics with different properties are clearly arranged on the inside and outside. 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 stick-type cosmetic manufacturing apparatus 1 according to the second embodiment includes a filling collar 7, which allows so-called overfilling. Furthermore, by allowing 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 step 71, which positions the filling collar 7 and ensures a secure connection between the filling collar 7 and the filling section 21.

[0049] <Third embodiment> <Device configuration> The manufacturing apparatus 1 for stick-type cosmetics according to the third embodiment comprises a cosmetic container 2 (an example of the main body of the present invention), a central pipe 3 (an example of the dividing portion of the present invention), a central round bar 4 (an example of the rod-shaped portion of the present invention), a container holder 5 (an example of the container support portion of the present invention), a centering jig 6 (an example of the divided support portion of the present invention), and a filling collar 7 (see Figures 12 to 19).

[0050] 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 rod 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, preventing air from accumulating at the tip of the center pipe 3.

[0051] 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.

[0052] 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 has a container lower mold 52 that supports the lower portions of the cosmetic containers 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 portions of the cosmetic containers 2. The container holder 5 may further include a container upper mold 51 that supports the upper portions of the cosmetic containers 2. In this case, the container upper mold 51 can be connected to the upper portions of the container lower mold columns 522 parallel to the container lower mold base 521. The container upper mold 51 may also be provided with a circular upper mold through-hole 51a through which the upper portion of the cosmetic container 2 passes. A plurality of through holes 51a of the upper mold can be provided at positions corresponding to the recesses of the base 521 of the container lower mold. A recess may be provided instead of the through holes 51a. The recesses of the base 521 of the container lower mold may be provided as through holes, and the top surface of the table on which the container holder 5 is placed may support the lower part of the cosmetic container 2. Furthermore, although the container holder 5 of this embodiment supports a plurality of cosmetic containers 2, it may also support a single cosmetic container 2.

[0053] The centering jig 6 is connected to the top of the container holder 5 and supports the center pipe 3. The centering jig 6 is parallel to the base 521 of the container lower mold and has a center round stay 61 composed of a plate-like member connected to the top of the columns 522 of the container lower mold. The center round stay 61 has multiple circular 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. When the container upper mold 51 is provided, the centering jig 6 can be configured to further include a stand stay 62. The stand stay 62 can be composed of a column located on an extension of the columns 522 of the container lower mold. In this case, the center round stay 61 is parallel to the base 521 of the container lower mold and can be connected to the top of the stand stay 62.

[0054] 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 cut-out upper end that is cut out at the same angle as the tapered shape of the tip of the filling portion 21.

[0055] <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 second embodiment, 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. 9).

[0056] 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.

[0057] In the first filling step (S02), the cosmetic material (outside) is filled (see FIG. 17). 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.

[0058] 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.

[0059] In the second filling step (S05), the cosmetic (center portion) is filled (see FIG. 18). 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.

[0060] 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.

[0061] 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).

[0062] The manufacturing apparatus 1 for stick-type cosmetics according to the third embodiment can produce stick-type cosmetics in which cosmetics with different properties are clearly arranged on the inside and outside. Furthermore, the manufacturing apparatus 1 for stick-type cosmetics according to the third embodiment is equipped with a filling collar 7, which allows the cosmetics to be filled so that they exceed the upper end of the filling section 21, in other words, the cosmetics can be overfilled. As a result, even if a depression (also known as a sink mark) occurs on the surface of the filled cosmetics due to concentrated shrinkage strain, the tip where the depression occurred can be cut off, improving the quality of the produced cosmetics. The cut-off excess portion can be reused. Furthermore, simply connecting the filling collar 7 allows for easy production of 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 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 large. 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 third 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 tapered end of the filling collar 7 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.

[0063] It is also possible to use a rod-shaped member instead of the center pipe 3, but 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.

[0064] 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.

[0065] <Fourth embodiment> <Device configuration> The manufacturing apparatus 1 for stick-type cosmetics according to the fourth embodiment comprises a cosmetic container 2 (an example of the main body of the present invention), a center pipe 3 (an example of the dividing portion of the present invention), a center round bar 4 (an example of the rod-shaped portion of the present invention), a centering jig 6 (an example of the dividing support portion of the present invention), a container holder 5, and a filling collar 7 (see FIG. 20). The center pipe 3 and center round bar 4 are the same as those in the third embodiment, and therefore a description thereof will be omitted.

[0066] The filling collar 7 is cylindrical and connected to the stick-shaped cosmetic container so as to communicate with the filling section 21. The filling collar allows the cosmetic to be filled up to a position above the upper end of the filling section 21. Like the filling collar 7 of the third embodiment, the filling collar 7 of the fourth embodiment has a stepped portion 71 formed on the inside of the lower part and configured as a step that engages with the upper end of the filling section 21. The filling collar 7 of the fourth 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.

[0067] The centering jig 6 according to the fourth embodiment has 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 fourth 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.

[0068] <Manufacturing method> The method for producing a filled cosmetic material according to the fourth embodiment, like the second and third embodiments, 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. 9).

[0069] 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.

[0070] In the first filling step (S02), the cosmetic material (outside) is filled. More specifically, the cosmetic material is filled through the collar opening window 72. Because the filling collar 7 is connected to the filling portion 21, the cosmetic material is filled so that it exceeds the upper end of the filling portion 21. The filling state can be confirmed through the collar opening window 72.

[0071] 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.

[0072] In the second filling step (S05), the cosmetic (center portion) is filled. As in the first filling step, the cosmetic is filled through the collar opening window 72. Furthermore, because the filling collar 7 is connected to the filling portion 21, the cosmetic is filled so that it exceeds the upper end of the filling portion 21. The filling state can be confirmed through the collar opening window 72.

[0073] 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.

[0074] 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).

[0075] The stick-type cosmetic manufacturing apparatus 1 according to the fourth embodiment can produce a stick-type cosmetic product in which different cosmetic properties are clearly distinguished between the inside and outside. Furthermore, the stick-type cosmetic manufacturing apparatus 1 according to the fourth embodiment includes a filling collar 7, which allows the cosmetic product to be filled so that it exceeds the upper end of the filling section 21, in other words, overfilling the cosmetic product. As a result, even if a depression (also known as a sink mark) occurs on the surface of the filled cosmetic product due to concentrated shrinkage strain, the tip where the depression occurred can be cut off, improving the quality of the produced cosmetic product. 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. Furthermore, the filling collar 7 has a tapered end, which 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 fourth embodiment has a rectangular collar opening window 72 on its side, through which the cosmetic product can be filled and the filling status can be confirmed. The centering jig 6 according to the third 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.

[0076] Fifth Embodiment The manufacturing apparatus 1 for stick-type cosmetics according to the fifth embodiment comprises a cosmetic container 2 (an example of a main body portion of the present invention), an internal jig (an example of an internal jig of the present invention), a jig fixing portion (an example of a jig fixing portion of the present invention), a center pipe 3 (an example of a dividing portion of the present invention), a central round bar 4 (an example of a rod-shaped portion of the present invention), a container holder 5 (an example of a container support portion of the present invention), a centering jig 6 (an example of a dividing support portion of the present invention), and a filling collar 7. The manufacturing apparatus 1 for stick-type cosmetics according to the fifth embodiment has a configuration that combines the second and fourth embodiments.

[0077] 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.

[0078] The jig fixing portion 9 fixes the position of the internal jig 8. The jig fixing portion 9 according to the fifth 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.

[0079] 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.

[0080] The filling collar 7 according to the fifth embodiment is provided with a collar opening window 72. 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.

[0081] The centering jig 6 according to the fifth 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.

[0082] <Manufacturing method> The method for producing a filled cosmetic material according to the fifth 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. 9).

[0083] 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 21 and 22). 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.

[0084] In the first filling step (S02), the cosmetic is filled (see FIG. 23). In the fifth 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.

[0085] 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.

[0086] In the second filling step (S05), the cosmetic is filled (see FIG. 24). 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.

[0087] 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.

[0088] 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 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. 24).

[0089] The stick-type cosmetic manufacturing apparatus 1 according to the fifth 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 manufacture of stick-type cosmetics that are linearly divided into left and right (or top and bottom) regions, with cosmetics of different properties 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 stick-type cosmetic manufacturing apparatus 1 according to the fifth embodiment includes a filling collar 7, allowing 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.

[0090] Although the embodiments of the present invention have been described above, the apparatus for manufacturing stick-type cosmetics according to the present invention is 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.

[0091] FIG. 25 shows a side view of a stick-type cosmetic manufacturing device according to a modified example of the second embodiment. The stick-type cosmetic manufacturing device 1 according to the modified example of the second embodiment has a simpler configuration than the stick-type cosmetic device 1 according to the second embodiment, omitting the filling collar 7. In a first preparation step (S01), an internal jig 8 is fixed in the filling section 21 by a jig fixing part 9. Next, in a first filling step (S02), the cosmetic is filled into the area where the internal jig 8 is not located, and in a first gradual cooling step (S03), the filled cosmetic is gradual cooled. In a second preparation step (S04), the internal jig 8 and jig fixing part 9 are removed, and in a second filling step (S05), the cosmetic is filled into the area where the internal jig 8 was fixed. In a second gradual cooling step (S06), the filled cosmetic is gradual cooled, and finishing is performed in a finishing step (S07), completing the production of the cosmetic.
