Description

Technical Field

[0001] This invention relates to a cosmetic forming apparatus and a method for forming rod-shaped cosmetics within the cosmetic forming apparatus. Background Technology

[0002] In the traditional manufacturing process of stick cosmetics such as lipsticks and eyeliners, such as Figure 1 As shown, the material is heated and melted (preheated), and the cosmetic composition flows into the molding die. After being cooled and solidified using cold air, it is detached from the molding die to form the desired shape. Furthermore, during the cooling and solidification process, by applying upper heating (reheating) based on warm air and a gradual cooling process based on maintaining room temperature, deformations such as shrinkage pores that occur during the cooling and solidification process of the cosmetic composition are eliminated.

[0003] In this case, if cold air is blown from below and warm air is blown from above in a molding die filled with cosmetic material, the top (bottom) part of the die will be rapidly cooled, while the base (top) part will be gradually cooled. Therefore, the blowing method of the warm and cold air needs to be adjusted to avoid uneven temperature distribution. In this adjustment, the range of molding conditions is narrow to avoid uneven appearance or insufficient strength after curing.

[0004] Furthermore, since it is also affected by external environmental factors such as ambient temperature and humidity, conveying speed, and the number of products flowing in the production line, skilled techniques are required when setting molding conditions in order to consistently produce high-quality products. In particular, the following problems have arisen: during testing, because experiments are conducted with a small production quantity, it is easy to cool down, while during mass production, due to the large quantity, it is difficult to cool down compared to the testing phase.

[0005] Therefore, Patent Document 1 discloses a manufacturing apparatus that uses a Peltier element to control temperature, enabling high-precision forming by flexibly controlling the temperature of the metal mold even without skilled personnel. Figure 2 As shown, the manufacturing apparatus of Patent Document 1 has a plurality of filling holes X2 (X2-1 to X2-5) arranged in the longitudinal direction relative to a metal mold X1, and two Peltier elements X3 are provided on both sides in the longitudinal direction to clamp the metal mold X1.

[0008] Patent Document 1: Japanese Patent Application Publication No. 2006-158513 Summary of the Invention

[0009] The problem that the invention aims to solve

[0010] However, in the manufacturing apparatus of Patent Document 1, a temperature difference arises in each filling hole X2 on the side closest to the Peltier element X3 and the side adjacent to the adjacent filling hole X2. Furthermore, due to the heat transfer properties of the metal mold X1, the temperatures of the filling holes X2-1 and X2-5 at both ends along the length direction may be lower than those of the other central filling holes X2-2, X2-3, and X2-4, which are affected by adjacent filling holes. In other words, uniform temperature adjustment is not achieved within a single metal mold and between multiple metal molds.

[0011] Therefore, in view of the above circumstances, the present invention aims to provide a cosmetic forming apparatus capable of independently controlling the temperature of a forming mold for filling cosmetic materials, and capable of suppressing temperature unevenness in multiple forming molds and within a single forming mold regardless of the number of cosmetic products being formed.

[0012] Methods for solving problems

[0013] To solve the above-mentioned problems, a cosmetic forming apparatus according to one aspect of the present invention includes:

[0014] A cosmetic composition comprising multiple bottomed cylindrical molding dies for filling the concave portion of the cylindrical cavity with rod-shaped cosmetics.

[0015] The outer cylinder surrounds the sides of each of the plurality of forming molds from the outside;

[0016] Multiple Peltier elements are capable of heating or cooling the multiple forming molds; and

[0017] The control unit adjusts the temperature of each of the plurality of forming molds by controlling each of the plurality of Peltier elements.

[0018] The outer cylinder is configured in such a way that the multiple forming molds do not affect the temperature of the filling material.

[0019] Invention Effects

[0020] According to one approach, in a cosmetic forming apparatus, the temperature of the forming mold for filling the cosmetic composition can be independently controlled, and temperature unevenness within multiple forming molds and within a single forming mold can be suppressed regardless of the number of cosmetics being formed.

[0092] Hereinafter, the embodiments for carrying out the present invention will be described with reference to the accompanying drawings. In the following drawings, the same reference numerals will be used to label the same components, and repeated descriptions will sometimes be omitted.

[0093] This invention relates to a cosmetic forming apparatus and a method for manufacturing rod-shaped cosmetics within the cosmetic forming apparatus.

[0094] Stick cosmetics can include, for example, lipsticks, lip balms, concealers, stick eyeshadows, stick foundations, stick serums, stick moisturizers, and other oily solid substances.

[0095] In addition to being solids formed into a predetermined shape, stick cosmetics can also include compositions with a certain viscosity or higher that can maintain the predetermined shape, such as viscoelastic compositions. Below, as an example of a stick cosmetic, a lipstick will be described.

[0096] <First Implementation>

[0097] Figures 3A-3E This is an explanatory diagram of the forming process of a stick-shaped cosmetic based on the back filling method of the present invention. Figure 3A This illustrates the preheating state during the molding process of the present invention. Figure 3B Shows the state when filled. Figure 3C The diagram illustrates the reheating state based on a Peltier element. Figure 3D Indicates the cooling status. Figure 3E The image shows the detachment state during the forming process of a stick-shaped cosmetic based on the back filling method of the present invention.

[0098] like Figures 3A-3E As shown, a forming mold 1 including a rubber mold 11 and a metal mold 12, an outer cylinder 2, and a Peltier element 3 are provided near the cosmetic molded object L in the lipstick forming apparatus of the present invention.

[0099] The forming mold 1 is a bottomed cylindrical shape, and the concave part of the cylindrical shape is filled with a cosmetic composition of a rod-shaped cosmetic.

[0100] The outer cylinder 2 surrounds the sides of the forming mold 1 from the outside. The Peltier element 3 can heat or cool the forming mold 1 by temperature changes.

[0101] In addition, in the case of back filling, the molding is performed with the lifting cylinder (middle vessel cylinder) 83 and the spiral cylinder (discharge cylinder, sleeve) 82 embedded on the upper side of the cosmetic molding L.

[0102] In the manufacturing process of the stick-shaped cosmetic of the present invention, after the molding die is preheated ( Figure 3A This allows the heated and molten cosmetic composition to flow into the molding die. Figure 3B ), using Peltier elements for reheating (reheating) Figure 3C ) and cooling curing ( Figure 3D After that, it separates from the forming mold and is formed. Figure 3E ).

[0103] In this invention, with Figure 1 Unlike previous examples, during cooling and curing, the process is implemented not based on wind but on direct heating (reheating) of the Peltier element and gradual cooling based on cyclic cooling.

[0104] Next, use Figures 4-7 The structure for adjusting the temperature of the lipstick forming device in the first embodiment of the back filling method based on the present invention will be described.

[0105] Figure 4 This is a perspective view of the temperature adjustment section of the lipstick forming apparatus according to the first embodiment of the present invention. Figures 5A to 5C This is a diagram showing a specific example of a heat sink. Figure 6 This is a diagram showing the periphery of the moving part of the substrate in the refrigerant tank. Figure 7 It is shown Figures 3A-3E A cross-sectional view of multiple independent forming units in a manufacturing apparatus arranged in the conveying direction. Figure 7 It shows the relationship with Figure 4 The cross-section of the temperature adjustment section for different cooling methods.

[0106] Figure 4 The temperature adjustment device 102 of the lipstick forming apparatus 100 includes multiple forming molds 1, multiple outer cylinders 2, Peltier elements 3, a heat sink 4, a controller 5, a refrigerant tank 6, and a cooling unit 7. The heat sink 4 is a component for cooling the Peltier elements, the refrigerant tank 6 uses a first refrigerant C to cool the heat sink 4, and the cooling unit 7 uses a second refrigerant W in the refrigerant tank to cool the first refrigerant C. Furthermore, a base plate 50 for configuring the controller 5 may also be provided.

[0107] Figure 4 The lipstick forming apparatus involved shows a cooling structure in which multiple forming molds 1 (1-1, 1-2, 1-3, 1-4), multiple outer cylinders 2 (2-1, 2-2, 2-3, 2-4), and Peltier element 3 are cooled by a radiator 4, which is cooled by two types of refrigerants.

[0108] The first refrigerant C is, for example, an oily refrigerant such as a hot grease with high thermal conductivity. The second refrigerant W in the cycle is preferably, for example, water (cooling water), ethanol, ethylene glycol, polyols, and aqueous solutions thereof, which have high specific heat and high fluidity.

[0109] The forming mold 1 is a bottomed cylindrical mold for filling a stick-shaped cosmetic composition into a cylindrical recess. Multiple forming molds 1 are provided in a number that can fill at least one lipstick.

[0110] The outer cylinder 2 is a retaining part that surrounds at least one side of each of the multiple forming molds 1. The outer cylinder 2 is arranged in such a way that the multiple forming molds 1 do not affect the temperature of the filling material.

[0111] In this embodiment, the outer cylinder 2 is an insulation cylinder, which prevents temperature interference between adjacent forming molds 1 by separating them from each other. In addition, in this example, the same number of outer cylinders 2 are provided for each forming mold 1, but it is not necessary to provide the same number. As long as the temperatures of the forming molds do not interfere with each other, one cylinder can also be provided for multiple forming molds 1 (10th and 11th embodiments).

[0112] The Peltier element 3 contacts at least a portion of the lower surface of the forming mold 1 and the lower surface of the outer cylinder 2, enabling it to heat or cool the forming mold 1. In this embodiment, four forming molds 1 and four outer cylinders 2 are provided, and one Peltier element 3 is provided in contrast.

[0113] Controller 5 is an example of a control unit. It is electrically connected to the Peltier element 3 and controls the value and direction of the energized current, thereby adjusting the temperature of each molding die 1 via each Peltier element 3. Controller 5 is mounted on the upper surface of substrate 50. Since each cooling unit requires a controller 5, substrate 50 is necessary.

[0114] Heat sink 4 is positioned below Peltier element 3 to cool Peltier element 3 from below. Peltier element 3 and heat sink 4 need to be in direct contact.

[0115] Figures 5A to 5C This is an enlarged view of the radiator. Figure 5A This is a top perspective view of the radiator 4 in the first structural example. Figure 5B This is a top perspective view of the radiator 4A in the second structural example. Figure 5C This is a perspective view of the heat sink 4B in the third structural example.

[0116] like Figure 5A As shown, the radiator 4 has an upper surface pad 41 on the upper side and a plurality of comb-shaped, prismatic rod-shaped protrusions (rod-shaped pendants) 42 extending downward from the lower surface of the upper surface pad 41. The upper surface pad 41 (41A) of the radiator 4, which serves as the base, can be as follows: Figure 5A It can be a quadrilateral, or it can be a circle. The protrusion can also be like... Figure 5B As shown, it is a cylindrical rod-shaped protrusion 42A, or as... Figure 5C As shown, it is a planar protrusion (plate-like protrusion) 43.

[0117] Since the heat sink 4 of this shape cools the Peltier element 3, the heat sink 4 is preferably in direct contact with the Peltier element 3 or in contact with the Peltier element via the substrate 50.

[0118] exist Figure 4In this example, the heat sink 4 is located below the Peltier element 3 in a manner capable of cooling the Peltier element 3. The substrate 50 functions as a base such that the Peltier element 3, the heat sink, and the controller are configured as a transportable unit.

[0119] Furthermore, in the temperature adjustment device 102, the four forming molds 1, four outer cylinders 2, one Peltier element 3, the substrate 50, the controller 5, and the heat sink 4 on the upper side are combined as an independent temperature control unit α.

[0120] The refrigerant tank 6 stores refrigerant C for cooling the radiator 4. In the case of a cooling method with a cooling unit 7, the first refrigerant C is preferably a thermally conductive grease, but it can also be water, ethanol, ethylene glycol, polyols, and aqueous solutions thereof. Inside the refrigerant tank 6, a portion or the entire lower periphery of the protrusions 42, 42A, 43 constituting the comb-like portion of the radiator 4 is immersed in the first refrigerant C.

[0121] In addition, the refrigerant tank 6 is composed of side walls 61 and bottom walls 62. The independent temperature control unit α can... Figure 6 In this way, it is transported and moved within the refrigerant tank 6 via casters 59 and the like, which are provided on both sides of the base plate 50. Furthermore, Figure 6 The conveying method shown is one example. The conveying method for the independent temperature control unit α of the present invention is not limited to this, and can also be based on conveying by an electric cylinder, etc.

[0122] With this structure, the radiator 4 can be stably cooled during the transport of the independent temperature control unit α, and the radiator 4 can be cooled without problems even if the lower part of the radiator 4 is worn due to transport.

[0123] A cooling unit 7 is formed below the refrigerant tank 6. The cooling unit 7 has a cooling passage 71 and a housing 72. The housing 72 has a water inlet passage 73 and a drain passage 74 on its front side, which are connected to the cooling passage 71. A second refrigerant W for cooling flows inside the cooling passage 71, which is arranged in a meandering manner within the cooling unit. The cooling unit 7 is preferably a metal plate with high thermal conductivity, and is stably and uniformly cooled by the circulating second refrigerant W.

[0124] In the case of having a cooling unit 7, the radiator 4 below the Peltier element 3 is cooled from the cooling unit 7 after being cooled by the second refrigerant W via the box 6 and the first refrigerant C inside the box 6.

[0125] In addition, Figure 4The example described above includes a cooling unit 7, but in the case of circulating and cooling the first refrigerant C in the refrigerant tank 6, the cooling unit 7 may not be required. In the case where the cooling unit 7 is absent but the first refrigerant C in the cooling tank is circulated, water, ethanol, ethylene glycol, polyols, and their aqueous solutions are preferred, as circulation is the primary consideration.

[0126] The Peltier element 3 has the property of absorbing heat on one side while releasing heat on the other side. Therefore, when heating the upper surface, it is preferable that the back side be cooled. Thus, by cooling the lower surface side with refrigerant C, it is possible to help the upper surface of the Peltier element 3 absorb heat during heating and suppress the overheating of the back side during cooling.

[0127] Figure 7 This is a cross-sectional view showing the arrangement of independent forming units in the conveying direction. Figure 7 In this embodiment, multiple outer cylinders 2 surrounding multiple forming molds 1 are arranged separately from each other without contact. In this embodiment, an example is shown where four Peltier elements 3 are provided relative to the forming molds 1, and one Peltier element 3 is provided.

[0128] Furthermore, since each Peltier element 3 is also arranged separately from each other, the independent temperature control unit α is arranged separately from each other in a way that prevents temperature interference between adjacent Peltier elements 3. As will be described later, the Peltier elements 3 change their set temperature according to the elapsed time after filling, therefore Figure 7 The three Peltier elements 3 shown can also be set to different temperatures.

[0129] Figure 4 The temperature control section of the lipstick forming device involved explains that it uses two types of refrigerants for cooling, but... Figure 7 In the temperature adjustment unit shown, radiator 4 is an air-cooled cooling mechanism. Therefore, no refrigerant is used.

[0130] In addition, Figure 4 In the temperature adjustment section of the lipstick forming apparatus, an example is shown where a controller 5 on the substrate 50 is equipped with a power transmission device 500 for transmitting temperature to the Peltier element, but... Figure 7 In the temperature adjustment section shown, a wireless power transmission device 500α that supplies power to the Peltier element 3 (element-side controller) is provided on the underside of the radiator 4 and the conveyor belt 65.

[0131] In this embodiment, within the independent temperature control unit α, the parts for forming a lipstick, excluding the Peltier element 3 and the heat sink 4, are designated as independent forming units β. These forming units β are also arranged separately from each other in a manner that prevents temperature interference.

[0132] Figure 8A , Figure 8B This is an illustration of the wired power transmission to the independent temperature control unit α. Figure 8A This is a top-down explanatory diagram. Figure 8B This is a side view illustration. For the program to operate via the Peltier element 3, power needs to be supplied to both the Peltier element 3 and the controller 5. Figure 8A , Figure 8B In the example shown, in order to allow the independent temperature control units α (α-11~α-10, α-21~α-20) and controllers 5 (5-11~5-10, 5-21~5-20) arranged in two columns of 10 units to freely and safely receive and receive power, the power is supplied below via a wired connection.

[0133] In addition, Figure 8A , Figure 8B The diagram shows wired power transmission, but it can also wirelessly transmit a program to controller 5 that sets a cooling profile best suited for the application of the cosmetic composition. In this case, the independent control unit α can each execute the program. For example, in... Figure 4 In the middle, a wireless power transmission device is located on the front side of the controller 5. Figure 7 In the middle, there is a wireless power transmission device at the bottom.

[0134] In addition, in this embodiment, each forming mold 1, which has four independent temperature adjustment units α, has a rubber mold 11, a metal mold 12, and rubber retainers 13 and 14.

[0135] The rubber mold 11 is a mold made of an elastomer such as silicone rubber or fluorosilicone rubber, which has a cylindrical recess and directly fills the recess with lipstick (stick cosmetic) composition (cosmetic composition) L.

[0136] The metal mold 12 is an example of a bottomed cylindrical heat transfer mold that surrounds the sides and bottom surface of the rubber mold 11. The heat transfer mold is made of metals with good thermal conductivity, such as copper or aluminum, or graphite.

[0137] In addition, in order to form the lipstick tightly against a part of the dispensing container 8 when the lipstick composition L is filled, a lifting cylinder 83, an outer spiral cylinder 82, and an outer cylinder 81, which are part of the dispensing container 8, are installed above the independent forming unit α.

[0138] The inner retainer 13 of the forming mold 1 surrounds and holds the lifting cylinder 83 that holds the formed rod-shaped cosmetic L tightly, and the spiral cylinder 82 that engages with the outer side of the lifting cylinder 83, and clamps and holds the rubber mold 11 with the retainer 14.

[0139] The outer retainer 14 surrounds and holds the outer side of the inner retainer 13, and is connected to the metal mold 12 and the outer cylinder 2.

[0140] In addition, Figure 7 In this example, the outer retainer 14 is bent into an approximately L-shaped cross section. The positions of the lifting cylinder 83 and the spiral cylinder 82 are fixed through a part of the outer retainer 14 and the contact between the rubber mold 11 and the metal mold 12.

[0141] In addition, in this embodiment, the outer cylinder 2, which serves as the retaining part surrounding the forming mold 1, has an outer sidewall 21 and an upper sidewall 22.

[0142] Additionally, refer to Figure 4 and Figure 7 The multiple Peltier elements 3 are arranged such that they widen in the horizontal direction compared to the height direction, and the lower ends of the four forming molds 1 are in contact with the upper surface of one Peltier element 3. Therefore, in this embodiment, each of the multiple Peltier elements 3 can be heated or cooled for each of the four forming molds 1.

[0143] In this embodiment, the lifting cylinder 83 and the spiral cylinder 82 are held by rubber retainers 13 and 14. With the outer cylinder 81 on the upper side, the lipstick composition L is filled into each recess of each forming mold 1 and the inner side of each lifting cylinder 83. The temperature of the lipstick composition L in the rubber mold 11 and the lifting cylinder 83 is adjusted by the Peltier element 3. By adjusting the Peltier element 3 to a predetermined temperature, the metal mold 12 is heated or cooled from the bottom (bottom heating, bottom cooling), and the lipstick composition L is heated or cooled from the bottom or from the side according to the shape of the metal mold 12.

[0144] Furthermore, the ratio of the number of forming molds 1 to the number of Peltier elements 3 is not limited to 4:1; the number of Peltier elements 3 can be 1 / n (where n is a natural number greater than 2) to 1 / 1 of the number of forming molds 1. In this case, the lower ends of 1 to n forming molds 1 and the outer cylinder 2 are in contact with the upper surface of one Peltier element 3, and each Peltier element of the plurality of Peltier elements can be heated or cooled for each of the 1 to n forming molds.

[0145] exist Figure 4 , Figure 7In the embodiment shown, the outer cylinder 2 functions as a heat insulation cylinder that retains heat from the mold and prevents heat transfer to other molds. Conversely, it also has a heat insulation function that prevents heat from other molds from affecting the mold inside the outer cylinder. Therefore, by separating them, temperature interference between adjacent molding molds 1 is prevented. Furthermore, in this example, an example is described where the same number of outer cylinders 2 are provided for each molding mold 1, but this is not mandatory. As long as the temperatures of the molding molds do not interfere with each other, one outer cylinder 2 can also be provided for multiple molding molds 1 (10th and 11th embodiments).

[0146] (Manufacturing process)

[0147] Here, in Figure 9 The diagram illustrates the manufacturing process of the lipstick dispensing container of the present invention. Furthermore, the manufacturing process also shows the back-filling method. Figures 10A to 10C This is a cross-sectional view illustrating the position of the discharge tube in the discharge container during back filling. Figure 10A This is a diagram showing the position of the discharge tube in the discharge container during its formation. Figure 10B This diagram shows the position when the discharge tube has been retracted. Figure 10C This is a diagram showing the position when the cover is fitted.

[0148] Reference Figures 3A-3E , Figure 9 , Figures 10A to 10C To illustrate the back filling method based on the present invention, the process of the back filling method is described.

[0149] In step S1, the lifting cylinder (middle cylinder) 83, the spiral cylinder 82, and the outer cylinder (sleeve) 81 are installed onto the forming mold 1 (set as follows). Figure 3A (The state). Alternatively, simply install the lifting cylinder 83 onto the forming mold.

[0150] In step S2, the forming mold 1 is preheated (refer to...). Figure 3A ).

[0151] In step S3, the lipstick composition (cosmetic composition) is filled into the forming mold 1 and the lifting cylinder 83 (see reference). Figure 3B ).

[0152] In step S4, the forming mold 1 is heated and cooled by adjusting the temperature of the Peltier element 3. Figure 3C , Figure 3D ).

[0153] S3 and S4 constitute the lipstick forming process performed by the lipstick forming device 100.

[0154] In step S5, the formed lipstick L, lifting cylinder 83, spiral cylinder 82, and outer cylinder 81 are removed from the forming mold 1. That is, demolding is performed. Alternatively, if only the lifting cylinder 83 is installed on the forming mold 1, in this step, the spiral cylinder 82 and outer cylinder 81 are engaged with the lifting cylinder 83, and the formed lipstick L and lifting cylinder 83 are removed from the forming mold. After S5, an inspection step for inspecting the formed lipstick may also be provided.

[0155] That is, in steps S1 to S5, such as Figure 10A As shown, the lipstick is formed in the discharge container 8, with the lifting cylinder 83 having discharged the spiral cylinder 82.

[0156] In step S6, by rotating the spiral cylinder (sleeve) 82 and the outer cylinder 81 relative to each other, the lipstick and the lifting cylinder 83 are retracted together to a position where at least the top of the formed lipstick does not protrude from the upper end of the spiral cylinder 82 (see reference). Figure 10B ).

[0157] In step S7, the lifting cylinder 83, the spiral cylinder 82, and the outer cylinder 81 are engaged with other components to assemble the discharge container 8. Furthermore, in the back-filling method, this step is unnecessary when filling the lipstick composition L with all components of the discharge container 8 prepared.

[0158] In step S8, the cap 89 and the discharge container 8 are combined to complete the manufacturing process (see reference). Figure 10C ).

[0159] like Figure 9 , Figures 10A to 10C As shown, in this embodiment using the back filling method, since the lipstick is formed by connecting a part of the dispensing container to the forming mold, the part of the lipstick after filling temperature control can be manufactured without changing the general manufacturing method of the dispensing container with lipstick.

[0160] <First Structural Example of the Metal Mold in the First Embodiment>

[0161] Figures 11A to 11C This is an explanatory diagram of the independent forming unit β1 of the metal mold according to the first structural example of the first embodiment. Figure 11A This is a cross-sectional view of the independent forming unit β1 of the first structural example. Figure 11B From Figure 11A The top perspective view of the independent forming unit β1 without the outer cylinder 2A and Peltier element 3 is shown. Figure 11C yes Figure 11B A three-dimensional image viewed from below.

[0162] In this embodiment, with Figure 7Similarly, each forming mold 1A consists of a rubber mold 11, a metal mold 12A, and retaining parts 13A and 14A.

[0163] In this structural example, the upper parts of the retainers 13A and 14A are straight, linear portions 131 and 141, which do not contact the outer cylinder 2A. Furthermore, the lower ends of the retainers 13A and 14A are anti-slip portions 132 and 142, bent inwards into a hook-shaped cross-section. Additionally, in this embodiment, a design similar to... Figure 7 Outer sleeves 2A and retainers 13A and 14A of different shapes.

[0164] In addition, Figures 11A to 11C and the following Figures 12A-12C and Figures 13A-13C The diagram shows an example of the outer cylinder 2A and retainers 13A and 14A, which are common to the shapes of the metal molds 12A and 12B, but combinations of these structures are also possible. Figure 7 The outer sleeve 2, retaining parts 13 and 14 of the structure.

[0165] The rubber mold 11 has a side surface 111, a bottom surface 112, a flange 113, and an annular raised protrusion 114. The side surface 111 and bottom surface 112 are portions that, as a bottomed tube, are directly filled with the lipstick composition. The flange 113 extends outward from the upper end of the side surface 111. The annular raised protrusion 114 rises upward and / or downward from the outer end of the flange 113. Furthermore, the structure of the inner side of the rubber mold 11... Figure 7 , Figures 11A to 11C , Figures 12A-12C , Figures 13A-13C Common to both.

[0166] In this structural example, the metal mold 12A has a side surface 121, a bottom surface 122, and an upper annular groove 123. In this structure, the lower surface of the bottom surface 122 of the metal mold 12A is in contact with the Peltier element 3. Therefore, during heating and cooling, the bottom surface 122 directly receives temperature transfer from the Peltier element 3. Moreover, the side surface 121 of the metal mold 12A surrounds the side surface 111 of the rubber mold 11. Thus, this structural example is one in which the rubber mold 11, whose entire bottom surface is in contact with the Peltier element 3, receives temperature transfer from the lower Peltier element 3 and is heated and cooled from bottom to top, thereby heating and cooling the lipstick composition L from the bottom surface (lower heating and lower cooling).

[0167] also, Figure 11A , Figure 12A P1 and P2 in the diagram illustrate what will be described later. Figure 23A , Figure 23B The temperature measurement was performed on the lipstick, showing its top and bottom positions.

[0168] <Second structural example of the metal mold in the first embodiment>

[0169] Figures 12A-12C This is an explanatory diagram of the independent forming unit β2 of the metal mold according to the second structural example of the first embodiment. Figure 12A This is a cross-sectional view of the independent forming unit β2 in the second structural example. Figure 12B From Figure 12A The top-view perspective of the independent forming unit β2, excluding the outer cylinder 2A and Peltier element 3, is shown. Figure 12C yes Figure 12B A three-dimensional image viewed from below.

[0170] In this structural example, the metal mold 12B is a double-cylinder structure, configured to include a holding cylinder 124, an outer heat transfer cylinder 125, and a connecting part 126.

[0171] The holding cylinder 124 is a bottomed cylinder with sides 124a and bottom 124b surrounding the sides 111 and bottom 112 of the rubber mold 11. This design ensures that the lower surface of the bottom 124b does not directly contact the Peltier element 3. The holding cylinder 124 is shorter than the outer heat transfer cylinder 125, and its bottom 124b does not directly contact the Peltier element 3. Specifically, by forming a bottomed cylindrical space 127 that rises from the lower surface between the holding cylinder 124 and the outer heat transfer cylinder 125, the lower center of the metal mold 12B does not directly contact the Peltier element 3.

[0172] In this structure, since the side 124a of the holding cylinder 124 of the metal mold 12B surrounds the side 111 of the rubber mold 11, the heating and cooling temperatures are also transferred from the circumferential direction of the lipstick, resulting in lateral heating and lateral cooling.

[0173] The outer heat transfer cylinder 125 is a cylindrical portion that surrounds the holding cylinder 124 separately from its outer surface and whose lower end contacts the Peltier element 3. The outer periphery of the outer heat transfer cylinder 125 contacts the inner periphery of the outer cylinder 2A.

[0174] The connecting part 126 connects the upper end of the holding cylinder 124 and the upper end of the outer heat transfer cylinder 125.

[0175] In this structure, since the lower end of the lipstick-holding cylinder 124 is not in contact with the Peltier element 3, it is not directly heated from below. The heat from the Peltier element 3 is indirectly cooled from the lower end of the holding cylinder 124 by spreading in the lower space of the bottom cylindrical space 127. Moreover, the heat transferred from the Peltier element 3 is transferred from the upper side to the lower side of the holding cylinder 124 through the outer heat transfer cylinder 125 and the upper connecting part 126. Therefore, the cooling of the lifting cylinder 83 holding the lipstick can be accelerated before the cooling of the top part of the lipstick. Thus, in this structural example, the temperature is transferred from the lower Peltier element 3, the central bottom surface is not in contact with the Peltier element 3, and the side surface 124a of the holding cylinder 124 surrounding the periphery heats and cools the side surface 111 of the rubber mold 11 from top to bottom. As a result, the lipstick composition L is heated and cooled from the side (side heating and side cooling).

[0176] <Third structural example of the metal mold in the first embodiment>

[0177] Figure 13A This is an explanatory diagram of the independent forming unit β3 of the metal mold according to the third structural example of the first embodiment. Figure 13A This is a cross-sectional view of the independent forming unit β3 of the third structural example. Figure 13B From Figure 13A The top perspective view of the independent forming unit β3 without the outer cylinder 2A and Peltier element 3 is shown. Figure 13C yes Figure 13B A three-dimensional image viewed from below.

[0178] In this structural example, the metal mold 12C is a cylindrical shape with a bottom, and like the metal mold 12A, it has a side surface 121C, a bottom surface 122C, and an upper annular groove 123. However, in this structural example, the bottom surface 122C is larger than... Figure 11A Thin, the lower part of the inner side of side 121C and Figure 11A Compared to thinning in an expanded manner, a cylindrical space 128 with a bottom is formed on the bottom surface 122C, serving as a gap between the metal mold 12C and the rubber mold 11. Thus, the side surface 121C of the metal mold 12C contacts the upper part 111a of the side surface of the rubber mold 11 but not the lower part 111b. Furthermore, the bottom surface 122C does not contact the bottom surface 112 of the rubber mold 11.

[0179] In this structure, since the contact area between the bottom 122C of the metal mold 12C and the Peltier element 3 is larger than that of the metal mold 12B, the heat transfer efficiency is excellent. On the other hand, since the bottom surface 112 of the rubber mold 11 does not contact the metal mold 1C, it is heated and cooled by the upper side 111a of the rubber mold 11 that is in contact with the metal mold 12C, thus achieving lateral heating and lateral cooling.

[0180] In this structure, since the lower end of the rubber mold 11 holding the lipstick is not in contact with the bottom surface 122C of the metal mold 12C, it is not directly heated or cooled from the bottom. The heat of the Peltier element 3 is indirectly heated or cooled from the lower end of the rubber mold 11 by spreading in the metal mold 12C and the bottomed cylindrical space 128 on the upper side.

[0181] Because air has very poor thermal conductivity, in this structure, heat transfer occurs not from the lower end, but through the upper side 111a that is in contact with the side 121C. This allows for rapid cooling of the portion of the lipstick held by the lifting cylinder 83A compared to the lower top of the lipstick. Therefore, in this structural example, temperature is transferred from the lower Peltier element 3, and the bottom surface 112 and lower side 111b of the rubber mold 11 do not contact the metal mold 12C. Heating and cooling occur from the upper side 111a of the rubber mold 11, thereby heating and cooling the lipstick composition L from the side (side heating and side cooling).

[0182] <Temperature distribution of lateral cooling>

[0183] Here, use Figures 14A to 14D This is to illustrate the temperature distribution and contraction direction of the lower and side cooling systems. Figure 14A It is shown in Figure 1 A graph showing the temperature distribution of a lipstick composition in a typical molding process where hot air is used to heat the composition from top to bottom. Figure 14B It is shown in Figure 14A A diagram showing the shrinkage direction of a formed lipstick. Figure 14C This is a graph showing the temperature distribution of a lipstick composition when heated from above and cooled from the sides using hot air. Figure 14D It is shown in Figure 14C A diagram showing the shrinkage direction of a formed lipstick.

[0184] Figure 14B , Figure 14D The dashed arrow in the image indicates the direction of shrinkage of the lipstick L due to cooling. (In the image...) Figure 14A In that case of cooling from below, the lipstick composition... Figure 14B It contracts downwards, thus creating a contraction opening at the upper end.

[0185] In contrast, in such Figure 14C In this side-cooling configuration, the lipstick composition is cooled and solidified from the side first, thus reducing internal deformation in the vertical direction and minimizing shrinkage pores at the top. Furthermore, since the lateral section is shorter than the longitudinal section, the temperature difference between the top and bottom of the lipstick is smaller, further reducing lateral internal deformation.

[0186] There is a lifting cylinder on the side that holds the lipstick in place. By rapidly cooling this area, the crystal structure of the wax can be refined, thus allowing for the expectation that... Figure 14A In contrast, reducing the temperature difference between the top and bottom of the lipstick composition can improve its overall strength. Therefore, shrinkage pores are less likely to form.

[0187] Furthermore, during lateral cooling, solidification occurs from the side, so... Figure 14D As shown, air can easily enter after molding. Therefore, during demolding after back molding, the pressure relief effect of air entry on the solid molded part can be expected, making it easier to remove during demolding.

[0188] (Experimental Example)

[0189] The inventors of this application, in order to provide empirical evidence... Figures 14A to 14D Given that temperature distribution and shrinkage tendency, forming experiments were conducted using bottom cooling and side cooling.

[0190] Figure 15 This table shows the experimental results of shrinkage pores in lipstick forming based on bottom cooling and side cooling as comparative examples. Six lipsticks, No. 1 to No. 6, were filled with lipsticks at the same filling temperature and cooling temperature, and then cooled using different cooling methods.

[0191] exist Figure 15 In the examples, No. 1 to No. 3 are examples of temperature control using hot and cold air from below, while No. 4 to No. 6 are examples of temperature control using hot and cold air from the side, which are examples of temperature control that imitates the present invention.

[0192] exist Figure 15 In this context, the reheat temperature indicates whether the hot air temperature is high or low. Additionally, in... Figure 15 In the description of the degree of shrinkage pores, ○ means no pores, △ means there are pores of 2-3 mm but no problem, and × means there are large pores of 4 mm or more.

[0193] Generally speaking, the lower the reheat temperature, the more likely shrinkage pores will form. Furthermore, as shown in No. 6, the lower the reheat (heating of the base of the lipstick) temperature, the more significantly the shrinkage pores are reduced when cooling the side compared to the bottom cooling in No. 3.

[0194] Figure 16This table shows the experimental results of the hardness and breakage resistance of lipsticks formed using bottom cooling and side cooling as comparative examples. The three lipsticks No. 7 to No. 9 are examples where temperature control was achieved through hot and cold air from the bottom, while the three lipsticks No. 10 to No. 12 are examples where temperature control was achieved through hot and cold air from the side, mimicking the present invention.

[0195] exist Figure 16 In this context, the lipstick's resistance to breakage is determined through a contact friction test after the lipstick has been formed. Under common conditions, a value of 0 is used to indicate that the lipstick did not break, while a value of × indicates that it broke. Additionally, the hardness deviation is expressed as the ratio of the hardness at the tip to the hardness at the base.

[0196] according to Figure 16 The table shows that, by filling lipstick at the same filling temperature and cooling temperature and then cooling it using different cooling methods, side cooling suppressed the overall hardness deviation compared to bottom cooling (No. 10 to No. 12).

[0197] Furthermore, when comparing No.12, which particularly suppressed deviations, with No.9, which was produced under the same conditions except for the cooling method, its resistance to breakage was significantly improved.

[0198] according to Figure 15 , Figure 16 The experiment can be described as: compared to... Figures 14A to 14D As expected, the effects of lateral cooling include: (1) reduced shrinkage pores; and (2) unlike the previous cooling from the bottom which solidifies from the tip of the lipstick, the hardness deviation is suppressed and it is not easy to break because it solidifies from the base of the lipstick.

[0199] <Regarding Cooling>

[0200] Here, in Figure 17 The table below shows the properties of the lipstick when rapidly cooled and gradually cooled. For example... Figure 17 As shown, generally speaking, the hardness decreases when the deformation is large and the crystal size is large. On the other hand, the hardness increases when the deformation is small and the crystal size is small.

[0201] Therefore, in terms of manufacturing process, if the crystal is cooled rapidly to reduce its size, the deformation will be greater; if it is cooled gradually to reduce deformation, the crystal will be larger.

[0202] Therefore, optimizing these opposing phenomena becomes crucial for temperature control. Specifically, the preferred approach is to optimize the process by determining which temperature range should be rapidly cooled and which should be gradually cooled.

[0203] Because this invention uses a Peltier element to control temperature, it can achieve temperature control freely without the need for additional devices or changes in device configuration, compared to the use of hot or cold air to control temperature.

[0204] <Cooling Temperature Optimization>

[0205] Therefore, the inventors of this application conducted a comparative experiment on crystals under two temperature shifts in order to optimize the temperature control process.

[0206] Figure 18 This is a graph showing the temperature progression during experiments in temperature mode 1 (rapid cooling) and temperature mode 2 (gradual cooling). Figure 18 In the middle, temperature mode 1 is a temperature mode of sudden cooling from the beginning to the end of cooling, and temperature mode 2 is a temperature mode of sudden cooling, temporary heating, gradual cooling and then sudden cooling from the beginning to the middle of cooling.

[0207] Figure 19 It is shown Figure 18 Microscopic images of lipstick crystals under rapid cooling temperature mode 1. Figure 19 In the diagram, t11 shows the crystal state at 76°C during quenching, and t12 shows the crystal state at 37°C after quenching. Under the uniform quenching cooling mode of temperature mode 1, as shown... Figure 19 As shown in t12, many crystal nuclei appear by rapidly cooling the crystal precipitation temperature. Furthermore, it can be seen that: Figure 19 At the end of cooling as shown in t12, due to Figure 19 The crystal growth is based on the crystal nuclei shown in t11 after the initial cooling, so the size of the crystal is determined by the number of crystal nuclei.

[0208] Figure 20 It is shown Figure 18 Microscopic images of lipstick crystals in various processes under rapid cooling temperature mode 2. Figure 18 Under the temperature mode 2 shown, after quenching from 90°C (first quench) to 72°C, the temperature is raised to 77°C, maintained at 77°C for 30 minutes, and then slowly cooled to 60°C (gradual cooling). After that, it is cooled to 37°C at the same temperature gradient as in temperature mode 1 (second quench).

[0209] exist Figure 20 In the diagram, t21 shows the crystal state at 76°C during quenching, t22 shows the crystal state at 72°C after quenching, t23 shows the crystal state at 77°C immediately after heating, t24 shows the crystal state after maintaining 77°C for 30 minutes after heating, and t25 shows the crystal state at 37°C after gradual cooling.

[0210] In the rapid cooling of temperature mode 2, by using Figure 18 , Figure 20 of The crystal precipitation region is rapidly cooled to temporarily maintain the number of crystal nuclei by reducing the crystal size. Then, with... Heat to a temperature close to the complete melting temperature.

[0211] Next, through Maintain a temperature close to the complete melting temperature, and keep the temperature at the top and bottom of the crystal nucleus the same without changing the nucleus.

[0212] Moreover, it can be seen that: by using The rapid cooling after gradual cooling and uniform solidification is reproduced, and crystal growth is carried out under the condition of the size of the precipitated crystals.

[0213] If comparison Figure 19 Photos of the T12 and Figure 20 From the photo of t25, it can be seen that: regarding the control of cyclic cooling through temperature mode 2, although the deformation is reduced by uniform solidification, it is possible to form rod-shaped cosmetics with no difference in crystal size and not easy to break by rapidly cooling the temperature range that forms the crystal structure.

[0214] Thus, in temperature mode 2, the crystal size can be reduced by rapidly cooling the temperature range in which the crystal structure is formed, and deformation can be eliminated by gradually cooling back to the temperature close to complete melting.

[0215] (Temperature control example of the present invention)

[0216] Next, use Figure 21 , Figure 22 Regarding reference Figure 18 The temperature control of the present invention will be described in detail in temperature mode 2, which optimizes the temperature control process.

[0217] Figure 21 It shows the use Figure 11A The temperature setting example of the cosmetic and the temperature shift of the top and bottom of the lipstick composition under the condition that the independent molding unit β1 of the first structural example is subjected to temperature control of cyclic cooling. Figure 22 This is the temperature control process in the lipstick forming process of the present invention.

[0218] use Figure 21 and Figure 22 The temperature control process for curing the cosmetic composition of the present invention will be described.

[0219] In S51, the temperature of the Peltier element 3 is cooled from the filling temperature to the first temperature (first quench). The first temperature is set to a temperature below the wax crystal precipitation temperature, that is, a temperature close to the complete melting temperature.

[0220] In S52, the temperature of the Peltier element 3 is maintained at the first temperature for a predetermined period. The cooling in S51 and S52 is a process of temporarily cooling the molten material in the molding die to a predetermined solidification temperature, i.e., the first temperature.

[0221] In S53, the temperature of the Peltier element 3 is raised to a second temperature lower than the filling temperature.

[0222] In S54, the temperature of the Peltier element 3 is maintained at the second temperature for a predetermined period. S53 and S54 are reheating, and the second temperature is set to the temperature at which the raw material will not melt again, i.e., the temperature at which wax crystal precipitation begins.

[0223] In S55, the temperature of the Peltier element 3 is gradually reduced from the second temperature to the third temperature (gradual cooling). The third temperature is set to be below the temperature at which wax crystals precipitate.

[0224] In S56, the temperature of the Peltier element 3 is maintained at the third temperature for a predetermined period.

[0225] In S57, the temperature of the Peltier element 3 is cooled from the third temperature to the final cooling temperature (second quench). The final cooling temperature is set to the temperature at which the curing material is completely cured.

[0226] In S58, the process ends after the temperature of the Peltier element 3 is maintained at the final cooling temperature for a predetermined period.

[0227] Here, the first temperature is set lower than the crystal precipitation temperature, and by rapid cooling, the crystal nuclei can be generated in small sizes.

[0228] In S55 to S57, a cyclic cooling process is implemented, in which the temperature decreases in stages from the second temperature to the final cooling temperature, with a maintenance period at a third temperature close to the second temperature.

[0229] In this invention, since the temperature of the Peltier element, which directly adjusts the temperature of the forming mold, is directly adjusted, the heating and cooling processes can be added without the need for special additional devices for heating and cooling.

[0230] By using this phased, cyclical cooling method, the cooling time can be adjusted.

[0231] Furthermore, as shown in the graph, the Peltier element of the present invention can control the temperature adjustment of the lipstick molding material in a programmed manner, and can shift the temperature of the tip and base of the lipstick composition according to the set temperature of the Peltier.

[0232] <Temperature shift by location>

[0233] Figure 23A , Figure 23BThese are diagrams showing the temperature shift of the stick-shaped cosmetic at different locations when temperature control is achieved via Peltier control in the first and second structural examples shown in Figures 11 and 12.

[0234] Figure 23A This is a temperature shift curve in the first structural example in Figure 11. Figure 23B This is a graph showing the temperature shift in the second structural example in Figure 12.

[0235] As an initial condition, the Peltier element 3 is set to 90°C, and the lipstick composition L, the lifting cylinder 83, and the rubber mold 11 are preheated to 90°C. Then, the Peltier element 3 is allowed to decrease from 90°C to -10°C over 90 seconds, starting 10 seconds after the start. Figure 23A , Figure 23B The solid line shows the shift of the set temperature of the Peltier element 3.

[0236] As the temperature of the upper part of the lipstick composition at this time, a position 2 mm from the upper part was measured. Figure 11A , Figure 12A The temperature at position P1 was used as the lower end temperature, and the temperature at a position 2 mm from the lower end was measured. Figure 11A , Figure 12A The temperature at the location of P2. Figure 23A , Figure 23B The gray line indicates the upper temperature of the lipstick composition, and the dashed line indicates the lower temperature of the lipstick composition.

[0237] If comparison Figure 23A and Figure 23B The curves show that, regardless of which curve is used, the upper and lower temperatures of the lipstick composition decrease in accordance with the set temperature of the Peltier element 3. Therefore, regardless of the structure of the metal molds 12A and 12B used, the temperature can be controlled using the Peltier element 3.

[0238] Here, in Figure 23B In the second structural example shown in Figure 12, there is almost no temperature difference between the upper and lower ends, and both the upper and lower ends are cooled with a slight delay from the set temperature. Therefore, it can be expected that the deformation (shrinkage pores, etc.) around the center of the lipstick will be smaller due to the rapid cooling of the center area first, and the strength of the lipstick will be improved by reducing the crystal size at the root.

[0239] On the other hand, such as Figure 23A , Figure 23B As shown in the graph, it can be seen that: compared to controlling the temperature of the Peltier element 3 to reach 0°C in approximately 82 seconds after the initial 10 seconds, in Figure 23AIn the middle, the lower part of the lipstick reaches 0°C in approximately 83 seconds, and the upper part of the lipstick reaches 0°C in approximately 89 seconds, but... Figure 23B In the test, both the bottom and top of the lipstick reached 0°C in approximately 93 seconds.

[0240] Therefore, we can know that: Figure 23A The first structural example in Figure 11 used in the same way as in Figure 23B Compared to the structural example in Figure 12 used, the temperature transfer delay of the lipstick composition L relative to the Peltier element 3 is less. This can be attributed to the fact that the metal mold 12A shown in Figure 11 covers the entire inner area of ​​the outer cylinder 2, thus providing more contact surface with the Peltier element 3 and resulting in better transfer efficiency compared to the metal mold 12B, which only partially covers the inner area of ​​the outer cylinder 2.

[0241] Therefore, in this invention, when it is desired to form lipstick in a shorter time and with less electrical energy, the metal mold 12A of the first structural example with less transmission delay is selected, and when it is desired to minimize deformation at the lower and upper positions of the lipstick during lipstick forming, the metal mold 12B of the second structural example is preferably selected.

[0242] In addition, regardless of Figure 11A The first structural example shown is still Figure 12A The second structural example shown, since the temperature is directly controlled by the Peltier element 3 in this invention, is similar to... Figures 14A to 16 Compared to the control method using air in the comparative experiment shown, the heating and cooling times are shorter. Therefore, the difference in deformation and characteristics between the first structural example as a bottom cooling method and the second structural example as a side cooling method is less than the difference in characteristics between bottom cooling and side cooling using air.

[0243] Here, in Figures 24A-24C The diagram shows the flow of heat in the metal mold within the independent forming units β1 to β3 of the first embodiment.

[0244] In the independent forming unit β1 of the first structural example, as Figure 24A As shown, since the metal mold 12A is in close contact with the Peltier element 3 and the rubber mold 11, heat is directly transferred from bottom to top.

[0245] In the independent forming unit β2 of the second structural example, as Figure 24B As shown, the metal mold 12B has a bottom cylindrical space 127, so that the center of the bottom of the metal mold 12B is not in contact with the Peltier element 3. Therefore, the heat rises temporarily on the outer part of the metal mold 12B and is transferred to the rubber mold 11 while expanding up and down on the inner part.

[0246] In the independent forming unit β3 of the third structural example, the lower surface of the metal mold 12C is in overall contact with the Peltier element 3, but by forming a cylindrical space 128 with a bottom on the upper side, the upper surface of the bottom of the metal mold 12C is not in contact with the rubber mold 11. Therefore, as Figure 24C As shown, heat is transferred from the metal mold 12C to the rubber mold 11 both upwards and laterally. In this structure, since there is air between the metal mold 12C and the rubber mold 11 on the lower side, in addition to... Figure 24C In addition to the arrow, heat is also slowly transferred from the bottom.

[0247] Figure 25 This is a diagram showing the results of experiments on the size of the shrinkage pores and the fragility of lipsticks formed using the independent forming units β1, β2, and β3 of the first, second, and third structural examples. Figure 25 As shown in the table, there are no problems with β1, β2, and β3 regarding shrinkage pores.

[0248] In addition, Figure 25 The table shows the hardness of the root and the breaking strength as a value representing fragility. Figure 25 The hardness of the root shown is towards the Figure 24A , Figure 24B , Figure 24C The dotted line indicates the root section, and the hardness (unit: N: Newton) is measured by inserting a hardness tester into the center of the cut surface. Additionally, the breaking strength (unit: N) represents the value (unit: N) when a force is applied laterally to the lipstick in space in a direction perpendicular to its extension direction, causing the lipstick to break.

[0249] like Figure 25 As shown, compared to structural examples β1 and β2, the lipstick formed in structural example β3 has a higher hardness at the base. Here, β2 and β3 are both structural examples of lateral cooling where heat is transferred laterally, but in β2, as... Figure 24B As shown, the contact area between the metal mold 12B and the Peltier element 3 is small at the lower end of the outer heat transfer cylinder 25, resulting in a small heat absorption effect. In contrast, the metal mold 12C of β3 is entirely connected to the Peltier element 3 via its bottom surface 122C, resulting in a high heat absorption effect. Furthermore, in the metal mold 12B of β2, the heat transferred from the outer heat transfer cylinder 25 is transferred vertically to the holding cylinder 124 and the rubber mold 11 via the upper connecting portion 126. However, in β3, as... Figure 24C As shown, the contact area of ​​side 121C, where heat is transferred from the bottom, is large, and heat is uniformly transferred from the side to the rubber mold 11 over a larger area. Based on this characteristic, it can be considered that the lipstick formed by the β3 structure has high hardness at the base.

[0250] Furthermore, although the hardness of the base of the lipstick formed by β1 and β2 is the same, their breaking strength is β1 < β2 < β3. Here, as... Figure 24A , Figure 24B , Figure 24C As indicated by the arrows, β2 and β3 represent lateral cooling where heat propagates from the sides, while β1 represents lower cooling where heat propagates from the bottom. Therefore, it can be said that even with the control of Peltier elements, lateral cooling is a breakage-resistant forming method.

[0251] <Structure of the Control Department>

[0252] Next, with Figure 26 Together, the control block of the lipstick forming apparatus 100 of the present invention will be described.

[0253] Figure 26 The controller 5 shown is a component-side control unit that can communicate with the main control unit 200 of the lipstick forming device 100.

[0254] The main control unit 200 can wirelessly or wiredly connect to the controller 5 and input information such as the product type (color, brand, etc.) of the lipsticks being manufactured, the number of lipsticks manufactured, and the temperature curve of each independent temperature control unit of each product into the input device 300 in the main control unit 200.

[0255] The main control unit 200, which serves as the main control unit, includes, in an executable manner, a conveying speed control unit 201, a pre-filling temperature control unit 202, a filling control unit 203, a post-filling temperature control unit 204, a second refrigerant circulation speed control unit 205, a control data storage unit 206, and a communication I / F (interface) 207.

[0256] The conveying speed control unit 201 adjusts the moving speed of the independent temperature adjustment unit α, which is implemented by the conveyor belt 65.

[0257] The pre-filling temperature control unit 202 adjusts the temperature of the lipstick composition in the lipstick composition filling device 101 before filling, that is, the temperature at which the lipstick composition is heated and melted and the molten lipstick composition is filled into the mold.

[0258] The filling control unit 203 adjusts the filling amount, filling speed, filling position, etc. of the lipstick composition L from the lipstick composition filling device 101 to the forming mold 1.

[0259] The temperature control unit 204 after filling adjusts the temperature of the lipstick composition in the mold 1 after filling, and the temperature of the molding conditions other than the Peltier temperature curve, such as filling the mold with the lipstick composition and then reheating it.

[0260] The control data storage unit 206 stores tables containing various set conditions, such as conveying speed, product type, number of products flowing in the production line, outside air temperature, humidity, refrigerant temperature, filling temperature, and molding temperature.

[0261] Here, in the container filling molding manufacturing apparatus 9, an external temperature sensor 98 for measuring external temperature and a humidity sensor 99 for measuring humidity may also be installed. The external temperature sensor 98 and the humidity sensor 99 are environmental sensors.

[0262] The filling temperature control unit 204 of the main control device 200 reads the table of set conditions corresponding to the outside temperature and humidity measured by the environmental sensors 98 and 99 from the control data storage unit 206 and indicates the temperature shift of the Peltier element 3 after filling.

[0263] Furthermore, the second refrigerant circulation speed control unit 205 adjusts the circulation speed of the second refrigerant W within the cooling path 71. Alternatively, a refrigerant temperature sensor 97 can be installed to measure the temperature of the first refrigerant C within the refrigerant tank 6. In this case, the second refrigerant circulation speed control unit 205 can also adjust the circulation speed of the second refrigerant W based on the temperature of the first refrigerant C within the refrigerant tank 6 detected by the refrigerant temperature sensor 97.

[0264] The communication I / F207 sends and receives data and instructions with the controller 5, which is the component-side control unit.

[0265] The controller 5, which serves as the component-side control unit, includes a communication I / F 51, a temperature control unit 52, and a heating / cooling unit 53, all of which are executable. The communication I / F 51 transmits and receives data with the main control unit 200.

[0266] Although not shown above, a Peltier element temperature sensor 39, which detects the temperature of the Peltier element 3 or a portion of the metal mold 12 in real time, may be placed near the Peltier element 3.

[0267] The temperature control unit 52 of the controller 5 can fine-tune the temperature of the Peltier element 3 based on the temperature indication from the main control device 200 and the temperature detection result of the Peltier element temperature sensor 39.

[0268] The heating and cooling unit 53 controls the temperature of the Peltier element 3 by applying a current (direction and value of the current) corresponding to the set temperature to the Peltier element 3.

[0269] With this structure, the main control unit 200 can implement temperature control after filling based on external temperature, humidity, conveying speed, and the number of products flowing in the production line. As a result, precise temperature control can be implemented, taking into account factors that affect the forming of lipsticks, thus reducing defective products and enabling high-productivity, stable, and high-quality forming that is unaffected by processing methods or the environment.

[0270] Moreover, as mentioned above Figure 4 As shown, because the molding die 1 surrounding the lipstick composition L and the outer cylinder 2 are temperature-controlled using independent Peltier elements, mutual temperature interference is minimal. Therefore, the problem of temperature difference between trial production and mass production—where low-volume production during testing leads to rapid cooling compared to testing, while high-volume production during mass production makes cooling more difficult—is almost eliminated. Thus, with such precise temperature control, the difference between trial production and mass production is small, allowing trial production conditions to be directly applied to mass production conditions.

[0271] Furthermore, since each Peltier element has its own controller 5, abnormalities can be detected immediately. Only the molded parts obtained from the individual temperature control unit α that experienced the abnormality are excluded as defective products, thus reducing the defect rate and increasing productivity. In addition, because temperature control is performed independently, a highly efficient production line structure can be achieved depending on the production volume.

[0272] In this way, by making good use of sensing and IoT technologies, we can break free from manufacturing that relies on feelings, tricks, and experience.

[0273] In addition, in this embodiment, such as Figure 4 As shown, since each forming die and the outer cylinder are separate, each of the multiple metal dies can achieve uniform temperature adjustment. Furthermore, in the above example, a structure that suppresses thermal interference of the metal dies by separately insulating them was described, but thermal interference can also be suppressed by making the outer cylinder a heat-insulating structure, as described in embodiments 9 and 10 below.

[0274] In addition, it is essential for lipsticks not to break in order to ensure quality. Therefore, it is necessary to achieve lipsticks with low wax content that do not break (i.e., high strength). Thus, by establishing a correspondence with the surrounding environment and controlling the temperature of each lipstick individually, it is possible to control deformation and crystal size, thereby forming lipsticks that are less prone to breakage.

[0275] Thus, the cosmetic forming apparatus of the present invention can independently control the temperature of the forming mold for filling the cosmetic composition, and can control the deformation and crystal size of each of the multiple forming molds and the cosmetic composition in one forming mold, regardless of the number of cosmetics being formed.

[0276] This allows for the production of lipsticks that maintain good elongation, moisturization, and color longevity by reducing the amount of wax, while also being less prone to breakage.

[0277] <Second Implementation Method>

[0278] Figure 27 This is a cross-sectional view of the independent forming unit β4 in the second embodiment. The independent forming unit β4 in this embodiment is used in a forming method based on back filling.

[0279] In the independent forming units β1 to β3 of the first embodiment described above, the outer cylinder 81 and the spiral cylinder 82 of the lipstick container are installed on the top. The outer cylinder 81 and the spiral cylinder 82 are also integrally formed with the lipstick. However, the lipstick can also be fixed, and only the lifting dish, i.e., the lifting cylinder (middle dish cylinder) 83D that rises and falls with the lipstick is used for forming.

[0280] With the lifting cylinder 83D positioned above, the lipstick composition L is filled into each recess of each forming mold 1D and the inside of each lifting cylinder 83D.

[0281] In the structure of this embodiment, on the upper side of the metal mold 12D, there is only a lifting cylinder 83D that is shorter and thinner than the spiral cylinder 82, so heat can be conducted from the heat transfer holding member 15 through the lifting cylinder 83D and the rubber mold 11D to the lipstick composition L inside the lifting cylinder 83D.

[0282] After being formed, the lipstick L and the lifting cylinder 83D are then engaged with the spiral cylinder 82 and the outer cylinder 81.

[0283] <Third Implementation Method>

[0284] Figure 28 This is a cross-sectional view of the independent forming unit β5 in the third embodiment. The independent forming unit β5 in this embodiment is used in a forming method based on back filling.

[0285] In the first and second embodiments described above, an example was described in which a rubber mold 11 was provided inside the metal mold 12 which has heat transfer properties, but it is also possible to use a forming cylinder without providing a rubber mold.

[0286] In this embodiment, each forming mold 1 is formed from a single metal mold 12E, which is a bottomed cylindrical heat transfer mold into which a rod-shaped cosmetic composition is directly filled into a cylindrical recess. In this embodiment, the inner circumferential surface of the metal mold 12E is surface-treated to prevent the cosmetic composition from adhering.

[0287] Here, if the rubber mold 11 is provided as in the first embodiment, the shape freedom of the lipstick increases. Depending on the shape of the rubber mold, convex or concave patterns such as logos and designs can be formed on the upper surface or side of the lipstick, or the shape can be made into a polygonal heart-shaped cross-section shape that is different from the cylindrical metal mold.

[0288] In contrast, in this embodiment, since no rubber mold is provided, the freedom of the lipstick's shape is reduced. However, if no pattern is needed and the inner circumferential surface of the metal mold and the shape of the formed lipstick can be the same, the number of parts can be reduced. In addition, in this structure, temperature can be directly transferred from the metal mold 12E to the lipstick composition L. Since it does not pass through the rubber mold with low thermal conductivity, the temperature response to the Peltier element can be accelerated and the molding time can be shortened.

[0289] Furthermore, in this embodiment, since no rubber mold is provided, an air hole 129 for air injection is formed on the bottom surface 122E at the lower end of the metal mold 12E in an upward and downward conductive manner. When the molded lipstick is removed from the molding mold, it is demolded by injecting air into the air hole 129.

[0290] Therefore, it is preferable to choose whether or not to use a rubber mold based on the characteristics of the formed lipstick and the requirements of its appearance design.

[0291] Furthermore, in this example, an example is described in which a lifting cylinder 83A, a spiral cylinder 82A, and an outer cylinder 81A are integrally formed on the upper side in a molding die without a rubber mold. However, the molding die of this embodiment with only a metal mold can also be applied to a structure formed integrally with only a lifting cylinder 83A on the upper side, as in the second embodiment.

[0292] Figures 29A to 29D This is a diagram illustrating the shape of a typical lipstick. Figure 29A It shows a lipstick shape resembling a cannonball. Figure 29B It shows a slender lipstick shape. Figure 29C It shows a crayon-shaped lipstick. Figure 29D This shows the shape of a lipstick with a scraper-like tip.

[0293] exist Figure 29B The slender (medium-length) type shown Figure 29C The crayon-shaped lipsticks shown generally do not require special processing on the sides or tops, and can be applied using... Figure 28 The third embodiment shown is formed without using a rubber mold.

[0294] On the other hand, Figure 29A The shell type shown Figure 29DThe top scraper type shown allows for the use of rubber molds when marking or designing the main body or top. Additionally, in... Figure 29B If you also want to apply the same decoration to the top of the slender type shown, you can also consider using a rubber mold.

[0295] Therefore, the structure with a rubber mold only at the top end will be described below as the fourth embodiment.

[0296] <Fourth Implementation>

[0297] Figure 30 This is a cross-sectional view of the independent forming unit β6 in the fourth embodiment. The independent forming unit β6 in this embodiment is used in a forming method based on back filling.

[0298] In this embodiment, the lipstick composition is filled and shaped in the discharge container with the sleeve (spiral sleeve 82F) deeply inserted. That is, in this structure, the lipstick composition is heated and cooled while it is inside the sleeve during filling and temperature adjustment. Therefore, on the independent molding unit side, the top rubber mold 16 is only provided at the lower end of the recess and its periphery.

[0299] <<Insert Fill>>

[0300] Figures 31A to 31F This is an explanatory diagram of the forming process of a rod-shaped cosmetic based on the insertion filling method of the present invention. Figure 32 This is an overall diagram of a lipstick forming device based on the insertion filling method, included in a lipstick dispensing container filling molding manufacturing apparatus.

[0301] Figures 31A to 31F It is an insertion fill method, therefore it is similar to... Figures 3A-3E Unlike the back-filling method, the lipstick is formed without attaching the outer tube 81 and the spiral tube 82 to the cosmetic material. In the insertion filling method, instead of the lifting tube 83, an insertion part 94 is inserted above the forming mold 1.

[0302] In the insertion filling method of the present invention, in the manufacturing process of the stick-shaped cosmetic, the material is heated and melted (preheated) Figure 31A ), causing the cosmetic composition to flow into the molding die ( Figure 31B ), using Peltier element 3 for reheating ( Figure 31C ) and cooling curing ( Figure 31D Afterwards, the insertion part 94 was removed while still heated. Figure 31E The outer cylinder 81, the spiral cylinder 82, and the lifting cylinder 83 are assembled in the released state. Figure 31F The formed stick-shaped cosmetic is detached from the forming mold 1 to form its shape. Figure 31G ).

[0303] exist Figures 31A to 31F In the inserted filling method shown, it is also similar to Figure 1 Unlike previous examples, during cooling and curing, temperature profiles such as cyclic cooling, quenching, or gradual cooling based on the Peltier element 3 rather than wind can be freely set.

[0304] In addition, such as Figure 32 As shown, the lipstick forming apparatus 100 of the present invention is an example of a cosmetic forming apparatus and is part of a lipstick dispensing container filling forming material manufacturing apparatus 9.

[0305] The forming process performed by the lipstick forming apparatus 100 includes a filling process and a temperature adjustment process. Therefore, the lipstick forming apparatus 100 has a lipstick composition filling device 101 and a temperature adjustment device 102.

[0306] In the filling process, the lipstick composition filling device 101 fills the forming mold 1G (refer to...) Figure 33 The liquid lipstick composition is filled (insertion filling). Furthermore, the temperature adjustment device 102 adjusts the temperature of the lipstick within the molding die 1, solidifying the lipstick composition to form a lipstick.

[0307] During insertion and filling, the forming mold assembly whose container has not been inserted is conveyed in the pre-filling conveying mechanism 91 at the front end of the lipstick forming device 100.

[0308] On the other hand, a lipstick demolding mechanism 92 and a filling and conveying mechanism 93 are provided at the rear of the lipstick forming device 100. In the lipstick demolding mechanism 92, the lipstick is removed (demolded) from the forming mold 1 that has formed the lipstick using the lipstick forming device 100.

[0309] Then, the filling conveyor 93 inserts the demolded lipstick into the discharge container for transport into the subsequent assembly process.

[0310] <Fifth Implementation>

[0311] Figure 33 This is a cross-sectional view of the independent forming unit β7 in the fifth embodiment. The independent forming unit β7 in this embodiment... Figures 31A-32 It is used in the insertion-filling type forming method described in the text.

[0312] In this embodiment, the lipstick inside is formed as a single unit, independently of the outer cylinder 81, the spiral cylinder 82 and the lifting cylinder 83.

[0313] In this embodiment, a metal mold 12G and a rubber mold 11G are present on the upper side of the lipstick L. Therefore, the total amount of lipstick composition L is filled into the recesses of each molding mold 1G.

[0314] Therefore, in this embodiment, the lipstick composition (cosmetic composition) within the forming mold 1G can conduct heat from the metal mold 12G to the upper surface and sides throughout the entire area. When forming is performed using the same metal mold with good thermal conductivity throughout the entire area via insertion filling, compared to the forming mold 1G which serves as the lipstick forming part, and as... Figure 31F As shown, even if the materials of the lifting cylinder 83 and the spiral cylinder 82 are different, the difference in thermal conductivity can suppress the occurrence of deformation.

[0315] In this way, the formed lipstick L is then inserted into the lifting cylinder 83.

[0316] <Sixth Implementation>

[0317] Figure 34 This is a cross-sectional view of the independent forming unit β8 in the sixth embodiment. In the fifth embodiment, an example of setting a rubber mold 11G in the insertion filling method was described, but a structure without a rubber mold, as in the second embodiment, can also be applied to the insertion filling method.

[0318] When forming is performed using the same metal mold 12H with good thermal conductivity in all areas without setting a rubber mold, the thermal conductivity is not different from that in cases where the forming mold 1H, the lifting cylinder 83, and the spiral cylinder 82 are made of different materials, thus suppressing the occurrence of deformation.

[0319] <<Peltier Independent Forming Unit>>

[0320] <Seventh Implementation>

[0321] Figure 35 This is a cross-sectional view of the independent forming unit γ in the seventh embodiment. In the above example, an example of setting one Peltier element relative to multiple metal molds was described, but it is also possible to set one Peltier element relative to one metal mold. The seventh embodiment is a structure in which one Peltier element is set relative to one metal mold (Peltier independent forming unit γ).

[0322] For example, it could also be like Figure 35 The structure shown depicts a Peltier element 30 disposed on the lower surface of a forming mold. In this case, if the size of the Peltier element 30 is at least the size of the metal mold 12, uniform heating and cooling are possible. Furthermore, when the Peltier elements are disposed separately, the upper limit of the Peltier element can be larger than the outer cylinder, but it is best to separate them to a degree that they do not collide with or interfere with adjacent Peltier elements.

[0323] <Eighth Implementation>

[0324] Implementation method 8 Figure 36 The independent forming unit γ1 shown is illustrated Figure 35 A variation of the Peltier element and cooling mechanism of the Peltier independent forming unit γ.

[0325] This embodiment, like the 7th embodiment, is a Peltier-independent molding unit γ1 with one Peltier element set relative to one molding die. Figure 36 In the structure, the Peltier element 30I is a bottomed cylindrical shape with cylindrical sides and bottom.

[0326] Although Figure 36 Not shown in the diagram, but in the Peltier independent forming unit γ1, a heat sink 4I for cooling each Peltier element needs to be installed for each Peltier element. In this structural example, the heat sink 4I is in a bottomed cylindrical shape that surrounds the Peltier element 30I.

[0327] As a stand-alone cooling method for radiators, for example by... Figure 36 By rotating the cooling fan 69 at the bottom, the heating and cooling processes based on the Peltier element can be carried out stably. Alternatively, it can be done as described above. Figure 4 The radiator is cooled by using one or more refrigerants or by air cooling, as shown.

[0328] <Ninth Implementation>

[0329] Implementation of the 9th embodiment Figure 37 The independent forming unit γ2 shown is Figure 36 A modified example of the Peltier element and cooling mechanism of the Peltier independent forming unit γ1.

[0330] In this embodiment, it is also possible to... Figure 37 In this case, the Peltier element 30J is only provided on the cylindrical side. The heat sink 4J is also cylindrical in shape, covering the outer periphery of the Peltier element 30J.

[0331] Furthermore, this example illustrates the use of a rubber mold within a Peltier-type independent forming unit, but a structure without a rubber mold can also be applied to this configuration. Moreover, in Figure 36 , Figure 37 The diagram shows the back filling method used in the Peltier independent type, which is integrally formed with the lifting cylinder 83A, the spiral cylinder 82A and the outer cylinder 81A. However, even in the case of the Peltier independent type, it can be formed by the back filling method or the insertion filling method, which is integrally formed with only the lifting cylinder 83.

[0332] In this example, the number of Peltier components and the number of metal molds are set in a 1:1 ratio, thus allowing for more appropriate control over each metal mold. Furthermore, if... Figure 36 , Figure 37 When the Peltier elements 30I and 30J are in contact with the side of the metal mold 12A, the transmission distance is short and the temperature is more easily transmitted, thus enabling more accurate temperature control of the lipstick.

[0333] This embodiment can form lipsticks in a minimum unit, making it suitable for small-batch manufacturing, such as limited editions or customized products with engraved names.

[0334] <Multiple integrated molding units>

[0335] In the above-described embodiments 1 to 9, as Figure 4 As shown, the outer cylinder surrounding the metal mold 12 is a series of independent and separate heat-insulating cylinders. However, if the outer cylinder is made of heat-insulating material, multiple lipsticks can also be formed as a single unit.

[0336] <10th Implementation>

[0337] Figure 38 This is a perspective view of the plurality of integral molding units δ in the 10th embodiment. Figure 391 is... Figure 38 A cross-sectional view of the plurality of integral forming units δ in the 10th embodiment.

[0338] The outer cylinder 20 of this embodiment is made of heat-insulating material, and the integrally formed outer cylinder 20 has four recesses for inserting four forming molds 1K. The heat-insulating cylinder of this embodiment, namely the outer cylinder 20, is made of heat-insulating material such as rubber, glass, inorganic fiber, wood fiber, resin, wool, etc., and preferably has a structure containing a lot of gas.

[0339] In addition, such as Figure 39 As shown, the other structures are the same as those in the first embodiment of the back filling method with a rubber mold. A rubber mold 11K, a metal mold 12K, an inner rubber retainer 13K, and an outer rubber retainer 14K are provided in each recess of the outer cylinder 20. The lipstick molded object L is integrally formed with the lifting cylinder 83, the spiral cylinder 82, and the outer cylinder 81 embedded in the upper part.

[0340] Furthermore, one Peltier element 3K is provided at the lower part of the outer cylinder 20, and the lipstick composition L in the four molding dies 1K is insulated from each other while being simultaneously temperature-adjusted.

[0341] In addition, Figure 38The diagram shows a structure using multiple one-piece molding units δ in a backfilling method, but multiple one-piece molding units δ can also be used in an insert filling method. Furthermore, in multiple one-piece molding units δ, molding can also be achieved by setting a mold without a rubber mold or a top rubber mold in the molding die. Moreover, in multiple one-piece molding units δ, the number of molding dies 1K that simultaneously adjust the temperature, i.e., the number of recesses, is not limited to four; it can also be two, three, five, or more.

[0342] <11th Implementation>

[0343] Figure 40 This is a perspective view of the plurality of integral molding units δ1 in the 11th embodiment. Figure 41 yes Figure 40 A cross-sectional view of the plurality of integral forming units δ1 in the 11th embodiment.

[0344] In the 10th embodiment, the four metal molds are integrally formed without separation, but in this embodiment, the outer cylinder 20L is provided with a separating slit 28. The other structures are the same as in the 10th embodiment.

[0345] exist Figures 37-41 In the multiple integrated units shown, the outer cylinder 20 (20L) is arranged in such a way that the multiple molding dies do not affect the temperature of the filler. Therefore, even with multiple integrated units, the temperature of the molding die for filling the cosmetic composition can be controlled independently, and temperature unevenness in each of the multiple molding dies and within a single molding die can be suppressed regardless of the number of cosmetic products being molded.

[0346] Furthermore, in all the embodiments described above, an example of using only a Peltier element for temperature control in the forming of lipstick has been illustrated, but it is also possible to combine the Peltier element with reheating based on warm air from above.

[0347] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to this specific embodiment, and various modifications and alterations can be made within the scope of the spirit of the embodiments of the present invention as described in the claims.

[0348] This international application claims priority based on Japanese Patent Application No. 2020-213983, filed on December 23, 2020, and the entire contents of No. 2020-213983 are incorporated herein by reference.
