Summary of the Invention

Problems to be Solved by the Invention

[0004] However, although the invention described in Cited Document 1 complicates the merging of the first composition and the second composition by dividing the first composition into a plurality and supplying it to the merging section, and efficiently merges each composition, the structures of the subsequent mixing section and nozzle section are the same as those of the prior art, and there is a problem that it is impossible to fill a multi-color cosmetic having a beautifully marbled pattern with sufficient color mixing.

[0005] An object of the present invention is to provide a filling device for multi-color cosmetics that can fill a multi-color cosmetic having a beautifully marbled pattern with sufficient color mixing. [Means for solving the problem]

[0006] The multi-color cosmetic filling apparatus of the present invention is a multi-color cosmetic filling apparatus for filling a plurality of colored cosmetic products that have fluidity, and is characterized by comprising: a first supply channel for supplying a first cosmetic product; a second supply channel for supplying a second cosmetic product of a different color from the first cosmetic product; a merging means for merging the first cosmetic product and the second cosmetic product supplied through the first supply channel and the second supply channel to form a combined cosmetic product; a cylindrical discharge means for discharging the combined cosmetic product merged by the merging means; and a regulating means provided inside the discharge means for regulating the flow of the combined cosmetic product.

[0007] With this configuration, the regulating means is provided inside the dispensing means and regulates the flow of the combined cosmetic, making it difficult for the combined cosmetic to be dispensed from the dispensing means. Consequently, it can be retained when the first cosmetic and the second cosmetic are combined in the combining means, making it easier to mix the first and second cosmetic. Therefore, the multi-color cosmetic filling device can fill the multi-color cosmetic having a beautiful marble-like pattern that is well mixed.

[0008] In the present invention, the regulating means is preferably a shaft inserted inside the dispensing means.

[0009] With this configuration, since the regulating means is a shaft inserted into the dispensing means, the first and second cosmetic can be easily mixed simply by inserting the shaft into the dispensing means of a conventional multi-color cosmetic filling device, and a multi-color cosmetic with a beautiful marble-like pattern that is well mixed can be filled without designing a new multi-color cosmetic filling device. Here, the shaft may be columnar or cylindrical. If a columnar shaft is used as the shaft of the dispensing means, if the shaft is shaped to create a gap inside the dispensing means when the shaft is inserted inside the dispensing means, the combined cosmetic can be dispensed using this gap as a new flow path. Also, if a cylindrical shaft is used as the shaft of the dispensing means, the combined cosmetic can be dispensed using the inside of the shaft as a new flow path.

[0010] In the present invention, it is preferable that the shaft is formed in the shape of a cylindrical shaft having an outer surface that fits with the inner surface of a cylindrical discharge means, and that it has a groove formed on the outer surface from the base end to the tip.

[0011] With this configuration, the shaft is formed in the shape of a cylindrical shaft having an outer surface that fits with the inner surface of the cylindrical dispensing means, and has a groove formed on its outer surface from the base to the tip. As a result, the dispensing means can dispense the combined cosmetic through the gap formed by the inner surface of the dispensing means and the groove of the shaft, which serves as a new flow path. Since this new flow path is eccentric with respect to the central axis of the dispensing means, the multi-color cosmetic filling device can fill the multi-color cosmetic with a beautiful marble-like pattern that is well mixed, resulting in a design completely different from the conventional nozzle part described in Patent Document 1, which dispenses the combined cosmetic.

[0012] In the present invention, it is preferable that the groove portion be formed in a drill shape.

[0013] With this configuration, the groove is formed in a drill shape, so when the dispensing means dispenses the combined cosmetic using the gap formed by the inner circumferential surface of the dispensing means and the groove of the shaft as a new flow path, the combined cosmetic can be dispensed in a spiral shape along the axial direction. Therefore, the multi-color cosmetic filling device can fill the multi-color cosmetic having a spiral pattern and a beautiful marble-like pattern that is well mixed.

[Figure 2] Diagram showing the nozzle unit in a disassembled state. [Figure 3] Diagram showing the assembled state of each unit of the nozzle. [Figure 4] Partial cross-sectional view showing the cross-section of the merging unit and discharge unit in the assembled state of each nozzle unit. [Figure 5] A diagram showing the flow paths of multiple colored cosmetics that have fluidity. [Modes for carrying out the invention]

[0015] Figure 1 is a perspective view showing a multi-color cosmetic filling apparatus according to one embodiment of the present invention. In Figure 1, the vertically upward direction is defined as the +Z axis, and the two axes perpendicular to this Z axis are described as the X and Y axes. The same applies to the following drawings.

[0016] As shown in Figure 1, Nozzle 1, a filling device for multi-colored cosmetics, is a device for filling with multi-colored cosmetics that have fluidity. This Nozzle 1 comprises a supply unit 2 that supplies multi-colored cosmetics that have fluidity, a merging unit 3 attached to the -Z-axis side of the supply unit 2 and which merges the multi-colored cosmetics that have fluidity to form a merging cosmetic CC, and a discharge unit 4 attached to the -Z-axis side of the merging unit 3 and which discharges the merging cosmetic CC merged in the merging unit 3 into a bottomed cylindrical container 10.

[0017] The supply unit 2 includes three supply paths 21 that supply a cosmetic with fluidity, and a cylindrical support 22 that supports each supply path 21. Each supply path 21 is arranged at equal intervals in a triangular shape, and supplies cosmetics with fluidity of different colors supplied from a pump (not shown) via a tube T. In the present embodiment, the first cosmetic having the first color is divided and supplied to two supply paths 21, and the second cosmetic having the second color different from the first color is supplied to the other one supply path 21.

[0018] Here, the cosmetics of different colors refer to cosmetics whose differences can be distinguished based on human vision. It includes not only cosmetics with different lightness, chroma, and hue, but also cosmetics with the same color but different glossiness, such as those with pearls added and those without.

[0019] Here, the multi-colored cosmetics supplied via the tube T are oil-based solid cosmetics containing an oily component. Specifically, the oil-based solid cosmetics are those obtained by blending pigments and the like as necessary with solid fats such as candelilla wax and liquid oils such as hydrocarbons. This oil-based solid cosmetic has good affinity for the skin and is used in makeup cosmetics such as gloss, lipstick, eyeshadow, eyeliner, and oil-based foundation. Also, its dosage forms include various forms such as solid, liquid, paste, and emulsion. In the present embodiment, the oil-based solid cosmetic has a solidity that can maintain its shape at normal temperature, but is adopted to melt and generate fluidity when heated to 70 °C or higher (more preferably 75 °C or higher).

[0020] Thus, in the present embodiment, each supply path 21 functions as a first supply path that supplies the first cosmetic and a second supply path that supplies the second cosmetic having a color different from the first cosmetic. In addition, in this embodiment, the supply unit 2 includes three supply paths 21, but it may also have two or four or more. In short, the multi-color cosmetic filling device only needs to include a first supply path and a second supply path. Also, in this embodiment, the first cosmetic is divided and supplied to two supply paths 21, but it may also be supplied to the supply paths 21 without being divided, or three cosmetics of different colors may be supplied to each of the three supply paths 21. In short, the first supply path only needs to supply the first cosmetic, and the second supply path only needs to supply the second cosmetic of a color different from the first cosmetic.

[0021] FIG. 2 is a diagram showing a state in which each unit of the nozzle is disassembled. As shown in FIG. 2(a), the support 22 includes a main body portion 23 that supports each supply path 21, and a male screw portion 24 that supports each supply path 21 and extends from the main body portion 23 toward the -Z axis direction side.

[0022] The confluence unit 3 is a unit formed in a substantially cylindrical shape as a whole, and includes a female screw portion 31 formed at the end on the +Z axis direction side, a female screw portion 32 formed at the end on the -Z axis direction side, and a confluence portion 33 as a confluence means formed between the female screw portions 31 and 32 . The confluence portion 33 is a part where the first cosmetic and the second cosmetic supplied through the first supply path and the second supply path are confluent to form a confluent cosmetic CC. As shown in FIGS. 2(b) and 2(c), this confluence portion 33 has three semi-disk-shaped partition plates 34. Of each partition plate 34, the partition plate 34 located on the supply unit 2 side and the partition plate 34 located on the discharge unit 4 side are formed in a semi-disk shape that partitions the region on the +Y axis direction side as shown in FIG. 2(b), and the partition plate 34 located in the center is formed in a semi-disk shape that partitions the region on the -Y axis direction side as shown in FIG. 2(c). In this embodiment, the confluence section 33 was equipped with a partition plate 34, but it may be equipped with other structures such as a static mixer instead of the partition plate 34, or it may not be equipped with such structures at all. In short, the confluence means only needs to be able to combine multiple colored cosmetics that have fluidity to form a combined cosmetic.

[0023] As shown in Figure 2(a), the discharge unit 4 is a unit formed in a substantially cylindrical shape overall, and has a circular through-hole in its interior, functioning as a discharge means for discharging the combined cosmetic CC that has been combined in the confluence unit 3. This discharge unit 4 comprises a main body portion 41 with a hexagonal cross-section, a male screw portion 42 extending from the main body portion 41 toward the +Z axis direction, and a cylindrical discharge portion 43 extending from the main body portion 41 toward the -Z axis direction.

[0024] Furthermore, the nozzle 1 includes a shaft 5 that is inserted into the discharge unit 4. This shaft 5 is formed in the shape of a cylindrical shaft having an outer surface that fits with the inner surface of the discharge unit 4. Furthermore, this shaft 5 is formed in a drill shape. In other words, the shaft 5 has a groove formed on its outer surface from the base end to the tip.

[0025] Figure 3 shows the assembled state of each unit of the nozzle. As shown in Figure 3, nozzle 1 can be assembled by screwing the male threaded portion 24 of supply unit 2 and the female threaded portion 31 of merging unit 3 together, and screwing the female threaded portion 32 of merging unit 3 and the male threaded portion 42 of discharge unit 4 together.

[0026] Figure 4 is a partial cross-sectional view showing the merging unit and discharge unit in their assembled state. As shown in Figure 4, the discharge unit 4 is equipped with a stopper 44 provided at the end on the -Z axis side of its inner circumferential surface. This stopper 44 is fixed to the discharge unit 4 by welding a metal piece, and prevents the shaft body 5 from falling off. By assembling the nozzle 1, each supply passage 21 of the supply unit 2, the junction section 33 of the junction unit 3, and the through-hole of the discharge unit 4 will be in communication with each other.

[0027] Figure 5 shows the flow channels for multiple colored cosmetics that have fluidity. The first cosmetic and the second cosmetic supplied through each supply channel 21 flow into the confluence section 33, as shown in Figure 5 (arrow A in the figure). As mentioned above, the confluence section 33 has three semi-circular partition plates 34. Therefore, the first cosmetic and the second cosmetic merge at the confluence section 33 to become the combined cosmetic CC (arrow B in the figure), and then, while meandering to avoid each partition plate 34, they are mixed and reach the discharge unit 4. As described above, the discharge unit 4 has a shaft 5 inserted inside it, so the gap formed by the inner circumferential surface of the discharge unit 4 and the groove of the shaft 5 can be used as a new flow path to discharge the combined cosmetic CC (arrow C in the figure). Thus, the shaft 5 is installed inside the dispensing unit 4 and functions as a regulatory means for regulating the flow of the combined cosmetic CC.

[0028] According to this embodiment, the following actions and effects can be achieved. (1) The shaft 5 is installed inside the discharge unit 4 and restricts the flow of the combined cosmetic CC, so that the combined cosmetic CC is less likely to be discharged from the discharge unit 4, and as a result it can be retained when the first cosmetic and the second cosmetic are combined at the confluence section 33, making it easier to mix the first cosmetic and the second cosmetic. Therefore, the nozzle 1 can be filled with a multi-color cosmetic having a beautiful marble-like pattern that has been thoroughly mixed.

[0029] (2) The shaft 5 can be inserted into the discharge unit 4 of a conventional multi-color cosmetic filling device to facilitate the mixing of the first cosmetic and the second cosmetic, and a multi-color cosmetic with a beautiful marble-like pattern that is well mixed can be filled without designing a new multi-color cosmetic filling device.

[0030] (3) The shaft 5 is formed in the shape of a cylindrical shaft having an outer surface that fits with the inner surface of the cylindrical discharge unit 4, and has a groove formed on its outer surface from the base to the tip. Therefore, the discharge unit 4 can discharge the combined cosmetic CC using the gap formed by the inner surface of the discharge unit 4 and the groove of the shaft 5 as a new flow path. Since this new flow path is eccentric with respect to the central axis of the discharge unit 4, the nozzle 1 can be filled with a multi-color cosmetic having a beautiful marble-like pattern that is well mixed, which is a completely different design from when the combined cosmetic CC is discharged with a conventional nozzle part described in Patent Document 1.

[0031] (4) Since the groove is formed in a drill shape, when the discharge unit 4 discharges the combined cosmetic CC using the gap formed by the inner circumferential surface of the discharge unit 4 and the groove of the shaft 5 as a new flow path, the combined cosmetic CC can be discharged in a spiral shape along the axial direction. Therefore, the nozzle 1 can be filled with a multi-color cosmetic having a spiral pattern and a beautiful marble-like pattern that is well mixed.

[0032] Furthermore, the present invention is not limited to the embodiments described above, and any modifications, improvements, etc., that can achieve the objectives of the present invention are included within the scope of the present invention. For example, in the above embodiment, the multi-colored cosmetic was an oily solid cosmetic containing an oily component, but any cosmetic that has fluidity may be used. For example, it may be a slurry-like cosmetic obtained by mixing a cosmetic base of a solid powder cosmetic such as foundation, face powder, or eyeshadow with a volatile solvent such as ethanol, water, liquid paraffin, isoparaffin, or isopropyl alcohol.

[0033] Furthermore, although the groove was formed in a drill shape in the above embodiment, it may also be formed in a straight line or in other shapes such as an arc. In short, the groove only needs to be formed on the outer surface of the shaft from the base end to the tip.

[0034] Furthermore, in the above embodiment, the shaft 5 was formed in the shape of a cylindrical shaft having an outer surface that fits with the inner surface of the discharge unit 4. In contrast, the shaft can have any shape as long as it can be inserted into the discharge means, and it can be columnar, cylindrical, or not have a circular cross-section. For example, if a columnar shaft is used as the dispensing means, then by using a shaft with a shape that allows a gap to be formed inside the dispensing means when the shaft is inserted inside the dispensing means (a shaft with a cross-sectional area smaller than the cross-sectional area of ​​the through-hole of the dispensing means), the combined cosmetic can be dispensed using this gap as a new flow path. Furthermore, for example, if the dispensing means employs a cylindrical shaft (a shaft having the same cross-sectional shape as the through-hole of the dispensing means, with a through-hole formed therein), the confluence cosmetic can be dispensed through the inside of the shaft, which serves as a new flow path. In this case, the through-hole of the shaft may be eccentric with respect to the central axis of the through-hole of the dispensing means.

[0035] Furthermore, in the above embodiment, the regulating means was a shaft 5 inserted into the discharge unit 4, but it may also be a protruding part formed inside the discharge means. In short, the regulating means only needs to be provided inside the discharge means and capable of regulating the flow of the combined cosmetic. [Industrial applicability]
