Description

[Technical Field]

[0001] The present invention relates to a cosmetic filling system and a cosmetic filling method for filling a container with a cosmetic. [Background technology]

[0002] In the process of filling a container with cosmetics, the container is generally positioned and fixed in a predetermined location, and then the cosmetic is poured into the fixed container. A technique that is frequently used to fix the container in this injection process is a fixing technique using a container holder.

[0003] In this technique, first, a container is placed against a guide, and the container and container holder are aligned. Specifically, a recess for storing the container that matches the shape and size of the container is formed in the container holder, and the container is guided to this recess by the guide. The container is then set in the recess of the container holder and clamped by a chuck mechanism. This positions and fixes the container in a predetermined location by the container holder (see, for example, Patent Document 1).

[0004] In addition to the method of using a container holder as described above, other possible methods for fixing a container include, for example, fitting the container into a frame that corresponds to its outer shape and fixing it, directly clamping and fixing the container using a clamping mechanism, pressing down on the mouth of the container from above and fixing it using a pressing mechanism, and, in the case of filling the container with cosmetics while the container is being transported on a belt conveyor, temporarily blocking and fixing the container placed on the belt conveyor with a stopper. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2019-017854 [Patent Document 2] Japanese Patent Application Laid-Open No. 2009-006414 [Patent Document 3] Japanese Patent Publication No. 2020-205393 Summary of the Invention [Problem to be solved by the invention]

[0006] However, in the above-mentioned conventional techniques, the container holder, chuck mechanism, or other fixing mechanism or jig directly clamps the container, which often results in mechanical contact or friction between the container and the container holder, chuck mechanism, etc., which creates a risk of damaging the container.

[0007] Furthermore, when fixing a container using a container holder, it is necessary to use a container holder with a recess for accommodating the container that corresponds to the shape and size of the container, so it is necessary to prepare and adjust guides and container holders that correspond to various containers of different shapes and sizes. Furthermore, even when fixing a container without using a container holder, it is necessary to prepare jigs that correspond to fixing various containers in the fixing mechanisms such as the clamping mechanism and pressing mechanism described above, and to make various settings.

[0008] The present invention has been made to solve the above-mentioned problems, and aims to provide a cosmetic filling system and method that can safely fix containers without damaging them and that can accommodate various containers of different shapes and sizes. [Means for solving the problem]

[0009] In order to solve the above problems, the first invention is a cosmetic filling system comprising a vacuum suction device for vacuum-suctioning a cosmetic container placed on an adsorption surface, and a vibration device for vibrating the container adsorbed to the vacuum suction device, wherein the vacuum suction device is a porous chuck having a base, a porous plate whose surface serves as the adsorption surface and is arranged on the upper side of the base, and an air flow passage provided within the base, whose front opening communicates with the pores of the porous plate and whose rear opening is provided on the outer surface of the base, and the vibration device is configured to vibrate the porous chuck at a desired vibration frequency.

[0010] With this configuration, a cosmetic container can be placed on the suction surface of the porous chuck. In this state, when a suction pump is connected to the rear end opening of the air flow passage and operated, negative pressure is created inside the air flow passage. Because the pores of the porous plate are also connected to the front end opening of the air flow passage, negative pressure is also created inside the pores of the porous plate, and the container is vacuum-sucked to the suction surface and fixed to the surface of the porous plate of the porous chuck.

[0011] At this time, since only the bottom surface of the container is in contact with the surface of the porous plate, the external force applied to the container during adsorption and fixation is only applied to the bottom surface of the container, and not to other parts. Therefore, the risk of damage to the container when placing or fixing the container is extremely small. In other words, according to the present invention, the container can be fixed safely without being damaged.

[0012] The cosmetic can then be poured into the container. The vibration device can then be activated to vibrate the porous chuck. This vibration is transmitted to the container through the porous chuck. At this time, the container is firmly suction-fixed to the porous chuck, so the vibrations do not cause the container to shift position relative to the porous chuck. Therefore, the vibrations from the vibration device are transmitted to the container accurately and uniformly as desired. Furthermore, because only the bottom surface of the container is suction-fixed to the suction surface of the porous chuck, even if the vibrations from the vibration device are transmitted, the container will not collide with other elements, such as the inner wall of a conventional container holder, and the container will not be damaged.

[0013] The second invention is a cosmetic filling system according to the first invention, which is configured to have a cosmetic injection tool positioned opposite the adsorption surface at a position aligned with the central axis of the porous plate.

[0014] With this configuration, it is possible to inject the cosmetic (bulk) from the cosmetic injection device into the desired position (e.g., the center of the container) of a container placed on the adsorption surface and vacuum-fixed, thereby preventing filling defects.

[0015] The third invention is a cosmetic filling system according to the first or second invention, wherein the porous plate used in the porous chuck is configured to have countless, uniformly formed continuous pores with diameters of 0.1 μm to 1000 μm over the entire surface.

[0016] With this configuration, partial chucking, which cannot be achieved with so-called vacuum chucks that can chuck the entire chucking surface by blocking all of the holes provided on the chucking surface with the object to be chucked, i.e., chucking and fixing can be achieved by simply blocking a portion of the chucking surface with the object to be chucked (container). Therefore, according to the present invention, there is no need to prepare fixing guides or container holders to accommodate various containers of different shapes and sizes, and various containers can be handled.

[0017] The fourth invention is a cosmetic filling method for filling a container with cosmetics, which comprises the following steps: placing one or more containers on the suction surface of a porous chuck having a base, a porous plate with its surface serving as an suction surface and arranged on the upper side of the base, and an air flow passage provided within the base, the front opening of which communicates with the pores of the porous plate and the rear opening of which is provided on the outer surface of the base; a fixing step in which negative pressure is applied to the air flow passage side to vacuum-adsorb the containers to the suction surface; an injection step in which, after the fixing step, cosmetic is injected into the containers from a cosmetic injection device arranged opposite the suction surface; and a vibration step in which a vibration device vibrates the porous chuck at a desired frequency to vibrate the containers adsorbed to the porous chuck.

[0018] With this configuration, when the fixing step is performed, only the bottom surface of the container comes into contact with the surface of the porous plate, and the external force applied to the container during adsorption and fixation is only applied to the bottom surface of the container, and not to other parts. Therefore, the risk of damage to the container when placing or fixing the container is extremely low. In other words, according to the present invention, the container can be fixed safely without being damaged. Then, an injection process of injecting the cosmetic material into the container and a vibration process of vibrating the porous chuck are carried out, which allows the container into which the cosmetic material has been injected to be vibrated, preventing the container from shifting position due to the vibration and from colliding with other elements, such as the inner wall of a conventional container holder, and preventing the container from being damaged.

[0019] A fifth aspect of the present invention is the cosmetic filling method according to the fourth aspect of the present invention, wherein the cosmetic injection tool is arranged at a position that coincides with the central axis of the porous plate.

[0020] With this configuration, it is possible to inject the cosmetic (bulk) from the cosmetic injection device into the desired position (e.g., the center of the container) of a container placed on the adsorption surface and vacuum-fixed, thereby preventing filling defects.

[0021] The sixth invention is a cosmetic filling method according to the fourth or fifth invention, wherein the vibration process is performed at least while the injection process is being performed or after the injection process has been performed.

[0022] With this configuration, the vibration process is carried out simultaneously with the injection process, so that the cosmetic is injected into the container while the container is vibrated. Therefore, for example, when filling a container with a solid cosmetic that melts when heated and can maintain its shape at room temperature, even if the heated, molten cosmetic (bulk) has a high viscosity, it can be quickly filled into the container before it solidifies. [Effects of the Invention]

[0023] As described in detail above, the present invention has the excellent effect of being able to safely secure containers without damaging them and being able to accommodate a variety of containers of different shapes and sizes.

[0024] In particular, according to the fourth invention, for example, when a solid cosmetic material that melts when heated and can maintain its shape at room temperature is filled into a container, even if the heated, molten cosmetic material (bulk) has high viscosity, it can be quickly filled into the container before it solidifies, thereby preventing the occurrence of defective products.

[0026] Example 1 A cosmetic filling system according to a first embodiment of the present invention will be described below with reference to Figures 1 to 3. Figure 1 is a perspective view showing the cosmetic filling system according to the first embodiment of the present invention, Figure 2 is an exploded perspective view for explaining each device constituting the cosmetic filling system of the present invention, and Figure 3 is a schematic diagram of the cosmetic filling system showing a cross section of a porous chuck.

[0027] As shown in Figures 1 and 2, a cosmetic filling system 1 according to a first embodiment of the present invention includes a porous chuck 2 as a vacuum suction device, a vibrator 3 as a vibration device, and an injection tool 4 for injecting cosmetic material.

[0028] The porous chuck 2 is a device for vacuum-adhering a cosmetic container 100 to its adsorption surface 2a, and is composed of a base 21, a porous plate 22, and a suction pump 25, as shown in Figures 2 and 3.

[0029] The base 21 has an upwardly opening plate storage chamber 21a at its upper part, and an air flow passage 23 at its lower part.

[0030] The porous plate 22 is airtightly stored in the plate storage chamber 21a on the upper surface of the base 21, and its surface serves as the adsorption surface 2a. This porous plate 22 has countless, continuous micron-sized pores uniformly formed over its entire surface. The material and pore diameter of the porous plate 22 can be selected from those used in known porous chucks. However, to enable partial adsorption, a material with countless, uniformly formed microscopic pores of 0.1 μm to 1000 μm in size over its entire surface is preferred. In this embodiment, porous ceramics with a pore diameter of 2 μm was used as the porous plate 22. However, other materials, such as alumina or stainless steel, sintered in a breathable state, may also be used.

[0031] The air flow passage 23 is disposed below the plate storage chamber 21a, with its leading end opening 23a communicating with the plate storage chamber 21a and its rear end opening 23b communicating with the outside at the side surface of the base 21.

[0032] The suction pump 25 is a device for sucking air from inside the base 21. Specifically, the tip of the suction pipe 24 is airtightly connected to the rear end opening 23b of the air flow passage 23. That is, in this porous chuck 2, an air suction passage generated when the suction pump 25 is operated is formed by the pores of the porous plate 22, the lower part of the plate storage chamber 21a, the air flow passage 23, and the suction pipe 24 of the suction pump 25, and the sucked air is discharged from the exhaust port 25a of the suction pump 25.

[0033] Here, the function of the porous chuck 2 will be described with reference to Fig. 4 to Fig. 6. Fig. 4 is a schematic diagram for explaining the function of the porous chuck, Fig. 5 is a partial cross-sectional view for explaining partial suction by the porous chuck, and Fig. 6 is a perspective view for explaining the unique effect of the porous chuck.

[0034] As shown in Figure 4, when the container 100 is placed on the adsorption surface 2a of the porous chuck 2 and the suction pump 25 of the porous chuck 2 is operated, the air A around the container 100 is sucked into the air flow passage 23 of the base 21 through the pores of the porous plate 22 and is discharged to the outside through the suction pipe 24 and exhaust port 25a of the suction pump 25.

[0035] At this time, since the pore diameter of the porous plate 22 is as fine as 2 μm, air from pores located outside the region D directly below the container 100 does not flow into, or has difficulty flowing into, pores located within the region D, as shown in Fig. 5. As a result, the pores located within the region D directly below the container 100 are put into a vacuum state, and the container 100 is vacuum-sucked onto the suction surface 2a. That is, the porous chuck 2 has the function of partially suctioning a container 100 placed only on a partial region of the suction surface 2a of the porous plate 22, in other words, a container 100 having a smaller bottom surface than the porous plate 22.

[0036] Therefore, by using this porous chuck 2, various types of containers 100 with different shapes and sizes can be adsorbed and fixed. As a result, there is no need to prepare individual fixing guides or container holders corresponding to the shapes and sizes of the containers 100.

[0037] It is possible to suction-fix a single container 100, and also possible to suction-fix a plurality of containers 100 of the same or different types at the same time, as shown in Fig. 6. Therefore, by simultaneously carrying out the filling step described below on a plurality of containers 100 of the same or different types fixed by the porous chuck 2, it is possible to improve productivity.

[0038] 5, the container 100 is fixed by suction with only the bottom surface 101 of the container 100 in contact with the flat suction surface 2a of the porous chuck 2. This eliminates the need to fix the side surface of the container 100 using a fixing guide or holder as in the conventional method, thereby avoiding the risk of damage to the container 100 due to contact with the fixing guide or holder.

[0039] The injection device 4 is a device for injecting the cosmetic material S into the container 100, and is composed of a hopper (not shown) that dispenses a fixed amount of the cosmetic material S that has been subjected to processes such as degassing, and a nozzle that is an outlet for the cosmetic material S.

[0040] As shown in Figure 1, the injection device 4 (particularly the nozzle) is located above the porous plate 22 of the porous chuck 2, and, as an example, is positioned in a position aligned with the central axis M of the porous chuck 2 (particularly the porous plate 22) and facing the adsorption surface 2a of the porous plate 22.

[0041] On the other hand, the vibrator 3 is a device that vibrates the container 100 that is fixed by suction to the porous chuck 2. The vibrator 3 applied in this embodiment is an air or electric vibrator, and as an example, a vibrator having a piston 31 and a cylinder 32 as shown in FIG.

[0042] Specifically, the vibrator 3 is disposed directly below the porous chuck 2 and on the central axis M of the porous chuck 2 (particularly the porous plate 22) in an upward direction, and the piston 31 is fixed to the bottom surface (rear surface) of the porous chuck 2 by a connecting member 33. As a result, the reciprocating motion of the piston 31 applies stable vibrations of a desired frequency to the porous chuck 2.

[0043] In this embodiment, the vibrator 3 is configured to face upward and vibrate the porous chuck 2 in a direction perpendicular to the adsorption surface 2a, but the configuration, placement location, and vibration direction of the vibrator are arbitrary. For example, as shown by the two-dot chain lines in Figures 2 to 4 and 7, the vibrator 3 can be configured to face horizontally and vibrate the porous chuck 2 in the planar direction of the adsorption surface 2a.

[0044] The vibrator 3 may directly contact the porous chuck 2 to apply vibration to the porous chuck 2, or may indirectly contact the porous chuck 2 through a separate member to apply vibration to the porous chuck 2.

[0045] Here, the function of the vibrator 3 will be described with reference to Figures 7 and 8. Figure 7 is a schematic diagram for explaining the function of the vibrator 3, and Figure 8 is a partially enlarged view for explaining the uniform filling of the cosmetic material.

[0046] Conventionally, a method of applying vibration to the container 100 has been adopted to distribute the cosmetic material (bulk) injected into the container 100 throughout the container 100, especially when filling a cosmetic material (bulk) with a high viscosity that creates sharp corners. This method typically involves preparing a holder with a storage compartment slightly larger than the outer shape of the container 100, and then applying vibration to the holder itself while the container 100 is stored in the storage compartment. However, with this method, when filling cosmetic material (bulk) into containers 100 of different shapes and sizes, it is necessary to prepare a holder that matches the shape and size of the container 100 each time. Furthermore, during the vibration, the outer wall of the container 100 may collide with the inner wall of the holder, which may prevent the intended vibration from being transmitted to the container 100, or it may be necessary to adjust the method of application of vibration so that the intended vibration is transmitted to the container 100 effectively. Furthermore, there is a risk that the container 100 may be damaged if the outer wall of the container 100 collide with the inner wall of the holder during the vibration. On the other hand, if vibration is applied to the mounting portion of the container 100 without fixing it using a guide or holder, the vibration will change the mounting position of the container 100, causing it to deviate from the position where the cosmetic injection device is positioned, making it impossible to inject the cosmetic into the intended position of the container 100 (for example, the center of the container 100), which can easily result in poor filling.

[0047] 7, the container 100 does not use any guide or holder for fixing, and only the bottom surface of the container 100 is firmly sucked and fixed by the porous chuck 2. When the vibrator 3 is operated with the container 100 sucked to the porous chuck 2, the porous chuck 2 vibrates, and the container 100 also vibrates integrally with the porous chuck 2, so that the container 100 does not become displaced relative to the porous chuck 2.

[0048] Therefore, if the container 100 is fixed by suction at a desired position (for example, the center) on the suction surface 2a of the porous chuck 2, the container 100 will not deviate from its fixed position on the suction surface 2a of the porous chuck 2 even if it is subjected to vibration by the vibrator 3 as described above. The injection tool 4 (particularly the nozzle) for the cosmetic material S (bulk) is positioned opposite the suction surface 2a at a position aligned with the central axis M, so that the cosmetic material S (bulk) can always be injected from the injection tool 4 into the intended position on the container 100 (in this case, the center of the container 100), preventing improper filling.

[0049] Furthermore, since only the bottom surface of the container 100 is fixed by suction to the porous chuck 2 (particularly the suction surface 2a), even if vibration is applied to the container 100, it will not collide with the holder as in the conventional case, and the risk of damage to the container 100 can be avoided.

[0050] 8, when the cosmetic S is injected from the injection tool 4 into the container 100, the surface of the cosmetic S may become heaped (or angular) in the container 100 immediately after injection, as shown by the dashed-dotted line, or the cosmetic S may not reach every corner of the container 100, especially if the viscosity of the cosmetic S is high. After a certain amount of time has passed, the surface of the cosmetic S may naturally become uniform as shown by the dashed-dotted line, or the cosmetic S may reach every corner of the container 100. Here, by vibrating the container 100 using the vibrator 3, fast and reliable filling can be achieved, i.e., the surface of the cosmetic S in the container 100 can be made uniform and the cosmetic S can reach every corner of the container 100. The vibration by the vibrator 3 may be performed at least one of before the injection of the cosmetic S begins, during the injection of the cosmetic S, and after the injection of the cosmetic S is completed. In particular, by vibrating the container 100 at least at the start of pouring the cosmetic material S, it is possible to more quickly and reliably fill the cosmetic material S. Therefore, particularly when filling a highly viscous cosmetic material S that has a short solidification time, solidification will begin immediately after pouring, but by simultaneously pouring and vibrating as described above, the cosmetic material S can be filled into the container 100 quickly, uniformly, and reliably before it solidifies.

[0051] 7, the injection device 4 and the container 100 are positioned so that the centers of the injection device 4 and the container 100 are aligned on the central axis M of the porous chuck 2. However, the positioning of the container 100 is not limited to this. That is, the container 100 does not necessarily have to be positioned so that the nozzle of the injection device 4 faces the center of the container 100. For example, when the shape of the container 100 is circular, elliptical, square, or rectangular in plan view, positioning the injection device 4 relative to the center of the container 100 and filling the container 100 improves filling accuracy, as described above. However, when filling an irregularly shaped container 100, the cosmetic material S may be more accurately filled into the container 100 if the nozzle of the injection device 4 is positioned at a position offset from the center of the container 100. Therefore, the positional relationship between the nozzle of the injection device 4 and the container 100 is arbitrary and can be set so that the cosmetic material S can be injected into the desired position in the container 100.

[0052] Example 2 Next, a cosmetic filling method according to a second embodiment of the present invention will be described with reference to Fig. 9. Fig. 9 is a flow chart showing the cosmetic filling method according to the second embodiment of the present invention.

[0053] The cosmetic filling method of this embodiment is realized by the cosmetic filling system 1 of the first embodiment.

[0054] As shown in Fig. 9, in the cosmetic filling method of this embodiment, first, a placement step is performed (step S1 in Fig. 9). That is, as shown in Figs. 1 and 3, the container 100 is placed on the suction surface 2a of the porous chuck 2 and positioned on the central axis M where the center of the porous chuck 2 (particularly the suction surface 2a) and the center of the injection tool 4 (particularly the nozzle tip) for the cosmetic S (bulk) coincide with each other.

[0055] After the placement step is completed, the fixing step is executed (YES in step S2, S3 in FIG. 9). That is, as shown in FIG. 4, the suction pump 25 is operated to create a negative pressure on the air flow passage 23 side of the porous chuck 2, and the container 100 is adsorbed onto the adsorption surface 2a.

[0056] Next, it is determined whether or not to simultaneously execute the injection step and the vibration step (step S4 in FIG. 9). This can be determined mainly depending on the properties of the cosmetic (bulk), but as an example, the cosmetic filling method of this embodiment will be described assuming that the injection step and the vibration step are simultaneously executed (YES in step S4, S5 in FIG. 9).

[0057] Note that executing the injection process and the vibration process simultaneously includes cases where the injection process and the vibration process are started at the same time, but it also includes cases where the vibration process is started before the injection process is started, as long as the vibration process is executed while the injection process is being executed.

[0058] In the injection step, as shown in FIG. 7, the cosmetic material S is injected into the container 100 from an injection tool 4 disposed directly above the container 100 and on the central axis M.

[0059] Various cosmetics can be used in accordance with the present invention, examples of which include lipstick, lip gloss, lip balm, concealer, foundation, eye color, cheek color, etc., including various solid cosmetics that are melted when heated and can maintain their shape at room temperature. When such solid cosmetics are used, in the injection step, the cosmetic S, which is a bulk solid cosmetic that has been heated to a predetermined temperature and melted in a fluid state, is placed in a hopper (not shown) after being subjected to a process such as degassing, and this cosmetic S is injected into the container 100 through the injection device 4 (particularly the nozzle) in fixed amounts, for example, in amounts corresponding to the capacity of the container 100. In order to maintain the fluid state of the cosmetic S, the hopper and injection device 4 have heating means that can heat the cosmetic S to a predetermined temperature.

[0060] In the vibration process, the vibrator 3 is operated to reciprocate the piston 31 fixed to the porous chuck 2, and stable vibrations of a desired frequency are transmitted to the container 100 through the porous chuck 2.

[0061] In particular, when filling a highly viscous cosmetic material S that has a short solidification time, solidification will begin immediately after filling. However, by simultaneously carrying out the injection process and the vibration process as described above, the cosmetic material S can be filled into the container 100 quickly, uniformly, and reliably before the cosmetic material S solidifies.

[0062] If the cosmetic S does not require or is not suitable for simultaneous execution of the injection step and the vibration step, the vibration step can be executed after the injection step (NO in step S4, S6, S7 in FIG. 9). This also enables the cosmetic S to be quickly and reliably filled into the container 100.

[0063] The vibration step continues until the cosmetic material S is uniformly filled in the container 100 (NO in step S8 in FIG. 9). Specifically, the vibration step may be continued until a predetermined time has elapsed that is sufficient for the cosmetic material S to be uniformly filled in the container 100, the time being determined in advance depending on the properties of the cosmetic material S, such as viscosity, and the size and shape of the container 100.

[0064] When the cosmetic material S has been uniformly filled into the container 100, the execution of the vibration step is stopped and the cosmetic material filling method is ended (YES in step S8 of FIG. 9).

[0065] Cosmetics according to the present invention are not limited to the solid cosmetics described above, but also include gel-, jelly-, and cream-like cosmetics. While such gel-like cosmetics often require heating to be avoided or only heated at low temperatures to prevent sensory changes and evaporation of cosmetic ingredients, the present invention can achieve the following effects without heating the cosmetics when filling them. For example, even when filling a rectangular container or a container with a shoulder where the container neck is smaller in diameter than the container body, the cosmetics can be distributed evenly to the corners and shoulders inside the container, preventing voids from forming. Furthermore, the vibration process can raise air bubbles generated by the injection of the cosmetics to the liquid surface and pop them, preventing air bubbles from being mixed in. Furthermore, even if the cosmetics dispensed from the nozzle of the injection device 4 become angular due to being pulled by the nozzle at the end of dispensing, the vibration process can smooth and even the surface of the cosmetics.

[0066] The other configurations, actions and effects are the same as those of the first embodiment, and therefore the description thereof will be omitted.

[0067] The present invention is not limited to the above-described embodiment, and various modifications and changes are possible within the scope of the gist of the invention.

[0068] For example, in the above embodiment, a container 100 having a bottom surface smaller than the porous plate 22 of the porous chuck 2 is adsorbed (partially adsorbed) and the cosmetic material S is filled into this container 100. However, it is of course also possible to adsorb (fully adsorb) a container 100 having a bottom surface equal to or larger than the porous plate 22 and fill the cosmetic material S into this larger container 100.
