Description

Technical Field [0001] The present invention relates to an apparatus for manufacturing a cosmetic composition containing multiple instantaneous emulsified formulations based on a microfluidic channel,

The present invention relates to an apparatus for manufacturing a cosmetic composition for discharging a plurality of external formulations prepared by moving an external fluid and an internal fluid along a microfluidic channel to instantaneously emulsify the fluid, A plurality of emulsified particles in which the outermost fluid surrounds the outer surface of the emulsified particles by making the emulsified material produced by the momentary emulsification method using the special fluid behavior characteristics of the outermost fluid meet with the outermost fluid in a manner of instantaneous emulsification To a cosmetic composition production apparatus.

In general, the technique of emulsifying a fluid means a technique of dispersing one of two fluids, which do not mix with each other like water and oil, into small particles and dispersing them in a stable state in another liquid. In the field of cosmetics, emulsifying technology has been widely applied to lotions, creams, essences, massage creams, cleansing creams, makeup bases, foundations, eyeliners, and mascara. That is, in order to manufacture the above-described cosmetics, it is preferable to prepare oil-in-water (O / W) emulsified particles by uniformly dispersing a hydrophobic fluid such as oil in a hydrophilic fluid such as water in a small particle state, W / O (Water in Oil) emulsified particles are produced by uniformly dispersing the particles in a small particle state. Such O / W emulsion particles and W / O emulsion particles are called emulsions or emulsions.

In order to produce such an emulsified material, an emulsified material using a hydrophilic fluid and a hydrophobic fluid was prepared by a physical method. For example, as disclosed in Korean Patent Publication No. 10-0222000, conventionally, after a hydrophilic fluid and a hydrophobic fluid are both poured into a huge container, a stirrer is operated to disperse particles of another fluid to one fluid. For example, a homomixer or a microfluidizer is used as the stirrer. In other words, O / W emulsified particles or W / O emulsified particles were prepared by pouring a hydrophilic fluid and a hydrophobic fluid in a large vessel and then mixing the fluids with each other using a stirrer. The above work can be called oil painting work.

In addition to the above operations, by introducing the surfactant into the container, the interface energy between the hydrophilic fluid and the hydrophobic fluid is lowered to easily form an emulsion such as O / W emulsified particles or W / O emulsified particles, Thereby preventing aggregation of emulsified particles. Specifically, even if an emulsion such as O / W emulsified particles or W / O emulsified particles is formed by the operation of the stirrer, if the operation of the stirrer is stopped and a certain period of time is elapsed, the emulsion is united and the hydrophilic fluid and the hydrophobic fluid are separated . In order to prevent this phenomenon, that is, the surfactant is injected so that the emulsified tiny particles are stable and maintain the emulsion state for a long period of time.

The emulsified particles thus completed through the emulsification process are transferred to a container containing a hydrophilic fluid or a hydrophobic fluid, whereby the emulsified particles having completed the emulsification operation are emulsified again.

For example, W / O emulsified particles prepared through emulsification may be injected into a container containing a hydrophilic fluid, and the W / O / W emulsified particles may be produced through a secondary stirring operation. That is, the hydrophilic fluid covers the outer surface of the W / O emulsified particles, so that the W / O / W emulsified particles of multiple formulations can be produced. Similarly, O / W emulsified particles prepared through emulsification may be injected into a container containing a hydrophobic fluid, and O / W / O emulsified particles may be produced through a secondary stirring operation. That is, the O / W / O emulsified particles, which are multiple formulations (multiple emulsions), can be produced by covering the outer surface of the O / W emulsified particles with the hydrophobic fluid.

Such multiple formulations are materials having a structure in which emulsifying materials are dispersed in emulsified materials, and dispersed particles are dispersed as smaller particles than emulsified particles produced through emulsification operations. These multiple formulations are advantageous in that they have both the moisturizing effect of the W / O emulsified particles and the fresh sensation of the O / W emulsified particles, and are located at the outermost positions (W / O / W or O / W / O) From the sense of use of the formulation to the feeling of use of the innermost emulsified particles, the inlaid feel can be felt sequentially.

However, according to the above conventional art, after the production of the W / O emulsified particles or the O / W emulsified particles, the produced emulsified particles are poured into a container containing a hydrophilic fluid or a hydrophobic fluid to complete the multiple formulations, The complicated and manufactured formulations also have a problem in that the emulsion particles are unstable and it is difficult to obtain a stabilized formulation in the long term because the first step does not include the emulsification step to facilitate formation of emulsified particles during the second emulsification.

That is, when manufacturing a cosmetic composition, since a large amount of multiple formulations are manufactured in advance and the manufactured product must be sold in accordance with the user's demand, a long period of time is created between the production time of the multiple formulations and the actual use time of the user .

In addition, when a large number of multiple formulations are stored for a long period of time, there is a problem in that various restrictions are caused in manufacturing, packaging, transportation, etc. in consideration of long-term stability of the product.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Although the present invention has been described with reference to the embodiments shown in the drawings, it is to be understood that the technical idea of the present invention and its essential structure and action are not limited by this embodiment.

FIG. 2 is a plan view showing a configuration of a first channel among the fluid channels of the apparatus. FIGS. 3A and 3B are views showing a state in which O / W emulsion particles or W / O emulsion particles are formed through the first channel Sectional view of the emulsified material.

Referring to the drawings, an apparatus 1 for manufacturing a cosmetic composition according to the present invention is formed by a housing 10 in its outer shape. At one side of the housing 10, a pump 70 which can be operated by the user can be provided, and the user can discharge the substances in the housing 10 to the outside by pressing the pump 70. For example, when the user presses the pump 70, the pressure of the moving path of the substances in the housing 10 becomes high. In this state, when the user releases the pressure of the pump 70, negative pressure is applied to the movement path of the substances, thereby discharging the substances to the outside.

The pump 70 is a means for supplying energy for discharging the fluid from the containers 21, 22 and 45 to instantaneously emulsify the fluid and discharging the fluid through the discharge port formed on the outer side of the housing 10, An operating portion which can be operated by a user is exposed to the outside of the housing 10 and a connecting portion for discharging the mixed liquid to the outside can be provided inside the housing 10. [ The raw material contained in the outer container 21, the inner container 22 and the outermost container 45 is supplied to the fluid channel 100 by the pressure formed by the pump 70 and flows into the fluid channel 100 The supplied raw materials move along a predetermined path and are instantaneously emulsified and then discharged to the pump 70 through the tube 60. To this end, a series of flow paths communicating with each other from the pump 70 to the respective containers 21, 22, 45 can be formed.

In the present embodiment, the pump 70 is configured to include a discharge unit that is exposed to the outside of the housing 10 to discharge cosmetics, but this is merely an example, and the spirit of the present invention is not limited thereto. For example, the discharge portion is provided separately from the pump 70, and the pump 70 may be connected to any point in the series of flow paths from the vessels 21, 22, 45 to the discharge portion to provide pressure have.

In this embodiment, the pump 70 is shown as an example of a push-type pump for allowing a negative pressure to be applied to the movement path of the fluids in the housing 10 by the user pressing and releasing the operating portion. In this case, the raw material discharge from the containers 21, 22 and 45, the movement in the fluid channel 100, and the discharge of the cosmetic material are both realized by the pressure in the single direction formed by the pump 70 There is an advantage that the configuration of the apparatus can be simplified.

However, the idea of the present invention is not limited to this, and various types of pumps may be used as the pump 70. [ For example, the non-powered pump may be a button-spring pump, a syringe pump, a flexible tube pump, a gear pump, a porous pump, a thread inserting pump, etc. Or a pump for absorbing or discharging the fluid by capillary action by applying an orifice, a rollerball, a pencil, or the like to the discharge port can be applied. As the power pump, a pump that controls electricity, vibration, sound waves, and a piezoelectric material to absorb or discharge fluid may be applied.

The housing (10) is provided with a container (21) for receiving an external fluid and an internal container (22) for housing an internal fluid. Here, the extracellular fluid may be either an oil phase or an aqueous phase, and the inner fluid may be an oil phase, an aqueous phase, or a gaseous phase. For example, the outer container 21 and the inner container 22 may be provided inside the housing 10 to form one fluid storage portion 20. Specifically, a shielding film 23 extending in the up-and-down direction and separating the inner space of the fluid accommodating portion 20 is provided at the center of the fluid accommodating portion 20. On one side of the shielding film 23, an external-phase fluid is received to form the external-phase container 21, and on the other side, an internal-phase fluid is accommodated to form an internal-

In addition, the housing 10 is provided with an outermost container 45 that receives the outermost fluid, which is in contact with the emulsified material formed by the inward fluid and the outermost fluid, and forms a multiple formulation. For example, the outermost container 45 may be installed separately from the fluid accommodating portion 20 inside the housing 10. At this time, the outermost fluid may have a similar range or substantially the same hydrophilicity as the inner fluid. For example, when the outermost fluid is in contact with the emulsified material to form multiple formulations, the outermost fluid and the inland fluid are mixed with each other so that both the moisturizing effect of the W / O emulsified particles and the fresh feel of the O / And may have the same corresponding parental number. That is, when the inner fluid is oil-in-water, the outermost fluid may be oil-in-water. However, the spirit of the present invention is not limited thereto, and the inner fluid and the outermost fluid can be combined in various forms as needed.

The outer container (21) and the inner container (22) are respectively connected to an outer fluid infusion pipe (30) and an inner fluid infusion pipe (40), which are movement paths of the inner and outer fluid stored therein. That is, the contaminant fluid contained in the container 21 can be discharged to the outside of the container 21 along the container 30. Similarly, the inner fluid contained in the inner container 22 may be discharged out of the inner container 22 along the inner fluid injection pipe 40.

In addition, the outermost container 45 is connected to the outermost fluid injection pipe 46, which is the path of the outermost fluid stored therein. That is, the outermost phase fluid contained in the most outer phase vessel 45 can be discharged out of the most outer phase vessel 45 along the outermost phase fluid injection pipe 46. Here, the outermost fluid may be either oil or water.

In this case, when the pressure is applied to the connecting portions of the containers 21, 22, 45 and the flow paths 30, 40, 46, Means may be provided.

In the present invention, a microfluidic channel 100 using a single sound pressure is applied instead of a conventional syringe pump using a positive pressure as an apparatus for producing a cosmetic composition. That is, according to the present invention, since a single sound pressure is applied to the microfluidic channel 100 as a discharge method of the emulsified material, the apparatus according to the present invention can be directly applied to a general cosmetic container and a pump structure.

Conventionally, it has been difficult to form and maintain emulsified particles without using an excess amount of surfactant (1% to 5%) because the interfacial tension between the external fluid and the internal fluid is high and they are not easily mixed with each other. However, according to the present embodiment, since the influence of the surface force on the fluid is much greater than the body force in the microfluidic channel 100 having the very small characteristic length (less than the millimeter), the surfactant, It is advantageous that the emulsifying action can be performed quickly by not using or adding a minimum amount. Also, the principle that any one of two fluids that do not easily mix with each other breaks off the flow of another fluid to form emulsified particles, also helps to reduce the surfactant.

Although the emulsification method using the microfluidic channel 100 has many advantages as described above, it is difficult to apply it to a cosmetic manufacturing apparatus because the production speed is limited as compared with existing emulsification apparatuses using a large tank and a stirrer. In order to solve such a problem of production rate, the present invention has developed a microfluidic channel 50 applicable to a container, and adopted a momentary emulsification method capable of emulsification based on the amount of discharge once at a desired time of the user.

The outer fluid infusion tube 30 and the inner fluid infusion tube 40 are connected to the first channel 50 of the fluid channel 100 at one side thereof. The fluid channel 100 may be formed on the bottom surface of the housing 10, for example, in the form of a flow passage for moving the fluid. In addition, the fluid channel 100 may include a first channel 50 forming the lower portion and a second channel 80 stacked on the upper portion of the first channel 50. However, according to the embodiment, the first channel 50 may be stacked on top of the second channel 80, or may be arranged in a non-stacked structure. In the case where the first channel 50 and the second channel 80 are formed in a laminated structure as in the present embodiment, space utilization in the housing 10 can be increased and the overall size of the product can be reduced.

First, the first channel 50 may be provided with injection ports communicating with the outer fluid injection tube 30 and the inner fluid injection tube 40. That is, the first channel 50 is an inlet passage for the inner fluid moved along the inner fluid injection tube 40 and the outer fluid injection port 51, which is an inlet path for the outer fluid flowing along the outer fluid injection tube 30, And an inner fluid injection port 54.

The outer fluid flowing into the first channel 50 through the outer fluid injection port 51 may be divided into a first branch tube 52 and a second branch tube 53 and may be moved to the downstream side toward the pump 70 . Refers to a direction in which the fluid stored in the fluid receiving portion 20 is discharged to the outside through the first channel 50 and the tube 60 through the pump 70 by the pump operation of the user it means.

Similarly, the inner fluid that has flowed into the first channel 50 through the inner fluid injection port 54 may be moved to the downstream side along the inner fluid moving tube 55. The external fluid moved along the first branch tube (52) and the second branch tube (53) and the internal fluid moved along the internal fluid moving tube (55) meet each other at the joint portion (56). That is, the joint portion 56 means the point where the foreign body and the internal fluid first meet in the housing 10.

The extracorporeal fluid and the inner fluid reached at the joint portion 56 pass through the emulsification portion 58 and become an emulsion, that is, an emulsified material. In the present embodiment, an orifice 58 having a relatively narrower width than that of the joint portion 56 is provided as the emulsification portion 58. [ The outer surface fluid and the inner fluid that are encountered at the joint portion 56 pass through the orifice 58 and flow in the direction of the resultant fluid in the flow direction (horizontal direction) of the fluid (the direction perpendicular to the inner side of the orifice 58) 58), the shear force acts on the inner fluid in the diagonal direction to cut off the flow of the inner fluid, thereby forming an emulsified material. Specifically, the two fluids that do not mix with each other increase the capillary instability when passing through the orifice 58 in an unstable interface state, and the channel with the orifice 58 has less energy than the channel without the fluid, The flow can be broken, and the interrupted fluid thus formed is formed into a spherical shape in order to maintain a stable state.

The emulsification portion 58 is formed by interrupting the flow of the mixed fluid and dispersing the mixed fluid in the particle-like state in the particle state. In the present embodiment, the orifice is provided as the emulsification portion 58 , But the spirit of the present invention is not limited thereto. Specifically, the emulsification method using the same orifice as in the present embodiment can be referred to as a flow-focusing method emulsification. This allows the fluid of different phases to flow in the same direction, but the orifice is positioned at the merging portion, (Flow-focusing method). When the orifice is used, the flow of the extraneous fluid changes diagonally inside the orifice, and a stronger shear force can be transmitted to the mixed fluid, so that the emulsion particle can be formed more easily and emulsion particles of a certain size can be formed .

In addition, various embodiments may be applied to the emulsification portion 58. For example, a method of emulsifying the fluids of different phases in the same direction while moving them in the same direction (Co-Flow method) (Cross-flow method), a method of forming emulsion particles in the joint portion by adjusting the aspect ratio of the entry port of the extracorporeal fluid into the entrainer and the entrances of the entrainer fluid to the joint portion (step emulsification method) Or a method of forming an emulsion particle by passing a mixed fluid of two phases through a hole of a membrane (Membrane Emulsification method) may be used.

The emulsification unit 58 may use a power source such as an electric control, a magnetic control, a centrifugal control, an optical control, a vibration control, a piezoelectric material A channel in which emulsified particles are formed using a piezoelectric control or the like may be used.

In addition, the emulsification portion 58 may form emulsion particles by changing the viscosity of the fluid, the interfacial tension, and the wettability. For example, the emulsion 58 may be formed of Electrorheological (ER) or Magnetorheological (MR) fluids, Fluids may be applied.

The emulsified material passing through the orifice 58 moves along the emulsified material moving pipe 57. Refers to the direction opposite to the direction of movement of the fluid by the pump operation of the user as the opposite direction of the "downstream ", that is, the direction in which the pump 70, the tube 60, the fluid channel 100, Means a direction toward the accommodating portion 20.

Conventionally, in order to control the size of the emulsified material, a method of controlling the amount of the surfactant added to the emulsified material was used. However, according to the present invention, the size of the emulsified material can be adjusted by adjusting the width of the orifice 58 only. However, the width of the orifice 58 has a minimum designed value, and thus there is a minimum limit of the size of the emulsified material.

In particular, in the case of cosmetics manufactured using an emulsification apparatus, the size and content of emulsified particles are important factors for determining the quality of cosmetics. In order for emulsified particles to form, the injection ratio of the extracorporeal fluid to the inner fluid should generally be the same or higher. For example, the injection volume of the extracorporeal fluid may be 1 to 30 times the injection volume of the inner fluid.

In the case of a microfluidic channel 100 using a single sound pressure as in the present invention, the flow rate of the fluid is determined by the structural elements of the fluid channel 100 and the flow conditions of the fluid, . Structural elements of the fluid channel 100 include, for example, the height of the channel, the width of the orifice, and the width ratio of the injection channels of the respective fluids. The flow conditions of the fluid are, for example, the intensity of the sound pressure, the flow ratio of the two fluids, and the viscosity ratio of the two fluids.

The emulsified particles have a higher viscosity as the channel height is lower, the width of the orifice is narrower, the sound pressure is higher, the flow rate of the fluid to the inner fluid is larger and the viscosity of the inner fluid is higher than that of the fluid And on the contrary, the size of the emulsified particles becomes large.

In the present invention, as a method of controlling the flow rate ratio between the inner fluid and the outer fluid, a method of controlling the inner diameter of each inlet of the inner fluid and the outer fluid is used. Specifically, when the inner diameter of the outer fluid injection port is made two times wider than the inner diameter of the inner fluid injection port, the flow rate of the outer fluid under the single sound pressure is increased by two times as compared with the inner fluid. In this way, the flow rate ratio between the inner fluid and the outer fluid can be adjusted.

In addition, two effects can be expected by adjusting the flow rate of injecting three kinds of fluids in the above-described method when manufacturing multiple formulations. First, when the primary emulsion is emulsified, the film thickness of the multiple formulations manufactured after the secondary emulsification can be adjusted by controlling the flow ratio of the external fluid to the flow rate of the same internal fluid. Second, by adjusting the injection flow ratio of the intimal fluid and the extracellular fluid during the second emulsification, the number of encapsulation of the first emulsified emulsion particles injected intrinsically into the second channel in the multiple formulation can be controlled.

The emulsified material passing through the joint portion 56 and the orifice 58 moves along the emulsified material moving tube 57. At this time, a first emulsification material passage 59 is formed at an end of the emulsification material movement pipe 57 to communicate with the second channel 80 to serve as a passage through which the emulsification material escapes from the first channel 50. The second channel 80 is formed with a second emulsified material passage 84 that communicates with the first emulsified material passage 59 and serves as a passage for receiving the emulsified material into the second channel 80.

The configuration of the second channel 80 communicating with the first channel 50 is as follows.

4 is a plan view showing the configuration of a second channel stacked on top of the first channel of the fluid channels of the device. 5A and 5B are cross-sectional views of an emulsified material showing a state in which W / O / W emulsion particles or O / W / O emulsion particles are formed through the second channel.

Referring to the drawings, the first channel 50 and the second channel 80 may have the same structure. That is, the first channel 50 and the second channel 80 are different from each other only in the direction in which the first channel 50 and the second channel 80 are disposed. For example, the second channel 80 may be stacked on the first channel 50 with the first channel 50 rotated 180 degrees. The second emulsion material passage 84 of the second channel 80 communicating with the first emulsion material passage 59 of the first channel 50 is connected to the inner fluid injection port 54 of the first channel 50 It may be a corresponding part. That is, the emulsified material flowing into the second channel 80 through the second emulsified material passage 84 forms the inner shape of the multiple formulations.

As shown in the drawing, the emulsified material flowing into the second channel 80 through the second emulsified material passage 84 is moved along the emulsified material pipe 85 to the multiple formulation leg portion 86.

The second channel (80) is formed with a movement path of the outermost surface fluid delivered from the outermost surface fluid injection pipe (46). Specifically, the outermost fluid stored in the outermost container 45 in the housing 10 moves to the outermost fluid injection port 81 of the second channel 80 along the outermost fluid injection pipe 46 by the negative pressure do. The outermost fluid injection port 81 of the second channel 80 corresponds to the outer fluid injection port 51 of the first channel 50. The outermost fluid introduced into the second channel (80) through the outermost fluid injection port (81) is moved to the multiple formulation leg part (86) through the branch tubes (82, 83).

The multiple formulation leg portion 86 is a portion corresponding to the joint portion 56 of the first channel 50 and is a portion where the emulsified material and the outermost fluid meet.

The emulsified material and the outermost fluid encountered in the multiple formulation leg portion 86 pass through the emulsification portion 87a and are emulsified. In this embodiment, the orifice 87a having a relatively narrower width than that of the multiple formulation leg portion 86 is provided as the emulsification action portion 87a. The outermost fluid and the emulsified material encountered in the multiple formulation leg portion 86 pass through the orifice 87a having a relatively narrow width so that the outermost fluid contacts the direction (vertical direction) inside the orifice 87a Directional orifice 87a in the direction of flow (horizontal direction) of the resultant directional orifice 87a), so that the flow of the emulsified material is interrupted to form a multiple formulation. Specifically, when two fluids that are not mixed with each other pass through the orifice 87a in an unstable state, the capillary instability is increased, and the channel having the orifice 87a has less energy than the channel having no channel. The flow can be broken and the emulsified material thus formed is formed into a spherical shape in order to maintain a stable state. The material thus formed is referred to as multiple emulsions, i.e., multiple formulations.

The multiple formulations formed through the orifices 87a are caused to move along the multiple formulating moving pipes 87. The multiple formulations that have passed through the multiple dispensing tube 87 are moved to the multiple dispensing outlet 88 formed at the end of the multiple dispensing tube 87. The multiple formulation outlet 88 is in communication with the tube 60 and serves as a passageway through which the multiple formulations escape from the second channel 80.

On the other hand, the tube 60 can be made of a transparent material so that the user can identify the emulsified material moving through the tube 60 from the outside. At this time, only the portion of the housing 10 surrounding the tube 60 should be made of a material that can be visually confirmed from the outside, so that the emulsified material moving through the tube 60 can be confirmed from the outside.

A pump 70 is installed at the end of the tube 60 and the user can take out the emulsified material that has passed through the cosmetic composition manufacturing apparatus 1 through the discharge port of the pump 70.

Although the second channel 80 is stacked on the first channel 50 as described above, the present invention is not limited thereto. For example, the second channel 80 may be laminated to the lower side of the first channel 50. In this case, since the first channel 50 is disposed closer to the vessels 21 and 22, the outer fluid and the inner fluid are first supplied to the first channel 50 and emulsified. Then, (80), can be further simplified. In addition, the first channel 50 and the second channel 80 may be formed on the same plane. In this case, the first emulsified material passage 59 of the first channel 50 and the second emulsified material passage 84 of the second channel 80 may be substantially the same. For example, the first channel 50 may be disposed in the inner space of the outermost fluid movement branch pipe 82, 83.

In this embodiment, the second channel 80 has substantially the same structure as the first channel 50, but the concept of the present invention is not limited thereto. The second channel 80 may be a microfluidic channel using various methods for dispersing one of the fluids in a particle state in the other oil when the two fluids having different phases as the microfluidic channel meet, as described above. For example, the first channel 50 uses an orifice as an emulsification portion, and the second channel 80 uses an emulsification portion that allows the first emulsion to be supplied to the outermost fluid flowing in one direction at a predetermined angle It can be used.

The multiple formulations that can be produced by the above-described constitution can be broadly classified into two cases: the case where the outermost fluid is oily phase (O) and the case where it is water phase (W).

When the outermost fluid is oily phase O, the inward fluid is one of oil phase O, water phase W and gas phase G, and the outer phase fluid is one of oil phase O and water phase G . O / O, W / O / O, W / W / O, G / O / O and G / W / O when the outermost fluid is O Can be prepared. In addition, even when the outermost fluid is water phase W, the in-phase fluid is one of oil phase O, water phase W and gas phase G, and the external phase fluid is one of oil phase O and water phase G Lt; / RTI > O / W, O / W / W, W / O / W, W / W / W, G / O / W and G / W / W when the outermost fluid is water (W) Can be prepared. Here, it can be understood that when both the inner fluid and the outer fluid, or both the outer fluid and the outermost fluid are oil phase (O) or water phase (W), fluids of similar hydrophilic nature but not intermixing with each other are used have.

On the other hand, the inner wall of the multiple formulating moving pipe 87 of the second channel 80 may be provided so as to have properties corresponding to the hydrophilicity of the outermost fluid. In this case, the outermost phase fluid constituting the external phase of the multiple formulations is pulled toward the inner wall side of the multiple formulating moving pipe 87, and the first emulsifying material is relatively moved away from the inner wall side of the multiple formulating moving pipe 87, The state in which the fluid forms the outer shape of the multiple formulations can be stably maintained and moved. For example, when the outermost fluid is oil, the inner wall of the multiple formulation moving pipe 87 may be coated with a hydrophobic material or a hydrophobic film, and in the case where the outermost fluid is water, it may be coated with a hydrophilic material or a hydrophilic film. Depending on the embodiment, other configurations of the second channel 80 as well as the multiple formulation moving pipe 87 may be formed to have characteristics corresponding to the hydrophilic capacity of the outermost fluid. That is, at least a part of the second channel 80 may be formed to have a hydrophilic capacity corresponding to the hydrophilic capacity of the outermost fluid.

In addition, the inner wall of the emulsifying material moving pipe 57 of the first channel 50 may be provided so as to have properties corresponding to hydrophilicity of the outer-surface fluid. In this case, the contaminant fluid forming the contaminant of the emulsified material is pulled toward the inner wall of the emulsifying material moving pipe 57, and relatively the inner fluid moves away from the inner wall of the emulsifying material moving pipe 57, And can be moved. For example, when the external fluid is oil, the inner wall of the emulsifying material moving pipe 57 may be coated with a hydrophobic material or a hydrophobic film, and in the case where the external fluid is water, the inner wall may be coated with a hydrophilic material or a hydrophilic film. Depending on the embodiment, not only the emulsifying material moving pipe 57 but also other structures of the first channel 50 may be formed to have properties corresponding to the affinity of the foreign body fluid. That is, at least a part of the first channel 50 may be formed to have a hydrophilic capacity corresponding to the affinity of the foreign body fluid.

Here, as the hydrophilic substance or the hydrophilic film, a material having a contact angle with water of 0 to 50 degrees may be used, and as the hydrophobic substance or the hydrophobic film, a material having a contact angle with water of 70 to 120 degrees may be used.

Hereinafter, the flow of the fluid will be described as an example of forming the O / W / O emulsion particles as an example of the multiple formulations and forming the W / O / W emulsion particles.

First, the process of extracting O / W / O emulsified particles will be described as follows.

In order to extract the O / W / O emulsion particles, the extracellular fluid may be a hydrophilic fluid such as water and the inner fluid may be a hydrophobic fluid such as an oil. Then, the hydrophilic fluid is stored in the outer container (21) and the hydrophobic fluid is stored in the inner container (22).

In this state, when the user presses and releases the pump 70, a negative pressure is applied to the fluid receiving space and the fluid movement path, and the hydrophilic fluid and the hydrophobic fluid are drawn out of the respective containers.

Specifically, the hydrophilic fluid is moved along the trauma fluid injection tube 30 to the trauma fluid injection port 51 of the first channel 50, and the hydrophobic fluid flows along the intracardiac fluid injection tube 40 to the first channel 50 To the inner fluid injection port 54 of the internal combustion engine. The hydrophilic fluid and the hydrophobic fluid transferred to the first channel (50) meet each other at the joint portion (56) of the first channel (50) and pass through the orifice (58). At this time, the hydrophobic fluid is dispersed into small particles in the hydrophilic fluid. That is, an emulsified material in which a hydrophilic fluid surrounds a hydrophobic fluid is formed.

According to this process, oil-in-water (O / W) emulsion particles in which water is dispersed in the oil are produced (see FIG.

At this time, the first channel 50, particularly, the emulsifying material moving pipe 57 may be made of a hydrophilic material or the inner wall through which the fluid flows may be coated with a hydrophilic material. Specifically, when the emulsified material moving tube 57 is made of a hydrophilic material, the hydrophilic fluid portion is moved to the emulsified material moving tube (not shown) 57). Therefore, the O / W emulsified particles as described above can be smoothly moved along the emulsified matter moving tube 57 while maintaining the shape and structure thereof.

The O / W emulsified particles having passed through the first emulsified material passage 59 of the first channel 50 are moved to the second channel 80 stacked on the first channel 50. Specifically, the O / W emulsified particles are dispersed in the second channel 80 along the second emulsified material passage 81 of the second channel 80 communicated with the first emulsified material passage 59 of the first channel 50, .

The second emulsified material passage 84 is a portion corresponding to the inner fluid inlet port 54 of the first channel 50 and the O / W emulsified particles moved through the second emulsified material passage 84 are in contact with the inner surface of the multi- . That is, the O / W emulsified particles introduced into the second channel 80 through the second emulsified material passage 81 are moved to the multiple formulation leg portion 86 along the emulsified material pipe 86.

The outermost fluid is then transferred from the outermost container 45 through the outermost fluid injection tube 46 to the outermost fluid injection port 81 formed in the second channel 80. That is, the outermost fluid forms a multiple-phase trauma. Generally, the outermost fluid may be a hydrophobic fluid having a similar range or substantially the same hydrophilicity as the inner fluid. That is, in order for the manufactured multiple formulations to have both the effects of the W / O emulsion particles and the effect of the O / W emulsion particles, the outermost fluid may be a hydrophobic fluid so that the hydrophobic fluid can cover the outer surface of the O / have.

The outermost fluid introduced into the second channel 80 is moved to the multiple formulation leg portion 86 along the outermost fluid movement branch tubes 82 and 83 of the second channel 80. Therefore, the O / W emulsified particles and the outermost fluid are brought into contact with each other in the orifice 87a through the emulsified material and the outermost fluid passing through the multiple formulation leg portion 86 to produce O / W / O emulsified particles Reference).

The O / W / O emulsified particles produced according to the above process are moved to the multiple formulation outlet 88 through the multiple formulation transfer tube 87.

At this time, the second channel 80, in particular, the multiple formulating moving pipe 87 may be made of a hydrophobic material or the inner wall may be coated with a hydrophobic material. Specifically, when the multiple formulation moving pipe 87 is made of a hydrophobic material, the hydrophobic fluid portion of the emulsion material is attracted to the inner wall of the emulsion material moving pipe 57 because the multiple formulation is made of the hydrophobic fluid outside. Therefore, the O / W / O emulsified particles as described above can be smoothly moved along the multiple formulation moving pipes 87 while maintaining their shape and structure.

The O / W / O emulsion particles moved along the multiple formulation outlet 88 can be taken out to the user through the injection port of the pump 70 through the tube 60.

Similarly, the process of extracting the W / O / W emulsified particles will be described with reference to the drawings.

In order to extract the W / O / W emulsified particles, the extracellular fluid may be a hydrophobic fluid such as oil and the intrinsic fluid may be a hydrophilic fluid such as water. Then, the hydrophobic fluid is stored in the outer container 21 and the hydrophilic fluid is stored in the inner container 22.

In this state, when the user presses the pump 70, the pressure of the fluid receiving space and the fluid moving path in the housing 10 becomes high. Then, when the user releases the pressure of the pump 70, negative pressure is applied to the fluid receiving space and the fluid moving path, and the hydrophobic fluid and the hydrophilic fluid are drawn out of the respective containers.

Specifically, the hydrophobic fluid moves along the traumatic fluid injection tube 30 to the traumatic fluid injection port 51 of the first channel 50, and the hydrophilic fluid flows along the intimal fluid injection tube 40 to the first channel 50 To the inner fluid injection port 54 of the internal combustion engine. The hydrophobic fluid moved to the first channel 50 moves to the joint portion 56 along the first branch tube 52 and the second branch tube 53 and the hydrophilic fluid moves along the inner fluid moving tube 55 And moves to the joint portion 56. That is, the hydrophobic fluid and the hydrophilic fluid meet each other at the joint portion 56 of the first channel 50 and pass through the orifice 58. At this time, the hydrophilic fluid is dispersed into small particles in the hydrophobic fluid (emulsification phenomenon). That is, an emulsified material in which the hydrophobic fluid surrounds the hydrophilic fluid is formed.

The emulsified material passing through the orifice 58 moves along the emulsified material moving pipe 57. This process forms water-in-oil (W / O) emulsified particles in which oil is dispersed in water (see FIG. 3B).

At this time, the first channel 50, particularly, the emulsifying material moving pipe 57 may be made of a hydrophobic material or the inner wall may be coated with a hydrophobic material. Specifically, when the emulsifying material moving tube 57 is made of a hydrophobic material, the hydrophobic fluid portion of the emulsifying material is moved to the emulsifying material moving tube 57). Therefore, the W / O emulsified particles as described above can be smoothly moved along the emulsion moving tube 57 while maintaining the shape and structure thereof.

The W / O emulsified particles having passed through the first emulsified material passage 59 of the first channel 50 are moved to the second channel 80 stacked on the first channel 50. Specifically, the W / O emulsified particles are dispersed in the second channel 80 along the second emulsified material channel 84 of the second channel 80, which communicates with the first emulsified material channel 59 of the first channel 50, .

The second emulsified material passage 84 is a portion corresponding to the inner fluid inlet port 54 of the first channel 50 and the W / O emulsified particles moved through the second emulsified material passage 84 are in contact with the inner surface of the multi- . That is, the W / O emulsified particles introduced into the second channel 80 through the second emulsified material passage 81 are moved to the multiple formulation leg portion 86 along the emulsion material pipe 86.

The outermost fluid is then transferred from the outermost container 45 through the outermost fluid injection tube 46 to the outermost fluid injection port 81 formed in the second channel 80. That is, the outermost fluid forms a multiple-phase trauma. Generally, the outermost fluid may be a hydrophilic fluid having a similar range or substantially the same hydrophilicity as the inner fluid. That is, in order for the manufactured multiple formulations to have both the moisturizing effect of the W / O emulsified particles and the fresh feel of the O / W emulsified particles, the outermost fluid is a hydrophilic fluid Lt; / RTI >

The outermost fluid introduced into the second channel 80 is moved to the multiple formulation leg portion 86 along the outermost fluid movement branch tubes 82 and 83 of the second channel 80. Therefore, the W / O emulsified particles and the outermost fluid come into contact with each other in the orifice 57a and the W / O / W emulsified particles are passed through the multiple formulation leg portion 86 to produce the W / O / W emulsified particles Reference).

The W / O / W emulsified particles produced according to the above process are moved to the multiple formulation outlet 88 through the multiple formulation transfer tube 87.

At this time, the second channel 80, in particular, the multiple formulating moving pipe 87, may be made of a hydrophilic material, or the inner wall may be coated with a hydrophilic material. Specifically, when the multiple formulation moving pipe 87 is made of a hydrophilic material, the hydrophilic fluid portion of the emulsified material is attracted to the inner wall of the emulsion material moving pipe 57 because the multiple formulations are made of the hydrophilic fluid. Therefore, the above-mentioned W / O / W emulsified particles can be smoothly moved along the multiple formulation moving pipe 87 while maintaining the shape and structure thereof.

The W / O / W emulsified particles moved along the multiple formulation outlet 88 can be taken out to the user through the injection port of the pump 70 through the tube 60.

An example of the W / O / W emulsified particles produced according to the above process is shown in FIG. Specifically, FIG. 6 shows an experimental example of W / O / W emulsified particles.

As described above, according to the present invention, since the multiple formulations are manufactured by the operation of the user's pump and the external dispensing of the produced multiple formulations is performed, there is an advantage that the multiple formulations can be manufactured and supplied at a time when the user needs them .

In addition, according to the present invention, it is possible to manufacture and supply a plurality of formulations in such a manner as to emulsify instantaneously at a point in time required by a user, so that the manufacturing process is very simple and the manufactured formulations can also maintain a stable state.
