Cosmetic ball and its manufacturing method {Cosmetic Ball and Manufacturing Method thereof}

The present invention relates to a cosmetic ball and a method for manufacturing the same, and more particularly, to a cosmetic ball manufactured using a biodegradable outer skin and a method for manufacturing the same.

Existing soft capsule cosmetics are made of gelatin, vegetable carrageenan, agar, etc., so they do not use plastic, but use natural products and are good for molding and processing at low temperatures. However, soft capsule cosmetics have the characteristic of being vulnerable to moisture due to the nature of the material. When cosmetics containing moisture are made into soft capsules, they react with moisture and dissolve. In addition, the soft capsules are hardened over time due to evaporation of moisture in the soft capsules in the atmosphere.

Except for color cosmetics such as skins, lotions, and creams, most of the basic cosmetics have a moisture content of 50% or more, so these types of cosmetics cannot be placed in a soft capsule, and most of them must contain at least 90% oil. .

For this reason, it is impossible to make various types of cosmetics because soft capsule cosmetics have many restrictions according to moisture content. In addition, since soft capsules are sensitive to moisture and temperature in the atmosphere, they should be stored in a container that can be sealed separately.

The container of cosmetics has a function of safely storing cosmetics from internal and external environments. The container should not be dissolved by the cosmetics or the cosmetics should not penetrate into the container, and the container should not be deformed by the contents over time or the components of the container should not be dissolved and mixed with the contents.

However, since most basic cosmetics contain much more moisture than oil, the cosmetic container must prevent moisture from escaping out of the container, and the container must not be dissolved by moisture or oil. In addition, the container itself should not be deformed by external moisture or temperature during the cosmetic shelf life.

Soft capsules, which are used a lot in the past, are made of gelatin or carrageenan, so they have a property of being dissolved by water. Therefore, there is a limit in that only oil substances are acceptable. Therefore, it is not suitable for use as a container for general cosmetics.

In addition, when cosmetics are used in the form of opening and closing the lid of the container, cosmetic ingredients such as vitamins are combined with oxygen in the atmosphere to be oxidized and destroyed, and the state of storage of cosmetic contents in the air, although invisible to the naked eye There is a risk of contamination in the process of opening and closing cosmetics because there are fungi or bacteria that affect the product.

Therefore, in order to solve this problem, the capsule is made into a disposable sealed spherical structure using biodegradable plastic and stored for more than a year even if the cosmetic containing a lot of moisture is stored for more than a year, and the capsule is not deformed or eluted by the contents, so the contents are safely preserved. A cosmetic container is needed that prevents contamination of harmful substances in the air and prevents oxidation at the same time by putting an amount suitable for one-time use by adults in a spherical ball-shaped capsule and keeping it sealed until used. .

In addition, there is a need for a cosmetic container that is decomposed by microorganisms after a certain period of time even if it is buried and helps to prevent environmental pollution.

The present invention is derived from this technical background, and by making a cosmetic ball into a disposable sealed spherical ball using a blow molding injection method with a material containing biodegradable plastic, filling and sealing the cosmetic, in the existing soft capsule cosmetics Prevents dissolution of capsules in unresolved moisture, and allows cosmetics containing a lot of moisture to be safely stored for more than one year, and cosmetic contamination factors (fungus, contents, hands and It is an object to provide a cosmetic ball and a manufacturing method thereof that can reduce the content of preservatives for preserving the contents from these contaminants during the manufacturing of cosmetics by fundamentally blocking the contact of

In addition, the present invention is made of a material that is biodegradable by microorganisms after a certain period of time after the cosmetic ball material is buried to provide a cosmetic ball capable of reducing the prevention of environmental pollution caused by existing plastic cosmetic containers and a method for manufacturing the same There is this.

The present invention for achieving the above object includes the following configuration.

That is, the cosmetic ball according to an embodiment of the present invention forms a hollow sealed space in a blow molding method, and includes an outer skin made of a biodegradable material and a filler to be filled in the closed space formed by the outer skin. .

According to one aspect, the cosmetic ball further includes a UV adhesive layer for sealing the injection hole formed in a part of the outer skin for filling the filler and the injection hole formed in a part of the outer skin.

In addition, it characterized in that it further comprises a plasma surface treatment layer between the outer skin and the UV adhesive layer.

On the other hand, the manufacturing method of the cosmetic ball comprises the steps of forming a hollow sealed space in a blow molding method using an outer skin, which is a biodegradable material, and forming an injection hole in a part of the outer skin to apply a filling to the formed closed space. It characterized in that it comprises the step of filling and sealing the formed injection hole.

Among cosmetic ingredients, active ingredients such as vitamins combine with oxygen in the atmosphere to oxidize and discolor, and the performance of active ingredients deteriorates, and although it is invisible, it affects the storage condition of cosmetic contents in the air. The presence of harmful fungi or bacteria may cause contamination in the process of opening and closing cosmetics. For this reason, cosmetics contain a large amount of preservatives to prevent such contamination.

However, according to the present invention, the content of preservatives can be reduced when manufacturing cosmetics, and the active ingredient is not in the form of opening and closing the lid of a cosmetic container and using it several times, but squeezing a hole in the outer skin when using it and using it all at once. It is possible to reduce oxidation combined with this oxygen, and to provide a cosmetic ball capable of storing active ingredients of cosmetics for a long period of time without deterioration and a method for manufacturing the same.

In addition, the present invention has the effect of providing a cosmetic ball capable of preventing environmental pollution caused by cosmetic containers made of existing plastics, which are biodegraded by microorganisms after a certain period of time after landfilling, and a manufacturing method thereof.

In addition, according to the present invention, even if the contents containing a lot of moisture are contained, the effect that the outer skin does not collapse due to moisture is derived. In the case of existing soft capsule cosmetics, the material is gelatin, vegetable carrageenan, agar, etc., so it is good for molding and processing at low temperatures, but it is weak against moisture. Most cosmetic products contain more than 50% of water, so these contents cannot be contained in capsules, and most of them must contain at least 90% of oil. It is not dissolved by the contents and at the same time has all the functions of a cosmetic container in everyday environment.

Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the configuration of a cosmetic ball according to an embodiment of the present invention.

The cosmetic ball 10 according to an embodiment is made of, for example, NuPlastiQ, a starch biopolymer made of a plasticized starch resin having a low water content by BioLogiQ in the form of pellets.

A product (BioBlend) made by mixing 25% of this pellet and 75% of LDPE for extrusion is provided, and 3% of the LDPE-based color masterbatch required for the color of the nose ball is mixed with it using blow molding direct blow The outer skin 100 can be produced.

And since the outer skin 100 produced in this way is biodegraded after a certain period of time when buried and does not generate microplastics, it can be helpful in preventing environmental pollution of existing plastics.

As in FIG. 1 , the cosmetic ball 10 according to an embodiment includes an outer skin 100 , a filler 110 , an injection hole 105 , a UV adhesive layer 130 , and a plasma surface treatment layer 120 . .

The outer skin 100 forms a hollow sealed space in a blow molding method, and is composed of a biodegradable material.

Blow molding is a method in which a parison or sheet of thermoplastic plastic is softened by heating in a split mold to inflate using air pressure, etc., and then cooled when it is brought into close contact with the mold to obtain a hollow body.

Ordinarily, by extruding a heat-melted thermoplastic plastic molding material, or by inserting a parison preformed into a tube shape according to the injection method or a two-piece sheet into a mold for blow molding, heat softening is performed, and then air is blown into the hollow product. to mold

There are various types of blow molding depending on the state molding method of the parison, and representative ones include injection blow molding, extrusion blow molding, sheet blow method (sheet parison method), direct blow molding, injection erosion blow molding, and the like.

According to an embodiment, the outer skin 100 may be made in a completely sealed form of a biodegradable material by manufacturing a special mold capable of molding it and using a direct blow molding machine.

The outer skin 100 can be implemented in the form of any cosmetic container that can be used once. And it can be implemented with all plastics and materials including rubber that can contain cosmetics.

In addition, the cosmetic contents and the outer skin 100 must be chemically stable to contain the cosmetics as the filler 110 , and to have elasticity enough to squeeze the filler 110 and elute it during use.

That is, the outer skin 100 does not elute through the outer skin even when the cosmetic filler 110 is stored for a long time and may be made of a material that is biodegradable in nature among environmental factors or a material of vegetable plastic that can reduce Co2. .

In one embodiment, when the container formed of the outer skin 100 is punctured with a pin to use the filler 110, the thickness of the outer skin 100 is adjusted to give elasticity so that the contents can be easily eluted. It is possible to be implemented to satisfy the above conditions.

In the manufacture of the outer skin 100, a special mold capable of forming the outer skin 100 is manufactured to make a hollow sealed outer skin, and is made in a completely sealed form with a direct blow molding machine.

In one embodiment, the outer skin 100 provides a function to safely store the filling 110 from the outside. The outer skin 100 is preferably implemented with a type of material that does not dissolve by the filler 110 or the filler 110 penetrates into the outer skin 100 .

In addition, in general, cosmetics, which are fillers 110 , have high moisture and oil content, preventing moisture from escaping out of the outer skin 100 , and should be implemented with a material in which the outer skin 100 is not dissolved by moisture or oil. .

In one embodiment, the outer skin 100 may be implemented with potato starch-based low-crystalline bioplastic (NuPlastiQ). That is, the outer skin 100 creates a sealed biodegradable plastic hollow container.

In one embodiment, the outer skin 100 using a direct blow method to manufacture a hollow sealed type container.

At this time, the container shape formed by the outer skin 100 includes all hollow container shapes that can contain cosmetic contents. For example, it is possible to transform into various shapes such as a sphere, a star, and a heart shape.

In one embodiment, the thickness of the outer skin 100 may be 0.2mm to 0.4mm. However, the present invention is not limited thereto and may be adjusted depending on the shape.

The sealed space formed by the outer skin 100, that is, the size of the container, can be manufactured to a size according to the amount of cosmetic content used as the filling 110 at one time. As an example, the contents may be manufactured in a size that can contain up to 0.5cc to 3cc.

The cosmetic ball 10 according to an embodiment in which the outer skin 100 is formed in the form of a container capable of containing the filler 110 can maintain its shape even when the filler 110 having a high water content is filled.

The filling material 110 is filled in the closed space formed by the outer skin 100 . In one embodiment, the filler 110 includes all contents of the cosmetic type.

The filling material 110 is injected into the space formed by the outer skin 100 through the nozzle tube of the filling device in the form of a needle.

2 is an exemplary view showing a cosmetic ball in a state in which the filling mechanism is inserted.

As shown in FIG. 2 , the filling mechanism 20 fills the filling material 110 into the space formed in the outer skin 100 through the injection hole 105 of the cosmetic ball 10 .

In one embodiment the injection hole 105 is created by the insertion of the filling device 20 . That is, the filling mechanism 20 is implemented to fill the contents by directly punching a nozzle tube in the form of an injection needle into the container.

3 is an exemplary diagram illustrating the configuration of a filling mechanism according to an embodiment of the present invention.

In one embodiment, the filling mechanism 20 includes the discharge unit 210 for discharging the filling material 110 and the air discharged by the filling of the filling material 110 from the enclosed space created by the outer skin 100 ( a) includes an air discharge unit 220 for discharging.

When injecting the contents through the nozzle into a closed space, the filling speed may be slow due to the closed structure. This phenomenon can be achieved by changing the structure of the nozzle, that is, the filling mechanism, so that as much air as the filling amount is discharged through the nozzle at the same time, the speed and accuracy of filling the contents in an enclosed space can be increased.

According to an embodiment, in a method that can fill a completely enclosed space with plastic, the outer skin 100 is filled with a plastic material through a nozzle such as a syringe needle, that is, the filling mechanism 20 from the outside of the outer skin 100 . A hole is forcibly made and injected inside.

In this case, it takes a long time for the air to come out through the gap because the amount of air in the plastic space must be discharged around the syringe needle inserted into the outer skin as much as the amount of cosmetic injection. Sometimes the contents come out.

In order to eliminate this phenomenon, it is necessary to devise a method in which the amount of air is discharged at the same time as filling.

According to one aspect of the present invention for solving such a problem, the filling mechanism 20 is a filling from the closed space created by the discharge part 210 for discharging the filling, and the outer skin 100, as shown in FIG. It includes an air discharge unit 220 for discharging air discharged by filling.

In addition, one end surface of the filling mechanism 20 is characterized in that it is inclined to form the injection hole 105 by applying pressure to a part of the outer skin 100 .

In general, when the cosmetic contents are injected into a closed space, the filling time of the contents is delayed due to the internal pressure, and it is difficult to fill the correct amount. Therefore, according to one embodiment, filling is performed using a special type of nozzle separately equipped with an air discharge unit 220 capable of removing pressure to the outside in the nozzle unit of the filling mechanism 20 to quickly and accurately fill in the correct amount. can be filled.

The filling mechanism 20 is coupled with a three-axis robot and a dispensing system. The dispensing valve may be composed of a volume valve capable of discharging a certain amount and a special needle-shaped nozzle capable of penetrating the outer skin 100 into the valve discharging part, that is, the filling mechanism 20 shown in FIG. 3 .

The three-axis robot fills cosmetic fillings 110 in cosmetic balls 10 positioned at regular intervals by a program. In this case, the filling amount may be, for example, 0.5ml to 1ml. However, the present invention is not limited thereto.

In addition, in order to continuously fill the filling material 110 , a separate compression tank may be connected to the dispensing nozzle to continuously perform filling in an accurate amount.

When the filling 110 such as cosmetics is injected into the enclosed space, the filling time of the contents is delayed due to the internal pressure, and it is difficult to fill the correct amount.

Therefore, according to an embodiment, the filling mechanism 20 further includes an air discharge unit 220 for discharging air discharged by filling of the filling material 110 from the enclosed space to be separated from the discharge unit.

The UV adhesive layer 130 is for sealing the injection hole 105 formed in a part of the outer skin 100 .

That is, the UV adhesive layer 130 is formed by applying a UV adhesive to block the injection hole 105 in the cosmetic container after filling the filler 110 and curing it with UV rays.

In this case, the UV adhesive layer 130 is formed on at least a portion of the surface of the outer skin 100 of the cosmetic ball 10 . It may be formed only around the injection hole 105 to block only the injection hole 105 as in FIG. 1 .

The plasma surface treatment layer 120 is formed to increase the adhesion of the UV adhesive layer 130 between the outer skin 100 and the UV adhesive layer 130 . That is, the surface of the cosmetic container formed of the outer skin 100 is treated with plasma to increase adhesion.

The plasma surface treatment layer 120 is generated by surface treatment with atmospheric pressure plasma. The plasma surface treatment layer 120 may be formed on at least a portion of the surface of the outer skin 100 .

4 is a flowchart of a method of manufacturing a cosmetic ball according to an embodiment of the present invention.

The cosmetic ball manufacturing method according to an embodiment is driven by a cosmetic ball manufacturing process control system.

In one embodiment, the cosmetic ball manufacturing process control system transmits a control signal to at least one of a direct blow molding machine, a 3-axis robot of a filling tool and a dispensing system, a jig transfer system, and a conveyor system to control the operation. .

A method of manufacturing a cosmetic ball according to an embodiment is a method of making a sealed hollow biodegradable plastic ball (10 mm to 20 mm in diameter), injecting the cosmetic contents, and sealing the inlet to make disposable cosmetics.

The existing cosmetic manufacturing method is a method of putting the contents into a container using a nozzle or other filling tool while the entrance into which the contents can be put is opened, and then sealing the entrance with a lid or other method.

However, the manufacturing method of the cosmetic ball according to the present invention is a method for producing a cosmetic ball by directly filling a hollow molded circular ball without a completely sealed entrance by using a filling mechanism such as a syringe to pierce the shell and block the entrance.

First, the manufacturing process control system of the cosmetic ball forms a hollow sealed space in a blow molding method using the outer skin, which is a biodegradable material (S400).

In one embodiment, the outer skin should have elasticity enough to contain the cosmetic contents and squeeze the contents when used. In addition, the cosmetic contents and the outer skin must be chemically stable, and it is preferable to be implemented with a material that does not elute through the outer skin even when the cosmetic contents are stored for a long time.

In addition, according to an embodiment, the outer skin is implemented with a material that is biodegradable in nature or a material of vegetable plastic that can reduce Co2 when buried. At this time, the thickness of the outer shell can be arbitrarily adjusted to give elasticity so that the contents can easily elute when the container is punctured with a pin to use the cosmetic ball.

The manufacturing step of the shell is to make a special mold that can be molded to make a hollow sealed shell, and a direct blow molding machine makes it completely sealed with the above-mentioned material.

Thereafter, the plurality of outer skins are fixed to the jig (S410), and the plurality of outer skins are transferred to the filling process position in a fixed jig unit (S420).

At this time, for example, make a jig in the shape of about 20 horizontal lines and 20 vertical lines, put the outer skin on the jig, and close the lid so that the outer skin does not move and fix it.

Placing the outer skin in the form of a plastic ball on the jig can be done manually or through an automated process. In the case of an automated process, it may be performed by a vibration method or a vacuum method.

The lid of the jig is made slightly smaller than that of the outer skin according to the size of the outer skin and is fixed with a fixing device so that the outer skins fixed to the jig do not shake during transport to other processes.

And the filling is filled in the closed space formed by forming an injection hole in a part of the outer skin (S430).

Specifically, an injection hole is formed by applying pressure to a portion of the outer skin with a filling device, and the filling device is inserted into the closed space created by the outer skin through the formed injection hole to fill the filling.

The conveyor system transports the jig containing the outer skin to the location where the filling machine is located. The filling machine is a combination of a 3-axis robot and a dispensing system, and the dispensing valve includes a volume valve capable of discharging a certain amount and a special needle-shaped nozzle that can penetrate the plastic ball, that is, the outer skin of the valve discharging part, that is, a filling mechanism. .

When injecting the contents through the nozzle into a closed space, the filling speed may be slow due to the closed structure. This phenomenon can be achieved by changing the structure of the nozzle, that is, the filling mechanism, so that as much air as the filling amount is discharged through the nozzle at the same time, the speed and accuracy of filling the contents in an enclosed space can be increased.

According to one embodiment, in a method that can fill a completely enclosed space with plastic, a filling hole is forcibly made in the outer skin of the plastic material through a nozzle such as a syringe needle from the outside of the outer skin, that is, a filling device is injected inside.

In this case, it takes a long time for the air to come out through the gap, so it takes a lot of time to fill, as it takes a lot of time to fill the needle because it takes a long time to fill the plastic space as much as the amount of air in the plastic space is discharged around the syringe needle inserted into the outer skin. Sometimes the contents come out when you take it out.

In order to eliminate this phenomenon, it is necessary to devise a method in which the amount of air is discharged at the same time as filling.

According to one aspect of the present invention to solve this problem, the filling mechanism is to discharge the air discharged by filling the filling from the closed space created by the discharge part and the outer skin for discharging the filling, as shown in FIG. Includes an air outlet for

In addition, one end surface of the filling mechanism is characterized in that it is inclined to form an injection hole by applying pressure to a part of the outer skin.

In general, when the cosmetic contents are injected into a closed space, the filling time of the contents is delayed due to the internal pressure, and it is difficult to fill the correct amount. Therefore, according to an embodiment, the filling is performed using a special nozzle in which an air discharge part capable of removing pressure to the outside is separately mounted on the nozzle part of the filling mechanism.

The 3-axis robot fills cosmetic contents on the outer skin positioned at regular intervals by a program. At this time, the filling amount may be about 0.5ml to 1ml. However, the present invention is not limited thereto.

For continuous content filling, a separate compression tank can be connected to the dispensing nozzle to continuously fill the correct amount of filling.

Thereafter, plasma surface treatment is performed on the outer surface of the outer skin of the cosmetic ball (S440). The outer skin filled with the filling, that is, the jig containing a plurality of cosmetic balls, undergoes a plasma-equipped surface treatment process.

In particular, when the outer skin is made of PE and PP series, the material has a difficult-to-adhesive property, so it facilitates adhesion by surface treatment before filling the small hole drilled due to filling, that is, the injection hole. At this time, the surface treatment method is mainly atmospheric pressure plasma.

In the surface treatment process, a 3-axis robot and a plasma generator head are combined to move a jig equipped with a plurality of cosmetic balls in the x and y axes, and surface treatment is performed on all cosmetic balls.

At this time, the distance and speed between the plasma generator head of the surface treatment machine and the cosmetic ball can be processed by programming the 3-axis robot so that the surface can be treated appropriately in consideration of the size and thickness of the cosmetic ball.

And the injection formed by applying a UV adhesive to the outer surface of the outer skin to fill the injection hole formed in a part of the outer skin (S450), and curing the outer surface of the outer skin to which the UV adhesive is applied with a UV irradiator (S460) The hole can be sealed.

In one embodiment, when the surface treatment process of the outer skin mounted on the jig is finished, the jig containing the outer skin is transferred to the sealing part by a conveyor system.

The non-contact dispensing system is a system that sprays UV adhesive while the valve and hole are separated when applying UV adhesive to the hole to fill the hole in the sealing process.

A 3-axis robot equipped with such a non-contact dispensing system sprays UV adhesive on the surface-treated outer skin and immediately attaches it with a spot UV irradiator. Since the UV adhesive is sprayed at a fast time, if there is a delay, there is a possibility that it may flow down depending on the viscosity of the UV adhesive. Adhesive in this way to prevent the adhesive from dripping.

And when the temporary bonding process is finished, the jig is cured through an irradiator that emits UV over a large area by a conveyor system.

When UV is irradiated where the UV adhesive is sprayed, the adhesive is cured and the hole is filled.

This process is a process for curing the UV adhesive in a short time by irradiating UV while transferring the jig containing a plurality of cosmetic balls to the conveyor.

In addition, the cosmetic balls collected through the curing process are transferred to the industrial inkjet printer through the conveyor system to the printing process to record the product code, date of manufacture, and manufacturer information.

In [Table 1], a moisture content reduction test was performed by filling about 0.7 ml of an essence having a moisture content of 75% in a blow-molded cosmetic ball. The cosmetic ball aimed to meet the conditions for the weight change to be within 5% per year. Weight reduction means a reduction in cosmetic content, and it can be inferred that it is the moisture contained in the cosmetic product.

A weight reduction test was performed through the following process.

1. To control the thickness when cosmetic balls are injected by blow molding, the thickness of parison is adjusted to produce balls with a weight of 0.7g to 0.9g.

2. Inject the essence with 75% moisture content into the cosmetic ball and seal it.

3. Pick 10 cosmetic balls at random from each and measure the weight on a scale using a scale of 10,000-1.

4. Set the temperature of the incubator to 40℃ and put the cosmetic ball into the incubator. One day in the incubator equals four days at room temperature.

5. Each cosmetic ball is removed from the incubator on the 6th, 14th, 28th, 48th, 56th, and 88th days and weighed.

As a result, since the loss rate is 4.4% for 88 days in the incubator, it can be inferred that about 4.4% of water is lost at 352 days, which is four times that of 88 days at room temperature.
