Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transparent container for protecting ultraviolet rays and infrared rays,

The present invention relates to a transparent container capable of selectively transmitting light and a method of manufacturing the transparent container.

The light emitted from the sun or the like can be classified into ultraviolet rays, visible rays and infrared rays depending on wavelengths. Here, the wavelength of the ultraviolet ray may be 280 nm to 400 nm. The wavelength of the visible light ray may be 400 nm to 750 nm. The wavelength of the infrared ray may be 750 nm to 1 mm. At this time, infrared rays may include near-infrared rays, medium-infrared rays, and thermal infrared rays.

When light such as ultraviolet rays or infrared rays is transmitted through the transparent container, the cosmetic composition inside the transparent container may be deteriorated. In addition, when light such as visible light is not transmitted through the transparent container, it may be difficult to confirm the contents inside the container.

On the other hand, heat from infrared rays or other heat sources may be a cause of deterioration of the cosmetic composition inside the transparent container.

That is, in order to prevent alteration or denaturation of the cosmetic composition, selective transmission of light and blockage of heat by a container containing the cosmetic composition are required.

In particular, a cosmetic composition containing a functional material can be deteriorated by light or heat, which makes it difficult to use a transparent container.

In detail, retinol and retinol derivatives having anti-aging function can be degraded by the external environment caused by light or heat. In addition, vitamin C and vitamin C derivatives having a whitening function, and various natural extracts which are whitening active ingredients, can be altered by the external environment caused by light or heat.

Therefore, a transparent container is limitedly used in a cosmetic composition containing a non-functional raw material.

However, the transparent container is advantageous in that stability and convenience of the user can be improved in that the remaining amount of the contents in the container can be easily confirmed, and the contents can be visibly changed.

Accordingly, there is a need for a transparent container which has transparency to the extent that contents can be confirmed, and which can block ultraviolet rays and infrared rays to secure the stability of contents.

Embodiments relate to a transparent container capable of selectively transmitting light and a method of manufacturing the transparent container. In detail, the embodiment relates to a transparent container through which visible light is transmitted, and ultraviolet rays and infrared rays can be blocked at the same time, and a manufacturing method thereof.

In a transparent container for storing a cosmetic composition according to an embodiment, the transparent container for blocking ultraviolet rays and infrared rays may include a synthetic resin, an ultraviolet screening agent, and an infrared ray blocking agent, wherein the ultraviolet ray blocking agent is an organic substance and the infrared ray blocking agent is an inorganic substance .

In a transparent container for storing a cosmetic composition according to an embodiment, a method for preparing a transparent container for ultraviolet and infrared rays shielding comprises: preparing a first master batch including a synthetic resin; Preparing a second master batch including the synthetic resin and an ultraviolet screening agent; A third master batch preparation step including the synthetic resin and the infrared blocking agent; Mixing the first master batch, the second master batch and the third master batch; And a molding step of molding the first master batch, the second master batch and the third master batch which are mixed.

The transparent container for blocking ultraviolet rays and infrared rays according to an embodiment may include both an organic-based ultraviolet ray blocking agent and an inorganic-based infrared ray blocking agent, and may have a ultraviolet ray blocking rate of 99% or more and an infrared ray blocking rate of 40% or more.

That is, the transparent container for ultraviolet and infrared ray shielding according to the embodiment can prevent deterioration of the cosmetic composition in the transparent container by ultraviolet rays and infrared rays. Thus, the stability of the contents in the transparent container can be maintained.

In addition, the transparent container for blocking ultraviolet rays and infrared rays according to the embodiment may have a visible light transmittance of 30% or more, so that the contents can be visually confirmed. Thus, the convenience of the user and the stability of the user can be improved.

The transparent container for blocking ultraviolet rays and infrared rays according to the embodiment comprises a first masterbatch processed with a synthetic resin, a second masterbatch prepared by mixing an ultraviolet screening agent with a synthetic resin of the same kind as that of the first masterbatch, A third master batch obtained by mixing an infrared blocking agent with a synthetic resin of the same kind as the master batch, and mixing the processed third master batch and molding. The first masterbatch, the second masterbatch, and the third masterbatch may contain the same synthetic resin, thereby enhancing the dispersibility of the ultraviolet screening agent and the infrared screening agent in the transparent container. Accordingly, the method for producing a transparent container for ultraviolet and infrared ray shielding according to the embodiment can produce a transparent container having a uniform ultraviolet ray, an infrared ray blocking rate, and a visible light transmittance with high yield.

Hereinafter, the present invention will be described in more detail with reference to Examples. These examples are for further illustrating the present invention, and the scope of the present invention is not limited by these examples.

A container capable of containing the cosmetic composition is used for storing the cosmetic composition. There is a risk that the cosmetic composition may be deteriorated by natural light and / or indoor light depending on the use environment of the user of the cosmetic, or the cosmetic composition may be deteriorated according to the external temperature at which the cosmetic is stored. Accordingly, the change in physical properties of the cosmetic composition can cause skin troubles, which can be a harmful factor to the human body. Therefore, it is important to prevent degeneration of the cosmetic composition and to stably store the cosmetic composition.

In particular, a functional raw material for the purpose of skin whitening and skin wrinkle improvement, which can be contained in a cosmetic composition, is characterized by being easily modified by light and / or heat.

Therefore, cosmetic compositions containing a functional ingredient are generally stored in an opaque container. These opaque containers are less convenient for the user since it is difficult to confirm the remaining amount of the contents. In addition, the user has difficulty in visually confirming changes in appearance such as color change of the contents in the opaque container, so that the convenience of the user is low and it is difficult to visually confirm the alteration of contents.

In order to solve such a problem, a transparent container capable of blocking ultraviolet rays and infrared rays and securing a visible light transmittance is required.

Conventionally, there has been developed a cosmetic container for selective light transmission. Korean Utility Model Registration No. 20-0463136 discloses a cosmetic container that simultaneously attaches a polarizing film and satisfies the content protection effect and the content identification of ultraviolet rays and visible rays. However, the Korean Registered Utility Model No. 20-0463136 requires a process of attaching at least one pair of polarizing films to the outer peripheral portion of the transparent inner container. In other words, since a separate step of attaching the polarizing film is added after the transparent container manufacturing step, the process cost may be high and the process efficiency may be low. In addition, since the transparency is determined according to the direction in which the inner polarizing film and the outer polarizing film are disposed, the product defective rate due to the tolerance may be high, resulting in a problem of lowered manufacturing yield.

Most of the cosmetic containers such as the pre-registration registered utility model are intended to block ultraviolet rays, ultraviolet rays and visible rays, and development of a cosmetic container for the purpose of blocking infrared rays and heat is insufficient.

In addition, a number of prior patents disclose a multi-layered container in which a film layer or a coating layer capable of selectively transmitting light on a container is disposed. In detail, a number of prior patents disclose coating a container using a coating agent containing a material capable of blocking light, or attaching or adhering an ultraviolet screenable film to the container to block light. As described above, it is disadvantageous that a separate manufacturing process is required after the production of the transparent container by attaching or adhering a film agent to the container or by coating. Further, the film layer or the coating layer disposed separately on the container may be deformed by the membrane.

That is, when the transparent container itself blocks light, the process efficiency is improved and the production yield can be improved.

The inventor of the present invention has conducted studies to develop a transparent container having transparency to such an extent that the cosmetic composition contained in the transparent container can be stably stored, and the cosmetic composition can be visually confirmed. As a result, the present inventors have found that a synthetic resin, an ultraviolet screening agent and an infrared It is possible to achieve the above object, and the present invention has been completed.

In addition, the present invention relates to a transparent container having a novel structure in which the material of the transparent container itself can simultaneously block ultraviolet rays and infrared rays, and selectively transmit visible light, and a method for manufacturing the same.

The transparent container according to the present invention includes a synthetic resin, an ultraviolet screening agent and an infrared ray blocking agent.

The transparent container is intended to prevent ultraviolet rays and infrared rays to prevent deterioration of the contents that can be stored in the transparent container, thereby securing the stability of the contents. In addition, the transparent container is intended to improve the stability and convenience of the user because it can prevent deterioration of contents by visible light and has a transmittance to the extent that visual confirmation of contents can be made. In addition, the transparent container is intended to prevent deterioration of contents by heat due to thermal infrared rays and / or an external use environment, thereby securing the stability of contents.

Hereinafter, a transparent container for storing a cosmetic composition and a method for producing the transparent container will be described in detail.

The transparent container is for confirming the remaining amount of the contents and confirming whether the contents have changed.

The transparent container may be transparent or translucent. Here, translucency means transparency to the extent that the content of the content can be visually confirmed whether or not the content of the content is changed.

The transparent container may have various shapes. For example, the transparent container may not be limited to a specific shape such that the outer circumferential surface has a curved surface having a curvature, a planar shape, or both a curved surface and a plane. That is, it goes without saying that the transparent container of the present invention may have various appearance depending on the molding method. Therefore, the transparent container of the present invention can be improved in design freedom.

The transparent container may not be colored. The transparent container may be a colorless transparent container.

The transparent container may have various colors. For example, the transparent container may exhibit various colors such as a red-based color, a blue-based color, and a green-based color. In detail, the transparent container may be a variety of colored transparent containers such as a red transparent container, a blue transparent container, a green transparent container, a pink transparent container, a purple transparent container, and a light blue transparent container.

The transparent container may further include a pigment in addition to a synthetic resin, an ultraviolet screening agent and an infrared ray blocking agent so as to exhibit colors. That is, the transparent container of the present invention may have various colors as it includes a coloring material such as a pigment. Accordingly, the transparent container of the present invention can be utilized in various designs of products.

The transparent container of the embodiment can be produced in various thicknesses depending on the shape or design of the container. The thickness of the transparent container may be 0.5 mm to 3.5 mm. For example, the thickness of the transparent container may be 0.5 mm to 3 mm. For example, the thickness of the transparent container may be 1 mm to 2 mm.

If the thickness of the transparent container is less than 0.5 mm, the durability of the transparent container may be deteriorated. If the thickness of the transparent container exceeds 3.5 mm, the portability may decrease as the weight of the transparent container increases. Here, the thickness of the transparent container may mean an average thickness.

The transparent container may include a synthetic resin. That is, the transparent container may be a transparent plastic.

The synthetic resin may be a plastic having optical properties such that the content can be confirmed. The synthetic resin may have transparency to such an extent that the content can be confirmed as the visible light is transmitted by 30% or more.

The synthetic resin may have chemical resistance that can prevent deformation of the contents. Further, the synthetic resin can protect the contents from external shocks.

The synthetic resin may have excellent processing characteristics. The synthetic resin may be a thermoplastic polyester. In detail, the synthetic resin may be a thermoplastic transparent polyester resin. Accordingly, the synthetic resin exhibits sintering by heat and can be formed into various shapes.

For example, the synthetic resin may be selected from the group consisting of polyethylene terephthalate (PET), glycol-modified polyethylene terephthalate (PETG), glycol-modified polycyclohexylenedimethylene terephthalate , PCTG), polycaprolactone-co-trimethylene carbonate (PCTC), and PCTC.

Glass can be dissolved by heating at a high temperature of 1000 占 폚 or higher, and it is difficult to uniformly disperse the ultraviolet screening agent and the infrared ray blocking agent in the glass, and the ultraviolet ray blocking agent and / or the infrared ray blocking agent are difficult to maintain at a high temperature of 1000 占 폚 or more. Accordingly, a synthetic resin may be preferable for the transparent container.

That is, the transparent container of the embodiment has a degree of transparency to the extent that contents can be confirmed, has chemical resistance and impact resistance capable of stably storing contents, and may include a synthetic resin for workability.

The transparent container may contain an ultraviolet screening agent to block ultraviolet rays. That is, the transparent container may include an ultraviolet screening agent, so that ultraviolet rays can be prevented from penetrating into the transparent container by more than a predetermined amount. The ultraviolet ray blocking rate of the transparent container may be 99% or more. Thus, the cosmetic composition that can be accommodated in the transparent container can be prevented from being denatured by ultraviolet rays.

The ultraviolet screening agent may include an organic material. For example, the ultraviolet light blocking agent may be a benzotriazole based organic material. In detail, it may be an organic substance based on hydroxyphenylbenzotriazole. The benzotriazole-based ultraviolet screening agent may be suitable for processing a polyester-based synthetic resin into a substrate.

In one example, the sunscreen agent may comprise tinuvin. In detail, Phenol, 2- (2H-benzotriazol-2-yl) -4,6-bis (1-methyl-1-phenylethyl) of BASF can be used.

The ultraviolet screening agent may comprise a transparent organic material. Accordingly, the ultraviolet screening agent of the examples can be suitable for the production of a transparent container.

Alternatively, the ultraviolet screening agent may comprise a colored organic material. For example, the ultraviolet screening agent may include organic materials of white, yellow series.

The transparent container may include an infrared ray blocking agent to block infrared rays. That is, the transparent container may include an infrared ray blocking agent, so that infrared rays can be prevented from penetrating into the transparent container by more than a certain amount. The infrared ray blocking rate of the transparent container may be 40% or more. Alternatively, the infrared ray blocking rate of the transparent container may be 50% or more. Thus, the cosmetic composition that can be contained in the transparent container can be prevented from being denatured by infrared rays.

The infrared blocking agent may include an inorganic material. For example, the infrared blocking agent may be carbon black. The carbon black can lower the haze value and can be suitable for processing of a transparent container.

The carbon black may block the transfer of heat due to infrared and / or external factors into the interior of the transparent container. In addition, the carbon black may have an infrared ray and an ultraviolet ray blocking effect at the same time. Accordingly, it may be suitable for a transparent container for infrared ray and ultraviolet ray shielding.

The infrared blocking agent may be black powder. The infrared blocking agent may be spherical particles. Accordingly, the carbon black may be excellent in dispersibility with respect to the synthetic resin.

The average particle diameter of the carbon black may be 10 nm to 25 nm. For example, the average particle diameter of the carbon black may be 15 nm to 20 nm. For example, the average particle diameter of the carbon black may be 17 nm to 19 nm. The infrared blocking agent may have excellent optical properties in an average particle diameter range of 10 nm to 25 nm.

The carbon black may have a BET surface Area of from 170 m ² / g to 200 m ² / g. For example, the carbon black may have a BET surface Area of 180 m ² / g to 200 m ² / g.

For example, the carbon black may be HIBLACK 50L.

The embodiment may further include a separate additive for heat resistance.

When the transparent container containing the synthetic resin, the ultraviolet screening agent and the infrared ray blocking agent is 100% by weight, the ultraviolet ray and infrared ray blocking transparent container having a thickness of 0.5 mm to 3.5 mm contain different amounts of ultraviolet ray blocking agent and infrared ray blocking agent can do. The content of the ultraviolet screening agent in the transparent container may be larger than the content of the infrared screening agent.

When the transparent container containing the synthetic resin, the ultraviolet screening agent and the infrared screening agent is 100% by weight, the transparent container for ultraviolet ray and infrared ray shielding having a thickness of 0.5 mm to 3.5 mm may contain 0.1 to 0.2% by weight of the ultraviolet screening agent And may contain 0.00133% to 0.01% by weight of the infrared blocking agent.

In detail, in order that the thickness of the transparent container is 0.5 mm to 3.5 mm and the ultraviolet ray blocking rate is 99% or more, the visible ray transmittance is 30% or more, and the infrared ray blocking rate is 40% By weight, and an infrared blocking agent in a range of 0.00133% by weight to 0.01% by weight.

When the same amount of ultraviolet ray and infrared ray blocking agent is included, the transmittance of the visible light ray decreases as the thickness of the transparent container increases, and the ultraviolet ray and infrared ray blocking rate can be increased. On the other hand, in a transparent container having the same thickness, the visible light transmittance decreases and the ultraviolet ray and infrared blocking rate increase as the content of ultraviolet ray and infrared ray blocking agent increases.

That is, depending on the thickness of the transparent container, the content of the ultraviolet screening agent and the infrared ray blocking agent may be varied within the above range. At this time, the remaining amount excluding the ultraviolet ray blocking agent and the infrared ray blocking agent may be the amount of the synthetic resin. Here, 100% by weight of the transparent container means that the composition for the production of the transparent container containing the synthetic resin, the ultraviolet screening agent and the infrared screening agent is 100% by weight.

For example, when the transparent container containing the synthetic resin, the ultraviolet screening agent and the infrared ray blocking agent is 100% by weight, the transparent container for ultraviolet ray blocking and infrared ray shielding having a thickness of 0.5 mm to 3 mm may contain 0.1 to 0.2% By weight of the infrared blocking agent, and 0.00133% to 0.008% by weight of the infrared blocking agent.

For example, when the transparent container containing the synthetic resin, the ultraviolet ray blocking agent and the infrared ray blocking agent is 100% by weight, the transparent container for ultraviolet ray blocking and infrared ray blocking, having a thickness of 1 mm to 2 mm, %, And 0.00133% to 0.0066% by weight of the infrared blocking agent.

Hereinafter, the present invention will be described in more detail with reference to specific examples.

The embodiments of the present invention may be modified in various forms, and the scope of the present invention is not limited to the embodiments described below.

A transparent container was prepared under the same conditions as in Example 1, except that the content of the infrared blocking agent was different from that of Example 1.

At this time, the same kind of material as that of Example 1 was used for the synthetic resin, the ultraviolet screening agent and the infrared ray blocking agent.

At this time, a TiO ₂ -based material was used as the infrared blocking agent.

A transparent container was prepared under the same conditions as in Example 1, except that a transparent container was prepared using a different kind of infrared screening agent, except for the ultraviolet screening agent of Example 1.

At this time, a TiO ₂ -based material was used as the infrared blocking agent.

At this time, an Fe-Cr based material was used as the infrared ray blocking agent.

Comparative Example 6

A transparent container containing only the ultraviolet screening agent in the synthetic resin was prepared. A transparent container was prepared under the same conditions as in Example 1, except that a transparent container was prepared except for the infrared blocking agent of Example 1.

Experimental Example 1

Transmittance by wavelength band according to the thickness of the transparent container according to Examples 1 and 2 and Comparative Examples 1 to 5 was measured.

In order to confirm ultraviolet transmittance of Examples and Comparative Examples, the transmittance was measured at 380 nm. At this time, when the ultraviolet transmittance is less than 1%, - is indicated.

In order to confirm the visible light transmittances of Examples and Comparative Examples, the transmittance was measured at 550 nm. At this time, when the visible light transmittance is less than 1%, - is indicated.

In order to confirm the infrared transmittance of Examples and Comparative Examples, the transmittance was measured at 850 nm. At this time, when the infrared transmittance is less than 1%, - is indicated.

The results of measurement of the transmittance by wavelength band according to the thickness of the transparent container according to Example 1 are shown in Table 1 and Fig.

thickness 380 nm T% The T% 850 nm T% 1 mm - 60 71.1 2 mm - 40.9 56.1 3 mm - 28.6 45.6

Referring to Table 1, it can be confirmed that the ultraviolet ray blocking rate measured at 380 nm in Example 1 is 99% or more.

In Example 1, when the thickness of the transparent container is 1 mm and 2 mm, the visible light transmittance measured at 550 nm is 30% or more. In detail, when the thickness of the transparent container according to Example 1 is 1 mm to 2 mm, the visible light transmittance measured at 550 nm is 40% or more. Further, it can be seen that as the thickness of the transparent container increases, the transmittance of the visible light decreases.

In Example 1, when the thickness of the transparent container is 2 mm to 3 mm, it is found that the infrared blocking rate measured at 850 nm is 40% or more. In detail, when the thickness of the transparent container according to Example 1 is 3 mm, the infrared blocking rate measured at 850 nm is 50% or more. More specifically, when the thickness of the transparent container is 1 mm, the infrared blocking rate measured at 850 nm is 28.9%, the infrared blocking rate measured at 850 nm is 43.9% when the thickness of the transparent container is 2 mm, When the thickness is 3 mm, the infrared blocking rate measured at 850 nm is 54.4%. That is, it can be seen that the infrared blocking rate increases as the thickness of the transparent container increases.

The transparent container according to Example 1 is preferably formed to a thickness of 2 mm because the ultraviolet ray blocking rate is 99% or more, the visible light transmittance is 40% or more, and the infrared ray blocking rate is 40% or more when the thickness is 2 mm .

The results of measurement of the transmittance by wavelength band according to the thickness of the transparent container according to Example 2 are shown in Table 2 and FIG.

thickness 380 nm T% The T% 850 nm T% 1 mm - 33.5 48.9 2 mm - 15.1 30.4 3 mm - 7.1 18.9

Referring to Table 2, it can be seen that the UV blocking rate measured in Example 2 at 380 nm is 99% or more.

In Example 2, when the thickness of the transparent container is 1 mm, the visible light transmittance measured at 550 nm is 30% or more. Further, it can be seen that as the thickness of the transparent container increases, the transmittance of the visible light decreases.

In Example 2, when the thickness of the transparent container is 1 mm, the infrared blocking rate measured at 850 nm is 40% or more. In detail, when the thickness of the transparent container according to Example 2 is 1 mm, the infrared blocking rate measured at 850 nm is 50% or more. More specifically, when the thickness of the transparent container is 1 mm, the infrared blocking rate measured at 850 nm is 51.1%, the infrared blocking rate measured at 850 nm is 69.6% when the thickness of the transparent container is 2 mm, When the thickness is 3 mm, the infrared cutoff ratio measured at 850 nm is 81.1%. That is, it can be seen that the infrared blocking rate increases as the thickness of the transparent container increases.

As the content of ultraviolet ray blocking agent and infrared ray blocking agent increases, ultraviolet ray and infrared ray blocking rate may increase.

The content of the infrared ray blocking agent of Example 2 is larger than that of the infrared ray blocking agent of Example 1. Thus, it can be seen that the infrared blocking rate measured at 850 nm wavelength of Example 2 is higher than the infrared blocking rate measured at the same thickness of Example 1.

On the other hand, as the content of the ultraviolet blocking agent and / or the infrared blocking agent is increased, the transmittance of the visible ray can be reduced.

The content of the infrared ray blocking agent of Example 2 is larger than that of the infrared ray blocking agent of Example 1. Thus, it can be seen that the visible light transmittance measured at the wavelength of 550 nm of Example 2 is lower than the visible light transmittance measured at the same thickness of Example 1. [

Therefore, the thickness of a suitable transparent container may vary depending on the content of the ultraviolet screening agent and the infrared ray blocking agent. That is, the content of the ultraviolet screening agent and the infrared ray blocking agent may vary depending on the thickness of the transparent container.

The transparent container according to Example 2 is preferably formed to a thickness of 1 mm since the transparent container according to Example 2 has a UV blocking rate of 99% or more, a visible light transmittance of 30% or more, and an infrared blocking rate of 50% or more when the thickness is 1 mm .

In addition, as shown in Fig. 3, when carbon black is used as an infrared ray blocking agent, it is confirmed that the haze value is low, which is suitable for the production of a transparent container. That is, the transparent container according to the embodiment has transparency or transparency to such an extent that visual confirmation of contents in the container is possible, and thus may be suitable for manufacturing a transparent container.

The results of measurement of the transmittance by wavelength band according to the thickness of the transparent container according to Comparative Example 1 are shown in Table 3 and FIG.

thickness 380 nm T% The T% 850 nm T% 1 mm 80.0 85.9 88.2 2 mm 74.1 82.2 85.2 3 mm 65.4 75.7 79.5

Referring to Table 3, it can be seen that Comparative Example 1 has a UV blocking rate of less than 99%. Thus, it can be confirmed that the transparent container of Comparative Example 1 is not suitable for storage of the functional cosmetic composition.

Unlike Comparative Example 1, Examples 1 and 2 show that the ultraviolet ray blocking rate is 99% or more as the ultraviolet ray blocking agent is included. Thus, it can be seen that the transparent containers of Examples 1 and 2 are suitable for storage of the functional cosmetic composition.

In addition, it can be seen that the infrared ray blocking rate of Comparative Example 1 is less than 40%. Thus, it can be confirmed that the transparent container of Comparative Example 1 is not suitable for storage of the functional cosmetic composition.

Unlike the comparative example 1, the infrared ray blocking rate of the example 1 and the example 2 includes the infrared ray blocking agent, and the infrared ray blocking rate is 40% or more. Thus, it can be seen that the transparent containers of Examples 1 and 2 are suitable for storage of the functional cosmetic composition.

As shown in FIG. 5, PETG specimen was photographed on a photograph. As a result, it was confirmed that the synthetic resin of PETG was transparent, and thus, it was suitable for the production of a transparent container. That is, the specimen according to Comparative Example 1 has a transmittance or transparency to such an extent that visual confirmation of the content in the container is possible, and thus may be suitable for manufacturing a transparent container.

3 and 5, the test piece according to the embodiment can reduce the haze increase even when the ultraviolet ray blocking agent and the infrared ray blocking agent are included, . That is, it can be seen that the transmittance of the test piece according to the embodiment is not significantly lower than that of the test piece according to the comparative example 1. [

The results of measurement of the transmittance by wavelength band according to the thickness of the container according to Comparative Example 2 are shown in Table 4 and FIG.

thickness 380 nm T% The T% 850 nm T% 1 mm 36.9 39.7 40.0 2 mm 20.7 21.7 21.2 3 mm 3.2 5.2 5.8

Referring to Table 4, in Comparative Example 2, when the thickness of the container is 1 mm, the visible light transmittance measured at 550 nm is 30% or more. Also, it can be seen that as the thickness of the container increases, the transmittance of the visible light decreases.

In Comparative Example 2, the infrared ray blocking rate measured at 850 nm is 40% or more. In detail, when the thickness of the container was 1 mm, the infrared cutoff rate measured at 850 nm was 60.0%, the infrared cutoff rate measured at 850 nm was 78.8% when the thickness of the container was 2 mm, , The infrared cutoff ratio measured at 850 nm is 94.2%. That is, it can be seen that as the thickness of the container increases, the infrared blocking rate increases.

In addition, it was confirmed that the infrared ray blocking rate of TiO ₂ as the infrared ray blocking agent of Comparative Example 2 was excellent.

However, as shown in FIG. 8, in the case of using TiO ₂ as an infrared blocking agent, it can be confirmed that the haze value is not suitable for the production of a transparent container. That is, the container according to Comparative Example 2 may be difficult to visually confirm contents in the container, and may not be suitable for manufacturing a transparent container.

In contrast to FIGS. 3 and 8, it can be seen that the test piece according to the embodiment has a transmittance or transparency to such an extent that visual confirmation of contents in the container can be performed even when the test piece includes an ultraviolet screening agent and an infrared ray blocking agent. On the other hand, since the specimen including TiO ₂ according to Comparative Example 2 has a large haze increase, transparency is lower than that of the specimen according to the embodiment.

The results of measurement of the transmittance by wavelength band according to the thickness of the container according to Comparative Example 3 are shown in Table 5 and FIG.

thickness 380 nm T% The T% 850 nm T% 1 mm 18.1 18.8 18.4 2 mm 6.1 6.1 5.5 3 mm 2.5 2.3 1.9

Referring to Table 5, it can be seen that the content of the infrared ray blocking agent of Comparative Example 3 is larger than the content of the infrared ray blocking agent of Comparative Example 2. Thus, in Comparative Example 3, the visible light transmittance measured at 550 nm is less than 30% when the thickness of the container is 1 mm to 3 mm. Thus, it can be seen that it is difficult to visually check the content of the container of Comparative Example 3.

In Comparative Example 3, the infrared ray blocking rate measured at 850 nm is 40% or more. In detail, when the thickness of the container was 1 mm, the infrared cutoff ratio measured at 850 nm was 81.6%, the infrared cutoff rate measured at 850 nm was 94.5% when the thickness of the container was 2 mm, , The infrared blocking rate measured at 850 nm is 98.1%. That is, it can be seen that as the thickness of the container increases, the infrared blocking rate increases.

In addition, it was confirmed that the infrared ray blocking rate of TiO ₂ as the infrared ray blocking agent of Comparative Example 2 was excellent. However, in the case of using TiO ₂ as an infrared ray blocking agent, it was confirmed that the haze value was not suitable for the production of a transparent container. Therefore, it has been confirmed that the TiO ₂ -based infrared blocking agent is not suitable for producing a transparent container.

The results of the measurement of the transmittance by wavelength band according to the thickness of the container according to Comparative Example 4 are shown in Table 6 and FIG.

thickness 380 nm T% The T% 850 nm T% 1 mm 13.5 16.3 19.5 2 mm 3.2 4.1 5.5 3 mm 0.3 0.5 1.0

Referring to Table 6, it can be seen that the visible light transmittance of Comparative Example 4 measured at 550 nm is less than 30%. Thus, it can be seen that it is difficult to visually confirm the cosmetic composition which can be contained in the container according to the comparative example 4.

In Comparative Example 4, the infrared ray blocking rate measured at 850 nm is 40% or more. In detail, when the thickness of the container was 1 mm, the infrared cutoff ratio measured at 850 nm was 80.5%, and when the thickness of the container was 2 mm, the infrared cutoff ratio measured at 850 nm was 94.5% , The infrared blocking rate measured at 850 nm is 99.0%. That is, it can be seen that as the thickness of the container increases, the infrared blocking rate increases.

In addition, it was confirmed that Fe-Cr, which is an infrared ray blocking agent of Comparative Example 4, has an excellent infrared ray blocking rate.

However, as shown in FIG. 11, when Fe-Cr is used as an infrared ray blocking agent, it can be confirmed that the haze value is not suitable for the production of a transparent container. That is, the container according to Comparative Example 4 may be difficult to visually confirm the contents in the container, and may not be suitable for manufacturing a transparent container.

3 and 11, it can be seen that the specimen according to the embodiment has transmittance or transparency to such an extent that visual confirmation of the content in the container is possible even when the specimen includes the ultraviolet screening agent and the infrared ray blocking agent. On the other hand, the Fe-Cr-containing specimen according to the comparative example 4 has a larger haze increase and thus has lower transparency than the specimen according to the embodiment.

The results of measurement of the transmittance by wavelength band according to the thickness of the container according to Comparative Example 5 are shown in Table 7 and FIG.

thickness 380 nm T% The T% 850 nm T% 1 mm 0.6 0.8 1.2 2 mm - - - 3 mm - - -

Referring to Table 7, the content of the infrared ray blocking agent of Comparative Example 5 is larger than that of the infrared ray blocking agent of Comparative Example 4. In Comparative Example 5, the visible light transmittance measured at 550 nm is less than 30%. As a result, it can be seen that the contents of the container of Comparative Example 5 are difficult to visually confirm.

In Comparative Example 5, the infrared blocking rate measured at 850 nm is 40% or more. In detail, when the thickness of the container is 1 mm, the infrared blocking rate measured at 850 nm is 98.8%, and when the thickness of the container is 2 mm to 3 mm, the infrared blocking rate measured at 850 nm is 99.9% or more . That is, it can be seen that as the thickness of the container increases, the infrared blocking rate increases.

In addition, it was confirmed that Fe-Cr, which is an infrared ray blocking agent of Comparative Example 5, has an excellent infrared ray blocking rate. However, in the case of using Fe-Cr as an infrared ray blocking agent, it was confirmed that the haze value was not suitable for the production of a transparent container. Accordingly, it has been confirmed that the Fe-Cr infrared blocking agent is not suitable for producing a transparent container.

That is, organic transparent ultraviolet ray blocking agents and inorganic infrared ray blocking agents are suitable for a transparent container having a ultraviolet ray blocking rate of 99% or more, a visible light transmittance of 30% or more, and an infrared ray blocking rate of 40% or more, and carbon black among the inorganic infrared ray blocking agents has a low haze value Therefore, it was confirmed that it is suitable for a transparent container.

Experimental Example 2

The infrared blocking effect of the transparent containers according to Examples 1 and 2 and Comparative Example 6 was measured.

In order to confirm the infrared ray blocking rates of Examples and Comparative Examples, the distance between the infrared ray irradiator and the transparent container according to Examples 1 and 2 and Comparative Example 6 was uniformly set, and then the infrared ray was irradiated for 2 hours, The temperature change was measured.

At this time, the infrared ray irradiator used an infrared lamp of 300 W, and the temperature change of the contents in the transparent container was measured every 5 minutes with a thermometer.

The infrared irradiation test was conducted for a total of 120 minutes.

Examples 1 and 2 confirmed that the transparent container had an excellent infrared blocking effect. The difference between the temperature (T2) of the content inside the transparent container and the temperature (To) of the contents inside the transparent container before irradiation with infrared rays (? T = T2-To) Respectively.

In the transparent containers of Examples 1 and 2, the difference between the temperature (T1) of the contents inside the transparent container after irradiation with infrared rays for 60 minutes and the temperature (To) To) of less than 8 占 폚.

In other words, it was confirmed that the temperature increase of the contents inside the transparent container due to thermal infrared rays was suppressed as the transparent container according to Examples 1 and 2 included the infrared ray blocking agent.

Thus, it was confirmed that the transparent container according to the embodiment can stably store a functional cosmetic composition that can be denatured by heat, infrared rays or infrared rays. It goes without saying that the transparent container of the embodiment can stably store the general cosmetic composition in addition to various functional cosmetics including retinol and the like.

On the other hand, in the transparent container of Comparative Example 6, it was confirmed that the temperature of the contents inside the container easily increased due to infrared rays.

In the transparent container of Comparative Example 6, the difference (T = T2-To) between the temperature (T2) of the contents inside the transparent container and the contents (To) Respectively.

In the transparent container of Comparative Example 6, the difference (ΔT = T1-To) between the temperature (T1) of the content inside the transparent container and the content (To) Respectively.

That is, it was confirmed that the transparent container according to Examples 1 and 2 had a smaller temperature rise than Comparative Example 6 even though heat was continuously supplied through the infrared ray irradiator from 0 to 60 minutes. Further, the transparent container according to Examples 1 and 2 was confirmed that the temperature increase after 60 minutes of infrared irradiation was insignificant. In detail, in the transparent container according to Examples 1 and 2, it was confirmed that the temperature increase from 60 minutes after the infrared irradiation to 120 minutes after the infrared irradiation was less than 3 占 폚.

Hereinafter, a method of manufacturing a transparent container for protecting ultraviolet rays and infrared rays for storing a cosmetic composition will be described with reference to FIGS. 12 to 16. FIG.

A transparent container for ultraviolet and infrared rays shielding comprises a first master batch preparation step including a synthetic resin; Preparing a second master batch including the synthetic resin and an ultraviolet screening agent; A third master batch preparation step including the synthetic resin and the infrared blocking agent; Mixing the first master batch, the second master batch and the third master batch; And a shaping step of shaping the mixed first masterbatch, the second masterbatch, and the third masterbatch.

First, with reference to Fig. 12, the first master batch preparation step including the synthetic resin 1 will be described.

The synthetic resin 1 is a plastic. The synthetic resin 1 may be at least one of PET, PETG, PCTG and PCTC. The synthetic resin 1 may be processed into a first master batch. In detail, the first master batch preparation step including the synthetic resin 1 is a step of processing the synthetic resin 1 into a pellet.

The first master batch may further include a separate pigment for color display.

Next, with reference to FIG. 13, a second master batch preparation step including the synthetic resin and the ultraviolet screening agent will be described.

The second masterbatch may include the same synthetic resin as the synthetic resin 1 included in the first masterbatch described above.

The ultraviolet screening agent (2) may be an organic material. For example, the ultraviolet screening agent (2) may be tinuvin.

The second masterbatch is a step of dispersing the ultraviolet screening agent (2) in the synthetic resin (1) and processing the pellet. Since the ultraviolet screening agent (2) is included in the second master batch, the ultraviolet screening agent (2) may be excellent in dispersibility when processed into a transparent container.

In addition, the content of the ultraviolet screening agent contained in the second master batch can be increased or decreased by adjusting the charging ratio of the second master batch according to the thickness of the transparent container according to the embodiment. That is, depending on the thickness of the transparent container, the required ultraviolet screening agent may not be separately weighed, and the convenience of the manufacturing process may be improved. In addition, it is possible to prevent a problem caused by a decrease in the uniformity of metering or a scattering of the ultraviolet screening agent, which may occur when the ultraviolet screening agent is metered separately, so that a transparent container of uniform quality can be manufactured with high efficiency.

The second master batch may further include a separate pigment for color display.

Next, with reference to Fig. 14, the third master batch preparation step including the synthetic resin and the infrared ray blocking agent will be described.

The third masterbatch may include the same synthetic resin as the synthetic resin 1 included in the first masterbatch described above.

The infrared blocking agent (3) may be an inorganic substance. For example, the infrared blocking agent 3 may be carbon black.

The third masterbatch is a step of dispersing the infrared ray blocking agent 3 in the synthetic resin 1 and processing it into pellets. Since the infrared blocking agent 3 is included in the third master batch, the dispersibility of the infrared blocking agent 3 may be excellent when the infrared blocking agent 3 is processed into a transparent container.

In addition, the content of the infrared blocking agent included in the third master batch can be increased or decreased by adjusting the charging ratio of the third master batch according to the thickness of the transparent container according to the embodiment. That is, depending on the thickness of the transparent container, the required infrared ray blocking agent may not be weighed separately, and the convenience of the manufacturing process may be improved. In addition, it is possible to prevent problems caused by a decrease in the uniformity of the metering or the scattering of the infrared ray blocking agent, which may occur when the infrared ray blocking agent is metered separately, so that the transparent container of uniform quality can be manufactured with high efficiency.

The third master batch may further include a separate pigment for color display.

Next, referring to Fig. 15, a mixing step of mixing the first master batch, the second master batch and the third master batch will be described.

The first masterbatch, the second masterbatch, and the third masterbatch may comprise the same synthetic resin. For example, the major component of the first masterbatch, the second masterbatch, and the third masterbatch may be glycol-modified polyethylene terephthalate (PETG). Here, the main component may mean 90 wt% or more. That is, since the first, second and third master batches contain the same synthetic resin, they can have excellent processability and can improve the miscibility and / or dispersibility of the ultraviolet screening agent and the infrared ray blocking agent to the synthetic resin have.

The first master arrangement, the second master arrangement, and the third master arrangement may have the same size. In detail, the first master arrangement, the second master arrangement, and the third master arrangement may have diameters corresponding to each other.

The first master arrangement, the second master arrangement, and the third master arrangement may have the same shape. In detail, the first master arrangement, the second master arrangement, and the third master arrangement may have a ratio of the length in the longitudinal direction to the length in the transverse direction. That is, the aspect ratios of the first master arrangement, the second master arrangement, and the third master arrangement may correspond to each other.

Accordingly, the first master batch, the second master batch and the third master batch can be mixed uniformly. Herein, mixing refers to a physical to mechanical mixing, and does not mean mixing according to a chemical change.

The first master batch may be mixed with at least one of the second master batch and the third master batch at different ratios. For example, the first master batch may be mixed at a greater ratio than the second master batch. For example, the first master batch may be mixed at a greater ratio than the third master batch.

The second master batch may be mixed with the third master batch at different ratios. For example, the second masterbatch may be mixed at a greater ratio than the third masterbatch. For example, the third master batch may be mixed at a greater ratio than the second master batch.

Alternatively, the second master batch may be mixed with the third master batch in the same ratio.

Wherein the first masterbatch, the second masterbatch and the third masterbatch comprise from 0.1% to 0.2% by weight of the ultraviolet screening agent and from 0.00133% to 0.01% by weight of the infrared screening agent . For example, the first masterbatch, the second masterbatch, and the third masterbatch may comprise from 0.1% to 0.2% by weight of the ultraviolet screening agent and may comprise from 0.00133% to 0.008% by weight of the infrared screening agent So that they can be mixed. For example, the first masterbatch, the second masterbatch, and the third masterbatch may comprise from 0.1% to 0.2% by weight of the ultraviolet screening agent and may comprise from 0.00133% to 0.0066% by weight of the infrared screening agent So that they can be mixed.

Next, referring to Fig. 16, a molding step for molding the first master master batch, the second master master batch and the third master master mixed will be described.

The first master batch, the second master batch and the third master batch which are uniformly mixed can be formed into a transparent container having a specific shape as it is heated. Here, the uniform mixing means that the ultraviolet ray blocking agent and the infrared ray blocking agent are mixed so as to be evenly dispersed in the transparent container.

The forming step may be blow molding. At this time, the synthetic resin included in the first, second, and third master batches may be preferably at least one of PET, PETG, PCTG, and PCTC.

Alternatively, the molding step may be injection molding. At this time, it is preferable that the synthetic resin included in the first, second, and third master batches be PETG.

The injection molding may be a single layer injection molding. Accordingly, the transparent container of the embodiment can simultaneously block light and heat in a single layer structure.

However, the embodiment is not limited thereto, and the injection molding may be a double injection molding. By double injection, the transparent container may have a double layer structure of an inner layer and an outer layer. An air gap can be positioned between the inner layer and the outer layer, and the effect of blocking the heat supplied from the outside of the transparent container can be enhanced. At this time, the content of the ultraviolet ray and the infrared ray blocking agent in the outer layer may be higher than the content of the ultraviolet ray and the infrared ray blocking agent in the inner layer. As a result, the stability of the contents can be ensured and double ultraviolet rays and infrared rays can be blocked. On the other hand, it is needless to say that the outer layer may contain ultraviolet ray and infrared ray blocking agent.

17 is a view showing that the cosmetic composition is stored in the transparent container 10 for ultraviolet and infrared rays shielding according to the embodiment.

The transparent container 10 for blocking ultraviolet rays and infrared rays may contain 0.1 to 0.2% by weight of the ultraviolet screening agent (2) and 0.00133 to 0.01% by weight of the infrared screening agent (3). For example, the transparent container 10 for blocking ultraviolet rays and infrared rays may include 0.1 to 0.2% by weight of the ultraviolet screening agent (2) and 0.00133 to 0.008% by weight of the infrared screening agent (3). For example, the transparent container 10 for blocking ultraviolet rays and infrared rays may include 0.1 to 0.2% by weight of the ultraviolet screening agent (2) and 0.00133 to 0.0066% by weight of the infrared screening agent (3).

Further, the ultraviolet ray blocking agent and the infrared ray blocking agent can be evenly dispersed in the transparent container 10 for ultraviolet ray and infrared ray blocking. Accordingly, the transparent container of the embodiment can block 99% or more of ultraviolet rays (UV) transmitted by light. Thus, denaturation of the cosmetic composition stored in the transparent container can be prevented, and the contents can be stored stably. In addition, the transparent container of the embodiment can block more than 40% of infrared (IR) transmitted by light. Alternatively, the transparent container of the embodiment can block 50% or more of infrared (IR) transmitted by light. Thus, denaturation of the cosmetic composition stored in the transparent container can be prevented, and the contents can be stored stably. Further, the transparent container of the embodiment can transmit 30% or more of visible light Vis transmitted by light. Accordingly, the cosmetic composition stored in the transparent container can be visually confirmed.

That is, the transparent container for ultraviolet and infrared rays according to the embodiment may have a single layer structure capable of simultaneously blocking light and heat. Accordingly, the transparent container for blocking ultraviolet rays and infrared rays according to the embodiments can be made to have a small thickness. That is, in the embodiment, it is not necessary to process a separate coating agent on the transparent container, so that the inconvenience of processing due to the control of the flowability of the coating agent can be solved. In addition, the embodiment can not process the film material on the transparent container, and can have a process advantage that film adhesion or adhesive processing is not required.

In addition, the transparent container for ultraviolet and infrared ray shielding according to the embodiment can selectively transmit light, prevent change of contents by an external heat source, and can stably store the functional cosmetic composition.

In addition, the ultraviolet ray blocking agent and the infrared ray blocking agent may not be directly added to the synthetic resin as the base material. That is, the transparent container for blocking ultraviolet rays and infrared rays according to the embodiment includes a second masterbatch including a synthetic resin and an ultraviolet screening agent of the same kind as the first masterbatch as the base material, a synthetic resin of the same kind as the first masterbatch as the base material, The third master batch including the first master batch can be mixed and molded to produce a transparent container having various thicknesses with excellent quality.
