[0023] To better understand the features and technical contents of the present invention, please refer to the following detailed description of the present invention and the accompanying drawings, which are provided for reference and explanation only and are not intended to limit the scope of the present invention.

[0024] Hereinafter, embodiments of the present invention will be described in detail with reference to certain specific embodiments, and those skilled in the art will be able to understand the advantages and effects of the present invention based on the contents disclosed herein. The present invention can be implemented or applied in other different specific embodiments, and various modifications and changes can be made to each detail in the present specification based on different perspectives and applications, without departing from the concept of the present invention. The technical content of the present invention will be described in more detail with reference to the following embodiments, but the disclosed contents do not limit the scope of protection of the present invention. The technical content of the present invention will be described in more detail with reference to the following embodiments, but the disclosed contents do not limit the scope of protection of the present invention.

[0025] It should be understood that although the present specification may use terms such as "first," "second," and "third" to describe various elements or signals, these elements or signals are not limited by these terms. These terms are primarily used to distinguish one element from another element or one signal from another signal. Furthermore, the term "or" used in the present specification may include any one or more combinations of the associated listed items, depending on the actual situation.

[0026] [Contact lens packaging container] As shown in FIGS. 1 and 2, an embodiment of the present invention provides a contact lens packaging container 100 including a container portion 1, a surround portion 2, and a sealing portion 3. The container portion 1 is concave and is used to contain a contact lens and a buffer solution. The surround portion 2 is planar and is integrally molded around the container portion 1. The sealing portion 3 is a sealing film for packaging the contact lens and the buffer solution in the container portion 1. It is noteworthy that the contact lens packaging container 100 according to the embodiment of the present invention is colorful and can exhibit barrier properties against light of a specific wavelength.

[0027] 3, the contact lens packaging container 100 is made of a plastic material a and a pigment material b dispersed in the plastic material a. In particular, the storage section 1 and the surround section 2 of the contact lens packaging container 100 are made of the plastic material a and the pigment material b dispersed in the plastic material a.

[0028] In particular, the contact lens packaging container 100 has special optical properties, i.e., the light blocking rate of the packaging container 100 at wavelengths of 380 nm to 780 nm measured with a spectrophotometer is 20% or more.

[0029] Based on the above-mentioned special optical properties, the contact lens packaging container 100 is given a colorful color and exhibits a barrier ability to light of a specific wavelength.

[0030] More specifically, the light barrier rate of the contact lens packaging container is defined by the following formula:

number

[0031] It should be noted that the "average light transmittance" in this specification refers to the arithmetic mean of the light transmittance curves of the packaging container at wavelengths of 380 nm to 780 nm (for example, 380 nm, 400 nm, up to 780 nm) measured with a spectrophotometer, as shown in Figure 4.

[0032] Furthermore, the colorless packaging container that does not contain a pigment material is a normal colorless and transparent packaging container. The colorless and transparent packaging container has high light transmittance and undergoes almost no color change. That is, the light barrier rate in this specification is obtained by comparing and calculating a colored packaging container that contains a pigment material and a colorless packaging container that does not contain a pigment material.

[0033] In one embodiment of the present invention, the average light transmittance T (color) of the packaging container containing the pigment material is 5% to 50%, preferably 5% to 35%. The average light transmittance T (colorless) of the colorless packaging container not containing the pigment material is 40% to 70%, preferably 40% to 60%. The light barrier rate is 20% or more, preferably 20% to 85%.

[0034] Thus, the packaging container containing the pigment material according to the embodiment of the present invention provides protection for the active ingredients contained therein, provided that it has a certain degree of transparency. It is noteworthy that the packaging container according to the embodiment of the present invention still maintains a certain degree of transparency so that the user can see or detect the contact lens and buffer solution with a detection device.

[0035] If the light barrier rate and T(color) ranges are not within the above ranges, the contact lens packaging container may not be able to protect the active ingredients contained therein (e.g., the light barrier rate is less than 20%), or the contact lenses and buffer solution contained in the packaging container may not be visible to the user or a detection device (e.g., T(color) is less than 5%).

[0036] As shown in FIG. 2, the thickness t of the packaging container affects the light barrier rate.

[0037] In one embodiment of the present invention, the container thickness t of the packaging container is 0.4 mm (millimeter, mm) to 1.2 mm. Preferably, the container thickness t of the packaging container is 0.6 mm to 1.0 mm.

[0038] If the thickness of the packaging container is too thin (for example, less than 0.4 mm), the light barrier rate will be too low and the active ingredient may not be protected. Also, if the thickness of the packaging container is too thin, it will be easily deformed when squeezed, which will affect the appearance of the packaging container.

[0039] If the thickness of the packaging container is too thick (e.g., greater than 1.2 mm), the light barrier rate may be too high, and the contact lenses and buffer solution contained in the packaging container may not be visible to the user or the detection device.

[0040] The plastic material may be at least one of polyethylene (PE), polypropylene (PP), polystyrene (PS), and poly(methyl methacrylate) (PMMA), but the present invention is not limited thereto. If the plastic material is used for packaging containers, has transparency, and is used for storing contact lenses and buffer solutions, it is in accordance with the spirit of protection of the present invention and is within the scope of protection of the present invention.

[0041] Regarding the content of the plastic material, the mass percent concentration of the plastic material in the packaging container is 80 wt% or more, and preferably 90 wt% or more. That is, the plastic material is a base material for forming the packaging container.

[0042] The pigment material may be at least one selected from the group consisting of benzimidazolone pigments, diketopyrrolopyrrole pigments, isoindolinone pigments, azo pigments, disazo pigments, quinacridone pigments, copper phthalocyanine pigments, halogenated copper phthalocyanine pigments, and anthraquinone pigments, but the present invention is not limited thereto. Any pigment material that can impart color to a packaging container and improve the light barrier rate is in line with the spirit and scope of the present invention.

[0043] The content of the pigment material affects the light barrier rate and T (color). In one embodiment of the present invention, the mass percent concentration of the pigment material in the packaging container is 50 ppm to 0.3 wt%. If the content of the pigment material is too low (e.g., less than 50 ppm), the light barrier rate is too low and the active ingredient cannot be protected.

[0044] On the other hand, if the content of the pigment material is too high (for example, more than 0.3 wt%), the light barrier rate will be too high (or T(color) will be too low), and the contact lenses and buffer solution contained in the packaging container may not be visible to the user or a detection device.

[0045] In one embodiment of the present invention, the color of the pigment material is at least one of yellow, orange, red, magenta, purple, pink, blue, and green, but the present invention is not limited thereto.

[0046] The pigment material can be added to the plastic material in a single color, or in two or more colors, to give the packaging container different colors (e.g., yellow, orange, red, blue, or black).

[0047] In an embodiment of the present invention, the packaging container is yellow, orange, red, blue, or black, the container thickness of the packaging container for contact lenses is 0.6 mm to 1.0 mm, and the light barrier rate of the packaging container at wavelengths of 380 nm to 780 nm measured with a spectrophotometer is 20% to 85%.

[0048] More specifically, as shown in Figure 4, Figure 4 shows the light transmittance curves (%T) of packaging containers of different colors measured with a spectrophotometer at wavelengths of 380 nm to 780 nm. Table 1 below shows the average light transmittance and light barrier rate calculated from the light transmittance curves of the packaging containers of different colors in Figure 4.

[0054] The thickness of the blue sample was 0.8 mm, and the average light transmittance calculated from the light transmittance curve (%T) measured with a spectrophotometer at wavelengths of 380 nm to 780 nm was 31.7%, and the light barrier rate was 27.3%. The pigment material used in the blue sample was copper phthalocyanine pigment (Cu-Phthalocyanine), the pigment material addition amount was 0.015 wt%, and the plastic material used was polypropylene.

[0055] The black sample had a thickness of 0.8 mm, and the average light transmittance (%T) of the black sample measured at wavelengths of 380 nm to 780 nm using a spectrophotometer was calculated to be 8.4%, with a light barrier rate of 80.7%. The pigment materials used in the black sample were isoindolinone pigment, benzimidazolone pigment, diketopyrrolopyrrole pigment, copper phthalocyanine pigment, and halogenated copper phthalocyanine pigment, and the pigment materials were added in an amount of 0.075 wt% (of which the five pigment materials were each added in an amount of 0.015 wt%). The plastic material used was polypropylene.

[0056] Next, specific features of the packaging containers having different colors will be described with reference to FIG.

[0057] When the sample thickness is 0.8 mm and wavelengths of 380 nm to 780 nm are measured using a spectrophotometer, both the yellow and orange polypropylene packaging containers have a light barrier rate of 50% or more at wavelengths of 380 nm to 495 nm.

[0058] When the sample thickness is 0.8 mm and wavelengths of 380 nm to 780 nm are measured using a spectrophotometer, the red polypropylene packaging container has a light barrier rate of 50% or more at wavelengths of 495 nm to 570 nm.

[0059] When the sample thickness was 0.8 mm and wavelengths of 380 nm to 780 nm were measured using a spectrophotometer, all of the blue polypropylene packaging containers had a light barrier rate of 50% or more at wavelengths of 570 nm to 730 nm.

[0060] When the sample thickness was 0.8 mm and wavelengths of 380 nm to 780 nm were measured using a spectrophotometer, all of the black polypropylene packaging containers had a light barrier rate of 80% or more at wavelengths of 380 nm to 730 nm.

[0061] [Contact lens products] 5 and 6, an embodiment of the present invention provides a contact lens product P. The contact lens product P includes a packaging container 100, a buffer solution 200, and a contact lens 300.

[0062] As shown in Fig. 3, the packaging container 100 is formed of a plastic material a and a pigment material b dispersed in the plastic material a. The light barrier rate of the packaging container 100 at wavelengths of 380 nm to 780 nm measured with a spectrophotometer is 20% or more. The characteristics of the light barrier rate of the packaging container 100 have already been described above, so a redundant description will not be given here.

[0063] The buffer solution 200 is filled into the packaging container 100. The purpose of using the buffer solution 200 is to control the pH value and osmotic pressure. As a material, the buffer solution 200 may be, for example, a borate buffer solution or a phosphate buffer solution.

[0064] The borate buffer solution has a composition comprising water (also referred to as a balance substance), sodium chloride dispersed in the water, and a borate, the borate being at least one selected from the group consisting of boric acid and sodium tetraborate.

[0065] The phosphate buffer solution has a composition comprising water (also referred to as a balance substance), sodium chloride dispersed in the water, and a phosphate salt, and the phosphate salt is at least one selected from the group consisting of sodium monohydrogen phosphate, sodium dihydrogen phosphate, potassium monohydrogen phosphate, and potassium dihydrogen phosphate.

[0066] The contact lens 300 is placed in a packaging container 100 and immersed in a buffer solution 200. The material of the contact lens 300 may be, for example, silicone hydrogel. Silicone hydrogel improves the oxygen permeability of the lens, thereby preventing symptoms such as red eye, bloodshot eyes, and redness caused by corneal hypoxia. Alternatively, the material of the contact lens 300 may be hydrogel. Hydrogel improves the wettability and lubricity of the lens, thereby increasing the comfort of the wearer.

[0067] The contact lens product further comprises an active ingredient 400. The active ingredient 400 is present in the buffer solution 200 (see FIG. 7) and / or the lens body of the contact lens 300 (see FIG. 8).

[0068] The active ingredient 400 is at least one selected from the group consisting of vitamin ingredients, phytochemical ingredients, naturally occurring ingredients, and bioactive ingredients.

[0069] Based on the special optical properties of the packaging container 100 described above, the packaging container 100 provides protection for the active ingredient 400 (light sensitive substance) contained in the packaging container, and prevents or effectively reduces deterioration of the active ingredient 400.

[0070] [Manufacturing method for contact lens packaging containers] In an embodiment of the present invention, a method for manufacturing a contact lens is provided. It should be noted that the packaging container according to the embodiment of the present invention may be manufactured by the method, but may also be manufactured by other manufacturing methods, and the present invention is not limited thereto.

[0071] The method for manufacturing a packaging container for contact lenses includes a kneading step and a molding step. In the kneading step, a plastic material and a pigment material are mixed together and introduced into an injection molding machine screw to form a kneaded material. In the molding step, the kneaded material is filled into a cavity and cooled and hardened to form a packaging container for contact lenses. In particular, the packaging container has a light barrier rate of 20% or more at wavelengths of 380 nm to 780 nm as measured with a spectrophotometer.

[0072] More specifically, in the method for producing a packaging container for contact lenses, the pigment material can be dispersed in the plastic material by a single dispersion method or a multiple dispersion method.

[0073] In a first embodiment of this embodiment (single dispersion of pigment material), the kneading step includes adding 50 ppm to 0.3 wt% of one or more pigment materials to a plastic material (e.g., polypropylene particles), mixing the mixture in a stirrer, and then adding the mixture to an extruder to perform a first dispersion and mixing, thereby forming a kneaded material. The processing temperature of the kneaded material is 170°C to 240°C. In the molding step, the kneaded material is filled into a cavity and cooled and hardened to form a packaging container for contact lenses. That is, in the first embodiment, a packaging container is manufactured by directly using a pigment material.

[0074] In a second embodiment of this embodiment (multiple dispersion of pigment material), the kneading step includes adding 50 ppm to 0.3 wt% of one or more pigment materials and 0.05 wt% to 0.3 wt% of an antioxidant to a plastic material (e.g., polypropylene particles), conducting a first dispersion-mixing process using a rotary mixer, and then conducting a second dispersion-mixing process using a screw extruder to form a kneaded material. The processing temperature of the kneaded material is 170°C to 240°C. The strip-shaped material that has undergone the kneading reaction is cooled with water and then pelletized using a pelletizer to obtain dyed polypropylene particles. The molding step includes feeding the dyed polypropylene particles into an injection molding machine screw to conduct a third dispersion-mixing process at a screw temperature of 170°C to 240°C, and then filling the mixed material into a cavity and cooling and hardening it to form a packaging container for contact lenses. That is, in the second embodiment, the pigment material is first granulated, and then the packaging container is manufactured.

[0075] [Advantageous Effects of the Embodiments] As advantageous effects of the present invention, the contact lens packaging container and contact lens product according to the present invention have the following technical features: "the packaging container is formed of a plastic material and a pigment material dispersed in the plastic material" and "the light barrier rate of the contact lens packaging container at wavelengths of 380 nm to 780 nm measured with a spectrophotometer is 20% or more", which give the packaging container a colorful appearance and enable it to exhibit barrier properties against light of specific wavelengths.
