[Contact lens packaging container]

As shown in FIGS. 1 and 2 , an embodiment of the present invention provides a contact lens packaging container 100 . The packaging container 100 has a containing part 1 , a surrounding part 2 , and a packaging part 3 . The holding portion 1 is in a concave shape and is used to hold contact lenses and buffer solutions. The surrounding part 2 is flat and integrally formed around the containing part 1 . The encapsulating part 3 is an encapsulating film, which is used to encapsulate contact lenses and buffer solutions in the containing part 1 . It is worth mentioning that the contact lens packaging container 100 provided by the embodiment of the present invention can have colorful colors and can have blocking ability against light of specific wavelengths.

As shown in Fig. 3, the packaging container 100 is formed of a plastic material a and a toner material b dispersed in the plastic material a. In particular, the containing portion 1 and the surrounding portion 2 of the packaging container 100 are formed of the plastic material a and the toner material b dispersed in the plastic material a.

The packaging container 100 has a special optical property, that is, the packaging container 100 has a light blocking rate of not less than 20% in a wavelength measurement range between 380 nm and 780 nm when measured by a spectrophotometer.

Based on the above special optical characteristics, the packaging container 100 can have colorful colors and can block light of specific wavelengths.

More specifically, the light blocking rate of the packaging container is defined by the following formula:

in, is an average light transmittance of the packaging container with the toner material, and is an average light transmittance of a colorless packaging container without the toner material. Light transmittance % = (I/I ₀ )*100%, I ₀ is the intensity of incident light, and I is the intensity of outgoing light.

It should be noted that the "average light transmittance" mentioned in this article refers to the measurement of the packaging container by a spectrophotometer in the wavelength range between 380 nanometers and 780 nanometers. The light transmittance curves measured for different wavelengths (such as: 380 nanometers, 400 nanometers... to 780 nanometers) (as shown in Figure 4) are obtained by taking the arithmetic mean of the light transmittance curves.

In addition, the above-mentioned colorless packaging containers without toner materials refer to generally colorless and transparent packaging containers, which have high light transmittance and appear boring in terms of color changes. That is to say, the light blocking rate mentioned in this article is the result obtained by comparing and calculating the color packaging container with toner material and the colorless packaging container without toner material.

In some embodiments of the present invention, the average light transmittance of the packaging container having the toner material is The average light transmittance of the colorless packaging container without the toner material is between 5% and 50%, and preferably between 5% and 35%. The light blocking rate is between 40% and 70%, and preferably between 40% and 60%. Furthermore, the light blocking rate is not less than 20%, and preferably between 20% and 85%.

Thus, the packaging container with the toner material in the embodiment of the present invention can protect the active ingredients stored therein under the condition of having a certain degree of transparency. It is worth mentioning that the packaging container in the embodiment of the present invention still maintains a certain degree of transparency, so that the user or the detection instrument can observe or detect the contact lens and the buffer solution stored therein.

If the light blocking rate and If the value range of exceeds the above value range, the contact lens packaging container may not be able to protect the active ingredients stored therein (such as light blocking rate is less than 20%), or the contact lens and buffer solution stored in the packaging container may not be observed by the user or the detection instrument (such as less than 5%).

The container thickness t of the packaging container will affect the light blocking rate (as shown in FIG. 2 ).

If the thickness of the packaging container is too thin (for example, less than 0.4 mm), the light blocking rate may be too low to protect the active ingredients. In addition, the packaging container may be too thin and easily deformed when squeezed, thus affecting the appearance of the packaging container.

If the thickness of the packaging container is too thick (for example, greater than 1.2 mm), the light blocking rate may be too high, so that the contact lenses and buffer solutions stored in the packaging container cannot be observed by users or testing instruments.

In terms of the type of the plastic material, the plastic material is at least one selected from the group consisting of polyethylene (PE), polypropylene (PP), polystyrene (PS), and poly (methyl methacrylate) (PMMA), but the present invention is not limited thereto. As long as the type of the plastic material can be used to form a packaging container, has light transmittance, and can be used to store contact lenses and buffer solutions, it complies with the protection spirit of the present invention and belongs to the protection scope of the present invention.

In terms of the content range of the plastic material, the mass percentage concentration of the plastic material in the packaging container is not less than 80 wt%, and preferably not less than 90 wt%. In other words, the plastic material is the main matrix material forming the packaging container.

In terms of the material type of the toner material, the toner material is selected from at least one of the material group consisting of: Benzimidazolone, Diketopyrrolopyrrole, Isoindolinone, Azo, Disazo, Quinacridone, Cu-Phthalocyanine, Cu-Phthalocyanine (Halogenated), Anthraquinone, but the present invention is not limited thereto. As long as the material type of the toner material can be used to give the packaging container color and improve the light blocking rate, it meets the protection spirit of the present invention and belongs to the protection scope of the present invention.

The content range of the toner material will affect the light blocking rate and In some embodiments of the present invention, the toner material has a mass percentage concentration of not less than 50 ppm and not more than 0.3 wt %. If the toner material content is too low (e.g., less than 50 ppm), the light blocking rate will be too low to protect the active ingredients.

On the contrary, if the content of the toner material is too high (e.g., higher than 0.3 wt%), the light blocking rate will be too high (or would be too low) so that the contact lens and buffer solution in the packaging container could not be observed by the user or the detection equipment.

In some embodiments of the present invention, the color of the toner material is at least one of yellow, orange, red, purple, purple, pink, blue, and green, but the present invention is not limited thereto. this.

The toner material can be added to the plastic material in a single color, or two or more colors can be added to the plastic material, so that the packaging container has different colors, such as yellow, orange, red, blue, or Black…etc.
