The present disclosure relates to a packaging case, and more particularly to a contact lens product, a packaging case thereof, and a detection method for the same.
A conventional contact lens product includes a packaging case and a contact lens that is disposed in the packaging case, and an inner surface of the packaging case has a protrusion for preventing the contact lens from being adhered thereon. However, the protrusion of the packaging case is provided without consideration for optical design, such that the protrusion is not conducive to testing of the conventional contact lens product through a corresponding optical instrument (e.g., the protrusion of the conventional contact lens product easily generates light and shadow, which may affect the optical instrument during testing).
Therefore, the inventor believes that the above-mentioned defects can be improved, and devoted themselves to research while applying scientific principles, such as to finally propose an invention that is appropriately designed and effectively improves on the above-mentioned disadvantages.

Preferably, a depth of the accommodating slot body is within a range from 3 mm to 10 mm, and a width of any one of the optical microstructures is within a range from 0.01 mm to 0.1 mm.
Preferably, the packaging case is integrally formed as a single one-piece structure, and a material of the packaging case is selected from one of poly-methyl methacrylate (PMMA), polypropylene (PP), polycarbonate (PC), polystyrene (PS), and polyethylene terephthalate (PET).

As shown in
In the present embodiment, the packaging case 1 is preferably formed integrally as a single one-piece structure, the packaging case 1 is substantially light-permeable, and a material of the packaging case 1 can be selected from one of poly-methyl methacrylate (PMMA), polypropylene (PP), polycarbonate (PC), polystyrene (PS), and polyethylene terephthalate (PET), but the present disclosure is not limited thereto. For example, in other embodiments of the present disclosure not shown in the drawings, the packaging case 1 can be formed of multiple pieces; or, the packaging case 1 can be made of other polymer materials according to design requirements.
Specifically, as shown in
Moreover, the accommodating slot body 11 in the present embodiment includes a ring-shaped segment 111 connected to the sheet body 12 and an accommodating segment 112 that is connected to the ring-shaped segment 111. An end of the ring-shaped segment 111 connected to the sheet body 12 defines an opening 113, the accommodating segment 112 is substantially a hollow hemispherical shape (e.g., a contour of the accommodating segment 112 is smaller than a hemispherical shape), and a center of the hemispherical shape of the accommodating segment 112 is located outside of a space surrounded by the accommodating slot body 11. In other words, the accommodating slot body 11 has a depth D that is within a range from 3 mm to 10 mm and that is less than a diameter of the accommodating segment 112, but the present disclosure is not limited thereto.
In addition, an outer surface 11a of the accommodating slot body 11 is a smooth and curved surface, an inner surface 11b of the accommodating slot body 11 has a plurality of optical microstructures 11c arranged thereon, and each of the optical microstructures 11c has a height-to-width ratio (H/W) being within a range from 0.01 to 0.1, whereby the accommodating slot body 11 has a first transparency. For example, a width W of any one of the optical microstructures 11c can be within a range from 0.01 mm to 0.1 mm, and a height H of any one of the optical microstructures 11c is within a range from 0.001 mm to 0.01 mm.
In summary, the optical microstructures 11c of the present embodiment distributed on the inner surface 11b have a substantially same size and a substantially same shape (e.g., any one of the optical microstructures 11c has a substantially conical shape), so that microstructures of different sizes provided according to different regions cannot correspond to the optical microstructures 11c in the present embodiment.
Specifically, the optical microstructures 11c in the present embodiment are distributed on at least 70% of an area of the inner surface 11b of the accommodating slot body 11, and the optical microstructures 11c are preferably connected to each other for being distributed on the (at least 70% of) area of the inner surface 11b of the accommodating slot body 11, but the present disclosure is not limited thereto.
In the present embodiment, the optical microstructures 11c can be arranged to outwardly extend from a center of an inner side of the accommodating segment 112 (or extend toward the opening 113), until at least 70% of the area of the inner surface 11b is distributed with the optical microstructures 11c. In other words, the optical microstructures 11c can be only distributed on the inner side of the accommodating segment 112, or the optical microstructures 11c can be mostly distributed on an entirety of the inner side of the accommodating segment 112 and an entirety of an inner side of the ring-shaped segment 111.
Moreover, a relative position between any one of the optical microstructures 11c and the inner surface 11b can be adjusted or changed according to design requirements. For example, the inner surface 11b can be one of predetermined surfaces P1, P2, P3 as shown in
The sealing layer 2 is opaque and is adhered onto the sheet body 12 for sealing the opening 113 of the accommodating slot body 11, such that the sealing layer 2 and the accommodating slot body 11 jointly define an enclosed space E surrounded thereby. The contact lens 3 and the preservation liquid 4 are located in the enclosed space E, and the contact lens product 100 has a bubble B in the enclosed space E (i.e., the accommodating slot body 11 is not fully filled with the preservation liquid 4), and at least part of the contact lens 3 is immersed in the preservation liquid 4, but the present disclosure is not limited thereto. For example, in other embodiments of the present disclosure not shown in the drawings, the enclosed space E can be provided without the bubble B.
Moreover, at least part of the optical microstructures 11c is immersed in the preservation liquid 4 for enabling a part of the accommodating slot body 11 corresponding in position thereto to be defined as a wet region R1 and to have a second transparency that is greater than the first transparency. Specifically, since the accommodating slot body 11 is formed with the optical microstructures 11c, light passing through the accommodating slot body 11 would be reflected and diffused through the optical microstructures 11c. Furthermore, a difference between a refractive index of the accommodating slot body 11 and a refractive index of the preservation liquid 4 is less than a difference between the refractive index of the accommodating slot body 11 and a refractive index of air, the height-to-width ratios of the optical microstructures 11c are close to each other, so that light passing through the wet region R1 has a fewer diffusion (i.e., the wet region R1 is conducive for light to pass directly therethrough) for enabling the wet region R1 to have the second transparency that is greater than the first transparency.
In summary, in the contact lens product 100 provided by the present embodiment, the optical microstructures 11c having the similar height-to-width ratios (e.g., 0.01 to 0.1) are arranged on the inner surface 11b of the accommodating slot body 11 for being cooperated with the preservation liquid 4, thereby enabling a transparency of the accommodating slot body 11 to be changeable between the first transparency and the second transparency, so that the accommodating slot body 11 can be selectively presented in the first transparency or the second transparency according to different conditions (e.g., different detection processes).
In order to enable the accommodating slot body 11 to be effectively presented in the first transparency or the second transparency, a distal end of any one of the optical microstructures 11c preferably excludes a flat surface, and the optical microstructures 11c are preferably distributed on the inner surface 11b of the accommodating slot body 11 in a random manner (or an irregular manner).
Moreover, through the optical microstructures 11c are arranged in the accommodating slot body 11 of the contact lens product 100 provided by the present embodiment, the inner surface 11b of the accommodating slot body 11 can be configured to prevent the contact lens 3 from being adhered thereto, thereby allowing a user to easily take out the contact lens 3 from the packaging case 1.
In addition, a part of the optical microstructures 11c is located in the bubble B for enabling a part of the accommodating slot body 11 corresponding in position thereto to be defined as a dry region R2 and to have the first transparency. In other words, any part of the inner surface 11b of the accommodating slot body 11 not being attached with the preservation liquid 4 (or any liquid) can be presented in the first transparency.
The above description describes the structure of the contact lens product 100, and the following description describes the detection method S100 being suitably applied for the contact lens product 100. In the present embodiment, the detection method S100 sequentially includes a preparing step S110, a slot detection step S130, a packaging step S150, and a lens detection step S170, but the present disclosure is not limited thereto. For example, in other embodiments of the present disclosure not shown in the drawings, the detection method S100 can be added with other steps at a suitable time according to practical requirements. The following description sequentially describes the above steps S110, S130, S150, S170 of the detection method S100.

Moreover, a part of the accommodating slot body 11 being in contact with the preservation liquid 4 is defined as the wet region R1 and has the second transparency that is greater than the first transparency. Further, the accommodating slot body 11 is not fully filled with the preservation liquid 4, so that the contact lens product 100 has the bubble B in the accommodating slot body 11, and a part of the accommodating slot body 11 being in contact with the bubble B is defined as the dry region R2 and has the first transparency.
As shown in
In summary, the accommodating slot body 11 in the detection method S100 of the present embodiment is cooperated with the preservation liquid 4 for being changeable between the first transparency and the second transparency, so that the slot detection step S130 of the detection method S100 can be implemented to the accommodating slot body 11 presented in the first transparency, and the lens detection step S170 of the detection method S100 can be implemented to the accommodating slot body 11 of the contact lens product 100 presented in the second transparency, thereby facilitating the optical instrument 200 to perform a complete detection.
In addition, in the lens detection step S170, the contact lens 3 is preferable to be entirely immersed in the preservation liquid 4, and the contact lens 3 corresponds in position to the wet region R1 of the accommodating slot body 11, so that the optical detection instrument 200 can precisely detect any defect of the contact lens 3, but the present disclosure is not limited thereto.
In conclusion, the accommodating slot body in the detection method of the present disclosure is cooperated with the preservation liquid for being changeable between the first transparency and the second transparency, so that the slot detection step of the detection method is implemented to the accommodating slot body presented in the first transparency, and the lens detection step of the detection method is implemented to the accommodating slot body of the contact lens product presented in the second transparency, thereby facilitating the optical instrument to perform a complete detection.
Moreover, in any one of the contact lens product and the packaging case provided by the present disclosure, the optical microstructures having the similar height-to-width ratios (e.g., 0.01 to 0.1) are arranged on the inner surface of the accommodating slot body for being cooperated with the preservation liquid, thereby enabling a transparency of the accommodating slot body to be changeable between the first transparency and the second transparency, so that the accommodating slot body can be selectively presented in the first transparency or the second transparency according to different conditions.
Specifically, in any one of the contact lens product and the packaging case provided by the present disclosure, the changing effect of the accommodating slot body between the first transparency and the second transparency can be further increased through the detailed structural features of the accommodating slot body (e.g., any one of the optical microstructures having a conical shape, and the optical microstructures connected to each other and distributed on the inner surface of the accommodating slot body; the width of any one of the optical microstructures being within a range from 0.01 mm to 0.1 mm).
The foregoing description of the exemplary embodiments of the disclosure has been presented only for the purposes of illustration and description and is not intended to be exhaustive or to limit the disclosure to the precise forms disclosed. Many modifications and variations are possible in light of the above teaching.
The embodiments were chosen and described in order to explain the principles of the disclosure and their practical application so as to enable others skilled in the art to utilize the disclosure and various embodiments and with various modifications as are suited to the particular use contemplated. Alternative embodiments will become apparent to those skilled in the art to which the present disclosure pertains without departing from its spirit and scope.
