Description

Technical Field

[0001] This utility model relates to the field of contact lens storage box technology, specifically to a non-stick, easy-to-remove PP cup for contact lens packaging. Background Technology

[0002] PP contact lens packaging cups are packaging materials made of polypropylene (PP) that contain the cavity of a contact lens. To use, add an appropriate amount of contact lens preservation solution to the cup, then place the hydrated lens inside, seal it with aluminum foil using a heat press, and then sterilize it at high temperature. To use, remove the aluminum foil, remove the lens with your fingertips or tweezers, and then insert it into the contact lens container.

[0003] Most existing PP cups use a spherical or curved design at the bottom of the cavity to conform to the curvature of the lens, meaning the concave surface of the lens is in almost complete contact with the bottom of the PP cup. Because a small amount of preservative solution inside the packaging cup creates a negative pressure zone similar to a "suction cup" between the lens and the cup wall, it is difficult for consumers to quickly remove the lens from the PP cup for wearing. Furthermore, due to the large contact area between the lens and the cup, static electricity generated during transportation and prolonged static storage of the lens can cause it to adhere tightly to the cup wall. Therefore, consumers often need to apply excessive external force to mechanically remove the lens, which can easily cause irreversible damage to the lens surface or create stress concentration points. This can lead to eye discomfort such as foreign body sensation, tearing, increased eye discharge, redness, eye pain, and decreased vision after wearing the lens, and even eye diseases such as keratitis and corneal ulcers.

[0004] Therefore, how to solve the problem of contact lens sticking to the cup and achieve convenient, safe and quick lens removal remains an issue that urgently needs improvement. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a non-stick, easy-to-remove contact lens packaging PP cup. The cup wall and the lens have a maximum of only three contact points on the longitudinal surface, transforming surface contact into point (line) contact. This design significantly reduces the probability of adhesion between the PP cup and the lens, ensuring that the lens is completely surrounded and suspended by the storage solution, thereby effectively avoiding the aforementioned problems. The specific technical solution adopted by this utility model is as follows: The non-stick, easy-to-remove contact lens packaging PP cup provided by this utility model includes an integrally molded cup box body. The cup box body includes a cup compartment for holding contact lenses. The characteristic is that after the contact lens is placed in the cup compartment, there is point contact between the contact lens and the cup compartment in the longitudinal section, and the number of contact points is at most three. There is a certain angle or gap between the edge of the contact lens and the inner wall of the cup compartment.

[0006] Preferably, in the aforementioned non-stick, easy-to-remove contact lens packaging PP cup, the cup compartment includes a cup wall and a cup bottom, the cup bottom is designed to be flat, and there is an angle of 90° to 135° between the cup wall and the cup bottom; after the contact lens is placed in the cup compartment, its curved surface makes point contact with the cup wall and the cup bottom on the longitudinal section, and there is an angle between the edge of the lens and the cup wall, the angle being not less than 15°.

[0007] In a further preferred embodiment, the aforementioned non-stick, easy-to-remove contact lens packaging PP cup has a cup wall divided into a straight wall area and an inclined wall area, with the angle between the straight wall area and the bottom of the cup being 90° and the angle between the inclined wall area and the bottom of the cup being 100° to 135°.

[0008] Preferably, in the aforementioned non-stick, easy-to-remove contact lens packaging PP cup, the size of the cup compartment is designed such that there are at least two contact points between the contact lens and the cup compartment on the longitudinal section; the height of the cup compartment is designed such that the contact lens can be completely surrounded by the preservation fluid and suspended in the cup compartment.

[0009] In a further preferred embodiment, in the aforementioned non-stick, easy-to-remove contact lens packaging PP cup, the line of intersection between the straight wall area of ​​the cup wall and the bottom of the cup is arc-shaped, the line of intersection between the sloping wall area of ​​the cup wall and the bottom of the cup is straight, and the sloping wall area accounts for no more than 1 / 2 of the entire cup wall.

[0010] The aforementioned non-stick, easy-to-remove contact lens packaging PP cup, the main body of the cup box also includes a cup panel extending outward from the cup compartment opening, the cup panel including a packaging heat-sealing area, a packaging positioning area and a packaging buffer area; the packaging heat-sealing area is arranged in a ring around the cup compartment opening for heat-pressing aluminum foil sealing; the packaging positioning area is provided with a machine positioning point for limiting the placement of contact lenses into the cup compartment; the packaging buffer area is provided with a limiting lip plate to facilitate the layout and positioning of the packaging process.

[0011] Preferably, in the aforementioned non-stick, easy-to-remove contact lens packaging PP cup, the front of the cup panel is rectangular; the packaging positioning area is located on one side of the inclined wall area, and its end is provided with an auxiliary support foot; the packaging buffer zone is arranged opposite to the packaging positioning area, and the limiting lip plate is arranged at the end of the packaging buffer zone.

[0012] In a further preferred embodiment, the aforementioned non-stick, easy-to-remove contact lens packaging PP cup has a reinforcing rib between the auxiliary support foot and the cup panel; the limiting lip plate is bent downwards based on the cup panel.

[0013] The aforementioned non-stick, easy-to-remove contact lens packaging PP cup has a sandblasted matte finish on the cup compartment and the front of the cup panel, except for the packaging heat-sealing area; the bottom of the cup compartment, the back of the cup panel, and the packaging heat-sealing area are all polished glossy.

[0014] Furthermore, the aforementioned non-stick, easy-to-remove contact lens packaging PP cup is made of PP material that is natural in color or has any color among red, orange, yellow, green, blue, black, pink, cyan, purple, or gray.

[0015] Beneficial effects: 1) This utility model of PP cup abandons the traditional spherical or arc-shaped design of PP cup that fits the curvature of the lens. Based on the state of the contact lens in the cup, the surface contact between the contact lens and the cup after it is placed in the cup is changed to point / line contact, and the number of contact points does not exceed three. The edge of the contact lens is made to have a certain angle or gap with the cup, so that consumers can easily pick it up and use it with their fingertips or tweezers.

[0016] 2) Preferably, the PP cup of this utility model is designed with a flat bottom and an angle of 90° to 135° between the cup wall and the cup bottom. This allows the curved surface of the contact lens to make point contact with the cup wall and the cup bottom in the longitudinal section after the contact lens is placed in the cup compartment. An angle exists between the edge of the lens and the cup wall, and this angle is limited to not less than 15° to ensure that consumers can operate smoothly when picking it up with their fingertips or tweezers.

[0017] 4) The PP cup of this utility model divides the cup wall into a straight wall area and an inclined wall area, increasing the cup opening area and making it easier for consumers to take out the lens; and when taking out the lens, after the lens slides to the inclined wall area, the lens can form a larger angle (about 20°) with the cup wall, which further facilitates the removal of the lens.

[0018] 5) The size of the PP cup compartment of this utility model is designed according to the size of the contact lens, ensuring that there are at least two contact points between the lens and the longitudinal section in the cup compartment, thus ensuring the stability of the contact lens in the cup compartment; the height of the cup compartment is designed so that the contact lens (B) can be completely surrounded by the storage solution and suspended in the cup compartment, avoiding the formation of a negative pressure zone between the lens and the cup wall, which would cause the lens to stick to the wall, and also reducing friction with the cup wall during transportation, which could damage the lens surface and cause frictional adsorption.

[0019] 6) The PP cup of this utility model has a positioning point on the cup panel for placing contact lenses into the cup compartment and a limiting lip plate for easy layout and positioning in the packaging process. This facilitates the smooth and accurate execution of the entire packaging process, including lens loading, sealing, and sterilization, and is conducive to the implementation of automated factory packaging. The limiting lip plate is bent downwards based on the cup panel, which facilitates the stacking of packaged products and saves space in the outer packaging. The packaging positioning area is located on one side of the inclined wall area, and its end is provided with an auxiliary support foot, which can keep the cup body in a stable rotating state during use and prevent contact lenses from slipping out of the cup compartment and causing contamination.

[0020] 7) The cup compartment and cup panel of this utility model PP cup are all sandblasted and frosted, so that the preservation liquid evenly wets the entire inner wall, ensuring that the lens is fully and evenly wrapped and avoiding adsorption; and it facilitates automatic positioning in automated production processes and avoids slipping when picking up.

[0021] 8) This utility model's PP cup is made of colorless PP material or PP material with any of the following colors: red, orange, yellow, green, blue, black, pink, cyan, purple, or gray. This not only breaks away from the monotonous appearance of traditional colorless and transparent contact lens packaging, giving the product a pleasant and diverse visual experience, but more importantly, it prevents aging damage and decreased oxygen permeability caused by ultraviolet rays, ensuring the quality and performance of the lenses during long-term storage. Simultaneously, it protects the activity of the active ingredients in the contact lens storage solution, preventing them from dissolving under specific wavelengths of light, effectively ensuring the stability of the environment inside the cup cavity.

[0024] This invention addresses the problem of lenses sticking to the PP cups used in existing contact lens packaging, making it difficult for consumers to quickly remove lenses. It provides a non-stick, easy-to-remove PP cup for convenient, safe, and quick lens removal. Research has found that traditional PP cups (a) use a spherical bottom design that fully conforms to the lens, meaning the concave surface of the lens is almost entirely in contact with the bottom of the PP cup. A small amount of preservative solution inside the cup can create a negative pressure zone, similar to a suction cup, between the lens and the cup wall, causing the lens to stick. Secondly, since both the lens and the PP cup are insulating materials prone to static electricity, the static electricity generated during transportation can cause them to adhere tightly. Long-term static contact with the cup wall during storage and transportation further exacerbates this adhesion. Meanwhile, the traditional PP cup's spherical bottom design, which fully conforms to the lens, significantly reduces contact between the lens and preservative solution during storage, further increasing the probability of adhesion between the PP cup and the lens. The design of this utility model greatly reduces the probability of adhesion between the PP cup and the lens, ensuring that the lens can be completely surrounded and suspended by the preservation liquid, thereby effectively avoiding the above-mentioned problems.

[0025] In addition, this invention also solves the problem that during long-term storage, lenses may partially detach from the storage solution, lose water, dry out, and change their hydration state, making them difficult to unfold after being folded, and causing more serious adhesion, which in severe cases leads to a decline in lens quality.

[0026] Furthermore, some contact lenses suffer from molecular chain breakage or cross-linking of the polymer material under long-term exposure to specific wavelengths of light (especially ultraviolet light), leading to material aging, brittleness, and decreased oxygen permeability. The active substances introduced into the preservation solution, such as vitamins A, B, C, E, and anthocyanins, are photosensitive and easily decompose and oxidize under light, resulting in reduced potency or even inactivation. This is also one of the problems addressed by this invention.

[0027] The technical solution of this utility model will now be clearly and completely described with reference to the embodiments and accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The specific implementation method is as follows: This utility model of a PP cup addresses the issue of contact lenses in their container by changing the surface contact between the contact lens and the container to a point / line contact, with no more than three contact points. It also establishes a certain angle or gap between the edge of the contact lens and the container, facilitating easy handling by the consumer using their fingertips or tweezers. Specifically, the non-stick, easy-to-remove contact lens packaging PP cup provided by this utility model includes an integrally molded cup body A. The cup body A includes a container 1 for holding contact lenses. When a contact lens B is placed in the container 1, it makes point contact with the container 1 in a longitudinal section, with a maximum of three contact points C. The edge of the contact lens B has a certain angle with the inner wall of the container 1.

[0029] This solution can be implemented in various ways. For example, in some embodiments, a support contact point can be set inside the cup compartment to support the lens, thereby reducing the contact area between the lens and the inner wall of the cup compartment to prevent it from sticking to the cup. This also creates a certain gap or angle between the edge of the lens and the cup wall to facilitate the removal of the lens.

[0030] In this embodiment, a novel non-stick, easy-to-remove contact lens packaging PP cup is provided. This PP cup abandons the traditional spherical or curved design that conforms to the curvature of the lens. See the specific structure below. Figures 1 to 4 In addition to the one-piece molded cup body A and the cup compartment 1 for accommodating contact lenses, the PP cup also includes the following features: First, the cup compartment 1 includes a cup wall 11 and a cup bottom 12. The cup bottom 12 is designed to be flat, and there is an angle of 90° to 135° between the cup wall 11 and the cup bottom 12. After the contact lens B is placed in the cup compartment 1, its curved surface makes point contact with the cup wall 11 and the cup bottom 12 in the longitudinal section, and there is an angle between the edge of the lens and the cup wall 11, which is not less than 15°, to ensure that the consumer can easily operate it when picking it up with their fingertips or tweezers. Furthermore, the cup wall 11 is divided into a straight wall area 111 and an inclined wall area 112. The angle between the straight wall area 111 and the cup bottom 12 is 90°, and the angle between the inclined wall area 112 and the cup bottom 12 is 100° to 135°. This not only increases the cup opening area, making it easier for the consumer to retrieve the lens, but also allows the lens to slide to the inclined wall area, where it can form a larger angle (approximately 20°) with the cup wall, further facilitating lens removal. Secondly, the size of the non-stick, easy-to-remove contact lens packaging PP cup provided in this embodiment is designed according to the size of the contact lens. Specifically, the volume of the cup compartment 1 is designed such that there are at least two contact points C between the contact lens B and the cup compartment 1 on the longitudinal section, ensuring the stability of the contact lens in the cup compartment. The height of the cup compartment 1 is designed so that the contact lens B can be completely surrounded and suspended in the cup compartment 1 by the storage solution D, avoiding the formation of a negative pressure zone between the contact lens and the cup wall, which would cause it to stick to the wall. This also reduces friction with the cup wall during transportation, preventing damage to the lens surface and frictional adhesion. At the same time, it allows the lens to be stably unfolded and fixed in the storage solution, making it less prone to folding, flipping, or sticking due to vibration during transportation and storage. Whether during daily carrying or during handling, the lens can always be stably suspended in the preset ideal state. Every time the wearer opens the package, they get a perfectly unfolded, ready-to-use lens, completely eliminating the difficulty in identification and operation caused by lens flipping, sticking, or folding due to vibration. This not only improves wearing efficiency but also protects the lens itself.

[0031] Furthermore, in the non-stick, easy-to-remove contact lens packaging PP cup described in this embodiment, the straight wall area 111 of the cup wall 11 is cylindrical, meaning the junction between it and the cup bottom 12 is arc-shaped, and a rounded chamfer is provided at the junction; the sloping wall area 112 of the cup wall 11 is a flat sloping plate, meaning the junction between it and the cup bottom 12 is straight. This design effectively increases the angle and gap between the sloping wall area 112 and the edge of the contact lens B, making it easier to pick up with fingertips or thicker tweezers. Furthermore, rounded chamfers are provided at the junctions of the sloping wall area 112 with the cup bottom 12 and with the straight wall area 111, ensuring a smooth and rounded interior to avoid damaging the lens. In addition, to ensure a harmonious cup structure and sufficient internal space, the sloping wall area 112 occupies no more than 1 / 2 of the entire cup wall 11.

[0032] In addition, the non-stick, easy-to-remove contact lens packaging PP cup described in this embodiment also includes a cup panel 2 extending outward from the opening of the cup compartment 1. The cup panel 2 includes a packaging heat-sealing area 21, a packaging positioning area 22, and a packaging buffer area 23. The packaging heat-sealing area 21 is arranged in a ring around the opening of the cup compartment 1 for sealing with heat-pressed aluminum foil E. The packaging positioning area 22 is provided with a machine positioning point 3 for limiting the placement of contact lenses B into the cup compartment 1. The packaging buffer area 23 is provided with a limiting lip plate 4 for easy layout and positioning of the packaging process. This facilitates the smooth and accurate execution of the entire packaging process, including lens loading, sealing, and sterilization, and is conducive to the implementation of automated factory packaging.

[0033] In a preferred embodiment, the non-stick, easy-to-remove contact lens packaging PP cup described in this embodiment has a rectangular front panel 2; in other embodiments, it can be designed as an oval, triangular, or other suitable shape. In this embodiment, the packaging positioning area 22 is located on one side of the inclined wall area 112, and its end is provided with an auxiliary support foot 5. A reinforcing rib 6 is provided between the auxiliary support foot 5 and the cup panel 2, which can keep the cup body in a stable rotating state during use and prevent contact lenses from slipping out of the cup compartment and causing contamination. The packaging buffer zone 23 is arranged opposite to the packaging positioning area 22, and the limiting lip plate 4 is arranged at the end of the packaging buffer zone 23 and is bent downward with the cup panel 2 as the reference, which facilitates the stacking of packaged products and saves space in the outer packaging.

[0034] Furthermore, in this embodiment, the non-stick, easy-to-remove contact lens packaging PP cup has a sandblasted matte finish on the front of the cup compartment 1 and the front of the cup panel 2, except for the packaging heat-sealing area 21; the bottom of the cup compartment 1, the back of the cup panel 2, and the packaging heat-sealing area 21 are all polished glossy. The sandblasted matte design not only eliminates reflections and facilitates machine vision inspection—on fully automated production lines, cameras need to accurately detect whether the liquid level in each cup is up to standard, whether there is a lens, and whether the sealing aluminum foil is intact—but also eliminates reflections and shadows on a smooth, glossy surface, which severely interferes with camera judgment and leads to false detections. The matte surface creates diffuse reflection and uniform light, providing a stable and reliable inspection environment for machine vision, greatly improving production efficiency and yield. It also facilitates lens removal; a smooth inner wall causes the lens to adhere tightly to the wall like a suction cup, making it difficult to pick up even with tweezers or requiring multiple attempts. The rough matte surface breaks the vacuum adhesion between the lens and the cup wall, making the lens easier to pick up with tweezers or pour into the palm of the hand, making removal easier. Meanwhile, the sandblasted matte finish design enhances handheld stability. In this embodiment, not only the inside but also the outside of the cup is often treated with a matte or frosted finish, which increases friction and prevents slippage when hands are wet or have liquid on them, allowing the wearer to hold the PP cup more securely.

[0035] Finally, the non-stick, easy-to-remove contact lens packaging PP cup described in this embodiment is made of PP material that is natural-colored or has any color among red, orange, yellow, green, blue, black, pink, cyan, purple, or gray. This breaks away from the monotonous appearance of traditional colorless and transparent contact lens packaging, giving the product a pleasant and diverse visual experience. More importantly, this design is not merely aesthetically pleasing; it possesses substantial optical functionality. For the lenses, the specific colored material used in this PP cup can precisely reflect or absorb specific wavelengths of light (such as ultraviolet light and high-energy blue light) that are harmful to the lens material, acting like an "optical filter" to block the photochemical reactions that cause material decomposition at the source. This greatly slows down the photoaging process of the lens material, ensuring that the physical properties, oxygen permeability, and wearing comfort of the lenses remain consistent throughout the entire shelf life. For the storage solution, this design, through carefully selected colorants, creates a stable cavity environment that effectively filters out specific wavelengths of light that cause the decomposition of these photosensitive substances. This allows the preservative solution inside the bottle to be stored under "light-protection" conditions, significantly maintaining the activity and stability of its functional components, thus ensuring that the preservative solution can exert its due effect when used by the wearer.

[0036] In summary, this utility model of PP cup innovatively changes the contact method between the lens and the cup compartment from the traditional large-area adhesion to a limited point / line contact. Simultaneously, it optimizes the cup's geometry, designing a flat bottom, refining the sloping wall sections, and precisely controlling the volume. This successfully solves the problem of contact lenses sticking to the cup, greatly facilitating the quick removal of lenses by consumers using their fingertips or tweezers, while maintaining the original strength and appearance of the lens material. A comparison of the cross-section of this utility model's PP cup with traditional PP cups and the clamping process are shown in [link to product description]. Figure 5 In the figures, (a) is the cross-section of a traditional PP cup, (b) is the cross-section of the PP cup of this invention, and (c) shows the process of the PP cup of this invention clamping a lens. Furthermore, the PP cup design of this invention avoids lens friction damage, facilitates automated production, and the use of colored PP material not only makes it aesthetically pleasing but also effectively blocks ultraviolet rays, protecting the long-term stability of the lens and the medication. It possesses excellent practicality and economic value, and has promising prospects for widespread application.
