Description

Background Technology

[0001] In standard contact lens packaging, the contact lens is typically placed in a molded plastic base with a cavity (or "bowl") that houses the lens with its concave side facing upwards. Therefore, the user experience of transferring a contact lens from the packaging to the eye often involves the user "scooping" the lens out of the bowl with their fingers and then flipping it over to ensure it's correctly oriented on their fingers for placement on the eye. This process requires multiple touches of the lens, which can transfer contaminants or pathogens from the hands to the lens and ultimately to the eye. This handling experience is not only unhygienic but also overly cumbersome and messy, and puts mechanical stress on the lens, which can tear, break, or deform if overhandled. While some packaging is designed with the lens convex side facing upwards to avoid the need to flip it, they often still require "scooping" the lens out of the packaging solution or otherwise manipulating the lens and / or multiple touches to achieve the transfer to the eye.

[0002] The growing awareness of eye health and the demand for a more convenient experience have created a need for contact lens packaging that enables less clutter and better hygiene during contact lens handling. Ideally, contact lens wearers would be provided with "single-touch" packaging—that is, packaging that allows them to retrieve the lens from the storage container with a single touch of one of their fingers, and then, with that single touch, correctly position the lens on their eye. In such a design, there is no need to transfer and manipulate the lens from one finger to another before placing it on the eye. Providing this single-touch packaging not only simplifies the lens preparation and attachment process; it also reduces the likelihood of the lens falling out or being exposed to additional bacteria from the wearer's other fingers during positioning and attachment to the eye, and it reduces the likelihood of touching the side of the lens intended to contact the eye.

[0003] The design of single-touch or non-touch lens packaging presents several unique challenges. Ideally, the wearer should be able to consistently position the lens against their finger during removal from the packaging, and then smoothly release the lens from the finger onto the eye. Each contact lens (both reusable and daily disposable) has its own unique surface, shape, and geometry. Finger size and the force applied by the wearer to the lens during transfer can also vary. These factors can affect the process of removing the lens from the packaging onto the finger and then onto the eye. Other considerations include: it is desirable for the wearer to be able to drain any packaging solution that may affect the lens's ability to adhere to the finger, as variations in the amount of packaging solution adhering to the lens and the packaging can influence the process of placing the lens onto the finger. It is also desirable for the packaging solution to be drained in a controlled manner, avoiding spillage. Furthermore, it is beneficial that the packaging solution remains sterile and is accessible to the wearer after opening to allow for lens rewetting or washing. Furthermore, wearers may worry about the possibility of bacteria or external products (such as cosmetics) transferring onto the contact lenses; and of course, the packaging itself should be manufactured in accordance with expected industry standards recognized by the medical and commercial provider community.

[0004] Furthermore, single-touch or non-touch packaging should ideally not lead to an excessive increase in product cost compared to current contact lens packaging, as this could potentially increase costs for the wearer population. The packaging should not make it difficult to hold the lens when removing it from the packaging. Additionally, if the packaging design maintains or even reduces the volume of solution required to encapsulate the lens, this would reduce the ecological impact of lens packaging. Similarly, it would be beneficial if the packaging could be made wholly or partially from recycled materials, and / or could be wholly or partially recyclable.

[0005] Furthermore, it is advantageous if the materials constituting the packaging have been approved by various regulatory agencies and ideally, no changes to the solution chemistry or lens composition are required. Best of all, the packaging should preferably not include any electronic or other electrical components that could adversely affect the performance of either the packaging or the lenses.

[0006] Several desirable properties make achieving the functionality of single-touch or non-touch packaging challenging, and these properties are often lacking in known attempts to manufacture single-touch packaging: i) the packaging should ideally protect the lens, i.e., it should ensure the integrity of the lens (e.g., lens shape and optical integrity) while preventing pressure or damage to the lens; ii) the lens packaging should maintain the lens's hydration during storage to preserve its properties; and iii) the lens in its packaging is preferably constructed such that it is fully immersed in the packaging solution when desired, but can be removed from such solution when ready to be transferred from the packaging; iv) the packaging should generally have a boil-resistant seal and contain both the lens and the solution; v) the packaging should preferably maintain the lens in the convex orientation desired by the wearer; vi) the lens should be positioned so that it can be easily removed by the wearer; and vii) the packaging should ideally allow the packaging solution to drain effectively from the lens before opening the packaging and removing the lens, so that it can be more easily transferred to the wearer's fingers and then to the eyes.

[0007] Known packaging designs aimed at providing reduced touch, single-touch, or no-touch orientations fail to provide one or more of the desired properties mentioned above for single-touch or no-touch packaging. For example, the packaging disclosed in WO2014 / 195588, WO2009 / 069265, and JP6339322 presents the lens in a convex, bowl-down configuration. However, the lens support structure essentially matches the shape of the contact lens, providing an undesirable contact area between the lens and the lens support. These references also fail to mention mechanisms for effectively draining solution from the lens and lens support.

[0008] US1026521B2 discloses an eye drop applicator that facilitates the measurement and accurate, efficient dispensing of medications, such as eye drops or any type of liquid medication. However, the package does not include any mechanism for storing or holding contact lenses.

[0009] The packaging disclosed in WO1999021519A1 is arranged to function as an applicator when the packaging is opened, with its concave surface formed primarily to complement the convex side of the contact lens to carry the contact lens during application; and a second portion tightly connected to the first portion when the packaging is not opened, and together with the first portion defining a chamber for storing the contact lens. However, this packaging does not disclose a mechanism that provides a lever for manipulating the cap of the packaging.

[0010] US6572165B2 discloses a manipulator for applying or removing a contact lens from a user's eye. However, the manipulator does not disclose a surface configured to rotate the cap about an axis.

[0011] US5941583A discloses a contact lens insertion and manipulation assembly. This manipulation device allows a user to remove a contact lens from a storage container without touching the lens. However, the insertion and manipulation assembly does not disclose a curved surface or surface configured to allow the cap to rotate about an axis.

[0012] The deficiencies of the prior art mentioned above are merely illustrative and not exhaustive.

[0013] Furthermore, introducing novel contact lens packaging that differs from traditional blister packaging often presents a challenge for wearers. The new form factors and patterns may not be immediately intuitive. This frequently leads to frustration during the opening process and / or lens damage or contamination. Therefore, providing contact lens packaging with visual or tactile cues to make the new packaging and opening experience more intuitive would be beneficial.

[0014] Therefore, there remains a need for contact lens packaging that provides a consistent one-touch or zero-touch lens removal experience, effective solution management, or one or a combination of the aforementioned challenges or deficiencies. Summary of the Invention

[0056] Reference will now be made in detail to the representative embodiments illustrated in the accompanying drawings, wherein reference numerals denote specific elements. The following description is not intended to limit the numerous embodiments to a single preferred embodiment. Rather, it is intended to cover alternatives, modifications, and equivalents that may be included within the spirit and scope of the embodiments defined by the appended claims.

[0057] The terms "an embodiment," "an embodiment," "some embodiments," "example embodiments," etc., used to refer to embodiments that may include specific features, structures, aspects, or characteristics, but each embodiment may not necessarily include that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, aspect, or characteristic is described in association with an embodiment, it should be understood that implementing such a feature, structure, or characteristic in association with other embodiments, whether explicitly described or not, is within the knowledge of those skilled in the art.

[0058] One or more lenses or contact lenses refer to ophthalmic devices located on the eye. They are generally hemispherical and can provide optical correction, cosmetic, UV blocking and reduction of visible light or glare, therapeutic effects (including wound healing, delivery of drugs or nutrients, diagnostic assessment or monitoring), or any combination thereof. The term lens includes soft hydrogel contact lenses, which are typically provided to consumers in a hydrated state in packaging and have a relatively low modulus, allowing them to adhere to the cornea. Contact lenses suitable for the packaging of this invention include all hydrated contact lenses, including conventional and silicone hydrogel contact lenses.

[0059] Hydrogels are hydrated crosslinked polymer systems that contain water in equilibrium and may contain at least about 25%, or at least 35%, of water in their hydrated state. Hydrogels are generally oxygen-permeable and biocompatible, making them excellent materials for the production of contact lenses.

[0060] Conventional hydrogel contact lenses do not contain silicone-containing components and typically have higher water content, lower oxygen permeability, modulus, and shape memory than silicone hydrogels. Conventional hydrogels are prepared from monomer mixtures primarily composed of hydrophilic monomers, such as hydroxyethyl 2-methacrylate (“HEMA”), N-vinylpyrrolidone (“NVP”), or polyvinyl alcohol. U.S. Patents 4,495,313, 4,889,664, and 5,039,459 disclose the composition of conventional hydrogels. Conventional hydrogels can be ionic or nonionic and include polymacon, etafilcon, nelfilcon, ocufilcon, lenefilcon, etc. The oxygen permeability of these conventional hydrogel materials is typically below 20-30 barrers.

[0061] Silicone hydrogel formulations include balafilcon, samfilcon, lotrafilcon A and B, delfilcon, galyfilcon, senofilcon A, B and C, narafilcon, comfilcon, formofilcon, riofilcon, fanfilcon, stenfilcon, somofilcon, kalifilcon, etc. "Silicone hydrogel" refers to a polymer network made of at least one hydrophilic component and at least one silicone-containing component. Silicone hydrogels can have moduli ranging from 60-200, 60-150, or 80-130 psi, and water content ranging from 20% to 60%. Examples of silicone hydrogels include acquafilcon, asmofilcon, balafilcon, comfilcon, delefilcon, enfilcon, fanfilcon, formofilcon, galyfilcon, lotrafilcon, narafilcon, riofilcon, samfilcon, senofilcon, somofilcon, and stenfilcon, verofilcon, including all their variants, and U.S. Patents 4,659,782, 4,659,783, 5,244,981, 5,314,960, 5,331,067, 5,371,147, 5,998,498, 6,087,415, 5,760,100, 5,776,999, 5,789,461, 5,849,811, and 5,965. 631, 6,367,929, 6,822,016, 6,867,245, 6,943,203, 7,247,692, 7,249,848, 7,553,880, 7,666,921, 7,786,185, 7,956,131, 8,022,158, 8,273,802, 8,399,538, 8,470,906, 8,450,387, 8,487,058, 8,50 Silica hydrogels prepared in 7,577, 8,637,621, 8,703,891, 8,937,110, 8,937,111, 8,940,812, 9,056,878, 9,057,821, 9,125,808, 9,140,825, 9156,934, 9,170,349, 9,244,196, 9,244,197, 9,260,544, 9,297,928, 9,297,929 and WO 03 / 22321, WO 2008 / 061992 and US 2010 / 0048847.The entire contents of these patents are incorporated herein by reference. Silicone hydrogels can exhibit greater shape memory compared to conventional contact lenses.

[0062] Hydrogel lenses are viscoelastic materials. Optical distortion can occur when a contact lens interacts with packaging or any air bubbles within the packaging. The degree of optical distortion and the time required for distortion to relax out are highly dependent on the chemical composition and, to a lesser extent, on the lens geometry. Compared to silicone hydrogels, conventional lens materials (such as poly(hydroxyethyl methacrylate) based lenses, like etafilcon A or polymacon) have lower loss modulus and loss factor (tan delta), and less and less severe optical distortion due to contact with packaging. The incorporation of silicone (which typically increases bulk elastic response), wetting agents such as PVP (which typically increases viscous response), or coatings of conventional hydrogel materials (which can reduce elastic response at the lens interface) can alter the viscoelastic properties of the lens. Conventional hydrogel contact lenses, as well as silicone hydrogel contact lenses with short or hard crosslinking agents and / or hardeners, have short shape memory and are less prone to deformation during storage. As used in this paper, hydrogels with high or higher shape memory exhibit optical distortion of at least approximately 0.18 after accelerated aging at 55 °C for 5 weeks, resulting from contact with air bubbles or packaging. Viscoelastic properties (including loss modulus and loss factor) can be measured using dynamic mechanical analysis.

[0063] Contact lenses can be of any geometry or diopter and are generally hemispherical, with a concave rear side that rests against the eye when in use and a convex front side that faces away from the eye and contacts the eyelid during blinking.

[0064] The center or apex of a lens is the center of its optical region. This optical region provides optical correction and can have a diameter between approximately 7 mm and approximately 10 mm. The lens periphery or edge is the edge where the front and back sides meet.

[0065] A wetted lens is the contact lens and any residual packaging solution that adheres to the contact lens after the packaging solution has been discharged. The wetted contact is the total contact area between the wetted lens and the lens support.

[0066] Embodiments may include a lens support (such as the platform described herein) surrounded by a sealable cavity, which may also be interchangeably referred to as a chamber. The cavity may have any convenient form and may include a packaging base (also interchangeably referred to as a container) and at least one lid, each of which is described in detail below. As used herein, the phrases “the lid,” “lid,” “the base,” and “base” cover both the singular and plural. The lid and packaging base are sealed to each other to form a cavity that retains contact with the lens, support, and packaging solution in a sterile state during transport and storage prior to use. The contact lens packaging is made of a material compatible with both the contact lens and the solution and resistant to boiling and bioinertness.

[0067] "Film" or "multilayer film" is a film used for sealing packaging and is often referred to as lidstock. Multilayer films used in conventional contact lens packaging can be used as a base, lid component, or both in the packaging of this invention. A multilayer film comprises multiple layers, including barrier layers (including foil layers) or coatings, sealing layers (which seal the film to the rest of the packaging), and may also include additional layers selected from peel-off initiation layers, laminated layers, and layers that improve other packaging properties such as rigidity, temperature resistance, printability, puncture resistance, resistance to water or oxygen, etc. Multilayer films form a steam-sterilizable (retortible) seal. Multilayer films may include PET, BON, or OPP film layers to increase rigidity and temperature resistance, or include EVOH or PVDC coatings to improve resistance to oxygen or water vapor.

[0068] As used in this article, “unopened” or “not in use” refers to a closed contact lens package containing the contact lens in a solution.

[0069] As used herein, “open” or “open” refers to contact lens packaging where the aseptic seal has been breached. In the context described herein, “open” extends to the state of the packaging when a user manipulates it to lift the lens from the packaging solution for transfer.

[0070] As used herein, “wearer” or “user” refers to the person who opens the contact lens packaging. A user generally refers to the person who opens the packaging and transfers the contact lens contained therein to their eyes. However, in some contexts, a user may be someone who handles the lens packaging on behalf of the wearer, such as an eye care provider (“ECP”) or another individual demonstrating or assisting the wearer.

[0071] Packaging solutions are any physiologically compatible solutions that are compatible with the chosen lens material and packaging. Packaging solutions include buffer solutions with a physiological pH, such as buffered saline solutions. Packaging solutions may contain known components, including buffer solutions, pH and tonicity modifiers, lubricants, wetting agents, nutrients, pharmaceuticals, and components of the inner coating of the packaging.

[0072] The packaging base forms the bottom of the packaging. It can be made of any material suitable for packaging medical devices, including plastics. Suitable materials include polyolefins (including polypropylene) and olefin copolymers (including COP (cyclic olefin polymers) and COC (cyclic olefin copolymers)) and mixtures thereof. The packaging lid is typically located in the upper part of the packaging and seals with the base to form a cavity for receiving at least a portion of the lens support, the lens, and the packaging solution. The lid can be made of any material suitable for packaging medical devices, including molded sheets of foil or plastic, laminated films, or plastics. Packaging that includes plastic as one structure and foil or laminated film as another structure, or packaging that includes foil or laminated film as the outer layer of both the lid and the base, is known in the art and is an example of a suitable combination.

[0073] The injection molding process and the use of materials conventionally applied to injection molding mentioned throughout this description should be understood as exemplary. Those skilled in the art will understand that other manufacturing methods are possible within the scope of the appended claims, including, but not limited to, alternative molding processes, thermoforming, 3D printing, etc. Similarly, the mentioned heat seals and heat seals are examples of embodiments described herein. Other methods of securing packaging components will be apparent to those skilled in the art, including the use of adhesives, glues, thermal bonding, welding (e.g., thermal welding, ultrasonic welding, or laser welding), or mechanical clamps, etc.

[0074] Certain aspects of this invention can be used to reduce or prevent significant optical damage to contact lenses due to internal interactions with bubbles or lens packaging, which can occur during storage or transport due to gravity or other forces (e.g., mechanical pressure applied from the outside of the packaging). As used herein, significant optical damage is defined as a root mean square (RMS) value equal to or greater than about 0.08 μm.

[0075] Refer to the attached diagram. Figure 1 The illustration shows a contact lens package 100. The package 100 is configured to provide application by a single touch from a user, such that the contact lens 101 stored in the package 100 can be removed from and applied using only a single contact with the user. Furthermore, the package 100 provides a lever for easy twisting to open the package 100. Figure 1A contact lens package 100 is shown, which includes an applicator cap 102 and a container 104, the container 104 being pivotally coupled to the cap 102. The applicator cap 102 and the container 104 are hermetically coupled together to provide a sterile internal environment between the applicator cap 102 and the container 104.

[0076] The applicator cap 102 is substantially rigid and provides a sterile enclosure when attached to the container 104. The cap 102 also provides a handle (in this particular embodiment, a helical handle) configured to allow the cap 102 to be twisted and rotated at least about the central axis 111 of the container, allowing a user to open the package 100 at least partially by twisting the cap 102. The handle also provides an interface for the user to manipulate the lens 101 without touching it. The cap 102 also provides a contact surface abutting against a concave surface of the contact lens 101, such that the contact lens 101 is at least partially held on the cap 102 by surface tension. As described in more detail below, the cap 102 includes a plurality of fins 103 and a plurality of reservoir channels 105. The fins 103 are configured to contact the concave surface of the contact lens 101, and the channels 105 are configured to hold a solution. This disclosure contemplates that the size and / or shape of the fins 103 can be selected to provide a desired amount of surface tension to hold the lens 101. The force of surface tension between the finger and the lens is roughly equal to (or slightly less than) the weight of the lens. If the lens is dabped off the inverted support, as illustrated herein (e.g., in…), Figure 5B Due to the pull of gravity, the permissible wetting contact area of ​​the lens is approximately doubled compared to a lens support used with the lens "face up". In each case, to allow for single-touch transfer, the fins should be configured such that the surface tension generated by the wetting contact area between the lens support and the lens is less than the surface tension generated between the finger and the lens during a light swipe. Additionally, the channel 105 reduces surface tension, making it easier to transfer the lens 101 from the cap 102 to the user's finger. The channels 105 are preferably made wide enough not to trap solution behind the lens, i.e., at least about 1 mm wide, and similarly, high enough so that they are self-draining and thus draw liquid away from the lens 101 during opening. Preferably, the channels are at least 2 mm high below the apex of the lens. The cap 102 includes a handle portion 106a having a first end 108a, a second end 110a, and a body 112a extending between the first end 108a and the second end 110a. The body 112a includes a first lever surface 114a and a second lever surface 116a, the second lever surface 116a being opposite to and spaced apart from the first lever surface 114a. Each lever surface 114a, 116a is configured to provide at least one lever point for applying movement of the cap 102 relative to the container 104.

[0077] exist Figure 2 In the example shown, the cap 102 also includes a spherical dome with a convex surface 113 disposed at the second end 110 of the handle portion. The convex surface 113 provides a dome-shaped surface that is formed to abut a concave surface of the contact lens 101. The surface tension between the dome-shaped surface provided by the convex surface 113 and the concave surface of the lens 101 holds the lens 101 in place. In some embodiments, the convex surface 113 includes a recess (not shown) within the center of the dome to provide a mold into which a finger may mold during a light swipe. The cap 102 also includes fins 103 that define a reservoir channel 105 in the convex surface 113 of the cap 102. Figure 2 In this arrangement, fins 103 and channels 105 are of the same size and spaced apart from each other. It should be understood that this arrangement is provided only as an example. This disclosure contemplates that the number, size, and / or shape of fins 103 and channels 105 may vary. Figure 2 The differences are illustrated. Specifically, the number, size, and / or shape of the fins 103 and channels 105 can be selected to provide a desired amount of surface tension between the lens 101 and the cap 102 to facilitate movement of the lens from the cap 102 to the user's finger. The reservoir channel 105 is configured to hold the packaged solution. Each fin 103 extends away from the handle portion 106 and includes a fin surface that forms the dome-shaped surface described above. The fins 103 extend obliquely away from the center of the convex surface 113 and extend toward the edge of the convex surface with decreasing length. For example, the fins 103 extending at the edge of the convex surface 113 are shorter than the fins 103 extending from the center of the convex surface 113.

[0078] exist Figure 3 In the example shown, cap 102 also includes multiple sealing surfaces 118a. Sealing surfaces 118a correspond to sealing surfaces 118b (described below) of container 104. Sealing surfaces 118a are configured to abut container 104 to form a sterile seal when package 100 is in a closed configuration. Figure 3 In the example shown, sealing surface 118a consists of five concentric, circular, layered surfaces extending from handle portion 106 toward the center of cap 102. However, in other examples, sealing surface 118a can be any other shape or number suitable for forming a sterile seal against container 104. In some examples, sealing surface 118a is threaded, configured to interact with corresponding grooves on container 104 to create a fluid seal. In some examples, for example in… Figure 1In the example shown, a sealing package 120 formed of aluminum foil is arranged circumferentially around the cap 102 and the container 104, thereby forming a mechanical and fluid seal between the cap 102 and the container 104. The package 120 is anisotropic, making its shear strength weaker than its longer dimensions, which causes the package 120 to tear in response to torsion of the cap 102 relative to the container 104. Figure 1 In the example shown, cap 102 is made of polypropylene. However, in other examples, the cap can be made of any other material suitable for enclosing the contact lens 101 in a sterile environment. Figure 1 In the illustrated embodiment, the circumferentially arranged seal around the cap 102 is aluminum foil. However, in other examples, the circumferentially arranged seal around the cap is waxed paper, polyester sheet, or any other material suitable for sealing the cap and container together to create a sterile environment.

[0079] Container 104 is a substantially rigid container 104, configured to surround the contact lens 101 and the packaging solution when attached to cap 102 and to maintain the contact lens 101 and the packaging solution in a sterile environment. Container 104 also provides a helical, operable handle for twisting and rotating container 104, allowing a user to open packaging 100 at least partially by twisting container 104. Figure 4 As shown, container 104 includes a reservoir 115 that can contain contact lens 101 and packaging solution. Container 104 includes a handle portion 106b and a cylindrical portion having a concave dome-shaped inner surface 107 extending away from the handle portion 106b. Preferably, the inner surface 107 includes recessed areas (e.g., ribs or channels (not shown)) to reduce the surface area between the inner surface 107 and the lens 101, such that the lens preferentially adheres to the convex surface 113. If the difference in surface area is large enough, the packaging can be opened in any orientation. Similar to the handle portion 106a of cap 102, the handle portion 106b of container 104 has a first end 108b, a second end 110b, and a body 112b extending between the first end 108b and the second end 110b. Body 112b includes a first lever surface 114b and a second lever surface 116b, the second lever surface 116b being opposite to and spaced apart from the first lever surface 114b. Each lever surface 114b, 116b is configured to provide at least one lever point for applying movement of the cap 102 relative to the container 104.

[0080] exist Figure 4 In the example shown, container 104 also includes a plurality of sealing surfaces 118b surrounding a dome-shaped inner surface 107. The sealing surfaces 118b are configured to abut cap 102 when package 100 is in a closed configuration, thereby forming a sterile seal. Figure 4In the example shown, sealing surface 118b consists of five concentric, circular, layered surfaces axially spaced apart along the dome-shaped inner surface 107. However, in other examples, the sealing surfaces can be any other shape or number suitable for forming a sterile seal against container 104. In some examples, sealing surface 118a is threaded and configured to interact with corresponding grooves on container 104, thereby creating a fluid seal. Figure 1 In the examples shown, container 104 is made of polypropylene. In some examples, cap 102 and container 104 each include layered surfaces adjacent to each other. In some other examples, cap 102 and container 104 each include interlocking threads. In some examples, cap 102 and container 104 are made of the same material, but in other examples, cap 102 and container 104 are each made of a different material.

[0081] exist Figure 1-4 In the example shown, the handle portions 106a and 106b of the cap 102 and container 104 are helical. However, in other examples, the handle portions 106a and 106b are otherwise bent or shaped to provide levers for rotating the cap 102 and container 104 relative to each other. Figure 1-4 In the example shown, each of the cap 102 and container 104 has handle portions 106a and 106b, but in other examples, only one of the cap 102 and container 104 includes a handle portion. Figure 1-4 In the examples shown, the handle portion 106a of the cap 102 and the handle portion 106b of the container 104 are each of the same shape, but in other examples, the shape of the handle portion 106a of the cap 102 differs from that of the handle portion 106b of the container 104. For example, the cap 102 and the container 104 are each formed of a uniform material—polypropylene. But in other examples, the cap 102 and the container 104 are formed of any other material suitable for supporting the contact lens 101 in a sterile environment. In some other examples, the cap 102 and the container 104 are formed of different materials, such that the cap 102 is formed of a first material and the container 104 is formed of a second material. The components described herein can be manufactured by injection molding, extrusion, 3D printing, or any other manufacturing method suitable for forming a sterile contact lens package 100.

[0082] Figure 5A This shows the user opening the description above and... Figure 1-4 The package 100 shown in the image. Figure 5AThe illustration shows a user twisting the container 104 relative to the cap 102 to open the packaging 100 by grasping the first lever surface 114a and the second lever surface 116a of the cap 102 and the first lever surface 114b and the second lever surface 116b of the container 104. For example, the user grasps one of the first lever surface 114a of the cap 102 and the first lever surface 114b of the container 104 with their index finger, and the user grasps one of the second lever surface 116a of the cap 102 and the second lever surface 116b of the container 104 with their thumb. The user twists the handle portion 106a of the cap 102 and the handle portion 106b of the container 104 to break the seal between the cap 102 and the container 104. Figure 5B The contact lens 101 is shown attached to the cap 102 by the surface tension between the convex surface of the cap 102 and the concave surface of the lens 101. The lens 101 is presented on the surface, which allows it to be transferred to the user's finger with a single touch. Figure 5C The illustration shows a user removing the cap 102 with one finger to remove the contact lens 101 from the cap 102 with a single touch. The lens 101 is precisely positioned on the user's finger in the correct orientation for insertion into the eye. The user has a point of contact with the lens 101 because the lens 101 can maintain the same orientation relative to the user's finger and be placed on the user's eye.

[0083] The concave surface of the lens shown in this example preferably allows both the fingertip and the lens to deform to match each other's shape during gentle wiping, without causing the lens to flip or be damaged due to excessive pressure during removal. Therefore, one aspect of removing the lens from this package is controlling the ratio of the contact area between the finger and the lens to the area between the lens and the lens support, such that the contact area between the finger and the lens exceeds the contact surface area of ​​the lens support on the underside of the lens. This ensures that the surface tension between the finger and the lens exceeds the surface tension between the lens and the lens support. Thus, the lens will adhere to the finger for transfer and placement on the eye.

[0084] Refer to the attached diagram. Figure 6-8 The diagram illustrates a contact lens package 600. The package 600 is formed to provide contactless application by a user. Thus, the user can apply the contact lens 101 directly to the eye by manipulating the package 600. Figure 6 A contact lens package 600 is shown, which includes an applicator cap 602 and a container 604 pivotally connected to the cap 602.

[0085] The applicator cap 602 is substantially rigid and provides a sterile enclosure when attached to the container 604. The cap 602 also provides a manipulable handle for twisting and rotating the container 604, allowing a user to twist the container 604 at least partially by twisting the cap 602. The handle also provides an interface, as described above, for the user to manipulate the lens 101 without touching it. The cap 602 also provides a sealing surface abutting against a concave surface of the contact lens 101, such that the contact lens 101 is held at least partially on the cap 602 by surface tension between the cap 602 and the lens 101. The cap 602 includes a handle portion 606 having a first end 608, a second end 610, and a body 612 extending between the first end 608 and the second end 610. The cap 602 also includes a concave circular surface 615 opposite to and spaced apart from the handle portion 606, which is positioned on the lens platform 601. The handle portion 606 is an elongated body having a substantially curved cross-section. For example, the body 612 of the handle portion 606 extends between a first end 608 and a second end 610. The body 612 of the handle portion 606 includes a curved first surface 614 and a curved second surface 616, the curved second surface 616 being opposite to and spaced apart from the curved first surface 614, thereby defining a finger receiver 611. The finger receiver 611 is an elongated curved opening extending along the handle portion 606, which at least partially encloses a finger for rotating the cap 602 relative to the container 604. Each of the curved first surface 614 and the curved second surface 616 is configured to provide at least one lever point for movement of the applicator cap 602 relative to the container 604 during application of the contact lens 101 and for manipulation of the cap 602. The cap 602 also includes a recess 605 extending away from the handle portion 606. The recess 605 is a depression in the cap 602 that is configured to receive at least a portion of the user’s fingertip, thereby allowing the user to securely position their finger in the cap 602 so as to accurately apply the contact lens 101 to the eye.

[0086] Lens platform 601 provides a contact surface with the convex surface of contact lens 101. Lens platform 601 includes a concave surface 603 about a circular portion extending from a second end 610 of handle portion 606. Concave surface 603 forms a recess that abuts against the convex surface of contact lens 101 and holds contact lens 101 in place. Surface tension between concave surface 603 and the convex surface of lens 101 holds the lens in place. Concave surface 603 is configured not to cover the entire convex surface of lens 101, allowing the lens to be released onto the eye. Preferably, concave surface 603 covers less than about 50% of the convex surface area of ​​lens 101. Concave surface 603 provides a ring sized and shaped to maintain surface tension between concave surface 603 of cap 602 and the convex surface of contact lens 101. Platform 601 includes a tapered surface 613 that tapers away from the handle portion 606, thereby providing an angled sealing surface to seal against container 604.

[0087] In some examples, the cap also includes multiple sealing surfaces. These sealing surfaces are configured to abut the container when the package is in a closed configuration, thereby forming a sterile seal. The sealing surfaces can be any other shape to form a sterile seal against the container. In some examples, the sealing surfaces are threads configured to fluidly seal against the container.

[0088] Container 604 is a substantially rigid container configured to surround the contact lens 101 and the packaging solution when attached to a cap and to maintain the contact lens 101 and the packaging solution in a sterile environment. Container 604 includes a reservoir for receiving the contact lens 101 and the packaging solution. Container 604 also includes a convex surface 607 at the base of container 604, configured to abut the concave side of the contact lens 101, thereby securing the lens 101 between container 604 and cap 602. The convex surface area preferably includes recessed areas (e.g., ribs or channels (not shown)) to reduce surface area and allow air to enter beneath the lens, thus preferentially abutting the lens against the cap. Container 604 also includes a beveled inner surface 609 configured to abut the tapered portion of the platform 601 of cap 602, thereby forming a sterile seal.

[0089] In some examples, the container also includes multiple sealing surfaces surrounding the dome-shaped inner surface. These sealing surfaces are configured to abut the cap when package 600 is in the closed configuration, thereby forming a sterile seal. The sealing surfaces can be of any shape or number suitable for forming a sterile seal against container 604. In some examples, for instance... Figure 6In the example shown, a sealing package 120 formed of aluminum foil is provided and arranged circumferentially around the cap 602 and container 604, thereby forming a mechanical and fluid seal against the cap 602 and container 604. The package 620 is anisotropic, making its torsion weaker than in each of its longer dimensions, which causes the package 620 to tear in response to the torsion of the cap 602 relative to the container 604. Figure 6 In the examples shown, container 604 is made of polypropylene. In some examples, the cap and container each include layered surfaces adjacent to each other. In some other examples, the cap and container each include interlocking threads. In some examples, the cap and container are made of the same material, but in other examples, the cap and container are each made of a different material.

[0090] exist Figure 6-9 In the example shown, the handle portion 606 of the cap 602 is curved and tapers away from the concave surface of the cap 602. However, in other examples, the handle portion 606 has a uniformly curved shape, adapted to provide a lever for rotation of the cap 602 and the container 604 relative to each other. Figure 6-9 In the example shown, cap 602 has a handle portion 606 and container 604 does not have a handle portion 606. However, in other examples, both cap 602 and container 604 include a handle portion 606, which may be the same shape as each other. In other examples, the shape of the handle portion 606 of cap 602 differs from that of the handle portion 606 of container 604. For example, cap 602 and container 604 are each formed of a uniform material—polypropylene. But in other examples, cap 602 and container 604 are formed of any other material suitable for enclosing contact lens 101 in a sterile environment. In some other examples, cap 602 and container 604 are formed of different materials, such that cap 602 is formed of a first material and container 604 is formed of a second material. Figure 6 In the example shown, the circumferentially arranged sealing wrap 620 around the cap 602 is aluminum foil. However, in other examples, the circumferentially arranged sealing wrap 620 around the cap 602 is waxed paper, polyester sheet, or any other material suitable for sealing the cap 602 and container 604 together to form a sterile environment. The components described herein can be manufactured by injection molding, extrusion, 3D printing, or any other manufacturing method suitable for forming a sterile contact lens package 600.

[0091] Figure 10A This shows the user opening the description above and... Figure 6-9 The package shown is 600. Figure 10AThe illustration shows a user twisting open the package 600 by grasping the curved first surface 614 and the curved second surface of the cap 602 with one hand and the container 604 with the other. The user grasps one of the curved first surface 614 or the curved second surface 616 of the cap 602 with their index finger, and the user grasps one of the curved first surface 614 or the curved second surface 616 of the cap 602 with their thumb. The user's thumb is in the elongated curved opening, allowing the user to touch the curved surface of the curved handle. The user twists the handle portion 606 of the cap 602 and the handle portion 606 of the container 604 to break the sealing package 620 between the cap 602 and the container 604. Figure 10B The user further pulls down the handle portion 606 relative to the container 604, causing the cap 602 to rotate about the edge of the container 604. Figure 10B It is also shown that the contact lens 101 is still attached to the cap 602 by the surface tension between the concave surface of the cap 602 and the convex surface of the lens 101, thereby holding the lens 101 in place on the cap 602. Figure 10C The illustration shows a user applying lens 101 to their eye using cap 602 (i.e., without touching). Lens 101 is applied to the user's eye using a curved handle, ensuring the user never actually touches the surface of lens 101. Lens 101 is applied directly to the user's eye from cap 602. Once lens 101 is attached to the user's eye, the fluid seal between lens 101 and cap 602 is broken.

[0092] The concave portion of the lens shown in this example preferably allows for the application of the contact lens without causing the lens to flip or be damaged during removal due to excessive pressure applied during application. Therefore, one aspect of removing the lens from this package is providing an application surface that is coupled to the contact lens and can be detached from the contact lens without the user touching it. This ensures that the surface tension between the eye and the lens exceeds the surface tension between the lens and the lens cap. Thus, the lens will adhere to the eye for transfer and placement on the eye.

[0093] The visual and tactile cues disclosed herein may be particularly important for the novel contact lens packaging of this invention, which differs significantly from conventional contact lens packaging in both form and opening method. In conventional packaging, the contact lens is placed in a molded plastic base with a bowl-shaped, concave, bowl-upward position to receive the contact lens. The addition of visual or tactile features creates a more intuitive opening experience for the wearer.
