Description

Contact lens packaging box for sliding or tilting lenses and processing method

The present disclosure relates to contact lens packaging boxes, methods of packaging contact lenses, and methods of opening contact lens packaging boxes.

In conventional contact lens packaging boxes, the contact lens is typically placed in a molded plastic molded plastic material that has a cavity (or "bowl") that accommodates the contact lens in a concave-side-up orientation. in the base. Therefore, the user experience of transferring contact lenses from the box to the eye generally involves the user "fishing" the contact lens from the bowl with their fingers, and then flipping the lens so that it is correctly oriented on the finger. For placement on the eyes. This procedure requires touching the lens multiple times, which can transfer contaminants or pathogens from the hands to the lens and ultimately to the eye. Not only is this handling experience unhygienic, it is also unduly cumbersome, cumbersome, and puts mechanical stress on the lens, which may tear, pull, or deform when handled excessively. Although some boxes have been designed to present the lenses in a convex-side-up orientation to avoid the need to turn the lenses over, these boxes often still require the lenses to be "removed" from the box solution or otherwise. Manipulate the lens and/or touch the lens multiple times to transfer the lens to the eye.

Growing awareness of eye health and customer demand for a more convenient experience have created a need for contact lens packaging that enables less cumbersome and more hygienic contact lens disposal procedures. In one aspect, it would be desirable to provide the contact lens wearer with a "single touch" packaging box, that is, by means of which the contact lens wearer can use one of his or her A single touch of a finger removes the lens from the lens storage box and then positions the lens correctly on the eye with a single touch. In this design, there would be no need to transfer and manipulate the lens from one finger to another before placing it on the eye. Providing this single-touch packaging will not only simplify the lens preparation and insertion process; it will also reduce the risk of the lens falling out or being exposed to the wearer's other fingers while preparing the lens for orientation and placement on the eye. The possibility of picking up additional bacteria, and it also reduces the possibility of touching the side of the lens intended to come into contact with the eye.

The design of single-touch lens packaging boxes presents some different challenges. Ideally, the wearer should be able to position the lenses consistently to adhere to their fingers during removal from the box. In addition, a single-touch packaging box should ideally not result in an excessive increase in product cost relative to current contact lens packaging boxes, as this may lead to an increase in cost for the wearer community. The box should not make it difficult to hold the lens when removing it from the box. Furthermore, if the packaging box is configured to maintain or even reduce the volume of solution required to package the lens, this will reduce the ecological impact of the lens packaging box. Similarly, it would be beneficial if all or part of the packaging box could be made from recycled materials and/or be recyclable in whole or part.

Furthermore, it would be advantageous if the packaging box was composed of materials that have been approved by various regulatory agencies and ideally would not require changes to the solution chemistry or lens composition. Also optimally, the functionality of the packaging box preferably does not incorporate any electronic or other electrical components that could adversely affect the performance of the packaging box or lenses.

Therefore, there remains a need for contact lens packaging boxes that provide a convenient lens removal experience.

These and other aspects and improvements of the present disclosure will become apparent to those of ordinary skill in the art upon review of the following embodiments, taken in conjunction with the accompanying drawings and accompanying claims.

Reference will now be made in detail to the representative embodiments illustrated in the accompanying drawings, wherein the reference numerals indicate certain 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 as may be included within the spirit and scope of the described embodiments as defined by the appended claims.

References to "one embodiment," "an embodiment," "some embodiments" and the like indicate that the described embodiments may include particular features, structures, aspects, or characteristics. However, each embodiment may not necessarily include such specific features, structures or characteristics. Furthermore, such phrases do not necessarily refer to the same embodiment. In addition, when a specific feature, structure, aspect, or characteristic is described with respect to an embodiment, it is considered herein that, whether explicitly described or not, it is within the knowledge of a person having ordinary skill in the art and therefore can be related to Other embodiments implement such features, structures, or characteristics.

As used herein, the following terms have the following meanings. A benefit of certain embodiments of the present invention is that they facilitate consistent single-touch lens transfer from the packaging box to the wearer's finger and then from the finger to the wearer's eye without causing the lens to be inverted and fall off the finger. dropped, or further manipulated. It is also desirable for the lens to "sit up" on the finger without collapsing or inverting, and then transfer to the eye when inserted into the eye. Certain embodiments of the packaging can provide desired single touch transfer under a variety of finger sizes and light touch pressures. Environmental conditions (such as temperature and whether fingers are wet or dry) can also affect transfer rates, with higher temperatures generally improving lens transfer.

Lens(s) or contact lens(s) means an ophthalmic device placed on the eye. They have a generally hemispherical shape and may provide optical correction, cosmetic enhancement, UV blocking and visible light or glare reduction, 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 a box and have a relatively low modulus, which allows the lens to conform to the cornea. Contact lenses suitable for use in the packaging of the present invention include all hydrated contact lenses, including conventional and polysilicone hydrogel contact lenses.

Hydrogels are hydrated cross-linked polymeric systems that contain water in an equilibrium state, and may contain at least about 25%, or at least 35%, water in a hydrated state. Hydrogels are generally oxygen permeable and biocompatible, making them excellent materials for the production of contact lenses.

Conventional hydrogel contact lenses do not contain silicone-containing components and generally have higher water content, lower oxygen permeability, modulus, and shape memory than silicone hydrogels. Conventional hydrogels are made from a monomer mixture mainly containing hydrophilic monomers, such as 2-hydroxyethyl methacrylate ("HEMA"), N-vinylpyrrolidone ("NVP") ), or polyvinyl alcohol. U.S. Patent Nos. 4,495,313, 4,889,664, and 5,039,459 disclose the formation of conventional hydrogels. Conventional hydrogels may be ionic or nonionic, and include polymacon, etafilcon, nelfilcon, ocufilcon, lenefilcon, and the like. The oxygen permeability of these conventional hydrogel materials is generally lower than 20 to 30 barler.

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, and the like. "Silicone hydrogel" refers to a polymeric network made of at least one hydrophilic component and at least one silicone-containing component. The polysilicone hydrogel can have a modulus in the range of 60 to 200, 60 to 150, or 80 to 130 psi, and a water content in the range of 20 to 60%. Examples of silicone hydrogels include acquafilcon, asmofilcon, balafilcon, comfilcon, delefilcon, enfilcon, fanfilcon, forofilcon, galyfilcon, lotrafilcon, narafilcon, riofilcon, samfilcon, senofilcon, somofilcon, and stenfilcon, verofilcon (including all variations thereof) 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, 5,8 49,811, 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, 8,507,577, 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, No. 9,297,929 and the polysiloxane hydrogel prepared in WO 03/22321, WO 2008/061992, and US 2010/0048847. The entire contents of these patents are hereby incorporated by reference. Polysilicone hydrogel can have higher shape memory than conventional contact lenses.

Hydrogel lenses are viscoelastic materials. Optical distortion may occur in contact lenses if the lens interacts with the box or any air bubbles in the box. The degree of optical distortion and the length of time required for the distortion to relax will vary depending on the chemistry of the lens and, to a lesser extent, the geometry of the lens. Conventional lens materials (such as poly(hydroxyethyl methacrylate)-based lenses like etafilcon A or polymacon) have lower loss modulus and tan delta than polysilicone hydrogels, and can form lenses due to contact with packaging. Less and less severe optical distortion. Coatings of polysiloxane (which usually increases the elastic response of the body), wetting agents such as PVP (which usually increases the viscous reaction), or conventional hydrogel materials (which can reduce the elastic reaction at the lens interface) are combined with Injection can change the viscoelastic properties of the lens. It is known that hydrogel contact lenses, and polysilicone hydrogel contact lenses with short-acting or hard cross-linking agents and/or hardeners, have short-term shape memory and are less likely to deform during storage. As used herein, after accelerated aging at 55°C for 5 weeks, a high or relatively high shape memory hydrogel exhibits an optical distortion of at least about 0.18 due to contact with air bubbles or packaging boxes. Viscoelastic properties, including loss modulus and tan δ, can be measured using dynamic mechanical analysis.

Contact lenses can be of any geometry or power and have a generally hemispherical shape with a concave back side that rests against the eye during use and a convex front side that faces away from the eye and contacts the eyelids during blinking. .

The center or vertex of the lens is the center of the optical zone of the lens. The optical zone provides optical correction and may have a diameter of between about 7 mm and about 10 mm. The lens periphery or lens edge is the edge where the front and back sides meet.

Embodiments may include a lens support surrounded by a sealable cavity (also referred to interchangeably as a chamber). The cavity may have any convenient form, and may include a package base and at least one lid, each of which is described in detail below. As used herein, the phrases "the lid," "a lid," "the base," and "a base" include both the singular and the plural . The lid and package base are sealed to each other to form a cavity that maintains the sterility of the contact lens, support, and package solution during shipping and storage prior to use. Contact lens packaging boxes are made of materials that are compatible with contact lenses and solutions and are retortable and bio-inert.

"Film" or "multilayer film" is used to seal packaging boxes and is often called lidstock. Multilayer films used in conventional contact lens packages may be used in the packages of the present invention as components of the base, lid, or both. Multilayer films include a plurality of layers, including barrier layers (including foil layers, or coatings, sealing layers) that seal the film to the rest of the box, and may also include additional layers selected from Peeling off initial layers, laminated layers, and layers that improve other box properties (such as stiffness, temperature resistance, printability, puncture resistance, resistance to water or oxygen, and the like). Multiple layers of film create a steam-sterilizable (retortable) seal. Multilayer films may include PET, BON, or OPP film layers to increase stiffness and temperature resistance, or EVOH or PVDC coatings to improve resistance to oxygen or water vapor.

As used herein, "unopened state" or "unopened" refers to a contact lens package that is closed and contains the contact lens in solution.

As used herein, "opened state" or "opened" refers to the contact lens package after the sterilization seal has been broken. Depending on the context described herein, the open state extends to the state of the package when the user has manipulated the package to cause the lens to be lifted out of the package solution for transfer by the user.

As used herein, "wearer" or "user" refers to the person who opens the contact lens package. A user is generally a person who opens the package and simultaneously transfers the contact lens contained therein to his or her eye. However, in some scenarios, the user may be a person who handles the lens packaging on behalf of the wearer, such as an eye care provider ("ECP") or another person who demonstrates or assists the wearer.

The box solution is any physiologically compatible solution that is compatible with the selected lens material and packaging. The box solution includes a buffered solution with physiological pH, such as a buffered saline solution. The carton solution may contain known components, including buffers, pH and tension adjusters, lubricants, wetting agents, nutritional supplements, pharmaceuticals, carton inner coating components, and the like.

The packaging box base may form the bottom of the packaging box. They can be made from any material suitable for packaging medical devices, including plastic. The packaging base may be made from a polymer, rubber, or plastic selected from the group consisting of moldable and preferably injection molded polymers, rubbers, or plastics, and is chemically and physically compatible with the lenses, packaging solution, and any additives included therein. The properties are compatible with the sterilization requirements of contact lens manufacturing. Examples of suitable materials include polyolefins, including polypropylene, and olefin copolymers, including COP (cycloolefin polymers) and COC (cycloolefin copolymers), and blends thereof.

The package lid is typically placed over the upper portion of the package and sealed with the base to form a cavity containing at least a portion of the lens support, the lens, and the package solution. The cover may be made of any material suitable for packaging medical devices, including molded sheets of foil or plastic, laminated films, or plastic. Packaging boxes containing plastic for one structure and foil or laminate film for another structure, or packaging boxes containing foil or laminate film as outer layers of lid and base, are known in the art and are examples of suitable combinations .

References throughout this specification to injection molding procedures and the use of materials conventionally applied to injection molding should be understood as illustrative. One of ordinary skill in the art will appreciate that other means of manufacturing are possible within the scope of the appended claims, including, but not limited to, alternative molding procedures, thermoforming, 3D printing, and the like. Likewise, references to heat seal and heat sealing are illustrative of the embodiments described herein. Other means of fastening packaging components will be apparent to those of ordinary skill in the art, including the use of adhesives, glue, thermal bonding, welding (such as thermal welding, ultrasonic welding, or laser welding), or a Mechanical traps, and the like.

Certain aspects of the present invention may be used to reduce or prevent significant optical damage to contact lenses due to interactions with air bubbles or the interior of the lens packaging, which may occur due to gravity or other forces during storage or shipping ( such as mechanical pressure exerted from outside the packaging box). As used herein, significant optical damage means a root-mean-squared (RMS) value equal to or greater than about 0.08 µm.
