Definitions

  • This invention generally relates to improved contact lens containers and methods for their use.
  • the present invention pertains to contact lens containers prefilled with contact lens treatment solutions. More particularly, the invention relates to a ready-to-use recloseable and resealable contact lens container for holding contact lenses and contact lens treatment solutions that can be used to clean, disinfect, and rinse contact lenses either one time or several times before being discarded.
  • the present invention also relates to a contact lens pouch prefilled with a contact lens care solution, and more particularly relates to a resealable/disposable contact lens pouch prefilled with a contact lens care solution that is used to clean, store, disinfect and rinse a contact lens.
  • a sterile environment is required where the lens can be disinfected and/or stored.
  • This sterile environment usually means soaking the contact lens in a disinfecting or sterile solution. This is especially important in the care of soft contact lenses made of hydrophilic polymeric materials.
  • U.S. Patent No. 5,053,208 to Seamons, et al. discloses a contact lens disinfecting kit having an open-top lens container, an elongated piercer mounted in the lens container in an upright position such that the piercer divides the interior of the lens container into two separate contact lens receiving ports.
  • the Seamons, et al. device requires elaborate effort of piercing the compartment before using the container and moreover, it does not have a resealable top.
  • U.S. Patent No. 4,691 ,820 to Martinez discloses a molded blister package for storing and dispensing a hydrophilic contact lens having a base portion which includes a cavity surrounded by an outstanding flange and a sheet cover sealed to the flange to enclose the cavity.
  • the Martinez package is mainly used for shipping and dispensing contact lenses and is not amenable to reclosure once the package is opened and sterility lost.
  • Numerous other patents were issued on permanent contact lens containers, for instance, U.S. Patent No. 5,131 ,532 to Ives, U.S. Patent No.
  • a contact lens container prefilled with contact lens treatment solutions that can be used either once or several times by utilizing a recloseable and resealable top is provided.
  • a contact lens container prefilled with contact lens treatment solutions and constructed with a base member having at least one compartment, and more preferably two compartments, is provided with a laterally projected flange around the perimeter of the base member, a reusable adhesive is deposited on the projecting flange, and a cover sheet member extending at least across the full length and width of the compartments is releasably united to the base member at the flange by the adhesive and thus forming a fluid-tight seal.
  • the layer of adhesive is chosen such that it is capable of uniting the cover sheet member and the base member at the flange repeatedly after several uniting and releasing operations between the two members.
  • a container is provided with a sliding cover equipped with means to slidingly engage the laterally projecting flange on the base member and extending across the full length and width of the base member so that a fluid-tight seal between the base member and the sliding cover can be obtained when the cover is in a fully closed position.
  • a flexible cushion liner is used inside the cover member to provide a fluid-tight seal.
  • a contact lens pouch prefilled with a contact lens care solution is constructed with a resealable top equipped with a plastic inter-locking device.
  • the contact lens pouch may be prefilled at the factory with a contact lens care disinfection solution and then be marketed at a pharmaceutical outlet.
  • the contact lens wearer opens the resealable top to deposit a contact lens in the pouch for the cleaning, disinfecting and storing of the lens and then reseals the top. After a predetermined period of time necessary to disinfect the lens, the wearer opens the pouch again, removes and rinses the contact lens and places it in the eye. The pouch is then discarded.
  • the pouch is flexible and can be carried around by the wearer conveniently in a pocket or in a purse.
  • This preferred embodiment is most suitably used with an "all-in-one" type of contact lens care solution which accomplishes the functions of cleaning, disinfecting, storing, rinsing and lubricating a contact lens all by a single solution.
  • a contact lens pouch may be constructed with two compartments with a fluid-tight seal therein between.
  • a resealable top is provided such that the contact lens cleaning, disinfecting, and storing functions can be carried out by the wearer in the same way as that described in the preferred embodiment.
  • the second compartment which is juxtaposed to the first compartment, is equipped with a non-resealable, perforated tear-line at the top.
  • This second compartment contains a solution for rinsing and lubricating the contact lens.
  • a suitable solution is a saline solution.
  • This embodiment is more suitably used in an application where a solution for cleaning and disinfecting and a separate solution for rinsing and lubricating are used.
  • a pouch that has three separate compartments may be constructed.
  • Each of the first two compartments are equipped with a resealable top designed to store a left eye contact lens and a right eye contact lens, respectively.
  • the third compartment which contains a rinsing solution is equipped with a non-resealable tear-line at the top for opening. The rinsing solution in the third compartment can be used to rinse both the left eye contact lens and the right eye contact lens after the two lenses are cleaned and disinfected in the first and the second compartment, respectively.
  • the present invention is further directed to a method of using a contact lens pouch equipped with a resealable top and prefilled with a contact lens care solution to clean, disinfect, store, and rinse contact lenses.
  • the pouch is flexible and can be carried around by the contact lens wearer conveniently and can be used once and then be discarded.
  • FIG. 1 is a schematic showing the preferred embodiment wherein a cover sheet member is partially peeled back exposing the base member and the compartments.
  • FIG. 2 is a cross-sectional view taken along 2-2 in FIG. 1 showing the wrap-around arrangement of the cover sheet member at the rear flange of the base member.
  • FIG. 3 is a schematic showing a variation of the preferred embodiment in which only half of the cover sheet member for one compartment is peeled back.
  • FIG. 4 is a schematic showing the alternate embodiment in which a sliding cover is partially sealing the top of a base member.
  • FIG. 5 is a cross-sectional view taken along 5-5 in FIG. 4 showing the sliding cover member equipped with the slidingly engaging means and the flexible liner sealing means.
  • FIG. 6 is a schematic view of the preferred embodiment wherein the contact lens pouch is equipped with a resealable top.
  • FIG. 7 is an enlarged cross-sectional view of FIG. 6 taken along line A- A.
  • FIG. 8 is a schematic view of a first alternate embodiment wherein two compartments are provided.
  • FIG. 9 is a schematic view of a second alternate embodiment wherein three compartments are provided.
  • FIG. 1 wherein a schematic view of container 10 having a base member 14 and a partially peeled back cover sheet member 18 is shown.
  • the base member 14 has two compartments 20 and 22 and a partition 24 therein between.
  • a pair of contact lenses 12 are shown in the compartments.
  • Lens care solution either the same or different, are filled into compartments 20 and 22.
  • the base member 14 contains only one compartment and therefore filled with only one solution.
  • other alternatives to solution such as powders, pills, etc., may be suitably used in compartments 20 and 22.
  • the compartments 20 and 22 may be suitably marked left and right by molded-in symbols such that lenses for the left eye and for the right eye may be appropriately placed in each compartment without confusion.
  • the cover sheet member 18 extends at least across the full length and width of the two compartments 20 and 22 and covers the flange 26.
  • the laterally projecting flange 26 should have a suitable width such that adequate adhesion between the cover sheet member 18 and flange 26 may be obtained by the adhesive layer 28 deposited on flange 26. It should be noted that the adhesive layer 28 covers most of the flange area 26 around the perimeter of the compartments 20 and 22 including the center flange area 30.
  • FIG. 2 A cross-sectional view taken along section 2-2 in FIG. 1 is shown in FIG. 2. It should be noted that the cover sheet member 18 is wrapped around the rear flange 32 forming a rear edge wrap 34. This rear edge wrap 34 at the rear flange 32 prevents the user from accidentally peeling the cover sheet member 18 completely off the base member 14.
  • FIG. 3 shows a slight variation from the preferred embodiment in FIG. 1. It is seen that the cover sheet member 18 has a perforated line 36 along the center of the sheet member overlapping the center flange 30 of the base member 14.
  • the perforated line 36 facilitates the tearing of the cover sheet member 18 along the center such that one side of the cover sheet member 18 may be peeled back from the base member 14 independently of the other side. This enables the user to use a single compartment at a time without opening and possibly contaminating the other compartment.
  • the base member 14 which may alternately contain one, two, three or more compartments, can be suitably injection molded of plastic materials or thermoformed from extruded plastic sheets.
  • a suitable plastic material may be polypropylene, polyethylene, high density polyethylene, ultra high molecular weight polyethylene, polyamide, ABS, polystyrene, maleic anhydride modified polystyrene and polycarbonate.
  • the material should be capable of being sterilized at 120° C. without substantial loss (preferably not more than 20%) of its physical properties of dimensional stability, warpage, and shrinkage.
  • the plastic material should also have low water and vapor permeability to prevent the evaporation of the lens treatment solution.
  • the plastic material should not be permeable to bacteria in order to avoid contamination.
  • the cover sheet member 18 may be a film made of a plastic material that has small elongation upon stretching, or a metal foil that has a plastic coating on the side facing the solution, or a laminated metal foil/plastic film.
  • the elastic material or the metal foil should have chemical resistance to those chemicals that are normally found in lens care solutions.
  • the adhesive layer 28 used on flange 26 should be selected such that it is capable of providing a fluid-tight seal between cover sheet member 18 and base member 14, and furthermore, of providing a fluid-tight seal after repeated uniting and releasing between the two members. This is to ensure that the cover sheet member 18 after being peeled off can be reclosed and resealed on top of the base member 14 such that lens container 10 may be used several times before it is discarded.
  • a suitable adhesive for this purpose may be a pressure-sensitive type adhesive such as those of pol ⁇ butadiene, polyisoprene, natural rubber, nitrile rubber, epoxy-n ⁇ lon, nitrile- phenolic, neoprene-phenolic, and vinyl-phenolic.
  • Other closure means not using adhesives such as a zip-lock type of arrangement may also be used so long as a fluid-tight seal can be obtained.
  • a suitable thickness for the adhesive layer may be any thickness between about 0.0001 inches to about 0.125 inches.
  • a method of using a container for holding contact lenses and contact lens treatment solutions can be carried out by first providing a base member 14 having at least two compartments 20 and 22 each having a predetermined length and width situated next to each other with a partition 24 therein between and a laterally projecting flange 26 and 30 around the perimeter of the compartments. A layer of suitable adhesive having a sufficient thickness is then deposited on flange 26 and 30. The compartments are then filled with at least one contact lens treatment solution such that one solution is filled into each compartment. The cover sheet member 18 is then united to the base member 14 by the adhesive layer 28 forming a fluid-tight seal.
  • FIG. 4 shows one of the alternate embodiments of the present invention in which a sliding cover member 40 is utilized to provide a fluid-tight seal on base member 14.
  • a cross-sectional view taken along section 5-5 in FIG. 4 is shown in FIG. 5.
  • sliding cover member 40 is equipped with a stop 44 at the rear edge 42. This is shown in the break-away view in FIG. 4.
  • the stop 44 provides a convenient guide in closing the sliding cover member 40 on the base member 14 along flange 26 such that it can not accidentally slide off base member 14.
  • the sliding cover member 40 is equipped with sliding engagement means 46 and 48 at each end of the cover member which provides a spring closure action on flange 26 of the base member 14 so that cover member 40 is pressed tightly against flange 26 providing a fluid-tight seal.
  • a flexible cushion liner 50 is used inside the sliding cover member 40 to facilitate the fluid-tight seal.
  • This flexible cushion liner can suitably be made of an elastomeric material such as neoprene rubber, nitrile rubber, urethane rubber, etc., a foam material such as polyurethane foam, polyester foam, neoprene foam, etc., or any other flexible and pliable sheeting material. It should have adequate chemical resistance to chemicals that are normally found in lens treatment solutions for cleaning, disinfecting, rinsing, and wetting contact lenses.
  • the sliding cover member 40 may be suitably molded of a plastic material such as those used for base member 14.
  • FIG. 4 shows that sliding cover member 40 is slid off half way on base member 10 such that half of the opening for compartments 20 and 22 are exposed. It is possible to mark the two compartments each as left and right to facilitate the use for the left eye lens and the right eye lens.
  • sliding cover member 40 described in the alternate embodiment is only one of the preferred means for achieving a fluid- tight seal on the base member 14.
  • Other types of closure means including, but not limited to, a press-on lid should also function satisfactorily.
  • a plurality of lens containers may be packaged together in strips in which the containers are connected to each other along the sides that can be easily separated.
