Description
    FIELD OF THE INVENTION
  • [0001]
    The present invention relates to a contact lens package and, more particularly, to a contact lens package adapted for improved accessibility to the contents thereof and for retail display.
  • BACKGROUND OF THE INVENTION
  • [0002]
    Contact lenses, particularly disposable contact lenses, have been conventionally packaged in “blister packs.” In general, a blister pack comprises a rigid plastic (e.g., polypropylene), concave-shaped receptacle for receiving a contact lens and a flexible cover, typically made from a laminate material (such as metal foil), which is removably attached to the receptacle for enclosing the lens therein. Within each blister pack are a single contact lens and a sufficient amount of contact lens solution to prevent drying of the contact lens and to maintain the contact lens readily available for use.
  • [0003]
    Conventional blister packs are also not adapted to be displayed on conventional display units, such as peg-hook-type or wire-hook-type displays. Likewise, a blister pack for a single contact lens is not adequate to be displayed on retail shelves. Accordingly, there is a need for a contact lens package that is adapted for display on conventional display units.

  • DETAILED DESCRIPTION OF THE INVENTIONS
  • [0011]
    The invention includes a contact lens package, comprising, consisting essentially of, or consisting of a first shell member having a first end and a second end; a second shell member having a first end and a second end, said first and second shell members being removably attached to each other such that said first ends of said first and second shell members are juxtaposed with one another and said second ends of said first and second shell members are juxtaposed with one another, said first ends of said first and second shell members forming a gusset that is sized and shaped for enabling the package to be situated in a standing position; and a receptacle interposed between said first and second shell members, said receptacle being adapted to receive and house a contact lens and an amount of contact lens solution.
  • [0012]
    Further the invention includes a contact lens package, comprising a first shell member having a first end and a second end opposite said first end thereof; a second shell member having a first end and a second end, said first and second shell members being removably attached to each other, said first ends of said first and second shell members being juxtaposed with one another and said second ends of said first and second shell members being juxtaposed with one another; a hanging-means for hanging the package from a display rack; and a receptacle interposed between said first and second shell members, said receptacle being adapted to receive and house a contact lens and an amount of contact lens solution.
  • [0013]
    The present invention overcomes the disadvantages and shortcomings of the prior art discussed above by providing a new and improved contact lens package which includes first and second shell members removably attached to each other. Each of such shell members have a first end and a second end. Each such first and second end of a single shell member are preferably in opposite positions on the shell member, but can be located in other positions on that shell member. In one embodiment the first ends of the first and second shell members form a gusset that is sized and shaped for positioning the package in a free standing position, such as on display shelf. One of the shell members (for instance, the second shell member) contains a window that visually exposes the contact lens to enable a user to visually inspect the contact lens (e.g., for damage) before opening the package. Preferably a sponge member that holds solution is interposed between the first and second shell members for housing a contact lens. The sponge member holds an amount of the contact lens solution sufficient to keep the contact lens saturated, thereby allowing the contact lens to retain its intended shape and softness. The amount of solution is between about 500 μL and about 1,500 μL, more preferably between about 900 μL to about 1,000 μL. The preferred contact lens solution is saline solution or packaging solution, but other solution are contemplated by this invention including solutions containing ocular medicaments. Preferably the sponge member includes a recess for housing the contact lens.
  • [0014]
    In accordance with another aspect of the present invention, one end of each of the first and second shell members, opposite the end of the gusset, contains a pull tab, the tabs being juxtaposed with one another when the first and second shell members are attached to each other. The package is opened by pulling apart the juxtaposed tabs and separating the first and second shell members from each other, thereby allowing access to the contact lens. A plurality of bumps protrudes from an exposed surface of each of the tabs, the bumps being sized, shaped and positioned to enable a user to better grip the tabs when pulling them apart. The tabs have aligned apertures for hanging the package on a peg hook or a wire hook of a retail display rack.
  • [0015]
    Specifically, the present invention has been adapted for use in housing a single contact lens and an amount of contact lens solution. However, the present invention can be utilized to house a plurality of contact lenses and an amount of contact lens solution therefor. Further features and advantages of the invention will appear more clearly on a reading of the detailed description of an exemplary embodiment of the invention, which is given below by way of example only with reference to the accompanying drawings.

The bumps 40, 46 allow the user to attain a better grip when separating the tabs 22, 26. Next, the user simultaneously pulls each of the tabs 22, 26 and peels apart the shell members 12, 14, thus breaking the seals between the bands 50, 52 and the grooves 56, 58 and the seal between the flanges 30, 34. The seals between the bands 50, 52 and the grooves 56, 58 prevent inadvertent opening of the package 10. It is noteworthy that the shell members 12, 14 are sufficiently flexible to enable a user to easily peel them apart from one another. It is also noteworthy that the strength of the seal between the shell members 12, 14 is weak enough to allow a user to easily peel them apart from one another, but strong enough for the package 10 to retain a liquid-tight seal so as to prevent any evaporation of the contact lens solution therefrom or any contamination of the contact lens 76 and the contact lens solution from foreign materials. When the aforesaid seals are broken and the shell members 12, 14 are separated, the contact lens 76 is exposed and made accessible to the user. It is noted that the window 36 enables a user to view and inspect the contact lens 76 (e.g., for damage) before opening the package 10.
  • [0026]
    Referring to FIG. 5, the gusset 66 enables the package 10 to remain in a free standing position, for instance, in a vertical position on a horizontal flat surface 78 (e.g., a retail display shelf). Referring to FIG. 6, the holes 38, 44 enable the package 10 to hang from a wire-hook-type display rack 80 or a peg-hook type display rack (not shown in the Figures). Alternatively, the package 10 need not include the holes 38, 44 and other known hanging means, such as a hook member, may be utilized in their stead (not shown in the Figures).
