Primary Examiner-Leonard Summer [5 7] STRACT A case for storing soft contact lenses, usually in a liquid which cleans and sterilizes the stored lenses, comprising a container having a threaded, fluid-tight closure cap, a base plate on the cap insertable in the container as the cap is placed on the container, and two upwardly opening compartments in the base plate for receiving two lenses, each compartment containing a perforated hemispherical lens support that is mounted in the compartment for movement between a lowered, retracted position and a raised, extended position. A hinged cap covers each compartment and is releasably latched in a closed position over the lens support, which is movable to the raised position by means of a push button extending through the underside of the base. A lost-motion connection limits the back and forth motion of each lens support, and the cover cups are held in spaced relation with the base and with the lens supports, when closed, to prevent damage to lenses on the supports.

12 Claims, 7 Drawing Figures SOFT CONTACT LENS CASE BACKGROUND OF THE INVENTION This invention relates to a case for storing contact lenses, and more particularly to a storage case that is specially designed to hold plastic hydrophilic contact lenses, popularly referred to as soft lenses.

Many different types of cases have been available for the storage of hard contact lenses, and typically have provided two covered pockets or recesses in which two lenses can be stored. In some instances, there has been a common cover for the two pockets, and in others, the pockets have had individual covers.

One conventional storage case shown in US. Pat. No. 3,025,950 has two compartments that are formed by recesses spaced apart along an elongated plate, and two covers that are connected to the plate by hinge straps permitting the covers to swing between open and closed positions and to be latched against the plate in the closed positions. The plate is insertable in a cupshaped container, and is carried by a base for closing the open end of the container.

This general approach is well suited for use with soft contact lenses, which should be stored in cleaning or sterilizing liquid that can be held in the container. One of the problems with soft lenses, however, is their susceptibility to damage. There is a danger of inadvertent pinching of the lenses by the covers, of the compartments as the latter are closed, and also a danger of damage during removal of the lenses from the compartments. Moreover, such removal can be difficult because of the slippery and difficult to grip nature of soft lenses.

Another special problem with soft lenses is their characteristic property of absorbing relatively large amounts of the soaking or sterilizing solution, and the resulting tendency to concentrate compounds from the solution. If the solution tends to dissolve coloring matter from the case, or the material of the case itself, these substances can be concentrated in quantities 'by the lenses, even though the concentration in the solution may be non-toxic.

SUMMARY OF THE INVENTION The present invention provides a lens storage case that avoids the foregoing problems by storing the lenses in covered compartments which eliminate the danger of pinching of the lenses, make it possible to grasp each lens quickly and easily for removal from its compartment, and is composed of material which is nondiscoloring and non-toxic, even after prolonged exposure to cleaning and sterilizing fluid.

For these purposes, the storage case of the invention, as illustrated in the preferred embodiment shown herein, comprises a container with a fluid-tight closure, and a base in the formof a plate that is insertable in the closure and has two recesses that normally are closed by hinged covers, and in which two lens supports are mounted for limited movement relative to the base plate between lowered, retracted positions and raised, extended positions. Each lens support is shaped to hold a lens in a retracted position inside the recess when the support is retracted, and to shift the lens out of the compartment into an easily accessible position when the support is extended, and is movable to the extended position by means accessible from outside the compartment.

When closed, the covers are spaced from the lens supports far enough to prevent damaging contact between the covers and the lenses even if a support should be extended inadvertently while the cover is closed, and are mounted on and latched to the base in a manner which leaves an annular gap between the cover and the base. This gap prevents pinching of a lens that might slip into a position between the edge of the cover and the base.

More specifically, the lens supports are formed with hemispherical supporting surfaces which support the lens in a substantially physical stress-free condition; a lens may be easily removed therefrom when a support is extended. The supports are mounted with close sliding fits in holes of circular cross-section in the base plate and retained in the holes by a lost-motion connection which determines the raised and lowered positions. A pin extends downwardly through the base plate from each support and is exposed on the lower side thereof to serve as a push-button actuator for each support.

Extending around the periphery of each support is an annular reatining groove that is bounded by an upstanding annular lip for preventing lenses from slipping off the support. The supports are perforated to cooperate with the cover gaps in providing a high degree of circulation of liquid through the compartment for proper sterilization and to facilitate cleaning and act to prevent the lenses from possibly adherring to the upper surfaces of the supports due to surface tension.

Suitable non-toxic, non-discoloring materials for the case are olefin polymers such as high-density polyethylene and polypropylene. A seal ring preferably is provided between the container and the closure, and also should be composed of non-toxic, non-discoloring material. Suitable materials for sealing rings include neoprene elastomers (polymers of 2-chlorobutadiene-l ,3 certain silicones and teflon, although other materials also may be used.

Other aspects and advantages of the invention will become apparentfrom the following detailed description, taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION As shown in the drawings for purposes of illustration, the invention is embodied in a case for holding a pair of contact lenses when the lenses are not in use, and for soaking the lenses in a cleaning or sterilizing solution as an incident to such storage. In general, the case comprises a container 14 having an open end 16, a cap 18 for closing and sealing the open end, and a lens-supporting base plate 20 mounted on the cap for insertion in and removal from the container as an incident to the closing and opening of the container.

In this instance, the container 14 has an internally threaded neck 22 defining the open end 16, and the cap 18 has an externally threaded, generally cylindrical plug 24 which fits snugly into the neck 22, and a knurled head 26 with which the cap is gripped and held. An O-ring 28 is carried in a groove around the plug to provide a fluid-tight seal between the plug 24 and the neck 22.

The base plate 20 is joined at one end to the inner end of the plug 24 and projects into the container from the plug when the latter is in the neck. The plate is generally parallel to the axis of the plug, and is offset somewhat to one side of this axis, downwardly as viewed in the drawings.

To support a contact lens 12 on the base plate, the latter has two longitudinally spaced compartments 30 and 31, each comprising a recess 32 in the base plate, a cover 34 overlying the upper side of the recess and movable relative thereto between open and closed positions, and a lens support 36 in the recess for holding a lens therein. Each of the covers is an inverted, preferably hemispherical cup which is joined to the top of the base plate along one side thereof by a hinge, and has a latch on the opposite side for holding the cover releasably in a closed position over the associated recess.

In accordance with a primary aspect of the present invention, each lens support 36 is shaped and mounted to hold a lens 12 in a protected and secure position within the compartments 30, 31, and at the same time, to facilitate the removal of a lens from one of the compartments in a quick and easy manner. For these purposes, each support is movable in the associated recess between a lowered, retracted position in which the lens 12 is held well below the cover 34, and a raised, extended position in which the lens is held well above the top of the base plate so as to be easily removed from the support when the cover is open. A lost-motion connection between the base and the lens support permits limited lowering and raising motion while retaining the support in the recess, and the support is moved by means of a pin 38 which projects through the base plate 20 and is accessible from the underside thereof.

As shown most clearly in FIGS. 2 through 7 the recesses 32 herein are circular in cross-section and extend completely through the base plate 20, and the lens supports 36 are inverted cups that are fitted in the recesses with close sliding fits. The supports have convex hemispherical upper surfaces 40 for receiving and holding the lenses 12, in the manner shown in FIGS. 2 through 4, preferably are perforated in the areas beneath the lenses, for liquid circulation and to avoid any chance of sealing of a lens to the support, and have upturned annular lips 42 around the periphery of the surfaces 40 defining grooves for catching and holding a lens that might slip off the central area.

A pair of laterally spaced, longitudinal bars 44 are secured to the underside of the base plate to extend across the open sides of the lower sides of the recesses. These bars form stops for limiting downward motion of the supports, and thus determine the retracted positrons.

Extending downwardly along the wall of the recess 32 from the underside of the lower peripheral edge of each support are plurality of fingers 46, herein two, which have outwardly turned tabs 48 on their lower ends. These tabs are spaced from the underside of the base plate when the support is in the retracted position, as shown in FIG. 4, and engage the underside as the support is raised, as shown in FIG. 2. Thus, the fingers and the bars form the lost-motion connection between each support 36 and the base plate 20.

The pin 38 of each lens support 36 is joined to the underside of the latter at the center, and projects downwardly therefrom a distance substantially greater than the radius of the support, to project well below the base plate 20 and the bars 44 when the support is in the retracted position. To stabilize the lens support, the pin is non-circular in cross-section and is guided for upand-down sliding in a non-circular hole 50 in a washer 52 that extend between and is secured to the two bars 44. The pin 38 is preferably hollow to provide for improved communication of lens fluid to the lens.

For economical manufacture, each lens support may be made of suitable plastic as a one-piece molding including the hemispherical cup, the fingers 46 and the hollow pin 38; the plug 24, the base plate 20, the covers 34 and the bars 44 and the washers 52 also may be molded in one piece. Assembly of the lens supports 36 into the recesses 32 is accomplished simply by fitting each support into the top of the recess, aligning the pin 38 with the guide hole 50, and pressing the support downwardly into place. The lower ends of the fingers 48 are rounded so as to be deflected inwardly during assembly, and to snap resiliently outwardly after passing the bottom of the base plate.

Another feature of the present invention is the manner of mounting the covers 34 on the base plate for movement between the open and closed positions to minimize the danger of pinching the edge of a lens that accidentally slips into the area beneath the lower edge 35 of the cover, despite the presence of the retaining lip 42. To this end, the edge 35 of each cover is spaced above the top of the base plate when the cover is closed, and both the hinge and the latch are positioned as far as is practical from the edge of the support.

More specifically, the hinge comprises two integral straps 54 that are spaced apart longitudinally of the base and thickened on the undersides (when the cover is closed) to form pads that are offset downwardly from the edge of the cover. These pads engage the base plate while the edge is spaced from the base plate.

Similarly, the latch is formed by two integral hooks on the side of the cover opposite the hinge, and each hook comprises a pad 56 that is disposed below the edge 35, as shown most clearly in FIGS. 2, 3 and 5, and a resilient latch finger that is downwardly and inwardly inclined from the free end of the pad. As the cover is closed, the latch fingers engage the top of the base plate adjacent two semi-circular notices 58 in the edge of the plate, and yield to pass over the edge and into the notches. Then, after the ends of the fingers clear two thin ribs extending across the tops of the notches, they snap back to their normal condition in interlocked relation with the ribs.

Since both the hinge straps and the latch hooks are spaced apart longitudinally of the base plate, and their engagement with the base plate is limited to the area of the pads 54, and 56, the possibility of pinching a lens between the cover andthe base plate is limited. This factor, combined with the retaining lip 42 on each lens support, makes it highly unlikely that a displaced lens could be damaged by pinching.

To prevent discoloration or other injury to the lens as well as to prevent the lens from harming the eye of the wearer, it is important that the lens case be made from materials which will not release toxic materials which could concentrate in the lens. We have found that the contact lens cases made from olefin polymers such as high density polyethylene, e. g., Marlex available from Phillips Petroleum Co. are satisfactory. The preferred embodiment employs a sealing ring to insure a fluid-tight seal. It has been found that the selection of sealing rings must be carefully made because of their tendency to discolor the lens and also render the lens toxic to the eye of the user. For example, we have found that sealing rings made from certain medical grade Buna and silicone rubbers both cause corneal damage and conjunctival irritation to the eyes of test rabbits and that a sealing ring made from Buna-N rubber stains the soft lenses. We also have found that sealing rings made from neoprene elastomers (polymers of 2-chlorobutadiene-l,3) and teflon are non-discoloring and non-toxic. Additionally, sealing rings made of Buna-N rubber previously extracted from chloroform have been found to be non-staining and non-toxic. Other materials may also be used.

Further additions and modifications for convenience include adapting a portion of the outside surface of container 14 to hold a mirror 60 to facilitate insertion of the contact lens into the eye of the wearer. The visible portions of covers 34 also may be provided with marking indicia R and L for distinguishing between right and left lenses; color indicia also may be used.

The foregoing contact lens carrying case provides a convenient pocket size means for storing contact lenses and especially soft contact lenses in such a manner as to allow them to be cleaned and sterilized while being safely stored in covered compartments which eliminate the danger of pinching of the lenses. Features provided by the carrying case make it possible to grasp each lens quickly and easily for removal from its compartment. Finally, the carrying case may be composed of material which is non-discoloring and non-toxic, even after prolonged exposure to cleaning and sterilizing fluid.

While one form of the invention has been shown, it is apparent that changes therein will readily suggest themselves to those skilled in the art without departure from the spirit and scope of the present invention.
