1. Field of the Invention

The field of invention relates to contact lens storage apparatus, and more particularly pertains to a new and improved contact lens date storage container wherein the same permits the visible notation of time passage for counting days worn of disposable contact lenses.

2. Description of the Prior Art

Contact lenses, and particularly disposable contact lenses, are worn for a predetermined period of days and then disposed. To provide for date notation and time passage relative to the contact lenses, the instant invention attempts to overcome deficiencies of the prior art by providing for a storage container having a rotary dial to provide for visual indication of time passage. Prior art contact lens cases such as indicated in U.S. Pat. Nos. 4,826,001; 4,838,413; 4,909,382; and 4,925,017 are examples of prior art contact lens storage containers wherein the same do not provide for the convenience and ease of use of the construction of the instant invention providing for the visual indication of time passage relative to a contact lens wearing event and in this respect, the present invention substantially fulfills this need.

In view of the foregoing disadvantages inherent in the known types of contact lens storage apparatus now present in the prior art, the present invention provides a contact lens date storage container wherein the same utilizes a rotary dial to indicate time passage relative to insertion of disposable contact lenses relative to an individual's eyes. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved contact lens date storage container which has all the advantages of the prior art contact lens storage apparatus and none of the disadvantages.

To attain this, the present invention provides a storage container including a base housing having first and second containers mounted to the housing. The base housing includes a cavity therewithin, having a rotatable dial projecting through a first side wall of the housing. The dial includes sequential digits visible through a window in a top wall of the housing, wherein sequential days are counted relative to contact lenses, and particularly disposable contact lenses stored within the first and second containers.

My invention resides not in any one of these features per se, but rather in the particular combination of all of them herein disclosed and claimed and it is distinguished from the prior art in this particular combination of all of its structures for the functions specified.

There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated.

With reference now to the drawings, and in particular to FIGS. 1 to 11 thereof, a new and improved contact lens date storage container embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

More specifically, the contact lens date storage container 10 of the instant invention essentially comprises a base housing 11 mounting a first container 13 and a second container 14 in a spaced parallel relationship relative to one another orthogonally to a housing top wall 12 of the housing 11. The first container 13 is mounted to a first end of the top wall 12, with the second container mounted to a second end of the top wall 12. A first lid 15 and a second lid 16 are respectively secured to upper ends of the first and second containers 13 and 14 to provide for reception of storage of contact lenses therewithin the first and second containers in a conventional manner. The base housing further includes a base housing floor 17 (see FIG. 3 for example) defining a housing cavity between the housing floor 17 and the top wall 12. A housing first slot 18 is directed through a first of the side walls of the housing 11 intermediate the first and second containers 13 and 14. A rotary dial 19 rotatably mounted about a dial axle within the cavity of the housing includes an annular edge 20, with spaced notches 21 spaced at equal predetermined intervals within the annular edge 20. The structure of the FIG. 3 indicates spaced resilient lugs 22 mounting a U-shaped spring plate 23, with the U-shaped spring plate arranged for reception within one of the notches 21 to maintain the dial in a predetermined angular orientation relative to the slot to project a digit imparted upon a top surface of the dial through a top wall window 25 (see FIG. 1) for viewing. In this manner, sequential days for use of contact lenses are indicated. While twelve days are indicated in association with twelve notches, it should be understood that any desired interval period may be indicated by utilizing an equal number of digits and notches, in a manner as illustrated in FIG. 3. The first and second containers 13 and 14 include umbrella supports 24 for positioning a contact lens thereon. The umbrella supports are formed of a semi-spherical configuration of semi-annular ribs.

The organization 10a, as indicated in FIGS. 5-11, indicates a modified aspect of the invention, wherein a signal rod 26 having a flag 27 mounted at a first end thereof is mounted to a spring hinge 28 at a second end of the rod 26 to maintain the rod in a second position, as indicated in FIG. 5, orthogonally oriented relative to the housing top wall 12 from a first position parallel to the top wall 12, as indicated in FIG. 5. A second slot 29 is directed through a second side wall of the housing 11, having a latch plate 30 projecting through the slot for overlying the signal rod 26. Reference to FIG. 7 indicates the operation of the organization, as indicated in the FIG. 5, wherein the latch plate 30 is mounted to a distal end of a latch plate spring plate 32 that is secured about a support post 33. An abutment tank 34 is mounted to an upper edge of the spring plate 32, wherein an abutment finger 35 mounted to the top surface of the rotary dial 19 intermediate the first and last enumerated notches 21 abuts the abutment tang 34 to displace the latch plate 30 from the signal rod 26 to permit the signal rod 26 to pivot to the second position, as indicated in FIG. 6. As the abutment tang 34 and the associated spring plate 32 displace, they will rotate sufficient to permit the abutment finger 35 to pass over the abutment tang 34 permitting the spring plate 32 to twist back to its original configuration, as indicated in FIG. 7a and FIG. 7. As illustrated, the abutment finger 35 will pass over the support post 33 and the spring plate 32 to engage the abutment tang 34. Upon this event, the passage of the last day of the sequence, as indicated by the rotary dial, provides for pivoting of the signal rod to the second position for further visual indication of the passage of the predetermined elapsed number of days available to an individual wearing disposable contact lenses to further indicate to that individual to dispose of such lenses and employ a further set.

The FIGS. 8-11 indicates the first container 13 having first container ferrous plugs 36, with the second container having second container ferrous plugs 37, each mounted to upper ends of each container. The first plugs 36 are of a first predetermined number, with the second plugs of a second predetermined number unequal to the first predetermined number. A modified first cap 15a includes first cap magnets 38, with each of the first cap magnets aligned with one of the first ferrous plugs 36 and one of the second cap magnets 39 equal to the second predetermined number aligned with one of the second ferrous plugs 37. In this manner, only the proper cap positioned upon the proper container will permit alignment of the first container ferrous plugs 36 to the first cap magnets 38 and similarly, the second ferrous plugs 37 aligned with the second cap magnets 39.

As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
