Accordingly, those who work in the art will recognize that many modifications and adaptations to the present invention are possible and can even be desirable in certain circumstances and are a part of the present invention. Thus, the following description is provided as illustrative of the principles of the present invention and not in limitation thereof.

[0018] FIGS. 1-4 show an example of a dispenser 10 in accordance with one aspect of the current disclosure. The dispenser 10 is configured to house and dispense medication 12 from a squeezable eyedropper bottle 14 (see FIG. 5) into the eye 16 of a user 18 (see FIG. 3). In one aspect of the disclosure the squeezable eyedropper bottle 14 comprises a vial 20. In particular, in one aspect of the disclosure the squeezable eyedropper bottle 20 comprises a flattened base section 22, a flexible bulbous storage portion 24 and a dispensing nozzle 26 (see FIG. 5). In one aspect of the disclosure the medication 12 may comprise preservative-free ophthalmic medication. In other aspects, a wide range of squeezable eyedropper bottles 14 and medications 12 are contemplated. The dispenser 10, in one aspect, includes a first arm 28. The first arm 28 defines a first pivot end 30, a first dispensing end 32, a first exterior surface 34 and a first interior surface 36. In one aspect the dispenser 10, the first arm 28 and the remaining disclosure features are formed using 3D printing. In another aspect, the dispenser 10, the first arm 28, and the remaining disclosure features are formed using injection molding. In still another aspect, the dispenser 10 may be formed using known manufacturing techniques.

[0019] The dispenser 10 may further include a retention feature 38 positioned on the first arm 28. The retention feature 38 is configured to removably engage one of the squeezable eyedropper bottles 14 (FIG. 1-3). The retention feature 38 securely holds the squeezable eyedropper bottle 14 in a position parallel to the first arm 28. In one aspect the retention feature 38 may comprise a projection 40 from the first interior surface 36. In one aspect, the retention feature 38 may be molded as a unitary feature with the first arm 28. In another aspect, the retention feature 38 may be mounted to the first arm 28. As shown in FIG. 3, the retention feature 38 may further include a tapered slot 42 formed within the projection 40. In one exemplary aspect, the tapered slot 42 may be configured to frictionally engage the flattened base section 22 of the squeezable eyedropper bottle 14. This allows the squeezable eyedropper bottle 14 to be retained in the tapered slot 42 during operation of the dispenser 10 (see FIG. 4).

[0020] The dispenser 10 may also include a second arm 44 which defines a second pivot end 46, a second dispensing end 48, a second exterior surface 50 and a second interior surface 52. The second pivot end 46 is coupled to the first pivot end 30 of the first arm 28 so that the first interior surface 36 is movable relative to the second interior surface 52 of the second arm 44. In one aspect of the disclosure, the movement of the first interior surface 36 is movable relative to the second interior surface 52 may be achieved through a pivot hinge. In another aspect of the disclosure, the movement of the first interior surface 36 is movable relative to the second interior surface 52 may be achieved through a living hinge. In still another aspect of the disclosure, the movement of the first interior surface 36 is movable relative to the second interior surface 52 may be achieved through a fixed joint and accomplished through the flexibility of either the first arm 28, the second arm 44 or both. For example, the first arm 28 and/or the second arm 44 can resiliently deflect to effect movement of the first interior surface 36 toward the second interior surface 52 The second arm 44 is configured to squeeze the squeezable eyedropper bottle 14 as the second interior surface 52 is manually moved toward the first interior surface 36. In this fashion, the squeezable eyedropper bottle 14, and in one particular aspect the flexible bulbous section 24 is compressed and the medication 12 is forced out through the dispensing nozzle 26 (see FIGS. 3 and 5).

[0021] Although it is contemplated that the second arm 44 may be configured to squeeze the squeezable eyedropper bottle 14 as the second interior surface 52 is manually moved toward the first interior surface 36, in one particular aspect of the disclosure the dispenser 10 includes a pressure protrusion 54 extending from the second interior surface 52 (see FIG. 1). The pressure protrusion 54 is sized such that connection and pressure to the flexible bulbous section 24 is achieved prior to the second interior surface 52 making contact with any portion of the first interior surface 36 or the retention feature 38. In one particular aspect, the pressure protrusion 54 comprises an arched arm 56 protruding from the second interior surface 52. The arched arm 56 allows for sufficient strength to compress the flexible bulbous section 24 while allowing the size and weight of the dispenser 10 to be minimized.

[0022] The dispenser 10, in another aspect, may include at least one forehead/eyelid engagement arm 58 (see FIG. 1). The forehead/eyelid engagement arm 58 allows the user of the dispenser 10 to properly position the dispenser 10 over their eye 16 while accommodating instability in hand movements (see FIG. 3). In addition, the stabilization provided by the forehead/eyelid engagement arm 58 allows for both hands to operate the moving of the second arm 44 toward the first arm 28 for users that do not have the strength for single hand operation. The forehead/eyelid engagement arm 58, in one aspect, may include a curved forehead/eyelid engagement surface 60 that provides a comfortable and non-invasive contact with the user's forehead/eyelid. In one aspect, the forehead/eyelid engagement arm 58 engages the forehead to insure stability during dispensing of the medication 12. In another aspect, the forehead/eyelid engagement arm 58 engages the eyelid of the subject to both provide stability as well as prevent unwanted blinking during application. In still another aspect of the disclosure, the forehead/eyelid engagement arm 58 may comprise a plurality of forehead/eyelid engagement arms 58 (see FIG. 2). In this aspect, the duality of the engagement arms 58 may provide additional stabilization or a combination of stabilization and eyelid blinking prevention. Although a variety of positions are contemplated for the forehead/eyelid engagement arm 58 relative to the first arm 28, in at least one aspect of the disclosure the forehead/eyelid engagement arm 58 is angled between 20 and 45 degrees from the first arm 28. The angle of the forehead/eyelid engagement arm 58 to the first arm 28 helps improve medication application direction relative to the user's placement of the engagement arm 58. In this fashion, a user may find a physical feature on their forehead (such as an eyebrow) and have the security that the medication 12 will be properly applied.

[0023] Referring now to FIGS. 8 and 9, the dispenser 10 may further include a latch element 62 mounted or formed into the retention feature 38. The latch element 62, in one aspect, comprises a flexible cover over the tapered slot 42 that additionally secures the squeezable eyedropper bottle 14 within the retention feature 38. The latch element 62 allows the retention feature 38 to accommodate a wider range of squeezable eyedropper bottles 14 from different manufacturers or of different sizes while still allowing the user to securely bring the medication 12 to their eye 16. In another aspect, the latch element 62 may comprise a clip 64 (see FIG. 9) that provides additional security to the squeezable eyedropper bottle 14 while the user raises it to their eye 16.

[0024] In one additional aspect of the disclosure, the dispenser 10 may include a plurality of stiffening elements 66 formed or mounted on the first arm 28 and/or the second arm 44. The stiffening elements 66 on the first arm 28 allow the first arm 28, retaining the squeezable eyedropper bottle 14 to remain in a stable position. The stiffening elements 66 mounted on the second arm 44 allow the second arm 44 to flex in such a way that the pressure protrusion 54 properly engages the flexible bulbous section 24. This allows a single molded or printed dispenser 10 to provide all the characteristics described in the present disclosure.
