Definitions
- the present invention relates to devices for storing contact lenses.
- the first drawback is that the interiors of the receiving cups are completely smooth permitting the contact lenses to adhere to the sidewalls. Furthermore, due to the flat interior base, the contact lenses can also adhere to the bottom of the receiving cups.
- the prior invention claims a leak proof seal using a rubber ring.
- the drawback to this is, over time the rubber flattens and the seal is weakened causing the solution to leak out of the embodiment.
- the flattened rubber ring in combination with the poor alignment, makes the prior invention incapable of guaranteeing a leak proof device.
- the hinge area is weak in design due to an extreme concave area on the coverlids.
- the concave extends to the edges of the coverlids making the hinge attachment considerably thin. This creates a greater possibility of damage to the hinge area with repeated use.
- the present invention provides a means of storage for contact lenses in a secured environment. Additionally, it is an object of the invention to provide a means of storage for contact lenses that is durable and leak proof. It is another object of the present invention to provide a housing with an ergonomic design for comfort when opening and closing the embodiment. It is yet another object of the present invention to provide an adhere-free interior for ease of removal, and prevention of damage to contact lenses.
- the contact lens case incorporates ridges on the interior sidewalls of the receiving cups. This prevents the contact lenses from adhering to the sidewalls. The ridges also make it easier to remove the contact lenses and prevent damage thereof.
- the contact lens case further incorporates a convex interior base; this shape prevents the contact lenses from adhering to the base. Due to the shape of the lenses and the convex interior base, the contact point is significantly reduced.
- the convex interior base makes it easier to remove the contact lenses and prevents damage thereof.
- the contact lens case further incorporates a pair of coverlids containing a pair of silicon O-ring gaskets. It also incorporates a pair of ridges molded on the top of the receiving cups. When the embodiment is closed, the ridges compress the O-rings, creating an interlocking function preventing leakage. This also prevents other elements from entering the concealed case. Over time, the O-ring's original strength can weaken, flatten or become distorted. The function of the ridges, on top of the receiving cups, is to compensate for the distortion of the O-rings, and to maintain the interlocking tight seal preventing leakage.
- the contact lens case further incorporates two guides on both sides of the top portion of the receiving cups. These guides line up the coverlids to the receiving cups, ensuring proper closure and alignment. This alignment is crucial in preventing leakage of solution.
- the contact lens case further incorporates a hinge that allows the coverlids to remain in an upright position once opened. This allows the user to use one hand for removal and placement of the contact lenses, rather than two as in the prior art mentioned.
- the contact lens case further incorporates a small concave area around the hinge.
- the concave area enables the lid to be opened at a 90° angle, making it convenient to the user for the removal of contact lenses.
- This enhanced shape allows for a stronger connection to the hinge due to the thickened edges in comparison to prior art.
- This thickened design also reduces wear and tear of the lid with repeated use, making the device more durable than prior art.
- the contact lens case further incorporates a closing mechanism.
- This mechanism once closed, locks the coverlids to the receiving cups. This creates the interlocking function, previously mentioned, of the O-rings and ridges on top of the receiving cups.
- the silicon O-rings elasticity creates constant pressure on the lid in the upward direction, locking the closing mechanism. This prevents the solution from leaking out and harmful elements from entering.
- the contact lens case further incorporates a sleek body design. This design enables it to be stored in a variety of places minimizing the possibility of it opening. It also has a smooth finish that provides a “snag-free” case. The sleek design of the closing mechanism prevents the contact lens case from snagging onto items that could cause it to open. It also incorporates an ergonomic design that allows for easy operation while providing a device that can be stored in such areas as travel bags, purses and the like without leakage of solution.

- All prior art of contact lens cases are outdated in design and function. The only prior art that best relates to the present invention is U.S. Pat. No.6,170,664 to Dar. This device best demonstrates a sleek design, however, there are several drawbacks to this prior invention's design, functions and the claims that have been made thereof.
- The first drawback is that the interiors of the receiving cups are completely smooth permitting the contact lenses to adhere to the sidewalls. Furthermore, due to the flat interior base, the contact lenses can also adhere to the bottom of the receiving cups.
- Another drawback is the inconsistency in alignment when opening and closing the prior invention. The alignment is a crucial element because it ensures that the lid is closed in its proper position to prevent solution leakage.
- The prior invention claims a leak proof seal using a rubber ring. The drawback to this is, over time the rubber flattens and the seal is weakened causing the solution to leak out of the embodiment. The flattened rubber ring, in combination with the poor alignment, makes the prior invention incapable of guaranteeing a leak proof device.
- In addition, when the coverlids are open, the user must hold the lid open with one hand while retrieving the contact lenses with the other, making it inconvenient for the user. The hinge of the prior invention does not hold the coverlids tight enough to allow the user to use just one hand for operation.
- Furthermore, the hinge area is weak in design due to an extreme concave area on the coverlids. The concave extends to the edges of the coverlids making the hinge attachment considerably thin. This creates a greater possibility of damage to the hinge area with repeated use.
- These drawbacks are all solved with the present invention.
- The present invention provides a means of storage for contact lenses in a secured environment. Additionally, it is an object of the invention to provide a means of storage for contact lenses that is durable and leak proof. It is another object of the present invention to provide a housing with an ergonomic design for comfort when opening and closing the embodiment.
