It should be noted that different references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
The present disclosure relates to a product that employs a simple “dipping, rubbing and cleansing” method of cleaning a contact lens in a convenient, quick and easily disposable manner. The product includes a dual compartment, with one compartment used to dip, rub and cleanse a contact lens and the other compartment is used to store a single use utility to sanitize the hands before touching the contact lens. The product of the present disclosure can be taken on remote locations for use without the otherwise necessary bulk of a large size container because of the small size of the product. The product is designed to be able to carry in pockets or handbags during travel with anticipation of need.
The present disclosure also relates to a cleansing solution. The cleansing solution includes a combination of saline solution, Euphrasia (Eyebright), and/or CBD. The cleansing solution is able to rinse a contact lens while also nourishing the eyes.
The inventor of the present disclosure has found that to address some of the issues described herein, a cleansing device includes a lens cleaning solution in one compartment with nourishing properties for the contact lens, while the other compartment includes a hand cleaning utility allowing for sanitary use. The cleansing device of the present disclosure may be a disposable pouch. The disposable pouch may be made from an eco-friendly film to protect the contents from contaminants.
The cleansing device described herein includes a first compartment and a second compartment. The first compartment houses the nourishing cleansing solution for the contact lens rinse, while the second compartment houses the utility to sanitize the hands. The utility may include a wipe. The wipe may be a disinfectant wipe. The wipe may be a premoistened wipe including alcohol. The alcohol may be isopropyl alcohol.
As used herein, “about” refers to any values that are within a variation of ±10%, such that “about 10” would include from 9 to 11. As used herein, “a,” “an,” or “the” refers to one or more, unless otherwise specified. Thus, for example, reference to “a component” includes a single component as well as a mixture of two or more different components, and the like.
Recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range, unless otherwise indicated herein, and each separate value is incorporated into the specification as if it were individually recited herein. All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context.
The use of any and all examples, or exemplary language (e.g., “such as”) provided herein, is intended merely to illuminate certain materials and methods and does not pose a limitation on scope. No language in the specification should be construed as indicating any non-claimed element as essential to the practice of the disclosed materials and methods.
According to an embodiment, a single-use cleansing device is provided. The cleansing device includes two-separate, sealed compartments. The compartments may be connected at their distal ends with a fold-seal arrangement so that the compartments may be collapsed or folded in a billfold fashion. Each compartment is sealed to prevent the egress of dirt or moisture, or to maintain the stability of the cleansing solution.
The single-use cleansing device may include a first compartment and a second compartment, wherein the first compartment may include a wipe, and the second compartment may include a cleansing solution comprising Euphrasia. The wipe may be a pre-moistened wipe or may be a dry, absorbent wipe. In some embodiments, a pre-moistened wipe may include a moistening agent, such as isopropyl alcohol. Isopropyl alcohol is known for its cleaning and germ-killing ability, thus making it suitable for use to clean a user's hands when handling contact lens. Additionally, isopropyl alcohol is not harmful to humans when used externally and dries in a few seconds, such that it does not effect the user when handling contacts near the eye area. It should be understood that other similar non-toxic moistening agents may be used if desired.
In some embodiments, the wipe may be dimensioned in a convenient 6×6 inch size, folded to 2×2 inches. The wipes may be fabricated from any soft, pliable material that is used in the industry. For simplicity, the cleansing device will be described as including a single wipe in the compartment. However, it should be understood that compartment may be modified to hold multiple wipes. In some embodiments, the cleansing device and/or the wipe may be fabricated from biodegradable material, such that the device and wipe may be safely disposed.
The cleansing device described herein is compact and its folded state can easily be accommodated in a purse, pocket, vending situations, etc. In its unfolded state, the cleansing device may be accommodated in the billfold of a wallet. The cleansing device may be easily accessed and safely disposed after use. In some embodiments, the cleansing device may be able to stand vertically. In some embodiments, the cleansing device may be able to close after being able through a closing feature. The closing feature may be a zip lock feature.
