The present invention relates to contact lens cases and covers and, more particularly, to systems and methods of drying and storing contact lens storage cases.
Most contact lens wearers understand the importance of cleaning their contacts or contact lenses on a daily basis. Cleaning and disinfecting contacts on a daily basis extends the life of the contacts and reduces the risk of developing a potentially dangerous eye infection. A contact lens case, which is the “home” of the lenses during periods of nonuse, such as overnight, should be thought of as an extension of the contact lens, and should also be thoroughly cleaned on a regular basis.
Contacts lens cases can be a significant source of microbial contamination. To help prevent eye infections, contact lens cases should be cleaned, rinsed and properly dried every day, particularly after the contacts are removed from the case and placed in the eyes for the day.
Cleaning a contact lens case generally involves removing any solid matter or debris that may have fallen into the case, rinsing each section of the case, including the lids or caps, with the hot water or with same contact lens cleaning solution used to clean and disinfect the contacts. After cleaning, the contact lens case, including the lids or caps, must be thoroughly dried to prevent bacteria formation. Some people dry the sections of the contact lens case by wiping them with a dry cloth, or by placing the contact lens case components upside down on a clean towel. These drying techniques are generally not recommended because they can lead to microbial contamination that can, in turn, lead to painful eye infections. Furthermore, air-drying by simply placing the contact lens case components on a clean towel is often unsatisfactory as the towel does not provide a secure support for the components, which often leads to the contact lens case components falling to the floor or into the sink. Other people close the contact lens wet which does not allow for proper drying, or lay them flat on dirty bathroom counter or sink edge, both of which can lead to microbial contamination. If cases are laid open face up they are also slow to dry and are exposed to contaminants getting in such as dust, hairspray, germs, and the like. If the sections of the case are laid open face down on a flat surface they are substantially isolated from airflow to dry properly, which can also lead to microbial formation. Furthermore, in households where numerous people wear contact lenses, keeping each person's contact lens case components separate after cleaning and drying to prevent mismatching is particularly challenging, especially when they are cleaned at the same time.
According to the principle of the invention, a drying rack and contact lens storage case assembly includes a drying frame, and a contact lens storage case assembly. The contact lens storage case assembly consists of a base formed with first and second receptacles, and first and second caps relating to the first and second receptacles, respectively. The first and second receptacles are externally threaded, and the first and second caps of internally threaded. The first receptacle has a first inner diameter, and the second receptacle has a second inner diameter equal to the first inner diameter of the first receptacle. The first cap has a third inner diameter, and the second cap has a fourth inner diameter equal to the third inner diameter of the first cap. The third and fourth diameters of the first and second caps are each somewhat larger than each of the first and second diameters of the first and second receptacles, respectively. The drying frame has a lower face and an opposed upper face formed with opposed first and second patterns of protuberances relating to the first and second inner diameters of the first and second receptacles, respectively, and opposed third and fourth patterns of protuberances. The third pattern of protuberances relates to the third inner diameter of the first cap, and the fourth pattern of protuberances relates to the fourth inner diameter of the second cap. The first and second receptacles of the base of the contact lens storage case assembly are concurrently positionable on the first and second patterns of protuberances, the first cap is positionable on the third pattern of protuberances, and the second cap is positionable on the fourth pattern of protuberances, wherein the first pattern of protuberances is to extend into the first receptacle and is to be concurrently received against the first inner diameter of the first receptacle, the second pattern of protuberances is to extend into the second receptacle and is to be concurrently received against the second inner diameter of the second receptacle, the third pattern of protuberances is to extend into the first cap and is to be concurrently received against the third inner diameter of the first cap, and the fourth pattern of protuberances is to extend into the second cap and is to be concurrently received against the fourth inner diameter of the second cap. At least one ventilation opening is formed through the drying frame from the lower face to the upper face within each of the first, second, third, and fourth patterns of protuberances to provide drying ventilation. Supporting feet are formed in the lower face of the drying frame, which may be directed against a support surface to support the drying frame at an elevated location relative to the support surface.
The drying frame has a marginal perimeter edge encircling the first, second, third, and fourth patterns of protuberances. An upstanding support is attached to a length of the marginal perimeter edge. The support projects upward relative to the upper face of the drying frame, and there is identifying indicia carried by the support. In a particular embodiment, the identifying indicia are applied to a plate carried by the support. The plate is a separate and discreet component relative to the support, and is removably coupled to the support in a particular embodiment.
In the installation of the contact lens storage case assembly to the drying frame, the first and second receptacles of the base of the contact lens storage case assembly are concurrently deposited on the first and second patterns of protuberances, the first cap is deposited on the third pattern of protuberances, and the second cap is deposited on the fourth pattern of protuberances, wherein the first pattern of protuberances extends into the first receptacle and is concurrently received against the first inner diameter of the first receptacle, the second pattern of protuberances extends into the second receptacle and is concurrently received against the second inner diameter of the second receptacle, the third pattern of protuberances extends into the first cap and is concurrently received against the third inner diameter of the first cap, and the fourth pattern of protuberances extends into the second cap and is concurrently received against the fourth inner diameter of the second cap. Preferably, there is at least one ventilation opening formed through the drying frame from the lower face to the upper face within each of the first, second, third, and fourth patterns of protuberances providing drying ventilation for the first receptacle, the second receptacle, the first cap, and the second cap, respectively.
In yet a further embodiment, there is a support platform having a lower surface formed with supporting feet and an opposed upper surface formed with recesses arranged to concurrently accept the supporting feet formed in the lower face of the drying frame. The support platform has a marginal perimeter edge encircling the recesses formed in the upper surface of the support platform, an upstanding support is attached to a length of the marginal perimeter edge of the support platform, the support projects upward relative to the upper surface of the support platform, and identifying indicia is carried by the support. Ventilation openings are formed through the support platform from the lower surface to the upper surface to provide drying ventilation.
