AN' APPL7CCATOR DEVICE FOR POSITIONING
A CONTACT LENS ON THE HUMAN EYE
This invention relates to an applicator device for efficiently and accurately placing a contact lens on the outer surface of t:he human eye wherein the device is also capable of supporting the lens for proper and efficient cleaning immediately prior to application of the lens to the eyeball.
In modern day society, many people with poor eyesight now utilize the wearing of contact lens to improve such eyesight rather than conventional spectacles or eye gla;~ses. Advancements in the development and production of contact lens has increased the number of people who can acaually wear the lens and also extended the amount of tame such lenses can be worn. The improvement in contact lens technology has of course made available to wearers of such lenses both the hard lens which was i:irst developed and now the "soft" material lens which presents less aggravation to the eye and can be worn for extended periods.
However, regardless of the type of contact utilized, there is still the recognized problem of properly applying the contact lens to the eyeball. Conventional practice, in the past, has lead to the precarious positioning' of the contact lens on one finger of the user SEK/4.381 and the attempted but haphazard positioning of the lens in proper engagement with the exterior surface of the eyeball. Such a method is not only less than totally effectivel5r but :frequently results in dropped lenses or inaccurate positioning particularly when the contact lens must be properly oriented immediately prior to application to the exterior surface of the eyeball.
As ev~ldence of the fact that this problem has been recognized,, the following United States Patents are representative of various devices which are directed to the application .of a contact lens.
The U.S. Patent to Spriggs 3,177,874 discloses a contacts lens applicator which has a plurality of gear mechanisms which,, when properly manipulated will properly activate a head formed of three upwardly extending prongs effectivel'~ arranged in a circle and having a somewhat of a flare type configuration so that the tips of these prongs are located in a manner to appropriately contact and grip t:he contact lens being applied. Gripping the lens occura by water surface tension. This structure, while appearing to be applicable incorporated numerous mechanical linkage, in the form of gears, which therefore appears to be extremely complicated and therefore effects the operable life as well as the maintenance characteri:~tics of this device.
The Patent t:o England, 4, 097, 081, discloses a device for inserting and removing contact lenses comprising an elongated resilient cylindrical body of small diameter ~'y,.
.~: A
SEK/4.381 2099205 having in its forward end a contact lens holding suction cup. ,A small diameter duct extends entirely through the body which is opened at its forward end and at its opposite end. The squeezing of the body of the device exerts a negative force or suction on a contact lens which is mounted. on the holding suction cup. Further manipulation serves to release the lens in its proper location.
The Patent t:o Richmond, 3,134,208, discloses a lens holding device or more specifically an optical blank holding de~rice utilized for the making of lenses rather than being specifically structured and designed to facilitate the application of such contact lenses to the eye in an E=ffici~ent and accurate manner.
Of se:condany interest is the Patent to Obits, 3,063,083, which is directed to washing or cleansing devices and particularly to a kit for the washing and storing o:E contact lenses. The device does not specifical:Ly relate to a device which serves to properly apply and~'or position contact lens on the exterior surface of the eye in the conventional and accepted fashion.
The above-referenced patents indicate that prior art has made nvumerous attempts to solve the well recognized problem o:E accurately and properly positioning the contact leans on the human eye. However, lack of commercial availability of devices such as this may be an indication that this well recognized problem is not SEK/4.381 2099205 solved by ouch devices. Therefore, there is total recognized need in this area for an applicator assembly which effectively and efficiently positions a contact lens on the human eye in a proper orientation and locatian. :>uch a preferred device should be capable of removably mounting the contact lens on the preferred applicator in a aecure manner so as to eliminate any possibility of inadvertent dislodgement and possible loss of the lens while at the same time supporting or engaging the contact lens in a manner which allows easy transfer of the lens to the: outer surface of the eyeball once the applicator is operatively positioned.
This invention relates to an applicator device which serves to efficiently, effectively, and accurately place a contact ls:ns on the exterior surface of the human eye.
More speci:Eically, the subject applicator assembly comprises a base and a movably mounted applicator number thereon. 'rhe b<~se includes a handle portion and a support por~:ion preferably formed of a single, integral, one piece construcaion. A first channel is centrally and coaxially formed .in the base and extends along the length thereof and completely therethrough. Such first channel is open at both ends and the channel is specifically dimensioned and structurally adapted to receive the applicator member.
The applicator member includes a holding means secured to and o:r defining one end of the applicator.
SEK/4.:381 2099205 The remainder of the applicator is defined by an elongated :aem portion having an exterior transverse dimension sufficient to be mounted on the interior of the first channel and at the same time allow selective sliding movement of the length of the stem within the first channel. This allows the selective positioning of the applicator between a stored position and an operative position.
The holding means is specifically designed to removably mount a~ contact lens thereon by removably but relatively aecure engagement with the exterior surface of the contact: le.ns~. This is accomplished through the provision of a plurality of outwardly extending lands which engage the exterior lens surface. Due to water surface tension between the moistened lens and the confronting surface fo the hands, there is sufficient adhering force ~or pressure to removably secure the contact leas to the plurality of lands of the holding means. This provides proper positioning of the lens and also to allow itsa cleaning. Such cleaning technique of the contact. lens when it engages the holding means and the support: portion of the base is accomplished by the addition of' a saline solution and will be described in greater detail hereinafter. The lands are further adapted collectively define a mounting surface for the engagement of the exterior surface of the contact lens as explained above.
The support. portion of the base has a support a surface formE:d on and defining the outer extremity of the support portion. The specific structural configuration of the holding means on l:he applicator member is adapted to effectively mate with the support portion on the base to the extent that t:he mounting surface on the holding means is positionable into flush engagement with the support surface on the support portion of the base when the applicator is selectively disposed into the aforementioned stored position.
Once in such stored position, the contact lens is wetted and 1C) mounted on the nova flush support surface and mounting surface.
As set forth above, tree adhering Force is the result of water surface tension between confronting or contacting surfaces of the lens and the :support surface and mounting surfaces on the support portion o. the base and the holding means respectively.
It should also be emphasized that when in a stored position, more surface area conta~~ts the exterior surface of the contact lens. Accordingl~l, more adhering force is developed and the contact lens is more stable when both the support surface and the mounting surface c:o:ncurrently engages the outer surface of 2C1 the contact 7_ens. This is due to the fact that greater water surface tens~_on e:~ists. Such adhering force is caused by water surface tension as explained in detail herein and is sufficient to maintain secure engagement even when the lens is positioned in any of a varies=y of attitudes or orientations. Gravity will not dislodge the contact lens from its mounted position. Once the contact 7_ens is pro;oerly cleaned and it is ' SEK/4.:381 2099205 desired to place the contact lens on the eyeball, the applicator .is movable in to the operative position. This operative position is defined by an outer spaced extension of the holding means and more specifically a separation of the mounting surface defined by the plurality of landls from the support surface of the base support portion. The exterior surface of the contact lens thereby breaiks engagement with the support surface of the support portion of the base and therefore has less adhering force exerted thereon because less surface is in actual engagemenit with the lens. The lens, is still maintained securely but removably on the mounting surface as the holding means and plurality of lands move outwardly from the support portion of the base and into the aforementioned outer extension, in spaced relation from the support portion of the base.
A second channel extends completely through the length of the elongated stem and holding means and is coaxially 7_ocated relatively to a central longitudinal axis which extends through the stem and therefore through the holdina~ means. This second channel is open at both ends and is suf:Eiciently large in dimension to allow light to pass therethrough from the outermost exterior end through the .inner end adjacent to which the contact lens is mounted. The light will of course pass through the transparent contact lens. Such light can be easily viewed by the eyeball about to receive the contact lens.
This light: pawing through the second channel is accurately aligned with the contact lens center such that continued viewing by tree eyeball with the light passing through the second channel wi.l7. serve as a sighting and or alignment means to accurately position the contact lens until it physically engages~the exterior surface of the eyeball. Once such engagement or contact occurs, the regular force exerted on the interior surface of: the contact lens through its engagement with the exterior surface of the eyeball will be greater than the force serving to connect or mount the exterior surface of the contact lens to the mounting surface defined by the radially outwardly positioned lens. The contact lens will of course therefore be maintained on the exterior surface of the eyeball once the applicator is removed or selectively positioned back into the aforementioned stored position.
The present invention also includes a container structure with is capable of storage and containment of the applicator assembly therein. An additional feature of this container will be that the cover thereof is structured to define an eye piece which includes a magnifying lens. The eye piece can be fitted over one of the eyes of the user and is used to properly sight and magnify the position of the contact lens on the applicator assembly. Such magnified viewing allows the proper orientation of the lens relative to the applicator so that when it engages the exterior surface of the Bi _....
SEK/4.381 2099205 eyeball, i.t is prope~__~ly oriented relative thereto.

Like reference numerals refer to like parts throughout the several views of the drawings.
As shown in the accompanying figures, the present invention is directed towards an applicator assembly generally indicated as 10 designed to apply a contact lens to the eyeball 12 of a user's eye. The contact lens 14 is mounted in the position best shown in Figure 9 for purposes of cleansing as will be explained in greater detail specifically with reference to Figure 8 and also in such position for purposes of application as best shown in Figurea 7 and 9. It should be noted that while the contact lens is represented in relative dimension and configuration ~~s shown in Figure 9, such contact lens, utilizing the preferred applicator assembly of the present invention may take a variety of dimensions and configurat:ions,, all of which contact lenses are now commercially available.
The subject applicator assembly includes a base generally indicated as 16 and shown in detail in Figures 2 , 3 and 4 . The ba:~e 16 includes a handle portion 18 configured to be effectively gripped by the hands or more specifically the fingers of the user and a support portion 20. The base 16 also includes a first channel 22 extending completely through the length of the base and disposed in substantially coaxial alignment with a central longitudinal axis (not demonstrated for purposes .r: , of clarity). Alsc, the first central channel 22 is open at both ends and is transversely dimensioned so as to slidingly receive therein an applicator member generally indicated as 30.
The base 16 further comprises a 10a SEK/4.381 2099205 plurality of elongated slots 24 and also a plurality of spaced apart recesses as at 26. The slots and the recesses are dimensioned and otherwise adapted and disposed to receive specific portions or components of the applicator member 30, as will be explained in greater detail hereina:Eter 'when such applicator member is disposed in a stored position as best shown in Figures 1 and 7. Further, the support portion includes a support surface 28 which has a somewhat concave configuration so as to be readily adaptable to the convex configuration of the exterior surface of the contact lens 14 when such contact lens is mounted thereon.
The applicator ascsembly, as set forth above, further includes an ap~~licator 30 having an elongated stem 32 with a holding means generally indicated as 34 affixed to and at least p<<rtial:ly defining one end thereof. The opposite end of the stem 32 includes a fixedly or integrally attached stop member 36. The outer transverse dimension of the stem 32 is such as to be slidingly received within the first channel 22 of the base 16.
Therefore, it should be apparent that the applicator 30 is selectively posit.ionable by the hands of the user between a stored position (see Figs. 1 and 7) and an operative position as best shown in Figures 7 and 9. The stop member 36 is provided so as to prevent inadvertent removal or displacement of the stem 32 from passing out of the central ~~hannel 22 of the base 16. It should be apparent theref~~re that the transverse dimension of the SEK/4.381 2099205 stop member 36 is provided so as to prevent inadvertent removal or_ dis~~lacement of the stem 32 from passing out of the central channel 22 of the base 16. It should be apparent there:Eore that the transverse dimension of the stop member 3E. is a.t least somewhat greater than the inner transver:~e dimension of the channel 22.
The holding means 34 includes a head portion as at 38 and a plurality of radially outward extending lands 40 which may be d:ispose~d in spaced relation to one another or otherwise interconnected. Connecting means in the form of spaced apart flange like fingers 42 are directed radially outward from the head 38 and are connected at the upper and outermost extremity to the lands 40. Such flange like finger members 42 have their inner most longitudinal end as at 44 connected or integrally formed on the exterior surface of the stem. The lands are collectively shaped t:o define a somewhat concave surface and they a.re disposed to collectively define what may be referred to as a mounting surface which engages and supports the exterior surface of the contact lens 14 as best shown in l?igura 9.
The aforementioned operative position is defined by the holding melons 34 and particularly the lands 40 and the head portion 38 extending outwardly away from the support portion 20 and particularly the support surface 28 of the bas.. 16. In such a position the stem in manipulated to accomplish such outer positioning wherein the contacts lens 14 :is mounted on and thereby supported SEK/4.381 2099205 exclusively by the lands 40 and in particular the mounting surface 44 collectively defined by the exterior surface of at .Least i~he lens and depending upon the shape of a contact 7_ens, 'the exposed surfaces of the fingers 42.
When in the aforementioned stored position, the mounting surface 44 defined by the exterior, exposed surface collecaively of the plurality of lands 40 is disposed in flvush engagement with the support surface 28 of the support portion 20 of the base 16. This is accomplished by a mating engagement of the flange like fingers 42 within one of a plurality of spaced apart elongated slots 24 disposed in spaced apart relation to one another and integrally formed in the support portion as set forth above. Similarly, a plurality of spaced apart recesses 26 are dimensioned, configured and otherwise structura7.ly adapted to receive the lands 40 therein. The relative dimension and configuration of the recesses 26 and the lands 40 are such as to dispose the mounting surfa~~e 44 into flush relation with the support surface 28 to define an overall somewhat concave configuration when :such flush engagement between these 20 surfaces exists. In such a stored position and when the two above nots:d surfaces are in flush relation to one another, the ~~ontact lens 14 is placed thereon. An adhering force created by water surface tension or force is exerted on t:he exterior surface of the contact lens 14 thereby securely but removably holding the contact lens SEK/4.381 2099205 in an operative: position and in engagement with both the mounting surfaces 44 of the lands and the support surface 28 of the support portion 20. However, when it is desired to physically apply the contact lens 14 to the exterior surface of the eyeball 12, the stem 32 is manipulated relative to the base 16 in a manner which causes the outear extension of the holding means 34 from the support portion 20 of base 16 (see Fig. 9).
In the position shown in Figure 7, the assembly is still in its storec! position. However, when it is desired to phy:aicall:y apply the lens, the holding means 1. 0 34, and particularly the lands 40 extend outwardly in spaced relation from the support portion 20, this causes the mounting surface of the lands 40 to clearly separate in the an outer spaced extension from the support surface 28 and support portion 20 (see dotted lines of Fig. 7 and the details of Fig. S~). It is important to note, and as set forth above in somewhat detail, the adhering force due to the existence of water surface tension is somewhat less when the device is in the outer spaced position since a smaller surface area, namely the surface area of the mounting surfaces of the lands 40 and possibly the 20 exposed surface's of :fingers 42 are only in contact with the outer surface of the contact lens. A greater adhering force due t:o engagement of a greater surface area exists bEatween the lens when in fact both the mounting surfaces 44 of the lands and the support surface 28 of the support portion 20 are in flush engagement SEK/4.381 2099205 and when both engages the outer surface of the contact lens.
It is important to note that the stem 32 as well as the holding means 34 includes a second elongated channel extending completely therethrough and being open at both ends. This channel 50 is disposed in coaxially alignment with a central longitudinal axis of the stem 32. The transverse dimE~nsion of the second channel 50 is such as to allow light to pass therethrough. This light may be viewed as it passes through the contact lens 14 by the eyeball 1.2 immediately prior to the application or physical c:onta~~t of 'the lens 14 to the exterior surface of the eyeball 12. T:he continuous viewing by the eyeball of the light passing 'through the second elongated channel 50 and through the transparent contact lens will serve to automatically align and therefore properly position the contact lens as it approaches, eventually contacts and is transferred on~~o the outer surface of the eyeball 12.
Another feature of the present invention is shown in Figure 8. Where the 7_ens 14 is mounted on both the lands 40 and the sups>ort portion 20 when the applicator 30 and the base 1.6 ars: in the aforementioned stored position, a cleansing fluid may be applied directly to the inner surface 14' of the contact lens 14. Cleansing is readily accomplished. The plurality of drops as at 51 are allowed to pas:. through a certain distance, which may of course vary, but which is preferably outward to six inches above the inner surface 14' when in the ,c, k orientational position ~;hown in Figure 8. Such drops may pass from the conventional cc>ntainer in which such cleansing solutions are sold as at: 53. The splashing of the individual drops 51 onto the inner surface 14' will cause them to "bounce"
or "ricochet" off such inner surface and carry with them when passing from the inner ~;urface 15', any debris or dust which would have a tendency to irritate the eyeball.
15a -- ' SEK/4.381 2099205 The greater. adhering force between the contact lens 14 and the now cc>mbined, flush support surface 28 and mounting surfaccas 44 of the lands 40 will maintain the contact lens 1S6 in :its secured position as shown in Figure 8 even under tlhe pressure exerted thereon by the cleansing drops 51 falling from a significant height or distance. After cleansing the stem 32 is manipulated until the holding means 34 and particularly the lands 40 are disposed in the aforementioned operative position immediately prior to contact between the lens 14 and the eyeball 12. The adhering force on the lens is thereby reduced.
Yet another feature of the present invention is the provision of a container generally indicated as 60. The container includes a substantially hollow interior dimensionally configured to receive and have stored therein the as~:embly 10 preferably when in its stored position. The container 60 includes a cover portion generally indicated as 64 which may more specifically be defined by an eye piece. The eye piece includes an outwardly flars:d surrounding peripheral wall as at 66 having the exterior ~>eripheral rim as at 68 dimensioned to fit over but received in overlying relation to an eyeball of the' user.. The cover structure 64 also includes the existence of a magnifying lens 70. When the cover is properly positioned over the eyeball viewing through the m<ignifying lens 70 will allow enhanced observation of 'the contact lens. The contact lens 14 can SEK/4.381 2099205 thereby be properly o~__~iented by the hands or fingers of the user until it is. accurately positioned so as to accomplish proper placement in covering relation to the eyeball 12. Proper placement and actual contact of the lens 14 occurs as shown in Figure 7 when the line or sight of the e~,~eball 12 passes through the elongated second channel ~i0 by constantly viewing the light.
The cover 64 is removably attached in overlying, covering relation to the open end or mouth 69 of the container Ei0 as shown.
Now that the inmention has been described,

The lens, is still maintained securely but removably on the mounting surface as the holding means and plurality of lands move outwardly from the support portion of the base and into the aforementioned outer extension, in spaced relation from the support portion of the base.
A second channel extends completely through the length of the elongated stem and holding means and is coaxially 7_ocated relatively to a central longitudinal axis which extends through the stem and therefore through the holdina~ means. This second channel is open at both ends and is suf:Eiciently large in dimension to allow light to pass therethrough from the outermost exterior end through the .inner end adjacent to which the contact lens is mounted. The light will of course pass through the transparent contact lens. Such light can be easily viewed by the eyeball about to receive the contact lens.
This light: pawing through the second channel is accurately aligned with the contact lens center such that continued viewing by tree eyeball with the light passing through the second channel wi.l7. serve as a sighting and or alignment means to accurately position the contact lens until it physically engages~the exterior surface of the eyeball. Once such engagement or contact occurs, the regular force exerted on the interior surface of: the contact lens through its engagement with the exterior surface of the eyeball will be greater than the force serving to connect or mount the exterior surface of the contact lens to the mounting surface defined by the radially outwardly positioned lens. The contact lens will of course therefore be maintained on the exterior surface of the eyeball once the applicator is removed or selectively positioned back into the aforementioned stored position.
The present invention also includes a container structure with is capable of storage and containment of the applicator assembly therein. An additional feature of this container will be that the cover thereof is structured to define an eye piece which includes a magnifying lens. The eye piece can be fitted over one of the eyes of the user and is used to properly sight and magnify the position of the contact lens on the applicator assembly. Such magnified viewing allows the proper orientation of the lens relative to the applicator so that when it engages the exterior surface of the Bi _....
SEK/4.381 2099205 eyeball, i.t is prope~__~ly oriented relative thereto.

Like reference numerals refer to like parts throughout the several views of the drawings.
As shown in the accompanying figures, the present invention is directed towards an applicator assembly generally indicated as 10 designed to apply a contact lens to the eyeball 12 of a user's eye. The contact lens 14 is mounted in the position best shown in Figure 9 for purposes of cleansing as will be explained in greater detail specifically with reference to Figure 8 and also in such position for purposes of application as best shown in Figurea 7 and 9. It should be noted that while the contact lens is represented in relative dimension and configuration ~~s shown in Figure 9, such contact lens, utilizing the preferred applicator assembly of the present invention may take a variety of dimensions and configurat:ions,, all of which contact lenses are now commercially available.
The subject applicator assembly includes a base generally indicated as 16 and shown in detail in Figures 2 , 3 and 4 . The ba:~e 16 includes a handle portion 18 configured to be effectively gripped by the hands or more specifically the fingers of the user and a support portion 20. The base 16 also includes a first channel 22 extending completely through the length of the base and disposed in substantially coaxial alignment with a central longitudinal axis (not demonstrated for purposes .r: , of clarity). Alsc, the first central channel 22 is open at both ends and is transversely dimensioned so as to slidingly receive therein an applicator member generally indicated as 30.
The base 16 further comprises a 10a SEK/4.381 2099205 plurality of elongated slots 24 and also a plurality of spaced apart recesses as at 26. The slots and the recesses are dimensioned and otherwise adapted and disposed to receive specific portions or components of the applicator member 30, as will be explained in greater detail hereina:Eter 'when such applicator member is disposed in a stored position as best shown in Figures 1 and 7. Further, the support portion includes a support surface 28 which has a somewhat concave configuration so as to be readily adaptable to the convex configuration of the exterior surface of the contact lens 14 when such contact lens is mounted thereon.
The applicator ascsembly, as set forth above, further includes an ap~~licator 30 having an elongated stem 32 with a holding means generally indicated as 34 affixed to and at least p<<rtial:ly defining one end thereof. The opposite end of the stem 32 includes a fixedly or integrally attached stop member 36. The outer transverse dimension of the stem 32 is such as to be slidingly received within the first channel 22 of the base 16.
Therefore, it should be apparent that the applicator 30 is selectively posit.ionable by the hands of the user between a stored position (see Figs. 1 and 7) and an operative position as best shown in Figures 7 and 9. The stop member 36 is provided so as to prevent inadvertent removal or displacement of the stem 32 from passing out of the central ~~hannel 22 of the base 16. It should be apparent theref~~re that the transverse dimension of the SEK/4.381 2099205 stop member 36 is provided so as to prevent inadvertent removal or_ dis~~lacement of the stem 32 from passing out of the central channel 22 of the base 16. It should be apparent there:Eore that the transverse dimension of the stop member 3E. is a.t least somewhat greater than the inner transver:~e dimension of the channel 22.
The holding means 34 includes a head portion as at 38 and a plurality of radially outward extending lands 40 which may be d:ispose~d in spaced relation to one another or otherwise interconnected. Connecting means in the form of spaced apart flange like fingers 42 are directed radially outward from the head 38 and are connected at the upper and outermost extremity to the lands 40. Such flange like finger members 42 have their inner most longitudinal end as at 44 connected or integrally formed on the exterior surface of the stem. The lands are collectively shaped t:o define a somewhat concave surface and they a.re disposed to collectively define what may be referred to as a mounting surface which engages and supports the exterior surface of the contact lens 14 as best shown in l?igura 9.
The aforementioned operative position is defined by the holding melons 34 and particularly the lands 40 and the head portion 38 extending outwardly away from the support portion 20 and particularly the support surface 28 of the bas.. 16. In such a position the stem in manipulated to accomplish such outer positioning wherein the contacts lens 14 :is mounted on and thereby supported SEK/4.381 2099205 exclusively by the lands 40 and in particular the mounting surface 44 collectively defined by the exterior surface of at .Least i~he lens and depending upon the shape of a contact 7_ens, 'the exposed surfaces of the fingers 42.
When in the aforementioned stored position, the mounting surface 44 defined by the exterior, exposed surface collecaively of the plurality of lands 40 is disposed in flvush engagement with the support surface 28 of the support portion 20 of the base 16. This is accomplished by a mating engagement of the flange like fingers 42 within one of a plurality of spaced apart elongated slots 24 disposed in spaced apart relation to one another and integrally formed in the support portion as set forth above. Similarly, a plurality of spaced apart recesses 26 are dimensioned, configured and otherwise structura7.ly adapted to receive the lands 40 therein. The relative dimension and configuration of the recesses 26 and the lands 40 are such as to dispose the mounting surfa~~e 44 into flush relation with the support surface 28 to define an overall somewhat concave configuration when :such flush engagement between these 20 surfaces exists. In such a stored position and when the two above nots:d surfaces are in flush relation to one another, the ~~ontact lens 14 is placed thereon. An adhering force created by water surface tension or force is exerted on t:he exterior surface of the contact lens 14 thereby securely but removably holding the contact lens SEK/4.381 2099205 in an operative: position and in engagement with both the mounting surfaces 44 of the lands and the support surface 28 of the support portion 20. However, when it is desired to physically apply the contact lens 14 to the exterior surface of the eyeball 12, the stem 32 is manipulated relative to the base 16 in a manner which causes the outear extension of the holding means 34 from the support portion 20 of base 16 (see Fig. 9).
In the position shown in Figure 7, the assembly is still in its storec! position. However, when it is desired to phy:aicall:y apply the lens, the holding means 1. 0 34, and particularly the lands 40 extend outwardly in spaced relation from the support portion 20, this causes the mounting surface of the lands 40 to clearly separate in the an outer spaced extension from the support surface 28 and support portion 20 (see dotted lines of Fig. 7 and the details of Fig. S~). It is important to note, and as set forth above in somewhat detail, the adhering force due to the existence of water surface tension is somewhat less when the device is in the outer spaced position since a smaller surface area, namely the surface area of the mounting surfaces of the lands 40 and possibly the 20 exposed surface's of :fingers 42 are only in contact with the outer surface of the contact lens. A greater adhering force due t:o engagement of a greater surface area exists bEatween the lens when in fact both the mounting surfaces 44 of the lands and the support surface 28 of the support portion 20 are in flush engagement SEK/4.381 2099205 and when both engages the outer surface of the contact lens.
It is important to note that the stem 32 as well as the holding means 34 includes a second elongated channel extending completely therethrough and being open at both ends. This channel 50 is disposed in coaxially alignment with a central longitudinal axis of the stem 32. The transverse dimE~nsion of the second channel 50 is such as to allow light to pass therethrough. This light may be viewed as it passes through the contact lens 14 by the eyeball 1.2 immediately prior to the application or physical c:onta~~t of 'the lens 14 to the exterior surface of the eyeball 12. T:he continuous viewing by the eyeball of the light passing 'through the second elongated channel 50 and through the transparent contact lens will serve to automatically align and therefore properly position the contact lens as it approaches, eventually contacts and is transferred on~~o the outer surface of the eyeball 12.
Another feature of the present invention is shown in Figure 8. Where the 7_ens 14 is mounted on both the lands 40 and the sups>ort portion 20 when the applicator 30 and the base 1.6 ars: in the aforementioned stored position, a cleansing fluid may be applied directly to the inner surface 14' of the contact lens 14. Cleansing is readily accomplished. The plurality of drops as at 51 are allowed to pas:. through a certain distance, which may of course vary, but which is preferably outward to six inches above the inner surface 14' when in the ,c, k orientational position ~;hown in Figure 8. Such drops may pass from the conventional cc>ntainer in which such cleansing solutions are sold as at: 53. The splashing of the individual drops 51 onto the inner surface 14' will cause them to "bounce"
or "ricochet" off such inner surface and carry with them when passing from the inner ~;urface 15', any debris or dust which would have a tendency to irritate the eyeball.
15a -- ' SEK/4.381 2099205 The greater. adhering force between the contact lens 14 and the now cc>mbined, flush support surface 28 and mounting surfaccas 44 of the lands 40 will maintain the contact lens 1S6 in :its secured position as shown in Figure 8 even under tlhe pressure exerted thereon by the cleansing drops 51 falling from a significant height or distance. After cleansing the stem 32 is manipulated until the holding means 34 and particularly the lands 40 are disposed in the aforementioned operative position immediately prior to contact between the lens 14 and the eyeball 12. The adhering force on the lens is thereby reduced.
Yet another feature of the present invention is the provision of a container generally indicated as 60. The container includes a substantially hollow interior dimensionally configured to receive and have stored therein the as~:embly 10 preferably when in its stored position. The container 60 includes a cover portion generally indicated as 64 which may more specifically be defined by an eye piece. The eye piece includes an outwardly flars:d surrounding peripheral wall as at 66 having the exterior ~>eripheral rim as at 68 dimensioned to fit over but received in overlying relation to an eyeball of the' user.. The cover structure 64 also includes the existence of a magnifying lens 70. When the cover is properly positioned over the eyeball viewing through the m<ignifying lens 70 will allow enhanced observation of 'the contact lens. The contact lens 14 can SEK/4.381 2099205 thereby be properly o~__~iented by the hands or fingers of the user until it is. accurately positioned so as to accomplish proper placement in covering relation to the eyeball 12. Proper placement and actual contact of the lens 14 occurs as shown in Figure 7 when the line or sight of the e~,~eball 12 passes through the elongated second channel ~i0 by constantly viewing the light.
The cover 64 is removably attached in overlying, covering relation to the open end or mouth 69 of the container Ei0 as shown.
Now that the inmention has been described,
