LENS HOLDER DEVICE WITH CUP CLOSURE AND LOCKING TO A CLOSED BOTTLE WITH VARIABLE INTERIOR VOLUME, METHOD AND METHOD.

LENS HOLDER DEVICE WITH CUP CLOSURE AND LOCKING TO A CLOSED BOTTLE WITH VARIABLE INTERIOR VOLUME, METHOD AND METHOD.

When wearing contact lenses, deposits form on their surfaces and in their microscopic pores. These deposits essentially contain constituents of the lacrimal fluid, such as mucins, lipids, proteins and their compounds, as well as insoluble salts. But also microorganisms, called germs, such as bacteria, mycoses, spores adhere to the lenses and proliferate there. These deposits are likely to cause irritation and inflammation of the eye, in some cases having serious sequelae.

It is therefore essential to clean and decontaminate or sanitize the lenses at regular intervals, preferably every day after wearing them.

Cleaning and sanitizing must remove deposits and kill germs adhering to the lens. For this purpose, liquid or semi-liquid cleaning products are commonly used. A known maintenance system uses a semi-liquid cleaner, a decontaminating soaking solution and a lens storage case.

The so-called manual or mechanical cleaner of this system consists of a slightly viscous solution containing as essential ingredients surfactants dissolved in purified water, but possibly also particles with an abrasive effect in suspension. The decontaminating soaking solution contains as essential ingredients isotonizing salts, pH buffers and germicidal agents dissolved in purified water, as well as possibly viscosifying agents and / or lubricating agents.

During maintenance operations, the lens wearer first unscrews the cap of the small bottle of cleaner, then the cap of the decontaminate solution bottle, then finally unscrews the caps of his lens holder. Then, he removes a lens from the eye, places it in the palm of his hand and pours a few drops of cleaner from the small bottle on each side of the lens to then gently massage it with the index finger of the other hand, describing a circular movement, in order to dissolve and emulsify most of the deposits adhering to the lens. Then, the user tumbles the bottle of decontaminating solution and squirts a flow of solution on both sides of the lens, in order to rinse the solubilized and emulsified deposits. Then the lens wearer places the lens thus maintained in a cup of his lens holder and he pours a dose of decontaminating soaking solution into it so as to completely immerse the lens. This whole series of operations is then repeated for the other lens. Finally, the lens wearer must close the small bottle of cleaner, the large bottle of decontaminate solution and the two cups of the storage case. This requires screwing or clipping four caps.

After the time required to decontaminate the lenses, determined based on the microbicidal strength of the soaking solution, the lenses are ready to be worn again. To remove them from the case, the lens wearer must unscrew or unclip the caps of the two cups of the case. After resting his lenses on his eyes, he throws away the used solution, rinses the case with water, dries it and closes it again.

This maintenance system, although of simplified design compared to the previous systems, is perceived by a large number of lens wearers as tedious and time-wasting. In the first line, the fact of having to open and close, that is to say unscrew and screw again, or unclip and reclip the two bottles and the two compartments of the maintenance case, is perceived as particularly annoying. As a result, many lens wearers do not follow the maintenance procedure strictly, or they do not maintain their lenses after each wear. Unfortunately, lenses that have not been conscientiously maintained can be a source of lens intolerance, irritation or inflammation of the eyes requiring intervention by the ophthalmologist. On the other hand, the interview being perceived as annoying means that many lens wearers abandon the lenses after a period of initiation.

A more recent maintenance system implements a unique solution combining cleaning and decontaminating soaking ingredients, and a lens storage case. This solution contains surfactants relatively well tolerated by the eye, but it is free of abrasive particles. The maintenance operations are similar to those of the system described above, and are distinguished from it only by the fact that the unique solution is used as well for manual cleaning of the lens in the palm of the hand , only for soaking decontaminating lenses in the storage case. The implementation of a combined solution removes the small bottle of cleaner and simplifies operations a little. However, even this lighter system is still perceived by the majority of lens wearers as too complicated in handling, with the same lax behavior regarding lens maintenance and the same unfortunate consequences.

Note that the bottle containing the maintenance liquid and the lens holder are two separate objects, but used together.

In addition to the numerous manipulations of the bottle caps and the lens holder, the operations require tumbling the bottle in order to fill the cups. This filling is done on sight, that is to say that the lens wearer must aim the cups well, squirt the liquid and stop when the filling mark is reached. These operations therefore require a certain dexterity and concentration, which is perceived as annoying by the wearer of lenses.

The bottles of cleaning liquid and decontaminating soaking solution contain on average a sufficient volume of cleaning product for daily maintenance for a period of thirty days. The lens wearer is therefore expected to purchase a new set of products every thirty days. Until recently, the wearer of lenses has never been required to replace their storage case at regular intervals. It was used continuously for six, twelve or twenty-four months, or even for years. However, recent research has shown that the storage case is an ideal place for the proliferation of germs, and that often eye inflammation is due to secondary contamination of the lenses by the germs embedded in the case. Hence there has been a trend recently to recommend replacing the case every three months, or even every month.

The present invention overcomes the aforementioned drawbacks, in that it provides a lens holder device attached to a bottle and allowing manual cleaning of the lenses, as well as their decontaminating conservation, by a metering and directional system. a liquid flow pumped by a simple manual gesture.

There is a pump device attached to a bottle used in a hospital environment with a bowl overhanging the bottle and which can be filled with a dose of disinfectant to soak a cotton ball.

This device could not however be used in any case for the maintenance of contact lenses, since it is my function and too rudimentary in its concept. D has in particular the drawback of having only a single-place bowl, which in addition is supplied by an orifice located in the bottom of the bowl. A lens placed in such a bowl would not fail to deposit debris in this orifice and its supply duct, which would very quickly transform the bowl into a source of contamination, when on the contrary we would like it to be used for decontamination lenses.

Another major drawback of this device is the fact that it is impossible, by actuating its pump, to direct a jet of liquid outwards, in particular in the palm of the hand to carry out manual cleaning of the lens. However, microbiological studies emphasize the capital importance of manual manual cleaning of the lenses, since it is this operation that releases the lenses from almost 80 to 90% of microorganisms, or germs, which allows the use of a product. less aggressive decontaminant soaking, therefore well tolerated by the eye.

In addition, this device does not have a non-removable protective cover, since it is not designed to receive and conserve objects for the purpose of their conservation and decontamination under conditions of good hygiene, it that is to say sterility.

It emerges from this that the device described cannot in any way ensure the maintenance of contact lenses in accordance with pharmacopoeial standards, and it cannot in any way overcome the disadvantages described relating to the procedures and devices currently in force for maintenance. contact lenses.

It is therefore a main object of the present invention to provide a stowed or ammable lens holder at the top of a debitage bottle having a cup device in two locations, the lens holder stowed in the bottle allowing by a gesture of pumping the liquid contained in the bottle, either to direct an outside jet on the lens placed in the palm of a hand for manual cleaning, or to supply liquid to the wells in order to keep the lenses there for decontamination .

It is another object of the present invention to provide a lens holder stowed or stowable at the top of a debitage bottle similar to the previous one, the lens holder having a movable cover making it possible to discover or close a play of 'supply and spray orifices by moving the cover between useful positions essentially uncovering respectively closing the receiving cups of the lenses.

It is another object of the present invention to increase the hygiene of the parts of the lens holder in direct contact with the lenses.

Π is another object of the present invention to provide lens holders stowed or stowable to respective respective bottles, the internal volume of which is reduced when the liquid is delivered.

It is another object of the present invention to provide lens holders stowed or stowable to corresponding bottles, making it possible to reuse the recoverable parts. The first main object is achieved by providing a lens holder stowable at the top of a debitage bottle and having a cup device at two locations allowing to accommodate a pair of lenses, a dosing pump device allowing the choice of '' supply the two cups with liquid or squirt a jet of liquid to the outside, depending on the position of a device for selecting the path of the flow of pumped liquid, and having a cover device for the cups.

The second object of the invention is achieved by providing a lens holder like the previous one, the cover device of which is a movable hood with lights covering the lens holder and making it possible to uncover or close the cups according to its position, said cover being connected to a supply duct supplied by the metering pump and having debitage orifices communicating with an external spray nozzle when the cover is in a first position, preferably corresponding to the uncovering of the cups, and communicating with conduits feeding the cups when the cover is in a second position, preferably corresponding to the partial uncovering or partial closure of the cups, and not communicating with any orifice when the cover is in the closed or closed position of the cups.

The third object is achieved by providing lens holders having cups which can be lined with removable interior linings which can be replaced frequently while keeping the body of the lens holders intact.

The fourth object is achieved by providing a bottle with compressible internal volume under the effect of an external force, for example under the effect of atmospheric pressure, in particular by compression of a pocket containing the liquid to be dispensed, or by displacement a movable piston inside the bottle.

The fifth object is achieved by providing a lens holder having corresponding reversible connection members between the parts to be replaced respectively to be recovered.

These objects, as well as other implicit objects, and their achievements will become apparent on reading the description of the present invention describing certain embodiments of the invention, drawings supported.

In the following, certain preferred embodiments of the invention are described in detail, with the aim of explaining the principles of construction and operation thereof, without however the invention being limited to these configurations alone.

Figures 1 to 9 show the same embodiment in different service positions and in different views.

Figures 1 to 4 and 7 show this embodiment in its so-called "external spraying" position, and these figures will be used to detail the constituent elements of this embodiment. Figures 5 and 8 show the so-called "filling" or "feeding" position and Figures 6 and 9 show the so-called "storage" position.

Figure 1 is in duplicate la and lb, the first board mainly indexing the organs of the lens holder device with cup closure, the second board especially indexing the organs of the dosing pump. Figure 1 bis is identical to Figures la and lb and is used to show the location of sections AA, BB and CC.

The metering and cup closure lens holder device shown in FIG. 1 in the "external spraying" position contains a lens holder body 1 capped with a cover 2 fixed to the body 1 in a movable manner. The lens holder body 1 contains a cup device at two locations 1a, 1b, in which a pair of contact lenses can be placed, in particular a lens in each cup. The cups 1a, 1b are in communication with a supply device 3a, 3b which can be supplied by a supply port orifice 8 when the lens holder is in the so-called "supply" position. The body 1 of the lens holder carries a conduit 4 called "debitage" or "external spraying". In other embodiments, this is lacking.

The cover 2 is provided with two openings 2a, 2b having essentially the shape of the upper openings of the wells la, lb, these openings 2a, 2b coinciding with the wells la, lb in the so-called outer gicalge position. The cover 2 is held on the lens holder body 1 by means of a set of pins 33a, 33b, 33c integral with the cover 2 and capable of sliding under the lower peripheral guide surface of the lens holder body 1. It goes without saying that a set of pins could slide in one or more respective grooves arranged in the outer peripheral wall of the lens-carrying body 1, which would be an alternative solution for sliding maintenance between the two parts. The sliding fixing system makes it possible to rotate the cover 2 relative to the lens-carrying body 1, and sets of small clips placed at the appropriate locations 34a, 34b, 34c allow the cover 2 to be temporarily held in functional positions. If the set of studs 33a, 33b, 33c contains three studs as is the case in the figure, these are advantageously distributed around the periphery of the lens holder body 1.

The lens holder body 1 has in its central region a passage in which is placed a pipe with a supply duct 5 integral with the cover 2. Said passage marries the pipe 5 placed there and serves as a bearing for rotation on the cover 2, the pipe 5 can rotate in said passage. In FIG. 1, the cover 2 and the central pipe with supply duct 5 are made in one piece, but obviously these two members can be in two pieces assembled by usual means. The pipe 5 is completely closed, except that it contains an external debitage or gicalge orifice 6, a supply orifice 8 for the cups and a supply orifice 23, the latter being in communication with an intermittent supply valve 21 The spray port 6 is in communication with the inner end of the spray duct 4, in the position of the supply pipe 5, that is to say the position of the cover 2, shown in FIG. 1. The peripheral wall of the cover 2 contains a directional orifice 7 which is in communication with the external end of the spray duct 4 in said position of the cover 2. The supply orifice 8 is, in the position of the cover 2 shown, closed by the wall of the central passage of the lens holder 1. In this configuration, when liquid is pumped through the supply port 23, it rises in the supply duct 5, then it has no other choice than going through the external debitage device, so by the spraying orifice 6 of the supply pipe 5, then by the spraying duct 4 carried by the lens holder body 1, and finally by the directional orifice 7 of the cover 2. This configuration therefore makes it possible to squirt towards the the pumped liquid outside, and in practice, it is used to squirt liquid in the palm of the hand, to clean the lenses, and to squirt liquid on the cleaned lenses in order to rinse them.

The pumping of the liquid is ensured by a pump 13 having a discharge valve 21 and a suction valve 25.

The suction end of the suction valve 25 plunges permanently into the liquid to be pumped enclosed by the bottle 14. In the embodiment of the invention shown in FIGS. 1 to 19, the bottle is double-walled , the inner wall of which contains a deformable pocket 29 filled with the liquid to be delivered. This pocket is subjected to the effect of an external force, in particular for example to the effect of atmospheric pressure, since it communicates with the ambient air by means of at least one sniffer hole 30a, 30b, 30c , in particular when liquid is delivered by the deformable pocket 29. The outer wall 14 of the bottle device serves to reinforce the construction, and the rim of the deformable pocket 29 is taken between the upper edge of the neck of the bottle and the rim of the pump, the securing and sealing of the interior volume of the deformable pocket 29 being here provided by tightening the cap 11 on the bottle. Those skilled in the art note that this is only an example of a fastener and that other judicious means of assembly exist. The rim of the sandwiched pocket 29 is preferably reinforced but flexible, so as to adapt to the surfaces which hold it to seal the pocket 29 which is otherwise deformable.

One of the other assemblies is shown in FIG. 31. It can be seen there that the deformable pocket is attached by its neck to the body of the pump 16. In order to carry out this assembly, a deformable pocket is made, preferably having a reinforced neck of slightly inner diameter. smaller than the outside diameter of the pump body 16, and the latter is threaded into the neck of the pocket 29 by forcing. In this way it is possible to seal said pocket. Otherwise, incidentally or alternatively, the neck of the bag 29 can be thermally or chemically bonded to the pump body 16.

The discharge and suction valves 25 each have a valve cylinder, the diameter and the height of which are greater than the diameter of a ball 24; 28 respective housed in each valve. These have a lower seat 22; 27 forming a sealable orifice with the ball 24; 28 respective, when it rests on said seat.

At the upper end, the valves 21.25 have a permeable reception seat 23; 26 forming a debit opening. The non-watertight nature of the occlusion between the ball 24; 28 and its upper seat 23; 26 can be ensured by clearances on the periphery of the seat situated outside the bearing perimeter of each ball 24; 28.

In certain embodiments, these valves use the gravity effect of the closing balls 28, 24 and the pressure of the respective column of liquid overhanging each of said balls. Preferably, the sealing of said valves by the respective balls is reinforced by the presence of a respective spring tending to hold its ball in the closing seat thereof.

Figures la, lb show the location of a retaining spring 28r in the suction valves, as well as a retaining spring 24r in the discharge valves Figures IA and IB show enlargements of the pump device 65 communicating with its two valves 25 and 21 of FIGS. 1a and 1b, this for the purpose of clarity.

Figures 20a and 20b show the discharge and suction valves respectively of the metering pump 15, each provided with a holding spring.

These figures are enlargements of the valves of FIGS. 1a and 1b, but the valves shown can also be used in the other devices described below, with a few structural modifications, in particular at the end of the suction valve and at the piston of the discharge valve.

In Figures 20a and 20b, the designation numbers are those of the parts bearing the same numbers in Figures la and lb. We see the two respective springs, designated by 24r, 74r, and 28r, 78r, relative to their respective ball.

FIGS. 21a and 21b show respectively an alternative discharge valve 128 and a suction valve 121. These valves can be used, within the scope of the claims, by replacing the corresponding ball valves, either individually or jointly, giving rise to four variants of metering pumps.

The valves of Figures 21a and 21b contain a piston having a piston head 124t and a piston base 124c, said piston being slidably housed in a housing having a head compartment and a base compartment. In the closed position, the piston head 124t conforms to the wall of its compartment in a sealed manner, and the piston cap 124c conforms to the wall of its compartment part in a sealed manner. In the wall of the two compartment parts are arranged at least one respective clearance 125,126. The piston is held in the sealed closure position by a spring 128 which is supported on a retaining rim arranged in the head compartment and which is pressed on the piston head. In this closed position, the lower part of the piston head rests on a closing surface 122, and the peripheral surface of the piston head 124t is in contact, at least partially, in sealed closure with the wall of the compartment to valve head. When a liquid pressure is exerted on the lower part of the piston in the case of the discharge valve, or when a vacuum is exerted on the upper part of the piston in the case of the suction valve, the piston goes back to his home. Then, the sealing on the support surface is canceled and the liquid rises through the clearances 126 in the lower part of the head compartment. At the same time, the reassembled piston head 124t is no longer in sealing contact with the wall of its compartment, and the liquid rises through the clearances 125 in the upper part of the head compartment, then in the duct overhanging said compartment. and born at location 123.

It is obvious that modifications known in the art can be made to this type of piston valve, p. ex. will it be possible to use a retaining spring rather than a support spring.

Figures 20a, 20b and 21a, 21b provide more details known in the art regarding the design of the component parts of the valves and allowing easy assembly thereof.

The suction valve 25e plunges into the maintenance liquid for contact lenses located in a bottle 14, and the discharge valve 21 is connected to the supply duct 5 secured to the cover 2. The pump contains a pump body 16 in which is placed a movable piston 18 sealed with the wall of the pump body 16, and held in the pump expansion position by a spring 20. The piston 18 communicates with the supply duct 5 secured to the cover 2, It can be seen that the assembly between the piston 18, the discharge valve 21, the supply pipe 5 and the cover 2 is rigid, so that, when the cover 2 is pressed, the piston 18 sinks into the pump body 16 by compressing the spring 20. The pump body 16 being filled with liquid, in normal operation, the latter lifts the ball 24 from its sealed lower seat and pushes it against its permeable upper seat. In this way, the liquid rises in the supply pipe 5 by compression of the interior volume of the pump body 16, and in the rotational position of the supply pipe 5 and therefore of the cover 2 shown in FIG. 1, the liquid does not finds another way out than the external debiting or sprinkling device 6,4,7. When the pressure is released on the cover 2, the spring 20 causes the piston 18 to rise in the pump body 16, expanding the volume of the pump. The vacuum thus created in the pump body 16 brings the ball 24 of the discharge valve 21 back into its sealed lower seat and therefore closes the said discharge valve 21. At the same time, the vacuum dislodges the ball 28 from the suction valve 25 from its sealed lower seat and brings it up against its permeable upper seat, thus opening said suction valve 25. This is how the piston 18, going up in the pump body 16 sucks the liquid contained in the device. bottle 14 in the pump body 16. As soon as the piston 18 reaches the end of the expansion stroke imposed by the stopper 19 which forms the partition of the pump 16 and serves as a sliding bearing for the supply pipe 5 which acts as a rod or arm to the piston 18, the suction valve 25 closes and the pump body thus remains filled with liquid, ready for a new delivery operation.

In the embodiment of the invention shown, the pump 16 is disposed vertically and essentially inside the bottle 14 and is held by its peripheral rim 17 located in the vicinity of the cover-stop 18 on the neck of the bottle 14 double-walled by means of a cap 11 fixed to the bottle 14 by means of a conventional fixing means, such as no screw, bayonet system, clip system, or another system.

The cap 11 is provided with a sniffing hole 10a which is nothing other than an enlarged passage accommodating another part.

The rod or arm formed by the supply pipe 5 connected to the piston 18 is guided on the one hand by the sliding bearing arranged in the central region of the partition cover 19 of the pump 15 serving as a stop for the piston 18, and guided on the other hand by a set of guide fingers 12a, 12b, 12c emerging from the cap 11, of which they are integral and arranged around the pipe 5 in sliding contact. A respective housing 32a, 32b, 32c is arranged in the body 1 of the lens holder and arranged to receive said guide fingers 12a, 12b, 12c, when the lens holder is lowered in order to fully depress the piston 18 of the pump 15 in the pump body 16. These housings 32a, 32b, 32c are indicated in the figures by dashed lines. They are used to save the space between the lens holder and the bottle, as well as a reception trough 34 arranged in the cap 11 and arranged to house the spray duct 4 carried by the body 1 of the lens holder.

In order to prevent any rotation of the body 1 of the lens holder relative to the bottle 14, or at least to limit its rotation to a negligible rate, at least one, preferably three protrusions 9a, 9b, 9c emerge from the bottom of the body 1 of the lens holder of which they are integral and penetrate into a respective lumen or passage 10a, 10b, 10c essentially matching the shape of the protrusions 9a, 9b, 9c and receive them in sliding contact. The tolerances between said protrusions and said passages accommodating them are sufficient to allow the passage of air or, as in FIG. 1, one of the passages, for example 10a, is slightly elongated in the radial direction with respect to the thickness of the protuberance 9a which it receives.

The partition cover 19 of the pump 15 is provided with lights or passages 31a, 31b, 31c arranged below the passages 10a, 10b, 10c and designed so as to allow the protrusions 9a, 9b, 9c of the body 1 of the holder lenses to penetrate into the body 16 of the pump 15 when the lens holder is lowered so as to push the piston 18 of the pump 15 fully into the body of the pump 16. The dimensions of these passages 31a, 31b, 31c are such that any friction of said passages with the protuberances 9a, 9b, 9c is reduced to a minimum or nonexistent, and that in any case air can penetrate into the pump body 18.

The penetration of the protrusions 9a, 9b, 9c in the passages 10a, 10b, 10c in sliding contact causes sufficient immobilization of the body 1 of the lens holder relative to the bottle 14, and makes it possible to rotate the cover 2 relative to the body 1 of the lens holder while holding the bottle 14.

Those skilled in the art will have noticed that FIGS. 1a, 1b and Ibis represent the same lens holder with its bottle in the same service position in vertical section, except for the two balls and the two springs, the tube immersed in the bottle, which are drawn in full.

Figure Ibis is used to locate sections AA, BB and CC shown in Figures 2, 3 and 4 respectively, detailing some of the organs described above. In these sections, the visible organs are drawn in solid lines and certain in principle non-visible organs are indicated in dashed lines.

Thus in FIG. 2 showing the section AA, there is shown a view “from below” of the lens holder of FIG. 1. There is distinguished there the pipe with central supply duct 5 and the set of protrusions 9a, 9b, 9c, the first and the last being integral with the body 1 of the lens holder. We also see the receiving housings (cavities) 32a, 32b, 32c arranged in the body 1 of the lens holder and serving to receive the guide fingers 12a, 12b, 12c emerging from the cap 11. In addition, we see the conduit nozzle or debitage 4. At the inner end thereof, Γ debit or nozzle 6 of the supply pipe 5 is indicated in dotted lines, and at the outer end of said nozzle 4, the directional orifice 7 arranged in the cylindrical envelope of the cover 2 is indicated in dashed lines. At the periphery, we see the three guide pins 33a, 33b, 33c used to hold the cover 2 in rotary sliding stowage on the lens holder 1. In the position of uncovering of the cups la, lb shown in section AA, the guide pins 33a, 33b, 33c are temporarily retained by the respective clips 34a, 34b, 34c. The other two triplets of clips corresponding respectively to the semi-uncovering and closing positions of the cups 1a, 1b are also visible.

In Figure 3 showing the section BB, we see the peripheral edge of the bottle 14 and the peripheral edge of the cap 11. We see the central supply pipe 5 and the three guide fingers 12a, 12b, 12c, the first and the last being integral with the cap 11, the guide fingers 12a, 12b, 12c serving as a rotation bearing for the pipe 5 and maintaining the latter in a vertical position. We also see the protrusions 9a, 9b, 9c emerging from the lower part of the body of the lens holder 1. We also see the trough 34 arranged in the cap 11 and used to accommodate the spray duct 4 in the compression position of the pump 15.

In FIG. 3 showing the section CC, we see the external spraying duct 4 carried by the lower part of the body 1 of the lens holder overhung by its cover 2.

FIG. 5 represents the device for the metering and cup closure lens holder in the filling or feeding position of the cups 1a, 1b. This position can also be used to place the previously cleaned lenses in the cups 1a, 1b, but these are advantageously placed in said cups in the position described above, and in particular after the external spraying operation used to clean and rinse the lenses.

In order to bring the device from its external spray position shown in FIG. 1 to the filling position shown in FIG. 5, the operator turns the cover 2 an eighth of a turn in the desired direction, and possibly in particular by so as to engage the guide pins 33a, 33b, 33c in the appropriate transient retaining clips 34a ', 34b', 34c '. During this rotation, the cover 2 rotates around the central pipe 5 of which it is integral, said pipe 5 being held by the rotation bearings described above and consisting on the one hand of the guide fingers 12a, 12b, 12c, and the central passage of the bulkhead cap 19 of the pump 15, on the other hand.

In the filling position of the cups 1a, 1b shown in FIG. 5, the spraying orifice 6 is no longer in communication with the spraying duct 4, but it is closed by the wall of the central passage of the body 1 of the door -lenses, in which the central passage is housed the supply duct pipe 5 in sealed rotary sliding, the sealing being interrupted only when the spray opening 6 is located opposite the spray duct 4, situation shown in Figure 1. By cons, in the position shown in Figure 5, the supply conduit device 8 of the cups la, lb is in communication with the filling device 3a, 3b of the cups la, lb. In particular the conduit 8a branching from the central supply pipe 5 is in communication with the filling duct 3a supplying the cup 1a, and the duct 8b branching from the central supply pipe 5 is in communication with the filling duct 3b supplying the cup lb. So that, when the pump 15 is actuated, the liquid discharged into the supply duct 5 has no other choice than to pass into the supply device 8a, 8b, then into the filling device 3a, 3b, to finally be poured into the cups 1a, 1b. Advantageously, the quantity of liquid pumped by a single compression of the piston 18 in the pump 15 is the quantity required to fill the two cups 1a, 1b at the desired level. The filling conduits 3a, 3b are located above the level of the liquid, so as to avoid contamination of the conduits 3a, 3b during the soaking of the lenses in the liquid.

In the filling position shown in FIG. 5, the cups 1a, 1b are, depending on the point of view, partially uncovered or partially closed by the cover, the openings 2a, 2b of the cover 2 being partially offset with respect to the cups 1a, lb of the body of the lens holder 1. In FIG. 5, it can be seen that the conduits 3a, 8a, 3b, 8b are partially arranged in the body 1, and partially in the cover 2 of the lens holder. We also envisage embodiments in which said conduits are arranged exclusively, either in the body 1 or in the cover 2 of the lens holder.

FIG. 6 shows the device of the metering lens holder and with cup closure in the lens storage or soaking position. In order to bring the device from its filling position shown in FIG. 5 to the conservation position shown in FIG. 6, the operator turns the cover 2 by another eighth of a turn in the same direction as before, and possibly in particular so as to engage the guide pins 33a, 33b, 33c in the transient retaining clips 34a ”, 34b”, 34c ”. During this rotation, the cover 2 turns again around the central pipe 5 of which it is integral.

In the conservation position shown in FIG. 6, the spray orifice 6 is always closed by the wall of the central passage of the body 1 of the lens holder, and moreover, the supply duct device 8a, 8b is also closed, in particular partially by said wall and partially by the head surface of the lens holder. All the orifices of the central supply duct 5 are therefore closed, except the discharge orifice 21 communicating with the pump 15. However in this position it is impossible to actuate the pump, since the compressed liquid does not find an outlet . The lens holder 1,2 cannot therefore be lowered in the direction of the bottle 14, and therefore it is blocked. For added safety, an optional mechanical pump blocking system is provided, the effect of which is added to the hydraulic blocking. This system is shown exclusively in Figure 6 in the small dashed circle. H contains a stud 131 emerging from the bottle 14 at a suitable location and a cooperating stud 130 emerging from the cover 2 at a suitable location and overhanging the first stud by touching it in the storage position of the lens holder with the cover secured. When trying to compress the pump, the nipple on the cover presses against the nipple on the bottle and thus prevents the lens holder from lowering. In the conservation position shown in FIG. 6, the cups 1a, 1b are completely closed by a sealing surface of the cover 2, and this in a hermetic manner, either by direct pressure of the cover 2 on the lens holder, or by indirect pressure of the same organs by means of suitable seals judiciously placed according to the art of the trade. Figures 7, 8 and 9 show the three useful service positions of the lens holder of the respective figures 1,5 and 6 and show at the bottom of the page the upper part of the lens holder and in the middle of the page a corresponding plan view. These figures are intended to show the play between the cups 1a, 1b and the openings 2a, 2b, on the one hand, and the play of the spraying device 6,4, 7 and the play of the supply and filling device 8a. , 3a, 8b, 3b on the other hand.

Figure 10 shows the head of the lens holder of Figure 8 to indicate sections AA and BB, the first passing through the clearance of the supply and filling conduits 8a, 3a, 8b, 3b, shown in solid lines in FIG. 10a, and the second passing through the play of the spraying device 6,4,7 shown in dashed lines in FIG. 10a.

Figures 1 to 10, and in particular 7,8,9 and 10 only serve to explain the configuration and the operation of an embodiment of the invention, without taking into account the relative dimensions of the members relative to the others and dimensions to be chosen for one or other practical embodiment of the invention. Thus, for example, FIG. 10a represents only a diagram of positioning of the various conduits and orifices for the sole purpose of clarification, and the various dimensions are exaggerated and also unrelated to those of the head of the lens holder showing the locations of cuts.

Referring now to Figures 7,8 and 9, we see the cups 1a, 1b of the body of the lens holder 1, and the lights 2a, 2b of the movable cover 2. We see, indicated in dotted lines since invisible in reality in view in plan, the supply and filling device 3a, 8a, 3b, 8b and the central supply duct S. We also see in dashed lines the spray device containing the spray hole 6, the spray pipe 4 and the directional orifice 7. Finally, we can also see in dashed lines the guide pins 33a, 33b, 33c which can serve as a reference for following the rotation of the cover 2.

The elements drawn in continuous line are located essentially in the upper plane, while the elements drawn in dotted line are located at different underlying levels which will be noted in the sectional drawing of the head of the lens holder. The marks 2c ’, 2c”, 2d, le and ld are used to identify the respective edges of the elements of the cover 2 and of the lens holder body 1.

The position of the cover 2 relative to the body of the lens holder 1 shown in Figure 7 shows the cups la, lb uncovered by the superposition of the lights 2a, 2b of the cover 2 and said cups. The supply device 8a, 8b for the cups is closed, while the external spraying device is open, by virtue of the alignment of the spraying orifice 6, of the spraying duct 4 and of the directional orifice 7. This position for uncovering the cups 1a, 1b and external spraying is used to empty the lens holder, when it has been used previously, and it is used to spray maintenance liquid on the lenses placed in the palm of the hand or held between thumb and forefinger. It can also be used to replace the lenses thus cleaned in the respective cups.

By turning the cover 2 relative to the lens holder 1 by an eighth of a turn anticlockwise, we arrive at the next useful position, that of FIG. 8.

The position of the cover 2 relative to the lens holder body 1 shown in FIG. 8 shows the cups 1a, 1b in semi-uncovering or semi-sealing, thanks to the offset of the lights 2a, 2b of the cover 2 relative to the cups 1a, lb of the lens holder body 1.

The external spraying device is now closed, thanks to the closure of the spraying orifice 6 arranged in the central supply duct 5 by the wall of the central passage arranged in the lens holder body 1 in which the duct is housed central 5. On the other hand, the supply and filling device 8a, 3a, 8b, 3b of the cups 1a, 1b is open, by virtue of the alignment of the respective conduits 8a with 3a and 8b with 3b. This filling position can be used to place the cleaned lenses in the respective cups, but it is primarily used to fill the cups la, lb of maintenance liquid for the preservation soaking of the lenses. By turning the cover 2 relative to the lens holder 1 by another eighth of a turn in the same direction as before, we arrive at the next useful position, that of FIG. 9.

The position of the cover 2 relative to that of the lens holder 1 shown in FIG. 9 shows the cups la, lb in obturation or closure, thanks to the superimposition of a closed continuous surface of the cover with the cups la, lb. The external spraying device is always closed, and in addition, the supply and filling device is closed, by closing the supply conduits 8a, 8b by the lens holder body 1. This closing position , both of the cups 1a, 1b and of the delivery ducts 6 and 8a, 8b of the supply duct, serve to keep the lenses in the soaking solution in the wells 1a, 1b hermetically closed, and to preserve the liquid contained in the various service conduits. After soaking the lenses for a sufficiently long period of time, the cover 2 is turned a quarter of a turn in the opposite direction to that used previously, and we find ourselves in the position of uncovering of the cups 1a, 1b, making it possible to remove the lenses to wear them again, and allowing the cups to drain the used soaking liquid.

Figure 10 shows the head of the lens holder of Figure 8 indicating the sections AA, BB and CC, the first passing through the clearance of the supply and filling conduits 8a, 3a, 8b, 3b, shown in solid lines in FIG. 10a, and the second passing through the play of the spraying device 6,4,7 shown in dashed lines in FIG. 10a.

FIG. 10a shows the positioning diagrams of the various conduits and orifices of the embodiment of the invention described above, and in particular, from left to right, the emptying / spraying position (vg), the filling position (r.) and the conservation position (c.). The cups 1a, 1b (not shown) are located in the extension of the conduits 3a, 3b, and the cup lights 2a, 2b, (not shown), are symbolized by small circles.

Based on this information, we can follow the respective positioning of the device for feeding or filling the wells 3a, 8a, 3b, 8b and the external spraying device 6,4, (7). In the v.g. position, only the spray opening 6 is open and communicates with the spray duct 4, while the filling ducts 8a, 8b are closed. By turning the cover 45 ° in the direction of the arrow, we arrive at position r., In which the spray orifice 6 is closed, while the filling conduits 8a, 8b are in communication with 3a, 3b respectively . By turning the cover 45 ° in the same direction, we arrive at position c., In which all the orifices and conduits are closed. By turning the cover 90 ° in the opposite direction, you arrive at the starting position, i.e. the v.g position. We have realized that the lens holder head in Figure 10 showing the position of the sections corresponds to the r position. of the sequence shown in Figure 10a.

FIG. 10b shows the positioning diagrams of the various conduits and orifices of another embodiment of the invention, which differs from the previous one, in that the spray conduit 6 is turned at an angle of 45 ° by relative to the supply conduits 3a, 3b (on the left, “skew”). The three positions (v.g.), (r.), (C.) Have similar functions and organs corresponding to the other embodiment, hence the use of the same reference numbers, but indicated in parentheses. What further differentiates the two systems is the rotational movements that must be printed on the cover covering the lens holder to bring it into the three service positions.

It will have been noted that the two embodiments of the invention corresponding to the positioning diagrams of FIGS. 10a and 10b involve a great saving in rotation gestures, in particular by the fact that one of the positions makes it possible to fulfill two functions: emptying of the cups and the external spraying of liquid: Other embodiments of the invention use positioning diagrams containing only two service positions, in particular a draining / spraying position and a filling / storage position. In the first position, the cups are essentially uncovered, and in the second position, the cups are essentially closed, which amounts to eliminating the intermediate position encountered in the previous embodiments. The invention provides an optional pump blocking system, in the case of modes combining the filling and storage functions in a single position. This blocking system can be a blocking ring sliding on the bottle when it is driven by the cover of the lowering lens holder, and remaining in the blocking position when it is brought into a precise position for hooking with afferent members. . This type of blockage is known to the art concerned.

Other embodiments of the invention use positioning diagrams containing four distinct positions, in particular one position for each operation: emptying (v.), Spraying (g.), Filling (r.) And conservation (c .). Such a diagram is shown in Figure 11 which shows that the lens holder cover must be rotated 45 ° in the direction indicated to move from the emptying position to the spray position, then 90 ° in the opposite direction to go to the filling position, then 45 ° in the same direction to go to the conservation position, and 90 ° in the initial direction to go back to the emptying position. The invention envisages other sets of positions and functions that one can easily imagine by building on the previous ones.

Another aspect of the invention is shown in Figure 12, which shows a lens holder 35 topped with its movable cover 36, the assembly having the distinction of having a rounded head, but having the organs and functions of the embodiments considered. The rounded head model is perceived as particularly aesthetic.

In order to increase the hygiene of the lens holders of the invention, it is envisaged to provide the respective cups with removable, frequently replaced linings. These linings can be for single use and are therefore discarded after their use limited in time, and in this case they are preferably made of polymer material. Otherwise, they are for extended use, but sterilizable by immersing them in boiling water for the required amount of time. As a material, polymers, metals, rubbers and the like are contemplated.

These linings can essentially match the shape of the receiving cups, as is the case in FIG. 13, showing the lining 38 conforming to the cup of the lens holder 37. These linings can essentially only fit part of the cups reception, as is the case in FIG. 14, showing the lining 40 resting on the wall of the cup of the lens holder 39.

In FIG. 13 as well as in FIG. 14, the linings are provided with a clearance 38a; 40a respective coinciding with the supply conduit opening on the corresponding cup. A lining orientation system is provided in its cup, eg enclosing a groove receiving a corresponding bead, one of the members being provided by the cup and the corresponding member being provided by the lining, so that that clearance 38a; 40a respective is necessarily present at the orifice of the supply duct of the respective lined cup.

The invention also contemplates an open cup bottom through a passage, eg 41 in FIG. 14, making it possible to eject the corresponding lining by the bottom of its cup, the lining being of course of the flexible type , eg made of plastic polymer.

In the foregoing, a metering and cup closure lens holder device stowed to a closed bottle, and a bottle with associated lens holder thus stowed, has been described, and various embodiments of the invention have been detailed. This invention requires the assembly and securing of the entire device in a sterile manufacturing environment, since the suction / discharge pump, with its suction hose, is immersed in the maintenance liquid and is in direct contact with it. During manufacture, the bottle is filled with liquid to a level such that by immersing the pump, the bottle is essentially completely filled, then the cap is secured to the bottle.

When the bottle is empty, following repeated maintenance of contact lenses, the user is obliged to discard the assembly and buy a new bottle with incorporated pump and stowed lens holder.

In order to avoid wastage of raw material and with the aim of reducing production costs, a second invention provides a metering and cup-closing lens holder device which can be attached to a bottle and a bottle for securing to the organs of reception, allowing to separately store a bottle filled with sterile cleaning product and having coupling or connection members and a lens holder device with integral pump, said bottle and said device having to be assembled before the first use by the wearer of lenses. Figures 15a and 15b show such a ready-to-use assembly, Figure 15a especially indexing the elements of the lens holder and its supply and spray orifices, and Figure 15b especially indexing the elements of the suction pump / repression, the two figures representing an identical copy of the same configuration.

FIGS. 15a and 15b, which are therefore identical, represent a lens-carrying body 51 capped with its cover 52. The lens-carrying body is provided with cups 51a, 51b and the cover 52 is provided with access lights 52a, 52b . The cover 52 is integral with a central pipe with a supply duct 55, the upper part of which branches into two supply ducts 58a, 58b which can communicate with a supply device 53a, 53b of the cups 51a, 51b. The lens-carrying body 51 carries a spraying duct 54 which can communicate by its internal end with a spraying orifice 56 arranged in the central duct 55, and which can communicate by its external end with a directional orifice 57 fitted in the peripheral cylinder of the cover 52. A set of pins 83a, 83b, 83c emerging from the cover 52 and sliding under the lens holder body 51 in contact with the latter makes it possible to maintain the cover 52 on the lens holder and makes it possible to guide the rotation of the cover 52 , and a set of clips 84a, 84b, 84c; 84a ’, 84b’, 84c ’; 84a ”, 84b”, 84c ”makes it possible to temporarily hold the cover 52 in different useful positions.

The cover 52 is provided at its lower part with at least one, preferably three protrusions 59a, 59b, 59c which can penetrate into corresponding openings 60a, 60b, 60c arranged in the head partition 66c of the pump 66 and dimensioned so reducing the rotation of the lens holder body 51 relative to said partition 66c at a negligible rate, said partition 66c being stationary relative to the bottle 64 in the assembly situation.

The central pipe with supply conduit 55 is connected by its lower end to an intermittent supply valve 71, which is connected to a piston 78 which can slide in the body 66 of the pump 65 and being held in its expansion position of the pump 65 by means of a spring 70, position in which the piston 78 is stopped by a partition-stop 69. This partition-stop is provided in its central part with a bearing in which the central pipe 55 slides, the latter being on the other hand held in vertical position by three guide fingers 62a, 62b, 62c secured to the head bulkhead 66c of the pump 65 and constituting another bearing for the central pipe 55. To the guide fingers 62a, 62b, 62c integral with the head partition 66c of the pump 65 correspond to respective cavities 82a, 82b, 82c arranged in the lens holder body 51. On the other hand, a trough 84 is arranged in said head partition 66c and corresponds to the conduit spray nozzle 54 carried by the lens holder body 51. Both the cavities 82a, 82b, 82c and the trough 84 make it possible to reduce the space required between the lens holder body 51 and the head partition 66c for the complete lowering of the piston 68. During this lowering, the protrusions 59a, 59b, 59c penetrate into the body 66 of the pump 65 by the corresponding slots 81a, 81b, 81c arranged in the partition-stop 69 of the pump 65. One of said lights, eg 81a, is slightly enlarged allowing ambient air to enter the body 66 of the pump 65, this air also entering through a light, eg 60a, slightly enlarged arranged in the head partition 66c fixed to the pump 66 in a conventional manner.

The body 66 of the pump 65 communicates at its lower end with a suction valve 75, which is provided with an external connection extension 85 having an internal reception passage 85bis whose diameter is greater than that of the end upper breakthrough 93 entering said reception passage 85bis and being the upper extension of the suction pipe 79 emerging from the double-walled bottle 64.

The suction end of the suction pipe 79 plunges permanently into the liquid to be pumped enclosed by the bottle 64. In the embodiment of the invention shown in FIGS. 15 to 19, the bottle is double-walled, the inner wall of which contains a deformable pocket 29 bis filled with the liquid to be dispensed. This pocket is subjected to the effect of an external force, in particular for example to the effect of atmospheric pressure, since it communicates with the ambient air by means of at least one sniffer hole 80a, 80b, 80c , in particular whenever liquid is delivered through the deformable pocket 29 bis. The external wall 64 of the bottle device serves to reinforce the construction, and the edge of the deformable pocket 29 bis is taken between the upper edge of the neck of the bottle and the edge of the receptacle 87, the securing and sealing of the volume inside of the deformable pocket 29 bis being ensured by the tightening of the receptacle 87 on the bottle. Tradespeople note that this is only an example of a fastener and that other judicious means of assembly exist. The rim of the sandwiched pocket 29 bis is preferably reinforced but flexible, so as to adapt to the surfaces which hold it to seal the otherwise deformable pocket 29 bis.

One of the other assemblies is shown in FIG. 32. It can be seen there that the deformable pocket is attached by its reinforced neck to the body of the receptacle 87. To make this assembly, a deformable pocket is made, preferably having a reinforced neck of slightly inner diameter. smaller than the outside diameter of the body of the receptacle 87, and the latter is threaded into the neck of the pocket 29 bis by forcing. In this way it is possible to seal said pocket. Otherwise, incidentally or alternatively, the neck of the pocket 29a can be thermally or chemically bonded to the body of the receptacle 87.

The intermittent discharge and suction valves each have a sealed seat inlet 72; 77 and a permeable outlet port 73; 76, as well as a ball 74; 78, the diameter of which is less than that of the corresponding valve housing 71; 75 in which the ball is movable. The balls 74; 78 are held in their respective closing seats by a respective spring 74r; 78r. At least one of the valves can advantageously be replaced by a piston valve, such as those of FIGS. 21a and 21b.

The pump 65 is held on the bottle 64 by means of a cap 61 establishing the link between them.

The essential elements and the operation of the lens-carrying device associated with its pump described above are analogous or identical to those of the invention described in FIGS. 1-14, and the detailed description corresponding to these figures is applied to the invention described in Figures 15-19 and is incorporated therein by reference. In fact, most of the similar elements carry parallel reference numerals which are differentiated by the value 50 which we subtract or add to move from one invention to another.

Still referring to FIGS. 15a and 15b, it is noted that the bottle 64 is closed by a cap 61 fixed to the bottle by a conventional screw pitch 101, but which can be replaced by any other known fixing means. The special shape of the cap 61 is also noted, in particular that it is of concave shape forming a receptacle 87 oriented towards the inside of the bottle and in which the body 66 of the pump 65 is housed. The presence of a ring 88 of particular shape housed between the pump body 66 and the bottom of the receptacle 87 of the cap 61. All of these elements form part of a coupling device between the pump 65 secured to the lens holder body 51 and the bottle 64 to concave reception cap 61. This coupling device makes it possible to assemble the lens holder 51/52 to the bottle 64 before the assembly is put into service for the maintenance of contact lenses. The constituent parts and the operation of the coupling device are described in detail using FIGS. 16, 17 and 18. FIG. 16 shows the two coupling parts before they meet, FIG. 17 describes the two parts in the pre-assembly position, and FIG. 18 shows the two parts in the coupling position, therefore of service.

Referring to FIG. 16, we can see the upper part of the bottle 64 to which the cap 61 is fixed thanks to the fixing 101. The cap 61 contains a concave receptacle oriented towards the inside of the bottle 64 and having a sheath extension 90. At the upper part of the receptacle 87, advantageously in the vicinity of the annular rim of the cap 61 is an inner ring 88, which in turn has a concave shape enclosing a reception sheath 86 oriented towards the interior of the receptacle 87. At least one stud 96a, 96b, 96c arranged on the peripheral surface of the inner ring 88 is engaged in a corresponding clearance located at the upper part of the receptacle 87. The studs 96a, 96b, 96c serve to hold the ring interior 88 in place.

The bottom 92a of the reception sheath 86 of the ring 88 contains a passage 92 in which is housed the upper end 93 of a pipe 79 communicating with the double-walled bottle 64 (the complete pipe is shown in full and not in section). The upper end, or head of the pipe is provided with at least one hole, preferably a set of holes 94 arranged in circumference at the head 93 of the pipe, the arrangement and the height of the holes being such that the holes 94 are completely closed by the wall of the passage 92 in this position. The pipe 97 is provided with a support flange 95 below the holes 94. The sheath 90 of the receptacle 87 of the cap 61 is provided with a pipe passage 89 which is crossed by the pipe 79, and the bottom of the sheath 90 contains a support housing 91 in the vicinity of the passage to pipe 89, which housing is intended to receive the flange 95 of the pipe 79. It should be noted that the distance between the lower surface of the flange 95 and its surface d 'corresponding support of the support housing 91 is less than the distance between the lower surface of the ring 88 and its support surface of the bottom of the receptacle 87. It follows that, when the ring 88 is pressed into the receptacle 87, the ring initially drives the pipe 79 in its descent, since it has been ensured that the friction in the pipe passage 89 is less than the friction in the passage 92 holding the pipe head 93 .

In a second step, the support flange 95 touches its support surface 91, and the ring 88 continuing to sink into the receptacle 87, the pipe head 93 rises in the reception sheath 86 of the inner ring 88.

The dimensions of the members concerned are chosen so that the holes 94 arranged in the pipe head 93 are uncovered at least partially, and preferably entirely, following the penetration of the pipe head 93 into the reception sheath 86 taking place when the ring 88 touches its bearing surface of the bottom of the receptacle 87 or approaches it sufficiently.

Another embodiment provides that the lower surface of the annular part of the inner ring 88 does not touch the corresponding surface of the bottom of the receptacle 87, which is more elongated in this case, but rests on one or more flanges provided to the wall of the receptacle 87. In this case, the sheath 86 is also elongated, in particular to the same extent. Another embodiment provides that the sheath 86 is not elongated, but that, on the other hand, the bearing surface 91 for the bearing rim 95 of the pipe 79 is raised rather than being set back, in particular in the measurement of the extension of the receptacle 87.

Another embodiment provides that the support housing 91 receives only the lower part of the rim 95, and that the upper part is housed in an adequate clearance in the lower surface of the bottom of the sheath 86. If such a clearance is not arranged, eg provision is made to extend the receptacle 87 accordingly.

Another embodiment does not provide any clearance for the rim 95 and provides for the extension of the receptacle accordingly.

Other variations in shape and size become apparent to tradespeople in light of previous observations.

The wall of the receptacle 87 contains in its lower part grooves 100a, 100b arranged so as to accommodate the projecting members of the inner ring 88, in particular the clip stud (s) 96a, 96b, 96c, 96d. These nipples can also be replaced by beads, in which case, said grooves are widened accordingly. The wall of the receptacle 87 also contains one or more studs or beads 99'a, 99'b, 99'c, arranged so as to clip and retain the ring 88 when the latter is pressed into the receptacle 87 at its level lowest operational. In the figures, the clip pins 99 ′ overhang the respective grooves 100, in order to be able to show these elements on the same drawing, but in practice provision is made to offset them relative to each other, in order to facilitate the engagement of the pins 96a, 96b, 96c in the corresponding grooves 100a, 100b, 100c.

Still referring to FIG. 16, we see, overhanging the closed bottle head, the pump 65 having a pump body 66 and the other pump members described in the foregoing, as well as the members for functional cooperation with the holder lenses 51, also already described in the foregoing. Note the clip pins 97, 98. We also note the connection extension 85 having inside a reception passage 85bis. Finally, note the particular shape of the lower edge 99 ”a of the pump body 66.

FIG. 17 represents the pump 65 in the pre-assembly or pre-coupling position. It can be seen that the connection extension 85 is threaded into the reception sheath 86 of the inner ring 88, the latter remaining in place. There is a tolerance between the connection extension 85 and the reception sheath 86 sufficient to evacuate the air during the advancement of the male part into the female part, and at the same time to ensure that the ring 88 remains in place during this operation. We can also see that the lower circumferential clearance 99 ”a of the pump body 66 follows the peripheral edge of the ring 88, and that the lower surface of the pump body rests on the annular part of said ring, which gives greater stability to the coupling of the pump 65 to the ring 66. This is an important aspect, but not essential.

It is also noted that the head of the pipe 93 remains housed essentially in the passage 92 from the bottom of the reception sheath 86.

FIG. 18 represents the pump 65 in the completed coupling position with the head of the bottle 64, which was achieved by driving the inner ring 88 using the pump 65 into the receptacle 87. During this operation, the clip pins 96a, 96b, 96c, (96d) are released from their respective housings and slide along the wall of the receptacle 87. This and other operations are made possible thanks to the flexibility of the material, the relevant parts of which are manufactured. When the sealing ring has reached the end of its travel, it is retained by clipping by the pins 99'a, 99'b, 99'c, 99'd and remains integral with the cap 61 of the bottle 64. However, before the ring 88 reaches the end of its travel, the rim 95 of the pipe 79 rests on its corresponding bearing surface 91 arranged in a small housing, and therefore the passage 92 slides along the pipe head 93, thus freeing the holes 94 which are found essentially in the reception passage 85bis of the connection extension 85 closed at its lower end by the reception sheath 86. It is noted that the wall of the reception passage 85bis is clear of holes 94.

In the foregoing, the connection members between the pump 65 and the closed cap head 61 of the bottle 64 have the cylindrical connection parts, but other embodiments envisage forms of non-revolution, eg elliptical, angled or other, particularly fancy. In particular, asymmetrical shapes are envisaged which impose a single possible coupling approach without resorting to guiding or orienting members. In the coupling position, the flange 67 of the pump body 66 is partially housed in a recess provided in the upper annular surface of the cap 61, which increases the stability of the configuration. The friction generated in this housing serves to slightly hold the pump 65 in the coupling position, and in this way, it can easily be released when the bottle 64 is empty and it is necessary to replace it with a full bottle. If necessary, provision is made for one or more light clips to hold the pump 65 more securely.

FIG. 19 represents another embodiment of the invention, which shares most of the characteristics and has the same operating principle as the previous embodiment. We therefore only describe the distinctive elements which differentiate it from the previous mode.

We see a cap attached to a bottle head and having a concave receptacle 107 oriented towards the inside of the bottle. An inner ring 105 is slidably supported on the inner surface of the upper part of the receptacle 107. This ring 105 has a central passage 106, into which the connection extension 103 of the pump 102 can be threaded.

The bottom of the receptacle 107 contains a reception sheath 108 designed to be able to accommodate the connection extension 103 of the pump 102, and the bottom of the reception sheath 108 contains a reception space in which the upper end is housed or head 110 of a pipe passing through the bottom of the reception sheath 108 and plunging into the bottle. The pipe head has at least one peripheral hole, preferably a plurality of peripheral holes 111. Between the interior surface of the receiving sheath 108 and the head 110 of the pipe is a sealing ring 112 closing off the holes 111 in the pipe head 110. The height of the pipe head 110, as well as the height and the location of the holes 111, and the height of the ring 112 are such that sufficient annular space remains under the ring 112, so that, when the ring is lowered by pushing it in, the holes 111 are essentially entirely or at least sufficiently clear to allow the rising liquid to pass through the pipe. The ring 112 is provided with a sniffing duct at a convenient location, so as to evacuate the underlying air when the ring 112. is pushed in. When the pump 102 is pushed fully into the receptacle 107, the lower end of the connection extension 103 having an internal passage 104, the diameter of which is greater than the diameter of the pipe head 110, pushes the ring 112 and releases the holes 111 from the pipe head 110. At the same time, the ring interior 105 is clipped at the end of its journey. The receiving receptacle is the extension of the pump body, and the assembly is called the final body.

In this embodiment, one or more guide or orientation members can also be provided between the pump 102 and the ring 105, and between the latter and the receptacle 107. Similarly, any other form of these members is provided. , in particular of non-revolution, eg elliptical, angled, or fancy, and in particular asymmetrical shapes which impose only one possible coupling approach without resorting to guiding or orienting members.

Typically, the lens holders according to the present invention are made of a rigid material, preferably a rigid polymer, the covers are also made of a rigid material, preferably of a rigid polymer, in particular of transparent acrylic polymer. , the auxiliary and connection parts are made of materials having rigidities and flexibilities adapted to their function, and the bottle is made of a flexible or rigid polymer material, compatible with the requirements of the stored liquids.

FIGS. 22 and 23 represent another embodiment of the invention, which constitutes an improvement of the embodiment shown in FIGS. 1a, 1b, 1c of part I. It can be seen in particular that the supply conduit 5a communicating with the discharge orifice 21 of the pump 15 is connected to the supply conduit 5b of the wells by means of reversible connecting members. Said connecting members contain a male member 5a ’and a female member 5b’ corresponding reception and adapted to the first. Said reversible connecting members can also close a system of clips 130, having at least one projection 130a and a corresponding reception clearance 130b. The clip system makes it possible to temporarily fix the reversible link.

When you want to separate the lens holder 1 from its dosing pump 15, simply pull on one of the parts while holding the other. When we want to join a lens holder 1 to a metering pump 15, we push the male organ 5a ’into the female organ 5b’ until the clip system is engaged. This is done by pressing the piston 18 of the pump on the bottom of the pump body 15. In passing, note the protrusion 9c lowering from the body 1 of the lens holder, in addition to the related protuberance 9a. The protrusion 9b cannot appear on these drawings. (In the figures in part I, the protrusion 9c is hidden by the supply duct).

FIGS. 24 and 25 represent another embodiment of the invention, which constitutes an improvement of the embodiment shown in FIGS. 15 to 19 of part I. It can be seen in particular that the supply duct 55a communicating with the discharge orifice 71 of the pump 65 is connected to the supply conduit 55b of the wells by means of reversible connecting members. Said connecting members contain a male member 55a ’and a female member 55b’ corresponding reception and adapted to the first. Said reversible connecting members can also close a system of clips 131, having at least one protuberance 131a and a corresponding reception clearance 131b. The clip system makes it possible to temporarily fix the reversible link.

When one wants to separate the lens holder 51 from its dosing pump 65, it suffices to pull on one of the parts while holding the other. When we want to join a lens holder 51 to a metering pump 65, we push the male member 55a "into the female member 55b" until engaging the clip system. This is done by pressing the piston 68 of the pump on the bottom of the pump body 65.

In passing, note the protrusion 59c lowering from the body 51 of the lens holder, in addition to the related protrusion 59a. The protuberance 59b cannot appear on these drawings. (In the figures in part I, the protuberance 59c is hidden by the supply duct.)

By varying the intensity of friction, and the intensity of the connection of the respective clip systems 131 and 96a, b, etc., it is possible to decide on the sequence of clipping and unclipping of the pump body 66 in the receptacle and the reversible link connecting the supply duct 55a to the supply duct 55b.

Regarding the manufacture of the various embodiments of the invention, both of part I and of part Π, it is obvious to those skilled in the art that the different parts can be made of the most diverse materials, limited only by the function of the various organs, the ease of implementation and the cost of the materials. Preferably, the parts are made of polymer materials, which are most often shaped by molding, by injection-blowing or by injection-molding, according to techniques known to those skilled in the art, among others.

On the other hand, it also appears obvious to those skilled in the art that it will be possible to delete certain organs from the various embodiments of the invention, without departing from the teachings of the claims and within the latitude thereof. Thus, we can remove the outer spray duct 4; 54 if you do not wish to use this function of the various devices. Who can do the most, can do the least, and those skilled in the art will know how to make the small changes made necessary by this renunciation without further ado, without departing from the lessons of the claims and within the latitude of these.

In the foregoing, the invention is described with respect to two types of essential embodiments, one of which provides a pre-assembled device, in particular in an assembly line, and the other of which provides a device to be assembled during implementation, in particular by the user himself. In these devices, a double-walled bottle is described, the inner wall of which contains a flexible and compressible pocket, the head region of the respective pockets being fixed to the head rim of the external wall, which is more rigid than the internal wall. (Said compressible inner pocket is represented by a simple line, given its mandatory thinness.)

We have seen that one of the important characteristics of the present invention is the interior volume of the compressible bottle as the liquid contained in the bottle is cut.

Double-walled bottle devices can be manufactured according to known methods, in particular by injection molding or by blow molding. FIG. 26 schematically shows the principle of a manufacturing process allowing the double-walled bottle to be produced using a combined tool. We see there a mold 132 in which the outer wall 133 of the bottle has already been formed, and in which a preform 134 of the inner wall to be formed has been introduced. The head rim 134t of the preform 134 is held by a jaw 135 which presses it against the rim of the outer wall 133, the latter being supported by the mold. A fluid, eg air, is injected into the preform until it more or less takes the shape of the outer wall, without however sticking to it.

We note the two points 136a, 136b, which pierced the outer wall 133, and which are removed during the blowing of the inner pocket 134.

Then, the inner pocket can be filled with lens maintenance liquid, either by the blowing channel 135c of the jaw 135 or by another channel thereof, or by removing the jaw 135 and injecting the liquid through a separate injector. The pump and bottle cover assembly, or the closed receptacle for subsequent coupling, can then be placed, depending on the type of embodiment of the invention. In delayed assembly models, it is also possible to fill the bottle after the coupling receptacle has been installed, then introduce the small suction pipe with the inner closing ring (see Figures 15 to 19 p. ex.).

Figures 27 and 28 show devices similar to the previous ones, but in addition, the bottom of the pockets 29 is provided with a small tip 137a which is taken in a hole 137b arranged in the bottom of the outer wall of the bottle. This has the advantage that the bottom of the bag 29 does not lift and does not obstruct the suction port of the pump, at the end of the emptying of the bottle. One could of course provide at least one lateral hole on the orifice tube to solve the same problem.

The manufacturing of this embodiment can be done essentially like that of FIG. 26, but in addition, the preform 138 has an end piece 139a which is introduced into the recess 139b of the bottle 140 and is retained there, eg by suction or pinching exerted by the mold 141 or an adjoining member. It will be ensured that the end piece 139a is slightly oversized with respect to the clearance 139b and that it is forced into it. One can also use thermal effects to weld the tip 139a to the clearance 139b. The clearing 139b of the external wall 140 of the bottle can be achieved using a mold tip 142 introduced during the molding of said wall, this mold tip then being removed partially or completely for the rest of the operations.

Such a mold tip may have a central brush and at least one other brush, the first serving to pierce the hole in the bottle intended to accommodate the stud of the inner pocket, and the other serving to pierce a sniffing hole, which is then located near or in the vicinity of said stud, after assembly of the device. This simplifies the construction of the mold. Alternatively, the brush may have the shape of a knife which pierces a slit in the bottom of the bottle, part of this slit will serve to receive and retain the nipple of the inner pocket, while another part of the slit will serve as a sniffer.

Figures 30 and 31 show an embodiment in which there is a double-walled bottle, the inner wall of which contains a flexible and compressible pocket 29, the head region of the respective pockets here being fixed, depending on the model, either to the body of the dosing pump, or to the coupling receptacle for a dosing pump. Figures 32 and 33 also show, relative to the previous two figures, respective pockets 29 provided with a respective retaining tip 143,144.

FIG. 34 schematically shows a method of manufacturing the double-walled bottles of FIGS. 30 and 31 which is similar to the preceding methods of manufacture, except that the preform 145 is held by a peripheral jaw 146 which holds it by suction, for example. After the inner wall 145 has been formed, the bottle is filled with lens maintenance liquid. After which, the dosing pump is forced, respectively the coupling receptacle in the neck 145a of the inner wall 145, while holding the latter by the jaw 146. Then said neck is lowered into the bottle by carrying out the topping-up operations. and immediately (stowage, filling, closing).

For the manufacture of the models of FIGS. 32 and 33, one will be inspired by the preceding manufacturing diagrams by combining the elements and opportune operations in judicious ways.

Figures 35, 36, 37 and 38 show embodiments having double-walled bottles, the inner wall of which encloses a pocket 147 fixed either to the lower part or to the upper part of the dosing pump, respectively of the coupling receptacle pump. Said pockets are drawn in full (not in section), as are the members to which they are fixed, from the horizontal line with the two small vertical arrows. The particularity of these respective pockets 147 lies in the fact that they are fixed in a first operation to their respective liquid suction member by judicious folding and by gluing of a flexible sheet, which can be a laminated sheet, p .excluding an outer layer of aluminum and an inner layer of polymer. At this point, the pocket is flattened and essentially empty of air.

The bag is then wrapped around its longitudinal axis, as shown in Figure 39a (at which the winding is not yet completed). Incidentally, some pockets 147 may be provided with a small filling tube 148, arranged eg at the bottom. The rolled-up pocket 147 is introduced into the wall of the outer bottle, and the pump and cap assembly, respectively the pump coupling receptacle, are assembled with the neck of the respective outer bottle. When the pocket has a filling tube 148, care will be taken to arrange a passage in the corresponding part of the external bottle, so that the filling tube 148 emerges from the external bottle after introduction from the pocket in it.

Figures 35 to 38 show the respective pockets 147 just after their introduction into their corresponding outer bottle. They are unrolled and always empty and flattened. In these figures, the short dotted lines indicate the parts of organs located in the respective pockets 147, and the more elongated dotted lines delimit the glued edge of the pockets and the portions of unglued interior walls.

The devices of Figures 37 and 38 are shown without a filling tube. They can be filled by passing the pump receiving receptacle before it is mounted. Obviously, provision can also be made for filling with a small bottom tube, as above.

Another filling method consists in bringing the balls of the suction and discharge valves of the metering pump into their open position, eg by means of an external magnet, provided that the balls are made of ferro-magnetic material. The bottle can then be filled through the supply lines of the cups, the cover of the lens holder being in the feeding position. This process can be applied to all models suitable for it.

When filling said pockets by introducing a fluid at a pressure higher than atmospheric pressure, the inner walls of the pockets move apart and the folded bottom lowers and spreads its outer edges, in order to create an interior volume for the respective pocket .

The devices of Figures 35 and 36 are filled by the small bottom tube, which is then sealed, after having been removed or cut if necessary.

FIG. 39b shows the flow of operations for creating a pocket 147 which can be used in the devices of FIGS. 35 to 38. A sheet 148 of a flexible material is cut, eg a sheet of aluminum / polymer laminate, and make a hole 150, then fold the sheet as shown. The peripheral regions 148b are coated with an adhesive (indicated by the dotted lines), marking an excursion towards the middle in the region of the folds. Then we apply the communication piece 149 of the dosing pump, and we introduce the filling tube 156 in the hole 150, until its edge 151 touches the sheet 148, and we press the press button 152 on the tube 156. Points 158 emerging from the press button 152 pierce the sheet and engage and clip into respective housings 161 located in the flange 151, so as to seal between the sheet and the tube 156. Finally, the two parts of the sheet are joined according to the arrows AA ', then the parts are carefully joined in the vicinity of the folds (arrows BB'). One thus constitutes a pocket 147 having an interior region 148a not bonded, but flattened and void of air. Instead of using an adhesive, you can also or incidentally perform a heat seal. We note the flattened shape of the communication piece 149, which can advantageously be elliptical or lozenge-shaped or have another shape deviating at least the two flaps of the sheet 148 in assembled arrangement.

Figure 39c shows the bag 147 after its manufacture. We see that the lower part of it has two fins 160a, 160b and a bottom folded inwards. When the bag is filled with a fluid, it expands and changes its configuration as shown in Figure 39d. Figures 39a, 39b, 39c show the filling tube only schematically.

Figure 39d shows a filling tube 156 in detail. It is seen there that the sheet 148 is sandwiched by the flange 151 and the press button 152. The points 158 emerging from the press button pass through the sheet 148 and are housed in the housings 161 of the flange 151 and they are clipped by the clips 159. The flange 151 is in fact a ring, the central passage of which accommodates a pipe head 153 having at least one lateral hole 154 overhanging the flange 151 and communicating with a conduit located inside the head and closed at its end superior by it.

Said inner conduit is extended by a hose 156 reversibly attached thereto, which hose is used to fill the bag 147. As soon as the filling is completed, the hose 156 is pulled, thus causing the hose head 153 in a sliding movement. , until the pins 155a engage in the receiving hollows 155b of clips. At the same time, the head 153 can rest on a ledge. By pulling more, the pipe is released from one or more clips 157 which connect it to the pipe head 153, and it is separated from said head. In this position of the head 153, the holes 154 are hidden by the interior wall of the sliding reception passage of the flange 151, and thus this communication channel of the pocket 147 with the outside is cut, and the pocket 147 is closed there.

Note on all the embodiments with a compressible inner pocket, the presence of at least one sniffer hole 30a, b; 80a, b.

The compressible pockets are made of a flexible and sufficiently thin material, in order to guarantee the deformability of the pockets. Polymers, eg polyethylene, polypropylene, etc., or laminates having at least two layers, one layer of which is made of polymer and the other of which is made of metal, eg aluminum , or laminates having two layers of polymers which are chemically and / or physically distinct.

Figures 40 and 41 show another embodiment of the compressible volume, usable in the devices of the invention. In these modes, a movable piston 162; 163 is arranged in the bottom of a respective bottle 14; 64 filled with liquid. The bottom wall of the bottom of the piston 14; 64 is in contact with atmospheric pressure, and consequently this causes the sliding piston 162 to rise; 163 when a respective pump takes liquid from the corresponding bottle 14; 64. In the drawings, the bottles 14; 64 have no equity, and the pistons 162; 163 have a configuration capable of essentially matching the metering pump, respectively the pump receiving receptacle, depending on the model, at the end of the piston stroke. The absence of a clean bottom and the particular configuration of the pistons are advantageous, but not essential, characteristics.

We can fill this type of device by the head, like some others, but we can also fill it from the bottom, before installing the respective piston. A suitable sniffer vents the air.

FIGS. 42 to 58 show other embodiments of devices and coupling mechanisms between a metering pump connected to a lens holder according to the invention and a corresponding reception receptacle connected to a bottle supplying maintenance solution for the lenses.

In FIGS. 42 to 48, the passage 166,168,170,172,174,176,178 of a respective bottle reception receptacle is closed by a corresponding hollow or full stopper 167,169,171, 173,175,177,179. By pushing the corresponding dosing pump into its receiving receptacle, the extension 180 (designated by the same number in all these figures) pushes the respective cap into the bottle and thus establishes flow communication between the pump and the bottle. To prevent the plug from possibly obstructing the pump duct, at least one additional orifice, in particular lateral 181a, b, c, etc., is provided on the extension of the pump. The cap can be of the simple type or have a rim, a clip or both. The rim is arranged so as to prevent pressure exerted by the liquid from pushing or ejecting it from the top of the reception passage. The clip can be located in the wall of the reception passage, or overhanging it. It is also used to resist excessive pressure exerted by the liquid in the bottles.

The plug shown in FIG. 48 has the particularity of having a head stud 182 capable of engaging in the conduit 183 of the extension 180 of the pump, while the latter is inserted into the passage of the receptacle. The stopper is retained there, and the liquid flows out through the lateral opening (s) 181a, b, c ... - When the pump is removed to replace the empty bottle with a full one, the stopper 179 is brought back into the initial reception passage and the bottle is closed, then the pump is released completely. In FIGS. 49 to 52, the respective passage 184,186,188,190 is closed by a corresponding cap 185,187,189, 191 positioned so as to resist excessive pressure exerted by the liquid in the bottle and to keep the bottle closed. Said caps can have different shapes, and in particular, they can have nipples or a bead of clips, or their rim can be housed in a groove located in the lower part of the receiving receptacle. When the pump extension 180 is pushed into the passage of the receptacle, the respective cap is dislodged and the flow communication is established as above. The extensions 180 can have essentially the same characteristics as the previous ones.

In Figures 53 and 54, passage 192; 194 of the pump reception receptacle is closed by a membrane 193; 195, which can be an independent or integral membrane of the receptacle bottom. It can be placed at various places, in particular between the places and at the places chosen in FIGS. 53 and 54.

The pump extensions 195 can be provided with at least one tooth 196 intended to rupture the respective membrane 193; 195 when the pump is fully inserted into its receptacle.

FIG. 55 represents another embodiment of the securing members according to the invention. It can be seen that a receptacle attached to a bottle has a conduit 196 with passage 196p located at the bottom of the receptacle. The passage 196p is provided with at least one bypass groove 196r. In the device pre-assembly position, both the main passage 196 and the groove 196r are obstructed by a piston stopper 197. When the dosing pump is pressed into the receptacle, the connection member 180 of the pump moves the piston 197 sufficient in the passage 196p towards the inside of the bottle so that at least the upper region of the groove 196r is released and placed in communication with a corresponding conduit 181b of the connection member 180 of the pump. Thus, the liquid pumped into the bottle can pass through the bypass groove (s) in the suction pipe of the pump.

FIG. 56 shows another embodiment of the securing members according to the invention. It can be seen that a receptacle attached to a bottle has a conduit 198 with passage 198p located at the bottom of the receptacle. The passage 198p contains at least one channel 198c having an inlet end and an outlet end for the liquid to be pumped. The outlet end of the channel 198c is blocked by a piston plug 199 in the device pre-assembly position. When the dosing pump is inserted into the receptacle, the connection member 180 of the pump displaces the piston 199 sufficiently in the passage 198p towards the inside of the bottle so that the upper region of the outlet end of the channel 198c is released and placed in communication with a corresponding conduit 181b of the connection member 180 of the pump. Thus, the liquid pumped into the bottle can pass through the channel (s) in the suction pipe of the pump.

FIG. 57 represents another embodiment of the securing members according to the invention. This embodiment is similar to that of FIG. 19, from which most of the reference figures have been used, and it amounts to removing the centering ring 105, modifying certain dimensions and removing the clips from the ring. centering.

FIG. 58 represents another embodiment of the securing members according to the invention. This embodiment is similar to that of FIG. 16, from which most of the reference figures have been used, and it amounts to removing the receptacle 86 from the ring 88, to removing the receptacle 90 from the bottom of the receptacle 87, repositioning the closure ring 88 and repositioning the pins 97.98 and the grooves or housings 96a, 96b for clipping the pump 66 to the receptacle 87. When the pump is pressed into the receptacle, the connecting member 85 of the pump first releases the ring 88 from its clipping, drives the ring into the bottom of the receptacle 87, and secondly when the flange 95 of the pipe 79 touches the bottom, the pipe 79 rises sufficiently by relative to the ring 88 to clear the orifices 94 which are then in hydraulic communication with the passage 85bis of the connection member 85. Thus, the liquid pumped into the bottle can pass through the orifice (s) 94 in the conduit d of the po mpe.

The last two embodiments have the advantage of eliminating a part, and therefore of reducing the cost price of the respective devices.

Figures 42 to 58 do not show certain elements, such as the compressible pocket 29bis, since they only serve to explain certain modes of securing usable in the devices according to the invention.

The transient fixing means, such as nipples, beads and cooperating members, are those known in the art in all their latitude. Tie-down bottles when first used can be closed or sealed with a suitable cap, eg an aluminum or laminate sheet fixed by heat-bonding, in order to guarantee the sterility of the contents of the bottle and its stowage member.

Note also that in the figures, many solid lines in fact present a multitude of small interruptions, and those skilled in the art are of course aware that these are imperfections due to the drawing made on a printer of poor quality. It is enough to move away enough from the figures so that these involuntary discontinuities seem to disappear, and we can thus contemplate the objects represented as a whole. Other lines, traced with the pen, are indeed continuous.

We also note that in Figures 42 to 58 some details are disregarded, in particular the inner bottle pocket, in order to simplify the figures. Tradespeople will be able to compose the various and numerous devices that are now apparent to them.

In all the embodiments, it is provided that the air is evacuated from the reception receptacle when the corresponding pump is inserted therein, in particular by virtue of a sufficient tolerance between the two members or by providing an evacuation groove, if necessary . This remark applies to all cases where the problem arises, the clips retaining the pumps in their respective receptacles can be engaged in individual clip clearances or in a receiving groove. Likewise, the clips may contain a bead engaged in a groove. This remark is valid for all the embodiments concerned.

Other embodiments can be designed on the basis of the teachings contained in the present description and falling within the latitude of the appended claims.

The invention also relates to a method and a method for maintaining contact lenses, according to which the light cover moving over a lens holder is moved in a movable manner between at least two useful positions. The first position essentially discovers a cup device, having at least one cup, coiled in the body of the lens holder, and the second position essentially closes said cup device. In addition, at at least an opportune moment, a pump, preferably a metering pump, is connected, connected to the lens holder on the one hand, and connected to a bottle filled with maintenance solution on the other hand, so as to treat the lenses. contact with a portion of said solution.

According to another embodiment of the method and of the method, the following operations are carried out essentially sequentially: - the light cover moving over a lens holder moves movably from a rest position to a first useful position, which discovers essentially a cup device having at least one, preferably two cups coiled in the body of the lens holder, - at least one lens is removed from said cup device, - one lens or both lenses are rinsed one by one or jointly after their removal of their respective wells, in case a rinse is indicated. Rinsing is generally indicated for the sake of hygiene, but also in the event of marked sensitivity of the eyes of the wearer of lenses, rinsing eliminating most of the soaking solution containing debris of soils and microorganisms killed or inhibited.

To perform this rinsing, an external jet of liquid is sprayed on each lens, and preferably a spray of maintenance solution is sprayed there, in particular by actuating a pump, preferably a dosing device, - the lens is worn on the corresponding eye. , or it is placed elsewhere, - the rinsing operations are repeated for the second lens, if necessary, - the used solution found in the wells is discarded; then it is recommended to rinse the wells under a jet of external liquid, p. ex. under tap water; each lens is cleaned, after having worn or handled it, especially if cleaning is indicated. Cleaning is generally recommended for the sake of increased hygiene, but especially in the event of fouling and contamination of the lenses, when the simple soaking of the lenses in the maintenance solution between two normal wearing periods cannot be completed. bothersome deposits on the lenses. To perform this cleaning, an external jet of liquid is squirted on each lens that is held stationary, p. ex. in the palm of the hand, and preferably a spray of maintenance solution is sprayed there, in particular by actuating a pump, preferably a metering device, then each lens is gently massaged with a finger, - each lens is rinsed, if indicated and in particular always when a cleaning has been carried out, by spraying an external jet of liquid on each lens, and preferably a jet of maintenance solution is sprayed there, in particular by actuating a pump, preferably dosing, - the lenses in the respective wells, - the cover is moved to a second useful position which essentially closes the wells, - the lenses placed in the wells of maintenance solution are immersed, by actuating the pump so as to fill the wells with solution, - the lenses are kept in this closed position of the lens holder, which corresponds to the initial rest position, - incidentally, the pump can be blocked by actuating a blocking device e, - we start the cycle again when we want to reuse the contact lenses.

According to another embodiment of the method and of the method, the light cover moving over a lens holder is moved in a mobile manner between three useful positions.
