Description

APPARATUS TO CONTAIN A COMPOSITION FOR DILENT CARE OF CONTACT AND TO HOLD A CASE FOR LENSES OF CONTACT BACKGROUND OF THE INVENTION The present invention relates to an apparatus that includes two removable containers or sections that are secured to one another. More particularly, the invention relates to such an apparatus in which the first container houses a material for its delivery, such as a composition for the care of contact lenses, and the second container defines a holding compartment, for example for holding a contact lens case in which the liquid composition can be used to treat contact lenses.

Contact lenses frequently require periodic treatment, for example, disinfection, cleaning, rinsing and others, to provide substantial operating advantages. Such treatments often take place by immersing the lenses in a composition for the care of contact lenses, for example, a solution in a case for contact lenses. Such cases can be used to store contact lenses between periods of use. When Ref.124465 it is desired to treat the lenses, the appropriate composition for contact lens care is removed from a bottle or container that includes the composition and which passes to the contact lens case in which the contact lenses have been placed. After the treatment, the contact lenses are ready to be placed in the user's eyes.

This relatively simple criterion for the care of contact lenses has certain disadvantages. For example, because the composition for the care of contact lenses and the case for contact lenses are separate components, one of these components may be lost or rendered useless. For example, in travel situations, the composition for the care of the lenses or the lens case can easily be lost or * or packaged. It would therefore be beneficial to provide a system in which the composition for lens care and the lens case will be stored together.

In the past, bottle systems for the composition for lens care and lens case have been suggested. For example, the bottles have been molded in such a way as to provide a space in which the lens case can be received. However, the cost of manufacturing for such combined systems has been relatively high. ^^^^^^^^^^^^^^^^^^^^^^^ g ^ g ^ ^^ ttak ^ M ^ £ ^^ g ^ M ^! ¡^ MB ^^^^^ In addition, such prior systems tend to be prone to the lens case being separated from the bottle for the lens care composition, particularly during transport, because the case of Lenses can be removed from the composition bottle for lens care relatively easily, and unintentionally.

BRIEF DESCRIPTION OF THE INVENTION New devices have been discovered which include containers, for example, containers for containing contact lens care compositions and for holding contact lens cases. The present apparatuses are of simple construction and require, if only a small complexity of manufacture, particularly with respect to the bottle for the composition for the care of the lenses. In addition, the containers are removable, however positively, they ensure one with the other, thus reducing the risk of the lens case separating unintentionally from the bottle for the composition for the care of the lenses. In addition, the present invention is directed to an improved cap assembly that inhibits undesirable leaks of the bottle lens care composition.

In a broad aspect of the present invention, an apparatus comprising a first container and a second container is provided. The first container defines a chamber adapted to contain a material, for example a liquid material, such as a liquid composition for the care of contact lenses. The first container has an outlet through which the material in the chamber passes when leaving the chamber. The second container defines a compartment and is adapted to be removably secured to the first container. The second container extends outwardly from the first container with the second container removably secured to the first container. The compartment of the second container is preferably sized and adapted to hold a case for contact lenses.

The first container has a closed end, preferably located substantially opposite the outlet. The second container has an open end preferably located in a close proximity to the closed end of the first container with the second container removably secured to the first container. .w. In a particularly useful embodiment, the second container is placed and removably secured to the bottom of the first container and can be considered as the shoe. or the basis of the combined system of the first and second containers. Accordingly, for example, the second container can be placed in a stacked relation to the first container with the second container being placed at the bottom of the system and the outlet of the first container directly opposite the followed container being located.

An important advantage of the present invention is that a contact lens case can be located in the compartment of the second container, instead of being directly attached to the first container. This reduces the risk that the contact lens case will unintentionally separate from the first container or bottle for the lens care composition. Because the first and second containers are insured from one to the other, it is rare that accidental or unintentional separation of the first and second recipient occurs. In other words, because a positive force is required, for example, manual force, to disengage the ^ ^ ^ * ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The first and second containers can be removably secured with each other using any appropriate coupling assembly. The selected coupling assembly is preferably manually operated, i.e. the coupling assembly can be engaged or activated using manual force and / or can be disengaged or deactivated using manual force.

In another useful embodiment, the first container preferably includes a surface of an outer peripheral side wall and the second container includes a surface of an internal peripheral side wall which is structured to engage coincidentally with the surface of the outer peripheral side wall for securing removably the second container with the first container. More preferably, the first and second containers are structured to allow manually overcoming the engagement of the surface of the inner peripheral side wall with the surface of the outer peripheral side wall. This characteristic is important because the removable securing of the first and second containers is maintained when manual force is absent & £ & * £ *** to avoid accidental separation, while at the same time being able to expire manually, when desired, in order to conveniently use the contents of the second container, for example, the lens case .

The first container preferably includes an outer peripheral surface and the second container includes a peripheral surface of one end adapted to rest substantially on the outer peripheral surface of the first container. This feature effectively provides a smooth transition between the first container and the second container, which is beneficial, for example, for aesthetic purposes, and in addition € > It is effective to keep the two containers secured one to the other, thus preventing accidental or unintentional disengagement of the two containers.

In a very useful embodiment, the outer peripheral surface includes a slit near the second end of the first container. The surface of the inner peripheral side wall of the second container includes at least one projection extending inwardly, and more preferably, numerous inwardly spaced projections adapted to be received and held in the groove of the outer peripheral surface to help at least removably secure the second container with the first container. The numerous inwardly spaced projections spaced apart from each other are preferably substantially located at the same distance from a closed end, for example, the bottom of the second container.

Preferably the present apparatus further comprises an assembly of a plug coupled with the outlet. The plug assembly includes a passage in fluid communication with the outlet and is adapted to provide the exit of the material, for example, the liquid contact lens care composition, from the chamber of the first container. A part of a lid is provided and adapted to move between an open position in which the passage is open and a closed position in which the passage is closed.

In a particularly useful embodiment, the passage is partially defined by a hollow projection and the cover part includes a grooved structure located and adapted to receive the hollow projection when the part of the cover is in the closed position. The grooved structure is separated from the hollow projection when the part of the cover is located in the open position. Preferably it is provided; ,. ^ & .A an elongated piece fixedly fixed to the grooved structure. This elongated piece extends into the passageway when the piece of the lid is in the closed position. As the elongated piece extends within the passage, the risk of undesirable leakage of the contents of the first chamber with the lid part in the closed position is reduced.

The grooved structure preferably has an open end into which the hollow projection passes when the hollow projection is received in the grooved structure. This open end includes an inwardly extending flange which is adapted to help hold the hollow projection in the grooved structure. Again, this reduces any undesirable leakage of the contents of the first container when the lid part is in the closed position.

The first and second containers may be made of any suitable material or of an effective combination of materials to meet the requirements of the application involved. In a very useful embodiment, the first container and the second container, as well as the cap assembly, are made of polymeric materials, more preferably thermoplastic polymeric materials. The first container is preferably sized to be - * - ^^ Magg ^^ ¡& ^ gH | B | s ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^ «í ^^^^. held in a human adult hand and can be squeezed, or be sufficiently flexible, using manual force, to facilitate the removal of material from the chamber of the first container.

In a particularly useful embodiment, the plug assembly is preferably a unitary component. That is, the plug assembly is produced as a single component or piece, for example, by molding a polymeric material or other techniques, many of which are conventional and well known in the art.

In another broad aspect of the present invention, combinations are provided comprising a first container, a liquid composition, a second container and a contact lens case. The first container defines a chamber that has an outlet. The liquid composition is located in the chamber and is effective for the care of contact lenses. The second container defines a compartment and is adapted to be removably secured to the first container. The second container extends outward of the first container with the second container removably secured to the first container. The contact lens case is located in the compartment of the second container.

In one embodiment, the liquid composition preferably includes a disinfectant component in an amount effective to disinfect a contact lens immersed in an amount of the liquid composition. A particularly useful example of the liquid composition is a multi-purpose solution for the care of contact lenses, which includes an oxidative disinfectant component and other functional components., such as surfactants, chelating agents, tonicity agents, wetting agents, viscosity modifiers and the like, and is effective, for example, as a contact lens disinfectant, a contact lens cleaning composition, a lens rinsing composition of contact, a rehumidification composition of contact lenses and the like. Several of these compositions are known in the art. A specific example of such multi-purpose solutions for the care of contact lenses is the multi-purpose solution for contact lens care sold by Allergan under the trademark Complete®.

The contact lens case is preferably adapted to hold two contact lenses submerged in an amount of the liquid composition contained in the > The first container. 4, In another broad aspect of the present invention, there is provided an apparatus comprising a container and a plug assembly. The container defines a chamber adapted to contain a material, for example, a liquid material, such as a composition for the care of contact lenses. The vessel has an outlet. The cap assembly is coupled, preferably permanently secured, to the container and includes a hollow projection defining a passage in fluid communication with the outlet and adapted to provide for eviction of the material from the chamber. A piece of a lid is included in the plug assembly and is adapted to move between an open J-position to which the passage opens and a closed position in which the passage closes. The lid part includes a grooved structure positioned and adapted to receive the hollow projection when the part of the lid is in the closed position, and to separate from the hollow projection when the part of the lid is placed in the open position. Each of the features discussed previously with respect to the plug assembly of the two container system can be :: used in combination with this container / plug assembly aspect of the present invention.

Any and all features described herein and any, and all combinations of such features are included in the scope of the present invention so long as those characteristics of any such combination are not mutually inconsistent.

Further aspects and advantages of the present invention are presented in the following description and in the claims, particularly when considered in conjunction with the accompanying drawings in which similar parts bear like reference numerals.

DETAILED DESCRIPTION OF THE INVENTION The invention is described here mainly in the context of the care of contact lenses. This is one _1__L »: _ ^ __ IL_ ~ '~ • *. - ^ tü? ^ - ^ - ^ z z ... - > - « "W - *» ^ -.- ~ -A ^ important application of the present invention. However, the invention is useful in other applications, particularly in applications where a liquid composition or a fluid, for example gaseous, vaporous, atomized or similar, and the like are used in conjunction with one or more articles that are normally stored. or transported separately from the compositions. Examples of such other applications include, but are not limited to, dental cleaning systems, adhesive systems, systems that include a liquid and a tool or implement for applying or otherwise using the liquid, and the like. Each of these applications is also included within the scope of the present invention.

Referring now to Figure 1, a combination bottle according to the present invention, generally shown as 10, is packaged to be sold with a plastic film wrap 12. This wrapper 12 includes printed information with reference to the product or products of the invention. the bottle 10 and is sealed to provide a packaging resistant to deterioration.

With reference to Figure 2, wherein the casing 12 has been removed, the bottle 10 includes a first container generally shown as 14, a second container generally shown as 16, and a plug assembly shown generally as 18 The first container 14 includes a peripheral side wall 20, a closed bottom end 22 and an outlet 24, shown in Figures 4 and 5. The first container defines an internal chamber 26 in which a multi-purpose liquid solution is included for the care of contact lenses 28, such as the product sold by Allergan under the trademark Complete®. Of course, other contact lens care products can be used in the chamber 26. The outlet 24 is in fluid communication with the chamber 26. The liquid solution 28 that passes outside the first container 14 passes through the outlet 2. The first container 14 is manufactured, for example, by molding, from a thermoplastic polymeric material, such as, but not limited to, high density polyethylene, low density polyethylene, polypropylene, poly (ethylene terephthalate) and the like, and it has sufficient flexibility to be manually tightened to facilitate the removal of liquid solution 28 from chamber 26, as desired. The first container 14 is dimensioned such that it is held or held in a hand by an adult human. For example, the first container 14 has a length of about 5 inches to about 10 inches from the end of the bottom 22 to the top end of the outlet 24 and a width, or diameter, of about 2 inches to about 5 inches. As shown in the drawings, the diameter of the first container 14 varies slightly along the length of the first container.

The second container 16 includes a peripheral side wall 30 and a closed bottom wall 32. As will be discussed hereafter, the peripheral side wall 30 defines an open top end 33 directly opposite the opposite wall of the bottom 32 of the second container 16 The second container 16 defines a housing compartment 34 in which a contact lens case 36 of conventional construction is located. Case 36 for contact lenses is adapted to contain two contact lenses spaced apart from one another and to provide an amount of solution 28 of chamber 26 that will be introduced into the interior of contact lens case 36 for immersion of the lenses. Contact lenses and treat Contact lenses. The second container 16 is manufactured, for example, by molding from a thermoplastic polymeric material, such as, but not limited to, high density polyethylene, low density polyethylene, polypropylene, poly (ethylene terephthalate) and the like, and ^ t ^^^ S? g ^^^^^^^^^^^ tí ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^ gj ^ g ^^^^^ g ^ preferably has a length from the closed bottom wall 32 to the open top end 33 in the range of about 1 inch to about 3 inches, and a width or diameter in the range of about 2 inches to about 5 inches. The compartment 34 defined by the second container 16 is larger than necessary to carry the case 36 for contact lenses. Therefore, the compartment 34 can be used to carry other supplies in addition to the contact lens case 36, for example, other contact lens care supplies, such as contact lens cleaning enzyme tablets and the like. This is a substantial advantage over the previous combined bottle systems in which only one lens case can be carried.

Although the shapes of both the first container 14 and the second container 16 shown in the drawings are generally circular cylinders, it should be understood that these containers may have any suitable shape and may be within the scope of the present invention. For example, instead of being generally circular in cross section perpendicular to the longitudinal axis 1! 3, as shown in the drawings, such cross sections may be generally oval, rectangular, polygonal and the like.

^^^ The second container 16 can be considered as a shim or base of the combination bottle 10 and is removably secured with the first container 1 i. Although this removable securing can be achieved by using a variety of structures, the drawings show a very useful modality for such removable securing.

With particular reference to Figure 3, the outer peripheral surface 40 of the peripheral side wall 20 includes a slit 42. The inner peripheral surface 44 of the peripheral side wall 30 includes a series of spaced projections 46 projecting inwardly.

(Figure 6) which are positioned so as to be received and held in the slit 42, as shown in Figure 3. The projections 46 are oriented substantially parallel with the bottom wall 32 and at substantially equal distances from the 32 background wall.

The peripheral side walls 20 and 30 have sufficient stiffness, such that once the projections 46 are located in the slit 42 they remain in place until the hook is dislodged, for example, by manual force.

In addition, the inner peripheral surface 44 optionally includes an inwardly extending rib 48 which is spaced from the projections 46. The lowermost portion 52 of the peripheral side wall 20 extends outwardly from the slit 42. This lowermost portion 52 is located in the space between the projections 46 and the rib 48 and contacts the inner peripheral wall 44 in the region 50. This placement of the lowermost portion 52 between the projections 46 and the rib 48, as noted above, is effective in securing the second container 16 with the first container 14. Alternatively, the rib 48 can be removed and the inner peripheral wall 44 can be substantially straight (in profile) downwardly from the projections 46. The lowermost portion 52 can be removed from the this position using manual force.

The combinations of the slit 42 and the projections 46, and the projections 46, and optionally the rib 48, and the lowermost portion 52 as a whole are effective to removably secure the second container 16 with the first container 14.

Additionally, the uppermost surface 56 of the peripheral side wall 30 is in a supporting relationship with the surface 58 extending inward from the peripheral side wall 20. When the second side is secured jSáfc ^^^^^^^^ * ^ g * ^ ¿^^^^^ - ^^^ ~ * fj ^^^^ g * container 16 with the first container 20, as shown in Figure 3, this support relationship provides a substantially smooth transition between the peripheral side wall 20 and the peripheral side wall 30, for example at the periphery 60. This feature is effective to provide the apparatus 10 with an aesthetically pleasing appearance and, in addition, reduces the risk of unintentional separation of the second container 16 from the first container 14.

To overcome the securing of the second container 16 with the first container 14, the two containers are held with the different hands of a user, for example, an adult human, and are twisted gently (not rotated) in relation to one another and / or they pull. This is sufficient to remove the second container 16 from the first container 14.

Before discussing in detail about the plug assembly 18 of the present invention, reference is made to Figures 7 and 8 which show a prior art plug device, generally shown as 110. This plug device 110 includes a body 112 and a removable cover 114 which is attached to the body by means of the strip 116. The body 112 includes internal cords 118 for - "- * - • - *» *** - «*« removably securing the device of the plug 110 to a bottle containing a liquid, not shown.In addition, the exit passage 120 of the liquid in the body 110 has a tapered shape down through the wall 122. This conical shape provides only a small opening for the liquid exit from the bottle through the passage 120. Although this small opening can reduce the risk of liquid leakage, the passage of the liquid out of the bottle is more difficult and delayed.When the device of the plug 110 is closed, the cover 114 is fastened to the body 112 and the receptacle 124 covers the projection 126 which defines a part of the passage 120 of the The lower inner side wall 128 of the receptacle 124 is structured to receive, in a matching joint relationship, the external side wall 130 of the projection 126 when the cover 114 is closed.

With respect to Figures 4 and 5, the plug assembly 18 is described in greater detail. Thus, the plug assembly 18 is mounted on the first container 14, for example, by interference assembly, adhesives, and the like and combinations thereof. Preferably, no threads are used in securing the cap assembly 18 with the first container 14. Securing the cap assembly by screwing with the first container can give COTIO? Irrr - • -ai * ^ '****' ^ »- -«? ~~ ^ - ~ ^, ^ ".. ^^ .. *, result that the cap assembly loosens or separates from the container and that the solution in the first container leaks or spills. The cap assembly 18 is preferably permanently secured to the first container 14, for example, such that said securing can not be overcome by manual force. In this context, the term "permanently" means that securing the cap assembly 18 with the first container 14 can not be overcome without destroying one or both of these components at least to the extent that the cap assembly and the container they can not make sure again.

The plug assembly 18 includes a base 70 which includes a surface 72 in abutting relationship with the top surface 74 of the outlet section 75 of the first container 14. The outlet 24 is defined by the outlet section 75 of the first container 14. The outer peripheral surface 77 of the outlet section 75 includes a single outwardly extending projection 79 which circumscribes the outlet 24. This projection 79 is effective for clamping the plug assembly 18 with the outlet section 75. The upper wall 76 of the base 70 includes a downwardly extending sealing ring 71 that includes a portion 73 extending outwardly. The sealing ring 71 is positioned such that the portion 73 contacts and seals against the inner peripheral wall 77A of the outlet section 75. ' Accordingly, when the base 70 is located within the outlet 24, the projection 79 comes into contact with the inner peripheral surface 81 of the base and the portion 73 comes into contact with the inner peripheral wall 77A. Such contact creates an interference or friction fit between the base 70 and the outlet section 75 and seals the outlet section 75 against undesirable liquid leaks. In addition, an adhesive may be used in the peripheral region 83 to secure the lower portion 85 of the base 70 with the first container 14. In either case, the cap assembly 18 is: fixedly or permanently secured to the first container L4 and the section outlet 75 is sealed against undesirable leaks of liquid in a position as shown in Figures 4 and 5.

The upper wall 76 of the base 70 includes a hollow projection 78 extending upwards, located eccentrically with respect to the upper wall 76, which defines a passage 80 which is in fluid communication with the outlet 24. The passage 80, the which has a substantially constant cross section, provides the solution 28 exit from the first container 14. The cover part 88 is flexibly secured to the base 70 by a flexible strip 93 and can be uncapped from the closed position, shown in Figure 4 to the open position shown in Figure 5. The open end 89 of the lid part 88 has a dimension large enough to receive the uppermost portion 95 of the base 70 when the lid part is in the closed position. A peripheral groove 97 is provided in the upper wall 76 such that the lid part 88 is placed on the upper part of the base 70 and provides a smooth transition when the lid part is in the closed position. The element 90 in the part of the lid 88 can be pushed up by an adult human to move the lid part 88 from the closed position to the open position. The lid part 88 can be manually moved from the open position to the closed position, as desired.

The lid part 88 includes a grooved structure 92 extending downwardly from the interior surface 94 of the lid part. An elongate projection 96 similar to a finger is located in the central part in the grooved structure 92 which defines a hollow space 98.

The end portion 100 of the finger-like projection 96 extending towards the open end 102 of the rib structure 92 has a relatively small cross-section or diameter relative to the rest of the body.

¡? The projection similar to a finger 96.

In addition, the end 102 of the grooved structure 92 extending out of the cap part 88 includes a rim 104 extending inwardly.

As shown in Figure 4, when the lid part 88 is in the closed position, the hollow projection 78 is received in the hollow space 98 of the rib structure 92. The end portion 100 of the elongated projection 96 is extends within passage 80. Flange 104 extending inwardly from rib structure 92, which does not have a corresponding structure or coincides with external side wall 87 of projection 78, is in a clamping contact with the wall external side 87 of the projection 78 and is effective to maintain a seal relationship between the elongate projection 96 and the passage 80. In this way, the passage 80 is effectively sealed against leakage of the solution 28 from the first container 14 when the piece of the lid 88 is in the closed position. This seal is effective regardless of the orientation of the first container 14. This is particularly useful when the container is used during travel or other situations in which the orientation of the apparatus 10 is beyond the user's reach.

The combination bottle 10 can be used as follows. After the bottle 10 is purchased, the package 12 is removed at least enough to allow access to the cap assembly 18 and the second container 16. When it is desired to treat contact lenses, the second container 16 ss removed manually from the first container, as described above. The lens case 36 is removed from the second container 16. The contact lenses are placed in the contact lens case 36. The part of the cover 88 moves from the closed position to the open position (Figure 5). An amount of the solution 28 is passed from the outlet 24 through the passage 80 into the compartments of the lens case 36. After a sufficient amount of solution 28 is placed in the lens case 36, the part of the cover 88 is returned to the closed position (Figure 4). The lens case 36, which contains the lenses, can then be placed back into the second container 16 and the second container can be secured back to the first container 14. Of course, the lens case 36 need not be located in the second container while the Contact lenses are treated. After an appropriate period of time, i.e., sufficient time to effect the desired treatment or treatments of the contact lenses in the lens case 36, the second container 16 is again removed from the first container 14. The lenses are Remove from the lens case and can be placed directly on the eye for safe and comfortable use. The solution itself for lens case 36 is removed. The lens case 36 is returned to the second container 16 and the second container is secured again to the first container 14, as described above.

The combination bottle 10 can be used repeatedly, as desired, to provide effective and periodic care of contact lenses. The combination bottle 10, together with the second container 16 including the lens case 36 secured to the first container 14 and the cover part 88 in the closed position very effectively allow the transport of a lens care system of contact in a single article.
