Description

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention is directed to a closure, which may include tamper evident capabilities as well as an integrated spout and cap, which may be removably attached in a closing relation to a neck portion and/or access opening of a bottle intended for the containment of a medical solution. One or more embodiments of the closure may also facilitate dispensing of the contained medical solution, or other contained solution.

Description of the Related Art

Ophthalmic preparations and solutions are commonly used to treat a wide variety of conditions, including, without limitation, allergies, bacterial and viral infections, and other eye conditions, such as glaucoma. Indeed, sterile ophthalmic compounds are currently widely used in 503A, 503B, eye institutes, and general hospital pharmacy facilities around the world. Likewise, ophthalmic preparations are widely used in veterinary compounding.

Generally speaking, a typical ophthalmic drug, when compounded, includes several components including, without limitation: an ophthalmic container assembly comprising a bottle, a cap, and a nozzle, which must be assembled and filled while maintaining an aseptic technique for the disposition of a liquid, such as a drug, therein. As may be understood, such aseptic techniques require strict procedures for preparing the drug, such procedures including the preparation thereof within a sterile, Class 5 clean room environment, the preparation therein under a laminal flow hood, and the avoidance of touching component surfaces which may contact the given drug. Because the bottle, cap, and nozzle of the ophthalmic container assembly are, at least initially, separate components, it may be understood the aseptic preparation of an ophthalmic drug can be difficult, time-consuming and labor-intensive. Indeed, one critical step in such a preparation is the assembly of the nozzle on the bottle in a dispensing orientation. As such, the nozzle will typically be in direct contact with the corresponding drug to be dispensed. As a result, the nozzle must be assembled into the ophthalmic container or bottle without personnel or exterior objects touching the nozzle. Such careful assembly must be practiced at least until such ophthalmic container has been filled with the intended solution.

Given these difficulties, there exists a need in the art for a solution to these problems pertaining to the preparation and/or compounding of ophthalmic drugs. If it were possible, one solution might be to develop an improved assembly having a cover structure to facilitate dispensing in the intended manner and a container, preferably in the form of a bottle, for the containment of the intended of ophthalmic or other medical and/or non-medical solution. If any such improved assembly were developed it would preferably also be structurally operative to facilitate maintenance of required sterile conditions by avoiding contact with a nozzle portion of the closure while being secured in fluid communicating relation to the interior of the ophthalmic container or bottle. Moreover, if any such improved assembly were developed it could prove helpful to include cooperative structuring of the closure structure to include a cap which may be secured to the ophthalmic container or bottle in a manner which eliminates or significantly restricts the possibility of contact with the nozzle, while concurrently enabling accurate, reliable and consistent placement of the nozzle in the intended dispensing orientation relative to the ophthalmic container or bottle, such as in an access opening thereof. Moreover, if any such assembly were developed it would preferably also be versatile with an ability to dispense the intended or prescribed solutions, compounds, etc. other than an ophthalmic solution.

SUMMARY OF THE INVENTION

The present invention is directed to an assembly for containment and dispensing of a solution specifically including, but not limited to, the containment and dispensing of an ophthalmic or other medical solution, preparation, compound, etc. Moreover, structural and operative features of the various components of the inventive assembly enable the intended attachment or connection to one another in a manner which maintains required or desired aseptic conditions or techniques. Such aseptic conditions or techniques include, but are not limited to the avoidance of contact with portions of the assembly which come into direct engagement with the solution, compound, etc. being dispensed. As is apparent from the detailed description of various embodiments of the present invention provided herein, the subject assembly may be specifically used for the droplet or “drop-by-drop” dispensing of an ophthalmic solution and as such, may be in the form of an eyedropper assembly. However, the versatility of the present invention enables the containment and dispensing of solutions other than ophthalmic or medical solutions.

Therefore, at least one embodiment of the present invention includes a closure for a container intended for retaining a medical or other solution, wherein the container may be in the form of a bottle. As explained in greater detail hereinafter, one or more embodiments of the present invention may utilize a somewhat conventionally structured bottle. In the alternative, a bottle having at least some customized structural and operative features may be utilized.

Further, in at least one embodiment of the invention, the closure includes a cap having a shroud with an open end through which a neck portion of the bottle passes to accomplish a connected, closing relation of the cap with the bottle's neck or neck portion. In cooperation therewith, a spout or nozzle is disposed in closing relation or engagement with an access opening of the bottle. The shroud of the cap is disposed, dimensioned and structured to surround and substantially enclose an at least partially hollow interior of the cap. Also, the closure may include an indicator member structured to provide evidence of tampering, such as by providing a clear visual indication of an initial removal of the cap from the aforementioned closing relation to the neck and/or access opening of the bottle.

In at least one embodiment, the indicator member includes a base and an indicator segment, wherein the indicator segment is removably and/or detachably connected to the base. As initially produced, the indicator member may be formed by injection molding and assembled by fixedly disposing, connecting or attaching the indicator member to an interior of the cap, and in such a secured position, the indicator member will preferably be disposed inwardly of the open end of the shroud. Also, in such a secured interior position, the indicator member will preferably not be visually observable from an exterior of the cap, when the cap is disposed in the aforementioned closed relation to the neck of the bottle and access opening. For purposes of clarity, it is emphasized that the preferably non-visually observable position of the indicator member while connected on the interior of the cap, and concurrent to the cap being secured or disposed in closing relation to the bottle is meant to describe that there is significant difficulty in an ability to view the indicator member. This is due at least in part to the cooperative structuring of the closure, including the cap and the dimension and configuration of the bottle, which would render viewing of the indicator member, while intact within the interior of the cap difficult, but not necessarily impossible.

As noted above, additional structural and operative features of the indicator member include a base and an indicator segment. The indicator segment is removably attached to the base of the indicator member preferably by a frangible, breakable connection. The structural features of such a frangible connection are such as to cause the breakage thereof and the detachment of the indicator segment from the base upon a removal of the cap from its connected, closed relation to the neck and access opening of the bottle. As described in greater detail hereinafter, the cooperative structuring of the cap and the exterior portion of the bottle neck may be such as to at least partially define a removable, threaded attachment of the cap to the neck of the bottle. Accordingly, an unscrewing or unthreading of the cap relative to the bottle neck will result in both rotational forces (torque) and axial load or force being exerted on the indicator member. In that the base is secured to the interior surface of the cap and/or shroud, it is movable therewith upon removal of the cap from the bottle.

Such removal force will be sufficient to break the frangible connection causing a detachment of the indicator segment from the base. Once so detached, the indicator segment will fall, pass or drop through the open end of the shroud onto a lower portion of the neck. The dimension and configuration of the shroud are such as to leave an uncovered space or opening on the neck below the open end of the shroud. Therefore, upon disconnection of the indicator segment from the base and the passage of the detached indicator segment through the open end of the shroud, it will be disposed within the opening or space on the bottle neck in a position which is clearly, visually observable. Therefore, the indicator segment will normally be disposed exteriorly of the shroud, even when the cap is reconnected in the closing relation to the bottle neck and access opening of the bottle.

Further, the visually observable location of the indicator segment, once detached from the base, will be sufficiently removed or spaced from the open end of the shroud to facilitate its visual observation. Accordingly, the tamper evident capabilities of the indicator member will include the clear visual observation of the indicator segment, once detached from the base of the indicator member, as the cap is removed or unscrewed from the neck of the bottle. Moreover, if and when the cap is replaced in closing relation to the neck and access opening of the bottle, the detached indicator segment will still remain exteriorly of the shroud and thereby, be clearly observable. Such observance will provide a clear indication that the cap had been previously and/or originally removed, rendering the contents of the bottle accessible and no longer sterile. In order to further emphasize the location of the detached indicator segment when disposed exteriorly of the shroud, it may include a bright or easily noticeable color, preferably distinguishable from the color of the cap or bottle.

Yet additional structural features of at least one embodiment of the present invention includes the indicator member, including both the base and the indicator segment, having a substantially annular or ring-like configuration. As such, the indicator member, when intact and fixedly connected to the interior surface of the cap, will be disposed inwardly from the open end of the shroud. When the cap is connected in the closing relation to the neck and opening of the bottle, the indicator member, including the base and the indicator segment, will be disposed in surrounding relation to the neck of the bottle.

In order to facilitate the aforementioned detachment of the indicator segment from the base, the indicator member is cooperatively structured with a portion of the neck of the bottle, such as with an exterior protrusion formed thereon, to enable a snap-fit connection therebetween. Such a snap fit connection is facilitated by a portion of the indicator member such as, but not limited to, the frangible structure or connection being at least minimally flexible. In cooperation therewith, the indicator segment or other appropriate portion of the indicator member will be cooperatively disposed and structured with the aforementioned exterior protrusion on the neck of the bottle. Therefore, when the cap is screwed onto or otherwise secured in closing relation to the neck and the access opening of the bottle, the indicator segment will movably engage and slide over an appropriately and cooperatively configured part of the aforementioned exterior protrusion extending outwardly from the outer surface of the bottle neck.

Therefore, such a snap-fit connection will further facilitate an initially secure engagement of the indicator segment with the neck of the bottle, when it is still attached to the base and while the base of the indicator member is fixedly secured to the interior surface of the shroud. However, upon detachment of the indicator segment from the base, the aforementioned snap-fit connection of the indicator member to the neck of the bottle will be broken, allowing the indicator segment to pass to a lower level of the neck. The indicator member will then be disposed exteriorly of the overlying shroud, including when the cap is replaced on the bottle after an initial or subsequent access to the contents of the bottle.

At least one embodiment of the closure of the present invention comprises an assembly which includes an integrated construction of the cap and spout. Such an integrated construction is operative to maintain the aseptic conditions during assembly of the cap, spout and bottle prior to the initial filling of the bottle with the selected ophthalmic or other solution. In more specific terms, and as recognized in the prior art, proper sterile conditions can be maintained by eliminating or significantly restricting the possibility of touching any structural part of the closure which comes into direct contact with the contained solution within the bottle. This specifically includes but is not necessarily limited to the spout.

Moreover, the aforementioned integrated construction embodied in the closure comprises the spout disposed in an initially fixed, but subsequently removable connection with the cap. As such, the spout is movable with the cap, as the cap is disposed in the aforementioned closing relation to the bottle neck. More specifically, when assembled the spout will be disposed at least partially into the access opening of the bottle and in sealing engagement therewith. However, due to the spout being integrated into a fixed, but removable connection on the interior of the cap, the spout will move with the cap, as the cap and spout are being connected, in the manner described, to the neck and access opening of the bottle. As should be apparent, the integrated location of the spout on the interior of the cap will prevent or significantly restrict it from being touched, while connecting the cap and spout to the bottle, such as subsequent to filling. In contrast, while the cap will be freely exposed in overlying in closing relation to the spout, it can be safely handled or manipulated to accomplish the connection of the cap and spout to the neck and access opening of the bottle. Aseptic conditions will be maintained because the cap will not come into direct contact with the ophthalmic solution or other contents of the bottle.

Further, the aforementioned fixed, removable integrated connection of the spout on the interior of the cap may be defined by a press fit or frictional engagement of the exterior of the outer segment of the spout with the interior surface of the cap. Such a frictional engagement and/or press fit attachment can be more specifically defined by one or more outwardly extending surface portions formed on the exterior surface of the outer segment of the spout. Therefore, the outer segment, including the one or more outer surface portions are disposed and dimensioned to accomplish the press fit, frictional engagement with correspondingly disposed interior surfaces of the cap. Such press fit or frictional engagement will be sufficient to fixedly but removably maintain attachment of the spout with the cap such as, but not limited to, during concurrent movement of the cap and spout into the closing engagement and/or relation with the neck and access opening of the bottle. In contrast, the un-threading of the cap from the neck of the bottle will result in a removal of the spout from the cap, as the cap disengages the neck of the bottle. This maintained placement and positioning spout in closing relation to the access opening is due at least in part to the fluid tight seal between the exterior surface of the inner segment of the spout and the interior surface of the bottle adjacent and/or contiguous to the access opening.

In the alternative, the integrated connection of the spout within the interior of the cap may be accomplished by a bayonet connector including two connecting segments. When utilized, different ones of the two connecting segments of the bayonet connector is attached to a different one of the spout, such as on the outer segment of the spout, and the cap, such as adjacent the interior surface thereof. The fixed connection and removable detachment of the two bayonet connecting segments facilitates a fixed but removable bayonet connection of the spout and the interior of the cap.

Yet additional features of the spout include the inner segment thereof being disposed in inwardly spaced relation from the exterior surface of the shroud. As indicated herein, the interior surface of the shroud may also include a connector structure, such as threads, which facilitate a threaded or rotational connection of the cap to the neck of the bottle. The inward spacing of the inner segment of the spout from the interior surface and connector structure of the shroud will allow the positioning of the outer end of the bottle neck to pass between the inner segment and the interior surface of the shroud, as the spout and the cap are secured to the bottle neck. As indicated, such attachment of the cap to the bottle neck will include the inner segment of the spout being disposed within and/or through the access opening in sealing engagement with the interior surface of the bottle contiguous to the access opening.

Structural details of the spout comprise the inclusion of a flow channel formed in the spout and extending therethrough. When the cap is connected to the neck of the bottle in closing relation thereto, the flow channel is disposed in fluid communication with an interior of the bottle, via the bottle access opening, concurrent to the spout being connected in closing sealing relation to the access opening of the bottle. When so connected, the spout is at least partially disposed within the bottle access opening, concurrent to the spout connected to the bottle neck. As with known dispensing of ophthalmic solutions, such as a conventional eyedropper, the dispensing of the ophthalmic solution is in droplets or by a “drop-by-drop” manner. Therefore, the dimension, configuration and overall structure of the flow channel, as well as the spout itself, may be such as to define a droplet dispensing of the fluid within the interior of the bottle.

In at least one embodiment, the present invention further comprises the closure having an integrated construction between the cap and a spout, but also being absent the hidden or shrouded indicator member, which is structurally operative to provide an indication of tampering. Moreover, this additional embodiment is directed to a closure comprising a cap including a shroud, wherein the shroud includes an open end. Further, the spout is connected in fixed, removable engagement with the cap to define the integrated construction therebetween.

As set forth above, such an integrated fixed but removable attachment ensures that the spout is movable with the cap into a closing relation to a bottle access opening. Similarly, the spout includes an inner segment disposed within the access opening of the spout in sealing engagement with the adjacent or contiguous interior surfaces of the bottle. As indicated, the spout also includes an outer segment disposed in the aforementioned fixed, but removable connection with interior surface portions of the cap, to define the aforementioned integrated connection therebetween. Also similarly, the inner segment is disposed in inwardly spaced relation to an inner surface of the shroud concurrent to the fixed, removable connection of the outer segment with the interior surfaces of the cap.

These and other objects, features and advantages of the present invention will become clearer when the drawings as well as the detailed description are taken into consideration.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The invention now will be described more fully hereinafter with reference to the accompanying drawings in which illustrative embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

The present invention is directed to an assembly generally indicated as 100 for the containment and dispensing of a solution specifically including, but not limited to, the containment and dispensing of an ophthalmic or other medical solution, preparation, compound, etc. Moreover, structural and operative features of the various components of the assembly 100 enable the intended attachment or connection to one another in a manner which maintains either required or desired aseptic conditions or techniques. Such aseptic conditions or techniques include, but are not limited to, the avoidance of contact with portions of the assembly which come into direct engagement with the solution, compound, etc. being dispensed. The subject assembly 100 may be specifically used for the droplet or “drop-by-drop” dispensing of an ophthalmic solution and as such, be in the form of an eyedropper assembly. However, it is again pointed out that the versatility of the present invention enables the containment and dispensing of solutions other than ophthalmic or medical solutions.

Therefore, and with initial reference to FIGS. 1-2, at least one embodiment of the present invention includes a closure generally indicated as 10 for a medical or other solution retaining container, which may be in the form of a bottle 12. As explained in greater detail hereinafter, one or more embodiments of the present invention may utilize a somewhat conventionally structured bottle. In the alternative, and as discussed in greater detail hereinafter, the bottle 12 may be structured to include at least some customized structural and operative features.

Further, at least one embodiment of the closure 10 includes a cap 14 including a shroud 16 as perhaps best shown in FIGS. 1, 3 and 4, having an open end 18 through which a neck portion 20 of the bottle 12 passes to accomplish a connected, closing relation of the cap 14 with the bottle neck 20. In cooperation therewith, a spout or nozzle 22 is disposed in closing relation or engagement with an access opening 24 of the bottle 12. The shroud 16 of the cap 14 is disposed, dimensioned and structured to surround and substantially enclose an at least partially hollow interior of the cap 14. Also, the closure 10 may include an indicator member 26, as perhaps best shown in FIGS. 3 and 4, that is structured to provide evidence of tampering to the extent of providing a clear visual indication of an initial removal of the cap 14, from the aforementioned closing relation to the neck 20 and or access opening 24 of the bottle 12.

As represented throughout FIGS. 1-9, in at least one embodiment, the indicator member 26 includes a base 28 and an indicator segment 29, wherein the indicator segment 29 is removably and/or detachably connected to the base 28. As manufactured, the indicator member 26 may be formed by injection molding and be assembled within the cap 14, preferably by fixedly disposing, connecting or attaching the base 28 to an interior portion, as at 31 in FIG. 6, of the cap 14 in a fixedly secured position. In such a fixedly secured position, the indicator member 26 is disposed on the interior of the cap 14 and in inwardly spaced relation to the open-end 18 of the shroud 16. Also, in such a secured interior position, the indicator member 26 will not be visually observable from an exterior of the cap 14, when the cap 14 is disposed in the aforementioned closed relation to the neck 20 of the bottle 12 and the access opening 24, as represented in at least FIGS. 1, 7, 9.

For purposes of clarity, it is emphasized that the non-visually observable interior fixed or secured disposition of the indicator member 26, while connected on the interior of the cap 14, and concurrent to the cap being secured or disposed in closing relation to the bottle 12, is meant to describe a significant difficulty of viewing the indicator member 26. This is due at least in part to the cooperative structuring of the closure 10, including the cap 14 and the dimension and configuration of the bottle 12 which would render viewing of the indicator member 26, while intact within the interior of the cap 14, difficult, but not necessarily impossible.

Additional structural and operative features of the indicator member 26 include a base 32 and an indicator segment 34. The indicator segment 34 is removably attached to the base 32 of the indicator member 26 preferably by a frangible, breakable connection 31. The structural features of such a frangible connection 31 are such as to cause the breakage thereof and the detachment of the indicator segment 34 from the base 32 upon a removal of the cap 14 from its connected, closed relation to the neck 20 and access opening 24 of the bottle 12. Further structural features of the frangible connection 31 comprise it including or being formed of at least one or a plurality of frangible segments 31′.

As represented in at least FIGS. 4 and 5, a connector structure 36 is formed on the interior of the cap 14 and more specifically, on the interior of the shroud 16. The cooperative structuring of the cap 14 and the exterior portion of the bottle neck 20 may be such as to at least partially define a removable, threaded attachment of the cap 14 to the neck 20 of the bottle 12. Accordingly, as at least schematically represented in FIG. 8, an unscrewing or unthreading of the cap 14, relative to the bottle neck 20, will result in both rotational forces (i.e., torque) and axial load or force 39 being exerted on the indicator member 26. In that the base 32 is secured to the interior surface of the cap 14 and/or shroud 16, it is movable therewith upon removal of the cap 14 from the bottle 12.

Again with reference to FIG. 8, the exertion of such a removal force (torque and axial load) will be sufficient to break the frangible connection 31, causing a detachment of the indicator segment 34 from the base 31. Once so detached, the indicator segment 34 will fall, pass or drop through the open end 18 of the shroud 16 onto a lower portion of the neck 20′ as represented in FIG. 9. The dimension and configuration shroud 16 are such as to leave an uncovered space or opening 20′ on the neck 20 below the open end 18 of the shroud 16. Therefore, upon disconnection of the indicator segment 34 from the base 32, and the passage of the detached indicator segment 34 through the open end 18 of the shroud 16, it will be disposed within the opening or space 20′ in a position which is clearly, visually observable. This visually observable position, as perhaps best represented in FIG. 9, of the detached indicator segment 34 would occur even when the cap 14 is reconnected or reattached in the closing relation to the bottle neck 20 and access opening 24 of the bottle 12, after an original or subsequent access to the contents of the bottle 12 has occurred.

Further, the visually observable location of the indicator segment 34, once detached from the base 32 (e.g., as shown in FIG. 9) will be sufficiently removed or spaced from the open end 18 of the shroud 16 to facilitate its visual observation. Accordingly, the tamper evident capabilities of the indicator member 26 will include the clear visual observation of the indicator segment 34, once detached from the base 32 of the indicator member 26, as the cap 14 is removed or unscrewed from the neck 20 of the bottle 12, as represented in FIG. 8. Moreover, if and when the cap 14 is reconnected or attached to the neck 20 in closing relation to the access opening 24 of the bottle 12, the detached indicator segment 34 will still remain exteriorly of the shroud 16 and thereby, be clearly observable as also represented and shown in FIG. 9. The ability to observe the detached indicator segment 34 will provide a clear indication that the cap 14 had been previously and/or originally removed, rendering contents of the bottle 12 accessible and no longer sterile. In order to further emphasize the location of the detached indicator segment 34 when disposed exteriorly of the shroud 16, it may include a bright or easily noticeable color, preferably distinguishable from the color of the cap 14 or bottle 12.

Yet additional structural features of at least one embodiment of the present invention include the indicator member 26, including both the base 32 and the indicator segment 34, having a substantially annular or ring-like configuration. As such, the indicator member 26 when intact and fixedly connected to the interior surface of the cap 14 and/or shroud 16, will be disposed inwardly from the open end 18 of the shroud 16. When the cap 14 is connected in the closing relation to the neck 20 and access opening 24 of the bottle 12, the indicator member 26, including the base 32 and the indicator segment 34, will be disposed in surrounding relation to the neck 20 of the bottle 12 as represented in at least FIG. 1.

In order to facilitate the aforementioned detachment of the indicator segment 34 from the base 32, the indicator member 26 is cooperatively structured with a portion of the neck 20 of the bottle 12, such as with an exterior protrusion 38 formed thereon, to enable a snap-fit connection therebetween, as represented in FIG. 6. Such a snap-fit connection is facilitated by a portion of the indicator member 26 such as, but not limited to, the frangible structure or connection 31 being at least minimally flexible. In cooperation therewith, the indicator segment 34 or other appropriate portion of the indicator member 26 will be cooperatively disposed and structured with the aforementioned exterior protrusion 38 on the neck 20 of the bottle 12. As also represented in at least FIGS. 6 and 8, the exterior protrusion 38 may have a slanted or angled surface as at 38′ thereby facilitating the movable sliding engagement of the indicator segment 34 therewith, so as to pass over the exterior protrusion 38 into the snap-fit connection as represented in FIG. 6. Therefore, when the cap 14 is screwed or threaded or otherwise secured onto the bottle 12, in closing relation to the neck 20 and the access opening 24, the indicator segment 34, while still being connected to the base 32 of the intact indicator member 26, will movably engage and slide over an appropriately and cooperatively configured exterior 38′ of the aforementioned exterior protrusion 38 extending outwardly from the outer surface of the bottle neck 20.

Therefore, such a snap-fit connection will further facilitate an initially secure engagement of the indicator segment 34 with the neck 20 of the bottle 12 when it is still attached to the base 32, and while the base 32 of the indicator member 26 is fixedly secured to the interior surface of the shroud 16, as set forth above. However, upon detachment of the indicator segment 34 from the base 32, the aforementioned snap-fit connection of the indicator member 26 to the neck 20 of the bottle 12 will be broken, allowing the indicator segment 34 to pass to a lower level 20′ of the neck 20. The indicator segment 34 will then be disposed exteriorly of the overlying shroud 16, including when the cap 14 is replaced on the bottle 12 after an initial or subsequent access to the contents of the bottle 12.

Moreover, in at least one embodiment of the present invention, the closure 10 comprises an assembly 100, which includes an integrated construction of the cap 14 and spout 22. Such an integrated construction is operative to maintain the aseptic conditions during assembly of the cap 14, spout 22 and bottle 12 prior to the initial filling of the bottle 12 with the selected ophthalmic or other solution. In more specific terms and as recognized in the prior art, proper sterile conditions can be maintained by eliminating or significantly restricting the possibility of touching any structural part of the closure 10 which comes into direct contact with the contained solution within the bottle 12. This specifically includes, but is not necessarily limited to, the spout 22.

With reference to at least FIGS. 2 and 3, the spout 22 includes an inner segment 23 and an outer segment 25. When the spout 22 is secured within the access opening 24, the inner segment 23 passes into the interior thereof and the exterior surfaces of the inner segment 23 define a fluid sealing engagement with the interior surfaces of the bottle 12, which are contiguous to the access opening 24. At the same time, the outer segment 25 extends outwardly from the access opening 24 and corresponding terminal end of the neck 20 of the bottle 12.

Moreover, the aforementioned integrated construction embodied in the closure comprises the spout 22 disposed in an initially fixed, but subsequently removable connection with the cap 14. As such, the spout 22 is movable with the cap 14 as it is disposed in the aforementioned closing relation to the bottle neck 20. More specifically, and when assembled, the inner segment 23 of the spout 22 will be disposed at least partially into the access opening 24 of the bottle 12 and in sealing engagement therewith. However, due to the spout 22 being integrated into a fixed, but removable connection on the interior of the cap 14, the spout 22 will move with the cap 14, when the cap 14 and the spout 22 are being collectively connected, in the manner described, to the neck 20 and access opening 24 of the bottle 12. As should be apparent, the integrated location of the spout 22 on the interior of the cap 14 will prevent or significantly restrict it from being touched while connecting the cap 14 and spout 22 to the bottle 12, such as subsequent to filling. In contrast, while the cap 14 will be freely exposed in overlying at least partially enclosing relation to the spout 22, it can be safely handled or manipulated to accomplish the connection of the cap 14 and spout 22 to the neck 20 and access opening 24 of the bottle 12. Aseptic conditions will be maintained because the cap 14 will not come into direct contact with the ophthalmic solution or other contents of the bottle.

Further, the aforementioned fixed, removable integrated connection of the spout 22 on the interior of the cap 14 may be defined by a press fit or frictional engagement of the exterior of the outer segment 25 of the spout 22 with the interior surface of the cap 14, as represented in FIG. 1 as well as the embodiment of FIGS. 10-14. Such a frictional engagement and/or press fit attachment can be more specifically defined by one or more outwardly extending surface portions 25′ formed on the exterior surface of the outer segment 25 of the spout 22 (see FIGS. 1 and 3). Therefore, the outer segment 25, including the one or more outwardly extending surface portions 25′ are disposed and dimensioned to accomplish the press fit, frictional engagement with correspondingly disposed interior surfaces of the cap 14. Such press fit or frictional engagement will be sufficient to fixedly but removably maintain attachment of the spout 22 within the cap 14 such as, but not limited to, during concurrent movement of the cap 14 and spout 22 into the closing engagement and/or relation with the neck 20 and access opening 24 of the bottle 12. In contrast, the un-threading or otherwise removal of the cap 14 from the neck 20 of the bottle 12 will result in a removal or detachment of the spout 22 from the cap 14, as the cap 14 disengages the neck 20 of the bottle 12. This maintained placement and positioning inner segment 23 of the spout 22 in closing relation to the access opening 24 is due at least in part to the fluid tight seal between the exterior surface of the inner segment 23 of the spout 22 and the interior surface of the bottle 12 adjacent and/or contiguous to the access opening 24.

In the alternative, the integrated connection of the spout 22 within the interior of the cap 14 may be accomplished by a bayonet connector 40 including two connecting segments 42 and 44, as represented schematically in FIG. 13. When utilized, different ones of the two connecting segments 42 and 44 of the bayonet connector 40 is attached to a different one of the spout 22, such as on the outer segment of the spout 22, and the cap 14, such as adjacent the interior surface thereof. A fixed connection and removable detachment of the two bayonet connecting segments 42 and 44 facilitates a fixed but removable bayonet connection of the spout 22 and the cap 14.

Yet additional features of the spout 22 include the inner segment 23 being disposed in inwardly spaced relation from the exterior surface of the shroud 16, as perhaps best represented in FIG. 1. As set forth herein, the interior surface of the shroud 16 includes the connector structure 36, such as threads, which facilitate a threaded or rotational connection of the cap 14 to the neck 20 of the bottle 12. The inward spacing of the inner segment 23 of the spout 22 from the interior surface and connector structure 36 of the shroud 16 will allow the positioning of the outer end of the bottle neck 20 to pass between the inner segment, as it passes into the access opening 24, and the interior surface of the shroud 16. This will occur as the spout 22 and the cap 14 are secured to the bottle neck 20 in the manner described herein and represented in FIG. 1. As indicated, such attachment of the cap 14 to the bottle neck 20 will include the inner segment 23 of the spout 22 being disposed within and/or through the access opening 24 in sealing engagement with the interior surface of the bottle 12 which is contiguous to the access opening 24.

Additional structural details of the spout 22 include a flow channel 22′ formed in and extending therethrough as clearly represented in FIGS. 1, 4 and 5. When the cap 14 is connected to the neck 20 of the bottle in closing relation thereto, the flow channel 22′ is disposed in fluid communication with an interior of the bottle 12, via the bottle access opening 24, concurrent to the spout 22 and the inner segment 23 thereof connected in closing sealing relation to the access opening 24. As with known dispensing of ophthalmic solutions, such as a conventional eyedropper, the dispensing of the ophthalmic solution is by droplets or by a “drop-by-drop” manner. Therefore, the dimension, configuration and overall structure of the flow channel 22′ as well as the spout 22 itself may be such as to define a droplet dispensing of the fluid within the interior of the bottle 12.

To further clarify the present invention, a sequential review of FIGS. 3-9 indicates the structural and operative features thereof. More specifically, FIG. 3 represents the closure 10 including the cap 14, spout or nozzle 22 and indicator member 26 ready for attachment or interconnection in an operative, intended manner. As represented in FIG. 4, the spout 22 is inserted into the interior of the cap 14 and in at least one embodiment the spout 22 may be fixedly but removably integrated with the cap 14 in the manner set forth above. After interconnection of the spout 22 on the interior of the cap 14, the indicator member 26 is secured in its at least a partially fixed operative position within the interior of the cap 14, as represented in FIG. 5. As indicated, such fixed attachment of the indicator member 26 is accomplished by a fixed attachment, securement, etc. of at least the base 34 to the interior surface of the shroud 16.

More specifically, FIG. 6 represents the detailed interconnection of the indicator member to the cap 14 wherein the base 32 is fixedly connected or secured to the interior surface of the shroud 16. At the same time, the hidden, shrouded indicator member 26, while still intact, is secured by a snap-fit connection to the protrusion 38 extending outwardly from the neck 20 of the bottle 12. Accordingly, while the indicator member 26 is still intact it, is disposed within the interior of the shroud 16 in a non-observable location when the closure 10 and cap 14 are secured to the neck 20 of the bottle 12, as represented in FIG. 7.

As described in detail herein, FIG. 8 represents a removal of the cap 14 from the neck 20 of the bottle 12 by virtue of a rotational force (i.e., torque) and/or axial load or force 39 being exerted on the cap 14 and shroud 16. Such removal force will result in a detachment of the indicator segment 34 from the base 32 of the indicator member 26 due to a breakage of the one or more frangible members 31′ which comprise the frangible connection 31. Upon such detachment, the indicator segment 34 will no longer be connected to the exterior protrusion 38 by the aforementioned snap-fit connection. As a result, the indicator segment will fall to a portion on the neck indicated in FIG. 9 as 20′, wherein such location 20′ is beneath and/or exterior of the shroud 16, including when the cap 14 has been reattached to the bottle 12 in closing relation to the neck 20 thereof, as also represented in FIG. 9. Moreover, in such a position 20′ the indicator segment 34 will be clearly visible and observable, thereby providing a possible indication of tampering and more specifically, provide a clear visual indication that the cap 14 has been initially or previously removed from the bottle 12.

As represented in the embodiment of FIGS. 10-14, in another embodiment the present invention comprises the assembly 100 (e.g., see FIG. 1) incorporating the closure 10′, including an integrated construction between the cap 14 and spout 22, but being absent the hidden or shrouded indicator member 26 of the type represented in the embodiment of FIGS. 1-9. Instead, the cover 10′ cap 14 may be totally absent a tamper indicating structure or in the alternative, may include an indicator member 26 connected to the exterior of the shroud 16 adjacent or contiguous to the open end 18. The fixed integrated connection of the spout 22 within the interior of the cap 14 may be accomplished by the aforementioned frictional and/or press fit engagement of the exterior surface of the outer segment 25 to the interior surface of the cap 14 and/or shroud 16 using similar structural features such as the aforementioned outwardly projecting surface portion 25′ as represented in FIG. 3. Accordingly, the spout 22 is integrated into the cap 14 by virtue of the connected fixed, but removable engagement of the spout 22 within the cap 14 to define the integrated construction therebetween.

In the alternative, and as also set forth above the fixed, removable integrated connection of the spout 22 within the interior of the cap 14 and/or shroud 16 may be accomplished utilizing the bayonet connector 40 as represented in FIG. 13. Therefore, and as represented, the integrated connection of the spout 22 within the interior of the cap 14 may be accomplished by a bayonet connector 40 including two connecting segments 42 and 44, wherein different ones of the two connecting segments 42 and 44 of the bayonet connector 40 is attached to a different one of the spout 22, and the cap 14. A fixed connection and removable detachment of the two bayonet connecting segments 42 and 44 facilitates a fixed but removable bayonet connection of the spout 22 and the cap 14.

In another embodiment of the present invention, the bottle 12 is adapted for containment of the solution to be dispensed. As such, the bottle may comprise a customized construction and be formed as one piece such as by injection molding. This customized bottle 12 may be specifically structured to accomplish interaction with the aforementioned hidden or shrouded indicator member of the embodiment of FIGS. 1-9. As so structured, the customized bottle 12 may include the aforementioned outer protrusion 38 as represented in FIGS. 6 and 8. In addition, and with reference to FIG. 12, the customized structuring of the bottle 12 may also include an additional rib-like member 37 which may be disposed and structured to effectively “catch” the indicator segment 34 as it is detached from the base 32 and passes outwardly from the interior of the shroud 16 through the open end 18 thereof.

Yet another embodiment of the present invention is represented in FIG. 15 and is directed to a tray, generally indicated as 50. The tray 50 may be utilized in a sterile environment for packaging and is also structured to facilitate the filling of the individual bottles 12. More specifically, the tray 50 includes a plurality of cavities 52, each or at least some of which include an elongated cavity segment 54 having a substantially elongated horizontal orientation and a smaller cavity segment 56 having a substantially vertical orientation. In use, and as represented, one or more bottles 12 prior or subsequent to being filled may be disposed in the cavity segments 54 having the aforementioned elongated configuration and horizontal orientation. Concurrently, and prior to being filled, one or more covers 10 or 10′ may be disposed in the smaller, generally vertically oriented cavity segments 56. However, during the filling procedure, the empty bottles 12 will be disposed in a vertical orientation in the cavity segments 56 so as to be disposed and maintained in a substantially upright orientation. Such an upright orientation facilitates filling thereof, and upon the filling of a bottle 12 being completed, a corresponding one of the covers 10 or 10′ is threaded onto the filled bottle in the manner described herein. Moreover, the one or more smaller cavity segments 56 may have an interior structure which restricts rotation of the contained bottle 12 during the rotational, threaded attachment of a cover 10 or 10′ thereto.

Since many modifications, variations and changes in detail can be made to the described preferred embodiment of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents.
