DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

(8) There is shown in FIG. 1 a flexible sealing lid and connector device 10 operatively attached to a baby bottle B. In certain preferred embodiments described herein, device 10 is used to sealably cover the upper end and attached nipple N of the baby bottle. However, in alternative embodiments, such as shown in FIG. 6, the sealing lid may be employed to similarly cover and seal various other types of drink container including, but not limited to, sippy cups, water bottles, travel coffee cups and mugs, etc. As used herein, the term drink container should be understood broadly to refer to and include any and all such items. The particular type of drink container with which the lid device may be employed should not be construed as a limitation of this invention.

(9) Device 10, which is depicted by itself in FIG. 2, comprises a flexible lid component 12 that is permanently interconnected to an annular container attachment band 14 by an elongate flexible connector element 16. The foregoing parts are preferably manufactured and interconnected in a unitary or a single piece construction. Each of lid component 12, attachment band 14 and connector element 16 typically includes a resiliently flexible material. A soft, elastomeric substance such as silicone is particularly preferred as being safe and effective for use with a baby bottle or child's sippy cup. Various alternative natural products, such as rubber, or synthetics/plastics, may also be employed within the scope of this invention. As shown in FIGS. 1-3, lid component 12 includes a cylindrical side wall 18 and a rounded or convex upper end 20 integrally joined to side wall 18. The lower end of the lid component's peripheral wall 18 includes a resiliently expandable neck 17 that operates to seal a bottle or other container closed in a manner described below. As best shown in FIG. 2, the lower end of lid component 12 is open and the lid component includes an interior chamber 19. The individual parts of device 10 may have various dimensions within the scope of this invention. Typically, lid component 12 has a diameter and a height that may vary between 2-4 inches. Connector element 16 may likewise be between about 2-4 inches in length. Bottle attachment strap 14 may have an un-stretched diameter of approximately 2-4 inches. Again, these dimensions maybe varied within the scope of this invention.

(10) An annular lid attachment band 22 is wrapped about peripheral side wall 18 of lid component 12. Band 22 is typically molded or formed unitarily with lid component 12 and composed of the same material comprising the lid component. Essentially, band 22 is simply a relatively thick ring of material formed annularly about, and yet unitarily integrated with the side wall 18 of lid component 12. The flexible lid component 12 may be molded or otherwise manufactured such that, as best shown in FIG. 2, a lower circumferential edge 24 of band 22 protrudes a slight amount inwardly from peripheral wall 18 within interior chamber 19 and an upper edge 26 of band 22 protrudes outwardly a similar degree from the exterior surface of peripheral wall 18.

(11) Connector element 16 is again composed of the resiliently flexible material forming lid component 12 and integral band 22. Connector element 16 may comprise a strap, cord or other type of elongate element. An upper end of connector element 16 is unitarily and permanently fastened to band 22. The opposite, lower end of element 16 is fastened in an identical manner to bottle or container attachment band 14. This band too is composed of resiliently flexible material as described above. Typically, band 14 is provided with a diameter that is slightly less than the diameter of the baby bottle or other drink container with which device 10 is used.

(12) Device 10 is operatively engaged and used with a baby bottle B or other type of drink or beverage container in one of several different ways. For example, as shown in FIG. 1, device 10 may be attached to bottle B so that the lid device sealably covers and encloses both the baby bottle nipple N and the screw on cap C, which are shown in phantom. In particular, bottle attachment band 14 is stretched open and the baby bottle container 30 is inserted through band 14. The lower attachment band is then allowed to return to its normal un-stretched diameter so that it snugly and securely grips the circumference of bottle container 30 as shown. Flexible lid component 12 is then placed over nipple N and cap C of bottle B and the upper end of the baby bottle is inserted into interior chamber 19 of lid component 12. The entire lid component is pulled or otherwise manipulated in a manner similar to pulling on a glove such that the lid component is pulled sealingly over the upper end of bottle B. In particular, resiliently expandable neck portion 17 of lid component 12 is stretched or resiliently expanded in the manner indicated by arrows 32. The expanded neck thereby sealably grips the outer surface of bottle B and, more particularly, bottle container 30. As a result, nipple N is sealably covered. Formula, milk or other contents of bottle B are thereby restricted from leaking or spilling from the engaged lid component 12.

(13) While device 10 remains engaged with bottle B, flexible connector element 16 secures lid component 12 to attachment band 14, even when the lid component is disengaged and removed from the upper end of bottle B. This permits a baby to be fed or liquid to be otherwise dispensed through nipple N as needed. This secure and permanent means of attachment prevents misplacement and potential loss of lid component 12. Unlike conventional devices, lid component 12 is not detachable from either integral band 22 or connector element 16. As a result, it is much more difficult to misplace or lose the lid component 12 as long as device 10 remains attached to the bottle or drink container by means of band 14.

(14) Device 10 can be used conveniently to sealably cover a baby bottle in the manner shown in FIG. 1 when a standard bottle lid (which is conventionally supplied with the bottle) is either lost or unavailable. Device 10 may also be employed as shown in FIG. 1 for bottles which do not include a standard lid or closure. In such cases, nipple N can be sealed even more effectively by manually collapsing lid component 12 in the manner shown in FIG. 4. After device 10 is engaged with bottle 12 in the manner previously described, and after resiliently expandable neck 17 of lid component 12 is stretched and engaged with the exterior surface of bottle B, lid component 12 is collapsed in the manner shown in FIG. 4 by pressing flexible side wall 18 above integral band 22 such that collapsed regions or dimples 50 are formed in lid component 12. This is accomplished simply by pressing fingers F against the side wall 18 of lid component 12. Alternatively, the convex top surface 20 may be pressed downwardly as indicated by arrow 60. In either event, air in the interior cavity of lid component 12 is forcibly expelled, for example as shown by arrows 72, and a suction is created within the interior chamber of the lid component. This more effectively seals the enclosed nipple N (shown in FIG. 1). Contents of the baby bottle are thus even less likely to leak or spill from the nipple into the attached lid component 12. This reduces the likelihood of messy spills when the lid component is eventually opened.

(15) Device 10 may also be utilized in the alternative manners as shown in FIGS. 2 and 3 respectively. For example, in the embodiment shown in FIG. 2, device 10 carries an optional plastic dome element 74 which is shown in phantom. The dome element generally conforms to the shape of the interior surface at the upper end 20 of lid component 12. See also FIG. 5. Typically, dome 74 has a diameter that is generally commensurate with that of the lid component (e.g. 2-4 inches). The dome may have a height of approximately 1 inch. As shown in FIGS. 2 and 5, the interior of dome 74 carries an integral sealing ring 76 that depends from the apex of dome 74. Ring 76 is analogous to the sealing ring used in standard baby bottle lids.

(16) Lid component 12 may be equipped with dome element 74 and utilized to sealably cover the nipple N of a baby bottle B in the manner best shown in FIG. 5. In particular, dome element 74 is removably inserted into the interior chamber 19 of flexible lid component 12 such that the outer surface of the dome conformably interengages the rounded top 20 of lid component 12. The lid component is then interengaged with the upper end of bottle B in the manner previously described. As shown in FIG. 5, this causes sealing ring 76 carried by the interior surface of dome 74 to engage and seal the upper, nozzle end of nipple N. As a result, when the lid component 12 is operatively engaged with bottle B the nipple is effectively sealed closed. Liquid in the bottle is restricted from leaking or spilling through the nipple and into the interior chamber 19 of engaged lid component 12. Spills that may otherwise occur when the lid is disengaged from the bottle are thereby significantly reduced.

(17) The use of dome element 74 is particularly helpful if the standard lid has already been misplaced or lost or if no standard lid is provided. Because the dome element is only about 1 inch in height, it typically allows at least a portion of the peripheral wall 18 of lid component 12 to be collapsed in the manner previously described. As a result, additional suction and sealing may be accomplished by lid component 12 in versions using the dome sealing element.

(18) Device 10 may also be utilized as shown in FIG. 3. If a standard lid or closure 40 is provided with the baby bottle, that lid may be inserted into the interior chamber of flexible lid component 12 as indicated by arrow 80. The resiliently flexible lid component 12 thereby holds and grips the standard lid 40 in a manner analogous to a snugly fitting glove. As a result, the standard lid is securely retained within the flexible lid component 12, which is in turn secured to the bottle by band 14 and connecting element 16. This provides additional security for the standard lid 40 and further reduces the possibility that the standard lid 40 may be misplaced or lost.

(19) The flexible sealing lid and connector device of this invention may also be employed to sealably cover a wide variety of other drink containers such as sippy cups, insulated cups, travel coffee mugs, water bottles, etc. For example, FIG. 6 discloses sealing device 10a operatively engaged with and covering the upper end of an insulated travel cup C. Once again, device 10a includes a resiliently flexible lid component 12a that is permanently secured to a container attachment band 14a through a flexible connector element 16a. Device 10a again features a molded, one piece construction wherein lid component 12a is permanently secured to an upper end of connector element 16a and an attachment band 14a is similarly secured to the opposite end of connector element 16a. Silicone and other natural or synthetic materials may be employed to mold or otherwise construct device 10. The dimensions of the individual components may be modified to accommodate the particular size of the drink container involved.

(20) In versions wherein the sealing lid device is used for items such as travel cups, a small aperture 90 may be optionally employed in the side wall 18a of lid component 12a for accommodating a drinking straw S. The straw is typically bent within the interior chamber of lid component 12a and directed into the cup through the dispensing opening of the standard lid attached to cup C so that the beverage contained in cup C may be consumed through the straw. In such versions, lid component 12a typically includes a flat, rather than a convex or dome shape. This allows device 10a to conform to and better accommodate a variety of standard flat topped lids that are commonly used with such beverage containers.

(21) It should be understood that device 10a may be attached to beverage containers either with or without standard lids attached. In cases where the standard lid is not attached, the seal may be improved and leaking and spillage may be reduced by again squeezing and collapsing the lid component 12 as shown in FIG. 6. Suction and sealing will be improved in such cases by also eliminating aperture 90.

(22) In operation, neck 17a is expanded to receive and grip the circumferential wall of cup C. This allows the lid component 12a to securely and snugly grip the cup. As in the previously described embodiments, device 10a provides for a number of benefits. The engaged lid component 12a remains attached to cup C both when the lid component is engaged and covering the cup and when it is opened. As a result, it is virtually impossible to misplace or lose lid 12a. The lid component also provides an effective sealing closure, which significantly reduces spillage and leakage from the cup, as well as the possibility of misplacing or losing the original standard lid employed with the cup. That lid remains enclosed by and securely retained within lid component 12a when that lid component is engaged with cup C.

(23) It should be understood that in each of the versions disclosed herein, the suction seal may be improved by lightly wetting or moistening the interior surface of the lid component neck or the exterior surface of the engaged bottle or container prior to collapsing the attached flexible lid component.

(24) From the foregoing it may be seen that the apparatus of this invention provides for a one-piece, flexible sealing lid and connector device for baby bottles and other types of drink containers. While this detailed description has set forth particularly preferred embodiments of the apparatus of this invention, numerous modifications and variations of the structure of this invention, all within the scope of the invention, will readily occur to those skilled in the art. Accordingly, it is understood that this description is illustrative only of the principles of the invention and is not limitative thereof.
