[00034] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[00035] Certain terminology is used in the following description for _ convenience only and is not limiting. The wards "right," "left," "upper,"
and "lower"
designate directions in the drawings to which reference is made. The words "inwardly" and "outwardly" refer to directions toward and away from, respectively, the geometric center of the system for use with a consumable beverage and designated parts thereof. The terminology includes the words above specifically mentioned, derivatives thereof, and words of similar import. Additionally, the words "a" and "one" are defined as including one or more of the referenced item unless specifically stated otherwise.

[00036] Referring to Figures 1-19, wherein like numerals indicate like elements throughout, a preferred embodiment of <~ system for use with a consumable beverage is shown and generally designated as 10. Briefly stated, the system includes a container 10 for enclosing a beverage 48 and a thermal energy storing member 44 therein to maintain the beverage 48 in either a chilled or heated condition. The thermal energy storing member 44 is preferably securable to either one of a collar 18 (further described below) or a lidl6 (further described below) via a convenient twist lock feature that allows the thermal energy member 44 to be easily disengaged from either component so that the remaining portions of the system can used with beverages while the thermal energy storing member 4~ is being heated or cooled. Additionally, the system 10 can be used with one of multiple interchangeable thermal energy storing members 44, to avoid delays caused by waiting for a single thermal energy storing member 44 to re-freeze or re-heat prior to continued use of the system 10.

[00037] The system 10 and its component parts are preferably formed from a sturdy, non-reactive, durable material, such as a suitable polymer. However, those of ordinary skill in the art will appreciate from this disclosure that the system 10 and its various components can be formed from any materials suitable for use with beverages. The thermal energy storing member 44 preferably contains a gelatinous material that is formed of re-freezable material and/o:r re-heatable material, such as the non-toxic materials used in gel packs and the like:.

[00038] Referring to Figures 1 and 2, the system 10 for use with a consumable beverage 48 includes a container 12 having a mouth 19~. While it is preferred that the container 12 is part of a sports bottle, those of o~°dinary skill in the art will appreciate from this disclosure that any type of container 12 can be used with the system 10 of the present invention. Similarly, while it is preferred that the mouth 14 of the container 12 is generally circularly shaped, t]nose of ordinary skill in the art will appreciate from this disclosure that the mouth 14 can have any shape without departing from the scope of the present invention.

[00039] The container 12 preferably has at least; one thread 52 positioned generally around a substantial portion of a perimeter of the container 12 proximate to the mouth 14 for engaging a lid 16. Alternatively, the container 12 can engage the lid 16 via a snap fit without departing from the scope of the present invention.

[00040] As best shown in Figure 4, the lid 16 is preferably detachably engagable with the container 12 by engaging at least one lid thread 54 with the at least one container thread 52. The least one lid thread 54 generally extends substantially around an inner surface of the lid 16 for detachably engaging the container 12. The lid 16 preferably includes a pull top 56 to allow the container 12 to be sealed when not in use.

[00041] As shown in Figures 4, 5, 7, and 8, the lid 16 is formed by a lid body that preferably has a tube section 34 for receiving a least a portion of the thermal energy storing member 44 therein. The tube section 34 is preferably generally cylindrical shaped.

[00042] The thermal energy storing member 44 can be attached to either one of the lid 16 or the collar 18 (further described below). The connection between the thermal energy storing member 44 and the lid 16 is as follows. Referring to Figures 2, 4, and 7, the thermal energy storing member 44 preferably has at least one groove 24 adapted to form, in combination with the tube section 34, a liquid passageway 26 through the lid 16 when the collar 18 is not used with the system 10.
Grooves 24 are preferably located on opposing sides of the top end 62 of the thermal energy storing member 44. Each groove 24 preferably extends generally inwardly into the thermal energy storing member to form a flared section 58.

[00043] Referring to Figure 8, when the thermal energy storing member 44 is engaged with the lid 16, a shoulder 60 of the thermal energy storing member 44 preferably abuts, or is proximate to, the bottom end of the tube section 34.
The flared section 58 of the grooves) 24 allows beverage 48 to flow from the inside of the container 12 through the flared section 58 and through tube section 34 (i.e., through the liquid passageway 26).

[00044] As best shown in Figures 2, ?, and 8 the upper end 62 of the thermal energy storing member 44 preferably has a generally oblong shape to allow opposing ends 64 to engage the inner surface of the tube section 34 while still leaving an opening that forms part of the liquid passageway 26 through which the beverage 48 can flow out of the container 12. Thus, the lid inner surface 66 is adapted to receive at least a portion of the thermal energy storing member 44 and is adapted to form, in combination with the thermal energy storing member 44, the liquid passageway 26 along the thermal energy storing member 44 and through the lid body 50. The routing of the liquid passageway 26 along the thermal energy storing member 44 results in the more efficient cooling (or heating) of the beverage 48 just prior to consumption thereof.

[00045] It is preferable that at least one thread 68 is positioned within the tube section 34 to engage the thermal energy storing member 44. The opposing ends 64 of the top portion 62 of the thermal energy storing member 44 preferably have recesses ?0 that are complementarily shaped to receive the tube section thread 68 of the lid 16. Thus, the tube section one thread 68 allows the inner surface of the lid 16 to detachably engage the thermal energy storing member 44 using a twist lock mechanism. This allows for quick and secure mounting of the thermal energy storing member 44. Additionally, this secure positioning of the thermal energy storing member avoids excessive shifting of the container's center of mass when the drink bottle is tilted.

[00046] As mentioned above, the thermal energy storing member 44 can also be secured to the collar 18. Referring to Figures 2-4, the collar 18 is adapted to be seated in the container mouth 14. Supports 72 are preferably positioned on a inner surface of the container 12 proximate to the mouth 14 to brace the bottom side of the collar 18.
This allows the collar 18 to be slid inside of the mouth 14 and braced by supports 72 such that the top surface of the collar 18 is generally aligned with the upper edge of the mouth 14. The collar 18 has a body 46 defining an opening 20 therein which is adapted to engage the end 62 of the thermal energy storing member 44. The opening 20 preferably, but not necessarily, has a generally cylindrical shape. The collar body 46 complements the shape of the mouth 14. The collar may include a plurality of holes to filter the consumable beverage therethrough and may include a microbial filter.

[00047] The thermal energy storing member 44 preferably has at least one groove 24 adapted to form, in combination with the collar 18, a liquid passageway 26 through the collar 18. Referring to Figure 5, when the thermal energy storing member 44 is engaged with the collar, the shoulder 60 of the thermal energy storing member 44 preferably abuts, or is located proximate to, the lower edge 74 of the collar 18. The positioning of the groove 24 generally below the shoulder 60 of the thermal energy storing member 44 allows the beverage 48 to pass through the groove 24 underneath the lower edge 74 of the collar 18 and through the liquid passageway 26. As the beverage 48 travels along the thermal energy storing member 44, the beverage 48 is chilled (or heated) to provide enhanced enjoyment to a drinker. The routing of the liquid passageway ~ along the thermal energy storing member 44 results in the more efficient cooling (or heating) of the beverage 48 just prior to consumption thereof.
[00048] Referring to Figures 3 and 6, the collar 18 preferably defines at least one vent 28 therethrough to create a second liquid passageway 30. The second liquid passageway 30 provides improved beverage flow 48 within the container.
The vents) 28 is preferably spaced from the thermal energy member 44.

[00049] It is preferred that at least one thread 32 is positioned within the collar opening 20 that is adapted to engage the thermal energy storing member 44.
The engagement between the collar thread 32 and the recess 70 in the thermal energy storing member 44 allows for a twist lock connection between the thermal energy storing member 44 and the collar that provides a secure placement of the thermal energy storing member 44 within the container 12. This prevents the center of gravity of a full drinking system 10 from suddenly shifting due to the movement of the energy storing member 44 therein. Additionally, the twist lock engagement between the thermal energy storing member 44 and the collar 18 provides for quick and easy removal and replacement of the thermal energy storing member 44 when desired. When the thermal energy storing member 44 is twisted and locked in position relative to the collar 18; the collar 18 is seated generally within the mouth 14 of the container; and the lid 16 is secured over the mouth 14 of the container 12, the energy storing member 44 and the collar 18 are secured in position. Thus, the collar 18 is securable in position when seated in the mouth 14 and the lid 16 is detachably engaged with the container 12.

[00050] As is clear from the above description of the engagement between the thermal energy storing member 44 and either the lid I6 or the collar 18, the thermal: energy storing member 44 is detachably engagable with the collar 18 and/or the lid 16. It is preferably that the end 62 of the thermal energy storing member 44 that wls attached to the collar 18 or the lid 16 is alignable along the longiaudinal axis of the container 12.
..

[00051] - The present invention also includes a method of providing a chilled consumable beverage. The method includes the steps of providing a container 12 having a mouth 14 and placing a consumable beverage 48 in the container 12.
The .method also. includes chilling a thermal energy storing member 44 and inserting the chilled ,thermal energy storing member 44 into the container 12 such that the .
chilled thermal energy storing member 44 contacts the consumable beverage 48 to cool ahe beverage 48 enclosed within the container 12. The chilled thermal energy.
storing member 44 is securely positioned within the container 12 via a collar .18 seated proximate to the mouth 14 of the container 12. The method of the present invention preferably includes securing a lid 16 over the mouth 14 that also secures.
the collar 18 in the seated position and inserting the chilled thermal energy storing member 44 within the opening 20 in the collar 18 such that a liquid passageway along the chilled thermal energy storing member 44.and through the collar 18 is formed. The method of the present invention preferably includes providing a collar 18 having at least one vent 28 therethrough to form a second liquid passageway through the collar 18. The at least one vent 28 is preferably spaced from the opening 20.

[00052] Referring to Figures 10-12, a second preferred embodiment of the system 10 for use with a consumable beverage 48 is shown. Except as otherwise noted, it is preferred that the components of the second embodiment function generally the same as the equivalent components in the first embodiment.

[00053] As best shown in Figure 13, the lid 16 is preferably detachably engagable with the container 12 by engaging at least one lid thread 54 with the at least one container thread 52. The least one lid thread 54 generally extends substantially around an inner surface of the lid 16 for detachably engaging the container 12. The lid 16 preferably includes a pull top 56 to allow the container 12 to be sealed when not in use.

[00054] Referring to Figures 12, 15, and 18, a filtering collar 18 is adapted to filter the consumable beverage 48. The thermal energy storing member 44 is preferably, but not necessarily, attached to the lid 16 and includes a portion that extends through the collar 18.

[00055] Referring to Figures 13 and 14 the collar can be positioning on at least one projection located on an inner surface of the container. Referring to the Figures 16, 17, and 19, the collar can be sandwiched between the top of the container 12 and the lid 16.

[00056] Referring to Figures 17 and 18 the collar 18 can include a charcoal filter or multistage filter without departing from the scope of the present invention.
_ Alternatively the collar can include a chlorine component to purify the consumable beverage 48.

[00057] Referring to Figures 1-9, one embodiment of the system 10 for use with a consumable beverage 48 operates as follows. The lid 16 is removed from the container 12 and the combination collar 18 and thermal energy storing member is removed from the container 12. Once the combination collar 18 and thermal energy storing member 44 are removed from the container 12, the thermal energy storing member 44 is twisted to disengage the recesses '10 from the collar thread 32 to allow to the thermal energy storing member 44 to be separated from the collar [00058] Then, the thermal energy storing member 44 is heated or chilled as desired and the container 12 is filled with a consumable beverage 48 and the heated or chilled thermal energy storing member 44 is engaged with one of the collar 18 or the lid 16 to maintain a desired beverage temperature. To attach the thermal energy storing member 44 to the collar 18, the upper end 62 of the thermal energy storing member 44 is inserted into the opening 20 of the collar 18 and twisted to engage the recesses 70 with the collar thread 32. Thi;~ twist lock feature securely positions the thermal energy storing member 44 relative to the collar 18 and relative to the container 12.

[00059] Once the thermal energy storing member 44 is attached to the collar 18, the combination is inserted into the mouth 14 of the container 12 with the underside of the collar 18 resting on supports 72. Then, the lid 16 is secured over the mouth 14 to sandwich the collar 18 in position between the supports 72 and an inner surface of the lid 16.

[00060] Alternatively, when the thermal energy storing member 44 is attached to the lid 16, the upper end 62 of the thermal energy storing member 44 is inserted into the tube section 34 of the lid 16 and twisted to engage the recesses 70 with the lid thread 68. Thus, the thermal energy storing member 44 uses the advantageous twist lock securing feature regardless of whether the thermal energy storing member 44 is secured to the collar 18 or to the lid 16.

[00061) The liquid passageways formed by the groove 24 of the thermal energy storing member 44 and one of the collar 18 and the lid 16 allow for beverage 48 to flow along the thermal energy storing member 44 toward . the pull top 56 of the container 12 and enhances the heat transfer efficiency of the system.
Additionally, by securely positioning the thermal energy storing . member 44 along the longitudinal axis of the container 12" sudden shifts in the center of gravity of the ,.
system 10 due to tilting of the container are reduced. This simplifies the handling of the container 12: Furthermore, the efficient and simple twist lock mechanism for securing the thermal energy storing member 44 allows the cooling (or heating) element of the system 10 to be removed while still allowing the system 10 to be used for drinking. Multiple thermal energy storing members 44 can be used with a single lid 16 and container 12 combination.
