Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is related and claims priority to that U.S. Provisional Application No. 62/458,542 filed Feb. 13, 2017, entitled “COOLER APPARATUS, SYSTEM AND METHOD” by inventor Kenneth Steve Place, which is incorporated by reference in entirety.

FIELD OF THE INVENTION

The present disclosure relates to apparatus, systems and methods for cooling beverages in containers such as, for example, metal cans and plastic bottles during use by individuals.

BACKGROUND OF THE INVENTION

Chilled single-serving beverage containers, such as metal cans and plastic bottles, may be used with tight-fitting, passive insulating wraps such as “coozies.” The insulating wrap or coozie may be formed of insulating material such as foam and slipped over the outside surface of the pre-chilled beverage container when the beverage is being consumed from the container, and then removed and reused when the container is discarded. A plurality of the beverage containers may be pre-chilled in loose ice or ice water in an ice cooler, or pre-chilled in a residential general-purpose refrigerator or commercial beverage cooler at a restaurant, bar or retail store.

BRIEF SUMMARY OF THE INVENTION

Apparatus, systems and methods for chilling beverage containers as herein disclosed may overcome various shortcomings and deficiencies of present modes for chilling beverage containers. According to disclosed subject matter, deficiencies of existing apparatus, systems and methods for chilling beverage containers may be reduced or avoided. Such reducible or avoidable deficiencies of existing apparatus, systems and methods for chilling beverage containers may include, for example, limited effectiveness in maintaining the beverage container in a uniform, predictable cooled condition over an extended period of time. Other reducible or avoidable deficiencies of existing apparatus, systems and methods for chilling beverage containers may include, for example, the typical requirement of either removing the container in an undesirable, wet condition from a cooler containing ice or ice water, unless a general purpose refrigerator is available. Furthermore, even when a cooler of ice or general purpose refrigerator is available, persons who are generally constrained by mobility limitations or injury, or persons who may desire or need to remain seated in a wheelchair, residential seating, venue seating, or in an automobile, boat or other transport motor vehicle, may find it difficult, impossible or inconvenient to get up and walk or maneuver to the cooler or refrigerator, and then open it and select a pre-chilled beverage. In other situations, individuals may prefer not to drink a warm beverage that was pre-chilled to a desired cool condition or temperature, but since being removed from the refrigerator has sat out and allowed to become warm over a period. Particularly in view of the preceding, and other problems and deficiencies, need exists for improvements in the field of art.
Disclosed subject matter may include apparatuses, systems and methods for chilling a beverage container during consumption of the beverage from the container by an individual. In embodiments, for example, a system for chilling a beverage container may include a cool side heat sink in thermal communication between the container and a cold side of a thermoelectric cooler,

In other embodiments, the chilling receptacle 229 or sleeve may be formed of metal have a high degree of thermo-conductivity. In an exemplary embodiment, the beverage chilling system 200 may chill a beverage container 205 to 34 degrees F. where ambient temperature is 90 degrees F. In an exemplary embodiment, the beverage chilling system 200 may chill a beverage container 205 to 9 degrees F. where ambient temperature is 60 degrees F.
One embodiment of the present disclosure may include a 0.250′ wall thickness turned down to result in a 2.385″ sleeve/cup diameter may provide suitable conductivity, fitment and installation ease at 88 mm. The floor of an embodiment, due to the reinforcing and conductivity of the attached aluminum plate, may comprise a thinner material facilitate speed of temperature transfer. For example, a 20 gauge aluminum sheet may be suitable or may be thickened or thinned with a corresponding change in cooling rates. Between the two metals, a thin layer of thermal conductive paste may be provided to improve transfer of temperature. The sealing ring at the top of the sleeve may be in contact with the beverage container so as to be cooled efficiently by reducing atmospheric effects.
In some embodiments, the sleeve may be constructed of highly thermo-conductive metal. Some embodiments may include a minimum thickness of 1″ insulation or equivalent surrounding the sidewall of the chilling receptacle 229 or sleeve. In embodiments, the bottom of the chilling receptacle 229 may be joined to the cold surface of the thermoelectric cooler module 215 with thermal paste and stainless steel screws. The upper seal may be of a pliable nature to facilitate sealing on cups, bottles and a wide array of container sizes. A 10-amp fuse may be used in the wiring to prevent electrical problems. Condensation may be allowed to form and collect in the bottom of the sleeve/cup to enhance thermal conductivity and boost the performance.
It will be understood that embodiments may have increased capacity for heat exchange for cooling a beverage, for example, by including a Peltier device having larger cooling capacity, increasing heat transfer capacity from the beverage container to the thermal transfer device such as by providing direct contact between the thermal transfer device and metal beverage container, and increasing heat transfer capacity from the beverage container to the thermal transfer device such as by using thermal paste.
Countertop embodiments, may include a larger heat sink and larger thermoelectric cooling module 215, an aluminum container of different diameter, depth and wall thickness, and may include induced phenomenon of condensation to produce a water tight connection to the beverage container with increasing performance.
