## Background
RELATED APPLICATIONS
The present invention was first described in and claims the benefit of U.S. Provisional Application No. 61/137,748, filed Aug. 4, 2008, the entire disclosures of which are incorporated herein by reference.


FIELD OF THE INVENTION
The present invention relates generally to a insulated beverage sleeve and, more specifically, to beverage container comprising a thermal insulating sleeve, a temperature sensor and a temperature display and providing a means of holding and keeping cold a common beverage container while indicating the temperature of the same.
BACKGROUND OF THE INVENTION
Many people enjoy nothing more on a hot day than partaking in their favorite ice cold prepackaged beverage refreshments. Whatever one's taste, such drinks are usually consumed via a glass, bottle or can. To keep these drinks cold, many people resort to the use of insulated beverage holders, made of foam, that slip over the drink container. These holders have become widely used as a convenient method of insulating the cold drink from the warmer ambient temperature and the drinker's warm hand, thus keeping the drink cold longer. They also provide a comfortable alternative to gripping a cold and often wet drink container. However, after enough time, unfortunately any drink will become warm giving rise to the displeasure of unsuspecting consumers drinking warm and unappealing beverages. While these holders slow the warming of beverages, they lack any means of indicating to the consumer the temperature of the beverage.
Various attempts have been made to provide a means of indicating the present temperature of a beverage container. Examples of these attempts can be seen by reference to several U.S. patents. U.S. Pat. No. 2,319,101, issued in the name of Anderson, describes a bottle construction with temperature indicator having a thermometer built into a side wall of the bottle. The side wall of the Anderson bottle is constructed to uniformly vary in thickness to the point of location of the thermometer. U.S. Pat. No. 5,482,373, issued in the name of Hutchinson, describes a thermochromatic indicator for beverage containers. The Hutchinson indicator provides a temperature sensing assembly in the form of a thermometer and a temperature scale that is attachable to a beverage container. U.S. Pat. No. 5,897,207, issued in the name of Hartmann, describes a beverage temperature notification device. The Hartmann device comprises a thermosensor which is held in place by a sleeve to determine the temperature of the beverage. The thermosensor is coupled to a temperature indicator which signals to a user when the beverage has reached a desired temperature.
Additionally, ornamental designs for temperature measuring containers exist, particularly, U.S. Pat. No. D 343,129. However, none of these designs are similar to the present invention.
While these attempts fulfill their respective, particular objectives, each suffers from one (1) or more deficiencies or disadvantages. Typically temperature sensors placed on the beverage containers can be influenced by the ambient temperature as much as temperature of the container. Additionally, while the sensors may provide indication of present beverage temperature they do nothing to slow the warming of the beverage. Accordingly, there exists a need for a means by which the temperature of a cold beverage container can be readily determined while insulating the beverage from the ambient warm conditions without the disadvantages as described above. The development of the present invention substantially departs from the conventional solutions and in doing so fulfills this need.
SUMMARY OF THE INVENTION
In view of the foregoing references, the inventor recognized the aforementioned inherent problems and observed that there is a need for a cold beverage container holder that can be used with various types of containers which insulates the beverage from warmer ambient conditions and provides a means of sensing and indicating the present temperature of the beverage in a simple, durable, and user friendly manner. Thus, the object of the present invention is to solve the aforementioned disadvantages and provide for this need.
To achieve the above objectives, it is an object of the present invention to provide a beverage container insulating device with temperature indicating means which provides an insulated holder for use with beverage containers with an integral electronic temperature gauge, a digital display, and a pushbutton activation means.
Another object of the beverage container insulating device is to provide a device wherein the beverage holding means includes a cylindrical sleeve having side walls and a bottom portion made of durable, thermally insulating material into which a common cold beverage container can be easily inserted and removed. The sleeve provides a thermal barrier from warm ambient conditions to the cold beverage container and for an internal enclosure which houses the temperature sensing and display mechanisms.
Yet still another object of the beverage container insulating device is to provide a device wherein the principal temperature gauge includes an electronic thermistor encapsulated within an amount of thermal potting compound. The temperature gauge is housed with an internal enclosure positioned to be in direct contact with the outer wall of the beverage container.
Yet still another object of the beverage container insulating device is to provide a device wherein the digital display provides a simple and easy to read visual indication of the present temperature of the beverage. The temperature input signal is processed by a microcontroller and a display drive provides an output signal to the digital display.
Yet still another object of the beverage container insulating device is to provide a device wherein the digital display functions are simply controlled by the use of a user-engaged activation switch.
As an alternative, an object of the beverage container insulating device is to provide a device wherein the sleeve is designed to hold specific types of beverage containers such as bottles. In this embodiment the sleeve includes a tapered collar and an access system which provides thermal insulation to an upper portion of the beverage bottle.
Yet still another object of the beverage container insulating device is to provide a method of utilizing the device that provides a unique means of quickly assessing the temperature of a beverage prior to the surprise of drinking a warm beverage.
Further objects and advantages of the beverage container insulating device will become apparent from a consideration of the drawings and ensuing description.

Within said internal enclosure 60 are a battery access cover 70, a battery 75, a circuit board 80, a thermistor 85, electrical wiring 87, and thermal potting compound 90. A battery access cover 70 houses a battery 75, and preferably comprises a “coin style” battery 75 thereto allow said battery 75 to fit within the confines of the internal enclosure 60. Functionality and operation of the battery 75 will be described in greater detail below. A circuit board 80 which houses various converting circuits, a microcontroller 95, a display driver 100 (also see FIG. 4), and the like is provided therewithin the internal enclosure 60 as well. The circuit board 80 interfaces with the digital display 35 and the activation switch 40 through conventional internal electrical wiring 87. A conventional thermistor 85 is located on the rear of the internal enclosure 60 where it is encapsulated therein a conventional thermal potting compound 90, thereby obtaining corresponding readings directly from the exterior surface of the beverage container 14 as shown in FIG. 1. These variations are interpreted by the components on the circuit board 80 for display upon the digital display 35 when activated by the activation switch 40. These components will be described in greater detail herein below.
Referring to FIG. 4, an electric block diagram depicting the major electrical components as used in the device 10, according to the preferred embodiment of the present invention, is disclosed. Power from the battery 75 is routed through the activation switch 40 and fed to both a microcontroller 95 and a display driver 100 therewith conventional electrical wiring 87 of an appropriate gauge. The activation switch 40 is of a normally open; spring-return type design that closes the circuit when pressed. Other switching devices may be utilized such as, but not limited to: a toggle switch, a selector switch, or the like without limiting the functions of the device 10. The microcontroller 95 receives the temperature signal from the thermistor 85. The microcontroller 95 comprises a programmable intelligent computer (PIC) microcontroller, a basic stamp module, or similar type device which can receive and store operating sequences based upon a specific range of inputs. The output of the microcontroller 95 comprises a representative temperature, or a specific string of signals based upon range of input signals. The microcontroller 95 would also be calibrated with an appropriate multiple and offset to produce the necessary range of outputs as provided by the thermistor 85.
