The present disclosure generally relates to a device that inhibits a beverage from spilling while modulating and/or regulating the temperature of the beverage so as to assist in maintaining a user-preferred beverage temperature.
Commuting to a place of employment is a common activity for most American workers, with over 85% of the workforce, or 128 million people, commuting to work in an automobile. The average commute time for an American worker was over 27 minutes in 2017, with the average commute time as high as 40 minutes in some metropolitan areas (U.S. Census Bureau 2017 American Community Survey.
A large number of Americans also choose to drink coffee and other warm beverages, with most of them preparing the beverage at home or purchasing a prepared beverage from a retail location. Coffee specifically will cool from brewing temperature to 60° C.—the ideal coffee drinking temperature—within 35 minutes or less, depending on conditions and the style of beverage container. Thus, it is apparent that for a large portion of Americans who commute to work, their coffee may be too cold to drink by the time they reach their desk or office.
It would be useful to develop an apparatus that will enable a user to maintain a desired elevated temperature for a beverage.
One embodiment described herein is an apparatus sized and configured to removably attach to a beverage container, the apparatus comprising a base and a moving agitator. In one embodiment, the base is configured to be removably attached to the outer surface of the beverage container. In other embodiments, the base is configured to removably attach to the opening of a beverage container lid. In some cases, the base is configured to be removably and frictionally attached to the beverage container or the lid.
In embodiments, the moving agitator is configured to fit through an opening of a beverage container lid. In some cases, the function of the moving agitator is not impaired by the absence of a lid. In embodiments, the base may further contain a battery or connection to a power source. In embodiments, the base additionally includes a control mechanism and an electrical mechanism. The agitator has a first end portion and a second end portion, wherein the first end portion is moveably attached to the base, and the second end portion is configured to have a larger surface area than the first end portion such that movement of the agitator can be effectively transferred to movement of the fluid. The first end portion of the agitator is configured to attach to the electrical mechanism, such that movement of the electrical mechanism is translated to motion of the first and second end portions of the agitator.
In some embodiments, a heating element, resistive or infrared, contained within the agitator is connected to the control mechanism. In other embodiments, the heating element is separate from the agitator. Optionally, one or more sensors may be contained within the agitator, communicably connected to the base and control mechanism, to provide input to the control mechanism. Those sensors may be one or more of a thermocouple, thermistor, temperature probe, semiconductor based integrated circuit (IC), resistance temperature detector (RTD), or other sensors known to those of skill in the art.
In one embodiment, a user may communicate with the apparatus to select a specific target or range of beverage temperature. A user may further specify a speed at which the agitator moves. The communication may be carried out through user interaction with the base, with user interaction with an external device such as a mobile phone, or other means of communication known to those of skill in the art.
One embodiment disclosed herein is a device comprising a base configured to removably attach to one of a beverage container and a beverage container lid, the base containing a power supply, a controller, a motor, and an agitator having a body and a length, with a first end portion including a first terminal end, the first end portion configured to be supported by the base, and a second end portion. The first terminal end is configured to be outside of the beverage container, and the second end portion is configured to be inside of the beverage container. In embodiments, the base contains a gear train and the motor is operably coupled to the gear train.
A method of using the above-described device also is disclosed, and comprises placing a lid with an opening onto a beverage container containing a liquid, affixing the device to the beverage container in an orientation allowing the body of the agitator to pass through the opening, and selecting a mode of operation for the device including at least one of a speed of motion for the agitator and a level of power for the heating element.
A further embodiment is a system comprising the above-described device, a portable beverage container having a liquid-holding capacity of no more than 40 ounces, a container lid with an opening through which to drink and which is configured to support the device when a user is not drinking, and an optionally connectable external power source.
Another embodiment described herein is a system comprising the device described above and a beverage container containing a liquid and an opening through which to drink; where the volume of the beverage container is no more than 40 ounces, or no more than 32 ounces, and the beverage container is portable; and an optionally connected external power source.
A further embodiment is a beverage stick comprising a heating and stirring component with a first end portion and a second end portion, the first end portion being configured to fit a sipping hole of a lid of a beverage cup, and the second end portion configured to contact a liquid in the beverage cup.
A solution to the problem described above is to provide a source of heat sufficient to slow the rate of cooling and extend the drinkable life span of coffee or other beverage, while also helping to agitate the brewed mixture such that it retains acceptable consistency along with temperature. The embodiments described herein comprise devices that are intended to agitate a liquid contained within a beverage container. Such a feature is useful where a drinkable liquid is not homogenous and requires agitation to ensure dissolved solids remain suspended in the liquid, as in the case of a brewed beverage like coffee or tea. Disclosed embodiments describe a unitary device that provides for simultaneous heating and agitation of a beverage disposed in a container, such as a single-serving beverage container.
One embodiment is a type of “splash stick” that inhibits a beverage from spilling from an opening in the lid of a beverage container and also modulates temperature of the beverage as directed by a user. An embodiment of the device has a heating element combined with a moving agitator, in order to allow the user to increase or decrease the temperature of a liquid and maintain a homogeneous consistency. The device may be sized to be small enough to fit securely into an opening in the lid of a beverage container, thereby not only preventing spills through the opening, but also allowing for convenient insertion and removal of the device from the container.
One embodiment may be comprised of a heating and stirring component with a first end portion and a second end portion, the first end portion configured to fit a sipping hole of a lid of a beverage cup, and the second end portion configured to contact a liquid in the beverage cup.
The device may further contain electrical and mechanical components. In one embodiment, an electrical mechanism creates the movement of a fluid agitator. Technology optionally can be included to measure the liquid's temperature. Heat can be applied or transferred to the liquid via technology, optionally, resistive or infrared components. The device may also use movement of the agitator to cool or heat a liquid, depending upon the temperature of the liquid and the speed of agitation. In one embodiment, the agitator can move back and forth, up and down, side to side, or swivel. Motion of the agitator may comprise one or more of those modes of movement. The agitator can take on many shapes and configurations, including but not limited to a propeller, spoon, paddle, whisk or wireform, or the like. In some embodiments, the agitator may be formed from a hard material, while other embodiments may feature a flexible agitator. Further embodiments may use an agitator with flexible and rigid portions. A portion of the agitator can be configured to deliver heat to the surrounding fluid. A variety of methods to do so may be implemented in embodiments, including an electrically resistive element or an infrared element.
Some embodiments may include means to communicate with a programmed application operating on a mobile device. The mobile device may be configured to allow the user to control various features and functions of the device, including but not limited to increasing or decreasing the temperature of the heating element, the mode of movement of the agitator, and the current temperature of the beverage.
Agitation is accomplished through the electrically-powered motion of an agitator, which may take the shape of a slender, elongated member such that it may fit through an opening in a beverage container. Motion may be imparted to the liquid through the use of that slender member, or optionally an integral or removable shape useful for moving liquid. Optionally, where the contained liquid has a temperature above room temperature, or where the user prefers to consume the liquid at a temperature above room temperature, the devices may introduce heat into the liquid to maintain and/or slow the rate of cooling of the contained liquid. Such a feature is useful for individuals who like to enjoy a warm beverage, like tea or coffee. It is apparent to consumers of such products that after a period of time, the temperatures of such brewed or mixed beverages may approach a low enough temperature as to make consumption of the beverage undesirable and unpleasant.
The device may also serve to duplicate the functions of a number of disposable or reusable devices, such as stir sticks, by providing a means to both agitate the beverage or liquid contained within a beverage container, while also blocking or obstructing any openings in the beverage container such that liquid may not easily spill or leak from the beverage container. The device may be easily removed and installed onto a beverage container for the purposes of cleaning or transition to a new beverage. The device may also be easily charged using a charging cable removably connected to a DC power supply, and the device may be powered using that same DC power supply or, optionally, through an on-board power storage device such as a battery. The device may be controlled, powered on, or powered off through physical interaction with the device itself. The device may be optionally controlled using a programmed application operating on a mobile device in wireless communication with the device.

The base 300 of the device 100 has a wall thickness, comprising a cavity surrounded by a wall forming a housing. In some embodiments, the housing may be injection molded in two or more pieces, and joined along the parting line 150 as one example, though the housing may be molded or formed in other planes and thus feature a parting line in an alternate orientation. In some embodiments, the internal components of the device may be installed into the housing prior to a unification process, where the process might be one of gluing, sonic welding, melting, or the use of positive engagement features and optionally a seal. In embodiments, the internal components may include one or more of a controller capable of regulating amperage and voltage in response to a variety of inputs, a motor in electrical communication with the controller, a gear train operably connected to the motor, an electrical connector capable of receiving power from a DC power supply such as a USB port, an on-board power supply such as a battery, and a proximate end portion 410 of the agitator 400. One or more of these components may also be installed on a printed circuit board or assembly, itself further secured within the housing through the use of bosses, key ways, compression, adhesives, or an independent structure. The proximate end portion of the agitator 410 may be supported directly by the gear train, or a separate bearing, or a pin riding on a surface of the housing where the pin is formed off of an end of the agitator. The motor and gear train may be further secured within the housing through the use of standoffs, key ways, compression, adhesives, or an independent structure. The gear train may be created from a planetary gear set to improve the torque output of a small electric motor, and optionally or in conjunction with a cam such that any contact between the gear train and the end of the agitator may be on a single point, frictional, yet non-continuous or impermanent. In embodiments, an on-off switch 306 is included on the base 300.
In preferred embodiments, the heating element is sized such that it is capable of delivering energy to the liquid sufficient to maintain the internal temperature of a freshly brewed cup of coffee above 50 degrees Celsius for a period of 30 minutes. In preferred embodiments, the agitator contains a heating element sized such that it is capable of delivering energy to the liquid such that the liquid remains above thirty degrees Celsius.
A number of alternatives, modifications, variations, or improvements therein may be subsequently made by those skilled in the art, which are also intended to be encompassed by the following claims.
