INSULATED CONTAINER WITH INDUCTION HEATING
RELATED APPLICATIONS
There are no current pending applications.
I. Field of the Invention The present invention relates generally to the field of insulated containers utilizing induction heating.
II. Motivation for the Invention Coffee, tea, and other hot beverages are enjoyed by people almost every day.
Many people cannot start their day without a cup of their favorite hot beverage.
However, the start of the day also means a long commute in a car for many people. The popularity of travel mugs is evidence of the amount of coffee that is drunk while driving. For many people, a commute time of forty-five minutes (45 mm.) to one hour (1 hr.) is not uncommon. Even in the best insulated coffee mug, hot beverages will cool to an unacceptable level during this time.
These same problems exist for those who enjoy camping, hiking, and other outdoor activities, but a camp fire or propane stove is not convenient or feasible. Accordingly, a need has arisen for a solution to these problems associated with drinking hot beverages while away from conventional sources of power or heating. The development of the insulated container with induction heating element fulfills this need.

[0025] The best mode for carrying out the invention is presented in terms of its preferred embodiment, herein depicted within FIGURES 1-3, and in an alternate embodiment in FIGURES 4-6. However, the invention is not limited to the described embodiment, and a person skilled in the art will appreciate that many other embodiments of the invention are possible without deviating from the basic concept of the invention and that any such work around will also fall under scope of this invention. It is envisioned that other styles and configurations of the present invention can be easily incorporated into the teachings of the present invention, and only one (1) particular configuration shall be shown and described for purposes of clarity and disclosure and not by way of limitation of scope.
[0026] The terms "a" and "an" herein do not denote a limitation of quantity, but rather denote the presence of at least one (1) of the referenced items.
[0027] Referring now to FIGURES 1 and 4, a front view of the insulated container with induction heating element 10, according to a preferred and an alternate embodiment of the present invention, is disclosed. The insulated container with induction heating element 10 (herein described as the "device") 10, is comprised primarily of a main insulated double wall body 15 and a removable cup 20. The main insulated double wall body 15 is well known in the art and will be described in greater detail herein below.

It is envisioned that other styles and configurations of the present invention can be easily incorporated into the teachings of the present invention, and only one (1) particular configuration shall be shown and described for purposes of clarity and disclosure and not by way of limitation of scope.
[0026] The terms "a" and "an" herein do not denote a limitation of quantity, but rather denote the presence of at least one (1) of the referenced items.
[0027] Referring now to FIGURES 1 and 4, a front view of the insulated container with induction heating element 10, according to a preferred and an alternate embodiment of the present invention, is disclosed. The insulated container with induction heating element 10 (herein described as the "device") 10, is comprised primarily of a main insulated double wall body 15 and a removable cup 20. The main insulated double wall body 15 is well known in the art and will be described in greater detail herein below.
- 6 -Inventor: Aron L. Goddard [0028] The removable cup 20 is removable typically via a threading operation and maybe used as a drinking container. A removable thermal lid 22 (not shown due to illustrative limitations) is provided on the interior of the removable cup 20, and is used to provide a watertight seal with enhanced thermal insulation properties. The device 10 also provides other typical features as would typically be found on a portable insulated container for foodstuffs such as a handle 25 and rubberized protective strips 30, and could also be envisioned in the overall form of a standard water bottle, mug, as well as the depicted thermos. At least one (1) insulating grips 31, either located at the top of the cup 20 subjacent the lid 22, at the bottom of the container body 15, or both locations provide additional physical protection, gripping ability, and insulating properties. The inclusion or exclusion of any particular feature of the device 10, not necessary for the enhanced functionality of said device 10, shall not be interpreted as a limiting factor of the present invention. The device 10 would be used to hold, transport, heat, and retain heat of a variety of liquid foodstuffs including but not limited to water, milk, soup, tea, coffee, infant formula, hot chocolate, and the like.
[0029] Also visible on the lower portion of the main insulated double wall body 15 is a power connection jack 35. The power connection jack 35 is adaptable to a wide variety of external electrical power sources via external power supplies which will be described in greater detail herein below. Envisioned power sources include but are not limited to a 12-VDC car outlet (cigarette lighter), an AC electrical outlet, a USB
power sources, and an external battery pack which allow use of the device 10 virtually anywhere without reliance on fixed external power sources thus allowing use of the device 10 while camping, hiking, or engaging in other outdoor activities. This type of electrical heating ability does not rely of sources of combustion such as wood, coal, propane, natural gas, or the like, nor the large sources of external heat typically associated with a stove, burner, campfire and the like, that would be wasted for heating a relatively small amount of liquid foodstuffs.
[00301 The lower portion of the main insulated double wall body 15 is also provided with an on/off lighted touch sensitive pushbutton 40 for the purposes of energizing and de-energizing the electrical components of the device 10, an increase temperature setting

- 7 -Inventor: Aron L. Goddard switch 45, a decrease temperature setting switch 46, both for controlling the operational temperature of the device 10, a temperature indicator 50 for passively indicating the temperature of the contained foodstuffs within the main insulated double wall body 15, and a digital temperature display 51 for actively indicating the temperature of the contained foodstuffs within the main insulated double wall body 15. The on/off lighted touch sensitive pushbutton 40 provides visual indication of the operational status of the device 10. The increase temperature setting switch 45 and the decrease temperature setting switch 46 is utilized to pre-set a desired temperature, which will allow for the deactivation of the device when said temperature is reached. In a preferred embodiment (see FIGURES 1-3), the 10 switches 45, 46 are located adjacent each other on the body 15. In an alternate embodiment (see FIGURES 4-6), the switches 45, 46 would be provided as an integral component of the digital temperature display 51 (combined), as either separate mechanical pushbuttons or as a touch sensitive component of the digital display 51. Both methods are well-known in the art and can be easily incorporated. The specific inclusion or exclusion of any method of control is not intended to be a limiting factor of the present invention. Furthermore, the location (either separate or part of the digital temperature display 51 is not intended to be a limiting factor of the present invention. Further detail on the on/off lighted touch sensitive pushbutton 40, the increase temperature setting switch 45, the decrease temperature setting switch 46, the temperature indicator 50, and the digital temperature display 51 will be provided herein below.
[0031] A series of waterproof sealed covers 52 provide environmental protection for the on/off lighted touch sensitive pushbutton 40, the increase temperature setting switch 45, the decrease temperature setting switch 46 and the digital temperature display 51. This waterproof sealed cover 52 allows the device 10 to be utilized in rugged outdoor conditions such as construction sites, while camping or backpacking, or in similar rugged environments where the risk of immersion, contamination or physical impact is great.
[0032] Referring next to FIGURE 2 and FIGURE 5, sectional views of the device 10, as seen along a line I ¨ I, as shown in FIGURE 1 and FIGURE 4, respectively.
These figures clearly depict the inner components of the device 10 as well as provided insight

- 8 -Inventor: Aron L. Goddard on the operation of the induction heating system afforded. An inner container 55 is located on the interior of the main insulated double wall body 15 and is provided with an insulation area 60 included one (1) of air, foam, or other common insulating material. The inner container 55 is provided with an upper opening 65 allowing for the entry and removal of various liquid foodstuffs as aforementioned described. The removable thermal lid 22 is physically held in place via engagement means 70 such as threads. The removable cup 20 (as shown in FIGURES 1 and 4) is not shown in FIGURES 2 and 5 for purposes of illustrative clarity.
[0033] The actual heating of the foodstuffs 75 is provided by a metal plate 80 in physical contact with the bottom of the inner container 55. In turn, the metal plate 80 is heated by eddy currents produced by a high frequency coil 85. The high frequency waveform is produced by control circuitry 90 using processes and techniques that are well known in the art and not encompassed by the present invention. The power connection jack 35 provides electric power to the control circuitry 90. Further disclosure on power production through the power connection jack 35 will be provided herein below. The decrease temperature setting switch 46, along with interconnecting wiring is visible as well. The on/off lighted touch sensitive pushbutton 40 (as shown in FIGURES 1 and 4) is hidden from view due to illustrative limitations.
[0034] A tilt interlock switch 95 is also provided near the bottom of the main insulated double wall body 15. The tilt interlock switch 95 uses an electrical interlock to prevent operation should the device 10 be at a forty-five degree (450) angle or less to the horizontal position. This will prevent inadvertent operation should the device 10 be lying flat on its side.
[0035] Next, an over temperature limit switch 100 located near the bottom of the inner container 55, will shutoff operation of the device 10 should excessively high temperatures be reached. Such high temperatures may result if the inner container 55 is empty, or if the device 10 is activated to heat already hot foodstuffs 75. A
proximity interlock device 105 is located near the upper opening 65 to sense for the presence of the removable thermal lid 22 (as shown in FIGURES 2 and 5). The proximity interlock device 105, is

The tilt interlock switch 95 uses an electrical interlock to prevent operation should the device 10 be at a forty-five degree (450) angle or less to the horizontal position. This will prevent inadvertent operation should the device 10 be lying flat on its side.
[0035] Next, an over temperature limit switch 100 located near the bottom of the inner container 55, will shutoff operation of the device 10 should excessively high temperatures be reached. Such high temperatures may result if the inner container 55 is empty, or if the device 10 is activated to heat already hot foodstuffs 75. A
proximity interlock device 105 is located near the upper opening 65 to sense for the presence of the removable thermal lid 22 (as shown in FIGURES 2 and 5). The proximity interlock device 105, is
- 9 -Inventor: Aron L. Goddard envisioned to be a magnetic switch, a magnetic reed switch, limit switch, capacitive switch, photo sensitive switch, RF identification switch, or the like. The specific use of any particular style of proximity switch 105 is not intended to be a limiting factor of the present invention.
Should the removable thermal lid 22 (as shown in FIGURES 2 and 5) be present or too close to the main insulated double wall body 15, operation will not be possible due to prevent pressure build up inside the inner container 55 and possible subsequent explosion and physical injury to those nearby. Thus, the removable thermal lid 22 (as shown in FIGURES 2 and 5) must not be in place during operation of the device 10.
[0036] The temperature indicator 50 is visible on the exterior of the main insulated double wall body 15. The temperature indicator 50 is in physical contact with a thermal conductive link 110 such as a metal rod. The thermal conductive link 110 is then in physical contact with a temperature sensing patch 115 on the interior of the inner container 55. Thus, the temperature as present at the lower portion of the inner container 55 will be relayed to the temperature indicator 50. With the use of thermochromic chemicals, which are well known in the art, indication of the internal temperature will be apparent to the exterior of the main insulated double wall body 15. It is envisioned that various color such as red for hot, orange for medium, blue for normal or cold would be utilized. As the temperature indicator 50 does not require external sources of electricity, temperature indication would always be possible whether or not power is provided at the power connection jack 35.
[0037] Finally, the digital temperature display 51 is shown near the midpoint of the main insulated double walled body 15 for purposes of visually indicating the temperature of the contained foodstuffs 75 to the nearest integral degree The temperature displayed may be either Celsius or Fahrenheit, by either specific model control or be user control such as simultaneous energization of the device 10 while holding either the increase temperature setting switch 45 and the decrease temperature setting switch 46.
Such methods are well-known in the art and the specific use or omission of any particular method of temperature display change is not intended to be a limiting factor of the present invention.
