Description
- This present application is a non-provisional of U.S. Provisional Application Ser. No. 61/940,564, filed Feb. 17, 2014, the content of which is incorporated herein by reference in its entirety for all purposes.
- This disclosure relates generally to insulated beverage containers and more particularly to an insulated beverage container capable of melting snow.
- Hypothermia occurs when core body falls temperature below 95 degrees Fahrenheit affecting brain activity, breathing, and heart rate. Hypothermia can kill an unprotected person quickly. In fact, the majority of winter weather deaths in the US are due to overexposure to the cold climate. In the last ten years, over 17,000 deaths in the US were associated with exposure to excessive natural cold.
- Being in a car during a winter snow storm can temporarily help to protect you from the elements. However, when a car engine is running, carbon monoxide, a colorless, odorless toxic gas, is produced. Although this gas typically exits the car through the exhaust pipe, the exhaust pipe can become blocked with drifting snow, which can result in the carbon monoxide backing up into the cabin of the car. Exposure to carbon monoxide can cause headaches, dizziness, weakness, nausea, vomiting, and confusion and can kill you in as little as ten to fifteen minutes. Although you can protect yourself from such poisoning by cracking a window open, this in turn lets cold air into the cabin of the car, increasing the risk of hypothermia. In addition, engine operation is dependent on the amount of gas in the tank and thus cannot be run indefinitely. Even though one can run the heater off the car's battery if the engine is not running, it will drain the battery and often faster in colder weather.
- Staying warm, however, is not the only thing to be concerned about when caught in a winter snow storm. One must also stay hydrated because dehydration can be fatal in about three days. Although snow is often in abundance in a winter storm, it is not a good source of drinking water since eating un-melted snow will lower your body temperature and bring on hypothermia faster. Winter snow storms tend to catch people off guard or unprepared. Regrettably, passengers often do not have the proper emergency aid items, such as water, with them when they need them. As a result, there is a need for a device for melting snow into drinkable water in such circumstances.
- Although coils for heating beverages have been around some time, they have several disadvantages, making them undesirable in a winter storm situation. First and foremost, they require an electrical power source for usage, which may be limited or unavailable. Also, they are extremely dangerous to handle given that maximum temperatures can exceed 212° Fahrenheit. In addition, these devices are made to be used with liquids and not considered safe for use with snow or non-liquid materials. Contamination can also be an issue if the coil is not kept clean or is improperly stored. Portability is also an issue since the heating coil and the cup in which the beverage is heated are sold separately.
- Insulated tumblers for storing hot or cold beverages, such as those made by Tervis® or Camelbak®, have been available for some time. These tumblers, however, are designed only to maintain the temperature of the beverage that is being stored in it; they do not cool or heat the beverage, let alone change a substance from one state to another. In fact, their ability to maintain the temperature is sub optimal as the ambient temperature eventually cools hot beverages or warms cold beverages stored in these types of tumblers over time.
- Insulated travel mugs that plug into a USB port or a cigarette lighter adapter have more recently been developed to warm beverages while on the go. However, they can only be used when plugged into a car, making them of no use if one is away from one's vehicle. In addition, they can quickly drain a car's battery if plugged in when the engine is off.
- Of course, one could melt snow using one's own body heat, such as by placing a scoop of snow in one's hands. However, continued direct exposure to the snow can cause hypothermia to set in faster. Moreover, simply placing a container filled with snow in a warm location (i.e., between your legs) is impractical given the length of time it would take to melt the snow in this manner.
- There is therefore a need for a compact, portable and reusable device for melting snow into drinking water to prevent dehydration and hypothermia when stuck in a winter snow storm.
- In one aspect, a container assembly generally comprises a container including an interior space for holding a substance. A heating element is supported by the container for heating the substance in the interior space. A power source including a manually operated hand crank generator is mountable on the container and connectable to the heating element for energizing the heating element to heat the substance in the interior space.
- In another aspect, a container assembly kit generally comprises a container having an interior space for holding a substance. A heating element is supported by the container for heating the substance in the interior space. A power source is disposed in the interior space and removable from the interior space for mounting on an exterior surface of the container.

FIG. 1 is a front perspective view of asnow melting device 10. Thedevice 10 comprises of a double walledhollow container 12, a removably coupledlid 14 and apower source 16 removably attached to the container. As further shown inFIG. 2 , the walls of thecontainer 12 define an inner receptacle 18 disposed within anouter receptacle 20. The inner receptacle 18 defines aspace 26 within thecontainer 12 in which to receive snow. The inner receptacle 18 and theouter receptacle 20 are constructed (such as by blow molding) to form the unitary double-walled container 12 having a leak-proof insulatingchamber 22 between anouter surface 15 ofcircumferential wall 19 of inner receptacle 18 and aninner surface 17 ofcircumferential wall 21 ofouter receptacle 20. With such a configuration, the inner receptacle 18 is thermally insulated from the cold temperatures of the ambient atmosphere. As shown inFIGS. 1 and 2 , inner receptacle 18 andouter receptacle 20 include generallycylindrical sidewalls bottom walls Bottom wall 28 is preferably configured such that thecontainer 12 can be free-standing, andouter receptacle 20 andbottom wall 28 are preferably sized and shaped to fit within the cup holder of a car. Atop wall 23 defines a rim of thecontainer 12 and extends circumferentially around the top of the container betweencircumferential walls top wall 23,circumferential walls bottom walls chamber 22 from thespace 26 in the inner receptacle 18 and the surrounding environment. Whilecontainer 12 can vary in shape and size, it is preferably sized to accommodate at least 10 fluid ounces and preferably compact so as to fit within the glove compartment of a car when not in use. - The
outer receptacle 20 can be made from a variety of non-heat conducting material, and the inner receptacle 18 can be made from a variety of heat-conducting materials. Illustrative, non-exclusive examples of the type of material from which theouter receptacle 20 can be formed include plastic, polycarbonate, or stainless steel. Illustrative, non-exclusive examples of the type of material from which the inner receptacle 18 can be formed include stainless steel and aluminum. Thelid 14 can be made of a variety of materials. While it need not be made of the same material as the inner receptacle 18 and/orouter receptacle 20, for aesthetic reasons it may be made of the same material as theouter receptacle 20. Illustrative, non-exclusive examples of the type of material from which thelid 14 can be made include plastic, polycarbonate, or stainless steel. - The
lid 14 andouter receptacle 20 of thecontainer 12 are configured to permit selective and non-destructive removal and replacement of thelid 14 on thecontainer 12. With such a configuration, thelid 14 can be removed from thecontainer 12 to allow the snow to be placed in thespace 26 of the inner receptacle 18, secured to theouter receptacle 20 when the snow is being melted, and removed when a user wishes to dispense the melted snow (i.e., water) contained therein. When secured to thecontainer 12,lid 14 covers thecontainer 12 to not only restrict the melted snow from exiting thecontainer 12, but to also keep the heat generated from the melting process within the container, as well as prevent the cold temperature from the ambient atmosphere from cooling the snow. Thelid 14 andouter receptacle 20 may be constructed in a manner such that thelid 14 can be coupled to and uncoupled from thecontainer 12 in any number of known ways, such as through the use of threads (i.e., twist-top arrangement), or through snap-fit, friction fit or clasp arrangements. - The
lid 14 may also include a dispensing mechanism (not shown) which allows the melted snow to be dispensed for drinking without removal of thelid 14. In addition, thelid 14 can be constructed of a size and shape to allow it to be used to gather snow and fill the device without the need to touch the snow with one's hands or gloves. - As shown in
FIGS. 1 and 2 , the insulatingchamber 22 includes aheating element 30 helically wound and evenly distributed therein. Theheating element 30 is preferably wound and evenly distributed within the insulating chamber from a base of thecontainer 12 to a top of container to provide for even heat distribution throughoutspace 26 in the container. As shown inFIG. 1 , one end of theheating element 30 is electrically connected to thepower source 16. As previously mentioned, the insulatingchamber 22 is constructed such that it is sealed off from the inner receptacle 18 so none of the snow or resulting melted snow leaks into thechamber 22 from the inner receptacle 18. - The
heating element 30 can be made of any electrically conductive material, such as resistance wire, which heats up as current flows through the wire. To prevent dehydration, a person needs to drink more water than he or she loses in a day. Given the average urine output for adults is about 50 ounces a day, and given snow melts at approximately 335 Joules/gram, the voltage of thepower source 16 and the resistance ofheating element 30 are preferably selected so as to generate the heat necessary to melt at least 30 grams of snow per use. - The details of one exemplary embodiment of the
power source 16 ofFIG. 1 will now be discussed. Thepower source 16 may be a manually operated hand crank generator having anouter housing 40 connected to thecircumferential wall 21 ofouter receptacle 20, and acrank arm 42 which when in an operating position as shown inFIG. 1 is rotatable 360°. Although the connection between thehousing 40 and thecircumferential wall 21 may be permanent, thecircumferential wall 21 of theouter receptacle 20 and thehousing 40 are preferably configured to permit selective and non-destructive connection and disconnection of thehousing 40 to thecontainer 12. For example, thecircumferential wall 21 of theouter receptacle 20 may have a first connector (not shown) and thehousing 40 of thepower source 16 may have a second connector (not shown) for connecting and disconnecting thepower source 16 to and from thecontainer 12, respectively. With this configuration, thepower source 16 can be removed from thecontainer 12 and stored in thespace 26 when not in use. Thehousing 40 may also include a recessed area (not shown) in the shape of thecrank arm 42 for receiving thecrank arm 42 when it is in its resting position. - The
hand crank generator 16 includes agenerator 50 housed within thehousing 40 for converting the mechanical energy created by turning thecrank arm 42 into electrical energy. Anoutput 52 of thegenerator 50 is electrically connected to theheating element 30 and delivers power to the heating element when thecrank arm 42 is rotated. Thehand crank generator 16 is capable of generating at least six volts of power and preferably twelve volts of power. With a twelve volt configuration, it would take a user approximately five minutes of cranking thecrank arm 42 to melt 100 grams of snow. - In yet another embodiment of the
power source 16, thehousing 40 may include a receptacle or compartment 53 (FIG. 3B ) for receiving batteries so that thedevice 10 can be battery-operated. With such an embodiment, thehousing 40 includes an ON/OFF switch (not shown) electrically connected to the batteries for turning thedevice 10 on and off. - In another embodiment of the
power source 16, thehousing 40 may include a female USB port 54 (FIG. 3A ) for connecting thecontainer 12 to either a male USB port of the vehicle, or to the cigarette lighter of the vehicle through a male USB-cigarette lighter adapter (not shown), such as the Power Jolt car chargers for micro/mini USB devices made by Griffin Technology. In such a configuration, thedevice 10 includes a male-to-male USB cord (not shown) which can be stored in thespace 26 when thedevice 10 is not in use. The male-to-male USB cord may also be simply removed from thespace 26 when thedevice 10 is in use and powered by batteries or via the hand crank generator. - The location of the
female USB 54 port may be positioned at any suitable location on thehousing 40 of thepower source 16. In yet a further embodiment, one end of theheating element 30 may include a female USB port (not shown) housed within thechamber 22 but which abuts the outer wall of theouter receptacle 20. In this configuration,container 12 can be plugged into either a male USB port of the vehicle, or to the cigarette lighter of the vehicle through a male USB-cigarette lighter adapter (not shown), such as the Power Jolt car chargers for micro/mini USB devices made by Griffin Technology, via the male-to-male USB cord, thereby eliminating the need for a hand crank generator. - As described herein, the
device 10 can be powered from three different sources of power; namely manually through the hand crank generator, with batteries, or via the car's battery. It can also be appreciated that both the battery-operated and the USB/cigarette lighter versions of thepower source 16 can significantly reduce the time required to melt the snow. - In the illustrated embodiment, the
power source 16 is shown attached to thecontainer 12 near a base of the container. Thepower source 16 may be positioned at any suitable location on thecontainer 12 so that a user can hold thecontainer 12 in one hand while rotating thecrank arm 42 of the hand crank generator with the other hand. In one embodiment, thepower source 16 is positioned near the base of thecontainer 12 as shown inFIG. 1 . In another embodiment (not shown), thehousing 40 of thepower source 16 may be hingedly connected to thecontainer 12 and cylindrically shaped like thecontainer 12 and of a diameter such that it can pivoted to thebottom wall 28 of theouter receptacle 20 to form a base of thecontainer 12 when a user is finished cranking thecrank arm 42 so that thecontainer 12 can fit in a cup holder with the power source attached to the container. In this embodiment, the base of thecontainer 12 and/or thehousing 40 include mechanism(s) for securing thepower source 16 to the base of thecontainer 12. In addition, a portion of theoutput 52 of the generator may be housed in a retractable cord (not shown) allowing thepower source 16 to pivot. In another embodiment (not shown), thepower source 16 is positioned toward the upper part of thecontainer 12 so that when in use, the base of thecontainer 12 can fit in a car's cup holder with the power source attached to the container. - The
power source 16 is sized so as to be able to house the necessary parts (i.e., gears, generator, etc.) to produce at least 6 volts of power and preferably 12 volts. - In operation, a user places snow in the
space 26, either through the use of thelid 14 or with his or her hands. Once filled, the user secures thelid 14 to the top of thecontainer 12 and turns thecrank arm 42 of the hand crankgenerator 16 to generate a current in theheating element 30. As the user cranks thecrank arm 42, the snow is heated and begins to melt into drinking water. In addition, cranking thecrank arm 42 further warms the body of the user and help stave off hypothermia. Once all the snow has melted, the user can remove thelid 14 and begin drinking the water. With the battery-operated embodiment, the user simply turns the ON-OFF switch to the ON position to activate thedevice 10, and then to the OFF position to turn thedevice 10 off. With the car-operated embodiments, the user simply connects thedevice 10 to the female USB port or the cigarette lighter of the vehicle (through the USB-cigarette lighter adapter) to turn it on, and then unplugs it when the snow has melted into drinking water. - Referring to
FIG. 4 , thedevice 10 is preferably self-contained such that instructions 60 on use and the amount of water required to keep a person adequately hydrated to avoid dehydration, as well as all the parts necessary to operate it in its different power modes (i.e.,power source 16, male-to-male USB cord 62, and USB-cigarette lighter adapter 64) can be stored within thespace 26 when not in use. - Although the invention has been described as a snow melting device, the manually operated (i.e., hand crank generator) embodiment of the invention has applicability outside the winter storm setting. Specifically, one need only attend an outdoor sporting event when outdoor temperatures start to dip to appreciate the need for a container that not only provides insulation for a hot beverage, but also maintains the temperature of the beverage contained therein over time without the need for being close to an electrical power source. With this embodiment, the
container 12 may include a temperature indicator 66 (FIG. 4 ) to communicate the temperature of the beverage contained therein so a user knows when it has achieved the desired temperature. - Thus, embodiments of the invention are disclosed. Although the present invention has been described in considerable detail with reference to certain disclosed embodiments, the disclosed embodiments are presented for purposes of illustration and not limitation and other embodiments of the invention are possible. One skilled in the art will appreciate that various changes, adaptations, and modifications may be made without departing from the spirit of the invention.
- Having described the invention in detail, it will be apparent that modifications and variations are possible without departing from the scope of the invention defined in the appended claims.
- When introducing elements of the present invention or the preferred embodiments(s) thereof, the articles “a”, “an”, “the”, and “said” are intended to mean that there are one or more of the elements. The terms “comprising”, “including”, and “having” are intended to be inclusive and mean that there may be additional elements other than the listed elements.
