Description
The present invention relates to temperature devices and in particular drinking temperature measuring and indicating devices.
Vast quantities of heated and cooled liquids are consumed each year by consumers throughout the world. Hot drinks such as tea, coffee and hot chocolate, are consumed at temperatures somewhere between 100°F and 150°F and for cooled drinks the optimum temperature seems to be between 32 ° F and 60 ° F.
Considering first of all coffee, the optimal brewing temperature of a coffee lies somewhere between 175 °F and 200°F. This is substantially higher than the optimal drinking temperature for coffee. Therefore, a certain cooling off must occur in order to avoid burning of for example the lips or tongue and for ensuring that the coffee is at the optimal drinking temperature.
In addition, beverages such as coffee, tea, hot chocolate, as well as cold beverages such as pop and beer are increasingly being consumed in disposable cups and containers.
Restaurants, coffee shops and the like which are dispensing hot liquids in disposable cups

Referring to Figures 1, 2, 3 and 4 a preferred embodiment of the present invention is a drinking temperature indicator 10 shown mounted in schematic representation on a disposable cup 20. Cup 20 has an outer wall 22, a rim 30 contains liquid 28 therein and an indicating area 24 having indicating letters 26 displayed upon the indicating area 24.
Referring now to Figure 1, cup 20 is shown schematically containing liquid 28 which has a temperature greater than 130°F. In this preferred embodiment 130°F is chosen as the indicating temperature, however in practice it could be any temperature desired. For the consumption of coffee in particular, 130°F is considered an optimal temperature for drinking coffee, therefore, the person consuming coffee from a disposable cup such as cup 20 would be interested to know when the temperature within the cup has reached or fallen below
-5-130°F. In addition, the dispenser of the coffee also would like to know when the contents of the cup has reached or fallen below 130 ° F in order to be able to serve the beverage at the optimal temperature and avoid burning the consumer. In Figure 1 in the indicating area 24, indicating letters 26 display the word "HOT". This word is made to come in contact with the outer wall 22 of cup 20 and is printed using thermochromic inks and/or other temperature sensitive plastics and/or materials which can be adapted to display the word hot as shown in Figure 1 and indicate a certain temperature as shown in this case 130°F. As long as the contents of cup 20 remains above 130°F the words hot and the indicating letters 26 will remain visible to eye in the indicating area 24.
Referring now to Figure 2 which again is a schematic representation of cup 20 showing indicating area 24. In this case, indicating letters 26 are disappearing or appear to be disappearing. This cup is demonstrating the drop in temperature of liquid 28 from above 13 0 ° F to some temperature below that. As liquid 28 in cup 20 falls below 13 0 ° F the indicating letters 26 being thermochromic in nature will begin to disappear.
Depending on which method is used, either the indicating letters 26 become transparent to the observer such that the background colour of indicating area 24 is seen by the observer and one can select the colour of the indicating letters 26 to match that of the indicating area 24. The result of
Referring now to Figure 2 which again is a schematic representation of cup 20 showing indicating area 24. In this case, indicating letters 26 are disappearing or appear to be disappearing. This cup is demonstrating the drop in temperature of liquid 28 from above 13 0 ° F to some temperature below that. As liquid 28 in cup 20 falls below 13 0 ° F the indicating letters 26 being thermochromic in nature will begin to disappear.
Depending on which method is used, either the indicating letters 26 become transparent to the observer such that the background colour of indicating area 24 is seen by the observer and one can select the colour of the indicating letters 26 to match that of the indicating area 24. The result of
-6-the process is that when the liquid 28 and cup 20 has fallen below 130°F the indicating letters 26 writing out the word "HOT" will have disappeared completely indicating to the consumer that it is now safe to drink the contents of cup 20.
It will be apparent to those persons skilled in the art in producing indicating type inks and working in the art of indicating particular temperatures will realize that any particular temperature can be selected that works within the medium used for the indicating letters 26.
Preferably thermochromic inks are used for applying indicator letters 26 to the outer wall 22 of cup 20 during the printing process when the graphics of the cup are applied. An l0 example of such ink is supplied by Chromatic Technologies Incorporated, 4320 North Park Drive, Suite B, Colorado Springs, Colorado 80907 with their product called Dynacolour TM
Thermochromic Flexographic Inks. In addition, the thermochromic ink can be applied to any drinking container including cups, mugs, but not limited to glasses, bottles and cans.
Referring now to Figures 3 and 4, a presently preferred embodiment of the present invention a Drinking Temperature Indicator is shown generally as 10 mounted on cups 20.
Referring now to Figure 3 specifically, liquid 28 contained in cup 20 is at a temperature greater than 130°F. Cup 20 has an indicating area 44 with a hot indicating mark 40 as well as a cold indicating mark 42. As shown in Figure 3 when the liquid 28 is _ 'j _ above 130°F the outer wall 22, of cup 20 heats up thereby also heating hot indicting mark 40 as well as cold indicating mark 42. When hot indicating mark 40 is heated to above 130°F it displays a red colour. When cold indicating mark 42 is above 130°F it shows in white and/or transparent colour, therefore, a consumer using this cup would see a red hot indicating mark 40 on the cup, the cold indicating mark would be white or transparent in colour and the indicating area could be any colour, however preferably as shown in yellow.
The red hot indicating mark would indicate that the contents liquid 28 of cup 20 are too hot to drink and therefore, sometime is required to allow liquid 28 within cup 20 to cool.
Referring now specifically to Figure 4 the liquid 28 within cup 20 is now below 130°F. Therefore, the outer wall 22 of cup 20 has had an opportunity to cool below 130°F
thereby also cooling hot indicating mark 30 as well as cold indicating mark 42 below 130°F.
As shown in the diagrams when hot indicating mark 40 is cooled below 130 ° F it becomes transparent or turns white as shown in Figure 4. When cold indicating mark 42 is cooled to below 130°F it turns green.
In general the hot indicating mark 40 and the cold indicating mark 42 are preferably applied to the outer wall 22 of cup as a thermochromic ink. Thermochromic inks change in colour when they are heated or cooled to a certain temperature. One is able to obtain different effects through use of different background colours and/or ink colours as shown in _g_ Figures 1 through 4. For example a thermochromic ink may be red in colour above 130°F
as the hot indicating mark 40 is in Figure 3 and below 130 ° F the hot indicating mark in fact turn transparent or for that matter another colour. The observer would see the colour on which the hot indicating mark 40 is printed on should the thermochromic ink become transparent. Referring to Figure 3 for example, hot indicating mark 40 is red above 130°F
and when cooled to below a 130°F it turns clear as in Figure 4. The white hot indicating mark 40 that we see is actually the colour of the surface upon which the hot indicating mark thermochromic paint has been applied to. Thereby one can create the illusion that the mark has transformed from red at above 13 0 ° F to white below 13 0 °
F when in actual fact the hot indicating mark 40 has transformed from red at above 130°F to transparent below 130°F.
It will be apparent to those skilled in the art that Figures 1 through 4 are just two examples of the way in which this drinking temperature indicator can be applied to disposable cups. There is no reason that the indicating area could be different or that the indicating letters and/or hot and cold indicating marks could take on different shapes or forms as the user would find aesthetically pleasing to the ultimate consumer.
The drinking temperature indicators warn and indicate when the liquid 28 contained within cup 20 is above a certain specified temperature and when it has cooled below a certain specified temperature.
Thereby the consumer is warned when the liquid 28 is too hot or uncomfortable to drink and is also given information as to when the liquid 28 is at a temperature that is comfortable and safe to drink.
A person skilled in the art will realize that the embodiments described in Figures 1 through 4 above are just two examples of a method of applying thermochromic paints to disposable cups for indicating whether the contents of cup 20 are above or below a certain specified temperature. It will also be apparent to a person skilled in the art that this method of indicating temperature described in the embodiments above, can also be applied to glass l0 beverage containers such as beer bottles, pop bottles and also to metallic cans such as for example, aluminum pop cans and beer cans.
It will also be apparent to those skilled in the art that this same method described in the embodiments shown in Figures 1 to 4 above can also be used to indicate optimal drinking temperatures for cold beverages as well as for hot beverages. Thermochromic temperature indicating paint are available for a range of temperatures, for example between approximately 25 °Fto 130°F . Many different ways of displaying whether a certain specified temperature has been exceeded, can be applied to cups, bottles and/or cans other than what has been shown in the examples of Figures 1 through 4. For example, any particular word other than hot can be displayed on the can. For example the words "COLD" or "HAVE A
NICE DAY" and/or "SURPRISE" and/or "YOU ARE A WINNER" and/or "SAFE TO
DRINK" could be applied to a disposable cup or bottle depending upon the message one wishes to convey to the consumer. In fact one is able to have one particular methods which a high temperature and another particular message at a low temperature depending upon how the thermochromic inks are applied to the container.
It is also possible to use this method for graphical effect such as displaying "lights"
on a Christmas tree or depiction on a side of a cup. When the liquid is hot the "lights" could take on a particular color and when the liquid is cold the "lights" could go out.
It will be apparent to those persons skilled in the art in producing indicating type inks and working in the art of indicating particular temperatures will realize that any particular temperature can be selected that works within the medium used for the indicating letters 26.
Preferably thermochromic inks are used for applying indicator letters 26 to the outer wall 22 of cup 20 during the printing process when the graphics of the cup are applied.
