ThermoBuffer "ThermoBuffer" which controls the temperature of coffee and keeps it at the proper temperature

To drink good coffeeDevices for adjusting the temperatureThere are various, but immediately after putting down the temperature of coffee to the proper temperature, after 3 hours it keeps the tumbler as it is "ThermoBuffer"is.

I made Orin Hemminger.


Get up early……


I will make coffee quickly before going to work.



Pour the finished coffee into a tumbler ......


Well I go to work. I get into the car.


A bite before driving ...


And the coffee was too hot and burned.


So I will start over again. Before going to work ......


I will make coffee.




Get on a car ......


A biteful bite.


It has cooled down for a long time this time.


I will start over again. Put coffee beans in coffee maker ......



Push the button.


Pour coffee into the completed tumbler ......


I drink a bite before I start the car.


It seems that this time it was just right temperature.


What I was using was ThermoBuffer.


ThermoBuffer is a tumbler that controls the temperature of the liquid contained therein.


When you put in the coffee, quickly lower the temperature, keep the hot coffee at the temperature that you can drink the most deliciously within 2 minutes, then keep the proper temperature for 3 hours. For that reason, it is now possible to drink coffee deliciously up to the last drop.


It was too hot to carelessly ... ...


It got cold and warmed again ......


There is no need to put ice.


Usage is the same as ordinary stainless steel tumbler.


The inside of the tumbler has three layers.


Just pour the liquid there is OK.


So why is temperature control possible? That is, something is contained between the inner layers of ThermoBuffer. that is……


Yes, water. The water placed between the layers plays the role of a heat sink, which adjusts the temperature too high. Also, vacuum is present between the outer layers, which keeps the temperature constant for a long time.


In other words, after the space inside the water quickly lowers the temperature and makes the temperature of the coffee the proper temperature ......


The outer vacuum layer plays the role of a blanket.


This keeps the temperature of the coffee at about 57 - 71 degrees.


Let's see the temperature change of the paper cup and the vacuum insulated tumbler, and the coffee poured into ThermoBuffer. First of all, a paper cup. Although the range painted pink is suitable temperature, the temperature drops sharply, and after 40 minutes from pouring coffee it will cool down rather than the proper temperature.


Next, looking at the vacuum insulation tumbler, the temperature does not go down so easily, even after 90 minutes it has not yet reached the proper temperature.


The last is ThermoBuffer. Immediately after pouring the coffee, the orange color graph gets shimmer, and after 10 minutes it gets the proper temperature. Even after 100 minutes, it remains within the range of suitable temperature.


Let's experiment with three tumbler cups side by side.


ThermoBuffer reached the fastest at 160 ° C (about 71 ° C), which is a suitable temperature.



After 2 hours, the temperature of the vacuum insulation tumbler is about 78 degrees, the paper cup is about 46 degrees, the temperature is too hot or warm, but the ThermoBuffer is about 62 degrees and keeps the proper temperature.


The result was sought for in various ways ......


It was such a feeling. The middle is ThermoBuffer, and the back one is a prototype.


ThermoBuffer is currently in the process of seeking investment for commercialization, one item can be earned by investment of 30 dollars (about 2400 yen), and the number can be increased by increment. In the case of outside the United States, shipping costs will be charged separately $ 10 (about 800 yen).


The deadline is 23:59 on September 12 in local time.
