Description

Thermos Bottle

The present invention relates to a thermos used to maintain the temperature of the contents.

As shown in the cross-sectional view of FIG. 1, a typical thermos bottle is surrounded by an outer shell 12 as a whole, and an insulation space 13 between the inner shell and the outer shell is a closed space in a vacuum state. to be. As such, when the insulation space surrounds the endothelium 11 as a whole, insulation is effectively performed, and thus it is good to maintain the temperature of the contents. However, when the temperature of the contents is too low, and the temperature is to be raised again, the conventional thermos having the above structure is directly heated. Since the temperature of the contents can not be raised, the contents can only be taken out of the thermos and put in another container for heating.

In recent years, the active leisure activities for health have increased, and the population of light trails for one day to the nearby mountains is increasing. However, in most nearby hikes, there is no facility for cooking in the mountains, and it is forbidden to make fires in the mountains. Therefore, mountaineers are taking hot water in a thermos at home to eat coffee, soup, or cup ramen while hiking, but if you open the thermos to use hot water in the mountain, the water is often cool. The problem to be solved by the present invention, when the temperature of the contents in the thermos is lowered again to raise the temperature, without having to take out the contents from the thermos to heat the thermos directly to have the structure of the thermos to increase the temperature of the contents will be.

In another embodiment of the present invention, the lower portion of the endothelium is characterized in that it is provided with a heating means using a heating wire, a thermal thin film, or a PTC heater.

For reference, a PTC heater is a barium titanate-based ceramic semiconductor widely used as an electric heating element using a PTC thermistor. PTC heater has a rapid increase in resistance value above a certain temperature, so if the PTC heater generates heat through electricity, the resistance increases rapidly above a certain temperature, so the PTC heater itself restricts the current, despite the fluctuation of outside temperature or power voltage. The temperature is almost constant. It is a self-regulating heater that combines the three functions of a heating element, a temperature sensor, and a power controller and does not worry about overheating. It is widely applied to dryers, warmers, and heaters.
