With the continuous improvement of people's requirements for the quality of life, the types of thermos bottle are increasing with people's consumption demand. It is improved and innovated in the aspects of appearance design, functional style, etc., and even divided into student type, outdoor type, office type, etc. student type thermos bottle is one of them.
In a broad sense, the thermos bottle uses the vacuum insulation layer to extend the heat loss time. The inner cup can also block the heat transfer to achieve the purpose of heat preservation. The fundamental difference lies in the design of appearance and function. The student type thermos bottle is generally in the shape of straight cylinder, the upper part of cup cover is relatively smooth, and the volume of bottle body is smaller than that of outdoor use, so it can be put into bag by students.
Because the students have to take nearly 8 hours of courses, the student type thermos bottle must be sealed to prevent water leakage, so as to avoid wetting the books, so as to well block the heat loss, and the insulation effect will last for more than 8 hours.
In life, the common capacity of students' thermos bottle is about 300ml to 500ml. The disadvantage is that it is difficult to clean the inside of the cover, easy to produce scale and bacteria, which is not conducive to health. This is the common fault of the thermos bottle. Therefore, we should pay more attention to cleaning at ordinary times, and do not pack carbonated drinks, so as to prevent the release of harmful substances from endangering human health.
