Description

technical field [0001] The invention belongs to the field of daily necessities, and in particular relates to a thermos bottle with a cork that prevents falling. Background technique [0002] The thermos bottle is a daily necessities. There are shells made of bamboo strips, iron sheets, plastics, etc. on the outside, and bottle bladders are housed inside. The bottle liner is made of double-layer glass, the two sides of the interlayer are plated with silver, aluminum, copper and other metals, the middle is evacuated, and the bottle mouth has a stopper, which can maintain the temperature in the bottle for a long time. [0003] Because the general wooden bottle stopper is simply plugged in the mouth of the bottle, when people finish opening the boiled water and carry the boiled water back, the bottle body is in a tilted state, the gas in the thermos bottle is heated and collided, and in the process of walking, the thermos bottle shakes. It is easy to push out the bottle stopper...

Problems solved by technology

[0003] Because the general wooden bottle stopper is simply plugged in the mouth of the bottle, when people finish opening the boiled water and carry the boiled water back, the bottle body is in a tilted state, the gas in the thermos bottle is heated and collided, and in the process of walking, the thermos bottle shakes. It is easy to push out the bottle stopper, and if it is light, the bottle stopper will fall to the ground, and it will not be used immediately if it is polluted. After long-term use, the thermos bottle will have a thick layer of scale attached to the inner wall of the tank, which is not easy to clean.
