Filed: 2019-12-04
Abstract: The present invention relates to a thermos bottle capable of keeping hands warm to maintain the warmth of the user's hands directly by improving the conventional thermos bottle, which has existed to keep the contents warm. The present invention is to solve the problem that the existing thermos bottle cannot maintain the warmth of the hands holding the thermos bottle by attaching gloves (10) to an outer wall (11) of the thermos bottle. If gloves are attached to the thermos bottle, the user can maintain the warmth of the hands holding the thermos bottle without the need for an additional glove. As it can be seen in a figure 1, a rubber band (16) is attached to a wrist part of the gloves to closely contact the wrist and the gloves for preventing cold air from being penetrated into the gloves. In addition, as it can be seen in a figure 3, when the user does not use the gloves, the gloves are wrapped around the outer wall of the thermos bottle with a string (14) using snap buttons (12, 13) not to disturb the user. Accordingly, the user can expect the effect of maintaining the warmth of the hands and preventing frostbite.
