Problems solved by technology

Moreover, since there is no buffering substance filled between the bottle liner and the shell, when the thermos bottle is hit, the bottle liner is easy to break, which has certain dangers.

Embodiment Construction

[0021] The specific implementation of the invention will be further described below in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, a thermos bottle includes a shell 1, a bottle liner 2, an inner bottle cap 3, and an outer bottle cap 4; the material of the shell 1 is metal or plastic; the bottle liner 2 is installed in the inside of the shell 1 ; Between the bottle liner 2 and the shell 1, polyurethane foam is formed to form a polyurethane insulation layer 5; the polyurethane heat preservation layer 5 has an excellent heat preservation effect, and it is filled between the bottle liner 2 and the shell 1 time, slowing down the speed of heat diffusion from the bottle liner 2 to the outside, which can meet the needs of long-term heat preservation; at the same time, the material of the polyurethane insulation layer 5 is a flexible material, which has a buffering effect on external forces; when the thermos bottle is subjected to external forces Wh...

Abstract

The invention discloses a thermos bottle, which comprises a shell, a bottle liner, an inner bottle cap and an outer bottle cap; the bottle liner is installed inside the shell; the space between the bottle liner and the shell is formed by polyurethane foaming Polyurethane insulation layer; the inner bottle cap is covered on the bottleneck of the bottle liner, and is threadedly connected with the bottle liner; the inside of the inner bottle cap is provided with a vacuum layer, between it and the top of the bottle liner An elastic sealing ring is provided; the outer bottle cap covers the outer side of the inner bottle cap and is threadedly connected with the top of the shell; the present invention is provided with various heat preservation structures, which have a good heat preservation effect; in addition, the present invention also has the advantages of simple structure , with the advantage of being safe to use.

Description

technical field [0001] The invention relates to living utensils, in particular to a thermos bottle. Background technique [0002] In daily life, people often use vacuum flasks to store boiled water. Common vacuum flasks generally consist of a shell, a bottle liner, a cork and an outer cover. For vacuum flasks, people mainly pay attention to its thermal insulation effect and safety. There are two main factors that affect the thermal insulation effect of the thermos bottle, one is the tightness between the cork and the bottle liner, and the other is the heat leakage speed of the bottle liner itself. In the prior art, the cork of the vacuum flask is generally a wooden block with a conical structure. After long-term use, the soft plug is easily deformed in a humid steam environment, destroying the sealing structure between it and the bottle liner, causing the thermos bottle to lose its thermal insulation performance, and is often undetectable, affecting the normal supply of h...
