Description

Technical Field

[0001] The utility model relates to the technical field of thermos bottles, in particular to a leak-proof shell of a thermos bottle. Background Art

[0002] A thermos bottle, simply put, is a water bottle that can keep water warm. It is usually a water container made of ceramic or stainless steel with a vacuum layer. It has a lid on the top and is tightly sealed. The vacuum insulation layer can delay the heat dissipation of the water and other liquids inside to achieve the purpose of keeping warm.

[0003] Most of the thermos bottles on the market currently use a metal shell with an insulation layer inside and a switch or screw cap on the top for easy opening and closing. Although the thermos shell can provide good insulation performance, the shell cannot ensure that the liquid is completely sealed. Due to problems such as shell collision, the insulation layer is prone to leakage. Moreover, the container is mostly filled with high-temperature water. When hot water leaks, it is easy to cause scalds to the user. For this reason, we propose a leak-proof shell for the thermos. Utility Model Content
