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...
