In the middle is a double-layer glass bottle liner, and the space between the two layers is evacuated and silver-plated or aluminum-plated. The evacuated state can avoid heat convection, and the glass itself is a poor conductor of heat. The silver-plated glass can reflect the heat energy radiated from the inside of the container back.

[0003] However, for the existing glass thermos bottles, when pouring hot water into the thermos bottle, the hot water will directly contact the bottom of the glass thermos bottle, and the hot water cannot evenly preheat the inner liner of the thermos bottle, resulting in different local temperatures and causing the inner liner to crack.

[0008] Preferably, a water outlet is penetrated and opened on the internal thread cap, and the water outlet is communicated with the external thread port and the heat preservation glass inner liner; the diameter of the internal thread cap is smaller than the inner diameter of the sealing cover.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] With the overall setting of the utility model, during the process of pouring hot water into the heat preservation glass inner liner, the hot water can be evenly guided to the side wall of the heat preservation glass inner liner through the guiding mechanism, and the hot water can flow evenly along the side wall to the bottom of the heat preservation glass inner liner; in this way, the heat preservation glass inner liner can be evenly preheated, preventing the hot water from directly flowing to the bottom of the heat preservation glass inner liner; thus avoiding the heat preservation glass inner liner from cracking due to a large temperature difference, making the whole more safe and reliable during use.

The external thread port 2 is inside the external thread port two 6, and the height of the external thread port 2 is higher than that of the external thread port two 6 for disassembly and assembly of the diversion mechanism 7. The external thread port two 6 is fixedly connected to the external thread port 2. The diversion mechanism 7 is detachably and fixedly installed inside the heat-preserving glass inner container 1 through the external thread port 2 for filling hot water into the heat-preserving glass inner container 1. During the filling process, the hot water evenly flows slowly along the side wall of the heat-preserving glass inner container 1 to the bottom of the heat-preserving glass inner container 1, so as to achieve the overall preheating effect of the heat-preserving glass inner container 1. The external thread port two 6 is detachably and fixedly installed with a sealing cover 8 for sealing the external thread port two 6 to prevent heat loss of the heat-preserving glass inner container 1;

[0022] The diversion mechanism 7 includes a conical funnel 71, and a flexible hollow diversion disc 72 is fixedly installed at the conical end of the conical funnel 71. Through the arrangement of the flexible hollow diversion disc 72, when the flow rate of hot water inside the conical funnel 71 is small, the hot water flowing out from the diversion holes 73 can flow onto the flexible hollow diversion disc 72, and then flow onto the side wall of the heat preservation glass liner 1 through the flexible hollow diversion disc 72, avoiding a large amount of hot water flowing directly to the bottom of the heat preservation glass liner 1. The flexible hollow diversion disc 72 communicates with the conical funnel 71 to facilitate filling hot water into the heat preservation glass liner 1 through the conical funnel 71, and at the same time, after filling, prevent hot water from remaining inside the conical funnel 71; a number of diversion holes 73 are evenly distributed and penetrated through the circumferential surface of the conical funnel 71, so that during the process of filling hot water into the heat preservation glass liner 1, the hot water can be evenly discharged onto the side wall of the heat preservation glass liner 1 through the diversion holes 73, and then the hot water can evenly flow along the side wall of the heat preservation glass liner 1 to the bottom of the heat preservation glass liner 1 to achieve a preheating effect, thereby avoiding a large temperature difference in local areas of the heat preservation glass liner 1 and preventing the heat preservation glass liner 1 from cracking. And the other end of the conical funnel 71 is fixedly installed with an internal thread cap 74 for disassembly and assembly with the external thread port 2; the inside of the internal thread cap 74 is threadedly connected to the outside of the external thread port 2; the conical funnel 71 and the flexible hollow diversion disc 72 extend into the heat preservation glass liner 1 through the external thread port 2; the diameter of the flexible hollow diversion disc 72 is larger than the inner diameter of the external thread port 2, and the diameter of the flexible hollow diversion disc 72 is smaller than the inner diameter of the heat preservation glass liner 1; it should be noted that both the conical funnel 71 and the internal thread cap 74 are made of food-grade stainless steel materials, and the flexible hollow diversion disc 72 is made of food-grade high-temperature resistant silica gel.

[0023] A cavity 31 is provided on the shell of the rubber protective shell 3, which can have a good buffering effect when subjected to external pressure or dropped on the ground, preventing the heat preservation glass liner 1 from cracking.

[0024] A number of anti-slip protrusions 5 are evenly distributed and fixedly installed on the circumferential surface of the rubber protective shell 3 to increase the friction with the hand during the use by the user and prevent slipping. And a transparent area 4 for viewing the water volume is provided on the surface of the rubber protective shell 3, and the length of the transparent area 4 is the same as the length of the heat preservation glass liner 1 to facilitate the user to view the water volume in the heat preservation glass liner 1.

[0025] A water outlet 75 is penetrated through the internal thread cap 74 to allow the hot water in the heat preservation glass liner 1 to flow out for drinking. At the same time, through the arrangement of the water outlet 75, the air convection inside the heat preservation glass liner 1 can be reduced, making the heat preservation glass liner 1 have a better heat preservation effect, and the water outlet 75 communicates with the external thread port 2 and the heat preservation glass liner 1; the diameter of the internal thread cap 74 is smaller than the inner diameter of the sealing cover 8.
