Description

Insulation with multiple sealed thermal insulation structure and easy-to-assemble glass liner bottle

The present invention relates to the technical field of thermos, and in particular to a thermos bottle having a multi-seal insulation structure and an easy-to-remove glass liner.

At present, the thermos bottle on the market mainly includes a bottle body and a bottle cap, and a sealed insulation space is formed through the thread connection between the bottle body and the bottle cap, and the quality of the existing thermos bottle is uneven, which often fails to achieve the effect of heat preservation. The heat loss in the bottle body is too fast, and there are problems such as poor sealing. Secondly, in order to enhance the thermal insulation performance, the traditional thermal insulation bottle is connected by welding between the inner and outer walls of the bottle. In actual use, once the inner wall is damaged, the thermal insulation bottle loses the thermal insulation performance, and the thermal insulation cannot be changed by replacing the inner wall. The bottle continues to be used. To this end, there is a need for a thermos bottle that is more leak-tight, more insulative, and more reliable, as well as a glass liner that can be replaced or removed.

The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a thermos flask having a multi-seal insulation structure and an easy-to-detach glass liner.

In order to achieve the above object, the invention provides a thermos bottle with multiple sealing and heat insulating structures and an easy-to-detach glass liner, which comprises a bottle cap, a fixed cover, a sealing plate, a sealing ring, a glass liner and a bottle body. The outer side surface and the inner side surface of the bottle body mouth are respectively formed with a bottle body outer thread and a bottle body inner thread, wherein the outer thread of the bottle body and the inner thread of the bottle body respectively are on the inner side surface of the bottle cap Forming a cap screw and a glass liner threaded surface on the outer side of the glass liner; the sealing ring is sleeved on the outer side surface of the glass liner, wherein when the bottle body is coupled with the glass liner, The lower surface of the sealing ring is in contact with the edge of the bottle mouth; the fixing cover is coupled with the top of the inner side of the bottle cap, and the water sealing piece is set outside the fixing cover, wherein when the bottle body is coupled with the bottle cap, The sealing piece is sealed with the bottle mouth of the glass liner.

In an embodiment of the present invention, the top of the inner side of the cap is formed with a fixing boss, and the fixing boss is coupled with the fixing slot formed on the fixing cover.

In an embodiment of the present invention, a plurality of convex bone strips are formed on the quasi-outer surface of the sealing water.

In an embodiment of the present invention, the inner side of the water sealing sheet is formed with an undercut that cooperates with the top end of the fixing cover.

In an embodiment of the present invention, the bottle body is provided with a vacuum hollow interlayer.

The present invention adopts the above-mentioned scheme, and has the beneficial effects that the bottle cap, the fixed cover, the sealing water piece, the sealing ring, the glass liner and the bottle body constitute a thermos sealing structure; the glass liner and the bottle body are fixed by a screw connection And by pressing the sealing ring up and down, the glass liner is easily replaced and the sealing effect between the glass liner and the bottle body is achieved; the glass liner mouth and the sealing water piece cooperate to prevent leakage and sealing; Through the mutual connection between the three parts of the bottle cap, the fixed cover and the sealing plate, and the vacuum hollow interlayer of the bottle body, the heat exchange between the heat in the glass liner and the outside air is isolated, thereby further improving the heat preservation performance of the thermos bottle. Secondly, because the glass liner is easy to replace and remove, the thermos bottle is more durable, and the glass liner can be removed and the bottle body can be used directly.

In order to make any skilled person understand the technical content of the present invention and implement it according to the content, patent application scope and drawings disclosed in the specification, any skilled person can easily understand the purpose and advantages related to the creation. Therefore, the detailed features and advantages of the present invention will be described in detail in the embodiments.

The present invention will be further described below in conjunction with specific embodiments.

Referring to FIG. 1 to FIG. 11 , in the embodiment, a thermos bottle having multiple sealing and heat insulating structures and an easy-to-detach glass inner tank includes a bottle cap 2, a fixing cover 5, a sealing water piece 6, and a sealing. Ring 4, glass liner 3, bottle body 1; the outer side surface and the inner side surface of the bottle body 1 are respectively formed with a bottle body outer thread 11 and a bottle body inner thread 12, wherein the bottle body outer thread 11 and the bottle The body opening thread 12 is threadedly connected with the bottle screw 22 formed on the inner side of the bottle cap 2 and the glass liner thread 31 formed on the outer side of the glass liner 3, and the sealing ring 4 is sleeved in the glass. On the outer side of the bladder 3, wherein the bottle body 1 is screwed to the glass liner 3, the lower side of the sealing ring 4 is in contact with the edge of the bottle body 1, and the sealing ring 4 is pressed up and down by the bottle body 1 and the glass liner 3 Achieve the sealing effect. A fixing boss 21 is formed on the top of the inner side of the cap 2, and the fixing cover 5 is provided with a fixing slot 51 which cooperates with the fixing boss 21; the sealing sheet 6 is set outside the fixing cover 5, wherein the sealing sheet 6 is inside An undercut 62 matching the top end of the fixing cover 5 is formed on the side surface, and the water sealing sheet 6 can be more firmly connected to the fixing cover 5 by providing the undercut 62, thereby preventing the sealing sheet 6 from falling and the sealing performance from being deteriorated. Case. A plurality of convex strips 61 are formed on the outer side surface of the sealing water piece 6. When the bottle body 1 is coupled with the bottle cap 2, the sealing water piece 6 is matched with the inner side surface of the glass bottle 3 bottle mouth, and is prevented by the sealing water piece 6 Leaking water and sealing effect with the glass liner 3, and providing a plurality of convex strips 61 to contact the inner side surface of the glass liner 3 to further improve the sealing between the sealing sheet 6 and the glass liner 3; 1 is provided with a hollow interlayer, and when the glass liner 3 is placed in the bottle body 1, the amount of liquid heat inside the glass liner 3 is reduced to be exchanged with the air outside the bottle body 1 through the bottle body 1, thereby reducing heat. loss. Through the composition of the above components and the mutual use, the thermos bottle has multiple sealing and heat insulating structures, thereby further improving the thermal insulation performance, reliability and sealing performance of the thermos bottle. Secondly, due to the easy-disassembly characteristics of the glass liner 3, the thermos bottle has the characteristics of replacing or removing the glass liner 3, thereby making the thermos bottle more durable, and at the same time, when the glass liner 3 is damaged and not replaced or When the glass liner 3 is not used according to its own needs, the glass liner 3 can be removed and the bottle 1 can be used directly.
