Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 to 3, in the inner plug structure provided in this embodiment, a first sealing ring 203, a plurality of second sealing rings 204, and a third sealing ring 205 are disposed on a central plug 202, and the diameter of the third sealing ring 205 is larger than the diameter of the second sealing ring 204.

Specifically, the central plug 202 when in use is located in the bottle neck 102, the top of the third sealing ring 205 is movably contacted with the bottle neck connecting inner surface 103, the third sealing ring 205 is used for being propped against the bottle neck connecting inner surface 103 after being inserted, so as to play a role in blocking the flow of liquid in the bottle body to the direction of one side of the bottle mouth, and as the third sealing ring 205 can block most of the liquid flowing towards the bottle mouth, the liquid pressure born by the first sealing ring 203 and the second sealing ring 204 is very small, thereby improving the sealing effect of the first sealing ring 203 and the second sealing ring 204.

The bottle is characterized in that a first through hole 207 is formed in one side, close to a bottle opening, of the central plug 202, the sealing plug 206 is matched with the first through hole 207, the central plug 202 is of a hollow structure, a second through hole 208 is formed in one side, far away from the bottle opening, of the central plug 202, liquid in a bottle can be poured out of the first through hole 207 from the second through hole 208 after passing through the hollow central plug 202, and during use, the sealing plug is locked through friction of the first sealing ring 203, the second sealing ring 204 and the third sealing ring 205, so that the plug stability is improved, and the falling risk of an inner plug structure body due to liquid pressure, false touch and other factors is reduced.

Further, the diameter of the second sealing ring 204 is greater than the inner diameter of the bottle mouth 102 by more than 1mm, the outer side of the second sealing ring 204 is in close contact with the inner side of the bottle mouth 102, the second sealing ring 204 is used for increasing the friction force between the central plug 202 and the inner side of the bottle mouth 102 to perform friction limitation, and meanwhile, the plurality of second sealing rings 204 also have the effect of multi-layer sealing shielding, so that the sealing performance of the inner side of the bottle mouth 102 is enhanced.

Further, the bottom of the central plug 202 is provided with a tapered structure 201, and the tapered structure 201 facilitates better insertion of the central plug 202 into the mouth 102.

Further, the first sealing ring 203, the second sealing rings 204 and the third sealing ring 205 are all made of environment-friendly elastic materials such as edible elastic silica gel rings or PP, and are used for ensuring the safety of the liquid in the bottle body 101.

The application method of the embodiment is as follows: when the bottle neck sealing device is used, when the central plug 202 is inserted into the bottle neck 102, the central plug 202 drives the third sealing ring 205 to be extruded with the inner side of the bottle neck 102, so that the third sealing ring 205 is deformed and moves into the bottle body 101, and under the action of self elasticity, the third sealing ring 205 rebounds and is attached to the nozzle body to be connected with the inner surface 103, so that preliminary sealing is realized. In actual use, when the bottle body is shaken, laid flat or put upside down, the third sealing ring 205 plays a role in blocking the flow of liquid in the bottle body to the direction of one side of the bottle mouth, and as the third sealing ring 205 can block most of the liquid flowing to the bottle mouth, the liquid pressure born by the first sealing ring 203 and the second sealing ring 204 is very small, so that the sealing effect of the first sealing ring 203 and the second sealing ring 204 is improved.

Meanwhile, the diameter of the second sealing ring 204 is 1-2mm larger than the inner diameter of the bottle mouth 102, meanwhile, when the central plug 202 moves downwards, the plurality of second sealing rings 204 are driven to be extruded into the inner side of the bottle mouth 102, multiple friction fixing is realized by using the tight friction force between the plurality of second sealing rings 204 and the inner side of the bottle mouth 102, meanwhile, when the central plug moves downwards, the first sealing ring 203 is driven to be pressed on the top of the bottle mouth 102, at the moment, the first sealing ring 203, the third sealing ring 205 and the plurality of second sealing rings 204 form multi-layer sealing, so that the plug tightness is improved, the risk of outward liquid seepage caused by shaking or false touch and other factors can be effectively reduced by using the multi-layer sealing, the plug stability is improved by using a mode of forming multiple friction locks by the plurality of second sealing rings 204, and the risk of falling off of an inner plug structure caused by liquid pressure or false touch and other factors is reduced; when it is desired to pour the liquid from the bottle, the liquid is poured out of the first through hole 207 by opening the sealing plug 206.

Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present utility model, and the present utility model is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present utility model has been described in detail with reference to the foregoing embodiments.
