Abstract
The invention provides a sealed bottle cap which comprises a bottle cap body and a sealed lining arranged in the bottle cap body, wherein the bottle cap body comprises a side wall and a top wall, and the side wall is connected with the periphery of the top wall; the sealing liner comprises a sealing ring body, an extension ring and a sealing top, wherein the sealing ring body is a hollow circular ring, the sealing top is arranged on the sealing ring body and is connected with the whole sealing ring body, one side, far away from the sealing ring body, of the sealing top is fixedly connected with the bottle cap body, the extension ring is arranged on the sealing ring body, and the extension direction of the extension ring is perpendicular to the sealing top. The bottle cap body with the equal hand screw thread in sealed inside lining inboard can realize treating the double-deck sealed of lid bottle, even simultaneously the bottle cap body or sealed inside lining damages, and another can realize sealed function as usual.
Description
Technical Field
The invention relates to a bottle cap, in particular to a sealed bottle cap.
Background
In production and life, a large number of articles need to be stored in a sealed manner, such as food, medicines and the like, the storage tightness has great influence on the validity period and efficacy, and when people use bottled products, the bottle caps can be pried and loosened by a tool due to too tight bottle caps, so that the bottle caps cannot be reused, and certain troubles are brought to storage and use of the products by users.
Disclosure of Invention
The invention aims to provide a sealed bottle cap which has good sealing performance and does not influence the use by the tilting or damage of the side wall of the edge.
The invention provides a sealed bottle cap which comprises a bottle cap body and a sealed lining arranged in the bottle cap body, wherein the bottle cap body comprises a side wall and a top wall, and the side wall is connected with the periphery of the top wall; the sealing liner comprises a sealing ring body, an extension ring and a sealing top, wherein the sealing ring body is a hollow circular ring, the sealing top is arranged on the sealing ring body and is connected with the whole sealing ring body, one side, far away from the sealing ring body, of the sealing top is fixedly connected with the bottle cap body, the extension ring is arranged on the sealing ring body, and the extension direction of the extension ring is perpendicular to the sealing top.
Preferably, the depth of the sealing liner is less than the depth of the bottle cap body.
As a preferable scheme, the inner side of the part of the side wall of the bottle cap body, which exceeds the extension ring, is provided with a connecting thread for connecting with a bottle mouth to be covered.
Preferably, the extension thread identical to the connecting thread is arranged on the inner side of the extension ring, and the extension thread is connected with the connecting thread.
Preferably, the inner side of the extension ring is tangent to the outer side of the sealing ring body.
Has the advantages that: the sealing bottle cap provided by the invention comprises a bottle cap body and a sealing lining arranged in the bottle cap body, can seal a bottle to be capped in two layers, has good sealing performance, and can be still connected with the bottle mouth of the bottle to be capped when the bottle cap body is damaged, so that the sealing function is realized.

Fig. 1 is a schematic structural view of a sealed bottle cap provided by the present invention.
Detailed description of the preferred embodiments
The embodiments described below are only a part of the embodiments of the present invention, and not all of them. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the present invention provides a sealed bottle cap, which includes a bottle cap body and a sealing liner disposed in the bottle cap body.
The bottle cap body comprises a side wall 11 and a top wall 12, and the side wall 11 is connected with the periphery of the top wall 12; the sealing liner comprises a sealing ring body 21, an extension ring 22 and a sealing top 23, wherein the sealing ring body 21 is a hollow circular ring and plays a role in sealing during use, the sealing top 23 is arranged on the sealing ring body 21 and is connected with the whole sealing ring body 21, one side, far away from the sealing ring body 21, of the sealing top 23 is fixedly connected with the bottle cap body, the extension ring 22 is arranged on the sealing ring body 21, and the extension direction of the extension ring 22 is perpendicular to the sealing top 23.
The depth of the sealing lining is smaller than that of the bottle cap body, the inner side of the part, exceeding the extension ring 22, of the side wall 11 of the bottle cap body is provided with a connecting thread 111 for being connected with a bottle opening to be covered, the inner side of the extension ring 22 is provided with an extension thread 221 which is the same as the connecting thread 111, the extension thread 221 is connected with the connecting thread 111, and the inner side of the extension ring 22 is tangent to the outer side of the sealing ring body 21.
When the sealing bottle cap is used, the connecting threads 111 and the extending threads 221 on the bottle cap body and the sealing lining in the sealing bottle cap provided by the invention are tightly covered corresponding to the threads at the bottle mouth of the matched bottle to be capped, the bottle cap body and the sealing lining are sealed in a double-layer mode, meanwhile, the sealing performance of the sealing bottle cap is improved due to the existence of the sealing ring body 21, and the sealing bottle cap provided by the invention has absolute sealing performance. When one of the bottle cap body or the sealing lining is damaged, the use and the performance of the other one are not greatly influenced, and the bottle cap can still be continuously used.
The above disclosure is only one preferred embodiment of the present invention, and certainly should not be taken as limiting the scope of the invention, which is defined by the claims and their equivalents.
