Abstract
The utility model discloses a double-layer sealing sanitary bottle cap structure which comprises a bottle opening and a bottle cap. A sealing ring at the top of the bottle cap is closely combined with the upper edge of the bottle opening to form a first sealing position. A sealing ring below a bottle cap extending part is closely combined with a stop plate to form a second sealing position. The vertical distance between the sealing ring at the top of the bottle cap and the sealing ring of the bottle cap extending part is equal to the vertical distance between the upper edge of the bottle opening and the stop plate. Threads of the bottle opening and the bottle cap are arranged inside a sealing cavity formed by the first sealing and the second sealing. According to the double-layer sealing sanitary bottle cap structure, the connecting threads are designed to be arranged inside the sealing cavity so that the threads of the bottle opening can be prevented from being polluted by the outside.
Description
Technical field
The utility model belongs to the articles for daily use field, relates to a kind of sanitary bottle cover, especially a kind of double-layer seal sanitary bottle cover.
Background technology
Present bottle cap sealing is all the individual layer sealing, and bottleneck outside screw part directly contacts with outside air, easily is subject to extraneous pollution.External thread of bottleneck part as beverage bottle is the lip that will contact the people having a drink, but easily is subject to the pollution of bacterium and objectionable impurities in the external thread of bottleneck part, brings harm for people's health.
Summary of the invention
The problem of polluting in order to solve the bottleneck outside, specially design and have antipollution Bottle cap structure.
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of double-layer seal sanitary bottle cover structure is provided, and comprises bottleneck and bottle cap, it is characterized in that: described bottleneck bottom is provided with baffle plate; Described bottle cap top inner plane is provided with bottle cap top seal ring, and the bottle cap bottom stretches out, and the bottom of bottle cap extension is provided with seal ring, and the vertical distance between the seal ring of top and bottom equates with the vertical distance between baffle plate with bottleneck.When bottle cap was tightened, two-layer seal ring all and bottle sealing.
Described double-layer seal, partly be arranged on whorl of bottleneck in the annular seal space of double seal formation.
The beneficial effects of the utility model are, connecting thread is designed in annular seal space, make the bottle neck threaded portion avoid outside contamination.
Description of drawings:
