Sealing structure of bottle opening of in vitro diagnostic reagent bottle

Abstract

The invention discloses a sealing structure of a bottle opening of an in vitro diagnostic reagent bottle. The sealing structure comprises a reagent bottle, wherein a bottle nozzle is arranged on the reagent bottle, the bottle nozzle is in fit connection with a bottle cap, the bottle nozzle is provided with external threads, internal threads are arranged in the bottom cap, a sealing ring which fitswith the inner wall of the bottle nozzle is also arranged in the bottle cap, when the bottle nozzle is tightly fitted with the bottle cap, the top of the bottle nozzle tightly fits with inner top endof the bottle cap, and the bottle nozzle and the bottle cap are made of different materials; through the above structure design as well as the screw sealing, sealing ring sealing and fit sealing of the bottle nozzle and the top end of the bottle cap, the sealing of the reagent bottle is further strengthened, and meanwhile, the risk of bottle cap loosening caused by the internal stress of the bottle nozzle and the bottle cap is reduced by designing different materials of the bottle nozzle and the bottle cap.

Description

technical field [0001] The invention relates to a bottle mouth sealing structure of an in vitro diagnostic reagent bottle. Background technique [0002] At present, the reagent bottle and bottle cap on the market are sealed by screw locking, and the reagent bottle and bottle cap are made of the same material, specifically PP material, and this traditional sealing structure has the risk of leakage. At the same time, there is also a risk of leakage due to the release of internal stress in the bottle cap and the reagent bottle, which causes the thread to loosen and rebound. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the purpose of the present invention is to provide a bottle mouth sealing structure for in vitro diagnostic reagent bottles, specifically through the different material design of the reagent bottle and the bottle cap and the three sealing designs of the reagent bottle and the bottle cap to strengthen the reagent bo...
