High-sealing-performance vaccine glass bottle

Abstract

The invention discloses a high-sealing-performance vaccine glass bottle, and belongs to the technical field of vaccine glass bottles. An embedding part and an elastic sealing bag which are matched with each other are additionally arranged, during installation, gas is guided into a refrigeration cavity through a gas pipe, the gas is pressed into a gas guide cavity through a circulation hole, the elastic sealing bag and a magnetic extrusion part are synchronously expanded outwards under gas extrusion, the magnetic extrusion part plays an elastic supporting role on the elastic sealing bag, meanwhile, a magnetic attraction layer is used for carrying out magnetic attraction on an elastic magnetic ring, so that the elastic sealing bag is attached to a sealing gasket, the sealing performance of the joint of the elastic sealing bag and the sealing gasket is improved, the stability of the concave connection between a bottle plug and the embedding part is improved, the bottle plug is not prone to being separated from a bottle opening, a semiconductor refrigeration piece is used for refrigeration, and the circulating gas flow is used for low-temperature transmission in the bottle body, so that a low-temperature environment is provided for the vaccine; and in addition, when the refrigeration environment of the bottle body is damaged, the thermal expansion gas in an early warning pipe is thermally expanded to extrude and trigger a contact piece type high-temperature early warning piece, so that high-temperature early warning is realized.

Description

technical field [0001] The invention relates to the technical field of vaccine glass bottles, in particular to a high-tightness vaccine glass bottle. Background technique [0002] Vaccine glass bottles are made of borosilicate glass with high boron content, colorless transparent and brown transparent, low expansion coefficient, not easy to break, have good water resistance on the inner surface, and good compatibility with liquid medicine. It has good acid resistance, alkali resistance, freezing resistance and heat resistance. [0003] The existing new type of vaccine glass bottle has a relatively simple structure. The bottle mouth is only sealed by a simple bottle stopper, and the connection between the bottle stopper and the bottle body is realized only by the sliding action of the bottle stopper. On the one hand, it is impossible to ensure the complete sealing of the joint And make the vaccine loaded in the bottle free from pollution, on the other hand, this simple embedd...

Problems solved by technology

[0003] The existing new type of vaccine glass bottle has a relatively simple structure, and the bottle mouth is only sealed by a simple bottle stopper, and the connection between the bottle stopper and the bottle body is realized only by the sliding action of the bottle stopper. This makes the vaccine loaded in the bottle free from contamination. On the other hand, this simple embedded connection makes it difficult to ensure that the bottle stopper does not detach from the bottle body under external environmental factors, so it is difficult to meet the complex use environment.
