Anti-volatility container for small packaged chemical reagents

Abstract

The invention provides packaging containers, in particular to an anti-volatilization container for small packaged chemical reagents. An expansion neck tube (5) is arranged on the upper portion of a tube (8) and fixed into a bottle opening (4) of a bottle body (9). A cross-shaped plate (3) is arranged on the upper portion of the interior of the expansion neck tube. The upper end of a connecting rod (7) is connected with the cross-shaped plate. The upper end and the lower end of a spring (6) abut against the lower surface of the cross-shaped plate and a step (16) formed between the lower end of the expansion neck tube and the tube. An end cap arranged at the lower end of the connecting rod blocks a lower opening of the tube. After a bottle cap (2) is connected with the bottle opening of the bottle body, a pressure column (1) arranged on the upper bottom of the interior of the bottle cap compresses the cross-shaped plate to enable the end cap to leave the lower opening of the tube. According to the anti-volatilization container for the small packaged chemical reagents, the chemical reagents in the bottle body are sealed through the end cap at the lower end of the tube, and contact between the chemical reagents and air is effectively reduced.

Description

[0001] 【Technical field】 [0002] The invention relates to a packaging container, in particular to a small package chemical reagent anti-volatility container. [0003] 【Background technique】 [0004] It is known that chemical reagents are relative standard substances for chemical research and component analysis, and are an important condition for scientific and technological progress. Chemical reagents are widely used in the synthesis, separation, qualitative and quantitative analysis of substances. It can be said that chemical work The eyes of the patient are inseparable from chemical reagents in the daily work of factories, schools, hospitals and research institutes; when chemical reagents are used, some will volatilize when they meet the air, some chemical reagents will deteriorate when they meet the air, and some will When the medium content reaches a certain value, "high concentration" can cause mild irritation of the eyes and respiratory mucosa, anesthesia, and even loss ...

AI Technical Summary

Problems solved by technology

Can cause mild dermatitis; however, these chemical reagents are usually packaged in bottles, and each time the bottle is opened and the chemical reagent is poured out, the reagent in the bottle will be exposed to air and evaporate in large quantities, on the other hand, it will cause the deterioration of the chemical reagent
