Small packaging barrel with volatilization preventing and sealed pouring structure

Abstract

The invention relates to a small packaging barrel, in particular to a small packaging barrel with a volatilization preventing and sealed pouring structure. An inner protruding ring (19) is arranged onthe lower portion of the inner wall of a bottle opening (17). The lower portion of the outer edge of a base plate (12) at a lower opening of an upper protruding ring (30) of an inner cover is pressedonto a step (18) formed on the upper surface of the inner protruding ring, and a lower protruding tube (26) is arranged on the lower surface of the base plate. The lower portion of a lifting tube (13) penetrates into the lower protruding tube. A sealing ring (27) is arranged on the outer edge of the lower end of the lifting tube, and a locking ring (33) is arranged at the upper end of the liftingtube. The upper end and the lower end of a spring (32) which is arranged on the lifting tube in a sleeving mode abut against the locking ring and the base plate correspondingly. Lower plates (25) arearranged on the lower portion of the inside of the lifting tube. Protruding bars are arranged on the upper surfaces of the lower plates. Pouring holes (14) are formed in the positions, located between gaps of the protruding bars, of the base plate. According to the small packaging barrel with the volatilization preventing and sealed pouring structure, the automatic sealing structure of the lifting tube is utilized, air contact in the filling process can be reduced, and the probability that chemical liquid charging stock makes contact with the air is effectively lowered.

Description

【Technical field】 [0001] The invention relates to a small packaging bucket, in particular to a small packaging bucket with a volatilization-proof and sealed pouring structure. 【Background technique】 [0002] It is known that various chemical reagents obtained during crude oil refining, among which chemical products such as butane, pentane, n-hexane, heptane, octane, petroleum ether, solvent oil and aromatic hydrocarbons need to be sold after production and acquisition, these products either have Volatile, flammable, explosive, or highly toxic; in view of this, it is necessary to use explosion-proof lighting and ventilation facilities in storage. It is even more forbidden to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials, and when filling, there will be leakage and splashing when the filling tube is inserted into the bottle mouth, so a large amount ...

AI Technical Summary

Problems solved by technology

The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials. When filling, there will be leakage and splashing when the filling tube is inserted into the bottle mouth, so a large amount of volatile gas accumulates in the air in the workshop, and more importantly, , for some high-purity products, once exposed to air for too long, the quality will decline
