Embodiment Construction
[0016] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0017] Such as figure 1 As shown, a container for preventing the volatilization of chemical reagents includes a bottle body 1 and a cap body 2 that is threadedly connected to the opening of the bottle body 1 to match the opening, and also includes a sealing device that seals the opening of the bottle body 1 The opening of the bottle body 1 is in the shape of a cone with a small top and a large bottom. The sealing device includes a screw 3 whose thread runs through the top of the cover 2 vertically. The upper end of the screw 3 is located at the top of the cover On the upper part outside the body 2, a knob 4 is fixedly connected to the upper end of the screw rod 3, the lower end of the screw rod 3 is inside the openi...

The invention relates to a container capable of preventing a chemical reagent from volatilizing. The container comprises a bottle, a cover and a sealing device, wherein the cover is connected to the opening of the bottle in a threaded manner, the sealing device for sealing the opening comprises a screw, the thread of the screw vertically penetrates the top of the cover, a rotary knob is fixedly connected to the upper end of the screw, and a blocking piece is fixedly connected to the lower end of the screw; a rubber sealing plug slidably sleeves the part, between the blocking piece and the top of the cover, of the screw, the blocking piece can be driven to move upwards to squeeze the rubber sealing plug to allow the rubber sealing plug to expand to seal the opening of the bottle by rotating the rotary knob. The container has the advantages that the screw can be driven to move upwards by rotating the rotary knob, the blocking piece moves upwards and squeezes the rubber sealing plug along with the upward movement of the screw until the rubber sealing plug expands to tightly seal the opening of the bottle, the reagent in the bottle is prevented from being contact with air, and the volatilizing of the reagent is prevented.
Description
technical field [0001] The invention relates to the field of chemical instruments, in particular to a container for preventing chemical reagents from volatilizing. Background technique [0002] Many chemical reagents are extremely volatile solutions. For such extremely volatile solutions, they need to be kept in a sealed environment to prevent them from contacting with the air. At present, the easily volatile reagents are generally kept in common reagent bottles, and the solution in the reagent bottles is likely to volatilize due to poor sealing. Contents of the invention [0003] In summary, in order to overcome the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a container that prevents chemical reagents from volatilizing. [0004] The technical scheme of the present invention to solve the above-mentioned technical problems is as follows: a container for preventing the volatilization of chemical reagents, includi...
