Description
Technical Field
The utility model relates to a volatile screw thread mouth reagent bottle lid of anti-solvent.
Background
Organic solvents are reagents commonly used in the chemical field and are difficult to store due to their high volatility. At present, screw glass reagent bottles commonly use two different bottle caps inside and outside simultaneously when sealing the bottleneck. Wherein the outer bottle cap is a threaded cap, and the mouth of the reagent bottle is sealed by screwing; the inner bottle cap is a thread-free direct insertion type bottle cap and is directly inserted into the mouth of the reagent bottle.
Because the inner bottle cap is a thread-free direct insertion type bottle cap and can be directly inserted into the mouth of the reagent bottle, the upper edge of the bottle cap is narrow and is tightly attached to the mouth of the reagent bottle when the inner bottle cap is taken out, so that the force-applying parts are few, the inner bottle cap is difficult to take out, and the inner bottle cap is usually required to be tilted by means of a tool and. When the use frequency is more, the inner bottle cap of the tool which is continuously tilted can be damaged, and the sealing performance is affected. Therefore, the problem that the inner bottle cap is difficult to take out and the inner bottle cap is easy to damage to influence the sealing performance exists when the inner bottle cap and the outer bottle cap are used for sealing the screw reagent bottle.
In order to solve the problem that the inner cup exists when using two above-mentioned sealed lids, the utility model provides a volatile screw thread mouth reagent bottle lid of anti-solvent can conveniently realize the operation that the bottle lid was screwed and was taken off to have the function of effective sealed volatile solvent.
Disclosure of Invention
The utility model discloses aim at: the utility model provides a screw thread reagent bottle lid that solvent volatilization was prevented to the problem that the sealed screw thread reagent bottle of two inside and outside different bottle lids had the interior bottle lid and takes out the difficulty, interior bottle lid easily receives destruction and influence the leakproofness.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a threaded reagent bottle cap capable of preventing solvent volatilization comprises a cap body 1 and a hollow sealing circular truncated cone 2, wherein the cap body 1 consists of a cap top 3 and a cap side wall 4, and a thread 5 is positioned on the inner side of the cap side wall 4; the upper top end of the hollow sealing circular truncated cone 2 is internally connected to the inner side of the cover top 3, so that the hollow sealing circular truncated cone 2 and the cover body 1 form a whole, wherein the hollow sealing circular truncated cone 2 is formed by combining an upper hollow sealing circular truncated cone 6 and a lower hollow sealing circular truncated cone 7, and the middle part of the hollow sealing circular truncated cone is not partitioned.
Particularly, the reagent bottle cap is matched with a threaded reagent bottle, and the lower hollow sealing circular table 7 is matched with the mouth of the threaded reagent bottle.
in particular, the angle α of the upper hollow sealing cone 6 ranges from 45 ° to 60 °, and the angle β of the lower hollow sealing cone 7 ranges from 75 ° to 85 °.
Particularly, the hollow sealing circular truncated cone 2 is made of polytetrafluoroethylene, wherein the thickness of the upper hollow sealing circular truncated cone 6 is 0.8mm to 1.0mm, and the thickness of the lower hollow sealing circular truncated cone 7 is 0.4mm to 0.6 mm.
The utility model has the advantages that:
1) the utility model has the advantages of simple structure and convenient operation;
2) the utility model discloses have the function of effective sealed volatile solvent.
