Description

Special ware of covering that plays of impulse type reagent bottle inner cup

Technical Field

The invention relates to a cover opener, in particular to a special cover opener for an inner cover of a pulse type reagent bottle.

Background

Most liquid chemical reagent bottles in the market at present adopt bottle container to add the lid and store, and general bottle container includes enclosing cover and inner cup, and the inner cup is generally for the plastic construction of taking the shirt rim, mainly plays sealed effect. The inner cap is tightly matched with the bottle mouth, so that the bottle cap is difficult to open by bare hands. The flange outer diameter of the inner cap of the solution bottle is smaller than the outer diameter of the bottle mouth, the inner cap is mostly made of plastics and is difficult to open, and particularly, the inner cap of the bottle for containing hydrochloric acid and other volatile solutions can cause the pressure in the bottle to be reduced due to the volatilization of the solutions, so that the inner cap is difficult to open. In addition, for the bottles containing chemical solutions such as hydrochloric acid, sulfuric acid and the like which are placed for a long time, the inner caps of the bottles can be adhered to the bottle openings due to corrosion or solution crystallization, so that the bottles are not easy to open. Generally, a tool such as tweezers is used in a laboratory to clamp one corner of the flange of the inner cover, and then the inner cover is pulled open with force, so that the inner cover is damaged with great effort, and the solution in the reagent bottle is splashed easily in the moment when the inner cover is opened, thereby causing great threat to the personal safety of operators.
