Problems solved by technology

[0003] 1) In the laboratory, the organic solvent in the reagent bottle is poured out, and the liquid in the beaker and measuring cylinder is poured out. Due to the large mouth, the flow rate cannot be well controlled. The inclination angle is closely related to the liquid volume in the solvent bottle, and it is easy to sprinkle
In addition, during the pouring process, due to the large surface area of ​​the organic solvent exposed to the air, the solvent volatilizes more, which is easy to injure the operator and pollute the environment
[0004]2) Washing bottles commonly used to hold water and ethanol need to be squeezed by hand when washing instruments, and it is difficult to control the flow rate. The threaded joint gradually becomes loose, and the elasticity of the washing bottle gradually decreases, which affects future use

Embodiment 1

[0035] Embodiment 1 Simple and easy bottle stopper for pouring liquid

[0036] See attached figure 1 , 2 , 3, where A is the plug body, and B1 and B2 are the pipelines. B1 and B2 communicate with the bottom of the plug body, and extend in two different directions outside the plug body. The diameter of the tip of B1 is thinner, and the diameter of the tip of B2 is slightly thicker. The preparation material is plastic, and the straight diameter of the lower part of the plug body A Not the same, the diameter of the lower edge is slightly smaller, and the diameter of the middle is slightly larger.

[0037] This bottle stopper can directly plug the bottle body Y such as reagent bottles during operation. The elasticity of the plastic material makes the bottle stopper not easy to fall off. According to the flow rate and flow rate of the poured liquid, select a pipeline to align with the other bottle body and slowly Controlled inclination for pouring. After the pouring is complete...

Embodiment 2

[0038] Example 2 Ground-mouth stopper for pouring liquid

[0039] See attached Figure 4 , where A is the ground plug body, A1 is the outer ground part of the ground plug body, B11 is the outer ground part of the pipeline B1, B21 is the outer ground part of the pipeline B2, C11 is the ground small cover C1 C21 is the grinding part of the small cover C2, C11 is matched with B11, C21 is matched with B21, B1 and B2 communicate with the bottom of the plug body, and extend in two different directions outside the plug body , the tip diameter of B1 is thinner, and the tip diameter of B2 is slightly thicker. The preparation material of this product is glass.

Embodiment 3

[0040] Example 3 A screw cap for pouring liquid formed by combining two materials and three components

[0041] See attached Figure 5 , 6 as shown, Figure 5 The B1 and B2 pipelines in the circuit are not bent, so that it is convenient to put A2 on A1, and then bend B1 and B2. Figure 6 As shown, A1, A2, B1, and B2 are combined to form a screw cap, and a flange gasket A3 is used to cover the screw bottle body Y, and the purpose of dumping can be realized after tightening.

Abstract

The invention relates to a bottle cap and bottle stopper combination for pouring liquids such as organic solvents, acid and alkali in common use in laboratories. The bottle cap and bottle stopper combination at least comprises a cap body or stopper body, a liquid outlet tube and an air inlet tube. When being applied for pouring the liquids, the bottle cap and bottle stopper combination is quite convenient to operate, directly combined with a bottle body and free of liquid spillage in the pouring process, and surface area of the liquids exposed to air is extremely small; when the poured liquids are volatile organic solvents, solvent evaporation is little, operators cannot not get injured easily, the environment is not easy to damage, and acid and alkaline solutions are more safely poured; great convenience is brought to the operators.

Description

technical field [0001] The invention relates to an instrument commonly used for liquid pouring in the fields of chemical industry, medicine, food, etc., and in particular to a bottle cap and a bottle stopper for liquid pouring. Background technique [0002] Liquid pouring is one of the commonly used operating units in the fields of chemical industry, medicine, food, etc., such as pouring water and organic solvents in the laboratory. The commonly used pouring methods and their disadvantages are as follows: [0003] 1) In the laboratory, the organic solvent in the reagent bottle is poured out, and the liquid in the beaker and measuring cylinder is poured out. Due to the large mouth, the flow rate cannot be well controlled. The inclination angle is closely related to the liquid volume in the solvent bottle, and it is easy to poured. In addition, during the pouring process, due to the large surface area of ​​the organic solvent exposed to the air, the solvent volatilizes more, ...
