Description

Large-package liquid chemical reagent packaging bottle convenient to take

Technical Field

The utility model relates to a big packing liquid chemical reagent packing bottle convenient to take.

Background

Liquid reagents are commonly used in chemical experiments, the liquid reagents for commercial laboratories are usually contained in a glass bottle with a narrow opening, and reagents of chromatographic grade are mostly contained in a large-package glass bottle with 4L. In general, a large package of liquid reagent is taken out or directly poured out by a pipette or other tool.

However, the operation of taking the reagent by extending the tool into the liquid surface risks contaminating the whole bottle of reagent; direct pouring often causes liquid to spill due to the inconvenient operation that the bottle is big, and the volume of pouring is not good to be held simultaneously, easily causes the waste.

Therefore, the technical personnel in the field are dedicated to develop a large package liquid chemical reagent package bottle which is convenient to take.

In view of the above-mentioned defects in the prior art, the technical problem to be solved in the utility model is to provide a big packing liquid chemical reagent packing bottle convenient to take.

In order to achieve the purpose, the utility model provides a large-package liquid chemical reagent packaging bottle convenient to take and use, which comprises a bottle body and a bottle cap, wherein the upper end of the bottle body is provided with a bottle shoulder, the outer side of the bottle shoulder is provided with an outer ground, the bottle cap is a tubular structure with two open ends, and the inner side of the lower end of the bottle cap is provided with an inner ground matched with the outer ground of the bottle shoulder;

the bottle is characterized in that a drainage tube is arranged in the bottle shoulder, the upper end of the drainage tube extends out of the bottle shoulder, the lower end of the drainage tube extends into the bottle shoulder and transversely extends to be connected with the bottle shoulder, and a leak hole is formed in the joint of the drainage tube and the bottle shoulder.

Preferably, the upper end of the drainage tube is provided with a drainage notch.

Preferably, the leak hole transversely faces the drainage notch.

Preferably, the bottle body is provided with first scale marks, and the bottle cap is provided with second scale marks.

Preferably, the bottle body is provided with a handle.

Preferably, the handle is transversely aligned with the first graduation mark.

Preferably, the drainage tube is integrally arranged on the bottle shoulder.

The utility model has the advantages that: the utility model discloses in the big packing liquid chemical reagent packing bottle convenient to take, the drainage tube is convenient for the outflow of reagent, the small opening can be with when empting liquid stay in the liquid guide back bottle of drainage tube outer wall, avoided liquid reagent to flow along the body outer wall and erode the label bottle and the poisonous and harmful reagent of outflow probably causes the experimenter incident, and the bottle lid passes through the whole leakproofness that the ground realized with the body, avoided using other materials such as plastics or rubber and liquid reagent to take place the possibility of interact.
