Description

Technical Field

[0002] Laboratory waste containers are used to collect waste liquids generated in laboratories. These waste liquids may include chemical waste liquids, waste liquids from biological experiments, organic solvent waste liquids, etc. Waste liquid containers are usually designed to be airtight to prevent leakage. In addition, some waste liquid containers may also have corrosion-resistant properties to accommodate different types of waste liquids.

[0003] Existing laboratory waste liquid containers have a simple structure, consisting of only a container body and a lid. They suffer from poor sealing, and when waste liquid is stored in the container, a large amount of volatile toxic and harmful gases are released, resulting in serious odor problems. This not only pollutes the laboratory environment but also endangers the health of laboratory personnel, posing a safety hazard. Therefore, a new type of laboratory waste liquid storage container is proposed. Summary of the Invention
