CHEMICAL CONTAINER
Document Type and Number:
WIPO Patent Application WO/2020/040415
Kind Code:
A1
Abstract:
The present invention is for providing a chemical container in which an excessive increase in internal pressure due to gas generation can be prevented by stably securing a discharge path for gas generated from chemicals and discharging the gas even when the posture or inclination of the container changes in various ways due to, for instance, the container overturning or falling over. A chemical container according to the present invention comprises: a container body having a storage chamber in which chemicals are stored; an exhaust port disposed on one side of the container body and connecting the storage chamber and the outside of the container body to enable fluid flow therebetween; an exhaust tube disposed in the storage chamber so as to be connected to the exhaust port to enable fluid flow therebetween; and an exhaust buoyant body. The exhaust buoyant body is provided with: a buoyant body which is disposed in the storage chamber and connected to the exhaust tube so as to be able to float on the chemicals stored in the storage chamber; an exhaust path provided on the inside of the buoyant body and connecting the storage chamber and the exhaust tube to enable fluid flow therebetween; and a filter membrane coupled to the buoyant body so as to allow gas to pass through the exhaust path while preventing the chemicals from passing therethrough.
