A functional container with a non-return check valve is provided to discharge moisture or gas produced inside the container, such as a cup, a glass, etc., quickly in real time mode. A container(20) comprises a check valve(80) having a through-hole(140) formed at a bottom portion(40) of the container to discharge fluid and air in one direction. Also, a detachable liquid filter discharge unit(180) is provided at the lower portion of the container to store liquid discharged from the check valve. The check valve further includes a disk(100) to open/close the through-hole, and a leaf or circular spring(120) to block or open a gas and liquid passage. With the spring, expanded air inside the container is easily discharged, while the outside air is blocked. |
