Container lid

Abstract

The container lid comprises a side wall portion having a fitting portion that fits onto the side wall portion of the container, and a top portion that closes the opening of the container. A first notch (a roughly D-shaped line shown in black in the reference perspective view) is formed on the top portion, forming a first on-off valve. A second notch (a roughly C-shaped line shown in black in the reference perspective view) is also formed, forming a second on-off valve. When the upper lip presses against the roughly D-shaped protrusion on the first on-off valve, the tip side of the first on-off valve (right end side in the plan view) is pushed inward into the container, opening the first on-off valve, and the tip side of the second on-off valve (left end side in the plan view) is lifted outward into the container, opening the second on-off valve.
