Patent attributes
A liquid container includes a container body including an inner space accommodating a liquid formed therein, a liquid port formed at a top thereof to allow the liquid to flow into/out of the inner space, and a holding protrusion which protrudes toward an inside and is formed on an inner circumferential surface thereof, a cap inserted into the liquid port and then coupled with the container body, and a stopper coupled with the cap, disposed to be spaced apart from a bottom surface of the cap, configured to protrude in an outward-radial direction and to be held by the holding protrusion to limit a movement distance of the cap when the cap moves upward, and formed of an elastic material to allow the cap to be separable from the container body by a certain external force applied to the cap.
