Abstract
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.
Claims2
A liquid container comprising:
- a container body comprising an inner space and a liquid port being formed on top of the inner space,
- wherein a holding protrusion which protrudes inward formed between the inner space and the liquid port so that the inner space and the liquid port are distinguished each other by the holding protrusion,
- wherein a coupling screw is formed on an inner circumferential surface of the container body,
- wherein the liquid port has an upper diameter that is greater than a lower diameter,
- and
- wherein a stopper accommodation groove is formed on a bottom surface of the holding protrusion;
- a cap comprising an insertion portion inserted into the liquid port and with an extraction flow path formed on an outer circumferential surface of the insertion portion, the extraction flow path being recessed in a vertical direction, a handle portion located above the insertion portion and exposed outward from the container body, and a first sealing portion formed of an elastic material at a bottom end of the insertion portion and compressed by the holding protrusion to seal the inner space when the cap is completely closed;
- and
- a stopper is uniformly formed with the first sealing portion and protrudes in an outward radial direction, wherein the stopper is configured to be accommodated in the stopper accommodation groove when the cap moves upward so that a horizontal movement of the stopper is prevented, and formed of an elastic material to allow the cap to be removable from the container body,
- wherein an upper portion of the stopper is upwardly projected and directly accommodated in the stopper accommodation groove.
