Liquid container

A liquid container comprising:

• a container body including an outlet having a cylindrical shape, a male screw being formed on an outer circumferential surface of the outlet;
• and
• a screw cap having a cylindrical shape, a female screw being formed on an inner circumferential surface of the screw cap, the screw cap being configured to be screwed into the outlet in a state that the outer circumferential surface of the outlet and the inner circumferential surface of the screw cap face each other, wherein:
• the outlet includes a projection disposed, on the outer circumferential surface of the outlet, at a position adjacent to a base of the cylindrical shape of the outlet;
• and
• the screw cap includes:
• a first convex part which is disposed on the inner circumferential surface of the screw cap and which has an inclined part and an interfering part, the inclined part being configured to allow the projection to pass through the first convex part in a case where the screw cap is rotated in a first direction of a rotation direction to be screwed into the outlet, the interfering part being configured to interfere with the projection to prevent the screw cap from rotating in a second direction, opposite to the first direction, of the rotation direction;
• and
• a second convex part configured to allow the projection to pass through the second convex part, and to come into contact with the projection so as to cause a friction force in the rotation direction, in a case where the screw cap is screwed into the outlet.
