1. A liquid containment bottle comprising:
a bottle body defining an internal space configured to contain liquid; and
a cap configured to be attached to the bottle body,
wherein the bottle body has:
a base end surface;
a nozzle projecting from the base end surface in a first direction; and
a circular wall which is positioned in a surrounding of the nozzle with a spacing distance with respect to the nozzle in a second direction crossing the first direction, and which projects from the base end surface in the first direction,
the nozzle has:
a forward end surface formed with an opening through which the liquid contained in the internal space flows out;
a seat surface located at a position which is closer to the circular wall than the forward end surface in the second direction, and which is closer to the internal space than the forward end surface in the first direction; and
a groove which is formed in the seat surface and which has an end part connected to a space between the nozzle and the circular wall, and
the cap has:
a sealing part configured to seal the opening in an attached state in which the cap is attached to the bottle body; and
a projecting piece which projects from a surrounding of the sealing part and which is configured to make contact with the seat surface in the attached state.
