Liquid containment bottle and liquid supply apparatus
A liquid containment bottle includes: a bottle body defining an internal space configured to contain liquid; and a cap configured to be attached to the bottle body. The bottle body has: a base end surface, a nozzle projecting from the base end surface in a first direction, and a circular wall positioned in a surrounding of the nozzle and projecting from the base end surface in the first direction. The nozzle has: a forward end surface formed with an opening through which the liquid 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, and which is closer to the internal space than the forward end surface in the first direction, and a groove formed in the seat surface and having an end part connected to a space between the nozzle and the circular wall.
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.
2. The liquid containment bottle according to claim 1 , wherein
the nozzle has a nozzle upper part which is positioned above the seat surface and which has a cylindrical shape,
the seat surface has a ring shape and is oriented upward, and
the projecting piece has a cylindrical shape.
3. The liquid containment bottle according to claim 1 , wherein the groove has a bottom surface which is inclined downward toward the internal space.
4. The liquid containment bottle according to claim 1 , wherein
the circular wall has a cylindrical shape, and
the circular wall includes a curved plate and a connecting plate which are connected to each other and each of which forms a part in a circumferential direction of the cylindrical shape.
5. The liquid containment bottle according to claim 4 , wherein the seat surface has a first area between the nozzle and a part in which the seat surface and the connecting plate cross each other, and
the groove is formed in a second area, in the seat surface, which is different from the first area.
6. The liquid containment bottle according to claim 4 , wherein
the liquid containment bottle is used to supply the liquid to a tank of a liquid consuming apparatus, and
the liquid containment bottle further comprises a key member which is formed in the circular wall and which is configured to conform to a receiver key member provided on a surrounding of a supply port of the tank.
7. The liquid containment bottle according to claim 1 , wherein the cap is configured to be screwed with respect to the circular wall and to be attached to the bottle body.
8. The liquid containment bottle according to claim 1 , wherein an upper end of the circular wall is positioned above the forward end surface.
9. The liquid containment bottle according to claim 1 , further comprising:
a first bottom part positioned below the seat surface and configured to partition the space between the nozzle and the circular wall; and
a second bottom part positioned below the first bottom part and configured to partition the space between the nozzle and the circular wall,
wherein the end part of the groove is located above the second bottom part.
10. The liquid containment bottle according to claim 1 , further comprising a partition configured to divide the space between the nozzle and the circular wall into a plurality of small spaces.
11. A liquid supply apparatus comprising:
the liquid containment bottle as defined in claim 1 ; and
a tank having a containment chamber configured to contain the liquid,
wherein the tank has:
a recessed part; and
a communicating tube which is positioned in the recessed part and which has a first channel and a second channel, the communicating tube communicating the containment chamber with outside, and
the circular wall of the bottle body is configured to be inserted into the recessed part of the tank and the communicating tube of the tank is configured to be inserted into the opening of the nozzle of the bottle body, to thereby connect the bottle body to the tank and to allow the liquid to flow out from the internal space of the bottle body to the containment chamber of the tank.
