Abstract

A waste liquid container includes an accommodation chamber including an opening that is open upward of the waste liquid container in a mounted state where the waste liquid container is mounted in the mounting portion, the accommodation chamber being configured to accommodate the liquid, and a contact portion provided at a surface that intersect with a bottom surface and an upper surface of the waste liquid container, the contact portion being configured to contact a horizontal plane and set a posture of the accommodation chamber with respect to the horizontal plane in a placement state where the waste liquid container is placed at the horizontal plane with the surface facing downward, wherein in the placement state, an inner surface is in an inclined state where the bottom surface is lower than the upper surface, the inner surface serving as a lower surface of the accommodation chamber.

First claim

What is claimed is:

1. A waste liquid container including a bottom surface, an upper surface, and a plurality of side surfaces that intersect with the bottom surface and the upper surface, the waste liquid container detachably mounted in a mounting portion including a discharge portion configured to discharge liquid with the bottom surface facing downward, the waste liquid container comprising:
an accommodation chamber including an opening that is open upward of the waste liquid container in a mounted state where the waste liquid container is mounted in the mounting portion, the accommodation chamber being configured to accommodate the liquid; and
a contact portion provided at a first surface of the plurality of side surfaces, of the waste liquid container in the mounted state, wherein
in a placement state where the waste liquid container is placed at a horizontal plane with the first surface facing downward, the contact portion is configured to contact a horizontal plane and set a posture of the accommodation chamber with respect to the horizontal plane, and
in the placement state, an inner surface serving as a lower surface of the accommodation chamber is in an inclined state where the bottom surface of the waste liquid container is lower than the upper surface of the waste liquid container.

2. The waste liquid container according to claim 1 , wherein
the contact portion includes at least one protrusion provided at the first surface.

3. The waste liquid container according to claim 2 , wherein
the at least one protrusion is provided at a plurality of locations sandwiching a center in a lateral direction of the first surface in the mounted state.

4. The waste liquid container according to claim 2 , wherein
the at least one protrusion extends across a center in a lateral direction of the first surface in the mounted state.

5. The waste liquid container according to claim 2 , wherein
the at least one protrusion is located closer to the upper surface than to the bottom surface.

6. The waste liquid container according to claim 2 , comprising a cover configured to constitute the upper surface of the waste liquid container, and cover the opening of the accommodation chamber, wherein
the at least one protrusion is integrally formed with the cover.

7. The waste liquid container according to claim 6 , wherein
the at least one protrusion is formed at the first surface by a portion of the cover extending through the first surface.

8. The waste liquid container according to claim 1 , wherein
a waste liquid introduction portion, into which the liquid discharged from the discharge portion is introduced, is provided at the first surface serving as a front surface in a mounting direction when the waste liquid container is mounted in the mounting portion.

9. The waste liquid container according to claim 8 , wherein
the waste liquid introduction portion is separated from the horizontal plane in the placement state.

10. The waste liquid container according to claim 8 , further comprising a circuit board including a coupling terminal configured to be electrically coupled to a mounting portion side coupling terminal provided at the mounting portion, wherein
in the placement state, the first surface is in the inclined state where the bottom surface is lower than the upper surface, and
the circuit board is located on the side of the upper surface with respect to the waste liquid introduction portion.
