Printing material applying apparatus

1. A printing material applying apparatus comprising:

a container configured to store a printing material to be supplied to an applying unit configured to apply the printing material used to perform printing on a print medium;

a cap portion configured to be detachably attached to an inlet portion, which is provided in the container and through which the printing material is loaded into the container, and capable of closing the inlet portion;

a first cover portion including a first engaging portion and a contact piece, and configured to be capable of moving between a closing position where the cap portion is covered and an opening position where the cap portion is exposed;

a second engaging portion configured to engage with the first engaging portion so as to regulate movement of the first cover portion from the closing position to the opening position; and

a biasing unit which is separated from the cap portion and is configured to bias the first cover portion in an opening direction by contact with the contact piece of the first cover portion.

2. The apparatus according to claim 1 , wherein the first cover portion is swingably supported between the closing position and the opening position.

3. The apparatus according to claim 2 , further comprising a cap member including the cap portion and configured to be swingably supported between a closing position where the cap portion closes the inlet portion and an opening position where the cap portion opens the inlet portion,

wherein at the closing position of the first cover portion, the first cover portion covers the cap member located at the closing position, and

the first cover portion includes a pressing portion configured to press the cap member to the closing position along with swing of the first cover portion to the closing position.

4. The apparatus according to claim 2 , wherein

the first cover portion includes a base-side end portion serving as a swing center of the first cover portion and a distal-side end portion on the opposite side of the base-side end portion, and

the contact piece of the first cover portion is located at a position closer to the base-side end portion than the distal-side end portion.

5. The apparatus according to claim 2 , further comprising a second cover portion configured to be swingably supported between a closing position where the first cover portion is covered and an opening position where the first cover portion is openably/closably exposed,

wherein the first engaging portion contacts the second engaging portion in the opening direction of the first cover portion so as to engage with the second engaging portion, and

the first cover portion located at the closing position is pressed by the second cover portion located at the closing position such that the first engaging portion is separated from the second engaging portion in a closing direction of the first cover portion.

6. The apparatus according to claim 5 , wherein the second cover portion includes a contact portion configured to press the first cover portion in the closing direction by contacting the first cover portion.

7. The apparatus according to claim 1 , wherein

the printing material is ink, and

the printing material applying apparatus is a printing apparatus configured to perform printing by discharging the ink to the print medium by the applying unit.

8. The apparatus according to claim 5 , comprising a first container as the container and a second container as the container, wherein

the first cover portion is provided on each of the first container and the second container, and

one second cover portion is provided commonly to the first container and the second container.

9. The apparatus according to claim 5 , further comprising an apparatus main body,

wherein the second cover portion is configured to form a top part of the printing material applying apparatus and be swingably supported by the apparatus main body.

10. The apparatus according to claim 1 , wherein the contact piece is a plate-shaped member projecting to a side of the first cover portion.

11. The apparatus according to claim 1 , further comprising a cap member including the cap portion and configured to be swingably supported between a closing position where the cap portion closes the inlet portion and an opening position where the cap portion opens the inlet portion,

wherein the biasing unit is separated from the cap member.

12. A printing material applying apparatus comprising:

a container configured to store a printing material to be supplied to an applying unit configured to apply the printing material;

a cap member including a cap portion capable of closing an inlet portion, which is provided in the container and through which the printing material is loaded into the container, and a first engaging portion, the cap member being capable of moving between a closing position where the cap portion closes the inlet portion and an opening position where the cap portion opens the inlet portion;

a second engaging portion configured to engage with the first engaging portion so as to regulate movement of the cap member from the closing position to the opening position; and

a biasing unit which is separated from the cap member and is configured to bias the cap member in an opening direction by contact with the cap member in a state.

13. The apparatus according to claim 12 , wherein

the printing material is ink, and

the printing material applying apparatus is a printing apparatus configured to perform printing by discharging the ink to a print medium by the applying unit.
