  • Patent number: 11235580
    Abstract: There is provided a tank including a liquid inlet port, an atmosphere open port, a liquid outflow port, a first liquid chamber having a first atmosphere communication channel, a second liquid chamber being in communication with the first liquid chamber and having a second atmosphere communication channel, and a liquid channel. The liquid inside the liquid channel is movable along with a liquid consumption of a liquid consuming device connected to the tank. With the tank in a usage posture, when the liquid is stored in the first liquid chamber and the second liquid chamber, the liquid level of the liquid stored in the first liquid chamber is formed independently from the liquid level of the liquid stored in the second liquid chamber.

  • Patent number: 10752005
    Abstract: When printing is performed by ejecting an ink from heads of a printer, a CPU drives a pump and performs main tank-side circulation processing that circulates the ink in a main tank, a tank-side supply flow path, a first bypass flow path and a tank-side circulation flow path. Therefore, a printer can perform the main tank-side circulation processing without waiting for the end of the printing, and it is possible to quickly replenish the sub tank with the ink that decreases during the printing.

  • Patent number: 10131151
    Abstract: An ink container for an inkjet printer includes an ink containing portion. The ink containing portion contains ink and includes an upper surface including a placing portion, a refill port disposed on the upper surface, and a sealing member. The sealing member includes a sealing portion located at the center and an outer peripheral portion located at the outer periphery. An outer diameter of the sealing portion matches with an inner diameter of the refill port. The placing portion further includes a first recess portion and a positioning portion extending in a circumferential direction of the first recess portion. The first recess portion is configured to receive the sealing member and not to contact the sealing portion. The positioning portion includes a restricting portion configured to reduce horizontal movement of the outer peripheral portion and a supporting portion configured to vertically support the outer peripheral portion.
