As shown in fig. 2, 8 to 12, when the ink bottle 100 of the present embodiment is used to replenish ink to a printer provided with the second filling port 220, the ink bottle 100 is inverted, and a part of the tubular portion 142 of the ink bottle 100 is inserted into the second filling port 220, and then the body member 110 of the ink bottle 100 is pressed, the pressure of the ink against the valve member 130 causes the self-closing slit to open, and the ink is pressed into the ink tank 200.

As a first modification of the second embodiment, the inner diameter D1 of the tubular portion 142 of the tube portion 140 may be set smaller than the outer diameter of the ink supply needle 211, and preferably the inner diameter D1 of the tubular portion 142 is slightly smaller than the outer diameter of the ink supply needle 211.

When the ink bottle 100 according to this modification is used to replenish ink into the ink tank 200 of the printer provided with the first filling port 210, the ink bottle 100 is inverted, and then the ink bottle 100 is moved in the direction of the first filling port 210, the inner wall of the tubular portion 142 is brought into contact with the ink supply needle 211, and is deformed by the ink supply needle 211, and the ink supply needle 211 can still be inserted into the tubular portion 142 and communicate with the ink flow path through the valve member 130.

The inner diameter D1 of the tubular portion 142 of the tube portion 140 of the modification is smaller than the outer diameter of the ink supply needle 211, and the ink supply needle 211 can be inserted only by slightly deforming the tube portion 140 during filling, so that the tube portion can be used for a filling port structure provided with the ink supply needle 211, and the tube portion is high in universality and convenient to use.

As a second modification of the second embodiment, the outer diameter D2 of the tubular portion 142 of the tube portion 140 may be set to be larger than the inner diameter of the second filling port 220, and preferably the outer diameter D2 of the tubular portion 142 is slightly larger than the inner diameter of the second filling port 220.

When the ink bottle 100 according to this modification is used to replenish ink to a printer provided with the second filling port 220, the ink bottle 100 is inverted, the tubular portion 142 of the tubular portion 140 is brought into contact with the second filling port 220 and is inserted into the second filling port 220 after being deformed by pressing, then the body member 110 of the ink bottle 100 is pressed, the self-closing slit is opened by the pressure of the ink to the valve member 130, and the ink is pressed into the ink tank 200.

The outer diameter D2 of the tubular portion 142 of the tube portion 140 of the present modification is larger than the inner diameter of the second filling port 220, and the tube portion 140 can be inserted into the second filling port 220 by being slightly deformed by pressing during filling, so that the tube portion can be used for a filling port structure provided with no ink supply needle 211, and the tube portion is highly versatile and convenient to use.

In the second embodiment and the modification thereof, the inner and outer diameter dimensions of the tubular portion 142 may be combined, for example, the inner diameter of the tubular portion 142 is smaller than the outer diameter of the ink supply needle 211, and the outer diameter of the tubular portion 142 is larger than the inner diameter of the second filling port 220 (combination of the first modification and the second modification); for another example, the inner diameter of the tubular portion 142 is smaller than the outer diameter of the ink supply needle 211, and the outer diameter of the tubular portion 142 is smaller than the inner diameter of the second filling port 220 (combination of the second embodiment and the first modification); further, if the inner diameter of the tubular portion 142 is larger than the outer diameter of the ink supply needle 211, and if the outer diameter of the tubular portion 142 is larger than the inner diameter (combination of the second embodiment and the second modification) … … of the second filling port 220, the design of the inner and outer diameter dimensions of the tubular portion 142 becomes more free based on the deformable characteristics of the barrel portion 140, and various combinations of the inner and outer diameter dimensions can realize that the ink bottle 100 is commonly used for different filling port structures, and the ink bottle has a simple structure and strong versatility.

What has been described above is merely some embodiments of the present utility model. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the utility model.
