Abstract

The ink adhesion surface sides of the plug member removed from the ink jet recording apparatus and the cap removed from the ink replenishment container are faced each other, superposed and attached so that the ink adhesion surfaces are not exposed to the outside.

First claim

What is claimed is:

1. A liquid replenishment container comprising:
a container body containing a liquid with which a liquid reservoir container is replenished, the liquid reservoir container being provided with a liquid reservoir portion, a circular-shaped liquid inlet port and a plug member, wherein
the liquid reservoir portion is constructed to be provided to a liquid ejection recording apparatus and to reserve the liquid to be supplied to a recording head that ejects the liquid,
the liquid inlet port is configured to enable the liquid reservoir portion to be replenished with the liquid from the outside, and
the plug member is provided with a seal portion, a flange portion and a knob portion, the seal portion having an outer diameter of which value is same as that of an inner diameter of an opening of the liquid inlet port, the flange portion having a diameter larger than the inner diameter of the opening, the knob portion extending from the flange portion;

the liquid replenishment container further comprising:
a liquid replenishing port constructed for insertion into the liquid inlet port to replenish the liquid reservoir container with the liquid through the liquid inlet port from the container body; and
a cap with a cylindrical shape of which one end is closed and the other end is open, the cap being configured to be detached from the liquid replenishing port at the time of replenishing and to be attached to the liquid replenishing port at the time of storing the liquid;
wherein
the cap is provided with a sealing portion, an outer peripheral surface, and a cylindrical-shaped first rib inside thereof, the sealing portion sealing the replenishing port, the outer peripheral surface covering the surroundings of the replenishing port while abutting on the container body, and the first rib having an inner peripheral surface abutting on the surroundings at the vicinity of the tip of the replenishing port, and
the cap is configured so that when the plug member is housed in the cap with the seal portion side of the plug member facing an opening side of the cap, an outer periphery of the first rib attaches to an inner periphery of the seal portion of the plug member.

2. The liquid replenishment container according to claim 1 , wherein the cap is provided with a cylindrical-shaped second rib having a diameter larger than the diameter of the first rib and being longer than the first rib, and an end portion of an opening side of the second rib is configured to abut on the flange portion.

3. The liquid replenishment container according to claim 1 , wherein
a first screw portion is provided on an inner peripheral surface of the seal portion, the first screw portion being configured to screwing to the liquid inlet port,
a second screw portion is provided on an outer peripheral surface of the first rib, the second screw portion being configured to screwing to the first screw portion, and
the plug member and the cap are configured to be superposed by screwing the first screw portion and the second screw portion each other.

4. A liquid replenishment container according to claim 1 , wherein the cap is disconnectably connected to the container body.

5. A liquid replenishment container according to claim 1 , wherein the cap is completely removable from the container body.

6. A liquid replenishment system comprising:
a liquid reservoir container provided with a liquid reservoir portion, a circular-shaped liquid inlet port and a plug member, wherein
the liquid reservoir portion is constructed to be provided to a liquid ejection recording apparatus and to reserve the liquid to be supplied to a recording head that ejects the liquid,
the liquid inlet port is configured to enable the liquid reservoir portion to be replenished with the liquid from the outside, and
the plug member is provided with a seal portion, the seal portion having an outer diameter of which value is same as that of an inner diameter of an opening of the liquid inlet port;

the liquid replenishment system further comprising:
a liquid replenishment container provided with a container body, a liquid replenishing port and a cap with a cylindrical shape of which one end is closed and the other end is open;
wherein
the container body is constructed to contain the liquid with which the liquid reservoir container is replenished,
the liquid replenishing port is constructed for insertion into the liquid inlet port to replenish the liquid reservoir container with the liquid through the liquid inlet port from the container body,
the cap is configured to be detached from the liquid replenishing port at the time of replenishing and to be attached to the liquid replenishing port at the time of storing the liquid;
the cap is provided with a sealing portion, an outer peripheral surface, and a cylindrical-shaped first rib inside thereof, the sealing portion sealing the liquid replenishing port, the outer peripheral surface covering the surroundings of the liquid replenishing port while abutting on the container body, and the first rib having an inner peripheral surface abutting on the surroundings at the vicinity of the tip of the liquid replenishing port, and
the cap is configured so that when the plug member is housed in the cap with the seal portion side of the plug member facing an opening side of the cap, an outer periphery of the first rib attaches to an inner periphery of the seal portion of the plug member.

7. The liquid replenishment system according to claim 6 , wherein
the plug member is provided with a flange portion and a knob portion, the flange portion having a diameter larger than the inner diameter of the opening, the knob portion extending from the flange portion, and
the cap is provided with a cylindrical-shaped second rib having a diameter larger than the diameter of the first rib and being longer than the first rib, and an end portion of an opening side of the second rib is configured to abut on the flange portion.

8. The liquid replenishment system according to claim 6 , wherein
a first screw portion is provided on an inner peripheral surface of the seal portion, the first screw portion being configured to screwing to the liquid inlet port,
a second screw portion is provided on an outer peripheral surface of the first rib, the second screw portion being configured to screwing to the first screw portion, and
the plug member and the cap are configured to be superposed by screwing the first screw portion and the second screw portion each other.
