Abstract

A container for liquid replenishment for replenishing liquid in a liquid ejection apparatus comprises a container body capable of containing the liquid, a spout fitted to the container body and having a front end section including a front end surface and a liquid outlet for allowing the liquid to flow out therefrom, a lid member removably attached to the spout to cover the spout and a liquid absorber arranged on the spout. The liquid outlet is open in the front end surface of the spout and the liquid absorber is arranged at least on an area of the front end surface not occupied by the liquid outlet.

First claim

What is claimed is:

1. A container for liquid replenishment for replenishing liquid in a liquid ejection apparatus, the container comprising:
a container body capable of containing the liquid;
a spout fitted to the container body and having a front end section including a front end surface and a liquid outlet for allowing the liquid to flow out therefrom;
a lid member attached to the spout to cover the spout in such a manner that the lid member can be removed for liquid replenishment; and
a liquid absorber fixed on the spout, the liquid absorber having a front surface on a side opposite to a surface fixed on the spout such that the front surface is exposed when the lid member is removed;
the liquid outlet being open in the front end surface of the spout;
the liquid absorber being arranged at least on an area of the front end surface not occupied by the liquid outlet.

2. The container according to claim 1 ,
wherein the lid member has a tubular section configured to receive the front end section of the spout such that, as the lid member is attached to the spout, the front end section extends into the inside of the tubular section.

3. A container for liquid replenishment for replenishing liquid in a liquid ejection apparatus, the container comprising:
a container body capable of containing the liquid;
a spout fitted to the container body and having a front end section including a front end surface and a liquid outlet for allowing the liquid to flow out therefrom;
a lid member removably attached to the spout to cover the spout; and
a liquid absorber arranged on the spout;
the liquid outlet being open in the front end surface of the spout;
the liquid absorber being arranged at least on an area of the front end surface not occupied by the liquid outlet,
wherein the lid member has a tubular section configured to receive the front end section of the spout such that, as the lid member is attached to the spout, the front end section extends into the inside of the tubular section, and
wherein an auxiliary absorber is arranged around the tubular section of the lid member such that, as the lid member is attached to the spout, the auxiliary absorber surrounds the spout.

4. A container for liquid replenishment for replenishing liquid in a liquid ejection apparatus, the container comprising:
a container body capable of containing the liquid;
a spout fitted to the container body and having a front end section including a front end surface and a liquid outlet for allowing the liquid to flow out therefrom;
a lid member removably attached to the spout to cover the spout; and
a liquid absorber arranged on the spout;
the liquid outlet being open in the front end surface of the spout;
the liquid absorber being arranged at least on an area of the front end surface not occupied by the liquid outlet,
wherein the lid member has a tubular section configured to receive the front end section of the spout such that, as the lid member is attached to the spout, the front end section extends into the inside of the tubular section, and
wherein the front end surface has a profile comprising a central side and an outer peripheral side such that the central side protrudes more than the outer peripheral side.

5. A container for liquid replenishment for replenishing liquid in a liquid ejection apparatus, the container comprising:
a container body capable of containing the liquid;
a spout fitted to the container body and having a front end section including a front end surface and a liquid outlet for allowing the liquid to flow out therefrom;
a lid member removably attached to the spout to cover the spout; and
a liquid absorber arranged on the spout;
the liquid outlet being open in the front end surface of the spout;
the liquid absorber being arranged at least on an area of the front end surface not occupied by the liquid outlet,
wherein the lid member has a tubular section configured to receive the front end section of the spout such that, as the lid member is attached to the spout, the front end section extends into the inside of the tubular section, and
wherein the front end surface has a profile comprising a central side and an outer peripheral side such that the outer peripheral side protrudes more than the central side.

6. The container according to claim 5 , wherein
the liquid absorber is arranged along an outer periphery of the front end surface.

7. A container for liquid replenishment for replenishing liquid in a liquid ejection apparatus, the container comprising:
a container body capable of containing the liquid;
a spout fitted to the container body and having a front end section including a front end surface and a liquid outlet for allowing the liquid to flow out therefrom;
a lid member removably attached to the spout to cover the spout; and
a liquid absorber arranged on the spout;
the liquid outlet being open in the front end surface of the spout;
the liquid absorber being arranged at least on an area of the front end surface not occupied by the liquid outlet,
wherein the lid member has a tubular section configured to receive the front end section of the spout such that, as the lid member is attached to the spout, the front end section extends into the inside of the tubular section, and
wherein the liquid absorber is also arranged on a lateral surface of the spout.

8. The container according to claim 7 , wherein
the liquid absorber on the front end surface and the liquid absorber on the lateral surface of the spout are unified to form an integral liquid absorber.

9. A liquid replenishment structure comprising:
a container for liquid replenishment for replenishing liquid in a liquid ejection apparatus, the container having a container body capable of containing the liquid, a spout fitted to the container body and having a front end section including a front end surface and a liquid outlet for allowing the liquid to flow out therefrom, a lid member removably attached to the spout to cover the spout and a liquid absorber arranged on the spout, the liquid outlet being open in the front end surface of the spout, the liquid absorber being arranged at least on an area of the front end surface not occupied by the liquid outlet;
a recess arranged in the liquid ejection apparatus and adapted for receiving the spout of the container for liquid replenishment;
an inlet flow path member arranged in the recess and configured to be inserted into the liquid outlet of the container for liquid replenishment; and
a droplet collection port arranged at a bottom surface of the recess so as to collect liquid droplets squeezed out from the liquid absorber upon being pinched and compressed between the spout and the recess in response to an operation of fitting the container for liquid replenishment to the liquid ejection apparatus.

10. A liquid replenishment structure comprising:
a container for liquid replenishment for replenishing liquid in a liquid ejection apparatus, the container having a container body capable of containing the liquid, a spout fitted to the container body and having a front end section including a front end surface and a liquid outlet for allowing the liquid to flow out therefrom, a lid member removably attached to the spout to cover the spout and a liquid absorber arranged on the spout, the liquid outlet being open in the front end surface of the spout, the liquid absorber being arranged at least on an area of the front end surface not occupied by the liquid outlet;
a recess arranged in the liquid ejection apparatus and adapted for receiving the spout of the container for liquid replenishment;
an inlet flow path member arranged in the recess and configured to be inserted into the li
