Abstract
An ejection material is injected into a container through a pipe. Thereafter, the pipe is blocked at a blocked part and then the pipe is cut off. The pipe is cut off such that the blocked part is included in a portion of the pipe connected to the container.
Claims17
An ejection-material injecting method of injecting an ejection material into a container in an ejection apparatus capable of ejecting the ejection material in the container from an ejection head, comprising:
- a connecting step of connecting the container and a tank configured to contain the ejection material to each other by using a pipe;
- an injecting step of injecting the ejection material in the tank into the container through the pipe;
- a blocking step of blocking the pipe in a state of being connected between the tank and the container after the injecting step;
- and
- a cutting step of cutting off the pipe after the blocking step such that the pipe is separated into a first portion connected to the container and a second portion connected to the tank, and that a blocked part of the pipe blocked in the blocking step is included in the first portion.

An ejection-material ejection apparatus comprising:
- a container configured to contain an ejection material;
- an ejection head capable of ejecting the ejection material in the container;
- a first pipe connected to the container so as to inject the ejection material into the container;
- a second pipe connected to the container so as to discharge the ejection material from the container;
- and
- a covering configured to cover the first pipe,

4 more elements
An ejection-material ejection apparatus comprising:
- a container configured to contain an ejection material;
- an ejection head capable of ejecting the ejection material in the container;
- a pipe connected to the container so as to inject the ejection material into the container;
- and
- a covering configured to cover the pipe,
- wherein the pipe includes a blocked part blocked after injection of the ejection material into the container, and a cut-off part cut off in such a way as to retain the blocked part,
- wherein the container includes a passage provided separately from the pipe and connected to the container, and
- wherein the passage includes:
- a first opening being open to the container so as to supply the ejection material contained in the container into the passage;
- and
- a second opening being open to the container so as to discharge the ejection material, which is supplied from the first opening into the passage, to the container, and
- wherein a pump and a filter configured to filtrate the ejection material are provided in the passage between the first opening and the second opening.
