Abstract
A cap includes a cap body and a check valve. The cap body is attached to a spout of an ink container supplying an ink to one direction. The check valve has a check valve ball inside and prevents backward flow of the ink to the other direction. The cap body includes a first thread portion, a supplying port and a second thread portion. The first thread portion is screwed with an outer circumference face of the spout to seal the spout. The supplying port is provided inside the first thread portion and has an inner diameter smaller than the spout. The second thread portion is provided around the supplying port inside the spout. The check valve is screwed with the second thread portion.
