Abstract:
A liquid container for accommodating a recording liquid supplied to a liquid ejection recording head, said liquid container being detachably connectable to a supply tube which is in fluid communication with the liquid ejection recording head, said liquid container comprising:a liquid accommodating portion for accommodating the recording liquid to be supplied to the liquid ejection recording head; a supply port into which the supply tube is insertable, said supply port for permitting supply of the liquid to the recording head from the liquid accommodating portion, said supply port being provided in said liquid accommodating portion; a capillary force generating member for generating a capillary force to absorb recording liquid deposited on a surface of the supply tube and in said supply port, the absorbed recording liquid being absorbed into a space other than said liquid accommodating portion in said liquid container; wherein a capillary force A generated in an absorption region for absorbing the recording liquid remaining in said supply port adjacent said supply port and a capillary force B in a storing region for storing the recording liquid absorbed in the absorption region, satisfy Awherein said capillary force generating member constitutes a groove at least at a portion corresponding to said absorption region.
