Abstract:
A liquid container for a liquid jet recording apparatus, comprising:a first chamber containing negative pressure producing material and having a liquid outlet connectable to a liquid jet head to supply liquid from the liquid container to the liquid jet head and an air vent for allowing ambient air into the liquid container;a second chamber communicating with the first chamber by means of a communication path, except for which said second chamber is substantially hermetically sealed; andan ambient air introducing path for introducing the ambient air into said second chamber by permitting air-liquid exchange at said communication path when the liquid is supplied out through said liquid outlet while a liquid level in said first chamber is above said communication path, said air vent and said ambient air introducing path being separated from each other by said negative pressure producing material, and said ambient air introducing path being provided as a gap formed by said negative pressure producing material with the gap being dimensioned such that it is apart from an inside surface of said first chamber.
