摘要：
A liquid container including a first chamber for containing a reservoir of liquid, a second chamber containing a negative pressure producing material, an air vent for fluid communication with ambient air, a liquid supply port for supplying liquid out of the second chamber, a communication path for fluid communication between the first and second chambers where the first chamber is generally sealed by the ambient air except through the communication path, and a wall extending from the communication port. The communication path has a first region for permitting movement of air from the second chamber to the first chamber and a second region for permitting movement of the liquid from the first chamber to the second chamber.
