<P>PROBLEM TO BE SOLVED: To provide a liquid vessel capable of preventing the liquid from sagging and dropping without being influenced by the posture of the vessel. <P>SOLUTION: The liquid vessel is equipped with a vessel main body 2 and a nozzle lid part 5. A partitioning material 16 is provided between the cylindrical part 10 of the nozzle lid part 5 and the inside of the vessel main body 2, and a cell 22 is formed between a communicating path 14 and a liquid storing room 6 by the partitioning material 16. A bellows-like expansion and contraction part 18 is provided on the partitioning material 16, and a pressing valve 19 is provided on the tip part (lower part) of the expansion and contraction part 18. When the vessel main body 2 is compressed to load an inner pressure in the vessel, the expansion and contraction part 18 is contracted and the pressing valve 19 is opened. When the inner pressure is released, the expansion and contraction part 18 is returned to the original position. <P>COPYRIGHT: (C)2008,JPO&INPIT |
