摘要 <P>PROBLEM TO BE SOLVED: To provide a pouch vessel which enables the operation of refilling of contents to be surely performed with ease. <P>SOLUTION: A spout with a mouth part 22 capable of being opened/closed by a screw cap 23 is attached to a vessel body which is formed like a bag by using a flexible sheet. In the mouth part 22, a circular flange 223, which overhangs outward from an outer peripheral surface thereof, is continuously provided at the lower end of a thickly formed lower half part 222, and a protrusive streak 225, which is protruded outward in a radial direction, is formed on the outer peripheral surface of the half part 222. A groove 226, which is elongated from an upper end of the half part 222 to an outer edge of the flange 223, is partially formed in the outer peripheral surface of the half part 222, including the protrusive streak 225, and the top surface of the flange 223. When the mouth part 22 of the pouch vessel is fitted into a mouth part M of a bottle vessel, an air outflow passage, which allows the outflow of air in the bottom vessel B, is formed between the mouth part M of the bottle vessel and the mouth part 22 of the pouch vessel in a part wherein the groove 226 is formed. <P>COPYRIGHT: (C)2004,JPO&NCIPI
