<P>PROBLEM TO BE SOLVED: To make it difficult for hydrogen in a pouch for hydrogen containing drink to penetrate and leak out through a straw or a cap. <P>SOLUTION: In forming this pouch for hydrogen containing drink, a synthetic resin formed straw 2 is passed through and welded to a bag shaped container 1 made of soft packaging sheets, the inside end 15 of the straw is opened to the inside of the container, the outside end 16 of the straw is opened to the outside of the container, the outside end of the straw is covered with a cap 3 and the cap is tightened to close the outside end of the straw. The inner peripheral side of the tubular straw is made of a hydrogen blocking resin 31 and the outer peripheral side of the same is made of a weldable and sturdy resin 32. The welding face of the soft packaging sheets 11, 12 forming the container is made of a resin weldable relative to the resin used for the outer peripheral side of the straw. The inner face of the cap is formed with a hydrogen blocking resin 36 layer and the hydrogen blocking resin layer covers the outside end opening of the straw to close. Other part of the same is made of a sturdy resin 37. <P>COPYRIGHT: (C)2010,JPO&INPIT |
