<P>PROBLEM TO BE SOLVED: To propose a container which is so manufactured inexpensively and easily by blow molding, etc., that a trunk and a spout 6 are formed integrally, a delivery path of the spout 6 is blocked liquid-tightly even if unsealed once, to allow partial use of contents, and to enable stable storage of the contents after unsealing. <P>SOLUTION: The spout 6 is provided with a delivery valve A on its intermediate part. The delivery valve A is a hollow body having a pair of a tray-like board 11 and a tray-like reversing board 12, which are divided by an annular folding line 10 as a boundary. The board 11 opens an exit 13 on the base end part 6a of the spout 6 and an entrance 14 on the front end part 6b of the spout 6. When the delivery valve A is depressed to reverse the reversing board 12 inwardly, the reversing board 12 blocks the exit 13 and the entrance 14. The reversing board 12 is reversed and pushed outwardly by liquid pressure to allow the valve A to deliver the contents. <P>COPYRIGHT: (C)2007,JPO&INPIT |
