PROBLEM TO BE SOLVED: To provide a manufacturing method which can easily manufacture a contents-containing double chamber container which can keep sealability without being easily opened before use and can be easily opened by a simple operation when it is used, in a container which is divided with an easily openable seal and has one or a plurality of chambers in which fillers are sealed.;SOLUTION: In the method for manufacturing the easily openable contents-containing double chamber container 1, a process for forming a sheet formation A4 with a recessed part 2, a process for filling the contents in the recessed part 2, and a process for covering a recessed part 2 side of the sheet forming article A4 with a sheet formation B5, are successively performed. Then, the method comprises a process wherein two sheet formations 4 and 5 are sealed by a recessed part seal 6, which is an example of an easily openable recessed part sealing means, in the vicinity of the recessed part 2, or a process wherein two sheet formations 4 and 5 are sealed by a peripheral edge seal 7, which is an example of a hardly openable sealing means and is not easily openable, enclosing and surrounding one or a plurality of chambers sealed by the recessed part seal 6 on the outside of the recessed part seal 6.;COPYRIGHT: (C)2005,JPO&NCIPI
