<P>PROBLEM TO BE SOLVED: To provide a novel manufacturing method of a multilayer bottle product, which facilitates filling with a content liquid-tightly. <P>SOLUTION: There is provided the manufacturing method of a multilayer bottle product 10 which includes: a bottomed cylindrical outer bottle 11; a flexible inner bottle 12 having substantially the same shape as the inner surface of the outer bottle 11 and stored in the outer bottle 11; a lid body 13 closing the mouth of the inner bottle 12 and the mouth of the outer bottle 11; a content A filling the gap between the outer bottle 11 and the inner bottle 12; and a propellant B filling the inner bottle 11. With the inner bottle 12 inserted in the outer bottle 11, the gap between the outer bottle 11 and the inner bottle 12 is filled with the content, while causing the inner bottle 12 to be deformed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
