WIPO Patent Application WO/2020/162032
Kind Code:
A1
Abstract:
A pressurized fluid that is introduced from a passage 4 into a space between an outer bottle body 24 and an inner container body 31 causes the inner container body 31 to be deformed and be reduced in volume so as to form a space between the inner container body 31 and the outer bottle body 24. When doing so, a stopper rod 82 is inserted into the interior of the inner container body 31 through an inner mouth portion 30 before the deformation of the inner container body 31 starts so as to cause the stopper rod 82 to come into contact with and become fixed to the bottom portion of the inner container body 31.
