Abstract
Provided is a method for manufacturing a container containing a content fluid, including: a molding step of stretching a bottomed tubular preform that is heated to a temperature at which the preform is stretchable so as to form the container by means of pressure of the content fluid injected into the preform through a mouth portion; a sealing step of sealing the content fluid by fitting a cap body to the mouth portion; and a pressurizing step of increasing an inner pressure of the container, wherein the container includes an invertible deforming portion that is freely invertible and deformable toward an inside of the container, and in the pressurizing step, the inner pressure of the container is increased by reducing a volume of the container by inverting and deforming the invertible deforming portion toward the inside of the container.
