Abstract:
A method for manufacturing a resin container part includes: injection-molding of a bottomed resin preform including, on a bottom portion thereof, a thick bulging portion that retains residual heat by which the bulging portion is deformable by being pressed to follow a shape of a blow cavity mold; and a blowing including stretching a body portion of the preform by applying a blow pressure to the preform and forming a joint portion by pressing the bulging portion of the preform with an upper bottom mold to deform the bulging portion to follow the shape of the blow cavity mold.
