Abstract: A PET preform from which a container of a desired shape can be accurately molded by liquid blow molding. A configuration is adopted where the preform has a bottomed cylinder shape provided with a mouth portion and a body portion and, when molded by liquid blow molding into a container, the body portion is stretched in an axial direction at a stretch ratio of 1.50 or more and 3.10 or less and is stretched in a radial direction at a stretch ratio of 2.26 or more and 3.70 or less.

Abstract: A preform formed from polypropylene or high density polyethylene and with which a container of a desired shape can be precisely molded by liquid blow molding. When formed of polypropylene as a closed-bottom cylinder shape having an open end section and a body section, the preform is molded into the container by stretching the body section in the axial direction by a stretch ratio of 2.25-4.34, inclusive, and in the radial direction by a stretch ratio of 1.95-5.00, inclusive. When formed of high density polyethylene as a closed-bottom cylinder shape having an open end section and a body section, the preform is molded into the container by stretching the body section in the axial direction by a stretch ratio of 1.69-2.50, inclusive, and in the radial direction by a stretch ratio of 2.26-5.07, inclusive.

Abstract: A method of manufacturing a composite container. The method includes providing a paper label, and a preform; providing a molding die equipped with a closed, cylindrical lower mold and an upper mold composed of a plurality of split-mold segments; arranging the paper label in the lower mold; arranging the preform between opened split-mold segments; moving one or both of the lower mold with the paper label and the upper mold with the preform in a direction towards each other to close the molding die; implementing blow-molding on the preform in the molding die; and opening the molding die to release the composite container.
