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.

A method of manufacturing a composite container mounted with a label on a trunk, the method comprising:
- providing the label and a preform, and providing a molding die having a first mold for molding an upper part of the composite container and a second mold for molding a lower part of the composite container, the first mold including a plurality of split-mold segments;
- arranging the label in the second mold, and arranging the preform between the split-mold segments of the first mold;
- after arranging the label and the preform, closing the molding die, closing of the molding die including moving one of the split-mold segments in a first direction toward the other of the split-mild segments, closing of the molding die also including moving one of the first mold and the second mold in a second direction toward the other of the first mold and the second mold, the first direction being different from the second direction;
- blow molding the preform in the closed the molding die;
- and
- opening the molding die removing the composite container from the molding die.
A molding die for forming a composite container provided with a paper label on a trunk, the molding die comprising:
- a second mold in the form of a unitary closed cylinder and having a label arranged on an inside thereof, the second mold defining a central axis, and a first mold, the first mold including a plurality of split-mold segments, the split mold segments arranged to receive a preform between the split mold segments from a direction that laterally intersects the central axis of the second mold.
