することを目的とする。However, because glass containers are heavy and bulky, the amount that can be transported from the container manufacturer to the liquid filler at one time is limited, which increases transportation costs, makes handling difficult, and even causes damage during transportation. Or, after filling with liquid, the container could break and the contents could leak out. In order to solve this problem, plastic containers are now increasingly being used. However, plastic containers also have the following problems. In other words, current plastic containers are manufactured by blow molding or injection molding, and are transported from container manufacturers to liquid filling companies as finished containers molded into a predetermined shape, so they are light in weight but bulky. As a result, the quantity that can be transported at one time is limited, resulting in high transportation costs.Furthermore, since it is molded using the above-mentioned molding method, it is impossible to mold it using laminates of different materials. However, it has not been possible to produce containers that are excellent in gas permeation prevention properties, heat resistance, etc., especially containers that contain food contents and have excellent gas permeation prevention properties, heat resistance, etc. OBJECTS OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide an apparatus capable of manufacturing a plastic container containing contents from a low-bulk container blank.
