1. A method for producing a composite container, the method comprising the steps of:
preparing a preform made of a plastic material;
preparing a plastic member comprising a heat-contracting tube;
disposing the plastic member on an outside of the preform to surround the outside of the preform;
disposing a print region on a surface of the plastic member;
performing a first heating process of directly heating the preform and the plastic member together by a first heating apparatus, whereby the plastic member heat contracts to contact the outside of the preform to form the composite preform;
performing a second heating process of heating the composite preform, formed by the first heating process, by a second heating apparatus, which is different from the first heating apparatus, before inserting the composite preform, which has been heated by the second heating apparatus, into a blow molding die of a blow molding apparatus; and
integrally inflating the composite preform, including the preform and the plastic member, by performing blow molding on the composite preform in the blow molding die to form a composite container,
wherein the first heating process of forming the composite preform is performed in a first factory, which is different from a second factory where the second heating process and the process of forming the composite container by the blow molding are both performed, so that the composite preform, including the preform and the plastic member that is heat contracted to contact the outside of the preform, is delivered from the first factory to the second factory without the plastic member of the composite preform slipping from the preform of the composite preform during delivery,
wherein the plastic member comprises a blow tube made by blow molding, an injection molded tube made by injection molding, or an inflation-molded tube made by shaping a resin sheet, and wherein the plastic member has a cylindrical trunk part,
wherein the first heating process is performed by the first heating apparatus at a temperature in a range of 50° C. to 80° C., and
wherein the second heating process is performed by the second heating apparatus, which is included in the blow molding apparatus, at a temperature in a range of 90° C. to 130° C., and which is higher than the temperature of the first heating process.
