ABSTRACT:
Equipment for manufacturing a polyethylene terephthalate container which is capable of withstanding, without appreciable deformation, relatively severe thermal conditions encountered during processing by filling with a hot liquid or pasteurization of the contents of the container. The equipment includes a first mold which is designed to shape the body of an intermediate container from the body of an amorphous polyethylene terephthalate preform to a size larger than the dimensions of the final container to be obtained. Second, the equipment includes a treatment station which itself includes a first heating device which simultaneously heats the body and neck section of the intermediate container to a temperature of about 160.degree. to about 240.degree. C. to rapidly shrink the body of the intermediate container and to effect crystallization of the neck section and increase the crystallinity of the contracted intermediate container body. The treatment station then slowly cools the contracted intermediate container body and the neck section, whereafter a second heating device heats the contracted intermediate container prior to placing it in a second mold. The second mold has dimensions corresponding to the final size of the container to be obtained.
