Patent ID: 8468785

Claim:
A process for manufacturing and hot-filling a PET container comprising the following steps: a) providing a PET preform capable of being blow molded according to a conventional process which is not a heat resistant process, b) blow molding the preform in a cavity of a mold so as to form a container; c) removing the container from the mold cavity; d) filling the container with a liquid, the temperature of which is above 80° C.; e) sealing the container in a leaktight fashion; f) sterilizing and cooling the container; and g) shrinking the container, wherein: in step a) a PET preform composed of a copolymer based on terephthalic acid is used; in step a), at least one part of the preform is at a temperature greater than or equal to 110° C.; the temperature of the mold used in step b) is less than or equal to 65° C.; and during step g) the container is heated for a duration between 1 and 5 seconds at a temperature between 600 and 1000° C. in at least one part of the container so as to create a shrinkage and a reduction in the volume of the container.
