Abstract
A method for providing a thermally processed commodity in a plastic container. The container is exposed to elevated temperatures to form an -intermediate finish section. A commodity is dispensed within the plastic container. A closure engages the intermediate finish section. The container and the commodity are thermally processed. The finish section being within a predetermined range whereby the finish section and the closure result in retaining a hermetic seal.
Claims34
A method of providing a thermally processed commodity retained within a plastic container, said method comprising:
- providing a container having an initial finish section;
- reforming said container, thereby forming an intermediate finish section;
- dispensing a commodity within said container;
- engaging a closure with said intermediate finish section;
- and
- thermally processing the commodity within said container such that said intermediate finish section remains within a predetermined range, whereby a finish section and said closure seal said container.
A plastic container system adapted for retaining a commodity during and after a thermal process, said system comprising:
- a container having an engagement member that is exposed to elevated temperatures to form an intermediate engagement member having a predetermined diameter;
- and
- a closure member cooperatively engaging said plastic container, said closure member engaging said intermediate engagement member to form a hermetic seal, said closure member and said intermediate engagement member cooperating to require a first torque to remove said closure from said container before thermal processing and to require a second torque to remove said closure from said container after thermal processing, said first torque being substantially equal to said second torque.
A method for providing a thermally processed commodity within a plastic container, said method comprising:
- providing a container having an initial finish section;
- exposing said initial finish section to thermal energy such that said initial finish sections shrinks to an intermediate finish section;
- dispensing a commodity within said container;
- engaging a closure with said intermediate finish section;
- and
- thermally processing the commodity within said container, said intermediate finish section having a diameter which remains within a predetermined range, whereby a finish section and said closure seal said container.
A method of providing a thermally processed commodity retained within a plastic container, said method comprising:
- providing a preform having an initial finish section;
- reforming said preform, thereby forming a preform having an intermediate finish section;
- molding said preform, thereby forming a container;
- dispensing a commodity within said container;
- engaging a closure with said intermediate finish section;
- and
- thermally processing the commodity within said container such that said intermediate finish section remains within a predetermined range, whereby a finish section and said closure seal said container.
A method for providing a thermally stable finish, said method comprising:
- providing a finish section;
- reforming said finish section, which in part requires crystallizing at least a portion of said finish such that said finish has a finish dimension that shrinks to an intermediate finish dimension;
- annealing said crystallized finish such that said intermediate finish dimension conforms to a predetermined range.
