Abstract
A method for providing a thermally stable finish in a plastic container. A finish section is reformed, which in part requires crystallizing a portion of the finish. The finish section has a finish dimension that shrinks to an intermediate finish dimension. Thereafter, the crystallized finish is annealed such that the intermediate finish dimension conforms to a predetermined range.
Claims19
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;
- engaging a closure with said finish section:
- and
- annealing said crystallized finish such that said intermediate finish dimension conforms to a predetermined target dimensional value.
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, wherein said crystallization is accomplished by a constrained process;
- engaging a closure with said finish section;
- and
- annealing said crystallized finish such that said intermediate finish dimension conforms to a predetermined target dimensional value.
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, wherein said crystallization is accomplished by a free process;
- engaging a closure with said finish section;
- and
- annealing said crystallized finish such that said intermediate finish dimension conforms to a predetermined target dimensional value.
