Abstract
A lightweight finish for a hot-fill container uses less material compared to existing hot-fill container finishes. The lightweight finish yields a cost savings while still providing adequate dimensional stability to allow the container to maintain its shape during the hot-fill process.

A lightweight finish for a hot-fill container comprising an outer surface having an annular lower flange, an annular upper flange, and threads located above the annular upper flange, wherein the finish has a weight of from about 3.5 to about 8 g, and wherein the annular lower flange has a thickness “A” of from about 0.2 to about 0.25 inches, and a height “B” of from about 0.05 to about 0.08 inches.
A lightweight finish, for a hot-fill container comprising an outer surface having an annular lower flange, an annular upper flange, and threads located above the annular upper flange, wherein the finish has a weight of from about 3.5 to about 8 g, wherein the annular upper flange projects from the outer surface of the finish at a distance “C” of from about 0.025 to about 0.055 inches, and has a height “D” of from about 0.06 to about 0.1 inches.
A lightweight finish, for a hot-fill container comprising an outer surface having an annular lower flange, an annular upper flange, and threads located above the annular upper flange, wherein the finish has a weight of from about 3.5 to about 8 g, wherein each of the threads projects from the outer surface of the finish at a distance “G” of from about 0.025 to about 0.055 inches, and has a height “F” of from about 0.04 to about 0.08 inches.
A lightweight finish for a hot-fill container comprising:
- an outer surface having an annular lower flange having a thickness “A” of from about 0.2 to about 0.25 inches, and a height “B” of from about 0.05 to about 0.08 inches;
- an annular upper flange which projects from the outer surface of the finish at a distance “C” of from about 0.025 to about 0.055 inches, wherein the annular upper flange has a height “D” of from about 0.06 to about 0.1 inches;
- and
- threads located above the annular upper flange, wherein each of the threads projects from the outer surface of the finish at a distance “G” of from about 0.025 to about 0.055 inches, and has a height “F” of from about 0.04 to about 0.08 inches.
