Abstract
A container assembly including a container and a metallic closure. The container includes a polymeric body and a polymeric finish. The polymeric finish includes a plurality of threads. A lug lock is associated with each one of the plurality of threads. The metallic closure includes at least three metallic lugs configured to cooperate with the plurality of threads to couple the metallic closure to the polymeric finish.
Claims40
A container assembly comprising:
- a container including a polymeric body and a polymeric finish, the polymeric finish including a plurality of threads;
- a metallic closure including a base and a sidewall extending from the base, the sidewall including a rim at an end of the sidewall opposite to the base, the rim including at least three metallic lugs configured to cooperate with the plurality of threads to couple the metallic closure to the polymeric finish;
- and
- a lug lock associated with each one of the plurality of threads;
- wherein the polymeric finish includes a plurality of strengthening members that extend from an exterior surface of the finish, one of the plurality of strengthening members is integral with a trailing end of each one of the plurality of threads, the strengthening members provide a stop for the metallic lugs to prevent the metallic lugs from moving along the threads past the strengthening members and center the metallic lugs along the threads with respect to an upper surface of the threads;
- wherein the container is filled with a material at a temperature in a range of 50° F.-250° F.;
- wherein the polymeric finish is a crystallized finish of about 25% to about 35%;
- wherein the lug lock includes a plurality of ribs at an undersurface of each one of the plurality of threads;
- and
- wherein when the metallic closure is coupled to the container, each one of the metallic lugs is configured to simultaneously contact only one of the threads and at least one of the lug locks.
