Benefits of technology

[0010] According to an exemplary embodiment of the instant invention, a finish of a plastic container is provided and may include an annular rib for increasing the rigidity of said

Problems solved by technology

Without such rigidity, the finish may be more prone to deflection such as, for example, ovalization, in a variety of settings.
Without the necessary rigidity, the finish is likely to deflect during such attachment and a poor seal can result.
Likewise, during cooling of a container (if hot-filled), a finish without the necessary rigidity may deflect and create sealing issues.
Furthermore, finishes that lack rigidity might flex when squeezed or dropped during handling again resulting in improper sealing between the finish and the closure.
Each of the aforementioned scenarios can thus result in spoilage of the contents of the container because of the poor seal.
Container finishes such as, for example, blown wide-mouth finishes, may often be excessive
