Abstract
A blow-molded plastic container includes an upper portion having a finish, a body portion and a base. At least one groove is formed in a radial sidewall of the finish. The groove slopes gradually downward along the radial sidewall and away from an opening into the container. A method of making the blow-molded plastic container includes disposing a preform into a mold cavity having a surface defining a body forming region, a finish forming region and a moil forming region. The preform is blown against the mold surface to form an intermediate container having a body portion, a finish and a moil portion. The moil is severed from the finish to define the opening into the container. A closure member is adapted to selectively mate with the finish on the container. At least one thread is formed on the closure member.
