ABSTRACT:
A blown plastic container that includes a hollow plastic body, an integral blow-molded neck and an integral blow-molded finish with a radially outwardly extending blow-molded thread or bead for retaining a closure on the finish. Reinforcement is provided between the thread or bead and a ledge on the finish to prevent collapse of the finish when a closure is applied to the finish. In one form, this reinforcement includes blow-molded axial columns extending radially outwardly. In another form, the reinforcement includes geometric depressions. Preferably, the reinforcement is disposed circumferentially at equal spacing. When the container is trimmed, the finish may have an annular frustoconical radial ledge spaced form the open end of the finish. The reinforcement extends between the ledge and the lowest thread or bead, between the thread or bead, or for the full height of the finish above the ledge.
