ABSTRACT:
A method for producing an integral bottle/collar combination for use in a package for storing and dispensing potentially dangerous material such as medicament tablets. The package is resistant to opening by children yet readily openable by adults. The process includes a step of injection molding a polymeric part having a finish portion, a preform portion, and a flange portion. The flange portion has at least one integrally formed socket having a resiliently deformable pushtab connected by a hinge. The preform portion of the injection molded part is blow molded into the shape of the bottle. The hingedly connected pushtab is then folded into its in-use position.
