Abstract:
1. A mold assembly for blow molding at least one container from a tubular extrusion, the container characterized by: (i) a container body; (ii) a base for supporting the container body in an upright position; and (iii) a neck including a mouth opening and having surface features for engaging a separable closure for covering the mouth and a transfer ring open to the interior of the container body and comprising a top ring surface joined to the neck, a bottom ring surface joined to the container body and a sidewall defining the outer perimeter of the transfer ring and being joined to the top ring surface and the bottom ring surface, the transfer ring projecting outside the periphery of the container body at the junction of the bottom ring surface and container body and characterized by a plurality of arcuate recesses in the sidewall disposed to reduce deformation at the junction of the top ring surface and neck resulting from compressive forces acting on the neck along the longitudinal axis of the container, the mold assembly comprising first and second mating mold components, each mating mold component comprising molding surfaces open to a mating face of the mold component and defining the exterior of an article to be molded, the molding surfaces comprising first molding surfaces defining the container body, second molding surfaces defining the neck of the container and third molding surfaces defining the base of the container.
