Abstract: Blow molding tools and a method of blow molding which provide that the tool have a retractable push up section in the base which allows for the article molded by the tool to have a recessed base internal to an otherwise hollow structure. As the push up is moveable, adjustment of the push up portion can be performed during an automated blow molding operation so as to allow release of the blow molded article.

Abstract: A container which includes a recessed portion and a complimentary top and base of generally undulating design which allow for a stack of such containers to be arranged where the neck of a lower container is placed within the recessed portion of an upper container and the base of the upper container contacts the top of the lower container. The container stack can then be extended to comprise multiple stacks which are positioned on a shipping pallet to provide for improved transportation efficiency of palletized containers.

Abstract: A conditioning station for conditioning a blow mold preform which includes a heating element for the base of the preform. The conditioning section may also include other heating elements for heating a variety of locations of the preform. The elements are generally arranged so that at least one heat ring is arranged below the preform. The lower preform will generally have a reduced diameter compared to the circumference of the preform. There can also be an element in a moveable position which can adjust position about the side walls of the preform.
