Abstract: The invention is an improved lightweight container and method for manufacturing the same. The container incorporates a thinner wall structure in an essentially octagonal container having a bottom member, a plurality of sidewalls, a spout, an upwardly converging neck member coupling the sidewalls of the spout, a handle molded into the container and a radiused transiting section between the sidewalls and the spout which eliminates weakened corner sections and improves overall strength to weight ratios. Also disclosed is a method of forming the container to achieve the above-described result.

Abstract: The present invention provides a molding machine and a mold assembly having a quick change volume control insert. The volume control insert can be changed without disassembly of the mold or use of special tools. The molding machine includes a mold, a mold insert, a locking member, and a release member. The mold insert is received in one of the mold halves and further includes a mold detail defining a portion of the mold cavity, and a retention member. A locking member engages the retention member when the mold detail is received within the mold half. The release member, accessible from the exterior of the mold half, and is adapted to disengage the locking member from the retention member, allowing the mold detail to be removed.
