ABSTRACT:
A system is provided for filling, for purifying liquids in a shipping container and for maintaining the high purity during withdrawal from the bulk shipping container of liquids, such as high purity liquids. In the system a specially designed bung adapted to fit shipping containers, such as pails and drums which may be made of a suitable plastic, metal, e.g. stainless steel, or other material of construction. The special bung has at least two openings, including an opening into which is fitted a dip tube that reaches contiguous to the bottom of the container. The special bung also has an opening into which a gas filter can be secured. In the system, the contents of the container can be pumped through the dip tube while maintaining the integrity of the product against contamination. The purity of the liquid can be upgraded by pumping, i.e., recirculating the liquid through a filtration media and returned to the container. A gas filter to purify air or vapor passing into or out of the container avoid pressure or vacuum buildup. Both openings in the bung are fitted with plugs to seal the container during the shipment of the filled containers. Containers fitted with the special bung are designed for repeated use, i.e., returnable containers, and each container is preferably dedicated to the packaging of only a single high purity liquid chemical product.
