Abstract:

In a first respect this invention is a container, comprising: a cylindrical, hollow body capped on both ends by a base and a top; a conduit that bisects the top and extends into the interior of the container; and a perforated housing that encompasses the portion of the conduit that extends into the interior of the container. In another broad respect, this invention is a removable splash guard, comprising: a housing having a top and bottom that define an internal space; a lower tube that bisects the bottom, wherein the lower tube has a upper portion which is angled; an upper tube that bisects the top, wherein a portion of the second tube that extends into the internal space contains at least one hole; and a partition interposed between the upper and lower tubes that serves to block movement of a chemical from the lower tube to the opening at the inboard end of the upper tube. In another respect, this invention incorporates a flow restrictor of any type or material into the inlet or outlet tubing to reduce the pressurization or de-pressurization steps in a line drain sequence.
