<p>An assembly (10) for dispensing agents into drains and the like, includes a retaining member (12) having a perforate wall structure (20) substantially surrounding and enclosing a quantity of a sanitizing agent therein. The retaining member (12) is preferably flexible and tubular, and may be formed into a donut-shaped configuration. The retaining member (12) may be provided of a mesh material (24). The mesh initially holds the sanitizing agent, provided as a powder or in a granular form therein. Upon wetting of the sanitizing agent, it may assume a gel-like consistency and erode to dispense the sanitizing agent into the liquid passing through the retaining member (12). A mount (16) may be employed to both hold the retaining member (12) in a proper position and configuration, and to secure edges of the retaining member (12) in a closed position.</p> |
