The invention comprises a novel apparatus for delivering a nutritive substance comprising a container body having a base at one end thereof, an upper portion adapted for removable receipt of a closure, the upper portion defining an opening therein, and a chamber defined by the container body, the chamber being in fluid communication with the upper portion opening. In a preferred manner, the aqueous solution is introduced into the drain employing a hose end dispensing device having a foam producing nozzle. The wiring portion is provided with a lower layer wiring portion that is disposed in the same layer as the comb-shaped electrode and an upper layer wiring portion that is disposed on the lower layer wiring portion. Frequently, the zippers are hard to operate.
