Abstract
The invention features, in general, a foaming product that includes a container, a valve stem extending upward from the top of the container, a nozzle member, and a waste product containment region located above the top of the container. The valve stem is movable downward to permit discharge of the foaming product from the container through the stem. The nozzle member includes a flow passage for directing the foaming product from the top of the valve stem to a discharge outlet and a movable portion that is movable between a discharge position and an inactive position. When the movable portion is in the discharge position, the valve stem is actuated to permit discharge of product into the flow passage and out of the discharge outlet, and the flow passage does not communicate with the containment region. When the movable portion is in the inactive position, the valve is not actuated, and the flow passage communicates with the waste product containment region such that undischarged foaming product in the flow channel is directed to the waste product containment region.
