Beschreibung
Zusammenfassung:	A product is disclosed for inverted spray dispensing of material that comprises at least some particulate matter. The dispensing end of the container is connected to a valve, which includes a valve that moves from a biased closed position to an open position to discharge the product downward through the valve, when the dispensing end of the container is directed downward. An inlet end of the valve is spaced vertically above the dispensing end of the container when the dispensing end of the container is directed downward. The inlet end of the valve or spring cup is connected to a mesh filter having a pore size at least as large as an average diameter of the solid particles. Even when the container is inverted and a layer of settled particles forms at the dispensing end of the container, valve and mesh filter are designed so that at a portion of the proximal end of the mesh filter is disposed above the layer of settled particles to prevent clogging of the mesh filter.
