Abstract

An anti-crossover nozzle with two principle pieces that snap together, having a forward end portion (78) with a dispensing opening (74), a rear end portion (72) which includes at least a pair of inlets (62, 63), each inlet having a center passage (98, 100) therethrough, at least two valve leaflets (92, 94) biased by thei own inherent resiliency to a normally closed position and covering openings in said passages (98, 100) afforded by said inlets (62, 63), and at least one point of attachment (97) formed between an interior surface of the rear end portion (72) and said valve leaflets (92, 94), said leaflets (92, 94) being able to be displaced from their normally closed position by the force of incoming liquid foam components.
