Abstract
An anti-crossover nozzle with two principle pieces that snap together, having a forward end portion with a dispensing opening, a rear end portion which includes at least a pair of inlets. Each inlet has a center passage, therethrough and at least two valve leaflets biased by their own inherent resiliency to a normally closed position covering openings in the passages. There is at least one point of attachment formed between an interior surface of the rear end portion and the valve leaflets. The leaflets are displaced from their normally closed position by the force of incoming liquid foam components.
