Abstract
Abstract This present invention relates to a spray head for spray diffusers of liquids, powders, and the like. This spray head consists of three separable parts mounted together to form an air-admission chamber between them. The head has an internal groove for collecting traces of the spray products after each spraying operation, such that the product does not flow down the side of the head and the diffuser to render the diffuser inoperative.
