Abstract
An aspiration sprayer comprises a head which is preferably permanently attached to a container in which additive material is received. The head may or may not be movable between positions controlling the degree of aspiration affected, and is provided with a cap movable between a first position in which the cap seals the container and prevents the additive material from escaping therefrom and a second position in which the container is unsealed and aspiration of the contents thereof can take place. Elements may be provided as part of the sprayer assembly for controlling the flow of the aspirating fluid. The cap is secured in its sealing position by an element which requires special manipulation for release, thereby providing an important safety feature.
