Abstract
An aspiration sprayer comprises a head which is permanently attached to the container in which the additive material is received and which is movable between a first position in which the interior of the container is sealed and a second position in which the interior of the container is unsealed and aspiration occurs, the making of seals and appropriate fluid connecitions being accomplished by a plurality of sealed cups moved by the head. Safety means are provided to tend to retain the head in its container-sealing position. An aspiration opening is accessed by means of a nozzle which is snap-engaged with the head, and the carrier fluid after it leaves the nozzle is guided by means of flanges on the head so located and oriented as to produce a long-distance jet output. A cover protects the parts from accumulation of foreign matter.
