ABSTRACT:
A manually-actuated spray head for a liquid container includes a housing within which an insert is provided to establish a liquid flow path through the housing. One end of the insert is compressed by the housing to form a nozzle through which liquid is dispensed from the spray head. The other end of the insert is provided with a flange for sealing engagement with the container. A rotor rotatably driven by a user-actuated trigger compresses the center portion of the insert to force liquids through the nozzle under pressure. Since the entire liquid flow path of the spray head is defined by a replaceable insert construction of the housing is simplified and contamination of subsequently sprayed liquids can be avoided by changing the insert.
