Abstract
A spray nozzle assembly composed of a support member defining a product flow path for conducting a flowable product which is to exit the nozzle assembly in the form of a spray; a spray nozzle member providing a spray opening communicating with the flow path, the spray nozzle member being operative for emitting the flowable product from the spray opening in a form determined by the size and shape of the spray opening; and a holding member for holding the spray nozzle member in position relative to the support member, wherein the spray nozzle member is made of an elastic material which is deformable in a manner to vary the size of the spray opening, and the holding member is movable relative to the support member for deforming the elastic material of the spray nozzle member to vary the size of the spray opening.
Claims19
A spray nozzle assembly comprising:
- a support member defining a product flow path for conducting a flowable product which is to exit the nozzle assembly in the form of a spray;
- a spray nozzle member providing a single spray opening communicating with the flow path, said spray nozzle member being operative for emitting the flowable product from the spray opening in a form determined by the size and shape of the spray opening;
- and
- a holding member for holding said spray nozzle member in position relative to said support member,
- wherein said spray nozzle member comprises an elastic material which is deformable in a manner to vary the size of the spray opening, and said holding member contacts said spray nozzle member uniformly in a circumferential direction around said spray opening and is movable relative to said support member to apply a deforming force in a direction parallel to the direction in which the flowable product is emitted from the spray opening for deforming the elastic material of said spray nozzle member to vary the size of the spray opening.
