Abstract
An indexing nozzle assembly for a trigger sprayer has a manually rotatable cap mounted for rotation on a liquid spinner of the nozzle assembly. Rotation of a cap changes the nozzle assembly between an off condition, a spray condition, a second off condition, and a stream condition of the liquid discharged from the nozzle assembly. The cap can be rotated from the off position directly to either of the spray or stream positions by rotating the cap one-quarter turn in opposite directions. A spatial relationship between an end surface of the liquid spinner and an interior surface of the cap end wall that surrounds the assembly discharge orifice improves the stream configuration of liquid discharged by the nozzle assembly.
Claims16
A trigger sprayer comprising:
- a manually operated pump on the trigger sprayer;
- a nozzle cap on the trigger sprayer, the nozzle cap having an end wall with an exterior surface and an opposite interior surface, a discharge orifice extending through the end wall and intersecting the exterior surface and the interior surface, the discharge orifice having a center axis and the nozzle cap being rotatable on the trigger sprayer about the center axis;
- a liquid discharge passage extending through the trigger sprayer from the pump to the discharge orifice;
- a liquid spinner positioned in the liquid discharge passage adjacent the nozzle cap interior surface and the discharge orifice with an axial spacing between the liquid spinner and the nozzle cap interior surface.
A trigger sprayer comprising:
- a manually operated pump on the trigger sprayer;
- a nozzle cap on the trigger sprayer, the nozzle cap having a discharge orifice with a center axis, the discharge orifice extending between an exterior surface of the nozzle cap and an interior surface of the nozzle cap inside the trigger sprayer;
- a liquid discharge passage extending through the trigger sprayer from the pump to the discharge orifice;
- and
- a liquid spinner positioned in the liquid discharge passage adjacent the nozzle cap interior surface, the liquid spinner having a length that extends along a portion of the liquid discharge passage to an end surface of the liquid spinner that opposes the nozzle cap interior surface, a swirl chamber cavity is recessed into the end surface and the end surface is spaced from the nozzle cap interior surface.
