Problems solved by technology

Also, when the trigger sprayer is finished, the cover is sometimes not fully rotated to the closed position
This can cause the stored liquid to leak from the trigger sprayer when the trigger sprayer is tipped over

Embodiment Construction

[0028] The trigger sprayer of the present invention features a novel indexed nozzle assembly that can be used with various types of trigger sprayers. The indexed nozzle assembly of the present invention allows the liquid discharge pattern of the trigger sprayer to be varied between an off position, a spray position, or a flow out position. The unique features of the indexed nozzle assembly can be applied to various types of hand-held and manual trigger sprayers. Figure 7 shows an example of a trigger sprayer 12 that may employ the indexed nozzle assembly 14 of the present invention. However, it will be appreciated that the trigger sprayer 12 shown in FIG. 7 is but one example of a trigger sprayer that may employ the indexed nozzle assembly 14 of the present invention. Since the operation of the indexed nozzle assembly 14 does not require any particular configuration of the trigger sprayer, only the trigger sprayer 12 of FIG. 7 will be generally described herein.

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.

Description

technical field [0001] The present invention relates to a hand-held and hand-operated liquid sprayer commonly known as a trigger sprayer. In particular, the present invention relates to an indexed nozzle assembly for a trigger sprayer having a manually rotatable cover mounted for rotation on a liquid dispenser of the nozzle assembly. Rotation of the cover changes the nozzle assembly between a closed position in which liquid is expelled from the orifice of the nozzle assembly, a spray position, a second closed position, and an outflow position with one successive rotation of the cover. In addition, the spaced relationship between the end surface of the liquid dispenser and the inner wall of the cover surrounding the discharge orifice enhances the shape of the liquid stream discharged by the nozzle assembly. Background technique [0002] Hand-held and manual liquid sprayers are generally referred to as trigger sprayers as they are known in the liquid sprayer art. Trigger spr...
