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.

Abstract: A manually operated liquid foaming dispenser is attached to the top of a container of liquid and is manually vertically reciprocated to dispense the liquid from the container as a foam. The dispenser includes a liquid pump chamber and an air pump chamber that respectively pump liquid and air to a discharge passage of the pump where the liquid and air are mixed, generating the foam dispensed from the dispenser. The liquid dispenser is constructed with three biased closed valves that prevent leakage from a liquid container attached to the dispenser should the dispenser and container be positioned on their sides or be inverted.

Abstract: A liquid dispensing, manually operated trigger sprayer has a trigger with an ergonomic finger engagement surface. The trigger finger engagement surface extends longitudinally across the front of the trigger and has a protrusion at the top of the surface. The protrusion has a finger engagement surface portion that rests on the top of a finger of a user's hand while the user's hand manipulates the trigger of the trigger sprayer.

Abstract: The present invention pertains to a trigger sprayer which is connectable to two container volumes containing separate liquids. The sprayer has a trigger that is manipulated to draw the separate liquids into two separate pump chambers and then supply the two separate liquids from the pump chambers through two separate discharge passages and check valves to a mixing chamber of the sprayer. In the mixing chamber the two separate liquids are mixed together prior to their being dispensed from the trigger spray.

Abstract: A manually operated liquid foaming dispenser is attached to a bottle of liquid and pumps and mixes both the liquid and air to create a foam from the liquid and to dispense the foam. The dispenser includes a pump housing containing an air pump chamber and a liquid pump chamber, and a pump plunger that is manually reciprocated in both the air pump chamber and the liquid pump chamber. An air piston and a liquid piston are mounted on the plunger and are reciprocated by the plunger in the respective air pump chamber and liquid pump chamber. The air piston is mounted on the pump plunger for relative movement of the air piston on the plunger that enables an interior volume of the air pump chamber to be vented to an exterior environment of the dispenser on manual reciprocation of the pump plunger.

Abstract: A liquid dispensing assembly includes a hand-operated trigger sprayer that is removably attached to a bottle container and communicates with the bottle container through a length of conduit. The trigger sprayer can be securely attached to the bottle container by a child proof connection with the length of conduit stored in an interior volume of the handle of the trigger sprayer or with the length of conduit positioned on the exterior of the trigger sprayer handle and the bottle container.

Abstract: A child resistant closure apparatus between a container and a cap comprises a separate safety lock ring. The lock ring is mounted over the container neck and the cap is mounted on the container neck and engages with a pair of lock clasps on opposite sides of the lock ring. Finger pads on opposite sides of the lock ring are squeezed and compressed by one hand of the user while the cap is rotated on the container neck by the other hand of the user to separate the cap from the container. The lock ring is designed to be employed with container and cap closure assemblies of at least two different sizes, reducing their manufacturing costs. Additionally, the lock ring may be removed from the container if it is desired that the container and cap not have a child resistant closure apparatus.

Abstract: A liquid dispensing assembly includes a hand-operated trigger sprayer that is removably attached to a bottle container and communicates with the bottle container through a length of conduit.

Abstract: An adjustable nozzle is attachable to the end of a garden hose and is also attachable to a separate product container, for example, a bottle containing a garden fertilizer or a bottle containing a cleaning soap concentrate. The adjustable nozzle receives a flow of water from the garden hose and dispenses a product from the container attached to the nozzle. The nozzle has a simplified construction with a reduced number of component parts and the operation of the nozzle is simplified yet enables a user to selectively discharge a flow of water or a mixture of water and product from the nozzle, to control the ratio of water to product when the nozzle is employed in dispensing the mixture of water and product, and to direct the discharge as a stream or disperse the discharge in an upwardly or downwardly directed fanned spray pattern.

Abstract: A manually operated vertically reciprocated pump dispenser has a simplified construction with two separate pumps that pump two separate liquids from a container and keep the two separate liquids separated from each other as they are pumped through the dispenser, mixing the liquids for the first time in a discharge passage of the dispenser just prior to the mixed liquids being discharged from the dispenser.

Abstract: A telescoping closure is removably attached to a flexible container that can be manually squeezed to dispense contents of the container through the closure when the closure is moved to an opened position. The closure comprises a cap and a dispensing tip that are both mounted for rotation on a container connector that attaches the closure to the container. On rotation of the cap relative to the container connector the dispensing tip rotates with the cap and moves axially relative to the cap to project the dispensing tip axially outwardly from the cap and open an orifice in a distal end of the dispensing tip. With the orifice opened the contents of the container can be dispensed by inverting the container and cap and manually squeezing the container. The cap is rotated in an opposite direction to cause the dispensing tip to move axially back into the cap closing the orifice at the distal end.

Abstract: A trigger sprayer valve assembly that has a conical flange that controls the flow of liquid in a downstream direction through a liquid passage of the trigger sprayer. The valve is constructed with an elongate stem or shaft that facilities the assembly of the valve into the trigger sprayer and a positioning plug that solely holds the valve in a centered position in the liquid passage of the trigger sprayer.
