Abstract: A venting system of a manually operated trigger sprayer vents the interior of a liquid container connected to the trigger sprayer. The trigger sprayer is provided with a vent chamber that surrounds the pump chamber, and a vent piston that surrounds the pump piston. The vent piston is received in the vent chamber for reciprocating movements between a vent closed and vent opened position in the vent chamber, and the vent chamber having two different interior diameter sections with a larger interior diameter section reducing drag on the vent piston when the vent piston is moved to the vent opened position.

Abstract: A venting system of a manually operated trigger sprayer vents the interior of a liquid container connected to the trigger sprayer. The trigger sprayer is provided with a vent chamber that surrounds the pump chamber, and a vent piston that surrounds the pump piston. The vent piston is received in the vent chamber for reciprocating movements with the pump piston in the pump chamber. The reciprocating movement of the vent piston alternatively opens the vent chamber to the exterior environment of the trigger sprayer and thereby vents the interior of the liquid container connected to the trigger sprayer, and closes the vent chamber thereby sealing the interior of the liquid container from the exterior environment.

Abstract: A closure is removably attachable to a container and comprises a dispensing orifice and a tubular valve element that is biased closed blocking communication of the container with the orifice. By inverting the container so that a liquid contents of the container exerts pressure on the valve element, or by squeezing the container causing the liquid contents to exert pressure on the valve element, the valve element opens communication with the dispensing orifice allowing the liquid contents to be dispensed from the container. On removing the pressure from the valve element, the valve element resiliently closes the dispensing orifice.

Abstract: A closure is removably attachable to a container and comprises a dispensing orifice and a valve element that is biased closed over the orifice. By inverting the container so that a liquid contents of the container exerts pressure on the valve element, or by squeezing the container causing the liquid contents to exert pressure on the valve element, the valve element opens the dispensing orifice allowing the liquid contents to be dispensed from the container. On removing the pressure from the valve element, the valve element resiliently closes the dispensing orifice.

Abstract: A child-resistant trigger sprayer includes a sprayer body having a barrel with an internal passage, and at least one first lug formed integrally with the barrel and extending radially outwardly from the barrel. A nozzle is rotatable on the barrel between at least one first position for dispensing liquid from the passage, and at least one second position for blocking dispensing of liquid from the passage. The nozzle has a flexible resilient skirt that is telescopically received over the barrel and the first lug on the barrel, and at least one pair of second lugs extending radially inwardly from the skirt for circumferential abutment on opposed sides of the first lug to block rotation of the nozzle in both directions from the second position toward the first position. The skirt is deflectable to distort the portion of the skirt carrying the second lugs radially outwardly so as to be rotatable past the first lug.

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 trigger sprayer includes a sprayer body having a barrel with an internal passage, and a nozzle mounted over an open end of the barrel for rotation between dispensing and non-dispensing positions. The nozzle has a plug that is received in the open end of the barrel passage. The plug has laterally opening windows positioned for selective registry with an internal axial slot in the wall of the barrel passage adjacent to the open end of the barrel. The windows in the plug connect with fluid outlets in the nozzle. The nozzle is rotatable around the end of the barrel selectively for bringing the windows into registry with the slot in the barrel to dispense fluid from the end of the nozzle.

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: An indexing nozzle assembly for a trigger sprayer has a manually rotatable cap mounted for rotation on a base of the nozzle assembly. Rotation of the cap relative to the base changes the nozzle assembly between an off condition where the nozzle assembly prevents liquid discharge from the trigger sprayer, and a combination of a spray condition, a stream condition, and/or a foam condition. The indexing nozzle assembly is provided with a child resistant feature in the form of a lock mechanism that prevents rotation of the nozzle cap relative to the nozzle base from the cap off condition position. The lock mechanism can be manually manipulated with one hand to disengage the lock mechanism, thereby permitting rotation of the nozzle cap from its off condition position relative to the base.

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: 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.
