An aerosol actuator which may be connected to a container to form an aerosol delivery systems or package wherein the aerosol includes two parts: a base and a trigger, the trigger including an integrated cap for the base, trigger, spring or living hinge, manifold and orifice.

A spray cap system is described that can enable a user to more consistently and accurately dispense and work with the contents of a spray can. The system includes a spray cap, spray button, spray nozzle, implement holder, and an implement (such as a brush, a foam pad applicator, or a sponge). By using the spray cap system, a user may achieve a more optimal discharge pattern of the contents of the can with a more efficient and optimal coverage of a surface. In addition, the user may utilize the implement while it is attached to the spray cap or remove the implement to use the implement independently. The spray cap system provides versatility to a user by enabling the user to spray the contents of the spray can regardless of whether the implement is attached to the spray cap.

An actuator for operatively engaging and dispensing a fluent medicament from a package in the form of a spray. The actuator includes a housing to receive and hold the package and further includes a force amplification mechanism that is connected to, and movable with respect to, the housing. The housing further includes a force transfer mechanism operatively engaged with a portion of the package. The force amplification mechanism is coupled with force transfer mechanism for accumulating a force sufficient to dispense the medicament from the package in the form of a spray.

A valve for a fluid dispensing container includes a mounting cup to be fixed on a container, a housing to be fixed on the mounting cup and defining a channel with an inlet end and an outlet end, whereby a hollow stem is glidingly arranged in the channel. The stem is flange-free and a concentric circumferential conical sealing protrusion on the stem forms the sealing between the outer surface of the stem and the housing. When the stem passes from the open into the closed position, it enters at least partially into the housing without product being retained between the flange of the stem and the housing.

A fluid dispensing cap has a trigger vertically operable to actuate a valve. The cap has a window located below the trigger. The window defines a side edge and a bottom edge of the cap. A plate has a tab projecting therefrom. The plate also has a bottom surface with a channel. The plate is disposed in the window. A linking rib connects the plate to the side edge of the cap. The bottom edge is disposed in the channel. Movement of the trigger to actuate the valve is prevented until the plate and tab are affirmatively removed.

A dispensing device for a fluid dispenser has a housing, a dispensing mechanism and a dispensing nozzle which can be displaced parallel to a longitudinal extension of the dispensing device by means of the dispensing mechanism. A fluid container is connectable to the dispensing device of the fluid dispenser for the passage of fluid through the dispensing nozzle. The dispensing mechanism has an actuating handle which can be actuated substantially transversely to the longitudinal extension. The actuating handle comprises two actuating elements which are arranged opposite to one another in relation to the dispensing nozzle, wherein at least one actuating arm is assigned to each actuating element, the actuating arm extending on the inside of the actuating handle between the actuating element and an actuating surface of the dispensing nozzle, the actuating surface being formed perpendicularly to the longitudinal extension of the dispensing nozzle.

A dispenser system for a pressurized canister including an actuator including components such as an external housing, a valve having a top stem connector for attachment to an output hose, support pins, and a one way ball check valve having a stem fitting with an extended valve stem for engaging the pressurized canister, a pivoting actuator control or trigger, having a trigger return spring, to bias the trigger out of engagement with the valve, unless a stop pin is removed and the trigger is pivoted into operating engagement under compression of the trigger and trigger return spring by a user. The sensor may communicate with a mobile device to indicate when to stop dispensing contents from the canister.

An aerosol sprayer may be connected to an aerosol container to form an aerosol delivery system. The aerosol sprayer includes a base secured to the container, a cap secured to the base, a pivoting trigger and a nozzle which is slidably movable relative to the trigger between an extended operable position and a retracted, locked position. The nozzle and trigger have interfitting locking structures to prevent actuation of the trigger when the nozzle is in the retracted locked position.

A spray dispenser includes a container, a valve body, a valve stem, a supply channel, an actuator, and a nozzle. The container valve stem, supply channel and nozzle are in fluid communication. The valve stem is movable from a closed position to a fully open position, wherein in the closed position the valve stem channel is not in fluid communication with the interior of the container, wherein in the fully open position the valve stem channel is in fluid communication with the interior of the container. The actuator is in operative communication with the valve stem, wherein the actuator is movable from resting position to a fully actuated position, wherein in the resting position the valve stem is in the closed position, and wherein in the fully actuated position the valve stem is in the fully open position. The nozzle includes a swirl chamber adjacent the end face and having a chamber depth CH extending along the nozzle longitudinal axis NL and a chamber diameter CD, and wherein the swirl chamber is disposed generally concentric with the cavity and in fluid communication with the grooves, wherein chamber diameter CD is less than or equal to 800 microns and the chamber depth CH is less than or equal to 500 microns.

A spray dispenser includes a container, a valve body, a valve stem, a supply channel, an actuator, and a nozzle. The container valve stem, supply channel and nozzle are in fluid communication. The valve stem is movable from a closed position to a fully open position, wherein in the closed position the valve stem channel is not in fluid communication with the interior of the container, wherein in the fully open position the valve stem channel is in fluid communication with the interior of the container. The actuator is in operative communication with the valve stem, wherein the actuator is movable from resting position to a fully actuated position, wherein in the resting position the valve stem is in the closed position, and wherein in the fully actuated position the valve stem is in the fully open position. The supply channel defines a supply channel length L.sub.SC measured along a central axis fluid flow through the supply channel, wherein the supply channel length L.sub.SC is greater than 23 mm. A minimum Dv90 particle size exiting the discharge orifice when the valve stem is fully open defines a fully open minimum Dv90 particle size, and wherein a maximum Dv90 particle size exiting the discharge orifice when the valve stem is fully open defines a fully open maximum Dv90 particle size, wherein a fully open Dv90 particle size range is the difference between the fully open maximum Dv90 particle size and the fully open minimum Dv90 particle size, wherein the fully open Dv90 particle size range may be less than 10 microns.
