Abstract: The present invention relates to a chemical sprayer that includes a sprayer head assembly and a container. The container defines a cavity for storing a chemical to be sprayed. The sprayer head assembly includes a chemical passage, a carrier fluid passage, a vent passage, a valve chamber and a valve. The chemical passage is communication with the cavity. The carrier fluid passage is in communication with a carrier fluid source. Both the carrier fluid and chemical passages are in communication with the valve chamber. The valve is moveably positioned within the valve chamber and defines at least partially a first passage and a second passage. The first passage is configured so as to be in communication with the chemical passage when the valve is in an open position. The second passage is configured so as to be in communication with the carrier fluid passage when the valve is in the open position.

Abstract: Aerosol spray devices (100) may include one or more actuators (130) located on the sides or on the rear of the device wherein actuation of the one or more actuators disperses product from a container in communication with the spray device. A selector mechanism (150) may be used to toggle between an “on” and an “off” position for the one or more actuators.

Abstract: An improved manifold for an aerosol system may include a valve interface (120) capable of flexing to fit with a valve stem of an aerosol system and form a seal and methods for making a manifold may include a gate (106) positioned to improve contact between steel defining a fluid flow path in the manifold.

Abstract: Pump engines and pump assemblies include a metal free fluid or product flow path and a precompression feature integrated into a piston incorporated in the pump engine.

Abstract: A snap fitment system for attaching a closure such as a valve body to a container may include one or more fingers attached to the valve body and held in a securing position about the container by a retaining ring.

Abstract: A simplified pump system may include a bellow having a suction valve, a stem, and a fluid lock wherein the product flow into and out of a pump chamber formed by the bellow and stem is controlled by the suction valve and fluid lock.

Abstract: A pump and container connector fitment system (210) for retaining a pump (200) on a container (120) and allowing the pump to be removed through rotational forces from the container.

Abstract: An aerosol trigger actuator having two or three parts includes one or more living hinges (170) allowing the two or three parts to act together to release a product from a container.

Abstract: An aerosol actuator including a director capable of extending an outlet of the aerosol actuator away from the aerosol actuator and which may be configured to include a multi-function nozzle for selecting a dispersing pattern.

Abstract: A trigger sprayer has a housing, a piston bore within the housing, and a piston reciprocally mounted within the piston bore. The housing further includes a flow passage through which liquid passes from a passage inlet to a passage outlet. An actuator is operable to reciprocate the piston within the piston bore between a vacuum stroke creating reduced pressure in the piston bore and a compression stroke creating increased pressure in the piston bore. A valve assembly within the flow passage controls the flow of liquid through the flow passage upon operation of the actuator. The valve assembly further comprises a check valve and a priming valve. The sprayer has a closure for mounting the sprayer to a container. The valve seat for the check valve is in a component formed separately from and operatively connected to the housing.

Abstract: A pump system may include a blown-in dip tube connected to a valve body and having a connection which may include an improved blown-in dip tube connector having a swivel adaptor, or a rotatable connector, which creates a fluid path from a blown-in dip tube of a bottle to a trigger sprayer. The swivel adaptor, or rotatable connector, may also include a body or head which may be attached to a valve body, tube retainer, or valve retainer of a trigger sprayer.

Abstract: A valve system for a trigger sprayer including a valve forming an air spring with a portion of the trigger sprayer and being made of a flexible or elastomeric material. The trigger sprayer may include an air-spring valve system wherein the air-spring valve system provides precompression during a pump stroke. The precompression forces developed in the valve system during a pump stroke may originate from an air valve or air pocket trapped between a portion of a valve body and a part of the valve system. For example, a valve may be inserted in a tube retainer which is connected to a valve body of a trigger sprayer. Air trapped in a chamber or space between a portion of the valve and the tube retainer may provide a force against the valve such that a certain force must be applied to the valve before it allows product to be released.

Abstract: According to certain embodiments of the invention, a valve guide or raised boss may be connected to or integral with a base or body of an aerosol actuator. In various embodiments, a valve guide may include a raised boss associated with a grip or body of an aerosol actuator. The valve guide or raised boss may align a manifold with a valve when an aerosol actuator is assembled to a container containing a product. In addition, a valve guide or raised boss may limit the movement of a portion of a manifold in a defined direction or defined plane such that the load on a valve by a manifold is controlled. For example, a valve guide may ensure a top load on a valve during actuation or may minimize side loads on a valve during actuation.

Abstract: A trigger sprayer may include a rotatable nozzle to facilitate the discharge of liquid from the nozzle in any desired direction and may also include a locking mechanism for preventing activation of the trigger sprayer. The trigger sprayer may also fit within the footprint of a container to which the trigger sprayer is attached.

Abstract: Fluid dispensing devices having a pump system connected to a container wherein the dispensing device may be operated with one hand using either a container having a griping surface or opening or a handle integrated with an actuator to facilitate one-handed use.
