Abstract: According to certain embodiments of the invention, a dispensing device may include a pump system having a large, angled spout allowing the downward dispensing of a product into a wash basin or other delivery area. The dispensing device may also include a bottle or container handle having an angle on an interior of the bottle or container such that a dip tube used with the pump system may be forced into a particular portion or location within the bottle or container. The dispensing device may also include a wide, ergonomic actuator which may be actuated by the palm of a hand or a thumb as a user grips a bottle or container to which a pump system is attached and to which the actuator is in communication for actuating the pump system.

Abstract: A tamper evident nozzle shield (100) may be configured to fit a pump or pump dispenser to protect a fluid path (12) in the dispenser from contamination or to prevent or visually indicate if a dispenser or pump dispenser has been tampered with.

Abstract: Pre-compression valve systems for trigger sprayers include one-piece valve systems having both check and pre-compression valves or multiple component valve systems.

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: Pump engines made of recyclable materials and offering a metal free fluid or product flow path include precompression means for applying precompression forces to a fluid being distributed thereby.

Abstract: An aerosol actuator and manifold for dispersing an aerosol product wherein the manifold includes one or more air vents to promote the foaming of an aerosol product dispersed from the aerosol actuator. In some embodiments, the one or more air vents may be positioned downstream of an orifice cup mounted on the orifice of the manifold.

Abstract: A trigger sprayer has a housing, a piston bore within the housing, and a piston reciprocally mounted with 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 unit within the flow passage controls the flow of liquid through the flow passage upon operation of the actuator. The valve unit further comprises a check valve and priming valve. The check valve is shaped in a frusto-conical manner and is assembled into the check valve seat which is not part of the housing but is a separate component. The sprayer has a free spinning threaded type closure for mounting the sprayer to a container, the closure formed separately from and secured to said housing.

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

Abstract: An aerosol actuator which may be connected to a container to form an aerosol delivery system or package wherein the aerosol actuator includes four parts: a base, a trigger, a locking ring, and an orifice cup; the locking ring including a lock stop and the trigger including a locking post to lock and unlock actuation of the aerosol actuator.

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: 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: 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: A trigger sprayer having a valve body configured to accept a discharge valve for a pre-compression configuration or a valve and plug combination for a non-pre-compression configuration where the discharge valve may include a frame and valve which may be bi-injected or assembled to provide a pre-compression valve for the trigger sprayer.

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 one or more of a lip for sealing with a blown-in dip tube, a seal ring configured to mate with a blown-in dip tube and seal therewith, a dip tube lock for mating with a blown-in dip tube, or an o-ring for providing an improved seal with a blown-in dip tube.

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: A sprayer head assembly for dispensing a chemical stored within a container comprises a body having a bore and a valve moveably positioned at least partially within the bore. The sprayer head assembly includes passages for the carrier fluid and the chemical. A vent passage is also provided. The valve selectively closes and opens the carrier fluid, chemical and vent passages. The valve is configured to move in a side to side motion which is generally transverse to a longitudinal axis of the assembly.

Abstract: An actuator for a pump wherein the actuator may be made of a single molded part or multiple molded parts wherein each part or component may define a portion of the spin mechanics of the actuator.
