  • Patent number: 9062777
    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.

  • Patent number: 8864052
    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.

  • Patent number: 8800823
    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.

  • Patent number: 8800822
    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.

  • Publication number: 20140110440
    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.

  • Publication number: 20140061253
    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.
