  • Patent number: 10589920
    Abstract: A system releases spray fluid in different mass flow rates. The system includes an actuator having a first area and a second area, a stem connected to the actuator and having a first orifice and a second orifice, a gasket covering the first orifice and the second orifice in a non-actuated position, and a biased member biasing the stem to the non-actuated position. When the first area of the actuator is pressed, the stem moves a first distance relative to the gasket to uncover the second orifice and compressing the biased member to spray fluid with a first mass flow rate. When the second area of the actuator is pressed, the stem moves a second distance relative to the gasket to uncover the first orifice and the second orifice to spray fluid with a second mass flow rate greater than the first mass flow rate.

  • Patent number: 10399766
    Abstract: 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.

  • Publication number: 20180022537
    Abstract: An aerosol valve with a refill prevention mechanism is provided. The valve has a valve stem disposed in a valve housing that defines an inner chamber. The valve stem has upper passage in an upper portion of the valve stem that is provided with a flexible resilient member. The flexible resilient member is compressed on an orifice or aperture communicating with the housing to create a seal and prevent filling in an open position when pressure in the upper passage is greater than a pressure in the inner chamber. The flexible resilient member is deflected away from the orifice or the aperture when pressure in the upper passage is less than a pressure in the inner chamber to allow dispensing of a product.

  • Patent number: 9260237
    Abstract: A cap for a container that stores and dispenses fluids or gels that includes a shroud having a shroud wall surrounding an opening and a collar connected on the shroud so that the collar selectively rotates relative to the shroud, is provided. The collar is rotatable between a closed position and an open position. The actuator is connected to the shroud, and has a contact portion. The contact portion is in the opening of the shroud. The actuator is movable in the closed position and the open position by a force that is applied to the contact portion only after removal of a tab.

  • Publication number: 20140034745
    Abstract: A vortex spray generating system that comprises a discharge channel and at least one inlet channel. The discharge channel and the at least one inlet channel are disposed with respect to one another such that the at least one inlet channel is capable of providing a tangential feed of fluid into the discharge channel sufficient to generate a vortex and spray pattern. A method of generating a vortex in a pressurized fluid so as to deliver the pressurized fluid as a spray. The method comprises providing a vortex spray generating apparatus comprising a discharge channel and at least one inlet channel, and introducing a tangential feed of fluid through the at least one inlet channel into the discharge channel sufficient to generate a vortex and spray pattern. The at least one inlet channel is disposed such that it is perpendicular to the discharge channel or angled with respect to the discharge channel.

  • Patent number: 8286830
    Abstract: An aerosol valve actuator with a top portion rotatable on a bottom portion. The entire top portion in one rotatable position is depressible vertically to actuate the valve. A click post and clicking rib provide a single click in each direction of rotation. Flanges on top and bottom portions interact to stop rotation as soon as each click occurs. Plastic springs interact with spring biasing members only when the top portion is in actuating position, and assure return of the actuator top portion to full upward position for rotation after actuation of even a short-stemmed valve. Downwardly extending flexible connecting flanges connect the actuator top and bottom portions. The top portion has a lower periphery with a plurality of upwardly extending indentations to overlie lateral ribs in the lower portion in actuation position. The top and bottom portions have interfitting cylinders to stabilize the top portion and maintain verticality.

  • Patent number: 8118197
    Abstract: Metal discs, preferably circular, are cut to a precise diameter and drawn to a preform with a channel and skirt for an aerosol valve mounting cup. The preform then undergoes further forming operations at stations in a press system. “Bumping” is carried out on the skirt edge at a station, to eliminate non-burr trimming of the cup edge, save material and obtain a carefully controlled skirt height and a substantially even skirt edge with minimized earring. The resultant cup terminating skirt edge is characterized by reformed metal. A further coaxing or pinch-cut operation may be performed on the cup skirt.

  • Patent number: 8002000
    Abstract: A bag-on-valve aerosol valve system in a container is provided. Propellant is pressure filled around the valve stem, outwardly over the stem gasket and down into the container space outside the bag. Product is filled through the valve stem into the bag. The valve stem has an exterior intermediate frusto-conical annular surface and the valve housing has an interior frusto-conical annular surface, with both surfaces engaging in annular sealing contact to block propellant access to the bag when the valve stem is deeply depressed to a first predetermined position for propellant pressure filling. A stem exterior surface indent interacts with radially-biased spring-loaded slides to lock the stem in a second less depressed predetermined position for product filling through the stem down into the bag.

  • Patent number: 7582242
    Abstract: An aerosol valve actuator with a valve stem engaging portion, product dispensing opening, and flexible and expandable product conduit between the engaging portion and dispensing opening. The product conduit is molded at least in part of a first expandable flexible plastic material softer than a second plastic material of the remainder of the actuator. The remainder of the actuator is first molded, followed by molding the first plastic material to form at least a part of the product conduit. After the actuator has been actuated to dispense a foaming product and actuation ceases, the post-foaming product expands within the product conduit since the conduit expands to absorb the product expansion. Actuator cap and base product dispensing side openings align only during valve actuation. Base inwardly flexible members and cap internal ramps bias the cap upwardly when actuation ceases. Base upper portion telescopes in base lower portion during actuation.

  • Patent number: 7530476
    Abstract: A locking aerosol dispenser with a dome, a top thermoplastic elastomeric button member molded over a dome opening, and a base lock member. The rotatable base lock rotates from locked to unlocked position with respect to the essentially non-rotatable dome. A product channel member in the dome is held by the elastomeric button, and not otherwise attached to the dome. The base lock has an upstanding bridge with unlocking slots within which extend fingers on the product channel member when the dispenser is unlocked and actuated. The base lock is not attached to the aerosol valve mounting cup. The dome is attached to the base lock member and the aerosol valve mounting cup, the dome capturing the base lock member between the dome and aerosol container.

  • Publication number: 20090014679
    Abstract: A plastic aerosol valve with a plastic valve stem, plastic housing, plastic mounting cup, and plastic locking ring. The plastic valve is assembled into the mounting cup. The plastic housing is assembled into the plastic mounting cup by snap fittings. The plastic mounting cup has a peripheral portion that snap fits up into the plastic locking ring. The plastic locking ring has frangibly-connected upper and lower portions. The lower portion snap fits with the top of a plastic product bottle to mount the aerosol valve assembly on the bottle. The upper ring portion thereafter is telescoped downwardly over the lower ring portion to lock and retain the aerosol valve assembly on the pressurized bottle. The plastic mounting cup can be molded separately, or integrally with the plastic locking ring. A check valve may be contained in the valve stem.
