Abstract: An actuator comprising an actuator skirt defining a recess sized to receive a portion of a pedestal of a mounting cap. The actuator having a passageway providing communicating between a valve stem and an insert received within an insert cavity of the actuator. The insert has a discharge orifice and a locking member while the insert cavity has a mating locking member. The mating locking members engage with one another to retain the insert within the insert cavity and allow adjustment of a spray discharge pattern of the insert. The insert cavity has a cavity hub which engages with a leading end of the insert, in an over lapped manner, to form a fluid tight seal therewith and minimize leakage therebetween. An angle rib is attached to a lower surface of the actuator body and abuts against the pedestal, prior to full depression of the actuator, to tilt the actuator slightly upward so that the discharge product does not impinge against the aerosol container.

Abstract: A metering valve assembly comprising a ferrule and a valve housing defining an internal cavity. The valve housing accommodates an annular flange and a compression spring therein with a valve gasket closing the internal cavity. The valve housing is attached to the ferrule such that a stem portion of the valve stem protrudes through apertures provided in both the valve gasket and the ferrule. A stem portion has a discharge passageway which is normally closed by the valve gasket. Either an undersurface of the annular flange or a mating surface of the valve housing is provided with a compressible sealing member while the other is provided with an annular edge. The compressible sealing member and the annular edge form a seal therebetween, when the valve stem is sufficiently depressed, to partition the interior cavity into a metering chamber and a separate filling chamber whereby product may only be dispensed solely from the metering chamber when a product flow path is established.

The container to be pressurized includes a base, a side wall, and a dome having a perimeter bead, with the perimeter bead of the dome defining an opening having transverse cross-sectional area which is less than a transverse cross-sectional area defined by the side wall of the container to be pressurized. The method comprising the steps of forming the barrier pack with a transverse dimension which is less than a transverse dimension of the opening of the dome. Inserting the barrier pack, with the transverse dimension less than the transverse dimension of the opening of the dome, through the opening of the dome, without application of force, so that the barrier pack is accommodated within an internal compartment of the container to be pressurized with a flange of the barrier pack supported by an annular bead of the dome.

Abstract: A valve assembly having both a primary low/fine product dispensing flow rate and a secondary high/coarse product dispensing flow rate. The primary low/fine product dispensing flow rate is achieved upon initial vertical depression of the valve stem while the high/coarse product dispensing rate is achieved upon maximum vertical depression of the valve stem. An internal compressible member is located within the valve assembly to provide a detectable indication, to an operator of the valve assembly, that further depression of the valve stem will increase the product flow dispensing rate from the primary low/fine dispensing rate to the secondary high/coarse dispensing rate.

Abstract: An actuator for facilitating filling of an aerosol contain by a button-on-filling process, the actuator comprising an exterior housing having an outer wall with a product discharge outlet formed therein. The exterior housing further having central post supporting an internal bore which establishes fluid communication between a product inlet and the product discharge outlet to facilitate dispensing an aerosol product via the actuator. At least two spaced apart reinforcement ribs are provided for interconnecting the exterior housing with the central post and thereby define at least two compartments where any remaining filling component may collect. A base of the exterior housing has an annular skirt portion which facilitates sealing engagement with a pedestal portion of a mounting cup during a filling operation.

Abstract: An actuator assembly for an aerosol container provided with a stem. The actuator assembly controls the dispensing of an aerosol product from the container. The actuator assembly includes a base which supports an actuator within a throughbore of the base in a cantilevered fashion. The actuator is provided with a primary discharge orifice for discharging the product from the aerosol container in a first spray configuration. The actuator assembly includes a secondary actuator mechanism which, when in an inactive position, allows the primary discharge orifice to control solely the discharge of the product to be dispensed from the aerosol container. The secondary actuator mechanism, when in a second active position, communicates with the primary discharge orifice and controls the spray configuration of the product to be dispensed as it is dispensed from the aerosol container. The secondary actuator mechanism can either be pivotally attached to the actuator assembly or completely removable therefrom.

Abstract: A spray actuator which has an inlet which communicates with a discharge orifice outlet via a passageway and a discharge cavity. The discharge cavity accommodates a central post therein which supports a plurality of axial fins that may be each provided with stop shoulder. An insert member, carrying a discharge orifice, is received within the discharge cavity and engages with the support fins and the stop shoulders. The insert member is provided with an annular lip which has an interference fit with the inner side wall, defining the discharge cavity, to retain permanently the insert member within the discharge cavity. An end face of the side wall of the insert member abuts against the stop shoulders to prevent overinsertion of the insert member into the discharge cavity and thereby prevent inadvertent deformation or crushing of the mechanical break-up. An end face of the central post has a mechanical break-up molded therein which impart a tangential spin to pressurized product as the product flow therethrough.

Abstract: In an aerosol valve which includes a flow path with a compartment having an inlet into the compartment and a valve seat at the upper end of the compartment, a pocket is disposed downward from the seat opening, the pocket contains a gravity-responsive ball. When the valve is being used during dispensing and is tipped in a direction which brings the ball closer to the flow through the compartment, the ball becomes entrained in the fluid flow and flies up to seat on the valve seat to block it off, precluding further discharge. When the aerosol valve is further depressed, the ball will be forced away from the seat to again open the discharge path. The purpose of the valve is to avoid the escape of propellant or product which might occur in tipping if the lower end of the dip tube is exposed to the head space.

Abstract: An aerosol valve has a body with a circular side wall extending down beyond the floor of the body to define a socket. Into this socket is frictionally engaged a symmetrical appendage having a circular upper end and a tailpiece at its lower end. The body is vertically partitioned into a primary product passage communicating from the tailpiece upward through an opening in the floor of the main valve. On the other side of the partition the lower end of the chamber is provided with a valve seat with an opening communicating with the primary passage. A side opening is formed through the appendage above the valve seat, and a ball is adapted to seat on the valve seat when the container is in normal position. When the container is inverted, the ball drops away from the seat and permits passage of product through the side opening, through the valve seat opening into the primary passage and up into the valve for discharge.

Abstract: In an aerosol valve the flow path includes a compartment having an inlet into the compartment and a valve seat at the upper end of the compartment, a pocket is disposed downward from the seat opening, the pocket containing a gravity-responsive ball. When the valve is being used in dispensing and is tipped in a direction which brings the ball closer to the flow through the compartment, the ball becomes entrained in the fluid flow and flies up to seat on the valve seat to block it off, precluding further discharge. When the aerosol valve is released, a bypass raises the pressure inside the valve body so that the ball will fall away from the seat. The purpose is to avoid the escape of propellant which might occur in tipping if the lower end of the dip tube is exposed to the head space.
