Definitions

  • the present invention relates to actuators for aerosol valves and in particular to an actuator comprising an extended tubular member and a multiple orifice distributor head.
  • Hair care products have been in the retail and professional markets for many decades and now include a wide assortment of products that appeal to consumers of all ages, gender and demographics.
  • hair styling has evolved far beyond the traditional "hair spray,” (i.e., aerosol hair setting spray), and now include products for shine, spiking, conditioning, cleaning, scenting, and coloring hair.
  • Many of these products are available in a variety of physical forms such as gels, foaming mousses, pomades, creams, liquids, and aerosol sprays.
  • Aerosol sprays include unique products such as dry shampoos that are sprayed into the hair, allowed to dry, and then brushed out.
  • Early versions of dry shampoos appeared decades ago and were rice starch dry-powder aerosols.
  • Some hair care products need to be applied only to the outer portions of the hair shafts (such as color streaking), whereas some hair care products such as conditioners and cleaners need to reach all portions of the hair, including the portions of the hair closest the scalp.
  • some hair care products such as conditioners and cleaners need to reach all portions of the hair, including the portions of the hair closest the scalp.
  • application of hair care products close to the scalp is very problematic since it is difficult to tease the hair apart and to reach in through thick hair to the portions of the hair shafts closest to the scalp.
  • packages and dispensers for hair care products tend to either focus application of hair care products too narrowly or tend to spray product too broadly into the air with little actually in the hair.
  • Most problematic are the traditional aerosols that seem to put more hair care product, (e.g. setting sprays or dry shampoos), into the air and on only the outer surfaces of fuller hair.
  • Multiple orifice actuator buttons are a simple and intuitive way to direct an aerosol effluent into a particular spray distribution pattern.
  • Such multiple orifice actuators have been described in the art, both for hair care products and for unrelated technologies such as paint. Some of these inventions are useful for distributing hair care products into human hair and/or pet hair.
  • US Patent No. 7,278,590 discloses a multiple orifice actuator where the pathway of the aerosol effluent (in this case a wall-texturing material) may be selected by the user for a particular application.
  • US Patent No. 6,877,924 (Mears, et al.
  • US Patent No. 5,772,077 discloses a unique attachment to an aerosol package that includes a combination of a hair styling implement and a valve actuator.
  • the Tafur invention does not necessarily extend the outlet point of the aerosol effluent but it does provide a method for teasing the hair apart while simultaneously spraying hair care product.
  • US Patent No. 5,765,601 discloses an extension to an aerosol can for an aerosol tire inflator.
  • US Patent No. 5,307,964 discloses a general purpose actuator extender for use on domestic and industrial aerosol spray cans.
  • the extension includes a flexible, elongated tubular member that provides accurate/targeted delivery of the aerosol effluent.
  • the Toth invention should find particular use in the insecticide and lubricant industry since the fine tube extension inevitably provides "pin-point" delivery of aerosolized product.
  • Another general purpose extension for use on an aerosol can is described in US Patent No. 3,784,063 by Otis, et al.
  • the Otis invention includes a bent tubular extender that may be rotated around to infinite positions in order to deliver the aerosol effluent in any direction.
  • EP0244293 discloses an extension for use on an aerosol hair mousse product.
  • the Goncalves invention provides a plastic extension that is easily operated by finger depression to deliver foaming mousse at the outlet tip of the long, tapered extension.
  • dry shampoo formulations include the herbal dry shampoo composition disclosed in US Patent No. 5,872,087 (Neelakantan ), and a chitin based composition disclosed in US Patent No. 4,035,267 (Gleckler, et al. ). Powder aerosols in general have been described by Gunning, et al. in US 3,081,223 and Shinozawa in US 4,450,151 . Any of these compositions, if aerosolized into a conventional aerosol package with a simple button actuator, will be difficult to deliver to the portions of the hair near the scalp.
  • an exemplary embodiment of the present invention is an actuator mountable on an aerosol valve that provides not only a physical extension of the outlet of the aerosol valve but also a distribution system for directing the aerosolized effluent through a multiple channel/orifice structure.
  • the actuator functions as an applicator for aerosolized products.
  • the actuator of the present invention may be mounted atop a depression-actuated valve (vertical valve) or a tilt-valve, and may be equipped on an up/down aerosol valve configured to operate either upright or inverted.
  • the actuator may be mounted on an up/down aerosol valve of an aerosol package where the composition within the aerosol package is a dry shampoo.
  • the present actuator comprising a long tubular member terminating in a distributor head minimizes the "fly away" seen when a dry shampoo is dispensed from a conventional aerosol package having only a standard actuator button.
  • the actuator comprises a mechanical break-up actuator (MBU) with the incorporation of at least one mechanical break-up insert positioned in the fluid stream at any position between the aerosol valve exit and the exit orifices on the distributor head.
  • MBU mechanical break-up actuator
  • the actuator comprises a non-mechanical break-up actuator (NMBU).
  • NMBU non-mechanical break-up actuator
  • the distributor head of the present actuator comprises laterally directed orifices that enable distribution of aerosolized hair care products at right angles to the scalp.
  • FIGURE 1 is a perspective view of one embodiment of the present actuator attached to an aerosol can.
  • FIGURE 2 is a cross-sectional view of another embodiment of the present actuator attached to a depression-actuated/vertical valve, where the elongated tubular member of the actuator terminates in a 4-orifice distribution head.
  • the actuator of the present invention may be non-mechanical break-up (NMBU) or mechanical break-up (MBU) in overall configuration, the configuration chosen with regard to the physical form of the aerosol product to be dispensed (e.g.
  • the present actuator may dispense pressurized product in any direction depending on the location of the exit orifices around the distributor head, (e.g. vertical or lateral, or any other angled direction).
  • the preferred material of construction of the present actuator is plastic, other materials may be envisioned for constructing the actuator.
  • the present invention may be constructed from a single piece of fabrication material (e.g. a single injection molded plastic part) with contiguous portions or it may comprise an assembly of separately manufactured elements (of same or different materials of fabrication) that are snug or snap-fit, glued, or sonically welded together to form the completed actuator.
  • the actuator of the present invention may be used on top of any aerosol valve, be it a tilt-valve or a vertical valve.
  • the present actuator may be situated on an aerosol valve assembly that is equipped with a conventional dip tube that reaches to the bottom of the aerosol can, or on an "up/down" valve that operates from any orientation of the can.
  • the configuration of the aerosol package is beyond the scope of the present invention, but include such configurations as (1) an aerosolized can where propellant is mixed with product in single phase or multiple phase compositions, or (2) bag-in-can, or (3) bag-on-valve systems where the propellant is physically separate from the dispensing product.
  • the actuator of the present invention minimally comprises an elongated tubular member having a first, or proximal, end configured dimensionally to fit sealingly to an aerosol valve (either a male proximal end of the actuator fitting into a female valve, or a female proximal end of the actuator fitting onto a valve stem of a male aerosol valve) and a second, or distal, end that terminates and merges in a distributor head comprising a system of internal channels and two or more exit orifices.
  • the actuator optionally comprises at least one mechanical break-up insert positioned within the aerosol effluent flow.
  • an exemplary embodiment of the actuator 1 of the present invention comprises an elongated tubular shaped portion 8 and a multiple orifice distributor head 9 integral with the elongated portion.
  • the exemplary embodiment illustrated includes seven (7) distributing orifices 10 located on the head portion 9.
  • An upper limit of exit orifices may be the point where there is no practical way to fabricate the head portion 9 of the actuator.
  • the preferred number of orifices is between 2 and 10, with 2 to about 5 orifices being more preferred.
  • the preferred distributor head may be of a bulbous shape as in the illustrated embodiment, similar to a home shower head or the end of a plant watering can.
  • the exit orifices 10 may be configured on the top surface of the distributor head (as in the illustrated embodiment), resulting in a nearly vertical dispensation of the aerosol effluent (aerosol effluent distributing in a coaxial direction with respect to the direction of the axis of the elongated tubular member), or they may be arranged circumferentially around the side of the distribution head 9 such that the aerosolized effluent is expelled nearly lateral in relation to the long axis of the vertical tubular member 8.
  • the exit orifices 10 function to distribute the pressurized aerosol stream that originates from the aerosol can 2 into multiple directions within the hair of the user.
  • the exit orifices 10 are configured on the side of the distributor head such that the aerosolized product may be expelled laterally from the tubular member 8 in order to reach hair shafts adjacent to the scalp without concomitant soaking of the scalp itself.
  • the aerosolized product stream may be propelled under pressure with a propellant that is mixed with the formulation in the aerosol can 2.
  • propellant(s) plus liquid and/or powder hair care ingredients may be single phase or multiple phases depending on the ingredients and propellant(s).
  • the composition to be dispensed under pressure may be inside a bag within the can and the propellant(s) injected between the can and bag, usually through a port provided in the bottom of the can.
  • the stream of product may bifurcate into two equal outputs.
  • a central/axial bore within the elongated portion 8 (not shown in FIG. 1 ) allows the aerosol effluent to travel in fluidic communication from the aerosol container 2 out to the exit orifices 10.
  • the actuator 1 of the present invention may be comprised of a single molded plastic piece, or may be an assemblage of two or more subcomponents each having various functions.
  • the distributor head 9 may be a piece that is separately molded and then press-fit, glued or screw-threaded to the elongated tubular portion 8 of the actuator, reversibly or irreversibly as needed.
  • the actuator of the present invention may be a mechanical break-up actuator by the presence of a mechanical break-up insert positioned in the effluent stream.
  • the distributor head 9 may be separated from the elongated portion 8 of the actuator by an intervening mechanical break-up (MBU) insert that helps to create turbulence and mechanically break-up the aerosol stream originating from the aerosol can before the aerosol is propelled through the distributor head and out the orifices 10.
  • MBU mechanical break-up
  • such an intervening mechanical break-up insert may be placed further up-stream in the actuator of the present invention, such as close to, or even at the exit to the aerosol valve.
  • a three piece actuator comprising an elongated tubular portion, a mechanical break-up insert, and the distributor head. All of these pieces may be configured to fit together such that the aerosol effluent travels from its exit from the aerosol valve, through the axial bore within the tubular member, through any optional MBU inserts, to eventually exit from the orifices 10 an onto the hair of the user.
  • Mechanical break-up inserts used in conjunction with aerosol actuators are amply disclosed in the literature, including in U.S.
  • Any of these MBU inserts may be incorporated within the actuator of the present invention depending on the composition of the product to be dispensed and the desired particle size of the effluent.
  • These references discuss the preferred diameters of the inlet passages to the MBU insert, the size and configurations for the swirl chambers to create the desired turbulence and particle break-up, and the sizes of the exit orifices. These diameters may be incorporated as the preferred diameters of the various passageways, channels, swirl chambers, and exit orifices of the present actuator.
  • the distributor head 9 may also comprise its own separate insert(s) (MBU or NMBU) when there are several orifices 10 desired at the distributor head 9.
  • MBU separate insert
  • NMBU NMBU
  • actuators with multiple exit orifices are more easily constructed with a separately molded insert that is pressed into the body of the actuator, and the Gehres method may be the more preferred way to construct the distributor head portion 9 of the present actuator because of the preferred multiple numbers of channels and orifices in the head 9.
  • inserts would be preferred for the construction of a distributor system that can change the direction of the effluent originating in a axial/vertical direction through the tubular member 8 to a lateral direction out the exit orifices 10 (i.e. configuring appropriate channels within the distributor head 9 that function to turn the effluent direction at right angles from elongated direction of the tubular member 8).
  • the actuator 1 of the present invention may be constructed in part or in whole of materials other than plastic.
  • a metal distributor head 9 may be attached to a plastic elongated tubular portion 8, giving rise to mixed materials of construction for the present actuator.
  • the tubular portion 8 may be a long metal tube and both the mechanical break-up insert and the distributor head (and its separate insert(s)) may comprise plastic injection molded parts that are fit to the tubular member.
  • the present actuator comprises a movable actuating button 7 further comprised of one or more additional structural elements as needed for operation of the aerosol valve.
  • the actuating button 7 preferably comprises a finger-sized platform (i.e. relatively flat surface) configured on a top/horizontal surface or configured on a side/vertical of the button structure that the user may depress or pull laterally with a finger or thumb, in order to operate the aerosol valve and dispense aerosolized product.
  • depression on a ribbed platform configured on the horizontal top surface of the actuating button 7 depresses a vertical aerosol valve beneath the actuator with subsequent distribution of the aerosolized product through the distributor head 9 and out the orifices 10.
  • the moveable actuating button 7 may be comprised of a wedge-shaped or other three-dimensionally shaped structure depending on a number of considerations such as: (1) the nature of the aerosol valve, e.g. vertical actuated or tilt actuated; (2) what material(s) the actuator is made from; and, (3) ornamental design effects.
  • the actuating button 7 may comprise a three-dimensional wedge shape (like a slice of pie), and may be molded plastic and hollow. This three-dimensional wedge shape may be positioned offset to only one side of the elongated tubular member 8.
  • the actuating button 7 may be smaller in size than the embodiment illustrated in FIG.
  • the actuating button 7 may comprise any other practicable shape besides a three-dimensional wedge so long as an approximately finger-sized platform is provided on a vertical face or on the uppermost horizontal top of the button such that the thumb or the finger of the operate may interact with the button 7 to depress it axially or leverage it radially.
  • the present actuator 1 preferably includes a movable plate, 6 incorporated as an integral element of the actuating button 7 (essentially a base to the button) to hide the recessed valve cup beneath, and it may be molded contiguously with both the actuating button 7 and elongated tubular member 8 of the actuator.
  • the plate 6, button 7 and tubular member 8 are collectively a single molded piece of plastic, and the tubular member 8 is at the center of the plate 6.
  • the plate 6 is of a substantially disc-shape, with an axis and radius, and the elongated tubular member 8 and the plate 6 together form a wheel and axle arrangement, wherein the tubular member 8 extends axially out from the center axis of the disc-shaped plate 6, and a right angle is formed between the flat surface of the plate 6 and the tube 8.
  • This arrangement is preferred because the tubular member 8 needs to be coupled onto the aerosol valve and the valve is necessarily at the center axis of the aerosol can.
  • the plate 6 may also take the shape of the footprint of the actuating button 7, and does not necessarily need to be disc-shaped. Where the plate 6 is not disc-shaped, the tubular member 8 may extend off from the plate 6 from a position close to a "center point" of the plate, such that the actuator 1 will fit onto the aerosol valve.
  • a cap structure comprising a horizontally disposed ring 5 and circumferential skirt 3 may also be part of the present actuator, and this cap structure is also usable to hide the recessed valve cup present at the top of a steel aerosol can.
  • Aerosol cans typically have a mounting cup as part of the aerosol valve assembly, and that mounting cup is peripherally crimped to the open top of the aerosol can to create an annular bead.
  • the cap structure comprising ring 5 and skirt 3 elements may be dimensioned in diameter and form to appropriately snap over the annular bead of an aerosol package and to assist with alignment of the tubular member 8 into a female valve or onto the valve stem of a male valve assembly present on the aerosol package.
  • the skirt 3 may include an inwardly extending annular lip adapted to engage under the annular bead of a crimped aerosol can.
  • the top edge of the circumferential skirt 3 is attached integrally to and around the outer circumference of the horizontal ring 5, as expected for the horizontal top and vertical skirt elements that form a cap or closure.
  • the ring 5 has a circular outer circumference, as is necessary to conform to the annular bead of the aerosol can, and it has an aperture therethrough. If the ring 5 is shaped like a flat washer, then the aperture therethrough is outlined by a circular circumference herein referred to as the inner circumference of the ring 5.
  • the aperture through the ring 5 need not be disc-shaped, and as mentioned above it may be in the shape of the footprint of the actuating button 7.
  • the ring 5 is most preferably in the shape of a flat washer and will necessarily have both an outer circumference/diameter and an inner circumference/diameter.
  • the relatively flat plate 6 is molded in hinging relationship with a portion of ring 5, for example through a weakened area often referred to as a "living hinge.” That connection point between the ring 5 and the plate 6 may be from about 2° to about 180° around the outline of the aperture of the ring 5.
  • the cap structure of the present actuator configured to snap fit over the annular bead of an aerosol can, may be seen as having a horizontal top with a cut-out that defines an aperture in which the plate 6 resides and pivots by hinging at a connection with the ring 5.
  • the plate 6 may take the shape of the footprint of the actuating button 7, such that other shapes that are not necessarily perfectly disc-shaped are anticipated for the plate 6.
  • the shape of the flat plate 6 takes the shape of the aperture in the ring 5, such that the plate 6 and the aperture of the ring 5 are complementary shapes (i.e. the plate 6 preferably takes the shape of what was cut out from the cap structure to form the aperture).
  • the actuating button 7 is preferably molded on top of the plate 6, pressing down on, or leveraging against, the actuating button 7 concomitantly pivots the plate 6 within the aperture of the ring 5. Similar structural elements are disclosed by Pierre-Andre Lasserre in US Patent No. 6,202,899 , incorporated in its entirety herein by reference.
  • the actuator is preferably dimensioned to fit securely over the circular valve cup crimped to the top of the can and to fit sealingly to the valve exit.
  • the internal fit of the aerosol valve stem from a male aerosol valve assembly up into the first/proximal end of the elongated tubular member 8 of the actuator should be snug enough such that no product can leak at this connection when the aerosol valve is actuated. Therefore, the inner diameter of the proximal end of the tubular member 8 must be configured to accept in sealing arrangement the male valve stem of a male valve assembly.
  • the actuator may comprise a proximal male end to the tubular member 8 that fits into a female aerosol valve.
  • the aerosol can 2 may be of any size and construction and its features are not within the scope of the present invention.
  • the can 2 may be extruded aluminum or steel, and it may be slim and tall or otherwise fat and stout.
  • the aerosol package will comprise some sort of crimped structure at the top, and a valve assembly will include a typical aerosol valve, such as a vertical depression-actuated valve or a tilt-valve and the valve assembly will be crimped to the open end of the can.
  • the present invention is intended to fit onto the valve of the aerosol package and to coordinate with the operation of the aerosol valve through depression or leverage of the actuating button 7.
  • the present actuator should fit sealingly onto the valve stem of a male valve or into a female valve and may be operable with downward pressure on the platform of the actuating button to actuate the aerosol valve, or the actuating button of the present actuator may be leveraged laterally (by pulling against a vertical wall of the button structure) in order to cooperate with a tilt-valve supplied on the aerosol package.
  • FIG. 2 a cross-sectional view of another preferred embodiment of the actuator 1 of the present invention is illustrated wherein the actuator 1 is coupled to an aerosol can 2 and is snugly fit onto the male valve stem 17 of the male valve assembly 13.
  • the aerosol valve 13 is a vertical valve having a spring that biases the valve in the closed position until the valve stem 17 is vertically depressed.
  • the actuator 1 preferably comprises an extended tubular member 8 that further includes a central/axial bore 15 through it lengthwise.
  • this member necessarily comprises a relatively narrow diameter compared to its axial length, and the axial length is hollow by definition.
  • the tubular portion 8 has a first end proximal to the aerosol package that is configured with appropriate internal diameter to fit sealingly to the male valve stem of an aerosol valve. A sealing arrangement means that aerosolized product will not leak at this connection point.
  • a second/distal end of the elongated tubular member 8 i.e. the end furthest away from the aerosol can ends and merges into the distributor head portion 9 mentioned above.
  • the actuator of the present invention may be configured with a "male" end at the first end of the tubular member 8 such that the first end of the tubular member 8 of the present actuator will fit through the female valve cup and the cup gasket and fit onto the stem seat.
  • the button actuator includes a slotted male stem that will fit down into the female valve assembly of the spray paint can.
  • the proximal end of the tubular member 8 may comprise such a slotted male configuration in order to dimensionally fit within a female valve assembly.
  • the exemplary embodiment illustrated in FIG. 2 comprises four (4) outlet orifices 10 that distribute the aerosol effluent evenly into quarter (1/4) volumetric portions.
  • the top view FIG. 2a depicts the preferred evenly spaced, radial arrangement of the four orifices 10 on the substantially round distributor head 9 when the exit orifices 10 are configured on the top of the bulbous shaped distributor head 9.
  • the exit orifices 10 may be positioned circumferentially around the side of the distributor head 9 such that the exiting aerosolized product is directed lateral to the scalp, (i.e. approximately at right angles to the length of the elongated member 8).
  • such an insert will comprise a swirl chamber to help create turbulence to break up the product into smaller droplets.
  • the effluent may be mechanically broken up with an MBU insert positioned just where the internal channels 4 of the distributor head branch from the axial bore 15.
  • the internal channels 4 may be branched off from a single exit orifice of an MBU swirl chamber where the distal end of the central bore 15 acts as the inlet to the swirl chamber.
  • the aerosol effluent may be mechanically broken up with the aid of separate MBU inserts that are fit into each of the outlet orifices 10.
  • each exit orifice 10 on the distributor head 9 may have an MBU insert, resulting in a total of four separate MBU's with swirl chambers, and where the orifices 10 are the outlet orifices from each of the MBU swirl chambers.
  • the distributor head 9 is comprised of internal channels 4 and outlet orifices 10 that together function to distribute the aerosolized effluent both volumetrically and directionally.
  • One or more optional MBU inserts may be positioned anywhere in the fluid flow, for example as close as directly adjacent to the valve assembly or as far downstream as just before the exit orifices 10.
  • Optional MBU insert(s) are used to convert an otherwise non-mechanical break-up actuator into a mechanical break-up actuator in instances where the effluent will emerge as a stream and where smaller spray particles are desired.
  • the operation of the exemplary embodiment of the actuator illustrated in FIG. 2 comprises the steps of pressing down on the upper ribbed platform 7a of the actuating button 7 which effectively pushes the entire actuator 1 down, simultaneously depressing the valve stem 17 to operate the vertical-action valve 13.
  • No leverage is required for this arrangement since the vertical valve 13 is operable by a straight downward depression of the valve stem that forces the spring of the aerosol valve out from its biased-closed position.
  • Plate 6 may flex or otherwise hinge on the ring 5 as necessary when pressure is applied to surface 7a by the operator since the plate 6 is preferably in a hinging relationship to ring 5.
  • the axial bore 15 through the length of the tubular member 8 must extend through the plate 6 such that the tubular member 8 may be coupled to the male valve stem of a male aerosol valve.
  • the tubular member 8 must also extend through the plate 6 if the tubular member is configured to fit within the valve seat of a female valve assembly.
  • plate 6, ring 5, and skirt 3 together form a cap structure dimensioned to snap snugly over the crimped annular bead 12 formed between the valve cup 11 and the aerosol can 2, effectively closing off the view of the valve cup 11.
  • plate 6 is in effect the cut-out portion from the horizontal top of a cap, and plate 6 moves within the cut-out in the cap, that cut-out now defined by the dimension of the aperture through ring 5.
  • the length of the elongated portion 8 of the present invention is widely variable. It may be as short as 1 inch, or may be as long as 12 inches.
  • the length of the elongated portion 8 of the present actuator may be from about 1 inch to about 6 inches.
  • the actuator may be included with the aerosolized hair care product as a separate part, perhaps taped or otherwise temporarily banded to the side of the aerosol can 2, or included within a secondary carton along with the can 2, where it is expected that the consumer will attach the actuator 1 to the aerosol can 2. This embodiment eliminates the worry that insufficient shelf clearance in the store may not accommodate the length of tubular member 8 and the fully assembled aerosol package may be too tall to be practicably merchandised.
  • the diameter of the elongated tubular portion 8 is entirely variable, although the preferred width/diameter should be just thick enough such that the elongated stem 8 won't easily snap off when run in between thick hair.
  • the outside diameter of the elongated tubular member 8 may be from about 1/16 to about 1/2 inch.
  • the tube 8 have a circular cross section to simplify adapting the first end as a female opening to fit a circular male valve stem or as a slotted male end to fit within a female valve assembly.
  • the axial bore 15 is most preferably circular in cross-section, and the bore may be initially molded within the elongated member 8, or coaxially drilled therethrough as part of a later manufacturing step.
  • the actuator 1 of the present invention may be used in conjunction with a tilt-valve rather than a depression-actuated (vertical) valve.
  • Tilt-valves are amply described in the prior art, including U.S. Patent No. 3,658,294 (Ewald ) and U.S. Patent No. 5,957,342 (Gallien ), both of which are incorporated herein in their entireties.
  • the actuator 1 may actuate the aerosol valve by a lateral pressure placed against a vertically disposed platform 7b rather than by downward pressure on a horizontally disposed platform 7a.
  • the elongated tubular member 8 functions as a tool for teasing apart thick hair while working the distributor head 9 in closer toward the scalp of the user.
  • the spray emanating from the distributor head will necessarily be close to the scalp, and hair care or personal care product will be evenly distributed across many hair shafts without undesired "fly away” and concomitant wasting of product.
  • the exit orifices on the distributor head may allow for right-angled spray of product from the scalp, or for vertical application of hair care or other personal care product directly onto the scalp, depending whether the orifices are configured on the top or along the sides of the distributor head.
  • Products that may find more effective application by way of the present invention include, but are not limited to, perfumes, scalp conditioners, anti-dandruff treatments, hair spiking compositions, hair setting compositions, hair coloring products, hair shine products, hair conditioners, and hair cleansers.
  • Dry shampoos are hair cleansing products that are sprayed into the hair, allowed to dry, and then brushed out, with no water required in the hair cleaning operation.
  • the ingredients for example rice starch, absorb hair oils and other soil and such soils are then brushed out along with the dried starch residue.
  • These products are convenient for cleansing the hair on the go when no shower or other means is available to wash the hair in the traditional fashion.
  • the biggest problem with dry shampoo aerosols is that they cannot be easily applied to the entire length of the hair, particular if the consumer has thick and/or long hair. The "fly away" from such products is enormous, and most of the aerosolized product ends up in the air.
  • the present invention offers the user a way to distribute a dry shampoo aerosol into a full head of hair, getting the cleansing product in close to the scalp and across all the hair shafts.
  • Right angle application of dry shampoo lateral to the scalp is possible by orifices positioned on the sides of the distribution head. The user may tease apart the hair with the elongated tubular member, reach to the scalp with the distribution head of the actuator, and then distribute the dry shampoo aerosol at right angles to the scalp.
  • Touching the top of the distributor head onto the scalp is an indication to the user that operation of the actuator will give good distribution of dry shampoo to the hair shafts close to the scalp. Once the user feels the distributor head touching the scalp, actuation of the aerosol package will cause dry shampoo to distribute at right angles to the scalp, but very close to the scalp.
  • a dry-powder aerosol may be dispensed through the actuator of the present invention.
  • the valve assembly used on the aerosol package may be an improved valve that is custom configured for use with dry-powder aerosols.
  • Aerosol valves that are specifically configured for dispensing dry-powder aerosols have been described in US Patent Nos. 6,394,321 (Bayer ); 5,975,378 (Bayer ); and, 3,586,216 (Jordan ), each of which are incorporated herein in their entireties.
  • the most useful adaptation of the present actuator for use with an aerosolized dry shampoo product is with an aerosol package that may be used in the inverted position.
  • the distributor head of the actuator may be detachable and interchanged with other distributor heads by the manufacturer or even by the end user consumer.
  • two or more distributor heads may be supplied and the consumer is given the option to interchange these distributor heads to meet his/her particular needs.
  • the consumer may be given heads that have different numbers of exit orifices, or orifices that are positioned to dispense aerosol in different directions. That is, the optional distributor heads may provide for different spray patterns.
  • One distributor head supplied to a consumer may be attached by the consumer to the distal end of the elongated tubular member to create an MBU actuator, whereas a second distributor head supplied to the consumer may be attached by the consumer to the distal end of the elongated member to create a NMBU actuator.
  • two or more fully complete actuators of the present invention may be supplied to the consumer.
  • One non-limiting example would be to supply different length actuators to the consumer with a single aerosol product.
  • the consumer may choose which of the included actuators to use, and then snap the chosen actuator onto the aerosol package depending on fullness of the consumer's hair.
  • the elongated tubular member of the present actuator functions as a tool to tease apart the hair while simultaneous working the distributor head of the actuator closer to the scalp, allowing application of hair care formulation to hair close to the scalp or directly to the scalp.
  • the distributor head of the present actuator allows for wider distribution and lateral distribution of product close to the scalp without undesired and wasteful product "fly away.”
  • Various configurations of the elongated tubular member and the distributor head allow for construction of overall MBU and NMBU actuators, and choice in the direction of aerosolized effluent.
  • a preferred use for the actuator of the present invention is in conjunction with an aerosol package comprising an up/down valve that may be operated in either the upright or the inverted position, (e.g. by provision of alternative entry points into the aerosol valve using slide/ball valves for bypassing the inlet of the dip tube), and in particular where the aerosol hair-care formulation is a dry shampoo product for cleansing the hair without water rinsing.
