INVENTOR EDWARD R. YUHAS xw W q ATTORNEYS 1 STRIPED PRODUCT AEROSOL DISPENSER BACKGROUND OF INVENTION This invention relates generally to aerosol dispensing devices, for the co-dispensing of contained separated materials through an actuated dispense system, and more specifically relates to a striped product aerosol dispenser, adapted to provide striped product form codispensing of separately drawn and separately contained materials.
Pursuant to the invention, the striped-product aerosol dispenser provides simplified, safe and efficient co-dispensing, as striped product, of contained materials which are to be drawn separately through the actuator means and co-dispensed only at the point of actual dispensing.
' In accordance with the foregoing, it may be regarded as among the objects of the present invention to provide a novel actuation and dispense system for separate drawing of materials therethrough and for codispensing. the separate materials at the point of dispense as striped product, to be. utilized for dispensing dissimilar materials which would be damaged by intermixing prior to dispense thereof, or for striped toothpaste, or glamour treatment of'other products, or for a similar use.
Now in accordance with the present invention, the I foregoing object and others as will become apparent in the course of the ensuing specification are achieved through use of a striped-product aerosol dispenser operating, as will be described below, so that the materials which are to be co-dispensed as striped product are contained in isolated containers in said aerosol device and are-actuated and drawn through separated channels in said actuator and dispenser by novelsegregated and separated dispensing means to be co-dispensed, at the point of dispensing, in striped product form.
' BRIEF DESCRIPTION OF DRAWINGS v The invention is diagrammatically illustrated, by way ,of example, in the appended drawings,in which:
FIG. 1 is a side sectional elevational view of a striped product aerosol dispenser embodying the invention, in non-actuated position;
' FIG. 2 is a side fragmentary partly broken sectional view thereof, in closed actuated position, showing lines of material flow therethrough; and
FIG. 3 is a front fragmentary view of the striped product aerosol dispenser pursuant to the invention.
DESCRIPTION OF PREFERRED EMBODIMENTS In accordance with the preferred mode of practicing the invention, the striped product aerosol dispenser 11 (FIG. 1), for example, comprises container means 12, actuation means '13, and dispensing member 14. The container means 12, for example (FIG. 1), consists of a first container 20 (for example, a metal container) which contains a material A to be dispensed therefrom, and which has in the embodiment of the invention shown a top rim 21 thereon, and a second container 22 (for example, a collapsible plastic bag having flexible collapsible walls 23) which contains a material B' to be dispensed therefrom, the second container 22 being enclosed within the first container 20 and being sealed therefrom to prevent leakage from one container to the other, and pressurization gas (not indicated) generally occupying the space 24 above the material A in the first container 20 to exert pressure on the material A and on the collapsible walls 23 of second container 22 in order to effectuate pressurized dispensing of materials on actuation of said actuation means 13. I
The actuation means 13 FIGS. 1 and 2), for example, comprises an actuator frame member 30, having a hollow upper portion 31 and a hollow lower portion 32, divided by resilient guard member 33 having a central aperture 34 therein, with resilient member 45 therein, the frame member further comprising a hollow frame tip portion 35 and-frame apertures 36 therein (in the embodiment shown, four. such apertures [a,c, shown, b,d not shown] are located at intervals circumferentially adjacent the top portion of resilient guard member 33), an aerosol actuator member 37 extending through said frametip portion 35, resilient member 45, upper frame portion 31, lower frame portion 32 and resilient guard member 33 for movement therein and therethrough, having a hollow body portion 38, a hollow tip portion 39, a head portion 40, and actuator apertures 41 therein.
Actuation means channels, for separate movement of contained materials therethroug'h are embodied, for example, (FIGS. 1 and 2) in first channel 42, for movement of material A therethrough,.which comprises the hollow in lower frame portion 32, actuator apertures 41, the hollow in body portion 38 and the hollow in tip portion 39, and second channels 43 for movement of material B therethrough, comprising frame apertures 36, the hollow in upper frame portion3l, and actuator channel 44 in the space between the outer surface of actuator tip 39 and the inner surface of frame tip 35.
The dispensing member 14 (FIGS. 1 and 3) comprises, for example, an overcap dispenser member 50 which has bottom rim recess 51 to interfit on depression thereof with top rim 21 of first container 20 to serve as a limit for actuation, thereby-controlling the amount of materials dispensed, bottom tiprecess 52 to receive frame tip portion 35 and actuator tip portion 39 therein, and further embodying channel passages therein comprising first channel 53 for interconnection with said actuator tip portion 39 for drawing material A therethrough, and second channels 54 (in the embodiment shown, four such channels [54a,b,c,d in FIG. 3] are located at 90 intervals circumferentially about said first channel 53) for interconnection with said actuator channel 44 for drawing material B therethrough, and front dispenser surface 55 which is the point of codispense of materials A and B in striped (or other desired effect) product form.
In operation (FIGS. 1 and 2) the striped product aerosol dispenser 11, for example, is actuated by depressing the overcap dispenser member 50, which is in the non-actuated embodiment of FIG. 1, seated atop frame tip portion 35 and tip portion 39 with a space between dispenser bottom rim recess 51 and container top rim 21, to a position in the actuated embodiment of FIG. 2 where dispenser'bottom rim recess 51 is in contact with container top rim 21, depressing therewith actuator hollow body portion 38 which moves in plungertype movement through resilient member 45 and resilient guard member 33 to thereby open first channel 42 and second channel 43 to enable the drawing of materials-A andB therethrough. Material A is pressurized, by pressurizationgas occupying space 24, to flow through first channel 42 in actuation means 13 through the hollow in lower frame portion '32, actuator apertures 41, the hollow in body portion 38 and the hollow in tip portion 39 and through intercommunicating first channel 53 in dispensing member 14; material B is pressurized, by pressurization gas acting on the collapsible walls 23 of the second container 22, to flow through second channels 43 in actuation means 13, through frame apertures 36, (36a, 36c shown, 3.61:, 36d not shown) for example, through the hollow in upper frame'portion 31, and through the-actuator channel 44 space between the outer surface of actuator tip 39 and the inner surface of frame tip 35, and to then flow through intercommunicating second channels 54 (540, 540 shown, 54b, 54d not shown), for example, in dispensing member 14; this procedure thereby draws materials A and vB to the front dispenser surface 55 where the materials are co -dispensed in striped product form.
The striped product aerosol dispenser of my invention operates to draw two segregated separately contained materialsto be co-dispensed, to give a striped fproduct (or other desired) effect. Such striped product couldconstituteany product wherein actual intennixing of the dissimilarmaterials prior tofinal dispensing would be harmful, or to add striped glamour to 'a product, such as toothpaste, for marketing and commercial utilization. Other desired products could be achieved, such as one comprising a marblelized foam, for example, which can be formulated by using materials which are less dense and less'stable to thereby provide an intermittent foam marblelized effect.
While the present invention has been particularly set forth in terms of specific embodiments thereof, it will be evident in view of the instant disclosure, that numerous variations upon the invention are nowenabled to those skilled in them, which variations in propriety are yet within the true scope of this teaching. Accordingly, the invention is to be broadly construed, and limited only by the scope and spirit of the claims now appended hereto.
