1 Claim. (Cl. ZZZ-402.24)
This invention relates to Small hand-held aerosol dispensers, and more particularly to dispensers of this type which, after assembly of the valve parts, are pressurefilled through a depressible valve stem.
An object of the invention is to provide a novel and improved aerosol dispenser of the kind indicated, wherein a rapid pressure-fill through the valve stem is possible yet upon discharge only a greatly diminished volume of high velocity flow of aerosol substance occurs.
Another object of the invention is to provide an improved aerosol dispenser in accordance with the foregoing, wherein the initial diminished high-velocity flow upon discharge is effected within the valve stem itself, thereby eliminating malfunction which could result from leaky or imperfect fittings disposed beyond the valve stem and operating under high pressures, etc.
A feature of the invention resides in the provision of an improved aerosol dispenser actuator as indicated, whereinthe restricting of the discharge flow within the valve stem is effected by a plug part of the stem actuator or depress button.
Another feature of the invention resides in the provision of'an improved aerosol actuator as above characterized, wherein the actuator button has a small-area, high-velocity discharge channel cooperating with the plug part of the button, to provide the desired overall flow and velocity characteristic of the dispenser.
Other features of the invention reside in the simplicity, compactness, small size and low fabricating cost of the flow-controlling actuator provided by the invention.
Still other features and advantages will hereinafter appear.
In the drawings accompanying this specification, similar character of reference are used to designate like components throughout the several views, in which:
:FIG. 1 is an axial sectional view of an aerosol dispensin'g device actuator as provided by the invention, mounted on a dispensing container, only the upper portion of the latter being illustrated'and being shown mainly in side elevation.
FIG. 2 is a top plan view of the actuator button of FIG. 1. t
FIG. 3 is a bottom plan View of the actuator button of FIGS. 1 and 2.
FIG. 4 is a front elevational view of the actuator button of the preceding figures, and
FIG. 5 is a rear elevational view of the actuator button.
As shown, in FIG. 1, an actuator cap designated generally by the numeral is mounted on a pressurized aerosol container 12, the latter having an annular shoulder 14 which is gripped by the lower rim portion 16 of a cylindrical, stationary cap body 18.
The pressurized container 12 has a usual type of valve assemblage (not shown in detail) carried in a central inverted cup-like portion 20 of a top closure member 22.
Extending upward from the valve assemblage in the portion 20 is a hollow depressible valve stem 24 of usual construction. Components as thus far described are also illustrated and described in Patents Nos. 3,179,310; 3,161,330; 3,160,182; and 3,153,497.
It is a usual practice, in pressure-filling containers like the container 12, to apply a filling nozzle to the valve stem 24 (with the actuator assemblage 10 not in place) and to inject the pressurized aerosol substance through the passage or bore of the valve stem. Under fairly high pressures, a satisfactory relatively quick filling of the container '12 may be effected by thus passing the substance through the bore of the stem 24. While the bore is of relatively small diameter, it is large as compared with the diameter of orifice pieces such as the piece 25 carried by the actuator 10 and which produce the fine spray or mist comprising a low volume, relatively high velocity of the aerosol substance.
For general all around use, the restriction of the discharge passage represented by the small opening 40 of the orifice piece 25 is satisfactory. However, under certain conditions it is desired that a restriction of the flow be had ahead of the orifice piece or the location where the orifice piece is usually located, on the actuator button. As another example, if instead of the orifice piece 25 an extension hose is secured to the actuator button for the discharge of aerosol substance, it may be desirable to effect a restriction of the flow ahead of the extension hose. Other conditions might also warrant such restriction of the flow, reducing the volume of aerosol substance while maintaining an effective high velocity of flow where appreciable pressures exist in the container and where the aerosol substance is of very low viscosity.
In accordance with the present invention an improved and particularly simple and inexpensive means is provided by which a restriction of the flow of aerosol substance is effected essentially Within the valve actuator stem 24 itself, thereby acting on one of the salient parts of the valve assemblage, i.e. the hollow discharge ,valve stem, and also eliminating may joints or pieces beyond the stem which might malfunction (in the discharge passage system of the depress button or actuator) upon being subjected to high pressures.
As seen in FIG. 1, the actuator assemblage 10 comprises also a vertically movable depress button 26 which is carried in the cylindrical body 18 and guided thereby, said button having a central hollow depending boss 28 which frictionally fits over the upper end of the valve stem 24 and makes a pressure-tight fit therewith. By the invention, the depress button 26 also has as part of it a flow-restricting plug 30 disposed within the depending boss 28 and adapted to be received within the bore of the top portion of the valve stem 24 and also to frictionally fit therein and make a substantially pressure-tight connection thereto.
The flow-restricting plug 30 has a vertical groove 32 in its one side, said groove being of relatively small cross sectional area as compared with the bore of the valve stem 24. The depress button 26 also has a lateral discharge passage 34 which communicates with the side groove 32 of the plug 30 and with the bore of the hollow boss 28.
Further, in accordance with the invention, an addi tional flow-restricting and controlling plug 36 is provided in the lateral passage 34 of the button, said plug 36 having a horizontally extending groove 38 along its bottom surface. The groove 38 in the plug 36 communicates with the discharge passage 34 and thus with the bore of the boss 28 and the side groove 32 of the plug 30.
The depress button 26 has a sloping finger-engageable top face 42 as shown, together with a cylindrical side wall 44 which bears in the body 18 and is guided thereby, the latter having a vertically extended slot 46 to clear the discharge member or orifice piece 25 of the button. It will be noted that the orifice piece 25 is inserted in the passage 34 of the depress button 26 with a friction fit, and that the inner end of the orifice piece 25 terminates at an appreciable distance from the inner end of the passage 34, so as to provide a distribution chamber 34a between said inner ends.
It will be understood that with the parts in the positions shown in FIG, 1 no discharge of the aerosol substance occurs because the valve stem 24 is in its raised, closed position. However, when the button 26 is depressed or forced downward, it will shift the valve stem 24 downward to the open position, whereupon aerosol substance will pass upward through the bore of the valve stem, upward through the limiting side groove 32 of the plug 30, and thence horizontally through the groove 38 of the plug 36 and through the discharge orifice 40 in the orifice piece 25. Since the valve stem 24 is spring-urged upward, removal of operating force from the depress button 26 will result in the latter returning to its raised, non-discharging position.
It will now be understood that we have provided a novel and advantageous, particularly simple and low-cost means which is disposed within the depressible valve stem 24, for restricting the flow of aerosol substance to a small volume at relatively high velocities, by virtue of the provision of the slotted or grooved plug 30, and also have provided an extension of such restricted passage in the horizontal plug 36 having the groove 38. Moreover, the provision of the horizontal plug 36 in conjunction with the transverse discharge passage 34 of the button still enables a flexible discharge hose or other discharge member such as the orifice piece 25 to be securely, quickly attached to the actuator button by a connection which is leakage-free and not apt to malfunction.
The actuator assemblage is seen to be simple, small and compact, and capable of being molded of plastic substance, at low cost. The simplicity and interfitting nature of the connections make for trouble-free use of the dispenser.
Variations and modifications may be made within the scope of the claim, and portions of the improvement may be used without others.
