SELECTIVE AEROSOL VALVE SYSTEM One of the features this invention is to provide an aerosol dispensing valve system for dispensing a first fluid only from its container, a second fluid only from its container or a mixture of the first and second simultaneously from their containers with all dispensing being by way of a dispensing chamber and a dispensing passagein a movable elongated valve stem.
Other features and advantages of the invention will be apparent from the following description of one embodiment thereof taken in conjunction with the accompanying drawings. f the drawings:
FIG. 1 is a side elevational view partially in section of an aerosol container employing a dispensing valve system embodying the invention.
FIG. 2 is an enlarged sectional view partially broken away of the dispensing valve system of the container of FIG. 1.
In H6. 1 there is illustrated a highpressure aerosol unit having a customary cylindrical high pressure container 11 functioning as a first container to retain onits interior 12 a first fluid under pressure. Such a fluid may be a liquid containing a high boiling propellant of which the Freons are good examples.
Positioned within the interior 12 of the first container 11 is a second container 13 which may be an elongated flexible bag of polyethylene or similar plastic material. The top of the first container 11 is defined by a transverse partition 14 which holds a valve 15 shown in enlarged vertical section in FIG. 2.
The valve 15 which 'is thereby located in the package that comprises the first container 11 and second container 13 has an interior dispensing chamber 16 of vertical, generally cylindrical shape. This chamber 16 is provided with a first 17 inlet that connects to a flexible dip tube 18 preferably made of a plastic material such as polyethylene and having an entrance end 19 adjacent the bottom of the interior of the first container 11.
The valve 15 is also provided with a second inlet 20 for the second fluid within the second container 13. This second inlet 211 communicates by way of a flexible dip tube 21 which may also be of a plastic material such as polyethylene with the bottom of the second container of flexible bag 13.
The valve alsoincludes an axially movable elongated valve stem 22 extending vertically through the chamber 16 and having a dispensing passage 23 wit a side entrance 24 commumeeting with the chamber 16 and exit 25 in the projecting nozzle 26 that forms a projecting part of the vertically movable operating cap 27 of the unit 10.
The movable stem 22 is provided with a projection 28, here shown as a collar on the stern beneath the passage entrance 24 and movable with the stem. This projection or collar 28 is provided with a plurality of spaced fluid flow means here shown as vertical passages 29 that communicate at their upper ends with the interior, of the dispensing chamber 16 and at their lower ends with the top of an annular passage 30 between the outer surface of the stem 22 and the inner surface of the tubular second inlet 20 which merged into the second clip tube 21.
At the top of this annular passage 30 there is provided a compressed helical spring 31 whose upper end engages the bottom of the collar 28 and whose lower end engages an annular sealing flange 32 and against which the stem 22 slides in its vertical movement. The helical spring 31 being under compression urges the collar 28 and the attached stem 22 in an upward direction from the position shown in FIG. 2.
The collar 28 is also provided with a seal portion, here shown as an annular tapered peripheral surface 33 that is adapted to block the first inlet 17 when the collar is in the position shown in FIG. 2.
As noted above, the annular inwardly directed flange 32 against which the outer surface of the stem 22 is slidable serves to hold the helical spring 31 in positionfln addition, it
makes sliding sealing contact with the outer surface of the stem 22 and in order to provide fluid flow past the flange 32 in communicating with the annular passage 30 above the flange 32 and its lower end communicating with the annular passage 30 below the flange when the stem 22 is in the position shown in FIG. 2.
Three operating positions of the valve stem 22 are indicated in FIG. 2 by the letters A, B and C. These indicate the positions of the transverse top surface 35' of the collar 28. When the stem 22 has been raised by pressure of the spring 31 to position A, here identified as a first position, the collar is moved away from the first inlet 17 so that fluid that is under pressure in the interior 12 of the first container 11 flows through the dip tube 18 into the chamber 16 for flow outwardly through the dispensing passage 23. This upward movement of the stem 22 to the position A also moves the spanning passage 34 entirely above the annular flange 32'so that this flange blocks exit of second fluid from the flexible bag 13 so that in position A only first fluid is dispensed through the valve system.
When the stem 22 and collar 28 are arranged in the second position indicated at B in FIG. 2 the first inlet 17 is similarly exposed and now the spanning passage 34 spans the flange 32 so that the second fluid can flow from the bag 13 upwardly through the annular passage 30 and into the chamber 16 for mixing with the flowing first fluid from the inlet 17. Thus when the valve parts are at position B a mixture of first and second fluids which is formed in the dispensing chamber 16 flows outwardly through the dispensing passage 23.
When the movable parts of the valve are arranged in the third position shown in FIG. 2, or in the position indicated at C, the seal portion 33 of the collar- 28 effectively seals the first inlet 17 to block flow of the first fluid while the second fluid from the bag 13 flows upwardly in its dip tube 21, through the annular passage 30 by way of the spanning passage 34 and through the vertical passage 29 in the collar 28 into the chamber 16. From this chamber 16 the second fluid only flows outwardly through the dispensing passage 23 in the cap 27, as described.
Thus when the valve stem and collar are in position A of FIG. 2 only the first fluid from the first container 11 is dispensed. When the parts are in position B both fluids flow into the chamber 16 for mixture therein and outwardly through dispensing passage 23. When the parts are in position C only the second fluid is dispensed.
Upon complete release of the cap 27 the spring 31forces the stem 22 and collar 28 outwardly to the extreme position where the top surface 35 of the collar 28 bears against the bottom surface of a flexible seal gasket or sealing member 36 so that this gasket seals the entrance end 24 of the dispensing passage 23, thereby sealing the interior of the aerosol unit 10.
The valve system of this invention therefore permits dispensing either one fluid only, a second fluid only or a mixture the two fluids, as desired.
Having described our invention as related to the embodiment shown in the accompanying drawings, it is our intention that the invention be not limited by any of the details of description, unless otherwise specified.
