mesne assignments, to Knapp-Monarch Company, St. Louis, Mo., a corporation of Delaware Application September 18, 1946, Serial No. 697,805
3 Claims.
This invention relates to a spraying device in which a container of liquid is charged with gas from a sealed bulb or the `like and thereafter the gas within the containma acts on the liquid to displace it through a harge opening whenever a valve for the opening is moved to open position. The device is particularly adapted to serve as an aerosol bomb.
One object of the invention is to provide a liquid spraying device having a valve of novel construction that eliminates the usual valve seat and valve plug, petcock or other type of valve usually provided for controlling the flow of liquid under pressure.
Another object is to provide an aerosol bomb which is readily reiillable and rechargeable with gas pressure for dispensing the liquid contents.
Still another object is to provide an assembly of container, dischargevalve, bulb holder and piercing unit in which the bulb holder serves conveniently as a handle for the aerosol bomb.
A. Vfurther object is to provide a valve structure in which a capillary tube extends from the discharge nozzle into ailuid delivery passageway and has a packing surrounding it, the inner end of the tube being sealed and the tube being provided with. an opening that is normally exterior of the packing but may be adjusted to a position interior thereof for permitting fluid ilow, the tube being returnable by spring pressure and the valve being thereby openable by thumb pressure in opposition to the spring pressure.
With these and other objects in View, my invention consists in the construction, arrangement and combination of the various parts of my device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, wherein:
Figure l is a vertical sectional view through an aerosol bomb embodying invention and showing the device approximately full size.
Figure 2 is an enlarged sectional view of the valve structure of the bomb showing the Valve in open position as distinguished from the closed position of Figure 1; and
Figure 3 is a further enlarged sectional view on the line 3 3 of Figure 2 showing details of construction of the valve.
On th accompanying drawing, I have used the reference character iii to indicate a container adaptable to contain liquid i2 under high pressure. The container iii has a bottom it and in its upper end a threaded boss iii is soldered or brazed..
A body member with a suitabie g :et it interposed between the two to prevent leakage. lihe body B has a nozzle 23 screwed into it for projecting laterally there- B is screwed into the boss i6 dil" from. The body is provided with a threaded nipple 22 projectieor .in the opposite direction.
A bulb holder 24 is adapted to be screwed onto he nipple 22 and contains a bulb 2t of CO2 gas, air or the like under high pressure. The bulb 26 has a puncturable cap 2S adapted to be propelled toward a piercing pin Si) in a well-known manner by means of screwing the bulb holder 2d into position.
The piercing pin 3B is hollow so as to receive gas from the bulb and such gas passes through the threads of a plug 32 to a passageway 34 leading into the boss I6 and the container I0.
where it acts on the liquid I2 to displace the same as will hereinafter appear.
gas from the` bulb being applied suddenly to the container lil.
Surrounding the neck of the bulb and spaced from the piercing pin 3i! is a rubber sealing sleeve 345 which seals the neck of the bulb relative to the body B as soon as the bulb is associated with the body member and before its cap is pierced.
A syphon tube 3i! is screwed into the bottom of the body member B and terminates in a bellshaped reception iitting 40 at its lower end. The
tting lli) is located in a sump 42 of the container bottom Iii. f
The upper end of the syphon tube 38 communicates with a bore 4t in the body member B in which is slidably mounted the lower end of a capillary tube 46. The bore 44 is only slightly larger in diameter than the diameter of the capillary tube.
Above the bore lll is a packing washer 48 held in position by a, packing gland 5U. The tube 46 is slidable through the elements 43 and 5d and has an opening 52 normally located above the packing washer as shown in Figure l.
The tube l5 after extending upwardly bends laterally and enters the nozzle 29, being confined in a bore 5d thereof. The bend of the tube passes through the bottom of a cup member 56 and f through the side of a valve depresser 58. The' cupi and depresser are normally held in the raised position of Figure 1 by a spring or restoring means im.
ber B and a stop projection 68 engaging a cupshaped retainer lt. The retainer 'l0 is: held in position by the nozzle 2U.
l The capillary tube 4S is closed at its lower end as indicated at 'l2 and together with its opening 52 the packing wash-er 48 and the bore 4d constitutes a valve that prevents iiuid iiow when the parts are in the position of Figure l. thumb button 62 is depressed it will, through the valve depresser 58, bend the tube 4t inwardly of The threads of the` plug 32 permit but very slow flow of the gas.Y This arrangement prevents the possibility of the.
They are limited in the upward di-v rection by a thumb button (i2 having a projec-I i tion te pivoted in a socket 65 of the body mem-` When the? 3 its anchored discharge end in the bore 54 of the nozzle 29 and move the tube so that its opening 52 is below the ,packing washer 48 Vinstead of above it. This is the position'shown in Figure 2. The valve is now open and the liquid l2 under pressure can flow upwardly in the syphon tube 38 and the bore 44 and then through the opening- 52 into the capillary tube idrnally discharging in the form of a very fine atomizedspray `.indicated at 14 in Figure 2. After the desired rquantity of liquid has been dispensed Jthe thumb VVbutton 82 can be released whereupon the Aspring 89 will propel the parts back to the initial position of Figure 1. This arrangement provides a 'very simple valve structure which will give long life and ftrouble frfee foperation.
It will Vlbe notedithjat the boss I8 extends vdownwardly :into the 'container 'lil which precludesnlling thelcontainerabove the level `of liquid shown in Figure 1. This leaves the necessary space for the introduction of gas under'pressure from the bulb 26. V
The external 'diameter of the capillary tube 46 is but slightly smaller .than the internal diameter ofthe bore #le fasshown in AFigure 3. In a valve of T.the size shown in Figure v1 Tfor instance the outer diameterotthe tube may be approximately .028" and the internal diameter of the .bore about :0116" Vto .908" larger. This Vwill give a space all laround the capillary tube fthat is .003 to .1004 wide. This results in -a maximum area in fthe space between the tube and the bore of approximately .0008" which is only two twentyfifths of one percent of one square inch. This isthearea over which the pressure in'the'syphon tube ilxis exerted against the packing washerd. Being small, 'the `force (pressure area) will vproduce only approximately .l2 lb. persq. in. pressureon the packing when the container is chargedvvithfgas at 150`p0undsgpervsquare inch. The :pressureon the Apacking lis according-ly substantially megligible Vas distinguished rfrom the pressures involved vin :most types of valves.
From the foregoing specification it will be obvious `that I have Aprovided a simple type of reiillable insecticide dispenser or vaerosol bomb whichcan-be conveniently charged with the require'dpressure'for discharging liquid in aerosol formV by association of a compressed gas bulb with the bomb. It will be noted that the bulb holder is AinV such-position with relation to the container and to the thumb button 82 'that it serves conveniently as a 'handle rfor supporting the :device and the thumb button can be readily depressed by the .thumb of the hand holding the bomb.
The valve acts as a positive seal when closed and the 'bomb `can :therefore be used intermittently with long periods of non-use yetis always ready to use whenneeded. When the bomb is emptied of liquid, this fact is ydenoted by the/discharge of gas instead of liquid when the -valve is open. Relling is readily accomplished by unserewing the body member B from the container Il) `and 'after lling, the bomb :is readily recharged cwith pressure from a bulb. These operations require a minimum of time.
Some changes may be made in the-construction anda-rrangement of the :partsof my device withoutpdeparting from vthe Vreal spirit .and 4purpose of my invention,.andlit is my intention to cover byimyclaims any-modiiied forms of structure or use of mechanical equivalents which .may Vbe reasonably included within .their scope.
"valve structure mounted in said body member for pontrolling the discharge of liquid from said container, said valve structure including a discharge nozzle mounted rigidly on said body member, a push button `operable by the thumb of the hand holding said body member, and a tube having a portion recip-rocated thereby and another portion extending laterally to said discharge nozzle and bending during the valve opening and closing operations, said first portion having a closed end insaid passage, packing around said portion, said portion havinga lateral opening adapted -to lrbe selectively located either inwardly or .outwardly of said packing.
