Ware
a corporation of' Dela- Apnlicatien September 18, 19.46, Seria-1 Ncftili 3 Claims.. (o1. esi- 78) My present invention relates to an aerosol bomb or similar type of spraying device 'in which a container of liquid is charged with gas from a CO2 bulb or the like and thereafterl the gas displaces the liquid through a discharge opening whenever a valve for the 'opening lis" moved to open position. i
One object of the invention is to provide a valve of this general character :which eliminates the usual valve seat and valve plug, Vpetcoclr or other type of valve usually provided'forcontrolling the now of liquid under pressure.
Another object is to provide anaerosol bomb which is readily renewable as to liquid' contents, and as to gas pressure for dispensing the'liquid contents.
Still another' object is to provide an assembly of container, discharge valve, and bulbholder and piercing unit, in whioh'the bulb holder serves conveniently as a handle for the aerosolbomb.
With these and other objects in' view, my invention consists in the construction, arrangement and combination of the various partsof def vice whereby the objects contemplated `arejattained, as hereinafter "more fully set ifntli,l pointed out in my claims and illustrated the accompanying drawinga'wherein:
Figure l is a verticalsectional'view through an aerosol bomb embodying my invention.v
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 l, and
Figure 3 is a more greatly enlarged sectional View on the line 3-3 of Figure2 showing .details of the valve.
On the accompanying drawing I have used the reference character I to lindicate a container, which container is provided with a bottom member I 2 and, is adapted to contain liquid i4 such as insecticide or the like. The container Hl has a threaded boss I 6 into which a head H is screwed with a gasket I8 interposed between the head and the upper end of the boss.
The head has a boss 20 on which a bulb holder 22 is threaded for containing a bulb 24 of CO2 gas or air under highcompression. and for `propelling the bulb toward a hollow. .piercing pin 26 in a well known manner.` The piercinglLp/in 26 is carried by a flanged fitting 28 located in a bore 30 of the head H and this bore is connected by a passageway 32 to the interior of the boss I6. A capillary tube 34 extends from the tting 28 through the passageway 32 for discharging gas into the boss I6 and into the container I0. A
Sealing sleeve 36 of rubber 0r, the likgis e911-` iaiaedinaii enlarged part of the here 319i@ Seal against the ntfkef` th bulb ,24` during the pier@- iasoperatioa asrphori tube 38.112,5 its upper @nel `saure@ in the ,head H and terminates .iii a bell Shaped@- ception fitting, 40a@ its lower, en@ The ttins 40 is loatd, in. a .Sums *4.2, @f thecontaiaer bettom I 2,. A capillary tube-"44 ef slightly less diameter than theinternal diameter` o fv .the Syphcn ,tube 38 is `SlidablymQunted 'in tb-ausw end of the syphun tubeand .isalso .Slidable through a plug 46 screwed into the head H to Compress a gasket .48surr0und1ns the. capillary tube.
The upper end of the capillary tube passes through a `slidablepplug 50Vand coniignedbe-L tween it and a slidablepushvbutton element 52.`
The elementsv 50. and `i2 z l wardly against a flanged closure,nlug541` by a spring 56 as shown in Figure V1 and maybe depressed as in Figure 2 .by thumbpressurecn the push buttonelement 52.
The capillary tube 44 has a right angle bend at its upper end that 'provides a discharge nozzle 58. The head H has a vertical slot 6U in which the discharge nozzle 58 may move from theupper position of'` Figure 1 tothe lower position of Figure.2 whereiniitr"` centeredrelativetoa de-`- pression `(i2 inthe front of l theV head The Capillary tube `44 has an opening `Silfirl one side thereof and its flower endis closed as indicated at 66.` lInithe :upperposition of Figure l, the opening 64 ,isvabove the packing 48 vthus preventing iluidrlovv` from the'discharge nozzle 58. In the position of `Figure 2 the lopening 64 is below the packing `Il!! thus 'permitting uidlow underwthe pressure of. the'gas vintroduced from the bulbl24 into the container l0. This arrange ment 'provides a verysimple valve and one which will give long life and trouble-free operation It will be noted that theboss' I6 basa downs wardly extending endil whichprecludes lling the container l0 above thelevel of liquid shown inFigure 1-` l e sary space for introduction of gas: under pressure from the .bulb24. The capillarytube 34 :throttles the iiowoi gas so that `itisnt discharged too violently intothe containerrlll after the ,bulb is pierced.
The slot 6U' in cooperation with the depression 62 in the front of the head H protects the relatively small nozzle 58 from damage when the aerosol bomb is not in use. At that time the nozzle 58 is in the upper part of the slot as shown in are, normally; held lip- ',Ihis is in,v order-'to ,leave the neces-V- Figure 1 and by dot and dash lines in Figure 2. The upper part of the slot is wider than the length of the projecting part of the nozzle to give the protection desired.
When the nozzle is lowered to the full line position of Figure 2 the nozzle projects from the surface of the depression 62 so that the portion of the head surrounding the nozzle does not interfere with the atomizing action produced by discharge of liquid under high pressure from a minute opening as represented by the internal diameter of the capillary tube 44.
The external diameter of the capillary tube 44 is but slightly smaller than the internal diameter of the syphon tube 38 as shown in Figure 3. In a valve of the size shown in Figure 1, for instance, the outer diameter of the capillary tube 44 may be approximately .028 and the internal diameter of the tube I8 about .006" to .008l larger. This will give a space all around the capillary tube that is .003 to .004 wide. This results in a maximum area in the space between the two tubes of approximately .0008 which is only two twentyfifths of one percent of one square inch and this is the area that the pressure in the syphon tube 38 exerts against the packing 48. This area being very small will produce only approximately .12 lbs. per sq. in. pressure on the packing when the container Il] is charged with gas at 150y pounds per square inch. The pressure on the packing is accordingly substantially negligent.
From the foregoing specification it will be obvious that I have provided a simple type of refillable aerosol bomb which can be conveniently charged with the required pressure for discharge of liquid in aerosol form by association of a compressed gas bulb with the bomb. It will be noted that the bulb holder 22 when associated with the head H and when the head is mounted on the container I8 projects in such a position with relation to the container that it serves conveniently as a handle for supporting the aerosol bomb and the push button 52 can be readily depressed by the thumb of the hand holding the bomb.
After the desired spraying yoperation the push button is released and the valve returns to closed position, the construction of the valve being such that there is positive closing against any leakage whatsoever and the bomb can therefore be used intermittently with long periods `of non-use yet it is always ready to use when needed. At the same time when the bomb is emptied of liquid this fact is denoted by the discharge of gas when the valve is opened and the bomb is made so that the head H can be unscrewed from the container l0 to recharge the bomb with liquid. The user can then unscrew the holder 22, insert a fresh gas bulb 24 therein and screw the holder back into position (about two or three threads farther to the right of the position shown in Figure 1) whereupon the neck of the bulb is pierced and the bomb is ready for use.
Some changes may be made in the construction and arrangement of the parts of my aerosol bomb without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modied forms `of structure or use of mechanical equivalents which may be reasonably included within their scope.
4 I claim as my invention: 1.
