1 claim. (o1. 22a-394) My present invention relates to a liquid dispenser for spraying liquid in the form of an aerosol from a container 'of insecticide or the like.
One object yof the invention is to provide a dispenser of this general type having a cheap throw-away container for the liquid to be dispensed, ysuch container being a standard drawn or seamed can such as used for beer and the like and Adesigned for the use of a closure cap of the crown type.
Another object. isr to provide an inexpensive assembly of valve structure and syphon tube attachable to the crown cap of the container when it is desirable to dispense the contents thereof, and detachable therefrom after the contents 'are dispensed whereupon the valve and syphon tube assembly can be applied to another container of liquid.
. Still another object is to provide a gasket of neoprene or the like within the crown cap, the cap having an opening through which the syphon tube may lbe extended, the lower end of the syphon tube being sharpened so as to pierce the gasket in such manner that the gasket seals around the syphon tube to `prevent leakage of gas under pressure at this point thus retaining the pressure in the can for future spraying operations if the initial one does not result in dispensation ofthe entire contents of the can.
. A further object is to provide the valve struc-V ture with ya snap-on base that can be associated With or readily removed from the crown cap of the liquid containing can.
Still a further object is to provide a novel valve structure particularly adapted for the type of dispensing device here under consideration which is inexpensive to manufacture and yet reliable in operation.
With these and other objects in View, my invention consists in the construction, arrangement yand combination of the various, parts of my device whereby the objects contemplated are "attained, as hereinafter more fully set forth, pointed out in my claim and illustrated in the accompanying drawings, wherein:
Figure 1 is a plan View of a liquid dispenser embodying my present invention.
Y Figure 2 is a side elevation thereof with the container shown in section.
Figure 3 is an enlarged sectional view on the line 3-3 of Figure 1 showing one form of valve structure.
Figure 4 is a detail sectional view on the line 4-4 of Figure 3.
Figure 5 is a plan view of a similar dispense showing a. modified type of valve.
Figure 6 is a side elevation of Figure 5.
Figure '7 is an enlarged sectional view on the line 1 1 of Figure 5; and
Figure 8 is an enlarged sectional view on the line 8 8 of Figure 3 showing the top wall of la crown cap and a gasket associated therewith before the gasket is punctured as in Figure 3.
On the accompanying Vdrawings I have used the reference numeral IB to indicate a cheap disposable can of the type now generally used for containing beer and other beverages. This type of can is inexpensive to manufacture and may with economy be thrown away after using.
The can Io has a rolled upper edge I2 on which is normally positioned a crown cap I4. OrdinarilyV a cork disc is placed Ibetween the crown ycap and the upper edge I2 of the can to serve yas a liquid-tight seal. I propose to substitute for this cork disc a ydiaphragm or disc I6 vof neoprene, rubber or the lik-e to serve as a sea'ling gasket capable of holding the contents of the can under pressure. l
The contents of the can may consist of insecticide, germi-eide, fungicide, air cleaner, or
deodorant liquid or the like indicated at I 8.'
Above the liquid I8 is a space 2D adapted to Icontain Freon 11, Freon 12 or other gas under pressure for displacing the liquid I8 from the can, as will hereinafter appear. A can of the character disclosed I have found to be capable of withstanding an internal pressure of 300 to 325 pounds per square inch ultimate, which is sufficient for dispensing all the liquid in the form of an aerosol spray.
In Figures 1 to 4, I illustrate a valve and syphon tube yassembly comprising a spring clip 22, la syphon tube 24 (capillary type), a valve cap 26 and a lever 28 for opening the valve. The tube passes through a hole in the center of the clip 22 and is soldered thereto. The lever 28 is pivoted on -a pin 3i! carried by a pair of ears 32 u-pstanding from the sides of the clip 22.
The valve cap 26 is riveted to the lever 28 and includes a. cavity 34 having therein a sealing disc 36 and a packing washer 38. The packing washer is held in position 'by a flange 40 spun inwardly from the lower end of the cap 26. The cap 26 is provided with a minute discharge opening 42;
The lower end of the syphon tube 24 is sharpened by cutting it at an angle as shown at 44 so that the sharpened end after passing through an opening 4B at the center of the crown cap I4 is capable of `entering a socket I9 slightly smaller than the tube and piercing `a thickened portion or boss l1 of the neoprene disc I6 as shown in Figure 3. Figure 8 shows the condition of the parts before piercing. After piercing the boss Il closes around the tube 24 to seal 01T the interior of the container I0 to latmosphere around the syphon tube. The Ainternal pressure in the space 20 aids in this sealing action.
The valve cap 25 is normally in the closed position of Figure 2 due to the'a'ctioniof a'spring 48 Wrapped around the -pivot pin 3U and having its ends contacting with the spring/clip 22 and the lever 28 as shown in Figure 3.
In Figures 5, 6, and 7, I show a modie'd oonstruotion wherein the syphon tube "24 is .soldered into a valve body 50, the valve body in turn being soldered to aspring clip 22a. The valve body 50 has an annular valve lip 52 and avalve disc" 35a 'to seat again-st it whenfa-va'lve plug 54 carryingthedisc is'screwed' inwardly.
The valve plug, 'it will be noted, is `screw threaded in relation to the'valve body-'50 and an ring 55 may be provided as fa-'means'toseal against liquid Viiow through the threads of the valve. The valve body B is provided 'with a discharge opening Ma. To ,prevent the 'plug t'irom-beingfscrewed entirelyout, the upper end of the valve body 5t is "spun'inwardly as shown at 58.
Practical operation In the operation o'i the type of'dispenser shown iii-'Figures 1 t0`4,'aiter the syphon tubetvis'insei-ted throughthe opening-"6 of the crown Mit pierees'the portion i1 of the gasket IG rand permitsthelsyphon tube to be lowered to the position shown in 'Figure 2 with'the valve and tube assembly held on' thecrown'cap by the :ends of' the-spring'clip 22 snapping over opposite edges thereof.
'Thereafter when it is desirable to .dispense liquid the right hand end of the lever' is depressed 'as inFigure v3 thus unseatingtheldisc 35 from-the upper end of the oapfillarytube. which acts Ials a valveseat. v'The liquid 'thenilowsnnder pressuremto the :cavity 3d andl outlthrough'the o'p'eningaf,V itz being inhibited from: new around the tubelZ atithe lower end'of'ithe valvecapii by the' packing washer k3S.
Due l:to 'fthe pressure at which the =liquidxis forced outwardlylthroughthezopeningzandithe minute sizeiof theiopening'the' liquid is' atomifze'd oribreken'rupiinto4 very Ynineipartieles: soithati'its issue is in the form of a mist'or vapor oommony tl'medlaerosol. .'Thisf typenof spray is desirable for: insecticides 'and' the like asfitfeiects '-a suspension of the `liquid in the air so that it can penetrate-.tortelli crevices where' insects may be.
11n. the,l typerof valve structure shown in: Figures 5,-6and' 7 itqisv merelyL necessary to rotatethe knurled head on' the upper end ofthe valverplug 54 in one* direction for unscrewi'ng .the plug-ras in Figure 7 thus 4spacing' the disc13i`fromathe valve lipf52 torpermitiiuid flow totheY discharge openingel'a. ,'-After the desired quantity of liquid has beenk dispensed the valve .plug is screwed inwardly again Ato the seated position.
After the liquid I8 has been completely dispensed the can I0 can be thrown away after the valve and syphon tube assembly has been removed therefrom. This assembly -can then be associated with another can of liquid and gas under pressure and the valve thus re-used in connection with a great number of cans.
YThe valve structures shown are comparatively simple and inexpensive"tomanufactureand can thus be sold at small cost. The containers IU are also inexpensive thus eliminating the usual bother ofreturning containers for refund. At
the same time the container has sucient strength to withstand a pressure high enough to eiect dispensation of all the liquid with sufficient pressure to insure *an aerosol type spray.
The valve and tube structures disclosed are rugged enough to be associated with heavier containers and te control the ow of liquid at considerably higher pressure than a can type of container 'is vcapable of rfcontarning.
:Some .changes maybe made. in"` theA construction andv arrangement of -theparts ofrny device without departing from the real spirit and purpose ofmy invention, and it. is myintentionrto cover Yby myclaim'any modiiedforms of: structure or. use of 'mechanical equivalents which may be reasonably included withinrits; scope.
