(Cl: 25m-+95) 1 Claim.
. This" invention relates to a spraying-1device wherein an attachment isprovided foraV .bulb
containing a liquid to be sprayed from the bulb and a gas under pressure to effect the spraying operation.
One object of the invention is to provide an attachment which is very simple in that it has few parts and is therefore inexpensive to manufacture.
Another object is to provide an attachment which can be screwed onto the threaded neck of a iiuid pressure bulb and has therein a means to both puncture the bulb and serve as a valve for controlling the flow of liquid from the bulb.
Still another object is to provide a body member adapted to be screwed onto the threaded neck of a bulb containing liquid under pressure.
and having threaded therein a pointed element for puncturing the bulb when a knob on the outer end of the pointed element is turned in one direction, a gasket being provided outwardly of the pointed end of the element for holding the liquid until the element and the gasket carried thereby are screwed out to a position for uncovering a discharge orifice.
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 claim and illustrated in the accompanying drawings wherein:
Figure 1 is an elevation of my spraying device attached to a fluid pressure bulb;
Figure 2 is a sectional view on the line 2-2 of Figure l, showing the attachment being operated for puncturing the bulb;
Figure 3 is a similar sectional view showing the attachment adjusted for permitting the discharge of the spray therefrom; and
Figure 4 is a sectional view on the line 4 4 of Figure 3.
On the accompanying drawing, I have used the reference numeral I0 to indicate a bulb such as one of the Sparklet type having an externally threaded neck I2. The upper end of the bulb is closed as at I3 in the usual manner.
My spraying device comprises an attachment consisting of a body member I4 having an internally threaded part I6 to coact with the threads I2, a gasket I8 being provided to seal the connection between the body I4 and the threaded neck of the bulb. The body I4 is also provided with internal screw threads 2i! in which the threads 22 of a stern 24 are threaded. The inner `end of the stemis pointed as at26 and thetouter -end'is provided with a knurled knob 28. .A gasket 30'is mounted in' a groove 32 aroundthe' stem `24.
Within the body member I4 a shoulder 34 is provided for the gasket 3U to seat against when the parts are in the position of Figure 2. The body I4 is also provided with a discharge orifice 36 of small size so as to produce a spray when liquid under high pressure is discharged therethrough.
The bulb l Il is adapted to contain a liquid such as insecticide, perfume or the like to be sprayed and a charge of gas such as CO2 under pressure tor expelling the liquid when desired. The spraying device is adapted to first be connected with the bulb Ill as shown in Figure 1 and the point 26 is then utilized to puncture the upper wall I4 of the bulb as shown at I5 in Figure 2. This of course is accomplished by screwing the knob 28 inwardly.
After lpuncture of the bulb wall I3 is eiiected the knob is turned on down to a position with the gasket 3B compressed against the seat 34 t0 seal the parts as in Figure 2. and the bulb may be left in this condition indefinitely without leakage.
When it is desirable to use the spraying device for spraying the liquid from the bulb the parts are inverted as in Figure 3 and the knob 28 may then be screwed outwardly until the gasket 30 uncovers the orifice 36 whereupon the liquid will be sprayed out in the form -of an aerosol as illustrated at 38 in this ligure. The degree of spray may be regulated as desire-d by the amount the orice 35 is uncovered by the gasket 30. All of the liquid may be discharged or any part thereof in which case the gasket 30 is again seated on the shoulder 34 for sealing the remaining contents of the bulb against escape.
The spraying device as disclosed is obviously very simple and inexpensive to manufacture so as to provide an inexpensive unit for use in connection with bulbs containing various liquids under pressure to be sprayed therefrom. Its operation is simple and eiicient and the device may be reused a great number of times.
Some changes may be made in the construction and arrangement of the parts of my device without departing from the real spirit and purpose of my invention, and itis my intention to cover by my claim any modified forms of structure or use of mechanical equivalents which may be reasonably included within its scope.
I claim as my invention:
A spraying device comprising an annular body member, a stem movably axially therein, said annular body member having formed internally at one end thereof means for connecting therewithin the neck of a liquid containing pressure bulb having a puncturable diaphragm across the top thereof, a stop member within said annular bodi7 located inwardly of said connecting means, said stop member presenting an annular seat adapted to have positioned adjacent therewith the puncturable diaphragm of said pressure bulb, the inner end of said stem being pointed for puncturing said diaphragm, said stem carrying a gasket of iinite thickness spaced from the inner pointed end of said stem, portions of the stem overlapping portions of the gasket on both sides of the gasket, whereby the gasket is fixed axially on the stem, said body member having a shoulder spaced axially from said stop member and between said stop member and said gasket and adapted to have said gasket seal thereagainst, said body member having a discharge orce spaced axially from said stop member and spaced in the same direction axially beyond said shoulder a distance at least as great as the thickness of said gasket. the spacing of said discharge orifice from said annular seat of the stop member beingV greater than the spacing of the innermost portion of the gasket from the inner pointed end of said stem, whereby said discharge oriiice is covered by said gasket at the beginning of a puncturing operation of said diaphragm and thereby sealed off from communication with the bulb until subsequently uncovered by outward movement of said stem to permit the discharge of liquid from said bulb.
