This invention relates to atomizers and may' be characterized as'an improvement up-v on the'atomizer illustrated and described in Antony Thomas United Sta-tes Letters Pat- 5 ent No. 1,573,334, issued February 16, 1926.

The object of the presentinvention 1s the provision of a generally improved and s1m' plified construction that, ma be economically roduced and whichv wlll discharge ,a

l more nely atomized spray. v

The invention is illustrated inthe accom# panying drawings', in which 'p Fig. l is a plan view 'of a device embodyin my invention;

l Fig. 2 'is a face view inFig. l; .4

Fig. 3 is a section taken .on the line 3 3 ofF1g.1;and. 1' v Fig. 4 is an enlarged 4section taken on the l'ine4-4ofFig.2. f

Referring to the drawings,l the device shown comprises a casing 5 having flexible sides 6 and a relatively rigid frame-like portion 7. The frame and sides may be of metal, the sides being preferably of 'relatively exible sheet metaland the framelikeportion may be of circular 0r any other suitable or preferred configuration.

The casing 5 has an opening 8 which constitutes the lilling opening of the device. In the embodiment shown, this opening 8 is through the frame-like' portion 7 and is defined by a nipple l0. The nipple 10 is internally threaded at 11 to receive the lower threaded end 12 of a closure member 13.

A relatively small tube 15 extends s ubstantially centrally into the casing 5 and opens at its lower end at 16 into ,the liquid 17 to be sprayed, near the bottom ot the liquid. The opposite end of the tube 15 is turned laterally at 18.' The end of; the laterally turned portion 1S is secured at 19y to the side Wall of the closure member 13 with the relatively small duct or 'passage through the tube'15 opening out through the closure member 13 at 20. Within the space- 21 above the level of the liquid 17 the tube 15 has an opening 22 conveniently at the bend Where the tube 15 is turned laterally at 18, although this may of course vary as desired.

The closure member 13 is open at its lower end with its lower end externally threaded to be screwed into the iller opening 8C and its upper end externally threaded at 25 vof the device shownvscrewed'upon vthe upper 'end of the closure riphery of the' ycap 26.jmayfbe: knurled or otherwise'zfinished to be conveniently grasped sure member when .that vis desired.

to receivey a closure vcap '26.4 Between its l opposite threaded ends the closure member 13 has a 'radially extending lia nge-li'kevpcr-l tion 28, the periphery of' yWhich may ibe 6 0` lmurled to be conveniently grasped between the fingers for screwing the' closure member intov and from the openingS'.

VThe cap 26 is internally threaded to'be member 13 tov close the 'spray voutlet 20. VVhenin vclosed position upon the nipple '10,; the lower edge ofthe cap 26, iss'crewed' down upon 'the flange-,like "portion Y28.` The pe-v 70 between the' fingers vfor screwing it uponand 7 from the closure member andin actual practive the flange-like portion 28 preferably extends beyond the 'cap 26 .so that 'it may be 75 held againstV turning with kone hand while". y the cap 26 is threaded vfromthe closure mem` ber with the other hand, thusassuring removal of the cap without removing the clo- In use, the cap 26 is removable fromthe closure member 13 andthe closure member'l 13 with the tube 15 may be detached as a unit from the casing 5 by unscrewing the' closure member 13 from the nipple 10. lThe 85 casing 5 may be filled with the desired liquid through the opening 8 to substantially thelevel shown'in Figs. 3 and 4. The closure member 13 with its tube 15 may then be attached to the casing and when the sides 6 are pressed'together as, for example, in the hands of the user, with the cap 26 unscrewed from the closure member 13 suiciently to uncover theoutlet 20, the level of the liquid 17 in the casing'5 is raised for example from the line a-a to the line b--b in Fig.4 and va spray is discharged from the outlet 20. The normal condition of the sides 6 is shown in full lines in Fig. 4, and their pressed-incondition in discharging a spray, is shown in dotted lines in the same figure. This pressing in of the' sides 6 creates a air pressure in the space 21, the compressed air passing into the tube 15 through the opening 22.' AV lower pressure'is thus created inthe' tube l151'below" the opening 22 by the resulting aspirating action' 'ofthe air, and the -liquid 17 which is under pressure enters the lower open end 16 of the tube 15 and passes up through" the tube 'and out through the outlet 20 at the end of' thelatferally turned portion 18. lThe air passing at relatively high velocity through the upper end and laterally turned portion of the tube atomi/fes or breaks up the liquid passing up through the tube and the resulting discharge from the outlet is in the form of a finely atomized spray.

From the foregoing, it will now be apparent that the path of travel of the air is relatively short and that a more finely atomized or divided spray may be produced; also that the construction is simplified and adapted for economical quantity production.

`The device is operable to discharge kthe l spray laterally with the tube 15 in upright position which permits'application of the perfume or other contents laterally onto the person, handkerchief or the like Without Qturning the device into. position With the tube 15 horizontally disposed.

The closure is simple, the making up of the tube 15 as a unit with the closure nicnr ber 13 facilitating manufacture and assembly and the lateral opening Q0 not only permits a lateral spray Withoutleakage but in the device provided the opening 20 may be uncovered without completely removing the cap 26. l'

In an atomizer having a liquid container provided with flexible sides and a single leg tube depending within the container and terminating near the bottom of the inside thereof, said tube being provided with an opening communicating` with the interior of the container above the level of. the liquid therein, the combination of a closure comprising expose said opening Without removing 'the cap entirely from the closure member.

In witness whereof, I have hereunto set my hand this 1st day of June, 1926.
