TOLEDO, 01110, A ooaromrrron or orrro Application filed April 10,

This invention relates to an atomizer particularly adapted to be attached to a receptacle containing perfume or other liquid.

One object of the invention is to provide a spraying device so arranged that the receptacle, in connection with which it is used, and also the liquid outlet passageway leading therefrom are normally completely closed, so that none of the volatile contents of thereceptacle can evaporate and'esca-pe into the atmosphere, yet the liquid passageway may be instantly opened, when desired, to perm t the spraying device to be used. For this purpose, the liquid passageway is controlled by a yieldably held manually operable valve, and in its preferred form a stop is also provided, which may be adjusted to lock the valve to its seat and thereby prevent accidental escape of the contents of the receptacle when the latter is packed in a traveling bag or the like. In the present embodiment of the invention, a vent is also provided in the top of the receptacle, and is normally closed'by a spring held air valve, which is automatically opened at the same time as the liquid outlet valve, to permit relief of the partial vacuum caused by. the flow of liquid from the receptacle.

The above and other advantages of the invention will be more particularly explained in connection with the accompanying drawings which illustrate one embodiment thereof. i

In the drawings: I T

Figure 1 is a'vertical sectional view of the atomizer as appliedto a liquid receptacle.

Figure 2 is a section taken on the line 2-2 of Figure 1.

I Figure. 3 is a section taken on the line 33 of Figure 2.

As illustrated in the drawings, the atomizer is used in connection with a liquid receptacle 5, of glass or other suitable material, which has a metallic collar 6 secured to its upper end. The edge of the collar 6 is preferably lined with a'lead washer 7' and is internally threaded to receive the correspondingly threaded extension 8 of the head 9. The head 9 is formed with a central vertical bore 10, the lower portion of which constitutes a 1929. Serial No. 353,943;

liquid outlet passageway. The lower end of the bore 10 is enlarged to form a chamber 11 to receive a valve 12 which controls the dis charge of the liquid from the receptacle and is adapted to seat against the shoulder 13.

The valve 12 istormed with a stem 14 extending upwardly through the bore 10 and the bore, or at least its lower portion, is appreciably greater in diameter than the diamv also preferably has a threaded connection with thestem 14, whereby it may be adjusted tightly against anannu'lar flange 18 at the upper end of the head 9 to lock the valve 12 against the seat 13 and thereby prevent any possible escape of the contents of the receptacle when the latter is packedin' a traveling bag or the like. A sleeve 19 is secured to the head 9 at the lower end of the chamber 11 and has a tubular extension 20 of glass or other suitable material secured to its lower end and extend ing substantially to the bottom of the receptacle 5. A coil spring 21 is disposed within a recess 22 formed in the head 9 and bears against the collar 16 to hold the valve 12 normally against its seat. V The head 9 is providedwith a lateral air inlet tube 23, having a suitable fitting 24 connected'to its outer end-and adapted to be connected to a rubber bulb orother source of air pressure. The tube 23 has a continuation 25, which extends transversely through the head 9 and through a slot 26 formed inthe stem 14. lhe head 9 also has an extension27 encompassing the outlet-end of the tube and spaced therefrom to provide an outlet for the liquid from the chamber 11. The extension 27 is provided'with an outlet port 28, in alignment with the tube 25, so that air forced through the latter 'will be mixed with liquid drawn through the 'tube20 and 1 chamber 11 and will be discharged in the form of spray from the port 28.

A vent may alsobe'provided to maintain substantially normal atmospheric pressure within the receptacle as liquid is discharged therefrom through the outlet 28. Such a vent is shown at 29 extending vertically through the head 9 beneath the collar 16. This vent is normally closed by a valve 30 which is held by a coil spring 31 acting be tween the valve and a'bushing 32 secured within the extension 8. The valve 30 has a stem 33 extending upwardly into close proximity to the collar 16 and adapted to be engaged by the latter to open the vent simulta neously with the opening of the liquid outlet valve 12. V 7 From the foregoing description, it will be seen'that the valves 12 and 30 are both held normally closed by the respective springs 21 and 81, so that there is no possible chance for the liquid to escape by evaporation from the receptacle when the atomizer is not in use, yetby a slight pressure on the cap 15, both valves may be opened so that the atomizer may be used. ,At the same time the collar 16 closes tightly against the seat 17, thereby dispensing with the necessity of providing packing'for the outer portion of the stem 14. The adjustability of the cap 15 to engage the rim 18 and thereby to lock the valve 12 to its seat, at the same time preventing the valve 30 from opening, is also an important consideration when traveling.

While I have shown and described in detail the preferred embodiment of the invention, it is to be understood that the same may be considerably modified without any material departure from the scope of the in vention as defined in the appended claims.
