STATES EDWARD CHARLES PETCHER, OF ST. LOUIS, MISSOURI.

ATOMIZER.

Application filed April 26, 1921.

To all whom it may concern:

Be it known that I, EDWARD C. PnroHER, a citizen of the United States residing at (now) St. Louis and State of Missouri, have invented new and useful Improvements in Atomizers, of which the following is a specification.

This invention comprehends the provision of an atomizer, which is very simple in construction, eliminating the bulkiness and cumbersome arrangement of parts embodied in the atomizers in general use, one that can be used for spraying throats, or adapted for perfumes where a few drops are necessary, and particularly advantageous for use by tourists, the invention being sanitary due to the fact that the atomizer tube is normally arranged in the solution.

The chief characteristic of the present invention resides in providing a combined liquid chamber and atomizer tube adapted to be normally arranged within a bottle or other suitable container for the solution, the tube being equipped with means for drawing in the desired quantity of solution and subsequently discharging the solution from the tube in the form of a spray, after the tube has been removed fromthe container.

Another object of the invention resides in equipping the combined chamber and atomizer tube with means for supplying the container with air incident to the removal of the tube from the container, thereby eliminating suction and making it very easy to remove the tube from the container when desired.

The nature and advantages of the invention will be better understood when read in connection with the accompanying drawings, the invention residing in the construction. combination, and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views and wherein:

Figure 1 is a vertical sectional view through the atomizer constructed in accordance with my invention.

Figure 2 is a sectional view taken on line 2-2 of Figure 1.

Figure 3 is a detail view partly in section of the stopper for the container.

Figure 4 is a detail view of the valve retaining element.

Specification of Letters Patent.

Patented July 11, 1922.

Serial No. 464,617.

Figure 5 is a detail View of the two-part button used in connection with the air bulb.

Figure 6 is a detail view of the combined chamber and atomizer tube removed from the container.

Figure 7 is a plan view of the valve.

Referring to the drawings in detail, 10 indicates the container for the liquid which may be constructed from any suitable material and of any desired configuration, the container being equipped with a stopper of the construction illustrated in Figure 3. This stopper is preferably constructed of rubber including a hollow tubular portion 11 and a flange 12 which is curved downwardly as at 13 and in its normal position terminates in close proximity tothe body 11 of the tube. lVhen applying the stopper to the container 10 it is necessary to stretch the flange and its downturned portion over the head at the mouth of the container, and in this manner the stopper is effectively held in position upon the container.

The combined chamber and atomizer tube is illustrated at Figure 6 and is preferably constructed of glass, although any other non-corrosive material may be used. This element comprises a hollow tubular body portion 14 which is of uniform diameter throughout its length except for the tapered extremity 15 which is positioned within the container 10, and the shoulder 16 which reposes upon the stopper 11 when the said tube is positioned within the container 10 as illustrated in Figure 1. The tube is provided with alongitudinally disposed air passage or channel 17 which opens at both ends of the tube, this channel being arranged substantially at a right angle to the outlet opening 18 at the lower end of the tube for a purpose to be hereinafter described. The interior of the tube defines a chamber 19 which merges into a restricted passage 20 adjacent the upper end of the tube as shown. The tube projects a slight distance above the shoulder 16 and is closed and sealed by the cement or the like 21, a valve retainingelement in the nature of a metallic plate 22 being imbedded in the cement and formed to provide a depending portion 23 which bears against a valve 2% to normally hold the latter seated upon the internal shoulder 25 formed in the tube immediately above the restricted passage 20 thereof. This valve is flexible, being preferably constructed of rubber and has its periphery notched as at 26 to provide air passages which communicate with an air outlet port 27 at one side of the tube. A 5 float valve 28 operates within the chamber 19 so as to prevent the escape of the solution which enters the chamber through the port 18.

Carried by the exposed end of the tube 14 is a compressible bulb 29 whichcommunicates with the air channel 17 of the tube, this bulb being provided with an opening in lthe top which is closed by a two-part button, the respective parts being indicated at '30 and 31 respectively. The part 31 which enters the part 30 and is formed with 1 bendable prongs to hold the button associated with the compressible bulb, while the part 30 ofthe button is provided with slots 32 which admits air to the bulb as will be understood. The opening in the top of the bulb is normally closedby a flap valve 33 which is arranged beside the bulb, the button above described being provided to eliminate dirt, dust or other foreign matter from entering the container 10 through the bulb 29.

The combined chamber and atomizer tube above described enters the container 10 through the stopper 11, during which time a portion of the solution contained in the bottle enters the tube through the opening 18. If the chamber does not fill with the solution, and you desire more of the same within the tube 14, it is only necessary to compress the bulb 29 forcing air into the container through the channel 17 thereby forcing the solution into the tube 14. The float valve rises with the solution until it reaches the position occupied in Figure 1 which closes the upper end of the chamber and prevents the solution from passing through the restricted passage and out through the air port 27. When it is desired to use the atomizer, the tube 14 is supplied with the solution in a manner just described, after which the combined chamber and tube 14 is wholly removed from the container 10. The solution in the tube can then be discharged through the openlng 18 by compressing the bulb 29 as w1 ll be readilv understood. lVhen the tube is initially inserted into the solution, the air passes up through the chamber 19 and past the float valve in advance of the solution and flexes the valve 24 so that this air is permitted to escape through the port 27. When the tube is being drawn or removed from the contalner 10, air is forced down through the channel 17, to supply the container 10 with the proper quantity of air in order to eliminate suctlon, and then permit the tube to be easily removed from the container when its use is. desired. The invention provides thevery handy atomizer, which can be conveni- Y 9 F fly a r nged in. a su tcase or the like, and

eliminates the cumbersome arrangement of the parts as embodied in atomizers of present day use. It is desired to have it understood that the combined chamber and tube 14 can be constructed in any suitable size to vary its capacity without destroying the general appearance of the atomizer.

VVhileit is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is'herein shown and described, and that Such changes may beresorted to when desired as fall within the scope of what is claimed.

What I claim is: p 7

An atomizer comprising a container, a combined chamber and atomizer tube normally positioned within the container and adapted to be removed therefrom for use, said tube having an air channel, a compressible bulb carried by the tubeand communicating with said container through the air channel and a valve controlled air escape port for said tube.
