' '1 Claims. (01. 299-48) The present invention relates to' a pocket atomizer for spraying perfumes or similar toilet liquids.

An object of the invention is to provide an atomizer of simple and economical construction wherein complicated parts such as check valves, operating latches, and other similar mechanism which heretofore has addedto the expense 'of manufacture and to the convenience of operation, are eliminated Another object of the invention is to provide an atomizer construction wherein the movable element is substantially enclosed and protected by the outer casing, and wherein the movable element which is operable to effect air compression and spraying action, is normally maintained in a position at the beginning of its air compression and spraying stroke, whereby the atomizer is always immediately ready to produce a spraying action without further manipulation or movement. g

Another object of the invention is to provide novel means for sealing the liquid containing reservoir when theiatomizer is not in operation in order to prevent any leakage or loss of liquid, Still another object of the invention is to provide means for properly aligning the parts which move with respect to each other both during movement, and while they are at rest.

Additional objects and advantages of the invention shall become apparent as'the following description proceeds. I

To the accomplishment of the foregoing and related ends, said. invention, then, consists of the particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain structure embodying the invention, such disclosed means constituting, however, but one of various structural forms in which the principle of the invention may be used.

In said annexed drawing:

Fig. 1' is an elevational view of the exterior of the atomizer embodying the principle of the invention; Fig. 2 is an elevational view taken upon a plane normal to that of Fig. 1; and Fig. 3 is a view of the upper exterior end of the atomizer; Fig. 4 is an elevational view in section; Fig. 5 is a detailed, partially sectioned view of the combined air compressing plunger and liquid container; and Fig. 6 is a sectional view taken upon a plane normal to that of Fig. 4 and substantially along line 6-6 thereof.

Now referring more particularly to the drawing, there is shown therein an outer cylindrical casing- -I, in which a combined air compressing and liquid containing member 2 is movably mounted. The member 2 is of a cylindrical contour in order to conform with the interior ofthe outer'casing I and can be fabricated from a molded, non-metallic material such as bakelite or a similar plastic compound, or from metallic material such as a die cast white metal. The

' lower end of the casing I is closed by means of a flanged end wall 3 which threadably engages the casing I as indicatedat 4. 'An air compression chamber S is thus defined in the lower end of the casing i by the bottom end of the member 2 and the bottom wall-3. A compression spring 6 is located. in the air compression chamber 5, bears against the bottom 3 of the casing I and the bottom of the member 2, and urges the latter in an upward position which is limited by the top end I of the casing I. The side and end walls of the casing i are partially removed as indicated at 8 whereby a portion of the member '2 is exposed. Thus the upper end 9 of the mem ber 2 is not surrounded and enclosed by the easing I whereby it serves as a bearing surface for the contact of the operators finger or thumb.

The interior of the member 2 is hollow and defines a liquid containing reservoir iii. A filler plug II threadably engages the wall of the member 2 and extends through the elongated slot I2 in the wall of the casing I. The elongated'slot I 2, together with the filler plug II, serves as means for guiding and aligning the member 2 when it is moved with respect to the casing I. A

liquid conduit tube I3 extends into the interior.

of the liquid reservoir I0 and terminates 'exteriorly of the member 2 as at I4. An air vent conduit I5 communicates with the upper end of the liquid reservoir I0. Both the upper end I6 of the air vent I5 and the upper end Id of the liquid conduit I3 are located in substantially the same plane and are adapted to bear against a resilient pad I! located in the end-1 of the casing I when the atomizer parts are in normal position. The resilient pad I! is composed of material such as rubber; thus it serves as a means for sealing both the liquid and air conduits extending into the interior of the liquid reservoir It. The pad I! is secured in the end 1 of the casing I by means of an inwardly extending flange I 8. The flange I8 is 'slightlyinclined towards the pad I! whereby the latter is compressed and thereby securely held in position.

A shoulder .or transverse face I9 is formed on the member 2 and adapted to bear against and A tubular air conduit 221s positioned centrally of the member 2. Its upper end is retained in an annular boss 2! extending inwardly from the top wall 9 of the member 2. A minute air passage 22 extends from the upper end of the air conduit 20 to a point in alignment with the upper end Id of the liquid conduit 13. The lower end of the air conduit 20 extends below the bottom of the memper 2 and through the bottom wall 23 thereof. The bottom wall 23 of the member 2 tightly fits in a groove as at 24. A compressible washer 28, composed of rubber or the like, tightly fits against the inner wall of the member '2, and effectively seals the interior thereof. A threaded nut 25 engages over the lower end of the air conduit 20 and secures a washer 26 and a flexible sealing gasket 21 to the lower end of the member 2. The sealing gasket 27 serves as means'for slidably sealing the member 2 to the inner wall of the casing I, thus forming in eflect a piston or plunger adapted to operate in the air compression chamber 5.

The operation of the device is as follows: Liquid perfume or similar toilet preparation is introduced into the reservoir 90 by means of removing the filler plug M. The atomizer is then ready for immediate use and operation. The operator grasps the upper end 2 of the member 2 and the bottom.wall 3 of the casing between the thumb and index or fore finger and thereby forces the member 2 downwardly, whereupon air willbe forced from the chamber 5 up through top of the liquid conduit 52. Such a passage of air across the top of the liquid conduit it produces an aspirator or suction efiect which draws liquid up through the latter tube from the reservoir I0 and ejects it in the form of a spray out through the elongated slot l2. Upon release of pressure, the spring it returns the parts to their original position as shown in Fig. 4 and seals the upper ends it and it of the liquid conduit l3 and air vent 85 respectively againstthe face of the resilient pad H. The air vent it permits the introduction of atmosphericpressure to the liquid reservoir Ill so that removal of liquid therefrom will not produce a vacuum which might prevent the passage of liquid up through the conduit 03.

' It should also be noted that the spray emanating mediately ready for operation and does not necessitate the manipulation of any locks, levers, or catches in order to free the movement of the parts or to eflect an opening of the various air or liquid conduits. The atomizer can be operated easily with one hand and after operation immediately returned to a pocket or purse without the bother of closing a cover, catch, or valve, or locking a plunger. It should also be noted that since the combined liquid containing and air compressing member 2 is normally in an outward position with respect to the air chamber 5, that the compression spring 6 is also normally in an expanded position. In this manner, the life of the compression spring is greatly increased, since it is subjected to full compression only when th atomizer is in operation. a

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the structure herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.
