Application September 10, 1940, Serial No. 356,151

(Si. 299-89) This invention relates to pocket spray devices 1 Claim.

and more particularly relates to atomizers and spray devices for perfumes, cosmetics, medicinale and the like, having parts which can be fitted into approximately the size of an ordinary fountain pen or pencil, and thus when carried will simulate a pen or pencil both in size and in shape.

It has previously been proposed to provide spray devices which allegedly can be carried in the pocket of the user, but such devices have either been bulky, and thus inconvenient to carry, or, even if of small enough size to render carriage convenient, have been leaky and thus impractical for the purpose intended.

It is an object of this invention to provide a pocket spray device ywhich may coveniently be fitted within an outside casing of substantially the size and shape of an ordinary fountain pen.

It is a further object of this invention to provide a spray device having a combination of parts which will produce a finely divided spray of the material stored in the device, which parts may be mounted within a casing substantially the size and shape of an ordinary fountain pen.

It is an object of this invention to provide a pocket spray device having the liquid containing portion and the air containing portion completely separable so that the two parts may be carried separately and may be replaced individually so that loss or destruction of one part will not ne cessitate discarding the other part.

It is a further object of the invention to provide such pocket spray device or atomizer which will be completely leak-prooi when not in use.

It is a further object oi the invention to provide a pocket spray device which may be simply and conveniently operated.

Further objects and advantages will appear from the following description and the drawings appended thereto in which Figure l is a longitudinal section of a Spray device embodying the principles of this invention;

Figure 2 is a longitudinal section of a modified form of spray device;

Figure 3 is a section taken on the line 3 3 of Fig. 1;

Figure 4 is a section similar to 1 of a modi iied for-m of spray device;

Figure 5 is a section similar to l oi further modiiicaticn; and

Figure 6 is an enlarged sectional view of a part of Figure 5.

Referring particularly now to Figure l., a construction is shown having an outside casing E! which is generally cylindrical in shape and is preferably constructed approximately the size of a customary pocket pen or pencil. The casing I i consists preferably of the top cap I2 which is hinged at I3 to swing open and which contains the gasket I 4 which may be of rubber or any other convenient insulating material. The cap may be held in closed position :by any convenient means such as the snap catch shown which includes the resilient finger 9 which snaps over boss IIi. The casing II also includes the upper cylindrical portion I5, lower portion I6 which may lbe connected to portion I5 as by threads il, and the bottom member I8. If desired the clip member I-Q may be provided for convenience in carrymg.

Near the bottom of the upper portion E5 of the casing II is provided the closure member 2l which is threaded into the member I5 and provides a liquid seal at this point in the casing. The top portion of the casing I5 is provided with the closure member 22 which is also threaded into the interior of the casing I5 providing a liquid seal. The casing I5 and the top and bottom closures 2| and 22 define the liquid containing compartment 25. Threaded plug 26 screws into the closure member 22 and may be removed for refilling the liquid reservoir. The `tube 2"! is inserted into the liquid reservoir, its lower end terminating in the lower portion of the reservoir in the curved portion 28, and its upper endextending through the closure member 22 and terminating substantially flush with the top of the cap. The curved portion 28 of the tube 21 insures that no leakage will occur out of the top of the tube when the atomizer is not in use, as nc matter what position the reservoir is placed in, no leakage will occur if no air is allowed to enter compartment 25. In addition the rubber gasket I4 doubly insures the absence of leakage.

To provide for atomizing the liquid in the container 25 the piston 30 is mounted within the lower wall I6 of the container II. The piston is secured to the plunger 3I which extends downwardly through the bottom member I8 of the outside casing, and is provided at its end with the thumb piece 32. The spring 33 tends to draw the piston inwardly and preferably is provided with just suliicient strength to hold the piston, plunger and iinger piece in position inside of the casing I6 when the device is not in use. The piston includes the cup member 35 and cup member 34 which may be of leather placed back to back. The member 34 mounts the valve member 3S. The valve plate 38 is limited in its upward movement by lingers 31 and the hair spring 39 tends to push the valve plate 38 downward. Port 4E! is provided extending through the members 36, 34, and 33.

The tube 45 is provided extending from closure member 2! through the liquid containing chamber 25 and terminating in an outwardly turned portion 45 which is directed over the top end of the tube 2l. The curved air connection 4'1 is provided near the top of the tube 45 to permit air to enter the liquid compartment 25 to compensate for the removal of liquid so that a vacuum will not obtain within the chamber 25, thus preventing the removal of liquid. The curved member 41 insures that no leakage will take place .through this air vent no matter the position of the device, and the gasket I4 further insures from undesired leakage.

The operation of the device is simple. The plunger 3| is drawn down, the valve plate 38 moving up against the annular ange 31 and permitting air to pass. The plunger 3| is then pushed up and valve plate 3B seals the port 40, thus sending air at high velocity through the tube 45,

which in passing over the end of the tube 21 draws liquid from the liquid chamber 25 according to atomizer principles. The displacement of liquid in the chamber 25 is compensated for by reintroduction of air through the tube 41 and the device will operate smoothly and continuously, the liquid being atomized in a ne spray which may be sprayed in any desired direction by the operator.

In Figure 2 is shown a construction of atomizer which is adapted to be confined in a tube of the same cross sectional diameter, but which may conveniently be reduced in longitudinal dimension. No further description of the liquid chamber and atomizing means is necessary, reference being made to Fig. 1 for this construction. The construction for producing the blast of air at the opening of the tube 45, however, includes the cylindrical member in which is conned the piston 3|) as shown. The plunger 3| is secured to a cylindrical member 5| of a diameter adapted to t snugly over the cylindrical member 56 in sliding substantially air tight relationship. Spring 52 tends to retract the plunger 3| and has just sucient strength to hold the same in retracted position. The device may conveniently be operated by up and down movement of the outside cylinder 5|.

An alternate construction is illustrated in Fig. 4 wherein the plunger 3| and cap 32 will be located at the top of the construction comparable to the top of a fountain pen when the device is in non-operative position. The construction is similar in operation and construction to that shown in Fig. 1 and diiers only in modified location of parts. Thus the casing 66 which is comparable to the upper portion l5 of the casing Il of Fig. l, is eXteriorly threaded at its top. The casing 6|, comparable to the portion |6 in Fig. 1 and in the rest position of the device inverted over the top of casing 66, is provided with the interiorly threaded portion 64 into which the threaded portion of the casing 60 is screwed. The gasket 65 seals the liquid and air openings of the tubes 45 and 21. The lower portion of casing 60 is exteriorly threaded at 61.

To place the devicein operative position the casing 6| is unscrewed from the top of casing 53, inverted and screwed to the bottom portion at 61, whereupon the device operates in the manner described in connection with Fig. l. The advantage of this construction lies in the fact that the plunger 3| with its cap 32 is thus kept away from the bottom of the users pocket and further that the liquid and air openings are positively sealed within the casing and do not depend tc any extent whatsoever upon the presence of a hinged cap member, as shown in Fig. 1..

A modied construction of spray device is illustrated in Figs. 5 and 6 in which the means for producing a blast of airare the same as that described in connection with Figs. 1 and 4 and thus require no further description. This construction, however, is particularly directed to a device which will permit spraying of liquids of greater specic gravity than those for which the constructions of Figs. 1 through 4 are especially adapted, and to this end the liquid reservoir 1l) -is provided, including the cylindrical casing 1|,

the top closure 12 having reiill plug 13 and the bottom closure 14. Tube 15 is directly connected to the source of air. It has a descending portion 15a, an ascending portion 15b and a descending portion 15o which extends through the plate 14 and turns outwardly to the portion 16 of enlarged diameter. The enlarged portion 16 contains a screw 11 adapted to revolve freely in the portion 16.

The portion 15b of the tube 15 contains holes 18 and 19 one of which will always be below the liquid level, except when the liquid in the reservoir is substantially exhausted, and one of which will always be in the air space above the liquid level. These holes serve a combined purpose. Air entering through tube 15 will, in the position of the spray device shown in Fig. 5, blow out of hole 19 displacing some of the liquid into the tube 15. In the event that the removal of liquid from the liquid container is insufficiently compensated for so that a vacuum is formed, air will also escape from 19 and permit continuous removal of the liquid, thus providing an even'delivery of spray from the portion 11. The two holes 18 and 19 further insure that the device will operate in any position in which it is held.

The cap 36 hinged at 8| is similar to the cap l2 of Fig. 1, the gasket 82 being adjusted to ac` ccmmodate the open portion of the screw spray device. The reservoir 10 may be refilled by removing it from the piston containing portion 64 and unscrewing the plug 13.

It will be observed that in all forms of the invention the liquid containing portion forms a complete leakproof unit which may be carried separately from the piston containing portion. Either portion may be replaced if lost or destroyed thus saving the expense of obtaining an entire new device.

While I have illustrated and described in detail certain preferred forms of my invention, it is to be understood that changes may be made therein and the invention embodied in other structures. I do not, therefore, desire to limit myself to the specific constructions illustrated, but intend to cover my invention broadly in whatever form its principle may be utilized.

I claim:

A pocket atomizer comprising a pair of members separably connected end to end, the rst of said members having storage means for storage of liquid, the second of said members having air compressing means including a piston, a plunger to operate said piston, said plunger having a cap, said cap comprising a cylindrical member snugly slidable over said second member to actuate said piston, means in said rst member to conduct air compressed by said air compressing means under high velocity to the end of said first member remote from the connective end of said member, a tube in communication with the lower portion of said storage means and mounted in atomizing relation to said air conducting means at the end of said rst member remote from its connected end, said air conducting means having communication with said liquid storage means in the upper part thereof.
