June 20, 1933. J. B. SCHMITT ET AL PERFUME DISPENSER Filed May 25, 1952 Patented June 20, 1933 I UNETED STATES PATENT OFFIOE JOY B. SGHMITT AND PAUL B. BROWN, OF TOLEDO, OHIO, ASSIGNOBS TO THE DE VILBISS COMPANY, OF TOLEDO, OHIO, A 'CQBIOBATION OF OHIO PERFUME DISPENSER Application filed May 25,

This invention relates to a container which is primarily adapted to contain liquid perfume or the like and which is specially constructed with the object of providing simple means for selectively dispensing quantities of the liquid contained therein or for allowing a prospective customer to obtain a whiff of the contents without removing any of the liquid from the container and without removing the stopper.

The present embodiment of the invention will be more particularly described with reference to the accompanying drawing, in which Figure 1 is a central sectional view of the invention as applied to a liquid container;

Figure 2 is a front elevation of the same with a portion of the stopper shown in section as indicated by the line 2-2 of Figure 1;

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

The invention is illustrated as applied to a liquid container 5 having a stopper 6 which may be of cork or other sutiable material.

* The stopper 6 is provided with a core 7 in the form of a sleeve or bushing which is preferably provided with external threads and is screwed into the stopper 6. In the present embodiment of the invention, the member 7 has a reduced upper end 8 pro jecting above the stopper 6, thus forming an annular shoulder 9 at the surface of the stopper upon which a washer 10 is seated. This washer may be cupped, as shown, or may be of any other suitable shape.

A cap 11 is secured to the upper end portion 8 of the member 7 by means of a force fit or in any other suitable manner. The cap 11 is formed with an interior cavity 12 which is in communication with the passageway through the member 7. The upper portion of the cap 11 also is formed with a bore 18 which is in communication with an outlet tube 1% secured to the cavity. A tubular stem 15 is secured to the interior of the cap 11, preferably by means of a screw threaded connection16 and is disposed in alignment with the bore 13. The stem 15 has an extension 17 secured thereto and extending to a point near the bottom of the container 5. The external 1932 Serial No. 613,360.

diameter of the tubular stem 15 is less than i the internal diameter of the member 7 so that the cavity 12 within the cap has a free communication with the interior of the container 5.

An air inlet tube or pipe 18 is secured in any suitable manner to the head 11 and communicates with the cavity 12. The outer end of the air tube 18 is provided with a flexible bulb 19 or other suitable means for introducing air under pressure into the cavity 12 and thence into the upper part of the container 5. A nipple 20 is also secured in one side of the head 11 and provides communication between the cavity 12 and the atmosphere 265 except when the .end of the nipple is closed as, for example, by placing the thumb or finger over the end thereof.

In assembling the invention, the washer 10 is first placed in position on the member 7 and the head 11 is then secured to the reduced end 8 of said member. The member 7 is then inserted into the stopper 6 and the stem 15 inserted through the member 7 and connected with the head 11. The tubes 14 and 18 are then connected to the head. These various steps, however, need not necessarily be carried out in the order recited.

In the operation of the invention, if the nipple 20 be closed by the thumb or finger, a compression of the bulb 19 will, of course, introduce air under pressure through the annular passageway between the stem 15 and the wall of the core 7, and into the container 5 above the surface of the liquid therein This will force the liquid up through the tubular stem 15 and out of the discharge pipe 14. Thus any desired quantity of the liquid may be dispensed. Thus the container 5 may be used for containing perfume or other 2:.

liquid in bulk and from this container small vials may be filled. The flow of liquid may be stopped at any point by removing the thumb or finger from nipple 20, which im mediately relieves the pressure within the container.

If the nipple 20 be left open while the bulb 19 is repeatedly compressed, the air under the pressure thus created will be expelled from the opening in said nipple carrying with it a small amount of volatilized perfume which has mingled with it, either by being propelled by its own vapor pressure from the interior of the container through the passageway in the member 7 and hence into the cavity 12 and into the path of flow of air passing therethrough, or by contact with the air which enters the container under ressure created by the compression of the ulb, which expands into the cavity 12 during the interval before the next compression of the bulb and which is expelled with the flow of air created by the subsequent compression of the bulb. The size of the vent port through the nipple 20, the size of the bore of the member'7, and the size of air passageway 18 are so proportioned that when the bulb is compressed and the vent port is open, a slight pressure is obtained within the bottle, but it is impossible to create sufiicient pressure to force the liquid out of the delivery tube 14.

lVhile we have shown and described in detail the preferred construction of the invention, it is obvious that the same may be modified in respect to various immaterial details without departing from the scope of the invention as claimed.

Vhat we claim as new, and desire to secure by United States Letters Patent, is:

1. The combination with a liquid container, of a stopper therefor comprising a tubular core, a cap secured to and covering the upper end of the core and having a cavity of greater diameter than the internal diameter of the core, a liquid conduit secured to said cap and extending through said core and cavity with its lower end normally beneath the level of liquid in the container, a liquid outlet from said cap constituting a continuation of said conduit, :1 compressible bulb having an air passageway leading into said cavity and thence through said core outside of said liquid conduit, and a port affording communication between said cavity and the atmosphere and adapted to be closed by a persons finger.

2. The combination with a liquid container, of a stopper therefor formed with a cavity and with a passageway from said cavity to the interior of the container, said passageway being of less diameter than the cavit a conduit leading from near the bottom of the container through the stopper and terminating in a discharge nozzle, and a compressible bulb provided with an outlet into said cavity, said cavity having an atmospheric port adapted to be closed manually.

In testimony whereof we have hereunto signed our names to this specification. I JOY; B. SCHMITT.
