ATTOR HEY Patented Nov. 20, 1951 UNITED. STATES PATENT OFFICE 2,575,632 NORMALLY SEALED ATOMIZER Elmer Lipman, Detroit, Mich. I Application April 27, 1950, serial No. 158,527

4 Claims. (Cl. 299-88) The present invention pertains to a novel atomizer designed particularly for cosmetic use but also suitable for medicinal purposes.

T1 le conventional cosmetic atomizer is normally open to atmosphere through both the liquid passage and the venting passage. Consequently there is a constant evaporation of the liquid, especially the alcohol or other volatile solvents employed. The resulting concentration, particularly of a perfume or toilet water, produces a solution that is foul smelling and also injurious to fabrics. This condition is not only disagreeable to the ultimate user of the atomizer but is also detrimental to sales in stores where an atomizer containing a sample prefume or toilet water is kept on the counter.

' Further, because of its constantly being open to the atmosphere, the conventional atomizer leaks when tilted and therefore is unsuited for traveling.

The principal object of this invention is to overcome these difiiculties and is accomplished generally by providing an atomizer that is normally sealed both at the liquid passage and at the Venting passage. These passages are opened for use by pressing the head of the atomizer against a spring incorporated in the assembly. More particularly, the head is attached to a ported valve member cotrolling both of the named passages but normally obstructed against packings or other sealing means by the expanded spring. Manual pressure on the head, as described, opens these passages to permit operation of the device.

Another advantage of the invention in this connection is that the novel atomizer cannot be used, without authorization, by children, employees, guests and strangers, since there is no outward indication that the head must first be pressed I against the action of a concealed spring.

The invention is fully disclosed by way of example in the following description and in the accompanying drawings in which:

Figure 1 is a plan view of the atomizer;

Figure 2 is a side view;

'Figure 3 is a section on the line 33 of Figure 1; showing the device in operating or discharge position; 1

Figure 4 is a similar section showing the atomizer normally sealed.

Reference to these views will now be made by use of like characters which are employed to designate corresponding parts throughout.

In Figure 1 is shown an atomizer applied to a bottle I by means of an adapter 2 which is a portion of the mechanical assembly of the atomizer.

The adapter is a tubular member having at its lower end a reduced nipple 3 that is fitted suitably on the neck 4 of the bottle.

In the adapter is mounted a slide or plunger 5 of considerably smaller diameter than the interior of the adapter and having its lower endformed with a flange or shoulder 5 which re mains'spaced from the inner wall of the adapter to permit flow of liquid as will presently be described. A tube 1 extends integrally upward from the top of the slide and has its upper end threaded at 8 for attachment of an operating member as described hereinafter. I

A packing ring 9, preferably with'an upper conical surface II], is fitted around the member 5 at the flange 6. The adapter also contains'the lower end of a core H formed'with an 'interme diate collar I2 which rests on the upper end of the adapter." The core is shaped as a hood hav ing a top I3 which slidably encloses the tube 1 below the threaded end. Beneath this top is fitting another packing I4 which rests on an in-' ternal shoulder l5 formed in the core il in a' position to be normally engaged by the top of the body of the plunger 5.

A head [6 is screwed on the upper end of the tube 1 and is formed with a skirt l! in the nature of a cap surrounding the collar [2 at a clear-' ance of about .01 inch. A coil spring I8 rests upon the collar [2 and bears against the bottom of the head [6 to bring the body of the plunger 5 against the packing I4 and also to bring the top IE or the packing 9 against the conical lower end IQ of the core ii. The head I6 is formed as a mixing chamber 20 into one end of which is fitted an air compressing bulb 21 in the usual manner. The other end of the chamber is closed except for a small port 22 which constitutes the spray outlet.

The slide or plunger 5 is in fact a valve govern; ing the flow of liquid out of the bottle and the flow of venting air into the bottle. A central cavity 23 is formed in the plunger from the lower end thereof and receives a tube 24 which is ex tended nearly to the bottom of the receptacle l directly or bymeans of a wick 25. From this cavity extends a port 26 tothe top of the plunger.

. 3 29 extends through the lower edge or wall of the core H to a point above the packing 9.

Normally; the expanded spring l8 lifts the head l6 and attached plunger 5 until the packing 9 engages and closes the lower end of the vent port 29. At the same time the tube I is lifted until its support 27 is obstructed within the packing 14, thereby closing the chamber 20 and outlet port 22 fromthe interior of the receptacle 1.

In this condition, which is the normal idle cendition of the atomizer, there can be no evaporation through the liquid channel or through the venting channel. In this connection, as previously stated, it is well known that the concentration of a perfume through evaporation of the alcohol causes it to become foul smelling and also injurious to the clothing. This difliculty is "of course overcome by the normally sealed atomizer disclosed herein. Again, the atomizer is iess sub ject to waste of theconte'nts through unauthorized tampering by camara erie guest's; Another and important advantage of this device is that it can be carried in luggage without any special precaution against leakage. Y 7

When the atomizer is to be used, the head I6 is pressed down with the thumb of one hand to lctver thje plunger 5 while compressing the spring |8. The ports 2"! and 'Z'Sare thus uncovered on beingireed from the respective packings l4 and 9. The'bulb; I is then operated by the dther'hand in 'the usual manner. v Y

The suction created in the chamber 2!] permits liquid from the receptacleto flow upward through the tube 2 4, chamber 23, port 25, tnes ac'e'new existing between the top of the plunger and the tlie'bottom o'f'the packing 24, the port '21, tube 1, andichamb'er 20 to be sprayed through the out"- let 22. Venting occurs thrbug'h the clearance between the skirt l1 and collar I2, the groove 2 8, port 29, the space between'tlie lower end of the core 11 and the taper the packing 9, the space between the flange 6 and the iii'ner'wall of the adapter 2, and thence thrbugh the nipple 3 to the interior or the receptacle.

The manner of operating "the'atoirii'zer i's not apparent from its outward appearance. Consequently, tamperers willbe unsuccessful in "their first attempts to use the atomizer and will make no further attempt in the great majority of cases.

Although a specific embodiment of the invention'hasbeen illustrated and described, it will be understood that any alterations in the details of construction 'may be made without departing from the scope of the invention as indicated by the following claims.
