ATOMIZER Filed Feb. 15, 1943 INVENTORS Jo 5. Schm/fl MW/am ff. Dodds ATTORNEY Patented Sept. 12, 1944 OFFICE ATOMIZER v Joy B. Schmitt and William R. Dodds, Toledo,

Ohio, assignorsto The -De Vilbiss Company, 7 Toledo, 0hio,.a. corporation of Ohio Application February 15, 1943, Serial No.47ao14 4} Claims;

This invention relates toatomizers designed particularly for the application of medicinal'prep arations but which are suitable for applying other Still another object of our invention is to provide an atomizer in-which the liquid preparation flows through the bottom of the container to the discharge tube, and one so constructed that no liquid will leak from the nozzle when the atomizer is in its ordinary upright position.

Other important objects of our invention will be apparent from a reading of the following description in connection with the drawing wherein, for purposes of illustration, we have shown a preferred embodiment of our invention.

In the drawing Fig. 1 is a side elevation of the embodiment;

Fig. 2 is alongitudinal sectional View taken through Fig. 1;

Fig. 3 is a section of the atomizer nozzle taken on a line '33 of Fig. 2; and

Fig. 4 is a section of the air and liquid tubes taken on a line 4-4 of Fig.2.

Referring in detail to the drawing, the atomizer has a main body portion I which has an upper cuplike cavity 2 for holding the medicine This is closed by cap piece 3. Integral with the body is a conical supporting apron 4 upon which the atomizer rests. Through the body portion! is an inclined passage 5. Into this from one side is inserted air nipple 5, to the outer end of which.

is :fastened air bulb 1. At the rear of the air bulb I is an air check valve 8 of conventional design,

permitting the entrance of air into the bulb when the bulb expands and preventing a flow of air out through the valve on compression of the bulb.

In the front end of nipple B is pressed a long air tube 9.

To the same 'end of the nipple 6 extending through the body I is threaded a liquid tube at in Fig. 3, providing three grooves for the fluid to pass through foo reach the nozzle discharge opening I l at the end of tube ID. V

After the proper amount of the medicinal prep arations has been introduced into the receptae cle portion 2 by dropper or other means,.the cover 3 may be putin place to prevent spilling. This cover 3 should either fit loosely enough to provide a slight space for air toenter the cup or should have a small vertical groove in the skirt portion' to act. as a vent passage. 'If it. follows the natural flow induced by gravity, at least some o f the medicament will pass down from thev cup through the port [2 to angular groove 13 in the air nipplei From this groove [3 two opposed passages l4 extend to, thev longitudinal passage I5. From here'the medicine will flow up toward the discharge opening ll through the extension of passage 15 to a point within tube [0 where it is level with the surface of the medicinal preparation remaining in cup 2. p

The tube II] is so inclined upwardly that its top point is level with the top of cup 2. This prevents the liquid from flowing out of tip ll when the atomizer is in its normal upright position. When it is desired to use the atomizer, the tip is inserted into the mouth or nasal cavity,

of air and liquid occurring at port ll results in the atomization of the liquid.

The general desi n of the atomizer makes it compact. The bottom outlet of the receptacle permits the drainage of all medicine therefrom. This is not possible from the ordinar atomizer which has an outlet tube extending down into its receptacle. Some medicine is ordinarily left beneath the end of such outlet tubes.

The one piece body portion is inexpensive to manufacture and provides a fine supportin base for the bulb on one side and the discharge tube on the other without any threaded engagement directly with either of them.

The bulb and air'assembly by threaded engagement with the tube I0 is held against body portion .I. Nipple 5 fits tightly into the body, thereby preventing any leak of the liquid.

Although we have shown and described herein a preferred embodiment of our invention,,it is'definitely to be understood that we donot desire to limit the application of the invention thereto, and various changes may be made in the structure and arrangement of parts without departing from the spirit of our invention and avoiding the scope of the following claims.

We claim c j 1. In an atomizer for applying a single dose ofmedicine orthe like, a body piece having a cuplike cavity at its top and a similar inverted cavity at its bottom,- the upper cup forming a receptacle for the medicine and the bottom edge of the bottom cup forming the supporting base for the atomizer, an inclined passage through the center of the body portion between the cups, a

nippleextending through the passage from its, lower end, an air bulb fastened to the outer end therewith for the preparation, "an upwardly inclined bore through the body, a ertical passage into the bore communicating withthe receptacle,

an outwardly facing shoulder at each end of the bore, an air supply nipple extending into the bore from its lower end and seating against the'shoul-' tr'ally into and through thellquid dischargetube to carryair to the discharge end of said tube.

3. An atomizer for spraying medicinal preparations and the like, comprising a body, a recep tacle of restricted size in the upperportion of the body with an outlet in itsbottom, an elongated nozzle haying communication with the receptacle outlet and extending in a straight line from the body below the receptacle to a point above the normallevel of the liquid inthe receptacle, a flaring supporting base integral with Q the body and an air supply bulb fastened to the body on the opposite side of, but in line with the elongated discharge nozzle and having communication with the nozzle to supply it with atoniiz ing air. L

4. In a medicinal atomizer of the type described, a body, a receptacle for medicine attached to the body, a transverse bore through the body, an outwardly facing shoulder at each end of the bore, an airsupplynipple seating against der at that end, an elongated liquid discharge 7 tube extending from the opposite end of. the bore and held against the shoulder at that end through a connection'with the air supply nipple, a passage in the air supply nipple for delivering the preparation to the liquid discharge tube and an extension of the air, supply nipple extending cenone of the shoulders, an elongated discharge nozzle held against the other shoulderby'a connection through the bore with the air supply nipple, an elongated air tube fastened to thenipple andextending therefrom through the bore and centrally intoand toward the outer end of the discharge nozzle, a passage between the receptacle and the bore to deliver medicineto the nozzle, and an air bulb connected to the nipple for supplying atomizing air through the air tube to the nozzle.
