9 Claims. (Cl. 12S-192) v.

around the strands I8 of the electric cord G.

Among the objects of my improvement is to provide a simple and inexpensive vaporizer characterized by unusual compactness and which though normally sealed liquid tight may be quickly opened for use and quickly resealed liquid tight after use. The sealing arrangement eliminates the necessity of emptying the vaporizer or standing it up after the medicament it contains has been liquefied. This convenient feature permits the instrument to safely be packed in luggage containing clothing when travelling and prevents spilling the contents thereof at any time. This novel sealing means includes a nasal member which telescopes or folds into `the body of the instrument increasing compactness in packaging. My improvement also includes a special heating chamber in which the mixture of medicated vapors and air are superheated before they enter the nasal passage. The container for the medicament is easily removed from the instrument for cleaning, and the electric cord leading from the vaporizer to the lamp socket may be readily disconnected from the instrument to permit the instrument to be carried about whilst being used. This disconnect feature also serves as the electric switch of my improved vaporizer. Other novel features of my invention will appear in the following description and are illustrated in the accompanying drawing in which Figure 1 is a vertical section, double size, through my improved vaporizer showing the sealing parts in the closed position, and illustrating a permanent connection of the electric cord E to the base B;

Figure 2 is a view, double size, similar to Figure 1 showing the sealing parts of my improvement in the open position, and illustrating the detachable, switch type connection of the cord E to the base B, and

Figure 3 is a plan View, double size, of the constructions shown in Figures 1 and 2.

My improvement includes a cylindrical hollow cover or shell A threadingly or otherwise secured at its lower end to a base B into which is tightly pressed, or to which is molded, a vertically extending elongated heaterl tube C made of any suitable material such as aluminum. A looped resistance coil D is tightly packed in the tube and is insulated with respect thereto as by an asbestos covering I 4. Approximately midway its length the tube is reduced in diameter as at I5 and from this point down to the top I6 of the base B the tube preferably tapers slightly to facilitate removal therefrom of the container E which is U- shape in cross section into which the medicament to be vaporized is placed. To confine the major heating effect of the coil D to areas above the base B, I end the coil at approximately the bottom of the container E and, in the construction shown in Figure 1, I wrap the leads I1 of the coil 'Ihe cord projects through a housing I9 provided for it in the base B and is locked therein by suitable cement 20, or otherwise. The nasal member or nozzle` H ts closely in and slid-es in the upper end or neck 2l of the shell A and carries at its lower end a washer or gasket F which is cemented or otherwise strongly secured to this end of the nozzle. The gasket is made of suitable material and like the collar E is ring shaped and extends around the nozzleH an-d the heater tube C and fits tightly against the swelled or enlarged portion of the latter when in the sealing or closed position. At all times the gasket ts snugly against the inner walls of the cover or shell A. When the nozzle H is pushed vdownwardly in the shell or cover A against the open top of the contain'er E, as shown in Figure 1, the container is tightly sealed, and the annular opening shown at 22 in Figure 2 between the inner wall of the gasket and the heater tube C is closed by the liquid tight engagement of the gasket with the swelled portion of the heater tube as the nozzle is shoved down as aforesaid. At the same time the air vents 23 are closed liquid tight. The reverse of this movement of the nozzle unseals all these openings including, of course, the container E.

In the embodiment of my invention shown in Figure 2 the means for connecting the cord G to the base B includes a pair of terminals or pins 24 mounted in the end of the heater tube C. These pins project into the tube sufliciently to coniine the heating eil-ect of the coil D to the areas previously mentioned. The lead wires II of the coil are wrapped around, and suitably secured to these pins or terminals and the end of the tube is filled with a suitable hard cement to seal the tube liquid tight and insulate the coil and terminals with respect to the tube and to each other. The terminals extend a substantial -distance through the wall 25, which separates the lower end of the tube C and the opening 26 in the base J, to slidingly receive a conventional form ofv 'plug 21 molded to or otherwise secured to the cord G. With this arrangement current is admitted to the resistance coil D, heating it and the tube C, by pluggingthe cord G into the base J, and is denied the coil by removing the plug. This construction has the advantage of permitting my improved vaporizer to be carried about while being used without having to carry with it the electric cord G, and it eliminates the need of a switch to open or close the electric circuit.

In putting my invention into use, the shell A is unscrewed from its liquid tight connection to the bases B or J, and the medicament is placed in the container E. The shell is then replaced on the base, the nozzle or nasal member H drawn out to the open position shown in Figure 2, and current is admitted to the coil D either by using the switch at the lamp socket to which the cord is connected or by plugging the terminal 21 into the base J, or by doing both if using the embodiment of my improvement shown in Figure 2. This. admission of current lights the coil D, heating the container F and vaporizing the medicament. The vapors thus generate-d are, on inhalation, lifted out of the container up along the hot tube C through the hot air chamber 28 and into the nasal passage. The currents of air which enter the vents 23 and carry the vapors through this route, are quickly heated, especially as they travel along the hot tube C and move through the heated chamber 28 `and out of the opening 29 in the top of the nasal member or nozzle H.
