Specification of Letters l at'ent.

Patented Mar. as, 1922.

Application filed March 7, 1919. Serial No. 281,309.

To an whom it may concern:

. Be it known that I, FRANK .C. DORMENT,

a citizen of the United States, residing at Cleveland in the county of Cuyahoga and State of hio, have-invented a certain new and useful Improvement in an Inhaler, of which the following is a full, clear, and exact description.

This invention relates ito an inhaler, the purpose of the device being to contain a suitable medicament by which a'person may by inhalation treat the mucous membrane of the passagewaysof the throat,- nose and other head cavities. -The treatment of colds and van efiective inhalerto be produced at low costof manufacture. i

The present inhaler whileso constructed as to be of low cost does not sacrifice any essential features necessary for its proper function, but on the contrary it is one of the objects of the invention to provide an inhaler in which the medicament contained is held from leakage as well 'as from dissipation except when in useand additional regulation of the flow of air is provided.

Generally'speaking the invention may be said to comprise the elements and devices set forth in the accompanying claims. Bet.

erence should be had to the accompanying drawings forming a part of this specification in which Fig. l is an elevation in section showing the device of my 1nvent1on;. F1

V 2 is a" verticalflelevation with portions in section, showing the device in position for use; Fig. 3 is a section upon the line 33 of fieferring to the drawings 1 indicates a body which at its end'is given a conical cylindrical in shape.

. shape in Order to facilitate its introduction to the mouth or nose of the user. The body portion is hollow in part and is open ended. The conical shaped-head is provided with a passageway formed in two parts which parts are of different diameters the passageway 2 being of less diameter than of passageway The difference in the diameters of the passageways 2 and 3 provides a shoulder against which there lies a disk of packing material 4.

3 Within the hollow portion of the body and snugly fitting the wall there is a member 5 which is in the present instance substantially This member 5 ismade of a material which is absorbent such as compacted asbestos or material of stony nature, or any other material of such a nature that the medicament with which the member 5 is impregnated does not tend to become rancid. In place of the member 5 being made of an absorbent material which is adapted to be impregnated with a medicament, I am substituting a member of similar shape and form which is a solid body of the ill dicament, itself.

For instance menthol may be molded into a shape similar to that of the member 5 and inserted within the body 1, replacing the member 5. hen this is done, the body of menthol may be renewed as fast as a previous body becomes dissipated. here in the clauns I refer to"a medicament retaining means I wish to include both which have been described.

The lower open end of the body is closed by means of a closure member 6 which is provided with a central opening which opening is enlarged in a conical shape at its outof the features ward end as indicated at 7, Fig. 2.

Extending through the opening in the member 6 and into the space within the body is a member 8. This member at its outward endis provided with a disk 9 which serves as a handle or means by which the member 8 may be manipulated. The portion of the body 8 which is adjacent the disk 9 is flared outward in a conical shape as indicated at 10 and when the member 8 is moved to its mostinward position as indicated in Fig. 1,

the portion it) occupies the part 7 of the closure member 6, producing a wedging action which serves to make a tight fit so as to prevent the entrance oi air except when the member 8 is more or less withdrawn as indicated in Fig. 2.

The member 8 is provided with one or more longitudinally extending passageways such as indicated at 11 and it will be apparent when the member 8 is withdrawn to such an extent that the end of the passage-.

way 11 which is adjacent to handle 9 is exposed that the air may enter the passageway 11 and pass into the space within the body portion which is adjacent the absorbing element 5.

The adjustment of the member 8 with resp ct to the body portion controls a quantity of air which may pass through the body portion. Itwill be understood that when the member S is not in the position shown in Fig. 2, the inhaler is in position to be full open and the maximum quantity of air may be drawn. through it. \Vhen, however, member 8 is pushed into the body portion. so that the extension 8 and the upper part of the member 8 occupy in part the openings 2 and 3 in the body portion, these passageways are .-'-3stricted and further in accordance with the degree in. which the passageway 11 is open, the quantity oi: air passing through the inhaler may be regulated.

In order to limit the outward movement oi? member. 8, a cross pin 12 provided which extends through the member 8 and is adapted to engage with the closure member 6 when the member 8 is drawn outwardly.

One of the ends of the member 8 is provided with an extension 8 which is of less diameter than the member 8. This construction provides a shoulder such as indicated at 8". The size of the portion 8 is such as to snugly lit the opening 2 and likewise the size of the member 8 is such as to snugly lit the opening 3 and when the member 8 occupies the position shown in Fig. l, the shoulder 8 presses against the packing 4-. The construction which has just been described very eilectively, presents the exit of the volatile medicament with which the absorbent member 5 is impregnated at those times when the member 8 is in the position shown in Fig. 1 and as before described the flaring portion 10 of the member 8 engaging with closure member 6 prevents the entrance of air so that the device is an tight.

when the member 8 is in the position shown in Fig. 1.

This is an important characteristic of the present inhaler and permits the inhaler to be carried in the pocket of the user and furthermore, the medicament is not dissipated except at the time when member 8 is withdrawn for the purpose of using the inhaler. In introducing medicament to the inhaler,

the member 8 is withdrawn as indicated in Fig. 2 and the proper amount of medicament is introduced through the opening The medicament is promptly absorbed by the absorbing member 5, leavingno liquid within the interior of the receptacle.

The various elements making up the inhaler may be constructed of any material desired, but it is my purpose to construct the body portion 1 as well as the member 8, out of wood, or material of similar character, and to provide the surfaces of the wood with what is known as a rubberized finish. This finish is an enamel finish resembling hard rubber which is non-absorbing in its nature and will stand,'-without being affected, a temperature of 300 E, thus enabling the device to be sterilized which is of course a matter of importance in devices of this character.

The closure member 6 may be made of any desired material, but I have found that cork forms a very effective and desirable material and due to the factthat it has some resilience it enables a very tight fit'to be ob tained'in the body portion, and further enables the flaring part 10 of the member 8 to be snugly fitted in the portion 7 of the 010- sure member. 'The closure member 6 is held within the body'portion in any desired man ner.

Obviously-variations in the particulars of construction of the inhaler which have been described may be varied without departing from the spirit of the invention. 7

I claim p 1. An inhaler comprisinga body portion provided with a head, said head having an opening therethrough,-which opening is provided with a shoulder, said body portion being hollow, a closure element at the end of the bodyportion, said element being provided with an opening; a member extending through the'opcning in the closure element and having a close fit therein, said member being provided with a portion adapted to occupy the opening at the head of the body portion and have a close fit therewith, said member being provided with a shoulder which engages with the shoulder of the passageway formed in the head of the body portion; a medicament container within the;body portion and means associated with the aforesaid for permitting passage of air to'the interior of the body portion. 1

2. An inhaler having a body portion formed of wood-like material, said body portion having .a head and a passageway extending through said'head, the body being hollow in part, a coating of impervious'material' covering the exposed surfaces of the body portion, a closure element for said body portion, said closure element having an opening therethrough; a member extending through the opening of-the closure e1em'ent said member being formed of Woodlike material and provided with a coating of impervious material the said member having a portion adapted to extend into the opening formed in the head of the body portion; a medicament container within the body portion, and means controlled by the aforesaid member for admitting air to the body portion.

In testimony whereof, I hereunto afliX my signature.

FRANK o. DOR-MENT.
