1 Claim. (01. 128- 498) This invention relates to new and useful im-' provements in inhalers and particularly of the type using a medicated filler or a crystallizedor granular substance adapted to produce vapors or 6 fumes for inhalation in the treatment of nose channel capacitated for receiving a suitable seal- 6 and throat ailments. ing washer or gasket l6.

The lower end of the container shell I0 is formed outwardly with an integral supporting flange l4 terminating in an upstanding circumferential wall l5, thus providing an annular lating the same, and thus assure a hermetical seal between the parts It] and 20.

In order to facilitate the manipulation of the cover member 20, the upper end of said cover to is formed with arelatively narrow expanded secsubstances in this inhaler, in which case the outlet opening l3 in the end of the container shell ID will be closed and provided with a number or smaller openings, and also the intake openings at the opposite end will necessarily be made smaller and of a size to preclude the escape, of the crystal or granular substances therethrough.

In practice, after the container shell Ill has been chargedor filled with the desired inhalant,

it is used by applying the conoidalend l2 to the nostrils and inhaling. This causes a flow of air to enter the inlet ports l9, pass through the annular space X surrounding the filler H or through the interstices of granular and crystal substances when the latter is used, and become saturated or charged with the fumes or vapors in its passage to the outlet port,l3. After the inhaler has been used, the cap 20 is slipped or telescoped over the shell l0 until the adjacent convolutions of the, threads 20 and 22 of shell l0 and cover 20 respectively contact each other after which one or two turns of the cover 20 will interlock and hermetically seal the parts. It will be apparent that while there areoemployed certain details of construction for the purpose of adequately disclosing the invention, vart ious changes or modifications of the construction herein shown and described, may be made within the scope of the appended claim without departing from the spirit of this invention or sacrificing its advantages.

What is claimed is:

In an inhalant device, a drawn metal container shell having one end formed with a tapering nozzle portion and the opposite end open for receiving an inhalant material therein, the apex of said nozzle end having a discharge aperture, a flange extending outwardly from the open end of said shell and having an upstanding peripheral w'all defining an annular channel, a sealing gasket disposed within said channel, a closure cap covering the open end of shell and formed about the free end of said wall and adapted to embrace a portion of said gasket to retain the latter in place, said shell having ingress means adjacent said washer, and a cover means having detachdiate portion of said shell and engaging said gas ket for hermetically sealing said device.
