(ci. 12s-200) l 2 This invention relates to inhalers and partic ularly to the type which 'is adapted to be molded charge or outlet opening for the medicated vapor throughout of suitable synthetic plastic material. threaded enlargement I3 is provided at the lower accumulating in the casing. An internally end of the cap for the reception of the corre The invention contemplates the provision of a spondingly externally threaded upper end I4 of simple inhaler provided with a valve at each end the casing part II. `To prevent leakage of vapor and adapted to be easily manipulated, without between the parts, a washer or gasket I5 of any removing any of the parts, to open both valves suitable compressible material such as cork, rub simultaneously and thereby to establish com ber, felt or the like is seated on the interior munication between the interior` of the inhaler 10 shoulder I6 of the enlargement I3. At the lower and the outside air. end of thepart Il is made an axial ,opening The invention further contemplates the provi which is preferably the inlet opening-for outside sion of a- holder for medicament slidable in the air into the casing. Said opening has an en interior of the inhaler and provided with opposed larged outer portion I'I and a constricted inner valves, one of which projects beyond the inhaler l y casing in the operative or open position thereof, 15 portion I8 for the purposes soon to appear. Slidably mounted in the interior of the casing and the other of which so projects in the in is the medicament holder I9. ` Said holder is also operative or closed position thereof, the pro adapted to be molded of synthetic plastic and is jecting valves forming the means by which the in the general shape of an elongated O, being holder may be manipulated. The invention further contemplates the pro 20 provided with the teat-like axially arranged op posed and projecting valve stems 2D and 2 I. ` The vision of an inhaler having only three separable medicament is inserted into or removed from the and moldable parts comprising a two-part casing central space 22 of the holder when the cap I0 is and a holder for medicament together with co removed, and may be carried by any suitable operating valve parts thereon, and in which in haler the casing parts need be separated only 25 known device intended for lthat purpose such as the elongated cartridge 23 (Fig. 3) or a wad of when the medicament therein is to be renewed, absorbent cotton. . ` ' the inhaler being otherwise operable without such The upper valve stem 20 is preferably tapered separation. and molded integrally with the top of the holder The invention further contemplates the provi and has an annular recess Vor indent in the lower sion of an inhaler adapted to be opened for use part thereof filled by a hollow resilient washer and closed by one hand oi the user. or gasket 24 of rubber, cork, felt or the like ar The various objects of the invention will be ranged to enter thevdischarge port or opening clear from the description which follows and I2 and to be pressed into contact with the wall of from the drawing, in which said opening when the holder is in its uppermost Fig. 1 is a vertical section of the inhaler taken or valve port closing position to prevent leakage on the line I--I of Fig. 2, showing the inhaler in of vapor. ' ' . its closed or sealed inoperative position. The lower valve stem 2I may be detachably or Fig. 2 is a similar section taken on the line permanently secured as desired to thel lower end 2-2 of Fig. 1. Fig. 3 is a partial front elevation and partial 40 of the holder, but in Ithe form shown, it isscrewed thereto and terminates at itsv lower end in> an section'of the inhaler in its open or operative enlargement such as the head 25 adapted to fit position, showing the medicament in place in the holder therefor. - Fig. 4 is a horizontal section taken on the line 4-4 of Fig. 1. into the enlarged part I'I of the adjacentinlet opening. For adequately sealing the inlet openf .45, ing when the inhaler is not- in use, a hollow washer or gasket 2,6 in the form of a ilanged eye Fig. 5 is a foreshortened perspective view of the let is provided. The flange of the washer, 26 medicament holder, the middle part of the holder contacts with the top of the Wall surrounding the being broken away for convenience of illustra enlarged part I‘I of the inlet opening and the tion. In the embodiment of the invention shownby 50 cylindrical part of the washer engages the wall of the portion I8 of the opening when the holder Way of example, the inhaler casing consists of two preferably but not necessarily molded parts I0 and I I, the part llLbeing in the nature of a cap and having an axial opening I2 in the end there of, which opening is preferably used as a dis-~ 55 is in its port closing position. There, the »holder is at its uppermost limiting position’in the cas ing,vbut the lower party of the holdergis in Suffie . cient upward spaced relation to the bottomfoffthe 2,410,798 3 4 casing part H to carry the inlet valve stem into its closed position, (Figs. l and 2) and the upper end of the valve stem 2B projects a sub stantial distance outwardly beyond the casing for From the above, it will be seen that I have pro vided an inhaler having a slidable holder capable of easy manipulation with one hand without dis turbing the casing, .that the inhaler is adapted to be molded of plastic material and is provided with opposed valves accessible from the outside access thereto by a linger or the thumb of the user. To move the, holder into theopenor extreme lowermost position of Fig. 3, the user may gra-sp the >casing in one hand and need merelypress axially on the valve stem 20 with the thumb or finger of the same hand thereby sliding the holder downwardly and opening both valves simulta-" and operating simultaneously and effectively to permit and prevent the discharge of vapor as desired. l0 neously, the valve 2 I, 25 in this position projecting downwardly below the casing.V the userin the appended claims. -I claim: l.
