This invention relates to perfume dispensers, and more particularly to animproved perfume dispenser of the atomizer type adapted to be carried in a handbag, vanity case or pocket.

'A rnain object of the invention is to provide a. novel land improved perfume atomizer which is very 'simple in construction, easy to use, compact in 'size, and 'which maybe readily carried in a pocket, handbag, vanity case, and the like, without leakage orevaporation o 'f the perfume from the latomizer;l f t l further object ofthe invention is to'provide an improved perfume "atomizer comprisingA ya small number of simple parts which `are inexpensive to manufacture and easy to assemble.

Further objects and advantages of the inven'- tion will become' apparent from the following description and claims, and from the accompanying drawings, wherein: vl'igure 1 is an elevationalview ofa perfume atomizer constructed in accordancey with the.

Secured to plunger member i3 by a Screw member I4 and a bearing washer i5 is a deformable sealing washer It of rubber, leather, or other suitable yielding material, which is in slidable but sealing engagement with the inside Wall surface of barrel member I I. A coil spring I1 bears between washer I 5 and an annular seat I8 formed therefoiin'bottom cap member I2 to bias plunger member 53 upwardly with respect to the bottom cap member. Screw'member Id is formed with anaxial bore I9 for a purpose presently to be described.

Plunger member I3 is reduced in outer diameter with respect to its lower end portion t'o dene an annular shoulder 2l). Shoulder 2G cooperates with an annular rib 2| formed inside barrel I I adjacent its top end to limit extension of plunger member i3' upwardly with respect tobarrel I`I resulting from the free expansion of spring I'l, as shown in Figure 3. f

yPlunger member I3 is formed with an internal cavity having v a conical` bottom surface 22. Secured within this cavity by press-fitting o'r other suitable rigid securing means is a reservoir member 23 having an externally threaded upper end portion '24. The bottom surface 25 of the reservoir member is fiat except for a substantial Ioevel` The side surface of said reservoir is cylindrical and reduced in diameter with respect to the adjacent inner surface 'of plunger member lSto dene'an air passage'l. Itv will be noted that the `bevelr 2t is so oriented with respect vto conical surface 22 as to'provide an annular re'- strictedv passagesiinilar in effect t'o a Venturi orifice betwen the Vcenter portion of surface 22 and the peripheral portion thereof.

Secured in the upper portion of the wall of plunger member I3 is a nozzle element 28, shown in elevational view in Figure 2 and inf'crosssectional view in Figures 4'and` 5. Aligned with the orice in nozzle element' 28is an4 orifice 29 formed in the wallof reservoir member`23l A recess 30 formed in the upper shoulderedportion of reservoir member 23 provides A'communieation -between air space 'Zl'and the space intervening between orifice 29 and nozzle element 28.

Positioned inside reservoir 23"`and in engage;- rnent with itsinner wall surfaceis a diffuser sleeve 3|. Said. diffuser sleeve is formed with a' diamond-knurled exterior surface 32 to retard the passage of perfume liquid from the reservoir upwardly along the inne-r lwall surface of thel reservoir 4to orifice 29.' The bottom of the reservoir is conical, as shown at 33, and a pair of semicircular notches 34 -arejformedin theibottom edge -Wardly on top cap 35. lower portion of barrel passes through bore-I9 of the plunger screw I4 of sleeve 3| to allow the fluid to flow freely under said bottom edge. The lower end portion of the outer surface of sleeve 3| is slightly reduced in diameter, as shown at in Figure 8 to further promote flow of the perfume fluid to the diffusing surface of the sleeve. Said diffusing surface is normally covered with a film of perfume liquid, and the atomizing action consists in drawing perfume liquid from this film out through nozzle 28 in the form of a fine spray or mist. When the atomizer is not in use, the flow-retarding action of the roughened outer surface of the sleeve 3| prevents leakage of the fluid from the atomizer.

Threadedly engaged with threaded portion 24 of reservoir member 23 is a top closure cap 36. A sealing gasket 3'| is interposed between closure cap 36 and the rim of reservoir 23.

The top rim portion of barrel member II is formed with a flange having an annular in- Wardly directed rib 38. Rib 38 defines with annular rib 2| an annular groove 38. Nozzle member 28 is provided with an outer head portionl or fiange 40, shown most clearly in Figure 5, which is received in groove 33 to lock plunger ymember I3 in retracted position in barrel when the atomizer is not in use. A rectangular notch 4| is formed in rib 38 to permit head portion Alito be disengaged from groove 39 when the atomizer is to be used to spray perfume.

' When the atomizer is not in use the parts are in the position shown in Figures 1 and 2, with lplunger'member I3 retracted in barrel II against the pressure of spring I'l and locked by the engagement of nozzle head in groove 33. To use the atomizer, cap 36 is grasped and is rotated with respect to the barrel II until nozzle head 4I! registers with rectangular notch 4I, permitting the plunger member I3 to be extended by the expansion of spring Il. The operator then places his thumb over the bottom opening of bore 4 3 in the bottom cap I2 and presses down- The air trapped in the II is compressed and into. the central space below the fiat bottom surface 25 of Athe reservoir. The compressed air then passes radially through the annular Venturi-like restriction defined between the lower circular edge of the reservoir bottom surface 25 Iand the `conical surface 22 with a subsequent throttling action and is greatly accelerated. The air leaving the Venturi portion passes through :the air space 2`|v and out through nozzle 28. :Qinpe 'the rapidly moving air in the space be tween nozzle 28 and orifice 29 provides a low pressure or suction effect, liquid is drawn from the diamond-knurled surface of sleeve 3| through the orifice 29 and is combined with the low pressure air stream to produce a fine spray or mist emerging from nozzle 23, consisting Aof a mixture of air and particles of perfume fluid.

Thefuse of the annularVenturi structure defined by`- bevel -26 and conical surface 22 effects such a substantial building up of air velocity at nozzle 28 that the diamond linurled sleeve 3| may be relatively close-,fitting with respect to lthe inside surface ofthe reservoir 3| without .causing a breakin the continuity of the liquid -lm on the diamond knu'rledvsurface during the atomizing action. By the use of a close-fitting sleeve in the reservoir, leakage of the liquid from the `,atomizer when it is not in use is substantially eliminated. The atomizer may thus be carried many :position in a pocket or handbag without A danger of leaking, and the contents of the reservoir will not evaporate therefrom even when the atomizer is not used for long periods of time.

On the release stroke, the operator uncovers the bottom opening of bore 43 and allow spring I`| to expand, causing plunger I3 to move to its extended position. During this process air enters reservoir 23 through' orifice 29 and flows into the upper portion of the reservoir past the upper portion of knurled sleeve 3| to restore the pressure in the upper portion of the reservoir to atmospheric.
