PERFUME ATOMIZER Albert Christen, Geneva, Switzerland, assigner to E. C. I. Handels und Industrie Anstalt Etablissement du Commerce et de llndustrie, Vaduz, Liechtenstein, a corporation of Liechtenstein Application November 3, 1949, Serial Nc. 125,337 In Switzerland November 15, 1948 A large number of types of atomizers or scent sprays have already been proposed for atomizing perfumes and scents and they are generally satisfactory when they are used daily, but their operation becomes faulty when by reason of a protracted duration cf nonuse, dry perfume drops clog the suction tube provided for the perfume entering the container of the atomizer or again the tube feeding air to said container.

Such atomizers include generally a perfume container into which opens a pipe for feeding into it the air that is to take the place of the atomized perfume and a perfume delivery tube through which said perfume is sucked by a jet of air produced when a hand controlled pump is actuated, the piston of which'is submitted to the action of a spring and slides inside a cylinder.

Now my invention has for its object an atomizer of the type disclosed that is capable of removing the above mentioned drawback by reason of the fact that it includes means for closing the tubes through which the air is admitted and the perfume is delivered.

I have illustrated diagrammatically in accompanying drawing by way of example two preferred embodiments of my improved atomizer. In said drawings:

Fig. 1 is an outer view of my improved atomizer or scent spray.

Fig. 2 is a part sectional view through the plane containing the axis of the piston and that bodiment of a scent spray according to my invention.

In accompanying drawing only those members and parts necessary for a. proper understanding of the invention have been illustrated in order to avoid an unnecessary overloading of the drawing.

The atomizer or scent spray illustrated in Figs. l, 2 and 3 includes as in the case of other atomizers a casing l provided with an inner container 2 for the scent and a pump including a cylinder 3 inside which slides a piston that is not illustrated and that is submitted to the action of a spring and is controlled by hand operated member 4. The cylinder 3 and the container 2 are carried by a common support 5 provided with an air delivery channel E connecting the cylinder chamber 3 with a nozzle 'l' on the outside of the support 5 while two further channels 8 and 9 open inside the container 2.

The channel 5 2 Claims. (Cl. NS2-38) is adapted to provide for the entrance of air inside the container 2 while the scent is being sucked through the chanel 9 and lower tubular extension thereof by reason of the pressure exerted by the air jet passing out of the nozzle l. The casing I is provided with an opening or gate 22 registering with output end of the nozzle 1.

As illustrated, the atomizer or scent spray according to the invention is provided with means for closing the channels 3 and 9 that are submitted to an elastic action for holding said channels normally closed. These closing means are constituted in the embodiment illustrated by way of example by two closing members I2 and I3 carried by an actuating member, in the case illustrated a lever lil pivotally mounted on a spindle II, rigid with the support member t. Each closing member l2, I3 carries a needle valve I4 and a washer I5 of yielding and elastic material. The member l2 cooperates with an air inlet nozzle 25 asscciated with the channel 8 while the member I3 cooperates with a nozzle d associated with the scent vchannel 9.

The lever Ill carries at one end a semi-circularly recessed part provided with two studs I6 engaging freely a groove I'I provided in the control member lvsubmitted to the action of a spring I9 and sliding over a guide member 23 rigid with the carrier 5. The lever I carries furthermore a shutter member 2l adapted to close the gate 22 in the casing wall referred to hereinabove.

The operation of the atomizer described is as follows:

In its inoperative position illustrated in the drawing, the spring I9 projects the control member I8 through the wall of casing I whereby the needle valves I4 are held by the lever Ill] inside thev bores provided in the corresponding nozzles 25, 25 and furthermore the packings or washers I5 are urged against the ends of said nozzles. Thus the channels 8 and 9 are completely sealed and the possible losses of the scent contained in the container 2 through evaporation are neglisible. y

After disengagement of the two parts of ya bolt of which only the part 23 is illustrated, and that holds the hand operated control member 4 into its collapsed position against the action of its spring, the operator should set his or lier forefinger on the control member I3 and his or her thumb on the now released member 4 after which the operator exerts a double thrust in antagonism with the action of the spring I9 and with that of the spring returning the pump piston back.

Inspection of accompanying drawings shows that such a, thrust produces The rocking of the lever I through an axial shifting of the pusher member I8 and thereby a release of the needle valves I It that move away from the corresponding nozzles and also an uncovering of the gate or opening 22.

The actuation of ithe pump piston in antagonism with its spring so as to produce the delivery of a stream of air through the nozzle 'I and thereby a suction of the scent through the channel 9, which provides the atomization and projection of the scent through the gate 22 of the casing.

When the operator releases the control members 4 and I8, the spring I 9 produces the reengagement of the needle valves inside Ithe corresponding nozzles while the return spring of the pump moves the member 4 back into its starting position as illustrated in Fig. 1.

Thus through each actuation of the pump the operator produces automatically the opening of the channels 8 :and 9, while their closingY is obtained automatically by `the spring I9 as soon as the operator releases fthe member 4 controlling the atomizer pump. The succession of such engagements and releases of the needle f valves inside the corresponding nozzles produces an automatic cleaning of said nozzles whereby if for any unforeseeable reason whatever a dried drop of scent were to close one of said nozzles, a further actuation of the atomizer provides au tomatically for their cleaning Iand restores consequently the atomizer into its prior operative conditions.

In the embodiment illustrated in Fig. 4, the lever I' pivotally secured at Il to the common support is submitted directly to the action of a spring 30 bearing against said support 5. The member controlling said lever is constituted by an auxiliary piston 3| slidably carried in a recess provided in the support 5 and opening into the air-delivery channel 6.

The closing members I2 and I3 are similar to those described with reference to Figs. 2 and 3; however they are provided with needle valves 32, the length of which is suicient for them 4to remain always engaged inside the corresponding nozzles 25 and 2t while in contra-distinction, their diameters are clearly smaller than the diameter of the channels bored in said nozzles 2S and 25.

Furthermore, the channels 8 and 9 are rectilinear so as to avoid as far as possible any settling of scent drops therein.

The operation of this atomizer is similar to that of the atomizer described with reference to Figs. 1, 2, 3; however the actuation of the lever i0 in opposition to its return spring 30 is performed through the auxiliary piston 3I that is submitted to the air pressure prevailing in Ithe channel 6 when the atomizer pump is being operated. This provides consequently an entirely automatic actuation of the lever I0. As described hereinabove, and as illustrated in Fig. 4, the needle valves 32 remain always in engagement with the inside of the nozzles 25 and 26. The length of said needle valves is suiicient for them to pass throughout the channels 8 and 9 and to enter the actual scent container when the said channels 8 and 9 are closed, as illustrated in full lines. Thus when the lever I0 is actuated the movements of said needle valves produce a cleaning of the channels 8 and 9 throughout their length. To allow the suction of scent through the nozzle 26, the diameter of the bore through the latter should be larger than that of the needle valve 32 passing through it. Furthermore in order to prevent said needle valve from forming too considerable a hindrance in the path of Ithe air jet passing out of the nozzle 1, said needle valve is provided with a at part 33 located immediately above the nozzle 26 when the closing member is raised and inoperative. This flat part 33 does not form then an objectionable hindrance for the jet of air passing out of the nozzle 1. Obviously said ilat part 33 should have a breadth that is not greater than the bore in the nozzle 25. Furthermore, the needle valves are secured to the lever I0 through the agency of the sealing members I5 made of yielding and elastic material whereby said needle valves do not risk by any means becoming wedged inside the nozzles through a possible angular movement of the lever I0.

From the preceding disclosure and from inspection of accompanying drawing, it is readily apparent that the atomizer or scent spray disclosed has considerable advantages over the conventional arrangements of similar type. Obviously the two embodiments described by way of example hereinabove may be modified in their structural details without unduly modifying thereby the scope of the invention as defined inv accompanying claims.
