Referring first in general to the embodiment of the invention illustrated in Figs. l through 11, the improved bottle top atomizer comprises a bottle adaptor 10, preferably molded of a synthetic plastic, into the upper end of which is press-fitted a tubular metallic shield or cylindrical sleeve member 12. The shield or sleeve member` 12 is provided'with a circular side opening 14 for passage of the atomized iluid and has telescopically fitted in its upper end for reciprocal and relatively rotative motion, a metal cylindrical pump sleeve or shell plunger 16. The upper end of the pump sleeve 16 is topped with a cap 18 adapted to be pumped by thumb against the action of an interior spring 20 and cause, in the manner hereinbelow to be described, atomized fluid to be discharged from the side opening 14 in the shield 12. The bottle adaptor member 10 may be provided with an internally threaded opening 22 at its underside adapting it for screw-on attachment to a bottle B the contents of which are to be atomized.

Considering now the construction and operation of the improved bottle top atomizer in greater detail, the bottle adaptor member 10 (see Fig. 9) which preferably has its outer periphery iluted as indicated by the numeral 24, is provided with a cylindrical recess 26 in its upper surface within which the shield 12 is press-fitted. A raised, circular central portion 28 is also provided in the adaptor member 10, which raised portion has a small center bore 30, a small off-center bore 32 and a pair of

circular recesses

34, 36, ninety degrees mutually displaced. The

bores

30 and 32 have respective, radially-extending

grooves

38, 40 communicating with the annular groove defined by the outer periphery of the central portion 2S and the circular wall of the cylindrical recess 26. A small metallic tube 42 is itted within the center bore 30 to provide a nipple on which is attached a flexible synthetic plastic tube 44 extending to the bottom of the bottle being used.

Press-fitted between the inner surface of the shield 12 and the outer cylindrical periphery of the central portion 28 of the adaptor member 10 is an annular flange or skirt portion 46 of a core member 48. Said core member has a flat undersurface portion 5i) from which extends a pair of locating pins 52, S4 tting into the

recesses

34, 36 respectively of the adaptor member 10. A vertical bore 56 extends through the core member 48 to communicate with the radialgroove 40 (see Fig. 2) and a Vertical bore 58 extends through the core member 48 to communicate with the radial groove 38 (see Fig. 7). The core member 48 has a iirst annular axial portion of reduced diameter 60 forming a first annular shoulder 62 and a second annular axial portion of further reduced diameter 64 forming a second annular shoulder 66 (see Fig. 2). The outer periphery of the second annular portion of the core member 48 is vertically flattened at a position aligned with the bore 58 as indicated by the reference-numeral 68 to provide an air passage for the purpose hereinbelow described. Said second annular portion has a longitudinal rectangular projection 71 at a position diametrically opposite said flattened portion to provide a locating key for parts hereinbelow described.

The core member 48 is horizontally bored at 72 at a position in alignment with the vertical bore 56 (see Fig. 2), to provide an opening from the annular shoulder portion 66 to the interior of 'the core member. A cylindrical plug member 74 is seated within the central opening of the core member 48. Said plug member is provided With an interior right angular channel 76 communieating at one end with the bore 72 and covered at the other end by a resilient ap 78 secured at one end in a groove in the plug member 74 and serving as a cheek valve.

Sealing or valve means is provided for shutting off the vertical bores 56 and 58 in the core member 48, the same comprising an annular valve assembly 80 of a metallic seal ring 82 (see Fig. 10), within the framework of which a rubber nail 84 is fitted. The real ring 82 is annular in shape and has a peripheral, substantially cylindrical, outer wall 86 and bent over, opposed, arcuate outer

top portions

88, 90 joined at their ends with inner arcuate

top portions

92, 94 by interconnecti ing portion 96, 98. The interconnecting portion 96 is inwardly stepped in the vertical direction and centrally drilled to provide an opening 100. The interconnecting portion 98 is inwardly stepped in the horizontal direction to provide a rectangular slot 102. The bottom of the seal ring 82 is open to allow fitting therein of the rubber seal member 84, said seal being of such shape and configuration as to iit within the seal ring 82 so that its upper and lower surfaces are substantially flush with the upper and lower ends of the seal ring (see Figs. 4 and The seal member 84 is further provided with a vertical opening 104 aligned with the opening 100 in the seal ring 82, and a vertical opening 106 ninety degrees displaced from the opening 104. The sealing means or valve assembly 80 is seated in the annular groove formed by the annular shoulder 62 in the core member 48 and is rotatable therein from the pumping position to sealing position in the manner hereinbelow more fully described.

Seated upon the annular shoulder 66 of the core member 48 and overlying the seal ring 82 and its contained rubber seal 84, is a metallic air washer 108 (Fig. 4) having an inner rectangular recess 110 by which it is keyed to the rectangular projection of the core member 48. At a position opposite the recess 110, the top of said washer has a horizontally stepped portion of reduced thickness 112 in the central portion of which there is provided a vertically apertured, upwardly-extending atomizing nozzle 114. The underside of the washer 108 beneath said nozzle is conically recessed, as indicated by the numeral '6, to reduce frictional force with respect to the iiow of fluid through the atomizing nozzle. At a position approximately ninety degrees removed from the atomizing nozzle 114, the outer edge of the air washer 108 is provided with an arcuate recess i 118 for the purpose hereinbelow described.

Surrounding the core member 48 and seated upon the air Washer 108 is an annular body member 120, preferably o-f plastic material, having an interior vertical slot 122 adapted to key said body member on the projection 71 thereof. The body member 120 is also provided in its outer surface with a vertical guide slot 124 terminating in a sidewardly-extending portion of increased Width 126 (see Fig. 6). At a position approximately ninety degrees removed from the vertical slot 124 in the body member 120, the bottom surface is provided with a shallow, inwardly-extending, substantially rectangular recess 128 (see Fig. 7).

An annular metallic purnp cap 130 surmounted by a rubber pump member 132 is fittedV upon. the upper end of the core member 48 and rests upon the body member 120. 4As indicated by the numeral 134 in Fig. 7, the longitudinal projection 71 of the core member 48 terminates short of the upper end of said core member so 4 that the metallic pump cap is not keyed to the core member. The parts mounted upon the core member 48 are held in assembled relation by turning over the upper end of said core member as indicated at 49.

The pump sleeve 16 reciprocally mounted within the shield 12 as hereinabove mentioned, is hermetically sealed with respect to the cap 18 by means of an intermediate gasket 136. The lower end of the pump sleeve 16 is inwardly shaped in the form of a lug 138 which in the assembled atomizer is located in the vertical slot 124 of the body member 120, thereby being constrained to vertical motion in said slot, and sideward motion only the lower portion of increased width 126 of said slot (see Fig. 2 and Fig. 6). At a position approximately ninety degrees removed from the lug 138, the pump sleeve 16 has a substantially semi-circular cutout portion (see Fig. 7), to allow for outward flow of .the atomized liquid when the atomizer is in pumping condition. v

As can best be seen in Fig. 2, the pump sleeve 16 is held in assembled relation with respect to the body member 120, by virtue of the fact that the pump member 132, after being assembled, blocks they upper end of the vertical guide slot 122.

With respect now to the operation of the improved bottle top atomizer hereinabove described, consideration will rst be given to the instance when the device is in open condition or ready for atomizing. Fig. 2 show's this condition with pump'sleeve 16 in the upward position, and Fig. 7 showsv the sleeve pressed in the downward position. When the pu'r'np sleeve 16 is pressed downwardly, air entrapped in the uppor portion of the device will be forced down the passage formed by the flattened portion 68 and out over the horizontally stepped portion of reduced thickness 112 of the air washer 108. In passing said stepped portion, the air will iiow with increased velocity over the atomizing nozzle 114, whereupon liquid from the bottle B will be drawn up through the tube 44, the nipple 42, the channel 38, the bore 58 in core member 48, the opening 106 in the rubber seal 82, and the nozzle 114, all of which are in communicative alignment when the device is in operating position.

It will be evident that on the downward stroke of the pump sleeve 16, air flow into the bottle is prevented by means of the check valve in the plug member 74. However, upon the return stroke of the pump sleeve 16 (in the upward direction). air can pass through the bore 32, channel 40, bore 56, aligned

openings

104 and 100 in the rubber seal 84 and the seal` ring 82, respectively, side opening 70 and vertical opening 76, past the check valve ap 78 and into the upper portion of the pump sleeve 16. It is further to be noted that this air passage for the return stroke is of such size as will offer less resistance to air passage than the above-described path past the nozzle 114, so that the possibility of liquid being aspirated inwardly during the return stroke will be minimized.

When it is desired to close the bottle top atomizer, it is only necessary to turn the pump sleeve 16 slightly when inv the downward position so that its bottom lug 138 becomes latched in the sidewardly-extending portion 126 of the guide slot 124 (see Fig. 8). In turning the lug 138, extending through the arcuate recess 118 in the air washer 108, carries with it the seal ring 82 together ,with its rubber seal 84, since the lug 138 will also extend when in this lowermost position, into the rectangular slot 102 in said seal ring. The resulting rotary movement of the rubber seal 84, will therefore seal off at the annular shoulder 62 of the body member 48, the above- -described passages communicating with the

vertical bores

30 and 32 leading to the interior of the bottle B. The 'semi-circular cut-out 140 in the pump sleeve 16 moreover, will be moved out of alignment with respect to the opening 14 in the outer shield 12 to close olf the chamber surrounding the nozzle 114 from the outside.

The modification of the invention shown in Fig. 12, diiers only from that described above in connection with Figs. 1 through ll, in that the bottle adaptor 142 has an externally threaded portion 144, upon which a cylindrical container 146, enclosing the small bottle 14S is screwed. There is thus provided a small, neat atomizing device suitable for carrying in a pocket or handbag.

Figs. 13 through 17 illustrate an alternative embodiment of the invention, wherein a modilied form of seal ring is used. In Fig. 18, the seal ring 150, shown in upside down position for clarity of detail, comprises an annular metallic ring having an outwardly-struck pair of

lugs

152, 154 comprising at

portions

156, 158 spaced from and parallel with respect to the Ibody of the seal ring and

outwardlyextending portions

160, 162 bent at right angles to said flat portions. A substantially square hole 164 is provided in the seal ring 150 between the

lugs

152, 154. An arcuate rubber seal 166 (Fig. 17) has a central, substantially square projection 16S adapted to tit into the square hole 164 in the seal ring 150 when the end portions of the seal 166 are seated against the lugs 152, 154 (see Fig. 14). A vertical opening 170 extends through the seal 166 centrally of its square projection 168. The ends of the seal 166 extend just short of ninety circular degrees from the central opening 170. Another lug 172 is struck from the seal ring 150 at a position substantially opposite the square hole 164, said lug having a portion 174 bent parallel to the body of the seal ring at such spacing thereupon as to be substantially in a plane with the outer surface of the rubber seal 166 when in place. At a position approximately midway between the square hole 164 and the lug 172 in the seal ring 150, said ring is provided with a substantially rectangular recess 176 adapted to receive the lug 138 in the pump sleeve 16 to turn the ring together with its rubber seal 166 when the device is turned to locking position as described above in connection with` the tirst embodiment of the invention illustrated in Figs. 1 through ll. Operation 'of the modifier device is the same as described in co-nnection with the embodiment illustrated in Figs. l through l2. It is to be noted in this connection that the length of the seal 166 is such that it will seal ott the vertical bore 56 in the core member 48 when the device is in locked condition.

While there has lbeen disclosed in this speciication three forms in which the invention may be embodied in practise, it is to be understood that these forms are shown for the purpose of illustration only, and that the invention is not to be limited to other specific dis-closure, but may be modied and embodied in various forms without departing from its spirit. In short, the invention contains all the modifications and embodiments coming within the scope of the following claims.
