7 Claims.

This invention relates to atomizers of the type intended more particularly for toilet and medicinal purposes, and has primarily for its object the provision in such an atomizer of a novel nonleak feature to enable packing and carrying of the atomizer in reclining or inverted position without leakage of its liquid contents, which feature utilizes the turning of the atomizer head on the receptacle to open or close the passages through which leakage of the receptacle contents might occur.

A further object of the invention is to provide a non-leak feature for atomizers, which is of such a simple and inexpensive nature as to enable low-priced atomizers to be provided therewith with little or no increase in manufacturing cost.

This invention is fully described in the following specification, and while in its broader as- 4 .pect it is capable of embodiment in numerous forms, one embodiment thereof is illustrated in the accompanying drawing, in which- Figure 1 is a side elevation of an atomizer embodying the invention; Fig. 2 is an enlarged fragmentary central vertical sectional View thereof, with the spray-head in closed relation to the receptacle, and Fig. 3 is a section on the line 3-3 of Fig. 2.

Referring to the drawing, I designates a receptacle of an atomizer of the type used for spraying perfumes or other toilet liquids, and 2 the spray-head unit mounted thereon.

The head mounting means, in the present instance, comprises a cap-like ferrule 3, which fits down over the receptacle neck 4, being cemented or otherwise suitably secured thereto, and having its top portion centrally formed with an outwardly extending nipple 5 forming an opening in communication with the receptacle interior 49 and being externally threaded for threading engagement within a socket of the head.

The head unit 2 includes a body 6 having a cylindrical socket l centrally in its bottom and of suitable size to receive and have threaded engagement with the nipple 5. The nipple is shorter than the depth of the socket 1, so that when one is screwed home within the other, a free space is left between the end of the nipple and socket bottom for the purpose hereinafter described.

The head body is provided with a spray nozzle 8 to which air and liquid passages 9 and II) respectively lead, as Well understood in the art. The air passage 9 has communication with the 5 compression bulb II or other suitable source of air pressure supply, and the liquid passage Ill leads to the nozzle chamber from the aforesaid free space at the bottom of the socket I.

The liquid discharge tube I2 of the head unit is fixedly carried at its upper end by the head 5 body and projects downwardly therefrom centrally from the bottom of the socket I through the nipple 5 and down into the receptacle I to near its bottom. The tube has an annular enlargement I3 which projects within the bottom 10 free space of the socket I and provides a tapered or conical face I 4 for seating against the end of the nipple 5 at its inner edge, which edge is preferably left sharp, as shown in Fig. 2. The tube I2 below the enlargement I3 preferably 15 slidingly fits the nipple bore and is provided in close proximity to said enlargement with a port I5, which, when the enlargement is unseated with respect to the nipple end, opens communication between the tube passage and 2n the head passage Iii through the said socket free space. It is thus apparent that when the valve formed by the tube I2 and nipple 511s open and a suction is created in the nozzle 8 by the discharge of air therethrough, such suction acts 25 through the passage I 0, socket free space, port I5 and tube passage to draw liquid into the nozzle from the receptacle and from which nozzle the liquid is discharged in spray-form, as well understood in the art. 30

The tube I2 in the present instance comprises two sections the inner section being preferably of metal and having a plug portion I2 at its inner end fixedly anchored within a socket I 6 provided in the bottom of the socket 1. A cir- 3f cumferential groove I! in the tube part I2 registers and provides communication between the air passage 9 and source of air supply.

The bottom or underside of the spray-head body 6 is provided with a fiat face which, when the head is screwed home on the nipple 5, seats against the top portion of the ferrule 3 in closing relation to an air vent opening I8 in said ferrule. Such seating surface of the head is of annular form preferably extending entirely around the socket I concentric with its axis and preferably comprises a yielding ring-like member I9 of cork, or other suitable material, which is set into a recess in the head bottom. The

two valve members I4 and I9 of the head are 0' adapted to have a substantially simultaneous seating on the respective parts of the ferrule 3 when the head is turned home thereon.

It is apparent that the tube I2 and passage ID of the head unit cooperate to form the liquid discharge passage of the atomizer, and that such passage as well as the air vent IS are closed against leakage of liquid from the receptacle by a simple turning home or tightening of the head unit on the receptacle, and are opened to render the atomizer operative by an unturning or loosening of the head unit on the receptacle.

It is found in practice that with the use of the present invention, the atomizer is effectually sealed against leakage of liquid from the receptacle, both through the liquid discharge passage and air vent when the spray-head unit is turned home or into stop engagement with the ferrule member 3, inasmuch as the conical valve surface M is then in seating engagement with the outer end edge of the nipple 5, and the gasket member i9 is seated against the ferrule top and in closing relation to the air vent iii. The parts are held in this closed position by frictional engagement of the seating portions. It is further found that a "cry slight turning of the head unit from its seated relation to the receptacle will open the vent and liquid passages a suficient extent to permit an operation of the atomizer.

I ish it understood that my invention is not limited to any specific construction, arrangement or form of the parts, as it is capable of numerous modifications changes without departing from the spirit of the claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent, is:

i. In an atomizer, a receptacle, a nipple mem ber fixed to its mouth portion, a spray-head unit rotatably mounted on said member and having a liquid discharge tube projecting through the member into the receptacle and also having a nozale and a liquid passage leading thereto, said unit and nipple member having parts cooperating to open and close communication between said passage and tube upon predetermined relative rotation of the unit and nipple, said nipple member having an air vent from the receptacle, and said unit and member having parts which cooperate to close said vent when said liquid passage communication is closed, and vice versa.

2. In an atomizer, a receptacle, a member mounted on its mouth and forming a nipple, a spray-head unit having a socket in its bottom in th aded engagement with said nippie, said unit having a liquid discharge tube projected into the receptacle through said nipple with its passage in communication with the bottom portion of said socket and having a nozzle and a liquid passage leading from said nozzle to said socket, and means interiorly of said socket operable upon a predetermined relative turning of said unit and member to effect a closing of the communication between said discharge tube and said passage through said socket.
