United States Patent O This invention relates to liquid scent spray devices of the kind adapted to be connected to a bottle or other container of liquid scent and comprising a spring-loaded piston in a cylinder with valve means for controlling, on movement 'of the piston, the passage of air from the cylinder into the hott-le or container pad and the ilow of scent therefrom into the cylinder to be sprayed out through an orince in the cylinder on subsequent displacement of the piston against its spring loading.

A disadvantage of this kind of scent spray is a tendency to drip or dribble, due probably to too much scent entering the cylinder, and to control the entry of air into the bottle and thereby limit the discharge of scent therefrom into the cylinder it is already known to provide a second yor auxiliary valve means operating in dependence on the movement of the piston.

Now the object yof the present invention is to provide a simplified design vof scent spray of the kind in question, which is easier and cheaper to make whilst avoiding the disadvantage of flooding of the cylinder which could cause dribbling or drops 'of scent occurring at the spray discharge orifice.

To this end according to the present invention a scent spray of the kind set forth comprises a body with a transverse partition forming the end of the cylinder portion in which moves the piston, a single valve at the end of the piston rod which freely passes through the partition and which is eective to close the passage therethrough on maximum displacement of the piston under its spring loading, a felt or like absorbent pad between such partition and a plate against which acts the spring loading the piston, and means around the piston rod and bearing on the partition, there being at least one passage way between the partition and said means providing radial or substantially radial flow paths therebetween for the continuous ow of liquid scent while the valve is unseated and the device is inverted.

Preferably the body comprises a bottle engaging part vwith a centrally apertured end Wall through which the piston -rod extends and the valve on the end thereof closes onto such end wall which bears against the partition. It is also preferred that the partition and the plate against which the loading spring acts are adapted to compress more strongly the centre of the pad, as by making the partition substantially dish shaped and the plate at.

The partition may have a peripheral llange against which bears the plate on which the loading spring acts and such flange may have an extension which engages in a cut-out portion of the plate to prevent their relative rotation.

To improve the spraying properties the plate against which the loading spring acts has a cut away portion adjacent lthe discharge oriiice in the body through which portion projects a part of the pad, and the passage way between the partition and the means abutting the same, which enable air from the cylinder to pass into the bottle or like container and also scent to pass from such bottle or container some what in the manner of a drip-feed to impregnato lor charge the pad when the valve is unseated on displacement of the piston, may be formed by one or more grooves in the surface of the partition.

In order that the invention may be clearly understood and readily carried into effect an embodiment `of scent 3,392,331 Patented June 4, 1963 ICC 2 spray is by way of example hereinafter more fully described with reference to the accompanying drawings7 in which:

FIG. l is a perspective view of the scent spray.

FIG. 2 is a longitudinal section through the scent spray.

HG. 3 is an elevation of the partition as viewed from the right hand side of FIG. 2, and

FIGS. 4 and 5 show in sectioned perspective views part yof the partition and associated plate against which acts the spring loading the piston.

The scent spray illustrated comprises a tubular body 1 which is divided by a transverse partition 2 into two substantially equal portions of which one, namely that on the right as illustrated, constitutes a cylinder in which is slideable a piston comprising an operating portion 3, cup 4- and plate 5. The other or left hand portion of the body 1 contains fast therewith a part 6 with an internal thread by means :of which the device may be screwed on to a bottle or like container of scent.

The part 6 is closed oi at one end by a wall having a central bore 7 through which passes a piston rod S which also .extends through the partition 2. On the end of the piston rod 8 is an enlargement or head 9 with an associated washer |16 constituting a valve which closes on the `end wall of the part 6 to close the passage therethrough through which the pist-on rod y8 extends.

The partition 2 has a peripheral ange 11 against the edge of which bears a circular plate 12 and preferably the flange 11 has an extension 13 which engages in a cut `out portion 14 in the plate 12 to prevent relative rotation of these two parts. The plate `12 is pressed against the edge of the ange 11 of the partition 2 by means of a spring 15 lwhich 4loads the piston 4 and normally urges it into its limit position in which the valve 9 closes the passage 7 Between the partition 2 and plate 12' is a pad 16 of felt or similar absorbent material. The arrangement is preferably such that the central portion of the pad is more strongly compressed as, for example, by making the partition dish-shaped substantially as shown while the plate 12 is flat. A cut out portion 117 of the plate 12 enables a portion 18 of the pad 16 to project into the cylinder in the region of the spray orilce 19 at the base of a recess in the body 1 and extending through the ange 11 of the partition.

Held between the partition 2 and pad 16 is a scraper disc Zit which is a light sliding .ht on the piston rod 8. While the scraper `disc 2t) is held fast against movement relative to the partition 2 provision is made for a radial or substantially radial ow path between the facing surfaces. Thus the partition 2 may be provided with one or more radial grooves Z1 which extend to `or somewhat beyond the periphery of the scraper disc Zit. Alternatively protuberances may be provided in one or other part to hold them separate sumcient to provide the -iiow paths.

ln the 'operation of the device, it is inverted and the piston is displaced by finger pressure on its operating portion `3` so unseating valve 9 and allowing some of the air compressed in the cylinder to enter the bottle whilst liquid scent or perfume therefrom may pass continuously through the bore 7 and the passage way to impregnate the pad 16. On a subsequent displacement of the piston 4 against its loading spring 15, liquid scent or perfume which has soaked into the pad 16 will be sprayed out through the orice 19. This `operation may be carried tout while the device is still inverted `for further charging of the pad with liquid or after the device has been returned to upright position.

We claim:

1. A spray device for liquid such as scent to be sprayed, comprising a tubularbody, `a piston movable in said body, aptransverse partitionin said body, sai-d partition having aY cent-rail aperture therein, a piston rod fast with said piston and extending with clearance through said aperture in said partition, a spring in said body between said piston and said partition, a valve member on said piston rod for closing said aperture in said partition on maximum displacement of said piston under the action of said spring, a plate against which said spring acting on said piston reacts, an absorbent pad between said plate and said partition, said partition having at least one radial groove in the surface thereof facing said pad, means abutting said surface of said partition and surrounding said piston rod for restricting the flow of liquid to be sprayed at all times Iwhile said valve is unseated to such liquid as will pass through said aperture, along said groove and beyond said means to charge said pad, said body having a lateral liquid discharge orifice leading from said pad to the exterior of said body.

2. A spray device as in claim 1, wherein said partition has a peripheral flange and said plate has a marginal portion bearing on said ange to `define a receptacle for said pad.

3. A spray device as in claim 2, wherein said flange has an extension and said plate has a cut-out in lwhich said extension is located to prevent relative rotation of the ange and plate.

4. A spray device according t-o claim 1, wherein said plate has a cut-out portion through which projects a portion of said pad to a region adjacent said discharge oridice to convey liquid thereto.
