Feb. 3, 1931. F. J. CARON DISPENSING DEVICE Filed April 11, 1929 Patented Feb. 3, 1931 DISPENSING DEVICE Application filed April 11,

This invention relates to dispensing devices and more particularly to soap dispensers.

The principal object of the invention is to provide a simple and efficient device which can be cheaply constructed and sold and which is adapted to be readily attached to an unvented container having a threaded neck. In a large number of the devices heretofore constructed and now on the market, in order that the liquid may flow freely from the container a suitable vent had to be provided which materially increased the cost of the container and frequently became clogged so that free flow of the liquid from the dispensing device was prevented. It is, therefore, the

object of this invention to avoid such ditficulties and to reduce the cxpense involved in the production of the device, and to this end the invention consists in a dispensing head car rying as a part thereof a venting tube, which device may be readily attached to any type of container having a screw neck.

Further objects of the invention will appear as the followingspecific description is read in connection with the accompanying drawings which form a part of this application, and in which Fig. 1 is an elevation of the device attached to a screw neck container and showing in dotted lines the location of the vent tube,

Fig. 2 is a fragmentary vertical section on a somewhat enlarged scale, and

Fig. 3 is a detail horizontal section taken on the line 33 of Fig. 2.

The container is gene-rally illustrated at 1 and is provided with a threaded neck 2. Containers of this type are very old and well known and the ordinary ketchup bottle or similar container would sufiice for the purpose of holding the supply of liquid soap, the level of which in the container is indicated at 3. The dispensing head shown at l is preferably constructed of metal although it may be conveniently made of glass or other similar frangible material and is provided with a central recess 5 having a tapered bottom 6 forming a valve seat. Extending outwardly from this seat is the discharge opening or port 7 into which is fitted loosely the stem 8 of the control valve 9. This valve is pro- 1929. Serial No. 354,326.

vided on its upper face with a circular boss 10 which enters the lower spiral of a compressiorl spring 11 which is interposed between the valve and a plug 12 screwed into the recess as shown, and having on its lower face a boss 13 corresponding to the boss 10.

This spring is of relatively light construction and only exerts sufficient tension on the valve to retain the same on its seat in any position of the container.

As shown the plug is provided with a plurality of discharge apertures 14 and a central vent aperture 15 which, as shown in Figs. 2 and 3, extends vertically through the cent r of the plug to a depth approximately midway of the thickness of the plug and then laterally to the side of the plug where it registers with a vent opening indicated at 16 and which leads to the outside of the head 4. In the vertical portion of the socket 15 is a vent tube 17 which is preferably closed at its upper end and provided with a lateral vent aperture 18.

The container may be supported in any suitable manner or the entire dispensing device may be conveniently carried around in a travelling case, as will be readily understood. When used the operator merely presses the palm of his hand against the protruding end of the valve stem 8, raising the valve ofl of its seat 6 against the tension of the spring 11 and permitting the required quantity of fiuid to flow into his hand. Upon release of the stem 8 the valve 9 will be immediately seated by the action of the spring and cut off any further flow. It will be seen that the air entering through the vent opening 16 will pass through the vent port 15 and upwardly through the tube 17 and aperture 18, displacing the fluid removed through the port 7.

In order that a fluid-tight connection may be made between the container and the dispensing head, the recess 5 is preferably enlarged and internally screw threaded as shown at 19 to receive the neck 2 and thus forming a shoulder 20 upon which a packing gasket 21 reste and receives the impact of the neck of the container as it is screwed home.

It will be readily seen that by reason of the fact that the vent tube and head constituto an entity, if container is broken no special container need be supplied as an ordiary screw neck bottle may be utilized in its place.

What I claim is:

1. In a dispensing head for fluid containers, a recessed body, said body having a discharge aperture communicating with the recess, an apertured plug bridged across said recess, a valve for controlling the discharge aperture, a spring interposed between the valve and plug for holding the valve upon its seat, said body and said plug having communicating vent apertures, and a vent tube carried by the plug and communicating with the aperture in the plug.

2. In a dispensing head for fluid containers, a recessed body having a discharge port communicating with said recess and a vent aperture extending through the wall thereof, an apertured plug bridged across said recess and having a vent aperture communicating with the vent aperture in the body, a valve for controlling said port, a spring interposed between the valve and the plug for holding the valve upon its seat, a vent tube carried by said plug and communicating with the vent aperture therein, and internal screw threads on the body for connecting the same to an unvented container.

In testimony whereof I aflix my si nature.
