J. T. GOODMAN POURING DISPENSER Filed March 1'7, 1943 Patented Jan. 30, 1945 'Y UNITED STATE sA PATENT oFFlcE James T. Goodman, Louisville, Ky. Application March 17, 1943, SerialNo'. 479,513

2 oisims. (C1. 222-477) are embodied. to adjust thev amount so poured,

within limits.

Further objects of the invention will appear l from the following description when read in connection with the accompanying drawing showing an illustrative embodiment of the invention, and wherein- Figure 1 is a side elevation;

Figure 2 is a central vertical section upon an enlarged scale broken away to shorten the showing;

Figure 3 is a transverse section on line 3-3 of Figure 2; and

Figure' 4 is a transverse section on line 4-4 of Figure 1. I

As shown the device is constructed for use with a bottle, which bottle must have a neck shaped to receive a stopper as cork or the like. It is obvious that instead of a stopper a screw cap could be applied to the device for use upon containers of other character.

As shown herein a stopper I is desirably formed of a rigid body II which may be of metal, hardened plastic or the like provided with a sleeve I2 as of cork. Passing through the stopper I0 and adapted to dip into the liquid to be dispensed contained in the container, not shown, there are shown tubes I3 and I4. The tube I3 isfor the passage of liquid and tube I4 for air supply,

which tubes are joined at I5 adjacent the lower end thereof whereat the tube I4 opens into the tube I3.

To control the flow of air into the container l through the tube I4 there is shown an air inlet I6 under control of a screw I 'I provided witha lock nut I 8. By adjusting the position of the tion 2I in a plug 22 closing the lower end of thetube I3. To cut off the ow of liquid from the device there is shown an upper seat 23 to which the ball rolls when vthe container carrying the device is tilted. Toadmit liquid to the tube I3 while pouring therefrom there are shown aplurality of holes 24, 25 and 2B. The holes 26 are provided close to the stopper I0 in order to enable the last portion of the liquid to be delivered to the tube I3 when the container is inverted.

As the liquid in the container is depleted, more and more container-held air must get into the tube I3 exchanging places with the liquid that is in the tube wheny the container is upright. Therefore a plurality of holes 24, 25 are provided to provide for the various heights when the container is tilted. To allow the lastof the liquid to escape readily from the pouring endl of tube I3, an air intake 2l is shown closely adjacent the cap 28 of the stopper.

Liquid can only iiow out of the bottle as air is admitted thereinto and therefore the adjustment of screw I'I will determine the rapidity of flow. Ifvno further provisions were made except the control. of air intake, liquid would continue to ow as long as the device was tilted or any liquid remained in the container. The ball 20 is provided to place a limit on the time during which the liquid is allowed to flow, which time is that required for the ball 20 to roll from seat 2l to seat 23. If the container be tilted sharply with reasonable uniformity, this time of iiow will be sufficiently uniform for all practical purposes to deliver a desired amount at each tilting, but will of course differ with the viscosity of the different liquids. Therefore a few trials will enable the user to adjust the screw Il so that the desired amount of liquid will flow during the roll of the ball, at each successive tilting ofthe container.

It is obvious that the projection lof the tube I3 and I4 above the closure may be made of plastlc integral with the body II, and the portions thereof within the container may be made of another material as glass with their upper ends received in the passages through the body, their ends surrounded with packing material as cork sleeves.

Minor changes may be made in the physical embodiment of the invention within the scope of the appendedclaims without departing from'the spirit of the invention. p

I claim:

1. A dispensing device for use with a tiltable container comprising, in combination: a container closure; a pouring conduit extending in both directions from the closure, opening therethrough and formed with an internal port adjacent said closure; an air inlet pipe also opening through the closure and extending in both directions therefrom, said pipe opening into the conduit adjacent its end to be Within the container to Which the closure is applied; a perforated seat at the last named end of the conduit; a ball movable ini the conduit,A normally seated upon said seat and movable .tov close said port when the device is tilted to pour liquid therefrom; said conduit formed with perforations ad.

jacent the closure; and means to adjust the rate container comprising, in combination: a container closure; a conduit passing through, and. projecting from said closure to serve as apouring.

spout; said conduit projecting below said closure a substantial distance to dip into the liquid in a. container to Which the device may be applied; said conduit having a liquid ingress opening adjacent said closure and a series of air ingress openings beginning at a point adjacent its lower end; a valve seat in said conduit; above said liquid ingress opening; a ball movable in said conduit to said valve seat when the device is tilted to pouring position; a vent tube passing through said closure parallel with5 and. opening: into said Conduit adjacent its lower end'; vent. adjusting means carried by said tube above said closure; and means at the lower end of said conduit to retain the ball therein; whereby said ball freely #u slidable in a fixed path in theconduit determines thetime of ow, and adjusted air intake determines the rate of flow of liquid from a container when appliedthereto and when the container is tilted.
