LIQUID DISPENSER Joseph Varga, Cleveland, Ohio, assignor to Albert J. Ganim, Shaker Heights, Ohio Application June 24, 1946, Serial No. 678,860

2 Claims.

This invention relates to bottle closures and particularly to the type havinga gravity actuated combination dispensing and closure valve, and is hereinafter referred to as a liquid dispenser.

The primary object of this invention is to pro Vide a liquid dispenser that forms an air tight seal, with no vent or liquid opening exposed, when in its closed condition.

Another Object is to provide a device of the type stated that will deliver liquid until a glass or similar receiver is lled to within a predetermined distance frorn the top, whereupon the flow of liquid will cease.

A further object is to provide a device that will waste no liquid through dripping, but 'will drain all of the unpoured liquid backinto the bottle or container.

Other objects are to provide arliquid dispenser that has only one moving part; that easily dismantled and cleaned; and that is neat and attractive in appearance.

These and still other objectsof .the invention will become apparent from a reading of the following specification and claims, together with the accompanying drawing, in which like parts are referred to and indicated by like reference .characters and wherein:

Figure .l is a perspective view of the liquid dispenser constituting this invention showing it mounted in a conventional vbottle neel; in its closed condition;

Figure 2 is a sectional view taken substantially along the line and in the direction of the arrows 2-2 of the Figure 1;

Figure 3 is an enlarged perspective view of the unmounted device in its tilted or open condition;

Figure 4 is a sectional View taken substantially along the line and in the direction of the arrows 4-4 of the Figure 3;

Figure 5 is a cross-sectional view taken substantially along the line and in the direction of the arrows 5-5 of the Figure 3; and

Figure 6 is an enlarged bottom view of the liquid dispenser illustrated in Figure 2.

The instant invention consists broadly of the body member II and valve member lcornbined to form the liquid dispenser illustrated in Figure 1, as it appears in its closed position when mounted on a conventional bottle 8.

In its preferred form the device is made of aluminum machined and shaped as illustrated in the accompanying drawing, although any other suitable metallic 0r plastic material, or combination thereof, may be used that will not be corroded by the contained liquid.`

The body II is made of a single piece of metal shaped as illustrated, with a tapered axial hole or air vent tube I9. The wide end of the tapered hole I9 terminates in the frusto-conical valve seat I8. The narrow or bottom end of the hole I9 has a series of longitudinal air vents or slots It, which are about 1/4 inch long.

The outer surface of the body yI I has the coniiguration shown in the Figure l; and has a top tube Il joined to the body II through the shoulder l 5; and the bottom tube I3 joined to thebody at the flange I2. The bottom tube has a threaded end I4. A sleeve 3ft of cork, or other resilient material, is mounted on the bottom tube vasillustrated in Figures 2, 3, 4 and 6.

Ilhe threads it serve to anchor the sleeve, and the flange I2 limits its upward movement on the tube I3. rlhe valve is also of one piece construction and consists of a hollow stem 2| having ya diameter that will cause it to engage the small end of the hole EE in a free sliding fit and terminating in a solid ball head 25,1having a irustoconical valve face 2t which matches and ts the valve seat I8.

A plurailty oi liquid delivery holes 23 are' bored at the base of the valve face and connect Vwith the inner duct of the hollow stem '2 I.

The stern has a circumferential groove 22 spaced about 1A; inch from its bottom end, which receives the ring shaped spring 13E, which .has an external diameter greater than that of the hole I9. v

The valve stem tube 2i is inserted in the body hole It' and the spring Si is placed in the groove 252. 'Since the spring 3i has an outside diameter greater than that of the hole I9, it acts as a loelrm ing means which limits the travel of the stern 2i and also prevents the stem 'ii from falling out of the hole i9 when the liquid dispenser is inverted.

In use theliquid dispenser is inoun ed on a t bottle as shown in Figure l. The cori; sleeve .132i

forms an air tight seal between the bottle and the' bottom tube I3, while the iiange I2 limits the depth, the device can be pushed into the bottle opening.

In the position illustrated in Figure l the rforce of gravity causes the valve stem tube 2i to travel downward until the valve face 28 seats itself on the valve seat i3 and then holds it there. This results in an'air-tiglit seal between the valve seat and face which seals 'oil'k ther contained liquidfrom the exterior and prevents evaporation.

When the bottle is tilted causing the device to assume the position indicated in Figures 3 and 4, the valve stem 2l moves forward until stopped by the circular spring SI coming in Contact with the end oi the bottom tube I3 as illustrated in Figure 4. The contained liquid flows through the hollow stein tube 2I and out through the liquid delivery holes 23.

It Will be noted that at the same time the valve stem 2| assumes a position on the lower face of the tapered body hole I9 which leaves an air 3 vent passage 24 in the wide part of the tapered hole. This air passage is continued past the narrow end of the hole, which serves as a bearing surface for the stem 2I- by means of the slotted air vents I6 as shown in Figures 4, 5 and 6.

The air needed to equalize the pressure inside and outside of the bottle enters through this passage Way to replace the dispensed liquid, thus assuring a smooth flow of liquid at all times.

When the bottle is returned to its vertical position as illustrated in Figures 1 and 2, the valve falls back into the body, closing the opening and causing any liquid in the hollow stem 2I to drain back into the bottle.

If either of the shoulders I5 or I2 are placed on the edge of the glass, or other receiver, and the bottle rested on it, as the liquid is being poured, the flow will cease as soon as the liquid rises in the glass high enough to cover the end of the air vent tube I9. Thus by varying the position of the shoulders in relation to the outlet end of the air vent tube I9, the height of the dispensed liquid can be determined ahead of time and be exactly duplicated every time the liquid is dispensed. With the dispenser illustrated, having two shoulders I5 and I2, a choice of two heights of liquid is available; however, any desired number of spaced shoulders can be used in order to adapt the device to a variety of special purposes.

Since this liquid dispenser has only two parts, which can be easily taken apart by removing the spring 3| from its seat 22, it is easy to clean and keep sanitary at all times.

It will now be clear that there is provided a device which accomplishes the objectives heretofore set forth. While the-invention has been disclosed in its preferred form, it is to be understood that the specific embodiment thereof as described and illustrated herein is not to be considered in a limited sense, and there may be other forms or modifications of the invention which should also be construed to come within the scope of the appended claims.

I claim:
